    Abstract: Certain aspects of the present disclosure provide techniques for port selection for channel state feedback with analog feedforward. A method that may be performed by a user equipment (UE) includes selecting one or more channel state information reference signals (CSI-RS) ports, of a plurality of CSI-RS ports, for the UE to report CSI. The port selection includes selecting any of the plurality of CSI-RS ports for selecting CSI-RS based on a grouping of the plurality of CSI-RS ports. The UE determines a precoding matrix indicator (PMI) formed by a linear combination of the one or more selected CSI-RS ports. The UE computes at least wideband linear combination coefficients for the selected CSI-RS ports. The UE provides the selected one or more CSI-RS ports and the computed wideband linear combination coefficients to a base station (BS) in a CSI report.

    Abstract: Methods, systems, and devices for line of sight (LOS) multiple input multiple output (MIMO) signaling aspects are described. In some examples, a wireless device may transmit, to a network device, a capability message indicating that the wireless device supports a LOS mode. In such examples, the wireless device may receive, from the network device in response to the capability message, a control message indicating activation of the LOS mode and at least one LOS mode parameter based at least in part on a channel measurement associated with a wireless channel between the wireless device and the network device indicating that the wireless channel satisfies a LOS path criterion. In some examples, the wireless device may communicate a message with the network device in accordance with the LOS mode parameter.

    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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a wireless communication device may receive an indication of a first transmit power configuration and a second transmit power configuration for a physical uplink shared channel (PUSCH) communication. The wireless communication device may transmit, using a first transmit power that is based at least in part on the first transmit power configuration, a first portion of the PUSCH communication in a full-duplex portion of a time-frequency resource. The wireless communication device may transmit, using a second transmit power that is based at least in part on the second transmit power configuration, a second portion of the PUSCH communication in a non-full-duplex portion of the time-frequency resource. Numerous other aspects are provided.
