Abstract
The present invention discloses a broadcast method, an apparatus, and a system. According to a solution provided in embodiments of the present invention, a broadcast decision apparatus obtains broadcast decision information of a plurality of terminals, where the broadcast decision information includes at least location information of the terminals. The broadcast decision apparatus selects some terminals from the plurality of terminals as relay terminals based on the broadcast decision information and a transmission range of data, and sends configuration information to the relay terminals to indicate the relay terminals to broadcast the data. The solution may be applied to a multi-hop broadcast scenario in vehicle to

A broadcast method, comprising:
- sending, by a first communication apparatus, a first request to a first apparatus, wherein the first request is for requesting to broadcast first data whose transmission range is a first range, and the first communication apparatus is a first terminal or a chip in the first terminal;
- receiving, by the first communication apparatus from the first apparatus, a first response in response to the first request, wherein the first response indicates to broadcast the first data;
- and
- broadcasting, by the first communication apparatus, the first data.
A communication apparatus, comprising at least one processor coupled to a memory, wherein
- the at least one processor is configured to read instructions from the memory, and run the instructions to:
- send a first request to a first apparatus, wherein the first request is for requesting to broadcast first data whose transmission range is a first range, and the communication apparatus is a first terminal or a chip in the first terminal;
- receive, from the first apparatus, a first response in response to the first request, wherein the first response indicates to broadcast the first data;
- and
- broadcast the first data.
A system, comprising:
- a first terminal and a second terminal, wherein the first terminal is configured to:
- send a first request to a first apparatus, wherein the first request is for requesting to broadcast first data whose transmission range is a first range;
- receive, from the first apparatus, a first response in response to the first request, wherein the first response indicates to broadcast the first data;
- and
- broadcast the first data;
- and
- wherein the second terminal is configured to:
- receive the first data;
- broadcast the first data according to configuration information, wherein the configuration information indicates to broadcast the first data whose transmission range is the first range.
