Method and device for allocating resources

Abstract

The present invention discloses a resource allocation method and apparatus, wherein the method comprises: according to the number of resource blocks in a common resource area of a carrier and a set first corresponding relationship, determining a first resource block group size corresponding to a first resource allocation type in the common resource area; and according to the first resource block group size, dividing all resource blocks in the common resource area of the carrier into one or more resource block groups; according to the first resource block group size, or according to the total number of resource blocks of the carrier and the first corresponding relationship, determining a second resource block group size corresponding to the first resource allocation type in the dedicated resource area; and according to the second resource block group size, dividing resource blocks in the dedicated resource area of the carrier into one or more resource block groups. The embodiments of the present invention determine the resource block group size according to the number of resource blocks in the common resource area, which simplifies scheduling process, reduces repeated resource allocation, and saves bandwidth resource.

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
