Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first base station may sense a channel based at least in part on a sensing time period. The first base station may receive, from a user equipment (UE), a dynamic frequency selection (DFS) signal on the channel during the sensing time period. The first base station may determine to refrain from communicating on one or more of a beam associated with the DFS-assisted signal or the channel on which the DFS-assisted signal is received for a defined duration of time, based at least in part on an indication of the one or more of the beam or the channel being added to a non-occupancy list. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, a first radio resource control (RRC) configuration message that is associated with a first subband and that indicates a first set of transmission configuration indicator (TCI) states for use on the first subband. The UE may further receive, from the base station, a second RRC configuration message that is associated with a second subband included in the wideband channel and that indicates a second set of TCI states for use on the second subband. As an alternative, the UE may receive, from the base station, an RRC configuration message that includes at least a first list of first TCI states associated with a first subband and a second list of second TCI states associated with a second subband. Numerous other aspects are described.

Abstract: Certain aspects of the present disclosure provide techniques for wireless communication by a base station (BS). In some examples, the techniques include receiving, from a user equipment (UE), one or more indications of one or more actual beam strengths as measured at the UE at one or more time periods for one or more transmit beams of the BS. In some examples, the techniques include receiving, from the UE, assistance information regarding the one or more actual beam strengths.

Abstract: Certain aspects of the present disclosure provide techniques for predicting a strength of a transmission beam in a communication system. In one example, the disclosure describes a user equipment (UE) receiving a quality metric from a base station (BS), the quality metric indicating one or more tolerance levels for predicted beam strength as compared to actual beam strength at the UE. In some examples, the UE may transmit, to the BS, one or more indications of actual beam strength as measured at the UE at one or more time periods for one or more transmit beams of the BS.

Abstract: Certain aspects of the present disclosure provide techniques for determining and using channel ratio metrics for beamformed communication. A method that may be performed by a user equipment (UE) includes selecting a first beam of a plurality of beams for determining one or more channel ratio metrics, determining the one or more channel ratio metrics for the first beam, wherein determining the one or more channel ratio metrics is based, at least in part, on an angular separation between the first beam and one or more neighboring beams of the plurality of beams, and transmitting signaling via the first beam based on the one or more channel ratio metrics

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitter node may determine a set of desired transmit beams to use for transmissions during a channel occupancy time (COT), wherein each transmit beam in the set of desired transmit beams is associated with an energy detection threshold (EDT). The transmitter node may configure a sensing beam associated with a directional listen-before-talk (LBT) procedure, wherein the sensing beam is associated with an EDT that is at least as strict as a strictest EDT associated with the set of desired transmit beams. The transmitter node may transmit using the set of desired transmit beams during the COT, wherein the COT is initiated based at least in part on an indication that the directional LBT procedure succeeded using the sensing beam. Numerous other aspects are described.
