  • Patent number: 10448292
    Abstract: A parameter for transmission by an access point is determined in a manner that facilitates access terminal mobility. For example, a cell reselection parameter and/or a handover parameter may be determined based on the quality of a signal from one access point (e.g., a macro cell) at another access point (e.g., a femto cell). In addition, a cell reselection parameter and/or a handover parameter may be determined based on the proximity of one access point (e.g., a femto cell) to another access point (e.g., a macro cell). Through the use of these techniques, a parameter may be determined in a manner that mitigates access terminal ping-ponging between access points and that mitigates outages that may otherwise occur as a result of an access terminal remaining on an access point too long.

  • Publication number: 20180376341
    Abstract: Techniques and apparatus for channel mapping in shared spectrum in the presence of higher tier users are provided. One technique includes evaluating, for different channel locations of orthogonal channel(s) within available spectrum, an amount of transmission limitation imposed to a group of devices due to incumbent protection, an amount of available bandwidth, and/or a maximum contiguous channel size. A channel location is assigned to each orthogonal channel, based on the evaluation. Another technique includes determining first channel location(s) in order to assign at least a first orthogonal channel within available spectrum. Each first orthogonal channel is associated with a group of devices sharing bandwidth within one or more networks. An exchange is participated in with a network entity to share a first set of information associated with the first channel locations. A determination is made whether to modify portion(s) of the first set of information, based on the exchange.

  • Patent number: 10136340
    Abstract: Systems and methods are provided for a femto node to configure one or more of its RF parameters. This may be achieved, for example, by determining capabilities of one or more neighboring femto or pico nodes based in part on signals received from the one or more neighboring femto or pico nodes, comparing the determined capabilities of the one or more neighboring femto or pico nodes to one or more capabilities of the femto node, and adjusting one or more RF parameters of the femto node based on the comparison.

  • Patent number: 10136330
    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.

  • Publication number: 20180227954
    Abstract: Techniques for mobility-aware contention procedures on a shared communication medium are disclosed. A connection failure associated with mobility between a source access point and a target access point sharing a communication medium may be detected. Based on the detected connection failure, a backoff threshold associated with contention-based access to the communication medium may be adapted. Contention for access to the communication medium may then proceed in accordance with the adapted backoff threshold.
