[0011] Hereinafter, exemplary embodiments of the present disclosure will be described with reference to the drawings. For clarity and brevity not all features of actual embodiments are described in the specification. For example, system and service pertaining to the limitations and these limitations may vary depending on the embodiment It should be understood that in the process of developing such actual embodiments, decisions must be made to specify the embodiments so as to achieve the specific goals of the developer. Also, although the development work may be very complex and time-consuming, it should also be understood that for those skilled in the art who benefit from the content of the present disclosure such development work is just an everyday task.

[0012] Here, to avoid obscuring the present disclosure with unnecessary details, in the drawings, only the device configurations and / or processing steps closely related to the solution of the present disclosure are shown, and it should also be noted that other details that have little to do with the present disclosure are omitted.

[0013] Hereinafter, embodiments according to the present disclosure will be described in detail with reference to the drawings.

[0014] FIG. 1 shows a block diagram of functional modules of an electronic device 100 for wireless communication according to an embodiment of the present disclosure. As shown in FIG. 1, when the electronic device 100 performs repeated transmission including transmission blocks from the 1st to the repKth to a base station that provides services to the electronic device 100, if the first n - 1 consecutive time domain positions among the predetermined consecutive time domain positions for the repeated transmission configured by the base station are not available, the nth time domain position ​​​​​​​When it is detected that is available, starting from the nth time domain position, at least some of the transmission blocks among the transmission blocks from the first to the repKth are repeatedly transmitted, and the transmission unit 102 can be configured to perform the repeated transmission. And a determination unit 104 that can be configured to determine the redundancy version number corresponding to each transmitted transmission block based on the first redundancy version pattern received from the base station. Here, repK is the number of repeated transmissions received from the base station, and n is an integer greater than or equal to 1 and less than or equal to repK. It should be noted that the transmission unit 102 and the determination unit 104 can be realized by one or more processing circuits, and the processing circuit can be realized as a chip, for example. The electronic device 100 can be installed on the user equipment (UE) side, for example, or may be communicably connected to the UE. Here, the electronic device 100 can be realized at the chip level or at the device level. For example, the electronic device 100 can operate as the user equipment itself, and may further include external devices such as a memory and a transceiver (not shown). The memory is used to store programs and related data information that need to be executed for the user equipment to realize various functions. The transceiver can include one or more communication interfaces to support communication with different devices (such as base stations, other user equipment, etc.), but the specific implementation form of the transceiver is not specifically limited here. The base station can be, for example, a gNB.

[0015] When it is detected that is available, starting from the nth time domain position, at least some of the transmission blocks among the transmission blocks from the first to the repKth are repeatedly transmitted, and the transmission unit 102 can be configured to perform the repeated transmission. And a determination unit 104 that can be configured to determine the redundancy version number corresponding to each transmitted transmission block based on the first redundancy version pattern received from the base station. Here, repK is the number of repeated transmissions received from the base station, and n is an integer greater than or equal to 1 and less than or equal to repK.

[0016] The electronic device 100 can be installed on the user equipment (UE) side, for example, or may be communicably connected to the UE. Here, the electronic device 100 can be realized at the chip level or at the device level. For example, the electronic device 100 can operate as the user equipment itself, and may further include external devices such as a memory and a transceiver (not shown). The memory is used to store programs and related data information that need to be executed for the user equipment to realize various functions. The transceiver can include one or more communication interfaces to support communication with different devices (such as base stations, other user equipment, etc.), but the specific implementation form of the transceiver is not specifically limited here. The base station can be, for example, a gNB. When it is detected that is available, starting from the nth time domain position, at least some of the transmission blocks among the transmission blocks from the first to the repKth are repeatedly transmitted, and the transmission unit 102 can be configured to perform the repeated transmission. And a determination unit 104 that can be configured to determine the redundancy version number corresponding to each transmitted transmission block based on the first redundancy version pattern received from the base station. Here, repK is the number of repeated transmissions received from the base station, and n is an integer greater than or equal to 1 and less than or equal to repK. It should be noted that the transmission unit 102 and the determination unit 104 can be realized by one or more processing circuits, and the processing circuit can be realized as a chip, for example. The electronic device 100 can be installed on the user equipment (UE) side, for example, or may be communicably connected to the UE. Here, the electronic device 100 can be realized at the chip level or at the device level. For example, the electronic device 100 can operate as the user equipment itself, and may further include external devices such as a memory and a transceiver (not shown). The memory is used to store programs and related data information that need to be executed for the user equipment to realize various functions. The transceiver can include one or more communication interfaces to support communication with different devices (such as base stations, other user equipment, etc.), but the specific implementation form of the transceiver is not specifically limited here. The base station can be, for example, a gNB.

