BACKGROUND
[002] [002] The following refers in general to wireless communication, and more specifically to the configuration aspects of a new radio tracking reference signal.
[003] [003] Wireless communication systems are widely used to provide various types of communication content such as voice, video, packet data, messaging, broadcast etc. 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 fourth generation systems (46) as Evolution systems Long-term (LTE) or LTE-advanced (LTE-A) systems, and fifth generation (5G) systems that can be referred to as new Radio (NR) systems. These systems can employ technologies such as code division multiple access (CDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), or discrete Fourier transform spreading OFDM (DFT-S-OFDM) A wireless multiple access communication system can include multiple base stations or network access nodes, each supporting - simultaneously communication to multiple communication devices, which may otherwise be known. user equipment (EU).
[004] [004] Wireless communications systems seek to maintain frequency and time synchronization to allow communication between communication devices, including base stations and UEs. In LTE, a base station transmits a cell-specific reference signal across the entire partition and resource block, and a UE within the base station's range can perform time tracking, frequency tracking, or both, using a specific reference signal from cell received to maintain time and frequency synchronization with the base station. NR systems do not similarly transmit a cell-specific reference signal across every partition and resource block. Instead, a base station in NR systems can transmit a tracking reference signal that a UE can use for time tracking, frequency tracking or both. Conventional tracking reference signal transmission techniques fail to properly balance balances between time tracking and frequency tracking, resulting in degraded time and frequency synchronization, lower channel transmission capacity due to increased tracking reference signal overhead or similar. SUMMARY
[005] [005] The techniques described refer to improved methods, systems, devices or devices that support configuration aspects of a new radio tracking reference signal. In general, the techniques described provide a tracking reference signal (TRS) configuration that enables user equipment (UE) to maintain time and frequency synchronization with a base station, while also decreasing overhead resulting from the transmission of TRS bursts. A TRS is a multipurpose reference signal that can be used for time tracking, frequency tracking or the like. The TRS configuration described in the present invention can support multiple different uses to enable the UE to maintain time and frequency synchronization with a base station.
[006] [006] In some examples, the duration (for example, length) of a burst of TRS can vary in a TRS configuration to increase resource tracking. For example, a base station may select a set of burst durations (or lengths) for a burst of TRS, including a first burst duration and a second burst duration, the first burst duration being different from the second burst duration. The base station can transmit configuration information indicating the set of burst durations to a UE. The base station can transmit a first burst of TRS having the first burst duration and a second burst of TRS having the second burst duration. The UE can detect the first burst of TRS having the first burst duration and the second burst of TRS having the second burst duration based at least in part on the configuration information and the UE can perform resource tracking based on at least part in the first burst of TRS and second burst of TRS detected. In some cases, resource tracking can be time tracking to maintain time synchronization, frequency tracking to maintain frequency synchronization or the like.
[007] [007] In some examples, a frequency shift of a TRS transmission may vary in a TRS configuration to increase resource tracking. For example, a base station can select a frequency shift parameter. The frequency shift parameter can indicate an offset from a reference frequency and can be expressed in terms of several resource elements, a frequency band, a part of frequency bandwidth or the like. In some cases, the offset may be indicated for a set of symbol indices within a specific transmission time range (for example, on a partition), and the frequency offset parameter may specify an offset value for each index of symbol in the set of symbol indexes. The base station can transmit configuration information to a UE by indicating the frequency shift parameter, and the UE can receive the configuration information. The base station can transmit a TRS transmission having a frequency shift corresponding to the frequency shift parameter. The UE can detect the TRS transmission in a frequency band based at least in part on the frequency shift parameter, and perform resource tracking based at least in part on the detected TRS transmission.
[008] [008] A wireless communication method is described. The method may include receiving configuration information indicating a first burst duration and a second burst duration for a TRS burst, the first burst duration being different from the second burst duration, detecting a first burst of TRS having the first burst duration burst and a second burst of TRS having the second burst duration based at least in part on the configuration information and perform resource tracking based at least in part on the first burst of TRS and second burst of TRS detected.

[0059] [0059] The techniques described refer to improved methods, systems, devices or devices that support configuration aspects of a tracking reference signal in Rádio Novo. A tracking reference signal (TRS) can be configured to enable user equipment (UE) to maintain time and frequency synchronization with a base station, while also decreasing overhead resulting from the transmission of TRS bursts. TRS can be used for time tracking, frequency tracking or the like. The TRS configuration described here can support multiple different uses to enable the UE to maintain time and frequency synchronization with a base station. In some cases, TRS can be configured with higher layer signaling in a device-specific mode. For some receivers (for example, advanced receivers), the UE may use TRS for purposes other than time and frequency tracking, including estimation of Doppler propagation, delay propagation, power delay profile or similar.
[0060] [0060] In some examples, a duration (for example, extension) of a TRS burst can vary in a TRS configuration to increase resource tracking. For example, a base station may select a set of burst durations (for example, a set of burst lengths) for a TRS burst including a first burst duration and a second burst duration, where the first burst duration is different from the second burst duration. The base station can transmit configuration information indicating the set of burst durations to a UE. The base station can transmit configuration information indicating the set of burst durations to a UE. The base station can transmit a first burst of TRS having the first burst duration and a second burst of TRS having the second burst duration. The UE can detect the first burst of TRS having the first TRS duration and the second burst of TRS having the second burst duration based at least in part on the configuration information and the UE can perform resource tracking based at least in part in the first burst of TRS and the second burst of TRS detected. In some cases, resource tracking can be time tracking to maintain time synchronization, frequency tracking to maintain frequency synchronization or the like.
[0061] [0061] In some examples, a frequency shift of a TRS transmission may vary in a TRS configuration to increase resource tracking. For example, a base station can select a frequency shift parameter. The frequency shift parameter can indicate an offset relative to a reference frequency, and can be expressed in terms of a number of resource elements, a frequency band, a portion of frequency bandwidth, or the like. In some cases, the offset may be indicated for a set of symbol indices within a specific transmission time range (for example, on a partition) and the frequency offset parameter may specify an offset value for each symbol index in the set of symbol indices. The base station can transmit configuration information to a UE by indicating the frequency shift parameter and the UE can receive the configuration information. The base station can transmit a TRS transmission having a frequency shift corresponding to the frequency shift parameter. The UE can detect the TRS transmission in a frequency band based at least in part on the frequency shift parameter, and perform resource tracking based at least in part on the detected TRS transmission.
[0062] [0062] Aspects of the disclosure are initially described in the context of a wireless communication system. The wireless communication system can configure a TRS to increase the UE's ability to maintain frequency and time synchronization with a base station, while also decreasing overhead resulting from the transmission of TRS bursts. Aspects of the disclosure are further illustrated by and described with reference to device diagrams, system diagrams and flowcharts that refer to configuration aspects of a new radio tracking reference signal.
[0063] [0063] Figure 1 illustrates an example of a wireless communication system 100 according to various aspects of the present disclosure. The wireless communication system 100 includes base stations 105, UEs 115 and a core network 130. In some instances, the wireless communication system 100 may be a long-term Evolution (LTE) network, an LTE-Advanced network (LTE-A), or a new Radio network (NR). In some cases, the wireless communication system 100 can support increased broadband communications, ultra-secure communications (for example, mission critical), low-latency communications, or communications with low-complexity, low-cost devices.
