    • A new measurement report and/or reporting trigger for an LTE-based wireless communication network, in order to identify the occurrence of interference which is non-uniform in the frequency domain The new report/trigger may be a modification of existing RSSI, RSRP and/or RSRQ to focus on specific sub-bands, sub-frames and/or sub-intervals of sub-frames within the available bandwidth and frame structure A UE in the network monitors a measurement object such as received signal strength for each of a plurality of cells (S10) to obtain measured values, computes a difference or ratio between two such measured values (S20) and once a trigger event has occurred (S30), which may be a novel trigger based on said difference/ratio, send a report (S40) to its serving station The report may indicate the computed difference/ratio and/or the measured values themselves

    • A procedure for inter-RAT cell selection by allowing a terminal such as an loT device, under longer term network control, to access a cell on another RAT. A multi-RAT cellular communication system comprises a first base station (20) providing a first cell (30) using a first RAT (RAT1), and a second base station (40) providing a second cell (50) using a second RAT (RAT2). A terminal (10) camped on the first cell (30) may perform a cell selection/reselection procedure to connect to the second cell (50). This is achieved by the first base station (20) transmitting a trigger condition control message including at least one parameter for deciding whether to trigger the cell selection/reselection procedure. Each such parameter is stored in an internal memory of the terminal (10). At some later time the terminal (10) decides whether to trigger the cell selection/reselection procedure by executing trigger condition checking algorithms, which combine the at least one parameter from the trigger condition control message with at least one property of the terminal not known in the network, such as the current battery level of the terminal. The second base station (40) completes the cell selection/reselection procedure with the terminal (10) and grants a connection to the second cell (50). This reduces the amount of signalling (and therefore terminal power) required for inter-RAT cell selection and re-selection.

    • A method for operating and controlling devices (12) connected to a network which allows the transmission of small data packets after reading System Information. The network can control a cell to allow access from devices (12) using an extended coverage mode, ECM, outside the normal coverage area of the cell. Initial access from devices in the extended cell coverage area can be scheduled (S104, S110) with the use of a pre-defined scheduled time for the devices to access the cell. A transmission of a schedule for ECM operation to the devices (12) that are using the ECM is provided (S144) after an ECM capable device has been moved from idle to connected mode for the first time, and can be updated (S146) at every scheduled opportunity when the device subsequently moves to connected mode. In addition, embodiments of the present invention provide a modified RACH procedure (S122, S128, S134, S140) to be followed by devices (12) taking advantage of the ECM.
    • 一种用于操作和控制连接到网络的设备(12)的方法,其允许在读取系统信息之后传输小数据分组。 网络可以控制小区以允许使用在小区的正常覆盖区域之外的扩展覆盖模式(ECM)的装置(12)进行访问。 可以通过使用预定义的预定时间来调度在扩展小区覆盖区域中的设备的初始接入(S104,S110),以便设备访问小区。 在ECM能力设备首次从空闲状态移动到连接模式之后,提供用于ECM操作的调度对正在使用ECM的设备(12)的传输(S144),并且可以被更新(S146) 当设备随后移动到连接模式时的每个预定机会。 此外,本发明的实施例提供了利用ECM的装置(12)将遵循的修改的RACH程序(S122,S128,S134,S140)。

    • A buffer status reporting scheme for a terminal (10) wishing to transmit data simultaneously in multiple RATs of a wireless communication network, which enables the co-ordination of multiple base stations (12, 14) of different RATs (e.g. LTE eNB, UMTS base station, WiFi access point, etc.) with the assistance of the terminal (10) in order to achieve efficient radio resource scheduling for multi-RAT multi-flow aggregation in uplink. A radio bearer is configured for multi-RAT multi-flow aggregation by the network, and multiple logical channel IDs are assigned to this RB that may be associated with different RATs. Logical channels associated with a certain RAT (or a given set of RATs) may be grouped into one logical channel group for radio resource scheduling reason. The terminal (10) performs buffer status reporting, according to the configuration, on all involved RATs and sends reports/indications to one or more involved base stations (12.14).
    • 一种用于希望在无线通信网络的多个RAT中同时发送数据的终端(10)的缓冲器状态报告方案,其使得能够协调不同RAT(例如LTE eNB,UMTS基站)的多个基站(12,14) 站点,WiFi接入点等),以便在上行链路中实现用于多RAT多流聚合的有效的无线电资源调度。 无线电载体被配置为由网络进行多RAT多流聚合,并且将多个逻辑信道ID分配给可以与不同RAT相关联的该RB。 与特定RAT(或给定的一组RAT)相关联的逻辑信道可以被分组为用于无线电资源调度原因的一个逻辑信道组。 终端(10)根据配置在所有涉及的RAT上执行缓冲器状态报告,并向一个或多个相关基站(12.14)发送报告/指示。
