Description

Communications associated with different sets of sounding reference signal resources

Cross Reference to Related Applications

This patent application claims priority from U.S. provisional patent application No.63/261,865 entitled "COMMUNICATIONS ASSOCIATED WITH DIFFERENT SOUNDING REFERENCE SIGNAL RESOURCE SETS" filed on 9, 30, 2021 and U.S. non-provisional patent application No. 17/898,247 entitled "COMMUNICATIONS ASSOCIATED WITH DIFFERENT SOUNDING REFERENCE SIGNAL RESOURCE SETS" filed on 8, 2022, which are expressly incorporated herein by reference.

Technical Field

Aspects of the present disclosure relate generally to wireless communications and relate to techniques and apparatuses for communications associated with different sets of sounding reference signal resources.

Background

Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcast. A typical wireless communication system may employ multiple-access techniques capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, etc.). Examples of such multiple-access techniques include Code Division Multiple Access (CDMA) systems, time Division Multiple Access (TDMA) systems, frequency Division Multiple Access (FDMA) systems, orthogonal Frequency Division Multiple Access (OFDMA) systems, single carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-advanced is an enhanced set of Universal Mobile Telecommunications System (UMTS) mobile standards promulgated by the third generation partnership project (3 GPP).

A wireless network may include one or more base stations that support communication for a User Equipment (UE) or multiple UEs. The UE may communicate with the base station via downlink and uplink communications. "downlink" (or "DL") refers to the communication link from a base station to a UE, and "uplink" (or "UL") refers to the communication link from a UE to a base station.

The above multiple access techniques have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate at the urban, national, regional, and/or global level. The New Radio (NR), which may be referred to as 5G, is an enhanced set of LTE mobile standards promulgated by 3 GPP. NR is designed to better integrate with other open standards by improving spectral efficiency, reducing costs, improving services, utilizing new spectrum, and using Orthogonal Frequency Division Multiplexing (OFDM) with Cyclic Prefix (CP) on the downlink (CP-OFDM), CP-OFDM and/or single carrier frequency division multiplexing (SC-FDM) on the uplink (also known as discrete fourier transform spread OFDM (DFT-s-OFDM)), and support beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation, thereby better supporting mobile broadband internet access. As the demand for mobile broadband access continues to grow, further improvements to LTE, NR and other radio access technologies remain useful.

Detailed Description

Various aspects of the disclosure are described more fully hereinafter with reference to the accompanying drawings. This disclosure may, however, be embodied in many different forms and should not be construed as limited to any specific structure or function presented throughout this disclosure. Rather, these aspects are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art. It will be apparent to those skilled in the art that the scope of the present disclosure is intended to encompass any aspect of the disclosure disclosed herein, whether implemented independently of or in combination with any other aspect of the disclosure. For example, an apparatus may be implemented or a method practiced using any number of the aspects set forth herein. Furthermore, the scope of the present disclosure is intended to cover such an apparatus or method that is practiced using other structure, functionality, or both in addition to and other than the various aspects of the present disclosure set forth herein. It should be understood that any aspect of the disclosure disclosed herein may be embodied by one or more elements of the claims.

Several aspects of a telecommunications system will now be presented with reference to various apparatus and techniques. These devices and techniques will be described in the following detailed description and illustrated in the accompanying drawings by various blocks, modules, components, circuits, steps, processes, algorithms, etc. (collectively referred to as "elements"). These elements may be implemented using hardware, software, or a combination thereof. Whether such elements are implemented as hardware or software depends upon the particular application and design constraints imposed on the overall system.

Although aspects may be described herein using terms commonly associated with 5G or New Radio (NR) Radio Access Technologies (RATs), aspects of the disclosure may be applied to other RATs, such as 3G RATs, 4G RATs, and/or RATs after 5G (e.g., 6G).

Fig. 1 is a diagram illustrating an example of a wireless network 100 according to the present disclosure. The wireless network 100 may be or include elements of a 5G (e.g., NR) network and/or a 4G (e.g., long Term Evolution (LTE)) network, etc. Wireless network 100 may include one or more base stations 110 (shown as BS110a, BS110b, BS110c, and BS110 d), user Equipment (UE) 120 (sometimes referred to as a mobile station), or multiple UEs 120 (shown as UE 120a, UE 120b, UE 120c, UE 120d, and UE 120 e), and/or other network entities. Base station 110 is the entity in communication with UE 120. Base stations 110 (sometimes referred to as BSs) may include, for example, NR base stations, LTE base stations, nodes B, eNB (e.g., in 4G), gnbs (e.g., in 5G), access points, and/or transmit-receive points (TRPs). Each base station 110 may provide communication coverage for a particular geographic area. In the third generation partnership project (3 GPP), the term "cell" can refer to a coverage area of a base station 110 and/or a base station subsystem serving the coverage area, depending on the context in which the term is used.

The base station 110 may provide communication coverage for a macrocell, a picocell, a femtocell, and/or another type of cell. A macro cell may cover a relatively large geographic area (e.g., several kilometers in radius) and may allow unrestricted access by UEs 120 with service subscription. The pico cell may cover a relatively small geographic area and may allow unrestricted access by UEs 120 with service subscription. A femto cell may cover a relatively small geographic area (e.g., a residence) and may allow restricted access by UEs 120 having an association with the femto cell (e.g., UEs 120 in a Closed Subscriber Group (CSG)). The base station 110 for a macro cell may be referred to as a macro base station. The base station 110 for a pico cell may be referred to as a pico base station. The base station 110 for a femto cell may be referred to as a femto base station or a home base station. In the example shown in fig. 1, BS110a may be a macro base station for macro cell 102a, BS110b may be a pico base station for pico cell 102b, and BS110c may be a femto base station for femto cell 102 c. A base station may support one or more (e.g., three) cells.

In some examples, the cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of the moving base station 110 (e.g., a mobile base station). In some examples, base stations 110 may be interconnected with each other and/or to one or more other base stations 110 or network nodes (not shown) in wireless network 100 through various types of backhaul interfaces, such as direct physical connections or virtual networks, using any suitable transmission network.

The wireless network 100 may include one or more relay stations. A relay station is an entity capable of receiving a transmission of data from an upstream station (e.g., base station 110 or UE 120) and sending the transmission of data to a downstream station (e.g., UE 120 or base station 110). The relay station may be a UE 120 capable of relaying transmissions to other UEs 120. In the example shown in fig. 1, BS110d (e.g., a relay base station) may communicate with BS110a (e.g., a macro base station) and UE 120d in order to facilitate communications between BS110a and UE 120 d. The base station 110 relaying communications may be referred to as a relay station, a relay base station, a repeater, etc.

The wireless network 100 may be a heterogeneous network including different types of base stations 110 (such as macro base stations, pico base stations, femto base stations, relay base stations, etc.). These different types of base stations 110 may have different transmit power levels, different coverage areas, and/or different effects on interference in the wireless network 100. For example, macro base stations may have a high transmit power level (e.g., 5 to 40 watts), while pico base stations, femto base stations, and relay base stations may have a lower transmit power level (e.g., 0.1 to 2 watts).

The network controller 130 may be coupled to or in communication with a set of base stations 110 and may provide coordination and control for these base stations 110. The network controller 130 may communicate with the base stations 110 via backhaul communication links. Base stations 110 may communicate with each other directly or indirectly via wireless or wired backhaul communication links.

UEs 120 may be dispersed throughout wireless network 100, and each UE 120 may be stationary or mobile. UE 120 may include, for example, an access terminal, a mobile station, and/or a subscriber unit. UE 120 may be a cellular telephone (e.g., a smart phone), a Personal Digital Assistant (PDA), a wireless modem, a wireless communication device, a handheld device, a laptop computer, a cordless phone, a Wireless Local Loop (WLL) station, a tablet device, a camera, a gaming device, a netbook, a smartbook, a super-book, a medical device, a biometric device, a wearable device (e.g., a smartwatch, smart clothing, smart glasses, a smartwristband, smart jewelry (e.g., a smartring or smart bracelet)), an entertainment device (e.g., a music device, a video device, and/or a satellite radio), a vehicle component or sensor, a smart meter/sensor, an industrial manufacturing device, a global positioning system device, and/or any other suitable device configured to communicate via a wireless medium.

