Abstract: Wireless communications systems may detect network attacks based on analysis of medium access control (MAC) addresses and origination locations associated with incoming authentication requests. For example, a DoS attack may be detected by determining (e.g., via a database) whether a particular MAC address is associated with multiple authentication request messages without proceeding to an authentication step. According to the described techniques, a system (e.g., an AP, controller/cloud, etc.) may maintain a database of authentication requests and associated MAC addresses, timestamps, and location information. As such, upon reception of an authentication request corresponding to a MAC address, the MAC address may be compared to the database. If the delta (e.g., timestamp difference) between authentication requests from a same MAC address is less than a threshold, the system may detect a potential DoS attack by a client associated with the MAC address and the MAC address may be removed from the AP.

Abstract: Techniques for wireless communication are described. One method includes receiving, at a first protocol layer of a wireless communications device, data flows from a second protocol layer for transmission on a first sub-band of a shared radio frequency spectrum band or a second sub-band of the shared radio frequency spectrum band, the second protocol layer being a higher protocol layer than the first protocol layer; scheduling the data flows from the first protocol layer or the second protocol layer to the first sub-band of the shared radio frequency spectrum band or the second sub-band of the shared radio frequency spectrum band based on a parameter associated with the data flows and at least one metric associated with at least one of the first sub-band or the second sub-band; and aggregating the data flows for transmission over the first sub-band and the second sub-band based on the scheduling.

Abstract: Aspects relate to a priority mechanism for prioritizing network identifiers, for example SSIDs. As described herein, a UE may obtain one or more network identifier sets, each of the one or more network identifier sets having one or more network identifiers for a first RAT and a priority level, determine one or more of the network identifier sets that are under control of a second RAT, and after the determining, manage connections to the first RAT based, at least in part, on the priority level of the network identifier sets.
