Abstract
A communication control method used in a cellular communication system includes determining, by a remote user equipment having sidelink connection with a relay user equipment, a network communication state between the remote user equipment and a cellular communication network, and performing, by the remote user equipment, control related to sidelink communication between the remote user equipment and the relay user equipment, based on the network communication state.
Claims3
A communication control method used in a cellular communication system, the communication control method comprising:
- detecting, by a relay user equipment having a sidelink connection with a remote user equipment, a Radio Link Failure (RLF) between the relay user equipment and a cellular communication network or between the relay user equipment and another user equipment other than the cellular communication network;
- and
- transmitting, by the relay user equipment, a PC5-RRC message including information indicating the detected RLF to the remote user equipment, the information including a first information element and a second information element for indicating a type of the detected RLF, the first information element configured to indicate that the detected RLF is between the relay user equipment and the cellular communication network, the second information element configured to indicate that the detected RLF is between the relay user equipment and the another user equipment.
A relay user equipment used in a cellular communication system, the relay user equipment comprising
- a controller configured to detect, in a state of the relay user equipment having a sidelink connection with a remote user equipment, Radio Link Failure (RLF) between the relay user equipment and a cellular communication network or between the relay user equipment and another user equipment other than the cellular communication network, and
- a transmitter configured to transmit a PC5-RRC message including information indicating the detected RLF to the remote user equipment, the information including a first information element and a second information element for indicating a type of the detected RLF, the first information element configured to indicate that the detected RLF is between the relay user equipment and the cellular communication network, the second information element configured to indicate that the detected RLF is between the relay user equipment and the another user equipment.
An apparatus for controlling a relay user equipment used in a cellular communication system, the apparatus comprising a processor and a memory coupled to the processor, the processor configured to:
- detect, in a state of the relay user equipment having a sidelink connection with a remote user equipment, Radio Link Failure (RLF) between the relay user equipment and a cellular communication network or between the relay user equipment and another user equipment other than the cellular communication network, and
- transmit a PC5-RRC message including information indicating the detected RLF to the remote user equipment, the information including a first information element and a second information element for indicating a type of the detected RLF, the first information element configured to indicate that the detected RLF is between the relay user equipment and the cellular communication network, the second information element configured to indicate that the detected RLF is between the relay user equipment and the another user equipment.
