CN-121986541-A - Coexistence status information via response messages

Abstract

The present disclosure provides methods, components, devices, and systems for providing information regarding coexistence situations. Some aspects relate more particularly to providing coexistence status information via response messages. In some examples, the coexistence status information provided via the response message may indicate that the wireless communication device is experiencing a coexistence status, may include information regarding the coexistence status, or a combination of both uses. The response message for carrying the coexistence information may include a message that is received in response to a message from the peer wireless communication device via an existing or otherwise previously established messaging channel established for messaging of information other than the coexistence information.

Description

Coexistence status information via response messages Cross Reference to Related Applications The present application claims the benefit of U.S. patent application Ser. No. 18/489,821, entitled "CO-EXISTENCE CONDITION INFORMATION VIA RESPONSE MESSAGE (coexistence information via response message)" filed on month 10 of 2023, which is expressly incorporated herein by reference in its entirety. Technical Field The present disclosure relates generally to wireless communications, and more particularly to providing coexistence status information via response messages. Background A Wireless Local Area Network (WLAN) may be formed of one or more wireless Access Points (APs) that provide a shared wireless communication medium for use by a plurality of client devices, also referred to as wireless Stations (STAs). The basic building block of WLANs conforming to the Institute of Electrical and Electronics Engineers (IEEE) 802.11 family of standards is the Basic Service Set (BSS) managed by an AP. Each BSS is identified by a Basic Service Set Identifier (BSSID) advertised by the AP. The AP periodically broadcasts beacon frames to enable any STA within wireless range of the AP to establish or maintain a communication link with the WLAN. In some WLANs, a wireless communication device (e.g., an AP, STA, or a combination thereof) may perform simultaneous wireless communications for multiple communication sessions. For example, a wireless communication device may utilize multiple wireless communication transmit/receive (Tx/Rx) chains operable to simultaneously perform multiple communication sessions. A wireless communication device implementing WLAN communications according to the Wi-Fi protocol may perform communications simultaneously, e.g., according to one or more of the cellular, ZIGBEE, THREAD, bluetooth, etc. protocols. While the communication session may utilize the same frequency band (e.g., the communications each take place in the same one of the 2.4GHz, 5GHz, 6GHz, or 60GHz frequency bands), or may otherwise utilize frequencies that cause any or all of the multiple wireless communication Tx/Rx chains to experience interference within the wireless communication device (within the device). In some scenarios, although not operating in the same or overlapping frequency bands, wireless communication techniques may implement a local oscillator frequency for processing signals of a respective communication session that are harmonics of and may interfere with signals of another communication session processed by the respective wireless communication Tx/Rx chain. The intra-device interference experienced by one or more components of a wireless communication device caused by a simultaneous communication session is referred to herein as a coexistence situation. Co-existence interference typically degrades the radio performance of one or more of the multiple radio Tx/Rx chains. For example, wi-Fi WLAN communications may experience message failures, such as may result in an increased number of message retries. Such interference of coexistence situations is inconsistent with the goal of improving reliability in the explicit goal of the next generation Wi-Fi (also known as Ultra High Reliability (UHR), wi-Fi 8, or IEEE 802.11 bn).

The coexistence condition may be associated with interference at the apparatus experienced due to the first communication session and the one or more second communication sessions. According to some aspects, the processing system is further configured to cause the apparatus to obtain a first message from the wireless communication device. According to some aspects, the processing system is further configured to cause the apparatus to output a second message responsive to the first message for transmission. The second message may carry information about the coexistence situation.
