SYSTEM AND METHOD FOR POWER CONTROL IN MIMO SYSTEMS
摘要
The return channel in a multiple-input and multiple-output (MIMO) communication system is used to provide signal information on an individual- channel basis. In one embodiment, in a controlled factory environment, this information may be used to incrementing up or down the variable gain amplifier and/or the power amplifier of a MIMO transmitter and/or receiver so as to generate a default signal power offset to be used during normal operation. Thereafter, such signal information may similarly be provided via the return channel and used to further adjust the transmit parameters to account for location-specific signal conditions.
