Abstract: A wireless access network includes a first access point having a first coverage area, and a second access point having a second coverage area. A portion of the second coverage area overlaps with the first coverage area in an overlapping region. The network further includes a central controller in operable communication with the first and second access points, and a single station device located within the overlapping region. The single station device is configured to connect with the first and second access points. The central controller is configured to (i) control downlink data transmission from the first and second access points, and (ii) implement a scheduling protocol for the downlink data transmission, such that the single station device receives at least a first portion of the downlink data transmission from the first access point and a second portion of the downlink data transmission from the second access point.

Abstract: Systems and methods for performing handovers for a user equipment (UE) include storing a dynamically-triggered search timer value and a high priority public land mobility network (PLMN) identifier at the UE (e.g., using a universal subscriber identity module (USIM). The UE generates a periodic measurement report with a list of PLMN identifiers associated with nearby access network nodes. In response to entering idle mode, the UE 102 determines whether the list of PLMN identifiers includes the high priority PLMN. In response to the list of PLMN identifiers including the high priority PLMN, the UE 102 initiates a dynamically-triggered search for a handover at a time indicated by the dynamically-triggered search timer value rather than by a larger minimum periodic search timer value. Accordingly, the dynamically-triggered search occurs quickly (e.g., between 5 and 30 seconds) after the UE enters the idle mode as compared to minimum periodic search timer-based handover searches.

Abstract: Systems and methods include an access layer to perform handovers for a User Equipment (UE) using a mobility status of the UE. A source access node (e.g., a femto cell, small cell, or a macro cell) establishes a first network connection with the UE. Based on a mobility status of the UE, the source access node selects either a small cell access node or a macro cell access node as a target node for connecting to the UE with a handover (e.g., by establishing a second network connection with the UE). The UE may have a medium mobility status or a high mobility status and, in response, be connected to the macro cell access cell for continuous connectivity. Alternatively, the UE may have the low mobility status and, in response, a signal strength analysis of the access nodes may be performed to select the target node for the handover.
