Title:	Text proposal for TS 38.213 Section 10.1 on agreements in [100b-e-NR-L1enh-URLLC-PDCCH enhancements-02]

Document for:	Discussion and decision

1	Introduction

The document captures text proposal to reflect the agreement from email discussion [100b-e-NR-L1enh-URLLC-PDCCH enhancements-02].

Reasons for change

Agreement:

Spans on cells from the downlink cells are considered as aligned if the union of PDCCH monitoring occasions on all the cells results to PDCCH monitoring according to the combination ; Otherwise, they are considered as not aligned.

Summary of changes

Incorporate the agreements from email discussion [100b-e-NR-L1enh-URLLC-PDCCH enhancements-02] to section 10.1 in TS 38.213.

Specs/Sections impacted

TS 38.213 Section 10.1

Consequences if not approved

The spec is incomplete.

---------------------------------Start of Text Proposal on TS 38.213 v16.1.0----------------------------------------

10.1	UE procedure for determining physical downlink control channel assignment

<Unchanged parts are omitted>

If a UE is configured only with downlink cells using Rel-16 PDCCH monitoring capability, and with of the downlink cells using combination for PDCCH monitoring, and having active DL BWPs using SCS configuration , where , a DL BWP of an activated cell is the active DL BWP of the activated cell, and a DL BWP of a deactivated cell is the DL BWP with index provided by firstActiveDownlinkBWP-Id for the deactivated cell, the UE is not required to monitor more than PDCCH candidates or more than non-overlapped CCEs

-	per span on the active DL BWP(s) of all scheduling cell(s) from the downlink cells, if the union of PDCCH monitoring occasions on all scheduling cell(s) from the downlink cells results to PDCCH monitoring according to the combination (X, Y)

where is a number of configured cells using Rel-16 PDCCH monitoring capability with SCS configuration . If a UE is configured with downlink cells using both Rel-15 PDCCH monitoring capability and Rel-16 PDCCH monitoring capability, is replaced by .

For each scheduled cell, the UE is not required to monitor on the active DL BWP with SCS configuration of the scheduling cell from the downlink cells using combination for PDCCH monitoring more than PDCCH candidates or more than non-overlapped CCEs per span.

A UE does not expect to be configured CSS sets that result to corresponding total, or per scheduled cell, numbers of monitored PDCCH candidates and non-overlapped CCEs per slot that exceed the corresponding maximum numbers per slot.

For same cell scheduling or for cross-carrier scheduling where a scheduling cell and scheduled cell(s) have DL BWPs with same SCS configuration , a UE does not expect a number of PDCCH candidates, and a number of corresponding non-overlapped CCEs per slot on a secondary cell to be larger than the corresponding numbers that the UE is capable of monitoring on the secondary cell per slot.

<Unchanged parts are omitted>
