Abstract

The invention discloses a method and a device in user equipment and a base station used for wireless communication. The user equipment firstly receives a first signaling, then sends a first wireless signal, and then sends a second signaling. The time domain resource occupied by the first signaling is used for determining the time domain resource occupied by the second signaling, the first wirelesssignal is used for determining the time domain resource occupied by the second signaling, and the first signaling and the second signaling are respectively transmitted on a cellular link and a side link. According to the invention, the time domain resources occupied by the first wireless signal and the second signaling are associated, so that the adjacent base stations monitor the control signaling on the side link in D2D transmission, the inter-cell interference coordination is further realized, and the system performance and the transmission efficiency are improved.

Description

[0001] This application is a divisional application of the following original application: [0002] --The filing date of the original application: 2017.05.04 [0003] --Application number of the original application: 201710307301.2 [0004] --The name of the invention of the original application: a user equipment used in wireless communication, a method and a device in a base station technical field [0005] 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 [0006] 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 ...
