Description

200536410 IX. Description of the invention: [Technical field to which the invention belongs] The field of the invention relates to a communication method in a wireless system, a client, a network element and a computer program. [Previous technology] In wireless systems that use packet switching connections, such as WCDMA (Wideband Coding Multiple Access) or UMTS (Universal Mobile Long-distance Communication System), encapsulation must have anti-noise functions, attenuation, and channel protection. Interference functions caused by coding, such as FEC (Transmission Error Correction Coding). Without protection operation, the receiving of the packet will be unsuccessful. This can be compensated by retransmission. When the transceiver receiving the packet requests to repeat the erroneous packet, a packet retransmission occurs. Implemented by ARQ (Automatic Repeat Request) agency. In a receiver using HARQ (hybrid ARQ), it is possible to combine error encapsulation and retransmission encapsulation to increase the probability of receiving the information properly. According to the OSI (Open Standard Interconnect) protocol model, HARQ connections can be included in a physical layer or a MAC (Medium Proximity Control) layer of a wireless system, both of which are located in the RLC (Wireless Link Control) layer. In this case, the encapsulation of the communication may consider the protocol data unit (PDU) of the MAC layer. In WDCMA, the uplink ARQ retransmission function is configured in the RLC layer. The RLC on the transmitter side (in the UE) adds an RLC PDU number to each RLC PDU (both in an informed mode (AM) and uninformed mode (UM)). The receiver-side RLC (in the RNC) then requests to retransmit the missing PDUs (in the AM), and based on these RLC PDUs, several PDUs are sorted in the original order. There are no other retransmission protocols specified in RLC. Its 200536410 means that RLC PDUs are received according to the order of retransmission (can exist, empty), that is, some PDUs are missed due to transmission errors, but no PDUs can be passed under RLC. Another PDU). The RLCPDUs retransmitted according to the basic configuration of the number of RLCPDUs are placed in the correct position. Because the corresponding RLC entities are in the UE and RNC, retransmission will cause delays. Some have been proposed for WCDMA uplink DCH One of them is to introduce a lower layer ARQ to provide a new retransmission agreement between the client and Node B. This ARQ can be defined as a new entity function or a new MAC layer function. In the latter, the new MAC The entity can be added to node B (where the connection is only due to the function of the substantial layer). We assume that a new Mac entity called MAC-e is added to node b to handle at least some ARQ related functions, such as generating ACK / NACK. ARQ has been proposed, the so-called HRAR (hybrid ARQ), in which early transmission of retransmission blocks (soft) combined with certain blocks is proposed. WCDMA, an enhanced dedicated wireless channel for wireless systems • Wuchi ) For HARQ. Due to retransmission, the RLC layer protocol 811 can be received in a different order than the transmission order. Therefore, for example, two consecutive transmission data units can be actually received in reverse order, and there are even other data during the period In HSDPA (Southern Speed Downlink Encapsulation Proximity), the reordering entity at the AC and hs layers under the MAC-d layer reorders the MAC_hs protocol data sheet ^ -MAC-hs protocol data unit is entering the MAC-d layer Wait in the queue until the step is lower than the MAC_hs agreement data sheet 6 200536410 of the transmission sequence number has been received or the time limit has been exceeded. According to the strengthening of the WCDMA system, connect the brain (dedicated = party: 'When sorting to be in the MAC- The MAC_e layer under the d layer can be performed in the > out-of-line network controller) or in node B. (There is no reordering ㈣, so if it is in the node order, when the reordering waits for a _ block, and When the poor data block is wiped out, Iub traffic increases sharply. There are many problems related to delivery (SH0) when uploading to Iub, such as the use of multiple nodes B. Here, SH0 is a number of nodes Received = ^ Connect the lean material block and report separately . Therefore, the reordering must be independent. The problem is that Node-B is waiting for a data block to pass the second to the RNC, but some other Node-B has been connected to the phase-block, and therefore the client does not Retransmit these data ... The poor data point B has been waiting for another data block, the first node ^ other arrives. Therefore, it must be received again in different nodes B.-term method is to avoid macro diversity The reordering is performed in the RNC. RSlty),, and Q are combined and the MAC_e paste under the recently proposed MAC-d is reordered into MAC-d (on the transmitter side) identifiable channels and different logical channels have Data block __d cut). Different priorities must be ordered, otherwise higher priority PDUs must wait to receive lower priority HXJ. Therefore, it is necessary to add certain priority information to each 200536410 MAC-e PDU (comparing the QID of the MAC-hs PDU), which increases the overhead. The reordering of data blocks requires each block to have a unique serial number. This lengthens the header and increases the sending of letters. In HSDPA (High-Speed Downlink Encapsulation Proximity) communication, several MAC-d PDUs can be multiplexed into one MAC-hs PDU, and a transmission sequence number (TSN) is associated with each MAC_hs PDU. A MAC-hs PDU is mapped to a transmission data block, and this data block is transmitted in the air interface.

