Abstract

An embodiment of the invention discloses a detection method, a detection system and detection equipment which are applied to the technical field of communication. The detection method includes that detection for fields containing power-saving flags is omitted after a beamformee receives an NDP (null data packet) frame, so that the beamformee cannot enter a sleep state, and computed channel feedback information can be fed to a beamformer within the duration of a transmit opportunity. The detection method, the detection system and the detection equipment have the advantages that the beamformer and the beamformee do not need to carry out operation for the fields containing the power-saving flags in the NDP frame, in other words, the purpose of normal feedback can be achieved without cooperation of the beamformer and the beamformee, and accordingly a detection process is simplified.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a detection method, system and equipment. Background technique [0002] 802.11 is a wireless local area network standard formulated by the IEEE group, which uses the medium access control (Medium access control, MAC) layer to establish addressing and channel access control mechanisms for multiple sites in the same network, making communication between multiple sites become possible. [0003] The supplementary protocol IEEE802.11ac of this standard also develops the high-throughput sounding mechanism (VHT Sounding Protocol) in the wireless LAN, that is, the channel detection mechanism between the beamforming initiator (Beamformer) and the beamforming receiving device (Beamformee) , through this mechanism, the beamforming initiating device can better know the channel conditions between the beamforming receiving device and the beamforming receiving device, so as to achieve t...
