Abstract: A method of wireless communication performed by a user equipment (UE) may include: receiving, from a base station (BS), first downlink control information (DCI) scheduling an uplink (UL) communication; receiving, from the BS, a request to perform a clear channel assessment (CCA) associated with a first CCA timing configuration; performing, based on an indication to change to a second CCA timing configuration different from the first CCA timing configuration, the CCA based on the second CCA timing configuration; and transmitting, to the BS based on the CCA, the UL communication.

Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may support signaling for channel access using multi-beam sensing. In some cases, a user equipment (UE) may transmit a capability message indicating a capability of the UE to support per-beam channel access procedures for communicating in one or more shared radio frequency spectrum. In some cases, the UE may receive, from a network entity, a control message indicating a channel occupancy configuration that is associated with the per-beam channel access procedures. Additionally, the UE may perform a per-beam channel access procedure for each beam of a set of beams and may communicate via one or more beams from the set of beams based on the channel occupancy configuration and the per-beam channel access procedures being successful for at least a subset of beams of the set of beams.

Abstract: Methods, systems, and devices for wireless communications are described. In some aspects, a user equipment (UE) and a network entity may support a control mechanism according to which the UE determines whether an upgrade from a first channel access type to a second channel access type is available for an uplink transmission from the UE to the network entity. For example, the network entity may configure the UE with a set of channel access types and the UE may determine whether the second channel access type is available for the uplink transmission based on which channel access types are present in the set of channel access types. As such, the UE may upgrade from the first channel access type to the second channel access type if the second channel access type is present in the set of channel access types.

Abstract: Certain aspects of the present disclosure provide techniques for implicitly determining a receive beam for a UE to use for received signal strength indicator (RSSI) measurement. For example, the UE may perform RSSI measurement with a receive beam implicitly determined at the UE and report the RSSI to a network entity.
