TECHNIQUES FOR WIRELESS LOCAL AREA NETWORK (WLAN) SCANNING IN COEXISTENCE SCENARIOS

摘要

The present disclosure describes a method and an apparatus for techniques used for wireless local area network (WLAN) scanning in coexistence scenarios. For example, a method for is provided for WLAN scanning in which a scan of a WLAN is initiated at a wireless device configured to share an antenna for WLAN operations and Bluetooth (BT) operations while a voice call is in progress over the WLAN and packets from the voice call are routed between the wireless device and a BT device. A clear-to-send-to-self (CTS2Self) packet may be broadcast to reserve a communication channel for the wireless device after the scan is initiated. Moreover, a probe request may be broadcast after the broadcast of the CTS2Self packet, where the CTS2Self packet and the probe request are broadcast during a same WLAN interval of the WLAN operations and while the voice call is in progress over the WLAN.
