摘要
省电技术是移动通信终端设计的一项关键技术。研究了非连续接收技术及其在TD-SCDMA系统中的应用。分析了3GPP标准中的非连续接收方案,指出了方案中的缺陷,并提出了改进方案。仿真结果表明,与3GPP标准中的非连续接收方案相比,该方案不仅改善了连接模式下终端的耗电量问题,而且能够根据实时状况对非连续接收的周期进行动态配置,有效降低了耗电量,延长了待机时间。
Powering saving is one of the key technologies in mobile terminal design. In this paper, the discontinuous reception technology and its application in TD-SCDMA system are described. The discontinuous reception program in the 3GPP standard specification is analyzed, its flaws are pointed out and an improved program is also proposed. Relatively, the improved program does not only improve the power consumption in connected mode, but also dynamically configure the cycle of discontinuous reception according to the real-time status. Simulating results show that, the improved program can effectively reduce the power consumption and extend the standby time.
