    Abstract: Described herein are techniques for reducing interference to non-cellular communications on an unlicensed band by a network entity sending/receiving cellular communications on the unlicensed band. For example, the technique may involve operating in a first mode using a first radio access technology (RAT1), and collecting interference measurements for interference to or from at least one mobile device while in the first mode. The technique may also involve switching to a second mode and using a second radio access technology (RAT2), and using the interference measurements from the first mode to minimize interference caused or experienced by the network entity in the second mode.

    Abstract: Described features are directed to staggered frequency channel changing for cells of spectrum sharing networks. In some examples users communicating on one or more frequency channels of a spectrum sharing network may receive an indication that those channels are to be vacated, for example that the frequency channels are not to be transmitted on, or otherwise used for communications. Cells of the spectrum sharing network may receive the indication and perform staggered (e.g., sequential or randomly-timed) channel changes. The staggered channel changes may facilitate handover of user devices of the spectrum sharing network by, for example, reducing a number of cells that are simultaneously undergoing a channel change procedure. Thus, staggered frequency channel changing may reduce user service interruptions and radio link failures in a spectrum sharing network.

    Abstract: Described herein are techniques for reducing interference to non-cellular communications on an unlicensed band by a network entity sending/receiving cellular communications on the unlicensed band. For example, the technique may involve accessing a list of channels for cellular communication on the unlicensed band, the list having the channels in an order of priority for reducing interference to non-cellular communication on the unlicensed band. The technique may involve determining an interference criteria for a received signal, the interference criteria being based at in part on at least one of a received signal strength indicator (RSSI) or a duty cycle of the received signal. The technique may involve going through, in the order of priority, each channel in the list to identify a first channel that satisfies the interference criteria.

    Abstract: Disclosed are systems and methods for regulating frequent handovers by mobile devices between adjacent femtocells. In one aspect, the method includes determining if a mobile device is experiencing frequent handovers between femtocells, classifying frequent handovers based on cause (e.g., ping-pong between the two femtocells or high speed mobile device crossing a number of femtocells, etc.), and determining one or more remedial actions for regulation of frequent handovers based on the number of frequent handovers and their classification.
