1. A method for wireless communications as implemented in a first base station comprising:
- transmitting a neighbor topology request message to a second base station, said neighbor topology request message soliciting neighbor topology information regarding one or more neighbors associated with said second base station;
receiving, from the second base station, a neighbor topology response message comprising said neighbor topology information regarding one or more neighbors associated with said second base station; and
partitioning one or more network resources according to said received neighbor topology response message between said first and second base stations.

Abstract
A description of an interface and a system/method is provided to combine frequency, time and power domain resource partitioning between neighbor small cells whereby these cells can execute the resource partitioning, without resorting to a centralized management system, simply by periodically sharing topology-related and interference related information with one another. Such a scheme allows resource partitioning to be executed in real-time as more small cells are deployed into the network.

20. A method for wireless communications as implemented in a first base station comprising:
-
sending a neighbor topology request message to a second base station, said neighbor topology request message comprising neighbor topology information associated with said first base station and a solicitation for neighbor topology information associated with said second base station; receiving, from the second base station, a neighbor topology response message, said neighbor topology response message comprising said neighbor topology information associated with said second base station; and partitioning one or more network resources according to said neighbor topology information associated with said first base station and said neighbor topology information associated with said second base station.

21. A method for wireless communications as implemented in a first base station comprising:
-
transmitting a first neighbor topology request message to a second base station and a second neighbor topology request message to a third base station, said first and second neighbor topology request messages soliciting neighbor topology information regarding one or more neighbors associated with said second base station and third base station, respectively; receiving, from the second base station, a first neighbor topology response message comprising said neighbor topology information regarding one or more neighbors associated with said second base station, and receiving, from the third base station, a second neighbor topology response message comprising said neighbor topology information regarding one or more neighbors associated with said third base station; determining, from said first and second neighbor topology response messages that said first base station has more first degree neighbors than both said second and third base stations; and reducing power of said first base station based on said determination. - View Dependent Claims (22)

23. A method for wireless communications as implemented in a first base station comprising:
-
transmitting a first neighbor topology request message to a second base station and a second neighbor topology request message to a third base station, said first and second neighbor topology request messages soliciting neighbor topology information regarding one or more neighbors associated with said second base station and third base station, respectively; receiving, from the second base station, a first neighbor topology response message comprising said neighbor topology information regarding one or more neighbors associated with said second base station, and receiving, from the third base station, a second neighbor topology response message comprising said neighbor topology information regarding one or more neighbors associated with said third base station; determining, from said first and second neighbor topology response messages that said first base station has same first degree neighbors as said second base station, but more first degree neighbors as said third base station; and reducing power of either said first base station or said second base station based on said determination and at least one of the following;
total SINR received by each base station, distance-wise closeness of said first base station'"'"'s first degree neighbors, and distance-wise closeness of said second base station'"'"'s first degree neighbors. - View Dependent Claims (24)
