Impact of Key Techniques on Packet Traffics in LCR TDD Systems
LCR TDD系统中关键技术对分组数据业务的影响

Key techniques and the advanced RRM (Radio Resource Management) algorithms in LCR TDD systems are researched in this paper. An scheduling algorithm based on rate-prediction is proposed. In order to compare these technique functions, different scheduling strategies combined with SA (Smart Antenna) or JD (Joint Detection), which improve the throughput of packet traffics are simulated in dynamic system layer simulation. As some curves are obtained, new RRM algorithm with both SA and JD can not only balance the opportunity of all users, but also keep the throughput of users in cross slots at a high level.
