摘要： A method of implementing multiple radio access technologies, RATs, by a multi-RAT wireless communication network and a wireless communication apparatus. The multi-RAT wireless communication network transmits, to the wireless communication apparatus, a signal relating to a second RAT using a first RAT. The wireless communication apparatus uses a first radio communication module configured to support the first RAT to receive the signal, and activates a second radio communication module configured to support the second RAT from a power saving in order to perform a function. The first RAT generally has lower power consumption in use at the wireless communication apparatus than that of the second RAT.

摘要： A wireless communication method to provide mobility support of UEs (12) that are served by mobile relay base stations (14), by providing handover of a UE(12) for data traffic only between two mobile relay base stations. This is achieved by information exchanging between the source and target mobile relay stations of the concerned UE in handover, and/or the corresponding donor base stations (13, 11) if applicable. The handover is triggered by any of the following situations: (i) based on UE's measurement report, the signal quality of a neighbour cell is much better than the current serving cell; (ii) based on the measurement of the serving mobile relay base station, the signal quality of the link to the UE is worse than a certain threshold; or (iii) based on the measurement of the serving mobile relay base station, the signal quality of a neighbour cell (potential donor base station) is much better than the current donor base station.

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。

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： 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.
