Abstract
A method and an apparatus for improving reliability of multicast broadcast service (MBS) service, a terminal device, and a network device are provided. The method includes the following. A terminal device determines a transmission mode of an MBS service. The terminal device determines, based on the transmission mode of the MBS service, whether a first transmission is new transmission or is retransmission.
Claims12
A method for improving reliability of multicast broadcast service (MBS) service, comprising:
- determining, by a network device, that a transmission mode of an MBS service is:
- new transmission is transmitted in a point to multipoint (PTM) mode, and retransmission is transmitted in a point to point (PTP) mode;
- and
- scheduling, by the network device, transmission of the MBS service based on the transmission mode of the MBS service, comprising:
- scheduling, by the network device, new transmission of first service data in the PTM mode, wherein the first service data is service data of the MBS service;
- and/or
- scheduling, by the network device, retransmission of the first service data in the PTP mode,
- wherein scheduling, by the network device, new transmission of the first service data in the PTM mode comprises:
- sending, by the network device, first downlink (DL) scheduling information scrambled by a group radio network temporary identity (G-RNTI), wherein the first DL scheduling information is used for scheduling new transmission of the first service data, and the first DL scheduling information carries a first hybrid automatic repeat request (HARQ) process identity (ID).
6 more elements
A network device, comprising:
- a transceiver;
- a processor;
- and
- a memory storing computer programs which, when executed by the processor, are operable with the processor to:
- determine that a transmission mode of a multicast broadcast service (MBS) service is:
- new transmission is transmitted in a point to multipoint (PTM) mode, and retransmission is transmitted in a point to point (PTP) mode;
- and
- schedule transmission of the MBS service based on the transmission mode of the MBS service, wherein the processor is configured to:
- schedule new transmission of first service data in the PTM mode, wherein the first service data is service data of the MBS service;
- and/or schedule retransmission of the first service data in the PTP mode;
- wherein the processor configured to schedule new transmission of the first service data in the PTM mode is configured to:
- cause the transceiver to send first downlink (DL) scheduling information scrambled by a group radio network temporary identity (G-RNTI), wherein the first DL scheduling information is used for scheduling new transmission of the first service data, and the first DL scheduling information carries a first hybrid automatic repeat request (HARQ) process identity (ID).
