Abstract

The invention discloses a transmission method of D2D (device-to-device) communication links, a base station and a terminal. According to the transmission method, a HARQ processing mechanism is introduced to the transmission process of the data packets of the D2D communication links, so that the reliability of link transmission can be improved. The transmission method of D2D communication links provided by the invention includes the following steps that: the base station configures a hybrid automatic repeat request (HARQ) feedback resource pool for a first terminal and a second terminal which are connected into the base station, and D2D communication links are built between the first terminal and the second terminal; and the base station broadcasts the HARQ feedback resource pool to the first terminal and the first terminal.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular to a transmission method of a device-to-device (English full name: Device-to-Device, English abbreviation: D2D) communication link, a base station, and a terminal. Background technique [0002] D2D communication refers to a technology that realizes direct communication between short-distance user equipment without the aid of a third party. With the popularity of smart terminals, the number of smart terminals in the network is in the stage of explosive growth. At this time, the industry begins to focus on the development of D2D technology. The reason is that D2D technology under the cellular architecture can not only help operators share heavy network load, Offloading cellular services, supplementing the existing cellular network architecture and bringing new profit revenue models, and based on the natural advantages of short-distance communication, D2D technolog...
