The disclosure shows only the apparatus configuration and / or processing steps that are closely related to the proposed solution, and this disclosure is almost identical to the present disclosure. Please note that other unrelated details have been omitted.

[0013] The embodiments described herein will be explained in detail below with reference to the drawings.

[0014] Figure 1 shows a functional module of an electronic device 100 for wireless communication according to one embodiment of the present disclosure. A block diagram is shown, and as shown in Figure 1, the electronic device 100 is connected to the electronic device 100. Repeated transmissions to the base station providing the service, including transmission blocks from the 1st to the repKth. When performing this, a predetermined continuous time domain position for repeated transmission configured by the base station If the first n-1 consecutive time-domain positions are unavailable, then the nth time-domain position When it is detected that it is available, starting from the nth time domain position, the 1st or Repeat transmission of at least some of the transmission blocks up to the repKth transmission block A transmission unit 102 which may be configured to transmit, and a first redundant version received from the base station Based on the pattern, determine the redundant version number corresponding to each transmitted transmission block. It includes a determination unit 104 which can be configured to receive a first from the base station, and repK includes a determination unit 104 which can be configured to receive a first from the base station. This is the number of repeated transmissions, where n is an integer between 1 and repK.

[0015] The transmission unit 102 and the determination unit 104 may be implemented by one or more processing circuits. The processing circuit can be implemented, for example, as a chip.

[0016] The electronic device 100 is installed, for example, on the user equipment (UE) side, or communicates with the UE. They may be connected as possible. Here, the electronic device 100 may be implemented at the chip level. It may also be implemented at the device level. For example, electronic device 100 is the user device itself It may also operate as such, and externally, for example, memory, transceiver (not shown), etc. The unit may further include devices. Memory is used to enable user devices to perform various functions. Used to store programs that need to be executed and related data information. A transceiver is used to communicate between different devices (e.g., base stations, other user equipment, etc.). To support communication, it may include one or more communication interfaces, but here Therefore, the specific form in which the transceiver will be implemented is not limited.

[0017] A base station can be, for example, a gNB (Global Network Module).

[0018] For example, the above predetermined continuous time domain location is a mile pre-assigned by the base station. A sense (configured grant, CG) is a time-domain position. For example, The number of specified continuous time domain positions is greater than or equal to repK. The CG time domain positions are CG ri The time domain period to which a given continuous time domain position belongs, which can be called the source, is called the CG period. obtain.

[0019] For example, the transmission unit 102 uses a scheduling-free method on an unlicensed band. This configuration enables repeated transmission of transmission blocks (TB) (also known as redundant transmission). This can be done. For example, the transmission unit 102 performs a Hybrid Automatic Retransmission Request (HARQ) The process can be configured to repeatedly transmit transmission blocks.

[0020] Communications on unlicensed bands employ a fair competition mechanism for channel occupancy. The UE obtains configuration information about the resources available within the CG cycle from the base station. It performs channel idle detection and attempts to occupy pre-configured resources for data transmission. However, at a pre-configured time-domain location where the channel can be accessed, When the UE detects that the base station is busy, it will configure the repetitive transmission configured by the base station. The transmission block cannot be sent at the above time-domain position. Channel detection is, for example, For example, LBT (Listen Before Talk). At least some of the time-domain locations pre-assigned by the local station will be affected by the failure of LBT. This can sometimes prevent the transmission of a transmission block. For example, LBT The failure of the base station resulted in a predetermined continuous time domain position for repeated transmission. The first n-1 continuous time domain positions of the positions become unavailable, and therefore the first Transmission of the transmission block cannot be performed at n-1 consecutive time domain positions.

[0021] The transmission unit 102 utilizes the nth time domain position among the predetermined continuous time domain positions described above. If possible, start from the nth time domain position and proceed from the 1st to the r Repeat transmission of at least some of the transmission blocks up to epK To do so. For example, the transmission unit 102 has at least the following continuous time positions from the nth time domain position: It also performs repeated transmission of some transmission blocks.

[0022] For example, the first redundant version pattern is the redundant version sequence {0,2,3, It can be one of {1}, {0,3,0,3}, and {0,0,0,0}.

[0023] The determination unit 104 determines each transmitted transmission block based on the first redundant version pattern. The corresponding redundant version number can be determined.

