Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a sounding reference signal (SRS) that indicates that the UE is configured with a quantity of receive elements that is greater relative to a quantity of transmit elements with which the UE is configured. The UE may receive, based at least in part on transmitting the SRS, a first channel state information (CSI) reference signal (CSI-RS) set and a second CSI-RS set. The UE may transmit a CSI report that is based at least in part on the first CSI-RS set and the second CSI-RS set. Numerous other aspects are provided.

Abstract: Aspects of the present disclosure provide techniques for transmitting an uplink preemption indication in an integrated access and backhaul (IAB) system identifying the resources or symbols that may be punctured by the IAB in order to minimize self-interference at an IAB node when an ultra-reliable-low latency communications (URLLC) packet is received at the IAB node from one of a child IAB node or a user equipment (UE) during an on-going uplink transmission from an IAB node to a parent backhaul node.

Abstract: Methods, systems, and devices for wireless communications are described for enabling a network equipment to reduce interference for downlink (DL) transmissions to a first device by determining a transmit precoding matrix indicator (TPMI) for uplink (UL) transmissions transmitted by a second device based on feedback from the first device. The first device may determine a subset of possible TPMIs that the second device may use for UL transmissions for full-duplex communications. The first device may indicate the subset to the network equipment. Based on the subset indicated by the first device, the network equipment may determine a pairing of the first device and the second device for full-duplex communications. Additionally, the network equipment may determine a TPMI for the second device to use in UL transmissions and indicate the TPMI to the second device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information for an uplink control channel, wherein the configuration information includes at least one of: a first resource identifier associated with a non-full-duplex (non-FD) zone, or a second resource identifier associated with a full-duplex (FD) zone. The UE may transmit uplink control information (UCI) on the uplink control channel in at least one of the non-FD zone or the FD zone in accordance with the configuration information. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a sounding reference signal (SRS) configuration that indicates a maximum number of SRS ports and whether the UE is permitted to determine an actual number of SRS ports to be used for SRS transmission that is different from the maximum number of SRS ports. The UE may determine the actual number of SRS ports to be used for SRS transmission based at least in part on the SRS configuration. The UE may transmit one or more SRSs using the actual number of SRS ports. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, configuration information regarding one or more available slots associated with transmitting sounding reference signal (SRS) information. The UE may receive, from the base station, dynamic downlink communication including slot information for determining a select available slot from among the one or more available slots. The UE may transmit, to the base station, the SRS information during the select available slot, determined based at least in part on the slot information and the configuration information. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a node may determine a first set of time-frequency resources, within a time duration, for full-duplex communications and a second set of time-frequency resources, within the time duration, for non-full-duplex communications. The node may transmit to a wireless communication device and based at least in part on determining the first set of time-frequency resources and the second set of time-frequency resources, an indication of the first set of time-frequency resources, the second set of time-frequency resources, and corresponding transport formats for the first set of time-frequency resources and the second set of time-frequency resources. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for scheduling hybrid automatic repeat request (HARQ) feedback and controlling the transmit power of the HARQ feedback. An example method generally includes generating a configuration for physical uplink control channel (PUCCH) resource sets assigned to at least one user equipment (UE), wherein each of the PUCCH resources sets comprises PUCCH resources, transmitting the configuration for the PUCCH resource sets to the at least one UE, generating an uplink control reporting indication indicating the PUCCH resources associated with downlink demodulation reference signal (DMRS) port groups, transmitting the uplink control reporting indication, to the at least one UE, for use in reporting uplink control information (UCI), and receiving at least a part of the UCI associated with at least one of the downlink DMRS port groups from the at least one UE via the PUCCH resources indicated in the uplink control reporting indication.

Abstract: Certain aspects of the present disclosure provide techniques for multiplexing uplink control information (UCI) on physical uplink control channel (PUCCH) resources for non-ideal backhaul based multi-transmission/reception point non-coherent joint transmissions. An example method generally includes determining that a first set of physical uplink control channel (PUCCH) resources configured for reporting channel state information (CSI) overlaps with a second set of PUCCH resources indicated for reporting hybrid automatic repeat request (HARQ) feedback, wherein the first and second sets of PUCCH resources are associated with downlink demodulation reference signal (DMRS) port groups, generating CSI reports and HARQ feedback associated with at least one of the downlink DMRS port groups, and transmitting the CSI reports and the HARQ feedback, multiplexed using the second set of PUCCH resources
