Abstract: Techniques for co-existence on a shared communication medium are disclosed. To foster co-existence, operation of a first Radio Access Technology (RAT) may be cycled between active periods and inactive periods of transmission, on a communication medium shared with a second RAT, in accordance with a Discontinuous Transmission (DTX) communication pattern. An identifier may be selected for association with the first RAT. A channel reservation message associated with the second RAT may then be transmitted, over the communication medium, to reserve the communication medium for one of the active periods, the channel reservation message including the identifier.

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: Apparatus and methods of wireless communications are described for determining one or more bands (e.g., guard bands in wireless local area networks (WLANs)) in unused portions of an unlicensed spectrum, positioning one or more carriers for cellular communication (e.g., long term evolution (LTE) or LTE advanced communication) in the one or more bands, and performing the cellular communication over the unlicensed spectrum using the one or more carriers. In some non-limiting example aspects, the cellular communication may be in a standalone mode and the one or more carriers may include a primary component carrier (PCC) that is positioned in a Wi-Fi guard band. In these non-limiting example aspects, the apparatus and methods may further include allocating one or more secondary component carriers (SCCs) in Wi-Fi guard bands or in Wi-Fi channels, where the one or more SCCs are opportunistically tuned or turned ON/OFF based on cell loading or backhaul constraints.

Abstract: Systems and methods for Carrier Sense Adaptive Transmission (CSAT) and related operations in unlicensed spectrum are disclosed to reduce interference between co-existing Radio Access Technologies (RATs). The parameters for a given CSAT communication scheme may be adapted dynamically based on received signals from a transceiver for a native RAT to be protected and an identification of how that RAT is utilizing a shared resource such as an unlicensed band. Other operations such as Discontinuous Reception (DRX) may be aligned with a CSAT Time Division Multiplexed (TDM) communication pattern by way of a DRX broadcast/multicast message. Different TDM communication patterns may be staggered in time across different frequencies. Channel selection for a co-existing RAT may also be configured to afford further protection to native RATs by preferring operation on secondary channels as opposed to primary channels.
