Embodiment Construction

[0060] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0061] The present invention proposes a joint optimization method of a D2D communication mode and a transmission beam, which effectively solves the problem of D2D communication management in a multi-antenna multi-user MIMO wireless network. There is a base station and multiple user pairs in the network, and both the user and the base station are equipped with multiple antennas. One of each pair is used for transmitting and one for receiving. Information transmission from transmission to reception is either directly transmitted through the D2D transmission mode, or relayed by the base station through the base station relay transmission mode. At the same time, setting the D2D transmission mode and the base station re...

Abstract

The present invention relates to a method for joint optimization of transmission mode and transmission beam in D2D communication. In uplink transmission, base station relay transmission mode and D2D transmission mode share transmission beam; in downlink transmission, base station relay transmission mode and D2D transmission mode Using different transmit beams, the present invention considers a multi-user MIMO network. Both the base station and the user are equipped with multiple antennas, and the D2D transmission mode and the base station relay transmission mode have the same priority, and the D2D transmission mode and the base station transmission mode can be simultaneously implemented. Relay transmission mode switching, energy allocation, MIMO transmission, and interference management.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a joint optimization method of a transmission mode and a transmission beam in D2D communication. Background technique [0002] As a very promising technology in wireless networks, D2D communication has attracted much attention recently. In mobile communication networks, D2D communication can effectively improve network throughput, energy utilization, spectrum utilization and communication reliability. [0003] Although the existing technologies consider the mode conversion, power allocation and beamforming of D2D communication, most of the work considers relatively simple scenarios, such as only considering single-antenna networks and strictly limiting the number of user pairs; a few studies consider D2D transmission mode conversion, power allocation and beamforming problems in multi-antenna MIMO networks, but these studies are still in the preliminary stage, for ex...
