The Resource Scheduling And Power Control Algorithm On TD-HSUPA System

3G wireless communication system can provide higher wireless transmission capacity, better quality of service experience, and more sorts of services, making communication more rapid, diverse and universal. TD-SCDMA system is an access standard of 3G mobile communication system with independent intellectual property rights owned by our country. To support high-speed data services, TD-SCDMA has introduced two enhanced standards, HSDPA and HSUPA, which can respectively provide 2.2Mbps and 2.8Mbps peak rate on radio interface on uplink and downlink with a single 1.6MHz frequency bandwidth. HSDPA and HSUPA have now completed the agreements on standardization work and all manufacturers have invested in the product design and testing.This paper will give the design and simulation analyzation on both scheduling and power control/grant algorithms for HSUPA base station-side. First, for the scheduling algorithms, the designation will start from the perspective of getting close to the specification and use the actual system parameters to obtain the calculation and derivation of the formulas. For different algorithms, the scheduling features will embodied by different scheduling factors. In this paper, the TD-HSUPA implementation of MaxSINR, PF, and RR, which are all common algorithms, will be given separately. And all the scheduling factors will be grouped by their physical meanings and be classified into levels corresponding to the throughput. Through simulation, the realization of algorithm characteristics will be analyzed.Second, for the power control and grant, the designation will combine the features of TD-HSUPA uplink and the common resource configuration, i.e. TDM. The ordinary inner loop power control and outer loop power control will be demonstrated. And two different algorithms for power grant will be given with different advantages on system throughput, UE throughput and interference level. The performance of the two algorithms under different parameters will be put into the simulation with the TDM resource configuration. It proves that there is conflict between throughput and interference level and that means the sector throughput will be lost if the interference level is under control and the performance of users on cell edge may be under promotion.At last, the QoS depending scheduling algorithms and interference coordination method in power granting algorithms may be the next stage of this paper.
