Summary:PROBLEM TO BE SOLVED: To provide a method and apparatus for channel estimation in a system employing differing transmission protocols as broadcast/multicast and unicast protocols.SOLUTION: The number of pilot tones used for a broadcast transmission is greater than the number of pilot tones used for a unicast transmission. The channel estimation may be significantly degraded when a symbol from a broadcast transmission slot is adjacent to a symbol from a unicast transmission slot. Therefore, it is determined whether a first time slot of one transmission protocol (multicast slot) is adjacent to a second time slot of another transmission protocol (unicast slot). The pilot power and/or the number of the pilot sub-carriers are/is increased for the edge symbol of the multicast slot for purposes of channel estimation using the edge symbol.
