Transmission and reception parameter control
View Patent ↗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.
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
tracks a packet inter-arrival time for at least one flow of data, the at least one flow of data being temporally periodic,
compiles a schedule of expected arrival times for the at least one flow of temporally periodic data, the schedule based on at least a prediction of subsequent arrival time of the tracked flow of data, and
selects an antenna configuration corresponding to the at least one flow of data prior to the expected arrival time of the at least one flow of temporally periodic data, the antenna configuration corresponding to a known antenna configuration associated with optimizing receipt of packet data from a particular station address of the packet.
2. A system for selecting an antenna configuration corresponding to a next transmission of packet data from a particular station, the system comprising:
a processor configured to execute at least one scheduling program stored in memory, the scheduling program including a transmission schedule comprising a plurality of schedule entries arranged based on transmission attempt results by the system to the particular station, each schedule entry in the plurality of schedule entries associated with an antenna configuration;
an antenna apparatus adjustable into each of the associated antenna configurations; and
an antenna element selector device configured to implement a particular antenna configuration from the associated antenna configurations for the antenna apparatus as determined by the scheduling program based on the arrangement of the schedule entries in the transmission schedule, the particular antenna configuration corresponding to optimization of reception of the next transmission of packet data from the particular station.
3. The system of claim 2 , wherein the scheduling program includes a packet pattern recognition program executable by the processor to select the particular antenna configuration based on when a subsequent sequence of data packets is expected from the particular station based on a number of transmitted packets by the system.
4. The system of claim 2 , wherein the scheduling program includes a cyclic redundancy check program executable by the processor to select the particular antenna configuration based on a media access control address of the particular station associated with the transmission schedule.
5. The system of claim 2 , wherein the scheduling program includes a temporal prediction program executable by the processor to select the particular antenna configuration based on an expected arrival time of at least one flow of temporally periodic data.
6. The system of claim 2 , wherein the scheduling program includes a last transmission program executable by the processor to select the particular antenna configuration for packet data reception from a particular station address associated with the particular station, the particular antenna configuration corresponding to an antenna configuration used to transmit data to the particular station address immediately preceding reception of the next transmission of packet data.
7. The system of claim 2 , wherein the scheduling program includes a last transmission program executable by the processor to select the particular antenna configuration for packet data reception from a particular station address associated with the particular station, the particular antenna configuration corresponding to an antenna configuration different than an antenna configuration used to transmit data to the particular station address immediately preceding reception of the next transmission of packet data but otherwise known to optimize receipt of packet data from the particular station address.
8. The system of claim 2 , wherein each schedule entry in the plurality of schedule entries is further associated with at least one of a physical layer data rate and a transmit power.
9. The system of claim 2 , wherein the scheduling program includes a plurality of transmission schedules, each transmission schedule in the plurality of transmission schedules associated with a corresponding station.
10. The system of claim 2 , wherein the execution of the scheduling program by the processor periodically updates the arrangement of the schedule entries in the transmission schedule in response to additional transmission attempt results.
11. The system of claim 2 , wherein the particular antenna configuration corresponds to a gain between the system and the particular station less than that of another antenna configuration in the associated antenna configurations.
12. The system of claim 2 , wherein the transmission attempt results for each schedule entry are based on feedback from the particular station indicating that the particular station received packet data transmitted by the system using the associated antenna configuration.
