Patent ID: 8843070

Claim:
A method for transmitting interference control signaling in a wireless communication system, comprising: selecting by a base station Sub-band Price Indication (SPI) values of a part of sub-bands in a sub-band set in which frequency reuse factor is Reuse=n>1 according to SPI value selecting regulation of sub-bands, forming interference control signaling, and transmitting the interference control signaling to terminals of the base station through a downlink channel; wherein the SPI values of a part of sub-bands refer to SPI values of k n −1 sub-bands in a sub-band set in which the frequency reuse factor is Reuse=n>1, wherein k n is the number of the sub-bands in the sub-band set in which the frequency reuse factor is Reuse=n>1; or the SPI values of a part of sub-bands refer to SPI values of sub-bands corresponding to L n −1 transmission power levels in a sub-band set in which the frequency reuse factor is Reuse=n>1, wherein L n is the number of transmission power levels in the sub-band set in which the frequency reuse factor is Reuse=n>1, wherein the SPI value selecting regulation of sub-bands is that the base station selects SPI values of k n −1 sub-bands from the sub-band set in which the frequency reuse factor is Reuse=n>1 through the transmission power of the sub-bands or the serial numbers of the sub-bands according to configuration information; or the SPI value selecting regulation of sub-bands is that the base station selects SPI values of sub-bands of L n −1 transmission power levels from the sub-band set in which the frequency reuse factor is Reuse=n>1 through the transmission power of the sub-bands or the serial numbers of the sub-bands according to configuration information; and wherein the configuration information comprises transmission power of the sub-bands in a sub-band set in which the frequency reuse factor is Reuse=n≧1, the SPI values of sub-bands in a sub-band set in which Reuse n=1 and the sum of the SPI values of all the sub-bands in the sub-band set in which Reuse=n>1.