[0017] The base station can be, for example, a gNB.

[0018] As an example, the above-mentioned predetermined continuous time domain position is a radio resource control (RRC) configured grant (CG) time domain position pre-assigned by a base station. As an example, the number of the above-mentioned predetermined continuous time domain positions is equal to or greater than repK. The CG time domain position may be referred to as a CG resource, and the time domain period to which the predetermined continuous time domain position belongs may be referred to as a CG period. As an example, the transmission unit 102 may be configured to perform repeated transmission (which may also be referred to as redundant transmission) of a transmission block (TB) in a non-licensed band in a scheduling-free manner. As an example, the transmission unit 102 may be configured to perform repeated transmission of a transmission block by means of a hybrid automatic repeat request (HARQ) process. Communication in a non-licensed band adopts a fair competition mechanism for channel occupancy. After obtaining configuration information regarding available resources within a CG period by a base station, a UE performs channel idle detection and attempts to occupy pre-configured resources for data transmission.

[0019] However, when it is discovered that the channel is busy at a pre-configured time domain position where the UE can access the channel, the UE cannot transmit a transmission block at the above-mentioned time domain position for repeated transmission configured by the base station. Channel detection may be, for example, listen before talk (LBT). As an example, at least some of the time domain positions pre-assigned by a base station may be unable to perform transmission of a transmission block due to an LBT failure. As an example, for example, LBT may be performed on a pre-configured time domain position for a certain period of time. If the channel is detected as idle during this period, the UE may transmit a transmission block at the pre-configured time domain position.

[0020] However, if it is detected that the channel is busy during this period, the UE needs to re-detect the channel or select another available time domain position for transmission. In the case of a non-licensed band, since there is no license for spectrum resources, in order to ensure fair access to the channel, a contention-based mechanism needs to be adopted. For example, the UE may perform a random backoff operation and then attempt to access the channel again after a certain period of time. In addition, the base station may also adjust the configuration parameters of the CG according to the channel conditions and the number of UEs accessing the non-licensed band to ensure efficient use of the spectrum resources. For example, the base station may reduce the CG period or the number of available CG time domain positions when the channel is congested. On the other hand, when the channel conditions are good, the base station may increase the CG period or the number of available CG time domain positions to improve the data transmission rate. In summary, communication in a non-licensed band needs to balance spectrum resource utilization and fairness through a series of mechanisms and strategies to ensure reliable data transmission. As an example, at least some of the time domain positions pre-assigned by a base station may be unable to perform transmission of a transmission block due to an LBT failure. As an example, for example, LBT may be performed on a pre-configured time domain position for a certain period of time. Due to the failure, the first n - 1 consecutive time - domain positions among the predetermined consecutive time - domain positions for the repeated transmission constituted by the base station become unavailable. Therefore, it is impossible to transmit the transmission block at the above - mentioned first n - 1 consecutive time - domain positions. When it is detected that the n - th time - domain position among the above - mentioned predetermined consecutive time - domain positions is available, the transmission unit 102 starts from the n - th time - domain position and repeats the transmission of at least some of the transmission blocks among the transmission blocks from the 1st to the r epK - th. For example, the transmission unit 102 repeats the transmission of at least some of the transmission blocks at consecutive time positions starting from the n - th time - domain position.

[0021] As an example, the first redundancy version pattern can be one of the redundancy version sequences {0, 2, 3, 1}, {0, 3, 0, 3}, and {0, 0, 0, 0}. Based on the first redundancy version pattern, the determination unit 104 can determine the redundancy version number corresponding to each transmitted transmission block. When the electronic device 100 according to the embodiment of the present disclosure discovers that the channel is busy at some time - domain positions accessing a channel pre - configured by the base station, it repeats the transmission of the transmission block only after a usable time - domain position is detected, can determine the redundancy version number of the transmitted transmission block, and the base station can effectively perform combined decoding after receiving the redundant transmission.

