Method and system for communicating to radio frequency integrated circuit
View Patent ↗A method and system for managing change-over in radio functionality at a radio front-end in a Time Division Duplexing (TDD) system is provided. The method comprises storing one or more control commands. The one or more control commands may correspond to the change-over. The change-over may be a transmitter-to-receiver change-over or a receiver-to-transceiver change-over. The method further comprises receiving a trigger time corresponding to the one or more control commands. The trigger time comprises a timing requirement for the change-over. Thereafter, one or more control commands are released based on a predetermined condition.
1. A method for managing change-over in radio functionality at a radio front-end in a Time Division Duplexing (TDD) system, the method comprising:
a. storing at least one control command;
b. receiving a trigger time corresponding to the at least one control command, wherein the trigger time corresponds to a timing requirement, the timing requirement being base at least in part on a time required by physical components of the radio front-end to settle down after a change-over is initialized; and
c. releasing the at least one control command based on a predetermined condition, wherein the change-over occurs in response to the releasing, wherein the at least one control command corresponds to the change-over, the change-over being at least one of a transmitter-to-receiver change-over and a receiver-to-transmitter change-over, wherein the predetermined condition comprises matching a count of a counter module with the trigger time at predetermined intervals of time, the count of the counter module being incremented at the predetermined intervals of time, wherein the at least one control command is released, if the trigger time matches the count of the counter module.
2. The method of claim 1 , wherein the timing requirement comprises one of a change-over time and a predetermined time subtracted from the change-over time.
3. The method of claim 1 , wherein the counter module is reset in response to releasing the at least one control command.
4. The method of claim 1 , wherein the releasing comprises at least one of
a. communicating the at least one control command from a baseband processing function to an RF processing function; and
b. communicating the at least one control command from the RF processing function to the baseband processing function.
5. The method of claim 1 , wherein the at least one control command comprises one or more control command words.
6. The method of claim 1 , wherein the at least one control command is stored in a first-in-first-out (FIFO) queue.
7. The method of claim 1 , wherein the at least one control command is stored in non-real time.
8. The method of claim 1 , wherein the at least one control command corresponds to a predetermined set of control commands.
9. A method for reducing change-over overhead of a radio front-end in a Time Division Duplexing (TDD) system, the method comprising:
a. receiving at least one control command, the at least one control command corresponding to a change-over, the change-over being at least one of a transmitter-to-receiver change-over and a receiver-to-transmitter change-over;
b. obtaining a trigger time corresponding to a timing requirement for the change-over; wherein the timing requirement is base at least in part on a time required by physical components of the radio front-end to settle down after a change-over is initialized:
c. matching the trigger time to a count of a counter; and
d. releasing the at least one control command, if the trigger time matches the count of the counter, wherein the change-over occurs in response to the releasing.
10. The method of claim 9 , wherein the trigger time is matched with the count of the counter at predetermined intervals of time, wherein the count of the counter is incremented at the predetermined intervals of time.
11. A system for managing change-over in radio functionality at a radio front-end in a Time Division Duplexing (TDD) system, the system comprising:
a. a storing module, the storing module configured for:
i. storing at least one control command; and
ii. saving a trigger time corresponding to the at least one control command wherein the trigger time corresponds to a timing requirement, wherein the timing requirement is base at least in part on a time required by physical components of the radio front-end to settle down after a change-over is initialized,
b. a counting module, the counting module configured for:
i. maintaining a counter based on the trigger time; and
ii. incrementing a count of the counter at predetermined intervals of time;
c. a matching module, the matching module matching the count of the counter with the trigger time at each predetermined interval of time; and
d. a releasing module, the releasing module releasing the at least one control command from the storing module, if the trigger time matches the count of the counter; wherein
the at least one control command corresponds to a change-over, the change-over being at least one of a transmitter-to-receiver change-over and a receiver-to-transmitter change-over.
12. The system of claim 11 , wherein the trigger time corresponds to a timing requirement for the change-over.
13. The system of claim 11 , wherein the counting module is configured to reset the counter, if the at least one control command is released from the storing module.
14. The system of claim 11 , wherein the storing module is configured for storing the at least one control command in a first-in-first-out (FIFO) queue.
