基于最小信道能量的多点-多用户协作切换

在分布式蜂窝网络中,多个RRU与多个UE参与的双端协作为实现更加灵活高效的协作切换提供了可能。文章提出了一种支持多点-多用户协作切换的方法,以用户的最低SNR需求作为QoS参数指标求出最小信道能量值,以该值作为协作切换的门限值。通过对当前RRU/UE协作组合与RRU/UE协作组合空间备份内信道质量的动态监测,实现自适应的协作软、硬切换。该方法能有效的降低切换率,提高切换成功率。

Multi-point to Multi-user Cooperative Handoff Based on The Minimum Channel Energy

In distributed cellular network , Double-ended collaboration involved several RRU and UE make the more flexible and efficient cooperative handoff to be possible. In this paper roposed a method to support multi-point to multi-user cooperative handoff, Use the user"s minimum requirements SNR as QoS parameter index to calculated the minimum channel energy value and use the value as the threshold value of cooperative handoff. Dynamic monitoring channel quality of the being used RRU/UE cooperative unit and the alternate RRU/UE cooperative unit, It achieve adaptive cooperative soft handoff and cooperative hard handoff. The new strategy can reduce the handoff times and improve the probability of successful handoff.
