Abstract
A system and method for improving mobility performance. The system and method include receiving, by a target master wireless communication node (MN) from a source master wireless communication node (MN), a handover request to begin a handover procedure; and transmitting, by the target MN to a target secondary wireless communication node (SN), a first message to inform the target SN about a type of SN addition or change procedure to perform the handover request, wherein the first message causes the target SN to send a second message to the target MN to inform the target MN of one or more configured primary secondary (PSCells).
Claims16
A method comprising:
- receiving, by a target master wireless communication node (MN) from a source master wireless communication node (MN), a handover request to begin a handover procedure;
- transmitting, by the target MN to a target secondary wireless communication node (SN), a first message to inform the target SN about a type of SN addition or change procedure to perform the handover request, the type of SN addition or change procedure selected from among a first type comprising a conditional primary secondary cell addition or change (CPAC) procedure or a second type comprising a primary secondary cell (PSCell) addition or change for a conditional handover (CHO) procedure;
- receiving, by the target MN from the target SN, a second message which informs the target MN of one or more configured PSCells;
- and
- transmitting, by the target MN to the source MN, a handover request acknowledge message which includes the one or more configured PSCells.
2 more elements
A target master wireless communication node (MN), comprising:
- at least one processor and a transceiver configured to:
- receive, from a source master wireless communication node (MN), a handover request to begin a handover procedure;
- and
- transmit, to a target secondary wireless communication node (SN), a first message to inform the target SN about a type of SN addition or change procedure to perform the handover request, the type of SN addition or change procedure selected from among a first type comprising a conditional primary secondary cell addition or change (CPAC) procedure or a second type comprising a primary secondary cell (PSCell) addition or change for a conditional handover (CHO) procedure;
- receive, from the target SN, a second message which informs the target MN of one or more configured PSCells;
- and
- transmit, to the source MN, a handover request acknowledge message which includes the one or more configured PSCells.

A method comprising:
- transmitting, by a source master wireless communication node (MN) to a target master wireless communication node (MN), a handover request to begin a handover procedure,
- wherein the target MN transmits to a target secondary wireless communication node (SN), a first message to inform the target SN about a type of SN addition or change procedure to perform the handover request, the type of SN addition or change procedure selected from among a first type comprising a conditional primary secondary cell addition or change (CPAC) procedure or a second type comprising a primary secondary cell (PSCell) addition or change for a conditional handover (CHO) procedure, and receives, from the source SN, a second message which informs the target MN of one or more configured PSCells;
- and
- receiving, by the source MN from the target MN, a handover request acknowledge message which includes the one or more configured PSCells.
1 more element
A source master wireless communication node (MN), comprising:
