Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may generate multiple channel state information (CSI) reports that are linked together for coherent joint transmission (CJT) with multiple transmit receive points (TRPs).

Abstract: An aerial device receives a timing advance configuration from a base station for sidelink communication with one or more user equipments (UEs), the timing advance configuration indicating an initial timing advance for the sidelink communication with the one or more UEs. The aerial device transmits a discovery message from the aerial device to the one or more UEs at a transmission time based on the initial timing advance relative to a reference time of a sidelink synchronization reference.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for techniques for wireless communications based on orbital angular momentum (OAM) modes. One aspect provides a method for wireless communications by a first wireless node. The method generally includes transmitting traffic to a user equipment (UE) on an access link, using a first portion of a uniform circular array (UCA) antenna panel and transmitting traffic to a second wireless node on a backhaul link, using a second portion of the UCA antenna panel.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may transmit a sounding reference signal (SRS) in multiple slots. A network entity may determine precoding weights in three domains based on the SRS and output reference signals that are precoded based on the precoding weights. The network entity may output control signaling that indicates reference signal resource grouping information that the UE is to use for channel estimations. The reference signal resource grouping information may specify whether the ports in one group are precoded with identical or different spatial, frequency, and time domain weights. A UE may receive the precoded reference signals and the grouping information and report estimated channel metrics and an indication of selected ports per group to the network entity. The network entity may determine precoding in three domains for subsequent downlink communications.

Abstract: A method of wireless communication by a base station includes receiving a channel state information (CSI) payload at a neural network CSI decoder. The method also includes decoding the CSI payload to generate a quantity (N) of precoding vectors for N transmission layers. The method further includes orthogonalizing the N precoding vectors to generate N orthogonal precoding vectors. The method still further includes transmitting, to a user equipment (UE), downlink data that is precoded in accordance with the N orthogonal precoding vectors.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a downlink visible light communication (VLC) transmission. The UE may receive, from the base station, a downlink New Radio (NR) radio frequency (RF)-based communication (RFC) transmission, wherein a frame structure associated with the downlink VLC transmission is asynchronous with a frame structure associated with the downlink NR RFC transmission. The UE may transmit, to the base station via an uplink RF transmission based at least in part on a lack of support for an uplink VLC transmission at the UE, acknowledgement or negative acknowledgement (ACK/NACK) feedback associated with one or more of the downlink VLC transmission or the downlink NR RFC transmission. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. A first UE may receive a message indicating a configuration or a sidelink discovery burst transmission window. The configuration may include time periods for transmitting multiple sidelink synchronization signals. The first UE may perform a channel access procedure during the sidelink discovery burst transmission window. The first UE may perform the channel access procedure for transmitting one or more of the sidelink synchronization signals according to a pattern indicated by the configuration. The pattern may be based on a quasi co-location relationship between associated pairs of the sidelink synchronization signals. The first UE may transmit the one or more sidelink synchronization signals to a second UE in accordance with the pattern indicated by the configuration.
