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： 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 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： A radio bearer sharing scheme for wireless machine type communication (MTC), especially for a group of MTC devices with small traffic in the same cell. A group of MTC devices served in the same cell is treated as one user equipment. An MTC device ID is used to uniquely identify such an MTC device on the MTCu interface with a base station in a cell. All the MTC devices in a group share the same radio network identifier and the MTC group identifier, and can be distinguished by the device index in the group. The base station allocates one radio bearer over the MTCu interface for the small sessions of the devices, which have similar QoS requirements (QCI parameter and Layer 2 parameters) and the same MTC server. The data transmission scheduling information is signalled from the base station to the MTC devices in the same group, which may be achieved without over the air signalling if the timing of the UL signal is linked to a corresponding DL transmission interval. Then the devices transmit data packets one by one accordingly. Within the MTCu DRB, the compressed ID is added into the PDCP PDU header to identify the packets belonging to different MTC devices. Only updates need to be communicated between the MTC devices and the base station in the case that the device members of an MTC group change.
摘要翻译：一种用于无线机器类型通信（MTC）的无线承载共享方案，特别是用于在同一小区中具有小流量的一组MTC设备。在同一个小区中服务的一组MTC设备被视为一个用户设备。 MTC设备ID用于在与小区中的基站的MTCu接口上唯一地识别这样的MTC设备。组中的所有MTC设备共享相同的无线电网络标识符和MTC组标识符，并且可以通过组中的设备索引来区分。基站在MTCu接口上为具有类似QoS要求（QCI参数和二层参数）和相同MTC服务器的设备的小会话分配一个无线承载。数据传输调度信息从基站向相同组中的MTC设备发信号通知，如果UL信号的定时链接到对应的DL传输间隔，则可以通过空中信令实现数据传输调度信息。然后设备逐个传输数据包。在MTCu DRB中，将压缩的ID添加到PDCP PDU报头中，以识别属于不同MTC设备的分组。在MTC组的设备成员发生变化的情况下，只需要在MTC设备和基站之间传送更新。
