Method and device for allocating resources

Abstract

The invention discloses a method and device for allocating resources. The method comprises the steps of: determining the size of a first resource block group corresponding to a first resource allocation type in public resource regions according to the number of resource blocks of the public resource regions of carriers and a set first corresponding relationship; dividing the resource blocks of all the public resource regions of the carriers into one or more resource block groups according to the size of the first resource block group; determining the size of a second resource block group corresponding to the first resource allocation type in a special resource region according to the size of the first resource block group or the total number of the resource blocks of the carriers and the first corresponding relationship; and dividing the resource blocks of the special resource region of the carriers into one or more resource block groups according to the size of the second resource block group. According to the embodiment of the invention, the size of the resource block group is determined in accordance with the number of the resource blocks of the public resource regions, so that the scheduling process is simple, the resource repeated allocation rate is low, and the bandwidth resource is saved.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a resource allocation method and device. Background technique [0002] In a heterogeneous network, a carrier structure is: the control channel only occupies part of the bandwidth of the entire carrier, instead of using the control channel as a physical downlink control channel (Physical Downlink Control Channel) as in the Long Term Evolution (LTE) system. Channel (abbreviation: PDCCH) is extended or mapped to the system bandwidth of the entire carrier. Based on this carrier structure, the macro base station and the low power base station can use non-overlapping frequency bandwidths to transmit control channels (including PDCCH or PHICH or PCFICH) and common control channels PBCH or SCH. In the LTE system, the PDCCH control signaling schedules the time-frequency resources used by the terminal to receive or transmit data. For the resource a...

Problems solved by technology

[0005] Embodiments of the present invention provide a resource allocation method and device, which are used to solve the problems of high scheduling complexity, repeated resource allocation, and waste caused by the unequal size of common resource regions RBG in the prior art resource scheduling process. Realize the same RBG size in the common resource area of ​​carriers supporting different versions of terminal systems, the scheduling process is simple, the repeated resource allocation rate is low, and bandwidth resources are saved
