First Claim
Patent Images
1. A method of processing data units in a mobile communications system, the method comprising:
- generating a first data unit by a first layer;
transferring the generated first data unit to a second layer; and
generating a second data unit using the first data unit by the second layer,wherein the second data unit includes at least one indicator to indicate whether at least one field exists in a header of the first data unit,wherein the at least one indicator comprises a header field existence indicator that is positioned in a first field of the second data unit, andwherein the at least one field is at least an L field, an SI field, an E field, or an LI field.

Abstract
A method for transmitting and receiving data between a base station and a terminal in an E-UMTS (Evolved Universal Mobile Telecommunications System) or an LTE (Long Term Evolution) system is disclosed. A header overhead of data transmitted from a wireless end can be minimized by adding a header field existence indicator indicating presence or absence of a header in an upper data block to a data block of a lower layer, to thus effectively use radio resources.

9. A method of processing data units in a mobile communications system, the method comprising:
-
receiving a first data unit from a lower layer; checking whether at least one header field existence indicator is included in the first data unit; and generating a second data unit following the checking, wherein the at least one header field existence indicator is positioned in a first field of the first data unit and indicates whether at least one field exists in a header of the second data unit, and wherein the at least one field is at least an L field, an SI field, an E field, or an LI field. - View Dependent Claims (10, 11)

12. A mobile terminal for processing data units in a mobile communications system, the mobile terminal comprising:
-
a first radio protocol entity configured to generate a first data unit and to transfer the generated first data unit to a second radio protocol entity; and the second radio protocol entity configured to generate a second data unit using the first data unit, wherein the second data unit includes at least one indicator to indicate whether at least one field exists in a header of the first data unit, wherein the at least one indicator comprises a header field existence indicator that is positioned in a first field of the second data unit, and wherein the at least one field is at least an L field, an SI field, an E field, or an LI field.
