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.
Claims21
A first user equipment, comprising:
- a radio transceiver;
- and
- circuitry configured to:
- acquire sidelink information that includes information indicating a communication method of sidelink communication selected from among a broadcast, a groupcast, and a unicast;
- determine to enable or disable feedback associated with Hybrid Automatic Repeat reQuest (HARQ) for the sidelink communication;
- control, based on the determination that the feedback is enabled for the sidelink communication, the radio transceiver to transmit a first determination result on a Physical Sidelink Shared Channel (PSSCH), wherein the first determination result indicates that the feedback for the sidelink communication is enabled;
- control, based on the determination that the feedback is disabled for the sidelink communication, the radio transceiver to transmit a second determination result on the PSSCH, wherein the second determination result indicates that the feedback for the sidelink communication is disabled;
- and
- control, based on the acquired sidelink information that indicates the groupcast, the radio transceiver to execute the sidelink communication with the feedback, wherein the execution of the sidelink communication is based on a number of second user equipments in a group for the groupcast.

A method, comprising:
- acquiring sidelink information that includes information indicating a communication method of sidelink communication selected from among a broadcast, a groupcast, and a unicast;
- determining to enable or disable feedback associated with Hybrid Automatic Repeat reQuest (HARQ) for the sidelink communication;
- transmitting, based on the determination that the feedback is enabled for the sidelink communication, a first determination result on a Physical Sidelink Shared Channel (PSSCH), wherein the first determination result indicates that the feedback for the sidelink communication is enabled;
- transmitting, based on the determination that the feedback for the sidelink communication is disabled, a second determination result on the PSSCH, wherein the second determination result indicates that the feedback for the sidelink communication is disabled;
- and
- executing, based on the acquired sidelink information indicates the groupcast, the sidelink communication with the feedback, wherein the execution of the sidelink communication is based on a number of user equipments in a group for the groupcast.
