Abstract
Provided is a user equipment including a transmitting unit that transmits a packet for terminal-to-terminal direct communication and a control unit that selects a transmission resource for transmitting the packet from candidate resources in a resource selection window having a predetermined range.
Claims3
A terminal comprising:
- a receiving unit that receives an SCI format from another terminal of terminal-to-terminal direct communication;
- a control unit that selects, as a candidate transmission resource, a resource other than a resource that is determined by the SCI format received from the another terminal, from a resource selection range, the candidate transmission resource being used for data transmission by the terminal-to-terminal direct communication;
- and
- a transmitting unit that transmits an SCI format via a first resource of the selected transmission resource,
- wherein the resource selection range is a range from a slot obtained by adding a first value to a reference slot via which a parameter is received from an upper layer, to a slot obtained by adding a second value to the reference slot, and
- wherein in response to transmission of the resource being stopped, reselecting a resource replacing the stopped resource.

A communication system comprising:
- a terminal;
- and a base station, wherein
- the terminal includes:
- a receiving unit that receives an SCI format from another terminal of terminal-to-terminal direct communication;
- a control unit that selects, as a candidate transmission resource, a resource other than a resource that is determined by the SCI format received from the another terminal, from a resource selection range, the candidate transmission resource being used for data transmission by the terminal-to-terminal direct communication;
- and
- a transmitting unit that transmits an SCI format via a first resource of the selected transmission resource,
- wherein the resource selection range is a range from a slot obtained by adding a first value to a reference slot via which a parameter is received from an upper layer, to a slot obtained by adding a second value to the reference slot, and
- wherein in response to transmission of the resource being stopped, reselecting a resource replacing the stopped resource, and
- the base station includes
- a transmitting unit that transmits the parameter via the upper layer.

A communication method of a terminal, comprising:
- receiving an SCI format from another terminal of terminal-to-terminal direct communication;
- selecting, as a candidate transmission resource, a resource other than a resource that is determined by the SCI format received from the another terminal, from a resource selection range, the candidate transmission resource being used for data transmission by the terminal-to-terminal direct communication;
- and
- transmitting an SCI format via a first resource of the selected transmission resource,
- wherein the resource selection range is a range from a slot obtained by adding a first value to a reference slot via which a parameter is received from an upper layer, to a slot obtained by adding a second value to the reference slot, and
- wherein in response to transmission of the resource being stopped, reselecting a resource replacing the stopped resource.
