Abstract:
1. A method of communication based on battery in a wireless LAN system, the method comprising: receiving, by a station (STA), a battery lifetime request message from an access point (AP), wherein the battery lifetime request message includes a battery lifetime report interval field and battery lifetime report threshold field, the battery lifetime report interval field indicating an interval at which the STA report a battery lifetime, the battery lifetime report threshold field indicating a threshold of the battery lifetime; transmitting, by the STA, a first battery lifetime report message including information indicating a first battery lifetime; receiving, by the STA, a battery lifetime extension management message from the AP, wherein the battery lifetime extension management message includes a duty cycle field indicating a duty cycle and a transmission power limit field indicating a transmission power limit value; and transmitting, by the STA, an extended capabilities information element to the AP, wherein the extended capabilities information element includes a battery lifetime report field indicating whether the STA supports the battery lifetime report and a battery-based operating device field indicating whether the STA is operated based on a battery.
