Method and device for allocating resource

Abstract

The embodiment of the invention discloses a method and a device for allocating resource. The method comprises the following steps: generating a resource allocating message, allocating the resources requiring the persistent allocation by means of a bitmap in the resource allocating message, and allocating the resources requiring the non-persistent allocation by means of a channel tree in the resource allocating message; and sending the resource allocating message. The embodiment of the invention realizes the mixed allocation way of the bitmap allocation used for the resources requiring the persistent allocation and the channel tree allocation used for the resources requiring the non-persistent allocation, and effectively reduces the allocation outgoings compared with the allocation way of the channel tree allocation uniformly used for the resources requiring the persistent allocation and the resources requiring the non-persistent allocation and the allocation way of the bitmap allocation uniformly used for the resources requiring the persistent allocation and the resources requiring the non-persistent allocations.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a resource allocation method and equipment. Background technique [0002] With the development of the wireless communication field, the mobile network of the future mobile communication system provides different services, such as multiple services such as voice and data. Due to the increasing demands of various mobile users on the diversity of real-time and non-real-time services, radio resources are very precious, and how to design an efficient radio resource management solution becomes very important. [0003] In a wireless communication system, uplink data transmission means that MS (Mobile Station, mobile terminal) sends data to BS (Bastion Station, base station), and MS needs to apply for data transmission resources from front-end base station BS before performing uplink data transmission. , data transmission can only be performed after resources allocated by...

Problems solved by technology

[0010] In the continuous assignment process, due to the asynchronous release of each resource, it will cause resource discontinuity, and some "resource holes" will appear

In the channel tree-based assignment method, these empty BSs cannot be assigned with one assignment message, but must be assigned with multiple assignment messages, which increases the assignment overhead

However, although bitmap assignment can be used to assign multiple non-continuous resources at one time, the assignment overhead is very high, especially for non-continuous assignments with high assignment frequency.
