Abstract: Disclosed is a method and system for reducing the load on a downlink control channel of a given carrier of a plurality of carriers in a coverage area. As disclosed, a base station may determine that the downlink control channel of the given carrier is threshold loaded. In response to this determination, the base station may then (a) identify a particular subset of the UEs that are currently designated for DCI transmission on the downlink control channel of the given carrier and then (b) take action to de-designate the identified subset of UEs for DCI transmission on the given carrier and instead designate the identified subset of UEs for DCI transmission only on one or more other carriers in the coverage area.

Abstract: Disclosed is a method and system for dynamically managing carrier aggregation based on operating conditions of small cells in a wireless communication system. A first base station may be configured for providing wireless services on a first wireless carrier band and a second wireless carrier band. One or more additional base stations may each configured for providing wireless services on the second wireless carrier band. A determination can be made that a load on the one or more additional base stations exceeds a threshold level while each is providing wireless coverage within a region that at least partially overlaps with wireless coverage provided by the first base station. In response, the first base can be caused to refrain from aggregating the first and second wireless carrier bands for providing wireless services under operational conditions defined to cause the base station to aggregate the first and second wireless carrier bands.

Abstract: A representation of a series of hybrid automatic repeat request (HARQ) acknowledgments may be obtained. Each HARQ acknowledgment in the series may have either positively or negatively acknowledged one or more HARQ subpackets that were consecutively transmitted from the RAN to a WCD. Based on at least the representation of the series of HARQ acknowledgments, an amount of HARQ subpackets to consecutively transmit to the WCD may be determined. The RAN may consecutively transmit the amount of HARQ subpackets to the WCD.

Abstract: Disclosed is a method and system for balancing control channel resource allocations between base stations. As disclosed, a first base station provides a first downlink control channel including a first set of air interface resources and a second base station provides a second downlink control channel including a second set of air interface resources, the first set of air interface resources and the second set of air interface resources being mutually exclusive. Upon detecting a threshold difference between (i) an extent of a capacity of the first downlink control channel being unused and (ii) an extent of a capacity of the second downlink control channel being unused, the system may change allocation resources between downlink control channels such that (i) capacity of one of the first and second downlink control channels is increased and (ii) capacity of the other one of the first and second downlink control channels is decreased.

Abstract: A method and system to help manage wireless communication with a UE in a manner that takes into account a predicted impact of data bundling, such as TTI bundling, with respect to communication of data during a session. When a radio access network (RAN) is going to serve a UE with data communication for a VoLTE call or other session that would trigger such bundling, the RAN will predict the extent of other data that will be communicated during the session, and the RAN will predict the impact, such as increased air interface load, that would result from data bundling of at least that other data communication. If the RAN thereby predicts that the impact of data bundling with respect to at least that other data communication will exceed a predefined threshold level, then the RAN will responsively take action to limit its air interface communication with the UE.
