Abstract
Provided is an information processing device that includes an acquisition unit that acquires information about sidelink communication. The information processing device further includes a determination unit that determines whether to enable feedback related to a data automatic repeat request in the sidelink communication based on the information about the sidelink communication.
Claims20
A first user device, comprising:
- a radio transceiver;
- and
- circuitry configured to:
- process sidelink information that includes first information associated with a communication method of sidelink communication selected from among a broadcast, a groupcast, and a unicast;
- determine, based on the first information, second information for configuring a feedback configuration for the sidelink communication;
- and
- control, the radio transceiver to transmit the determined second information to at least one of second user devices on a Physical Sidelink Shared Channel (PSSCH),
- wherein, in a case where the first information indicates that the communication method is the groupcast, the feedback configuration is configured, based on third information associated with a number of second user devices in a group for the groupcast, to be either of:
- (a) a first configuration where transmission of at least an ACK is required when data is successfully received;
- or (b) a second configuration where transmission of ACK is not required when data is successfully received.

A second user device, comprising:
- a radio transceiver;
- and
- circuitry configured to:
- control, the radio transceiver to receive second information to configure a feedback configuration of a sidelink communication on a Physical Sidelink Shared Channel (PSSCH) from a first user device, the second information being generated based on first information associated with a communication method of the sidelink communication selected from among a broadcast, a groupcast, and a unicast,
- control the radio transceiver to execute the sidelink communication based on the feedback configuration such that:
- in a case where the communication method of the sidelink communication is the groupcast and the second user device receives data successfully, whether the second user device transmits at least an ACK or not depends on third information associated with a number of user devices in a group for the groupcast to which the second user device belongs.
3 more elements
A method of configuring a feedback configuration for sidelink communication between a first user device and at least one of second user devices, comprising:
- processing sidelink information that includes first information associated with a communication method of the sidelink communication selected from among a broadcast, a groupcast, and a unicast;
- determining second information for configuring the feedback configuration for the sidelink communication based on the first information;
- and
- controlling, a radio transceiver to transmit the second information to the at least one of second user devices on a Physical Sidelink Shared Channel (PSSCH),
- wherein, in a case where the first information indicates that the communication method is the groupcast, the feedback configuration is configured, based on third information associated with a number of the second user devices in a group for the groupcast, to be either of:
- (a) a first configuration where transmission of at least an ACK is required when data is successfully received;
- or (b) a second configuration where transmission of an ACK is not required when data is successfully received.