[0025] ​​​​​​​​​​As an example, the determination unit 104 may be configured such that the (mod(n - 1 , 4)+1)-th data in the first redundant version pattern is the redundant version number corresponding to the n-th transmission block, where mod() is the remainder operation. In this way, the redundant version number corresponding to each transmission block can be determined simply and easily.

[0026] Taking repK = 4 and the first redundant version pattern being the redundant version sequence {0, 2, 3, 1} as an example, when n = 1, the redundant version number corresponding to the first transmission block TB0 is the first data in the first redundant version pattern, i.e., the redundant version number is 0.

In the case of n = 4, the redundant version number corresponding to the fourth transmission block TB3 is the fourth data in the first redundant version pattern, that is, the redundant version number is 3. That is, the redundant version number is 3.

[0028] Taking repK = 4 and the first redundant version pattern being the redundant version sequence {0, 0, 0, 0} as an example, in the case of n = 1, the redundant version number corresponding to the first transmission block TB0 is the first data in the first redundant version pattern, that is, the redundant version number is 0.

That is, the redundant version number is 0.

[0029] ​​As an example, the transmission unit 102 abandons the transmission of the first n - 1 transmission blocks among the first repK transmission blocks at the first n - 1 consecutive time domain positions out of the predetermined consecutive time domain positions, and starts from the nth time domain position among the predetermined consecutive time domain positions detected as available, and can be configured to transmit at least the nth transmission block. Among the first n - 1 transmission blocks among the first repK transmission blocks at the first n - 1 consecutive time domain positions and abandons the transmission of the first n - 1 transmission blocks among the first repK transmission blocks at the first n - 1 consecutive time domain positions out of the predetermined consecutive time domain positions, and starts from the nth time domain position among the predetermined consecutive time domain positions detected as available, and transmits at least the nth transmission block. Among the above, starting from the nth time domain position, at least the nth transmission block is transmitted. It can be configured as follows.

[0030] As an example, when the transmission unit 102 discovers that the channel is busy at the first n - 1 consecutive time domain positions among the predetermined consecutive time domain positions that can access the channel and are pre - configured by the base station, it abandons the transmission of the first n - 1 transmission blocks at the first n - 1 consecutive time domain positions. Also, the transmission unit 102 continuously performs channel detection within the CG period, and when it successfully detects that the channel is idle at the nth time domain position among the predetermined consecutive time domain positions for repeated transmission, it transmits the nth transmission block at the nth time domain position. Among the first n - 1 consecutive time domain positions of the predetermined consecutive time domain positions that can access the channel and are pre - configured by the base station, when it discovers that the channel is busy, it abandons the transmission of the first n - 1 transmission blocks at the first n - 1 consecutive time domain positions. Among the first n - 1 consecutive time domain positions of the predetermined consecutive time domain positions that can access the channel and are pre - configured by the base station, when it discovers that the channel is busy, it abandons the transmission of the first n - 1 transmission blocks at the first n - 1 consecutive time domain positions. Also, the transmission unit 102 continuously performs channel detection within the CG period, and when it successfully detects that the channel is idle at the nth time domain position among the predetermined consecutive time domain positions for repeated transmission, it transmits the nth transmission block at the nth time domain position. Among the predetermined consecutive time domain positions for repeated transmission, when it successfully detects that the channel is idle at the nth time domain position, it transmits the nth transmission block at the nth time domain position. When it successfully detects that the channel is idle at the nth time domain position among the predetermined consecutive time domain positions for repeated transmission, it transmits the nth transmission block at the nth time domain position. Transmits the nth transmission block at the nth time domain position.