[0064] [0064] Base stations 105 can communicate wirelessly with UEs 115 through one or more base station antennas. Base stations 105 described in the present invention may include or may be mentioned by those skilled in the art as a transceiver base station, a radio base station, an access point, a radio transceiver, a Nodeb, an eNodeB (eNB), a next generation Node B or giga-nodeB (any of which can be referred to as a gNB), a domestic NodeB, a domestic eNodeB, or some other suitable terminology. The wireless communication system 100 can include base stations 105 of different types (for example, macro or small cell base stations). The UEs 115 described here may be able to communicate with various types of base stations 105 and network equipment including macro eNBs, small cell eNBs, gNBs, relay base stations and the like.
[0065] [0065] Each base station 105 can be associated with a particular geographic coverage area 110 in which communications with several UEs 115 are supported. Each base station 105 can provide communication coverage for a respective geographic coverage area 110 through communication links 125 and communication links 125 between a base station 105 and an UE 115 can use one or more carriers. Communication links 125 shown on 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 an UE 115. Downlink transmissions can also be called direct link broadcasts while uplink broadcasts can also be called reverse link broadcasts.
[0066] [0066] Geographic coverage area 110 for a base station 105 can be divided into sectors comprising only a portion of geographic coverage area 110 and each sector can be associated with a cell. For example, each base station 105 can provide communication coverage for a macro cell, a small cell, a hot spot, or other types of cells, or various combinations thereof. In some examples, a base station 105 may be mobile and therefore provide communication coverage for a moving geographic coverage area 110. In some examples, different geographical coverage areas 110 associated with different technologies may overlap, and coverage areas overlapping geographic 110 associated with different technologies can be supported by the same base station 105 or different base stations
[0067] [0067] The term "cell" refers to a logical communication entity used to communicate with a base station 105 (for example, through a carrier) and can be associated with an identifier to distinguish neighboring cells (for example, an identifier physical cell (PCID), a virtual cell identifier (VCID) operating through the same or different carrier. In some examples, a carrier can support multiple cells, and different cells can be configured according to different protocol types (for example, machine type communication (MTC), narrowband Internet of things (NB-IoT), mobile broadband enhanced (eMBB),
[0068] [0068] UEs 115 can be dispersed throughout the wireless communication system 100, and each UE 115 can be stationary or mobile. A UE 115 can also be referred to as a mobile device, a wireless device, a remote device, a portable device, or a subscriber device, or some other suitable terminology, where the “device” can also be referred to as a unit, a station, a terminal, or a client. An UE 115 can also be a personal electronic device such as a cell phone, a personal digital assistant (PDA), a tablet computer, a laptop computer, or a personal computer. In some examples, an UE 115 may also refer to a wireless local loop station (WLL), an Internet of Things (IoT) device, an Internet of Everything (IOE) device, or an MTC Or similar device, which can be implemented in various items such as appliances, vehicles, meters or similar.
[0069] [0069] Some UEs 115, such as IoT or MTC devices, can be low cost or low complexity devices, and can provide automated communication between machines (for example, through Machine to Machine (M2M) communication). M2M or MTC communication can refer to data communication technologies that allow devices to communicate with each other or a 105 base station without human intervention. In some examples, communication
[0070] [0070] Some UEs 115 can be configured to employ operational modes that reduce energy consumption, such as half-duplex communications (for example, a mode that supports unidirectional communication through transmission or reception, but not transmission and reception simultaneously). In some examples, half-duplex communications can be performed at a reduced peak rate. Other energy conservation techniques for UEs 115 include entering a "deep sleep" energy saving mode when not involved in active communication or operating over a limited bandwidth (for example, according to narrowband communications). In some cases, UEs 115 can be designed to support critical functions (for example, mission critical functions) and a wireless communication system 100 can be configured to provide ultra secure communications for those functions.
[0071] [0071] In some cases, a UE 115 may also be able to communicate directly with other UEs 115 (for example, using a non-hierarchical protocol (P2P) or device to device (D2D)). One or more of a group of UEs 115 using D2D communication may be comprised in the geographical coverage area 110 of a base station 105. Other UEs 115 in such a group may be outside the geographical coverage area 110 of a base station 105, or be otherwise unable to receive transmissions from a base station 105. In some cases, groups of UES 115 communicating via D2D communications may use a one to many 1: M) system in which each UE 115 transmits to alternating UE 115 in the group. In some cases, a base station 105 makes it easy to program resources for D2D communications. in other cases, D2D communications are carried out between UEs 115 without the involvement of a base station 105.
[0072] [0072] Base stations 105 can communicate with core network 130 and with each other. For example, base stations 105 can interface with core network 130 through backhaul links 132 (for example, through an S1 or other interface). Base stations 105 can communicate with each other via backhaul links 134 (for example, via an X2 or other interface) directly (for example, directly between base stations 105) or indirectly (for example, via core network 130).
[0073] [0073] Core network 130 can provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity and other access, routing or mobility functions. Core network 130 can be a packet-developed core (EPC) that can include at least one mobility management entity (MME), at least one gateway in service (S-GW) and at least one gateway (P-GW) ) of Packet Data Network (PDN). MME can manage non-access layer functions (eg, control plan) such as mobility, authentication and bearer management for UEs 115 served by base stations 105 associated with EPC. User IP packets can be transferred via S-GW, which itself can be connected to the P-GW. The P-GW can provide IP address allocation as well as other functions. The P-GW can be connected to the IP services of network operators. Operator IP services may include Internet access, Intranet (s), an IP Multimedia Subsystem (IMS), or a Switched Packet Streaming Service (PS).
[0074] [0074] At least some of the network devices, such as a base station 105, may include subcomponents such as an access network entity, which can be an example of an access node controller (ANC). Each access network entity can communicate with UEs 115 through several other transmission and access network entities, which can be referred to as a radio head, an intelligent radio head, or a transmit / receive point (TRP). In some configurations, various functions of each access network entity or base station 105 can be distributed across multiple network devices (for example, radio heads and access network controllers) or consolidated into a single network device (for example, example, a base station
[0075] [0075] The wireless communication system 100 can operate using one or more frequency bands, typically in the range of 300 MHz to 300 GHz. In general, the 300 MHz to 3 GHz region is known as the ultra high frequency region (UHF) or decimeter band, since the wavelength range of approximately one decimeter to one meter in length. UHF waves can be blocked or redirected by buildings and environmental features. However, the waves can penetrate structures sufficiently for a macro cell to provide service to 115 internally located UEs. The transmission of UHF waves can be associated with smaller antennas and shorter range (for example, less than 100 km) compared to transmission using the lower frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) ) of the spectrum below 300 MHz.
[0076] [0076] The wireless communication system 100 can also operate in a super wing frequency region (SHF) using frequency bands from 3 GHz to 30 GHz, also known as the centimeter band. The SHF region includes stages such as the 5 GHz industrial, scientific and medical (ISM) bands, which can be used opportunistically by devices that can tolerate interference from other users.
[0077] [0077] The wireless communication system 100 can also operate in an extremely high frequency (EHF) region of the spectrum (for example, from 30 GHz to 300 GHz) also known as the millimeter band. In some instances, the wireless communication system 100 can support millimeter (mmW) wave communication between UEs 115 and base stations 105 and EHF antennas of the respective devices can be even smaller and more closely spaced than UHF antennas. In some cases, this can facilitate the use of antenna arrays in an UE 115. However, the spread of EHF transmissions can be subject to even greater atmospheric attenuation and shorter range than UHF or SHF transmissions. The techniques disclosed in the present invention can be employed through transmissions that use one or more different frequency regions, and designated use of bands across those frequency regions may differ by country or regulatory agency.