[0024] The electronic device 100 according to the embodiment of this disclosure is connected to a channel pre-configured by the base station. If the channel is found to be busy at certain time-domain locations during access, it becomes available. Only after a valid time-domain position is detected, the transmission block is repeatedly transmitted and transmitted. The redundant version number of the transmission block can be determined, and the base station, after receiving the redundant transmission, Combinatorial decoding can be performed effectively.

[0025] For example, the determination unit 104 determines the first redundant version pattern (mod(n-1 The 4th (+1)th data point is used as the redundant version number corresponding to the nth transmission block. It can be configured in such a way that mod() is a modulo operation. In this way, each transmission block The corresponding redundant version number can be easily and simply determined.

[0026] repK=4, and the first redundant version pattern is redundant version sequence {0, Taking {2,3,1} as an example, when n=1, it corresponds to the first transmission block TB0. The redundant version number is the first data in the first redundant version pattern. Therefore, its redundant version number is 0, and in the case of n=2, the second transmission block The redundant version number corresponding to TB1 is the second in the first redundant version pattern. This is the data for the eye, and therefore its redundant version number is 2, and if n=3, then it is the 3rd. The redundant version number corresponding to the transmission block TB2 is the first redundant version pattern. This is the third data point in n, meaning its redundant version number is 3, and n=4 In this case, the redundant version number corresponding to the fourth transmission block TB3 is the same as the first redundant version number. It is the fourth data in the version pattern, i.e., its redundant version number is 1 That is the case.

[0027] repK=4, and the first redundant version pattern is redundant version sequence {0, Using {3,0,3} as an example, when n=1, it corresponds to the first transmission block TB0. The redundant version number is the first data in the first redundant version pattern. Therefore, its redundant version number is 0, and in the case of n=2, the second transmission block The redundant version number corresponding to TB1 is the second in the first redundant version pattern. This is the data for the eye, and therefore its redundant version number is 3, and if n=3, then it is the 3rd. The redundant version number corresponding to the transmission block TB2 is the first redundant version pattern. This is the third data point in n, meaning its redundant version number is 0, and n=4 In this case, the redundant version number corresponding to the fourth transmission block TB3 is the same as the first redundant version number. It is the fourth data in the version pattern, i.e., its redundant version number is 3 That is the case.

[0028] repK=4, and the first redundant version pattern is redundant version sequence {0, Taking {0,0,0} as an example, when n=1, it corresponds to the first transmission block TB0. The redundant version number is the first data in the first redundant version pattern. Therefore, its redundant version number is 0, and in the case of n=2, the second transmission block The redundant version number corresponding to TB1 is the second in the first redundant version pattern. This is the data for the eye, meaning its redundant version number is 0, and if n=3, it is the 3rd. The redundant version number corresponding to the transmission block TB2 is the first redundant version pattern. This is the third data point in n, meaning its redundant version number is 0, and n=4 In this case, the redundant version number corresponding to the fourth transmission block TB3 is the same as the first redundant version number. The fourth data in the version pattern, i.e., its redundant version number, is 0 That is the case.

[0029] For example, the transmission unit 102 is the first n-1 consecutive time within a predetermined continuous time domain position The first n-1 transmissions from the 1st to the repKth transmission at the inter-region location The transmission of the block is abandoned, and the above detected as available within a predetermined continuous time domain location. Starting from the nth time-domain position, transmit at least the nth transmission block. It can be configured in this way.

[0030] For example, the transmission unit 102 has access to channels pre-configured by the base station. At the first n-1 consecutive time domain positions among the predetermined consecutive time domain positions, the channel is visible. - If it is discovered that the first n-1 consecutive time domain positions are The transmission block is abandoned. Also, the transmission unit 102 detects the channel within the CG period. Performed continuously, the nth time domain of predetermined continuous time domain positions for repeated transmission If the channel is successfully detected as idle at the position, then at the nth time-domain position Send the nth transmission block.

[0031] The base station pre-allocates multiple time-domain periods for repeated transmission to the electronic device 100. These periods correspond to the predetermined continuous time domain positions for the repeated transmission described above. It is called a time-domain period of the same type as the time-domain period. In the following figure, pre-allocated Each of the time-domain periods for repeated transmission is defined as CG-period_0 and . The time domain period that is not allocated to the repeated transmission of the electronic device 100 is the same as the repeated transmission. A time domain of a different type from the time domain period to which a predetermined continuous time domain position for return transmission belongs. The time-domain period, which is not assigned to the repetitive transmission of electronic equipment 100, is called the time-domain period. It is marked as G-period_1.

