摘要： A control channel encoder includes a determiner configured to determine a current value of K for encoding control signals of a length M, wherein K is a function of a code rate for a data channel. A table generator is configured to, if K is greater than a predetermined threshold, generate a repeated matrix from a fixed block encoding matrix by variably repeating rows from said fixed block encoding matrix. A puncturer is configured to, if K is less than the predetermined threshold, puncture the fixed block encoding matrix to reduce a size of the fixed block encoding matrix. A block encoder is configured to utilize said repeated matrix, to encode M input control bits as K encoded control bits, by generating an encoded payload from said repeated matrix.

摘要： A method includes receiving reference signals in a mobile communication terminal, which is designed to receive data-carrying signals that are transmitted from a base station using one of multiple predefined Modulation and Coding Schemes (MCSs). One or more pre-calculated mappings between Signal-to-Noise Ratio (SNR) and error rate for one or more of the MCSs are held in the communication terminal. The pre-calculated mappings are adjusted according to one or more transmission parameters of the data-carrying signals. Measures indicative of respective actual spectral efficiencies that are achievable by the MCSs are estimated based on the adjusted mappings using the received reference signals. A preferred MCS is selected based on the estimated measures, and feedback that is indicative of the preferred MCS is sent to the base station.
