Cross Reference to Related Applications

This patent application claims priority from U.S. provisional patent application No.63/168,824 entitled "CONFIGURING SEPARATE POWER CONTROL ADJUSTMENT STATES FOR SOUNDING REFERENCE SIGNAL transmission systems (separate power control adjustment state for sounding reference signal transmission configuration)" filed on month 31 of 2021, and U.S. non-provisional patent application No.17/643,094 entitled "CONFIGURING SEPARATE POWER CONTROL ADJUSTMENT STATES FOR SOUNDING REFERENCE SIGNAL transmission systems (separate power control adjustment state for sounding reference signal transmission configuration)" filed on month 7 of 2021, which are hereby expressly incorporated by reference.

FIELD OF THE DISCLOSURE

Aspects of the present disclosure relate generally to wireless communications and relate to techniques and apparatuses for configuring separate power control adjustment states for Sounding Reference Signal (SRS) transmissions.

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) mobility guidelines promulgated by the third generation partnership project (3 GPP).

A wireless network may include one or more base stations supporting communication for one or more User Equipment (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 telecommunications guidelines 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 guidelines promulgated by 3 GPP. NR is designed to better support mobile broadband internet access by 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 supporting beamforming, multiple Input Multiple Output (MIMO) antenna technology and carrier aggregation to improve spectral efficiency, reduce cost, improve service, utilize new spectrum, and integrate better with other open guidelines. 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 below 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. Those skilled in the art will appreciate that the scope of the disclosure is intended to cover any aspect of the disclosure disclosed herein, whether implemented independently 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.

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 present 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 a 5G (e.g., NR) network and/or a 4G (e.g., long Term Evolution (LTE)) network, etc., or may include elements thereof. Wireless network 100 may include one or more base stations 110 (shown as BS110a, BS110b, BS110c, and BS110 d), one or more User Equipments (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, node BS, enbs (e.g., in 4G), gnbs (e.g., in 5G), access points, and/or Transmission and Reception 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.

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. A picocell 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 associated 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, a cell may not necessarily be stationary, and the geographic area of the cell may move according to the location of a mobile base station 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 transport network.

The wireless network 100 may include one or more relay stations. A relay station is an entity that can receive a transmission of data from an upstream station (e.g., base station 110 or UE 120) and send the transmission of the 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 for 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 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 relay, and so on.

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, or 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 or in communication with a set of base stations 110 and may provide coordination and control of 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.

The UEs 120 may be dispersed throughout the 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 smartband)), an entertainment device (e.g., a music device, a video device, and/or a satellite radio), an in-vehicle component or sensor, a smart meter/sensor, industrial manufacturing equipment, a global positioning system device, or any other suitable device configured to communicate via a wireless medium.

Some UEs 120 may be considered Machine Type Communication (MTC) UEs, or evolved or enhanced machine type communication (eMTC) UEs. MTC UEs and/or eMTC UEs may include, for example, robots, drones, remote devices, sensors, gauges, 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 client devices. UE 120 may be included within a housing that houses components of UE 120, 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. The 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 geographic area 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 (e.g., without using base station 110 as an intermediary to communicate with each other) using one or more side link channels. For example, UE 120 may communicate using peer-to-peer (P2P) communication, device-to-device (D2D) communication, a vehicle-to-vehicle (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 the wireless network 100 may communicate using electromagnetic spectrum that may be subdivided into various categories, bands, channels, etc., by frequency or wavelength. 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 designated 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 (interchangeably) referred to as the "sub-6 GHz" band in various documents and articles. Similar naming problems sometimes occur with respect to FR2, which is commonly (interchangeably) referred to as the "millimeter wave" band in various documents and articles, although it is different from the Extremely High Frequency (EHF) band (30 GHz-300 GHz) identified by the International Telecommunications Union (ITU) as the "millimeter wave" band.

The frequency between FR1 and FR2 is commonly referred to as the mid-band frequency. 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 thus may effectively extend the characteristics of FR1 and/or FR2 into mid-band frequencies. Additionally, higher frequency bands are currently being explored to extend 5G NR operation above 52.6 GHz. For example, three higher operating bands have been identified as frequency range designation 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 should be understood that, if used herein, the term sub-6 GHz and the like may broadly represent frequencies that may be less than 6GHz, may be within FR1, or 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 mean frequencies that may include mid-band frequencies, may be within FR2, FR4-a, or FR4-1 and/or FR5, or 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.

