WEIGHT FEEDBACK GRANULARITY SETTING METHOD, DEVICE AND SYSTEM

摘要

Provided in the embodiments of the present invention are a method, a device and a system for setting a weight feedback granularity, relating to communication technologies, which solve the problem that a beamforming transmitting end can not control a beamforming weight feedback granularity. The method comprises: receiving a null data packet announcement (NDPA) frame comprising a weight feedback granularity requirement value transmitted by the beamforming transmitting end; receiving a null data packet (NDP) frame transmitted by the beamforming transmitting end, and measuring the beamforming weight by using the weight feedback granularity requirement value as a granularity; and transmitting a very high throughput compressed beamforming (VCBF) frame to the beamforming transmitting end, wherein the very high throughput compressed beamforming (VCBF) frame comprises the beamforming weight using the weight feedback granularity requirement value as the granularity. The embodiments of the present inventions are suitable for setting a weight feedback granularity.
