Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a communication method of a wireless local area network, a communication apparatus of a wireless local area network, an access point device, and a station device.
Background
In the year 2016, 7, IEEE (Institute of Electrical and Electronics Engineers) 802.11 established the research group WUR (wake Up receiver) of the next generation Wi-Fi (Wireless Fidelity) technology, which is IEEE 802.11ba, and is mainly applied to the internet of things, in order to save the power consumption of the device as much as possible, and most importantly, in order to make the device receiving the wake-Up frame (wake Up message frame, i.e., WUR message frame) save the power consumption of the device as much as possible, wherein the power consumption required by the device to receive the wake-Up frame is not more than 1 mW.
When the device is in the WUR mode, the primary communication interface of the device is in a sleep state, and the secondary communication interface of the device is in a continuous awake state or a periodic awake state, where the secondary communication interface is used to receive a WUR message frame sent by an AP (Access Point), so as to wake up the primary communication interface to obtain a downlink data frame cached by the AP for the device.
In the standard formulation process, it is specified for a station device to be in both a PS (Power Saving) mode and a WUR mode, if the station device is in the WUR mode, that:
(1) if the main communication interface of the station equipment is in a dormant state, WURX (wake Up receiver) of the station equipment follows the scheduled work period between the access point equipment and the station equipment, and comprises WURX in a continuous awakening state.
(2) For primary communication channel pcr (primary Connectivity radio) scheduling of a station device (for example, a scheduling target Wake time twt (target Wake time) of a wireless Network management wnm (wireless Network management)), a Service Period (SP) currently negotiated between an access point device and the station device is suspended, specifically: if the service period is suspended, the station device does not need to be woken up during the service period; the parameters of the negotiated service period scheduled for the PCR of the station device are still retained by the access point device and the station device when the negotiated service period is suspended.
In summary, that is to say, for an SP negotiated by the station device and the access point device in the primary communication channel, if the station device enters the WUR mode, the SP will be suspended, but when the secondary communication interface of the station device receives a wake-up message frame from the access point device to put the primary communication interface of the station device in a wake-up state, how to handle the suspended SP is not explicitly specified in the standard.
