Method and apparatus for guided adaptive spatial reuse in wireless communication

A method of wireless communication, comprising:

• receiving, by a processing circuit in a device, guiding information for spatial re-use that is carried by a wireless signal transmitted from another device in a present service set with the device, the guiding information including a range of a signal preamble detection threshold or a reference value of a transmit power level for performing transmission by the apparatus;
• receiving power information from another service set corresponding to ongoing wireless communication in the another service set;
• determining the transmit power level based on the received power information corresponding to the ongoing wireless communication in the another service set;
• determining the signal preamble detection threshold following the guiding information and based on the determined transmit power level;
• and
• controlling a transceiver in the device based on the determined signal preamble detection threshold and the determined transmit power level to control the transmission concurrently with the ongoing wireless communication in the another service set,
• wherein the signal preamble detection threshold is used to discard received signals from at least one service set that is different from the present service set and with a strength below the signal preamble detection threshold.

A non-transitory computer readable medium storing program instructions for causing a processor in a device to execute operations for wireless communication, the operations comprising:

• receiving guiding information for spatial re-use that is carried by a wireless signal transmitted from another device in a present service set with the device, the guiding information including a range of a signal preamble detection threshold or a reference value of a transmit power level for performing transmission by the apparatus;
• receiving power information from another service set corresponding to ongoing wireless communication in the another service set;
• determining the transmit power level based on the received power information corresponding to the ongoing wireless communication in the another service set;
• determining the signal preamble detection threshold following the guiding information and based on the determined transmit power level;
• and
• controlling a transceiver in the device based on the determined signal preamble detection threshold and the determined transmit power level to control the transmission concurrently with the ongoing wireless communication in the another service set,
• wherein the signal preamble detection threshold is used to discard received signals from at least one service set that is different from the present service set and with a strength below the signal preamble detection threshold.
