Question: For a UE (User Equipment) interested in receiving Multimedia Broadcast Multicast Services (MBMS) via Single-Cell Point-to-Multipoint (SC-PTM) on an Evolved Universal Terrestrial Radio Access Network (E-UTRA), which of the following procedures must be applied, excluding Narrowband Internet of Things (NB-IoT) UEs?
Option 1: Only SC-PTM procedures as described in the relevant RRC protocol specification.
Option 2: Only MBMS interest indication procedure as specified in the RRC protocol for MBMS.
Option 3: Both SC-PTM procedures and MBMS interest indication procedure, as per respective specifications.
Option 4: Neither SC-PTM nor MBMS interest indication procedures are required for MBMS service reception.
Explanation: For a UE to receive MBMS services via SC-PTM on an E-UTRA network (excluding NB-IoT UEs), it must utilize both the specific SC-PTM procedures for efficient point-to-multipoint transmission and the MBMS interest indication procedure. The latter is crucial for informing the network of the UE's interest in receiving particular MBMS services, ensuring resource allocation and service delivery. Combining both procedures enables seamless and targeted content delivery to interested UEs within a single cell.
