CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application claims the priority and benefit of the provisional application η ^Ω of US series 62 / 417,789, filed with the US Patent and Trademark Office on November 4, 2016, and the non-provisional application η ^Ω US 15 / 710,771, filed with the US Patent and Trademark Office on September 20, 2016, the entire contents of which are incorporated herein by reference as if fully set forth below in their entirety and for all applicable purposes.
FIELD OF TECHNIQUE [0002] The technology discussed below refers in general to wireless communication systems and, more particularly, to reconfigurable uplink control transmissions for wireless communication and communication methods.
INTRODUCTION [0003] Wireless communication systems are widely deployed to provide various telecommunication services, such as telephony, video, data, messages and broadcasts. Typical wireless communication systems can employ multiple access technologies with the ability to support communication with multiple users by sharing available system resources (for example,
example, width band, power of streaming). The examples in such technologies access multiple include systems in access the multiple per division of code (CDMA), systems in access the multiple per division of time (TDMA),
Petition 870190041063, of 5/2/2019, p. 7/98
2/61 Frequency Division Multiple Access Systems (FDMA), Orthogonal Frequency Division Multiple Access Systems (OFDMA), Single Carrier Frequency Division Multiple Access Systems (SC-FDMA).
[0004] Multiple access technologies have been adopted in several telecommunication standards to provide a common protocol that allows different wireless devices to communicate at a municipal, national, regional and even global level. For example, the fifth generation (5G) Novo Rádio (NR) communications technology is expected to expand and support various usage scenarios and applications in relation to the generations of current mobile networks. In one aspect, 5G communications technology includes advanced mobile broadband addresses human-centered use cases for access to multimedia content, services and data; ultra-reliable low-latency communications (URLLC) with strict requirements, especially in terms of latency and reliability; and massive machine-type communications for a very large number of connected devices and typically transmitting a relatively low volume of non-delay-sensitive information.
[0005] Wireless communication networks are being used to provide and support an even wider range of services for various types of devices with different capacities. Although some devices may fully utilize the available bandwidth of the communication channels, some devices have limited capacity or less capacity to use the full bandwidth and / or need to save energy

3/61 to extend operating time, especially for battery powered devices. However, in current communication standards, such as Long Term Evolution (LTE), certain aspects of the downlink partition structure can limit the extent of energy savings and spectral efficiency, especially if extended to a bandwidth implementation. wider range of next generation networks or 5G networks.
[0006] However, as the demand for mobile broadband access continues to increase, there is a need for further improvements in 5G communications technology and beyond. Preferably, these enhancements should apply to other multiple access technologies and the telecommunication standards that employ those technologies.

The detailed description includes specific details for the purpose of providing a complete understanding of various concepts. However, it will be evident to those skilled in the art that these concepts can be practiced without these specific details. In some cases, well-known structures and components are shown in the form of a block diagram in order to avoid obscuring such concepts.
[0026] Aspects of the present revelation
provide feedback in UL control flexible and reconfigurable that can to be used in nets in wireless communication 5G or in next generation , including
networks that implement NR communications technology. Feedback related to DL transmissions can be provided in short UL bursts within the partitions carrying UL transmissions. In some cases,

9/61 processing, power reserve and other operating conditions can cause a base station to program the feedback transmission associated with a first partition on a second partition. In some cases, charging or network interference associated with certain types of UL bursts can cause the feedback to be transmitted in other UL bursts.
[0027] The various concepts presented throughout this disclosure can be implemented through a wide variety of telecommunication systems, network architectures and communication standards. Now, with reference to Figure 1, as an illustrative example, without limitation, a schematic illustration of a radio access network 100 is provided.
[0028] The geographical region covered by the radio access network 100 can be divided into several cellular regions (cells) that can be uniquely identified by a user device (UE) based on an identification spread across a geographical area from an access point or base station. Figure 1 illustrates macrocells 102, 104 and 106, and a small cell 108, each of which may include one or more sectors. A sector is a sub-area of a cell. All sectors within a cell are served by the same base station. A radio link within a sector can be identified by a unique identification that belongs to that sector. In a cell that is divided into sectors, the multiple sectors within a cell can be formed by groups of antennas, with each antenna responsible for communicating with UEs in a portion of the cell.
Petition 870190041063, of 5/2/2019, p. 15/98
10/61 [0029] In general, a base station (BS) serves each cell. Broadly speaking, a base station is a network element in a radio access network responsible for radio transmission and reception in one or more cells to or from a UE. A BS can also be called, by those skilled in the art, as a transceiver base station (BTS), a radio base station, a radio transceiver, a transceiver function, a set of basic services (BSS), a set extended services (ESS), an access point (AP), a Node B (NB), an eNode B (eNB), a gNode B (gNB) or some other suitable terminology.
