Abstract

The invention discloses a power control method embedded into a D2D cellular network and based on a time domain half-duplex relay, and belongs to the technical field of wireless communications. The method relates to a base station B using a point-to-multipoint topological structure cellular network for transmitting, a cellular network receiving terminal C, a D2D transmitting terminal R used as a cellular communication relay and a D2D receiving terminal E; the D2D transmitting terminal is used as a cellular communication relay between the base station B and the receiving terminal C, cellular communication and D2D communication are subjected to combined power control, the full-duplex wireless relay technology is used for achieving orthogonal communication channel frequency spectrum multiplex of the cellular communication and the D2D communication, the minimum data throughout requirement of the cellular communication is met, meanwhile, the throughout of the D2D communication is maximized, hence, the overall performance of the system and the individual performance of users can be considered at the same time, and good balance can be achieved between the system layer and the user layer.

Description

Technical field [0001] The invention relates to a power control method for full-duplex relay, and is particularly suitable for a power control method based on full-duplex relay in a D2D-embedded cellular network used in the field of wireless communication technology. Background technique [0002] With the continuous increase of broadband mobile multimedia services, improving the user capacity, coverage, and service quality of cellular networks has become an important issue to be solved in wireless mobile communications. D2D communication technology is a brand-new wireless communication technology that the mobile communication standardization organization 3GPP-LTE has paid attention to and studied in recent years. D2D communication refers to: on the premise of not affecting the data transmission of other cellular users and D2D users, user terminals in close geographic locations can establish a direct communication link for data transmission without transiting through a base statio...
