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

Embodiment Construction
[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0027] Because 60GHz wireless communication can realize the transmission rate of Gbps or even several Gbps, it has become a new subject of research in the field of wireless communication. Improving the efficiency of the beam alignment process can not only save a lot of transmit power, but also provide the necessary prerequisite for the realization...

A wave beam search processing method, device and system. The method abstracts the wave beam search as a problem of searching for a globally optimal solution by way of two stages, namely rough search and fine search, realizing coordination search of two communication parties, with a good search performance, which can significantly improve the efficiency of the wave beam search, and shorten the time and power consumption required by the wave beam search.
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 ...
