Abstract
The disclosure relates to a wireless local area network (WLAN) system. A method and an apparatus for transferring target wake time (TWT) bandwidth information to effectively operate the TWT, and performing frequency division coordinated TWT (C-TWT) between access points (APs) are provided.
Claims14
A method performed by a first electronic device in a wireless local area network (LAN) network, the method comprising:
- receiving a target wake time (TWT)-related frame comprising TWT bandwidth information from a second electronic device;
- occupying a transmission opportunity (TXOP);
- identifying whether a frequency band of a TWT service period (SP) corresponding to the TWT-related frame, which is to start during occupation of the TXOP, overlaps at least partially with a frequency band of the TXOP;
- and
- terminating the TXOP in case that the frequency band of the TWT SP and the frequency band of the TXOP overlap at least partially,
- wherein the frequency band of the TWT SP is identified based on the TWT bandwidth information.
A method performed by a second electronic device in a wireless local area network (LAN) network, the method comprising:
- transmitting a target wake time (TWT)-related frame comprising TWT bandwidth information to a first electronic device;
- and
- transmitting and receiving a frame in a TWT service period (SP) corresponding to the TWT-related frame.
A first electronic device in a wireless local area network (LAN) network, the first electronic device comprising:
- a transceiver;
- and
- a controller communicatively coupled to the transceiver and configured to:
- receive a target wake time (TWT)-related frame comprising TWT bandwidth information from a second electronic device,
- occupy a transmission opportunity (TXOP),
- identify whether a frequency band of a TWT service period (SP) corresponding to the TWT-related frame, which is to start during occupation of the TXOP, overlaps at least partially with a frequency band of the TXOP, and
- terminate the TXOP in case that the frequency band of the TWT SP and the frequency band of the TXOP overlap at least partially,
- wherein the frequency band of the TWT SP is identified based on the TWT bandwidth information.
A second electronic device of a wireless local area network (LAN) network, the second electronic device comprising:
- a transceiver;
- and
- a controller communicatively coupled to the transceiver and configured to:
- transmit a target wake time (TWT)-related frame comprising TWT bandwidth information to a first electronic device, and
- transmit and receive a frame in a TWT service period (SP) corresponding to the TWT-related frame.
