AI Technical Summary

Technical Problem

The existing SBP termination frame is not applicable in multi-link scenarios, which makes it impossible for multi-link devices to efficiently establish sensing and measurement sessions, affecting the efficiency of subsequent processes.

Method used

Generate and send an SBP termination frame containing first or second indication information to indicate the reason why the SBP response end and the sensing response end cannot establish a sensing measurement session or the reason for session termination, and negotiate parameters such as required links or the number of links to improve process efficiency.

Benefits of technology

By clarifying the causes and analyzing them, the SBP initiator was able to adjust its strategy, which improved the efficiency of establishing multi-link awareness measurement sessions and reduced signaling overhead and time.

Abstract

The invention provides a communication method, and the method can be applied to supporting an IEEE (Institute of Electrical and Electronic Engineers) protocol, such as an 802.11 be / Wi-Fi (Wireless Fidelity) 7 / Wi-Fi 8 protocol, an IEEE 802.11 Integrated mmWave protocol, an IEEE 802.11 bf / sensing / sensing protocol, or an IEEE 802.15 / UWB (Ultra Wideband) protocol. The method can also support a star flash / spark link protocol. The method comprises: generating an SBP termination frame, the SBP termination frame comprising first indication information or second indication information, the first indication information being used for indicating a reason that a sensing measurement session cannot be established between an SBP response end and a sensing response end, and the second indication information being used for indicating a reason that the sensing measurement session established between the SBP response end and the sensing response end is terminated; sending an SBP termination frame; and the efficiency of subsequently establishing the SBP process can be improved.
