Abstract: A UE may identify a first set of preserved resources of one or more sets of preserved resources. An aircraft-borne device may identify a first set of preserved resources of one or more sets of preserved resources. The first set of preserved resources may be associated with a time domain starting point, a time domain duration, and a frequency domain resource allocation. The UE may transmit, to an aircraft-borne device and the aircraft-borne device may, receive from the UE, over at least part of the first set of preserved resources, a synchronization signal and a first payload message. The first payload message may include a first emergency message and may be transmitted and received via one of a first PUSCH, a first PSSCH, or a PSCCH. The aircraft-borne device may forward, to a base station or another aircraft-borne device, at least the first emergency message.

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: 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: 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: Methods, systems, and devices for wireless communication are described. A wireless device may transmit feedback, such as hybrid automatic repeat request (HARQ) feedback for groups of code blocks rather than for an entire transport block or individual code blocks. The wireless device may transmit an acknowledgement (ACK) or negative-acknowledgement (NACK) to provide feedback for each code block group of a set of code block groups. An ACK may indicate that code blocks in a code block group were successfully decoded, and a NACK may indicate that at least one code block in a code block group was not successfully decoded. Wireless devices may support several techniques for grouping code blocks for feedback reporting to allow for efficient retransmissions and limited overhead. Different grouping schemes may be employed depending on system constraints, device capability, link conditions, or the like.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive quasi co-location (QCL) information associated with an energy harvesting beam.
