Abstract
A wireless access node of a radio access network (RAN) that communicates over a radio interface with a wireless terminal. The wireless access node comprises transmitter circuitry and receiver circuitry. The transmitter circuitry is configured to transmit at least one message to the wireless terminal. The at least one message is configured to activate a first signaling data path and a second signaling data path. The first signaling data path and the second signaling data path are established between the wireless access node and the wireless terminal. Signaling data on the first signaling data path is relayed by a wireless relay node.
Claims12
A wireless access node of a radio access network (RAN) that communicates over a radio interface with a wireless terminal, the wireless access node comprising:
- transmitter circuitry configured to transmit at least one reconfiguration message to the wireless terminal, the at least one reconfiguration message being configured to facilitate dual connectivity (DC) with a first connection and a second connection;
- processor circuitry configured to establish the first connection and the second connection with the wireless terminal, the first connection being relayed by a wireless relay node;
- and
- receiver circuitry configured to receive a failure information message from the wireless terminal via the second connection,
- wherein the failure information message comprises information based on a notification message transmitted from the wireless relay node to the wireless terminal.
A method in a radio access network (RAN) that communicates over a radio interface with a wireless terminal, the method comprising:
- transmitting at least one reconfiguration message to the wireless terminal, the at least one reconfiguration message configured to facilitate dual connectivity (DC) with a first connection and a second connection;
- establishing the first connection and the second connection with the wireless terminal, the first connection being relayed by a wireless relay node;
- and
- receiving a failure information message from the wireless terminal via the second connection,
- wherein the failure information message comprises information based on a notification message transmitted from the wireless relay node to the wireless terminal.
A wireless terminal that communicates over a radio interface with a wireless access node of a radio access network (RAN), the wireless terminal comprising:
- first receiver circuitry configured to receive at least one reconfiguration message from the wireless access node, the at least one reconfiguration message being configured to facilitate dual connectivity (DC) with a first connection and a second connection;
- processor circuitry configured to establish the first connection and the second connection with the wireless access node, the first connection being relayed by a wireless relay node;
- second receiver circuitry configured to receive a notification message from the wireless relay node;
- and
- transmitter circuitry configured to transmit, based on a reception of the notification message, a failure information message to the wireless access node via the second connection.
