Problems solved by technology

Since the data sent by the UE in the HSUPA system is adjusted by the uplink power control, the two sending powers may not be the same. Therefore, evaluating the channel quality of the current UE based on the SNR of the last transmission will lead to inaccurate evaluation and thus affect the scheduling performance.

Embodiment Construction

[0058] In order to make the purpose, technical means and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0059] The basic idea of ​​the present invention is to prioritize resource scheduling for UEs whose synchronization, power control, and beamforming performance cannot be guaranteed, and UEs whose service QoS requirements are not met, so as to avoid UEs that may be caused by existing scheduling methods. Synchronization loss, beamforming performance degradation, and service QoS requirements cannot be met.

[0060] figure 1 It is an overall flowchart of the resource scheduling method of HSUPA in the present invention. Such as figure 1 As shown, the method flow includes:

[0061] Step 101, preset user categories include retransmission UE, long-term unscheduled UE, GBR not guaranteed UE, and normal scheduling UE, and correspond to the four types of scheduling prioriti...

Abstract

The invention discloses a resource scheduling method for HSUPA, which comprises the following steps: presetting user categories comprising UE for retransmission, UE not scheduled for a long time, UE of which the GBR is not ensured, and UE normally scheduled, which orderly correspond to four scheduling priorities sorted from high to low; in the resource scheduling, determining the user category of each UE to be scheduled and the corresponding scheduling priority; and according to the maximum user scheduling number, available resources and the order of the scheduling priorities from high to low, orderly performing resource scheduling on the UE to be scheduled. The method can avoid phenomena of untimely power control, loss of synchronism of the UE and low beamforming performance of an antenna caused by not scheduling the UE for a long time, and can ensure to meet the QoS requirement of service and improve scheduling performance.

Description

technical field [0001] The invention relates to resource scheduling technology, in particular to a HSUPA resource scheduling method. Background technique [0002] In order to improve the uplink access capability, 3GPP introduces the HSUPA technology, the main goal of which is to improve the utilization efficiency of the uplink air interface capacity and enhance the cell throughput. The combination of HSDPA and HSUPA will realize high-speed symmetrical data communication and support services such as multimedia, video conferencing and VoIP. Similar to HSDPA, the key technologies of HSUPA include NodeB fast scheduling, adaptive modulation and coding AMC and hybrid automatic retransmission HARQ. [0003] The purpose of NodeB fast scheduling in HSUPA is to reasonably allocate uplink shared resources for UEs according to certain principles. A good scheduling algorithm can optimize system resource allocation and enable the system to obtain maximum throughput. In the scheduler, ho...
