Method, device and computer storage medium of communication
Embodiments of the present disclosure relate to methods, devices and computer readable media for communication. A method of communication comprises determining, at a terminal device, whether a first failure of a first access attempt to a first cell of a first network device occurs, the first network device being a secondary node serving the terminal device, a second network device being a master node serving the terminal device; and in accordance with a determination that the first failure occurs, transmitting at least first information about the first failure to the first network device or the second network device. In this way, a reporting of SCG failure information can be enhanced.
1 . A method of communication performed by a terminal device, the method comprising:
executing at least one of Conditional Primary Secondary Cell Group Cell (PSCell) Addition (CPA) and Conditional PSCell Change (CPC);
detecting a failure in the at least one of the CPA and the CPC; and
transmitting a Secondary Cell Group (SCG) failure information message, regarding the failure in the at least one of the CPA and the CPC, to a master node, wherein the SCG failure information message comprises:
an identity of a failed PSCell;
an identity of a previous PSCell of a secondary node;
a time duration from initialization of connection of the previous PSCell until a first SCG failure; and
first information of a random access procedure associated with the failure,
wherein the SCG failure information message is further sent from the master node to a candidate secondary node or a target secondary node, for the at least one of the CPA and the CPC.
2 . The method of claim 1 , wherein a type of the failure is a reconfiguration with a sync failure.
3 . The method of claim 1 , wherein a type of the failure is related to an access attempt.
4 . The method of claim 1 , wherein the SCG failure information message further comprises second information indicating a failure type.
5 . The method of claim 1 , wherein candidate cells and conditions for the at least one of the CPA and the CPC are determined by the master node.
6 . A method of communication performed by a master node, the method comprising:
receiving from a terminal device, a Secondary Cell Group (SCG) failure information message regarding a failure in at least one of Conditional Primary Secondary Cell Group Cell (PSCell) Addition (CPA) and Conditional PSCell Change (CPC), wherein the SCG failure information message comprises:
an identity of a failed PSCell;
an identity of a previous PSCell of a secondary node;
a time duration from initialization of connection of the previous PSCell until a first SCG failure; and
first information of a random access procedure associated with the failure; and
transmitting the SCG failure information message to a candidate secondary node or a target secondary node, for the at least one of the CPA and the CPC.
7 . The method of claim 6 , wherein a type of the failure is a reconfiguration with a sync failure.
8 . The method of claim 6 , wherein a type of the failure is related to an access attempt.
9 . The method of claim 6 , wherein the SCG failure information message further comprises second information indicating a failure type.
10 . The method of claim 6 , further comprising determining candidate cells and conditions for the at least one of the CPA and the CPC.
11 . A terminal device comprising:
a memory configured to store program instructions;
a processor configured to execute the program instructions stored in the memory, that, when executed:
executes at least one of Conditional Primary Secondary Cell Group Cell (PSCell) Addition (CPA) and Conditional PSCell Change (CPC);
detects a failure in the at least one of the CPA and the CPC; and
a transmitter configured to transmit a Secondary Cell Group (SCG) failure information message, regarding the failure in the at least one of the CPA and the CPC, to a master node, wherein the SCG failure information message comprises:
an identity of a failed Primary SCG Cell (PSCell);
an identity of a previous PSCell of a secondary node;
a time duration from initialization of connection of the previous PSCell until a first SCG failure; and
first information of a random access procedure associated with the failure,
wherein the SCG failure information message is further sent from the master node to a candidate secondary node or a target secondary node, for the at least one of the CPA and the CPC.
12 . The terminal device of claim 11 , wherein a type of the failure is a reconfiguration with a sync failure.
13 . The terminal device of claim 11 , wherein a type of the failure is related to an access attempt.
14 . The terminal device of claim 11 , wherein the SCG failure information message further comprises second information indicating a failure type.
15 . The terminal device of claim 11 , wherein candidate cells and conditions for the at least one of the CPA and the CPC are determined by the master node.
