Abstract
Certain aspects of the present disclosure provide techniques and apparatus for managing transmit power in a television white space (TVWS) network. By managing transmit power as described herein, medium re-use may be improved in such a network, and unfair usage problems may be alleviated. One example method generally includes receiving, from an apparatus, a message with an indication of a highest transmit power used by the apparatus for transmitting data frames; and determining that the apparatus is a dominant interferer based, at least in part, on the highest transmit power. Another example method generally includes receiving, from an apparatus, a control or management message with a first indication of a first transmit power used by the apparatus for transmitting data frames; and determining that the apparatus is a dominant interferer based, at least in part, on the first transmit power.
