Abstract

Embodiments of the present invention provide a method for determining an optimal beam, a user terminal, and a network-side device. The method includes: the user terminal selects an optimal sending beam of the network-side device and an optimal receiving beam of the user terminal; if the user The terminal has a transmit beam that is reciprocal with the optimal receive beam of the user terminal, then the user terminal uses the transmit beam that is mutually reciprocal with the optimal receive beam of the user terminal as the optimal transmit beam of the user terminal beam, or determine the optimal transmission beam of the user terminal from the beam combination to which the transmission beam reciprocal with the optimal reception beam of the user terminal belongs. The embodiment of the present invention can reduce the number of beam training times.

Description

technical field [0001] The present invention relates to the field of communication technologies, and in particular, to an optimal beam determination method, a user terminal and a network side device. Background technique [0002] In a current communication system, both the user terminal and the network-side device support multiple beams, but during actual data communication, the user terminal and the network-side device often use optimal beams for communication. For example, the user terminal uses the optimal transmit beam to perform uplink communication with the optimal receive beam corresponding to the network side equipment, and the user terminal uses the optimal receive beam to perform downlink communication with the optimal transmit beam corresponding to the network side equipment. Among them, the above optimal beams are mainly determined by training each beam. For example, if the network side equipment has 360 transmit beams and the user terminal has 260 receive beams,...
