Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a base station may perform one or more operations for receive antenna switching. For example, a UE may receive a set of reference signals from a base station using one or more ports of the UE. Based on receiving the set of reference signals, the UE may generate channel state information (CSI) associated with a set of antenna ports. In some cases, the UE may generate CSI based on receiving a configuration indicating the set of antenna ports. The UE may transmit, to the base station, a CSI report including the CSI information associated with the set of antenna ports and an indication of the associated antenna ports. The base station may receive the CSI report and may communicate with the UE using a set of precoders associated with the set of indicated antennas ports.

Abstract: Apparatus, methods, and computer-readable media for facilitating CSI feedback in multiple-TRP communication are disclosed herein. An example method of wireless communication by a UE includes receiving, from a base station, a report configuration message triggering a channel state feedback procedure, the UE and the base station operating in a multiple transmission and reception point (multiple-TRP) communication mode, the report configuration message requesting a multiple-TRP transmission value including at least one of a quantity of layer indicator (LI) values and a strongest TRP indicator (STI) value. The example method also includes generating channel state information (CSI) information based on the receiving of the report configuration message, the CSI information including the multiple-TRP transmission value. The example method also includes transmitting, to the base station, a report including the generated CSI information.

Abstract: Aspects of the disclosure relate to control of discovery signal transmissions for D2D communication. A first UE may transmit a discovery signal initiation message to at least a second UE to control transmission of a discovery signal from the second UE to a third UE. The second UE may identify a discovery signal monitoring duration of the second UE during which the second UE monitors for transmitted discovery signals transmitted from other UEs to the third UE. At expiration of the discovery signal monitoring duration, the second UE may transmit a discovery signal to the third UE when the number of transmitted discovery signals transmitted from the other UEs during the discovery signal monitoring duration is less than a discovery signal transmission number threshold.

Abstract: Aspects described herein relate to receiving a configuration indicating a first codebook subset restriction table restricting a set of precoding matrix indicators (PMIs) for which PMI feedback is to be reported for an antenna array, generating, based on the configuration, PMI feedback for an adaptive configuration of the antenna array based on a second codebook subset restriction table for the adaptive configuration of the antenna array, and transmitting the PMI feedback to the base station. Other aspects relate to transmitting the configuration and/or receiving the PMI feedback.

Abstract: Disclosed are techniques for wireless communication. In an aspect, a user equipment (UE) may receive an announcement message from each sidelink anchor device of one or more sidelink anchor devices, wherein the announcement message includes a sidelink anchor device identifier and an indication that the sidelink anchor device is available for positioning services. The UE may measure the announcement message from each sidelink anchor device to determine a signal strength measurement associated with the sidelink anchor device. The UE may report, to a network node, one or more preferred sidelink anchor devices from the one or more sidelink anchor devices, wherein the one or more preferred sidelink anchor devices are determined based on the signal strength measurement respectively associated with each sidelink anchor device of the one or more sidelink anchor devices.

Abstract: Disclosed are techniques for communication. In an aspect, a position estimation entity determines a sidelink positioning reference signal (SL-PRS) resource configuration associated with a positioning measurement procedure. The position estimation entity transmits an indication of the SL-PRS resource configuration (e.g., to first and/or second UEs). The UE(s) obtain the SL-PRS resource configuration, and perform the positioning measurement procedure in accordance with the SL-PRS resource configuration.
