Method, device and system for processing beam searching

Abstract

The embodiment of the invention provides a method, a device and a system for processing beam searching. The method comprises the steps of abstracting the beam searching to be a problem for seeking a global optimum solution through two searching stages of rough searching and fine searching, so that the coordinative searching between both communication parts is realized; the good searching property is provided; the efficiency of the beam searching is obviously improved; and the time and the power consumption needed by the beam searching are reduced.

Description

technical field [0001] Embodiments of the present invention relate to the field of wireless communication technologies, and in particular, to a beam search processing method, device, and system. Background technique [0002] With the development of multimedia applications, the demand for transmission rate and signal bandwidth of wireless communication applications is increasing day by day, and the demand for high-speed data transmission such as online video streaming services is gradually becoming prominent. The corresponding Wireless Personal Area Networks (WPAN) also requires data The transmission rate and signal bandwidth put forward higher requirements. At present, the 100M transmission rate that mobile networks and Wireless Local Area Networks (WLAN) strive to meet the application requirements; on the other hand, many existing wireless communication services such as broadband mobile communication, satellite navigation communication, local area network And metropolitan ...

Problems solved by technology

[0004] In the process of realizing the present invention, the inventors found that there are at least the following problems in the prior art: the existing beam search algorithm is mainly based on ergodic search, its search complexity is high, and the search time required for beam alignment is unbearable, which seriously limits The performance of beamforming in 60GHz applications mainly has the following shortcomings: blindness: during the beam search process, the communication parties do not have a clear search target, and the optimal solution can only be found after an exhaustive search; redundancy : There is great redundancy in the search process, and the search of many beam numbers has no practical beneficial effect on the discovery of the optimal solution; lack of coordination: there is a lack of necessary coordination between the receiving end and the sending end, and the search efficiency is bound to be greatly affected
