Abstract

The present invention provides a channel measurement method, a channel measuring device, a user device and a system, a wireless communication system comprising a channel measurement device and at least two user devices, the method comprising: the channel measuring device transmits an antenna domain training sequence to at least two user devices; The channel measuring apparatus transmits an antenna domain training sequence to the at least two user devices; The channel measuring apparatus receives the channel response measurement sequence transmitted by the at least two user devices, the channel response measurement sequence is the antenna domain training sequence after the channel is received by the at least two user devices; The channel measuring apparatus receives the channel response measurement sequence of at least two user devices in combination to obtain a downstream channel status information CIT. Using the technical solution provided by an embodiment of the present invention, the feedback overhead of the user device may be reduced.

Description

technical field [0001] The present invention relates to communication technology, in particular to a channel measurement method, a channel measurement device, user equipment and a system. Background technique [0002] Large-scale antennas are an important technology for the fifth-generation wireless communication system in the future. In wireless communication networks, large-scale antennas at the base station (Base Station, BS for short) can bring additional spatial multiplexing gain and diversity gain. For example, BS can be used Multiple antennas at the BS end can be used to implement interference cancellation between multiple users, and multiple antennas at the BS end can also be used to implement beamforming, thereby increasing the received signal energy at the User Equipment (UE) end. [0003] In the existing Frequency Division Duplex (FDD for short) wireless communication system, usually the method for obtaining the channel state information (Channel State Information...
