Abstract: Methods, systems, and devices for wireless communication are described. A first wireless device may transmit one or more signals to a second wireless device using an antenna panel including antenna elements that are arranged in a hexagonal configuration. The signals may be transmitted using one or more directional beams for multiple-input multiple-output communications with the second wireless device, the directional beams generated based on the antenna elements in the hexagonal configuration. The first wireless device may receive a signal from the second wireless device, and in some cases, the first wireless device may transmit one or more reference signals via the one or more directional beams, the reference signals associated with a set of two or more antenna elements of the antenna panel of the first wireless device. The second wireless device may perform measurements of the reference signals and transmit a measurement report to the first wireless device.

Abstract: Methods, systems, and devices for wireless communications are described. A receiving device may receive, from a transmitting device, a configuration indicating a set of orbital angular momentum (OAM) modes for joint reporting, where at least one of the set of OAM modes is associated with transmission via two or more of a plurality of sets of antennas arranged in a set of concentric circular arrays. The receiving device may transmit, to the transmitting device, a report indicating precoding information for each of at least a subset of the set of OAM modes, where the precoding information includes one or more first parameters common to the set of OAM modes and one or more second parameters for respective ones of the at least the subset of the set of OAM modes.

Abstract: In an aspect, a UE transmits an SL RTT measurement request to at least one UE. The UE communicates (e.g., transmits, receives, or both), with the at least one UE in response to the SL RTT measurement request, an indication of an SL RTT measurement (e.g., Rx-Tx time difference measurement for RTT).

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be a user equipment (UE), may receive a message including an indication of a set of demodulation reference signal (DMRS) candidates for a data channel. The data channel may be a physical downlink shared channel (PDSCH) or a physical uplink shared channel (PUSCH) in some examples. The UE may determine a set of parameters associated with the set of DMRS candidates based on the received message. The set of parameters may correspond to a radio frequency spectrum subband or a radio frequency spectrum band associated with the data channel. The UE may estimate one or more characteristics of the data channel using the set of parameters associated with the set of DMRS candidates to perform wireless communication (e.g., PDSCH reception, PUSCH transmission).

Abstract: Methods, systems, and devices for wireless communications are described. The method may include a first network node receiving a configuration message for a report by the first network node of parameters for a temporal domain precoder. The configuration message may indicate a range of Doppler frequencies, a resolution associated with the range of Doppler frequencies, or a quantity of the parameters to be reported. The first network node may estimate a communications channel and select one or more bins within the range of Doppler frequencies based on the channel estimation. For each selected bin, the first network node may determine a corresponding discrete Fourier transform (DFT) vector and transmit a report indicating the corresponding DFT vector.

Abstract: A base station may select at least one of one or more 2D beams for at least one first SSB of a plurality of SSBs or one or more 3D beams for at least one second SSB of the plurality of SSBs. A UE may identify a beam type of at least one of one or more 2D beams for at least one first SSB of a plurality of SSBs or one or more 3D beams for at least one second SSB of the plurality of SSBs. The base station may transmit, to the UE, at least one of the at least one first SSB via the one or more 2D beams or the at least one second SSB via the one or more 3D beams.

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: 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.
