1. A method for operating an interference coordinating entity (ICE), the method comprising:
- partitioning, by the ICE, a cloud radio access network (CRAN) cluster by;
grouping, according to a partitioning criterion, transmission points (TPs) serving user equipments (UEs) into at least one virtual transmission point (V-TP) to produce a V-TP set, wherein the UEs to be served are preferably offset from a V-TP boundary;
adjusting the partitioning criterion; and
repeating the partitioning to produce a plurality of V-TP sets;
saving, by the ICE, V-TP information to a memory;
for each V-TP set,scheduling the UEs that can be served by the TPs for the V-TP set, anddetermining a merit measurement for the UEs that have been scheduled for the V-TP set;
selecting one of the merit measurements to determine a V-TP configuration for the CRAN cluster; and
causing, by the ICE, at least one of the TPs to communicate to at least one of the UEs according to parameters of the V-TP configuration.

Abstract
A method for operating an interference coordinating entity (ICE) includes partitioning, by the ICE, a cloud radio access network (CRAN) cluster by grouping transmission points (TPs) serving user equipments (UEs) in accordance with a partitioning criterion into at least one virtual transmission point (V-TP) to produce a V-TP set. The UEs to be served are preferably offset from a V-TP boundary. The method also includes saving, by the ICE, V-TP information to a memory.

17. An interference coordinating entity (ICE) comprising:
-
a processor configured to partition a cloud radio access network (CRAN) cluster by grouping, according to a partitioning criterion, transmission points (TPs) serving user equipments (UEs) into at least one virtual transmission point (V-TP) to produce a V-TP set, wherein the UEs are preferably offset from a V-TP boundary; and a memory operatively coupled to the processor, the memory configured to store V-TP information; and wherein the processor is configured to partition the CRAN cluster into a plurality of V-TP sets, to, for each V-TP set, schedule the UEs that can be served by the TPs for the V-TP set, to, for each V-TP set, determine a merit measurement for the UEs that have been scheduled for the V-TP set, and to select one of the merit measurements to determine a V-TP configuration for the CRAN cluster; and wherein the processor is further configured to cause at least one of the TPs to communicate to at least one of the UEs according to parameters of the V-TP set. - View Dependent Claims (18, 19, 20, 21, 22, 23)

24. A communications network comprising:
-
a plurality of cloud radio access network (CRAN) clusters, each CRAN cluster including a plurality of transmission points (TPs) configured to serve user equipments (UEs), the plurality of TPs partitioned, according to a partitioning criterion, into a virtual transmission point (V-TP) set of at least one V-TP, wherein the UEs are preferably offset from a V-TP boundary, and wherein each V-TP is a joint processing unit; a first interference coordinating entity (ICE) operatively coupled to a first one of the CRAN clusters, the first ICE configured to partition the first one of the CRAN clusters according to a corresponding V-TP set, and further configured to cause at least one of the TPs to communicate to at least one the UEs according to parameters of the corresponding V-TP set; and a second ICE operatively coupled to a second one of the CRAN clusters, the second ICE configured to partition network resources of the communications network into a plurality of disjoint transmission resource units, and to allocate one or more transmission resource units to each CRAN cluster so that adjacent CRAN clusters are only allocated the same network resource unit if different priority levels are also assigned to the adjacent CRAN clusters. - View Dependent Claims (25, 26, 27, 28)
