Abstract

The invention discloses a method and system for coordinating inter-cell interference, and relates to the field of mobile communication. The method includes: the first mobile terminal sends the uplink physical resource block occupancy information to the second mobile terminal through the mobile ad hoc network; wherein the first mobile terminal is located at the edge of the first cell adjacent to the second cell The second mobile terminal is a mobile terminal located in the second cell, and the mobile ad hoc network includes the first mobile terminal and the second mobile terminal; the second mobile terminal uses the uplink physical resource blocks of the first mobile terminal The occupation information is sent to the base station of the second cell, so that the base station of the second cell allocates the physical resource blocks not occupied by the mobile terminal at the edge of the first adjacent cell to the mobile terminal at the edge of the second cell adjacent to the first cell. In this way, the same-frequency interference between cells is reduced.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a method and system for inter-cell interference coordination. Background technique [0002] In LTE co-frequency networking, co-frequency interference will occur between adjacent cells. At present, the main technology for anti-co-frequency interference in the LTE system is inter-cell interference coordination ICIC technology. [0003] In the 3GPP standard, the dynamic ICIC technology is adopted in the uplink, and the high interference indication HII and the overload indication OI information are transmitted through the X2 interface. The HII is used to point out the physical resource block PRB allocated to the edge user that may cause relatively large interference, and to avoid collision and reduce interference through resource scheduling. OI is used to point out those PRBs that have been greatly interfered to prevent them from being allocated to edge users. When the...
