Abstract
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.
