[0015] In some examples of the method, UEs, and non-transitory computer-readable medium described herein, based on the PUSCH transmission including the first set of analog CSI, a transmit power spectral density (PSD) for the PUSCH transmission may be based on one or more channel coefficients included in the first set of analog CSI.
[0016] In some examples of the method, UEs, and non-transitory computer-readable medium described herein, the transmit PSD for the PUSCH transmission may be based on a comparison between an error threshold and a quantization error associated with quantizing the first set of analog CSI; or the transmit PSD for the PUSCH transmission may be based on a difference in power between a largest channel coefficient included in the first set of analog CSI and a smallest channel coefficient included in the first set of analog CSI.
[0017] Some examples of the method, UEs, and non-transitory computer-readable medium described herein may further include operations, features, means, or instructions for determining, based on the PUSCH transmission including the first set of analog CSI, a dynamic offset using an iteration loop that may be based on a block error rate associated with decoding a physical downlink shared channel message that corresponds to the analog CSI, where the transmit power may be based on the dynamic offset.
[0018] In some examples of the method, UEs, and non-transitory computer-readable medium described herein, determining the dynamic offset using the iteration loop may include operations, features, means, or instructions for decreasing the dynamic offset based on a successful decoding of the physical downlink shared channel message and increasing the dynamic offset based on an unsuccessful decoding of the physical downlink shared channel message.

[0021] In some examples of the method, UEs, and non-transitory computer-readable medium described herein, the maximum configured transmit power for PUSCH transmissions that include analog CSI may be different from a second maximum configured transmit power for associated with one or more other types of uplink transmissions.
[0022] In some examples of the method, UEs, and non-transitory computer-readable medium described herein, transmitting the PUSCH transmission may include operations, features, means, or instructions for transmitting, in a same subframe as the first set of analog CSI, a power headroom report (PHR) for the first set of analog CSI, where the PHR may be based on the PUSCH transmission.
[0023] In some examples of the method, UEs, and non-transitory computer-readable medium described herein, the PHR indicates whether the transmit power may be less than or equal to a maximum configured transmit power for PUSCH transmissions that include analog CSI.
[0024] Some examples of the method, UEs, and non-transitory computer-readable medium described herein may further include operations, features, means, or instructions for determining, based on the PUSCH transmission including the first set of analog CSI and further based on a carrier aggregation or dual connectivity configuration for the UE, a power reduction priority for the PUSCH transmission based on an assumption that each symbol of a set of symbols associated with the PUSCH transmission may have a same transmit power.
[0025] In some examples of the method, UEs, and non-transitory computer-readable medium described herein, the first set of analog CSI includes a set of multiple channel coefficients corresponding to a set of multiple channel taps and the set of multiple channel coefficients included in the first set of analog CSI may be not quantized prior to being transmitted in the PUSCH transmission.

[0036] In some wireless communications systems, a user equipment (UE) may receive one or more reference signals from a network entity (e.g., base station) and the UE may provide a channel state information (CSI) report to the network entity. The CSI report may indicate one or more parameters indicative of channel conditions, which may be based on measurements performed by the UE on the one or more reference signals. CSI for the CSI report may be quantized or transformed before reporting to the network entity. Quantizing a CSI component (e.g., a channel coefficient, a spatial domain basis, a frequency domain basis, or a time domain basis that is included in the CSI that is to be indicated by the CSI report) may refer to generating a digital indicator (e.g., a set of one or more bits) that represents the CSI component. However, defining quantization levels for quantizing the CSI may involve tradeoffs between overhead and resolution. For example, if 12-bit digital indicators are generated for each channel coefficient or other CSI component that is to be indicated via a CSI report, this may provide high resolution but relatively high overhead, whereas if 7-bit digital indicators are generated for each channel coefficient or other CSI component that is to be indicated via a CSI report, this may provide lower overhead by relatively low resolution.
[0037] As discussed herein, the UE may transmit a CSI report where at least a portion of the CSI report is not quantized. CSI that is not quantized may be referred to as analog CSI. Along with not quantizing the analog CSI (e.g., not generating digital representations thereof, at least not according to a same resolution or quantization level) , the UE may not apply channel coding to the analog CSI-rather, the UE may identify coefficients (e.g., time domain coefficients) included in the analog CSI and map the coefficients to resource elements via which the analog CSI is transmitted (e.g., without any intervening channel coding, while treating the analog coefficients as though they were modulated symbols, or both) , possibly with the use of a spreading matrix to align the quantity of analog coefficients to be indicated with the quantity of resource elements to be used to transmit the analog CSI. As such, it could be said that analog CSI refers to CSI that that is not quantized prior to being mapped to resource elements for transmission and / or is not subjected to channel coding prior to being mapped to resource elements for transmission. In contrast, digital CSI may be quantized and / or subjected to channel coding (e.g., after quantization) prior to being mapped to resource elements for transmission.
[0038] As described above, analog CSI (e.g., one or more signals carrying analog CSI) may be unquantized and uncoded. Thus, in some wireless communications systems, a UE transmitting such an analog CSI may experience impairments such as noise, fading, and interference if a power level of the analog CSI is too low. This may degrade reliability. If the power level is too high, the signal may cause interference to other signals, and may result in inefficient energy use. Thus, solutions for an efficient power control strategy that improves reliability of an analog CSI feedback signal are desirable.
[0039] Techniques described herein may provide for UE to receive a configuration with multiple parameter sets that are applicable for respective uplink transmissions. That is, the UE may receive a first configuration that includes a first power control parameter set and a second power control parameter set. The first power control parameter set may be for physical uplink shared channel (PUSCH) transmissions that are devoid of analog CSI. The second power control parameter set may be different than the first power control parameter set and may be for PUSCH transmissions that include analog CSI. Then, the UE may transmit, using a transmit power that is based on the second power control parameter set, a PUSCH transmission that includes a first set of analog CSI. Similarly, the UE may transmit, using a second transmit power that is based on the first power control parameter set, a second PUSCH transmission that is devoid of analog CSI. The UE may determine which power control parameter set to use for transmission based on information in a PUSCH transmission, downlink control information (DCI) from a network entity, a transmit power spectral density (PSD) for analog CSI, a dynamic offset for analog CSI, or any combination thereof.
[0040] Aspects of the disclosure are initially described in the context of wireless communications systems. Aspects of the disclosure are then described in the context of flow diagrams and a process flow. Aspects of the disclosure are further illustrated by and described with reference to apparatus diagrams, system diagrams, and flowcharts that relate to power control for analog CSI over an uplink shared channel.
[0041] FIG. 1 shows an example of a wireless communications system 100 that supports power control for analog CSI over an uplink shared channel in accordance with one or more aspects of the present disclosure. The wireless communications system 100 may include one or more devices, such as one or more network devices (e.g., network entities 105) , one or more UEs 115, and a core network 130. In some examples, the wireless communications system 100 may be a Long Term Evolution (LTE) network, an LTE-Advanced (LTE-A) network, an LTE-A Pro network, a New Radio (NR) network, or a network operating in accordance with other systems and radio technologies, including future systems and radio technologies not explicitly mentioned herein.
