ABSTRACT:
In a transmission node, a portion of the control information is separated into M (M is an integer) parts of control information blocks having N (N is an integer) bit length. A control information parity having (8−N) bit length is added to control information block i. The control information block is encoded to M parts of control information having 8 bit length according to a predetermined control information bit array. The control information parity and the control information bit array are set such that Hamming distance of each of the control information code is d, and Hamming distance of the control information 10B code is D (d and D are integers). In a receiving node, the control information code is separated into the control information block and the control information parity. Parity check is performed. When an error is detected, error processing is performed.
