Abstract:
In an example, there is disclosed an apparatus, having: a first network interface, having a first clock and a local communication driver to communicatively couple the first network interface to a second network interface having a second clock; and one or more logic elements, including at least one hardware logic element, providing a synchronization engine to: send a first plurality of data words from the first wireless interface to the second wireless interface via the local communication driver; receive back from the second wireless interface a second plurality of data words; assign a plurality of error rates to the data words of the second plurality of data words, the plurality of error rates indicating match or mismatch; identify a range of least error values within the plurality of error rates; and select an agreed baud rate from within the range.
Abstract:
Methods, devices and systems for dynamic scheduling of Bluetooth signals based at least in part on LTE schedules are disclosed. In some examples, Bluetooth can deduce information on the LTE DL/UL activity based at least in part on the LTE frame structure, LTE decision point or the LTE subframe boundary time. In some examples, Bluetooth scheduler can dynamically change the timing of the scheduling algorithm such that it may utilize the knowledge of LTE traffic and may at least partially avoid interference or evaluate the interference level.
Abstract:
The disclosure relates to a method for mitigating interference of a first radio signal received by a first transceiver of a first radio access technology (RAT) due to transmission of a second radio signal by a second transceiver of a second RAT, wherein the first transceiver and the second transceiver are physically collocated on a same device. The method includes: pre-setting a power of the second radio signal based on a throughput performance requirement for the first radio signal before transmission of the second radio signal, and tuning the power of the second radio signal during transmission of the second radio signal based on estimating the interference of the first radio signal.
Abstract:
Methods, devices and systems for dynamic scheduling of Wi-Fi or Bluetooth signals based at least in part on LTE schedules are disclosed. In some examples, Wi-Fi or Bluetooth can perform coexistence decisions including Wi-Fi and Bluetooth channel or Adaptive Frequency Hopping (AFH) selection based on modem calculated Rx or Tx indications and device geo location, maximum allowed transmit power per channel for Wi-Fi, and the LTE modem connection state.
Abstract:
An interfering signal from a co-running modem is filtered using a notch filter to cancel high frequency harmonic interference to a received radio frequency (RF) signal. Thereafter, a metric scaling and tone nulling are performed in the received RF signal to further eliminate residual harmonic frequencies.