[0078] [0078] In some cases, the wireless communication system 100 may use both licensed and unlicensed radio spectrum bands. For example, wireless communication system 100 may employ License Assisted Access (LAA), LTE-unlicensed radio access technology (LTE-U) or NR technology in an unlicensed band such as the 5 GHz ISM band. When operating in unlicensed radio spectrum bands, wireless devices such as base stations 105 and UEs 115 can employ listening before speaking (LBT) procedures to ensure that a frequency channel is free before transmitting data. In some cases, operations on unlicensed bands may be based on a CA configuration in combination with CCs operating on a licensed band (for example, LAA). Unlicensed spectrum operations may include downlink transmissions, uplink transmissions,
[0079] [0079] In some examples, the base station 105 or UE 115 can be equipped with multiple antennas, which can be used to employ techniques such as diversity of transmission, diversity of reception, communications of multiple inputs multiple outputs (MIMO), or beam. For example, wireless communication system 100 can use a transmission scheme between a transmission device (for example, a base station 105) and a receiving device (for example, a UE 115), where the transmission device is equipped with multiple antennas and the receiving devices are equipped with one or more antennas. MIMO communications can employ multipath signal propagation to increase spectral efficiency by transmitting or receiving multiple signals across different spatial layers, which can be referred to as spatial multiplexing. The multiple signals can, for example, be transmitted by the transmission device via different antennas or different antenna combinations. Similarly, multiple signals may be received by the receiving device via different antennas or different antenna combinations. Each of the multiple signals can be referred to as a separate spatial stream, and can carry bits associated with the same data stream (for example, the same codeword) or different data streams.
[0080] [0080] Beam formation, which can also be referred to as spatial filtration, directional transmission or directional receiving, is a signal processing technique that can be used on a transmitting device or receiving device (for example, a base station 105 or an UE 115) to shape or direct a beam of antennas (for example, a transmission beam or the receiving beam) along a spatial path between the transmitting device and the receiving device. Beam formation can be achieved by combining the signals communicated through the antenna elements of a set of antennas so that signals propagating in specific orientations with respect to a set of antennas experience constructive interference while others experience destructive interference. The adjustment of signals communicated through the antenna elements can include a transmitting device or a receiving device applying certain phase and amplitude shifts to signals loaded through each of the antenna elements associated with the device. The settings associated with each of the antenna elements can be defined by a set of beamforming weights associated with a specific orientation (for example, with respect to the antenna set of the transmitting or receiving device, or with respect to some other orientation).
[0081] [0081] In one example, a base station 105 can use multiple antennas or antenna sets to conduct beamform operations for directional communications with a UE 115. For example, some signals (eg, sync signals, reference signals , beam selection signals, or other control signals) can be transmitted by a base station 105 multiple times in different directions, which may include a signal being transmitted according to different sets of beamforming weights associated with transmission directions many different. Transmissions in different beam directions can be used to identify (for example, base station 105 or a receiving device, such as a UE 115) a beam direction for subsequent transmission and / or receiving through base station 105. Some signals, such as data signals associated with a specific receiving device can be transmitted by a base station 105 in a single beam direction (for example, a direction associated with the receiving device, such as an UE 115). In some examples, the beam direction associated with transmissions along a single beam direction can be determined based at least in part on a signal that has been transmitted in different beam directions. For example, an UE 115 can receive one or more of the signals transmitted by the base station 105 in different directions, and the UE 115 can report to the base station 105 an indication of the signal it received with a higher signal quality, or a signal quality. otherwise acceptable signal. Although these techniques are described with reference to signals transmitted in one or more directions by a base station 105, a UE 115 may employ similar techniques to transmit signals multiple times in different directions (for example, to identify a beam direction for transmission or reception subsequent by UE 115), or transmit a signal in a single direction (for example, to transmit data to a receiving device).
[0082] [0082] A receiving device (for example, a UE 115, which can be an example of a mmW receiving device) can attempt multiple receiving beams when receiving multiple signals from base station 105, such as synchronization signals, reference signals, beam selection signals, or other control signals. For example, a receiving device may attempt multiple receiving directions by receiving through different subsets of antennas, by processing signals received according to different subsets of antennas, by receiving according to different receiving beamform weight sets applied to signals received on a plurality of antenna elements from a set of antennas, or by processing signals received according to different sets of receiving beamforming weights applied to signals received on a plurality of antenna elements from a set of antennas , any of which may be referred to “as“ listening ”according to different receiving beams or receiving directions. In some instances, a receiving device may use a single receiving beam to receive along a single beam direction (for example, when receiving a data signal). The single receiving beam can be aligned in a determined beam direction based at least in part on listening according to different receiving beam directions (for example, a beam direction determined to have a higher signal strength, ratio signal to higher noise, or otherwise acceptable signal quality based at least in part on listening according to multiple beam directions).
[0083] [0083] In some cases, the antennas of a 105 or UE 115 base station can be located in one or more antenna sets, which can support MIMO operations or transmit or receive beam formation. For example, one or more base station antennas or antenna assemblies can be located without an assembly in an antenna assembly, such as an antenna tower. In some cases, antennas or antenna sets associated with a base station 105 may be located in different geographic locations. A base station 105 can have a set of antennas with multiple rows and columns of antenna ports that base station 105 can use to support beaming communications with a UE 115. Similarly, a UE 115 can have one or more antenna sets that can support multiple beam forming or MIMO operations.
[0084] [0084] In some cases, wireless communication system 100 may be a packet-based network that operates according to a layered protocol stack. At the user level, communications in the Packet Data Convergence Protocol (PDCP) or carrier layer can be based on IP. A Radio Link Control (RLC) layer can in some cases perform packet segmentation and reassembly to communicate via logical channels. A Media Access Control (MAC) layer can perform priority handling and multiplexing of logical channels on transport channels. The MAC layer can also use hybrid auto-repeat request (HARQ) to provide transmission 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 a UE 115 and a base station 105 or core network 130 that supports radio bearers for data user plan. In the Physical layer (PHY), transport channels can be mapped to physical channels.
[0085] [0085] In some cases, UEs 115 and base stations 105 can support data retransmissions to increase the likelihood that data will be received successfully. HARQ feedback is a technique of increasing the likelihood that data will be received correctly over a 125 communication link. HARQ may include a combination of error detection (for example, using a cyclic redundancy check (CRC)), early correction error (FEC) and 9 retransmission (eg automatic retry request (ARQ)). HARQ can improve the transmission capacity at the MAC layer in poor radio conditions (for example, signal to noise conditions). In some cases, a wireless device can support HARQ feedback from the same partition, where the device can provide HARQ feedback on a specific partition for data received on an earlier symbol on the partition. In other cases, the device can provide HARQ feedback on a subsequent partition, or according to some other time interval.
[0086] [0086] Time intervals in LTE or NR can be expressed in multiples of a basic unit of time, which can, for example, refer to a sampling period of T. = 1 / 30,720,000 seconds. Time intervals for a communication resource can be arranged according to radio frames each having a duration of 10 milliseconds (ms), where the frame period can be expressed as Tr; = 307,200 T ;. the frame frames can be identified by a system frame number (SEN) ranging from 0 to 1023. Each frame can include 10 subframes numbered from 0 to 9, and each subframe can have a duration of 1 ms. A subframe can be further divided into 2 partitions each having a duration of 0.2 ms, and each partition can contain 6 or 7 modulation symbol periods (for example, depending on the length of the cyclic prefix preceded by each symbol period). Excluding the cyclic prefix, each symbol period can contain 2048 sampling periods. In some cases a subframe may be the smallest programming unit of the wireless communication system 100 and may be referred to as a transmission time interval (TTI). In other cases, a smaller programming unit of the wireless communication system 100 may be shorter than a subframe or may be dynamically selected (For example, in shortened TTIS bursts (sTTIS) or selected component carriers using sTTIs) .
