Abstract: A method may provide wireless communications in a network including a first base station and a second base station, with the first base station operating within a coverage area of the second base station. The method may include providing soft-cell communications in an extended range area of the first base station, with the extended range area being outside a primary range area of the first base station. A number of wireless devices in the extended range area connected and/or communicating with the first base station may be tracked. Responsive to the number of wireless devices in the extended range area connected and/or communicating with the first base station exceeding a threshold (Threshold_N), the extended range area over which soft-cell communications are provided may be reduced.

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 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).

Abstract: A base station node (BS) of a heterogeneous radio access network comprises a terminal locator (34) and a scheduler (36). The terminal locator (34) obtains an indication of location of a wireless terminal (30) in a cell served by the base station (BS), e.g., whether the wireless terminal (30) is in a center region (M) or an edge region (E) for the cell served by the base station node (BS). The scheduler (36) uses the indication of location to assign to the wireless terminal (30) a frequency of a frequency bandwidth usable by the heterogeneous radio access network. The scheduler (36) assigns a frequency from a partitioned portion of the frequency bandwidth if the cell served by the base station node is a micro cell and the wireless terminal is in an edge region of a micro cell. The scheduler (36) also assigns a frequency of the frequency bandwidth if the cell served by the base station node is a micro cell and the wireless terminal is in a center portion of the micro cell.

Abstract: A method of determining a transition of a terminal (110) between its idle state and its connected state is described. The connected state of the terminal (110) is associated with the terminal (110) being connected to a node (108) of a radio access network (104) of a communication network (100). The method comprises at least one of at least partly setting up, prior to a connection setup procedure for setting up a connection between the terminal (110) and the node (108) of the radio access network (104), a security configuration to be used between the terminal (110) and the node (108) of the radio access network (104) for communication, and at least partly setting up, prior to the connection setup procedure, a bearer configuration to be used between the terminal (110) and the node (108) of the radio access network (104) for communication. Thus, an efficient usage of network resources and/or energy resources of a terminal in association with a transition of a terminal between its idle state and its connected state may be enabled.
