Abstract:
1. A method for wireless communication, comprising: transmitting, by an apparatus, to a second apparatus, a power decision pilot trigger; determining a set of time-frequency resources to use for transmitting a power decision pilot, the set of time-frequency resources including a fraction of time-frequency resources available for transmission; transmitting, by the apparatus, to the second apparatus, the power decision pilot on the set of time-frequency resources in a first time period to indicate a transmit power level to be used by the apparatus for data transmission in a second time period after the first time period, wherein transmitting the power decision pilot comprises transmitting a sequence of modulation symbols generated based on a pseudo-random sequence; receiving, by the apparatus, from the second apparatus, channel quality information (CQI), wherein the CQI is based on the power decision pilot and further based on a second power decision pilot from an interfering third apparatus, and wherein the CQI is received in response to the power decision pilot trigger; and transmitting, by the apparatus, to the second apparatus, data in accordance with the CQI.
