Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a network entity may receive a sounding reference signal (SRS) at a multi-panel system of the network entity, where the multi-panel system includes one or more sounded panels and one or more non-sounded panels. The network entity may estimate a channel to obtain channel state information (CSI) for the one or more sounded panels based at least in part on the SRS. The network entity may estimate CSI for the one or more non-sounded panels based at least in part on the CSI for the one or more sounded panels. The network entity may transmit or receive a communication based at least in part on the CSI for the one or more sounded panels and the CSI for the one or more non-sounded panels. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit feedback to a base station indicating phase values for sub-bands in a bandwidth part (BWP). The base station may use the phase feedback to perform precoding on a set of beams. To support a reduced payload overhead for the feedback, the UE may implement differential phase feedback. For example, the UE may divide the BWP into a number of sub-band groups and may generate, for each sub-band group of each beam, a first set of bits indicating an absolute phase value for a first sub-band of the sub-band group. The UE may additionally generate a second set of bits indicating differential phase values for the other sub-bands of each sub-band group. The UE may report the first and second sets of bits for the beams to the base station for precoding.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may perform channel state information (CSI) measurements on one or more reference signal transmissions received from a base station. Based on the CSI measurements, the UE may generate a CSI report, and the UE may transmit the CSI report to the base station. In some cases, the generated CSI report may include a first portion and a second portion. The first portion may indicate whether the second portion of the CSI report includes full-band CSI feedback or partial-band CSI feedback. The second portion may provide the CSI feedback for one or more identified sub-bands. In some cases, the second portion may include a sub-band index indicating the identified sub-bands. Additionally or alternatively, the second portion may include a bitmap indicating a correspondence between multiple CSI feedback values and multiple corresponding sub-band indexes.

Abstract: In some circumstances, a URLLC may preempt resource. An apparatus may be configured to receive a set of resource blocks from a base station including at least one of eMBB data or URLLC data in a PDSCH. The apparatus may receive a URLLC indicator from the base station. The URLLC indicator may be received embedded within the URLLC data or received separate from the URLLC data within DCI of a PDCCH. The URLLC indicator indicates whether the set of resource blocks includes at least part of the URLLC data. The apparatus may determine, based on the URLLC indicator, whether the set of resource blocks includes the URLLC data and processing the set of resource blocks based on a result of determining whether the set of resource blocks includes the URLLC data.

Abstract: Aspects directed towards new radio (NR) transmissions of uplink control information (UCI) are disclosed. In a particular example, a priority is assigned to each of a plurality of UCI components such that the priority is assigned according to at least one of a type or payload size respectively associated with each of the plurality of UCI components. The plurality of UCI components are then transmitted based on the priority respectively assigned to each of the plurality of UCI components.

Abstract: Certain aspects of the present disclosure provide techniques for uplink control information (UCI) transmission for overlapping physical uplink shared channel (PUSCH) and physical uplink control channel (PUCCH) resource assignments with repetition. A method of wireless communication by a user equipment (UE) is provided. The method generally includes receiving scheduling to transmit on the PUSCH in a first one or more slots associated with a first number of repetitions and scheduling to transmit on the PUCCH in a second one or more slots associated with a second number of repetitions. The scheduled transmissions overlap in at least one slot. The method includes determining which channel to transmit UCI on and which channel to drop for each of the first and second one or more slots. The method includes transmitting or dropping the UCI in the first and second one or more slots in accordance with the determination.

Abstract: Aspects of the present disclosure provide for opportunistic uplink transmissions within a slot. In some examples, after scheduling all regular uplink transmissions within a current slot, a base station (e.g., gNB) may identify a set of unused uplink resources within the current slot and generate and transmit unused resource information identifying the set of unused resources to the user equipment (UE) within the cell served by the base station. If a particular UE is configured to operate in an opportunistic mode, the UE may utilize the unused resource information to generate and transmit an opportunistic uplink transmission within the set of unused uplink resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may identify a transmit power control (TPC) command, associated with the UE, based at least in part on group power control downlink control information (DCI); and determine a loop index associated with the TPC command, wherein the loop index identifies a power control loop, of a plurality of power control loops, for the TPC command. In some aspects, the UE may apply the TPC in association with transmitting an uplink communication, wherein a time gap between receiving the group power control DCI and applying the TPC command is based at least in part on a capability value associated with the UE, or a delay value signaled to the UE. Numerous other aspects are provided.
