TRANSMISSION METHODS FOR CCFI/PCFICH IN WIRELESS COMMUNICATION SYSTEM Russian patent published in 2012 - IPC H04B7/26 

FIELD: information technology.

SUBSTANCE: disclosed is a method of transmitting a control channel format indicator (CCFI), also known as PCFICH (Physical Control Format Indicator Channel), in case where the length of a coded CCFI is not an integer multiple of three, including mapping a plurality of two-bit CCFI into a codebook with each component codeword having three bits; generating a sequence of codewords selected from the codebook by repeating the selected component codeword for a predetermined number of times; generating a codeword by concatenating the sequence of the selected component codewords with the original CCFI bits; and transmitting the codeword carrying information on CCFI. The method further includes a step for generating a permutation of each of the four codewords by assigning K repetitions of the three-bit component codeword to the number of K resource units respectively and mapping the remaining K bits of each of the four codewords separately to the number of K resource units.

EFFECT: high efficiency of the transmission diversity scheme.
