Patent ID: 8526383

Claim:
A method for wirelessly transmitting data using a plurality of transmission layers, comprising: estimating a number of user data vector symbols to be allocated to one or more user data codewords during the subframe; determining a number of bits in the one or more user data codewords; calculating a nominal number of control vector symbols to allocate to control information based, at least in part, on the estimated number of user data vector symbols and the determined number of bits in the one or more user data codewords; determining an offset value based, at least in part, on a number of layers over which the wireless terminal will be transmitting during the subframe; calculating a final number of control vector symbols by multiplying the nominal number of control vector symbols and the offset value; mapping one or more control codewords to the final number of control vector symbols, wherein the control codewords comprise encoded control information; and transmitting, from a wireless terminal, vector symbols carrying the one or more user data codewords and the one or more control codewords over the plurality of transmission layers during the subframe.
