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: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station (BS) may identify a collision between a data transmission and a demodulation reference signal (DMRS) transmission in a full-duplex time-frequency resource. The BS may transmit, to a wireless communication device, an indication of a time-frequency mapping for a zero-power DMRS (ZP-DMRS) in the full-duplex time-frequency resource. The time-frequency mapping for the ZP-DMRS, and a time-frequency mapping in the full-duplex time-frequency resource for the DMRS transmission, may be a same time-frequency mapping. Numerous other aspects are provided.

Abstract: Certain aspects of the present disclosure provide techniques for a user equipment (UE) to determine channel state information (CSI) to feedback to a base station (BS) in a full-duplex wireless communications system while considering UE-to-UE interference and for the BS to configure the UE to provide the CSI to the BS. In an exemplary method, a UE receives, from a base station (BS) in a full-duplex communications system, a channel state information (CSI) report configuration including at least a first indicator of a first associated set of sounding reference signal (SRS) resources; and transmits to the BS a CSI report including CSI and zero or more second indicators of sets of measured SRS resources.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a dynamic indication of a transmission power difference between a reference signal and a downlink shared channel for a full-duplex zone. The UE may determine channel state information (CSI) based at least in part on the dynamic indication of the transmission power difference between the reference signal and the downlink shared channel for the full-duplex zone. The UE may transmit a CSI report that identifies the CSI. Numerous other aspects are provided.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may perform channel state information (CSI) measurements on one or more reference signal transmissions from a base station; determine, based at least in part on the CSI measurements, a set of non-zero linear combination complex coefficients for weighting and co-phasing for a linear combination of a plurality of frequency domain basis vectors and a plurality of spatial domain basis vectors; and transmit a CSI feedback, wherein a first part of the CSI feedback includes at least an indication of a number of the set of non-zero linear combination complex coefficients with regard to all layers of a communication link between the UE and the base station. Numerous other aspects are provided.

Abstract: Various embodiments may provide communication security at a physical layer. In some embodiments, a first wireless device at a first location may transmit to a second wireless device at a second location different portions of a message via two or more different spatially separated signal paths in a manner that enables the second wireless device to receive the complete message but prevents reception of the complete message by a third wireless device at a third location different from the second location. The second wireless device may receive different portions of the message via the two or more different spatially separated signal paths, may assemble the message from the received different portions of the message.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive from a network entity, a control message triggering the UE to provide a time-domain aperiodic channel state information (A-CSI) report for indicating time-domain channel state information (CSI) associated with CSI reference signal (CSI-RS) resources within an observation window, where a beginning of the observation window is based on when the control message is received. The UE may perform performing measurements of channel state information reference signals (CSI-RSs) received via the CSI-RS resources that occur within the observation window. The UE may then transmit, to the network entity based on the control message, the time-domain A-CSI report indicating measured time-domain CSI associated with the observation window, where the measured time-domain CSI is based on the measurements.
