Pcell support for xDL/1UL in all aggregated carriers is agreed to be mandatory in the UE for Rel-12 onwards at RAN4#74
for all combinations except A2, A4, and FDD/TDD.
For A2, A4, and FDD+TDD combinations, companies shall supply:
• “Exception information” on existing combinations where Pcell cannot be mandatorily supported by the UE for
xDL/1UL on all aggregated carriers
• “Request” for existing combinations where Pcell is required to be mandatorily supported by the UE for xDL/1UL
on all aggregated carriers
For existing A2, A4, and FDD+TDD combinations where a “request” but no “exception info” is provided by next meeting,
Pcell in all aggregated carrier will be agreed as mandatory for UE for Rel-12 onwards.
For A2, A4, and FDD+TDD combinations where a “request” and “exception info” is provided by next meeting, a decision
on mandatory Pcell support in all aggregated carrier will be made in time for June RAN plenary.
For A2, A4, and FDD+TDD combinations where no “request” is provided by next meeting, Pcell support in the UE shall be
optional for Rel-12.
•
For new xDL/1UL WIDs (rel-13 and onwards) it shall be described in the WID for which aggregated carriers Pcell shall be
defined in the spec. Also it shall be defined in the WID the aggregated carriers for which Pcell is required to be
mandatorily supported by UEs, otherwise it is optional for the Release in which it is added to the spec.
