Abstract: A front-end module and antenna can be shared between two radio transceivers operating in coexistent radio frequency (RF) communication bands. For example, a first of the two radio transceivers may operate in one of a Long Term Evolution (LTE) band or an Industrial Scientific Medical (ISM) band, while a second of the two radio transceivers may operate in an alternative one of the LTE band and the ISM band. Use of a diplexer in the shared front-end module to pass RF signals between the two radio transceivers and the shared antenna can allow for sufficient isolation to avoid interference between transmit and receive operations in the coexistent RF communication bands.

Abstract: A coexistence signaling scheme for radio communications is described. In one embodiment, a method for coexistence signaling includes establishing first communications and second communications with separate access points or base stations. The method further includes determining protocol timings of the first and second communications. Based on various communications parameters, protocol timings, and identified interference conditions, the method includes generating one or more priority signals to manage the first and second communications. According to certain aspects, overlapping channel conditions can be avoided while maintaining acceptable communications data throughput.

Abstract: In collocated radios, interference is mitigated to permit concurrent radio operation. In response to detection of imminent transmission of interfering wireless (i.e., RF jammer) signals, gain settings of one or more stages of front-end receiver amplifiers may be quickly configured to permit concurrent frequency division operation instead of consecutive time-division operation. This expansion of concurrent operation may improve communication bandwidth and/or may produce reliable, consistent results. Gain control responsive to detection of imminent RF jamming may maintain amplification in a linear range where interference can be filtered out. Receiver gain may be shifted from a default high gain or high sensitivity setting to lower gain to maintain integrity of a signal of interest (SoI), which avoids clipping, distortion and unwanted products caused by a high power jamming signal that could otherwise make it impossible to recover the SoI. This mitigation technique supplements and/or replaces other interference mitigation techniques.
