Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive configuration information that specifies one or more parameters associated with generating, by the UE, a time domain covariance matrix specific to the UE. The UE may receive a channel state information (CSI) reference signal (CSI-RS). The UE may transmit, based at least in part on the CSI-RS and the one or more parameters, a CSI report, the CSI report including data representing the time domain covariance matrix. Numerous other aspects are described.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a user equipment (UE) may identify, in a radio frequency spectrum band a first resource for a sidelink synchronization signal block (S-SSB) and may perform a channel access procedure for the radio frequency spectrum band for the first resource. In a first example, a second resource for a sidelink message may overlap in time with the first resource and the UE may perform the channel access procedure based on the S-SSB being prioritized over the sidelink message. In a second example, the UE may perform the channel access procedure in accordance with a first value of a parameter for the channel access procedure associated with a first synchronization priority based on the UE being associated with the first synchronization priority. The UE may transmit an S-SSB over the first resource based on the channel access procedure indicating availability.

Abstract: Various aspects of the present disclosure generally relate to orbital angular momentum (OAM) multiplexing based communication. In some aspects, a transmitter of OAM multiplexing based communication may determine an azimuth mode configuration for transmitting a data stream, wherein the azimuth mode configuration indicates one or more azimuth modes. The transmitter may transmit, to a receiver of the OAM multiplexing based communication, the data stream based at least in part on the azimuth mode configuration. Numerous other aspects are described.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to procedures for supporting conditional new radio (NR) secondary node (SN) addition and change by reusing conditional handover (CHO) procedures. In some aspects, the procedures include a method for wireless communications by a master node (MN), comprising identifying a set of candidate cells for a conditional addition or change as an SN for a UE based on execution criteria, and signaling configuration information regarding the set of candidate cells to the UE.

Abstract: Aspects of the present disclosure provide techniques for reducing channel state information (CSI) feedback overhead sent from one or more user equipments (UEs) to a network entity, such as a base station (BS) or gNodeB (gNB), while ensuring correct mapping of the CSI feedback at the network entity. In some cases, the overhead reduction may be achieved by converting the CSI feedback to size-reduced and further quantized representative coefficients (e.g., for multiple UEs). The quantized coefficients allow the network entity to recover the CSI feedback by de-quantizing and correctly mapping the quantized coefficients to recover the CSI feedback.

Abstract: Aspects presented herein may enable a positioning entity (e.g., a UE, a base station, a TRP, or an LMF, etc.) to take changes in propagation delay into consideration when calculating RTT or measuring Rx-Tx timing difference for signals transmitted between a UE and a non-terrestrial device. In one aspect, a UE measures a plurality of PRSs transmitted from a non-terrestrial device. The UE calculates a propagation delay change between the UE and the non-terrestrial device based on a TDOA of the plurality of PRSs. The UE transmits, to an LMF or a location server, a UE Rx-Tx time difference associated with a UE positioning session and the propagation delay change.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for techniques for signaling control information in wireless communication systems based on orbital angular momentum (OAM) modes. One aspect provides a method for wireless communication by a transmitter. The method generally includes transmitting to a receiver, with a first orbital angular momentum (OAM) mode, a first control channel on a first time-frequency resource and transmitting to the receiver, with a second OAM mode, at least one of a data channel or a second control channel on a second time-frequency resource that at least partially overlap with the first time-frequency resource in at least one of time or frequency.

Abstract: In a probabilistic amplitude shaping (PAS) system, a distribution matching (DM) component may receive a uniform bit sequence with equal probabilities, which may be converted into symbols with a desired probability distribution (e.g., Gaussian). For example, the probability distribution may use inner constellation points associated with a lower energy and/or power more frequently and outer constellation points associated with a higher energy and/or power less frequently. In general, the DM component may map binary bits to positive amplitudes with a non-uniform distribution according to a DM rate that is based at least in part on a signal-to-noise ratio (SNR), which may vary significantly in a spatial and frequency selective wireless channel. Accordingly, some aspects described herein relate to configuring DM parameters and codeword and resource mappings in a spatial and frequency selective wireless channel.
