Abstract

A method for processing multiple data services over a communications link between a mobile station and a base station is disclosed. A RLC/MAC protocol layer of the communications link between a mobile station and a base station receives a plurality of radio bearer services each including at least one service provided by the mobile station. The plurality of radio bearer services are processed in such a manner that services having substantially similar quantity of signal requirements are combined for transmission on a single logical channel. Data within the transmission blocks may be prioritized to enable flexible control of transmission rates.

Claims

1. A method for processing multiple data services over a communications link between a mobile station and a base station, comprising the steps of:

receiving a plurality of radio bearer services, each of the plurality of radio bearer services supporting at least one service;

separating data within the radio bearer services into a plurality of portions; and

multiplexing portions from at least two of the plurality of radio bearer services having substantially similar Quality of Service requirements into transmission blocks of the single logical channel on the communications link, wherein a number of the portions per transmission block is variable.

2. The method of claim 1 further including the step of:

prioritizing the portions from different radio bearer services such that high priority portions are transmitted prior to lower priority the portions without altering a transmission rate of the single logical channel.

3. The method of claim 2, wherein the plurality of portions comprise radio link control/medium access control protocol data units.

4. The method of claim 2 further including the step of:

scheduling the transmission of transmission blocks such that an output power of a transceiver remains below a predetermined level.

5. The method of claim 4, wherein the predetermined level may vary in time.

6. The method of claim 2, wherein the prioritizing is done by the mobile station.

7. The method of claim 2, wherein the prioritizing is done by the base station.

8. The method of claim 1 further comprising the step of mapping the logical channels onto physical channels.

9. A method for processing multiple data services over a communications link between a mobile station and a base station, comprising the steps of:

receiving a plurality of radio bearer services, each of the plurality of radio bearer services supporting at least one service;

separating data within the radio bearer services into a plurality of data blocks;

multiplexing data blocks from at least two of the plurality of radio bearer services having substantially similar Quality of Service requirements into transmission blocks of a single logical channel on the communications link, wherein the number of data blocks per transmission block is variable;

prioritizing the data blocks from different radio bearer services such that high priority data blocks are transmitted prior to lower priority data blocks without altering a transmission rate of the single logical channel; and

transmitting the transmission blocks on the single logical channel.

10. The method of claim 9 further including the step of:

scheduling the transmission rates of different logical channels such that an output rate of a transceiver remains below a predetermined level.

11. The method of claim 9 further including the step of:

scheduling the transmission of transmission blocks on the logical channel such that an output power of a transceiver remains below a predetermined level.

12. The method of claim 11, wherein the predetermined level may vary in time.

13. The method of claim 9, wherein the prioritizing is done by the mobile station.

14. The method of claim 9, wherein the prioritizing is done by the base station.

15. A method for processing multiple data services over a communications link between a mobile station and a base station, comprising the steps of:

receiving a plurality of radio bearer services, each of the plurality of radio bearer services supporting at least one service;

separating data within the radio bearer services into a plurality of data blocks;

combining the data blocks from radio bearer services having substantially similar Quality of Service requirements into transmission blocks of a single logical channel, wherein the number of data blocks per transmission blocks is variable;

scheduling the transmission of transmission blocks such that an output power of a transceiver remains below a predetermined level; and

transmitting the transmission blocks on the single logical channel.

16. The method of claim 15, wherein the predetermined level may vary in time.

17. The method of claim 15 further including the step of:

prioritizing radio link control/medium access control protocol data units from different radio bearers such that high priority radio link control/medium access control protocol data units are transmitted prior to lower priority radio link control/medium access control protocol data units without altering a transmission rate.

18. The method of claim 17, wherein the prioritizing is done by the mobile station.

19. The method of claim 17, wherein the prioritizing is done by the base station.
