    Abstract: A method to dynamically configure a base station based on evaluation of whether nearby and/or neighboring base stations operate on a preferred coverage frequency. For instance, the base station could be configured to broadcast as a start-scanning threshold value a relatively high value in response to determining that a base station operating on the preferred coverage frequency is located within a predefined threshold distance. Further, the base station could be configured to broadcast as the start-scanning threshold value an intermediate value in response to determining that no nearby base station operates on the preferred coverage frequency but at least one base station that is a handover neighbor operates on the preferred coverage frequency. And the base station could be configured to broadcast as the start-scanning threshold value a relatively low value in response to determining that no nearby base stations or handover neighbors operate on the preferred coverage frequency.

    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.