[0031] The base station pre - assigns a plurality of time domain periods for repeated transmission to the electronic device 100. These periods are called time domain periods of the same type as the time domain period to which the predetermined consecutive time domain positions for the above - mentioned repeated transmission belong. In the following figures, each of the pre - assigned time domain periods for repeated transmission is marked as CG - period_0. The time domain periods not assigned to the repeated transmission of the electronic device 100 are called time domain periods of a different type from the time domain period to which the predetermined consecutive time domain positions for the above - mentioned repeated transmission belong, and the time domain periods not assigned to the repeated transmission of the electronic device 100 are C The base station pre - assigns a plurality of time domain periods for repeated transmission to the electronic device 100. These periods are called time domain periods of the same type as the time domain period to which the predetermined consecutive time domain positions for the above - mentioned repeated transmission belong. In the following figures, each of the pre - assigned time domain periods for repeated transmission is marked as CG - period_0. The time domain periods not assigned to the repeated transmission of the electronic device 100 are called time domain periods of a different type from the time domain period to which the predetermined consecutive time domain positions for the above - mentioned repeated transmission belong.

[0032] In FIGS. 2 to 8 described below, taking repK = 4 and the first redundant version pattern sequence being the redundant version sequence {0, 2, 3, 1} as an example, the time domain position marked with the first "X" in the first CG-period_0 in the figure is the first time domain position among the predetermined consecutive time domain positions that can be used for the repeated transmission preconfigured by the base station. Hereinafter, the consecutive time domain positions after the first time domain position are respectively referred to as the second time domain position, the third time domain position, the fourth time domain position, etc. among the predetermined consecutive time domain positions.

[0033] FIG. 2 shows a schematic diagram of a transmitted transmission block according to an embodiment of the present disclosure and the redundant version numbers corresponding to the transmission blocks.

[0034] In FIG. 2, when the transmission unit 102 discovers that the channel is busy at the first time domain position among the predetermined consecutive time domain positions that can be used for the repeated transmission preconfigured by the base station, the transmission of the first transmission block TB0 at the first time domain position is abandoned. Then, when the transmission unit 102 successfully detects that the channel is idle at the second time domain position among the predetermined consecutive time domain positions for the repeated transmission, the second transmission block TB1 is transmitted at the second time domain position. As described above, the redundant version number RV corresponding to the second transmission block TB1 is the second data in the first redundant version pattern, that is, RV = 2.

[0035] FIG. 3 shows another schematic diagram of the transmitted transport block according to an embodiment of the present disclosure and the redundancy version number corresponding to the transport block. When the transmission unit 102 discovers that the channel is busy at the first three (i.e., the first to the third) time domain positions among the predetermined consecutive time domain positions that can be used for repeated transmission preconfigured by the base station, the transmission of the first to third transport blocks TB0 - TB2 at the first three time domain positions is abandoned. Then, when the transmission unit 102 successfully detects that the channel is idle at the fourth time domain position among the predetermined consecutive time domain positions for repeated transmission, the fourth transport block TB3 is transmitted at the fourth time domain position. As described above, the redundancy version number corresponding to the fourth transport block TB3 is the fourth data in the first redundancy version pattern, i.e.,

[0036] FIG. 3 shows that when the transmission unit 102 discovers that the channel is busy at the first three (i.e., the first to the third) time domain positions among the predetermined consecutive time domain positions that can be used for repeated transmission preconfigured by the base station, the transmission of the first to third transport blocks TB0 - TB2 at the first three time domain positions is abandoned. Then, when the transmission unit 102 successfully detects that the channel is idle at the fourth time domain position among the predetermined consecutive time domain positions for repeated transmission, the fourth transport block TB3 is transmitted at the fourth time domain position. As described above, the redundancy version number corresponding to the fourth transport block TB3 is the fourth data in the first redundancy version pattern, i.e., RV = 1. When the transmission unit 102 discovers that the channel is busy at the first three (i.e., the first to the third) time domain positions among the predetermined consecutive time domain positions that can be used for repeated transmission preconfigured by the base station, the transmission of the first to third transport blocks TB0 - TB2 at the first three time domain positions is abandoned. Then, when the transmission unit 102 successfully detects that the channel is idle at the fourth time domain position among the predetermined consecutive time domain positions for repeated transmission, the fourth transport block TB3 is transmitted at the fourth time domain position. As described above, the redundancy version number corresponding to the fourth transport block TB3 is the fourth data in the first redundancy version pattern, i.e., RV = 1. When the transmission unit 102 discovers that the channel is busy at the first three (i.e., the first to the third) time domain positions among the predetermined consecutive time domain positions that can be used for repeated transmission preconfigured by the base station, the transmission of the first to third transport blocks TB0 - TB2 at the first three time domain positions is abandoned. Then, when the transmission unit 102 successfully detects that the channel is idle at the fourth time domain position among the predetermined consecutive time domain positions for repeated transmission, the fourth transport block TB3 is transmitted at the fourth time domain position. As described above, the redundancy version number corresponding to the fourth transport block TB3 is the fourth data in the first redundancy version pattern, i.e., RV = 1. RV = 1. RV = 1. RV = 1.

