Event-Triggered CSI Reporting

A user equipment (UE), comprising:

• at least one processor;
• and
• at least one memory, the at least one memory storing instructions, that when
• executed by the least one processor, to cause the UE to at least:
• receive, from a node of a cellular communications network, configuration information relating to an event-triggered channel state information (CSI) reporting mode;
• and
• respond, while operating in the event-triggered CSI reporting mode in accordance with the configuration information, to an occurrence of a pre-defined event by providing report information to the cellular communications network, wherein i) the pre-defined event is related to a change in a selection associated with a set of transmission reception points (TRPs) ii) the selection is performed by the UE based on measurements of one or more reference signals, and iii) the report information relates to the change in the selection associated with the set of TRPs.

A cellular communications network node comprising:

• at least one processor;
• and
• at least one memory, the at least one memory storing instructions, that when executed by the least one processor, to cause the cellular communications network node to at least:
• provide to a user equipment (UE), configuration information relating to an event-triggered channel state information (CSI) reporting mode in which the UE is configured to report to the cellular communications network in response to the UE detecting an occurrence of an event relating to a change in a selection, that is associated with a set of transmission reception points (TRPs);
• and
• receive, from the UE, report information relating to detection, by the UE, of an occurrence of a predefined event that relates to a change in the selection associated with the set of TRPs.