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

Fig. 2 is a diagram illustrating an example 200 in which a base station 110 is in communication with a UE 120 in a wireless network 100 according to 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 group 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(s) selected for UE 120 and may provide data symbols to 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 modulators) (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 further 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 corresponding set of 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 the downlink signals from base station 110 and/or other base stations 110 and may provide a set of received signals (e.g., R received signals) 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 condition (e.g., filter, amplify, downconvert, and/or digitize) a received signal using a corresponding demodulator component to obtain input samples. Each modem 254 may use a demodulator assembly to further process the input samples (e.g., for OFDM) 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 data sink 260, and may provide decoded control information and system information to 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, among others. 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. The network controller 130 may comprise, for example, 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 coplanar antenna element set, a non-coplanar antenna element set, and/or one or more antenna elements coupled to one or more transmission and/or reception components (such as one or more components of fig. 2).

On the uplink, at UE 120, transmit processor 264 may receive and process data from data source 262 and 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 antenna(s) 252, modem(s) 254, MIMO detector 256, receive processor 258, transmit processor 264, and/or TX MIMO processor 266. The transceiver may be used by a processor (e.g., controller/processor 280) and memory 282 to perform aspects of any of the methods described herein (e.g., with reference to fig. 4-8).

At base station 110, uplink signals from UE 120 and/or 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 sent 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 antenna(s) 234, modem(s) 232, MIMO detector 236, receive processor 238, transmit processor 220, and/or TX MIMO processor 230. The transceiver may be used by a processor (e.g., controller/processor 240) and memory 242 to perform aspects of any of the methods described herein (e.g., with reference to fig. 4-8).

The controller/processor 240 of the base station 110, the controller/processor 280 of the UE 120, and/or any other component(s) of fig. 2 may perform one or more techniques associated with configuring separate power control adjustment states for Sounding Reference Signal (SRS) transmission, as described in more detail elsewhere herein. For example, controller/processor 240 of base station 110, controller/processor 280 of UE 120, and/or any other component(s) of fig. 2 may perform or direct operations such as process 700 of fig. 7, process 800 of fig. 8, and/or other processes as described herein. Memory 242 and memory 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 700 of fig. 7, process 800 of fig. 8, and/or other processes described herein. In some examples, executing instructions may include executing instructions, converting instructions, compiling instructions, and/or interpreting instructions, among others.

In some aspects, a UE (e.g., UE 120) includes: means for receiving an uplink power control configuration for a set of SRS resources associated with an uplink component carrier from a base station, wherein the uplink power control configuration configures a separate power control adjustment state between SRS transmissions and Physical Uplink Shared Channel (PUSCH) transmissions, and wherein the uplink power control configuration indicates one of a first SRS power control adjustment state or a second SRS power control adjustment state; and/or means for transmitting SRS to the base station based at least in part on the uplink power control configuration for the set of SRS resources. Means for a UE to perform the operations described herein may include, for example, one or more of the antennas 252, the demodulator 254, the MIMO detector 256, the receive processor 258, the transmit processor 264, the TX MIMO processor 266, the modulator 254, the controller/processor 280, or the memory 282.

In some aspects, a base station comprises: means for transmitting, to the UE, an uplink power control configuration for a set of SRS resources associated with the uplink component carrier, wherein the uplink power control configuration configures a separate power control adjustment state between the SRS transmission and the PUSCH transmission, and wherein the uplink power control configuration indicates one of the first SRS power control adjustment state or the second SRS power control adjustment state; and/or means for receiving SRS from the UE based at least in part on the uplink power control configuration for the set of SRS resources. Means for a base station to perform the operations described herein can include, for example, one or more of the transmit processor 220, the TX MIMO processor 230, the modulator 232, the antenna 234, the demodulator 232, the MIMO detector 236, the receive processor 238, the controller/processor 240, the memory 242, or the scheduler 246.

