[0122] The UHR technology aims to improve the reliability of wireless local area network connection, reduce the delay and reduce the device level power consumption, and further enhance the power saving mechanism, researchers propose a new power management method. That is, a wireless device (such as an access point device or a station device) can work in a low-capability mode, and in the low-capability mode, the wireless device can receive a specific wireless frame, such as an initial control frame. That is, when a wireless device (a first wireless device) works in a low-capability mode, another wireless device (a second wireless device) associated with it can send an initial control frame to the first wireless device, so that after the first wireless device receives the initial control frame, it switches to a higher capability mode to exchange frames with the second wireless device.

[0123] The above method can effectively reduce the energy consumption of the wireless device to a certain extent and ensure the timely and effective transmission of wireless data. However, the above method still has many problems. For example, after the first wireless device working in the low-capability mode receives the initial control frame sent by the associated second wireless device, it needs to switch to the high-capability mode to complete the frame exchange. If the capability parameter of the first wireless device in the high-capability mode after switching is too small, for example, when the channel bandwidth of the first wireless frame after completing the capability mode switching is less than the channel bandwidth of the uplink data frame sent by the second wireless device or the maximum spatial stream number supporting the reception of the data frame is less than the spatial stream number of the uplink data frame sent by the second wireless device, the frame exchange between the first wireless device and the second wireless device will not be able to proceed.

[0124] In order to solve the above problems, the technical solutions in the embodiments of the present disclosure will be further described clearly and completely in combination with the drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, and not all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present disclosure.
