摘要

FCC已经通过同步或电路交换操作为无牌个人通信服务(UPCS)分配了1920 MHz和1930 MHz之间的频段。UPCS频谱位于许可终端之间，使用UPCS频谱的专用室内无线系统和使用许可频谱的公共PCS系统之间的互操作性是可取的，并且受到FCC的鼓励。在之前的论文中，描述了基于FCC礼仪的个人接入通信服务-无许可B (PACS- ub)的端口信道分配过程，PACS是针对无许可操作修改的PACS版本，并给出了相应的上行链路和下行链路性能。结果表明，上行信噪比性能比下行信噪比差达8 dB。本文采用上行功率控制来提高系统性能。研究发现，通过上行功率控制，即使在高流量负载下，上行信噪比也可以提高5.5 ~ 7db。

Performance of PACS-UB for unlicensed operation with uplink power control

The FCC has allocated the band between 1920 MHz and 1930 MHz for Unlicensed Personal Communications Services (UPCS) using isochronous or circuit-switched operation. The UPCS spectrum lies between the licensed Terminal interoperability between private indoor wireless systems using the UPCS spectrum and public PCS systems using licensed spectrum is desirable and is encouraged by the FCC. In previous papers, a port channel assignment process based on the FCC etiquette for the Personal Access Communications Service-Unlicensed B (PACS-UB), a version of PACS modified for unlicensed operation, was described, and the corresponding uplink and downlink performance were presented. Results indicated that uplink SINR performance is inferior to that of the downlink by as much as 8 dB. In this paper, uplink power control is ’ employed to improve the performance. It is found that, with uplink power control, a 5.5 to 7 dB improvement in the uplink SINR can be achieved even for high traffic load.
