Abstract

In a method of transmitting information at high speed by allocation of multiple bursts within a transmission frame each including information symbols and system symbols a user is allocated a plurality of adjacent bursts and at least one of the system symbols between the information symbols of the first of the adjacent bursts and the information symbols of the last of the adjacent bursts is replaced with an information symbol to form a superburst. The associated receiving method includes a stage for recognizing reception of a superburst and a stage for processing the superburst to extract the information symbols from it. There are applications relating to transmission and reception equipments of mobile radio communication systems.

Claims

1. A method of transmitting information to a receiver at high speed by allocation of multiple bursts within a transmission frame, each of said bursts including information symbols and system symbols, the method including the steps of:

allocating to a user a plurality of adjacent bursts; and

replacing at least one system symbol of said adjacent bursts with an information symbol to form a superburst.

2. The method according to claim 1, further including the step of advising the receiver of an imminent transmission of superbursts by transmitting information representing a configuration of said superbursts.

3. The method according to claim 2, wherein the advising step is executed prior to transmission of a superburst and said advising step includes transmitting the information in a specific burst, said information containing an indication of a number of bursts concatenated in said superburst.

4. The method according to claim 2, wherein the information includes indication of a number of frames in which superbursts are used.

5. The method according to claim 2, wherein each of said superbursts has a configuration which is known in advance by the receiver, each configuration being associated with a configuration number, wherein said information contains the configuration number corresponding to the configuration of superbursts to be transmitted.

6. The method according to claim 1, wherein each of said adjacent bursts includes information symbols and system symbols known to the receiver, said system symbols including start symbols, end symbols and a learning sequence, and wherein the learning sequences and the information symbols of each of said adjacent bursts are rearranged so that said superburst includes a single learning sequence.

7. The method according to claim 6, further including the step of advising the receiver of an imminent transmission of superbursts by transmitting information representing a configuration of a superburst including a number of said adjacent bursts concatenated in the superburst, a location of the single learning sequence within the superburst and a length of said single learning sequence.

8. The method according to claim 7, wherein said single learning sequence includes L guard symbols followed by P reference symbols followed by L guard symbols, and said information further includes positive values for P and L.

9. The method according to claim 7, wherein said single learning sequence includes L guard symbols followed by P reference symbols followed by L guard symbols, and said information further includes a reference number giving positive values for P and L.

10. The method according to claim 7, wherein the advising step is executed prior to transmission of a superburst and said advising step includes transmitting the information in a specific burst.

11. The method according to claim 7, wherein the information transmitted during the advising step further includes an indication of a number of frames in which superbursts are used.

12. The method according to claim 7, wherein each of said superbursts has a configuration which is known in advance by the receiver, each configuration being associated with a configuration number, wherein said information contains the configuration number corresponding to the configuration of superbursts to be transmitted.

13. The method according to claim 1 wherein the number of adjacent bursts allocated to the same user within a transmission frame is equal to two.

14. The method according to claim 1, wherein the transmission frame is a Time Division Multiple Access frame.

15. A method of receiving information transmitted at high speed by allocation of multiple bursts within a transmission frame associated with a method of transmitting information at high speed by allocation of multiple bursts within a transmission frame, each of said bursts including information symbols and system symbols, the transmitting method including the steps of:

allocating to a user a plurality of adjacent bursts; and

replacing at least one system symbol of said adjacent bursts with an information symbol to form a superburst, the receiving method including the steps of;

recognizing reception of said superburst; and

, in the event that said superburst is recognized, processing said superburst and extracting said information symbols therefrom.

16. The method according to claim 15, wherein the transmission frame is a Time Division Multiple Access frame.

17. A method of receiving information transmitted at high speed by allocation of multiple bursts within a transmission frame, each burst initially including information symbols and a learning sequence, associated with a method of transmitting information at high speed by allocation of multiple bursts within a transmission frame, each of said bursts including information symbols and system symbols, the transmitting method including the steps of:
