Apparatus for placing power control data in a transmission signal
View Patent ↗A device for placing power control data in a transmission signal has: a generating device for generating power control data as a function of a received signal, a buffer for buffering a formatted transmission data word that contains a power control data field for recording power control data, an inserting device for inserting the generated power control data into the power control data field of the buffered transmission data word, and a modulation device for modulating the transmission data word to form a transmission signal with a transmission power corresponding to the power control data.
1. An apparatus for placing power control data in a transmission signal, comprising:
a formatting device for formatting coded transmission data into a formatted transmission data word having a power control data field for recording power control data, said formatting device filling the power control data field of the formatted transmission data word with predetermined filler data causing no change in a transmission power;
a generating device for generating power control data as a function of a received signal;
a buffer for buffering the formatted transmission data word;
an inserting device for overwriting the filler data in the power control data field of the formatted transmission data word in said buffer by inserting the power control data from said generating device into the power control data field of the formatted transmission data word in said buffer; and
a modulation device for modulating the formatted transmission data word to form a transmission signal with a transmission power corresponding to the power control data.
2. The apparatus according to claim 1 , wherein the transmission signal is a CDMA transmission signal.
3. The apparatus according to claim 2 , wherein said generating device generates the power control data from the received signal using a signal-to-interference plus noise ratio estimate SINR.
4. The apparatus according to claim 1 , wherein said generating device generates the power control data from the received signal using a signal-to-interference plus noise ratio estimate SINR.
5. The apparatus according to claim 1 , wherein the formatted transmission data word includes a plurality of data fields.
6. The apparatus according to claim 1 , wherein the formatted transmission data word h as a length of a CDMA time slot.
7. The apparatus according to claim 1 , comprising: a signal bus connecting said formatting device to said buffer.
8. The apparatus according to claim 1 , wherein said modulation device is a digital modulator.
9. The apparatus according to claim 1 , comprising: a digital-to-analog converter connected downstream from said modulation device.
