FUNDAMENTALS
[0002] [0002] The following refers, in general, to wireless communication, and more specifically to the multiplexing of control information and grouped data.
[0003] [0003] Wireless communications systems are widely implemented to provide various types of communication content, such as voice, video, packet data, sending messages, broadcasting and so on. These systems may be able to support communication with multiple users by sharing available system resources (for example, time, frequency and power). Examples of such multiple access systems include code division multiple access systems (CDMA), time division multiple access systems (TDMA), frequency division multiple access systems (FDMA) and division multiple access systems orthogonal frequency (OFDMA) (for example, a Long Term Evolution (LTE) system). A wireless multiple access communications system may include multiple base stations, each simultaneously supporting communication for multiple communication devices, which may otherwise be known as user equipment (UE).
[0004] [0004] To transmit data to a UE, a wireless communications system can use control information to grant resources to the UE for data transmissions. In some cases, control information and user data can be transmitted in the same transmission time interval (TTI) with control information included in the initial symbols of TTI. In some examples, it may be desirable to transmit control information over a narrow band while transmitting user data over a wide band. However, when transmitting control information over a narrow band and transmitting data over a wide band in the same slot, a base station can introduce a transmission gap between the two transmissions to provide the UE with time to re-tune a receiver. a narrowband mode to a broadband mode. This transmission gap can introduce latency into the system and reduce throughput. SUMMARY
[0005] [0005] A wireless communication device can switch between a distributed and grouped transmission scheme for transmitting control information and data in a way that improves throughput and reduces latency. In some cases, the base station may indicate to a UE that a grouped control information transmission scheme will be used and a monitoring standard to indicate which set of control information carries information to the UE. A base station using a grouped transmission scheme can transmit consecutive sets of control information resources (a "control information transmission grouping") that schedule subsequent downlink data transmissions that can also be grouped. In some cases, the base station may indicate to an UE that a distributed control information transmission scheme will be used. A base station using a distributed transmission scheme can transmit transmissions of control information and interleaved downlink data. Beneficially, a base station and UE can apply the techniques described in this document when scheduling data and control transmissions in a way that improves throughput and reduces latency.

[0081] [0081] A wireless communication device can switch between a grouped and distributed transmission scheme for transmitting control information and data. A base station using a grouped transmission scheme can transmit consecutive sets of control information resources (a "control information transmission grouping") that schedule subsequent downlink data transmissions that can also be grouped. A base station using a distributed transmission scheme can transmit transmissions of control information and interleaved downlink data. That is, the base station can transmit first control information and a corresponding first data transmission, then second control information and a corresponding second data transmission, and so on. A base station can indicate whether it is a distributed or bundled transmission scheme for a UE before data and control transmissions. Beneficially, the techniques described in this document can improve scheduling of data transmissions and control that improve throughput and reduce latency.
[0082] [0082] In some examples, a base station may indicate to a UE a set of control information resources that carry information to the UE. For example, when using a grouped transmission scheme, a base station may indicate a monitoring pattern that tells a UE which set of control information resources in a control information transmission cluster carries information to the UE. In some examples, a base station may indicate to the UE that a preferred beam of the UE is correlated to a symbol position of the UE control information in the control information set.
[0083] [0083] In some examples, a wireless communication device may schedule transmissions of narrowband control information in clusters to increase throughput and reduce latency. For example, a base station can transmit control information to multiple UEs in a control information transmission cluster and can transmit data to multiple UEs in a subsequent data transmission cluster, where data for multiple UEs is scheduled by the control information. In some cases, the control information is transmitted through different sets of frequencies than the corresponding data transmissions, and the corresponding data transmissions observe a re-tuning delay after the transmission of control information to allow multiple UEs to re-tune to receive the corresponding data transmissions on the different set of frequencies. Control information for additional UEs can be scheduled on resources within the re-tuning delay after the control information is scheduled for a given UE. Different control features can be associated with different transmission beams.
[0084] [0084] In one example, a base station indicates to associated UEs that the base station will use a control information transmission grouping scheme for certain transmissions (for example, system information, RACH signaling, paging, downlink or uplink and similar). The base station can then schedule control information for multiple UEs in a control information transmission cluster. The grouping of control information can include multiple sets of control channel resources for multiple UEs. In some cases, the length of the control information transmission cluster is based, at least in part, on a re-tuning delay (for example, an average re-tuning delay, a worst-case re-tuning delay, or indicated re-tuning delays) explicitly by multiple UEs) or a number of supported beams for control information. The control information in the control information transmission cluster can be used to schedule subsequent data transmissions to the multiple UEs (for example, in a data transmission cluster). In some cases, a first set of control channel resources that carry control information to a first UE can be separated by data resources for a corresponding data transmission for a period of time equivalent to the UE's re-tuning delay (or " a re-tuning delay period "). The remaining control channel resource sets for other UEs can be located in time within the time period between the first control channel resource set and the data resources.
[0085] [0085] In some cases, signaling techniques may be employed to support a grouping scheme for transmitting control information. For example, a base station can direct a UE to monitor a particular beam and / or determine symbol periods or slots in a grouping of transmitting control information to control information (for example, sending a beam indication or beam direction). In some examples, the indicated beam corresponds to a set of control channel resources that includes one or a set of symbol periods in the control information transmission grouping. For example, a UE that receives an indication to monitor a second beam also for monitoring a second symbol or slot period in the control information transmission cluster. In other examples, a UE may identify a preferred transmission beam based on synchronization signal block (SS) transmissions or reference signal transmissions (CSI-RS) of beamed channel status information (CSI) ) and can implicitly determine that a control channel resource set that carries control information to the UE in the control information set transmission cluster starts at a symbol period corresponding to the preferred transmission beam index. In some cases, the control information transmission cluster signaling can be transmitted in a master information block (MIB), a system information block (SIB), radio resource control signaling (RRC), an element control (CE) media access control (MAC) or downlink control (DCI) information.
[0086] [0086] The particulars of the disclosure introduced above are further described below in the context of a wireless communication system. Specific examples are then described of an exemplary process flow for multiplexing data and grouped control information. These and other features of the disclosure are further illustrated and described with reference to device diagrams, system diagrams and flowcharts that refer to the multiplexing of data and grouped control information.
[0087] [0087] Figure 1 illustrates an example of a wireless communications system 100 that supports multiplexing of data and control information grouped according to various aspects of the present disclosure. The wireless communications system 100 includes base stations 105, UEs 115 and a main network 130. In some instances, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced network (LTE-A), or a New Radio (NR) 5G network. In some cases, the wireless communications system 100 can support enhanced broadband communications, ultra-reliable communications (i.e., mission-critical), low-latency communications, and communications with low-cost, low-complexity devices.
[0088] [0088] Base stations 105 can communicate wirelessly with UEs 115 through one or more base station antennas. Each base station 105 can provide communication coverage for a respective geographic coverage area 110. The communication links 125 shown in the wireless communication system 100 can include uplink transmissions from an UE 115 to a base station 105 or downlink transmissions, from a base station 105 to a UE
[0089] [0089] UEs 115 can be dispersed via wireless communication systems 100, and each UE 115 can be stationary or mobile. An UE 115 can also be called a mobile station, subscriber station, mobile unit, subscriber unit, wireless unit, remote unit, mobile device, wireless device, wireless communication device, remote device, mobile subscriber station, access terminal, mobile terminal, wireless terminal, remote terminal, handset, user agent, mobile client, customer or some other suitable terminology. An UE 115 can also be a cell phone, a personal digital assistant (PDA), a wireless modem, a wireless communication device, a portable device, a tablet computer, a laptop computer, a cordless phone , a personal electronic device, a portable device, a personal computer, a wireless local loop station (WLL), an Internet of Things (IoT) device, an Internet of Everything (IoE) device, a type of machine (MTC), an accessory, an automobile or the like.