[0087] [0087] In some wireless communications systems, a partition can be further divided into multiple mini-partitions containing one or more symbols. In some instances, a mini-partition or mini-partition symbol can be the smallest programming unit. Each symbol can vary in duration depending on the subcarrier spacing or frequency operating band, for example. In addition, some wireless communication systems may implement partition aggregation in which multiple partitions or mini-partitions are aggregated together and used for communication between an UE 115 and a base station 105.
[0088] [0088] The term "bearer" refers to a set of radio frequency spectrum resources having a physical layer structure defined to support communications over a communication link 125. For example, a bearer of a communication link 125 may include a portion of a radio frequency spectrum band that is operated according to physical layer channels for a given radio access technology. Each physical layer channel can carry user data, control information or other signaling. A carrier can be associated with a predefined frequency channel (for example, an absolute radio frequency channel number E-UTRA (EARFCN)) and can be positioned according to a channel scan for discovery by UEs 115. Carriers can be downlinked or uplink (for example, in an FDD mode) or be configured to load downlink and uplink communications (for example, in a TDD mode). In some examples, signal waveforms transmitted through a carrier can be composed of multiple subcarriers (for example, using multi-port modulation techniques (MCM) such as orthogonal frequency division multiplexing (OFDM) or DFT-s-OFDM) .
[0089] [0089] The organizational structure of carriers may be different for different radio access technologies (for example, LTE, LTE-A, NR etc.). For example, communication through a carrier can be organized according to TTIsS or partitions, each of which can include user data as well as control or signaling information to support decoding of user data. A carrier may also include dedicated acquisition signaling (for example, synchronization signals or system information, etc.) and control signaling that coordinates operation for the carrier. In some examples (for example, in a carrier configuration and aggregation), a carrier may also have signaling and acquisition or control signaling that coordinates operations for other carriers.
[0090] [0090] Physical channels can be multiplexed on a carrier according to various techniques. A physical control channel can be multiplexed on a downlink carrier, for example, using time division multiplexing (TDM) techniques, FDM techniques, or hybrid TDM-FDM techniques. In some examples, control information transmitted on a physical control channel can be distributed between different control regions in a cascade mode (for example, between a common control region or common search space and one or more specific control regions or specific EU search spaces).
[0091] [0091] A carrier can be associated with a specific bandwidth of the radio spectrum, and in some instances the carrier bandwidth can be referred to as a "system bandwidth" of the carrier or the wireless communication system 100. For example, carrier bandwidth can be one of several predetermined bandwidths for carriers of a specific radio access technology (for example, 1.4, 3, 5, 10, 15, 20, 40 or 80 MHz ). In some instances, each served UE 115 can be configured to operate across portions or the entire carrier bandwidth. In other examples, some UEs 115 can be configured for operation using a type of narrowband protocol that is associated with a predefined range or portion (for example, set of subcarriers or RBs) on a carrier (for example, “in-band deployment ”Of a type of narrowband protocol).
[0092] [0092] In a system employing MCM techniques, a feature element can consist of a symbol period (for example, a modulation symbol duration) and a subcarrier, where the symbol period and subcarrier spacing are inversely related. The number of bits loaded by each resource element may depend on the modulation scheme (for example, the order of the modulation scheme). Thus, the more resource elements that an UE 115 receives and the higher the order of the modulation scheme, the higher the data rate can be for the UE 115. In MIMO systems, a wireless communication resource can refer to a combination of a radio frequency spectrum resource, a time resource, and a spatial resource (for example, space layers) and the use of multiple space layers can further increase the data rate for communication with an UE 115.
[0093] [0093] Wireless communication system devices 1000 (for example, base stations 105 or UEs 115) may have a hardware configuration that supports communication across a specific carrier width, or may be configurable to support communications over one of a set of carrier bandwidths. In some examples, the wireless communication system 100 may include base stations 105 and / or UEs that can support simultaneous communications through carriers associated with more than a different carrier bandwidth.
[0094] [0094] The wireless communication system 100 can support communication with a UE 115 in multiple cells or carriers, a feature that can be referred to as carrier aggregation (CA) or multiple carrier operation. A UE 115 can be configured with multiple downlink CCs and one or more uplink CCs according to a carrier aggregation configuration. Carrier aggregation can be used with both FDD and TDD component carriers.
[0095] [0095] In some cases, the wireless communication system 100 may use enhanced component carriers (eCCs). An ecc can be characterized by one or more characteristics including wider frequency or carrier channel bandwidth, shorter symbol duration, shorter TTI duration, or modified control channel configuration. In some cases, an eCC can be associated with a carrier aggregation configuration in a dual connectivity configuration (for example, when multiple cells in service have a sub-optimal or not-ideal backhaul link). An eCC can also be configured for use on unlicensed spectrum or shared spectrum (for example, where more than one operator is allowed to use the spectrum). An eCC characterized by broad carrier bandwidth may include one or more segments that can be used by UEs 115 that are not able to monitor the entire carrier bandwidth or are otherwise configured to use a carrier bandwidth limited (for example, to conserve energy).
[0096] [0096] In some cases, an eCC may use a different symbol duration than other CCs, which may include use of a reduced symbol duration compared to the symbol durations of the other CCs. A shorter symbol life can be associated with increased spacing between adjacent subcarriers. A device, such as a UE 115 or base station 105, using eCCs can transmit broadband signals (for example, according to carrier bandwidth or channel frequency of 20, 40, 60 or 80 MHz) in reduced durations of symbol (for example, 16.67 microseconds). An eCC TTI can consist of one or multiple symbol periods. In some cases, the duration of TTI (that is, the number of symbol periods in a TTI) can be variable.
[0097] [0097] Wireless communication systems like an NR system can use any combination of licensed, shared and unlicensed spectrum bands, among others. The flexibility of eCC symbol duration and subcarrier spacing can allow the use of eCC across multiple spectra. In some instances, shared NR spectrum can increase spectrum usage and spectral efficiency, specifically through vertical (eg through frequency) and horizontal (eg through time) resource sharing.
[0098] [0098] Wireless communication system 100 can configure a TRS to enable an UE 115 to maintain time and frequency synchronization with a base station, while also decreasing overhead resulting from the transmission of TRS bursts. A base station 105 can specify a TRS burst pattern configuration to indicate which partitions include a TRS burst, and a set of resource elements from a TRS frequency band (for example, one or more resource blocks) that include TRS tones. For example, base station 105 may select a set of burst durations for a burst of TRS including a first burst duration and a second burst duration, where the first burst duration is different from the second burst duration. Base station 105 can transmit configuration information to UE 115 indicating the set of burst durations. Base station 105 can transmit a first burst of TRS having the first burst duration and a second burst of TRS having the second burst duration. UE 115 can detect the first burst of TRS having the first burst duration and the second burst of TRS having the second burst duration based at least in part on configuration information, and perform resource tracking based at least in part configuration information and perform resource tracking based at least in part on the first burst of TRS and the second burst of TRS detected. resource tracking can be time tracking to keep time tuning, frequency tracking to keep frequency sync or similar.
