Data unit processing method and communication device applying the data unit processing method

A data unit processing method performed by a communication device, for processing a data unit comprising a specific format preamble following a first packet format and comprising a symbol part with at least one symbol following a Wi-Fi long range packet format, comprising:

• (a) processing the specific format preamble to determine a length of the symbol part and determining whether the symbol part follows the first packet format or follows the Wi-Fi long range packet format according to identifying information contained in the symbol part;
• (b) applying a first communication standard to decode the symbol part when the symbol part follows the first packet format;
• and
• (c) applying a Wi-Fi long range mode to process the symbol part when the symbol part follows the Wi-Fi long range packet format.

A communication device, comprising:

• a control circuit, configured to execute program codes stored in a storage device to configure a data unit comprising:
• a specific format preamble following a first packet format;
• and
• a symbol part, comprising at least one symbol and following a Wi-Fi long range packet format;
• wherein the specific format preamble can be processed according to a first communication standard and the symbol can be processed according to a Wi-Fi long range mode;
• wherein a length of the symbol part can be determined according to the specific format preamble and the symbol part can be identified according identifying information in the symbol part.