[0042] The network entities 105 may be dispersed throughout a geographic area to form the wireless communications system 100 and may include devices in different forms or having different capabilities. In various examples, a network entity 105 may be referred to as a network element, a mobility element, a radio access network (RAN) node, or network equipment, among other nomenclature. In some examples, network entities 105 and UEs 115 may wirelessly communicate via communication link (s) 125 (e.g., a radio frequency (RF) access link) . For example, a network entity 105 may support a coverage area 110 (e.g., a geographic coverage area) over which the UEs 115 and the network entity 105 may establish the communication link (s) 125. The coverage area 110 may be an example of a geographic area over which a network entity 105 and a UE 115 may support the communication of signals according to one or more radio access technologies (RATs) .
[0043] The UEs 115 may be dispersed throughout a coverage area 110 of the wireless communications system 100, and each UE 115 may be stationary, or mobile, or both at different times. The UEs 115 may be devices in different forms or having different capabilities. Some example UEs 115 are illustrated in FIG. 1. The UEs 115 described herein may be capable of supporting communications with various types of devices in the wireless communications system 100 (e.g., other wireless communication devices, including UEs 115 or network entities 105) , as shown in FIG. 1.
[0044] As described herein, a node of the wireless communications system 100, which may be referred to as a network node, or a wireless node, may be a network entity 105 (e.g., any network entity described herein) , a UE 115 (e.g., any UE described herein) , a network controller, an apparatus, a device, a computing system, one or more components, or another suitable processing entity configured to perform any of the techniques described herein. For example, a node may be a UE 115. As another example, a node may be a network entity 105. As another example, a first node may be configured to communicate with a second node or a third node. In one aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a UE 115. In another aspect of this example, the first node may be a UE 115, the second node may be a network entity 105, and the third node may be a network entity 105. In yet other aspects of this example, the first, second, and third nodes may be different relative to these examples. Similarly, reference to a UE 115, network entity 105, apparatus, device, computing system, or the like may include disclosure of the UE 115, network entity 105, apparatus, device, computing system, or the like being a node. For example, disclosure that a UE 115 is configured to receive information from a network entity 105 also discloses that a first node is configured to receive information from a second node.
[0045] In some examples, network entities 105 may communicate with a core network 130, or with one another, or both. For example, network entities 105 may communicate with the core network 130 via backhaul communication link (s) 120 (e.g., in accordance with an S1, N2, N3, or other interface protocol) . In some examples, network entities 105 may communicate with one another via backhaul communication link (s) 120 (e.g., in accordance with an X2, Xn, or other interface protocol) either directly (e.g., directly between network entities 105) or indirectly (e.g., via the core network 130) . In some examples, network entities 105 may communicate with one another via a midhaul communication link 162 (e.g., in accordance with a midhaul interface protocol) or a fronthaul communication link 168 (e.g., in accordance with a fronthaul interface protocol) , or any combination thereof. The backhaul communication link (s) 120, midhaul communication links 162, or fronthaul communication links 168 may be or include one or more wired links (e.g., an electrical link, an optical fiber link) or one or more wireless links (e.g., a radio link, a wireless optical link) , among other examples or various combinations thereof. A UE 115 may communicate with the core network 130 via a communication link 155.
[0046] One or more of the network entities 105 or network equipment described herein may include or may be referred to as a base station 140 (e.g., a base transceiver station, a radio base station, an NR base station, an access point, a radio transceiver, a NodeB, an eNodeB (eNB) , a next-generation NodeB or giga-NodeB (either of which may be referred to as a gNB) , a 5G NB, a next-generation eNB (ng-eNB) , a Home NodeB, a Home eNodeB, or other suitable terminology) . In some examples, a network entity 105 (e.g., a base station 140) may be implemented in an aggregated (e.g., monolithic, standalone) base station architecture, which may be configured to utilize a protocol stack that is physically or logically integrated within one network entity (e.g., a network entity 105 or a single RAN node, such as a base station 140) .
[0047] In some examples, a network entity 105 may be implemented in a disaggregated architecture (e.g., a disaggregated base station architecture, a disaggregated RAN architecture) , which may be configured to utilize a protocol stack that is physically or logically distributed among multiple network entities (e.g., network entities 105) , such as an integrated access and backhaul (IAB) network, an open RAN (O-RAN) (e.g., a network configuration sponsored by the O-RAN Alliance) , or a virtualized RAN (vRAN) (e.g., a cloud RAN (C-RAN) ) . For example, a network entity 105 may include one or more of a central unit (CU) , such as a CU 160, a distributed unit (DU) , such as a DU 165, a radio unit (RU) , such as an RU 170, a RAN Intelligent Controller (RIC) , such as an RIC 175 (e.g., a Near-Real Time RIC (Near-RT RIC) , a Non-Real Time RIC (Non-RT RIC) ) , a Service Management and Orchestration (SMO) system, such as an SMO system 180, or any combination thereof. An RU 170 may also be referred to as a radio head, a smart radio head, a remote radio head (RRH) , a remote radio unit (RRU) , or a transmission reception point (TRP) . One or more components of the network entities 105 in a disaggregated RAN architecture may be co-located, or one or more components of the network entities 105 may be located in distributed locations (e.g., separate physical locations) . In some examples, one or more of the network entities 105 of a disaggregated RAN architecture may be implemented as virtual units (e.g., a virtual CU (VCU) , a virtual DU (VDU) , a virtual RU (VRU) ) .
[0048] The split of functionality between a CU 160, a DU 165, and an RU 170 is flexible and may support different functionalities depending on which functions (e.g., network layer functions, protocol layer functions, baseband functions, RF functions, or any combinations thereof) are performed at a CU 160, a DU 165, or an RU 170. For example, a functional split of a protocol stack may be employed between a CU 160 and a DU 165 such that the CU 160 may support one or more layers of the protocol stack and the DU 165 may support one or more different layers of the protocol stack. In some examples, the CU 160 may host upper protocol layer (e.g., layer 3 (L3) , layer 2 (L2) ) functionality and signaling (e.g., Radio Resource Control (RRC) , service data adaptation protocol (SDAP) , Packet Data Convergence Protocol (PDCP) ) . The CU 160 (e.g., one or more CUs) may be connected to a DU 165 (e.g., one or more DUs) or an RU 170 (e.g., one or more RUs) , or some combination thereof, and the DUs 165, RUs 170, or both may host lower protocol layers, such as layer 1 (L1) (e.g., physical (PHY) layer) or L2 (e.g., radio link control (RLC) layer, medium access control (MAC) layer) functionality and signaling, and may each be at least partially controlled by the CU 160. Additionally, or alternatively, a functional split of the protocol stack may be employed between a DU 165 and an RU 170 such that the DU 165 may support one or more layers of the protocol stack and the RU 170 may support one or more different layers of the protocol stack. The DU 165 may support one or multiple different cells (e.g., via one or multiple different RUs, such as an RU 170) . In some cases, a functional split between a CU 160 and a DU 165 or between a DU 165 and an RU 170 may be within a protocol layer (e.g., some functions for a protocol layer may be performed by one of a CU 160, a DU 165, or an RU 170, while other functions of the protocol layer are performed by a different one of the CU 160, the DU 165, or the RU 170) . A CU 160 may be functionally split further into CU control plane (CU-CP) and CU user plane (CU-UP) functions. A CU 160 may be connected to a DU 165 via a midhaul communication link 162 (e.g., F1, F1-c, F1-u) , and a DU 165 may be connected to an RU 170 via a fronthaul communication link 168 (e.g., open fronthaul (FH) interface) . In some examples, a midhaul communication link 162 or a fronthaul communication link 168 may be implemented in accordance with an interface (e.g., a channel) between layers of a protocol stack supported by respective network entities (e.g., one or more of the network entities 105) that are in communication via such communication links.
