R1-2103954        Feature lead summary #2 on 104b-e-LTE-Rel17_NB_IoT_eMTC-01               Moderator (Huawei)

 

Agreement

The following options on the indication of downlink 16-QAM can be considered:

 

Agreement

For downlink power allocation to support 16QAM:

o   Option 1: Two power ratios are signaled

§  NPDSCH EPRE to NRS EPRE in symbols with NRS

§  NPDSCH EPRE to NRS EPRE in symbols without NRS

o   Option 2: the power ratio of NPDSCH EPRE to NRS EPRE in symbols with NRS is signaled, assuming the same transmit power of different symbols.

o   Option 3: the power ratio of NPDSCH EPRE to NRS EPRE in symbols without NRS is signaled, assuming the same transmit power of different symbols.

o   If the signaling(s) is(are) not indicated, the legacy power allocation is used.

§  i.e., the ratio of NPDSCH EPRE to NRS EPRE is 0dB for one NRS antenna port, and -3dB for two NRS antenna ports

o   FFS to reuse the existing parameter nrs-CRS-PowerOffset.

 

Agreement

If 16-QAM is configured for NPDSCH, the channel quality report for 16-QAM is based on NPDSCH transport block that achieves an error probability not exceeding 10% BLER.

From GTW sessions:

 

Agreement

In Rel-17, for the 14 HARQ process feature the HARQ-ACK delay solution will be supported with multiple solutions:

Alt-1 for full flexibility and Alt-2e for support of legacy delay

·        Alt-1: The HARQ-ACK delay is determined through an expression consisting of different subframe types (Using a similar principle as the PDSCH scheduling delay).

o   Without using more than 6 bits

o   FFS: How to minimize the overhead by using joint encoding

·        Alt-2e: The HARQ-ACK delay is determined following the legacy approach. That is, the “HARQ-ACK delay” is kept expressed in terms of “absolute subframes”.

o   The HARQ-ACK delay values and the length of the HARQ-ACK delay set will be based on

§  Alt-2e: “3 bits (same as legacy)”

§  FFS: Whether HARQ delay set is to use range1 or range2

·        RRC signaling will be used to configure between Alt-1 and Alt-2e

·        FFS: Signaling details

·        FFS: Joint encoding

 

R1-2106029        Feature Lead Summary [105-e-LTE-Rel17_NB_IoT_eMTC-02] checkpoint#2               Moderator (Ericsson)

 

Working Assumption

The PDSCH scheduling delay and HARQ-ACK delay are jointly encoded in a single DCI field:

·        The field uses no more than 7 bits if Alt-1 is configured.

·        The field is 5 bits if Alt-2e is configured.

·        FFS: Details of the joint encoding.

·        FFS: Legacy DCI fields that might be re-purposed for the jointly encoded solution of Alt-1 and Alt-2e respectively.

Note: Alt-1 expresses the HARQ-ACK delay as: (y) BL/CE DL subframe + 1 subframe + (z) BL/CE UL subframes, where y = {0, 1, 2, … 11} and z = {1, 2, 3}.

 

Conclusion:

In Rel-17, for the 14 HARQ processes feature:

When the HARQ-ACK delay is configured to use Alt-1 “PUCCH using Repetition = 1 is postponed”, whereas when the HARQ-ACK delay is configured to use Alt-2e “PUCCH using Repetition = 1 is not postponed (legacy behavior)”.

 

Agreement

In Rel-17, the 14 HARQ processes feature is applicable for HD-FDD Cat M1 UEs in CE Mode A only.

Confirm the working assumption:

Working Assumption

·        For the indication of 16-QAM in uplink

·        The “Modulation and coding scheme” field in DCI Format N0 is utilized as in legacy for scheduling QPSK.

·        One reserved state in the “Modulation and coding scheme” field in DCI Format N0 is utilized to indicate the use of 16QAM.

·        The “Repetition number” field in DCI Format N0 is utilized to indicate the TBS indices (i.e., I_TBS indices from 14 to 21) for 16-QAM in UL.

From GTW session:

Agreement

Confirm the below Working Assumption for Alt-2e with following updates

The PDSCH scheduling delay and HARQ-ACK delay are jointly encoded in a single DCI field:

·        The field is 5 bits if Alt-2e is configured.

·        FFS: Details of the joint encoding.

·        FFS: Legacy DCI fields that might be set to zero bits in length for the jointly encoded solution Alt-2e.

For Alt-1, it will be separate discussion based existing working assumption

 

Agreement

Confirm the below Working Assumption for Alt-1 with following updates

The PDSCH scheduling delay and HARQ-ACK delay are jointly encoded in a single DCI field:

·        The field is no more than 7 bits if Alt-1 is configured.