Although the blocks in fig. 2 are illustrated as distinct components, the functionality described above with respect to the blocks may be implemented in a single hardware, software, or combination of components or a combination of various 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 indicated above, fig. 2 is provided as an example. Other examples may differ from the example described with respect to fig. 2.

The uplink power control may determine the power for SRS transmission.

When the UE transmits SRS on the active Uplink (UL) bandwidth portion (BWP) b of carrier f of serving cell c based on an SRS power control adjustment state with index l through configuration of SRS resource set (SRS-resource set), the UE may determine SRS transmission power (in dBm) in SRS transmission opportunity as: wherein the active UL BWP b and SRS resource set q for carrier f of serving cell c _s ，P _{O_SRS,b,f,c} (q _s ) From p ₀ (e.g., values ranging from-202 to 24), SRS resource set q _s Provided by SRS-resource set and SRS resource set identification (SRS-resource set Id)) and for active UL BWP b and SRS resource set q of carrier f serving cell c _s ，α _SRS,b,f,c (q _s ) Provided by α. Furthermore, PL _b,f,c (q _d ) Is to use the Reference Signal (RS) resource index and SRS resource set q for the active UL BWP b of the serving cell c by the UE _s A calculated downlink path loss estimate (in dB). RS resource index q _d Can be combined with SRS resource set q _s An associated set of path loss reference resources (path loss reference RS (pathlossReferenceRS)).

For the SRS power control adjustment state for the active UL BWPb of carrier f of serving cell c and SRS transmission occasion i, if the SRS power control adjustment state parameter (SRS-power control adjustment state (SRS-powercontrol adjustment states)) indicates the same power control adjustment state for SRS transmission and PUSCH transmission, h _b,f,c (i，l)＝f _b，f，c (i, l) wherein f _b，f，c (i, l) is the current PUSCH power control adjustment state, or if atThe UE on active UL BWPb of carrier f of serving cell c is not configured for PUSCH transmission, or if SRS-power control adjustment state indicates a separate power control adjustment state between SRS transmission and PUSCH transmission, and if tpc-accounting (tpc-Accumulation) is not provided, h _b,f,c (i)＝h _b，f，c (i-i ₀ )+∑ _m＝0 δ _{SRS，b，f，c} (m) wherein delta _{SRS，b，f，c} (m) decoding in conjunction with other Transmit Power Control (TPC) commands in the Physical Downlink Control Channel (PDCCH) using DCI format 23.

The configuration per SRS resource set may include α, p ₀ A pathloss reference RS parameter, and a srs-power control adjustment status parameter, which may be associated with a separate closed loop (seperatecosetloop) parameter. Further, SRS-power control adjustment state parameter may indicate the same adjustment state for SRS and PUSCH (and if the same, l=0, 1 for the first or second adjustment state) or separate adjustment states for SRS. In addition, h _b，c，f (i, l) may indicate a closed loop power control adjustment state, where l=0 or 1. For h _b，c，f (i) In the case of separate adjustment states for SRS, only one closed loop index (one adjustment state) may be defined for SRS. In other words, there is no l in the function h (). In the case of separate adjustment states for SRS, TPC commands may be indicated in DCI format 23.

DCI format 23 may be applicable to UL Component Carriers (CCs) in a case where PUSCH is not configured (e.g., for SRS carrier switching) or independent power control between SRS and PUSCH. The DCI format 23 may be a group-shared DCI with a Cyclic Redundancy Check (CRC) scrambled using a TPC SRS radio network temporary identifier (TPC-SRS-RNTI), where the DCI format 23 may contain a plurality of blocks and a start position of the blocks may be configured per UE. The payload/field of a block may be based at least in part on whether the SRS request field is included. The SRS request field may optionally be configured by a "fieldTypeFormat2-3 (field type format 2-3)" Radio Resource Control (RRC) parameter, which may be two bits if configured. The payload/field of a block may be based at least in part on whether the block is associated with type a or type B, which may be configured using SRS TPC PDCCH Group (srs-TPC-PDCCH-Group (srs-TPC-PDCCH-Group)) parameters. For type B, each block may include an SRS request field (0 or 2 bits) and a TPC command field (2 bits). The UE may be configured with multiple blocks for different uplink component carriers. For type a, each block may include an SRS request field (0 or 2 bits) and N TPC command fields (2*N bits) corresponding to different uplink component carriers, and only one block may be configured for the UE.

