Abstract
A telecommunication system has a wireless transmitter that transmits data stream signals via multiple channels over a plurality of antennas, the transmitter having a power controller that selects transmission power loading per channel. The telecommunication system further has a wireless receiver that receives data stream signals from the transmitter, and the receiver has a detector that estimates power loading selections of the transmitter. The controller further quantizes the power loading values, and the detector uses the quantized power loading values to automatically estimate power loading selection by the transmitter.
Claims23
A telecommunication system, comprising:
- a wireless transmitter that transmits data stream signals via multiple channels over a plurality of antennas, the transmitter including a power controller that selects transmission power loading per channel;
- and
- a wireless receiver that receives data stream signals from the transmitter, wherein the receiver comprises a detector that automatically estimates power loading selections of the transmitter.
A closed-loop signaling method over multiple channels in a telecommunication system, comprising the steps of:
- obtaining an information bit stream;
- determining transmission power loading per channel according to channel condition;
- transmitting the information bit stream via said multiple channels over a plurality of antennas of a transmitter according to the power loading per channel;
- receiving the transmitted bits streams in a receiver;
- and
- estimating that transmit power loading of the transmitter at the receiver.
