Abstract

There may be provided a method for priory based transmission of skywave symbols, the method may include starting to transmit a first skywave symbol; determining to stop a transmission of the first skywave symbol and to transmit a second skywave symbol that has a higher priority than the first skywave symbol; stopping the transmission of first skywave symbol before a completion of the transmission of the first skywave symbol thereby transmitting a partial first skywave symbol; and transmitting the second skywave symbol.

Claims (27)

1. A method for priory based transmission of skywave symbols, the method comprises:

starting to transmit a first skywave symbol;

determining to stop a transmission of the first skywave symbol and to transmit a second skywave symbol that has a higher priority than the first skywave symbol;

stopping the transmission of first skywave symbol before a completion of the transmission of the first skywave symbol thereby transmitting a partial first skywave symbol; and

transmitting the second skywave symbol.

2. The method according to claim 1 comprising introducing a gap between the stopping of the transmission of the first skywave symbol and a start of the transmitting of the second skywave symbol.

3. The method according to claim 1 comprising transmitting the second skywave symbol without introducing a gap between the stopping of the transmission of the first skywave symbol and a start of the transmitting of the second skywave symbol.

4. The method according to claim 1 wherein each one of the second skywave symbol and the partial first skywave symbol comprises illegal subcarrier signals and legal subcarrier signals; wherein the transmission of the partial first skywave symbol is distinguishable from the transmittal of the second skywave symbol based on at least one energy parameters related to the legal and illegal subcarrier signals of the second skywave symbol and the partial first skywave symbol.

5. The method according to claim 1 wherein the determining is based on (a) a priority difference between the first and second skywave symbols, (b) a time gap between the starting of the transmission of the first skywave symbol and the determining, and (c) a length of the first skywave symbol.

6. The method according to claim 1 wherein the determining is based on (a) a priority difference between the first and second skywave symbols, and (b) a time gap between the starting of the transmission of the first skywave symbol and the stopping of the transmission of the partial first skywave symbol, and (c) a length of the first skywave symbol.

7. The method according to claim 1 comprising determining to stop the transmission of the first skywave symbol and to transmit the second skywave symbol when (a) a product of a multiplication of a constant by a length of the first skywave symbol exceeds (b) a time gap between the starting of the transmission of the first skywave symbol and the determining.

8. The method according to claim 1 comprising determining to stop the transmission of the first skywave symbol and to transmit the second skywave symbol when (a) a product of a multiplication of a constant by a length of the first skywave symbol exceeds (b) a time gap between the starting of the transmission of the first skywave symbol and the stopping of the transmission of the partial first skywave symbol.

9. The method according to claim 1 wherein the first and second skywave symbols are asynchronous skywave symbols.

10. The method according to claim 1 wherein the first and second skywave symbols are orthogonal frequency division multiplexing (OFDM) skywave symbols.

11. A non-transitory computer readable medium that stores instructions for:

starting to transmit a first skywave symbol;

determining to stop a transmission of the first skywave symbol and to transmit a second skywave symbol that has a higher priority than the first skywave symbol;

stopping the transmission of first skywave symbol before a completion of the transmission of the first skywave symbol thereby transmitting a partial first skywave symbol; and

transmitting the second skywave symbol.

12. The non-transitory computer readable medium according to claim 11 that stores instructions for introducing a gap between the stopping of the transmission of the first skywave symbol and a start of the transmitting of the second skywave symbol.

13. The non-transitory computer readable medium according to claim 11 that stores instructions for transmitting the second skywave symbol without introducing a gap between the stopping of the transmission of the first skywave symbol and a start of the transmitting of the second skywave symbol.

14. The non-transitory computer readable medium according to claim 11 wherein each one of the second skywave symbol and the partial first skywave symbol comprises illegal subcarrier signals and legal subcarrier signals; wherein the transmission of the partial first skywave symbol is distinguishable from the transmittal of the second skywave symbol based on at least one energy parameters related to the legal and illegal subcarrier signals of the second skywave symbol and the partial first skywave symbol.

15. The non-transitory computer readable medium according to claim 11 wherein the determining is based on (a) a priority difference between the first and second skywave symbols, (b) a time gap between the starting of the transmission of the first skywave symbol and the determining, and (c) a length of the first skywave symbol.

16. The non-transitory computer readable medium according to claim 11 wherein the determining is based on (a) a priority difference between the first and second skywave symbols, and (b) a time gap between the starting of the transmission of the first skywave symbol and the stopping of the transmission of the partial first skywave symbol, and (c) a length of the first skywave symbol.

17. The non-transitory computer readable medium according to claim 11 that stores instructions for determining to stop the transmission of the first skywave symbol and to transmit the second skywave symbol when (a) a product of a multiplication of a constant by a length of the first skywave symbol exceeds (b) a time gap between the starting of the transmission of the first skywave symbol and the determining.

18. The non-transitory computer readable medium according to claim 11 that stores instructions for determining to stop the transmission of the first skywave symbol and to transmit the second skywave symbol when (a) a product of a multiplication of a constant by a length of the first skywave symbol exceeds (b) a time gap between the starting of the transmission of the first skywave symbol and the stopping of the transmission of the partial first skywave symbol.

19. The non-transitory computer readable medium according to claim 11 wherein the first and second skywave symbols are asynchronous skywave symbols.
