Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for load balancing network traffic in a wireless network. In one aspect, an access point may determine a plurality of client devices that are associated with an overloaded channel of the wireless network. The access point may identify a first client device of the plurality of client devices based, at least in part, on an airtime consumed on the overloaded channel. The access point may determine one or more alternate paths between the access point and the first client device. The access point may forecast airtime to be used by the first client device on channels of the one or more alternate paths, and steer wireless network traffic of the first client device to a first alternate path of the one or more alternate paths based, at least in part, on the forecasted airtime.

Abstract: Certain aspects of the present disclosure provide techniques and apparatus for managing transmit power in a television white space (TVWS) network. One example method generally includes transmitting a sequence of request-to-send (RTS) messages at different transmit power levels to an apparatus and determining if a clear-to-send (CTS) message was received in response to at least one of the RTS messages corresponding to a particular one of the transmit power levels. Another example method generally includes receiving, at a first apparatus from a second apparatus, a packet that cannot be decoded by the first apparatus; determining at least one of a time or a duration corresponding to the packet; transmitting a query with an indication of the at least one of the time or the duration; and receiving a message from the second apparatus in response to the query, the message identifying the second apparatus as a source of the packet.

Abstract: Systems, methods, and devices to communicate in a white space are described herein. In some aspects, wireless communication transmitted in the white space authorizes an initial transmission by a device. The wireless communication may include power information for determining a power at which to transmit the initial transmission. The initial transmission may be used to request information identifying one or more channels in the white space available for transmitting data. In some aspects, a device for wireless communication is disclosed. The device may include a data interleaver with at least a first mode and a second mode. The modes may correspond to transmitting using either two or four channels of the white space.

Abstract: A method includes determining, at a first transmitter, a clear channel access (CCA) threshold associated with reuse of a first transmit opportunity (TXOP) of a message. The method further includes sending, from the first transmitter to a first receiver, at least a portion of the message, wherein the portion of the message indicates the CCA threshold.
