Description

technical field [0001] Embodiments of the present invention relate to the technical field of wireless communication, and in particular, to a method and device for calculating gains of multiple receiving links / transmitting links. Background technique [0002] In a multi-antenna beamforming system, there are multiple transmit links and multiple receive links. When the system is running, the link gain value of each receive link needs to be obtained, and based on the link gain value of each receive link Calculate the received total wideband power (Received Total Wideband Power, hereinafter referred to as RTWP), and the obtained RTWP can be used to judge the interference situation of the entire network, so that the network side can judge the access according to the interference situation; it is also necessary to obtain the gain of each transmission link, Closed-loop power control is performed according to the transmission chain. [0003] In the prior art, when obtaining the link...