give away. In an HS-DSCH (high-speed downlink and shared channel broadcast, each TTI (transmission interference) only transmits one transmission data block. Therefore, each TTI provides a TCN. Due to MAC-hs multiplexing, a MAC_hs PDU can contain several Different sizes of MAC-d PDUs, so the MAC-hs header is added to the TSN 'QID (sequence id), and the size and number of MAC-d PDUs are strengthened. This results in a more complicated MAC_hs header structure, and an extra header Data, especially at low data transfer rates. [Summary of the invention] The object of the present invention is to provide an improved communication party in a wireless system.

In addition, for the communication method invented by the computer, the number of computers (and several items can be reduced and the number of letters can be reduced. This is because you don't need the excellent = :, and it is transmitted in the same The chat in the period does not need to have a unique serial number. [Embodiment] Figure 1 shows the architecture of the wireless system of the present invention. The wireless system can be based on, for example, GSM (Global Communications for Mobile Communications), UMTS (Universal Mobile Phone) System) or WCDMA (Wideband Division Multiplexed Proximity Access). The core network can correspond to the final structure of the GSM and GPRS system 200536410 (GPRS envelops the wireless system). The GSM network components are connected by circuit switching Configuration, and the GPRS network element is used to configure the packet switching link, but some network elements are shared by both systems. + A mobile service switching center (MSC) 100 performs circuit switching signaling in the wireless system. A serving GPRS support point (SGSN) can also perform packet switching and transmission. The MSC 100 controls the traffic in the wireless system. The core network has a gate unit 102, which is used for the nuclear and radio circuits Gated Mobile Service Switching Center (GSMC) with circuit switching link between external and external networks, such as a public mobile network (plmn) or a shared switched telephone network (pSTN). Gated GPRS Support Point (GGSN) 10'3 Add a packet switching link between the core network and an external network (such as the Internet). 'The MSC 100 and SGSN are connected to a wireless proximity network (RAN) 104. The network operation includes at least one Wireless network controller Control at least one node B 108. The wireless network controller 106 can also be referred to as a base station controller, and node B can be referred to as a base station. One use • Client U0 and at least one node B in the air interface The client 110 can use the GPRS method to communicate with Node B 108. The data in the envelope includes the address and control data (except the original communication data). Multiple data can use the same at the same time Transmission channel. The encapsulation switching method is suitable for data transmission, so that data to be transmitted is generated in the cluster message. In this site, there is no need to allocate a data link during the entire transmission, but it is only needed when transmitting the encapsulation. distribution. This considerably reduces costs and saves capacity during the establishment and use of the network. You can consider other components that include the steps of the scale system in the wireless network infrastructure of 13 200536410, but usually the client is mobile. In the case of a client, the user terminal 110 transmits a signal 200, such as encapsulation, to a node B 108 inch node ^ B 108 can receive the signal correctly or the reception fails. The node B1 or the radio network controller 106 calculates a checksum (CRC cyclic redundancy check) and compares the checksum contained in the envelope with the leaf leaf checksum. If the two checksums agree, φ is suitable for receiving the envelope. On the other hand, if the check sum does not match, the reception fails. • Figure 9 shows the retransmission of pDu and its effects. In this example, the user knows that the underlying structure of the network evenly buffers memory to store PDUs. If necessary, the PDU 200 is successfully transmitted from the client to the first ττι (transmission time interval) network infrastructure, and is notified from the network infrastructure by an ACK (information) signal. The second PDU 202 is transmitted, and if the transmission fails', the network infrastructure transmits a NACK (Notify) signal 216. The third PDU 204 was successfully transmitted, and an ACK signal 218 was used from the network infrastructure to inform the message. The second PDU 202 is retransmitted, but the retransmission fails, and the network infrastructure transmits a NACK signal 220. The fourth PDU 206 is successfully received, and a transmission signal 222 is used to inform the message. The second PDU 202 was retransmitted at the second time, and the transmission was successful this time. The network infrastructure transmits an ACK signal 224. The pdu is continuously transmitted in a manner similar to the fourth PDU 208, and so on. Transmission causes PDUs to be mixed, and in this example, the order becomes 1, 3, 4, 2, and this order must be configured appropriately again. 14 200536410 Figure 3 shows the protocol architecture of this element, for example in a υMτ§ or WCDMA wireless system. Using the OSI protocol mode, the client can include a radio link control (RLC) entity 3022, a transport network (TNL) entity 3024, and a signal backbone protocol entity (Fp) 3026. Node B may include a MAC-e entity 3020, a physical entity 3022, a transport network (TNL) entity 3024, and a certain frame protocol body (FP) 3026.

