    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.

    Abstract: Disclosed is a method and system for controlling air interface communication in a wireless communication system that supports multiple TDD configurations. In a disclosed example, a base station's cell is initially configured to operate with a particular TDD configuration. The base station then detects a trigger to reduce uplink latency in the cell, such as by detecting a threshold number of devices being served with latency-sensitive communication such as voice-over-packet communication. And the base station responsively reconfigures the cell to operate with a different TDD configuration having lower uplink latency, where uplink latency of each TDD configuration is based average wait to uplink subframe of the TDD configuration.

    Abstract: A method and system for managing capacity of a base station's air interface. The base station identifies a served user equipment device (UE) based at least in part on the UE being located in an area of overlap between coverage of the base station and coverage of another base station. The base station then increases an order of modulation of air interface communication between the base station and the identified UE, so as to help free up some air interface capacity. Further, in view of the possible decrease in reliability of communication due to the increased order of modulation, the base station may also invoke use of Coordinated Multipoint Communication (CoMP) for the UE to help improve air interface communication between the base station and the UE.

    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: Coordinated multipoint (CoMP) may involve coordination between multiple sectors to receive and/or process a given user equipment's uplink signal. Embodiments herein may help to intelligently select the particular sectors that should coordinate to provide uplink CoMP, based on the types of applications being served in sectors that are candidates to provide uplink CoMP. For example, a base station serving a primary sector in an CoMP group that includes two or more candidates from which to select a secondary sector sectors for uplink CoMP, may evaluate the application being served by traffic flows in these candidates, in an effort to select secondary sectors having lower-priority traffic flows.