[0030] In Figure 1, two high power base stations 110 and 112 are shown in cells 102 and 104; and a third high power base station 114 is shown controlling a remote radio head (RRH) 116 in cell 106. That is, a base station can have an integrated antenna or can be connected to an antenna or RRH by power cables . In the illustrated example, cells 102, 104 and 106 can be called macrocells, as the high power base stations 110, 112 and 114 support cells that are large in size. In addition, a low power base station 118 is shown in small cell 108 (for example, a microcell, picocell, femtocell, initial base station, initial Node B, initial eNode B, etc.) that can overlap one or more macrocells . In this example, cell 108 can be called a small cell, as the low power base station 118 supports a cell that is relatively small in size. Cell sizing can be done
Petition 870190041063, of 5/2/2019, p. 16/98
11/61 according to the system design, as well as component restrictions. It should be understood that the radio access network 100 can include any number of wireless base stations and cells. In addition, a retransmission node can be installed to extend the size or area of coverage in a given cell. Base stations 110, 112, 114, 118 provide wireless access points for a core network to any number of mobile devices.
[0031] Figure 1 additionally includes a quadcopter or drone 120, which can be configured to function as a base station. That is, in some instances, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a mobile base station, such as quadcopter 120.
[0032] In general, base stations can include a backhaul interface for communication with a backhaul portion of the network. The backhaul can provide a link between a base station and a main network, and in some instances, the backhaul can provide interconnection between the respective base stations. The main network is part of a wireless communication system that is generally independent of the radio access technology used in the radio access network. Various types of backhaul interfaces can be used, such as a direct physical connection, a virtual network, or the like, with the use of any suitable transport network. Some base stations can be configured as integrated access and backhaul (IAB) nodes, where the wireless spectrum can be used for both access links (ie, wireless links with
Petition 870190041063, of 5/2/2019, p. 17/98
12/61
UEs) as for backhaul links. This scheme is sometimes called wireless auto-backhaul. When using wireless autobackhaul, instead of requiring each new base station deployment to be equipped with its own wired-wireless backhaul connection, the wireless spectrum is used for communication between the base station and the UE can be be harnessed for backhaul communication, allowing quick and easy deployment of small dense cell networks.
[0033] The radio access network 100 is illustrated supporting wireless communication for multiple mobile devices. A mobile device is commonly called a user equipment (UE) standards and specifications promulgated by the 3rd generation partnership project (3GPP)
but also can to be called by those knowledgeable at technical, an mobile station (MS), an season in subscriber, a unit mobile, one unit subscriber, an
wireless unit, a remote unit, a mobile device, a wireless device, a wireless communications device, a remote device, a mobile subscriber station, an access terminal (AT), a mobile terminal, a wireless terminal , a remote terminal, a handset, a user agent, a mobile client, a client or some other suitable terminology. An UE can be a device that endows a user with access to network services.
[0034] In the present document, a mobile device does not necessarily have to be able to move, and can be stationary. The term mobile device or mobile device refers widely to a diverse set of devices and technologies. For example,
Petition 870190041063, of 5/2/2019, p. 18/98
13/61 some non-limiting examples of a mobile device include a mobile phone, a cell phone (cell), a smart phone, a session initiation protocol (SIP) phone, a laptop computer, a personal computer (PC ), a notebook computer, a netbook, a smartbook, a tablet computer, a personal digital assistant (PDA) and a wide range of embedded systems, for example, corresponding to an Internet of Things (loT). A mobile device can additionally be an automotive vehicle or other transportation vehicle, a remote sensor or actuator, a robot or robotics device, a satellite radio, a global positioning system (GPS) device, an object tracking device, a drone, multicopter, quadcopter, remote control device, consumer device and / or body-worn device, such as glasses, a body-worn camera, a virtual reality device, a smart wristwatch, a health or fitness tracker, a digital audio player (for example, MP3 player), a camera, a game console, etc. A mobile device can additionally be a digital home or smart home device, such as a home audio, video and / or multimedia device, an appliance, a vending machine, smart lighting, a home security system, a smart meter, etc. A mobile device can additionally be an intelligent energy device, a security device, a solar panel or solar array, a municipal infrastructure device that controls electricity (for example, a
Petition 870190041063, of 5/2/2019, p. 19/98
14/61 smart grid), light, water, etc .; a business and industrial automation device; a logistics controller; agricultural equipment; military defense equipment, vehicles, aircraft, ships and armaments, etc. Furthermore, a mobile device can provide support for connected medicine or telemedicine, that is, healthcare at a distance. Telehealth devices may include telehealth monitoring devices and telehealth management devices, the communication of which may receive preferential treatment or prioritized access to other types of information, for example, in terms of prioritized access to data transport.
service critics and / or QoS relevant for transport in data from service critics.[0035] At network access per radio 100, at cells may include UEs that may be in communication with one or more sectors each cell. Per example, UEs 122 and 124 may be in Communication with the base station 110; the UEs 126 and 128 may be in i Communication with
base station 112; UEs 130 and 132 may be in communication with base station 114 via RRH 116; the UE 134 may be in communication with the low power base station 118; and UE 136 can be in communication with mobile base station 120. Here, each base station 110, 112, 114, 118 and 120 can be configured to provide an access point for a main network (not shown) for everyone the UEs in their cells. Transmissions from a base station (for example, base station 110) to one or more UEs (for example, UEs 122 and 124) can be called downlink transmission (DL),
Petition 870190041063, of 5/2/2019, p. 20/98
15/61 while transmissions from a UE (e.g., UE 122) to a base station can be called uplink (UL) transmissions. According to certain aspects of the present disclosure, the term downlink can refer to a point-to-multipoint transmission that originates in a 202 programming entity. Another means of describing this scheme may be the use of the term diffusion channel multiplexing. According to additional aspects of the present disclosure, the term uplink can refer to a point-to-point transmission that originates in a programmed entity 204.
