A communication device includes a first network interface configured to communicate in a first network according to a first communication protocol, and a second network interface configured to communicate in a second network according to a second communication protocol. The first communication protocol defines a periodically repeating frame. The communication device predicts one or more subframes in the frame in which a serving base station in the first network will not transmit to the communication device because of poor channel conditions using at least one of i) measured channel quality in the one or more subframes, and ii) instructions sent to the communication device regarding channel quality measurements that are to be reported. In response to predicting the one or more subframes, operation of the first network interface is suspended during those subframes, and operation of the second network interface is enabled during at least one of those subframes.