The C command field value of 0 may correspond to accumulated delta _SRS,b,f,c ，δ _SRS,b,f,c The tpc command field value 1 may correspond to the accumulated delta with a value of-1 db _SRS,b,f,c ，δ _SRS,b,f,c The tpc command field value 2 may correspond to the accumulated delta with a value of 0db _sRs,b,f,c ，δ _sRs,b,f,c Is 1dB, or the TPC command field value 3 may correspond to the accumulated delta _SRS,b,f,c ，δ _{SRS，b，f，c} The value of (2) is 3dB.

Fig. 3 is a diagram illustrating an example 300 of a DCI format according to the present disclosure.

As shown by reference numeral 302, the DCI format 2_3 may include B blocks, and a start position of a block (e.g., block number 2) may be configured for a certain UE. The block in DCI format 2_3 may be a type B block or a type a block. As shown by reference numeral 304, the type B block may include an SRS request field (0 or 2 bits) and a TPC command field (2 bits). Type B blocks may be used for a given uplink component carrier. As shown by reference numeral 306, the type a block may include an SRS request field (0 or 2 bits) and N TPC command fields (2*N bits).

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

The SRS requests may differ between type a blocks and type B blocks. For a type B block, the mapping between SRS resource sets and SRS request code points (e.g., 01, 10, or 11) may be given as part of an aperiodic SRS resource trigger (aperiodic SRS-resource trigger) parameter or an aperiodic SRS resource trigger list (aperiodic SRS-resource trigger list) parameter (as part of SRS resource set configuration). For type a blocks, aperiodic SRS may be triggered for a CC set. Three CC sets may map to three codepoints (e.g., 01, 10, and 11), and CCs may belong to one or more CC sets. When SRS is triggered for a set of CCs, a set of aperiodic SRS resources configured with usage of antenna switching (e.g., usage= 'antenna switching') in each CC in the set of CCs may be triggered.

When the value of the SRS request field is '01' and the SRS-TPC-PDCCH-group higher layer parameter is set to 'type B (typeB)', the SRS resource set(s) may be configured by an SRS-resource set with the higher layer parameter aperiodic SRS-resource trigger set to 1 or the entry in the aperiodic SRS-resource trigger list set to 1. When the value of the SRS request field is '10' and the SRS-TPC-PDCCH-group higher layer parameter(s) is set to 'type B', the SRS resource set(s) may be configured by SRS-resource set with the higher layer parameter aperiodic SRS-resource trigger set to 2 or the entry in the aperiodic SRS-resource trigger list set to 2. When the value of the SRS request field is '11' and the SRS-TPC-PDCCH-group higher layer parameter(s) is set to 'type B', the SRS resource set(s) may be configured by SRS-resource set with the higher layer parameter aperiodic SRS-resource trigger set to 3 or the entry in the aperiodic SRS-resource trigger list set to 3.

When the value of the SRS request field is '01' and the SRS-TPC-PDCCH-group higher layer parameter is set to 'type a (typeA)', for the first serving cell set configured by the higher layer, the SRS resource set(s) may be configured with the higher layer parameter usage in the SRS-ResourceSet set to 'antenna switch' and the higher layer parameter resourceType in the SRS-ResourceSet set to 'aperiodic'. When the value of the SRS request field is '10' and the SRS-TPC-PDCCH-group higher layer parameter is set to 'type a', for the second set of serving cells configured by the higher layer, the SRS resource set(s) may be configured with the higher layer parameter usage in SRS-resource set to 'antenna switch' and the higher layer parameter resourceType in SRS-resource set to 'aperiodic'. When the value of the SRS request field is '11' and the SRS-TPC-PDCCH-group higher layer parameter is set to 'type a', for the third serving cell set configured by the higher layer, the SRS resource set(s) may be configured with the higher layer parameter usage in SRS-resource set to 'antenna switch' and the higher layer parameter resourceType in SRS-resource set to 'aperiodic'.