[0090] [0090] In some cases, a UE 115 may also be able to communicate directly with other UEs (for example, using a point-to-point protocol (P2P) or device to device (D2D)). One or more of a group of UEs 115 using D2D communications can be within the coverage area 110 of a cell. Other UEs 115 in that group may be outside coverage area 110 of a cell or otherwise unable to receive transmissions from a base station 105. In some cases, groups of UEs 115 communicating via communications of D2D can use a one to many (1: M) system in which each UE 115 transmits to each other UE 115 in the group. In some cases, a base station 105 makes it easy to schedule resources for D2D communications. In other cases, D2D communications are performed independently of a 105 base station.
[0091] [0091] Some UEs 115, such as MTC or loT devices, can be low cost or low complexity devices, and can provide automated communication between machines, that is, Machine to Machine (M2M) communication. M2M or MTC can refer to data communication technologies that allow devices to communicate with each other or with a base station without human intervention. For example, M2M or MTC can refer to communications from devices that integrate sensors or meters to measure or capture information and relay that information to a central server or application program that can use the information or present the information to humans who interact with the program or application. Some UEs 115 can be designed to collect information or enable automated machine behavior. Examples of applications for TCM devices include smart metering, inventory monitoring, water level monitoring, equipment monitoring, healthcare monitoring, wildlife monitoring, geological and climate event monitoring, fleet tracking and management, remote security detection, physical access control and transaction-based business charging.
[0092] [0092] The base stations 105 can communicate with the central network 130 and with each other. For example, base stations 105 can interface with central network 130 through backhaul links 132 (e.g., SI, etc.). Base stations 105 can communicate with each other via backhaul links 134 (for example, X2, etc.) directly or indirectly (for example, through central network 130). Base stations 105 can perform radio scheduling and configuration for communication with UEs 115, or they can operate under the control of a base station controller (not shown). In some examples, base stations 105 may be macrocells, small cells, hot spots, or the like. Base stations 105 can also be referred to as eNodeBs (eNBs) 105, next generation NodeBs (gNBs) 105, etc.
[0093] [0093] In some cases, the 00 wireless communications system may be a packet-based network that operates according to a layered protocol stack. At the user level, communications at the Packet Data Convergence Protocol (PDCP) layer or at the carrier can be based on IP. A Radio Link Control (RLC) layer can, in some cases, perform reassembly and segmentation of the packet to communicate through logical channels. A Media Access Control (MAC) layer can perform multiplexing and priority manipulation of logical channels in transport channels. The MAC layer can also use Hybrid Automatic Retry Request (HARQ) to provide retransmission at the MAC layer to improve link efficiency. In the control plane, the Radio Resource Control (RRC) protocol layer can provide for establishing, configuring and maintaining an RRC connection between an UE 115 and a base station 105 or central network 130 that supports carriers radio for user plan data. In the Physical layer (PHY), transport channels can be mapped to physical channels.
[0094] [0094] The wireless communication system 100 can support the operation in multiple cells or carriers, a feature that can be referred to as carrier aggregation (CA) or multi-port operation. A carrier can also be referred to as a component (CC) carrier, a layer, a channel, etc. The terms "carrier", "component carrier" and "channel" can be used interchangeably in this document. A UE 115 can be configured with multiple downlink CCs and one or more uplink CCs for carrier aggregation. Carrier aggregation can be used with both frequency division duplex (FDD) and time division duplex (TDD) component carriers.
[0095] [0095] In some cases, the wireless communications system 100 may use enhanced component carriers (eCCs). An eCC can be characterized by one or more features that include: wider bandwidth, shorter symbol duration,
[0096] [0096] In some cases, an eCC may use a different symbol duration than other CCs, which may include the use of a reduced symbol duration compared to the symbol durations of the other CCs. A shorter symbol life can be associated with greater subcarrier spacing. A TTI in an eCC can consist of one or multiple symbols. In some cases, the duration of TTI (that is, the number of symbols in a TTI) can be variable. In some cases, an eCC may use a different symbol duration than other CCs, which may include the use of a reduced symbol duration compared to the symbol durations of the other CCs. A shorter symbol life is associated with greater subcarrier spacing. A device, such as an UE 115 or base station 105, that uses eCCs can transmit broadband signals (for example, 20, 40, 60, 80 MHz, etc.) in short symbol durations (for example, 16.67 microseconds). An eCC TTI can consist of one or multiple symbols. In some cases, the duration of TTI (that is, the number of symbols in a TTI) can be variable.
[0097] [0097] A shared radio frequency spectrum band can be used in an NR shared spectrum system. For example, a shared NR spectrum can use any combination of licensed, shared and unlicensed spectra, among others. The flexibility of subcarrier spacing and eCC symbol duration can allow the use of eCC across multiple spectra. In some examples, the shared NR spectrum can increase spectral efficiency and spectrum utilization, specifically through vertical (eg through frequency) and dynamic horizontal (eg through time) sharing of resources. When operating on unlicensed radio spectrum bands, wireless devices such as base stations 105 and UEs 115 can employ listening before speaking (LBT) procedures to ensure that the channel is cleared before transmitting data. In some cases, operations on unlicensed bands may be based on a CA configuration in combination with CCs that operate on a licensed band. Unlicensed spectrum operations may include downlink transmissions, uplink transmissions, or both. Duplexing in unlicensed spectrum can be based on FDD, TDD, or a combination of both.
[0098] [0098] Wireless communication system 100 can operate in an ultra-high frequency (UHF) region
[0099] [0099] The wireless communications system 100 can support millimeter wave (mmW) communications between UEs 115 and base stations 105. Devices operating in mmW, SHF or EHF bands can have multiple antennas to allow the formation of beams . Beaming can also be employed outside these frequency bands (for example, in any scenario where greater cell coverage is desired). That is, a base station 105 can use multiple antennas or antenna arrays to conduct beamforming operations for directional communications with a UE 115. Beam formation (which can also be referred to as spatial filtration or directional transmission) is a signal processing technique that can be used on a transmitter (for example, a base station 105) to shape and / or direct a general antenna beam towards a target receiver (for example, a UE 115). This can be achieved by combining elements in an antenna array in such a way that signals transmitted at particular angles experience constructive interference while others experience destructive interference. For example, base station 105 may have an array of antennas with a number of rows and columns of antenna ports that base station 105 can use for beaming in its communication with UE 115. Signals can be transmitted multiple times in different directions (for example, each transmission beams differently). An mmW receiver (for example, a
[00100] [00100] Wireless multiple input and multiple output (MIMO) systems use a transmission scheme between a transmitter (for example, a base station 105) and a receiver (for example, a UE 115), in which both the transmitter and receiver are equipped with multiple antennas. In some cases, the antennas of a 105 or UE 115 base station may be located within one or more antenna arrays, which can support beam formation or MIMO operation. One or more base station antennas or antenna arrays can be placed in an antenna mount, such as an antenna tower. In some cases, antennas or antenna arrays associated with a base station 105 may be located in several geographic locations. A base station 105 can use multiple antennas or antenna arrays to conduct beamforming operations for directional communications with an UE 115.
