METHOD AND DEVICE FOR ALLOCATING RESOURCE

The present invention provides a method and a device for allocating resource. The method comprises: determining information of a second Physical Random Access Channel (PRACH) resource of at least one second cell adjacent to a first cell; and allocating a first PRACH resource for the first cell according to the information of the second PRACH resource, wherein the first PRACH resource and the second PRACH resource are staggered on time domain and/or frequency domain. According to the embodiment of the present invention, since the first PRACH resource allocated for the first cell and the second PRACH resource of the adjacent second cell are staggered on time domain and/or frequency domain, the same frequency interference on the first PRACH resource by the second PRACH resource can be reduced, the false alarm probability caused by the same frequency interference can be reduced, and thus the random access performance and the access success rate can be increased.