Some UEs 120 may be considered Machine Type Communication (MTC) or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and/or eMTC UEs may include, for example, robots, drones, remote devices, sensors, meters, monitors, and/or location tags, which may communicate with a base station, another device (e.g., a remote device), or some other entity. Some UEs 120 may be considered internet of things (IoT) devices and/or may be implemented as NB-IoT (narrowband IoT) devices. Some UEs 120 may be considered customer premises equipment. UE120 may be included within a housing that houses components of UE120, such as processor components and/or memory components. In some examples, the processor component and the memory component may be coupled together. For example, a processor component (e.g., one or more processors) and a memory component (e.g., memory) may be operatively coupled, communicatively coupled, electronically coupled, and/or electrically coupled.

In general, any number of wireless networks 100 may be deployed in a given geographic area. Each wireless network 100 may support a particular RAT and may operate on one or more frequencies. A RAT may be referred to as a radio technology, an air interface, etc. The frequencies may be referred to as carriers, frequency channels, etc. Each frequency may support a single RAT in a given geographical area in order to avoid interference between wireless networks of different RATs. In some cases, NR or 5G RAT networks may be deployed.

In some examples, two or more UEs 120 (e.g., shown as UE 120a and UE 120 e) may communicate directly using one or more side-uplink channels (e.g., without using base station 110 as an intermediary to communicate with each other). For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, a vehicle-to-everything (V2X) protocol (e.g., which may include a vehicle-to-vehicle (V2V) protocol, a vehicle-to-infrastructure (V2I) protocol, or a vehicle-to-pedestrian (V2P) protocol), and/or a mesh network. In such examples, UE 120 may perform scheduling operations, resource selection operations, and/or other operations described elsewhere herein as being performed by base station 110.

Devices of wireless network 100 may communicate using electromagnetic spectrum, which may be subdivided by frequency or wavelength into various categories, bands, channels, etc. For example, devices of wireless network 100 may communicate using one or more operating frequency bands. In 5G NR, two initial operating bands have been identified as frequency range names FR1 (410 MHz-7.125 GHz) and FR2 (24.25 GHz-52.6 GHz). It should be appreciated that although a portion of FR1 is greater than 6GHz, FR1 is commonly referred to in various documents and articles as the (interchangeably) "Sub-6 GHz" band. Similar naming problems sometimes occur with respect to FR2, which is often (interchangeably) referred to as the "millimeter wave" band in documents and articles, although it is different from the Extremely High Frequency (EHF) band (30 GHz-300 GHz) which is identified by the International Telecommunications Union (ITU) as the "millimeter wave" band.

The frequencies between FR1 and FR2 are commonly referred to as mid-band frequencies. Recent 5G NR studies have identified the operating band of these mid-band frequencies as frequency range designation FR3 (7.125 GHz-24.25 GHz). The frequency bands falling within FR3 may inherit FR1 characteristics and/or FR2 characteristics and may therefore effectively extend the characteristics of FR1 and/or FR2 into mid-band frequencies. In addition, higher frequency bands are currently being explored to extend 5G NR operation above 52.6 GHz. For example, three higher operating frequency bands have been identified as frequency range designations FR4a or FR4-1 (52.6 GHz-71 GHz), FR4 (52.6 GHz-114.25 GHz) and FR5 (114.25 GHz-300 GHz). Each of these higher frequency bands falls within the EHF frequency band.

In view of the above examples, unless specifically stated otherwise, it is to be understood that the term "sub-6GHz" or the like (if used herein) may broadly represent frequencies that may be below 6GHz, frequencies that may be within FR1, or frequencies that may include mid-band frequencies. Furthermore, unless specifically stated otherwise, it should be understood that the term "millimeter wave" or the like (if used herein) may broadly represent frequencies that may include mid-band frequencies, frequencies that may be at FR2, FR4-a or FR4-1 and/or FR5, or frequencies that may be within the EHF band. It is contemplated that the frequencies included in these operating bands (e.g., FR1, FR2, FR3, FR4-a, FR4-1, and/or FR 5) may be modified, and that the techniques described herein are applicable to those modified frequency ranges.

In some aspects, the mobile station may include a communication manager 140. As described in more detail elsewhere herein, the communication manager 140 may: receiving configuration information indicating a plurality of Sounding Reference Signal (SRS) resource sets, the configuration information indicating: a first set of SRS resource sets of the plurality of SRS resource sets associated with a first Downlink Control Information (DCI) format and a second set of SRS resource sets of the plurality of SRS resource sets associated with a second DCI format, wherein at least one of the first set or the second set comprises at least two of the plurality of SRS resource sets; and transmitting at least one uplink communication using at least one SRS resource of at least one SRS resource set of at least one of the first set or the second set based at least in part on the configuration information. Additionally or alternatively, the communication manager 140 may perform one or more other operations described herein.

In some aspects, the base station 110 may include a communication manager 150. As described in more detail elsewhere herein, the communication manager 150 may: transmitting configuration information indicating a plurality of SRS resource sets to the mobile station, the configuration information indicating: a first set of SRS resource sets of the plurality of SRS resource sets associated with the first DCI format, and a second set of SRS resource sets of the plurality of SRS resource sets associated with the second DCI format, wherein at least one of the first set or the second set comprises at least two of the plurality of SRS resource sets; and based at least in part on the configuration information, receiving at least one uplink communication using at least one SRS resource of at least one SRS resource set of at least one of the first set or the second set. Additionally or alternatively, the communication manager 150 may perform one or more other operations described herein.

As indicated above, fig. 1 is provided as an example. Other examples may differ from that described with respect to fig. 1.

Fig. 2 is a schematic diagram illustrating an example 200 of a base station 110 in a wireless network 100 in communication with a UE 120 in accordance with the present disclosure. Base station 110 may be equipped with a set of antennas 234a through 234T, such as T antennas (T.gtoreq.1). UE 120 may be equipped with a set of antennas 252a through 252R, such as R antennas (r≡1).

At base station 110, transmit processor 220 may receive data intended for UE 120 (or a set of UEs 120) from data source 212. Transmit processor 220 may select one or more Modulation and Coding Schemes (MCSs) for UE 120 based at least in part on one or more Channel Quality Indicators (CQIs) received from UE 120. Base station 110 may process (e.g., encode and modulate) data for UE 120 based at least in part on the MCS selected for UE 120 and may provide data symbols for UE 120. Transmit processor 220 may process system information (e.g., for semi-Static Resource Partitioning Information (SRPI)) and control information (e.g., CQI requests, grants, and/or upper layer signaling) and provide overhead symbols and control symbols. The transmit processor 220 may generate reference symbols for reference signals (e.g., cell-specific reference signals (CRS) or demodulation reference signals (DMRS)) and synchronization signals (e.g., primary Synchronization Signals (PSS) or Secondary Synchronization Signals (SSS)). A Transmit (TX) multiple-input multiple-output (MIMO) processor 230 may perform spatial processing (e.g., precoding) on the data symbols, control symbols, overhead symbols, and/or reference symbols, if applicable, and may provide a set of output symbol streams (e.g., T output symbol streams) to a corresponding set of modems 232 (e.g., T modems), shown as modems 232a through 232T. For example, each output symbol stream may be provided to a modulator component (shown as MOD) of modem 232. Each modem 232 may process a respective output symbol stream (e.g., for OFDM) using a respective modulator component to obtain an output sample stream. Each modem 232 may also process (e.g., convert to analog, amplify, filter, and/or upconvert) the output sample stream using a corresponding modulator component to obtain a downlink signal. Modems 232a through 232T may transmit a set of downlink signals (e.g., T downlink signals) via a set of corresponding antennas 234 (e.g., T antennas) (shown as antennas 234a through 234T).

