10.1.3 TDD HARQ-ACK feedback procedures
36.2133GPPEvolved Universal Terrestrial Radio Access (E-UTRA)Physical layer proceduresRelease 17TS
For TDD and a UE that does not support aggregating more than one serving cell with frame structure type 2, two HARQ-ACK feedback modes are supported by higher layer configuration.
- HARQ-ACK bundling and
- HARQ-ACK multiplexing
For TDD and a BL/CE UE, if multiple TBs are not scheduled by a single DCI,
– if the UE is configured with csi-NumRepetitionCE equal to 1 and mPDCCH-NumRepetition equal to 1,
– the UE may be configured with HARQ-ACK bundling or HARQ-ACK multiplexing;
– HARQ-ACK multiplexing can be configured only if pucch-NumRepetitionCE-format1 equal 1 and HARQ-ACK multiplexing is performed according to the set of Tables 10.1.3-5/6/7
– else
– the UE is not expected to receive more than one PDSCH transmission, or more than one of PDSCH and MPDCCH indicating downlink SPS releases, with transmission ending within subframe(s) , where 
and 
is defined in Table 10.1.3.1-1 intended for the UE;
For TDD UL/DL configuration 5 and a UE that does not support aggregating more than one serving cell with frame structure type 2 and the UE is not configured with EIMTA-MainConfigServCell-r12 for the serving cell, only HARQ-ACK bundling is supported.
A UE that supports aggregating more than one serving cell with frame structure type 2 is configured by higher layers to use either PUCCH format 1b with channel selection or PUCCH format 3/4/5 for transmission of HARQ-ACK corresponding to subframe-PDSCH when configured with more than one serving cell with frame structure type 2.
For subframe-PUCCH and a UE that supports aggregating more than one serving cell with frame structure type 2 and is not configured with the parameter EIMTA-MainConfigServCell-r12 for any serving cell is configured by higher layers to use HARQ-ACK bundling, PUCCH format 1b with channel selection according to the set of Tables 10.1.3-2/3/4 or according to the set of Tables 10.1.3-5/6/7, or PUCCH format 3 for transmission of HARQ-ACK when configured with one serving cell with frame structure type 2.
For subframe-PUCCH and a UE that is configured with the parameter EIMTA-MainConfigServCell-r12 and configured with one serving cell is configured by higher layers to use PUCCH format 1b with channel selection according to the set of Tables 10.1.3-5/6/7, or PUCCH format 3 for transmission of HARQ-ACK. A UE that is configured with the parameter EIMTA-MainConfigServCell-r12 for at least one serving cell and configured with more than one serving cell is configured by higher layers to use PUCCH format 1b with channel selection according to the set of Tables 10.1.3-5/6/7, or PUCCH format 3/4/5 for transmission of HARQ-ACK.
PUCCH format 1b with channel selection according to the set of Tables 10.1.3-2/3/4 or according to the set of Tables 10.1.3-5/6/7 is not supported for TDD UL/DL configuration 5.
TDD HARQ-ACK bundling is performed per codeword across 
multiple subframes/slots in downlink or special subframes associated with a single UL subframe/slot n, where 
is the number of elements in the set 
defined in Table 10.1.3.1-1C if the UE is configured with higher layer parameter shortTTI for slot-PDSCH, in Table 10.1.3.1-1B if the UE is configured with higher layer parameter shortProcessingTime and the corresponding PDCCH with CRC scrambled by C-RNTI is in the UE-specific search space for subframe-PDSCH and in Table 10.1.3.1-1 otherwise, by a logical AND operation of all the individual PDSCH transmission (with and without corresponding PDCCH/EPDCCH/MPDCCH/SPDCCH) HARQ-ACKs and ACK in response to PDCCH/EPDCCH/MPDCCH/SPDCCH indicating downlink SPS release. For one configured serving cell the bundled 1 or 2 HARQ-ACK bits are transmitted using PUCCH format 1a or PUCCH format 1b, respectively.
For TDD HARQ-ACK multiplexing and a subframe n with 
, where 
is the number of elements in the set 
defined in Table 10.1.3.1-1B if the UE is configured with higher layer parameter shortProcessingTime and the corresponding PDCCH with CRC scrambled by C-RNTI is in the UE-specific search space for subframe-PDSCH and in Table 10.1.3.1-1 otherwise, spatial HARQ-ACK bundling across multiple codewords within a downlink or special subframe is performed by a logical AND operation of all the corresponding individual HARQ-ACKs. PUCCH format 1b with channel selection is used in case of one configured serving cell. For TDD HARQ-ACK multiplexing and a subframe n with 
