Abstract

The present invention provides a base station resource configuration method for user D2D scheduling configuration and D2D data transmission and corresponding user equipment. The base station sends the D2D scheduling configuration and / or the resource configuration mode of D2D data transmission to the user equipment. The network side predefines the D2D scheduling configuration and / or the frequency hopping mode of D2D data transmission within a subframe and between subframes. The user equipment obtains the D2D scheduling configuration and / or the time-domain transmission mode of the D2D data according to the D2D scheduling configuration and / or the resource configuration mode of the D2D data transmission sent by the base station. The user equipment obtains the D2D scheduling configuration and / or the transmission mode of the D2D data in the time domain according to the D2D scheduling configuration and / or the frequency hopping mode of the D2D data transmission within a subframe and between subframes predefined by the network side.

Description

technical field [0001] The invention relates to the technical field of wireless communication. More specifically, the present invention relates to user equipment and methods thereof. Background technique [0002] The modern wireless mobile communication system presents two notable features. One is high broadband speed. For example, the bandwidth of the fourth-generation wireless mobile communication system can reach 100MHz, and the downlink rate can reach as high as 1Gbps; , online navigation and other emerging businesses. These two characteristics put forward higher requirements for wireless mobile communication technology, mainly including: ultra-high-speed wireless transmission, inter-regional interference suppression, reliable signal transmission during movement, distributed / centralized signal processing, etc. In the future enhanced fourth-generation (4G) and fifth-generation (5G) wireless mobile communication systems, in order to meet the above-mentioned development n...
