1. A method of operation by a wireless communication device operating in a wireless communication network, the method comprising:
receiving a first indicator or a second indicator singularly, or receiving both indicators jointly, wherein a radio network node in the wireless communication network uses the first and second indicators to indicate what the operational state of a serving cell in the network shall be for the wireless communication device, where the operational state can be any one of an activated state, a deactivated state, and a dormant state; and
determining the indicated operational state in dependence on:
received values of the first and second indicators, responsive to joint reception of the first and second indicators; and
a received value of the first or second indicator and a current operational state, responsive to singular reception of the first or second indicator.
