Abstract
In a method of transmitting control channel symbols in an OFDM communication system downlink in each sub-frame, the OFDM communication system including one or more transmit antennae, for each transmit antenna, each of the OFDM symbols of a control channel which are to be transmitted over the air is mapped to each of the corresponding non-punctured logical resource elements of one virtual control resource block VCRB. For each transmit antenna, the logical resource elements in each virtual control resource block VCRBare mapped to physical resource elements in each of the first L OFDM symbols so that the physical resource elements are uniformly spaced over the entire transmission bandwidth. For each transmit antenna, the physical resource elements are transmitted to user equipment.
