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 Radio Link Control (RLC) Protocol Data Unit (PDU) from a Radio Resource Control (RRC) entity;

generating the RLC PDU from at least one RLC Service Data Unit (SDU), wherein a size of the RLC PDU is configured depending on the received one of the plurality of size information for the RLC PDU; and

transferring the RLC PDU to a Medium Access Control (MAC) entity,

wherein the RLC PDU is transferred to the MAC entity via a logical channel,

wherein the MAC entity generates a MAC-hs PDU including the RLC PDU,

wherein the generated MAC-hs PDU corresponds to a specific queue used for a Voice over Internet Protocol (VoIP) service,

wherein a size of each header field of the MAC-hs PDU is set by the specific queue,

wherein a Size Index Identifier (SID) field of the MAC-hs PDU is set to have a length of 4 bits or 5 bits in the specific queue,

wherein a Number (N) field is not included in the header field of the MAC-hs PDU, and

wherein a number of bits of a Transmission Sequence Number (TSN) of the MAC-hs PDU is set to have a length of 3 bits.

2. The method of claim 1, wherein the size of the configured RLC PDU is selected from the plurality of size information.

3. The method of claim 2, wherein the size of the configured RLC PDU is selected from the plurality of size information based on an assigned radio resource.

4. The method of claim 1, wherein the RLC PDU includes at least user data or control information.
