Apparatus and method 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 first device that inserts coded transmission data into a formatted transmission data word having a power control data field for recording power control data, and that fills the power control data field with predetermined filler data;
a second device that generates power control data as a function of a received signal;
a third device that changes the filler data word by inserting the power control data from said generating device into the power control data field of the formatted transmission data word.
2. The apparatus according to claim 1 , further comprising a fourth device that buffers the formatted transmission data word.
3. The apparatus according to claim 1 , further comprising a fifth device that modulates the formatted transmission data word to form a transmission signal with a transmission power corresponding to the power control data.
4. The apparatus according to claim 1 , wherein the transmission signal is a CDMA transmission signal.
5. The apparatus according to claim 1 , wherein said second device generates the power control data from the received signal using a signal-to-interference plus noise ratio estimate SINR.
6. The apparatus according to claim 1 , wherein the formatted transmission data word includes a plurality of data fields.
7. The apparatus according to claim 1 , wherein the formatted transmission data word has a length of a CDMA time slot.
8. The apparatus according to claim 2 , further comprising a signal bus connecting said first device to said fourth device.
9. The apparatus according to claim 3 , wherein said fifth device is a digital modulator.
10. The apparatus according to claim 3 , further comprising a digital-to-analog converter connected downstream from said fifth device.
11. A method for placing power control data in a transmission signal, comprising:
inserting coded transmission data into a formatted transmission data word having a power control data field for recording power control data;
filling the power control data field with predetermined filler data;
generating power control data as a function of a received signal;
changing the filler data word by inserting the power control data from said generating device into the power control data field of the formatted transmission data word.
12. The method according to claim 11 , wherein no change in a transmission power is caused when filling the power control data field with predetermined filler data.
13. The method according to claim 11 , further comprising buffering the formatted transmission data word.
14. The method according to claim 11 , further comprising modulating the formatted transmission data word to form a transmission signal with a transmission power corresponding to the power control data.
15. The method according to claim 11 , wherein the transmission signal is a CDMA transmission signal.
16. The method according to claim 11 , wherein the power control data is generated as a function of a received signal by using a signal-to-interference plus noise ratio estimate SINR.
17. The method according to claim 11 , wherein the formatted transmission data word includes a plurality of data fields.
18. The method according to claim 11 , wherein the formatted transmission data word has a length of a CDMA time slot.
