Example Embodiment

[0081] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0082] In order to solve the existing process of traversing and searching potential transceiver beam combinations to determine the best transceiver beam, a large amount of system overhead needs to be occupied, system efficiency is reduced, and the ability to adapt to channel time changes is reduced, an embodiment of the present invention proposes A beam scanning method. The core idea of ​​this method is: when a transceiver link between th...

Abstract

The invention discloses a beam scanning method and related equipment used for solving the problem that a lot of system overhead needs to be occupied in the existing process of performing traversal search on a potential transceiving beam combination and determining an optimal transceiving beam, so that the system efficiency is reduced and the adaptability to channel time-varying is reduced. The method comprises the following steps: determining at least one transmitting beam by a first communication node according to an optimal receiving beam group between a receiver of the first communication node and a transmitter of a second communication node; and transmitting signals to the second communication node by the first communication node orderly according to the determined at least one transmitting beam through the transmitter, until an optimal transmitting beam is determined.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a beam scanning method and related equipment. Background technique [0002] In view of the important role of Multiple-Input Multiple-Output (MIMO) technology in improving peak rate and system spectrum utilization, Long Term Evolution (LTE) / LTE-Advanced (LTE-Advanced, LTE- A) and other wireless access technology standards are built on the basis of MIMO+Orthogonal Frequency Division Multiplexing (OFDM) technology. [0003] The performance gain of MIMO technology comes from the spatial freedom obtained by multi-antenna systems. Therefore, one of the most important evolution directions of MIMO technology in the standardization development process is the expansion of dimensions. In LTE Rel-8, up to 4 layers of MIMO transmission can be supported. Rel-9 focuses on enhancing the multi-user MIMO (Multi-User MIMO, MU-MIMO) technology, and the transmission mode (Transmissio...
