Load balancing method and related wireless communication device

A wireless communication device, comprising:

• a wireless module, for receiving information sent by at least one neighbor wireless
• communication device, the wireless module comprising:
• an omni antenna;
• and
• a directional antenna;
• a positioning unit, for confirming a location of the wireless communication device;
• and
• a processing unit, for checking a total loading of the wireless communication device and adjusting transmission power of the omni antenna and the directional antenna according to the total loading of the wireless communication device and information sent by the at least one neighbor wireless communication device in order to perform load balancing, wherein the total loading comprises a first loading of the omni antenna and a second loading of the directional antenna;
• wherein the processing unit adjusting the transmission power of the omni antenna and the directional antenna according to the total loading of the wireless communication device in order to perform load balancing comprises:
• the directional antenna reducing power of the directional antenna when the processing unit determining the total loading is greater than a first value;
• the directional antenna sending location information of the wireless communication device and an assistance request to the at least one neighbor wireless communication device when the processing unit determining the first loading is greater than a second value;
• and
• the omni antenna reducing power of the omni antenna when the processing unit determining the first loading is greater than a third value.