[0099] [0099] In some examples, a base station 105 can select a frequency shift parameter for a TRS transmission. The frequency shift parameter can indicate an offset from a reference frequency and can be expressed in terms of a number of resource elements, a frequency band, a portion of frequency bandwidth or the like. In some cases, the offset may be indicated for a set of symbol indices within a specific transmission time range (for example, on a partition) and the frequency offset parameter may specify an offset value for each symbol index in the set of symbol indices. The base station 105 can transmit configuration information to a UE 115 indicating the frequency shift parameter and the UE 115 can receive the configuration information. The base station 105 can transmit a TRS transmission having a frequency shift corresponding to the frequency shift parameter. UE 115 can detect TRS transmission in a frequency band based at least in part on the frequency shift parameter, and perform resource tracking based at least in part on the detected TRS transmission.
[00100] [00100] Figure 2 illustrates an example of a wireless communication system system 200 that supports configuration aspects of a tracking reference signal in Rádio Novo according to various aspects of the present disclosure. In some examples, system 200 may implement aspects of system 100. Some examples of system 200 may be a mmW wireless communication system. The system 200 can include a base station 205 and a UE 215, which can be examples of the corresponding devices described with reference to figure 1. The system 200 can also operate according to a radio access technology (RAT) such as Radio RAT new 5G.
[00101] [00101] In one example, base station 205 may select a TRS burst pattern configuration to support time and / or frequency tracking in UE 215. The TRS burst pattern configuration may include a set of configuration parameters TRS patterns that indicate a pattern of TRS bursts, and whose resource elements in one or more resource blocks include TRS tones. A TRS tone can be a transmission in a subcarrier and in a symbol period that has known characteristics (for example, known phase and amplitude), and the UE 215 can use the known characteristics for frequency and / or time tracking. A burst of TRS can be a transmission of a set of TRS tones at one or more transmission time intervals (TTIs) (for example, a number of symbol periods, partitions, subframes, frames or the like). For example, a burst of TRS can be communicated in a resource block that includes a set of resource elements, where each resource element corresponds to a subcarrier and symbol period. A burst of TRS can be a transmission of a set of one or more TRS tones in a subset of the set of resource elements of the resource block. Configuration information can specify a TRS burst pattern by indicating which resource blocks and partitions a TRS burst is transmitted in and which resource elements of a resource block include a TRS tone.
[00102] [00102] To indicate the burst pattern of TRS, base station 205 can select a value for one or more TRS configuration parameters, and can generate configuration information to indicate the selected values for each of one or more configuration parameters TRS. The base station 205 can transmit the configuration information to the UE 215, and transmit one or more bursts of TRS in a pattern as indicated in the configuration information. The UE 215 can receive and process the configuration information and monitor against a burst pattern of TRS according to the configuration information.
[00103] [00103] In some examples, the configuration information may include one or more TRS parameters that indicate aspects of a TRS burst pattern. As additionally described below, a TRS burst pattern can correspond to a set of partitions and TRS bursts can be transmitted on selected partitions of the partitions (for example, on selected partitions). The other partitions can be used to communicate control information and / or data between the base station 205 and one or more UEs 215. The control information and / or data can also be transmitted on the same partition as a burst of TRS, using elements of resources not occupied by TRS tones. In some examples, the TRS parameters can be specific to a single burst in a TRS pattern, or apply to multiple bursts in the TRS pattern.
[00104] [00104] In one example, a TRS X burst duration parameter can indicate a TRS burst duration. The X duration can be in terms of a number of TTIs (for example, a number of symbol periods, partitions, subframes, frames or the like). A TRS Y burst periodicity parameter can indicate a duration of a TRS burst pattern in terms of a number of TTIs. The burst pattern of TRS indicated by the configuration information can repeat all TTIs Y.
[00105] [00105] Some of the TRS parameters can also specify aspects of TRS tones in one or more bursts of TRS. A TRS Sr subcarrier spacing parameter; can indicate how many resource elements are between each subcarrier (for example, between each tone) in a specific symbol period for a burst of TRS. A TRS symbol spacing parameter S. can indicate a spacing between TRS symbols in a TTI (for example, in a partition). A TRS number parameter N can indicate a number of symbols (for example, OFDM symbols) per burst of TRS in a TTI (for example, on a partition). A TRS B bandwidth parameter can indicate bandwidth in terms of the number of resource blocks (RBs) of a burst of TRS. A burst of TRS can therefore be a transmission of a set of one or more TRS tones in selected resource elements from one or more resource blocks, as indicated by the configuration information.
[00106] [00106] In some examples, the TRS parameters discussed above can be independently configured for any TRS burst or series of TRS bursts. For example, a TRS parameter can be configured or changed despite the value and presence of any other TRS parameter. In some cases, some of the TRS parameters can be configured together. In some examples, only some of the TRS parameters are used, while in other examples, other TRS parameters are used.
[00107] [00107] Figure 3 illustrates an example of a burst pattern configuration of TRS 300 that supports configuration aspects of a tracking reference signal in Rádio Novo according to various aspects of the present disclosure. In some examples, the burst pattern configuration of TRS 300 may implement aspects of wireless communication systems 100 and 200.
[00108] [00108] A set of TTIS shown as partitions 330 and a TRS burst pattern having a single TRS burst having a duration 335 of a single partition and a burst pattern frequency of TRS 340 is shown in figure 3. In this example , the configuration information may indicate that a TRS duration parameter X is a partition (for example, x = 1) and the periodicity parameter y is five partitions (for example, Y = 5). As shown, bursts of TRS having a single partition duration are transmitted on O, 5, 10 partitions and this pattern can repeat every 5 partitions until the base station, such as base station 205, changes configuration information. The base station 205 can transmit to the UE, such as UE 215, configuration information indicating that the base station 205 can transmit a burst of TRS having a duration of one partition once every five partitions. In some examples, the configuration information can be a sequence of bits having a first set of bits to indicate the duration X and a second set of bits to indicate the periodicity parameter Y. The configuration information can indicate one or more than one TRS Sr subcarrier spacing parameter, a TRS S symbol spacing parameter, a TRS N number parameter, a TRS B bandwidth parameter, or similar, or any combination thereof. The UE 215 can receive and process configuration information and monitor for bursts of TRS according to configuration information. Other TRS configurations can also be used.
[00109] [00109] Figure 4 illustrates an example of a burst pattern configuration of TRS 400 that supports configuration aspects of a tracking reference signal in Rádio Novo according to various aspects of the present disclosure. In some examples, the burst pattern configuration of TRS 400 may implement aspects of wireless communication systems 100 and 200.
[00110] [00110] A set of TTIS shown as partitions 330-a and a TRS burst pattern having a single TRS burst having a duration 335- is shown in figure 4
[00111] [00111] In some examples, different burst pattern configurations of TRS may provide better performance for different use cases. The burst pattern of TRS in the example in figure 3, where (X = 1, Y = 5) may be suitable for time tracking, how to determine a delay, power delay profile estimation (PDP), or similar, for use in maintaining time synchronization. The burst pattern of TRS in the example in figure 4, where (X = 2, Y = 10) may be suitable for frequency tracking, such as Doppler estimation, or similar, to maintain frequency synchronization. Suitability for a specific TRS burst pattern configuration for time or frequency tracking may be a function of measurement techniques applied for tracking. For some types of measurements, correlation techniques can be applied to samples of a signal received in the frequency domain, and so the burst pattern configuration of TRS in figure 3 may be better suited for time tracking. Other correlation techniques can be applied to samples of a signal received in the time domain, and thus the burst pattern configuration of TRS in figure 4 may be better suited for frequency tracking.
