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: An apparatus configured to establish a first radio link for short range communications using a first protocol and a second radio link for short range communications using a second protocol, wherein the first and second radio links share an antenna, process traffic load information for the first radio link, the information being dependent on configuration parameters for the first radio link, determine, based on the information, time domain resources available for second data traffic on the second radio link, based on the time domain resources available for the second data traffic on the second radio link, determine a fragmentation size for packets sent on the second radio link and generate transmissions to exchange the second data traffic in the time domain resources available for the second data traffic on the second radio link in fragmented packets according to the determined fragmentation size.

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.