The radio network controller 106 may include an RLC entity 3040, a MAC-d entity 3042, a MAC-e entity 3044, a data hub entity (FP) 3046, and a TNL entity 3048. The RNC may also include an entity 3048, which is located between the RLC entity 3040 and the MAC_d entity 3042. This entity can be regarded as an operating unit established by an electronic circuit with a processor and a memory. This is actually achieved using appropriate calculation procedures. The RLC entities 3000 and 3040 in the RLC layer of the OSI mode are protocols for controlling signal transmission on the air interface of the encapsulation switching link of the UMTS wireless system. Therefore, important features of the RLC layer such as flow rate control and error recovery. The MAC-d layer is an asymmetric layer. The MAC-d entities 3002 and 3042 in the user terminal u0 and RNC 106 are not the same to some extent. However, the MAC-d entity 3002 and 3042 protocols perform actions such as multiplexing between logical channels and transmission power. This is because the air interface has logical channels mapped to the transmission channels, but it can also map to the physical channels. The logical channels include the following link (DL) broadcast control channel (BCCH), one (DL) call control channel (PCCH),-uplink / downlink 15 200536410 control (Dcch) dedicated to UL (DL), _ (uL / DL) shared control channel (CCCH), (UL / DL) dedicated traffic channel (dtcH) and one-way shared traffic channel (CTCH). The MAC-e layer is used to handle functions such as enhanced uplink DCH. In the MAC-e entity on the user side, this function can include the following items. Each user terminal has a HARQ entity for handling functions related to the hybrid arq protocol. Every TTI is a HARQ procedure which usually must be processed. A MAC-e header can be added to each MAC-e entity PDU (such as an E-DCH transmission block). The header can contain a series of numbers for reordering purposes. In the MAC-e entity of the network's underlying structure, this function can include the following functions. Perform communication schedule of E-DCH transmission between clients. Corresponding to a transmitted TTI, the MAC-e generates an ACK / NACK signal for HARQ operation. The received MAC_e PDUs are reordered based on the received MAC-e sequence number. Remove the MAC-e header to get the MAC-ePDU and send it to the upper layer of MAC-d. On the substantial layer, the signaling action between the client and the Node B is performed. The substantial entities 3006 and 3020 can also perform HARQ operations. The TNL entities 3024, 3048 in the substantial layer execute the signaling between the nodes B8 and RNC108. The data hub agreement entities 3026, 3046 process the headers of the physical channel, such as the number of linked data frames, and according to this method, the combination such as macro diversity can be performed. If reordering of data units is performed on Node B. In this case, these entities may not be present in the RNC. 16 200536410 ^ The entities 3008, 3028, and 3048 between the RLC layer and the MAC_d layer are related to a solution ^ where the appropriate sequence is used according to the transmitted serial number 'in the RCL entity 3000 and the entities 3008, 3028, 3048 use f The end U10 'reorders the PDUs in the appropriate order in the MAC_d entity 3002 which is related to the PDU with the transmission sequence number and the node B108, or the RNC 106 in the RCL 3040, the entity 3048, or the MAC-d entity 3042. Figure 4 shows the MAC-d entity at the user end under the RLC entity 3000. The transmission channel type switching entity 400 can switch the mapping of the specified logical channel between the shared and used channels, because this is related to wireless resources. The radio resource control terminal controls the switching of the channel. In serial number 402, the serial number is related to the underlying structure of the network = PDU ^. The method is to add a continuous number = to a header of a continuous PDU in a predetermined window. The maximum value of the serial number defines the window% length. For now, please refer to the figure below to keep the memory numbers using < The sequence number indicates the order in which PDUs are transmitted. No • There is a correlation between PDUs and different serial numbers. It is possible to establish correlations between data units and a serial number, and to establish a correlation between the special period and consecutive serial numbers. The parallel, C / T entity 404 can multiplex a dedicated logical channel to a transmission channel. The C / T identification of each logical channel is added to the header of different logical channels, and several logical channels are multiplexed into a MAC_d shell stream or transmission channel. The C / T usually identifies the 4-bit channel number used in the header of the PDU. The TFC (Transport Format Combination) entity 406 performs the selection of the combination of the transmission format and the transmission format under the control of the radio resource controller. The scrambled entity 408 transmits pattern data that can be scrambled. Instead of using the position of FIG. 4, the numbered