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。
