Abstract:
1. In an orthogonal frequency division multiplexing (OFDM) wireless communication system, a method of mapping physical control format indicator channel (PCFICH) symbols to resource elements in one of a plurality of OFDM symbols associated with a downlink slot, the method comprising: determining the position, K mapping each of the PCFICH symbols in groups of four to a corresponding set of four resource elements, in the OFDM symbol as a function of K wherein a first group of four PCFICH symbols is mapped to a first set of four resource elements in the OFDM symbol, where the first resource element of the first set of four resource elements is at the position K wherein a second group of four PCFICH symbols is mapped to a second set of four resource elements in the OFDM symbol, where the first resource element of the second set of four resource elements is at a position defined by K wherein K