, spatial HARQ-ACK bundling across multiple codewords within a downlink or special subframe is not performed, 1 or 2 HARQ-ACK bits are transmitted using PUCCH format 1a or PUCCH format 1b, respectively for one configured serving cell.
In the case of TDD and more than one configured serving cell with PUCCH format 1b with channel selection and more than 4 HARQ-ACK bits for 
multiple downlink or special subframes associated with a single UL subframe n, where 
is defined in Clause 10.1.3.2.1, and for the configured serving cells, spatial HARQ-ACK bundling across multiple codewords within a downlink or special subframe for all configured cells is performed and the bundled HARQ-ACK bits for each configured serving cell is transmitted using PUCCH format 1b with channel selection. For TDD and more than one configured serving cell with PUCCH format 1b with channel selection and up to 4 HARQ-ACK bits for
multiple downlink or special subframes associated with a single UL subframe n, where 
is defined in Clause 10.1.3.2.1, and for the configured serving cells, spatial HARQ-ACK bundling is not performed and the HARQ-ACK bits are transmitted using PUCCH format 1b with channel selection.
In the case of TDD and more than one configured serving cell with PUCCH format 3 and without PUCCH format 4/5 configured and more than 20 HARQ-ACK bits for 
multiple downlink or special subframes associated with a single UL subframe n, where 
is the number of elements in the set 
defined in Clause 10.1.3.2.2 and for the configured serving cells, spatial HARQ-ACK bundling across multiple codewords within a downlink or special subframe is performed for each serving cell by a logical AND operation of all of the corresponding individual HARQ-ACKs and PUCCH format 3 is used. For TDD and more than one configured serving cell with PUCCH format 3 and up to 20 HARQ-ACK bits for 
multiple downlink or special subframes associated with a single UL subframe n, where 
is the number of elements in the set 
defined in Clause 10.1.3.2.2 and for the configured serving cells, spatial HARQ-ACK bundling is not performed and the HARQ-ACK bits are transmitted using PUCCH format 3.
For TDD with PUCCH format 3 without PUCCH format 4/5 configured, a UE shall determine the number of HARQ-ACK bits, 
, associated with an UL subframe/slot n
according to 
where 
is the number of configured cells, and 
is the number of HARQ-bits for the c-th serving cell defined in Clause 7.3.
TDD HARQ-ACK feedback procedures for one configured serving cell are given in Clause 10.1.3.1 and procedures for more than one configured serving cell are given in Clause 10.1.3.2.
10.1.3.1 TDD HARQ-ACK procedure for one configured serving cell
HARQ-ACK transmission on two antenna ports 
is supported for PUCCH format 1a/1b with TDD HARQ-ACK bundling feedback mode and for PUCCH format 3.
A UE that supports aggregating more than one serving cell with frame structure type 2 can be configured by higher layers for HARQ-ACK transmission on two antenna ports 
for PUCCH format 1b with channel selection.
The TDD HARQ-ACK procedure for a UE configured with PUCCH format 3 is as described in Clause 10.1.3.2.2 when the UE receives PDSCH and/or SPS release PDCCH/EPDCCH only on the primary cell.
If the UE is not configured with the higher layer parameter EIMTA-MainConfigServCell-r12, and the UE is not configured with the higher layer parameter shortProcessingTime, for TDD HARQ-ACK bundling or TDD HARQ-ACK multiplexing for one configured serving cell and a subframe n with 
where 
is the number of elements in the set 
defined in Table 10.1.3.1-1, the UE shall use PUCCH resource 
for transmission of HARQ-ACK in subframe 
for 
mapped to antenna port p for PUCCH format 1a/1b, where
– If there is PDSCH transmission indicated by the detection of corresponding PDCCH/EPDCCH or there is PDCCH/EPDCCH indicating downlink SPS release within subframe(s) 
, where 
and 
(defined in Table 10.1.3.1-1) is a set of M elements 
depending on the subframe n and the UL/DL configuration (defined in Table 4.2-2 in [3]), and if PDCCH indicating PDSCH transmission or downlink SPS release is detected in subframe 
, where 
is the smallest value in set 
such that UE detects a PDCCH/EPDCCH indicating PDSCH transmission or downlink SPS release within subframe(s) 
and 
, the UE first selects a 
value out of {0, 1, 2, 3} which makes 
and shall use 
for antenna port 
, where 
is configured by higher layers, 
, and 
is the number of the first CCE used for transmission of the corresponding PDCCH in subframe 
and the corresponding m. When two antenna port transmission is configured for PUCCH format 1a/1b, the PUCCH resource for HARQ-ACK bundling for antenna port 
is given by

