TV MANAGING TRANSMIT POWER AND MODULATION AND CODING SCHEME SELECTION DURING RANDOM ACCESS IN TV WHITE SPACE

摘要

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, media reuse in such networks can be improved and unfair use problems can be mitigated. One exemplary method includes receiving a request message including an indication of a modulation and coding scheme (MCS) for transmitting data frames to be received, determining a link margin based on the MCS, and displaying a link margin And sending a response message with the response message. Another exemplary method generally comprises determining an MCS for transmitting data frames and sending a request message comprising an indication of the MCS.