[00112] [00112] A solution to support tracking both time and frequency can be to select a higher value for TRS X parameter and a lower value for TRS Y parameter. However, TRS overhead increases according to such a solution. For example, a TRS burst pattern setting where (X = 2, Y = 5) can be used, but overhead can, in some cases, be unacceptably high.
[00113] [00113] According to the techniques described in the present invention, configuration information may indicate a burst pattern of TRS where even each burst of
[00114] [00114] A set of TTIS shown as partitions 530 is shown in figure 5, and a burst pattern configuration of TRS 500 that includes bursts of TRS 535- a, 535-b that each have a different duration. In this example, the configuration information can include a combination of different parameters for different TRS bursts in the TRS burst pattern. Instead of the configuration information indicating a single value for duration X for all TRS bursts in a TRS burst pattern, the configuration information may specify different values for duration X for up to each TRS burst in a set of burst bursts. TRS. In the example shown, the configuration information can specify that a first burst of TRS has a duration of 535-a from one partition (for example, a TTI) and that a second burst of TRS has a duration of 535-b from two partitions. In another example, the configuration information can specify any desired duration for each TRS burst in a TRS burst pattern.
[00115] [00115] As shown, a burst of TRS having a duration of one partition is transmitted on partition O and a burst of TRS having a duration of two partitions is transmitted on partitions 5-6. This burst pattern of TRS can repeat every 10 partitions until base station 205 changes configuration information. Base station 205 can transmit configuration information to UE 215 indicating that base station 205 can transmit a burst of TRS having a duration of two partitions every ten partitions. The configuration information can be a sequence of bits having a first set of bits to indicate the duration X = 1 for the first burst of TRS, and a second set of bits to indicate the duration X = 2 for the second burst of TRS. Thus, the duration of a TRS burst can be different for each TRS burst in a TRS burst pattern, and TRS burst transmissions can alternate between different durations over a set of time intervals corresponding to a periodicity of the burst. burst pattern of TRS. This example shown and described can be applied to a TRS burst pattern having a set of TRS bursts including any number of TRS bursts and the configuration information may indicate different values for the X duration for up to each TRS burst in the set of bursts of TRS. In some instances, multiple bursts of TRS in the pool may have the same duration or each burst of TRS may have a different duration.
[00116] [00116] In some examples, the configuration information may indicate TRS parameters that vary from TRS burst to TRS burst in a TRS burst pattern, and may be unique for up to each TRS burst in the TRS burst pattern . For example, for a first TRS burst in a TRS burst pattern, the configuration information may indicate a first TRS Sr subcarrier spacing parameter, a first TRS symbol spacing parameter S :, a first TRS N number, a first TRS B bandwidth parameter, or similar, or any combination thereof. For a second burst of TRS in the burst pattern of TRS, the configuration information may indicate a second parameter of TRS subcarrier spacing parameter, a second parameter of TRS symbol spacing S :, a second parameter of TRS number N , a second bandwidth parameter of TRS B, or similar, or any combination thereof. In some instances, multiple TRS bursts in the TRS burst pattern may have the same value for one or more of the TRS parameters.
[00117] [00117] In some examples, multiple different TRS resources may be allocated per base station-UE pair (for example, per pair of UE-transmit / receive point (TRP)). Figure 6 illustrates an example of a burst pattern configuration of TRS 600 that supports configuration aspects of a tracking reference signal in Rádio Novo according to various aspects of the present disclosure. In some examples, the burst pattern configuration of TRS 600 can implement aspects of wireless communication systems 100 and 200.
[00118] [00118] In this example, configuration information can be specific to a specific TRS resource, and multiple TRS resources can be allocated to the UE 215. Each TRS resource can define a TRS burst pattern that specifies a value for one or more TRS parameters. UE 215 can apply a first configuration information corresponding to a first TRS resource, a second configuration information corresponding to a second TRS resource, etc. Some or all of the information and configuration instances may include an additional configuration parameter Z that specifies an offset. The UE 215 can process the offset to determine which (which) TTI (s) to monitor in relation to the respective TRS resources and the configuration of a TRS burst pattern to wait on one or more TTIs.
[00119] [00119] A set of TTIS shown as partitions 630 and bursts of TRS having different durations 635-a, 635-b corresponding to different TRS resources is shown in figure 6. TRS bursts for a first TRS 1 feature are shown using a first type of shading, and TRS bursts for a second TRS 2 feature are shown using a second type of shading. In the example shown, first configuration information for the TRS 1 feature can specify that a burst of TRS has a duration 635-a of a partition (for example, X = 1), a periodicity of 10 partitions (for example, Y = 10) and an offset of zero (for example, Z = 0). Second configuration information for the TRS 2 feature can specify that a burst of TRS has a duration 635-a of two partitions (for example, X = 2), a partition periodicity (for example, Y = 10) and an offset of five partitions (for example, Z = 5). In this example, a burst of TRS for TRS feature 1 occurs on partition 0 and repeats on partition 10 and every 10 partitions after until base station 205 changes the first configuration information. A burst of TRS for TRS 2 feature occurs on partitions 5-6, and repeats on partitions 15-16 and every 10 partitions thereafter until base station 205 changes second configuration information. It is noted that the techniques described in the present invention can be extended to more than two features of TRS.
[00120] [00120] In some instances, multiple TRS resources may collide. A collision can refer to an instance when multiple TRS resources are programmed at least in an overlay TTI (for example, in the same partition). In such a situation, a priority among TRS resources can be determined. In one example, the configuration information can explicitly specify an order of priority between different TRS resources, and when the UE 215 determines that there is a collision, it monitors for a burst of TRS corresponding to the configuration information of a resource. TRS having the highest priority in the order of priority of the TRS resources that collide. For example, if there are three TRS resources, with the TRS 1 resource having a higher priority, the TRS 2 resource having a higher next priority and the TRS 3 resource having a lower priority, the UE 215 applies the configuration information for the TRS 1 feature when there is a collision with any other TRS feature, and the configuration information for the TRS 2 feature when there is a collision with the TRS 3 feature. Base station 205 can similarly determine a order of priority of which TRS resource to use to transmit a burst of TRS when multiple bursts of TRS collide. Base station 205 or UE 215 can assign a burst order of priority. In one example, a burst with a longer duration may receive a higher priority. In another example, a burst with a shorter duration may receive a higher priority. Other examples give priority to bursts based on other characteristics as described in the present invention.
[00121] [00121] In other examples, UE 215 may apply one or more rules to implicitly determine an order of priority among the resources of TRS. For example, the order of priority can be based on values from a TRS parameter. UE 215 can determine values for a TRS parameter for each TRS resource, and determine an order of priority based on the determined values. For example, if TRS resources collide that have X = 1 and X = 2 durations respectively, the TRS resource with X = 2 can be determined to have a higher priority due to a rule indicating that a TRS parameter having a value bigger has priority. In other examples, a TRS parameter having a lower value can be determined to have a higher priority. If there is a tie, a value for a different TRS parameter can similarly be used to determine relative priority between TRS resources. Base station 205 can determine which TRS resource to use based on the order of priority when transmitting a TRS burst, and UE 215 can determine which TRS resource to expect based on the order of priority when receiving a TRS burst.
[00122] [00122] In some examples, a single TRS resource can be defined and configuration information can indicate a sequence of values for a TRS parameter in a TRS burst pattern, rather than defining a single value for the TRS parameter TRS. In one example, configuration information can define a sequence of values for each TRS parameter, and TRS bursts can be communicated in a TRS burst pattern according to the sequence. For example, a burst pattern of TRS shown in figure 6 can be defined by indicating the following sequence of values in the configuration information: duration X = (1, 2), time interval Y = (5, 5). Thus, in the first 5 time partitions, the duration of the burst of TRS is 1 partition and in the 5 second time partitions, the duration of the burst of TRS is 2 partitions. The burst pattern of TRS can then repeat.
