    • PROBLEM TO BE SOLVED: To provide techniques for sending control information, such as CQI information and ACK information, in a wireless communication system.SOLUTION: User equipment (UE) maps first information (e.g., CQI information) to M most significant bits (MSBs) of a message and maps second information (e.g., ACK information) to N least significant bits (LSBs) of the message if the second information is sent, where M≥1 and N≥1. The UE encodes the message with a block code, encodes the M MSBs with the first M basis sequences of the block code and encodes the N LSBs with the next N basis sequences of the block code. The second information includes N ACK bits. The UE sets each of the N ACK bits to a first value for an ACK or to a second value for a NACK. The second value is also used for DTX of ACK information.
    • 要解决的问题:提供在无线通信系统中发送诸如CQI信息和ACK信息的控制信息的技术。解决方案:用户设备(UE)将第一信息(例如,CQI信息)映射到M个最高有效位(MSB) ),并且如果发送第二信息则将第二信息(例如,ACK信息)映射到消息的N个最低有效位(LSB),其中M≥1且N≥1。 UE使用块码对消息进行编码,用块码的第一M个基本序列对M个MSB进行编码,并用块码的下一个N个基本序列对N个LSB进行编码。 第二信息包括N个ACK位。 UE将N个ACK位中的每一个设置为用于ACK的第一值或针对NACK设置第二值。 第二个值也用于ACK信息的DTX。
