Problems solved by technology

However, packets for long-range Wi-Fi systems follow a different packet format than traditional Wi-Fi systems
Therefore, when a Wi-Fi long-range packet arrives at a legacy Wi-Fi system, the legacy Wi-Fi system cannot recognize the Wi-Fi long-range packet and cannot successfully decode the Wi-Fi long-range packet
[0003] Therefore, the hardware of the conventional Wi-Fi system is independent from the hardware of the conventional long-range Wi-Fi system, which increases the cost of the wireless communication system and brings inconvenience to users

Embodiment Construction

[0019] Certain terms are used in the description and claims to refer to particular components. Those skilled in the art should understand that manufacturers of electronic equipment may use different terms to refer to the same component. The specification and claims do not use the difference in name as the way to distinguish components, but use the difference in function of the components as the basis for the difference. The "comprising" mentioned throughout the specification and the following claims is an open-ended term, so it should be interpreted as "including but not limited to". In addition, the term "coupled" herein includes any direct and indirect means of electrical connection. Therefore, if it is described herein that a first device is electrically connected to a second device, it means that the first device may be directly connected to the second device, or indirectly connected to the second device through other devices or connection means.

Abstract

A data unit processing method and a communication system are provided. The method is performed by a first communication device, comprising: configuring a data unit by the first communication device, the 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. The specific format preamble can be decoded according to a first communication standard and the symbol part can be processed according to a Wi-Fi long range mode. 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. Through the present invention, a single communication device can receive and process Wi-Fi long-range data packets and Wi-Fi traditional data packets.

Description

technical field [0001] The present invention relates to wireless communication, and more particularly, to a data unit processing method and a communication device in a legacy (legacy) Wi-Fi system and a long-range (longrange) Wi-Fi system. Background technique [0002] Long range (long range) Wi-Fi systems have better sensitivity than legacy (legacy) Wi-Fi systems, so data packets can be transmitted over longer distances. However, the data packet format followed by the data packet of the long-range Wi-Fi system is different from the data packet format of the traditional Wi-Fi system. Therefore, when the Wi-Fi long-range data packet reaches the conventional Wi-Fi system, the conventional Wi-Fi system cannot recognize the Wi-Fi long-range data packet and cannot successfully decode the Wi-Fi long-range data packet. [0003] Therefore, the hardware of the conventional Wi-Fi system is independent of the hardware of the conventional long-range Wi-Fi system, which increases the co...
