Abstract: Devices, systems, and methods to reduce interference in heterogeneous networks having a plurality of access nodes, such as combinations of macro cells, micro cells, pico cells, femto cells, etc. are disclosed. Interference caused in sectors of two or more access nodes that face each other is minimized by dividing a total number of resource blocks into resource block sets that are uniquely numbered and allocated across each sector of each access node. The allocation is rotated based on a different time stamp or a different starting number, or may be a random sequence of sets per access node. These independent allocations for each access node generally distribute the interference across the system, and provide better interference reduction, resulting in an increase in system capacity per sector of each cell.

Abstract: A method and systems for managing paging congestion are described. A RAN may receive data indicating that a base station located at a particular geographic location is registering with the RAN. Responsive to receiving the data, the RAN may make a determination of whether a number of base stations in a particular tracking area that corresponds with the particular geographic location is greater than a threshold number of base stations. And responsive to making a determination that the number of base stations is greater than the threshold number of base station: the RAN may create a new tracking area having a new tracking area identity (TAI), the RAN may provision the base station with the new TAI rather than the particular TAI, and the RAN may provide the base station with a tracking area list that includes both the new TAI and a particular TAI identifying the particular tracking area.