[00123] [00123] In some examples, the configuration information may indicate a sequence of values for TRS parameters of any desired duration to define any type of TRS burst pattern. For example, a more complicated sequence for a TRS burst pattern can be defined (for example, X = (1, 2, 1, 1, 2), Y = (5, 5, 10, 10, 5)). The TRS burst pattern can repeat, according to the sequence of values indicated for each TRS parameter, until base station 205 changes the configuration information. In some examples, a sequence of maximum duration values for one or more TRS parameters can be defined. In this way, each burst duration X can be associated with a corresponding time slot duration Y, and base station 205 can transmit, and UE 215 can receive, bursts of TRS having respective durations in respective time intervals. Y.
[00124] [00124] The techniques described in the present invention can also support frequency hopping. Figure 7 illustrates an example of a burst pattern configuration of TRS 700 that supports configuration aspects of a tracking reference signal in Rádio Novo according to various aspects of the present disclosure. In some examples, the burst pattern configuration of TRS 700 may implement aspects of wireless communication systems 100 and 200. In TRS hop, a frequency of one or more tones of a TRS transmission may change over time, and the configuration information can include a TRS parameter indicating a hop pattern. In one example, the jump pattern can be a pitch jump pattern. In one example, the configuration information may include a TRS Or frequency shift parameter, alone or in combination with any of the TRS parameters described in the present invention. Together with the TRS Sr tone spacing parameter, the configuration information can indicate a TRS tone location on a TRS stage in a specific TRS symbol. The frequency offset parameter of TRS Or can be defined as a sequence of values that define a frequency hopping pattern of TRS tones in one or more transmission time intervals (for example, in a single partition).
[00125] [00125] Figure 7 resource grids 705-a, 705-b are shown showing frequency on the geometric axis y and time on the geometric axis x. each square in the resource grids 705 can represent a resource element that corresponds to a single subcarrier (for example, tone) and a single TTI (for example, a symbol period, an OFDM symbol period, etc.). band to communicate a burst of TRS can correspond with a specific TRS frequency band that can include one or more resource blocks. In this example, the TRS frequency band for each of the 705 resource grids can correspond to a single resource block that includes 12 subcarriers (for example, subcarriers 0 to 11). A partition can be defined to include 14 symbol periods and the resource grids 705 can show a partition (for example, symbol periods 0-13).
[00126] [00126] the frequency displacement parameter of TRS Or; you can define an offset from a reference frequency (for example, offset from a subcarrier of a specific reference element). The reference frequency can be a frequency of a subcarrier in a resource grid 705 (for example, subcarrier 11). In the example shown for resource grid 705-a, the configuration information may indicate that the frequency shift parameter of TRS Or; has a value of 1 (for example, Or = 1), the pitch spacing parameter of TRS S; has a value of 4 (for example, Sr; = 4), and the symbol spacing parameter of TRS S. has a value of 7 (for example, Se = 7). In some cases, the TRS symbol spacing parameter Sº “can indicate the distance between two TRS symbols in the same partition, and a location of a start symbol index can be specified or can be indicated in the configuration information. In some cases, configuration information may specify an offset value for each symbol index in a set of symbol indexes. In the example shown in resource grid 705-a, the starting symbol index can indicate symbol 3. In this way, the configuration information can indicate that a TRS tone is communicated on subcarrier 1 in the period of symbol 3 in the resource 705-a, and additional TRS tones are communicated in symbol 3 period which are separated by 4 subcarriers in the resource grid 705-a. In this way, TRS tones are also located in the resource elements in the symbol period 3 on subcarriers 5 and 9. In this example, the TRS symbol spacing parameter S. has a value of 7 and thus TRS tones are communicated on subcarriers 1, 5 and 9 of symbol period 10.
[00127] [00127] In some examples, the configuration information may indicate, for a burst burst pattern of TRS, a sequence of values for the frequency offset parameter of TRS Or to support frequency hopping of TRS tones. In resource grid 705-b, the TRS Or frequency shift parameter can be different for different partitions or different TRS symbol indexes in a partition. In the example shown, the frequency offset parameter of TRS Or can have a value of 3 in a first TRS symbol period (for example, in the symbol index 3) of a partition and a value of 1 in a second period of TRS symbol. TRS symbol for the same partition. Thus, TRS tones are communicated on subcarriers 3, 6 and 11 of the symbol period 3 of a partition on grid 705-b, and TRS tones are communicated on subcarriers 1, 5 and 9 of the symbol period 10 of the partition grade 705-b. beneficially, multiple TRS tones having different frequency offsets (for example, different frequency offsets) can be communicated on the same partition to obtain an increased pull range in delay spreading estimation, PDP estimation, or the like. The 705-b feature grid with S subcarrier spacing; = 4 and using frequency jump of two resource elements can provide the same estimation range as the Sr = 2 subcarrier space. Thus, the same estimation range can be obtained using half of the TRS tones, thereby reducing significantly overhead of TRS tone while maintaining comparable performance.
[00128] [00128] Some of the frequency hopping benefits can also be obtained on a larger bandwidth scale. Figure 8 illustrates an example of a TRS 800 burst pattern configuration that supports configuration aspects of a new Radio tracking reference signal in accordance with various aspects of the present disclosure. In some examples, the burst pattern configuration of TRS 800 can implement aspects of wireless communication systems 100 and 200. TRS subband hopping can be applied where a small bandwidth TRS feature can be configured with subband jump to cover a larger bandwidth. For example, the bandwidth of a TRS resource can be defined to include a set of some or more resource blocks that make up a fraction of a portion of bandwidth or a portion of entire bandwidth. A system bandwidth can include a set of distinct bandwidth parts.
[00129] [00129] The configuration information may include a configuration parameter indicating a frequency shift and / or jump pattern being used. For example, a portion of bandwidth can be divided into a set of available TRS bandwidths, and configuration information can specify a hop pattern for a burst of TRS. The burst of TRS can jump from an available TRS bandwidth to bandwidth according to the jump pattern. The configuration information can identify one or more partitions and one or more bandwidths available for a TRS transmission. The TRS transmission can include one or more bursts of TRS. In the example shown, three available TRS bandwidths can be defined (for example, TRS BW O, 1 and 2). The configuration information can specify that a TRS transmission is communicated on TRS BW 2 on partition O, TRS BW 1 on partition 5, and TRS BW O on partition 10. The hop pattern for TRS transmission can repeat every 15 partitions until the base station to change the configuration information. The configuration information can define other jump patterns. In another example, a system bandwidth can be divided into a set of available bandwidth parts and the configuration information can specify a hop pattern for a burst of TRS. The burst of TRS can jump from part of bandwidth to part of bandwidth according to the hop pattern. The TRS parameters described in the present invention can also vary from partition to partition.
[00130] [00130] Figure 9 illustrates an example of a 900 process flow that supports configuration aspects of a new radio tracking reference signal in accordance with various aspects of the present disclosure. In some examples, process flow 900 may implement aspects of wireless communication systems 100 and 200. Base station 905 is an example of base stations 105, 205 and UE 915 is an example of UEs 115, 215.
[00131] [00131] At 920, a base station 905 can select a set of burst durations for a TRS burst that includes a first burst duration and a second burst duration, where the first burst duration is different from the second burst duration . In other examples, three or more burst durations can be chosen.
