Title: METHOD FOR HYBRID PRECODING AND COMMUNICATION DEVICE
Abstract:
Embodiments of the present disclosure relate to a method for hybrid precoding and a communication device. For example, at a communication device in a wireless communication system, a plurality of signals associated with a pilot are received from a plurality of antennas of a further communication device over a wireless channel. Then, angle-domain characteristics of the wireless channel are determined based on the plurality of signals, and spatial correlation characteristics of the wireless channel is determined based on the determined angle-domain characteristics. Moreover, since complete channel state information is no longer needed in determining the spatial correlation characteristics of the wireless channel, the pilot-related signals shorten in the time are sent from the transmitter end to the receiver end. There is further disclosed a communication device capable of implementing the above method.
