Method and device in communication node for wireless communication

A base station for wireless communications, the bases station comprising:

• a transceiver;
• and
• a processor, wherein the transceiver and the processor are configured to:
• receives a second signaling,
• transmit a second message,
• receive a third information set when a target cell does not belong to a first candidate cell set, the second signaling comprising a first message;
• and
• receive a third signaling when the first target cell is a candidate cell in the first candidate cell set, the third signaling not comprising the first message, wherein either of the second signaling and the third signaling is transmitted, and
• wherein the first message is used to determine whether there is a Radio Link Failure (RLF)-related message, and
• wherein a first signaling is used for configurations for the first candidate cell set, and
• wherein as a response to a radio connection failure, the first target cell is determined, and
• whererin the second message is used to trigger transmission of the third information set, and
• wherein the third information set comprises a first sub-information-block, the first sub-information-block comprising the RLF-related message.

A method in user equipment (UE) for wireless communications, the method comprising:

• receiving a first signaling, the first signaling is used for configurations for a first candidate cell set;
• determining a radio connection failure;
• determining a first target cell as a response to the determined radio connection failure;
• transmitting a second signaling when the first target cell does not belong to the first candidate cell set, the second signaling comprising a first message;
• or
• transmitting a third signaling when the first target cell is a candidate cell in the first candidate cell set, the third signaling not comprising the first message, wherein either of the second signaling and the third signaling is transmitted;
• receiving a second message;
• and
• transmitting a third information set;
• wherein the first message is used to determine whether there is a Radio Link Failure (RLF)-related message, and
• wherein the second message is used to trigger transmission of the third information set, and
• wherein the third information set comprises a first sub-information-block, the first sub-information-block comprising the RLF-related message, and
• wherein the first target cell does not belong to the first candidate cell set.

A method in a base station for wireless communications, the method comprising:

• receiving a second signaling;
• transmitting a second message;
• receiving a third information set on a condition that a target cell does not belong to a first candidate cell set, the second signaling comprising a first message;
• receiving a third signaling on a condition that the first target cell is a candidate cell in the first candidate cell set, the third signaling not comprising the first message, wherein either of the second signaling and the third signaling is transmitted, and
• wherein the first message is used to determine whether there is a Radio Link Failure (RLF)-related message, and
• wherein a first signaling is used for configurations for the first candidate cell set, and
• wherein as a response to a radio connection failure, the first target cell is determined, and
• wherein the second message is used to trigger transmission of the third information set, and
• wherein the third information set comprises a first sub-information-block, the first sub-information-block comprising the RLF-related message.
