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 an initial packet data transmission, the antenna configuration corresponding to a particular station address, and

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

transmitting packet data to the particular station address using the selected antenna configuration for initial packet data transmission.

2. The method of claim 1, wherein the antenna configuration for packet data reception is the same configuration as the antenna configuration for packet data transmission.

3. The method of claim 1, 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 particular station address.

4. A system for selecting an antenna configuration corresponding to a next transmission of packet data, the system comprising:

a processor configured to control an antenna element selector device to select an antenna configuration, the selection of an antenna configuration associated with accessing a transmission schedule having transmission parameter control data for a remote receiving node;

a communication device configured to transmit packet data to the remote receiving node via an antenna apparatus in accordance with transmission parameters set forth in the transmission schedule;

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

an antenna element selector device configured to respond to instructions received from the processor regarding selecting an antenna configuration from the transmission schedule.

5. The system of claim 4, further comprising a transmission parameter control module stored in memory and executable by the processor to provide a transmission schedule to the antenna element selector device, the transmission schedule including at least one schedule entry defining a set of parameter controls associated with a destination address.

6. The system of claim 5, wherein the transmission parameter control module is further executable by the processor 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 system of claim 6, wherein the selected physical data rate is the maximum effective user data rate.

8. The system of claim 5, wherein the transmission parameter control module includes a probe scheduler executable by the processor to identify an unused antenna configuration or unused physical data rate based on predetermined criteria.

9. The system of claim 4, wherein the selected antenna configuration reduces interference in the wireless link during packet data transmission to a remote receiving node.

10. The system of claim 4, wherein the selected antenna configuration corresponds to a maximum gain over a wireless link.

11. The system of claim 4, further comprising a feedback module stored in memory and executable by the processor to update a link quality metric associated with a physical data rate or an antenna configuration.

12. A 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 an initial packet data transmission, the antenna configuration corresponding to a particular station address,

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

transmitting packet data to the particular station address using the selected antenna configuration for initial packet data transmission.
