摘要
本文对空分复用在TD-SCDMA以及LTE中的应用条件进行了研究。为了能够充分利用设备硬件资源,增加系统吞吐量,利用室外天线实现的空间隔离以及室内多通道设备在不同楼层间的隔离实现空分复用,在重用业务信道资源的条件下,能够大幅度提高频谱利用率及系统吞吐量。由于控制信道资源不能够重用,因此空分复用所能够支持的用户数受到控制信道资源的限制。
This paper discusses conditions of applying SDM in TD-SCDMA and LTE. To take full advantages of HW resources and increase throughput of the system, we use space isolation of outdoor antennas and isolation of indoor multi-channel devices in different layers to implement SDM. In the condition of reusing traffic channels, the proposed SDM can increase frequency usage and system throughput. Because control channels cannot be reused, subscriber capability supported by the SDM is limited by the numbers of control channels.
