Abstract

The present application discloses a method and a device used in a wireless communication user equipment and a base station. The user equipment first receives the first signaling, then sends the first wireless signal, and then sends the second signaling. The time domain resource occupied by the first signaling is used to determine the time domain resource occupied by the second signaling, and the first wireless signal is used to determine the time domain resource occupied by the second signaling For time domain resources, the first signaling and the second signaling are transmitted on the cellular link and the secondary link respectively. In this application, the design establishes a connection between the first wireless signal and the time-domain resources occupied by the second signaling, so that the adjacent base stations can monitor the control signaling on the secondary link in the D2D transmission, and then realize inter-cell interference coordination. , improve system performance and transmission efficiency.

Description

technical field [0001] The present application relates to a transmission method and device in wireless communication, and in particular to a method and device used for communication between an air terminal and a ground terminal. Background technique [0002] In 3GPP (3rd Generation Partner Project, third-generation partnership project) Release 12, D2D (Device to Device, inter-device) communication was established and discussed. The essential feature of D2D is to allow UE (User Equipment, user equipment) data transfer between. In the current Mode 1 transmission mode in D2D transmission, the base station sends the resources occupied by the PSSCH on the sidelink (Sidelink) to the sending terminal in D2D transmission through DCI (Downlink Control Information, downlink control information), and then the sending terminal sends the PSSCH The occupied resources are sent to the receiving terminal in D2D transmission through SCI (Sidelink Control Information, secondary link control i...
