Abstract:
1. A method for wirelessly transmitting data and control information using a plurality of transmission layers, comprising: determining a number of bits in one or more user data codewords to be transmitted during a subframe; calculating, for each of M control signals to be transmitted during the subframe, a value (Q′), based at least in part, on: determining a number of control vector symbols onto which to map each of the M control signals based on a respective value Q′ calculated for that control signal; mapping each of the M control signals to the calculated number of control vector symbols for that control signal; and transmitting the user data vector symbols and the control vector symbols over a plurality of transmission layers during the subframe, wherein calculating the value Q′ for each of the M control signals comprises calculating a value Q′ wherein: P=└P N Q′ is a vector that includes the values Q′ associated with the M control signals, {circumflex over (Q)} O