[0037] As an example, after the transmission unit 102 sequentially transmits the transport blocks from the nth to the repKth at the available time domain positions of the predetermined consecutive time domain positions, when it is detected that there are i additional available time domain positions within the time domain period to which the predetermined consecutive time domain positions belong, the first i transport blocks among the first n - 1 abandoned transport blocks are sequentially transmitted using the i additional available time domain positions, and the transport blocks that were not transmitted within the time domain period among the transport blocks from the first to the repKth at the available time domain positions within the next time domain period of the same type as the time domain period are sequentially transmitted, or the transmission of the transport blocks that were not transmitted can be abandoned. i is greater than or equal to 0 and When the transmission unit 102 discovers that the channel is busy at the first three (i.e., the first to the third) time domain positions among the predetermined consecutive time domain positions that can be used for repeated transmission preconfigured by the base station, the transmission of the first to third transport blocks TB0 - TB2 at the first three time domain positions is abandoned. Then, when the transmission unit 102 successfully detects that the channel is idle at the fourth time domain position among the predetermined consecutive time domain positions for repeated transmission, the fourth transport block TB3 is transmitted at the fourth time domain position. As described above, the redundancy version number corresponding to the fourth transport block TB3 is the fourth data in the first redundancy version pattern, i.e., RV = 1. When the transmission unit 102 discovers that the channel is busy at the first three (i.e., the first to the third) time domain positions among the predetermined consecutive time domain positions that can be used for repeated transmission preconfigured by the base station, the transmission of the first to third transport blocks TB0 - TB2 at the first three time domain positions is abandoned. Then, when the transmission unit 102 successfully detects that the channel is idle at the fourth time domain position among the predetermined consecutive time domain positions for repeated transmission, the fourth transport block TB3 is transmitted at the fourth time domain position. As described above, the redundancy version number corresponding to the fourth transport block TB3 is the fourth data in the first redundancy version pattern, i.e., RV = 1. When the transmission unit 102 discovers that the channel is busy at the first three (i.e., the first to the third) time domain positions among the predetermined consecutive time domain positions that can be used for repeated transmission preconfigured by the base station, the transmission of the first to third transport blocks TB0 - TB2 at the first three time domain positions is abandoned. Then, when the transmission unit 102 successfully detects that the channel is idle at the fourth time domain position among the predetermined consecutive time domain positions for repeated transmission, the fourth transport block TB3 is transmitted at the fourth time domain position. As described above, the redundancy version number corresponding to the fourth transport block TB3 is the fourth data in the first redundancy version pattern, i.e., RV = 1. RV = 1. It is less than n - 1.

[0038] After the transmission unit 102 transmits the nth transmission block at the above-mentioned nth time domain position, the electronic device 100 continues to occupy the channel, and thereby sequentially transmits the transmission blocks after the nth transmission block. After transmitting the repKth transmission block, if there is an additional available time domain position within the time domain period, the transmission unit 102 shifts and transmits the transmission blocks that were not transmitted due to the failure of channel detection after the repKth transmission block.

[0039] As an example, if all of the transmission blocks that were not transmitted due to the failure of channel detection can be transmitted at the above-mentioned additional available time domain position, the transmission unit 102 transmits all of the transmission blocks that were not transmitted due to the failure of channel detection within the time domain period.

[0040] As shown in FIG. 2, after the transmission unit 102 transmits the second transmission block TB1 within the time domain period CG - perood_0, it continuously transmits TB2 - TB3 (the RVs of TB2 - TB3 are 3 and 1, respectively). After transmitting TB1 - TB3, if there is an additional available time domain position within the time domain period and the additional available time domain position is sufficient to transmit TB0 that was not transmitted due to the failure of the above-mentioned channel detection, the transmission unit 102 shifts TB0 after TB3 and transmits TB0 within the time domain period.

