Embodiment Construction

[0061] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with specific implementation methods and accompanying drawings.

[0062] The core idea of ​​the present invention is that after the simple mapping from DVRB to PRB is given, continuous DVRB resources are allocated to each UE, and the indication method of continuous resource allocation is adopted, that is, if the DVRB resources occupied by users are allocated continuously, then the allocation is carried out. When indicating, only need to indicate the current scheduling UE ID, and the start and end positions of the continuous DVRB resource blocks allocated for each UE, the UE can determine the position of the allocated DVRB resource blocks, and then the UE according to the mapping from DVRB to PRB, Get the actual physical resources it occupies.

[0063] The resource allocation method and indication ...

Abstract

This invention relates to a distribution and instruction method for system resources including: applying a resource DVRB continuous distribution method for the dispatched scattered UE from the given simple mapping from DVRB to PRB and indicating a first UE to occupy the start position of the DVRB and all UE to occupy the length of the DVRB when instructing each UE to distribute the resource, or distributing the continuous resource from long to short according to the length occupied by UE so as to minimize the spending of the DVRB resource distribution instruction signaling in the way of combined coding of control signaling of scattered users then to determine physical resource occupied by UE according to the mapping relation from DVRB to PRB.

Description

technical field [0001] The present invention relates to communication technology, in particular to resource allocation and indication technology of communication system. Background technique [0002] At present, in communication systems, in order to improve the capacity and spectrum utilization efficiency of broadband wireless communication systems, multi-carrier technology is often used. The basic idea is to divide a broadband carrier into multiple sub-carriers and transmit data simultaneously on multiple sub-carriers. In the application, the width of the subcarrier is required to be smaller than the coherent bandwidth of the system channel, so that the fading on each subcarrier is flat fading, which can reduce the crosstalk between symbols, and does not require complicated channel equalization, which is suitable for high-speed data transmission. [0003] There are many forms of multi-carrier technology, such as Orthogonal Frequency Division Multiplexing (OFDM, Orthogonal F...
