Abstract

The present application discloses a method and a device used in a wireless communication user equipment and a base station. The user equipment receives N groups of first configuration messages, receives Q pieces of indication information, and receives first control information. Wherein, the first control information is associated with first information, and the first information is one of the Q indication information, and the first information is used to obtain from the N groups of first configuration information Determine the first target configuration information; the first target configuration information is used to determine the first antenna port group set; the first reference antenna port group is an antenna port group in the first antenna port group set, for the Measurements of the first reference antenna port group are used to receive the first control information. The above method flexibly realizes the efficient management of the transmission of control information corresponding to multiple beam-based unlicensed spectrum access detections and the satisfaction of different requirements.

Description

technical field [0001] The present application relates to a wireless signal transmission method and device in a wireless communication system, especially a wireless signal transmission method and device in a wireless communication system supporting a cellular network. 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 avoid mult...
