Embodiment Construction

[0037] The invention provides a closed-loop power control method of reverse supplementary channel. The present invention calculates the power offset G of R-SCH relative to R-PILOT by comprehensively counting the frame quality of R-FCH and R-SCH R-SCH The adjustment amount can realize the independent adjustment of the R-SCH power.

[0038] In order to make the principles, characteristics and advantages of the present invention more obvious, the present invention will be described in detail below in conjunction with the accompanying drawings. Schematic diagram of the implementation principle of the reverse supplementary channel closed-loop power control method according to the present invention, refer to Figure 4 .

[0039] The R-SCH closed-loop power control is applied to the "R-FCH closed-loop power control". "R-FCH closed-loop power control" completes the high-frequency and precise control of R-FCH and R-SCH, and "R-SCH closed-loop power control" completes the separate su...

Abstract

A closed loop power control method of reverse supplement channel includes accounting the frame quality combination condition of reverse supplement channel R-SCH and reverse primary channel R-FCH calculating the power bias's adjustment amount G<R-SCH> according to the said statistical result to adjust R-SCH power. Utilizing the said method of the present invention can ensure R-FCH error rate converges to the goal error rate, meanwhile achieve independence closed loop power control to R-SCH make R-SCH bit error converge to goal error rate commendably.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a closed-loop power control method of a reverse supplementary channel (ReverseSupplement Channel). Background technique [0002] Wireless communication will play an increasingly important role in future communication, and Code Division Multiple Access (CDMA) will become the main wireless access technology of the third generation mobile communication system. IS2000 is one of the standards of the third generation mobile communication system. [0003] In the reverse closed loop power control (RCLPC, Reverse Close Loop Power Control) function of the reverse traffic channel of the third generation mobile communication system applying the IS2000 standard, the power control of the reverse traffic channel is through the reverse pilot channel (R- PILOT) to complete. The base station controller (BSC) adjusts the R-PILOT power at a rate of 800 Hz using the reverse power control bit. ...
