Abstract
An information processing device includes an acquisition unit that acquires information about sidelink communication, and 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 amongst broadcast, groupcast, and unicast;
- determine, based on the acquired sidelink information, whether to enable or disable feedback related to Hybrid Automatic Repeat reQuest (HARQ) for the sidelink communication;
- control the radio transceiver to transmit a first determination result on a Physical Sidelink Shared Channel (PSSCH) in a case where the feedback for the sidelink communication is determined to be enabled, wherein
- the first determination result indicates that the feedback for the sidelink communication is enabled;
- control the radio transceiver to transmit a second determination result on the PSSCH in a case where the feedback for the sidelink communication is determined to be disabled, wherein
- the second determination result indicates that the feedback for the sidelink communication is disabled;
- and
- classify, in a case where the acquired sidelink information indicates the groupcast, a plurality of second user equipments that receives the sidelink communication to a first group for which the feedback is enabled and to a second group for which the feedback is disabled.
