Samsung patents faster 5G/6G handoffs by skipping setup steps
This patent describes a method for mobile devices to switch between cell towers in 5G or 6G networks. It allows the phone to start syncing with the new tower immediately after receiving a command, skipping certain bandwidth setup steps to reduce delay.
In the filing’s own words
The disclosure relates to a fifth-generation (5G) or sixth-generation (6G) communication system for supporting a higher data transmission rate. A method performed by a user equipment (UE) in a wireless communication system is provided. The method comprises receiving, from a base station, a physical downlink control channel (PDCCH) order for a random access procedure on a layer 1/layer 2 triggered mobility (LTM) candidate cell, transmitting a random access preamble for an early timing advance (TA) acquisition for the LTM candidate cell, based on the PDCCH order and receiving, from the base station, a cell switch command including a TA value of the LTM candidate cell, wherein a bandwidth part (BWP) operation is not performed for the LTM candidate cell based on the random access procedure being initiated by the PDCCH order.
What exactly they claim (claim 1)
1. A method performed by a user equipment (UE) in a wireless communication system, the method comprising: receiving, from a base station, a physical downlink control channel (PDCCH) order for a random access procedure on a layer 1/layer 2 triggered mobility (LTM) candidate cell; transmitting a random access preamble for an early timing advance (TA) acquisition for the LTM candidate cell, based on the PDCCH order; and receiving, from the base station, a cell switch command including a TA value of the LTM candidate cell, wherein a bandwidth part (BWP) operation is not performed for the LTM candidate cell based on the random access procedure being initiated by the PDCCH order.
