摘要： Mobility parameters, such as those used in handoff decisions, are based on the speed of User Equipment (UE) (10), measured at two points. UE speed estimates are taken at both the UE (10) and base station (12), and the two speeds compared. If the speeds match (or differ by less than a predetermined amount), one or more mobility parameters are adapted based on the UE speed. These parameters may include time to trigger (TTT), time to satisfy (TTS), measurement time, forgetting factor, β, measurement period (Tm), handover prohibit timer, MeasurementReportingmargin, HOmargin, hysteresis, and the like. The UE speed comparison may be performed at the UE (10) or at the base station (12). In one embodiment, a plurality of UE speed ranges are defined (e.g., low, medium, high), with corresponding mobility parameter values associated with each range.
摘要翻译：移动性参数，如用于切换决策的参数，是基于在两点测量的用户设备（UE）（10）的速度。在UE（10）和基站（12）两者都进行UE速度估计，并且比较两个速度。如果速度匹配（或差别小于预定量），则基于UE速度来适配一个或多个移动性参数。这些参数可以包括触发时间（TTT），满足时间（TTS），测量时间，遗忘因子，测量周期（Tm），切换禁止定时器，测量报告率，停留时间，滞后等。 UE速度比较可以在UE（10）处或在基站（12）处执行。在一个实施例中，多个UE速度范围被定义（例如，低，中等，高），具有与每个范围相关联的对应的移动性参数值。

摘要： 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).

摘要： 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.

摘要： The present invention relates to a method and an arrangement (102, 104, 106, 202, 302, 304, 502, 504, 702, 704, 1000, 1014) for prioritizing one of multiple cell-related mobility decisions associated with multiple parallel mobility events being triggered, comprising recognizing parameter settings associated with at least two parallel mobility events being triggered (steps 406, 604; 806), evaluating the parameter settings for determining which cell-related mobility decision to prioritize (steps 408; 606; 808), and performing a task according to the cell-related prioritized mobility decision (steps 410, 608; 814), to achieve a cell re-selection in idle mode or a hand over in connected mode. By applying multiple parameter settings a better performance is achieved as can be seen by a reduced percentage of time a User Equipment (102, 202, 302, 502, 702, 1000) is not connected to the best cell.

摘要： The method according to the present invention provides synchronization in a heterogeneous mobile network, for the purpose of interoperability, of a wireless local area network, in which a medium is reserved for a certain service or user in radio channel reservation periods (702) of variable duration, to a radio access network, transmitting data in transmission time intervals of pre-defined duration (603).

摘要： 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.

摘要： 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.

摘要： 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.
