Abstract
Communication methods and devices include opening a plurality of detection windows according to a preset detection period; in response to having detected a preamble of a radio frame in at least a preset number of continuous detection windows of the plurality of detection windows, switching the receiving end device to an awake state; and receiving the radio frame while the receiving end device is operating in the awake state.
Claims12
A communication method performed by a receiving end device, comprising:
- opening a plurality of first detection windows according to a preset first detection period;
- and
- continuously opening a preset first number of second detection windows according to a preset first time interval after opening one of the first detection windows and before opening a next one of the first detection windows, wherein a duration of each of the first detection windows is the same as a duration of each of the second detection windows;
- in response to having detected a long preamble of a radio frame in at least a preset second number of consecutive second detection windows, switching the receiving end device to an awake state;
- and
- receiving the radio frame while the receiving end device is operating in the awake state.
A communication apparatus, comprising:
- a memory storing a set of instructions;
- and
- one or more processors configured to execute the set of instructions to cause the apparatus to perform:
- opening a plurality of first detection windows according to a preset first detection period;
- and
- continuously opening a preset first number of second detection windows according to a preset first time interval after opening one of the first detection windows and before opening a next one of the first detection windows, wherein a duration of each of the first detection windows is the same as a duration of each of the second detection windows;
- in response to having detected a long preamble of a radio frame in at least a preset second number of consecutive second detection windows, switching the apparatus to an awake state;
- and
- receiving the radio frame while the apparatus is operating in the awake state.
A non-transitory computer readable medium that stores a set of instructions that is executable by at least one processor of a computer to cause the computer to perform a communication method, the method comprising:
- opening a plurality of first detection windows according to a preset first detection period;
- and
- continuously opening a preset first number of second detection windows according to a preset first time interval after opening one of the first detection windows and before opening a next one of the first detection windows, wherein a duration of each of the first detection windows is the same as a duration of each of the second detection windows;
- in response to having detected a long preamble of a radio frame in at least a preset second number of consecutive second detection windows, switching the computer to an awake state;
- and
- receiving the radio frame while the computer is operating in the awake state.
