Abstract: The present disclosure presents a method and apparatus for identifying an access point (AP) for selection by an access terminal (AT). For example, the method may include receiving a probe request by one or more APs from an AT, wherein the probe request is broadcasted by the AT to the one or more APs, generating load information and Received Signal Strength Indicator (RSSI) values of the probe request at the one or more APs, identifying an AP of the one or more APs for selection by the AT, wherein the AP for selection by the AT is identified by the one or more APs based at least on the load information and RSSI values generated at the one or more APs, and transmitting information of an AP identified by the one or more APs to the AT. As such, an improved mechanism for selecting an access point may be achieved.

Abstract: Techniques for managing re-contention on a shared communication medium are disclosed. In order to facilitate re-contending for access to the communication medium, an access point may adjust one or more uplink transmission parameters associated with a triggering condition for invoking a contention timer. In addition or as an alternative, the access point may mute transmission on the communication medium during one or more symbol periods designated for transmission. In addition or as an alternative, the access point may configure a timing advance to create a re-contention gap.

Abstract: Techniques for co-existence between wireless Radio Access Technologies (RATs) and related operations in shared spectrum are disclosed. Operation on a communication medium shared between RATs may be managed by a transceiver configured to operate in accordance with a first RAT and to monitor the medium for signaling associated with a second RAT. A medium analyzer may be configured to determine one or more Time Division Multiplexing (TDM) parameters of a TDM communication pattern associated with the second RAT based on the monitored signaling. A transmission controller may be configured to set one or more transmission parameters for the first RAT based on the determined one or more TDM parameters. The transceiver may be further configured to transmit on the medium in accordance with the one or more transmission parameters.

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.