[0036] In some examples, a mobile network node (for example, quadcopter 120) can be configured to function as a UE. For example, quadcopter 120 can operate within cell 102 when communicating with base station 110. In some aspects of the disclosure, two or more UEs (for example, UEs 126 and 128) can communicate with each other using point-to-point signals ( P2P) or side link 127 without relaying this communication via a base station (for example, base station 112).
[0037] In the radio access network 100, the ability for a UE to communicate while moving, regardless of its location, is called mobility. The various physical channels between the UE and the radio access network are generally configured, maintained and released under the control of a mobility management entity (MME). In several aspects of the disclosure, a radio access network 100 can use DL-based mobility or UL-based mobility to allow mobility and handovers (that is, the transfer of a
Petition 870190041063, of 5/2/2019, p. 21/98
16/61 UE connection from one radio channel to another). In a network configured for DL-based mobility, during a call with a programming entity, or at any other time, a UE can monitor various signal parameters from its server cell, as well as several neighboring cell parameters. Depending on the quality of these parameters, the UE can maintain communication with one or more of the neighboring cells. During that time, if the UE moves from one cell to another, or if a signal quality from a neighboring cell exceeds that of the serving cell for a certain period of time, the UE can perform a handoff or handover from the serving cell. to the neighboring (target) cell. For example, UE 124 (illustrated as a vehicle, although any suitable form of UE can be used) can move from the geographical area that corresponds to its serving cell 102 to the geographical area that corresponds to a neighboring cell 106. When the signal strength or quality from the neighboring cell 106 exceeds that of its server cell 102 for a given period of time, the UE 124 can transmit a report message to its server base station 110 indicating this condition. In response, UE 124 may receive a handover command, and the UE may be handovered to cell 106.
[0038] In a network configured for UL-based mobility, UL reference signals from each UE can be used by the network to select a server cell for each UE. In some examples, base stations 110, 112, and 114/116 may broadcast unified sync signals (for example,
Petition 870190041063, of 5/2/2019, p. 22/98
17/61
Unified Primary Synchronization (PS Ss), Unified Secondary Synchronization Signals (SSSs) and Unified Physical Broadcast Channels (PBCH)). UEs 122, 124, 126, 128, 130 and 132 can receive the unified sync signals, derive the carrier frequency and partition timing from the sync signals, and, in response to the timing derivation, transmit a pilot signal or uplink reference. The uplink pilot signal transmitted by a UE (for example, UE 124) can be simultaneously received by two or more cells (for example, base stations 110 and 114/116) within the radio access network 100. Each of the cells can measure a pilot signal strength, and the radio access network (for example, one or more of the base stations 110 and 114/116 and / or a central node within the main network) can determine a serving cell for the UE 124. As the UE 124 moves through the radio access network 100, the network can continue to monitor the uplink pilot signal transmitted by the UE 124. When the signal strength or quality of the pilot signal measured by a cell neighbor exceeds that of the signal strength or quality measured by the server cell, the network 100 can handover the UE 124 from the server cell to the neighbor cell, with or without informing the UE 124.
[0039] Although the synchronization signal transmitted by base stations 110, 112 and 114/116 can be unified, the synchronization signal may not identify a particular cell, but instead it can identify a zone of multiple cells operating in the
Petition 870190041063, of 5/2/2019, p. 23/98
18/61 same frequency and / or with the same timing. The use of zones in 5G networks or other next generation communication networks allows the uplink based mobility structure and improves the efficiency of both the UE and the network, since the number of mobility messages that need to be exchanged between the EU and the network can be reduced.
[0040] In several implementations, the air interface in the radio access network 100 can use licensed spectrum, unlicensed spectrum or shared spectrum. The licensed spectrum provides exclusive use of a portion of the spectrum, usually by virtue of a mobile network operator that acquires a license from a government regulator. Unlicensed spectrum provides shared use of a portion of the spectrum without the need for a government-issued license. Although compliance with some technical rules is still generally required to access the unlicensed spectrum, generally, any operator or device can gain access. The shared spectrum can be located between the licensed and unlicensed spectrum, where technical rules or limitations may be required to access the spectrum, however the spectrum can still be shared by multiple operators and / or multiple RATs. For example, a license holder for a portion of the licensed spectrum may provide licensed shared access (LSA) to share that spectrum with third parties, for example, under conditions determined by the licensee appropriate to obtain access.
[0041] In some examples, access to
Petition 870190041063, of 5/2/2019, p. 24/98
19/61 air interface can be programmed, in which a programming entity (for example, a base station) allocates resources for communication between some or all devices and equipment within its area or service cell. In the present disclosure, as further discussed below, the programming entity may be responsible for programming, assigning, reconfiguring and releasing resources for one or more programmed entities. That is, for programmed communication, UEs or programmed entities use resources allocated by the programming entity.
[0042]
Base stations are not the only entities that can function as a programming entity. That is, in some examples, a UE can function as a programming entity by programming resources for one or more programmed entities (for example, one or more other UEs). In other examples, side link signals can be used between UEs without necessarily relying on programming or control information from a base station. For example, UE 138 is illustrated communicating with UEs 140 and 142. In some examples, UE 138 is functioning as a programming entity or a primary side link device, and UEs 140 and 142 can function as an entity programmed or a non-primary side link device (for example, secondary). In yet another example, a UE can function as a programming entity on a device to device (D2D), P2P or vehicle to vehicle (V2V) network and / or on a mesh network. In an example of a mesh network, UEs 140 and 42 can optionally communicate directly with each other in addition to communicating with UE 138.
