Problems solved by technology

[0004] The time for the terminals at both ends of the transceiver to complete beamforming training needs to be determined according to the number of antennas at both ends of the transceiver. The more antennas, the longer it takes to complete beamforming training. Beam training is required between the base station and the terminal. The beamforming also needs to be performed between the terminals. In the case of shaping training, more channel resources need to be occupied, and in the case of a large number of terminals, the spectrum utilization rate of the system will be reduced

Abstract

The application relates to the technical field of wireless communication, and provides a communication method between a terminal and the terminal, network side equipment and the terminal. The method comprises the following steps: the network side equipment distributes time frequency resource for transmitting uplink information and sidechain information for the terminal; the terminal transmits theuplink information for performing uplink beam training to the network side equipment at the same moment in the time frequency resource range on the time frequency resource, and transmits the sidechaininformation for performing sidechain beam training to another terminal. Through the scheme provided by the embodiment of the invention, the terminal can perform the beamforming training of the sidechain without additionally using the new time frequency resource based on the traditional uplink and downlink beamforming training procedure.

Description

technical field [0001] The present application relates to the technical field of wireless communication, and in particular to a method for communicating between terminals, a network side device and a terminal. Background technique [0002] With the development of wireless communication technology and the popularization of smart terminals, the number of terminals in the wireless cellular network is in the stage of explosive growth, and the services supported by the wireless communication system have also developed from the initial voice and SMS to support wireless high-speed data communication. At the same time, the number of wireless connections around the world is experiencing continuous rapid growth, and various new types of wireless services are also emerging in large numbers, such as the Internet of Things, virtual reality (Virtual Reality, VR), etc. The system puts forward higher requirements. [0003] Communication between terminals includes D2D (Device to Device, dev...
