A METHOD FOR MAPPING A PHYSICAL DOWNLINK CONTROL FORMAT INDICATOR CHANNEL TO A PHYSICAL RESOURCE

摘要

A method for mapping a physical downlink control format indicator channel to a physical resource includes the steps that 16 modulated data y(0),...,y(15) of a downlink control signaling indicator channel in a LTE system are divided into 4 groups in order and mapped by groups, which allows the indicator channel of downlink control format to be mapped to continuous 4 resource units recombined by resources which are divided among all system physical resources except the pilot frequency according to the continuous 4 resource units. By defining group mapping rules, the method may obtain a maximum gain of frequency selectivity.;COPYRIGHT KIPO & WIPO 2010
