Coexistence of Plural Wireless Communication Transceivers in Close Proximity
First Claim
1. A method of operating a communication device having a plurality of concurrently operating transceivers, each operating in a respectively different one of a plurality of communication systems, wherein the plurality of concurrently operating transceivers includes a first transceiver and a second transceiver, the method comprising:
- the first transceiver ascertaining whether transmissions by the second transceiver are causing interference in a receiver of the first transceiver and if so, performing one or more interference response actions,wherein the one or more interference response actions include;
ascertaining whether the interference is at an acceptable level and if so then taking no further interference response actions; and
if the interference is ascertained to be at an unacceptable level, then communicating an interference mitigation request to the second transceiver,wherein;
the second transceiver is operating on a first frequency in a first frequency band; and
the first frequency band at least partially overlaps with at least one of a passband and a transition band of a band select filter of the first transceiver'"'"'s receiver.

Abstract
A communication device has a plurality of concurrently operating transceivers, each operating in a respectively different one of a plurality of communication systems, wherein the plurality of concurrently operating transceivers includes a first transceiver and a second transceiver. Operation of the communication device includes the first transceiver ascertaining whether transmissions by the second transceiver are causing interference in a receiver of the first transceiver and if so, performing one or more interference response actions. The one or more interference response actions include ascertaining whether the interference is at an acceptable level and if so then taking no further interference response actions. If the interference is ascertained to be at an unacceptable level, an interference mitigation request is communicated to the second transceiver. The second transceiver can, for example, shift its use of frequencies to a region whereby the first transceiver'"'"'s band select filter can sufficiently attenuate the second transceiver'"'"'s signal.

8. An apparatus for operating a communication device having a plurality of concurrently operating transceivers, each operating in a respectively different one of a plurality of communication systems, wherein the plurality of concurrently operating transceivers includes a first transceiver and a second transceiver, the apparatus comprising:
-
circuitry associated with the first transceiver and configured to ascertain whether transmissions by the second transceiver are causing interference in a receiver of the first transceiver and if so, to perform one or more interference response actions, wherein the one or more interference response actions include; ascertaining whether the interference is at an acceptable level and if so then taking no further interference response actions; and if the interference is ascertained to be at an unacceptable level, then communicating an interference mitigation request to the second transceiver, wherein; the second transceiver is configured to operate on any of a plurality of frequencies including a first frequency in a first frequency band; and the first frequency band at least partially overlaps with at least one of a passband and a transition band of a band select filter of the first transceiver'"'"'s receiver. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
