Abstract

A system and method for implementing transmission parameter control at a transmitting station is described. The exemplary system and method comprises querying a transmission parameter control module for a transmission schedule. The transmission schedule comprises at least one schedule entry defining a set of transmission parameter controls as they pertain to a destination address. At least one packet of data is then transmitted to the destination address according to the transmission parameters controls of at least one schedule entry from the transmission schedule. A system and method for selecting an antenna configuration corresponding to a next transmission of packet data is also disclosed.

Claims

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 transmission schedule, the transmission schedule comprising at least one schedule entry defining a set of transmission parameter controls associated with a destination address; and

transmitting at least one packet of data to the destination address according to the transmission parameters controls of the at least one schedule entry from the 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 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 transmission schedule comprises an unused schedule entry and further comprising re-transmitting 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 transmission schedule does not comprise an unused schedule entry and further comprising providing 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 with respect to 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 entry of the transmission schedule according to the feedback data.

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

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

12. A system for transmission parameter control in a wireless network, the system comprising:

a processor configured to execute at least one program stored in memory, the at least one program comprising instructions for executing a transmission schedule, the transmission schedule comprising at least one schedule entry defining a set of transmission parameter controls associated with a destination address;

an antenna apparatus adjustable into a plurality of antenna configurations, each antenna configuration corresponding to a radiation pattern;

a communication device configured to implement at least one of a plurality of physical data rates as specified by the set of transmission parameter controls; and

an antenna element selector device configured to implement at least one of the plurality of antenna configurations of the antenna apparatus as specified by the set of transmission parameter controls,

the antenna apparatus further configured to transmit one or more data packets to the destination address in accordance with the at least one of the physical data rates and the at least one of the plurality of antenna configurations as specified by the set of transmission parameter controls of the transmission schedule executed by the processor.

13. A machine-readable storage medium having embodied thereon a program, the program being executable by a processor to perform a method for implementing transmission parameter control at a transmitting station, the method comprising:

querying a transmission parameter control module for a transmission schedule, the transmission schedule comprising at least one schedule entry defining a set of transmission parameter controls associated with a destination address;

configuring a communication device to implement at least one physical data rate as specified by the set of transmission parameter controls;

configuring an antenna apparatus to form a particular radiation pattern as specified by the set of transmission parameter controls; and

transmitting at least one packet of data to the destination address according to the set of transmission parameters controls of the at least one schedule entry from the transmission schedule.
