Abstract
A radio communication system for a radio communication service and a terminal is provided, namely, a method for communicating data blocks between a base station and the terminal in Evolved Universal Mobile Telecommunications System (E_UMTS) or Long Term Evolution (LTE) System evolved from UMTS, and more particularly, to a method of effectively identifying a transmitter of a data block received by a receiver.
Claims7
A method of communicating data in wireless communication system, the method comprising steps of:
- transmitting a random access preamble;
- receiving a random access response in response to the transmitted random access preamble, wherein the random access response includes a radio resource allocation;
- and
- transmitting a protocol data unit (PDU) using the allocated radio resource,
- wherein the PDU includes a terminal identifier and logical channel ID (LCID) fields,
- wherein at least one field of the PDU is used to indicate an existence of the terminal identifier,
- wherein the at least one field is a particular field of the LCID fields,
- wherein the LCID fields are used to identify a logical channel or a type of control information,
- wherein the at least one field comprises a specific value identifying the existence of the terminal identifier, and
- wherein the specific value is indicated by 5 bits.
A method of generating a protocol data unit (PDU) in wireless communication system, the method comprising steps of:
- transmitting a random access preamble;
- receiving a random access response in response to the transmitted random access preamble, wherein the random access response includes a radio resource allocation;
- generating the PDU with a header,
- wherein the generated PDU includes a terminal identifier,
- wherein the header includes logical channel ID (LCID) fields,
- wherein the LCID fields are used to identify a logical channel or used to identify a type of control information,
- wherein at least one field is used to indicate an existence of the terminal identifier,
- wherein the at least one field is a particular field of the LCID fields,
- wherein the at least one field comprises a specific value identifying the existence of the terminal identifier, and
- wherein the specific value is indicated by 5 bits;
- and
- transmitting the generated PDU using the allocated radio resource.
