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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that indicates a sounding reference signal (SRS) resource set to be used for analog channel state feedback (CSF) and an association between the SRS resource set and a set of downlink channel state information reference signals (CSI-RSs). The UE may measure the set of downlink CSI-RSs associated with the SRS resource set. The UE may transmit one or more SRSs for analog CSF using the SRS resource set and based at least in part on measuring the set of downlink CSI-RSs. 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: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling from a network entity scheduling a set of multiple periodic tracking reference signals (TRSs) and indicating a transmission power level for the periodic TRSs. For example, the control signaling may be received via radio resource control (RRC). The UE may receive a downlink control information (DCI) message from the network entity indicating an adjustment to the transmission power level and a resource for an aperiodic TRS. The UE may monitor the resource for the aperiodic TRS in accordance with the indicated adjustment to the transmission power level. The UE may transmit a message to the network entity indicating a measurement of the aperiodic TRS based on the adjustment to the power level. The adjustment to the power level may apply to one or more of the set of multiple periodic TRSs.

Abstract: A first user equipment (UE) for wireless communication may be configured to send, to a second UE, a plurality of sidelink reference signals (SL-RSs), wherein the first UE and the second UE are configurable to communicate with a network entity, and wherein the plurality of SL-RSs includes a first SL-RS corresponding to a first operational state of the network entity. The first UE may receive, from the second UE, one or more channel state information (CSI) reports, wherein each CSI report of the one or more CSI reports corresponds to a respective SL-RS of the plurality of SL-RSs.
