    Abstract: Disclosed is a method for a femtocell to reduce interference with an overlapping macrocell. The femtocell determines soft-frequency-reuse (“SFR”) information of the macrocell. From that information, the femtocell determines which frequency sub-channels are assigned by the macrocell for its cell-center users and which frequency sub-channels are assigned for cell-edge users. (Cell-edge users are given a higher transmission power profile in order to overcome potential interference with neighboring macrocells.) Then, the femtocell selects from the cell-center user frequency sub-channels for transmission to the femtocell's users. By transmitting on the cell-center user frequency sub-channels, the femtocell reduces interference with the overlapping macrocell. The femtocell continues to update its knowledge of the macrocell's SFR information and re-assigns frequency sub-channels as the SFR changes. If the macrocell detects that one of its cell-center users is “close enough” to the femtocell, then the macrocell re-assigns the cell-center user as a cell-edge user to overcome interference.

    Abstract: A communications system provides a robust and fast inter-base station handoff mechanism, e.g. for networks using Enhanced Base Stations (EBS) equipment. A method for connecting a mobile device to a destination base station in the wireless communications system, may include steps of receiving a mobile device measurement report, transferring context information from a serving base station to possible target base stations, and receiving admission control information from possible target base stations. A priority list of the possible target base stations is calculated and sent to the mobile device. The mobile device connects to one or more of possible target base stations according to the priority list. The method may also entail receiving a release message from one of the possible target base stations to which the mobile device has successfully established a wireless connection, to allow release of resources of the prior serving base station.

    Abstract: A device classifies access or control channel signals into a first class or a second class, initializes a dormancy timer associated with the device, and sets the dormancy timer to a default value. The device also sets a signal target utilization threshold, receives actual signals via the access or control channel, and identifies, when a number of the actual signals exceeds the signal target utilization threshold, a particular signal, from the actual signals, as belonging to the first class or the second class. The device further increases the default value of the dormancy timer when the particular signal belongs to the first class, and decreases the default value of the dormancy timer when the particular signal belongs to the second class.

    Abstract: One or more devices determine uplink signal strength for a machine-to-machine (M2M) device using a wireless access network. The one or more devices identify a default uplink transmission mode that requires the M2M device to employ transmission time interval (TTI) bundling, when the uplink signal strength is below a particular threshold, and identify a default uplink transmission mode that requires the M2M device to not employ TTI bundling, when the uplink signal strength is not below the particular threshold. The one or more devices store, in a memory, the default transmission mode for the M2M device. The one or more devices retrieve, from the memory and during a wake-up time window associated with the M2M device, the default transmission mode for the M2M device and construct, for the M2M device, an uplink scheduling grant based on the stored default transmission mode.
