    Abstract: Disclosed are techniques for accessing a shared communication medium. An aspect includes communicating over the shared communication medium in accordance with a Time Division Duplexing (TDD) frame structure defining a set of downlink subframes and a set of uplink subframes, each uplink subframe being divided into a transmission gap period, a contention-exempt period, and a contention-compliant period, performing a contention procedure for contending for access to the shared communication medium during the transmission gap period, selectively transmitting contention-compliant uplink control signals during the contention-compliant period, and transmitting one or more contention-exempt uplink control signals during the contention-exempt period. An aspect includes receiving a downlink subframe of the shared communication medium and transmitting an acknowledgment of the downlink subframe during an uplink subframe of the shared communication medium, the uplink subframe occurring at least a predetermined number of subframes and/or at least a predetermined amount of time after the downlink subframe.

    Abstract: The disclosure is related to selecting an operating channel for a cellular network to reduce interference to a wireless local area network (WLAN) operated by a small cell comprising a WLAN access point and a cellular network modem. The small cell performs a channel scan of available channels, determines whether or not there is a clean channel to be the operating channel for the cellular network based on the channel scan, wherein a clean channel comprises a channel that interferes with the WLAN less than a WLAN interference threshold, and selects the clean channel as the operating channel for the cellular network based on the clean channel being available or turns off the cellular network based on no clean channel being available.

    Abstract: Techniques for access terminal radio link monitoring on a shared communication medium are disclosed. In an aspect, an access terminal detects a missed reference signal event associated with a radio link established on the shared communication medium, wherein detecting the missed reference signal event comprises determining that the access terminal did not detect a reference signal for measuring a quality of the radio link transmitted during a reference signal configuration window, assigns an error metric to the missed reference signal event based on reference signal monitoring capabilities of the access terminal, and triggers a radio link failure based on the assigned error metric. In an aspect, the missed reference signal event may be a missed Discovery Reference Signaling (DRS) event, the error metric may be a Block Error Rate (BLER) weight, and the reference signal for measuring the quality of the radio link comprises a Cell-specific Reference Signal (CRS).
