Question: In E-UTRAN, what is the scope of resource reservation signaled to a User Equipment (UE) on a Narrowband Internet of Things (NB-IoT) non-anchor carrier to prevent overlap with New Radio (NR) when deployed within an NR carrier?
Option 1: Cell-specific for all transmission modes
Option 2: Carrier-specific for broadcast/multicast transmissions in idle mode
Option 3: UE-specific for all carriers in connected and idle modes
Option 4: Carrier-specific for unicast transmissions in connected mode
Explanation: Resource reservation to prevent overlap with NR on an NB-IoT non-anchor carrier is specifically tailored for efficient use of resources during unicast (one-to-one) communications when the UE is actively connected to the network. This approach ensures that resources are allocated effectively in the downlink and uplink, avoiding conflicts with NR deployments within the same carrier, particularly crucial for maintaining seamless connectivity in scenarios requiring low-bandwidth, high-penetration IoT communications.
