Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting node may perform a directional listen-before-talk (LBT) using a sensing beam. The transmitting node may start a channel occupancy time (COT) after the directional LBT based at least in part on one of a COT claiming signal or a time stamp. The transmitting node may perform, to a receiving node, one or more transmissions during the COT using one or more transmit beams that are included in the sensing beam. Numerous other aspects are described.

Abstract: Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums for beam formed partial sensing by a user equipment (UE). An example method generally includes performing partial sensing by monitoring for sidelink transmissions from one or more other UEs using one or more different beams during one or more different portions of a sensing window; and selecting resources, within a resource selection window, for future sidelink communications based on results of the partial sensing.

Abstract: Aspects described herein relate to resource block allocation for time domain single-carrier waveform processing in new radio (NR). Specifically, in an aspect, a guard band may be allocated for a single-carrier waveform in a time or frequency domain. In another aspect, a resource block may be allocated for a time domain single-carrier waveform.

Abstract: Aspects presented herein may improve the power control of a communication device in an ultra wide bandwidth beamforming systems. Aspects presented herein may enable the communication device to adjust one or more parameter of a power control loop based the sub-band used within a BWP or based on the channel used within a channelized frequency band. In one aspect, a UE receives at least one power control parameter for transmitting one of a first PUSCH, a first PUCCH, or a first SRS to a base station. The UE transmits the one of the first PUSCH, the first PUCCH, or the first SRS at a first power based on a first sub-band within a BWP.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment may determine to switch from a first beamforming mode to a second beamforming mode, wherein one of the first beamforming mode and the second beamforming mode is a digital beamforming mode, and wherein the other of the first beamforming mode and the second beamforming mode is an at least partially analog beamforming mode; and perform a communication using the second beamforming mode. Numerous other aspects are provided.

Abstract: Aspects relate to beam management reports that enable selection of best antenna panel and beam combinations for uplink transmissions from a user equipment (UE) when one or more antenna panels of the UE are subject to a maximum permissible exposure (MPE) limit. The UE receives a reference signal at a plurality of antenna panels, wherein the reference signal is received in different beams on each of the plurality of antenna panels. The UE determines N beams providing highest measured strengths of the reference signal on at least one of the plurality of antenna panels, wherein the MPE limit is to be applied to the at least one of the plurality of antenna panels for uplink transmissions. The UE transmits a beam management report including reduced highest measured strengths of the reference signal in the N beams to account for the MPE limit.

Abstract: A user equipment (UE) and base station may be configured to implementing trigger-based joint TX-RX sensing for channel access. In some aspects, the UE may monitor, via a receiver, for one or more transmissions from a first base station, detect, during the monitoring, interference associated with a pre-grant communication, the pre-grant communication associated with a future communication between a second base station a second user equipment, and transmit, via a transmitter, a reservation communication to the second base station in response to the pre-grant communication. In some aspects, the UE may receive the one or more communications from the first base station, without interference from the second base station, based on transmitting the reservation communication.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a base station may transmit, and a user equipment (UE) may receive, initial timing advance information in a msg2 communication of a four-step random access channel procedure based at least in part on a subcarrier spacing in a cell associated with the base station. The UE may transmit, and the base station may receive, a msg3 communication with an initial timing advance that is based at least in part on the initial timing advance information. The base station may transmit, and the UE may receive, updated timing advance information resolving a timing advance wrap-around between the UE and the base station based at least in part on the base station detecting the msg3 communication. Numerous other aspects are provided.

Abstract: Aspects are provided that allow a base station to use visual information of interfering UEs for optimizing shared channel access and beam and interference management and tracking. The base station may obtain visual information of a UE. The base station may then access a shared channel to communicate with the UE based on the visual information. After accessing the shared channel, the base station may communicate with the UE over the shared channel using one or more beams based on the visual information. Efficient channel access and communication in mmW environments may thereby be achieved.
