Abstract

A method for operating an RLC entity and a MAC entity in a Universal Mobile Telecommunications System (UMTS), the European IMT-2000 system. A format of a MAC-has PDU is optimized in a MAC-hs entity, so that a large number of users can be supported with using less resources when a VoIP service is provided in one cell.

Claims

1. A method of processing data units in a mobile communications system, the method comprising:

receiving a plurality of size information for a first data unit from a first entity; and

generating the first data unit from at least one second data unit, wherein a size of the first data unit is configured depending on the received one of the plurality of size information for the first data unit.

2. The method of claim 1, wherein the first entity is a Radio Resource Control (RRC) entity.

3. The method of claim 1, wherein the size of the configured first data unit is selected from the plurality of size information.

4. The method of claim 3, wherein the size of the configured first data unit is selected from the plurality of size information based on a assigned radio resource.

5. The method of claim 1, wherein the first data unit is a Radio Link Control (RLC) Protocol Data Unit (PDU) and the second data unit is a RLC Service Data Unit (SDU).

6. The method of claim 1, wherein the first data unit includes at least one of user data and control information.

7. The method of claim 1, further comprising:

transferring the first data unit to a second entity.

8. The method of claim 7, wherein the first data unit is transferred to the second entity via a logical channel.

9. The method of claim 7, wherein the second entity is a Medium Access Control (MAC) entity.

10. The method of claim 9, wherein the MAC entity generates a third data unit which includes the first data unit.

11. The method of claim 10, wherein the third data unit is a MAC-hs PDU or a MAC-e PDU.

12. A method of processing data units in a mobile communications system, the method comprising:

receiving a plurality of first data units from a first entity, wherein the plurality of the first data units have variable sizes; and

generating a second data unit from the received plurality of the first data units, wherein the second data unit includes the plurality of the first data units having variable sizes.

13. The method of claim 12, further comprising:

transmitting, to the first entity, information of a size of each first data unit and a number of first data units.

14. The method of claim 12, wherein the first data units are Radio Link Control (RLC) Protocol Data Units (PDUs) and the second data unit is either a MAC-hs PDU or a MAC-e PDU.

15. The method of claim 12, wherein the first entity is a Radio Link Control (RLC) entity.

16. The method of claim 12, wherein the first data units are transferred from the first entity within a same time period.

17. The method of claim 16, wherein the time period is a Transmission Time Interval.
