Abstract: When a base station is serving a UE on a first RF carrier, the base station encounters a trigger to add to the UE's air interface connection a second RF carrier. The base station then decides based at least in part on a measure of RF performance of communication between the base station and the UE on the first RF carrier, whether the second RF carrier that the base station will add to the UE's air interface connection should be a TDD carrier or rather an FDD carrier. And the base station then reconfigures the UE's air interface connection to add a second RF carrier in accordance with the decision. The base station then serves the UE concurrently on the first RF carrier and the second RF carrier.

Abstract: A method and apparatus to use multiple pilot signals of different transmission power levels in a wireless communication system. A base station may broadcast in its coverage area at least two different pilot signals concurrently with each other but at different transmission power levels than each other. One of these pilot signals, transmitted at a normal pilot transmission power level for instance, may be for receipt and evaluation by certain UEs served by the base station, such as UEs that are not set to receive beamformed transmission of bearer traffic from the base station. Whereas another one of these pilot signals, transmitted at an increased pilot transmission power level for instance, may be for receipt and evaluation by other UEs served by the base station, such as UEs that are set to receive beamformed transmission of bearer traffic from the base station.

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.
