Abstract
Embodiments herein relate to for example a method performed by a network node for determining a carrier aggregation (CA) limit for UE configuration with monitoring capability, based on: a downlink (DL) sub-slot structure and/or pattern of a DL slot; a set of overlapping spans across scheduled cells; start and end times for spans across component carriers; and/or spans at least partially overlapping a CA limit window.
Claims23
A method by a network node comprising:
- determining a carrier aggregation, CA, limit for user equipment, UE, configuration with monitoring capability, based on:
- a downlink, DL-sub-slot structure and/or pattern of a DL slot;
- a set of overlapping spans across scheduling cells;
- start and end times for spans across component carriers;
- and/or spans at least partially overlapping a CA limit window.
-27. (canceled)
A method by a user equipment, UE, comprising:
- during physical downlink control channel, PDCCH, monitoring, dropping a PDCCH candidate when a total number of configured PDCCH candidates or non-overlapped control channel elements, CCEs, in a set of spans on a primary cell or primary secondary cell exceeds a per-span limit or exceeds a carrier aggregation, CA, limit.
(canceled)
A user equipment, UE, configured to:
- during physical downlink control channel, PDCCH, monitoring, drop a PDCCH candidate when a total number of configured PDCCH candidates or non-overlapped control channel elements, CCEs, in a set of spans on a primary cell or primary secondary cell exceeds a per-span limit or exceeds a carrier aggregation, CA, limit.
A network node configured to:
- determine a carrier aggregation, CA, limit for user equipment, UE, configuration with monitoring capability, based on:
- a downlink, DL-sub-slot structure and/or pattern of a DL slot;
- a set of overlapping spans across scheduling cells;
- start and end times for spans across component carriers;
- and/or spans at least partially overlapping a CA limit window.
