摘要： In an LTE-based wireless communication system, each channel such as a control channel PDCCH is transmitted to the UE from one serving cell (the primary cell or Pcell). At the cell border the Pcell suffers from increased interference from neighbouring cells and typically a lower effective transmission rate is used to increase robustness to interference, for both data and control channel. Also, neighbouring cells are typically given different cell IDs, which can be used as a basis for distinguishing transmissions from different cells, even if radio frames are time-aligned. The invention modifies the control channel operation by arranging a common mapping of transmitted symbols to control channel resources in two different cells so that the same control channel message (P) or part of the message can be transmitted jointly from the two cells ((a),(b)), avoiding resources used in the cells for respective reference signals (R). This can be used to improve control channel reception at the cell border, without using more control channel resources. This would be beneficial in both normal system operation and also for Co-operative Multi-Point (CoMP) operation, e.g. using joint transmission techniques for data.
摘要翻译：在基于LTE的无线通信系统中，诸如控制信道PDCCH的每个信道从一个服务小区（主小区或Pcell）被发送到UE。在小区边界，Pcell遭受来自相邻小区的增加的干扰，并且通常使用较低的有效传输速率来增加数据和控制信道对干扰的鲁棒性。此外，相邻小区通常被给予不同的小区ID，其可以用作区分来自不同小区的传输的基础，即使无线电帧是时间对准的。本发明通过将传输符号的公共映射布置在两个不同的小区中的控制信道资源上来修改控制信道操作，使得相同的控制信道消息（P）或消息的一部分可以从两个小区（（a），（b）），避免在各个参考信号（R）的单元中使用的资源。这可以用于改善小区边界处的控制信道接收，而不需要更多的控制信道资源。这在正常的系统操作以及合作多点（CoMP）操作中都是有益的。使用联合传输技术进行数据传输。

摘要： 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).

摘要： A method for activation of a wireless communications link between a terminal (UE) and a first base station (SCeNB) under control of a second base station (MeNB), the method comprising: the second base station (MeNB) sending a first activation request signal to the terminal (UE); and the terminal (UE), in response to the first activation request signal, sending a second activation request signal to the first base station (SCeNB). The terminal therefore acts as proxy for communicating an activation request from the second base station to the first base station. This is useful in Small Cell scenarios where backhaul latency may delay an activation request over the X2 interface between the base stations.
摘要翻译：一种用于在第二基站（MeNB）的控制下激活终端（UE）和第一基站（SCeNB）之间的无线通信链路的方法，所述方法包括：所述第二基站（MeNB）发送第一激活请求信号到终端（UE）; 和所述终端（UE）响应于所述第一激活请求信号向所述第一基站（SCeNB）发送第二激活请求信号。因此，终端充当用于将激活请求从第二基站传送到第一基站的代理。这在小型小区场景中很有用，其中回程延迟可能会延迟通过基站之间的X2接口的激活请求。

摘要： The invention provides for association of data streams (and/or logical channels) with individual carriers (cells), and independent buffer status reporting per carrier for terminals with more than one uplink carrier configured. In a "Small Cell" scenario for 3GPP LTE, a terminal may be simultaneously served by a macro cell and one or more small cells. These may operate at different frequencies, have different traffic loading and support different QoS (Quality of Service). The invention allows independent control of traffic on the uplinks to the macro cell and the small cells, which can be used to optimize the user experience in relation to the available resources at any given time/location, and allows particular data to be routed via particular cells.
摘要翻译：本发明提供数据流（和/或逻辑信道）与各个载波（小区）的关联，以及针对具有多于一个上行链路载波的终端配置的每个载波的独立缓冲器状态报告。在3GPP LTE的“小小区”场景中，终端可以由宏小区和一个或多个小小区同时服务。这些可以在不同频率下操作，具有不同的流量负载并且支持不同的QoS（服务质量）。本发明允许对上行链路上的宏小区和小小区的业务的独立控制，其可以用于在任何给定时间/位置处优化与可用资源相关的用户体验，并且允许特定数据经由特定的路由被路由细胞。

摘要： The application relates to efficiently support handover in inter- eNB CoMP or other co-operating cell operation, particularly in heterogeneous network scenarios. The invention is based on the recognition that the information available in CoMP operations would be useful for handover management. An example of such information is CSI reports (Rl, PMI, CQI) of individual UEs. According to the proposed procedure, The serving eNB (11a) of a UE shares information with several candidate target eNBs (11 b, 11 c) for load balancing purposes, for example a suggested CSI-RS configuration, so that a common CSI-RS pattern/configuration can be agreed among the co-operating neighbour eNBs. CSI reports of all the candidate cells from several UEs in a given area may be shared. Handover requests are sent to the target eNBs so that the target eNBs can choose to admit the suitable UEs. Responses are compared by the serving eNB (11 a) or by a central control entity to make a final handover decision.
摘要翻译：该应用涉及有效地支持eNB间的CoMP或其他协作小区操作中的切换，特别是在异构网络场景中。本发明基于认识到在CoMP操作中可用的信息对于切换管理将是有用的。这样的信息的示例是各个UE的CSI报告（R1，PMI，CQI）。根据提出的过程，UE的服务eNB（11a）与多个候选目标eNB（11b，11c）共享信息，用于负载平衡目的，例如建议的CSI-RS配置，使得公共CSI-RS 模式/配置可以在协作邻居eNB之间达成一致。可以共享来自给定区域中的几个UE的所有候选小区的CSI报告。切换请求被发送到目标eNB，使得目标eNB可以选择允许合适的UE。响应由服务eNB（11a）或中央控制实体进行比较以进行最终切换决定。

摘要： A scheme to allow the random access process (for example) in an LTE UE to transmit more useful information earlier in the procedure. This may be achieved by transmitting two linked signals, which could be two simultaneously transmitted PRACH signatures. The additional information (such as UE identity or buffer status) is indicated by the choice of the second signal/signature, and/or by some combination of transmission characteristics of the linked signals. This allows an LTE network to reach a state of transmitting and/or receiving higher data rates more quickly than the current RACH procedure, thus reducing latency and improving the user experience. This is achieved without requiring significant additional complexity in the network.
摘要翻译：允许LTE UE中的随机接入过程（例如）在过程中更早地传送更有用信息的方案。这可以通过发送两个链接信号来实现，其可以是两个同时发送的PRACH签名。附加信息（例如UE身份或缓冲器状态）由第二信号/签名的选择和/或通过链接信号的传输特性的某种组合来指示。这允许LTE网络比当前的RACH过程更快地达到发送和/或接收更高数据速率的状态，从而减少等待时间并改善用户体验。实现这一点，而不需要在网络中显着的额外的复杂性。