[00101] [00101] Wireless communications system 100 can schedule resources to support both uplink and downlink transmissions. For example, wireless communications system 100 may allocate a first set of resources for downlink transmission and a second set of resources for uplink transmissions. If the wireless communications system 100 uses frequency division duplexing (FDD) for communications, then uplink and downlink transmissions can occur simultaneously. That is, the wireless communications system 100 can allocate a first set of frequencies for uplink transmissions and a second set of frequencies for downlink transmissions. If the wireless communications system 100 uses time division duplexing (TDD) for communications, then uplink and downlink transmissions may not occur simultaneously. That is, the wireless communication system 100 can allocate all frequency resources for downlink transmissions during a first interval (for example, one or more subframes) and can allocate all frequency resources for uplink transmissions during a second interval (for example, a subsequent subframe). The wireless communications system 100 can also use a combination of FDD and TDD techniques.
[00102] [00102] The resources allocated for uplink and downlink transmissions can be additionally partitioned into control and data resources. Resources that carry uplink transmissions of control information can be denoted as PUCCH, while resources that carry uplink data transmissions can be denoted as the physical uplink shared channel (PUSCH). In some cases, a wireless communications system 100 may allocate a first set of resources in a TTI for control information (the first set of resources may be referred to as control resources, a set of control channel resources, a set of control resources (CORESET), a PDCCH, a PUCCH or the like) and can allocate the remaining subsequent resources for data transmissions (the remaining resources can be referred to as data resources, a PDSCH, a PUSCH or similar). In other cases, the wireless communication system 100 can interleave control and data resources into a TTI.
[00103] [00103] A UE 115 can synchronize with wireless communication system 100 using synchronization signals or channels transmitted by a network entity (e.g., cell acquisition). In some examples, a base station 105 can transmit synchronization signal blocks (SS) that contain discovery reference signals. SS blocks can include a primary sync signal (PSS), a secondary sync signal (SSS) or a physical broadcast channel (PBCH). A UE 115 attempting to access a wireless network can perform an initial cell search by detecting a PSS from a base station 105. The PSS can enable symbol timing synchronization and can indicate a layer identity value physical. The PSS can be used to acquire timing and frequency as well as a physical layer identifier. The UE 115 can then receive an SSS. SSS can enable radio frame synchronization, and can provide a cell group identity value. The cell group identity value can be combined with the physical layer identifier to form the physical cell identifier (PCID), which identifies the cell. SSS can also enable the detection of a duplex mode and a cyclic prefix length (CP). An SSS can be used to acquire other system information (for example, subframe index). The PBCH can be used to acquire additional system information needed for acquisition (for example, bandwidth, frame index, etc.). For example, the PBCH can load a master information block (MIB) and one or more system information blocks (SIBs) for a given cell.
[00104] [00104] Due to the fact that a base station 105 may not know the locations of devices attempting to synchronize with a base station cell, SS blocks can be transmitted consecutively (for example, over multiple periods of time). symbol) in a swept beam. In some cases, base station 105 transmits eight SS blocks (although in other examples, base station 105 can transmit up to 64 SS blocks) in a beam-scanned manner. Similar to base station 105, a UE 115 can contain multiple antennas and can weight its antennas to form multiple receiving beams. The UE 115 can scan receive beams as it receives one or more of the SS blocks and determine a suitable or preferred downlink beam pair (for example, including the best performance combination of the downlink transmit beam and the forward beam). downlink receiving). The UE 115 can then report the identified transmission beam to the
[00105] [00105] Wireless communication system 100 can also support energy saving techniques. For example, a base station 105 can transmit control information over a narrow bandwidth, where the control information schedules data transmissions to an UE 115 over a larger bandwidth. In this way, an UE 115 can conserve energy since the monitoring of larger bandwidths is often associated with the use of higher power in the UE (for example, a larger number of samples can be taken by the UE to receive the bandwidth signals. bigger). Since an UE 115 identifies the desired control information for the UE 115 in the narrowband, the UE 115 can identify a subsequent location (for example, frequency and time location) to receive data from base station 105 via wider band. In some cases, the control information (for example, a downlink lease) indicates the location for the UE 115. However, the UE 115 can first reconfigure the receiving chain from a narrowband configuration to a broadband configuration. before receiving broadband data. Transitioning, or re-tuning, the receiving chain from a narrow band to a broadband configuration usually takes a certain amount of time (for example, tens of microseconds to milliseconds). The time it takes for an UE to transition, or re-tune, a receiving chain can be referred to as "re-tune delay". Therefore,
[00106] [00106] In some cases, aspects of the wireless communications system 100 including a base station 105 or UE 115 may employ techniques to utilize the transmission gap between narrowband control transmission and broadband data transmission discussed above . For example, a base station 105 can schedule transmissions of control information to other UEs 115 (for example, associated with other beams) during the transmission gap. In this way, the latency introduced in the wireless communications system 100 by a transmission gap can be reduced.
[00107] [00107] Figure 2 illustrates an example of a wireless communications subsystem 200 that supports multiplexing of data and control information grouped according to various aspects of the present disclosure. The wireless communications subsystem 200 can include UE 115- a, UE 115-b, and base station 105-a, which can be examples of a UE 115 or a base station 105 and can communicate with each other as described above reference to Figure 1. The wire communications subsystem 200 may include a communication link 205, which can be used to transmit control information 210 and data 215.
[00108] [00108] In some instances, base station 105- successfully transmits SS blocks in a beam-scanned mode (for example, transmits a first SS block in a first beam / beam direction, a second SS block in a second beam / beam direction, and so on) for detection by UEs, as discussed with reference to Figure 1. The UE 115-a and UE 115-b can identify a preferred beam (for example, as part of a pair of downlink beams) based on the transmitted SS blocks and can indicate their respective preferences for base station 105-a, which can use the preferred beams for subsequent transmissions to UE 115-a and UE 115-b. For example, UE 115-a may prefer a first beam while UE 115-b may prefer a second beam.
[00109] [00109] Base station 105-a can also use a narrowband control channel that schedules a broadband data channel for certain transmissions, as discussed above with reference to Figure 1. For example, base station 105 -a can configure UEs 115-a and 115-b for respective sets of control channel resources that are respective narrow band subsets of a carrier bandwidth, while data transmissions can use a wider bandwidth up to carrier bandwidth as allocated by downlink control information carried by the control channel resource sets. In some examples, a control channel resource set is assigned to a UE 115 by parameters that define a number of symbol periods and frequency bandwidth for the control channel resource set. The UE 115 then monitors the control channel feature set at the beginning of each slot for downlink control information that indicates, for example, SIB messages, random access response messages, paging messages and / or downlink or uplink lease messages using this configuration.
[00110] [00110] In some examples, the UE 115-a and UE 115-b can determine a re-tuning delay to re-tune a receiver from a narrowband receiving configuration to a broadband receiving configuration, and can each transmit an indication of their respective re-tuning delays for base station 105-a. The base station 105-a can use the received indications to determine a delay between transmitting control information to the UE 115-a and UE 115-b and transmitting data scheduled by the control information. In other examples, a fixed delay between narrowband control channel transmissions and data transmissions can be applied by base station 105-a.
[00111] [00111] In some cases, base station 105-a may indicate to UEs 115-a and 115-b that a grouping mode of control information should be used for transmitting control information. For example, base station 105-a can use the grouping mode of control information for certain types of transmissions, such as SIB messages, RACH response messages, paging messages or user data. In some cases, base station 105-a may deploy a pooled transmission scheme when there is insufficient space for PDSCH transmissions to be transmitted with a pooled SS block transmission. For example, base station 105-a may have the option to configure an RMSI CORESET and its associated PDSCH to group PDSCH together due to the lack of space for PDSCH in a cluster of SSB transmissions.
