    Abstract: Systems and methods are disclosed for controlling cell selection between a high power base station and a neighboring low power base station in a cellular network. In one embodiment, a primary direction of traffic flow for a user equipment located within a transition zone between a high power base station cell of the high power base station and a low power base station cell of the low power base station is determined to be either an uplink direction or a downlink direction. Cell selection for the user equipment is then controlled based on the primary direction of traffic flow for the user equipment such that selection of the high power base station cell is favored if the primary direction of traffic flow is the downlink direction and selection of the low power base station cell is favored if the primary direction of traffic flow is the uplink direction.

    Abstract: Systems and methods for providing efficient utilization of spectrum in a cellular communication network that applies Almost Blank Subframes (ABSs) are disclosed. In general, the network includes an access node that applies ABSs in the downlink. In one embodiment, the access node identifies UEs for which transmissions are to be scheduled for the uplink using a scheduling scheme that does not require control information for every subframe. The access node then time-aligns scheduling instants of the UEs and subframes in the uplink that correspond to at least some of the ABSs in the downlink. In another embodiment, the access node identifies UEs for which transmissions are to be scheduled for the downlink using a scheduling scheme that does not require control information for every subframe. The access node then time-aligns scheduling instants of the UEs for the downlink and at least a subset of the ABSs in the downlink.

    Abstract: In a cellular communication network, a method of dynamic mobility management in which a base station employing cell-breathing or other similar energy-efficiency mechanism notifies User Equipments (UEs) in its cell, either via broadcasting or with direct over-the-air signaling, that such a mechanism is utilized within the cell. The base station may also notify neighbor base stations of its use of cell-breathing. The neighbor base stations disseminate this information to UEs within their own cells, and consider this information when deciding whether to hand over a UE to a base station that is capable of performing cell-breathing. The base station may also inform UEs in the cell and/or neighbor base stations when it is preparing to reduce transmission power. UEs store information regarding which base stations use cell-breathing, and consider this information when performing cell reselections.

    Abstract: The present invention relates to methods and devices for mobility management in a cellular communications system. A user equipment maintains (21) at least two sets of mobility trigger parameters. Each set of mobility trigger parameters corresponds to a predetermined user equipment speed range. The user equipment determines (22) a speed range that the speed of the user equipment falls into and selects (23), based on the determined speed range, at least one set of mobility trigger parameters to be used for performing mobility-based decisions. If the user equipment is in connected mode a network base station may select a set of mobility trigger parameters to be used for performing handover decisions based on a determined speed range of the user equipment. Advantages are that ping-pong mobility decisions may be avoided and it is sufficient to determine a range for the UE speed, which is less complicated than determining an accurate speed of the UE particularly in idle mode.

    Abstract: A method and a network node (110) for determining an indication of interference mitigation in a receiver comprised in a user equipment (120) are provided. The network node (110) receives, from the user equipment (120), a first set of measures and a second set of measures. The first set of measures relates to a signal received by the user equipment (120) and the second set of measures relates to the same signal. The first set of measures was obtained by the user equipment (120) prior to processing of the signal in the receiver, and the second set of measures was obtained by the user equipment (120) after processing of the signal in the receiver. Next, the network node (110) determines (202) the indication of interference mitigation based on the first and second sets of measures.
