4.7.3B Channel coding for HS-DPCCH when Secondary_Cell_Enabled is at least 3 or when the UE is configured in MIMO mode in at least one cell and Secondary_Cell_Enabled is greater than 0
25.2123GPPMultiplexing and channel coding (FDD)Release 17TS
Two forms of channel coding are used, one for the composite precoding control indication (PCI) and channel quality indication (CQI) and another for the composite HARQ-ACK (acknowledgement).
4.7.3B.1 Channel coding for the composite HS-DPCCH HARQ-ACK
The composite HARQ acknowledgement message to be transmitted, as defined in [4], shall be coded to 10 bits as shown in Table 15C.2. The feedback related to the first cell is given before the divider sign and the feedback related to the second cell is given after the divider sign. ”A’ means ”ACK’, ”N’ means ”NACK’ and ”D’ means ”no transmission’ (”DTX’). ”AA’, ”AN’, ”NA’ and ”NN’ refer to feedback for dual-stream transmission in a cell. For example, ”AN’ means ACK on the primary stream and NACK on the secondary stream. The output is denoted w0, w1,…w9.
When Secondary_Cell_Enabled is 2, and when Secondary_Cell_Active is 2, HARQ-ACK information for the 2nd secondary serving HS-DSCH cell is jointly encoded with a DTX message in place of the 3rd secondary serving HS-DSCH cell.
When Secondary_Cell_Enabled is 4, and when Secondary_Cell_Active is 4, HARQ-ACK information for the 4th secondary serving HS-DSCH cell is jointly encoded with a DTX message in place of the 5th secondary serving HS-DSCH cell.
When Secondary_Cell_Enabled is 6, and when Secondary_Cell_Active is 6, HARQ-ACK information for the 6th secondary serving HS-DSCH cell is jointly encoded with a DTX message in place of the 7th secondary serving HS-DSCH cell.

When Secondary_Cell_Active is 2 or 3, and when DTX message is indicated for a cell pair, whose HARQ-ACK information is jointly encoded, the specific DTX code word as defined in Table 15C.2A is transmitted for that cell pair except for the case when DTX message is indicated for all active cells, in which case the HARQ-ACK slot is DTXed. The slot containing HARQ-ACK information is either transmitted or DTXed. If Secondary_Cell_Active is larger than 3 and when DTX message is indicated for both cell pairs transmitted on one of the two HS-DPCCHs and there is at least one HARQ-ACK message associated with the other HS-DPCCH that does not correspond to DTX message, then the specific DTX code word as defined in Table 15C.2A is transmitted for all cell pairs for which a DTX message is indicated. If the DTX message is indicated for all active cell pairs then the slot on each respective HS-DPCCH containing the HARQ-ACK information is DTXed.