[00112] [00112] In some cases, base station 105-a can schedule UE 115-a and UE 115-b to receive information according to a grouped transmission scheme based on re-tuning periods of UE 115-a and EU 115-b . For example, base station 105-a can schedule control information for UE 115-a on a first set of control channel resources and a corresponding data transmission to UE 115-a on data resources that are time-separated of the first set of control channel features for a period of time (or "a re-tuning delay period") that is equivalent to at least the re-tuning delay indicated by UE 115-a. Base station 105-a can also schedule control information for UE 115-b in a second set of control channel features in additional control features during the re-tuning delay period. In some cases, base station 105-a may also schedule control information for additional UEs in subsequent control channel resource sets during the re-tuning delay period until all available control resources during the re-tuning delay period tuning are used. In some cases, the first, second, and / or third set of control channel resources may comprise a transmission grouping of control information.
[00113] [00113] Base station 105-a can subsequently receive user data for transmission to UE 115-a and UE 115-b. Consequently, base station 105 can transmit control information to UE 115-a which schedules user data to UE 115-a in a first set of control channel resources and subsequently transmit control information to UE 115-b which schedules user data for UE 115-b in a second set of control channel resources within the same control information transmission grouping. In some cases, the control information transmission cluster encompasses a single slot, while in other cases, the transmission of control information encompasses multiple slots. Each control channel resource in the control information transmission cluster can be associated with a transmission beam. For example, base station 105-a can transmit control information to UE 115-a in a first portion of a slot in a first beam direction and control information to UE 115-b in a second portion of the slot in a second beam direction.
[00114] [00114] In some cases, an UE may apply an assumption of quasi-co-location between an SS block and a set of PDCCH occasions that the UE monitors. For example, UEs, such as UE 115-a and UE 115-b, can identify locations for their control information within the slot based on their corresponding set of control channel features and a beam index (for example, a beam index). SS beam or CSI-RS beam index). For example, the UE 115-a may have beam 1 selected as a preferred beam and may determine that its control channel feature set is in a first portion of a slot and transmitted using beam 1. In some examples, a locating a set of control channel resources (for example, PDCCH) can be an SSB index function (for example, RMSI CORESET transmission standard 1). Similarly, UE 115-b can have beam 2 selected and can determine that its control channel resource set is in a second portion of the slot and transmitted using beam 2. As discussed above, the resource set control channel for UE 115-b may be located after UE 115-a control channel feature set, but within a subsequent delay period. In this way, base station 105-a can use UE 115-a re-tuning delay period and reduce system latency.
[00115] [00115] In some cases, the lengths of each portion of the slot can be determined by the length of the corresponding control channel feature sets. For example, each control channel resource set can have a symbol period duration and therefore, in a grouped control information transmission mode, each UE can identify its control channel resource set by identifying itself a slot symbol period corresponding to your preferred beam index. In other cases, each control channel resource set may have a duration of multiple symbol periods (for example, 2 symbol periods) and a first UE can identify its control channel resource set by identifying the first multiple symbol periods (for example, the first and second symbol periods), a second UE can identify its set of control channel resources by identifying the next multiple symbol periods (for example, the third and fourth symbol periods) and so on.
[00116] [00116] In some cases, the slots can be additionally partitioned into mini-slots, which can be defined as one or more symbol periods and can be indexed within each slot. In some cases, a control information transmission cluster encompasses multiple slots, or mini-slots, and control channel resource sets encompass full slots, or mini-slots, in which case, a UE can identify its set of resources control channel by identifying a slot number or mini-slot number that corresponds to a preferred beam direction. For example, a first UE that prefers beam 1 may identify its set of control channel resources by identifying the first slot or first set of slots in the control information transmission cluster, a second UE that prefers beam 2 may identify your set of control channel features in the next slot or set of slots, and so on.
[00117] [00117] In other cases, base station 105-a can direct UE 115-a and UE 115-b to monitor a specific beam or set of beams within the control information transmission cluster. For example, base station 105-a can direct UE 115-a to monitor a first beam direction that has a first index of the control information transmission cluster. After identifying your control information, UE 115-a and UE 115-b can determine a location for a corresponding data transmission. In some cases, the control information for UE 115-a in a first set of control channel resources indicates the location of the corresponding data transmission for UE 115-a and control information for UE 115-b in a second set of resources control channel indicates the location of the corresponding data transmission for UE 115-b. In some examples, the control information indicates that the location of the corresponding data transmission is in the same slot as the control information, which can be referred to as scheduling between symbols. Although in other examples the control information indicates that the location of the corresponding data transmission is in a different slot from the control information, which can be referred to as scheduling between slots. For example, the control information may indicate an initial symbol period within the slot for data transmission or the deviation between the symbol period that carries the control information and a first symbol period of data transmission, which may be in the same or a subsequent slot.
[00118] [00118] Figure 3 illustrates an example of a transmission configuration 300 of control information and multiplexed data according to various aspects of the present disclosure. The transmission configuration 300 can illustrate aspects of a transmission between an UE 115 and a base station 105, as described above with reference to
[00119] [00119] A base station can use 305 control channel feature sets to transmit control information to one or more UEs. For example, the first set of control channel resources 305-a can load control information to a first UE, the second set of control channel resources 305-b can load control information to a second UE, and so on . In some cases, control channel resource sets 305 are transmitted over a narrow bandwidth. By transmitting sets of 305 control channel resources over a narrow bandwidth, a UE can save energy by monitoring only the narrow bandwidth, for example, by taking fewer samples and a base station can save similarly. In some cases, the base station transmits control information included in the first set of control channel features 305-a in a first beam direction, control information included in the second set of control channel features 305-b in one second beam direction and so on.
[00120] [00120] A base station can use data resources 310 to transmit user data to one or more UEs. In some cases, control channel resource sets 305 are used to schedule data resources 310 to a UE. For example, the control channel resource set 305-a can schedule data resources 310-a for the first UE. A base station can employ inter-symbol or slot-based scheduling based on whether a UE supports inter-symbol or slot-based scheduling. In some cases, data resources 310 are transmitted over a larger or different bandwidth, for example, using different subcarriers, from the 305 control channel resource sets. Using a larger bandwidth for data transmissions. data, a base station can communicate more data than with a narrow bandwidth. In other cases, the data resources 310 are transmitted over the same bandwidth as the control channel resource sets 305.
[00121] [00121] In order to receive the highest bandwidth data transmissions, a UE can re-tune a receiver from a narrowband receiving mode to a broadband receiving mode. This re-tuning delay period 315 can be associated with a certain amount of time (for example, from microseconds to milliseconds) and can vary from one UE to another. Due to the re-tuning delay period 315, a base station 105 can separate control transmissions and data transmission for a period of time that is equivalent to at least the re-tuning delay period 315. For example, the base station may transmit control information to a first UE during the first set of control channel resources 305-a and can schedule / transmit data to the first UE during first data resources 310-a after the 315-a re-tuning delay period has passed . In some cases, the UEs indicate to the base station a value corresponding to the respective re-tuning delay period 315. In other cases, the base station may use a worst-case or average value to determine the re-tuning delay period 315. In some cases, re-tuning delay periods 315 can result in portions of a slot that are unused.
