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 selecting an antenna configuration corresponding to a next transmission of packet data, the method comprising:

executing instructions stored in memory, wherein execution of the instructions by a processor;

selects an antenna configuration for packet data transmission, wherein the packet data is transmitted at a transmitting station, and wherein the antenna configuration corresponds to a receiving station address,

selects an antenna configuration for packet data reception from the transmitting station; and

transmitting packet data to the receiving station address using the selected antenna configuration for packet data transmission,

wherein the antenna configuration for packet data reception is different than the antenna configuration for packet data transmission but otherwise corresponds to a known antenna configuration associated with optimizing receipt of packet data from the transmitting station.

2. The method of claim 1, wherein the selected antenna configuration reduces interference in the wireless link during packet data transmission to a remote receiving node.

3. The method of claim 1, wherein the selected antenna configuration corresponds to a maximum gain over a wireless link.

4. The method of claim 1, further comprising executing by a processor instructions stored in memory to update a link quality metric associated with a physical data rate or an antenna configuration.

5. The method of claim 1, further comprising executing by a processor instructions stored in memory to generate a transmission schedule including at least one schedule entry defining a set of parameter controls associated with the receiving station address.

6. The method of claim 5, further comprising executing by a processor instructions stored in memory to select a physical data rate for packet data transmission, the physical data rate corresponding to the rate at which the communication device converts the packet data for transmission via the antenna apparatus.

7. The method of claim 6, wherein the selected physical data rate is the maximum effective user data rate.

8. A non-transitory computer-readable storage medium having embodied thereon a program, the program being executable by a processor to perform a method for selecting an antenna configuration corresponding to a next transmission of packet data, the method comprising:

selecting an antenna configuration for packet data transmission, wherein the packet data is transmitted at a transmitting station, and wherein the antenna configuration corresponds to a receiving station address,

selecting an antenna configuration for packet data reception from the transmitting station; and

transmitting packet data to the receiving station address using the selected antenna configuration for packet data transmission,

wherein the antenna configuration for packet data reception is different than the antenna configuration for packet data transmission but otherwise corresponds to a known antenna configuration associated with optimizing receipt of packet data from the transmitting station.

9. The method of claim 8, wherein the selected antenna configuration reduces interference in the wireless link during packet data transmission to a remote receiving node.

10. The method of claim 8, wherein the selected antenna configuration corresponds to a maximum gain over a wireless link.

11. The method of claim 8, further comprising executing by a processor instructions stored in memory to update a link quality metric associated with a physical data rate or an antenna configuration.

12. The method of claim 8, further comprising executing by a processor instructions stored in memory to generate a transmission schedule including at least one schedule entry defining a set of parameter controls associated with the receiving station address.

13. The method of claim 12, further comprising executing by a processor instructions stored in memory to select a physical data rate for packet data transmission, the physical data rate corresponding to the rate at which the communication device converts the packet data for transmission via the antenna apparatus.

14. The method of claim 13, wherein the selected physical data rate is the maximum effective user data rate.
