Enhanced resource allocation for multicast broadcast services

Abstract

A system, method and apparatus for mobile communications including an enhanced scheduled process is provided. A user equipment (UE) receives multicast broadcast configuration parameters. The UE determines that a first multicast broadcast service is associated with the DRX configuration parameters and that a second multicast broadcast service is not associated with the DRX configuration parameters. The UE receives first multicast broadcast data, associated with the first multicast broadcast service, based on scheduling information determined by monitoring a control channel using the DRX configuration parameters. The UE also receives second multicast broadcast data, associated with the second multicast broadcast service, based on the SPS configuration parameters and without monitoring the control channel for the scheduling information.