[0049] In some wireless communications systems (e.g., the wireless communications system 100) , infrastructure and spectral resources for radio access may support wireless backhaul link capabilities to supplement wired backhaul connections, providing an IAB network architecture (e.g., to a core network 130) . In some cases, in an IAB network, one or more of the network entities 105 (e.g., network entities 105 or IAB node (s) 104) may be partially controlled by each other. The IAB node (s) 104 may be referred to as a donor entity or an IAB donor. A DU 165 or an RU 170 may be partially controlled by a CU 160 associated with a network entity 105 or base station 140 (such as a donor network entity or a donor base station) . The one or more donor entities (e.g., IAB donors) may be in communication with one or more additional devices (e.g., IAB node (s) 104) via supported access and backhaul links (e.g., backhaul communication link (s) 120) . IAB node (s) 104 may include an IAB mobile termination (IAB-MT) controlled (e.g., scheduled) by one or more DUs (e.g., DUs 165) of a coupled IAB donor. An IAB-MT may be equipped with an independent set of antennas for relay of communications with UEs 115 or may share the same antennas (e.g., of an RU 170) of IAB node (s) 104 used for access via the DU 165 of the IAB node (s) 104 (e.g., referred to as virtual IAB-MT (vIAB-MT) ) . In some examples, the IAB node (s) 104 may include one or more DUs (e.g., DUs 165) that support communication links with additional entities (e.g., IAB node (s) 104, UEs 115) within the relay chain or configuration of the access network (e.g., downstream) . In such cases, one or more components of the disaggregated RAN architecture (e.g., the IAB node (s) 104 or components of the IAB node (s) 104) may be configured to operate according to the techniques described herein.
[0050] In the case of the techniques described herein applied in the context of a disaggregated RAN architecture, one or more components of the disaggregated RAN architecture may be configured to support test as described herein. For example, some operations described as being performed by a UE 115 or a network entity 105 (e.g., a base station 140) may additionally, or alternatively, be performed by one or more components of the disaggregated RAN architecture (e.g., components such as an IAB node, a DU 165, a CU 160, an RU 170, an RIC 175, an SMO system 180) .
[0051] A UE 115 may include or may be referred to as a mobile device, a wireless device, a remote device, a handheld device, or a subscriber device, or some other suitable terminology, where the “device” may also be referred to as a unit, a station, a terminal, or a client, among other examples. A UE 115 may also include or may be referred to as a personal electronic device such as a cellular phone, a personal digital assistant (PDA) , a tablet computer, a laptop computer, or a personal computer. In some examples, a UE 115 may include or be referred to as a wireless local loop (WLL) station, an Internet of Things (IoT) device, an Internet of Everything (IoE) device, or a machine type communications (MTC) device, among other examples, which may be implemented in various objects such as appliances, vehicles, or meters, among other examples.
[0052] The UEs 115 described herein may be able to communicate with various types of devices, such as UEs 115 that may sometimes operate as relays, as well as the network entities 105 and the network equipment including macro eNBs or gNBs, small cell eNBs or gNBs, or relay base stations, among other examples, as shown in FIG. 1.
[0053] The UEs 115 and the network entities 105 may wirelessly communicate with one another via the communication link (s) 125 (e.g., one or more access links) using resources associated with one or more carriers. The term “carrier” may refer to a set of RF spectrum resources having a defined PHY layer structure for supporting the communication link (s) 125. For example, a carrier used for the communication link (s) 125 may include a portion of an RF spectrum band (e.g., a bandwidth part (BWP) ) that is operated according to one or more PHY layer channels for a given RAT (e.g., LTE, LTE-A, LTE-A Pro, NR) . Each PHY layer channel may carry acquisition signaling (e.g., synchronization signals, system information) , control signaling that coordinates operation for the carrier, user data, or other signaling. The wireless communications system 100 may support communication with a UE 115 using carrier aggregation or multi-carrier operation. A UE 115 may be configured with multiple downlink component carriers and one or more uplink component carriers according to a carrier aggregation configuration. Carrier aggregation may be used with both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers. Communication between a network entity 105 and other devices may refer to communication between the devices and any portion (e.g., entity, sub-entity) of a network entity 105. For example, the terms “transmitting, ” “receiving, ” or “communicating, ” when referring to a network entity 105, may refer to any portion of a network entity 105 (e.g., a base station 140, a CU 160, a DU 165, a RU 170) of a RAN communicating with another device (e.g., directly or via one or more other network entities, such as one or more of the network entities 105) .
[0054] Signal waveforms transmitted via a carrier may be made up of multiple subcarriers (e.g., using multi-carrier modulation (MCM) techniques such as orthogonal frequency division multiplexing (OFDM) or discrete Fourier transform spread OFDM (DFT-S-OFDM) ) . In a system employing MCM techniques, a resource element may refer to resources of one symbol period (e.g., a duration of one modulation symbol) and one subcarrier, in which case the symbol period and subcarrier spacing may be inversely related. The quantity of bits carried by each resource element may depend on the modulation scheme (e.g., the order of the modulation scheme, the coding rate of the modulation scheme, or both) , such that a relatively higher quantity of resource elements (e.g., in a transmission duration) and a relatively higher order of a modulation scheme may correspond to a relatively higher rate of communication. A wireless communications resource may refer to a combination of an RF spectrum resource, a time resource, and a spatial resource (e.g., a spatial layer, a beam) , and the use of multiple spatial resources may increase the data rate or data integrity for communications with a UE 115.
[0055] The time intervals for the network entities 105 or the UEs 115 may be expressed in multiples of a basic time unit which may, for example, refer to a sampling period of Ts=1 / (Δfmax·Nf) seconds, for which Δfmax may represent a supported subcarrier spacing, and Nf may represent a supported discrete Fourier transform (DFT) size. Time intervals of a communications resource may be organized according to radio frames each having a specified duration (e.g., 10 milliseconds (ms) ) . Each radio frame may be identified by a system frame number (SFN) (e.g., ranging from 0 to 1023) .
[0056] Each frame may include multiple consecutively-numbered subframes or slots, and each subframe or slot may have the same duration. In some examples, a frame may be divided (e.g., in the time domain) into subframes, and each subframe may be further divided into a quantity of slots. Alternatively, each frame may include a variable quantity of slots, and the quantity of slots may depend on subcarrier spacing. Each slot may include a quantity of symbol periods (e.g., depending on the length of the cyclic prefix prepended to each symbol period) . In some wireless communications systems, such as the wireless communications system 100, a slot may further be divided into multiple mini-slots associated with one or more symbols. Excluding the cyclic prefix, each symbol period may be associated with one or more (e.g., Nf) sampling periods. The duration of a symbol period may depend on the subcarrier spacing or frequency band of operation.
