摘要:

在TD-SCDMA 系统中,上行不连续发射技术能够为TD-SCDMA 终端带来省电、降干扰等好处。现有标准中,默认上行DTX状态为开启,但又缺失相应的关闭机制,影响无线通信的性能和可靠性。通过对比3种开启-关闭方案的实施效果,研究并解决上行DTX状态不可控的问题,填补现有标准空白,满足通信系统的运营与管控需求。

Abstract:

Due to discontinuous transmission characteristics, uplink DTX could bring benefits such as terminal power-saving and interference reducing to TD-SCDMA system. During the existing standard, the default state of uplink DTX is on, without corresponding off mechanism, which may deteriorate the performance and reliability of communication system. In order to solve the uncontrollable problem of uplink DTX state, fill the blank of existing standards, and meet the operation demands of communication system, three kinds of on-off methods were introduced, and their implementation effects were discussed from six dimensions.
