摘要： A method for wirelessly transmitting data using a plurality of transmission layers includes estimating a number of vector symbols (124) to be allocated to transmission of user data codewords (122) during a subframe and determining a number of bits in a plurality of user data codewords (122) to be transmitted during the subframe. The method also includes calculating a number of control vector symbols (124) to allocate to control information based at least in part on the estimated number of vector symbols ( 124) and the determined number of bits. Additionally, the method includes mapping control codewords ( 122) to the calculated number of control vector symbols (124) and transmitting vector symbols (124) carrying the user data codewords (122) and the control codewords ( 120) over the plurality of transmission layers during the subframe.

摘要： A precoder for an effective channel linking a wireless receiver to a wireless transmitter includes a precoder report and a precoder update report, the effective channel including a propagation channel, transmit filters and receive filters. A structured frequency-selectivity of the effective channel is determined, the structured frequency-selectivity being induced by one or more long term and/or persistent parameters of the effective channel. The precoder update report is generated based on the structured frequency-selectivity. The precoder update report includes frequency-dependent phase compensation which accounts for the structured frequency-selectivity. The precoder report is generated for the effective channel based on channel state information determined for the effective channel. The precoder report and the precoder update report are transmitted to the wireless transmitter. The transmitter determines a transmission operation based on the precoder report and the precoder update report, and transmits data to the wireless receiver in accordance with the transmission operation.
