example 1
[0098] Example 1 is the case of M=2, and the mapping relationship among feedback information, channel selection and modulation symbols of different downlink component carriers is shown in Table 1. In the following, the UE on the sending side selects an appropriate PUCCH channel and modulation symbol to send feedback information according to the mapping relationship, and the base station on the receiving side detects the actual feedback information according to the PUCCH channel and modulation symbol where the feedback information is located, including the following Several situations:
[0099] a1. The UE sends feedback information according to the mapping relationship. Specifically: when the feedback information of the two downlink component carriers is ACK and ACK respectively, according to the current mapping relationship, the second channel index corresponding to the channel selection On the corresponding PUCCH, the modulation symbol (1, 1) on the current PUCCH is used to ...
example 2
[0107] Example 2 is the case of M=3, and the mapping relationship among feedback information, channel selection and modulation symbols of different downlink component carriers is shown in Table 2. In the following, the UE on the sending side selects an appropriate PUCCH channel and modulation symbol to send feedback information according to the mapping relationship, and the base station on the receiving side detects the actual feedback information according to the PUCCH channel and modulation symbol where the feedback information is located, including the following Several situations:
[0108] b1. The UE sends feedback information according to the mapping relationship: when the feedback information of the three downlink component carriers is ACK, ACK and ACK respectively, according to the current mapping relationship, the third channel index corresponding to the channel selection On the corresponding PUCCH, the modulation symbol (1, 1) on the current PUCCH is used to send ACK...
