| description | Aspects of the present disclosure provide an apparatus and methods for recovering data from a control channel in wireless communications. An apparatus decodes a CRC appended codeword to obtain a decoded codeword, and computes a first syndrome of the decoded codeword utilizing a parity check matrix. If the first syndrome is non-zero, The apparatus determines a location S and a length K of an error pattern in bits of the decoded codeword, an index set based on the values of S and K. A linear system is formed based on the parity check matrix and the error pattern in accordance with the index set . The apparatus determines a solution of the linear system, wherein the solution includes an estimated error pattern. A recovered codeword can be determined by removing the estimated error pattern from the decoded codeword. |
