Embodiment Construction

[0032] The basic idea of ​​the present invention is that for multiple component carriers in LTE-A, the virtual resource blocks on each component carrier are individually interleaved, and then the different virtual resource blocks of each carrier obtained by interleaving are carried out as a whole. After the interleaving is completed, the rearranged virtual resource blocks are mapped to physical resource blocks, so that the LTE-A system can realize resource mapping in a large bandwidth environment, and at the same time increase the frequency diversity. The existing LTE downlink distributed resource mapping method is adopted, thereby reducing the impact on the LTE system and ensuring system compatibility.

[0033]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only some, not all, em...

Abstract

The invention relates to a method and a device for mapping resources. The method comprises the following steps of: separately interlacing a virtual resource block on each carrier in a plurality of carriers, interlacing between the carriers by using a first and a second virtual resource blocks of each carrier in the carriers acquired by interlacing as an integrate body, and mapping the rearranged virtual resource blocks onto a physical resource block after the interlacing is finished. The method and the device of the invention can map resources in an LTE-A system under a big band width condition, increases the frequency diversity, decreases the influence on the LTE system by partially using a downlink distribution type resource mapping mode of the current LTE, and ensures the system compatibility.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a method and device for realizing resource mapping. Background technique [0002] At present, in the existing LTE (Long Term Evolution, Long Term Evolution) system, when sending downlink data, it often continues to transmit through a single carrier; therefore, when allocating downlink resources, you can use a non-frequency hopping method or a frequency hopping method, that is, LVRB ( Localized Virtual Resource Block, localized virtual resource block) mode and DVRB (Distributed Virtual Resource Block, distributed virtual resource block) mode; [0003] Wherein, when the LVRB is allocated, the physical resource block can be allocated directly according to the virtual resource block, that is, the assigned VRB (Virtual Resource Block, virtual resource block) number is consistent with the PRB (PhysicalResource Block, physical resource block) number, and The same i...
