Beam recognition method and system and network node

Abstract

The invention discloses a beam recognition method, a beam recognition system and a network node. The method beam recognition comprises the steps that: a first network node sends one or a group of beam recognition auxiliary information to a second network node, wherein the beam recognition auxiliary information corresponds to one or a group of high-frequency sites and is used for indicating beam information required for accessing the high-frequency site to the second network node; and the second network node obtains the one or a group of beam recognition auxiliary information, and recognizes an optimal beam of the high-frequency site according to the obtained beam recognition auxiliary information. By adopting the beam recognition method, the beam recognition system and the network node, since the second network node obtains the beam recognition auxiliary information required in the beam recognition process, the detection range in the access process is reduced; in addition, when compared with the method of accessing the high-frequency site through blind test, the complexity of optimal beam recognition is reduced, the time delay in the optimal beam recognition process is shortened, and further the access rate to the high-frequency site is increased.

Description

technical field [0001] The present invention relates to a long term evolution advanced system (LTE-Advanced, Long term evolution advanced system), in particular to a high-frequency communication-based beam identification method, system and network node. Background technique [0002] With the continuous development of radio technology, a large number of various radio services have emerged, and the spectrum resources on which radio services rely are limited. Facing the continuous increase in people's demand for bandwidth, traditional commercial communications mainly use 300MHz~3GHz Spectrum resources are extremely tense, which cannot meet the needs of future wireless communications. [0003] In the future wireless communication, carrier frequencies higher than those used in the fourth generation (4G) communication system will be used for communication, such as 28GHz, 45GHz, etc. This high-frequency channel has a large free propagation loss, The shortcomings of being easily ab...

Problems solved by technology

For terminals without any prior information, this will greatly increase the time delay of downlink synchronization and identification of the optimal beam, which will seriously affect the access speed of the terminal to the high-frequency site; The complexity of identification reduces the accuracy of identification, and even causes the terminal to fail to identify the optimal beam

[0007] The above-mentioned technical problems do not provide a feasible solution for beam identification based on high-frequency communication in the prior art
