Problems solved by technology

However, this method is to preset multiple groups of time slots and code channel combinations, and allocate the closest group to the user according to the user rate request. waste of resources
[0005] To sum up, the resource allocation method in the prior art will cause waste of resources when carrying signaling and services with a small amount of data

Embodiment Construction

[0052] In order to make the object, technical solution and advantages of the present invention clearer, the solutions of the present invention will be further described in detail below with reference to the accompanying drawings and examples.

[0053] figure 1 It is a flowchart of an embodiment of a TD-SCDMA system-based resource allocation method provided by the present invention. Such as figure 1 As shown, the method includes the following steps:

[0054] Step 101, determining a set of resources to be allocated.

[0055] Methods for determining the set of resources to be allocated include:

[0056] Step 1011, in the resource pool, search for unoccupied code channels in each time slot sequentially according to the order of time slots, and obtain all idle resource units in the resource pool, and each idle resource unit is an unoccupied one in the resource pool A pair of continuous SF=16 code channels in a time slot.

[0057] The idle resource unit is an unoccupied resourc...

Abstract

The invention discloses a TD-SCDMA (Time Division-Synchronous Code Division Multiple Access) system-based resource allocation method. The method comprises the following steps of: A, determining a resource collection to be allocated; B, determining a total number of idle resource units needed by a current priority queue to be scheduled; C, determining available resource blocks of different shapes according to the determined total number of the idle resource units needed by the current priority queue to be scheduled; and D, selecting required resource blocks from the resource collection to be allocated according to the determined available resource blocks of different shapes, and further, allocating the required resource blocks to users. With the adoption of the method disclosed by the invention, the resource waste of signaling and a service with a relatively-small data size can be reduced.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a resource allocation method based on a TD-SCDMA system. Background technique [0002] When the Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system is developed to the High Speed ​​Packet Access Plus (HSPA+) system, the idea of ​​sharing is adopted, and its control channel and traffic channel share the entire Services with small data volumes such as signaling are allocated resources in the same resource pool. For the downlink, the power is fixed, and the resources that can be allocated mainly include time slots and code channels. The downlink supports a total of 16 code channels with spreading factor (SF) = 16. The number of downlink time slots varies due to different configurations. difference, but the number of slots is less than the number of code channels. [0003] At present, there are mainly two resource allocation methods in the system: code divi...
