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 Bluetooth receiver. Bluetooth frequency channels are marked suitable or unsuitable for transmission based on the performance impact estimation and the state of the wireless cellular and Bluetooth connections. The estimation accounts for properties of the wireless cellular transmitter and Bluetooth receiver as well as operational characteristics of the wireless cellular and Bluetooth connections.
Claims24
A method of mitigating interference in a mobile wireless communication device, the method comprising:
- estimating a performance impact to signals received by a first transceiver of the mobile wireless communication device through a first wireless connection that uses a first frequency band from signals transmitted by a second transceiver of the mobile wireless communication device through a second wireless connection;
- changing the first wireless connection to exclude a portion of the first frequency band used by the first transceiver based on the performance impact estimation;
- and
- repeating periodically the estimating and changing while the first and second wireless connections are active.
A mobile wireless communication device, comprising:
- a first transceiver that receives signals through a first wireless connection;
- a second transceiver that transmits signals through a second wireless 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 in a first frequency band from signals transmitted by the second transceiver;
- changing the first wireless connection to exclude a portion of the first frequency band used by the first transceiver based on the performance impact estimation;
- and
- repeating periodically the estimating and changing while the first and second wireless connections are active.
Computer readable medium for tangibly storing computer program code executable by a processor for mitigating interference in a mobile wireless communication device comprising:
- computer program code for estimating a performance impact to signals received by a first transceiver of the mobile wireless communication device through a Bluetooth connection using a first frequency band from signals transmitted by a second transceiver of the mobile wireless communication device through a wireless cellular connection;
- computer program code for changing the Bluetooth connection to exclude a portion of the first frequency band used by the first transceiver based on the performance impact estimation;
- and
- computer program code for periodically repeating the estimating the performance impact and changing the Bluetooth connection while the Bluetooth and wireless cellular connections are active.
