Abstract: Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may receive, from a network entity, information indicating one or more of sounding reference signal (SRS) ports selected by the network entity and associated linear combination coefficients, determine subband precoding based at least in part on the selected SRS ports and linear combination coefficient, and transmit a physical uplink shared channel (PUSCH) with the subband precoding.

Abstract: Methods, systems, and devices for wireless communications are described. The method includes receiving, from a base station, downlink control information indicating at least a portion of a frequency domain basis vector being applied by the base station for frequency domain precoding of a reference signal scheduled for transmission via a set of antenna ports, receiving, from the base station, the reference signal that is frequency domain precoded in accordance with the at least portion of the frequency domain basis vector via the set of antenna ports, and transmitting, to the base station, a report indicating an antenna port subset of the set of antenna ports and a precoding coefficient for each antenna port of the antenna port subset.

Abstract: Certain aspects of the present disclosure provide techniques for using subband precoding for uplink transmissions. In some cases, a UE may transmit sounding reference signals (SRS) to a network entity, receive information indicating at least one of a set of one or more frequency domain (FD) bases and linear combination coefficients, determined based on the SRS transmission, determine subband precoding based at least in part on linear combinations of the FD bases based on the linear combination coefficients, and transmit a physical uplink shared channel (PUSCH) with the subband precoding.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive a configuration message from a base station, and the configuration message may include an indication of one or more partial bands for channel state information reporting. Each partial band of the one or more partial bands may be less than a system bandwidth and include a plurality of frequency domain units associated with a precoder. The UE may select one or more antenna ports for each partial band of the one or more partial bands based on the configuration message and calculate channel state information including a linear combination of the selected one or more antenna ports for each partial band. The UE may transmit the channel state information including an indication of the selected antenna ports and linear combination coefficients for each partial band of the one or more partial bands

Abstract: Methods, systems, and devices for wireless communications are described. The methods, systems, and devices may enable a user equipment (UE) to receive a sounding reference signal (SRS) configuration message that indicates one or more first reference signals from a first node or one or more SRS transmission beams associated with the first node and one or more second reference signals from a second node. The UE may determine an SRS transmission beam for transmitting an SRS signal based on a procedure for determining SRS transmission beams and the one or more reference signals from the first and second nodes. The UE may transmit the SRS signal using the SRS transmission beam.

Abstract: Methods, systems, and devices for wireless communications are described in which a base station operating in full-duplex mode may provide for reception of one or more higher priority transmissions using at least partially overlapping time-frequency resources as used for transmission of lower priority communications. In order to mitigate self-interference at the base station, a transmission power used for the overlapping time-frequency resources may be reduced. The base station may provide an indication of a subset of resources that have a reduced transmission power, an amount of the power reduction for the subset of resources, or both.

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: 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.