Different SRS resource sets may be transmitted using different UL beams (e.g., different spatial relationships and/or UL Transmission Configuration Indicator (TCI) states) or different UE panels, and different SRS resource sets may be received by different TRPs. Thus, it may be useful to have different power control adjustment states for SRS. However, SRS power control independent of PUSCH power control with respect to closed loop power control adjustment states, while allowing two separate closed loop adjustment states for SRS only is not currently supported.

In various aspects of the techniques and apparatuses described herein, a UE may receive an uplink power control configuration from a base station for a set of SRS resources associated with an uplink component carrier. Uplink power control configuration may configure separate power control adjustment states between SRS transmission and PUSCH transmission. The uplink power control configuration may indicate a first SRS power control adjustment state or a second SRS power control adjustment state. The first SRS power control adjustment state may be associated with a first closed loop index (e.g., l=0) and the second SRS power control adjustment state may be associated with a second closed loop index (e.g., l=1).

In previous solutions, two closed loop adjustment states might be possible for SRS only when the closed loop power control adjustment state is shared with PUSCH and when PUSCH is configured with two PUSCH power control adjustment states (twofpusch-PC-adjustment states).

In some cases, using the same closed loop adjustment state as PUSCH may cause problems, so it may be advantageous for SRS to have separate power control from PUSCH. For example, when the uplink component carrier is configured with PUSCH transmissions, the interference management and interference profile may have different behavior and properties for SRS resources relative to PUSCH resources. Further, SRS transmissions may not be precoded (e.g., for codebook-based PUSCH purposes), whereas PUSCH transmissions are typically precoded, and the target signal-to-interference-plus-noise ratio (SINR) may be different between PUSCH and SRS. Furthermore, the receiver for SRS detection/estimation may have different properties (e.g., accuracy requirements) than the receiver for PUSCH decoding. Different properties may be associated with different UL target block error rate (BLER) requirements. Further, in some cases, the uplink component carrier may not be configured with PUSCH transmissions. For example, for DL Channel State Information (CSI) acquisition purposes, only SRS may be transmitted in the uplink component carrier, and the use of SRS resource sets may be 'antenna switching'. Thus, SRS has two separate closed loop adjustment states and it may be advantageous for SRS to be separated from the power control of PUSCH.

Fig. 4 is a diagram illustrating an example 400 associated with a separate power control adjustment state for SRS transmission configuration in accordance with the present disclosure. As shown in fig. 4, example 400 includes communication between a UE (e.g., UE 120) and a base station (e.g., base station 110). In some aspects, the UE and the base station may be included in a wireless network (such as wireless network 100).

As shown at reference numeral 402, the UE may receive an uplink power control configuration for a set of SRS resources associated with an uplink component carrier from the base station. The uplink power control configuration may configure separate power control adjustment states between SRS transmission and PUSCH transmission. The uplink power control configuration may indicate a first SRS power control adjustment state or a second SRS power control adjustment state. In some aspects, a first SRS power control adjustment state may be associated with a first closed loop index (e.g., l=0) and a second SRS power control adjustment state may be associated with a second closed loop index (e.g., l=1). In some aspects, the first SRS power control adjustment state and the second SRS power control adjustment state may be configured for an uplink component carrier associated with the SRS resource set.

In some aspects, the SRS resource set may be associated with a first power control adjustment state shared between SRS and PUSCH, wherein the first power control adjustment state may be associated with a first closed loop index. Alternatively, the SRS resource set may be associated with a second power control adjustment state shared between SRS and PUSCH, wherein the second power control adjustment state may be associated with a second closed loop index. Alternatively, the SRS resource set may be associated with a third power control adjustment state corresponding to the first SRS power control adjustment state that may be separate for SRS and PUSCH, wherein the third power control adjustment state may be associated with the first closed loop index. Alternatively, the SRS resource set may be associated with a fourth power control adjustment state corresponding to the second SRS power control adjustment state that may be separate for SRS and PUSCH, wherein the fourth power control adjustment state is associated with the second closed loop index.