[0057] A subframe, a slot, a mini-slot, or a symbol may be the smallest scheduling unit (e.g., in the time domain) of the wireless communications system 100 and may be referred to as a transmission time interval (TTI) . In some examples, the TTI duration (e.g., a quantity of symbol periods in a TTI) may be variable. Additionally, or alternatively, the smallest scheduling unit of the wireless communications system 100 may be dynamically selected (e.g., in bursts of shortened TTIs (sTTIs) ) .
[0058] Physical channels may be multiplexed for communication using a carrier according to various techniques. A physical control channel and a physical data channel may be multiplexed for signaling via a downlink carrier, for example, using one or more of time division multiplexing (TDM) techniques, frequency division multiplexing (FDM) techniques, or hybrid TDM-FDM techniques. A control region (e.g., a control resource set (CORESET) ) for a physical control channel may be defined by a set of symbol periods and may extend across the system bandwidth or a subset of the system bandwidth of the carrier. One or more control regions (e.g., CORESETs) may be configured for a set of the UEs 115. For example, one or more of the UEs 115 may monitor or search control regions for control information according to one or more search space sets, and each search space set may include one or multiple control channel candidates in one or more aggregation levels arranged in a cascaded manner. An aggregation level for a control channel candidate may refer to an amount of control channel resources (e.g., control channel elements (CCEs) ) associated with encoded information for a control information format having a given payload size. Search space sets may include common search space sets configured for sending control information to UEs 115 (e.g., one or more UEs) or may include UE-specific search space sets for sending control information to a UE 115 (e.g., a specific UE) .
[0059] In some examples, a network entity 105 (e.g., a base station 140, an RU 170) may be movable and therefore provide communication coverage for a moving coverage area, such as the coverage area 110. In some examples, coverage areas 110 (e.g., different coverage areas) associated with different technologies may overlap, but the coverage areas 110 (e.g., different coverage areas) may be supported by the same network entity (e.g., a network entity 105) . In some other examples, overlapping coverage areas, such as a coverage area 110, associated with different technologies may be supported by different network entities (e.g., the network entities 105) . The wireless communications system 100 may include, for example, a heterogeneous network in which different types of the network entities 105 support communications for coverage areas 110 (e.g., different coverage areas) using the same or different RATs.
[0060] The wireless communications system 100 may be configured to support ultra-reliable communications or low-latency communications, or various combinations thereof. For example, the wireless communications system 100 may be configured to support ultra-reliable low-latency communications (URLLC) . The UEs 115 may be designed to support ultra-reliable, low-latency, or critical functions. Ultra-reliable communications may include private communication or group communication and may be supported by one or more services such as push-to-talk, video, or data. Support for ultra-reliable, low-latency functions may include prioritization of services, and such services may be used for public safety or general commercial applications. The terms ultra-reliable, low-latency, and ultra-reliable low-latency may be used interchangeably herein.
[0061] In some examples, a UE 115 may be configured to support communicating directly with other UEs (e.g., one or more of the UEs 115) via a device-to-device (D2D) communication link, such as a D2D communication link 135 (e.g., in accordance with a peer-to-peer (P2P) , D2D, or sidelink protocol) . In some examples, one or more UEs 115 of a group that are performing D2D communications may be within the coverage area 110 of a network entity 105 (e.g., a base station 140, an RU 170) , which may support aspects of such D2D communications being configured by (e.g., scheduled by) the network entity 105. In some examples, one or more UEs 115 of such a group may be outside the coverage area 110 of a network entity 105 or may be otherwise unable to or not configured to receive transmissions from a network entity 105. In some examples, groups of the UEs 115 communicating via D2D communications may support a one-to-many (1: M) system in which each UE 115 transmits to one or more of the UEs 115 in the group. In some examples, a network entity 105 may facilitate the scheduling of resources for D2D communications. In some other examples, D2D communications may be carried out between the UEs 115 without an involvement of a network entity 105.
[0062] The core network 130 may provide user authentication, access authorization, tracking, Internet Protocol (IP) connectivity, and other access, routing, or mobility functions. The core network 130 may be an evolved packet core (EPC) or 5G core (5GC) , which may include at least one control plane entity that manages access and mobility (e.g., a mobility management entity (MME) , an access and mobility management function (AMF) ) and at least one user plane entity that routes packets or interconnects to external networks (e.g., a serving gateway (S-GW) , a Packet Data Network (PDN) gateway (P-GW) , or a user plane function (UPF) ) . The control plane entity may manage non-access stratum (NAS) functions such as mobility, authentication, and bearer management for the UEs 115 served by the network entities 105 (e.g., base stations 140) associated with the core network 130. User IP packets may be transferred through the user plane entity, which may provide IP address allocation as well as other functions. The user plane entity may be connected to IP services 150 for one or more network operators. The IP services 150 may include access to the Internet, Intranet (s) , an IP Multimedia Subsystem (IMS) , or a Packet-Switched Streaming Service.
[0063] The wireless communications system 100 may operate using one or more frequency bands, which may be in the range of 300 megahertz (MHz) to 300 gigahertz (GHz) . Generally, the region from 300 MHz to 3 GHz is known as the ultra-high frequency (UHF) region or decimeter band because the wavelengths range from approximately one decimeter to one meter in length. UHF waves may be blocked or redirected by buildings and environmental features, which may be referred to as clusters, but the waves may penetrate structures sufficiently for a macro cell to provide service to the UEs 115 located indoors. Communications using UHF waves may be associated with smaller antennas and shorter ranges (e.g., less than one hundred kilometers) compared to communications using the smaller frequencies and longer waves of the high frequency (HF) or very high frequency (VHF) portion of the spectrum below 300 MHz.
[0064] The wireless communications system 100 may utilize both licensed and unlicensed RF spectrum bands. For example, the wireless communications system 100 may employ License Assisted Access (LAA) , LTE-Unlicensed (LTE-U) RAT, or NR technology using an unlicensed band such as the 5 GHz industrial, scientific, and medical (ISM) band. While operating using unlicensed RF spectrum bands, devices such as the network entities 105 and the UEs 115 may employ carrier sensing for collision detection and avoidance. In some examples, operations using unlicensed bands may be based on a carrier aggregation configuration in conjunction with component carriers operating using a licensed band (e.g., LAA) . Operations using unlicensed spectrum may include downlink transmissions, uplink transmissions, P2P transmissions, or D2D transmissions, among other examples.
[0065] A network entity 105 (e.g., a base station 140, an RU 170) or a UE 115 may be equipped with multiple antennas, which may be used to employ techniques such as transmit diversity, receive diversity, multiple-input multiple-output (MIMO) communications, or beamforming. The antennas of a network entity 105 or a UE 115 may be located within one or more antenna arrays or antenna panels, which may support MIMO operations or transmit or receive beamforming. For example, one or more base station antennas or antenna arrays may be co-located at an antenna assembly, such as an antenna tower. In some examples, antennas or antenna arrays associated with a network entity 105 may be located at diverse geographic locations. A network entity 105 may include an antenna array with a set of rows and columns of antenna ports that the network entity 105 may use to support beamforming of communications with a UE 115. Likewise, a UE 115 may include one or more antenna arrays that may support various MIMO or beamforming operations. Additionally, or alternatively, an antenna panel may support RF beamforming for a signal transmitted via an antenna port.
