Radio resource reuse method, base station device, terminal device and radio communication system

Abstract

Disclosed is a radio resource reuse method, a base station device, a terminal device, and a radio communication system. The system at least comprises two adjacent cells C(i=1, 2), using time-frequency resource, denoted as S for communication, which is divided into at least two resource units, each of the resource units being one time-frequency resource block. The method comprises: dividing the time-frequency resource S into N non-overlapping resource groups, denoted as RG(n=1, 2, . . . , N), N being an integer larger than 1, and each of the resource groups comprising at least two of the resource units; and dividing RG(n=1, 2, . . . , N), in cell C(i=1, 2), into two non-overlapping portions, of which, one portion is configured with an upper power density limit hand termed a primary sub-resource group of RG, and the other portion is configured with an upper power density limit land termed a secondary sub-resource group of RG, wherein the sub-resource groups have the following relationships in terms of upper power density limit thereof: l/h<l/h< . . . <l/h≤1, wherein the primary sub-resource groups of the two adjacent cells C(i=1, 2) do not overlap with each other in each resource group.
