US 2018/0020472 A1 · HANDOVER MECHANISM WITH PRE-SCHEDULING CONSECUTIVE GRANTS AND PRE-CALCULATED TIMING ADVANCE

Abstract

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.

Dependent claims

An apparatus, comprising:

at least one processor;
and
at least one memory including computer program code,
wherein the at least memory and computer program code are configured to, with the at least one processor, cause the apparatus at least to
receive pre-scheduled uplink grants in a plurality of sub-frames for an incoming user equipment without random access channel;
receive a timing advance value or performing timing advance calculation for the incoming user equipment without random access channel;
and
send a plurality of duplicate messages within the plurality of sub-frames based on the received timing advance value or calculated timing advance.
