Abstract: A UE may use a same antenna for both Bluetooth communications and WWAN cell search and measurement operations. In order to avoid interference, the UE may adjust the periodicity of the WWAN cell search and measurement operations. Adjustment of the WWAN cell search and measurement periodicity may be based on a link quality of the Bluetooth communications.

Abstract: Systems and methods are described herein for providing a virtual conference using a master device implemented with a personal communication device (PCD), including determining, by the master device, a latency for each of a plurality of satellite devices connected to the master device. The master device then determines an uplink buffer duration based on a difference between a highest latency and a lowest latency among the plurality of satellite devices. The master device determines a processing time for an uplink data packet, the processing time being determined based, at least in part, on the uplink buffer duration. The master device then performs signal processing at the processing time for the received uplink data packets.
