Abstract
A method, network node and wireless device for Scell activation/deactivation are disclosed. According to one aspect, a method includes determining if a serving cell of a wireless device (WD) is activated. The method further includes causing transmission of at least one medium access control (MAC) control element (CE) to deactivate a first semi-persistent channel state information (CSI) resource and a first semi-persistent (SP) CSI reporting configuration.
Claims26
A network node configured to communicate with a wireless device, WD, the network node configured to determine if a serving cell of the WD is activated;
- and
- when the serving cell of the WD is activated, transmit at least one medium access control, MAC, control element, CE, to deactivate a first semi-persistent, SP, channel state information reference signal, CSI-RS, resource configuration and a first SP channel state information, CSI, reporting configuration.

A method implemented in a network node, the method comprising:
- determining if a serving cell of the WD is activated;
- and
- when the service cell of the WD is activated, transmitting at least one medium access control, MAC, control element, CE, to deactivate a first semi-persistent, SP, channel state information reference signal, CSI-RS, resource configuration and a first SP CSI reporting configuration.

A wireless device, WD, configured to communicate with a network node, the WD configured to:
- receive at least one medium access control, MAC, control element, CE, from the network node to activate a first semi-persistent channel state information reference signal, SP CSI-RS, resource configuration and a first SP channel state information, CSI, reporting configuration;
- and
- cause transmission of a valid CSI based at least in part on a configured CSI resource and report responsive to the at least one MAC CE.
