Fremgangsmåde og apparat til transmission af styreinformation i et trådløst kommunikationssystem

摘要

A method for receiving control information through a preamble comprising Layer 1 (L1) part II signaling information in a communication system, the method comprising the steps of:
acquiring information on a number of bits of Layer 1 (L1) part II signaling information from a received frame;
calculating a number of LDPC blocks into which the L1 part II signaling information is divided;
calculating a number of input information bits of each LDPC block when there are a plurality of LDPC blocks, such that the multiple LDPC blocks are equal in the number of input information bits, and calculating a number of puncturing bits among parity bits of each LDPC block; and
decoding one or more received LDPC blocks based on the information acquired and calculated in the preceding steps.
