Abstract

The present application discloses a method and a device used in a wireless communication user equipment and a base station. The user equipment monitors the first type of wireless signal in the first time-frequency resource pool and the second time-frequency resource pool respectively; the first time resource pool and the second time resource pool are respectively located in the first sub-frequency band and the second time-frequency resource pool sub-band; the first time-frequency resource pool includes Q1 first time-frequency resource subpools, and the Q1 first time-frequency resource subpools are in one-to-one correspondence with Q1 second time-frequency resource subpools, and the Q1 Whether any first time-frequency resource subpool in the first time-frequency resource subpools is occupied is used to determine whether the second time-frequency resource pool includes a corresponding second time-frequency resource subpool. The present application designs the user equipment to monitor the first type of wireless signal on multiple sub-bands, and determines the monitoring method according to whether the resource is occupied, thereby improving the performance of the signal periodically sent on the unlicensed spectrum.

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 ...
