The first communication apparatus adjusts the AMPDU aggregation during subsequent communication with the second communication apparatus by creating a Block-ACK frame with a reserved field, which has a value indicating a change to the AMPDU aggregation, and then transmitting the Block-ACK frame to the second communication apparatus.

A BS may determine a configuration of one or more beams for a UE to monitor for receiving a downlink control channel from the BS, wherein the configuration is based, at least in part, on a monitoring window since the subframe in which the downlink control channel (e.g., PDCCH), indicates an initial UL, DL, or SL use data transmission for the UE. The BS may transmit, to the UE, an indication of the configuration. A UE may perform corresponding operations and may monitor one or more beams based on the received configuration.

A wireless device such as a user equipment (UE) may determine a set of scheduled synchronization signal transmission times. A first subset of the set of scheduled synchronization signal transmission times may be allocated for dynamic measurement. The wireless device may select at least one candidate beam from a set of candidate beams for a dynamic measurement during one of the transmission times in the first subset. The at least one candidate beam may be selected based at least in part on a fairness metric, a signal strength metric, a timing metric, or a combination thereof. The wireless device may perform a measure procedure on the selected at least one candidate beam and may transmit a measurement report based at least in part on the measure procedure to another wireless device (e.g., a base station).

Abstract: Quasi-colocation (QCL) for listen before talk (LBT) procedures is disclosed. A base station having a plurality of antennas may identify one or more groups of QCL antennas. Various aspects provide for different rules defining the QCL relationship, such as base on interference experienced by the antennas, a physical or logical connection of the antennas and LBT coupling, or synchronization. QCL may further be determined across multiple shared channels, such as based on frequency separation or frequency band of the channels. Once grouped as QCL, the base station performs the LBT procedure to reserve access to the one or more shared communication channels. If the LBT is successful, the base station may then transmit a channel reservation preamble on the shared communication channels in response.