At UE 120, a set of antennas 252 (shown as antennas 252a through 252R) may receive downlink signals from base station 110 and/or other base stations 110 and a set of received signals (e.g., R received signals) may be provided to a set of modems 254 (e.g., R modems) (shown as modems 254a through 254R). For example, each received signal may be provided to a demodulator component (shown as DEMOD) of modem 254. Each modem 254 may use a corresponding demodulator component to condition (e.g., filter, amplify, downconvert, and/or digitize) the received signal to obtain input samples. Each modem 254 may further process the input samples (e.g., for OFDM) using a demodulator assembly to obtain received symbols. MIMO detector 256 may obtain the received symbols from modem 254, may perform MIMO detection on the received symbols, if applicable, and may provide detected symbols. Receive processor 258 may process (e.g., demodulate and decode) the detected symbols, may provide decoded data for UE 120 to a data sink 260, and may provide decoded control information and system information to a controller/processor 280. The term "controller/processor" may refer to one or more controllers, one or more processors, or a combination thereof. The channel processor may determine a Reference Signal Received Power (RSRP) parameter, a Received Signal Strength Indicator (RSSI) parameter, a Reference Signal Received Quality (RSRQ) parameter, and/or a CQI parameter, etc. In some examples, one or more components of UE 120 may be included in housing 284.

The network controller 130 may include a communication unit 294, a controller/processor 290, and a memory 292. For example, the network controller 130 may include one or more devices in a core network. The network controller 130 may communicate with the base station 110 via a communication unit 294.

The one or more antennas (e.g., antennas 234a through 234t and/or antennas 252a through 252 r) may include or be included in one or more antenna panels, one or more antenna groups, one or more sets of antenna elements, and/or one or more antenna arrays, etc. The antenna panel, antenna group, antenna element set, and/or antenna array may include one or more antenna elements (within a single housing or multiple housings), a set of coplanar antenna elements, a set of non-coplanar antenna elements, and/or one or more antenna elements coupled to one or more transmit and/or receive components (such as one or more components in fig. 2).

On the uplink, at UE 120, transmit processor 264 may receive and process data from data source 262 as well as control information from controller/processor 280 (e.g., for reports including RSRP, RSSI, RSRQ and/or CQI). Transmit processor 264 may generate reference symbols for one or more reference signals. The symbols from transmit processor 264 may be precoded by a TX MIMO processor 266 if applicable, further processed by modem 254 (e.g., for DFT-s-OFDM or CP-OFDM), and transmitted to base station 110. In some examples, modem 254 of UE 120 may include a modulator and a demodulator. In some examples, UE 120 includes a transceiver. The transceiver may include any combination of antennas 252, modems 254, MIMO detector 256, receive processor 258, transmit processor 264, and/or TX MIMO processor 266. The processor (e.g., controller/processor 280) and memory 282 may use the transceiver to perform aspects of any of the methods described herein (e.g., with reference to fig. 3-13).

At base station 110, uplink signals from UE 120 and other UEs may be received by antennas 234, processed by modems 232 (e.g., the demodulator components of modems 232, shown as DEMODs), detected by MIMO detector 236 (if applicable), and further processed by receive processor 238 to obtain decoded data and control information transmitted by UE 120. The receive processor 238 may provide the decoded data to a data sink 239 and the decoded control information to a controller/processor 240. The base station 110 may include a communication unit 244 and may communicate with the network controller 130 via the communication unit 244. Base station 110 may include a scheduler 246 to schedule one or more UEs 120 for downlink and/or uplink communications. In some examples, modem 232 of base station 110 may include a modulator and a demodulator. In some examples, base station 110 includes a transceiver. The transceiver may include any combination of antennas 234, modems 232, MIMO detector 236, receive processor 238, transmit processor 220, and/or TX MIMO processor 230. A processor (e.g., controller/processor 240) and memory 242 may use a transceiver to perform aspects of any of the methods described herein (e.g., with reference to fig. 3-13).

As described in more detail elsewhere herein, controller/processor 240 of base station 110, controller/processor 280 of UE 120, and/or any other component of fig. 2 may perform one or more techniques associated with communication associated with different sets of Sounding Reference Signal (SRS) resources. For example, controller/processor 240 of base station 110, controller/processor 280 of UE 120, and/or any other component in fig. 2 may perform or direct operations such as process 1000 of fig. 10, process 1100 of fig. 11, and/or other processes as described herein. Memories 242 and 282 may store data and program codes for base station 110 and UE 120, respectively. In some examples, memory 242 and/or memory 282 may include a non-transitory computer-readable medium storing one or more instructions (e.g., code and/or program code) for wireless communication. For example, the one or more instructions, when executed by one or more processors of base station 110 and/or UE 120 (e.g., directly, or after compilation, conversion, and/or interpretation), may cause the one or more processors, UE 120, and/or base station 110 to perform or direct operations such as process 1000 of fig. 10, process 1100 of fig. 11, and/or other processes as described herein. In some examples, the execution instructions may include execution instructions, conversion instructions, compilation instructions, and/or interpretation instructions, among others.

In some aspects, a mobile station (e.g., UE 120) includes: means for receiving, by the mobile station, configuration information indicating a plurality of SRS resource sets, the configuration information indicating: a first set of SRS resource sets of the plurality of SRS resource sets associated with the first DCI format, and a second set of SRS resource sets of the plurality of SRS resource sets associated with the second DCI format, wherein at least one of the first set or the second set comprises at least two of the plurality of SRS resource sets; and/or means for: at least one uplink communication is transmitted by the mobile station based at least in part on the configuration information using at least one SRS resource of at least one SRS resource set of at least one of the first set or the second set. The means for a mobile station to perform the operations described herein can include, for example, one or more of communication manager 140, antenna 252, modem 254, MIMO detector 256, receive processor 258, transmit processor 264, TX MIMO processor 266, controller/processor 280, or memory 282.

In some aspects, a base station includes: means for transmitting, by the base station to the mobile station, configuration information indicating a plurality of SRS resource sets, the configuration information indicating: a first set of SRS resource sets of the plurality of SRS resource sets associated with the first DCI format, and a second set of SRS resource sets of the plurality of SRS resource sets associated with the second DCI format, wherein at least one of the first set or the second set comprises at least two of the plurality of SRS resource sets; and/or means for: at least one uplink communication is received by the base station based at least in part on the configuration information using at least one SRS resource of at least one SRS resource set of at least one of the first set or the second set. The means for a base station to perform the operations described herein may include, for example, one or more of communication manager 150, transmit processor 220, TX MIMO processor 230, modem 232, antenna 234, MIMO detector 236, receive processor 238, controller/processor 240, memory 242, or scheduler 246.

Although the blocks in fig. 2 are shown as distinct components, the functionality described above with respect to the blocks may be implemented in a single hardware, software, or combined component or in various combinations of components. For example, the functions described with respect to transmit processor 264, receive processor 258, and/or TX MIMO processor 266 may be performed by controller/processor 280 or under the control of controller/processor 280.

As noted above, fig. 2 is provided as an example. Other examples may differ from that described with respect to fig. 2.

Fig. 3 illustrates an example logical architecture of a distributed RAN 300 according to this disclosure.

The 5G access node 305 may include an access node controller 310. The access node controller 310 may be a Central Unit (CU) of the distributed RAN 300. In some aspects, the backhaul interface to the 5G core network 315 may terminate at the access node controller 310. The 5G core network 315 may include a 5G control plane component 320 and a 5G user plane component 325 (e.g., a 5G gateway), and a backhaul interface for one or both of the 5G control plane and the 5G user plane may terminate at the access node controller 310. Additionally or alternatively, the backhaul interface to one or more neighbor access nodes 330 (e.g., another 5G access node 305 and/or LTE access node) may terminate at the access node controller 310.

