Problems solved by technology

However, TD-SCDMA is a Time Division Duplex (TDD) mode system. There is a big difference in HSUPA technology between TDD mode and FDD mode. The HSUPA scheduler in TDD mode cannot Neighboring cell interference level lowers the transmission rate of neighboring cells, but only by controlling the possible interference of scheduled UEs to neighboring cells, so as to achieve the controllable level of neighboring cell interference in the entire system
It can be seen that the existing FDD HSUPA scheduling method cannot be directly used to realize HSUPA scheduling in TD-SCDMA system
[0005] Moreover, due to the differences in the processing of uplink and downlink, the existing high-speed downlink packet access (HSDPA) scheduling method cannot be directly used to implement HSUPA scheduling
In addition, no scheduling method related to HSUPA in TDD mode has been found in the currently published patents and literature

Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0037] The main idea of ​​the present invention is to estimate the resources requested by the UE to be scheduled and the interference that will be generated when it is scheduled, and then according to the estimated resources requested by the UE and the interference that will be generated when it is scheduled, within the corresponding threshold The UEs that can be scheduled are determined in descending order of priority according to the determined transmission sequence, and finally, corresponding resources are granted to the UEs that can be scheduled according to the estimated resources requested by the UEs. Because the present invention pre-estimates the resources requested by the UE to be scheduled and the interference that will be generated when it is ...

Abstract

The invention discloses a method for dispatching a high-speed uplink package access system (HSUPA), comprising the following steps of: firstly, estimating the resource requested by UE to be dispatched and the interference generated after the UE is dispatched; subsequently, according to the estimated resource requested by the UE and the interference generated when the UE is dispatched, determining the UE that can be dispatched in corresponding threshold from high to low according to the determined sending sequence priority; and finally, according to the estimated resource requested by the UE, authorizing corresponding resource to the UE that can be dispatched. The method can reasonably distribute the time-slot code-channel physical resource and effectively control the interference in the cell and the interference to the adjacent cells during the dispatching process.

Description

technical field [0001] The present invention relates to high-speed uplink packet access (HSUPA) technology, in particular to an HSUPA scheduling method. Background technique [0002] In order to meet the development needs of high-speed data services in mobile networks, the Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system introduces HSUPA technology, and the Enhanced Uplink Dedicated Channel (E-DCH) is a newly added uplink channel of HSUPA technology. The key technologies of E-DCH include: adaptive modulation and coding (AMC), hybrid automatic repeat request (HARQ) and uplink fast scheduling controlled by the base station (Node B). [0003] The HSUPA scheduler in the Node B is used to control the fast uplink scheduling, which includes: rate scheduling (the rate can also be equivalent to the corresponding power according to a certain relationship) and physical resource scheduling, wherein the former can quickly control users based on the interference l...
