Abstract: Methods and apparatuses for mitigating coexistence interference in a wireless device between a WLAN interface and a WPAN interface during a WLAN authentication process. The wireless device associates with a WLAN access point (AP), and after receiving a WLAN association response from the WLAN AP, the wireless device alternates between WLAN time periods, during which WLAN transmission is enabled and WPAN transmission is disabled, and WPAN time periods, during which WPAN transmission is enabled and WLAN transmission is disabled, during the WLAN authentication process. Durations of the WPAN time periods are based at least in part on a WPAN profile, e.g., a Bluetooth profile, in use by the wireless device. Durations of the WLAN time periods are based at least in part on receipt of WLAN authentication messages from the WLAN AP during the authentication process or expiration of WLAN authentication process timers.

Abstract: Methods and apparatuses for managing coexistence of multiple wireless devices that share a radio frequency band and communicate with a wireless network device. The wireless devices include both wireless personal area network (WPAN) and wireless local area network (WLAN) devices. The wireless network device monitors data activity for WPAN devices to determine whether the WPAN devices are active or inactive, and sets one or more polling intervals for the WPAN devices accordingly. The wireless network device consolidates polling for multiple WPAN devices into a common WPAN polling time period and sends a radio frequency (RF) reservation request to a WLAN access point (AP), the RF reservation request including an indication of a duration for the common WPAN polling time period, during which the multiple WPAN devices are polled. WLAN data packet transmission is delayed during the common WPAN polling time period to mitigate coexistence interference.

Abstract: A method for receiving feedback on a quality of multicast transmissions in a Wireless Local Access Network (WLAN) including a source electronic device (e.g., an access point) and a plurality of electronic devices is disclosed, according to some embodiments. The method can include (i) transmitting a plurality of multicast packets addressed to a subset of the plurality of electronic devices by the source electronic device; (ii) concurrently polling the subset of the plurality of electronic devices by the source electronic device; and (iii) receiving a plurality of block acknowledgements (BAs) from at least the subset of the plurality of electronic devices by the source electronic device. Each BA may include information on a quality of reception of two or more multicast packets received at an electronic device.
Abstract translation: 根据一些实施例，公开了一种用于在包括源电子设备（例如，接入点）和多个电子设备的无线本地接入网络（WLAN）中接收关于多播传输质量的反馈的方法。 该方法可以包括（i）由源电子设备发送寻址到多个电子设备的子集的多个多播分组; （ii）由所述源电子设备同时轮询所述多个电子设备的子集; 以及（iii）由所述源电子设备从所述多个电子设备的至少所述子集接收多个块确认（BAs）。 每个BA可以包括关于在电子设备处接收的两个或多个多播分组的接收质量的信息。
