Methods, systems, and devices for wireless communications are described. A user equipment (UE) may rate match an uplink transmission around a set of resources reserved by a base station. The base station may indicate a set of reserved resources which overlaps an uplink resource allocation to the UE. The base station may transmit an indicator of the reserved resources, and the UE may identify a location of a clear channel assessment (CCA) gap in a symbol period relative to the reserved resources. By rate matching around the reserved resources and one or more CCA gaps, the UE may transmit uplink information despite the allocated uplink resources colliding with the reserved resources.

Provided in implementations of the present disclosure are a method and device for determining a length of feedback information, and a communication apparatus. The method includes that a first node determines a number of feedback information bits according to information of a number of Hybrid Automatic Retransmission Request (HARQ) processes and information of at least one transmission resource.

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment or a base station may determine that a condition for entering a reduced monitoring state is satisfied, wherein the reduced monitoring state uses at least one of: a diminished radio frequency chain configuration, a diminished channel monitoring configuration, a restriction on receiving or transmitting a shared channel or a control channel, or a combination thereof; and communicate using the reduced monitoring state. Numerous other aspects are provided.

Methods, systems, and devices for wireless communications are described. A base station may identify a listen-before-talk (LBT) procedure to use for transmitting a downlink signal to a user equipment (UE) on a shared radio frequency spectrum band. The LBT procedure may be a group LBT procedure associated with a first set of contention window durations or an individual listen-before talk procedure associated with a second set of contention window durations. The base station may determine a contention window duration corresponding to the identified LBT procedure, perform the identified LBT procedure using the determined contention window duration, and transmit the downlink signal to the UE based on the performed LBT procedure.
