Abstract
A user device operating in dual-mode connectivity with a master node and a secondary node detects a failure of a secondary cell group associated with the secondary node (1004). In response, the user device suspends an secondary cell group transmission (1006). The user device generates a message related to a status of the SCG for transmission to the MN (1008) and transmitting the message to the MN when the SCG transmission is suspended (1010).
Claims20
A method in a user device operating in dual-mode (DC) connectivity with a master node (MN) and a secondary node (SN), the method comprising:
- detecting, by processing hardware, a failure of a secondary cell group (SCG) associated with the SN;
- suspending, by the processing hardware, an SCG transmission in response to detecting the failure of the SCG;
- generating, by the processing hardware, a message related to a status of the SCG for transmission to the MN, the message including a first SCG failure type and a second SCG failure type;
- and
- transmitting, by the processing hardware, the message to the MN when the SCG transmission is suspended.

(canceled)
A user device comprising:
- processing hardware;
- a non-transitory computer-readable medium storing instructions that, when executed by the processing hardware, cause the user device to:
- detect a failure of a secondary cell group (SCG) associated with the SN,
- suspend an SCG transmission in response to detecting the failure of the SCG,
- generate a message related to a status of the SCG for transmission to the MN, the message including a first SCG failure type and a second SCG failure type, and transmit the message to the MN when the SCG transmission is suspended.