[0066] The network entities 105 or the UEs 115 may use MIMO communications to exploit multipath signal propagation and increase spectral efficiency by transmitting or receiving multiple signals via different spatial layers. Such techniques may be referred to as spatial multiplexing. The multiple signals may, for example, be transmitted by the transmitting device via different antennas or different combinations of antennas. Likewise, the multiple signals may be received by the receiving device via different antennas or different combinations of antennas. Each of the multiple signals may be referred to as a separate spatial stream and may carry information associated with the same data stream (e.g., the same codeword) or different data streams (e.g., different codewords) . Different spatial layers may be associated with different antenna ports used for channel measurement and reporting. MIMO techniques include single-user MIMO (SU-MIMO) , for which multiple spatial layers are transmitted to the same receiving device, and multiple-user MIMO (MU-MIMO) , for which multiple spatial layers are transmitted to multiple devices.
[0067] Beamforming, which may also be referred to as spatial filtering, directional transmission, or directional reception, is a signal processing technique that may be used at a transmitting device or a receiving device (e.g., a network entity 105, a UE 115) to shape or steer an antenna beam (e.g., a transmit beam, a receive beam) along a spatial path between the transmitting device and the receiving device. Beamforming may be achieved by combining the signals communicated via antenna elements of an antenna array such that some signals propagating along particular orientations with respect to an antenna array experience constructive interference while others experience destructive interference. The adjustment of signals communicated via the antenna elements may include a transmitting device or a receiving device applying amplitude offsets, phase offsets, or both to signals carried via the antenna elements associated with the device. The adjustments associated with each of the antenna elements may be defined by a beamforming weight set associated with a particular orientation (e.g., with respect to the antenna array of the transmitting device or receiving device, or with respect to some other orientation) .
[0068] In some wireless communications systems, analog feedback may outperform digital reporting for digital feedback. In some cases, a device may transmit CSI in analog form for FDD communications. A digital scheme may be limited by a quantity of bits (e.g., for quantization or resolution) . For achieving “high resolution CSI” at a relatively high signal-to-noise ratio (SNR) , a UE may report non-zero coefficients and may also increase a quantization level (e.g., 7 bits per coefficient to 12–14 bits) , which may result in a significant increase in feedback overhead (e.g., several hundreds of bits to several thousands of bits) . In analog CSI feedback, a UE may treat time domain channel coefficients across transmission and reception antenna pair and the delay taps (e.g., non-zero per-tap channel coefficient) as modulated symbol. Further the UE may directly map the time domain channel coefficients (e.g., complex number) to the uplink channel without quantization or channel coding. The UE may adapt a quantity of active taps or channel coefficients for reporting according to an associated SNR, which may reduce the feedback overhead.
[0069] For analog feedback, a UE may report (e.g., digitally) a location of active channel tap with non-zero power larger than a threshold. In analog feedback, a UE may follow a joint source-channel coding approach and may directly map the downlink CSI to the uplink channel input in an unquantized and uncoded manner. In digital feedback, the UE may first compress and quantize the CSI to as few bits as possible. The UE may reliably feed the bits back to a transmitter using a low-rate channel code.
[0070] A UE may calculate a UE transmit power (e.g., a transmit power of any uplink channel transmission such as sounding reference signal (SRS) , PUSCH, or physical uplink control channel (PUCCH) ) according to a formula such as formula (1) .
[0071] Transmit Power=Rx+P+M+R+C (1)
[0072] where the variables of formula (1) may represent respective values as follows.
[0073] Rx is a target reference Rx power P0 that includes a common power level for all UEs in the cell and a UE specific offset. Different reference levels can be configured for different channels considering different block error rate (BLER) targets.
[0074] P is a pathloss component that is used to scale an effect of pathloss. A fractional pathloss compensation factor α may have a value from 0 to 1. α = 1 may indicate full pathloss compensation and α < 1 may indicate partial pathloss compensation. A UE may use a full pathloss component for PUCCH and may apply a partial pathloss compensation to other uplink signals, such as for PUSCH or SRS.
[0075] M is a modulation and coding scheme (MCS) factor Δ_TF which allows the transmitted power per resource block or transmit power spectral density (PSD) to be adapted according to a transmitted information rate. This may enable a network entity to adjust a PSD relatively quickly based on an MCS, (e.g., higher MCS values may correspond to larger PSD values) . The UE may apply an MCS based power control to a PUCCH transmission (e.g., taking into account a quantity of information to be transmitted on PUCCH) .
[0076] R is a resource block factor, which a UE may use to adjust the transmit power according to a quantity of resource blocks allocated (e.g., the R value may be linearly proportional to a quantity of resource blocks) .
[0077] C is a close-loop adjustment value that is based on UE specific transmit power control (TPC) . The UE may operate the close-loop adjustment value in two modes. A first mode may be based on accumulative TPC commands (e.g., available for PUSCH, PUCCH and SRS) . A second mode may be based on absolute TPC commands (e.g., available for PUSCH and SRS) .
[0078] In some wireless communications systems, for analog feedback, a reported CSI is unquantized and uncoded, making it susceptible to various impairments such as noise, fading and interference which may degrade reliability. If a power level of the analog CSI signal is too low, the signal may be drowned out by noise and interference, which may increase the feedback error. As a result, a network entity may be unable to re-construct the CSI accurately. On the other hand, if the power level is too high, it may cause interference to other users and may waste energy. Thus, solutions for an efficient power control strategy that can maintain the reliability of analog CSI while minimizing energy consumption and interference are desirable (e.g., allocating power efficiently based on the channel conditions to ensure reliable feedback and maximize performance) .
[0079] As described herein, a wireless communications system 100 may support a UE 115 to receive a configuration with multiple parameter sets that are applicable for respective uplink transmissions. That is, the UE 115 may receive a first configuration that includes a first power control parameter set and a second power control parameter set. The first power control parameter set may be for physical uplink shared channel (PUSCH) transmissions that are devoid of analog CSI. The second power control parameter set may be different than the first power control parameter set and may be for PUSCH transmissions that include analog CSI. Then, the UE 115 may transmit, using a transmit power that is based on the second power control parameter set, a PUSCH transmission that includes a first set of analog CSI to a network entity 105. Similarly, the UE 115 may transmit, using a second transmit power that is based on the first power control parameter set, a second PUSCH transmission that is devoid of analog CSI. The UE 115 may determine which power control parameter set to use for transmission based on information in a PUSCH transmission, DCI from the network entity 105, a transmit power spectral density for analog CSI, a dynamic offset for analog CSI, or any combination thereof.
[0080] FIG. 2 shows an example of a wireless communications system 200 that supports power control for analog CSI over an uplink shared channel in accordance with one or more aspects of the present disclosure. In some cases, the wireless communications system 200 may implement or be implemented by aspects of the wireless communications system 100. For example, the wireless communications system 200 may include one or more UEs 115 (e.g., a UE 115-a) and one or more network entities 105 (e.g., a network entity 105-a) , which may be examples of the corresponding devices as described herein. The UE 115-a may receive one or more messages from the network entity 105-a via a downlink communication link 205 (e.g., via a downlink channel) . Similarly, the UE 115-a may transmit one or more messages to the network entity 105-a via an uplink communication link 210 (e.g., via an uplink channel such as a PUSCH) .