[00122] [00122] Although the 305-aa 305-n control channel feature sets are portrayed as using frequency features that share a common size and frequency bandwidth, in some cases the 305- control channel feature sets aa 305-n can be deviated from each other, (for example, in different subcarrier regions), and / or different non-overlapping bandwidths. Similarly, data resources 310-a to 310-n can be offset from each other (for example, in different subcarrier regions) and / or different non-overlapping bandwidths. In some cases, data resources 310-a may be the same size or smaller than the control channel resource set 305-a.
[00123] [00123] Figure 4 illustrates an example of a 400 transmission configuration of grouped control information and multiplexed data according to various aspects of the present disclosure. The transmission configuration 400 can illustrate aspects of a transmission between a UE 115 and a base station 105, as described above with reference to Figures 1 to 2. The transmission configuration 400 can include a control information transmission cluster 420 that includes the first set of control channel features 405-a, the second set of control channel features 405-b, the third set of control channel features 405-n. Transmission configuration 400 can also include the first data resources 410-a, second data resource 410-b, third data resources 410-n, first period of re-tuning delay 415-a, second period of re-tuning delay 415 -be third tuning delay period 415-n. In some cases, the transmission configuration 400 can be configured according to symbol periods 425 and slots 430.
[00124] [00124] Transmission configuration 400 can be an example of a grouped scheme for transmitting control information and user data. In some cases, the base station can switch between the distributed way of transmitting control information and data, as depicted in Figure 3, and the control information transmission grouping scheme. For example, the base station may indicate to the UEs served that the control information transmission grouping scheme is being used during an initial access procedure, through signaling in a master information block (MIB), system information (SIB), radio resource control (RRC) signaling, a media access control (MAC) control element (MAC), or downlink control (DCI) information. The base station can similarly indicate to UEs served when the distributed way of transmitting control information and data is being used. In some instances, the control information transmission grouping scheme is used to schedule multiple UEs during an active time in a discontinuous receiving cycle (DRX).
[00125] [00125] In some examples, a base station can schedule data transmissions and control in clusters. For example, a base station can schedule pooled associated and transmitting data transmissions after determining that there are insufficient resources to transmit data transmissions (or PDSCH) in an SS block transmission pool. By scheduling data transmission and control in this way, the base station can reduce the latency introduced into the wireless system for 415 re-tuning delay periods. For example, after indicating to one or more UEs that a grouped transmission scheme is being used, the base station can schedule a control information transmission pool 420 that includes the first 405-a control channel feature set and 405-b 405-n control channel feature sets. In some instances, the 405-b to 405-n control channel feature sets may span a time equivalent to the first 415-a re-tuning delay subsequent to the first 405-a control channel feature set. In other examples, the 405-b 405-n control channel feature sets may span a longer period of time than the first 415- a re-tuning delay, which can be selected based on the number of beams and duration of each of the 405 control channel resource sets. The grouped control channel resource sets 405-aa 405-n can schedule grouped data resources 410-aa 410-n for respective UEs.
[00126] [00126] A base station may indicate, for one or more UEs, techniques for identifying sets of control channel resources in the control information transmission cluster 420. For example, the base station may indicate to a UE a beam specific transmission points for the UE to monitor for control information during a control information transmission cluster 420. For example, the base station may instruct a first UE to monitor a first transmission beam direction, and the first UE may monitor the 405-a control channel feature set as discussed above. In an example, the base station can indicate the transmission beam to monitor by providing an index to the control information transmission cluster 420, or a bitmap indicating the beams within the control information transmission cluster 420 to be monitored. In other cases, the base station may transmit to a UE a bitmap that indicates how the beams, such as an SS beam or a CSI-RS beam, map in symbol periods, slots, or mini-slots of a transmission cluster of control information 420. The base station can also indicate to a UE to monitor the corresponding symbol beam, period (or periods), slot (or slots), or mini-slot (or mini-slots) based on a beam preferential option selected by the UE.
[00127] [00127] In one example, a base station can transmit consecutive SS blocks and receive indications for preferred transmission beams for one or more UEs, as discussed above with reference to Figures 1 and
[00128] [00128] In some examples, the first UE may indicate a preference for a base station for a first beam (for example, by sending a beam index) and the second UE may indicate a preference for a base station for a base station. second beam. The base station can then schedule and transmit control information to the first UE in the first set of control channel resources 405-a which is transmitted using a first beam and control information to the second UE in the second set control channel features 405-b which is transmitted using a second beam. After indicating a preference for the first beam, the first UE can monitor the first beam and the first symbol period or first symbol periods of a 430 slot. In some cases, a UE can continuously monitor slots or can monitor designated slots for information of control.
[00129] [00129] The base station can then transmit the control information in a swept beam mode, the first set of 405-a control channel resources being transmitted using a first beam and the second set of resources control channel 405-b is transmitted using a second beam. After the base station transmits the control information transmission cluster 420, the first UE can identify its control information in the first set of control channel resources 405-a by monitoring the first beam and the first period (or periods ) of the slot symbol. Similarly, the second UE can identify its control information in the second set of 405-b control channel resources by monitoring the second beam and the next symbol period (or periods), and so on for the remaining UEs. control information transmission group 420. While control channel resource sets 405 can be scheduled according to symbol periods, in some cases, control channel resource sets 405 and data resources can be scheduled. scheduled according to slots, or mini-slots, in which case a beam index can correspond to a slot or mini-slot.
[00130] [00130] In some cases, the 405-aa 405-n control channel resource sets are transmitted so that the first 405-a control channel resource set is transmitted in a first direction, the second resource set control channel 405-b is transmitted in a second direction and so on. In other cases, the first set of control channel resources 405-a can be transmitted in a direction that is not the first direction, the set of control channel resources 405-b can be transmitted in a direction that is not the second direction and so on. For example, the first set of control channel resources 405-a can be transmitted in a second direction and the second set of control channel resources 405-b can be transmitted in a first direction based on the re-tuning delay period. 415-a for the first UE which is greater or less than the re-tuning delay period 415-b for the second UE, in which case a UE can monitor by a set of 405 control channel resources in a beam and can do not monitor a symbol period that corresponds to the beam.
[00131] [00131] After decoding the control information in the assigned control channel resource set 405, a UE can identify corresponding data resources. For example, the first UE can decode control information in the first set of control channel resources 405-a and the decoded control information can indicate to the UE that a corresponding data transmission is located in the first data resources 410-a. In some cases and as pictured, a data location in a data transmission cluster can correspond to a location in a set of control channel features used to schedule the data. For example, the first set of control channel resources 405-a can be located at the first position of the control information transmission group 420 and data scheduled by the set of control channel resources 405-a can be included in the first resources 410-a database. Similarly, data scheduled during the control channel resource set 405-b, located in the second position of the control information transmission cluster 420 can schedule data during data resources 410, located in the second position of the control cluster. data transmission and so on.
[00132] [00132] Figure 5 illustrates an example of a configuration of transmission 500 of grouped control information and multiplexed data according to various aspects of the present disclosure. The transmission configuration 500 can illustrate aspects of a transmission between a UE 115 and a base station 105, as described above with reference to Figures 1 to 2. The transmission configuration 500 can include a transmission grouping of control information 520 that includes the first set of control channel features 505-a, the second set of control channel features 505-b, third sets of control channel features 505-n. The transmission configuration 500 may also include first data resources 510-a, second data resource 510-b, third data resources 510-n, first period of re-tuning delay 515-a, second period of re-tuning delay 515- b and third 515-n re-tuning delay period.
