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: 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.

Abstract: In one aspect, the present invention provides methods (400, 900) and apparatuses (22, 26, 40)for detecting that a wireless communication device (40) in a serving cell (24, 27) is experiencing excessive interference variance (68), detecting a transmission pattern (74) of interfering transmissions (46) giving rise to such variance, and correspondingly adjusting scheduling of the device (40) as a function of the detected transmission pattern (74), to at least partly avoid the interfering transmissions (46). An advantageous feature of such operation is that the determination of excessive interference variance (68) and the determination of the transmission pattern (74) associated with that varying interference can be done by a network node (22, 26), e.g., the device's serving base station (22, 26), or by the device (40), without requiring backhaul signaling or other inter-node cooperation in the network (20).
