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