Abstract
A groupcast communication method is applied in a sidelink unlicensed spectrum (Sidelink-U) scenario and performed by a first terminal. The method includes: determining a hybrid automatic repeat request (HARQ) feedback mode selected by the first terminal; and determining whether to retransmit groupcast data according to the HARQ feedback mode selected by the first terminal.
Claims22
A groupcast communication method, applied in a sidelink unlicensed spectrum (Sidelink-U) scenario and performed by a first terminal, comprising:
- determining a hybrid automatic repeat request (HARQ) feedback mode selected by the first terminal;
- and
- determining whether to retransmit groupcast data according to the HARQ feedback mode selected by the first terminal.
A groupcast communication method, applied in a sidelink unlicensed spectrum (Sidelink-U) scenario and performed by a network device, comprising:
- configuring a physical uplink control channel (PUCCH) resource for a first terminal, wherein the PUCCH resource is used to transmit hybrid automatic repeat request (HARQ) feedback information fed back by the first terminal to the network device, and the first terminal is a terminal for sending groupcast data;
- and
- receiving the HARQ feedback information fed back by the first terminal on the PUCCH resource.