entity 402 may be located in the MAC-d entity 3002 above the C / T entity 404 or in the RLC entity 402 as the last operating entity according to this embodiment. The numbering entity 402 can number PDUs in logical channels, that is, each channel has a different serial number. According to another embodiment, the numbering entity 402 may be a separate entity of its own. The numbering entity 402 must reside between the RLC entity 3000 and the MAC-d entity 3002. Figure 5 shows the MAC-d entity 3042 under the RLC entity 3040 of the RNC. If more than one dedicated channel is multiplexed to the user's transmission channel, according to the C / T in the PDU header, a C / T entity 500 Demultiplex the transmitted channel into several dedicated logical channels, and remove the C / T header in this entity. The sorting entity 502 sorts the received PDUs into a discrete entity or a part of the RLC entity 3002 or the MAC_d entity 3002 according to the serial number given by the numbering entity 402 of the client. Because each logical frequency has only one priority, such as in a WCDMA or UMTS wireless system, this priority is not transmitted, which can save space in the heading & header of the transmission. The reordering sequence can be used for each logical power, which has the advantage of high priority]? £) 1; low priority lion PDUs that wait for offline delay when receiving and sending. The reordering sequence can be completed by a memory 18 200536410 body. A window or at least one timing mechanism (similar to the HSDP mechanism) can be used to limit the PDU waiting time and process expired PDUs. The ordering entity 502 may remove the sequence number and transmit the PDUs to the RLC layer in an appropriate order. -The password can be removed in the decryption body 504. The transmission channel type switching entity 506 sends a response operation to the user's transmission channel type switching entity 400.

If reordering of PDUs is performed in the RNC, a giant set-of-sets combination (MDC) can be used. In MDC, the signaling wheat (PDU) from different node Bs can be combined with the same node B based on the number of connected data hubs in the RNC. This efficiency can be performed using, for example, a selective combination method. This advantage is, for example, fixed Iub traffic, MD efficiency without delay, and out-of-synchronization of reordering sequences. Figure 6 shows a block diagram of ordering in MAC-d entities. In this example, there are several E_DCH transmission blocks in each client and in each TTI. Because the MAC-e entity 3044 maps each E_DCH transmission channel 60 to a MAC-d data stream 602, the MAC_e entity 3044 is not needed. The dotted line shows an example using MAC_e multiplexing. Otherwise, each frequency can be mapped into a MAC_d data stream. The DCH channel and the MAC-e stream are input into the MAC-d demultiplexer 606 (corresponding to the C / T entity 500) ′ The data stream is demultiplexed and transmitted to the logical channel. The PDUs of each logical channel 608 can be arranged in the sorting data in an appropriate order (corresponding to the sorting entity 502). Then sort & PDUs are rounded into RLC entity 3_. This has different error protections for different logics. Rather than reside in the MAC-d entity 3042, the sorting entity 502 may be a separate entity from the MAC-d entity 3042 and the RLC entity 3042. In addition, the ranking entity 502 may also be located in the RLC entity 3040. Because after the logical channel is demultiplexed in RNC, reordering can be performed, that is, as an operation before RLC, or as one of the first operations in RLC, it is possible to use RLC memory for reordering. Also _ it is possible to perform reordering in the same processing, as in the RLC entity. Reordering may also be performed in Node B 108. Then the function is as described above, but the MAC-d entity 3020 may replace the MAC_d entity 3042. The MAC-e entity 3020 may replace the MAC-e entity 3044, and the entity 3028 on the MAC-d entity 3020 may replace the entity 3048. The entity 3028 can be considered as part of the RLC entity in node b. -Figure 7 shows the non-delivery lean stream between the RLC layer 700 and the substantial layer 704. The RLC layer on the user side forms the RLC data units 706 to 708 'which are the data units received from the higher layers. The [V-AC-d through body 702 of the client numbers 710 to 712 is connected to the MAC_d data units 714 to 7/6. Moreover, the C / T identification numbers 718 to 72 can also be linked to different data units of the editing channel (if several logical channels are multiplexed into one channel) 'and form data blocks 722 to 724. After the data blocks are transmitted to the acoustic and shell layers, the 'CRC total number pairs enter each data block 722 to 724. f After the material block 722 in the physical layer 704 of the underlying structure of the network (usually node B), compare the starting CRC total collation with the calculated 20 200536410 CRC total branch pair. In the MAC-d layer 702 of the network infrastructure (usually the RNC), the MAC_d entity data units 714 to 716 of each logical channel are configured in an appropriate order according to τ§N