The invention discloses a method and a device in
user equipment and a
base station used for
wireless communication. The
user equipment monitors the first type of
wireless signals in a first time-frequency
resource pool and a second time-frequency
resource pool respectively; wherein the first time
resource pool and the second time resource
pool are located in a first sub-band and a second sub-bandrespectively; wherein the first time-frequency resource
pool comprises Q1 first time-frequency resource sub-pools; wherein the Q1 first time-frequency resource sub-pools are in one-to-one correspondence with Q1 second time-frequency resource sub-pools, and whether any first time-frequency resource sub-
pool in the Q1 first time-frequency resource sub-pools is occupied or not is used for determiningwhether the second time-frequency resource sub-pool comprises a corresponding second time-frequency resource sub-pool or not. According to the method and the device, the
user equipment is designed tomonitor the first type of
wireless signals on the plurality of sub-bands, and the monitoring mode is determined according to whether the resources are occupied or not, so that the
signal performanceperiodically sent on the unlicensed spectrum is improved.
