US 11,689,977 B2 · Method and system to handle handover procedure in multi TRP system

Abstract

The present disclosure relates to wireless communication system and more particularly relates to the design of handover procedures for multi TRP system for a mobile station and other devices. Multi TRP per cell or cell less or cell free architecture removes the boundaries of the cell. A method of handover for a UE in a multi TRP system comprising selecting a set of candidate TRPs for the UE for a handover operation and receiving a measurement report from the UE. The source node determines a trigger for handover of the UE in response to the measurement report and compares a configuration of the source node with a configuration of a candidate TRP from the set of candidate TRPs. The source node triggers a handover command to perform a handover operation for the UE with at least one candidate TRP based on a result of the comparison.

Dependent claims

A method of a source node for a handover operation in a wireless communication system, the method comprising:

selecting a set of candidate transmission/reception points (TRPs) for a user equipment (UE) for the handover operation;
receiving, from the UE, a measurement report;
determining a trigger operation for the handover operation of the UE in response to receiving the measurement report;
comparing a configuration of the source node with a configuration of a candidate TRP from the set of candidate TRPs, wherein comparing the configuration of the source node with the configuration of the candidate TRP comprises comparing configurations of at least one of radio resource control (RRC) layers, packet data convergence protocol (PDCP) layers, medium access control (MAC) layers, radio link control (RLC) layers, or physical layers of the source node and the candidate TRP;
and
triggering a handover command to perform the handover operation for the UE with at least one candidate TRP based on a result of the comparison.

An apparatus of a source node for a handover operation in a wireless communication system, the apparatus comprising:

a transceiver;
and
one or more processors operably connected to the transceiver, the one or more processors configured to:
select a set of candidate transmission/reception points (TRPs) for a user equipment (UE) for the handover operation;
receive, from the UE, a measurement report;
determine a trigger operation for the handover operation of the UE in response to receiving the measurement report;
compare a configuration of the source node with a configuration of a candidate TRP from the set of candidate TRPs, wherein for comparing the configuration of the source node with the configuration of the candidate TRP, the one or more processors are configured to compare configurations of at least one of radio resource control (RRC) layers, packet data convergence protocol (PDCP) layers, medium access control (MAC) layers, radio link control (RLC) layers, or physical layers of the source node and the candidate TRP;
and
trigger a handover command to perform the handover operation for the UE with at least one candidate TRP based on a result of the comparison.
