A METHOD AND DEVICE FOR PILOT MAPPING IN MULTIPLEXING MODE OF UNICAST AND BROADCAST/MULTICAST SERVICES

摘要

A method and device for pilot mapping in multiplexing mode of unicast and broadcast/multicast services are disclosed and include following steps: generate different pilot symbol for unicast services and broadcast/multicast services respectively. In a frame, the broadcast/multicast pilot symbols transmitted on each antenna are arranged in the same slot on time field and border on each other. Sub-carriers transmitted on an antenna are a sub-carrier apart, and pilot symbol interleaving is arranged on time field. Broadcast/multicast pilot symbols are mapped onto several antennas along with unicast pilot symbols.
