Abstract
Mitigating interference in a mobile wireless communication device by using an estimation of the performance impact of interfering signals generated by a wireless cellular transmitter and received by a co-located wireless local area network receiver. Wireless local area network frequency band usage is modified based on the performance impact estimation and the state of the wireless cellular and wireless local area network connections. The estimation accounts for properties of the wireless cellular transmitter and wireless local area network receiver as well as operational characteristics of the wireless cellular and wireless local area network connections.
Claims24
A method of mitigating interference in a mobile wireless communication device, the method comprising:
- estimating a performance impact to signals received in a first frequency band by a first transceiver of the mobile wireless communication device through a wireless local area network connection with a first wireless local area network partner device from signals transmitted by a second transceiver of the mobile wireless communication device through a wireless cellular connection;
- changing the wireless local area network connection to use a second frequency band based on the performance impact estimation;
- and
- repeating periodically the estimating and changing while the wireless local area network and wireless cellular connections are active.
A mobile wireless communication device, comprising:
- a first transceiver that receives signals through a wireless local area network connection;
- a second transceiver that transmits signals through a wireless cellular connection;
- and
- a control processor coupled to the first and second transceivers, wherein the control processor mitigates interference in the mobile wireless communication device by:
- estimating a performance impact to signals received by the first transceiver from signals transmitted by the second transceiver;
- changing the wireless local area network connection to use a second frequency band based on the performance impact estimation;
- and
- repeating periodically the estimating and changing while the first and second wireless connections are active.
