Abstract

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.

Description

technical field [0001] The present application relates to a transmission method and device in a wireless communication system, in particular to a transmission method and device supporting periodic transmission of wireless signals on an unlicensed spectrum (Unlicensed Spectrum). Background technique [0002] In the traditional 3GPP (3rd Generation Partner Project, 3rd Generation Partnership Project) LTE (Long-term Evolution, long-term evolution) system, data transmission can only occur on the licensed spectrum. However, with the rapid increase of traffic, especially In some urban areas, licensed spectrum may be difficult to meet traffic demands. The communication on the unlicensed spectrum in Release 13 and Release 14 is introduced by the cellular system and used for downlink and uplink data transmission. In order to ensure compatibility with other access technologies on unlicensed spectrum, LBT (Listen Before Talk) technology is adopted by LAA (Licensed Assisted Access) to ...
