Overview Multi-carrier support is more than optional –Fast handover –Load balance –Multicast/broadcast services Modification to current control/data plane processing flow in SDD –To highlight the interactions between multi-carrier support and other function blocks

Proposed Text [In 80216m-08_003, Section 8.2, add the following text at line 14] Multi-carrier block enables multiple RF carriers to be deployed in contiguous or noncontiguous spectrum, and provides MS/BS abilities to distribute and handle control/data plane messages among multiple RF carriers. Multi-carrier block also interacts with and advances the performance of the following function blocks: –Mobility Management: Fast handover using multiple RF carriers. MS can proceeds its normal operation with serving BS on one RF carrier while perform HO procedures such as scanning and network reentry with target BS on another RF carrier. –Radio Resource Management: Flexible resource planning and dynamic load balance across multiple RF carriers. Aggregation of multiple RF carriers can be used to create wideband channels for users demanding high peak data rates. BS can also dynamically distribute its users across multiple RF carriers according to the traffic load. –MBS: Coexistence/seamless switching between unicast and multicast/broadcast services and non-interrupted MBS zone switching. MBS can be deployed on dedicated RF carriers while unicast services are performed on separated RF carriers. Furthermore, MBS zone switching operations such as update of MCID and LCID can be performed on separated RF carrier to provide non-interrupted multicast/broadcast service during zone switching. 11
