Embodiment Construction

[0023] When the operator decides to use the proportional fair scheduling algorithm as the sector MAC-hs scheduling algorithm for scheduling, the embodiments of the present invention can provide multiple scheduling modes of the proportional fair scheduling algorithm, such as a mode that focuses on scheduling fairness and takes into account scheduling Modes of fairness and cell throughput, modes focusing on cell throughput, etc., as shown in Figure 1, there are N types of proportional fairness scheduling algorithms in the figure, and the fairness of mode 1 is closest to the scheduling algorithm of maximum carrier-to-interference ratio, which is Among all modes, the fairness is the worst, and the sector throughput is the largest. The fairness of mode N is the closest to the fair service time, and the fairness is the best among all parameters, and the sector throughput is the smallest.

[0024] This embodiment provides a new weight calculation method. By setting different schedulin...

Abstract

The proportion equity dispatch algorithm (PEDA) possesses multiple dispatch modes of providing multi choices between throughput of sector and service fairness for operation manager. The method includes following steps: (1) determining configuration parameter for each mode of PEDA; (2) saving the said configuration parameters in base station; (3) using far end maintenance platform or near end maintenance platform sends the selected dispatch mode in PEDA to base station; (4) after receiving dispatch mode of modified PEDA, base station makes appointed mode effect instantly or in time.

Description

technical field [0001] The invention relates to a WCDMA HSDPA (high-speed downlink packet access) system, in particular to a proportional fair scheduling algorithm of a MAC-hs scheduler in the WCDMA HSDPA. Background technique [0002] In the MAC-hs scheduler of the WCDMA HSDPA system, the scheduling algorithms include: fair service time, maximum carrier-to-interference ratio and proportional fair scheduling algorithm, where: [0003] In the fair service time (Round Robin, RR) algorithm, the service time (scheduling times) obtained by each UE is almost exactly the same, and this scheduling algorithm is the fairest, but the throughput rate is the lowest. [0004] In the maximum carrier-to-interference ratio scheduling algorithm (MAX-C / I), the MAC-hs scheduler of the base station provides services for UEs with the best signal quality first, and only serves UEs with poorer signal quality if there are remaining resources. Therefore, the sector can get the maximum throughput, bu...
