Method and device for beam pairing between devices

Abstract

The embodiment of the invention provides a method and device for pairing wave beams among devices, wherein the method for pairing the wave beams among devices comprises the steps: the devices send first wave beam pairing requests to a network coordinating device, wherein the first wave beam pairing requests are used for obtaining the number of an optimal wave beam zone of opposite-end devices of the devices in the network coordinating device, the opposite-end devices are used for communicating with the device, and the coordinate system of the devices and the coordinate system of the network coordinating device are aligned; according to the number of the optimal wave beam zone of the opposite-end device in the network coordinating device, sent by the network coordinating device, the devices determine the minimum wave beam zone set of the opposite-end devices in the optimal wave beam zone of the network coordinating device in the wave beam zone set of the devices; and in each wave beam zone in the minimum wave beam zone set, the devices send a training sequence to the opposite-end devices or receive the training sequence sent by the opposite-end devices. According to the embodiment of the invention, the devices can be avoided sending or receiving training sequences in unnecessary wave beam zones, thus delay in pairing of the wave beams among the devices is reduced, and the power consumption of the devices is decreased.

Description

technical field

[0001] Embodiments of the present invention relate to communication technologies, and in particular to a method and device for pairing beams between devices. Background technique

[0002] Under the existing centralized network architecture, two devices need to perform beam pairing before wireless communication to obtain their respective optimal transmit beams and optimal receive beams, so that the sending end sends data to the receiving end on the optimal transmitting beam, and at the same time The receiving end receives the data from the sending end at the optimal receiving beam.

[0003] At present, beam pairing usually adopts a sequential scanning method, as follows: In a symmetrical antenna system, it is assumed that device A has EA receiving beams and EA transmitting beams, and device B has EB receiving beams and EB transmitting beams. Device A sends EB repeated training sequences on each transmit beam, and device A sends a total of EA×EB training seque...
