Abstract: A passive multiple-input multiple-output (P-MIMO) method that may be performed by a reconfigurable intelligent surface (RIS) includes applying a first voltage set to one or more unit cells of the RIS for reflecting a downlink signal from a first wireless communication device to a second wireless communication device. The method includes applying a second voltage set to the one or more unit cells of the RIS for reflecting an uplink signal from the second wireless communication device to the first wireless communication device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive signaling to operate in a radio resource control (RRC) inactive or idle state. The UE may receive a phase tracking reference signal (PTRS) configuration for a physical downlink shared channel (PDSCH) or physical uplink shared channel (PUSCH) communication when the UE is operating in the RRC inactive or idle state. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive, from a base station, a first downlink control information (DCI) message of a two-stage set of DCI. The UE may receive, from the base station, a second DCI message of the two-stage set of DCI. The UE may select between the first DCI message and the second DCI message as a timing reference point. In some examples, the UE may receive, from the base station, downlink data on the physical downlink channel. In some examples, the UE may transmit, to the base station, an uplink data message on the physical uplink channel.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit configuration signaling such as radio resource control (RRC) signaling to a user equipment (UE) which indicates a number of sounding reference signal (SRS) resource sets and respective SRS resources within each of the SRS resource sets that may be used for channel estimation. The base station may subsequently transmit a control message such as a medium access control (MAC) control element (CE) to the UE, which indicates an activation status for at least one SRS resource within the SRS resource set. Basedon the indicated activation status for the at least one SRS resource, the UE may transmit one or more SRSs to the base station.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiving device may transmit, to a transmitting device, a line of sight (LOS) multiple input multiple output (MIMO) channel sounding configuration that indicates one or more channel sounding parameters for a partial sounding procedure associated with an LOS MIMO channel. The receiving device may receive, from the transmitting device, at least one sounding reference signal (SRS) based at least in part on the one or more channel sounding parameters. Numerous other aspects are described.

Abstract: Aspects of the disclosure relate to utilizing SRS resources for various types of usages and configuring transmit power on the SRS resources. In an aspect, a user equipment (UE) may determine whether a time gap between a first sounding reference signal (SRS) resource for a first usage and a second SRS resource for a second usage in time is less than a time threshold. Further, the UE may transmit an SRS utilizing one of the first SRS resource or the second SRS resource for both the first usage and the second usage, in response to determining that the time gap is less than the time threshold.

Abstract: A network node may transmit a CSI-RS to a UE. The UE may transmit a CSI report corresponding to at least one UE-selected bandwidth portion of a downlink BWP to the network node based on the CSI-RS. The CSI report may include at least one CQI for the at least one UE-selected bandwidth portion of the downlink BWP. The downlink BWP may be associated with a full-duplex operation.
