Abstract
There is provided a method at a user equipment, the method comprising: entering a radio resource control, RRC, inactive mode; determining which carriers are to be measured during the RRC inactive mode; performing measurements of the determined carriers during the RRC inactive mode; providing the results of the measurements to a network upon entering an RRC connected mode.
Claims13
An apparatus, comprising:
- at least one processor and at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
- acquire from a network a configuration for at least one secondary cell;
- enter a radio resource control, RRC, inactive mode;
- maintain at least part of the configuration during the inactive mode;
- determine, based on the configuration, which carriers are to be measured during the RRC inactive mode;
- perform measurements of the determined carriers during the RRC inactive mode;
- provide the results of the measurements to the network upon entering an RRC connected mode,
- wherein only a subset of the carriers indicated in the configuration are to be measured, and
- wherein the subset includes those carriers that were activated within a predetermined duration before the entering the RRC inactive mode.

An apparatus, comprising:
- at least one processor and at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:

- provide the results of the measurements to the network upon entering an RRC connected mode,
- wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus further to:
- acquire information of a validity duration indicating how long the determination of which carriers are to be measured during the RRC inactive mode is valid,
- wherein the validity duration is indicated separately for each carrier that is to be measured, wherein at least two carriers to be measured have different validity durations.