Petition 870190041063, of 5/2/2019, p. 25/98
20/61 [0043] Thus, in a wireless communication network with programmed access to temp frequency resources and that has a cellular configuration, a P2P configuration or a mesh configuration, a programming entity and one or more programmed entities can communicate using the programmed resources. Now, with reference to Figure 2, a block diagram 200 illustrates a programming entity 202 and a plurality of programmed entities 204 (for example, 204a and 204b). Here, programming entity 202 can correspond to base stations 110, 112, 114 and / or 118. In additional examples, programming entity 202 can correspond to UE 138, quadcopter 120 or any other suitable node on the network radio access number 100. Similarly, in several examples, programmed entity 204 may correspond to UE 122, 124, 126, 128, 130, 132, 134, 136, 138, 140 and 142, or any other suitable node in radio access network 100.
[0044] As illustrated in Figure 2, the programming entity 202 can transmit or broadcast traffic 206 and / or control 208 to one or more programmed entities 204 (the traffic can be called downlink traffic). Broadly speaking, programming entity 202 is a node or device responsible for scheduling traffic on a wireless communication network, including downlink transmissions and, in some examples, uplink traffic 210 and / or link control ascending 212 from one or more entities programmed for programming entity 202. Broadly, programmed entity 204 is a node or
Petition 870190041063, of 5/2/2019, p. 26/98
21/61 device that receives control information, including, but not limited to, programming information (for example, a lease), synchronization or timing information, or other control information from another entity on the wireless communication network, such as programming entity 202.
[0045] In some examples, programmed entities, such as a first programmed entity 204a and a second programmed entity 204b can use side link signals for direct D2D communication. Side link signals may include side link traffic 214 and side link control 216. Side link control information 216 may, in some instances, include a request signal, such as a request for sending (RTS), a source transmission signal (STS) and / or a direction selection signal (DSS). The request signal can provide a programmed entity 204 to request a length of time to request a length of time to maintain a side link channel available for a side link signal. The side link control information 216 may additionally include a response signal, such as a send-forward (CTS) and / or a destination receive signal (DRS). The response signal can provide programmed entity 204 to indicate the availability of the side link channel, for example, for a requested length of time. An exchange of request and response signals (for example, handshake) can allow different programmed entities that perform side link communications to negotiate the availability of the link channel
Petition 870190041063, of 5/2/2019, p. 27/98
22/61 side before the communication of side link traffic information 214.
[0046] The air interface on the radio access network 100 may use one or more duplexing algorithms. Duplex refers to a point-to-point communication link where both endpoints can communicate with each other in both directions. Full duplex means that both endpoints can communicate with each other simultaneously. Half duplex means that only one endpoint can send information to the other at a time. In a wireless link, a full duplex channel generally depends on physical isolation from a transmitter or receiver, and adequate interference cancellation technologies. Full duplex emulation is often implemented for wireless links using frequency division duplexing (FDD) or time division duplexing (TDD). In FDD, transmissions in different directions operate on different carrier frequencies. In TDD, transmissions in different directions on a given channel are separated from each other using time division multiplexing. That is, at times, the channel is dedicated to transmissions in one direction, while at other times, the channel is dedicated to transmissions in the other direction, where the direction can change very quickly, for example, several times per partition.
[0047] Transmissions over the radio access network 100 can generally use an appropriate error correction block code. In a typical block code, a message or sequence of information is divided

23/61 in code blocks (CBs), and an encoder (for example, a CODEC) in the transmission device, then mathematically adds redundancy to the information message. The exploitation of this redundancy in the coded information message can improve the reliability of the message, allowing the correction for any bit errors that may occur due to noise. Some examples of error correction codes include Hamming codes, BoseChaudhuri-Hocquenghem (BCH) codes, Turbo codes, low density parity verification codes (LDPC) and Polar codes. Various implementations of programming entities 202 and programmed entities 204 may include suitable hardware and capabilities (for example, an encoder, a decoder and / or a CODEC) to use any one or more of these error correction codes for wireless communication.
[0048] The aerial interface in the radio access network 100 can use one or more multiplexing and multiple access algorithms to allow simultaneous communication of the various devices. For example, multiple access for uplink (UL) or reverse link transmissions from UEs 122 and 124 to base station 110 can be provided using time division multiple access (TDMA), code division multiple access (CDMA) ), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), discrete Fourier transform spread (DFT) or single carrier FDMA (DFT-sOFDMA or SC-FDMA), sparse code multiple access (SCMA), resource spread multiple access (RSMA)

24/61 or other suitable multiple access schemes. In addition, multiplexing of downlink (DL) or direct link transmissions from base station 110 to UEs 122 and 124 can be provided using time division multiplexing (TDM), code division multiplexing (CDM), frequency division multiplexing (FDM), orthogonal frequency division multiplexing (OFDM), sparse code multiplexing (SCM) other suitable multiplexing schemes.
