Abstract

A user equipment, a method and an apparatus supporting Multimedia Broadcast Multicast Service (MBMS) service provided via Single Cell Point-To-Multipoint (SC-PTM) perform a cell reselection operation for selecting a cell different from a current serving cell as a serving cell. When the user equipment is in an enhanced coverage, the cell reselection is performed according to a ranking based on a radio quality irrespective of frequency priority, and when the user equipment is in the enhanced coverage and the user equipment is receiving or interested in receiving an MBMS service via the SC-PTM, the ranking is performed on cells belonging to a SC-PTM frequency where the MBMS service is provided.

1 . A user equipment supporting Multimedia Broadcast Multicast Service (MBMS) service provided via Single Cell Point-To-Multipoint (SC-PTM), the user equipment comprising:
 a processor and a memory coupled to the processor, wherein   the processor is configured to perform a cell reselection operation for selecting a cell different from a current serving cell as a serving cell,   when the user equipment is in an enhanced coverage, the processor is configured to perform the cell reselection according to a ranking based on a radio quality irrespective of frequency priority, and   when the user equipment is in the enhanced coverage and the user equipment is receiving or interested in receiving an MBMS service via the SC-PTM, the processor is configured to perform the ranking on cells belonging to a SC-PTM frequency where the MBMS service is provided   
     
     
         2 . A method used in a user equipment supporting Multimedia Broadcast Multicast Service (MBMS) service provided via Single Cell Point-To-Multipoint (SC-PTM), the method comprising:
 performing a cell reselection operation for selecting a cell different from a current serving cell as a serving cell, the user equipment, wherein   performing the cell reselection operation includes:
 performing a ranking based on a radio quality irrespective of frequency priority, when the user equipment is in an enhanced coverage; and 
 performing the cell reselection according to the ranking, wherein 
 performing the ranking includes: 
 when the user equipment is in the enhanced coverage and the user equipment is receiving or interested in receiving an MBMS service via the SC-PTM, performing the ranking on cells belonging to a SC-PTM frequency where the MBMS service is provided. 
   
     
     
         3 . An apparatus for controlling a user equipment supporting Multimedia Broadcast Multicast Service (MBMS) service provided via Single Cell Point-To-Multipoint (SC-PTM), the apparatus comprising:
 a processor and a memory coupled to the processor, wherein   the processor is configured to perform a cell reselection operation for selecting a cell different from a current serving cell as a serving cell,   when the user equipment is in an enhanced coverage, the processor is configured to perform the cell reselection according to a ranking based on a radio quality irrespective of frequency priority, and   when the user equipment is in the enhanced coverage and the user equipment is receiving or interested in receiving an MBMS service via the SC-PTM, the processor is configured to perform the ranking on cells belonging to a SC-PTM frequency where the MBMS service is provided.
