Wireless communication apparatus on vehicle and wireless communication method

A wireless communication method performed by the wireless communication apparatus on a vehicle, the wireless communication apparatus includes a first wireless transceiver configured to transmit and receive data on a first communication path, a second wireless transceiver configured to transmit and receive data on a second communication path, and a processor electrically connected to the first wireless transceiver and the second wireless transceiver, the method comprising:

• establishing, as a default mean of communication, multiple communication paths comprising the first communication path on a first channel selected out of a first subset of channels of a first plurality of available channels of the first wireless transceiver and the second communication path on a second channel selected out of a second subset of channels of a second plurality of available channels of the second wireless transceiver;
• transmitting by the first wireless transceiver, as the default mean of communication, a first data packet to the network located outside of the vehicle on the first communication path;
• transmitting by the second wireless transceiver, as the default mean of communication, a first duplicated data packet of the first data packet to the network on the second communication path;
• performing, by the first wireless transceiver, a first handover (HO) procedure at a first time period by selecting, from the first subset of channels, a third channel;
• and
• transmitting, through the third channel, a second data packet on the first communication path in response to completing the first HO, and a second duplicated data packet of the second data packet on the second communication path which remains on the second channel.
