Examples of DCI in a sentence
Option 2: For UE BB bandwidth reduction, the number of PRBs scheduled in DCI can be larger than 25/12 PRBs for 15/30 kHz SCS for (Rel-17) broadcast MBS PDSCH with any PDSCH in next slot or MBS PDSCH repetition.
RAN1 would like to inform RAN2 about the following case, to consider, if needed, the UE behavior in the RAN2 specifications, and ask RAN2 for feedback if any:For UE BB complexity reduction, the case when the UE detects a DCI scheduling a Msg4 PDSCH transmission with a larger bandwidth than it can receive or process The case was also discussed in RAN1 in Question 2.7-2b of summary R1-2303936.
RAN1#114bis discussed the RAN2 reply and considered the following proposal without reaching a conclusion [3].RAN1#114bis High Priority Proposal 2.3-1c: Conclusion: It is up to UE implementation about how the physical layer notifies higher layers when it detects a DCI that schedules a Msg4 PDSCH transmission with a larger bandwidth than the UE can receive or process.
Company Option Comments vivo Option 2, but Current spec reads like the option 2: “A UE that has not indicated FG 48-2 is not required to process a PDSCH reception in slot that is scheduled by a DCI format with CRC scrambled by a G-RNTI for broadcast over a number of PRBs that is larger than 25 PRBs for 15 kHz SCS, or larger than 12 PRBs for 30 kHz SCS, when the PDSCH reception is with repetitions or when the UE receives another PDSCH in slot .” But it seems not clear how to understand the UE behavior.
Companies are invited to comment on the questions below.FL1 High Priority Question 4-1a: Please indicate your preference among the following options: Option 1: For UE BB bandwidth reduction, the number of PRBs scheduled in DCI is not larger than 25/12 PRBs for 15/30 kHz SCS for (Rel-17) broadcast MBS PDSCH with any PDSCH in next slot or MBS PDSCH repetition.
