Method and device in UE and base station for radio signal transmission in wireless communication

A base station for wireless communication, comprising:

• a second transmitter, transmitting a first signaling, the first signaling being used to determine K time domain resource(s), K being a positive integer;
• and
• a second transceiver, executing a first radio signal in the K time domain resource(s);
• wherein the first signaling is a Downlink Control Information (DCI) signaling;
• the first radio signal carries a first bit block, a first time-domain-resource size and a target parameter are used to determine size of the first bit block, at least one of the K time domain resource(s) is used to determine the first time-domain-resource size;
• the first bit block comprises a Transport Block (TB), the size of the first bit block is a Transport Block Size (TBS);
• the target parameter is a first parameter or a second parameter, the first parameter is a positive integer, the second parameter is a positive integer, and the second parameter is less than the first parameter;
• whether the target parameter is the first parameter or the second parameter is related to the K, the K is a number of transmissions of the first bit block within a slot;
• when the K is equal to 1, the first radio signal comprises a transmission of the first bit block, and the target parameter is the first parameter;
• when the K is greater than 1, the first radio signal comprises K sub-signals, and the K sub-signals are respectively K transmissions of the first bit block, the target parameter is the second parameter, and the K is used to determine the second parameter;
• the executing is receiving, or, the executing is transmitting.
