Firstly, half frame is used in type 2 frame format(TDD). that means downlink and uplink data are transmited in the same frequency. The TDD system uses switching point to separate downlink and uplink signal. If the tdd system don‘t use half frame, the round trip time will be 10ms or more. Which means large system delay. In order to solve this problem, half frame is introduced.
