Abstract: Methods, systems, and devices for wireless communication are described. Aspects of the disclosure describe narrow beam-based channel access that enables a device to communicate in a shared radio frequency spectrum band without performing channel access procedures. Specifically, aspects of the disclosure describe techniques for defining one or more directional beams as a narrow beam, where the relative narrowness of the beam may be determined in the context of interference (e.g., as opposed to being defined from a geometric perspective). For example, a particular beam may be determined to be a narrow beam, and therefore associated with communications in shared radio frequency spectrum bands without channel access procedures, based on one or more metrics and a number of spatial streams associated with the beam. A device may use such narrow beams for communications without channel access procedures in shared radio frequency spectrum bands.

Abstract: Methods, systems, and devices for wireless communications are described. A communication device, which may be otherwise known as user equipment (UE) may receive a downlink control information (DCI) on a physical downlink control channel (PDCCH). The DCI may include one or more of an indication of a set of transmission configuration indicator (TCI) states related to a physical downlink shared channel (PDSCH), one or more receive beams associated with the set of TCI states, or a physical downlink shared channel (PDSCH) scheme. The UE may decode the DCI and may determine a temporal period associated with the indication of the set of TCI states. The UE may receive, based on the temporal period, the PDSCH according to one or more of the set of TCI states, the one or more receive beams associated with the set of TCI states, the PDSCH scheme, or one or more default receive beams.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a transmitting (Tx) node may perform a channel measurement in a channel sensing contention slot based at least in part on a measurement time, wherein the measurement time is based at least in part on one or more of a sensing bandwidth or a beam switching time. The Tx may perform, to a receiving (Rx) node, a transmission based at least in part on a value of the channel measurement satisfying a threshold. Numerous other aspects are described.

Abstract: Wireless communication methods and devices for selective receiver-assisted channel sensing are provided. In some aspects, one or more receivers (e.g., UEs) can be selectively configured to perform receiver-assisted channel sensing (e.g., class A channel sensing) using at least one of trigger signaling and channel sensing configuration by a BS, UE capabilities, or operational mode. For example, a method for wireless communication performed by a user equipment (UE) includes: sensing a channel based on at least one of a receiver-assisted channel sensing trigger, or a UE capability; and transmitting, to a base station (BS) based on the sensing, channel sensing information.

Abstract: Method and apparatus for BSR and scheduling grant for target UE in sidelink relay. The apparatus receives a request for sidelink communication from a target UE. The apparatus receives a first BSR from the target UE via the sidelink communication. The apparatus transmits a second BSR to a network entity, the second BSR comprising information corresponding to at least one of the first BSR of the target UE or a sidelink BSR for the relay UE. The apparatus receives an allocation of resources for the sidelink communication with the target UE based on the second BSR. The apparatus communicates via the sidelink communication with the target UE using the allocation of resources.

Abstract: Mechanisms for directional channel occupancy monitoring for a frequency band among multiple networks are provided. In one aspect, a method of wireless communication includes monitoring, in a shared frequency band in a plurality of beam directions, for signals associated with one or more wireless networks different from the first wireless network. The monitoring includes: detecting, in the shared frequency band and in at least a first beam direction of the plurality of beam directions, a first signal associated with a second wireless network; and up-dating a channel occupancy list to indicate that at least a portion of the shared frequency band is occupied in at least the first beam direction. The method also includes transmitting, in the shared frequency band, a second signal in a second beam direction of the plurality of beam directions based on the channel occupancy list.

Abstract: In an aspect, a PDCCH and a PDSCH are transmitted by a BS to a UE, whereby the PDCCH includes a first DCI part and the PDSCH includes a second DCI part (e.g., a 2-part DCI). In an example a first grant associated with the second DCI part is offset relative to a slot position of the second DCI part, whereas a second grant associated with the second DCI part is offset relative to the slot position to which the first grant is offset. In another aspect, two or more grants are grouped together, with the respective group being mapped to a PUCCH.
