在TD-SCDMA建网初期,A频段主要使用9频点方案配置组网,满足了小网络低载频配置的应用需求.然而,随着TD-SCDMA网络不断发展扩大,单站载频资源配置逐渐由S222增加至S333,频点资源有限的情况下,9频点配置方案很难在基于容量配置的TD-SCDMA网络中平衡各业务的性能.本文提出TD-SCDMA载波带宽压缩方案,通过压缩频点间隔,使TD-SCDMA网络使用的A频段增加2个中心频点,即11中心频点方案,解决因频点资源有限造成的网络性能提升空间小的问题,降低TD-SCDMA网络R4语音业务及H业务的干扰水平,同时增加网络承载容量.

At the beginning of the TD-SCDMA constructing, band A is mainly using 9 frequencypoints to configure the TRXs, which would easily match various applications bearded on small network. However, with the continuous development of the TD-SCDMA network, the frequency allocation in single station would gradually increase such as S222 to S333, 9 frequencies reused solution in whole NW is hard to balance the performance among business which under the shortage of frequencies.In this paper, TD-SCDMA carrier bandwidth compression scheme is issued. With the frequency interval compressing, the TD-SCDMA network adds 2 extra center-frequencies in A band, consequently, overall 11 center frequencies solution could increase the capacity and solve the shortage of resource. In addition,the interference created from R4(voice) and H(data)would be suppressed since the more flexible utilization in frequencies.