[00133] [00133] In some examples, a location of a control channel resource set 505 in a transmission grouping of control information 520 does not necessarily correspond to a data resource location in a data resource set 525. For example , a base station can transmit the first set of control channel resources 505-a at the first control information transmission pool location 520, the second set of control channel resources 505-b at the second control pool location control information transmission 520, and third control channel resource set 505-c at the third control information transmission cluster location 520, while transmitting data to a first UE scheduled by the first control channel resource set 505 -a on the first data resource 510-a, data for a second UE scheduled by the second set of control channel resources 505-b on t third data resource 510-c, and data for a third UE scheduled by the third set of control channel resources 505-c on the second data resource 510-b
[00134] [00134] As pictured, a location of a control channel resource set 505 in a transmission grouping of control information 520 does not necessarily correspond to a data resource location in a data resource set 525. For example, a base station can transmit the first set of control channel resources 505-a at the first control information transmission pool location 520, second set of control channel resources 505-b at the second transmission transmission pool location control information 520 and third set of control channel resources 505-c at the third transmission information transmission cluster location 520, while transmitting data to a first UE scheduled by the first set of control channel resources 505-a on first data resource 510-a, data for a second UE scheduled by the second set of control channel resources 505-b in tert third data resource 510-c, and data for a third UE scheduled by the third set of control channel resources 505-c in the second data resource 510-b. By scheduling data resources for certain UEs at different locations within the data resource set 525 than in the control information transmission cluster 520, a base station can accommodate for scenarios where a UE associated with a second beam and the second set of control channel resources 505-b has a 515-b re-tuning delay period longer than the 515-b re-tuning delay period for the third UE associated with the third beam and the third channel resource set control 505-c.
[00135] [00135] Figure 6 illustrates an example of a process flow 600 for multiplexing data and control information grouped according to various aspects of the present disclosure. Process flow 600 can be carried out by UE 115-b and base station 105-b, which can be an example of an UE 115 and base station 105 described above with reference to Figures 1 to 2. In some examples, the station -base 105-b operating in a low power mode can transmit control information to one or more UEs, including UE 115-c using a control information transmission grouping scheme.
[00136] [00136] In step 605, the base station 105-b can transmit synchronization and / or reference signals. In some cases, base station 105-b transmits consecutive SS blocks in a beam-scanned manner. Base station 105b can similarly transmit reference signals, such as CSI-RS, in a beam-scanned manner.
[00137] [00137] In steps 610 to 630, base station 105-b and UE 115-c can exchange exchange configuration signaling. In some cases, base station 105-b transmits its configuration signaling to UE 115-c in a MIB, a SIB, RRC signaling, MAC CE, or in DCI. For example, base station 105-b can transmit configuration signaling that includes an indication of a set of control channel features, a control information transmission scheme (for example, distributed transmission scheme or a transmission scheme pooled), and / or a monitoring standard for control channel feature sets. In some cases, base station 105-b indicates a pooled transmission scheme after determining that there are insufficient resources available for data transmissions (for example, PDSCH transmissions) in a pool that transmits SS blocks. The UE 115-c can transmit configuration signaling which includes a re-tuning delay and / or a preferred beam direction.
[00138] [00138] In step 610, base station 105-b can indicate to UE 115-c that base station 105-b is transmitting a control channel using a narrow band (for example, by configuring a narrowband control channel feature set for UE 115-c). In some cases, the UE 115-c can determine that downlink control information must be transmitted using a narrow bandwidth and can configure a receiver to receive a narrow frequency range to save power.
[00139] [00139] In step 615, base station 105-c can indicate to UE 115-c that a grouping scheme will be used for transmitting control information. In some examples, the grouping scheme for transmitting control information is implemented as discussed with reference to Figure 4.
[00140] [00140] In step 620, base station 105-c can also indicate a standard for UE 115-c, which UE 115-c can use to monitor a set of control information resources for control information assigned to the EU 115-c. In some cases, base station 105-c explicitly indicates a transmit beam direction for UE 115-c to monitor in a control information transmission cluster. In other cases, base station 105-c can transmit a bitmap to UE 115-
[00141] [00141] In step 625, the UE 115-c can indicate a delay associated with the tuning of a receiver from the first bandwidth to the second bandwidth ("tuning delay") to the base station 105-b. In some cases, the UE 115-c may indicate the re-tuning delay based on the determination that a narrowband control channel width is being used by the base station 105-b.
[00142] [00142] In step 630, UE 115-c can indicate a preferred beam to base station 105-b. In some examples, UE 115-c identifies a preferred beam based on previously transmitted SS blocks or CSI-RS signals subjected to beam formation. UE 115-c can also indicate a scheduling capability between slots or between symbols. Base station 105-c can apply scheduling between symbols or between slots based on the indicated capacity.
[00143] [00143] In step 635, base station 105-b can receive data or control layer signaling for one or more UEs, including UE 115-c. In some examples, base station 105-b can receive user data for UE 115-c and can schedule a paging request for UE 115-c using a control information grouping scheme. In other examples, base station 105-b can generate system information for UE 115-c and can schedule a MIB or SIB message for UE 115-c and other UEs using a control information grouping scheme. In other cases, base station 105-b can receive user data for UE 115-c, and can schedule UE 115-c using a control information grouping scheme.
[00144] [00144] In step 640, base station 105-can schedule data and control transmissions to the UEs. In some cases, base station 105-b can schedule data and control transmissions according to the control information cluster transmission scheme. For example, base station 105-b can schedule data and control transmissions to UE 115-c so that a time difference between transmitting control information and data transmissions is at least as long as an interval of re-tuning.
[00145] [00145] In step 645, base station 105-b can transmit control information to the UEs. In some cases, base station 105-b may transmit control information to UEs through consecutive control channel resource sets in a control information transmission cluster, similar to the configuration of channel resource sets control panel in Figure 4. In some cases, base station 105-b can transmit control information in a beam-scanned pattern. For example, base station 105-b can transmit the first control information to UE 115-c via a first set of control channel resources in a first direction, the second control information to a second UE via of a second set of control channel features in a second direction, and so on. In some cases, base station 105-b can transmit the first control information in the first one or more symbol periods of a transmission slot, the second control information in the next one or more symbol periods of the transmission slot and so on. In some cases, base station 105-b may include control information for UE 115-c in a transmission slot symbol period that corresponds to a preferred beam direction of UE 115-c. For example, base station 105-b can transmit control information to UE 115-c in the first two symbol periods and in the first beam direction.
[00146] [00146] Also in step 645, UE 115-c can monitor a set of control channel resources for a transmission of control information from base station 105-b. During monitoring, UE 115-c can receive control information transmitted by base station 105- b on a set of control channel resources identified by UE 115-c, and can blindly decode control information based on the indicated monitoring standard. In some instances, a UE may apply an assumption of quasi-co-location between SS blocks and a set of PDCCH occasions that the UE monitors. For example, the identified control channel feature set can be associated with a first beam direction and correlated symbol periods. Therefore, the UE 115-c can monitor its preferred beam direction or a beam direction designated by base station 105-b for control information. Additionally or alternatively, the UE 115-c can monitor the first two symbol periods of a slot that contains control information. The UE
[00147] [00147] In step 650, UE 115-c can identify data resources that are scheduled for data transmission to UE 115-c. In some cases, the UE 115-c identifies a location of the data resources based on the received control information. For example, control information may indicate to the UE 115-c that frequency resources in designated symbol periods are allocated for a downlink transmission to the UE 115-c.