[0032] In Figures 2 to 8 described below, repK=4, and the first redundant version pattern The example given is that the sequence is a redundant version sequence {0,2,3,1}, and the diagram shows The time-domain position marked with the first "X" in the first CG-period_0 is , a predetermined continuous time domain location that can be used for repeated transmission preconfigured by the base station This represents the first time-domain position, and the following are the consecutive time-domain positions after the first time-domain position. The positions are the second time domain position and the third time domain position among the predetermined continuous time domain positions. This is referred to as the domain position, the fourth time-domain position, etc.

[0033] Figure 2 shows the transmitted transmission block according to the embodiment of this disclosure, and the corresponding transmission block. This shows a schematic diagram of redundant version numbers.

[0034] In Figure 2, the transmission unit 102 is used for repetitive transmission pre-configured by the base station. The channel is busy at the first of the possible consecutive time-domain locations. Upon discovering this, the transmission of the first transmission block TB0 at the first time domain location is It is abandoned. And the transmission unit 102 is a predetermined continuous time domain position for repeated transmission. If the channel is successfully detected as idle at the second time-domain position, 2 The second transmission block TB1 is transmitted at the second time domain position. The redundant version number RV corresponding to transmission block TB1 is the first redundant version pattern This is the second data point in the sequence, meaning RV=2.

[0035] Figure 3 shows the transmitted transmission block according to the embodiment of this disclosure, and the corresponding transmission block. Another schematic diagram of redundant version numbers is shown.

[0036] Figure 3 shows that the transmission unit 102 can be used for repeated transmission, which is pre-configured by the base station. The first three (i.e., the 1st to 3rd) time domain positions among the predetermined continuous time domain positions If it is discovered that the channel is busy, then the first of the first three time-domain positions ~The transmission of the third transmission block TB0-TB2 is abandoned. Then, the transmission unit 102 repeats At the fourth time domain position among the predetermined continuous time domain positions for return transmission, the channel If it is successfully detected that it is idle, the fourth transmission block at the fourth time domain position Send lock TB3. As described above, redundant blocks corresponding to the fourth transmission block TB3. The version number is the fourth data point in the first redundant version pattern, i.e., RV = 1.

[0037] For example, the transmission unit 102 is the nth available time domain position at a predetermined continuous time domain position. After sequentially transmitting transmission blocks from the first to the repKth position, a predetermined continuous time domain position If it is detected that there are i additional available time domain positions within the time domain period to which it belongs, In addition, using i additional available time-domain positions, the first n-1 transmissions that were abandoned The first i transmission blocks of the transmission block are transmitted sequentially, and the same time domain period is From the 1st to the repKth available time-domain position within the next time-domain period of the same type The transmission blocks that were not transmitted within the time domain period are transmitted sequentially. Alternatively, the transmission of a transmission block that has not been sent may be abandoned, i is 0 or greater and It is less than or equal to n-1.

[0038] After the transmission unit 102 transmits the nth transmission block at the nth time domain position, Electronic device 100 continues to occupy the channel, thereby preventing transmission after the nth transmission block. The blocks are transmitted sequentially. After transmitting the repK transmission block, the time domain period... If there are additional available time domain positions within the period, the transmission unit 102 will not detect channel detection failures. The transmission block that was not sent due to failure is shifted after the repK transmission block. Send it.

[0039] For example, all transmission blocks that were not sent due to channel detection failure are as described above. If transmission is possible at an additional available time domain location, the transmission unit 102 will not attempt to transmit at the channel detection location. All transmission blocks that were not transmitted due to failure are transmitted within the relevant time domain period.

[0040] As shown in Figure 2, the transmission unit 102 is second within the time-domain period CG-perood_0 After transmitting transmission block TB1, continue with TB2-TB3 (RV of TB2-TB3) These are 3 and 1 respectively) and send. After sending TB1-TB3, the time There are additional available time domain positions within the domain period, and these additional available time domains The position is sufficient to send the TB0 that was not sent due to the channel detection failure mentioned above. Therefore, the transmission unit 102 shifts TB0 after TB3 and keeps TB within the time domain period. Send 0.

