Question: Upon receiving a Candidate Cell TCI States Activation/Deactivation MAC Control Element (MAC CE) on a Serving Cell, what action does the MAC entity take regarding the information contained in the MAC CE?
Option 1: The MAC entity forwards the information to higher layers for further processing and ignores lower layers.
Option 2: The MAC entity indicates to lower layers the information regarding the Candidate Cell TCI States Activation/Deactivation MAC CE.
Option 3: The MAC entity discards the MAC CE if it's not relevant to the currently active cells.
Option 4: The MAC entity only logs the receipt of the MAC CE for network analytics.
Explanation: When a Candidate Cell TCI States Activation/Deactivation MAC CE is received on a Serving Cell, the MAC entity communicates the relevant information to lower layers. This ensures seamless integration and execution of activation/deactivation commands across necessary network components, reflecting a technical requirement for interoperability and efficient operation in telecom environments.
