Abstract

A method for increasing throughput capacity of a mobile station transmitting a plurality of consecutive bursts to a base station in a communication system is disclosed. The first burst is transmitted using a normal burst format while succeeding consecutive bursts are transmitted using an auxiliary burst format wherein the auxiliary bursts contain larger data fields than normal bursts.

Claims

1. A method for increasing throughput capacity of a mobile station transmitting a plurality of bursts to a base station in a communication system, comprising the steps of:

transmitting a first burst using a first burst format including at least one first data field having a first number of bits;

transmitting succeeding bursts using a second format including at least one second data field having a second number of bits greater than said first number of bits, said at least one second data field including third and fourth data fields and said second format including a synchronization field.

2. A method according to claim 1, wherein said mobile station is operating in a small cell.

3. The method of claim 1, wherein said at least one first data field comprises two first data fields, said first number of bits is 244 bits, said at least one second data field comprises two second data fields and said second number of bits is 296 bits.

4. A method for increasing throughput capacity of a mobile station transmitting a plurality of consecutive bursts to a base station in a communication system, comprising the steps of:

transmitting a first burst using a first burst format;

transmitting succeeding consecutive bursts except a last burst of said plurality of consecutive bursts using a second burst format; and

transmitting the last burst using a third burst format wherein each of said first, second and third burst formats are different.

5. A method according to claim 4, wherein said mobile station is operating in a large cell.

6. A method according to claim 4, wherein said second format is comprised of first and second data fields and a synchronization field.

7. The method of claim 4, wherein said first burst format includes at least one first data field having a first number of bits and said second burst format includes at least one second data field having a second number of bits greater than said first number of bits.

8. The method of claim 7, wherein said at least one first data field comprises two first data fields, said first number of bits is 244 bits, said at least one second data field comprises two second data fields and said second number of bits is 296 bits.

9. A method for transmitting data from a mobile station to a base station in a communication system, comprising the steps of:

transmitting data from the mobile station to the base station in bursts, wherein said bursts can be in different formats;

receiving said bursts at said base station;

determining the format for each burst by detecting the presence or absence of various physical layer fields in said received burst wherein said physical layer fields include guard, ramp, preamble, and additional synchronization fields; and

decoding the data contained in each received burst based on the determined format.

10. A method according to claim 9, wherein said different formats include a first burst format and a second burst format.

11. A mobile station comprising:

a processor for determining whether said mobile station is to transmit at greater than full-rate, and, if so, grouping information in a first burst and succeeding bursts; and

a transmitter for transmitting a first burst using a first burst format; and

for transmitting succeeding consecutive bursts using a second burst format different than said first burst format.

12. The mobile station of claim 11, wherein said first burst format includes at least one first data field having a first number of bits and said second burst format includes at least one second data field having a second number of bits greater than said first number of bits.

13. The mobile station of claim 12, wherein said at least one first data field comprises two first data fields, said first number of bits is 244 bits, said at least one second data field comprises two second data fields and said second number of bits is 296 bits.

14. A method for transmitting data from a mobile station to a base station in a communication system, comprising the steps of:

transmitting data from the mobile station to the base station in bursts, wherein said bursts can be in several different formats;

receiving said bursts at said base station;

determining the format for each burst based upon information received from a reverse channel scheduling section of said base station; and

decoding the data contained in each received burst based on the determined format.

15. A method according to claim 14, wherein said different formats include a first burst format and a second burst format.

16. The method of claim 15, wherein said first burst format includes at least one first data field having a first number of bits and said second burst format includes at least one second data field having a second number of bits greater than said first number of bits.

17. The method of claim 16, wherein said at least one first data field comprises two first data fields, said first number of bits is 244 bits, said at least one second data field comprises two second data fields and said second number of bits is 296 bits.

18. A method for transmitting data from a mobile station to a base station in a communication system, comprising the steps of:

transmitting data from the mobile station to the base station in a burst, wherein said burst can be in one of a plurality of different formats;

receiving said burst at said base station;

decoding the data contained in said burst according to a plurality of burst formats; and

selecting one of the plurality of differently decoded versions of said bursts by determining which decoded data has a correct cyclic redundancy check.

19. A method according to claim 18, wherein said different formats include a first burst format and a second burst format.

20. The method of claim 19, wherein said first burst format includes at least one first data field having a first number of bits and said second burst format includes at least one second data field having a second number of bits greater than said first number of bits.

21. The method of claim 20, wherein said at least one first data field comprises two first data fields, said first number of bits is 244 bits, said at least one second data field comprises two second data fields and said second number of bits is 296 bits.

22. A base station comprising:

means for receiving a burst of data formatted according to one of a plurality of different formats, a first format having at least one data field having 244 bits and a second format having at least one data field having 296 bits;

means for determining a format of said received burst of data by detecting a presence or absence of at least one predetermined physical field in said received burst of data; and

means for decoding said received burst of data using said determined format.

23. A base station comprising:

means for receiving a burst of data formatted according to one of a plurality of different formats;

means for decoding said received burst using each of said plurality of different formats; and

means for selecting one of said decoded versions of said received burst that has a correct cyclic redundancy check.

24. The base station of claim 23, wherein said different formats include a first burst format and a second burst format.

25. The base station of claim 23, wherein said first burst format includes at least one first data field having a first number of bits and said second burst format includes at least one second data field having a second number of bits greater than said first number of bits.
