MAC-es protocol data units (PDUS) including data of an upper layer and a control service data unit (SDU) including control information of a MAC layer are multiplexed and contained in a MAC-e protocol data unit (PDU) transmitted in an uplink from the UE during one transmission period. In a header of the MAC-e PDU, a header part corresponding the control SDU contains a data description indicator (DDI) field set as a specific value representing that the control information is transmitted, and a header part corresponding to the MAC-es PDU contains a DDI field which represents a MAC-e flow and a logical channel relating to uplink packet data included in the second PDU, and a data size. Node B detects the control information from the control SDU based on the DDI field set as the specific value. Since the header part representing the control information has a structure similar to the header part representing the MAC-es PDU, the structure of the header is simplified, and the header size of the packet is minimized.

Although it is not shown, MAC-es PDUs including RLC PDUs created from the RLC entities 405 may be transmitted to the multiplexing and TSN setting unit 430. The multiplexing and TSN setting unit 430 sets a multiplexing identifier, an N field, and an F field in each of header parts corresponding to the MAC-es PDUs, based on the size and/or the number of the RLC PDUs. In step 630, the multiplexing and TSN setting unit 430 configures a MAC-e PDU by concatenating the MAC-e header including the MAC-e header parts, the MAC-e control SDU, and the MAC-es PDUs, and then transmits the MAC-e PDU to the Node B 437 through the HARQ entity 435 and logical layer. If there is no MAC-es PDU to be transmitted, a MAC-e PDU including only the MAC-e control SDU is transmitted. FIG. 7 is a flowchart illustrating the operation of the Node B 437 according to the first exemplary implementation of an embodiment of the present invention. In step 705, the Node B 437 receives a MAC-e PDU including a MAC-e header and a MAC-e payload from the UE 402, and inputs the received MAC-e PDU to the demultiplexing unit 455. In step 710, the demultiplexing unit 455 analyzes the MAC-e header of the MAC-e PDU, and divides the MAC-e payload included in the MAC-e PDU into MAC-es PDUs. The demultiplexing unit 455 checks multiplexing identifiers for each of the MAC-es PDUs. Step 725 is performed if there is a multiplexing identifier having the Mux_id_control which is a predetermined special value, and if not, then step 720 is performed. When a multiplexing identifier is not identical to the Mux_id_control, a relevant MAC-es PDU is a general MAC-es PDU configured with TSN and RLC PDUs. Therefore, in step 720, the general MAC-es PDU is transmitted to the RNC 462. In contrast, when a multiplexing identifier is identical to the Mux_id_control, a relevant MAC-es PDU is a MAC-e control SDU including MAC-e control information. Therefore, in step 725, the MAC-e control SDU is transmitted to the E-DCH reception control unit 445. The E-DCH reception control unit 445 reads control information included in the MAC-e control SDU, and performs appropriate operations such as an operation for transmitting the control information to a scheduler. Exemplary Embodiment 2 According to the first exemplary implementation of an embodiment of the present invention, a multiplexing identifier included in a MAC-e header of a MAC-e PDU is used to identify a logical channel, a reordering queue, and an RLC PDU size. Different from the first embodiment, the second exemplary implementation of an embodiment of the present invention uses a data description indicator (DDI) in order to identify a MAC-d flow instead of the reordering queue. The combination of a logical channel, a reordering queue, and an RLC PDU size is identical to the combination of a logical channel, a MAC-d flow, and an RLC PDU size, in view that both include information about the size of RLC PDUs contained in a MAC-es PDU and information about an upper layer to which the RLC PDUs will be transmitted. The second exemplary implementation of an embodiment of the present invention uses a DDI, which is a logical identifier for identifying a logical channel, a MAC-d flow, and an RLC PDU size, in order to represent a MAC-e control SDU. One of the DDI values may take the place of the F field. As described above, the F field acts as a flag for representing whether the following field is a new MAC-e header part or a MAC-e payload. When a predetermined value (for example, �111111�) is allocated as a special DDI value, the special DDI value represents the end of a MAC-e header for distinguishing a MAC-e header from a MAC-e payload. FIG. 8 is a block diagram illustrating the structure of a MAC-e PDU using a special DDI value. A MAC-e PDU 835 is a data provided through a transmission channel to a physical layer, and includes a MAC-e header 840 and a MAC-e payload 845. The MAC-e payload 845 of the MAC-e PDU 835 includes MAC-es PDUs 850, each of which contains a TSN and a plurality of RLC PDUs. �k� number of header parts 805, 810, and 815 of the MAC-e header 840 one-to-one correspond to components included in the MAC-e payload 845. The MAC-e header part #1 805 corresponding to a first MAC-es PDU 850 is configured with a DDI field 820 (which represents a logical channel, a reordering queue, and an RLC PDU size) and an N field 825 for representing the number of RLC PDUs. Similarly, the MAC-e header part #2 810 is configured with a DDI field an N field for the next MAC-es PDU. The DDI field 830 of the kth header part 815 (which is the last part) is set as a special DDI value, i.e. �111111�, as described above, in order to represent the end of the MAC-e header 840. Predetermined parts of the MAC-e payload corresponding to the special DDI value can be padded with padding bits 855. That is, the special DDI value represents that an RLC PDU may not exist in the predetermined part of the MAC-e payload 845 corresponding to the DDI field 830. In addition, the special DDI value may be used to represent whether or not there is control information. According to another exemplary embodiment of the present invention, the DDI field 830 may be set as a specific value representing that a predetermined part of the MAC-e payload corresponding to the DDI field 830 is padded, or may be set as another specific value representing that the predetermined portion of the MAC-e payload corresponding to the DDI field 830 is control information. However, the following exemplary description assumes that one special DDI value represents a padding or control information. In this exemplary implementation, padding bits are regarded as a kind of control information. FIG. 9 is a block diagram illustrating the structure of a MAC-e PDU according to the second exemplary implementation of an embodiment of the present invention. A MAC-e PDU 940 includes a MAC-e header 945 and a MAC-e payload 950, and the MAC-e header 945 includes k number of header parts 905, 910, and 915. The header parts 905 to 915 one-to-one correspond to components included in the MAC-e payload 950. The MAC-e header part #1 905 corresponding to a first MAC-es PDU 955 is configured with a DDI field 920 (which represents a logical channel, a MAC-d flow, and an RLC PDU size) and an N field 925 for representing the number of RLC PDUs. Similarly, the MAC-e header part #2 910 is configured with a DDI field an N field for the next MAC-es PDU. The DDI field 930 of the kth header part 915 (which is the last part) is set as a special DDI value, e.g. �111111�, in order to represent that a relevant portion in the MAC-e payload contains a MAC-e control SDU 960. The N field of the last header part 915 is not used. The special DDI value represents a MAC-e control SDU which includes padding bits or MAC-e control information. The MAC-e control information is scheduling information used as a reference when the scheduler of the Node B performs scheduling. For instance, the MAC-e control information includes power information about a transmission power margin of a UE, or buffer status information of the UE. The transmission power margin represents the maximum available transmission power of a UE. A UE, which makes communication through a dedicated channel, always transmits pilot bits, a transport format combination indicator (TFCI), or the like through a dedicate physical control channel (DPCCH). Therefore, an available transmission power of a UE is obtained by subtracting the transmission power for the DPCCH from the total transmission power. Since the DPCCH is power controlled, the transmission power margin becomes smaller as the radio channel environment of the UE becomes more poor. Therefore, the scheduler of the Node B estimates the radio channel environment of the UE by using the transmission power margin. The buffer status information of a UE represents the amount of data stored in the buffer of the UE. The structure of the MAC-e control SDU 960, into which MAC-e control information is inserted, will now be described. Type fields 965, 970, and 975 are inserted into the MAC-e control SDU 960. The type fields 965, 970, and 975 represent kinds of control information inserted into the MAC-e control SDU 960. For instance, type 0 may represent padding, type 1 represent power information, and type 2 represent buffer status information. The MAC-e control SDU 960 is configured with the remaining portion of the MAC-e PDU 940, except for the MAC-e header 945 and MAC-es PDUs, so the size of the MAC-e control SDU 960 is variable. Since control information has a predetermined size, the remaining portion of the MAC-e control SDU 960, after the type information and the control information are inserted into the MAC-e control SDU 960, may be filled with padding bits. Padding bits are inserted into a 0-type MAC-e control SDU 965. Power information 980 (and padding bits if it is required) is inserted into a 1-type MAC-e control SDU 970. A buffer status report (BSR) 985 representing a buffer status (and padding bits if it is required) is inserted into a 2-type MAC-e control SDU 975. Although only three forms of type are disclosed above, more forms of type may be used according to the kinds of control information inserted into the MAC-e control SDU 960. For instance, a new type for representing control information including both of the power information and the buffer status information may be added. As described above, the second exemplary embodiment uses one of DDI values in order to represent whether or not control information is included. Since the second exemplary