Communication control method
A communication control method is a method using a relay user equipment relaying communication between a base station and a remote user equipment. The communication control method includes establishing a connection between the remote user equipment and the relay user equipment, and performing a random access procedure establishing a connection between the remote user equipment and the base station. The performing the random access procedure includes a proxy operation where the relay user equipment, instead of the remote user equipment, performs at least a part of an operation to be performed by a Medium Access Control (MAC) layer in the random access procedure.
1 . A communication control method using a relay user equipment configured to relay communication between a base station and a remote user equipment, the communication control method comprising:
receiving, by the remote user equipment, a Radio Resource Control (RRC) release message from the base station via the relay user equipment; and
after completion of releasing or suspending a RRC connection between the remote user equipment and the base station in response to reception of the RRC release message, performing, by the remote user equipment, a notification operation configured to notify the relay user equipment of a content of the RRC release message received from the relay user equipment.
2 . A remote user equipment configured to perform communication between a base station via a relay user equipment, the remote user equipment comprising:
a receiver configured to receive a Radio Resource Control (RRC) release message from the base station via the relay user equipment; and
a transmitter configured to, after completion of releasing or suspending a RRC connection between the remote user equipment and the base station in response to reception of the RRC release message, notify the relay user equipment of a content of the RRC release message received from the relay user equipment.
3 . An apparatus configured to control a remote user equipment configured to perform communication between a base station via a relay user equipment, the apparatus comprising
a processor and a memory, the apparatus configured to receive a Radio Resource Control (RRC) release message from the base station via the relay user equipment, and
after completion of releasing or suspending a RRC connection between the remote user equipment and the base station in response to reception of the RRC release message, notify the relay user equipment of a content of the RRC release message received from the relay user equipment.