[00148] [00148] In step 655, the UE 115-c can re-tune its receiver to be configured to receive data over a different bandwidth (for example, a wide bandwidth) than the bandwidth used to receive information from control. As discussed above, re-tuning a receiver can take a certain amount of time that is in the range of one symbol period to multiple symbol periods (for example, up to 10 symbol periods).
[00149] [00149] In step 660, the base station 105-b can transmit data to UE 115-c in the data resources scheduled after a re-tuning interval expires as the transmission of control information to UE 115-c. Also in step 660, the UE 115-c can receive data transmission via the broadband frequency.
[00150] [00150] Figure 7 shows a block diagram
[00151] [00151] The 710 receiver can receive information such as packages, user data, or control information associated with various information channels (for example, control channels, data channels and information related to data multiplexing and grouped control information, etc.). The information can be passed on to the other components of the device. Receiver 710 can be an example of aspects of transceiver 935 described with reference to Figure 9. Receiver 710 can use a single antenna or a set of antennas.
[00152] [00152] The base station control information manager 715 can be an example of aspects of the base station control information manager 915 described with reference to Figure 9.
[00153] [00153] The base station control information manager 715 and / or at least some of its several - can be deployed in hardware, software run by a processor, firmware, or any combination thereof. If deployed in software run by a processor, the functions of the 715 base station control information manager and / or at least some of its various subcomponents can be performed by a general purpose processor, a digital signal processor (DSP) , an application-specific integrated circuit (ASIC), a field programmable gate array (FPGA) or other programmable logic device, discrete gate or transistor logic, discrete hardware components, or any combination of them designed to perform the functions described in the present revelation. The base station control information manager 715 and / or at least some of its various subcomponents can be physically located in various positions, including being distributed so that portions of functions are deployed in different physical locations by one or more devices physicists. In some instances, the base station control information manager 715 and / or at least some of its various subcomponents may be a separate and separate component according to various aspects of the present disclosure. In other examples, the base station control information manager 715 and / or at least some of its various subcomponents can be combined with one or more other hardware components, including, without limitation, an I / O component, a transceiver, a network server, another computing device, one or more other components described in the present disclosure, or a combination thereof according to various aspects of the present disclosure.
[00154] [00154] The base station control information manager 715 can transmit an indication of which of a grouped scheme or a distributed scheme is configured for transmitting control information, transmitting, during first time resources, the first control information that schedule a first data transmission for second time resources, with the first time resources being selected based on the indication. The base station control information manager 715 can also transmit, during third time resources, second control information that schedule a second data transmission during fourth time resources, the third time resources being selected based on the recommendation. Base station control information manager 715 can also transmit the first data transmission during the second time resources and transmit the second data transmission during the fourth time resources.
[00155] [00155] The base station control information manager 715 can identify, for a first server user equipment (UE) by the base station, a first delay associated with the resynchronization of a receiving bandwidth from a receiver of the first HUH. The base station control information manager 715 can also identify, for a second UE served by the base station, a second delay associated with the re-tuning of a receiving bandwidth from a second UE receiver. Base station control information manager 715 can transmit, during first time resources through a first frequency bandwidth, a first downlink lease that schedules a first data transmission to the first UE for second resources of time by means of a second frequency bandwidth, the second time resources being selected based on the first time resources and the first delay. Base station control information manager 715 can also transmit, during third time resources through a third frequency bandwidth, a second downlink lease that schedules a second data transmission to the second UE over quarters time resources through a fourth frequency bandwidth, with the fourth time resources being selected based on the third time resources and the second delay. The base station control information manager 715 can also transmit the first data transmission during the fourth seconds of time via the second frequency bandwidth. A base station control information manager 715 can also transmit the second data transmission during the fourth time resources via the second frequency bandwidth.
[00156] [00156] The transmitter 720 can transmit signals generated by other components of the device. In some examples, transmitter 720 can be placed with a receiver 710 in a transceiver module. For example, transmitter 720 can be an example of aspects of transceiver 935 described with reference to Figure 9. Transmitter 720 can use a single antenna or a set of antennas.
[00157] [00157] Figure 8 shows a block diagram
[00158] [00158] The 810 receiver can receive information such as packages, user data, or control information associated with various information channels (for example, control channels, data channels and information related to data multiplexing and grouped control information, etc.). The information can be passed on to the other components of the device. The receiver 810 can be an example of aspects of the transceiver 935 described with reference to Figure 9. The receiver 810 can use a single antenna or a set of antennas.
[00159] [00159] The base station control information manager 815 can be an example of aspects of the base station control information manager 915 described with reference to Figure 9. The base station control information manager 815 also it can include the control information scheduler 825, the control transmission manager 830 and the data transmission manager 835.
[00160] [00160] The control information scheduler
[00161] [00161] The control information scheduler 825 can identify, for a first UE served by the base station, a first delay associated with the re-tuning of a receiving bandwidth from a receiver of the first UE. The control information scheduler 825 can also identify, for a second UE served by the base station, a second delay associated with the re-tuning of a receiving bandwidth from a second UE receiver. In some cases, the 825 control information scheduler can transmit an indication that control information transmissions are configured in a control information transmission grouping. The control information scheduler 825 can also transmit a mapping pattern between a beam pattern corresponding to the reference signal or synchronization signal transmissions and a control information beam pattern of the control information transmission cluster. The control information scheduler 825 can also indicate a monitoring standard for the grouping of transmission of control information to the first UE or the second UE. The control information scheduler 825 can also receive, from the first UE, a first indication of the first delay, and receive from the second UE, a second indication of the second delay. In some instances, control information scheduler 825 may determine that the first delay is greater than the second delay, and schedule the transmission of the first downlink lease before the transmission of the second downlink lease based on the determination. In some cases, the second time resources are after the first time resources and the fourth time resources are before the third time resources.
[00162] [00162] The control transmission manager 830 can transmit, during first time resources, first control information that schedule a first data transmission during second time resources, the first time resources being selected based on the indication and transmit, during third time resources, second control information that schedule a second data transmission during fourth time resources, the third time resources being selected based on the indication. The control transmission manager 830 transmits first control information and second control information in a control information transmission grouping based on the transmission of an indication that the grouped scheme is configured for control information transmissions. When a grouped transmission scheme is configured, the second time resources and the fourth time resources can occur after the first time resources and the third time resources. When a distributed transmission scheme is set up, the second time resources can occur after the first time resources, the third time resources can occur after the second time resources, and the fourth time resources can occur after the third time resources. time. In some cases, the first frequency bandwidth is less than the second frequency bandwidth and the third frequency bandwidth is less than the fourth frequency bandwidth. In some cases, the first frequency bandwidth is the same size as the second frequency bandwidth and the third frequency bandwidth is the same size as the fourth frequency bandwidth.
[00163] [00163] The control transmission manager 830 can transmit, during first time resources by means of a first frequency bandwidth, a first downlink concession that schedules a first data transmission to the first UE during second resources of time through a second frequency bandwidth, the second time resources being selected based on the first time resources and the first delay. The control transmission manager 830 can also transmit, during third time resources through a third frequency bandwidth, a second downlink concession that schedules a second data transmission to the second UE during fourth time resources for through a fourth frequency bandwidth, with the fourth time resources being selected based on the third time resources and the second delay.
