摘要： A method and device for wireless communication in a UE and a base station is disclosed. The user equipment receives a first bit block, transmits or receives a first wireless signal on a first time-frequency resource set, and transmits a second wireless signal on a second time-frequency resource set. The user equipment determines to transmit the second wireless signal on the second time-frequency resource set. A second bit field in the first bit block is used to indicate the first time-frequency resource set. A first bit field in the first bit block is used to simultaneously indicate a first spatial parameter group for transmitting the first wireless signal and a second spatial parameter group for transmitting the second wireless signal or a first multiple access signature for generating the second wireless signal. The spatial parameter group information used for scheduling PDSCH or PUSCH is applied to the uplink grant-free transmission.