[0041] For example, the above additional available time-domain locations are transmitted due to channel detection failure. If it is not enough to transmit all of the transmission blocks that have not been transmitted, the transmission unit 102 will A portion of the transmission block that was not transmitted due to channel detection failure is included within the relevant time domain period. Transmit and the available time domain positions within the next time domain period of the same type as the current time domain period. And the remaining transmission blocks that were not sent due to channel detection failure By sending the block, the transmission block from 1 to repK is completely transmitted. It can be guaranteed that this will be the case. The transmission unit 102 is a time of a different type than the time domain period. Within the inter-period, the transmission block transmitted by the electronic device 100 must not be transmitted. Please take note of this.

[0042] As shown in Figure 3, the transmission unit 102 transmits TB3 within the time domain period CG-perood_0. After transmission, there are additional available time domain positions within that time domain period, but The available time domain position of TB0-TB was not transmitted due to channel detection failure. Since it is not enough to transmit 2, the transmission unit 102 transmits TB0-TB1 (RV each The TB3 (which is 0 and 2) is shifted after the TB3 and transmitted within the time domain period, and the TB2 ( RV (which is 3) is transmitted within the next time-domain period CG-perood_0.

[0043] Figure 4 shows the transmitted transmission block according to the embodiment of this disclosure, and the corresponding transmission block. Another schematic diagram of redundant version numbers is shown. The difference between Figure 4 and Figure 3 is that in Figure 3, the following Regarding TB2 transmitted within the time domain period CG-perood_0, CG-pero od_0 is a different type of CG-perood_1 (i.e., repeated by electronic device 100) Figure 4 clearly shows that the TB2 cannot be transmitted within the time domain period (which is not allocated to transmission). This is what is being adjusted. For example, the transmission unit 102 may abandon the transmission of the TB2. can.

[0044] As can be seen from the above explanation, the repeated transmission explained with reference to Figures 2 to 4 above During transmission, the transmission unit 102 detects transmission blocks that were not transmitted due to channel detection failure. The cycle shifts.

[0045] For example, the transmission unit 102 detects an available location within a predetermined continuous time domain. Starting from the nth time-domain position mentioned above, transmit at least one transmission block. It can be configured in this way.

[0046] For example, the transmission unit 102 has access to channels pre-configured by the base station. At the first n-1 consecutive time domain positions among the predetermined consecutive time domain positions, the channel is visible. When it is discovered that this is the case, then from the first of the first n-1 continuous time domain positions, re The transmission of the first n-1 transmission blocks out of the pK transmission blocks is abandoned. Then, the transmission unit 102 continuously performs channel detection within the CG cycle and repeats the transmission. The channel is idle at the nth time domain position out of a given set of continuous time domain positions. If successful detection occurs, the first transmission block is sent at the nth time domain position. .

[0047] Figure 5 shows the transmitted transmission block according to the embodiment of this disclosure, and the corresponding transmission block. Another schematic diagram of redundant version numbers is shown.

[0048] In Figure 5, the transmission unit 102 is pre-configured by the base station for repeated transmission. The channel is busy at the first of the predetermined continuous time domain positions that can be used. Upon discovering this, the first transmission block TB0 at the first time domain position (that The transmission of RV=0) is abandoned. Then, the transmission unit 102 performs a predetermined sequence for repeated transmission. The channel is successfully idle at the second time-domain position among the consecutive time-domain positions. If detected, the first transmission block that was abandoned at the second time domain position (its RV) Send =0).

[0049] Figure 6 shows the transmitted transmission block according to the embodiment of this disclosure, and the corresponding transmission block. Another schematic diagram of redundant version numbers is shown.

[0050] In Figure 6, the transmission unit 102 is configured by the base station for repeated transmission. Channeling is performed at the first to third time domain positions out of the predetermined continuous time domain positions that can be used. When it is discovered that the first of the three time domain positions is busy, The transmission block TB0 (with RV=0) is abandoned. The transmission unit 102 repeatedly The channel idles at the fourth time domain position out of a predetermined continuous time domain position for transmission. If it is successfully detected that it is a , the abandoned first transmission is placed at the fourth time domain position. Send the send block (its RV=0).

[0051] For example, after transmitting the first transmission block, the transmission unit 102 transmits a predetermined continuous time portion There are available time-domain locations of repK-1 or higher within the time-domain period to which the region location belongs. If detected, the transmission blocks from the 2nd to the repKth within that time domain period. It can be configured to transmit sequentially.

