Abstract: Techniques for beam-based relay node switch. An example method of wireless communication by a first wireless node generally includes relaying wireless communications between a user equipment (UE)(120, 120a-y) and a network entity; transmitting, to one or more second wireless nodes, relay request signals via a plurality of beams(402a-d, 602a-d, 604a-b, 706a-b) at relay request signal occasions(1, 2, 3), wherein each of the relay request signals indicates a request to switch relay services of the UE(120, 120ay) from the first wireless node to the one or more second wireless nodes; and switching the relay services of the UE(120, 120a-y) to at least one of the one or more second wireless nodes.

Abstract: A reduced-capability user equipment (UE) uses frequency hopping to improve downlink (DL) coverage. Specifically, the UE may receive a physical downlink shared channel (PDSCH) using frequency hopping among a plurality of narrow hands in a wide bandwidth part. A bandwidth of narrow band is not larger than a maximum wireless communication bandwidth of the UE.

Abstract: Various aspects of the present disclosure generally relate to frequency hopping within a virtual BWP. In son aspects, a UE may determine a virtual bandwidth part (BWP) in which to frequency hop from a first narrow BWP to a second narrow BWP by a frequency offset. The virtual BWP may have a same subcarrier spacing as the first narrow BWP and a larger bandwidth than the first narrow BWP. The UE may perform communication based at least in part on frequency hopping within the virtual BWP. Numerous other aspects are provided.

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.

Abstract: Disclosed are techniques for communication. In an aspect, a position estimation entity (e.g., gNB, LMF, location server, UE, etc.) determines a paired downlink positioning reference signal (DL-PRS) resource configuration for a first DL-PRS and a second DL-PRS that is offset in time from the first DL-PRS by a time offset, the first and second DL-PRSs associated with the same transmission source. The position estimation entity transmits the paired DL-PRS resource configuration to a UE, which performs measurements in accordance with the paired DL-PRS resource configuration.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an assisting user equipment (UE) may determine, within a resource selection window, one or more resources to reserve in a shared resource pool for an internal sidelink transmission within a disaggregated UE group including the assisting UE and one or more assisted UEs. The assisting UE may transmit, over a sidelink, an assisting reservation message indicating a lower reference signal received power (RSRP) to project onto the one or more resources reserved for the internal sidelink transmission relative to a measured RSRP that is based at least in part on a transmit power associated with the assisting reservation message. Numerous other aspects are described.
