看Spec吧，最新的里面应该有7种，应该还在不断更新

这些答案不是唯一的，随着版本的演进，UCI和DCI都在不断的增加，以PUCCH,UCI来说
R8/R9是相同的
R8/R9：
- Format 1a for 1-bit HARQ-ACK or in case of FDD for 1-bit HARQ-ACK with positive SR
- Format 1b for 2-bit HARQ-ACK or for 2-bit HARQ-ACK with positive SR
- Format 1b for HARQ-ACK with channel selection
- Format 1 for positive SR
- Format 2 for a CQI/PMI or a RI report when not multiplexed with HARQ-ACK
- Format 2a for a CQI/PMI or a RI report multiplexed with 1-bit HARQ-ACK for normal cyclic prefix
- Format 2b for a CQI/PMI or a RI report multiplexed with 2-bit HARQ-ACK for normal cyclic prefix
- Format 2 for a CQI/PMI or a RI report multiplexed with HARQ-ACK for extended cyclic prefix

R10/R11
- Format 1a for 1-bit HARQ-ACK or in case of FDD for 1-bit HARQ-ACK with positive SR
- Format 1b for 2-bit HARQ-ACK or for 2-bit HARQ-ACK with positive SR
- Format 1b for up to 4-bit HARQ-ACK with channel selection when the UE is configured with more than one
serving cell or, in the case of TDD, when the UE is configured with a single serving cell
- Format 1 for positive SR
- Format 2 for a CSI report when not multiplexed with HARQ-ACK
- Format 2a for a CSI report multiplexed with 1-bit HARQ-ACK for normal cyclic prefix
- Format 2b for a CSI report multiplexed with 2-bit HARQ-ACK for normal cyclic prefix
- Format 2 for a CSI report multiplexed with HARQ-ACK for extended cyclic prefix
- Format 3 for up to 10-bit HARQ-ACK for FDD and for up to 20-bit HARQ-ACK for TDD

另外，DCI也有类似的现象
