Wireless access point and station applied in wireless communication system and communication method

A station applied in a wireless communication system, comprising:

• a memory, configured to store at least one instruction;
• a communication module;
• and
• a processor, coupled to the memory and the communication module, and configured to access and execute the at least one instruction for:
• receiving a plurality of beacons transmitted by a wireless access point in the wireless communication system, and enabling the station to be in a low power sleep mode or an active mode according to the beacons, wherein the beacons include a first beacon and a neighboring second beacon;
• between receiving the first beacon and receiving the second beacon, determining whether a management frame is received from the wireless access point station, wherein the wireless access point determines whether to transmit the management frame according to a traffic condition of at least one packet being directed to the station, the traffic condition includes a channel state and a number or a validity of the at least one packet;
• and
• in response to the management frame, switching from the low power sleep mode to the active mode or from the active mode to the low power sleep mode,
• wherein the processor is further configured to access and execute the at least one instruction for:
• determining whether at least one of the beacons includes a confirmation message, wherein the confirmation message is used by the wireless access point to confirm whether the station supports a reception of the management frame;
• and
• sending, by the communication module, a acknowledge message to the confirmation message to enable the wireless access point to transmit the management frame according to the traffic conditions.

A communication method, used in a wireless access point and a station, wherein the communication method comprising:

• the wireless access point periodically transmitting a plurality of beacons to the station, so that the station is in an low power sleep mode or an active mode according to the beacons, wherein the beacons include a first beacon and a second beacon transmitted sequentially;
• between transmitting the first beacon and transmitting the second beacon, the wireless access point determining whether to transmit a management frame to the station based on a traffic condition of at least one packet being directed to the station, wherein the traffic condition includes a number or a validity of the at least one packet;
• and
• the station switches from the low power sleep mode to the active mode or from the active mode to the low power sleep mode in response to the management frame,
• wherein the communication method further comprises:
• the wireless access point transmitting at least one of the beacons which includes a confirmation message configured to confirm whether the station supports receiving the management frame;
• and
• if the station responds to the confirmation message with a acknowledge message to the wireless access point, the wireless access point transmitting the management frame to the station according to the traffic condition.