numbers 71 to 712. Demultiplexing logic frequency based on possible C / T identification numbers 718 to 72. Thereafter, the lean list t1 is transmitted to the RCl layer 700 and higher. FIG. 8 shows the opaque data flow between the RLC layer 800 and the layer 806 via the MAC-e layer 804. The RLC layer on the client side forms the RLC data units 808 to 810, from the data units received from the higher layers. In the client's MAC-d layer 802, serial numbers 812 to 814 are connected to and MAC-d data units 816 to 818. Furthermore, the C / T identification numbers 820 to 822 are connected to the MAC_d data units of different logical channels. At this time, it is necessary to multiplex multiple logical channels to a transmission channel and form a data block. After this 'transmit the data blocks 824 to 826 to the MAC-e layer 804, this layer can connect the MAC-e header 828 to the data blocks 824 to 826 transmitted in the TTI' and combine the data blocks 824 to 826 in the transmission block 83〇. By applying this method, the previous data can be reduced. In the material layer 806, the CRc core φ pairs the aggregated and transmitted data blocks 830. In the physical layer 806 of the network's underlying structure (usually Node B), after receiving the transmitted data block, the relevant CRC checksum 832 is compared with a different CRc checksum to check the reception quality. In MAC_e, the data block 830 is divided into data blocks 824 to 826 on 04 ^ '. However, the MAC-e header is removed to form the table master units 824 to 826 for the MAC_d layer 802. In the MAC-d layer 802 of the network's underlying structure (usually CNC), 21 200536410 MAC-d entity data units 816 to 818 of each logical channel are arranged in an appropriate order, based on TSN numbers 812 to 814. Demultiplexing logical channels based on possible C / T identification numbers 820 to 822. Thereafter, the data unit is transferred to the RLC layer 800 or higher. Each logical channel is appropriately numbered separately. When using the number of logical channels (C / T column in the MAC-d header) to demultiplex a logical channel to a transmission channel, separate the logical channel. Otherwise, logical channels are separated based on the transmission channel used. The priority in the WCDMA wireless system is configured so that each logical channel has a given priority. If the sequence is numbered separately for each logical channel for the purpose of reordering, it is not necessary to transmit the priority, so the head data of the transmission in the frequency band is saved. If MAC-e multiplexing is not used, no MAC-e headers need to be added to the MAC_d entity PDU (instructions such as the size and number of PDUs). Then the MAC-d PDU and TSN number with (selected) C / T block can be simply transmitted to the substantial layer for channel coding and transmission. FIG. 9 shows the flow of transmitting two logical channels to one transmission channel. As described above, the serial numbers 904 to 906 that can be applied to the first logical channel 908 number the MAC-d PDUs 900 to 902, respectively. For example, the serial number of the first PDU 900 is TSN = 1, and the serial number of the second PDU is TSN-2. It is still the same for the second logical channel 914, where the PDU 910 is related to the serial number 912. The logical channels are separated from each other by C / T identification numbers 916 to 918. The transmission sequence numbers 800 to 802 can be 8 bits, because multiple PDUs can be included in a TTI. That is, if each MAC-d PDU has been given a proprietary MAC-e header, it is less than the number required by the MAC-e number. 22 200536410 Requirement 'This is because no identification code is needed. FIG. 10A shows a method of shortening the MAC-d transmission sequence length. For example, all MAC-d entity PDUs 1002 of the logical channel 1006 transmitted within TTI 1010 using the same serial number 1000 may be used. In different logical channels 1006 and 1008, logical serial numbers of 1000 and 1012 are used, and logical channels are separated by C / T identification codes 1014 to 1016 respectively. In consecutive TTI 1010, 1018, consecutive serial numbers 101 to g 1012, 1020 to 1024 are used. Fig. 10B shows the possibility of compressing the header when similar to Fig. 10a. In the logical channel, the header of the MAC-d PDU is combined to reduce the MAC header data to a single MAC-e header, or some other header of the (direct) MAC entity is transmitted under the MAC_d entity. Generally, when the problem is that the PDUs are related to a same logical channel and have a common transmission sequence number, adding a PDU header of the MAC entity can be used in a single header of two MAC entities, which resides in the first MAC entity. under. Therefore, the information in the PDU transmission sequence of the first MAC entity can be linked to the header of the first mac entity. For example, the client PDUs 1002 (SDU1 and SDU2) may have the same common header 1050, which is related to a logical channel and a transmission sequence. In a similar manner, PDU 1004 (SDU3 and SDU4) may have a common header 1052, and PDU 1005 (SDU5 and SDU6) may have a common header 1054.

