Abstract

The invention discloses user equipment for wireless communication, and a method and device in a base station. The user equipment receives a first signal at first, and then transmits a first wireless signal, and finally transmits a second signal. A time domain resource occupied by the first signal is used for determining a time domain resource occupied by the second signal. The first wireless signal is used for determining the time domain resource occupied by the second signal, and the first and second signals are respectively transmitted on a cellular link and a secondary link. Through the design of building a correlation between the time domain resources occupied by the first wireless signal and the second signal, the user equipment achieves a purpose that the adjacent base stations monitors a control signal on the secondary link in the D2D transmission, thereby achieving the inter-cell interference coordination, and improving the system performances and transmission efficiency.

Description

Technical field [0001] This application relates to a transmission method and device in wireless communication, and more particularly 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) Release 12, D2D (Device to 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 to the sending terminal in D2D transmission through DCI (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) and PSSCH to realize data communication. [0003] In the 3GPP discussions on 5G, the SI (Study Item) for Enhanced Support for ...