[0049] Figure 3 illustrates an example of partitions in an access network that uses a TDD carrier. Communication can be organized by dividing the channel in the time domain into frames, and the frames are further divided into partitions. According to one aspect of the present disclosure, partitions can take at least two general forms, referred to in this document as a partition structure centered on UL 302 and a partition structure centered on DL 304. Here, a partition centered on DL is a partition where most of its programmed time is used for communication in the downlink direction (for example, shown as a DL 306 burst in Figure 3); and a UL-centered partition is a partition where most of its programmed time is used for uplink communication (for example, shown as a UL 308 burst in Figure 3).
[0050] In a typical cell deployment, there may be an asymmetry between downlink traffic and uplink traffic. In general, a network can communicate a greater amount of downlink traffic and, consequently, a greater number of
Petition 870190041063, of 5/2/2019, p. 30/98
25/61 DL-centered partitions can be programmed. In addition, even though this imbalance may be predictable, the actual ratio between UL-centered partitions and DL-centered partitions may not be predictable, and may vary over time. In the example illustrated in Figure 3, the ratio is three DL-centered partitions to a UL-centered partition for a given cycle. It will be noted that the ratio between DL-centered partitions and UL-centered partitions can be selected for each application and / or based on network requirements or conditions and that a wide variety of reasons can be implemented.
[0051] This combination of an imbalance and unpredictability of its exact measurement, can cause problems in conventional TDD frame / partition structures. Specifically, if a UE or a programmed entity has data that it wants to transmit over the uplink, the UE needs to wait for an uplink transmission opportunity. With this partition structure, the time when such an uplink transmission opportunity can occur can vary, and can be unpredictable. In many cases, the time can be quite long, resulting in significant latency. This latency can be particularly problematic when the information the UE wants to transmit over the uplink is control feedback, which can be time sensitive or mission critical in many cases.
[0052] The unpredictable latency associated with asymmetric traffic can be at least partially alleviated using a partition structure that presents uplink transmission opportunities
Petition 870190041063, of 5/2/2019, p. 31/98
26/61 reasonable in each partition. Consequently, in some aspects of the present disclosure, TDD partitions can be structured as self-contained partitions.
[0053] Figure 4 illustrates exemplary structures of self-contained partitions 400 and 410. Broadly speaking, a self-contained partition is one in which programming, data transmission and data confirmation (feedback) are grouped into a single unit or partition self-contained, and that can be independent from other partitions. In the example of the DL 400-centered partition, all data in the DL 404 data portion can be programmed using information or programming grants in the DL 402 control region and in addition, all data in the 404 data portion can be confirmed (or negatively) confirmed) in the ACK 408 portion (UL control). Similarly, for the uplink-centered partition 410, all data in the data portion 416 can be programmed using information or programming leases in the DL 412 control region.
[0054] In the context of a multiple access network, channel resources are generally programmed, and each entity is synchronous in time. That is, each node using the network coordinates its use of resources, so that transmissions are carried out only during the allocated portion of the frame, and the time of each allocated portion is synchronized between the different nodes or network devices. A node acts as a programming entity, and one or more nodes can be programmed entities. The programming entity can be a base station or access point, or a UE on a D2D, P2P, and / or mesh network. THE
Petition 870190041063, of 5/2/2019, p. 32/98
27/61 programming entity manages resources on the carrier and allocates resources to other channel or carrier users, including programmed entities, such as one or more UEs on a cellular network.
[0055] Each partition 400, 410 is divided into portions of transmission (Tx) and reception (Rx). In the DL 400-centered partition, the first programming entity has an opportunity to transmit control information in the DL 402 control region, and then an opportunity to transmit data in the DL 404 data portion. The Tx 402 and 404 portions carry DL bursts in this case. After a portion of the guard period (GP) 406, the programming entity has an opportunity to receive a confirmed (ACK) / unconfirmed (NACK) signal or feedback in the ACK / NACK 408 portion from other entities using the carrier. The ACK / NACK 408 portion carries a UL burst. This frame structure is centered on the downlink, as more resources are allocated for transmissions in the downlink direction (for example, transmissions from the programming entity).
[0056] In one example, the DL 402 control region can be used to transmit a physical downlink control channel (PDCCH), and the DL 404 data portion can be used to transmit a DL data or data payload user. After the GP 406 portion, the programming entity can receive an ACK signal (or a NACK signal) from the programmed entity during the ACK / NACK 408 portion to indicate whether the data payload has been successfully received. The GP 406 portion can be programmed to accommodate variability in UL and DL timing. Per
Petition 870190041063, of 5/2/2019, p. 33/98
28/61 example, latencies due to switching of circuitry direction and / or RF antenna (for example, from DL to UL) and transmission path latencies can cause the programmed entity to transmit early on UL to match the timing DL. Such early transmission may interfere with the symbols received from the programming entity. Consequently, the GP 406 portion may allocate a period of time after the DL 404 data portion to prevent or reduce interference, wherein the GP 406 portion may provide an adequate period of time for the programming entity to switch its antenna / array direction. of RF circuits, for the over-the-air transmission time (OTA), and time for ACK processing by the programmed entity. Consequently, the GP 406 portion can provide an adequate period of time for the programmed entity to switch its antenna direction / RF circuitry (for example, from DL to UL), to process the data payload, and for the over-the-air (OTA) transmission. The duration of the GP 406 portion can be configured in terms of symbol periods. For example, the GP 406 portion can have a symbol period duration or multiple symbol periods. This frame structure is centered on the downlink, as more resources are allocated for transmissions in the downlink direction (for example, transmissions from the programming entity).