[0081] In some implementations, the UE 115-a may receive, from the network entity 105-a and via the downlink communication link 205, a configuration 215. The configuration 215 may include one or more parameter sets (e.g., a first parameter set and a second parameter set) . In some cases, the UE 115-a may receive, from the network entity 105-a and via the downlink communication link 205, a set of one or more downlink reference signals 220. Then, the UE 115-a may transmit, to the network entity 105-a and via the uplink communication link 210, a PUSCH transmission 225. In some cases, the UE 115-a may transmit the PUSCH transmission 225 using a transmit power according to a parameter set within the configuration 215. In some examples, the UE 115-a may adjust the transmit power based on the set of one or more downlink reference signals 220. For example, the UE 115-a may measure a downlink reference signal 220 of the set (or multiple downlink reference signals 220 of the set) and may use the resulting measurements to calculate the transmit power for the PUSCH transmission 225. The UE 115-a may also receive (e.g., as part of the configuration 215) an indication of one or more values (e.g., a measurement, an offset, a threshold, or the like) which the UE 115-a may use to calculate the transmit power. Although the techniques described herein refer to PUSCH transmissions, these techniques may also be similarly applied to other types of uplink transmission in some examples.
[0082] In some implementations, the configuration 215 may include a first parameter set, which may be for non-analog CSI feedback (e.g., over PUSCH) . The configuration 215 may also include a second (e.g., separate, or different) parameter set for analog CSI feedback (e.g., over PUSCH) . As described herein, the first parameter set and the second parameter set may be referred to as a first power control parameter set and a second power control parameter set, respectively.
[0083] The UE 115-a may select either the first parameter set or the second parameter set for calculating the transmit power based on one or more factors associated with the PUSCH transmission 225, the set of one or more downlink reference signals 220, or both. For example, the UE 115-a may select the second parameter set if the PUSCH transmission 225 includes analog CSI and is devoid of (e.g., does not include) uplink shared channel data. In some cases, the PUSCH transmission 225 may include both analog CSI and uplink shared channel data or may include both hybrid analog CSI and digital CSI. In such cases, the UE 115-a may receive, from the network entity 105-a, a message (e.g., via RRC or DCI) that indicates whether the UE 115-a is to use the first parameter set or the second parameter set.
[0084] The second parameter set may include at least one common power offset (e.g., P0_NOMINAL) and a set of UE specific offset values (e.g., one or more P0_UE values) . The values may be different from those in the first parameter set. The second parameter set may include an alpha value, which may be fixed at a value of one (e.g., indicating full pathloss compensation for analog CSI) . In some cases (e.g., as a first alternative) , the network entity 105-a may dynamically indicate one UE specific offset value (e.g., a particular P0_UE) from the set via a downlink message (e.g., an SRS resource indicator (SRI) field of a DCI or any other indicator for analog CSI feedback over PUSCH) .
[0085] In some examples (e.g., as a second alternative) , the UE may select a UE specific offset value from the set based on one or more values associated with downlink communication or feedback (e.g., a downlink SNR value, an uplink SNR value, feedback channel coefficients, or both) . In some implementations, the network entity 105-a may provide one or more criteria to guide the selection at the UE 115-a. For example, the UE may receive, from the network entity 105-a, signaling that indicates a target receive power. Additionally, or alternatively, the UE 115-a may identify a target receive power based on a configuration of the UE 115-a. In some cases, the signaling may indicate that the target receive power is to be used for a set of channel taps (e.g., all channel taps) or for a subset of channel taps. Additionally, or alternatively, the signaling may define the subset of channel taps (e.g., according to a rule) . Accordingly, the UE 115-a may identify the subset of channel taps and may apply the target receive power to the subset based on one or more conditions indicated in the signaling. In some cases, the selection at the UE (e.g., the second alternative) may result in a reported channel coefficient (e.g., associated with a weak tap) meeting a target receive power (e.g., in cases where the UE 115-a reports both strong and weak taps) . This may increase feedback reliability and may reduce feedback error.
[0086] In some cases, the UE 115-a may calculate a dynamic power offset using one or more analog coefficients (e.g., associated with the PUSCH transmission 225 including analog CSI) . For example, the UE 115-a may calculate the dynamic power offset according to one or more methods as described with reference to FIGs. 4A and 4B. Then, the UE 115-a may apply the dynamic power offset to the transmit power (e.g., increasing or decreasing the transmit power) .
[0087] In some implementations, the UE 115-a may determine the dynamic power offset (e.g., for analog CSI) based on an iteration loop. The iteration loop may be based on a BLER associated with decoding a set of one or more physical downlink shared channel (PDSCH) transmissions which is based on analog CSI (e.g., a PUSCH transmission that includes analog CSI) . For example, the UE 115-a may increase the dynamic power offset by a first value (e.g., a first delta value) for a detected negative acknowledgment (NACK) (e.g., based on an unsuccessful decoding of a PDSCH message at the UE 115-a) . Similarly, the UE 115-a may decrease the dynamic power offset by a second value (e.g., a second delta value, which may be equal to the first delta value) for a detected acknowledgment (ACK) (e.g., based on a successful decoding of a PDSCH message at the UE 115-a) . In some cases, the first value and the second value (e.g., the step size “delta” ) may be configurable (e.g., by the UE 115-a or the network entity 105-a) .
[0088] In some implementations, the UE 115-a may support close-loop power control adjustment for analog CSI feedback based on (e.g., by leveraging) a TPC indicator in a DCI message received from the network entity 105-a. For example, the UE 115-a may use a power control loop to track changes in channel conditions. The UE 115-a may apply the power control loop for tracking changes using PUSCH transmissions 225 with uplink shared data and PUSCH transmissions 225 with digital (e.g., non-analog) CSI. In some cases, the UE 115-a may receive, from the network entity 105-a, a configuration for a different power control loop for PUSCH transmissions 225 with analog CSI.
[0089] The second parameter set (e.g., for analog CSI) may include a full power transmission parameter. The full power transmission parameter may function as a switch that indicates that the UE 115-a is to transmit the PUSCH transmission 225 using a threshold (e.g., a maximum) configured transmit power irrespective of pathloss. In some cases, based on the parameter, the UE 115-a may support a DCI based dynamic switch between full power transmission and open-loop power control for PUSCH transmission that includes analog CSI.
[0090] In some cases, the UE 115-a may be configured with a first threshold (e.g., maximum) transmit power associated with non-analog CSI (e.g., associated with the first parameter set) . The UE 115-a may further be configured with a second threshold (e.g., maximum) transmit power associated with analog CSI (e.g., associated with the second parameter set) . In some examples, the first threshold may be equal to or may be different from the second threshold. That is, the UE 115-a may report a different allowed maximum power reduction (MPR) for analog CSI over PUSCH (e.g., compared to an allowed MPR for non-analog CSI) . In some cases, the configuration 215 may indicate the first threshold, the second threshold, or both.
