Wireless communication method and wireless communication device

Abstract

The invention discloses a wireless communication method and a wireless communication device, which belong to the field of wireless communication. An access point transmits a downlink control signal toa station associated with the access point, and the station receives the downlink control signal from the access point associated with the station, wherein the downlink control signal includes data of the maximum allowable sleep time corresponding to the station; and a wake-up receiver wakes up the station when the sleep time of the station reaches the maximum allowable sleep time. Thus, the dataof the maximum allowable sleep time can be transmitted to the station through the downlink control signal, the station thus ends sleep when the sleep time reaches the maximum allowable sleep time, the station can thus be prevented from being in a sleep state that is neither waked up nor detectable by any other access point, the occurrences of station disconnection can thus be reduced or avoided,the reliability of the wireless communication system is enhanced, and a low-energy consumption Internet of Things architecture can be realized.

Description

technical field [0001] The present application relates to the field of wireless communication, in particular to a wireless communication method and a wireless communication device. Background technique [0002] Short-range wireless communication technology (such as based on IEEE802.11a, IEEE802.11b, Bluetooth, Bluetooth Low Energy (BLE) or cellular telecommunication standards such as 3GPP Long Term Evolution (LTE) and LTE Evolution (LTE-A), etc.) is used to realize Communications between fixed and portable devices are becoming more and more common, providing low-power, low-cost, high-bandwidth communications to a large number of users. Among them, the feature of low energy consumption has gradually aroused extensive discussions in the industry. Especially for the development requirements of the Internet of Things (IoT) based on the short-distance wireless communication technology, the feature of low energy consumption is particularly important. In this context, the sleep m...

Problems solved by technology

[0004] However, there is a defect in the above-mentioned sleep mechanism that easily causes STAs to lose connection: if a STA moves out of the communication range of its associated AP during the sleep period, the wake-up command sent by the AP cannot reach the STA

Moreover, since the destination addresses of the wake-up instructions sent by other APs do not point to the STA, the STA cannot be woken up.
