Power decision pilot for wireless communication

An apparatus for wireless communications, comprising:

• means for receiving, from a first base station, a request to transmit a first power decision pilot;
• means for determining a first set of time-frequency resources to use for transmitting the first power decision pilot, the set of time-frequency resources including a fraction of time-frequency resources available for transmission;
• means for transmitting based on receiving the request, the first power decision pilot on the first set of time-frequency resources in a first time period to indicate a first transmit power level to use for data transmission in a second time period after the first time period;
• means for receiving, from a second base station, an uplink grant based at least in part on the first power decision pilot and a second power decision pilot from another apparatus;
• and
• means for transmitting, to the second base station, data in accordance with the uplink grant.
