Abstract

Claims (19)

1. A method for implementing transmission parameter control at a transmitting station, comprising:

executing instructions stored in memory, wherein execution of the instructions by a processor queries a transmission parameter control module for a corresponding transmission schedule of a plurality of transmission schedules, the corresponding transmission schedule comprising a plurality of schedule entries defining a set of transmission parameter controls associated with a destination address and one or more link quality metrics associated with the set of transmission parameter controls, the link quality metrics including data rate, success ratio, a received signal strength indicator (RSSI) and error vector magnitude (EVM), wherein each schedule entry is:

associated with a scheduled transmission attempt for the destination address,

associated with the destination address,

indicative of more than message packets in transit as belonging to a particular packet flow, and

at least two of the schedule entries include different transmission parameter control values;

and transmitting, based on the one or more link quality metrics, at least one packet of data to the destination address according to the transmission parameter controls of at least one schedule entry of the plurality of schedule entries from the corresponding transmission schedule.

2. The method of claim 1 , further comprising receiving at the transmitting station an acknowledgment of receipt of the transmitted at least one packet of data in accordance with the at least one schedule entry.

3. The method of claim 2 , further comprising providing feedback data related to the transmission of the at least one packet of data in accordance with the at least one schedule entry associated with the acknowledged transmission.

4. The method of claim 1 , further comprising execution of instructions by the processor to:

determine that an acknowledgment of receipt of the transmitted at least one packet of data has not been received by the transmitting station; and

search the corresponding transmission schedule for an unused schedule entry for re-transmission of the at least one packet of data.

5. The method of claim 4 , wherein the corresponding transmission schedule comprises an unused schedule entry, and execution of the instructions by the processor further re-transmits the at least one packet in accordance with the transmission parameter controls of the unused schedule entry.

6. The method of claim 4 , wherein the corresponding transmission schedule does not comprise an unused schedule entry, and execution of the instructions by the processor further provides feedback data indicating failed transmission of the at least one packet of data with respect to the at least one schedule entry associated with the failed transmission.

7. The method of claim 5 , further comprising receiving an acknowledgment of receipt of the re-transmitted at least one packet of data in accordance with the unused schedule entry.

8. The method of claim 7 , further comprising providing feedback data related to the re-transmission of the at least one packet of data in accordance with the at least one schedule entry associated with the acknowledged re-transmission.

9. The method of claim 3 , further comprising updating the at least one schedule entry of the corresponding transmission schedule according to the feedback data.

10. The method of claim 6 , further comprising updating the at least one schedule entry of the corresponding transmission schedule according to the feedback data.

11. The method of claim 8 , further comprising updating the at least one schedule entry of the corresponding transmission schedule according to the feedback data.
