Abstract
A method and device for power indication information transmission are provided. The method includes receiving data subjected to inverse fast fourier transform (IFFT); buffering the received data within the time slot; determining power of the received data within the time slot; sending power indication information and the received data respectively, wherein the power indication information includes information of the power of the received data within the time slot. Therefore, power saving is improved significantly, and DPD also can get benefit from power indication information for pre-distortion processing.
Claims8
A method for power indication information transmission, comprising:
- receiving data subjected to inverse fast fourier transform (IFFT);
- buffering the received data within a time slot;
- determining a power level of the received data for each orthogonal frequency division multiplexing (OFDM) symbol within the time slot;
- sending separately, power indication information and the received data, wherein the power indication information comprises a respective power indication field for each OFDM symbol within the time slot, wherein each respective power indication field indicates the determined power level of the received data for the corresponding OFDM symbol.
A device for power indication information sending, comprising a processor and a memory wherein the memory containing instructions executable by the processor whereby the device is operative to:
- receive data subjected inverse fast fourier transform (IFFT);
- buffer the received data within a time slot;
- determine a power level of the received data for each orthogonal frequency division multiplexing (OFDM) symbol within the time slot;
- send separately, power indication information and the received data, wherein the power indication information comprises a respective power indication field for each OFDM symbol within the time slot, wherein each respective power indication field indicates the determined power level of the received data for the corresponding OFDM symbol.
