Abstract: Methods, systems, and devices for wireless communication are described including determining one or more unfiltered CFOs, filtering the one or more unfiltered CFOs to identify a refined CFO based at least in part on the one or more unfiltered CFOs and a predetermined number of packets, modifying a transmission parameter based at least in part on the refined CFO, and transmitting a signal in a MU-MIMO environment based at least in part on the modified transmission parameter.

Abstract: Systems and methods are provided to improve roaming performance and to minimize disruptions in connectivity. When roaming between a source AP and a target AP, the device determines whether the APs employ different gateways, such as through an ARP exchange. If the source and target APs have different gateways, a DHCP exchange is used to renew the IP address of the device to restore network connectivity.

Abstract: Systems, methods, and devices for communicating data in a wireless communications network are described herein. In some aspects, a relay may associate with an access point and then clone the access point by transmitting the service set identifier of the access point. An association between a wireless node and a relay may be formed such that the relay provides relay services for wireless network communication between the access point and the wireless node. In some aspects, the relay may generate messages which communicate its available capacity so that downstream nodes may determine from which relays service may be available. In addition, each node may generate messages for upstream relays which communicate the load an association with the node would cause. Through such communication between relays, admission control may be used to minimize associations being dropped because of insufficient available capacity.