embodiment additionally uses an N field and an F field, differently from the first exemplary embodiment, it is possible to prevent waste of transmission resources. The system, to which the second embodiment of the present invention is applied to, has the same structure as the system shown in FIGS. 4A and 4B. The operations of the UE 402 and the Node B 437 will now be described with reference to FIGS. 4A and 4B. FIG. 10 is a flowchart illustrating the operation of the UE 402 according the second exemplary implementation of an embodiment of the present invention. In step 1005, the E-DCH transmission control unit 425 of the UE 402 triggers the transmission of MAC-e control information. In step 1010, the E-DCH transmission control unit 425 configures a MAC-e control SDU with the MAC-e control information, and transmits the MAC-e control SDU to the multiplexing and TSN setting unit 430. In this case, the MAC-e control SDU includes type information and control information as shown in FIG. 9. The MAC-e control SDU may be configured with information other than the above-mentioned information. In step 1015, the multiplexing and TSN setting unit 430 sets the value of a DDI field of a MAC-e header part corresponding to the MAC-e control SDU as a predetermined value, i.e. as a special DDI value. Although it is not shown, MAC-es PDUs including RLC PDUs created from the RLC entities 405 may be transmitted to the multiplexing and TSN setting unit 430. The multiplexing and TSN setting unit 430 sets a multiplexing identifier, a DDI field, and an N field for each of header parts corresponding to the MAC-es PDUs, based on the size and the number of the RLC PDUs. A header part corresponding to the MAC-e control SDU is configured as a DDI field. In step 1020, the multiplexing and TSN setting unit 430 configures a MAC-e PDU by concatenating the MAC-e header including the MAC-e header parts, the MAC-es PDUs, and the MAC-e control SDU, and then transmits the MAC-e PDU to the Node B 437 through the HARQ entity 435 and logical layer. If there is no MAC-es PDU to be transmitted, a MAC-e PDU including only the MAC-e control SDU is transmitted. FIG. 11 is a flowchart illustrating the operation of the Node B 437 according to the second exemplary implementation of an embodiment of the present invention. In step 1105, the Node B 437 receives a MAC-e PDU including a MAC-e header and a MAC-e payload from the UE 402, and inputs the received MAC-e PDU to the demultiplexing unit 455. In step 1110, the demultiplexing unit 455 analyzes the MAC-e header of the MAC-e PDU, and divides the MAC-e payload included in the MAC-e PDU into MAC-es PDUs. The demultiplexing unit 455 checks DDI fields for each of the MAC-es PDUs. Step 1125 is performed if there is a DDI field having a special DDI value, and if not, then step 1120 is performed. When a DDI field is not identical to the special DDI value, a relevant MAC-es PDU is a general MAC-es PDU configured with TSN and RLC PDUs. Therefore, in step 1120, the MAC-es PDU is transmitted to the RNC 462. In contrast, when a DDI field is identical to the special DDI value, a relevant MAC-es PDU is a MAC-e control SDU including MAC-e control information. Therefore, in step 1125, the MAC-e control SDU is transmitted to the E-DCH reception control unit 445. The E-DCH reception control unit 445 reads MAC-e control information included in the MAC-e control SDU based on a type value included in the MAC-e control SDU, and performs appropriate operations such as an operation for transmitting the control information to a scheduler. Exemplary Embodiment 3 According to the first exemplary embodiment, a special DDI value representing a MAC-e control SDU is used for a DDI field, and an N field relating to the DDI field is used to represent a kind of control information inserted into the MAC-e control SDU. FIG. 12 is a block diagram illustrating the structure of a MAC-e PDU according to the third exemplary implementation of an embodiment of the present invention. A MAC-e PDU 1240 includes a MAC-e header 1245 and a MAC-e payload 1250, and the MAC-e header 1245 includes k number of header parts 1205, 1210, and 1215. The header parts 1205 to 1215 one-to-one correspond to components included in the MAC-e payload 1250. The MAC-e header part #1 1205 corresponding to a first MAC-es PDU 1255 is configured with a DDI field 1220 (which represents a logical channel, a MAC-d flow, and an RLC PDU size) and an N field 1225 for representing the number of RLC PDUs. The MAC-e header part #2 1210 is configured with a DDI field an N field for the next MAC-es PDU. Similarly, the kth header part 1215 (which is the last part) is configured with a DDI field 1230 an N field 1235. The DDI field 1230 is set as a special DDI value, e.g. �111111�, in order to represent that a relevant portion in the MAC-e payload contains a MAC-e control SDU 1260. The special DDI value represents a MAC-e control SDU including MAC-e control information. The MAC-e control information represents power information of a UE, buffer status information of the UE, and so on. The N field 1235 of the kth header part 1215 represents kinds of the MAC-e control information. For instance, predetermined values, for example, as �0� for padding, �1�: for power information, �2� for buffer status information, and