Abstract
A communication method according to one embodiment is a communication method in which a first radio terminal executes a layer 2 relay in which a packet of a second radio terminal is transmitted between the second radio terminal and a base station in a layer higher than a Radio Link Control (RLC) layer in Layer 2. The first radio terminal transmits information indicating that the first radio terminal is capable of executing the layer 2 relay. The second radio terminal transmits a request for the layer 2 relay to the first radio terminal in response to receiving the information.
Claims4
A communication method in which a first radio terminal executes a layer 2 relay in which a packet of a second radio terminal is transmitted between the second radio terminal and a base station in a layer higher than a Radio Link Control (RLC) layer in Layer 2, the communication method comprising:
- transmitting, by the first radio terminal, information indicating that the first radio terminal is capable of executing the layer 2 relay, the information included in a discovery message for relay;
- and
- directly transmitting, by the second radio terminal, a request for the layer 2 relay to the first radio terminal in response to receiving the information, the request included in a message for requesting direct communication, wherein
- in the layer 2 relay, processing of the packet is executed in a special layer that is a higher layer than the RLC layer and different from a Packet Data Convergence Protocol (PDCP) layer, and
- the base station and the second radio terminal include, into the packet, information indicating that the packet has been processed in the special layer, in a layer lower than the special layer.
A communication method in which a first radio terminal executes a layer 2 relay in which a packet of a second radio terminal is transmitted between the second radio terminal and a base station in a layer higher than a Radio Link Control (RLC) layer in Layer 2, the communication method comprising:
- transmitting, by the first radio terminal, information indicating that the first radio terminal is capable of executing the layer 2 relay, the information included in a discovery message for relay;
- and
- directly transmitting, by the second radio terminal, a request for the layer 2 relay to the first radio terminal in response to receiving the information, the request included in a message for requesting direct communication, wherein
- in the layer 2 relay, processing of the packet is executed in a special layer that is a higher layer than the RLC layer and different from a Packet Data Convergence Protocol (PDCP) layer, and
- the base station notifies the first radio terminal of a logical channel identifier for which a packet is permitted to be transmitted via the special layer.
A first radio terminal configured to execute a layer 2 relay in which a packet of a second radio terminal is transmitted between the second radio terminal and a base station in a layer higher than a Radio Link Control (RLC) layer in Layer 2, the radio terminal comprising:
- a transmitter configured to transmit information indicating that the first radio terminal is capable of executing the layer 2 relay, the information included in a discovery message for relay;
- and
- a receiver configured to directly receive, from the second radio terminal, a request for the layer 2 relay, the request transmitted in response to receiving, by the radio terminal, the information, and the request included in a message for requesting direct communication, wherein
- in the layer 2 relay, processing of the packet is executed in a special layer that is a higher layer than the RLC layer and different from a Packet Data Convergence Protocol (PDCP) layer, and
- the receiver is configured to receive, from the base station, a logical channel identifier for which a packet is permitted to be transmitted via the special layer.
A second radio terminal comprising:
- a receiver configured to receive, from a first radio terminal configured to execute a layer 2 relay in which a packet of the second radio terminal is transmitted between the second radio terminal and a base station in a layer higher than a Radio Link Control (RLC) layer in Layer 2, information indicating that the first radio terminal is capable of executing the layer 2 relay, the information included in a discovery message for relay;
- and
- a transmitter configured to directly transmit a request for the layer 2 relay to the first radio terminal in response to receiving the information, the request included in a message for requesting direct communication, wherein
- in the layer 2 relay, processing of the packet is executed in a special layer that is a higher layer than the RLC layer and different from a Packet Data Convergence Protocol (PDCP) layer, and
- the second radio terminal further comprises a controller configured to include, into the packet, information indicating that the packet has been processed in the special layer, in a layer lower than the special layer.