Access node controller 310 may include one or more TRP 335 and/or may be in communication with one or more TRP 335 (e.g., via an F1 control (F1-C) interface and/or an F1 user (F1-U) interface). TRP 335 may be a Distributed Unit (DU) of distributed RAN 300. In some aspects, TRP 335 may correspond to base station 110 described above in connection with fig. 1. For example, different TRPs 335 may be included in different base stations 110. Additionally or alternatively, multiple TRPs 335 may be included in a single base station 110. In some aspects, base station 110 may include a CU (e.g., access node controller 310) and/or one or more DUs (e.g., one or more TRPs 335). In some cases, TRP 335 may be referred to as a cell, panel, antenna array, or array.

TRP 335 may be connected to a single access node controller 310 or to multiple access node controllers 310. In some aspects, the dynamic configuration of the split logic functions may exist within the architecture of the distributed RAN 300. For example, a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, and/or a Medium Access Control (MAC) layer may be configured to terminate at the access node controller 310 or the TRP 335.

In some aspects, the plurality of TRPs 335 may transmit communications (e.g., same communications or different communications) in the same Transmission Time Interval (TTI) (e.g., time slot, micro-slot, subframe, or symbol) or in different TTIs using different quasi-co-located (QCL) relationships (e.g., different spatial parameters, different Transmission Configuration Indicator (TCI) states, different precoding parameters, and/or different beamforming parameters). In some aspects, the TCI state may be used to indicate one or more QCL relationships. TRP 335 may be configured to provide services to UE 120 alone (e.g., using dynamic selection) or jointly (e.g., using joint transmission with one or more other TRPs 335).

As indicated above, fig. 3 is provided as an example. Other examples may differ from that described with respect to fig. 3.

Fig. 4 is a diagram illustrating an example 400 of multi-TRP communication (sometimes referred to as multi-panel communication) in accordance with the present disclosure. As shown in fig. 4, multiple TRP 405 may be in communication with the same UE 120. TRP 405 may correspond to TRP 335 described above in connection with fig. 3.

Multiple TRPs 405 (shown as TRP a and TRP B) may communicate with the same UE 120 in a coordinated manner (e.g., using coordinated multipoint transmission) to improve reliability and/or increase throughput. TRP 405 may coordinate such communications via interfaces between TRP 405 (e.g., backhaul interfaces and/or access node controllers 310). The interface may have less delay and/or higher capacity when TRP 405 is located at the same base station 110 (e.g., when TRP 405 is a different antenna array or panel of the same base station 110) and may have greater delay and/or lower capacity (compared to co-location) when TRP 405 is located at a different base station 110. Different TRP 405 may communicate with UE 120 using different QCL relationships (e.g., different TCI states), different demodulation reference signal (DMRS) ports, and/or different layers (e.g., layers of multi-layer communication).

In a first multi-TRP transmission mode (e.g., mode 1), a single Physical Downlink Control Channel (PDCCH) may be used to schedule downlink data communications for a single Physical Downlink Shared Channel (PDSCH). In this case, multiple TRPs 405 (e.g., TRP a and TRP B) may transmit communications to UE 120 on the same PDSCH. For example, a communication may be transmitted using a single codeword with different spatial layers for different TRPs 405 (e.g., where one codeword maps to a first set of layers transmitted by a first TRP 405 and to a second set of layers transmitted by a second TRP 405). As another example, a communication may be transmitted using multiple codewords, where different codewords are transmitted by different TRPs 405 (e.g., using different sets of layers). In either case, different TRP 405 may use different QCL relationships (e.g., different TCI states) for different DMRS ports corresponding to different layers. For example, the first TRP 405 may use a first QCL relationship or a first TCI state for a first set of DMRS ports corresponding to a first layer set, and the second TRP 405 may use a second (different) QCL relationship or a second (different) TCI state for a second (different) set of DMRS ports corresponding to a second (different) layer set. In some aspects, a TCI state in DCI (e.g., sent on PDCCH, such as DCI format 1_0 or DCI format 1_1) may indicate a first QCL relationship (e.g., by indicating a first TCI state) and a second QCL relationship (e.g., by indicating a second TCI state). The first TCI state and the second TCI state may be indicated using a TCI field in the DCI. In general, the TCI field may indicate a single TCI state (for single TRP transmission) or multiple TCI states (for multi TRP transmission as discussed herein) in the multi TRP transmission mode (e.g., mode 1).

In a second multi-TRP transmission mode (e.g., mode 2), multiple PDCCHs may be used to schedule downlink data communications for multiple corresponding PDSCH (e.g., one PDCCH for each PDSCH). In this case, the first PDCCH may schedule a first codeword to be transmitted by the first TRP 405, and the second PDCCH may schedule a second codeword to be transmitted by the second TRP 405. Further, a first DCI (e.g., transmitted by a first TRP 405) may schedule a first PDSCH communication associated with a first set of DMRS ports having a first QCL relationship (e.g., indicated by a first TCI state) for the first TRP 405, and a second DCI (e.g., transmitted by a second TRP 405) may schedule a second PDSCH communication associated with a second set of DMRS ports having a second QCL relationship (e.g., indicated by a second TCI state) for the second TRP 405. In this case, the DCI (e.g., with DCI format 1_0 or DCI format 1_1) may indicate a corresponding TCI state for TRP 405 corresponding to the DCI. The TCI field of the DCI indicates a corresponding TCI state (e.g., the TCI field of the first DCI indicates a first TCI state and the TCI field of the second DCI indicates a second TCI state).

As indicated above, fig. 4 is provided as an example. Other examples may be different than described with respect to fig. 4.

Fig. 5 is a diagram illustrating an example 500 of DCI scheduling multiple cells (e.g., multiple TRPs) according to the present disclosure. As shown in fig. 5, base station 110 and UE120 may communicate with each other.

Base station 110 may send DCI 505 to UE 120 that schedules multiple communications for UE 120. The plurality of communications may be scheduled for at least two different cells (e.g., two different TRPs). In some cases, a cell may be referred to as a Component Carrier (CC). In some cases, DCI for scheduling communications for a cell via which the DCI is transmitted may be referred to as self-carrier (or self-cell) scheduling DCI. In some cases, DCI for scheduling communications for a cell via which the DCI is transmitted may be referred to as cross-carrier (or cross-cell) scheduling DCI. In some aspects, DCI 505 may be cross-carrier scheduling DCI and may or may not be self-carrier scheduling DCI. In some aspects, DCI 505 carrying communications in at least two cells may be referred to as a combined DCI.

In example 500, DCI 505 schedules communications for a first cell 510 (shown as CC 0) that carries DCI 505, schedules communications for a second cell 515 (shown as CC 1) that does not carry DCI 505, and schedules communications for a third cell 520 (shown as CC 2) that does not carry DCI 505. In some aspects, DCI 505 may schedule communications on a different number of cells (e.g., two cells, four cells, five cells, etc.) than shown in fig. 5. The number of cells may be greater than or equal to two.

The communication scheduled by DCI 505 may include a data communication such as a PDSCH communication or a Physical Uplink Shared Channel (PUSCH) communication. For data communication, DCI 505 may schedule a single Transport Block (TB) across multiple cells, or multiple TBs may be scheduled separately in multiple cells. Additionally or alternatively, the communications scheduled by DCI 505 may include reference signals, such as channel state information reference signals (CSI-RS) or SRS. For reference signals, DCI 505 may trigger a single resource for reference signal transmission across multiple cells or multiple resources may be scheduled separately for reference signal transmission in multiple cells. In some cases, the scheduling information in DCI 505 may be indicated once and reused for multiple communications (e.g., on different cells), such as Modulation and Coding Schemes (MCSs), resources to be used for Acknowledgements (ACKs) or Negative Acknowledgements (NACKs) for communications scheduled by DCI 505, and/or resource allocations for scheduled communications to save signaling overhead.

As indicated above, fig. 5 is provided as an example. Other examples may differ from that described with respect to fig. 5.

