Abstract
A multi-channel transmission method of a V2X communication apparatus is disclosed. A multi-channel transmission method of a V2X communication apparatus according to an embodiment of the present disclosure includes acquiring CBR values for each of a plurality of channels; setting a CBR threshold on the basis of the CBR values; selecting a channel candidate group on the basis of the CBR threshold; and transmitting data through a channel included in the channel candidate group.
Claims11
A multi-channel transmission method of a communication apparatus, comprising:
- acquiring CBR (channel busy ratio) values for each of a plurality of channels;
- setting a CBR threshold based on the CBR values;
- selecting a channel candidate group based on the CBR threshold, and
- transmitting data through a channel included in the channel candidate group,
- wherein the CBR threshold is related to an average value of the CBR values for each of the plurality of channels, and
- wherein based on multi-hop transmission of the data a channel once used for transmitting data is restricted from being used again for a predetermined period, and a channel change is restricted during hopping.

A communication apparatus comprising:
- a memory configured to store data;
- a transmitter and a receiver configured to transmit and receive radio signals;
- and
- a processor configured to control the memory and the transmitter and receiver,
- wherein the processor is further configured to:
- acquire CBR (channel busy ratio) values, one for each of a plurality of channels,
- set a CBR threshold based on the CBR values,
- select a channel candidate group based on the CBR threshold, and
- transmit data through a channel included in the channel candidate group,
- wherein the CBR threshold is related to an average value of the CBR values for each of the plurality of channels,
- wherein based on multi-hop transmission of the data a channel once used for transmitting data is restricted from being used again for a predetermined period, and a channel change is restricted during hopping.
