Abstract

The embodiments of the present invention provide an optimal beam determining method, a user terminal, and a network side device. The method includes the following steps that: a user terminal selects the optimal transmitting beam of a network side device and the optimal receiving beam of the user terminal; if the user terminal has a transmitting beam that is in receiving and transmitting reciprocity with the optimal receiving beam of the user terminal, the user terminal adopts the transmitting beam that is in receiving and transmitting reciprocity with the optimal receiving beam of the user terminal as the optimal transmitting beam of the user terminal or determines the optimal transmitting beam of the user terminal from a beam set to which the transmitting beam in receiving and transmitting reciprocity with the optimal receiving beam of the user terminal belongs. With the optimal beam determining method, the user terminal, and the network side device provided by the embodiments of thepresent invention adopted, the number of the times of beam training can be decreased.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method for determining an optimal beam, a user terminal and a network side device. Background technique [0002] In the current communication system, both the user terminal and the network-side device support multi-beams, but in actual data communication, the user terminal and the network-side device often use the optimal beam for communication. For example, the user terminal uses the optimal sending beam to perform uplink communication with the optimal receiving beam corresponding to the network-side device, and the user terminal uses the optimal receiving beam to perform downlink communication with the optimal sending beam corresponding to the network-side device. Among them, the above-mentioned optimal beam is 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,...
