Реферат: Certain aspects of the present disclosure provide techniques for per transmission configuration channel sensing. A method for wireless communication by a user equipment (UE) generally includes monitoring a plurality of dummy physical downlink control channel (PDCCH) transmissions from at least one base station (BS). The dummy PDCCH transmissions use a different transmission configuration. The UE sends acknowledgment feedback for the plurality of dummy PDCCH transmission. The ACK feedback for the dummy PDCCH transmissions may be multiplexed with ACK feedback to the at least one BS for physical downlink shared channel (PDSCH) transmissions. A UE may receive a configuration reserving one or more bits in a UE codebook for providing the ACK feedback. Each reserved bit may be for control resource sets associated with a transmission configuration. The UE monitors PDDCH transmissions using different transmission configurations and uses the reserved bits to transmit ACK feedback for the PDCCH transmissions.