Because the MAOd entity selects the link of the transmission format, the MAC_d entity knows to transmit the MAC_d PDU within the same TTI. Each TTI 23 200536410 only needs a transmission sequence number. This is because the MAC-dPDUs in a TTI cannot be out of sequence, and only the PDUs of different TTIs need to be reordered. In this case, a 4 to 5 bit transmission sequence number is sufficient (4 bits in i0msTTI is sufficient, 5 bits are required in 2msTTI). Figure 11 illustrates the transmission in the E-DCH channel when MAC-d layer multiplexing is not used, that is, PDUs 1102, 1104, 1106, 1122, 1132, 1134, 1143, 1144, 1152 do not include C / T blocks. This is because the logical channel separation operation is not performed. In this example, please refer to the figure now. All MAC-d PDUs transmitted within a TTI use a determined sequence number, and consecutive sequence numbers are used in consecutive TTIs. Therefore, in the first ττι 1100, PDUs 1102 to 1106 are transmitted and each has a serial number TSN = 2. In the second TTI 1120, the PDU 1122 is transmitted and the sequence number may be TSN = 2. In the third TTI 1130, PDUs 1132, 1134 are transmitted and both may have a sequence number TSN = 3. In the four TTIs 1140, PDUs 1142 and 1144 are transmitted, and both have the same sequence number TSN = 4. In the fifth TTI 1150, the PDU 1152 is transmitted, and its serial number can be TSN = 5, and the rest can be analogized. Figure 12 illustrates the signal transmission in the E-DCH channel when MAC-d layer multiplexing is used, that is, PDUs 1202 to 1206, 1222, 1232, 1234, 1242, 1244, 1252 contain C / T blocks. Separation of logical channels. Moreover, in this example, the same sequence number is used for all MAC-d PDUs of the same logical channel transmitted within a TTI, and consecutive sequence numbers are used in consecutive TTIs. Therefore, in the first TTI 1200, PDUs 1202 to 1206 are transmitted, and PDUs 1202 and 1204 belong to the same 24 200536410 fun channel (C / T = 1), and their serial numbers may be the same (TSN = 1). PDU 1106 belongs to different logical channels, where C / T number C / T = 2, but the serial number can also be TSN-α. In the second TTI, the PDU 1202 is transmitted, and its serial number may be TSN = 2, and the number of logical channels C / T = 1. In the third TTI 1230, the logical channel number C / T II of 'Transmit PDU 1232' 1234 PDU 1232 and the serial number TSN = 3 are transmitted in the second TTI based on the logical channel number (in TTI 1220, there is no Transmission of PDUs with logical channel number C / T = 2). In the fourth TTI 1240, the number of logical channels transmitting pdu 1242, 1244 ′ c / T = 1, and the serial number TSN C / T = 2, and the serial number TSN = 3, and the rest can be deduced by analogy. FIG. 13 illustrates a flowchart and a computer program according to an embodiment of the present invention. In step 1300, the data unit of the logical channel is related to the serial number in the transmitting client. The data unit of each logical channel is related to the serial number in the physical proximity of the medium. This is performed in a wireless link control entity or an entity between the wireless logic control entity and the medium proximity control d entity. FIG. 14 illustrates a flowchart of an embodiment of the present invention. In step 1400, the data unit of at least one logical channel related to the serial number of the client is received in the network infrastructure. In step 1402, data elements of each logical channel are configured in a network element of a network underlying structure. FIG. 15 illustrates a flowchart and a computer program according to an embodiment of the present invention. In the whole 1500, each data unit of a logical channel in a transmission period is associated with a second serial number. In step 1502, the information 7 ^ in the continuous transmission period is related to the continuous sequence number in the transmitting user terminal. 25 200536410 FIG. 16 is a flowchart illustrating an embodiment of a computer program according to the present invention.
