Link recovery method and device and equipment

Abstract

The embodiment of the invention provides a link recovery method and device and equipment. The method comprises the steps that if quality of a link between first equipment and second equipment does notsatisfy a preset condition, the first equipment detects whether the link is recovered or not within timing duration of a first timer, thereby obtaining a detection result, wherein the timing durationof the first timer is the interruption duration of link interruption resulting from user movement; and the first communication equipment determines whether to perform link recovery operation or not according to the detection result, wherein the link recovery operation comprises at least one piece of operation of beam tracking operation, beam refinement operation and redo-beamforming operation. According to the embodiment of the invention, the condition of blindly recovering the link through the link recover operation under a scene that the quality of the link is reduced transiently due to human blockage and then is recovered can be avoided, namely, comprehensive judgment can be carried out through combination of the practical condition that the quality of the link is reduced, and the linkrecovery accuracy is greatly improved.

Description

Technical field [0001] The embodiments of the present invention relate to communication technologies, and in particular, to a method, device, and equipment for link recovery. Background technique [0002] 802.11ad is a subsystem in the wireless local area network system. It works in the high frequency band of 60GHz (57GHz-66GHz). It is mainly used to realize wireless high-definition audio and video signal transmission in homes and enterprises. It has high capacity and high capacity in multimedia applications. Features such as speed, low latency, and low power consumption. [0003] In the existing 802.11ad standard, a beam link maintenance timer (link maintenance timer) is used to maintain the trained link. The value of the link maintenance timer is negotiated by both ends of the link (that is, the sender and the receiver) Decided. The link maintenance timer starts when the link beam training is completed and gradually decreases. When the non-self data transmission period is encou...