[0057] In the UL 410 centered partition, the first programmed entity has an opportunity to receive control information in the DL 412 control region. After a GP 414 portion, a UL transmission period
Petition 870190041063, of 5/2/2019, p. 34/98
29/61
418 can be programmed, including a UL 416 data portion and / or a UL 420 burst. The programmed entity has an opportunity to transmit data in the UL 416 data portion. The programmed entity can subsequently have an opportunity to transmit an ACK / NACK in the UL 420 burst. This frame structure is centered on an uplink, as more resources are allocated for transmissions in the uplink direction (for example, transmissions from the programmed entity). In some aspects of the disclosure, the GP portion may be optional.
[0058] In some aspects of the present disclosure, certain control information can be extracted or grouped in its own physical channel. In one example, the control information carried in the DL control information (DCI) on an LTE or similar network can be extracted or grouped on the physical downlink retransmission indicator channel (PDRICH). PDRICH can include a subset of information carried in a control subband or control region of a partition. For example, if the DCIs in a partition are segmented, so that resource allocation can be provided first in a partition, and later in the partition, the relay (RI) indicators can be provided in the PDRICH, then the programming entity you have additional time to determine whether to retransmit. Due to an adequate partition structure, including the location of the PDRICH, single interlaced transmissions may be permitted.
[0059] Figure 5 is a diagram that illustrates some examples of common DL bursts and common UL bursts,
Petition 870190041063, of 5/2/2019, p. 35/98
30/61 as they appear in each of a partition centered on DL 502 and a partition centered on UL 504. In the illustrated examples, common DL bursts 506 occur at the beginning of each partition, and common UL bursts 508 occur at the end of each partition. However, this is not necessarily the case, and falling within the scope of the present disclosure, such a common UL burst and common DL burst can appear anywhere within each respective partition. For example, in some network technologies, a partition includes two or more partitions, and common UL bursts and common DL bursts can be provided on each partition.
[0060] In some aspects of the disclosure, all common DL bursts 506 within any given partition (a UL centered partition or a DL centered partition) may have the same structure and / or all common UL bursts 508 within any A given partition (a UL-centered partition or a DL-centered partition) can have the same structure. Although these common bursts can carry any suitable information, in some examples, the common DL burst can be used to carry control information transmitted by the programming entity, including, but not limited to, programming information for UL or DL (or both); or, in multi-interleaved or non-self-contained partitions, physical layer acknowledgment (ACK) transmissions. For example, the common DL bursts 506 may include the DL 402 and 412 control regions of Figure 4. In addition, the common UL burst can be used to carry UL control information transmitted by the UE or programmed entity, including, but not limited to, signal in
Petition 870190041063, of 5/2/2019, p. 36/98
31/61 polling reference (SRS), a physical layer ACK or NACK, a programming request (SR), channel quality information (CQI), etc.
[0061] As with the self-contained partitions described above, using these common UL and DL bursts, latency can be reduced for mission-critical packages, such as control and feedback information, for the duration of, for example, a single partition . However, according to various aspects of the present disclosure, the possibility for this latency or delay to be controlled allows different delays or latencies to be provided. That is, due to the presence of the common DL burst 506 and the common UL burst 508 in each partition, the programmed entity and the programming entity can be allowed to send the control information carried in these common bursts with a configurable delay, which it can be independent of the UL / DL ratio, or the nature of the particular partition that currently occupies the channel (centered on DL or centered on UL). In addition, in additional aspects of the disclosure, UEs or entities programmed with different delays can be multiplexed over the channel, and can share those resources while still maintaining control over their respective delays.
[0062] In some examples, the common DL bursts and common UL bursts in each of a partition centered on DL 502 and a partition centered on UL 504 (see Figure 5) can be used to support at least two types of data transmission. UL NR 5G control channel. Figure 6 illustrates a transmission 600 in which a plurality of partitions 610a-610e includes partitions
Petition 870190041063, of 5/2/2019, p. 37/98
32/61 centered on DL 610a, 610b, 610c, 610e and a UL 610d centered partition. The plurality of partitions 610a-610e can span two or more partitions. The plurality of illustrated partitions 610a to 610e can be transmitted repeatedly and / or can be part of a larger partition pattern or arrangement. In one example, a DL 610a-centered partition includes one or more DL 602 bursts and a short-lived UL burst 604. In another example, a UL 610d-centered partition includes a short-lived DL burst 606 and a long-lived UL burst. duration 608. UL NR 5G control channel transmissions can be supported by the short burst UL 604 transmitted in a partition centered on DL 610a, and / or a long burst UL 608 on the partition centered on UL 610d.