·        FFS: Details of the joint encoding.

·        FFS: Legacy DCI fields that might be set to zero bits in length for the jointly encoded solution Alt-1.

Note: Alt-1 expresses the HARQ-ACK delay as: (y) BL/CE DL subframe + 1 subframe + (z) BL/CE UL subframes, where y = {0, 1, 2, … 11} and z = {1, 2, 3}.

Agreement

In Rel-17, for the 14 HARQ processes feature the following updates on the technical specification are to be performed.

·        The maximum number of received PDSCH receptions pending HARQ-ACK is set to W = 12 (in Sect. 7.3.1 of TS 36.213) when the UE is configured with 14 HARQ processes.

Agreement

In Rel-17, one option will be down selected from Opt-2 and Opt-3 for the 14 HARQ processes feature the “Repetition number” field in RAN1#107e:

·        Opt-2: 0-bits when the 14 HARQ processes feature is configured (i.e., 2-bits from this field become available for jointly-encoding purposes).

·        Opt-3: 2-bits as in legacy.

From Nov 16th GTW session

Agreement

Confirm the following Working Assumption:

For the joint encoding of “PDSCH Scheduling delay” and “HARQ-ACK delay” when Alt-2e is configured, the HARQ-ACK delay set has a size of:

·        Alt-C:

o   12 elements: HARQ-ACK delay set = {a, b, c, d, e, f, g, h, i, j, k, l} for the PDSCH Scheduling delay expression associated to the delay of 2.

o   elements: HARQ-ACK delay set = {o, p, q, r, s, t, u, v, x, w} for the two PDSCH Scheduling delay expressions associated to the delay of 7.

FFS: The values of {a, b, c, d, e, f, g, h, i, j, k, l}, {o, p, q, r, s, t, u, v, x, w} where some of these elements may share the same value.

 

Agreement

For the joint encoding of “PDSCH Scheduling delay” and “HARQ-ACK delay” when Alt-2e is configured, the HARQ-ACK delay sets consist of the following elements:

·        Alt-C2:

o   12 elements: HARQ-ACK delay set = {4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 15, 17} for the PDSCH Scheduling delay expression associated to the delay of 2.

o   elements: HARQ-ACK delay set = {4, 5, 10, 12, 13, 14, 15, 16, 17, 18} for the two PDSCH Scheduling delay expressions associated to the delay of 7.

Agreement

In Rel-17, for the 14 HARQ processes feature the “Repetition number” field is:

·        Opt-3: 2-bits as in legacy

Note: Further optimization for using Repetition number” field is not pursued

 

Agreement

In Rel-17, for the 14 HARQ processes feature the “HARQ-ACK delay” field is:

·        0-bits when the 14 HARQ processes feature is configured (i.e., 3-bits from this field become available for jointly-encoding purposes).

Decision: As per email decision posted on Feb 26th,

Agreement

The TP to section 5.4.3 of TS36.211 is endorsed.

5.4.3        Mapping to physical resources

< Unchanged parts are omitted >

For BL/CE UEs, PUCCH is transmitted with  repetitions.

-    The BL/CE UE is not expected to transmit with  when CE-PDSCH-14HARQ-Configce-PDSCH-14HARQ-Config is configured.

< Unchanged parts are omitted >

 

Agreement

The TP to section 7.1.11 of TS36.213 is endorsed.

7.1.11      PDSCH subframe assignment for BL/CE UE

A BL/CE UE shall upon detection of a MPDCCH with DCI format 6-1A/6-1B/6-2 intended for the UE, 

decode the corresponding PDSCH in subframe(s) n+ki with i = 0, 1, …, NTBN-1 according to the MPDCCH, where

< Unchanged parts are omitted >

-    otherwise,

-    subframe(s) ni n+ki with i=0,1,…, NTBN-1 are NTBN consecutive BL/CE DL subframe(s), where , and subframe n+x is the jth BL/CE DL subframe after subframe n, and j is given by the value of the PDSCH scheduling delay option as defined in [4] if the UE is configured with CEModeA and 'PDSCH scheduling delay and HARQ-ACK delay for 14 HARQ' field is present in the corresponding DCI, j=2 otherwise.

< Unchanged parts are omitted >

 

Decision: As per email decision posted on Mar 3rd,

Conclusion

In Rel-17 for the 14 HARQ process feature, the use of the “Repetition Number” field was intended to address adverse radio condition where at most 1 HARQ process along with PDSCH repetitions are suitable to be used.

·        Other scenarios making use of PDSCH repetitions (e.g., combining the use of repetitions/no-repetitions) are not precluded subject to be compliant to the “PDSCH scheduling delays” and “HARQ-ACK delays” introduced in Rel-17.