[00164] [00164] In some cases, the first data transmission or the second data transmission includes a system information block (SIB) message, a random access response message, a paging message, or a data block of user. In some cases, the first downlink lease is transmitted in a first beam direction and the second downlink lease is transmitted in a second beam direction. In some cases, the first frequency bandwidth is less than the second frequency bandwidth. In some cases, the first frequency bandwidth overlaps in frequency with the second frequency bandwidth. In some cases, the first frequency bandwidth and the third frequency bandwidth are the same. In some cases, the first frequency bandwidth and the third frequency bandwidth are different. In some cases, the second frequency bandwidth and the fourth frequency bandwidth are the same. In some cases, the second frequency bandwidth and the fourth frequency bandwidth are different. In some cases, the first frequency bandwidth is not overlapped in frequency with the second frequency bandwidth.
[00165] [00165] The data transmission manager 835 can transmit the first data transmission during the second time resources. In some cases, the first data can be transmitted via the second frequency bandwidth. The data transmission manager 835 can transmit the second data transmission during the fourth time resources. In some cases, the second data can be transmitted via the second frequency bandwidth or a fourth frequency bandwidth.
[00166] [00166] The transmitter 820 can transmit signals generated by other components of the device. In some examples, transmitter 820 can be placed with a receiver 810 in a transceiver module. For example, transmitter 820 can be an example of aspects of transceiver 935 described with reference to Figure 9. Transmitter 820 can use a single antenna or a set of antennas.

The UEs described in this document may have the ability to communicate with various types of base stations and network equipment including macro eNBs, small cell eNBs, gNBs, relay base stations and the like. There may be overlapping geographic coverage areas for different technologies.
[00226] [00226] A macrocell generally covers a relatively large geographical area (for example, several kilometers in radius) and can allow unrestricted access by UEs with service subscriptions with the network provider. The small cell is a base station with less power compared to a macrocell, which can operate in the same or different frequency bands (for example, licensed, unlicensed, etc.) as the macrocells. Small cells can include picocells, femtocells and microcells according to several examples. A picocell, for example, can cover a small geographical area and can allow unrestricted access by UEs with service subscriptions with the network provider. A femtocell can also cover a small geographical area (for example, a residence) and, in addition to unrestricted access, it could also provide restricted access for UEs that have an association with a femtocell (for example, UEs in a closed subscriber group ( CSG), UEs for home users and the like). An eNB for a macrocell can be called an eNB macro. An eNB for a small cell can be called a small cell eNB, an eNB peak, an eNB femto, or a domestic eNB. An eNB can support one or multiple (for example, two, three, four and the like) cells (for example, component carriers).
[00227] [00227] The wireless communication system or systems described in this document may support synchronous or asynchronous operation. For synchronous operation, base stations may have a similar frame delay, and transmissions from different base stations may be approximately time aligned. For asynchronous operation, base stations may have a different frame delay, and transmissions from different base stations may not be time aligned. The techniques in this document can be used for both synchronous and asynchronous operations.
[00228] [00228] The downlink transmissions described in this document can also be called progressive link transmissions while the uplink transmissions can also be called reverse link transmissions. Each communication link described herein that includes, for example, wireless communications system 100 and wireless communications subsystem 200 of Figures 1 and 2 can include one or more carriers, each carrier being a signal composed of multiple subcarriers (for example, waveform signals of different frequencies).
[00229] [00229] The description presented in this document in connection with the attached drawings describes exemplary configurations and does not represent all examples that can be implemented or that are covered by the scope of the claims. The term "exemplary" used in this document means "serving as an example, instance, or illustration", not "preferred" or "advantageous over other examples". The detailed description includes specific details for the purpose of providing an understanding of the techniques described. These techniques can, however, be practiced without these specific details. In some examples, well-known structures and devices are shown in the form of a block diagram in order to avoid obscuring the concepts of the examples described.
[00230] [00230] In the attached figures, components or similar resources may have the same reference mark. In addition, several components of the same type can be distinguished by following the reference mark through a dash and a second mark that distinguishes among similar components. If only a first benchmark is used in the specification, the description is applicable to any of the similar components that have the same first benchmark, regardless of the second benchmark.
[00231] [00231] The information and signals described in this document can be represented using any one of a variety of different technologies and techniques. For example, data, instructions, commands, information, signals, bits, symbols and chips that can be referenced throughout the above description can be represented by voltages, currents, electromagnetic waves, particles or magnetic fields, particles or optical fields or any combination of the same.
[00232] [00232] The various blocks and illustrative modules described in connection with the disclosure in this document can be deployed or performed with a general purpose processor, DSP, ASIC, FPGA or other programmable logic device, discrete gate or transistor logic , discrete hardware components or any combination thereof designed to perform the functions described in this document. A general purpose processor can be a microprocessor, but, alternatively, the processor can be any processor, controller, microcontroller or conventional state machine. A processor can also be deployed as a combination of computing devices (for example, a combination of a DSP and a microprocessor, multiple microprocessors, one or more microprocessors in combination with a DSP core or any other such configuration).
[00233] [00233] The functions described in this document can be implemented in hardware, software executed by a processor, firmware, or any combination thereof. If implemented in software run by a processor, the functions can be stored on, or transmitted by, as one or more instructions or code, a computer-readable medium. Other examples and deployments are covered by the scope of the disclosure and the attached claims. For example, due to the nature of the software, the functions described above can be implemented using software executed by a processor, hardware, firmware, wired connection or combinations of any of these. The implantation functions of particularities can also be physically located in various positions, which includes being distributed so that portions of the functions are implanted in different physical locations. In addition, as used herein, including in claims, "or" as used in a list of items (for example, a list of items preceded by a phrase such as "at least one of" or "one or more of" ), indicates an inclusive list so that, for example, a list of at least one of A, B or C means A or B or C or AB or AC or BC or ABC (that is, A and B and C). In addition, as used in this document, the phrase "based on" should not be interpreted as a reference to a closed set of conditions. For example, an exemplary step that is described as "based on condition A" can be based on either condition A or condition B without departing from the scope of the present disclosure. In other words, as used herein, the phrase "based on" will be interpreted in the same way as the phrase "based, at least in part, on".
[00234] [00234] Computer-readable media includes both non-transitory computer storage media and communication media, including any media that facilitates the transfer of a computer program from one location to another. A non-transitory storage medium can be any available medium that can be accessed by a general purpose or a specific purpose computer. For example, and not by way of limitation, non-transitory computer-readable media may comprise RAM, ROM, electrically programmable and erasable read-only memory (EEPROM), compact disc (CD) -ROM or other optical disc storage, storage magnetic disk or other magnetic storage devices or any other non-transitory media that can be used to port or store desired program code media in the form of instructions or data structures and that can be accessed by a general purpose computer or specific purpose or a general purpose or specific purpose processor. In addition, any connection is properly designated as computer-readable media. For example, if the software is transmitted from a website, server or other remote source using a coaxial cable, fiber optic cable, twisted pair, digital subscriber line (DSL) or wireless technologies, such as infrared, radio and microwave, then coaxial cable, fiber optic cable, twisted pair, DSL or wireless technologies such as infrared, radio and microwave are included in the definition of medium. Magnetic disk and optical disk, as used in this document, include CD, laser disk, optical disk, digital versatile disk (DVD), floppy disk and Blu-ray disk, where magnetic disks frequently reproduce data in a magnetic way, while optical discs reproduce data optically with lasers. Combinations of the above are also included in the scope of computer-readable media.
[00235] [00235] The description in this document is provided to enable a person skilled in the art to produce or use the disclosure. Several changes in such modalities will be readily apparent to those skilled in the art and the generic principles defined in this document can be applied to other variations without departing from the scope of the disclosure. Therefore, the disclosure is not limited to the examples and projects described in this document, but must be in accordance with the broadest scope consistent with the principles and innovative features revealed in this document.
