Question: In DCI format 2_2 for TPC commands with TPC-PUSCH-RNTI, what determines whether each block is assumed to be 2 bits or 3 bits by the UE?
Option 1: The presence of a CRC scrambled by TPC-PUSCH-RNTI
Option 2: The configuration of higher layer parameter `twoPUSCH-PC-AdjustmentStates`
Option 3: The payload size of format 1_0 in the common search space
Option 4: The number of information bits in the DCI format 2_2
Explanation: According to the specifications, for DCI format 2_2 with TPC-PUSCH-RNTI, if the UE is configured with the higher layer parameter `twoPUSCH-PC-AdjustmentStates`, it assumes each block is of 3 bits; otherwise, it assumes each block is of 2 bits. This directly ties the assumption of block size to the configuration of this specific higher layer parameter.
