Method and system for collocating group resource, and communicator

Abstract

The embodiment of the invention relates to a method and a system for collocating group resource, and a communicator. The method comprises the steps of: analyzing whether need to collocate a supplement resource besides the normal resource to each user in a user group, generating a user bitmap according to the user group, arranging a supplement resource marker on the user position in the user bitmap corresponding to the user requiring the supplement resource, generating the resource collocation information of all the resources required by the user who needs the supplement resource, generating a resource distributing bitmap by using the resource collocation information according to the sequence of the user who needs the supplement resource in the user bitmap, generating group source collocating information which contains the user bitmap and the resource distributing bitmap; and coding and sending the group source collocating information. The method and the system for collocating group resource, and the communicator of the embodiment of the invention efficiently save the cost of control signaling transmission.

Description

technical field [0001] The present invention relates to communication technology, in particular to a group resource allocation method and system, and a communication device. Background technique [0002] Worldwide Interoperability for Microwave Access (WiMAX), also known as Wireless Metropolitan Area Network, is a "last mile" wireless connection solution for enterprises and home users. It can be used in the field of data communication To achieve high coverage, it can cover a range of about 25-30 kilometers. This technology is based on IEEE802.16 series broadband wireless standards, including IEEE802.16, IEEE802.16a, IEEE802.16c, IEEE802.16d, IEEE802.16e, IEEE802.16f, IEEE802.16g and IEEE802.16m. VoIP (Voice over Internet Protocol, hereinafter referred to as: VoIP) is a very important service in a WiMAX wireless network, and this service has many different voice coding formats, such as Adaptive Multi-Rate (Adaptive Multi-Rate, hereinafter referred to as: AMR ) and Enhanced ...

AI Technical Summary

Problems solved by technology

Therefore, once VoIP needs to send SIP signaling, the original group resource assignment message can only allocate less resources and cannot transmit SIP signaling in a timely manner.

Of course, the base station (Base Station, hereinafter referred to as: BS) can perform resource allocation through an additional temporary resource assignment message, but the user needs to parse two resource assignment messages, one of which is the original group resource assignment message, and the other 1 is a temporary resource assignment message, which needs to increase the amount of data processed by the mobile station (Mobile Station, hereinafter referred to as: MS) and consume the power of the MS

At the same time, the minimum control channel transmission unit required by the temporary resource assignment message is about 48 bits to carry resource allocation information, modulation and coding information, etc., which increases the overhead of control signaling transmission
