Problems solved by technology

On the uplink, UL-MAP only assigns uplink resource allocation information for a single mobile station connection. When there are a large number of IP voice services (VoIP, Voice over Internet Protocol) real-time user connections in the uplink, it is necessary to A large number of small block resource allocations for each user, at this time, the overhead of UL-MAP messages will cause a great burden on the system

Embodiment Construction

[0025] According to the present invention, the VoIP real-time service packets of the same coder are sent at a fixed period and have a fixed length. Assign uplink resources.

[0026] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, taking the OFDMA-based broadband wireless access system as an example.

[0027] refer to figure 1 As shown, the function of the mask sequence in the present invention is further described in detail.

[0028] In the OFDMA-based mobile WiMAX broadband wireless access system, resource allocation is performed on time-frequency two-dimensional resources. From the perspective of the frequency domain, the data of each service connection occupies a certain orthogonal subcarrier resource; from the perspective of the time domain, the data of each service connection occupies a certain Orthogonal Frequency Division Multiplexing (OFDM) symbol. The group-based uplink resource assig...

Abstract

The invention discloses a method for reducing allocated cost for uplink resource comprising steps: mobile station initiates a VoIP service connection request to base station; base station allocates group resource allocation information for VoIP service, allocates the VoIP service of same modulated coding style in same group to same uplink burst resource block according to the group resource allocation information, and notifies mobile station of group of the information of uplink burst resource block via uplink resource allocation message; the mobile station decodes the uplink resource allocation message, and determines concrete position of the VoIP service to which the mobile station corresponds in the uplink burst resource block according to uplink resource allocation message. The invention guarantees group user positioned in different channel condition adopts different modulation and coding mode and be allocated with different uplink resource, also guarantees talking quality of VoIP service.

Description

technical field [0001] The present invention relates to a broadband wireless communication technology, in particular to a method for reducing uplink resource assignment overhead. Background technique [0002] The downlink of next-generation mobile communication systems such as mobile WiMAX is mainly based on the multiple access mode of Orthogonal Frequency Division Multiple Access (OFDMA). Under a given system bandwidth, from the perspective of the frequency domain, different Users achieve the purpose of multiple access by occupying a certain amount of orthogonal sub-carrier resources. [0003] In a mobile WiMAX system, data packets connected by different users are transmitted on certain orthogonal sub-carrier resources. In the downlink, the DL_MAP message includes the resource allocation information of each downlink burst data packet, indicating the position of the data burst where the corresponding connection is located in the mobile station. Since a downlink burst often...
