Automatic transmit power control disabling
View Patent ↗A communications system in which a plurality of transmitter and receiver stations, wherein the transmitter stations are co-located in the same geographic area and capable of communication with each other and an improved method of Automatic Transmitter Power Control (ATPC) operation, wherein the method allows only one transmitter to engage in ATPC at a time per channel set and another improved method of ATPC in which there exists at least two co-located transmitters capable of ATPC operation and wherein the transmitters share transmitter ATPC status.
1. A method of communicating between plural transmitter stations and plural receiver stations, the method comprising the steps of:
providing plural transmitter stations co-located in the same geographic area and capable of communication with one another;
providing plural receiver stations;
providing Automatic Transmitter Power Control for each of said plural transmitter stations; and
engaging in Automatic Transmitter Power Control with one of said plural receivers and preventing others of said plural receivers from making a Automatic Transmitter Power Control request for Automatic Transmitter Power Control correction while engaged in Automatic Transmitter Power Control with the one of said plural receivers.
2. The method of claim 1 , wherein the Automatic Transmitter Power Control request is based on Automatic Transmitter Power Control triggering criteria.
3. The method of claim 2 , wherein the triggering criteria includes received bit error rate and received signal level.
4. The method of claim 1 , wherein the plurality of receiver stations are on adjacent or semi-adjacent RF channels.
5. The method of claim 4 , including the steps of: a requesting receiver station associated with one of the transmitters prompting the other transmitter stations to freeze requests for Automatic Transmitter Power Control correction for all of the other receiving stations.
6. The method of claim 5 , including the step of releasing the freeze when the link of the receiver station requesting Automatic Transmitter Power Control correction has reached its link objective.
7. The method of claim 6 , wherein the link objectives include received bit error rate and received signal level.
8. The method of claim 6 , wherein the step of releasing the freezing is performed via network connections.
9. The method of claim 6 , wherein the step of releasing the freezing is performed via a RF channel.
10. The method of claim 5 , wherein prompting the other transmitter stations is performed via network connections.
11. The method of claim 5 , wherein prompting the other transmitter stations is performed via a RF channel.
12. The method of claim 1 , wherein the selection of the one receiver station allowed to request Automatic Transmitter Power Control correction is based on a set of criteria.
13. The method of claim 12 , wherein the criteria is first come, first served.
14. The method of claim 12 , wherein the criteria is based on link characteristics.
15. A method of transmitting from plural transmitter stations on one or more channel sets, the method comprising the steps of:
providing plural transmitter stations co-located in the same geographic area and capable of communication with one another;
providing Automatic Transmitter Power Control for each of said plural transmitter stations; and
engaging in Automatic Transmitter Power Control with one of said plural transmitter stations on a channel set and during the engagement preventing others of said plural transmitter stations from engaging in Automatic Transmitter Power Control on the same channel set.
16. The method of claim 15 , wherein the channel sets include adjacent and semi adjacent RF channels.
17. The method of claim 16 , wherein the co located transmitters communicate Automatic Transmitter Power Control information with one another.
18. The method of claim 17 , wherein while one of the co-located transmitters is engaged in Automatic Transmitter Power Control operation, the other transmitters disable their respective Automatic Transmitter Power Control.
