摘要： According to the present invention, a receiving node of a telecommunications network (20) (e.g. a radio base station (22) in uplink, or a mobile terminal (24) in downlink) transmits a single acknowledgement message to a transmitting node (e.g. a mobile terminal (24) in uplink, or a radio base station (22) in downlink) in respect of signals received over a plurality of frequency-aggregated carriers (component carriers) (10) between the transmitting and receiving nodes. If all signals are decoded correctly in the receiving node, a positive acknowledgement message (ACK) is sent to the transmitting node; if not all signals are decoded correctly, a negative acknowledgement message (NACK) is sent, or no acknowledgement message is sent. In this way, a single acknowledgement message can be sent for signals received over multiple carriers. The acknowledgement message can have the same format as legacy standards (for example, as specified in Release 8 of the 3GPP specifications), providing compatibility with existing equipment. The number of messages is also reduced compared with the straightforward approach of transmitting individual acknowledgement messages per component carrier.

摘要翻译： 根据本发明，电信网络（20）（例如，上行链路中的无线电基站（22）或下行链路中的移动终端（24））的接收节点向发送节点（例如， 关于在发送节点和接收节点之间的多个频率聚合载波（分量载波）（10）上接收的信号，上行链路中的移动终端（24）或下行链路中的无线电基站（22）。 如果所有信号在接收节点中被正确地解码，则肯定确认消息（ACK）被发送到发送节点; 如果不是全部信号被正确地解码，则发送否定确认消息（NACK），或者不发送确认消息。 以这种方式，可以针对在多个载波上接收的信号发送单个确认消息。 确认消息可以具有与传统标准相同的格式（例如，如3GPP规范的版本8中所规定），提供与现有设备的兼容性。 与每个分量载波发送各个确认消息的简单方法相比，消息的数量也减少了。
