摘要： The present disclosure discloses a method and a device for wireless communication in UE and base station. The user equipment determines a first time-frequency resource block by itself on a first sub-band and transmits a first wireless signal in the first time-frequency resource block on the first sub-band. Wherein, the first wireless signal carries a first bit block and a second bit block; the first time-frequency resource block comprises a first time-frequency resource sub-block, and whether the first time-frequency resource block comprises a second time-frequency resource sub-block is related to the number of bits included in the first bit block; the second bit block is used to determine the first time-frequency resource block; The above method allows the UE to dynamically select the size of the occupied uplink wireless resource according to the size of the actual data amount, while avoiding the resource waste and the extra transmission time delay.

摘要： The present disclosure provides a method and a device in a base station used for wireless communication. The base station transmits M1 first-type reference signals; receives M2 second-type radio signals in first time-domain resources, with any of the M2 second-type radio signals being associated with one of the M1 first-type reference signals; and transmits a first radio signal in the first time-domain resources. If an antenna port transmitting the first radio signal is associated with at least one of the M2 second-type radio signals, first-type channel monitoring is adopted targeting transmission of the first radio signal; otherwise, second-type channel monitoring is adopted targeting transmission of the first radio signal. The above method allows the base station to share a COT acquired by a UE in unlicensed spectrums so as to increase channel access efficiency, and at the same time avoids interference with other potential ongoing communications.