[0063] In many examples, some or all of the UL control channels can be transmitted in a short burst UL 604. In some cases, the UL control channel can be transmitted in the last UL symbol or symbols of a partition 610a, 610b, 610c, 610e. The UL control channel can also be transmitted in a long-lasting UL 608 burst through multiple UL symbols to enhance coverage and / or provide increased power to the decoder. In general, short bursts UL 604 are likely to be configured more frequently than long bursts UL 608, and the use of short bursts UL 604 for UL control channel transmission can provide faster feedback to a station. base or other programming entity. In some cases, the use of long-lasting UL bursts 608 for UL control channel transmission can provide
Petition 870190041063, of 5/2/2019, p. 38/98
33/61 longer transmission times, which can € important to transmit larger volumes of feedback information and / or to accommodate link budget limitations that can affect an UE.
[0064] In accordance with certain aspects revealed in this document, the network can select between short bursts UL 604 and long bursts UL 608 for UL control channel transmissions based on factors, parameters and necessary applications associated with a link. The selection between short duration UL bursts 604 and long duration UL bursts 608 can determine or affect feedback delays. The network can configure the feedback delay by selecting between short bursts UL 604 and long bursts UL 608 for UL control channel transmissions.
[0065] In one example, the network can select between short UL bursts and long bursts UL for UL control channel transmissions based on the EU power reserve. The UE can be configured to operate within a power budget that can determine the power available to transmit to the UL control channel. The UE can use more power to transmit to a base station that is geographically remote to a base station that is geographically close. The power available for UL control channel transmissions can be limited by the available power reserve or available power margin. The reserve / margin of power can be defined as the difference between the budgeted power and the power used for other transmissions. THE
Petition 870190041063, of 5/2/2019, p. 39/98
34/61 power reserve / margin can indicate the power available for UL control channel transmissions. For example, when the UE is far from a base station, the power reserve may be small or even zero. The power reserve can be void when the UE is already transmitting at peak budgeted power. On the other hand, if the UE is located close to the base station, the power reserve can be relatively large. The UE can continuously report the power reserve to the base station. The network can select between short-lived UL bursts and long-lived UL bursts for UL control channel transmissions based on the reported EU power reserve.
[0066] Figure 7 illustrates examples 700, 720 of UL control channel transmission schedules that can be configured based on the reported EU power reserve. In a first example 700, the network recognizes that the UE has sufficient reserve to transmit the UL control channel in a short-lived UL burst 704. In this example 700, the network can configure the UE to provide UL 710 feedback that corresponds to a DL 702 burst in a short-lived UL burst 704 in the same partition.
[0067] In a second example 720, the network can recognize that the UE has insufficient reserve to reliably transmit the UL control channel in a short duration UL control burst 724. In this example 720, the network can configure the UE to provide UL 730, 732, 734 feedback that corresponds to one or more DL 722 bursts in a long-lasting UL control burst 728. The long-lasting UL control burst 728 can be provided in a different partition. The station
Petition 870190041063, of 5/2/2019, p. 40/98
35/61 base can configure the UE to transmit some or all of the UL 730, 732, 734 feedbacks to DL bursts that precede the long-lasting UL control burst 728 in the long-lasting UL control burst 728.
[0068] The UL 730, 732, 734 feedback can include a variety of different Uplink Control Information (UCI) fields. In some cases, the UE can be configured to transmit some or all of the UCI fields for each UL 730, 732, 734 feedback in a long duration UL control burst 728. In one example, the UE can be configured to transmit ACK bits in a short duration UL control burst 724, while other UCI fields are transmitted in a long duration UL control burst 728.
[0069] The network can configure physical resources used by the UE based on the UL control channel transmissions programmed for the UE. For example, when the base station has configured the UE to use short duration UL control bursts 724 and / or long duration UL control bursts 728, the base station may configure the UE to use certain physical resources, which can be identified as blocks of physical resources (PRBs). A base station can explicitly identify physical resources when configuring semistatic or dynamically configuring the UE to use certain PRBs. In one example, the base station can semi-statically configure the use of PRB in the UE through RRC signaling. In another example, the base station can dynamically configure the use of PRB in the UE through downlink control (DCI) information transmitted in the PDCCH, or another link control channel
Petition 870190041063, of 5/2/2019, p. 41/98
Descending 36/61.
[0070] In some cases, the UE may know implicitly the allocation of a PRE to UCI. For example, the UE can calculate the PRB for the UCIs using the location of the PDCCH and / or the location of the PDSCH. The UE can use different mapping formulas to locate a PRB used for UCIs in short duration UL control bursts 724 and long duration UL control bursts 728.
[0071] According to certain aspects, the base station can configure the UE with power control for short duration UL control bursts 724 which are different from the power control configured for long duration UL control bursts 728. That is , the power settings used by the UE when transmitting feedback in long duration UL control bursts 728 may differ from the power settings used by the UE to transmit in short duration UL control bursts 724. The base station can aggregate power through longer time span in long-duration UL control bursts 728 than the time span available in short duration UL control bursts 724. In one example, the UE can apply a fixed power deviation to operating points between short duration UL control bursts 724 and long duration UL control bursts 728. The difference in power control can be seen configured for closed circuit and / or open circuit power control schemes.
[0072] According to certain aspects, a network can select between bursts of UL control of
Petition 870190041063, of 5/2/2019, p. 42/98
37/61 short duration 724 and long duration UL control bursts 728 for UL control channel transmissions based on interference and / or UL loading.
[0073] In addition to power reserve considerations reported by UE, the network can configure feedback transmissions by the UE based on the measured or detected interference in UL transmissions. A base station can configure the UE to move UL feedback streams from short duration UL control bursts 724 to long duration UL control bursts 728, or vice versa, when one channel experiences more interference than the other. The interference can be attributed to other cells or UEs in the vicinity, for example.
