    Abstract: An access point (AP) transmits Wi-Fi transmit frames according to a Wi-Fi protocol and Long-Term Evolution-Unlicensed (LTE-U) transmit frames according to an LTE-U protocol in a shared channel bandwidth that encompasses unlicensed channel bandwidth associated with the LTE-U protocol. The AP assigns a Wi-Fi access category to each Wi-Fi transmit frame and assigns to each LTE-U transmit frame an LTE-U access category. The AP schedules Wi-Fi and LTE-U transmit opportunities for the Wi-Fi transmit frames and the LTE-U transmit frames, respectively, in the shared channel bandwidth based on the Wi-Fi and LTE-U access categories. The scheduling includes, for each scheduled LTE-U transmit opportunity: constructing a Wi-Fi quiet message commanding Wi-Fi clients of the AP not to transmit in the shared channel bandwidth during the LTE-U transmit opportunity; and scheduling the Wi-Fi quiet message for transmission to the Wi-Fi clients.

    Abstract: A wireless access point that serves one or more wireless client devices in a wireless network determines that at least one particular client device that is associated to the wireless access point should not be associated to the wireless access point. The wireless access point transmits frames so that they are received at the particular client device with reduced strength so as to provoke the particular client device to transition from the wireless access point.

    Abstract: Presented herein are techniques for using uplink transmissions from devices (e.g., wireless tags, clients, etc.) to determine a path loss between neighboring access points. In one example, a wireless controller obtains receive signal strength information of uplink transmissions received at neighboring access points in a wireless network. The wireless controller determines an effective path loss between the neighboring access points based on the receive signal strength information for the uplink transmissions received at the neighboring access points. The wireless controller also performs radio resource management operations in the wireless network using the effective path loss determined based on the uplink transmissions received at the neighboring access points.

    Abstract: Dynamic bandwidth selection techniques are provided for a plurality of wireless access point devices that operate in a wireless local area network. Each access point device is capable of serving wireless client devices with a bandwidth from a set of possible bandwidths associated with one or multiple contiguous or non-contiguous radio frequency channels. A bias is generated based on determined type of traffic or client composition for each access point device, the bias favoring a channel assignment that results in a particular bandwidth in the set of bandwidths. The bias is applied to metrics representing severity and degree of interference for each channel to generate adjusted metrics. A bandwidth from the set of possible bandwidths is selected for each access point device based on the adjusted metrics.

    Abstract: Techniques are presented herein for providing hybrid contention mechanisms for a wireless medium. A first wireless device (e.g., a wireless access point) that serves a plurality of second wireless devices (e.g., client devices) in a wireless network, groups the plurality of second wireless devices into sets based on commonality of the second wireless devices in terms of one or more of: power requirements and throughput requirements. A time interval on a wireless channel during which the second wireless devices may contend for usage of the wireless medium is partitioned into a plurality of disjoint or overlapping contention periods. Each set of second wireless devices is assigned to a corresponding one of the plurality of contention periods such that only second wireless devices in each set contend for access to the wireless channel during the corresponding contention period assigned to that set.

    Abstract: A Long-Term Evolution-Unlicensed (LTE-U) access point (AP) is configured to operate wirelessly on any of multiple RF channels in an unlicensed frequency band. The AP detects other LTE-U APs and Wi-Fi APs operating on active ones of the multiple channels. The AP determines AP channel statistics for each detected AP. The AP determines, for each active channel, a per-channel metric based on the AP channel statistics. The AP ranks the active channels according to the corresponding per-channel metrics, and selects a best channel on which to transmit in the unlicensed frequency band from among the ranked active channels based on the rankings.
