    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.

    摘要: Transmission of data from a portable communication device to a station via a radio frequency signal uses a protocol that has recurring frames, each having a plurality of transmission slots, different numbers of which can be used to transmit the data. When the portable communication device desires to send a data transmission, a first value is selected for either a power level for the radio frequency signal or the number of transmission slots to use. Then the first value is used to select a second value for the other one of the power level and the number of transmission slots. The first and second values are selected so that the data transmission at the selected power level using the selected number of transmission slots does not result in a specific absorption rate that is greater than a specific absorption rate limit.