[0052] After the transmission unit 102 transmits the first transmission block at the nth time domain position, Electronic device 100 continues to occupy the channel, thereby preventing transmission after the first transmission block. Send the blocks sequentially.

[0053] For example, as shown in Figure 5, after transmitting the first transmission block, repeated transmission There are three or fewer predetermined continuous time domain positions within the time domain period CG-perood_0 to which a given continuous time domain position belongs. Because there is an available time domain position above, the transmission unit 102, within that time domain period, The transmission blocks TB1, TB2, and TB3 from the 4th position (their RVs are 2, respectively) 3 and 1 are transmitted sequentially.

[0054] For example, after transmitting the first transmission block, the transmission unit 102 transmits a predetermined continuous time portion It was detected that there are j available time-domain locations within the time-domain period to which the current location belongs. In this case, j transmission blocks from the second transmission block at j available time domain positions The 'k' is transmitted sequentially, and within the next time-domain period of the same type as the time-domain period, the 'repK' is transmitted from the first to the next 'repK'. The transmission blocks that were not transmitted within the time domain period of the first transmission block are sequentially transmitted. It is configured to either transmit the transmission or abandon the transmission of transmission blocks that were not transmitted. This is possible, and j is greater than or equal to 0 and less than repK-1.

[0055] For example, as shown in Figure 6, after transmitting the first transmission block, repeated transmission The predetermined continuous time domain position belongs within the time domain period CG-perood_0 where j=2 Since there are two available time domain positions, the transmission unit 102 uses these two available time domains At the local location, two transmission blocks from the second transmission block, namely TB1 and TB2 ( The RVs (which are 2 and 3 respectively) are transmitted sequentially, and the same type as the time-domain period. Within the next time-domain period CG-perood_0, the fourth transmission block TB3 (its RV is It transmits (which is 1).

[0056] Figure 7 shows the transmitted transmission block according to the embodiment of this disclosure, and the corresponding transmission block. Another schematic diagram of redundant version numbers is shown. The difference between Figure 7 and Figure 6 is that in Figure 6, the following is shown. Regarding TB3 transmitted within the time domain period CG-perood_0, CG-pero od_0 is a different type of CG-perood_1 (i.e., repeated by electronic device 100) Figure 7 clearly shows that the TB3 cannot be transmitted within the time domain period (which is not allocated to transmission). For example, the transmission unit 102 may abandon the transmission of the TB3.

[0057] As can be seen from the above explanation, in the repeated transmission described in Figures 5 to 7, the transmission section 102 shifts the entire transmission block that was not sent due to channel detection failure. do.

[0058] For example, the determination unit 104 determines the first number of repeated transmissions repK when an electronic device is selected. The second number of repeated transmissions, repK', was modified, and the first redundant version pattern was changed electronically. The device can be configured to modify to a selected second redundant version pattern. In this way, the electronic device 100 has selected a second number of repeated transmissions, and the second By repeatedly transmitting transmission blocks according to the redundant version pattern, This can improve the transmission selection rights of the slave device 100.

[0059] For example, the second redundant version pattern is the redundant version sequence {0,2,3, It can be one of {1}, {0,3,0,3}, and {0,0,0,0}.

[0060] For example, the second number of repeated transmissions repK' is equal to the first number of repeated transmissions repK. If the second redundant version pattern is not equal to the first redundant version pattern, and / or if the second redundant version pattern is not equal to the first redundant version pattern, then... It is not equal to .

[0061] For example, the determination unit 104 determines the second redundant version pattern (mod(m-1 The 4th (+1)th data point is used as the redundant version number corresponding to the mth transmission block. It can be configured such that mod() is the modulo operation, and m is greater than or equal to 1 and less than or equal to repK'. It is an integer. In this way, the redundant version number corresponding to each transmission block can be easily obtained. It can be easily determined.

[0062] For example, the determination unit 104 determines the remaining time domain period to which a predetermined continuous time domain position belongs. Based on the number of available time-domain positions, the second number of repeated transmissions repK' and the second It can be configured to select a redundant version pattern. Those skilled in the art will know the second redundant version Other methods for selecting the number of repeat transmissions repK' and a second redundant version pattern have been conceived. It is also possible to do so, so there will be no duplication here.

