Abstract: Techniques for managing operation over a communication medium shared between Radio Access Technologies (RATs) are disclosed. In one example, one or more parameters of a Time Division Multiplexing (TDM) communication pattern may be set to define activated periods and deactivated periods for communication over the medium. A first interlace may be selected among a plurality of interlaces for communication over the medium, the first interlace being reserved for a first operator. During the first interlace, transmission over the medium may be cycled in accordance with the TDM communication pattern, and deactivated during a second interlace among the plurality of interlaces that is reserved for a second operator.

Abstract: Techniques for channel selection and related operations in a shared spectrum environment are disclosed. In one example, a channel selector or the like may be used to select one of a number of available channels as an operating channel based on a comparison of cost functions for each of the available channels, with the cost functions being based on separate utility and penalty metrics. In another example, a channel scanner or the like may be used to trigger a channel scan in response to a channel quality metric indicating poor service for a threshold number or proportion of access terminals. In another example, an operating mode controller may be used to trigger a Time Division Multiplexing (TDM) mode on an operating channel in response to a utilization metric being above a threshold. The TDM mode may cycle operation between activated and deactivated periods in accordance with a TDM communication pattern.

Abstract: The various embodiments include methods for managing how a DSDS mobile communication device that is accessing an arbitrary combination of any two mobile telephony networks processes paging collisions. The embodiment methods promote the control of the paging block rates for two distinct subscriptions, in which a subscription's paging block rate is the long-term percentage of its blocked paging messages over its total number of received paging messages. In the various embodiments, a mobile communication device may use a paging blocking bias to achieve a particular paging blocking rate. The paging blocking bias may be set or adjusted through various means to cause a first subscription to have a paging blocking rate that is less than, equal to, or greater than a paging blocking rate for a second subscription.

Abstract: A system for self-configuration of power control parameters based on path-loss is operable by a network entity that determines a default power parameter for an access terminal. The network entity determines a path-loss difference between a first path-loss for the access terminal to a serving cell and a second path-loss for the access terminal to a neighboring cell. A power control parameter is determined based on the default power parameter and the pass-loss difference. A system for self-configuration of power control parameters based on downlink power is operable by a network entity that determines a default power parameter for an access terminal. The network entity determines a downlink power difference between a downlink power of a serving cell and a downlink power of a neighboring cell. A power control parameter is determined based on the default power parameter, the downlink power difference.
