1. A method in a User Equipment (UE) for wireless communication, comprising: monitoring a first signaling; andwhen the first signaling is detected, monitoring a second signaling, or receiving a first radio signal;
wherein the first signaling comprises a first field; the first signaling carries first sub-information besides the first field, or the first signaling carries second sub-information besides the first field; the first field in the first signaling is used for determining whether the first sub-information or the second sub-information is carried in the first signaling; the first sub-information is used for determining a first time-frequency resource pool, time-frequency resources occupied by the second signaling belong to the first time-frequency resource pool, and the second sub-information is used for determining time-frequency resources occupied by the first radio signal;
and the first signaling, the second signaling and the first radio signal are all transmitted via an air interface; and
wherein:
a first bit block is used for generating the first signaling after being processed through channel coding, a second bit block is used for generating the second signaling after being processed through channel coding, the first bit block comprises a positive integer number of bits, the second bit block comprises a positive integer number of bits, and the number of bits comprised in the first bit block is smaller than the number of bits comprised in the second bit block; or,
a first identification is used for the detection of the first signaling, a second identification is used for the detection of the second signaling, and the first identification is different from the second identification.