, where 
and 
is defined in Table 10.1.3.1-1, the UE shall use PUCCH format 1a/1b and PUCCH resource 
with the value of 
is determined according to higher layer configuration and Table 9.2-2. For a UE configured for two antenna port transmission for PUCCH format 1a/1b and HARQ-ACK bundling, a PUCCH resource value in Table 9.2-2 maps to two PUCCH resources with the first PUCCH resource 
for antenna port 
and the second PUCCH resource 
for antenna port 
, otherwise, the PUCCH resource value maps to a single PUCCH resource 
for antenna port 
.
– If there is PDSCH transmission indicated by the detection of corresponding PDCCH/EPDCCH or there is PDCCH/EPDCCH indicating downlink SPS release within subframe(s) 
, where 
and

depending on the subframe n and the UL/DL configuration (defined in Table 4.2-2 in [3]), and if EPDCCH indicating PDSCH transmission or downlink SPS release is detected in subframe 
, where 
is the smallest value in set 
such that UE detects a PDCCH/EPDCCH indicating PDSCH transmission or downlink SPS release within subframe(s) 
and 
, the UE shall use
– if EPDCCH-PRB-set 
is configured for distributed transmission
– if EPDCCH-PRB-set 
is configured for localized transmission

, where 
is the number of the first ECCE (i.e. lowest ECCE index used to construct the EPDCCH) used for transmission of the corresponding DCI assignment in EPDCCH-PRB-set 
in subframe 
and the corresponding m, 
for EPDCCH-PRB-set 
is configured by the higher layer parameter pucch-ResourceStartOffset-r11 ,

which is described in Clause 6.8A.5 in [3]. If 
, 
is determined from the HARQ-ACK resource offset field in the DCI format of the corresponding EPDCCH as given in Table 10.1.2.1-1. If 
, 
is determined from the HARQ-ACK resource offset field in the DCI format of the corresponding EPDCCH as given in Table 10.1.3.1-2. If the UE is configured to monitor EPDCCH in subframe 
, 
is equal to the number of ECCEs in EPDCCH-PRB-set 
configured for that UE in subframe
. If the UE is not configured to monitor EPDCCH in subframe 
,

10.1.3.2 TDD HARQ-ACK procedure for more than one configured serving cell
If a UE configured with EIMTA-MainConfigServCell-r12 for a serving cell, "UL/DL configuration" of the serving cell in the rest of this Clause refers to the UL/DL configuration given by the parameter eimta-HARQ-ReferenceConfig-r12 for the serving cell unless specified otherwise.
For TDD serving cell not configured for PUSCH/PUCCH transmission, "UL/DL configuration" of the serving cell in the rest of this Clause refers to the UL/DL configuration given by the parameter harq-ReferenceConfig-r14 for the serving cell unless specified otherwise.
The TDD HARQ-ACK feedback procedures for more than one configured serving cell are either based on a PUCCH format 1b with channel selection HARQ-ACK procedure as described in Clause 10.1.3.2.1 or a PUCCH format 3 HARQ-ACK procedure as described in Clause 10.1.3.2.2 or a PUCCH format 4 HARQ-ACK procedure as described in Clause 10.1.3.2.3 or a PUCCH format 5 HARQ-ACK procedure as described in Clause 10.1.3.2.4.
HARQ-ACK transmission on two antenna ports 
is supported for PUCCH format 3 and TDD with more than one configured serving cell.
If a UE is configured with more than one serving cell and the TDD UL/DL configurations of all serving cells are the same, TDD UL/DL configuration 5 with PUCCH format 3 is only supported for up to two configured serving cells.
If a UE is configured with two serving cells and the TDD UL/DL configuration of the two serving cells is the same, TDD UL/DL configuration 5 with PUCCH format 1b with channel selection for two configured serving cells is not supported. If a UE is configured with two serving cells and if the TDD UL/DL configuration of the two serving cells are not the same and if the DL-reference UL/DL configuration (as defined in Clause 10.2) of at least one serving cell is TDD UL/DL Configuration 5, PUCCH format 1b with channel selection is not supported.
If a UE is configured with the parameter EIMTA-MainConfigServCell-r12 for at least one serving cell and is configured with PUCCH format 3 without PUCCH format 4/5 configured, the UE is not expected to be configured with more than two serving cells having UL/DL Configuration 5 as a DL-reference UL/DL configuration.
HARQ-ACK transmission on two antenna ports 
is supported for PUCCH format 1b with channel selection and TDD with two configured serving cells.