[0063] For example, the determination unit 104 determines the second number of repeated transmissions and the second redundant version pattern. It can be configured to add the uplink control instruction UCI and transmit it to the base station. In other words, the determination unit 104 determines the corrected first number of repeated transmissions (i.e., repK'). ), and the modified first redundant version pattern (i.e., the second redundant version pattern) The (n) can be added to the uplink control instruction UCI and transmitted to the base station.

[0064] For example, the transmission unit 102 rep within the time domain period to which a predetermined continuous time domain position belongs If it is detected that there is an available time domain position greater than or equal to K', a predetermined continuous time domain Starting from the nth time domain location detected as available among the locations, the time The system is configured to sequentially transmit transmission blocks from the 1st to the repK'th within the domain period. It is possible to do so.

[0065] Figure 8 shows the transmitted transmission block according to the disclosed embodiment, and the corresponding redundancy of the transmission block. Another schematic diagram of the long version number is shown. In Figure 8, repK=4, and the first The redundant version pattern is the redundant version sequence {0,2,3,1}, and re pK'=2, and the second redundant version pattern is the redundant version sequence {0, 3,0,3}. Note that repK and the first redundant version pattern are RRC (wireless). It is composed of resource control.

[0066] As shown in Figure 8, the transmission unit 102 is a repeating transmission pre-configured by the base station. The first three (i.e., the 1st to the 3rd) of the predetermined continuous time domain positions that can be used If it is discovered that the channel is busy at an inter-domain location, the first three time-domain locations Abandon transmission of the first to third transmission blocks TB0-TB2.

[0067] Then, the transmission unit 102 is the fourth of the predetermined continuous time domain positions for repeated transmission. If the channel is successfully detected as idle at the time domain position of the eye, then the fourth time Starting from the intermediate region position, the number of repeated transmissions is based on the second redundant version pattern. The transmission is repeated as repK'.

[0068] The transmission unit 102 is a predetermined unit that can be used for repeated transmission and is pre-configured by the base station. Two or more available within the time domain period CG-period_0 to which the continuous time domain position belongs. If a time-domain position is detected, start from the fourth time-domain position mentioned above. Then, the first to second transmission blocks are transmitted sequentially within the time domain period. (See Figure 8) As shown, the transmission unit 102 starts from the fourth time domain position described above and transmits the first transmission Block TB0 (and its corresponding redundant version number is the second redundant version pattern) The first data in, i.e., RV=0), and TB1 (the corresponding redundant ba The version number is the second data in the second redundant version pattern, i.e., Transmit RV=3).

[0069] For example, the transmission unit 102 has k units within the time domain period to which a predetermined continuous time domain position belongs. If an available time domain location is detected, among the predetermined continuous time domain locations, Starting from the nth time-domain position above that was detected as available, within the time-domain period 1 Transmission blocks from the nth to the kth are transmitted sequentially, and the next time is of the same type as the time domain period. Within the time domain period, transmission blocks from the 1st to repK' are sent within the time domain period. Transmit the unsent transmission blocks sequentially, or transmit the transmission blocks that were not sent. The transmission may be abandoned, and k is greater than or equal to 0 and less than repK'.

[0070] The above describes the repK pre-configured by the base station and the first redundant version pattern. This was explained. However, the base station uses repK and the first redundant version pattern. It is not necessary to configure the base station in advance. The base station configures repK and the first redundant version pattern. If not configured, the electronic device 100 will use the UCI that is carried when transmitting each transmission block. The number of transmission repetitions and redundant version patterns used in this transmission were then sent to the base station. In this case, UCI can be informed of two patterns: the number of repeated transmissions and the redundant version pattern. We need to add a lameter.

When performing repeated transmission, a predetermined network configured by the base station for repeated transmission If the first n-1 consecutive time-domain positions among the consecutive time-domain positions are unavailable, then the nth position When a time-domain position is detected as available, start from the nth time-domain position. Then, at least some of the transmission blocks from the 1st to the repKth transmission block The transmission of the first redundant version pattern received from the base station will be repeated. Based on this, a redundant version number corresponding to each transmitted transmission block is determined, and repK n is the number of first repeated transmissions received from the base station, and n is 1 or greater and repK or less. The integer is shown below. Method 900 is terminated in step S906. Method 900 is U This can be executed on the E side.
