6.3.1 Uplink control information on PUCCH
38.2123GPPMultiplexing and channel codingNRRelease 17TS
The procedure in this clause applies to PUCCH formats 2/3/4.
The following clauses 6.3.1.2, 6.3.1.3 and 6.3.1.5 apply regardless of whether the higher layer parameter uci-MuxWithDiffPrio is configured or not. The following clauses 6.3.1.1, 6.3.1.4 and 6.3.1.6 apply by assuming uci-MuxWithDiffPrio is not configured, or uci-MuxWithDiffPrio is configured and the UCIs for transmission on a PUCCH are of the same priority index, unless stated otherwise.
If the UE is configured with a PUCCH-SCell, uci-MuxWithDiffPrio is replaced by uci-MuxWithDiffPrioSecondaryPUCCHgroup for the secondary PUCCH group in this clause.
6.3.1.1 UCI bit sequence generation
6.3.1.1.1 HARQ-ACK/SR only
If only HARQ-ACK bits are transmitted on a PUCCH, the UCI bit sequence is determined by setting for and , where the HARQ-ACK bit sequence is given by Clause 9.1 of [5, TS38.213].
If only HARQ-ACK and SR bits are transmitted on a PUCCH, the UCI bit sequence is determined by setting for , for , and , where the HARQ-ACK bit sequence is given by Clause 9.1 of [5, TS 38.213], and the SR bit sequence is given by Clause 9.2.5.1 of [5, TS 38.213].
6.3.1.1.2 CSI only
If cqi-BitsPerSubband is configured, this Clause 6.3.1.1.2 applies by taking Subband CQI as Subband differential CQI and replacing the corresponding number of bits 2 by 4.
The bitwidth for PMI of codebookType=typeI-SinglePanel with 2 CSI-RS ports is 2 for Rank=1 and 1 for Rank=2, according to Clause 5.2.2.2.1 in [6, TS 38.214].
The bitwidth for PMI of codebookType=typeI-SinglePanel with more than 2 CSI-RS ports is provided in Tables 6.3.1.1.2-1, where the values of and are given by Clause 5.2.2.2.1 in [6, TS 38.214].
