SYSTEM AND METHOD FOR ALLOCATING TRANSMISSION RESOURCES

摘要

A method for wirelessly transmitting data and control information using a plurality of transmission layers includes determining a number of bits in one or more user data codewords to be transmitted during a subframe and calculating a number of control vector symbols to allocate to control information during the subframe. The number of control vector symbols is calculated based at least in part on the number of bits in the one or more user data codewords to be transmitted during the subframe and an estimate of the number of vector symbols onto which the one or more user data codewords will be mapped. The estimate of the number of vector symbols depends, at least in part, on the number of control vector symbols to be allocated to control information. The method also includes mapping one or more control codewords to the calculated number of control vector symbols and transmitting 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.
