Problems solved by technology

[0017] In addition, the purpose of the DTM scheduling method is to make the final rate distribution within a predetermined maximum and minimum range, rather than the QoS rate request for each user terminal. Therefore, it cannot meet the different rate requests of each user terminal. Throughput of the whole system

Embodiment Construction

[0036] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0037] figure 1 A wireless communication system is shown, and the wireless communication system includes an access point 100 and a network controller 200 . In addition, the wireless communication system further includes multiple user terminals 300 . The access point 100 is connected to the network controller 200 via, for example, a transmission network. Under the control of the network controller 200, the access point 100 invokes different user terminals 300 at different times according to certain rules to establish communication links.

[0038] figure 2 shows a method according to the present invention that can be used for figure 1 The channel resource allocation device of the wireless communication system shown in . Actually, the channel resource allocation device is located in the access point 100 or the network controller 200 . ...

Abstract

The invention discloses a method for channel resource allocation in a wireless communication system, the wireless communication system includes an access point and a plurality of user terminals, the method includes the following steps: from the plurality of user terminals Each receives a request message, and the request message includes the service transmission rate requested by each of the plurality of user terminals on each sub-channel and the transmission rate allocated to each user terminal, so as to calculate each The ratio between the service transmission rate requested by the user terminal on each sub-channel and the transmission rate allocated to each user terminal; according to the ratio, determine the user terminal corresponding to the maximum ratio; and, during the next transmission , calling the user terminal with the largest ratio. According to the method of the present invention, the throughput of the whole system is improved on the basis of satisfying different rate requests of each user terminal.

Description

technical field [0001] The present invention relates to resource allocation in a wireless communication system, in particular to a channel resource allocation method and equipment in a wireless communication system. Background technique [0002] With the rapid development of Internet, e-mail, multimedia, etc., the requirements for data services are increasing day by day. In order to support these packet data services, limited radio resources must be utilized in an optimal manner to increase capacity and guarantee Quality of Service (QoS). How to ensure the priority and fairness of different services is very important for channel resource allocation in a wireless communication system. [0003] In the existing CDMA system, there are the following resource scheduling methods: [0004] a. Maximum C / I scheduling, that is, the scheduler selects the UE with the highest instantaneous C / I. This scheduling method is very simple, it only allocates resources according to the gain of ...
