Problems solved by technology

Since assignment messages belong to the category of signaling, strong transmission power is required for transmission. Therefore, frequent sending of reuse assignment messages tends to increase signaling overhead and cause waste of power resources.

Embodiment Construction

[0022] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0023] See figure 1 As shown, the reuse assignment method provided by the embodiment of the present invention mainly includes the following steps:

[0024] Step 101: The base station continuously assigns the reused resources to the reused users through the reuse assignment message, and allocates the new packet indication channel F-SPCH for the reused users;

[0025] Step 102: The reused user detects the status carried on the F-SPCH, and decides whether to receive the data packet transmitted on the reused resource according to the detection result.

[0026] Wherein, the resource generally refers to the base node BaseNode; the reuse assignment message is SPFLAM, SP MCW FLAM1, or SP SCW FLAM. The base station informs the reused user of the location of the ...

Abstract

The invention provides a reuse distribution method, comprising that a base station continuously distributes reuse resource to a reuse subscriber by a reuse distribution message and distributes a new packet indicator channel for the reuse subscriber, the reuse subscriber detects states which are carried on a new packet indicator channel and decides whether a data packet which is transmitted on the reuse resource is received according to a detection result. Furthermore, the invention also provides a reuse distribution system, comprising a base station used for sending a reuse distribution message to a user equipment, continuously distributing the reuse resource to the reuse user equipment, distributing the new packet indicator channel to the user equipment and sending the position of the distributed new packet indicator channel to the reuse user equipment, and the reuse user equipment which is used for detecting the states which are carried on the new packet indicator channel and deciding whether the data packet which is transmitted on the reuse resource is received according to the detection result. The invention can realize the continuous distribution of the reuse resource, reduce signalling expense and save power resource.

Description

Technical field [0001] The present invention relates to a resource allocation technology in wireless communication, in particular to a method and system for reusing assignment. Background technique [0002] Air Interface Evolution (AIE) is a wireless access technology proposed by the third-generation mobile communication project organization 3GPP2, which uses Orthogonal Frequency Division Multiplexing (OFDM) technology as the basis of the physical layer. In the AIE system, the forward resource is divided into several basic nodes (BaseNode). Taking the 5M bandwidth as an example, the forward resource is divided into approximately 32 BaseNodes. After removing the guard band, there are approximately 28 BaseNodes used for data transmission, of which at least 3 BaseNodes are used to transmit control signaling. The base station assigns resources other than the resources occupied by the control signaling to the user through the assignment message. The assignment message is transmitted i...
