Abstract
A first node of a radio access network (RAN) transmits (304), to a second node, a request to operate as a secondary node (SN) and provide dual connectivity (DC) to a user equipment (UE), with the first node operating as a master node (MN), the request including an indication of continuous conditional secondary cell addition or change (CPAC); receives (306), from the second node and in response to the request, a first conditional SN (C-SN) configuration; and transmits (308), to the UE, the first conditional SN configuration and a second conditional SN configuration related to at least one cell not associated with the second node
Claims24
A method implemented in a first node of a radio access network (RAN), the method comprising:
- transmitting, to a second node, a request to operate as a secondary node (SN) and provide dual connectivity (DC) to a user equipment (UE), with the first node operating as a master node (MN), the request including an indication of continuous conditional secondary cell addition or change (CPAC) which does not require new CPAC preparation from the RAN for a subsequent CPAC;
- receiving, from the second node and in response to the request, a first conditional SN (C-SN) configuration;
- and
- transmitting, to the UE, the first C-SN configuration and a second C-SN configuration related to at least one cell not associated with the second node.
A method implemented in a first node of a radio access network (RAN), the method comprising:
- transmitting, to a user equipment (UE) that communicates in dual connectivity (DC) with the first node as a master node (MN) and a second node of the RAN as a secondary node (SN), a conditional secondary node (C-SN) configuration related to a plurality of candidate cells for connecting subject to one or more respective conditions, the plurality of candidate cells including a candidate cell of a candidate SN;
- receiving an indication that the UE connected to the candidate cell;
- and
- transmitting, to the SN, a notification based on whether the candidate SN is for continuous conditional cell changes associated with the UE performing a subsequent conditional cell change based on the C-SN configuration that does not require new conditional secondary cell addition or change (CPAC) preparation from the RAN.

A first node in a radio access network (RAN) comprising processing hardware and a transceiver, the node configured to:
- transmit, to a second node, a request to operate as a secondary node (SN) and provide dual connectivity (DC) to a user equipment (UE), with the first node operating as a master node (MN), the request including an indication of continuous conditional secondary cell addition or change (CPAC) which does not require new CPAC preparation from the RAN for a subsequent CPAC;
- receive, from the second node and in response to the request, a first conditional SN (C-SN) configuration;
- and
- transmit, to the UE, the first conditional SN configuration and a second conditional SN configuration related to at least one cell not associated with the second node.