Fig. 6 is a diagram illustrating an example 600 of physical channels and reference signals in a wireless network according to the present disclosure. As shown in fig. 6, the downlink channel and the downlink reference signal may carry information from the base station 110 to the UE 120, and the uplink channel and the uplink reference signal may carry information from the UE 120 to the base station 110.

As shown, the downlink channel may include a Physical Downlink Control Channel (PDCCH) carrying DCI, a Physical Downlink Shared Channel (PDSCH) carrying downlink data, or a Physical Broadcast Channel (PBCH) carrying system information, etc. In some aspects, PDSCH communications may be scheduled by PDCCH communications. As further shown, the uplink channel may include a Physical Uplink Control Channel (PUCCH) carrying Uplink Control Information (UCI), a Physical Uplink Shared Channel (PUSCH) carrying uplink data, or a Physical Random Access Channel (PRACH) for initial network access, or the like. In some aspects, UE 120 may send Acknowledgement (ACK) or Negative Acknowledgement (NACK) feedback (e.g., ACK/NACK feedback or ACK/NACK information) in UCI on PUCCH and/or PUSCH.

As further shown, the downlink reference signals may include Synchronization Signal Blocks (SSBs), channel State Information (CSI) reference signals (CSI-RS), demodulation reference signals (DMRS), positioning Reference Signals (PRS), phase Tracking Reference Signals (PTRS), or the like. As also shown, the uplink reference signal may include SRS, DMRS, PTRS, or the like.

SSBs may carry information for initial network acquisition and synchronization, such as Primary Synchronization Signals (PSS), secondary Synchronization Signals (SSS), PBCH, and PBCH DMRS. SSBs are sometimes referred to as sync signal/PBCH (SS/PBCH) blocks. In some aspects, the base station 110 may transmit multiple SSBs on multiple corresponding beams, and these SSBs may be used for beam selection.

The CSI-RS may carry information for downlink channel estimation (e.g., downlink CSI acquisition) that may be used for scheduling, link adaptation, or beam management, etc. Base station 110 may configure the CSI-RS set for UE120 and UE120 may measure the configured CSI-RS set. Based at least in part on the measurements, UE120 may perform channel estimation and may report channel estimation parameters (e.g., in CSI reporting) such as Channel Quality Indicator (CQI), precoding Matrix Indicator (PMI), CSI-RS resource indicator (CRI), layer Indicator (LI), rank Indicator (RI), or Reference Signal Received Power (RSRP) to base station 110. Base station 110 may use CSI reports to select transmission parameters for downlink communications to UE120, such as a number of transmission layers (e.g., rank), a precoding matrix (e.g., precoder), a Modulation and Coding Scheme (MCS), or a refined downlink beam (e.g., using a beam refinement procedure or a beam management procedure), etc.

The DMRS may carry information for estimating the wireless channel to demodulate an associated physical channel (e.g., PDCCH, PDSCH, PBCH, PUCCH or PUSCH). The design and mapping of DMRS may be specific to the physical channel for which the DMRS is used for estimation. DMRS is UE-specific, may be beamformed, may be limited to scheduled resources (e.g., rather than transmitting on wideband), and may transmit only when necessary. As shown, the DMRS is used for both downlink and uplink communications.

PTRS may carry information for compensating for oscillator phase noise. In general, phase noise increases as the oscillator carrier frequency increases. Thus, PTRS may be utilized at high carrier frequencies (such as millimeter wave frequencies) to mitigate phase noise. PTRS may be used to track the phase of the local oscillator and to achieve suppression of phase noise and Common Phase Error (CPE). As shown, PTRS is used for both downlink communications (e.g., on PDSCH) and uplink communications (e.g., on PUSCH).

PRS may carry information for enabling UE120 to make timing or ranging measurements based on signals transmitted by base station 110 to improve observed time difference of arrival (OTDOA) positioning performance. For example, PRS may be a pseudo-random Quadrature Phase Shift Keying (QPSK) sequence mapped in a diagonal pattern with an offset in frequency and time to avoid collisions with cell-specific reference signals and control channels (e.g., PDCCH). In general, PRSs may be designed to improve the detectability of UE120, and UE120 may need to detect downlink signals from multiple neighboring base stations in order to perform OTDOA-based positioning. Thus, UE120 may receive PRSs from multiple cells (e.g., a reference cell and one or more neighboring cells) and may report a Reference Signal Time Difference (RSTD) based on OTDOA measurements associated with PRSs received from the multiple cells. In some aspects, base station 110 may then calculate the location of UE120 based on the RSTD measurements reported by UE 120.

The SRS may carry information for uplink channel estimation, which may be used for scheduling, link adaptation, precoder selection, beam management, or the like. Base station 110 may configure one or more SRS resource sets for UE120 and UE120 may transmit SRS on the configured SRS resource sets. The SRS resource set may have a configured purpose such as uplink CSI acquisition, downlink CSI acquisition for reciprocity-based operation, uplink beam management, and the like. Base station 110 may measure SRS, may perform channel estimation based at least in part on the measurement, and may use the SRS measurement to configure communication with UE 120.

As indicated above, fig. 6 is provided as an example. Other examples may differ from that described with respect to fig. 6.

Fig. 7 is a diagram illustrating an example 700 of SRS resource sets according to the present disclosure.

Base station 110 may configure UE 120 with one or more SRS resource sets to allocate resources for SRS transmission by UE 120. For example, the configuration for the SRS resource set may be indicated in a Radio Resource Control (RRC) message (e.g., an RRC configuration message or an RRC reconfiguration message). As indicated by reference numeral 705, the SRS resource set may include one or more resources (e.g., shown as SRS resources) that may include time resources and/or frequency resources (e.g., slots, symbols, resource blocks, and/or periods of time resources). As shown by reference numeral 710, the SRS resources may include one or more antenna ports on which to transmit SRS (e.g., in time-frequency resources). Thus, the configuration for the set of SRS resources may indicate one or more time-frequency resources in which to transmit SRS, and may indicate the antenna ports on which to transmit SRS in those time-frequency resources. In some aspects, the configuration for the SRS resource set may indicate a use case for the SRS resource set (e.g., in an SRS-SetUse information element). For example, the SRS resource set may have use cases of antenna switching, codebook, non-codebook, or beam management.

The antenna-switched SRS resource set may be used to indicate downlink CSI using reciprocity between uplink and downlink channels. For example, when reciprocity exists between uplink and downlink channels, base station 110 may use antenna-switched SRS (e.g., SRS transmitted using resources in an antenna-switched SRS resource set) to obtain downlink CSI (e.g., to determine a downlink precoder to use for communicating with UE 120).

When base station 110 indicates an uplink precoder to UE 120, a set of codebook SRS resources may be used to indicate uplink CSI. For example, when base station 110 is configured to indicate an uplink precoder to UE 120 (e.g., using a precoder codebook), base station 110 may use a codebook SRS (e.g., an SRS transmitted using resources of a codebook SRS resource set) to obtain uplink CSI (e.g., to determine an uplink precoder to be indicated to UE 120 and used by UE 120 for communication with base station 110). In some aspects, a virtual port (e.g., a combination of two or more antenna ports) with maximum transmit power may be supported for at least the codebook SRS.

When UE 120 selects an uplink precoder (e.g., instead of the uplink precoder indicated by base station 110 to be used by UE 120), a set of non-codebook SRS resources may be used to indicate uplink CSI. For example, when UE 120 is configured to select an uplink precoder, base station 110 may use a non-codebook SRS (e.g., an SRS transmitted using resources in a non-codebook SRS resource set) to obtain uplink CSI. In this case, the non-codebook SRS may be precoded using a precoder selected by UE 120 (e.g., the precoder may be indicated to base station 110).

The beam-management SRS resource set may be used to indicate CSI for millimeter wave communications.

SRS resources may be configured to be periodic, semi-persistent (sometimes referred to as semi-persistent scheduling (SPS)) or aperiodic. The periodic SRS resources may be configured via a configuration message indicating a period of the SRS resources (e.g., slot level period in which the SRS resources occur every Y slots) and a slot offset. In some cases, the periodic SRS resources may be always activated and may not be dynamically activated or deactivated. Semi-persistent SRS resources may also be configured via configuration messages indicating periods and slot offsets for the semi-persistent SRS resources and may be dynamically activated and deactivated (e.g., using DCI or Medium Access Control (MAC) Control Elements (CEs) (MAC-CEs)). The aperiodic SRS resource may be dynamically triggered, for example, via DCI (e.g., UE-specific DCI or group-common DCI) or MAC-CE.

In some aspects, UE 120 may be configured with a mapping between SRS ports (e.g., antenna ports) and corresponding SRS resources. UE 120 may transmit SRS on a particular SRS resource using the SRS ports indicated in the configuration. In some aspects, SRS resources may span M adjacent symbols within a slot (e.g., where M equals 1,2, or 4). UE 120 may be configured with X SRS ports (e.g., where x+.4). In some aspects, each of the X SRS ports may be mapped to a corresponding symbol of an SRS resource and used to transmit SRS in the symbol.

As shown in fig. 7, in some aspects different SRS resource sets (e.g., with different use cases) indicated to UE 120 may overlap (e.g., in time and/or frequency, e.g., in the same slot). For example, as shown by reference numeral 715, a first set of SRS resources (e.g., shown as SRS resource set 1) is shown with an antenna switching use case. As shown, this example set of antenna-switched SRS resources includes a first SRS resource (shown as SRS resource a) and a second SRS resource (shown as SRS resource B). Thus, antenna port 0 and antenna port 1 may be used to transmit antenna-switched SRS in SRS resource a (e.g., a first time-frequency resource) and antenna port 2 and antenna port 3 may be used to transmit antenna-switched SRS in SRS resource B (e.g., in a second time-frequency resource).

As indicated by reference numeral 720, the second set of SRS resources (e.g., shown as SRS resource set 2) may be a codebook use case. As shown, this example set of codebook SRS resources includes only the first SRS resource (shown as SRS resource a). Thus, antenna port 0 and antenna port 1 may be used to transmit codebook SRS in SRS resource a (e.g., a first time-frequency resource). In this case, UE 120 may not use antenna port 2 and antenna port 3 to transmit codebook SRS in SRS resource B (e.g., a second time-frequency resource).

As indicated above, the base station may schedule or configure uplink transmissions for the UE on the uplink. In some cases, the base station may configure the UE to perform codebook-based PUSCH transmission, which may be PUSCH transmission configured to be performed in SRS resource sets with the purpose of "codebook" configured for the UE. The SRS resource set may include N SRS resources (e.g., where n=1, 2, 3, or 4), and the base station may configure the number of SRS ports and spatial relationship information on a per SRS resource basis for each of the SRS resources.

The base station may indicate SRS resources for PUSCH transmission to the UE by indicating SRS resources in an SRS Resource Indicator (SRI) field in a downlink communication (e.g., DCI communication with format 0_1 or format 0_2, which may be uplink scheduling DCI) of the scheduled PUSCH transmission. The UE may use the same spatial transmission filter for PUSCH transmission as the indicated SRS resources and may use the number of SRS ports of the indicated SRS resources as the number of antenna ports for PUSCH transmission.

In some cases, the downlink communication may also indicate a Transmitted Precoding Matrix Indicator (TPMI) and a number of layers for PUSCH transmission. For example, if the downlink communication is a DCI communication, the DCI communication may include precoding information and a layer number field indicating TPMI and the number of layers. The precoding information and number of layers field may include a code point (e.g., a plurality of bits indicating or representing a particular value) identifying an index associated with a row or column in a table or another type of data structure. The row or column may indicate the number of layers and TPMI associated with the index.

In some cases, the base station may configure the UE to transmit multiple repetitions of the same PUSCH transmission (e.g., multiple repetitions of the same PUSCH transmission block), where each repetition may be directed to a TRP of multiple TRP of the multiple TRP configuration, an antenna panel of multiple antenna panels of the multi-panel configuration, or an antenna of multiple antennas of the multi-antenna configuration. Thus, if the access link between the UE and the TRP (or antenna panel or antenna) is blocked such that no repetition of the transmission to the TRP is received, another repetition of the transmission to another TRP may be received such that the PUSCH transmission may be decoded.

In some cases, the UE may be configured to send repetitions of PUSCH transmissions in different time domain resources (e.g., slots/minislots). Each time domain resource configured for repetition of PUSCH transmission may be referred to as a PUSCH transmission occasion. This may enable the UE to transmit PUSCH repetitions with different SRS resource sets (e.g., for different TRPs). However, DCI format 0_2 has a reduced number of bits relative to DCI format 0_1 for identifying the SRS resource set to be used by the UE for scheduling PUSCH repetition. Thus, when a UE is configured for multi-TRP PUSCH repetition (e.g., resulting in 3 or 4 different SRS resource sets) scheduled via one or two DCI formats, the complexity of the UE may increase when determining which SRS resources and/or SRS resource sets are to be used for PUSCH repetition, as more options for selecting SRS resource sets and ordering PUSCH repetitions are available.

As indicated above, fig. 7 is provided as an example. Other examples may differ from that described with respect to fig. 7.

Some techniques and apparatuses described herein enable a UE to be individually configured to schedule multi-TRP transmissions for different DCI formats without increasing the UE complexity involved in determining which SRS resources and/or SRS resource sets are to be used for PUSCH repetition scheduled by the different DCI formats. For example, the UE may be configured with a first set of SRS resource sets for a first DCI format (e.g., DCI format 0_1) and a second set of SRS resource sets for a second DCI format (e.g., DCI format 0_2). For example, the SRS resource set in the second set (e.g., for DCI format 0_2) may include the first N SRS resources in the corresponding SRS resource set in the first set (e.g., for DCI format 0_1, where N is equal to the number of SRS resources configured for the corresponding SRS resource set) and the order in which uplink communications are transmitted may be determined based on the lowest SRS resource set identifier being transmitted first. When receiving DCI scheduling uplink communication (e.g., PUSCH repetition), the UE may select SRS resources for the uplink communication based on a format of the DCI. This may enable the UE to schedule PUSCH repetition for multiple DCI formats and for multiple TRPs using the same rule for each DCI format (e.g., lowest SRS resource set identifier first). This may reduce the complexity of the UE to process DCI scheduling uplink communications, save resources (e.g., processing resources, power resources, etc.) of the UE and enable efficient multi-TRP network communications, which may reduce wireless network congestion and lead to improved communication quality over the wireless network.

Fig. 8 is a diagram illustrating an example 800 of communications associated with different sets of sounding reference signal resources in accordance with the present disclosure. As shown in fig. 8, a mobile station (e.g., UE 120) may communicate (e.g., send uplink transmissions and/or receive downlink transmissions) with a base station (e.g., base station 110). The mobile station and the base station may be part of a wireless network (e.g., wireless network 100).

As indicated by reference numeral 805, the base station may transmit and the mobile station may receive configuration information. In some aspects, a mobile station may receive configuration information from another device (e.g., from another base station or another mobile station). In some aspects, the mobile station may receive the configuration information via RRC signaling and/or Medium Access Control (MAC) signaling (e.g., MAC control element (MAC CE)). In some aspects, the configuration information may include an indication of one or more configuration parameters for selection by the mobile station (e.g., one or more configuration parameters already known to the mobile station) and/or explicit configuration information for use by the mobile station to configure the mobile station, etc.

In some aspects, the configuration information may indicate: the mobile station is to transmit uplink communications using different SRS resource sets based on the format of DCI for scheduling the uplink communications and the SRS resource sets configured separately for the different DCI formats. For example, the configuration information may indicate two sets of SRS resource sets to be associated with two different DCI formats, such as a first set of SRS resource sets for DCI format 0_1 and a second set of SRS resource sets for DCI format 0_2. At least one of the sets includes at least two SRS resource sets (e.g., for multi-TRP uplink communications such as multi-TRP PUSCH repetition).