so on, may be used as values of N field 1235 relating to the DDI field 1230. MAC-e control information is inserted into the MAC-e control SDU 1260, except for a type field. For instance, in the case of type 0, padding bits are inserted into the MAC-e control SDU 1260. In the case of type 1, power information 1270 (and padding bits if it is required) is inserted into the MAC-e control SDU 1260. In the case of type 2, a buffer status report (BSR) 1275 for representing a buffer status (and padding bits if it is required) is inserted into the MAC-e control SDU 1260. Although not disclosed herein, more forms of types may be used. The system, to which the third exemplary implementation of an embodiment of the present invention is applied, has the same structure as the system shown in FIGS. 4A and 4B. The operations of the UE 402 and the Node B 437 will now be described with reference to FIGS. 4A and 4B. FIG. 13 is a flowchart illustrating the operation of the UE 402 according the third exemplary implementation of an embodiment of the present invention. In step 1305, the E-DCH transmission control unit 425 of the UE 402 triggers the transmission of MAC-e control information. In step 1310, the E-DCH transmission control unit 425 configures a MAC-e control SDU with the MAC-e control information, and transmits the MAC-e control SDU to the multiplexing and TSN setting unit 430. In step 1315, the multiplexing and TSN setting unit 430 sets the value of a DDI field of a MAC-e header part corresponding to the MAC-e control SDU as a special DDI value. In step 1320, the multiplexing and TSN setting unit 430 sets the value of an N field of a MAC-e header part corresponding to the MAC-e control SDU, as a value representing a kind of control information included in the MAC-e control SDU. The kinds of the MAC-e control SDUs and corresponding values of the N field have already been made known to the Node B and EUs. Although it is not shown, MAC-es PDUs including RLC PDUs created from the RLC entities 405 may be transmitted to the multiplexing and TSN setting unit 430. The multiplexing and TSN setting unit 430 sets a DDI field and an N field in each of header parts corresponding to the MAC-es PDUs, based on the size and/or the number of the RLC PDUs. In step 1325, the multiplexing and TSN setting unit 430 configures a MAC-e PDU by concatenating the MAC-e header including the MAC-e header parts, the MAC-es PDUs, and the MAC-e control SDU, and then transmits the MAC-e PDU to the Node B 437 through the HARQ entity 435 and logical layer. If there is no MAC-es PDU to be transmitted, a MAC-e PDU including only the MAC-e control SDU is transmitted. FIG. 14 is a flowchart illustrating the operation of the Node B 437 according to the third exemplary implementation of an embodiment of the present invention. In step 1405, the Node B 437 receives a MAC-e PDU including a MAC-e header and a MAC-e payload from the UE 402, and inputs the received MAC-e PDU to the demultiplexing unit 455. In step 1410, the demultiplexing unit 455 analyzes the MAC-e header of the MAC-e PDU, and divides the MAC-e payload included in the MAC-e PDU into MAC-es PDUs. The demultiplexing unit 455 checks DDI fields for each of the MAC-es PDUs. Step 1425 is performed if there is a DDI field having a special DDI value, and if not, then step 1420 is performed. When a DDI field is not identical to the special DDI value, a relevant MAC-es PDU is a general MAC-es PDU configured with TSN and RLC PDUs. Therefore, in step 1420, the MAC-es PDU is transmitted to the RNC 462. In contrast, when a DDI field is identical to the special DDI value, a relevant MAC-es PDU is a MAC-e control SDU including MAC-e control information. Therefore, in step 1425, the MAC-e control SDU is transmitted to the E-DCH reception control unit 445. In this case, the demultiplexing unit 455 reads the value of an N field corresponding to the MAC-e control SDU, and determines if the MAC-e control SDU includes effective MAC-e control information, such as power information or a buffer status report. If the MAC-e control SDU includes the effective MAC-e control information, this is notified to the E-DCH reception control unit 445. The E-DCH reception control unit 445 checks MAC-e control information included in the MAC-e control SDU, and performs appropriate operations, such as an operation for transmitting the control information to a scheduler. Some effects of the present invention, the exemplary effects obtained by the above-mentioned exemplary embodiments, will now be described. According to exemplary implementations of an the present invention, since the same header parts are used for packet data and MAC-e control information, the header structure of MAC-e PDUs may be formed with consistency, so that a UE and a Node B may simply transmit/receive MAC-e control information, such as power information and buffer status information, through a MAC-e PDU. In addition, since a supplementary header structure is not required for MAC-e control information, the MAC-e control information can be transmitted without increasing the size of the MAC-e header. While the present invention has been shown and described with reference to certain exemplary embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims and the equivalents thereof.
