Claim:
1. A base station for reducing inter-cell interference, comprising: at least one processor; and a non-transitory storage device storing one or more programs which, when executed by the at least one processor, cause the at least one processor to: detect low interference indicators (LIIs), wherein the LIIs comprise low interference physical resource blocks (PRBs); and allocate the low interference PRBs in the LIIs that are not used by user equipment (UE) of a cell served by the base station (served cell) to cell edge UE of the served cell; wherein the low interference PRBs in the LIIs comprise PRBs that are allocated to cell center UE of a neighboring cell by a neighboring station for downlink transmission, and the one or more programs further cause the at least one processor to: for downlink transmission, when the LIIs are not detected, or when the LIIs are detected but the low interference PRBs in the LIIs are all used by the UE of the served cell, allocate remaining PRBs that are not used by the UE of the served cell to cell edge UE of the served cell after ruling out high interference PRBs in relative narrowband transmission power (RNTP) messages.