[0074] In one example, interference can be determined or quantified by measuring the signal-interference-to-noise ratio (SINR) in the reception antennas of base stations and / or UEs. The base station can also receive interference measurements from other base stations. SINR measurements can be obtained using SRS or other pilot signals transmitted by the UE. A base station can transmit reference signals that provide channel estimation. A UE can measure channel quality using reference signals, and can feed CQI and RI values back to the base station.
[0075] In some cases, the network may configure feedback transmissions by the UE based on the network load. A base station can configure the UE to move UL feedback streams from short duration UL control bursts 724 to
Petition 870190041063, of 5/2/2019, p. 43/98
38/61 UL long bursts of control 728, when the network is loaded and the control channel capacity is limited in UL short bursts of control 724, for example.
[0076] Figure 8 illustrates examples 800, 820 of UL control channel transmissions that can be programmed based on the available UE processing power. In these examples 800, 820, short-lived UL control bursts 804, 824 are configured to be available on each partition carrying a long-lived DL 802, 822 burst. In the first example 800, the UE has sufficient processing capacity to decode a packet programmed in a long burst of DL 802 quickly and may be able to send an acknowledgment as 810 feedback immediately. For example, feedback 810 can be transmitted in a short duration UL control burst 804 within the same partition. In this first example 800, the UL feedback delay can be configured for null partitions (that is, transmit on the same partition). In the second example 820, the UE may not have sufficient processing capacity to decode a programmed packet in a DL 822 long-lived burst quickly and / or may not be able to send immediate confirmation on the short-lived UL control burst 824. In that according to example 820, the UE can transmit the feedback 830 after a partition delay K, where K> 0. In the second illustrated example 820, K = 1 partition delay. The partition delay may indicate a short duration UL control burst 826 or a short duration UL control burst
Petition 870190041063, of 5/2/2019, p. 44/98
39/61
828 to be used.
[0077] In some cases, uplink control transmission opportunities are not provided for each partition. In one example, the DL partition aggregation can be configured for the UE. In another example, a millimeter wave implementation may be involved and the base station may need to use beam formation for direct energy towards specific individual UEs in order to successfully receive and decode the UL signal. In such examples, an opportunity for UL feedback may not be provided on each partition, and the network may program the UE to transmit UL feedback based on the availability of UL control burst.
[0078] Figure 9 illustrates examples 900, 940 of UL feedback programming based on the availability of UL control burst. In many instances, the feedback delay is not fixed for all packets. In a first example 900, the base station can explicitly set up a feedback delay for each DL 902, 904, 906 partition. The base station can use DL 912, 914, 916 control information to explicitly inform the UE when feedback 922, 924, 926 for partitions can be sent. The base station can explicitly configure the feedback delay for each partition 902, 904, 906 in control information DL 912, 914, 916 transmitted at the beginning of each partition 902, 904, 906. In the first example 900, the base station configures the 2 partition delay applicable to the first 902 partition using
Petition 870190041063, of 5/2/2019, p. 45/98
40/61 DL 912 control information, and based on the programming of the next short duration UL control burst 908. Feedback 924, 926 for subsequent partitions can be programmed for 1 partition and 0 partition delays, respectively by configuring control DL 914 and 916, respectively.
[0079] In a second example 940, the feedback delay for each partition may be implicitly available to the UE. At the start of a group of DL partitions to which the feedback should be aggregated, the network can notify the UE of the timing of the next short duration UL control burst 944. In some cases, a base station can identify the control burst Short-lived UL 944 in DL 952 control information transmitted at the beginning of the first DL 942 partition. For each DL partition, the UE can determine delays to transmit feedback 946, 948, 950 associated with the corresponding DL partitions, and based on the programming of the partition in relation to the short duration UL control burst 944.
[0080] Figure 10 is a simplified block diagram that illustrates an example of a hardware implementation for a programming entity 1000 that employs a 1014 processing system. For example, programming entity 1000 can be user equipment ( UE), as illustrated in any one or more of Figures 1 and / or 2. In another example, the programming entity 1000 may be a base station, as illustrated in any one or more of Figures 1 and / or 2.

Examples of 1004 processors include microprocessors, microcontrollers, digital signal processors (DSPs), field programmable gate arrangements (FPGAs), programmable logic devices ( PLDs), state machines, port logic, discrete hardware circuits and other suitable hardware configured to perform the various features described throughout this disclosure.

The bus 1002 communicates in conjunction with several circuits that include one or more processors (usually represented by the processor 1004), a memory 1005 and computer-readable media (generally represented by the computer-readable medium 1006). The 1002 bus can also link several other circuits, such as timing sources, peripherals, voltage regulators and power management circuits, which are well known in the art and therefore will not be described further. A bus interface 1008 provides an interface between bus 1002 and a transceiver 1010. Transceiver 1010 provides a communication interface or a means to communicate with various other devices through a transmission medium. The transceiver can be operated and / or controlled using a 1026 transmitter control module that can include or interact with timers, framers, encoders and the like. Depending on the nature of the device, a 1012 user interface (for example, numeric keypad, display, speaker, microphone, joystick) may also be provided.
