DATA TRANSMISSION METHOD AND TERMINAL FOR D2D COMMUNICATION

摘要

A data transmission method and terminal for D2D communication. The method may comprise: a first D2D terminal acquires, according to a bit number occupied by a time advance indication parameter ITAI and a time advance indication parameter NTA, the ITAI and D2D data sending advance parameter TA'; the first D2D terminal sends the ITAI to a second D2D terminal via a physical sidelink control channel (PSCCH), so that the second D2D terminal acquires the TA' according to the received ITAI; and the first D2D terminal sends, according to the TA' and a basic time unit Ts, D2D data to the second D2D terminal, so that the second D2D terminal receives the D2D data sent by the first D2D terminal according to the acquired TA' and the Ts.