In some aspects, the configuration information may indicate: in each set of SRS resource sets (e.g., configured separately for different DCI formats), the SRS resource set with the lowest SRS resource set identifier is considered the first SRS resource set for uplink communications transmitted by the mobile station. In some aspects, the set of SRS resources in the second set may include SRS resources that match other SRS resources in another set of SRS resources in the first set. For example, the first set of SRS resources for the second set (e.g., for DCI format 0_2) may include the first N SRS resources in the first set of SRS resources for the first set (e.g., for DCI format 0_1). As another example, the second set of SRS resources for the second set (e.g., for DCI format 0_2) may include the first N SRS resources in the second set of SRS resources for the first set (e.g., for DCI format 0_1).

In some aspects, the first set of SRS resource sets includes two SRS resource sets and the second set of SRS resource sets includes two SRS resource sets. In this case, the mobile station may be configured for multi-TRP uplink communication for both the first DCI format and the second DCI format (e.g., 0_1 and 0_2, respectively). In some aspects, the first set or the second set may include two SRS resource sets, and the other set may include only one SRS resource set. In this case, the mobile station may be configured for multi-TRP uplink communication only for DCI formats associated with two SRS resource sets and configured for single TRP uplink communication for another DCI format associated with one SRS resource set.

In some aspects, the configuration information indicates: the first DCI format is associated with a first dynamic switching field and the second DCI format is associated with a second dynamic switching field. The dynamic handover field may be a two-bit field for indicating which TRP(s) the mobile station is to transmit uplink communications (e.g., PUSCH repetition). For example, in the case that the mobile station is configured with multiple SRS resource sets for DCI formats, the dynamic handover bit may indicate: the mobile station is to send PUSCH repetitions to only the first TRP (e.g., mapped to 00), to only the second TRP (e.g., mapped to 01), to both TRPs (where the repetition for the first TRP precedes the repetition for the second TRP (e.g., mapped to 10)), or to both TRPs (where the repetition for the second TRP precedes the repetition for the first TRP (e.g., mapped to 11)).

In some aspects, the configuration information indicates at least one rule specifying an order in which PUSCH communications are to be transmitted, the order based at least in part on the received DCI format. In some cases, the dynamic handover field may not be configured for a DCI format, but two SRS resource sets may be configured for a DCI format. Without dynamic switching to indicate which SRS resource sets are to be used first for PUSCH repetition, at least one rule may address which SRS resource sets are to be used. For example, PUSCH repetition scheduled with a DCI format may be associated with an SRS resource set with the lowest SRS resource set identifier (e.g., assuming code point 00 of the dynamic handover field) among two SRS resource sets configured for the DCI format. As another example, PUSCH repetition scheduled with a DCI format may be associated with two SRS resource sets, and the SRS resource set with the lowest SRS resource set identifier of the two SRS resource sets configured for the DCI format is first (e.g., assuming code point 10 of the dynamic handover field).

In some aspects, the order specified by the rules may be based at least in part on the presence of dynamic switching fields in the received DCI. For example, where two SRS resource sets are configured for a DCI format, the dynamic handover field may be configured for a DCI format (e.g., as described herein). In the case where only one SRS resource set is configured for a DCI format, the dynamic handover field is not configured for a DCI format (e.g., no handover between TRPs is required).

In some aspects, the configuration information may indicate that the base station may transmit DCI with one of two different formats for scheduling uplink transmissions (e.g., formats 0_1 and 0_2 for scheduling PUSCH repetition) to the mobile station. In some aspects, the SRS resource sets described herein may have a use value that indicates that the SRS resource set is a codebook or a non-codebook SRS resource set.

As indicated by reference numeral 810, a mobile station may configure the mobile station for communication with a base station. In some aspects, the mobile station may configure the mobile station based at least in part on the configuration information. In some aspects, a mobile station may be configured to perform one or more of the operations described herein. For example, the mobile station may be configured to transmit at least one uplink communication using the first set or the second set of SRS resources based at least in part on the received DCI format being the first DCI format or the second DCI format.

As shown by reference numeral 815, the base station may transmit DCI and the mobile station may receive the DCI. For example, the DCI may be transmitted via a PDCCH and may be one of two DCI formats (e.g., DCI format 0_1 or 0_2) for scheduling uplink communications from a mobile station. In some aspects, the DCI may include a dynamic handover field indicating an order in which PUSCH repetition is to be transmitted. For example, the dynamic handover field may include two bits indicating which of the plurality of TRPs should be the recipient of the first PUSCH repetition transmitted by the mobile station.

As indicated by reference numeral 820, the mobile station can select at least one SRS resource for at least one uplink communication. The at least one SRS resource may be selected based at least in part on a format of the received DCI. For example, as described herein, when a mobile station receives DCI of a first DCI format (e.g., DCI format 0_1), the mobile station may select at least one SRS resource from a set of SRS resources configured for the first DCI format. When the mobile station receives DCI of a second DCI format (e.g., DCI format 0_2), the mobile station may select at least one SRS resource from a set of SRS resources configured for the second DCI format.

As indicated by reference numeral 825, the mobile station can schedule PUSCH repetition. In some aspects, PUSCH repetition may be scheduled for transmission using at least two SRS resource sets. For example, the received DCI scheduling PUSCH repetition may be a DCI format for which a plurality of SRS resource sets (e.g., multi-TRP configured) are configured. In some aspects, when the dynamic handover field is configured for DCI and present, PUSCH repetition may be scheduled based at least in part on the value of the dynamic handover field. For example, as described herein, the value of the dynamic handover field may indicate the order in which the mobile station is to schedule PUSCH repetitions between multiple TRPs. In some aspects, the mobile station may schedule PUSCH repetition using a preconfigured rule, as described herein. For example, the mobile station may schedule PUSCH repetitions such that the SRS resource set with the lowest SRS resource set identifier is associated with a first PUSCH repetition for a first TRP and another SRS resource set is associated with a second PUSCH repetition for a second TRP.

In some aspects, as described herein, the first SRS resource set (e.g., based on the SRS resource set identifier) configured for the second DCI format (e.g., DCI format 0_2) may include the first N SRS resources in the first SRS resource set or the second SRS resource set configured for the first DCI format (e.g., DCI format 0_1). Similarly, the second set of SRS resources configured for the second DCI format may include the first N SRS resources in the first or second set of SRS resources configured for the first DCI format. For example, in the case where two SRS resource sets are configured for both DCI format 0_1 and DCI format 0_2, a first SRS resource set for DCI format 0_2 may be configured to include the first N resources of the first SRS resource set configured for DCI format 0_1 and a second SRS resource set for DCI format 0_2 may be configured to include the first N resources of the second SRS resource set configured for DCI format 0_1. In the case where one SRS resource set is configured for DCI format 0_1 and two SRS resource sets are configured for DCI format 0_2, at least one of the first SRS resource set or the second SRS resource set for DCI format 0_2 may be configured to include the first N resources of the SRS resource set configured for DCI format 0_1. In the case where two SRS resource sets are configured for DCI format 0_1 and one SRS resource set is configured for DCI format 0_2, the SRS resource set for DCI format 0_2 may be configured to include the first N resources in the first SRS resource set or the second SRS resource set configured for DCI format 0_1. As described herein, using the same SRS resources in the second DCI format may reduce the complexity of the mobile station when transmitting PUSCH repetition by reducing the number of different parameters associated with different SRS resources.

