Parameter transmission method and device for interference coordination, and interference coordination method and device

An interference coordination method, applied to a second Transmission Point (TP), the method comprising:

• receiving, by the second TP, a set of shared parameters from a first TP, wherein the second TP is adjacent to the first TP, the set of shared parameters is a parameter information set defined on a specified part of resources after the first TP specifies the part of resources in all available resources of the first TP, and the set of shared parameters are used for performing interference coordination between the first TP and the second TP;
• and
• scheduling, by the second TP, a user terminal managed by the second TP according to the set of shared parameters;
• wherein the set of shared parameters is information defined on the specified part of resources by the first TP, wherein the information comprises at least one of:
• N5 Rank Indications (RIs), and N6 Precoding Matrix Indicators (PMIs);
• where N5 and N6 are all positive integers more than or equal to 1;
• wherein the specified part of resources comprise one of:
• a preset subframe set of the first TP, wherein the preset subframe set is one of:
• an Almost Blank Subframe (ABS) set and a non-ABS set, and the available resources of the first TP are composed of all subframes;
• and one cell, specified by the first TP, in multiple cells belonging to the first TP, wherein the available resources of the first TP are composed of all cells belonging to the first TP.

A parameter transmission device for interference coordination, applied to a first Transmission Point (TP), the device comprising:

• a specification component, configured to specify a part of resources in all currently available resources of the first TP;
• a definition component, configured to define a set of shared parameters on the specified part of resources, wherein the set of shared parameters are used for performing interference coordination between the first TP and at least one second TP adjacent to the first TP;
• and
• a sending component, configured to send the set of shared parameters to the at least one second TP;
• wherein the set of shared parameters is information defined on the specified part of resources by the first TP, wherein the information comprises at least one of:
• N5 Rank Indications (RIs), and N6 Precoding Matrix Indicators (PMIs);
• where N5 and N6 are all positive integers more than or equal to 1;
• wherein the specified part of resources comprise one of:
• a preset subframe set of the first TP, wherein the preset subframe set is one of:
• an Almost Blank Subframe (ABS) set and a non-ABS set, and the available resources of the first TP are composed of all subframes;
• and one cell, specified by the first TP, in multiple cells belonging to the first TP, wherein the available resources of the first TP are composed of all cells belonging to the first TP.
