Abstract
A method performed by a user equipment, UE, includes receiving a request from a master node, MN, including a secondary cell group, SCG, configuration and a mode of operation of the SCG. The method includes determining the mode of operation of the SCG based on the indication of the mode of operation of the SCG. The method includes determining whether to perform random access or to delay performing random access based on the mode of operation of the SCG. UE apparatuses, computer programs, and computer program products are also provided.
Claims20
A method performed by a user equipment, UE, comprising:
- receiving a request from a master node, MN, including a secondary cell group, SCG, configuration and an indication that the SCG to be added is to operate in deactivated mode of operation;
- determining the mode of operation of the SCG to be a deactivated mode of operation based on the indication that the SCG to be added is to operate in deactivated mode of operation;
- and
- determining to delay performing random access.

A user equipment, UE, adapted to:
- receive a request from a master node, MN, for adding a secondary cell group, SCG, including a secondary cell group, SCG, configuration and an indication that the SCG to be added is to operate in deactivated mode in operation;
- determine the mode of operation of the SCG to be a deactivated mode of operation based on the indication that the SCG to be added is to operate in deactivated mode of operation;
- and
- determine to delay performing random access.
A user equipment, UE, comprising:
- processing circuitry;
- and
- memory coupled with the processing circuitry, wherein the memory includes instructions that when executed by the processing circuitry causes the UE to perform operations comprising:
- receiving a request from a master node, MN, for adding a secondary cell group, SCG, including a secondary cell group, SCG, configuration and an indication that the SCG to be added is to operate in deactivated mode of operation;
- determining the mode of operation of the SCG to be a deactivated mode of operation based on the indication that the SCG to be added is to operate in deactivated mode of operation;
- and
- determine to delay performing random access.
A computer program comprising program code to be executed by processing circuitry of a user equipment, UE, whereby execution of the program code causes the UE to perform operations comprising:
- receiving a request from a master node, MN, including a secondary cell group, SCG, configuration and an indication that the SCG to be added is to operate in deactivated mode of operation;
- determining the mode of operation of the SCG to be a deactivated mode of operation based on the indication that the SCG to be added is to operate in deactivated mode of operation;
- and
- determining to delay performing random access.