In some aspects, each SRS resource set may be configured with a separate power control adjustment state between SRS transmission and PUSCH transmission and with one of two closed loop indices l=0 or l=1 corresponding to one of the two separate power control adjustment states. The power control adjustment state configured for the SRS resource set may be one of four possibilities. For example, the power control adjustment state of the SRS resource set may be the same as PUSCH, where l=0, the power control adjustment state of the SRS resource set may be the same as PUSCH, where l=1, the power control adjustment state of the SRS resource set may be separate from PUSCH, where l=0, or the power control adjustment state of the SRS resource set may be separate from PUSCH, where l=1.

In some aspects, the UE may transmit UE capability signaling to the base station indicating that the UE supports a power control adjustment state that is split between SRS transmission and PUSCH transmission. The UE may support separating the first SRS power control adjustment state and the second SRS power control adjustment state from PUSCH power control. The UE may receive the uplink power control configuration from the base station based at least in part on the UE capability signaling.

In some aspects, a power control adjustment state for the SRS resource set separate from PUSCH, where l=1, may be based at least in part on the UE indicating support for two closed loops for SRS power control separate from PUSCH power control. The UE may indicate the support to the base station via the UE capability signaling. The base station may configure two SRS power control adjustment state (two SRS-PC-adjustment states) parameters for the uplink component carrier in which the SRS resource set is configured based at least in part on the capability signaling.

In some aspects, when the UE is configured with TPC accumulation (TPC-accumulation) parameters for SRS, or when the UE is not configured with TPC-accumulation parameters, the UE may maintain two closed loop adjustment states for SRS transmission in a given uplink component carrier because lack of TPC-accumulation parameters results in TPC accumulation being enabled. Further, when a UE is configured with two SRS-PC-adjustment status parameters, the UE may maintain two closed loop adjustment status for SRS transmission in a given uplink component carrier. In some aspects, the tpc-accumulation parameter and the two SRS-PC-adjustment state parameters may be configured using an SRS configuration common to multiple SRS resource sets (e.g., all SRS resource sets) in a given uplink component carrier.

In some aspects, the UE may maintain a first SRS power control adjustment state and a second SRS power control adjustment state for SRS transmissions in the uplink component carrier based at least in part on the tpc-accumulation parameter and the two SRS-PC-adjustment state parameters. The UE may receive the tpc-accumulation parameter and the two SRS-PC-adjustment state parameters from the base station via an SRS configuration common to a plurality of SRS resource sets associated with the uplink component carrier.

In some aspects, for SRS power control adjustment state l, h of the closed loop power control adjustment state may be indicated _b,c,f (i, l) can conform tol=0, 1, where h _b,c,f (i-i ₀ L) can be associated with SRS transmission occasions i-i for adjusting the state to l ₀ Is associated with the accumulated TPC commands of (c), andcan be matched with the self-transmission time i-i ₀ The sum of the new TPC command values (in DCI format 2_3) is associated.

In some aspects, when an uplink component carrier is configured with both a first SRS power control adjustment state and a second SRS power control adjustment state for SRS power control, the UE may receive DCI (e.g., DCI format 2_3) from the base station indicating whether TPC commands for the uplink component carrier correspond to the first SRS power control adjustment state or the second SRS power control adjustment state.

In some aspects, the DCI may include a first type of block associated with an uplink component carrier. In some aspects, the block may include a bit appended to the TPC field to indicate whether the TPC command associated with the TPC field corresponds to a first SRS power control adjustment state or a second SRS power control adjustment state. In some aspects, the block may include a first TPC field corresponding to a first SRS power control adjustment state and a second TPC field corresponding to a second SRS power control adjustment state. In some aspects, the block may include a TPC field having TPC commands associated with the first SRS power control adjustment state or the second SRS power control adjustment state based at least in part on the triggered SRS resource set indicated by the DCI. In some aspects, the TPC command may be applied to a first SRS power control adjustment state when the triggered SRS resource set in the uplink component carrier is configured with the first SRS power control adjustment state or to a second SRS power control adjustment state when the triggered SRS resource set in the uplink component carrier is configured with the second SRS power control adjustment state.

