SYSTEM AND METHOD FOR ALLOCATING TRANSMISSION RESOURCES BASED ON A TRANSMISSION RANK

摘要

A method for wirelessly transmitting data with a transmitter using a plurality of transmission, layers includes estimating a number of data vector symbols (124) to be allocated to one or more user data codewords (122) during the subframe arid determining a number of bits in the one or more user data codewords (122), The method also includes calculating a nominal number of control vector symbols (124) to allocate to control information based., at least in part, on the estimated number of data vector symbols (124) and the determined number of bits in the one or more user data codewords (122). Additionally, the method includes determining an offset value based, at least in part, on a number of layers over which a transmitter (100) will be transmitting during the subframe and calculating a final number of control vector symbols (124) by multiplying the nominal number of control vector symbols (124) and the offset value. The method also includes mapping one or more control codewords (120) to the final number of control vector symbols (124) and transmitting the user data vector symbols and the control vector symbols over the plurality of transmission layers during the subframe.
