Abstract
Disclosed are example embodiments of methods, apparatuses and systems supporting beam diversity for multimedia broadcast multicast services. A method may comprise receiving information of one or more beams and abeam-specific repetition pattern for at least one of the one or more beams for transmission of a service from a network device, and receiving the service on the at least one of the one or more beams based on the beam-specific repetition pattern.
Claims15
A terminal device comprising:
- at least one processor;
- and
- at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the terminal device to:
- receive information of one or more beams and a beam-specific repetition pattern for at least one of the one or more beams for transmission of a service from a network device;
- and
- receive the service on the at least one of the one or more beams based on the beam-specific repetition pattern;
- wherein receiving information of one or more beams and a beam-specific repetition pattern for at least one of the one or more beams comprises:
- receiving the information of one or more beams carried in a multicast broadcast system information block or a multicast control channel message;
- and receiving the beam-specific repetition pattern on the at least one of the one or more beams;
- and
- wherein the beam-specific repetition pattern is received in a downlink control information message on a group common physical downlink control channel.

A network device comprising:
- at least one processor;
- and
- at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the network device to:
- receive channel state information from one or more terminal devices;
- determine, based on the channel state information, one or more beams and a beam-specific repetition pattern for the respective one or more beams for transmission of a service to the one or more terminal devices;
- indicate the one or more beams and the beam-specific repetition pattern to the one or more terminal devices;
- and
- transmit the service on the one or more beams using the beam-specific repetition pattern;
- wherein indicating the one or more beams and the beam-specific repetition pattern to the one or more terminal devices comprises:
- transmitting information of the one or more beams in a multicast broadcast system information block or a multicast control channel message;
- and
- transmitting the beam-specific repetition pattern on the respective one or more beams;
- and
- wherein the beam-specific repetition pattern is transmitted in a downlink control information message on a group common physical downlink control channel.
