Title: ELECTRONIC DEVICE FOR COMMUNICATION DEVICE HAVING MULTIPLE ANTENNAS AND COMMUNICATION METHOD
Abstract:
Disclosed are an electronic device for a communication device having multiple antennas and a communication method. An electronic device for a first communication device having multiple antennas comprises: a memory, used for storing computer instructions; and a processing circuit, configured to execute the stored computer instructions to: determine, according to channel states of channels between multiple antennas of the first communication device and a second communication device, channel characteristics of a first channel from the first communication device to the second communication device within a range of angles; determine, according to the determined channel characteristics of the first channel within the range of angles, a first group of pilot signals to be used for the range of angles, wherein pilot signals in the first group of pilot signals are orthogonal to each other; and convert the first group of pilot signals into a second group of pilot signals to be transmitted via the multiple antennas of the first communication device.