In some aspects, the TPC command may be applied to the first SRS power control adjustment state and/or the second SRS power control adjustment state according to a fixed rule when a first portion of the set of triggered SRS resources in the uplink component carrier is configured with the first SRS power control adjustment state and a second portion of the set of triggered SRS resources in the uplink component carrier is configured with the second SRS power control adjustment state. In some aspects, the fixed rule may indicate that the TPC command is applied to the first SRS power control adjustment state. In some aspects, the fixed rule may indicate that the TPC command is applied to one of a first SRS power control adjustment state or a second SRS power control adjustment state configured for an SRS resource set having a lowest identifier or a highest identifier among the triggered SRS resource sets. In some aspects, the fixed rule may indicate that the TPC command is applied to both the first SRS power control adjustment state and the second SRS power control adjustment state. In some aspects, the DCI may indicate the TPC command based at least in part on a radio resource control configuration or based at least in part on a function of an SRS resource set configuration or an SRS request field configuration.

In some aspects, the DCI may include a block indicating a second type of TPC command for a plurality of uplink component carriers. In some aspects, the block may include one common bit to indicate whether a plurality of TPC commands corresponding to a plurality of uplink component carriers are associated with a first SRS power control adjustment state or a second SRS power control adjustment state. In some aspects, the block may include a bit for each TPC field to indicate whether the TPC command associated with the TPC field corresponds to a first SRS power control adjustment state or a second SRS power control adjustment state.

In some aspects, the block may include a bit for TPC commands associated with an uplink component carrier of the plurality of uplink component carriers configured with both a first SRS power control adjustment state and a second SRS power control adjustment state for SRS power control, the bit may indicate whether the TPC commands associated with the TPC field correspond to the first SRS power control adjustment state or the second SRS power control adjustment state. In some aspects, the block may include a plurality of TPC fields corresponding to a plurality of uplink component carriers and to a first SRS power control adjustment state, and the block may include a plurality of additional TPC fields corresponding to a plurality of uplink component carriers and to a second SRS power control adjustment state.

In some aspects, the block may include a plurality of TPC fields corresponding to a plurality of uplink component carriers and to the first SRS power control adjustment state. The block may include an additional TPC field having additional TPC commands for an uplink component carrier of the plurality of uplink component carriers configured with both a first SRS power control adjustment state and a second SRS power control adjustment state for SRS power control. The additional TPC commands may be associated with a second SRS power control adjustment state.

As indicated by reference numeral 404, the UE can transmit SRS to the base station based at least in part on the uplink power control configuration for the set of SRS resources. The UE may transmit the SRS using SRS resources associated with the set of SRS resources. The UE may apply uplink power control to SRS transmission based at least in part on the uplink power control configuration for the SRS resource set.

As indicated above, fig. 4 is provided as an example. Other examples may differ from the example described with respect to fig. 4.

Fig. 5 is a diagram illustrating an example 500 associated with a separate power control adjustment state for SRS transmission configuration according to the disclosure.

As shown by reference numeral 502, DCI format 2_3 may include B blocks, and a starting position of a block (e.g., block number 2) may be configured for a certain UE for a given uplink component carrier. DCI format 2_3 may include a type B block. The type B block may be set to type B based at least in part on srs-TPC-PDCCH-Group (rs-TPC-PDCCH Group) parameters and the type B block may be associated with the uplink component carrier.

When the uplink component carrier is configured with two adjustment states (two SRS-PC-adjustment states) for SRS power control, DCI format 2_3 may indicate whether the TPC command for the uplink component carrier corresponds to a first SRS power control adjustment state or a second SRS power control adjustment state (e.g., index l=0 or l=1). In other words, l=0 may be associated with a first SRS power control adjustment state and l=1 may be associated with a second SRS power control adjustment state.

As indicated by reference numeral 504, in a first option, the type B block associated with the uplink carrier may include a bit appended to the TPC field to indicate whether the TPC command corresponds to an SRS power control adjustment state of index l=0 or index l=1. The TPC command may be changed to 3 bits.

As indicated by reference numeral 506, in a second option, the type B block associated with the uplink component carrier may include two TPC fields (2 bits each). The two TPC fields may correspond to a first SRS power control adjustment state of index l=0 and a second SRS power control adjustment state of index l=1, respectively. In this case, the presence of the SRS request field may trigger multiple SRS resource sets, some of which are associated with a first SRS power control adjustment state for index l=0 and others of which are associated with a second SRS power control adjustment state for index l=1.

