Title:
METHOD AND DEVICE FOR CHANNEL CHARACTERISTICS TEST AND COMMUNICATION IN MIMO SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/009580
Kind Code:
A1
Abstract:
The invention provides a method for channel characteristics test and communication in MIMO system. A transmitter allocates transmitting power of pilot signals corresponding to different transmitting directions based on channel statistical characteristics between transmitting antennas and receiving antennas, and a receiver determines channel state information according to the pilot signals, such that the precision of the channel characteristics test is optimized and the system performance is improved. Also a part of pilot signals which contribute little to the channel characteristics test can be replaced with data signals, such that the system throughput can yet be increased.
