    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.

    Abstract translation: 一种帮助管理与UE的无线通信的方法和系统，其考虑到在会话期间关于数据通信的数据捆绑（例如TTI绑定）的预测影响的方式。 当无线电接入网络（RAN）将为具有用于VoLTE呼叫的数据通信或将触发这种捆绑的其他会话的UE服务时，RAN将预测在会话期间将被传送的其他数据的范围，并且RAN 将预测由至少其他数据通信的数据捆绑导致的影响，如增加空中接口负载。 如果RAN因此预测到关于至少该其他数据通信的数据绑定的影响将超过预定义的阈值水平，则RAN将响应地采取行动来限制其与UE的空中接口通信。

    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 controlling TTI bundling in a wireless communication system that includes a base station configured to serve UEs over an air interface, where each UE has a maximum transmit power for air interface transmission, where the UEs include a first class of UEs and a second class of UEs, and where the maximum transmit power of the UEs of the second class is higher than the maximum transmit power of the UEs of the first class. The base station detects a capacity constraint on the air interface, such a threshold high air interface load, and the base station responds by operating in a mode in which the base station differentially controls application of TTI bundling as between the first class of UEs and the second class of UEs, based on the second class of UEs having higher maximum transmit power than the first class of UEs.

    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.
