Abstract
Apparatus, methods and procedures are provided to handle congestion via access restrictions, e.g., access barring or cell barring, in a wireless relay network. Apparatus, methods, and procedures are also provided to notify nodes and terminals of an IAB-based relay network when some contents of the essential information change.
Claims18
A wireless access node of a radio access network (RAN), the wireless access node comprising:
- transmitter circuitry configured to transmit system information comprising first information and second information, the first information being used for a user equipment (UE) and a relay node, the second information being dedicated to the relay node;
- processor circuitry configured to generate a notification message upon at least one change is made on the system information;
- the transmitter circuitry configured to transmit the notification message;
- wherein
- the notification message indicates the at least one change is made on either or both of the first information and the second information.
A relay node of a radio access network (RAN), the relay node comprising:
- receiver circuitry configured to receive:
- system information comprising first information and second information, the first information being used for a user equipment (UE) and a relay node, the second information being dedicated to the relay node;
- a notification message indicating at least one change is made on either or both of the first information and the second information;
- and
- processor circuitry configured to determine whether or not to (re)acquire the system information based on the notification message.
A user equipment (UE) of a radio access network (RAN), the UE comprising,
- receiver circuitry configured to receive:
- system information comprising first information and second information, the first information being used for a user equipment (UE) and a relay node, the second information being dedicated to the relay node;
- a notification message indicating at least one change is made on either or both of the first information and the second information;
- and
- processor circuitry configured to determine whether or not to (re)acquire the system information based on the notification message.
A method for a wireless access node of a radio access network (RAN), the method comprising,
- transmitting system information comprising first information and second information, the first information being used for a user equipment (UE) and a relay node, the second information being dedicated to the relay node;
- generating a notification message upon at least one change is made on the system information;
- transmitting the notification message;
- wherein
- the notification message indicates the change is made on either or both of the first information and the second information.
A method for a relay node of a radio access network (RAN), the method comprising,
- receiving:
- system information comprising first information and second information, the first information being used for a user equipment (UE) and a relay node, the second information being dedicated to the relay node;
- a notification message indicating at least one change is made on either or both of the first information and the second information;
- and
- determining whether or not to (re)acquire the system information based on the notification message.
A method for a user equipment (UE) of a radio access network (RAN), the method comprising,
- receiving:
- system information comprising first information and second information, the first information being used for a user equipment (UE) and a relay node, the second information being dedicated to the relay node;
- a notification message indicating at least one change is made on either or both of the first information and the second information;
- and
- determining whether or not to (re)acquire the system information based on the notification message.
