Abstract: Wireless communications systems and methods related to narrow beam-based channel access for communications in a wireless communication network operating over an unlicensed spectrum are provided. A first wireless communication device receives, from a second wireless communication device, one or more signals associated with a beam parameter. The first wireless communication device determines, at each of a plurality of locations, a signal measurement for at least one received signal of the one or more received signals. The first wireless communication device determines, based at least in part on an p-th percentile signal measurement and a q-th percentile signal measurement of the signal measurements at the plurality of locations, whether the second wireless communication device satisfies an interference condition.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a receiving user equipment (UE) may receive, from a transmitting UE, a first communication associated with a channel occupancy time (COT) of the transmitting UE and at least one of a cast type or a channel type. The UE may transmit a second communication in the COT of the transmitting UE based at least in part on the cast type or the channel type of the first communication. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first user equipment (UE) may transmit, to a set of second UEs, information indicating a duplexing pattern of the first UE, wherein the duplexing pattern indicates one or more reception intervals of the first UE and one or more transmission intervals of the first UE. The UE may communicate in accordance with the duplexing pattern. Numerous other aspects are described.

Abstract: A method of wireless communication performed by a first wireless communication device includes: receiving, in first sidelink (SL) resources of a shared frequency band comprising a first interlace of resource blocks (RBs) within one or more first RB-sets, a first SL communication in a first slot and a second SL communication in a second slot; and transmitting, in second SL resources of the shared frequency band comprising the one or more first RB-sets and a second interlace of RBs, a first SL feedback communication for the first SL communication and a second SL feedback communication for the second SL communication, wherein the transmitting the first SL feedback communication and the second SL feedback communication is based on a mapping of the first SL communication and the second SL communication to the second interlace of RBs in the one or more first RB-sets.

Abstract: Aspects relate to the amount of shared bandwidth to be used for channel occupancy time (COT) sharing. An initiator device may use a clear channel assessment procedure to gain access to wireless communication resources for a COT that will be shared between the initiator device and a responder device. In some examples, the responder device may determine the shared bandwidth based on information that is implicit in a transmission from the initiator device. For example, the responder device may determine the shared bandwidth based at least in part on a bandwidth of a transmission from the initiator device.

Abstract: A method for wireless communication includes a first wireless communication device receiving, from a second wireless communication device, one or more signals for each of a plurality of candidate sensing beams and a transmission beam. The method also includes determining, for each of the plurality of candidate sensing beams based on at least one of the one or more signals for the respective candidate sensing beam, a first signal measurement. The method also includes determining, based on at least one of the one or more signals for the transmission beam, a second signal measurement with respect to a direction of the transmission beam, and determining, for each of the plurality of candidate sensing beams based on the respective first signal measurement and the second signal measurement, beam coverage information with respect to the transmission beam direction.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) performs a first channel access procedure for accessing a channel occupancy time (COT) within the sidelink channel. The UE transmits a second-stage sidelink control information (SCI) message (SCI-2) including COT sharing information (COT-SI) for sharing the COT with other devices, and transmits a first sidelink message within a first portion of the COT. The UE identifies a second sidelink message that is expected to be received within a second portion of the COT, and performs a second channel access procedure for accessing the COT after identifying the second sidelink message based on the second sidelink message being expected within a set of resources reserved for the second sidelink message. Subsequently, the UE transmits a third sidelink message within a third portion of the COT based on a completion of the second channel access procedure.

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, an indication associated with performing listen-before-talk relative to a channel occupancy time (COT). Accordingly, the UE may transmit, to the base station, an uplink communication, where the uplink communication is transmitted using a listen-before-talk (LBT) procedure based at least in part on the indication. For example, the LBT procedure may be selected from a category 1 (Cat1) LBT procedure, a category 2 (Cat2) LBT procedure, or a category 3 (Cat3) LBT procedure based at least in part on the indication (e.g., included in a radio resource control message). The LBT procedure may be further based at least in part on downlink control information from the base station. Numerous other aspects are described.