As indicated by reference numeral 830, a mobile station may transmit and a base station may receive at least one uplink communication. For example, at least one uplink communication may be transmitted using (e.g., based at least in part on the configuration information) at least one SRS resource of the at least one SRS resource set configured for the first DCI format or the second DCI format. In some aspects, the uplink communication may include one or more PUSCH repetitions, as described herein. In some aspects, one PUSCH repetition set may be transmitted to one base station (e.g., a TRP located at a base station), while another PUSCH repetition set may be transmitted to another base station (e.g., another TRP located at the same base station or a different base station). As described herein, the order in which PUSCH repetitions are transmitted is based on the manner in which PUSCH repetitions are scheduled.

As indicated above, fig. 8 is provided as an example. Other examples may be different than described with respect to fig. 8.

Fig. 9 is a diagram illustrating an example 900 associated with uplink communications configured for different SRS resource sets in accordance with the disclosure. As shown in fig. 9, the configuration of two SRS resource sets for DCI format 0_1 (e.g., on the left side of example 900) and two SRS resource sets for DCI format 0_2 (e.g., on the left side of example 900) are shown. Example 900 depicts a case in which SRS resource set usage is set to a codebook.

For DCI format 0_1, the first SRS resource set has SRS resource identifier 2 and includes four SRS resources (e.g., labeled SRS resources 0-3). The second set of SRS resources has SRS resource identifier 4 and includes three SRS resources (e.g., labeled SRS resources 4-6). For DCI format 0_2, the first SRS resource set has SRS resource identifier 3 and includes two SRS resources (e.g., the first N SRS resources in the first SRS resource set for DCI format 0_1, labeled SRS resources 0-1). The second set of SRS resources has SRS resource identifier 5 and includes one SRS resource (e.g., the first N SRS resources in the second set of SRS resources for DCI format 0_1, labeled SRS resource 4).

In example 900, to order the multi-TRP PUSCH transmissions, the first and second SRS resource sets are SRS resource sets 2 and 4 for DCI format 0_1, respectively, and SRS resource sets 3 and 5 for DCI format 0_2, respectively. While the dynamic handover field of the DCI may indicate a different order in which SRS resource sets should be transmitted in the PUSCH repetition, the first SRS resource set and the second SRS resource set of each DCI format may be based on SRS resource identifiers (e.g., the lowest SRS resource set identifier is first) as described herein.

As indicated above, fig. 9 is provided as an example. Other examples may differ from that described with respect to fig. 9.

Fig. 10 is a schematic diagram illustrating an example process 1000 performed, for example, by a mobile station, in accordance with the present disclosure. Example process 1000 is an example of a mobile station (e.g., UE 120) performing operations associated with communications associated with different sets of sounding reference signal resources.

For example, a mobile station (e.g., using communication manager 140 and/or receiving component 1202 depicted in fig. 12) can receive configuration information indicating a plurality of SRS resource sets, the configuration information indicating: a first set of SRS resource sets of the plurality of SRS resource sets associated with the first DCI format, and a second set of SRS resource sets of the plurality of SRS resource sets associated with the second DCI format, wherein at least one of the first set or the second set comprises at least two of the plurality of SRS resource sets, as described above.

While fig. 10 shows example blocks of process 1000, in some aspects process 1000 may include additional blocks, fewer blocks, different blocks, or blocks arranged in a different manner than the blocks depicted in fig. 10. Additionally or alternatively, two or more of the blocks of process 1000 may be performed in parallel.

Fig. 11 is a diagram illustrating an example process 1100 performed, for example, by a base station, in accordance with the present disclosure. Example process 1100 is an example of a base station (e.g., base station 110) performing operations associated with communication associated with different sets of sounding reference signal resources.

Process 1100 may include additional aspects, such as any single aspect or any combination of aspects described below and/or in conjunction with one or more other processes described elsewhere herein.

In a first aspect, the configuration information indicates: the mobile station is to transmit at least one uplink communication using the first set or the second set based at least in part on a format of a received DCI having one of the first DCI format or the second DCI format, the received DCI being associated with scheduling the uplink communication.

While fig. 11 shows example blocks of the process 1100, in some aspects the process 1100 may include additional blocks, fewer blocks, different blocks, or blocks arranged in a different manner than the blocks depicted in fig. 11. Additionally or alternatively, two or more of the blocks of process 1100 may be performed in parallel.

Some techniques and apparatuses described herein enable a mobile station to be individually configured to schedule multi-TRP transmissions for different DCI formats without increasing the mobile station complexity involved in determining which SRS resources and/or SRS resource sets are to be used for PUSCH repetition scheduled by the different DCI formats. For example, the mobile station may be configured with a first set of SRS resource sets for a first DCI format (e.g., DCI format 0_1) and a second set of SRS resource sets for a second DCI format (e.g., DCI format 0_2). For example, the second set of SRS resource sets (e.g., for DCI format 0_2) may include the first N SRS resources of the first set of corresponding SRS resource sets (e.g., for DCI format 0_1) and the order in which uplink communications are transmitted may be determined based on the lowest SRS resource set identifier transmitted first. When receiving DCI scheduling uplink communication (e.g., PUSCH repetition), the mobile station may select SRS resources for uplink communication based on a format of the DCI. This may enable the mobile station to schedule PUSCH repetition for multiple DCI formats and for multiple TRPs using the same rule for each DCI format (e.g., lowest SRS resource set identifier first). This may reduce the complexity of the mobile station to process DCI scheduling uplink communications, save resources (e.g., processing resources, power resources, etc.) of the mobile station and enable efficient multi-TRP network communications, which may reduce wireless network congestion and lead to improved communication quality over the wireless network.

Fig. 12 is a schematic diagram of an example apparatus 1200 for wireless communication. The apparatus 1200 may be a UE (e.g., a mobile station), or the UE may include the apparatus 1200. In some aspects, apparatus 1200 includes a receiving component 1202 and a transmitting component 1204 that can communicate with each other (e.g., via one or more buses, and/or one or more other components). As shown, apparatus 1200 may communicate with another apparatus 1206 (such as a UE, a base station, or another wireless communication device) using a receiving component 1202 and a transmitting component 1204. As further shown, apparatus 1200 may include a communication manager 140. The communication manager 140 may include one or more of the following: a configuration component 1208, a selection component 1210, or a scheduling component 1212, etc.

In some aspects, apparatus 1200 may be configured to perform one or more operations described herein in connection with fig. 3-9. Additionally or alternatively, apparatus 1200 may be configured to perform one or more processes described herein, such as process 1000 of fig. 10. In some aspects, the apparatus 1200 and/or one or more components shown in fig. 12 may include one or more components of the UE described in connection with fig. 2. Additionally or alternatively, one or more of the components shown in fig. 12 may be implemented within one or more of the components described in connection with fig. 2. Additionally or alternatively, one or more components of the set of components may be at least partially implemented as software stored in memory. For example, a component (or a portion of a component) may be implemented as instructions or code stored in a non-transitory computer-readable medium and executable by a controller or processor to perform the functions or operations of the component.

The receiving component 1202 can receive communications, such as reference signals, control information, data communications, or a combination thereof, from the apparatus 1206. The receiving component 1202 may provide the received communication to one or more other components of the apparatus 1200. In some aspects, the receiving component 1202 can perform signal processing (such as filtering, amplifying, demodulating, analog-to-digital converting, demultiplexing, deinterleaving, demapping, equalizing, interference cancellation or decoding, etc.) on the received communication and can provide the processed signal to one or more other components of the apparatus 1200. In some aspects, the receiving component 1202 may include one or more antennas, modems, demodulators, MIMO detectors, receive processors, controllers/processors, memory, or a combination thereof of a UE described in connection with fig. 2.

The transmitting component 1204 can transmit a communication, such as a reference signal, control information, data communication, or a combination thereof, to the device 1206. In some aspects, one or more other components of apparatus 1200 may generate a communication and may provide the generated communication to send component 1204 for transmission to apparatus 1206. In some aspects, the transmitting component 1204 can perform signal processing (such as filtering, amplifying, modulating, digital-to-analog converting, multiplexing, interleaving, mapping, encoding, or the like) on the generated communication and can transmit the processed signal to the device 1206.