As indicated by reference numeral 506, in a second option, the type B block associated with the uplink component carrier may include two TPC fields (2 bits each). The two TPC fields may correspond to a first SRS power control adjustment state of index l=0 and a second SRS power control adjustment state of index l=1, respectively. In this case, the presence of the SRS request field may trigger multiple SRS resource sets, some of which are associated with a first SRS power control adjustment state for index l=0 and others of which are associated with a second SRS power control adjustment state for index l=1. As indicated by reference numeral 508, in a third option, the type B block associated with the uplink component carrier may include one TPC field having 2 bits, and whether the TPC field applies to the first SRS power control adjustment state for index l=0 or the second SRS power control adjustment state for index l=1 may depend on the triggered SRS resource set. In other words, whether TPC commands in the TPC field are applied to l=0 or=1 may be based at least in part on the SRS request field, which may be present in DCI format 2_3.

In some aspects, when a plurality of triggered SRS resource sets in the uplink component carrier (e.g., all triggered SRS resource sets mapped to the indicated code point of the SRS request field) are configured to l=0, TPC commands may be applied to the first SRS power control adjustment state of index l=0. In some aspects, when a plurality of triggered SRS resource sets in the uplink component carrier (e.g., all triggered SRS resource sets mapped to the indicated code point of the SRS request field) are configured to l=1, the TPC command may be applied to the first SRS power control adjustment state of index l=1.

In some aspects, the fixed rule may be applied when some of the triggered SRS resource sets in the uplink component carrier are configured to l=0 and other triggered SRS resource sets in the uplink component carrier are configured to l=1. For example, the TPC command may be applied to l=0 (e.g., the first SRS power control adjustment state), or the TPC command may be applied to an adjustment state l configured for the SRS resource set having the lowest/highest ID among the triggered SRS resource sets, or the TPC command may be applied to both l=0 and l=1 (e.g., both the first and second SRS power control adjustment states).

In some aspects, the first option, the second option, or the third option may be RRC configured for DCI format 2_3 or may be a function of SRS resource set configuration or SRS request field configuration. For example, when the SRS request field is not configured (or not present) for DCI format 2_3, the first option or the second option may be employed. The first option or the second option may be employed when an SRS request field is configured (or exists) for DCI format 2_3 and at least one SRS request code point (e.g., 01, 10, or 11) is mapped to two SRS resource sets configured with different power control adjustment states. A third option may be employed when an SRS request field is configured (or present) for DCI format 2_3 and all SRS resource sets mapped to the same SRS request code point (e.g., 01, 10, or 11) are configured with the same power control adjustment state.

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

Fig. 6 is a diagram illustrating an example 600 associated with power control adjustment states separate from configuration for SRS transmission according to the disclosure.

As shown by reference numeral 602, the DCI format 2_3 may include B blocks, and a start position of a block (e.g., block number 2) may be configured for a certain UE. DCI format 2_3 may include a type a block. The type a block may be set to type a based at least in part on the srs-TPC-PDCCH-Group parameter and the type a block may indicate TPC commands for the N uplink component carriers.

As indicated by reference numeral 604, in a first option, the type a block may include one common bit to indicate whether TPC commands 1,2, …, N corresponds to l=0 or l=1. In other words, depending on the value of the one common bit, all TPC commands in a type a block may correspond to a first SRS power control adjustment state of index l=0, or all TPC commands in a type a block may correspond to a second SRS power control adjustment state of index l=1. In addition, 1+2×n bits may correspond to TPC related information in the type a block. The one bit may be applicable only to uplink component carriers configured with two adjustment states (two SRS-PC-adjustment states) for SRS power control.

In some aspects, the type a block may include one bit specific to each TPC field 1,2, …, N to indicate whether each TPC command corresponds to l=0 or l=1. In this case, 3*N bits may correspond to TPC related information in the type a block.

As indicated by reference numeral 606, in the second option, an additional bit to indicate whether TPC commands 1,2, …, N corresponds to l=0 or l=1 is added only for TPC commands associated with uplink component carriers configured with two SRS adjustment states for SRS power control. In other words, some TPC commands may have associated bits to indicate whether the TPC command corresponds to l=0 or l=1, while other TPC commands may not have associated bits.
