Method for resource management in a cellular communication network and resource management system

Abstract

A method for resource management in a cellular communication network, wherein the network includes at least one base station per cell for a plurality of cells that operates in TDD (Time Division Duplex) transmission mode, wherein the base stations implement a respective UL/DL configuration mode in which frames are composed of a specific sequence of downlink DL, uplink UL and special S subframes, is characterized in that the base stations are operated such that neighboring base stations with adjacent and/or overlapping coverage areas employ different UL/DL configuration modes, wherein interference between neighboring base stations is taken account of by implementing power control on a subframe basis. Furthermore, a resource management system for use in a cellular communication network is described.

1 . A base station of a cell that operates in TDD (Time Division Duplex) transmission mode, wherein the base station is configured with a plurality of UL/DL configurations which each include a DL subframe, an UL subframe and a special subframe, the UL/DL configurations vary between the cell and a neighboring cell, and the base station transmits and receives a UL/DL configuration to and from a base station of the neighboring cell. 
     
     
         2 . A communication method in a base station of a cell that operates in TDD (Time Division Duplex) transmission mode, wherein the base station is configured with a plurality of UL/DL configurations which each include a DL subframe, an UL subframe and a special subframe, the UL/DL configurations vary between the cell and a neighboring cell, the method comprising:
 transmitting a UL/DL configuration to a base station of the neighboring cell; and   receiving the UL/DL configuration from the base station of the neighboring cell.