[00132] [00132] In 925, base station 905 can transmit configuration information indicating the set of burst durations, including the first burst duration and the second burst duration, for a UE 915. In some cases, the base station 905 can allocate a set of TRS resources, including a first TRS resource and a second TRS resource, to the UE 915, where configuration information indicates that each of the resource set has been allocated to the UE 915. In some cases, the station base 905 can determine a time offset between the first resource and the second resource, where the configuration information indicates the time offset. In some cases, base station 905 may determine an order of priority for the first resource over the second resource, where configuration information indicates the order of priority.
[00133] [00133] In 930, UE 915 can receive and process configuration information. In some examples, UE 915 may determine, from the configuration information, that the first burst duration corresponds to a first time interval and the second burst duration corresponds to a second time interval, the second time interval occurring after the first time interval. In some examples, the UE 915 may determine, from configuration information, that TRS burst transmissions are programmed to switch between the first burst duration and the second burst duration at each time interval in a set of burst intervals. time. In some cases, the UE 915 may determine, from the configuration information, that the first burst duration corresponds to the first resource and the second burst duration corresponds to the second resource.
[00134] [00134] At 935, base station 905 can transmit a first burst of TRS having the first burst duration according to the configuration information. In 940, the UE 915 can monitor for and detect the first burst of TRS having the first burst duration according to the configuration information.
[00135] [00135] At 945, base station 905 can transmit a second burst of TRS having the second burst duration according to the configuration information. In some cases, base station 905 may alternate between transmitting the first burst of TRS and the second burst of TRS at each time slot in a set of time slots. At 950, UE 915 can monitor for and detect the second burst of TRS having the second burst duration according to the configuration information.
[00136] [00136] In 955, UE 915 can perform resource tracking based at least in part on the first burst of TRS and second burst of TRS detected. Resource tracking can be time tracking to maintain time synchronization, frequency tracking to maintain frequency synchronization, or similar. The UE 915 can also process received TRS tones for one or more Doppler propagation estimation, power delay profile (PDF) estimation, delay estimation or similar.
[00137] [00137] Figure 10 illustrates an example of a process flow 1000 that supports configuration aspects of a tracking reference signal in Rádio Novo according to various aspects of the present disclosure. In some examples, process flow 1000 can implement aspects of wireless communication systems 100 and 200. A base station 1005 is an example of base stations 105, 205 905, and UE 1015 is an example of UEs 115, 215, 1015.
[00138] [00138] In 1020 base station 1005 can select a frequency shift parameter. The frequency shift parameter can indicate an offset from a reference frequency (for example, subcarrier of a specific reference element) and can be expressed in terms of a number of resource elements, a frequency band, a part frequency bandwidth or similar. In some cases, base station 1005 may determine a first offset value (for example, offset value for a first partition symbol period) and a second offset value (for example, offset value for a second partition period) symbol other than a partition), where the frequency offset parameter indicates the first offset value and the second offset value. In some cases, the offset may be indicated for a set of symbol indices within a specific transmission time range (for example, on a partition), and the frequency offset parameter may specify an offset value for each index of symbol in the set of symbol indexes.
[00139] [00139] In 1025, the base station 1005 can transmit configuration information to a UE 105 indicating the frequency shift parameter and the UE 1015 can receive the configuration information. In some cases, base station 1005 can determine tone spacing for TRS transmission, and configuration information can indicate tone spacing.
[00140] [00140] In 1030, the UE 1015 can receive and process the configuration information. In 1035, base station 1005 can transmit a TRS transmission having a frequency shift corresponding to the frequency shift parameter. In 1040, the UE 1015 can monitor for and detect the transmission of TRS in a frequency band based at least in part on the frequency shift parameter. In 1045, UE 1015 can perform resource tracking based at least in part on the detected TRS transmission.
[00141] [00141] Beneficially, the techniques described here provide TRS burst pattern configurations that allow a UE to perform resource tracking while managing TRS overhead.

For example, transmitter 1220 can be an example of aspects of transceiver 1435 described with reference to figure 14. Transmitter 1220 can use a single antenna or a set of antennas.
[00158] [00158] Figure 13 shows a 1300 block diagram of a UE 1315 communications manager that supports configuration aspects of a new Radio tracking reference signal in accordance with aspects of the present disclosure. the UE 1315 communications manager can be an example of aspects of an EU 1115 communications manager, an EU 1215 communications manager, or an EU 1415 communications manager described with reference to figures 11, 12 and 14. The UE 1315 communications manager can include configuration component 1320, detection component 1325, tracking component 1330, resource allocator 1335, collision detector 1340, and priority component 1345.

[00237] [00237] The wireless communication system or systems 100 described here can support synchronous or asynchronous operation. For synchronous operation, base stations 105 may have similar frame timing, and transmissions from different base stations 105 may be approximately time aligned. For asynchronous operation, base stations 105 may have different frame timing, and transmissions from different base stations 105 may not be time aligned. The techniques described here can be used for synchronous or asynchronous operations.
[00238] [00238] Information and signals described here can be represented using any of a variety of different techniques and technologies. 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.

A general purpose processor can be a microprocessor, but in the alternative, the processor can be any processor, controller, microcontroller or conventional state machine. A processor can also be implemented 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).
[00240] [00240] The functions described here 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 in or transmitted via one or more instructions or code on a computer-readable medium. Other examples and implementations are included in the scope of the disclosure and attached claims. For example, due to the nature of software, functions described above can be implemented using software executed by a processor, hardware, firmware, wired connection, or combinations of any of these. Features implementing functions can also be physically located in various positions, including being distributed so that portions of functions are implemented in different physical locations.
[00241] [00241] 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 place to another. A non-transitory storage medium can be any available medium that can be accessed by a general purpose or special purpose computer. As an example, and not limitation, non-transitory computer-readable media may comprise random access memory (RAM), read-only memory (ROM), electrically erasable programmable read-only memory (EEPROM), flash memory, compact disc (CD) ROM or other optical disk storage, magnetic disk storage or other magnetic storage devices, or any other non-transitory media that can be used to transport or store desired program code media in the form of instructions or data structures and that can be accessed by a general purpose or special purpose computer, or a general purpose or special purpose processor. Also, any connection is properly called a computer-readable medium. 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 like infrared,

Also, as used here, the phrase “based on” will not be interpreted as a reference to a closed set of conditions. For example, an example 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 here, the phrase "based on" will be interpreted in the same way as the phrase "based at least in part on."
[00243] [00243] In the attached figures, components or similar characteristics may have the same reference label. In addition, several components of the same type can be distinguished by following the reference label with a dash and a second label that distinguishes between similar components. If only the first reference label is used in the specification, the description is applicable to any of the similar components having the same first reference label independent of the second reference label.
[00244] [00244] The description exposed here, with respect to the attached drawings, describes example configurations and does not represent all examples that can be implemented or that are included in the scope of the claims. The term "exemplifier" used here means "to serve as an example, instance or illustration" and 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, however, can be put into practice without these specific details. In some instances, well-known structures and devices are shown in the form of a block diagram to avoid obscuring the concepts of the examples described.
[00245] [00245] The description of the present invention is provided to enable a person skilled in the art to make or use the disclosure. Various modifications to the disclosure will be readily apparent to those skilled in the art and the generic principles defined here can be applied to other variations without departing from the scope of the disclosure. Thus, the disclosure is not limited to the examples and designs described here, but the broader scope compatible with the new principles and features disclosed in the present invention must be agreed.
