HANDOVER MECHANISM WITH PRE-SCHEDULING CONSECUTIVE GRANTS AND PRE-CALCULATED TIMING ADVANCE

摘要

Various communication systems may benefit from mechanisms for transferring control over or communication with terminal devices. For example, certain wireless communication systems may benefit from a handover mechanism with pre-scheduling consecutive grants and pre calculated timing advance. A method can include receiving pre-scheduled uplink grants in a plurality of sub-frames for an incoming user equipment without random access channel The method can also include receiving a timing advance value or performing timing advance calculation for the incoming user equipment without random access channel The method can further include sending a plurality of duplicate messages within the plurality of sub-frames based on the received timing advance value or calculated timing advance.