[0091] In some implementations, the UE 115-a may transmit, in the PUSCH transmission 225, a power headroom report (PHR) . In some cases, the UE 115-a may transmit the PHR in a same subframe as an analog CSI. The PHR may be based on the actual PUSCH transmission 225 that includes analog CSI. In some examples, the PHR may indicate that, or whether, an analog CSI transmission (e.g., the PUSCH transmission 225) satisfies a configured threshold (e.g., maximum) transmit power for analog CSI (e.g., the second threshold) . The network entity 105-a may use the PHR to determine whether to adapt (e.g., adjust) a quantity of active taps for channel coefficient reporting, (e.g., more weak taps can be reported when the PHR indicates the current analog CSI transmission is below the configured threshold) .
[0092] For carrier aggregation or dual connectivity, the UE 115-a may determine a power reduction priority for the PUSCH transmission 225 carrying analog CSI as with a second power reduction priority for a second PUSCH transmission 225 that is devoid of analog CSI. However, to determine a total transmit power in a symbol of a transmission occasion for analog CSI, the UE 115-a may assume that all symbols of a same transmission occasion have a same transmit power.
[0093] FIG. 3 shows an example of a flow diagram 300 that supports power control for analog CSI over an uplink shared channel in accordance with one or more aspects of the present disclosure. The flow diagram 300 may implement or may be implemented by aspects of FIGs. 1 and 2. For example, a UE 115 may perform a procedure represented by the flow diagram 300 and may receive signaling from a network entity 105. In the following description of the flow diagram 300, the operations between the UE 115 and the network entity 105 may be performed in a different order than the example order shown. Some operations may also be omitted from the flow diagram 300, and other operations may be added to the flow diagram 300 (e.g., operations described with reference to FIGs. 2, 4A, 4B, and 5) . Further, although some operations or signaling may be shown to occur at different times for discussion purposes, these operations may actually occur at the same time.
[0094] At 305, the UE 115 may receive a configuration (e.g., the configuration 215 as described with reference to FIG. 2) from a network entity 105. The configuration may include a power control parameter set for analog CSI over PUSCH. In some cases, the configuration may indicate a list that includes a target receive power and a threshold (e.g., a maximum) transmit power for a PUSCH transmission that includes analog CSI. In some cases, the UE 115 may receive a DCI message from the network entity 105. In some examples, the DCI message may indicate the configuration.
[0095] At 310, the UE 115 may determine whether the DCI indicates full power for analog CSI transmission. That is, the DCI may indicate that the UE 115 is to transmit the PUSCH transmission (e.g., the analog CSI) with full (e.g., a maximum) transmit power. Additionally, or alternatively, the DCI may indicate that the UE 115 is to transmit the PUSCH transmission using a configured or calculated (e.g., less than maximum) transmit power.
[0096] At 315, if the DCI did not indicate full power for analog CSI transmission, the UE 115 may determine a target receive power for analog CSI based on one or more factors. For example, the one or more factors may include an indication from the network entity 105, a measured SNR, feedback channel coefficients, or any combination thereof.
[0097] At 320, the UE 115 may determine a dynamic power control adjustment offset for analog CSI based on one or more factors. For example, the one or more factors may include an indication from the network entity 105, or feedback channel coefficients (e.g., channel coefficients to feedback) , or both. In some cases, the UE 115 may calculate the dynamic power control adjustment offset (e.g., a dynamic power offset) as described with reference to FIGs. 4A and 4B.
[0098] At 325, the UE 115 may calculate a transmit power for the PUSCH transmission (e.g., to transmit the analog CSI) . The UE 115 may calculate the transmit power using the dynamic power control adjustment offset, one or more parameters indicated in the configuration, or any combination thereof. At 330, the UE 115 may transmit the PUSCH transmission (e.g., including the analog CSI) with the calculated, or adjusted, transmit power (e.g., the transmit power requested by the network entity 105) .
[0099] At 335, if the DCI indicated full power for analog CSI transmission, the UE 115 may transmit the PUSCH transmission (e.g., including the analog CSI) with full transmit power (e.g., according to a threshold, such as a maximum, transmit power associated with analog CSI) .
[0100] FIG. 4A shows an example of a flow diagram 400 that supports power control for analog CSI over an uplink shared channel in accordance with one or more aspects of the present disclosure. The flow diagram 400 may implement or may be implemented by aspects of FIGs. 1–3. For example, a UE 115 may perform a procedure represented by the flow diagram 400 and may receive signaling from a network entity 105. In the following description of the flow diagram 400, the operations between the UE 115 and the network entity 105 may be performed in a different order than the example order shown. Some operations may also be omitted from the flow diagram 400, and other operations may be added to the flow diagram 400 (e.g., operations described with reference to FIGs. 2, 3, and 5) . Further, although some operations or signaling may be shown to occur at different times for discussion purposes, these operations may actually occur at the same time.
[0101] The UE 115 may adapt a transmit power spectral density for analog CSI over PUSCH according to a set of reported channel coefficients. For example, the adaptation of the transmit power spectral density for analog CSI may be similar or analogous to an MCS factor for PUSCH. The flow diagram 400 includes a procedure 405 (performed by the UE 115) , which may be based on a hypothesized quadrature amplitude modulation (QAM) signal. The procedure 405 may take, as input, a set of analog channel coefficients 410-a and a threshold 415 (e.g., an error threshold associated with quantization error) . The UE 115 may determine the threshold 415 for the hypothesized QAM signal. For example, the threshold 415 may be configured by a higher layer or based on a compression loss, which is a sum power of unreported channel taps (e.g., γ=∑|hi|2) .
[0102] At 420, the UE 115 may select a hypothesized QAM signal. At 425, the UE 115 may determine a quantization error of the hypothesized QAM signal. At 430, the UE 115 may compare the quantization error with the threshold 415 (e.g., error threshold) . The UE 115 may repeat 420, 425, and 430, thus selecting a hypothesized QAM signal such that a total quantization loss is lower than (e.g., less than, or smaller than) the threshold 415 (e.g., such that γ=∑|hi-QAM (hi) |2<γ) . A constellation size of a QAM signal may be given by Qm, which may be an output of the procedure 405.
[0103] At 435, the UE 115 may use an equation (e.g., ) to compute (e.g., calculate) a dynamic power offset 440-a. The UE 115 may thus apply the dynamic power offset 440-a to the transmit power for a PUSCH transmission (e.g., including analog CSI) .
[0104] FIG. 4B shows an example of a flow diagram 401 that supports power control for analog CSI over an uplink shared channel in accordance with one or more aspects of the present disclosure. The flow diagram 401 may implement or may be implemented by aspects of FIGs. 1–3. For example, a UE 115 may perform a procedure represented by the flow diagram 401 and may receive signaling from a network entity 105. In the following description of the flow diagram 401, the operations between the UE 115 and the network entity 105 may be performed in a different order than the example order shown. Some operations may also be omitted from the flow diagram 401, and other operations may be added to the flow diagram 401 (e.g., operations described with reference to FIGs. 2, 3, and 5) . Further, although some operations or signaling may be shown to occur at different times for discussion purposes, these operations may actually occur at the same time.
[0105] The UE 115 may adapt a transmit power spectral density for analog CSI over PUSCH according to a set of reported channel coefficients. For example, the adaptation of the transmit power spectral density for analog CSI may be similar or analogous to an MCS factor for PUSCH. The flow diagram 401 may represent a procedure that is based on a power difference between channel coefficients with an upper threshold (e.g., highest) amplitude and a lower threshold (e.g., lowest) amplitude. For example, a dynamic power offset 440-b may be a function of the power difference.
