Terminal and communication method for resource reservation in vehicle to everything (V2X) communication
A terminal includes a receiver that receives, from another terminal, information that is related to inter-terminal direct communication and is for identifying available resources; a controller that identifies candidate resources and selects a resource to be used, based on the information; and a transmitter that performs transmission in the inter-terminal direct communication using the selected resource.
1 . A terminal comprising:
a receiver that receives, from a first terminal, control information via a control channel; and
a transmitter that transmits, to a second terminal, information for avoiding a collision between a first resource and a second resource,
wherein the first resource is indicated by the control information and used by the first terminal for transmission of a shared channel,
wherein the second resource is used by the second terminal for transmission of the shared channel,
wherein the transmitter transmits, to the second terminal, the information for avoiding the collision in a transmission opportunity for a feedback channel corresponding to a reception slot of the control information via the control channel, and
wherein the transmitter transmits, to the second terminal, the information for avoiding the collision in a transmission opportunity for a feedback channel corresponding to the first resource indicated by the control information.
2 . A communication method performed by a terminal, the communication method comprising:
receiving, from a first terminal, control information via a control channel; and
transmitting, to a second terminal, information for avoiding a collision between a first resource and a second resource,
wherein the first resource is indicated by the control information and used by the first terminal for transmission of a shared channel,
wherein the second resource is used by the second terminal for transmission of the shared channel,
wherein the transmitting transmits, to the second terminal, the information for avoiding the collision in a transmission opportunity for a feedback channel corresponding to a reception slot of the control information via the control channel, and
wherein the information for avoiding the collision is transmitted, to the second terminal, in a transmission opportunity for a feedback channel corresponding to the first resource indicated by the control information.
