Abstract: Disclosed are techniques for radio frequency (RF) sensing. In an aspect, a network entity (e.g., base station or road-side unit) may perform RF sensing in a first mode for sensing a horizontal angle using horizontal multiple input, multiple output (MIMO) radar with vertical beamforming, in which a two-dimensional MIMO antenna array is configured into a plurality of vertical columns, each column comprising a plurality of antenna elements configured to transmit as a phased array, each column transmitting a different orthogonal signal from the other columns. The network entity may perform RF sensing in a second mode for sensing a vertical angle using vertical MIMO radar with horizontal beamforming, in which the MIMO antenna array is configured into a plurality of horizontal rows, each row comprising a plurality of antenna elements configured to transmit as a phased array, each row transmitting a different orthogonal signal from the other rows.

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: A method of wireless communication, by a user equipment (UE), includes receiving, from a network device, a trigger command initiating a hash-based random access procedure. The trigger command includes a target hash value and one or more rules for selecting preambles. The method also includes selecting, based on the trigger command, one or more random access channel (RACH) occasions (RO) for potential preamble transmission. The method further includes calculating at least one hash value in response to the trigger command based on computational resources of the UE. The method also includes transmitting a preamble on the at least one selected RO based on the at least one hash value and the target hash value.

Abstract: Methods, systems, and devices for wireless communications are described. A network entity (e.g., a base station or reader) may transmit an initial access trigger message (e.g., modulating a continuous wave transmission using amplitude shift keying (ASK)), and the trigger message may include an indication of a type of passive user equipment (PUE) or a PUE use case (e.g., high priority/latency-critical PUEs or low priority/latency non-critical PUEs). A receiving PUE may harvest energy from the initial access trigger message for transmitting an initial access response message including an identifier for the receiving PUE. The receiving PUE may transmit the initial access response message (e.g., on one or more initial access resources) using the harvested energy if the trigger message indicates the PUE's type of PUE or PUE use case. In some examples, the receiving PUE may ignore triggers for different types of PUEs or PUE use cases.

Abstract: Disclosed are techniques for radio frequency (RF) sensing by a base station operating in a time division duplex (TDD) mode and having a first antenna panel and a second antenna panel. The base station performs RF sensing and DL communication in a first sensing and DL communication mode in which the first antenna panel transmits DL symbols and the second antenna panel receives, as RF sensing signals, reflections of the DL symbols transmitted by the first antenna panel. The base station also performs RF sensing and DL communication in a second sensing and DL communication mode in which the second antenna panel transmits DL symbols and the first antenna panel receives, as RF sensing signals, reflections of the DL symbols transmitted by the second antenna panel. In some aspects, a characteristic of the channel is determined based on transmissions in both the first and second sensing and DL communications modes.

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 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.
