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

TDSCDMA 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.