[0106] At 445, the UE 115 may calculate an absolute value of an amplitude corresponding to each analog channel coefficient of a set of analog channel coefficients 410-b. Then, the UE 115 may determine a MAX amplitude value 450 (e.g., the upper threshold value) and a MIN amplitude value 455 (e.g., the lower threshold value) . At 460, the UE 115 may calculate a power difference (e.g., in linear or dB domain) between the MAX amplitude value 450 and the MIN amplitude value 455 (e.g., subtracting the MIN amplitude value 455 from the MAX amplitude value 450) . At 465, the UE 115-a may determine the dynamic power offset 440-b using a look-up table. The look-up table may be stored at the UE, and in some cases, the UE 115-a may receive the look-up table (e.g., as part of a configuration) .
[0107] FIG. 5 shows an example of a process flow 500 that supports power control for analog CSI over an uplink shared channel in accordance with one or more aspects of the present disclosure. The process flow 500 includes a UE 115-b and a network entity 105-b, which may be examples of the corresponding devices as described with respect to FIGs. 1–4B. In the following description of the process flow 500, the operations between the UE 115-b and the network entity 105-b may be performed in a different order than the example order shown. Some operations may also be omitted from the process flow 500, and other operations may be added to the process flow 500. Further, although some operations or signaling may be shown to occur at different times for discussion purposes, these operations may actually occur at the same time.
[0108] At 505, the UE 115-b may receive a first configuration comprising a first power control parameter set and a second power control parameter set. The first power control parameter set may be for PUSCH transmissions that are devoid of analog CSI. The second power control parameter set may be different than the first power control parameter set and may be for PUSCH transmissions that comprise analog CSI.
[0109] In some cases, the second power control parameter set may include a first power offset value that is not UE-specific, a set of one or more UE-specific power offset values, and a value of a pathloss compensation parameter that is associated with full pathloss compensation. In some examples, the second power control parameter set may support use of a maximum configured transmit power for PUSCH transmissions that include analog CSI. The maximum configured transmit power for PUSCH transmissions that include analog CSI may be different from a second maximum configured transmit power associated with one or more other types of uplink transmissions.
[0110] At 510, the UE 115-b may receive a second parameter set indication. The second parameter set indication may indicate that the second power control parameter set is to be used for PUSCH transmissions that include analog CSI and further include uplink shared channel data, digital CSI, or both.
[0111] At 515, the UE 115-b may receive downlink signaling that indicates a UE-specific offset value from among the set of one or more UE-specific power offset values. In some cases, the downlink signaling may be or may include a DCI message or another downlink message. Additionally, or alternatively, at 520, the UE 115-b may select a UE-specific offset value from among the set of one or more UE-specific power offset values based on a downlink SNR, one or more channel coefficients included in the first set of analog CSI, or any combination thereof.
[0112] At 525, the UE 115-b may determine, based on the PUSCH transmission including the first set of analog CSI, a dynamic offset (e.g., a dynamic power offset value) using an iteration loop that is based on a BLER associated with decoding a PDSCH message that corresponds to the analog CSI. In some cases, the UE 115-b may decrease the dynamic offset based on a successful decoding of the PDSCH message (e.g., an ACK) . The UE 115-b may increase the dynamic offset based on an unsuccessful decoding of the PDSCH message (e.g., a NACK) .
[0113] At 530, the UE 115-b may receive a DCI message that includes a transmit power control indicator value. In some cases, the first configuration may include a transmit power control indicator value (e.g., in one or more parameter sets of the first configuration) .
[0114] At 535, the UE 115-b may determine, based on the PUSCH transmission including the first set of analog CSI and further based on a carrier aggregation or dual connectivity configuration for the UE, a power reduction priority for the PUSCH transmission based on an assumption that each symbol of a set of symbols associated with the PUSCH transmission have a same transmit power.
[0115] At 540, the UE 115-b may transmit a PUSCH transmission that includes a first set of analog CSI. In some cases, the UE 115-b may transmit the PUSCH transmission using a transmit power. The transmit power may be based on the second power control parameter set. In some cases, the transmit power may be based on the UE-specific offset value (e.g., indicated at 515 and / or selected at 520) . Additionally, or alternatively, the transmit power may be based on the dynamic offset (e.g., determined at 525) . The transmit power may be further based on the transmit power control indicator value (e.g., received at 530) . In some examples, transmitting the PUSCH transmission using the transmit power may be further based on the PUSCH transmission being devoid of uplink shared channel data.
[0116] In some cases, the first set of analog CSI may include multiple channel coefficients corresponding to multiple (e.g., respective) channel taps. The multiple channel coefficients included in the first set of analog CSI may not be quantized prior to being transmitted via the PUSCH transmission. That is, the UE 115-b may refrain from quantizing the first set of analog CSI prior to transmitting the PUSCH transmission.
[0117] In some implementations, the PUSCH transmission may include uplink shared channel data, digital CSI, or both. Transmitting the PUSCH transmission using the transmit power may be based on receipt of the second parameter set indication (e.g., the indication received at 510) .
[0118] In some cases, if the PUSCH transmission includes the first set of analog CSI, a transmit power spectral density for the PUSCH transmission may be based on one or more channel coefficients included in the first set of analog CSI. In some examples, the transmit PSD for the PUSCH transmission may be based on a comparison between an error threshold and a quantization error associated with quantizing the first set of analog CSI (e.g., as described with reference to FIG. 4A) . Quantizing the first set of analog CSI may be in accordance with a QAM scheme (e.g., as described with reference to FIG. 4A) . Additionally, or alternatively, the transmit PSD for the PUSCH transmission may be based on a difference in power between a largest channel coefficient included in the first set of analog CSI and a smallest channel coefficient included in the first set of analog CSI (e.g., as described with reference to FIG. 4B) .
[0119] In some implementations, the UE 115-b may transmit, in a same subframe as the first set of analog CSI, a PHR for the first set of analog CSI. The PHR may be based on the PUSCH transmission. In some cases, the PHR may indicate whether the transmit power is less than or equal to a maximum configured transmit power (e.g., supported by the second power control parameter set) for PUSCH transmissions that include analog CSI.
[0120] At 545, the UE 115-b may transmit a second PUSCH transmission that is devoid of analog CSI. In some cases, the UE 115-b may transmit the second PUSCH transmission using a second transmit power that is based at least in part on the first power control parameter set.

[0127] In some examples, the communications manager 620 may be configured to perform various operations (e.g., receiving, obtaining, monitoring, outputting, transmitting) using or otherwise in cooperation with the receiver 610, the transmitter 615, or both. For example, the communications manager 620 may receive information from the receiver 610, send information to the transmitter 615, or be integrated in combination with the receiver 610, the transmitter 615, or both to obtain information, output information, or perform various other operations as described herein.

[0153] In some examples, the first set of analog CSI includes a set of multiple channel coefficients corresponding to a set of multiple channel taps. In some examples, the set of multiple channel coefficients included in the first set of analog CSI is not quantized prior to being transmitted via the PUSCH transmission.
