Abstract: The invention relates to a method for providing control signalling associated to a protocol data unit conveying user data in a mobile communication system and to the control channel signal. The invention also provides a mobile station and a base station and their respective operation in view of the newly defined control channel signals. To reduce the control channel overhead, the invention suggests defining a common field for the transport format and redundancy version in the control channel information format. According to one approach, the common field is used to jointly encode transport format and redundancy version therein. According to another aspect, one shared field is provided on the control channel signal that indicates either a transport format or a redundancy version depending of whether the control channel signal relates to an initial transmission or a retransmission. In another embodiment, further enhancements to a HARQ protocol are suggested for addressing certain error cases.

Abstract translation: 本发明涉及一种用于提供与在移动通信系统中传送用户数据的协议数据单元相关联的控制信令和控制信道信号的方法。 鉴于新定义的控制信道信号，本发明还提供了移动台和基站及其各自的操作。 为了减少控制信道开销，本发明建议在控制信道信息格式中定义传输格式和冗余版本的公共字段。 根据一种方法，公共字段用于联合编码其中的传输格式和冗余版本。 根据另一方面，根据控制信道信号是关于初始传输还是重传，在控制信道信号上提供指示传输格式或冗余版本的一个共享字段。 在另一个实施例中，建议对HARQ协议的进一步增强用于解决某些错误情况。
