Abstract
The present invention provides a wireless communication method, wherein the wireless communication method includes the steps of: controlling the electronic device to operate in an active mode and communicating with an access point; after a traffic between the electronic device and the access point ends, controlling the electronic device to operate in a first mode, and transmitting a null frame to notify the access point that the electronic device enters a power saving mode; and during the first mode, controlling the electronic device to leave the power saving mode and transmitting at least one query signal to the access point to ask data.
Claims20
A wireless communication method of an electronic device, comprising:
- controlling the electronic device to operate in an active mode and communicating with an access point;
- after a traffic between the electronic device and the access point ends, controlling the electronic device to operate in a first mode, and transmitting a null frame to notify the access point that the electronic device enters a power saving mode;
- and
- during the first mode, controlling the electronic device to leave the power saving mode and transmitting at least one query signal to the access point to ask data;
- wherein the step of during the first mode, controlling the electronic device to leave the power saving mode and transmitting the at least one query signal to the access point to ask data comprises:
- selecting one of a plurality of configurations, wherein the plurality of configurations correspond to different number of query signals and/or different intervals between two adjacent query signals;
- and
- using the selected configuration to control the electronic device to transmit the at least one query signal to the access point to ask data.
An electronic device comprising a processing circuit and a wireless communication circuit, wherein the wireless communication circuit is configured to perform the steps of:
- controlling the electronic device to operate in an active mode and communicating with an access point;
- after a traffic between the electronic device and the access point ends, controlling the electronic device to operate in a first mode, and transmitting a null frame to notify the access point that the electronic device enters a power saving mode;
- and
- during the first mode, controlling the electronic device to leave the power saving mode and transmitting at least one query signal to the access point to ask data;
- wherein the step of during the first mode, controlling the electronic device to leave the power saving mode and transmitting the at least one query signal to the access point to ask data comprises:
- selecting one of a plurality of configurations, wherein the plurality of configurations correspond to different number of query signals and/or different intervals between two adjacent query signals;
- and
- using the selected configuration to control the electronic device to transmit the at least one query signal to the access point to ask data.
