Problems solved by technology

[0003] This method of packet-by-packet application for packet-by-packet allocation of resources cannot meet the requirements of low delay for some real-time services, such as VoIP (Voiceover IP, voice over Internet technology); in addition, when the base station needs to serve multiple VoIP users, The signaling that needs to be processed by the base station will increase significantly, resulting in a delay in signaling processing

Embodiment Construction

[0016] The core idea of ​​the present invention is that the base station organizes a plurality of access terminals for real-time services into a group, and reserves a part of time-frequency resources for the group, and the base station allocates resources for the access terminals in units of groups.

[0017] Specifically include the following steps:

[0018] 1. The base station organizes multiple access terminals that start real-time services in the same sector into a "resource group".

[0019] Of course, the base station can establish multiple "resource groups" in the same sector, and assign a "group number" to each "resource group" in order to distinguish each "resource group".

[0020] 2. In the "resource group", the base station assigns each access terminal a "location number" in the group.

[0021] The access terminals in the "resource group" occupy the resources in the group according to the order of the "position number".

[0022] 3. The base station reserves time-fre...

Abstract

The invention discloses a resource allocation method. In a fourth generation mobile communication system, in particular an OFDMA system, a base station edits a plurality of accessing terminals for real-time service into a resource set and reserves a part of time-frequency resource; the base station uses a set as a unit for accessing terminals and resource allocation; after the accessing terminals receive a message of set resource allocation, the content of the message is resolved; and data sent by the base station are received from corresponding time-frequency resource of the message of the set resource allocation. The method is applied, can effectively reduce the time for resource allocation of the base station; and when the base station serves a plurality of the accessing terminals, the method can reduce signaling interaction between the base station and the accessing terminals so as to meet the requirement on low time delay of the real-time service.

Description

technical field [0001] The present invention relates to a mobile communication technology, in particular to a resource allocation method in an Orthogonal Frequency Division Multiple Access (OFDMA, Orthogonal Frequency Division Multiple Access) system. Background technique [0002] In the fourth generation mobile communication system, in order to provide more flexible services and utilize air resources more effectively, the access system usually allocates resources according to the QoS (Quality of Service, Quality of Service) requirements of various services. In an OFDMA system, resources are composed of "time-frequency" two dimensions. A commonly used resource allocation method is that the access terminal first applies for resources to the base station, and the base station then allocates corresponding resources. After a packet data packet is successfully transmitted on the allocated resources, the access terminal applies for resources to the base station again, and the bas...
