UE对下行双码字进行HARQ确认时，是对两个码字一起确认，还是可以分开单独确认？
我看PUCCH format 1b 有2个bit，是不是就是用于对双码字进行确认的？

对。另外，2bit确实就是两个码字的ACK反馈
5.2.3.1 Channel coding for UCI HARQ-ACK
The HARQ-ACK bits are received from higher layers. HARQ-ACK consists of 1-bit of information, i.e., or 2-bits of information, i.e., with corresponding to HARQ-ACK bit for codeword 0 and corresponding to that for codeword 1. Each positive acknowledgement (ACK) is encoded as a binary ‘1’ and each negative acknowledgement (NACK) is encoded as a binary ‘0’. The HARQ-ACK bits are processed according to [2].
