Embodiment Construction

[0036] One, one of the present invention, base station scheduler

[0037] Such as figure 1 As shown, the base station scheduler of the present invention divides the base station scheduler into sequentially connected scheduling priority module 1, resource allocation module 2 and Signaling selection module 3.

[0038] The interfaces between the three modules are:

[0039] A scheduling priority list of the UE between the scheduling priority module 1 and the resource allocation module 2;

[0040] The scheduling command (Sgi) list can be set between the resource allocation module 2 and the command option module 3 according to limited AG commands, so as to reduce the calculation of the resource allocation module and effectively use the AG commands.

[0041] 1. Scheduling priority module

[0042] Fully consider the characteristics of time-division scheduling of multi-user systems, the module according to the input from the UE status report (such as: scheduling information (SI), m...

Abstract

The related BS scheduler for HSUPA comprises: a scheduling PRI module to generate a PRI table for all UE of every subzones controlled by same BS, a resource allocation module to right generate scheduling command for control wireless resource allocation, with respect to the PRI table and meeting business QoS and improving resource utility; and a command selecting module to select and output command according to all of UE scheduling command and scheduling period and down signaling channel management message. This invention improves scheduling and HSUPA system performance, and can avoid congestion for all UE on one BS to reduce loading.

Description

technical field [0001] The invention relates to a 3G (3rd generation mobile communication) mobile communication system, in particular to a base station scheduler, a resource allocation module and a scheduling control method for HSUPA. Background technique [0002] As a 3G uplink enhancement technology, HSUPA mainly aims at improving system uplink performance and improving user experience. In order to achieve this purpose, HSUPA (High speed uplink packet access, high speed uplink packet access) adopts technologies such as scheduling strategies with Node B (base station). [0003] In HSUPA, the basic process based on base station scheduling is: the base station generates corresponding downlink commands according to relevant uplink information and sends them to user terminals. The terminal performs correct data transmission according to the downlink scheduling command. [0004] During the transmission process of HSUPA, the terminal will report its status to the base station a...
