From Nov 15th session
Agreement
In an LS to RAN4, in addition to reuse 5 MHz channel bandwidth, RAN1 suppose only 3 MHz channel bandwidth is supported, and would like to get RAN4 responses on the maximum transmission bandwidth (the number of PRBs) for this channel BW.
Agreement
RAN1 would like to ask RAN4 if finer sync. raster for the 3MHz and/or 5MHz channel bandwidth is feasible, as well as any input from RAN1 for RAN4’s answer to this question.
Agreement
Before getting RAN4 responses, RAN1 assume maximum transmission bandwidth, 15RBs or 16RBs for 3 MHz channel BW for evaluation and analysis.
Note: include agreement into the LS
Agreement
Before getting RAN4 responses, RAN1 assume that the UE could know which RBs are used for SSB transmission after PSS/SSS is detected for evaluation and analysis.
Note: it does not mean indication signaling is needed.
Note: include this agreement into the LS.

Question 1: RAN1’s understanding is that in addition to reuse 5 MHz channel bandwidth, RAN1 suppose only 3 MHz channel bandwidth is supported, and would like to get RAN4 responses on the maximum transmission bandwidth (the number of PRBs) for this channel BW
Question 2: RAN1 have discussed aspects related to synch raster in the spectrum of interest. RAN1 would like to ask RAN4 if finer sync. raster for the 3MHz and/or 5MHz channel bandwidth is feasible, as well as if RAN4 needs any input from RAN1.

From Tuesday session
Agreement
For 3MHz channel BW, the 15 PRBs CORESET#0 is obtained by puncturing the 9 upper PRBs of 𝑁RB CORESET = 24 CORESET#0.
Agreement (revised in Friday session)
For 3MHz channel BW, for kssb and PRB offset for the determining the CORESET#0 position in frequency domain,
Note: the above assumes that PRB offset to be the frequency gap between the first PRB of the actually transmitted 12/15 PRBs CORESET#0 and the first CRB overlapping with the first PRB of the actually transmitted 12 PRBs SS/PBCH block, how to capture it in the specification is left to editors.
R1-2308422 Summary#2 of discussion on enhancements to operate NR on dedicated spectrum less than 5MHz Moderator (Lenovo)
From Wednesday session
Agreement
For CORESET#0 for less than 5MHz transmission bandwidth, the UE assumes the same precoding being used per REG bundle.
Note: This depends on UE implementation whether channel estimation can be performed for partial REG bundle, if any.
R1-2308587 Summary#3 of discussion on enhancements to operate NR on dedicated spectrum less than 5MHz Moderator (Lenovo)
From Friday session
Agreement
Revise the previous agreement as below,
Agreement
For 3MHz channel BW, for kssb and PRB offset for the determining the CORESET#0 position in frequency domain,
· kssb follows legacy configuration.
o Note: based on existing specifications, UE
does not expect other values than kssb = 0 for 12PRBs CORESET#0,
[kssb
= 8 [or 20] for 15PRBs CORESET#0 with offset 0 PRBs, kssb = 4 [or 16] for
15RPBs CORESET#0 with offset 2 PRBs]
· PRB offset
o For 12 PRBs CORESET#0 transmission BW, PRB offset = 0
o For 15 PRBs CORESET#0 transmission BW, at
least PRB offset = 0, [2] 2 are
supported
§ FFS if offset = 1, 3 are supported.
Note: the above assumes that PRB offset to be the frequency gap between the first PRB of the actually transmitted 12/15 PRBs CORESET#0 and the first CRB overlapping with the first PRB of the actually transmitted 12 PRBs SS/PBCH block, how to capture it in the specification is left to editors.
Note: the range of the PRB offsets is only applicable to the introduced new sync. raster points for 3MHz channel BW and 100kHz channel raster.
Agreement
For 3MHz channel BW, Table 13-0 is used by the UE for CORESET#0 configuration only when the detected SSB is from a new synch raster point in RAN4.
FFS: any specification impact.
Agreement
For dedicated spectrum with less than 5MHz transmission BW, if a UE is not provided initialDownlinkBWP, the location and size of the initial DL BWP is equal to that of CORESET#0 transmission BW, i.e.,
Note: whether/how to reflect the above is up to Editor.
Conclusion (based on RAN1#113 agreement)
For 2 symbols and 3 symbols for 15 PRBs CORESET#0, both interleaved and non-interleaved CCE to REG mapping are supported.
Agreement
For 5MHz channel BW, 20 PRBs CORESET#0 transmission BW is supported.

From Tuesday session
Agreement
Endorse the TP below for TS 38.300 and send it in an LS to RAN2
Reason for change: |
Introduction of changes related to WI “NR support for dedicated spectrum less than 5MHz for FR1” |
|
|
Summary of change: |
Adding a remark that with 3MHz Channel BW the PBCH is punctured down to 144 subcarriers (i.e. 12 PRBs) |
|
|
Consequences if not approved: |
Incomplete description of the PBCH in case of operation with 3MHz CBW. |
--- < Start of the Text Proposal > ---
<Unchanged text omitted>
5.2.4 Synchronization signal and PBCH block
The Synchronization Signal and PBCH block (SSB) consists of primary and secondary synchronization signals (PSS, SSS), each occupying 1 symbol and 127 subcarriers, and PBCH spanning across 3 OFDM symbols and 240 subcarriers, but on one symbol leaving an unused part in the middle for SSS as show in Figure 5.2.4-1. For the 3 MHz channel bandwidth, the PBCH is further equally punctured from both edges to span 144 subcarriers. The possible time locations of SSBs within a half-frame are determined by sub-carrier spacing and the periodicity of the half-frames where SSBs are transmitted is configured by the network. During a half-frame, different SSBs may be transmitted in different spatial directions (i.e. using different beams, spanning the coverage area of a cell).
Within the frequency span of a carrier, multiple SSBs can be transmitted. The PCIs of SSBs transmitted in different frequency locations do not have to be unique, i.e. different SSBs in the frequency domain can have different PCIs. However, when an SSB is associated with an RMSI, the SSB is referred to as a Cell-Defining SSB (CD-SSB). A PCell is always associated to a CD-SSB located on the synchronization raster.
Figure 5.2.4-1: Time-frequency structure of SSB
Polar coding is used for PBCH.
The UE may assume a band-specific sub-carrier spacing for the SSB unless a network has configured the UE to assume a different sub-carrier spacing.
PBCH symbols carry its own frequency-multiplexed DMRS.
QPSK modulation is used for PBCH.
The PBCH physical layer model is described in TS 38.202 [20].
