摘要： Information transmission in a multiple-input multiple-output (“MIMO”) wireless communication system is provided. In one embodiment, a method for transmitting information in a MIMO wireless communication system, comprising updating channel quality information (“CQI”) values of a plurality of wireless devices, wherein updating said CQI values consider the effects of interference from transmissions to those wireless devices associated with a pre-assigned companion codeword set; pairing said plurality of wireless devices using at least said CQI values, a precoding matrix index (“PMI”) value and said pre-assigned companion codeword set, wherein said pre-assigned companion codeword set, pre-assigned companion codewords associated with said pre-assigned companion codeword set and said PMI value are updated for each of said plurality of wireless devices; precoding the information for each of said plurality of wireless devices using said PMI value; and transmitting said precoded information to each of said plurality of wireless devices.
