Nested sequence indexing for uplink control information

A user equipment (UE) comprising:

• one or more processors;
• and
• one or more memories coupled with the one or more processors and storing processor-executable code that, when executed by the one or more processors, is configured to cause the UE to:
• encode a first sequence of k+1 bits of first uplink control information (UCI) using a sequence index that is in accordance with a value of a final (k+1)th bit of the first sequence of k+1 bits of the first UCI, the sequence index being:
• a first sequence index, that is associated with encoding a first k bits of the first sequence of k+1 bits of the first UCI, in accordance with the final (k+1)th bit of the UCI having a first value, or
• a second sequence index, that is not associated with encoding any sequence of k bits of UCI, in accordance with the final (k+1)th bit of the first UCI having a second value;
• and
• transmit, to a network node, the encoded UCI.

A non-transitory computer-readable medium having program code recorded thereon for wireless communication by a user equipment (UE), the program code executed by one or more processors and comprising:

• program code to encode a first sequence of k+1 bits of first uplink control information (UCI) using a sequence index that is in accordance with a value of a final (k+1)th bit of the first sequence of k+1 bits of the first UCI, the sequence index being:
• a first sequence index, that is associated with encoding a first k bits of the first sequence of k+1 bits of the first UCI, in accordance with the final (k+1)th bit of the UCI having a first value, or
• a second sequence index, that is not associated with encoding any sequence of k bits of UCI, in accordance with the final (k+1)th bit of the first UCI having a second value;
• and
• program code to transmit, to a network node, the encoded UCI.