[0041] As an example, the above-mentioned additional available time domain position is due to the failure of channel detection ​​​​​​​When it is not sufficient to transmit all of the transmission blocks that have not been transmitted, the transmission unit 102 transmits a part of the transmission blocks that have not been transmitted due to the failure of channel detection within the time domain period, and transmits the remaining transmission blocks of the transmission blocks that have not been transmitted due to the failure of channel detection at the available time domain positions within the next time domain period of the same type as the time domain period, so as to ensure that the transmission blocks from the first to the repK-th are completely transmitted. It should be noted that the transmission unit 102 shall not transmit the transmission blocks transmitted by the electronic device 100 within a time domain period of a type different from the time domain period. As shown in FIG. 3, after the transmission unit 102 transmits TB3 within the time domain period CG-perood_0, although there are additional available time domain positions within the time domain period, the additional available time domain positions are not sufficient to transmit TB0-TB2 that have not been transmitted due to the failure of channel detection. Therefore, the transmission unit 102 shifts TB0-TB1 (RVs are 0 and 2 respectively) and transmits them within the time domain period after TB3, and transmits TB2 (RV is 3) within the next time domain period CG-perood_0.

[0042] As shown in FIG. 3, after the transmission unit 102 transmits TB3 within the time domain period CG-perood_0, although there are additional available time domain positions within the time domain period, the additional available time domain positions are not sufficient to transmit TB0-TB2 that have not been transmitted due to the failure of channel detection. Therefore, the transmission unit 102 shifts TB0-TB1 (RVs are 0 and 2 respectively) and transmits them within the time domain period after TB3, and transmits TB2 (RV is 3) within the next time domain period CG-perood_0.

[0043] FIG. 4 shows another schematic diagram of the transmitted transmission blocks according to the embodiments of the present disclosure and the redundant version numbers corresponding to the transmission blocks. The difference between FIG. 4 and FIG. 3 is that for TB2 transmitted within the next time domain period CG-perood_0 in FIG. 3, CG-pero od_0 is of a different type from CG-perood_1 (i.e., the repetition by the electronic device 100 od_0 and CG-perood_1 of a different type (i.e., the repetition by the electronic device 100 ​​​​​​​​It is emphasized in FIG. 4 that the TB2 cannot be transmitted within the time domain period not allocated to downlink transmission. As an example, the transmission unit 102 can abandon the transmission of the TB2. As can be seen from the above description, in the repeated transmission described with reference to FIGS. 2 to 4 above, the transmission unit 102 circulates and shifts the transmission blocks not transmitted due to the failure of channel detection. As an example, the transmission unit 102 can be configured to start from the nth time domain position detected as available among the predetermined consecutive time domain positions and transmit at least the first transmission block.

[0044] As an example, when the transmission unit 102 discovers that the channel is busy at the first n - 1 consecutive time domain positions among the predetermined consecutive time domain positions pre - configured by the base station and accessible to the channel, it abandons the transmission of the first n - 1 transmission blocks among the first to repKth transmission blocks at the first n - 1 consecutive time domain positions. Then, the transmission unit 102 continuously performs channel detection within the CG period, and when it successfully detects that the channel is idle at the nth time domain position among the predetermined consecutive time domain positions for repeated transmission, it transmits the first transmission block at the nth time domain position. FIG. 5 shows another schematic diagram of the transmitted transmission block according to an embodiment of the present disclosure and the redundant version number corresponding to the transmission block.

[0048] ​​​​​​​​​​​​​In FIG. 5, when the transmission unit 102 discovers that the channel is busy at the first time domain position among the predetermined continuous time domain positions that can be used for repeated transmission and are preconfigured by the base station, it abandons the transmission of the first transmission block TB0 (with its RV = 0) at the first time domain position. Then, when the transmission unit 102 successfully detects that the channel is idle at the second time domain position among the predetermined continuous time domain positions for repeated transmission, it transmits the abandoned first transmission block (with its RV = 0) at the second time domain position. When it is discovered that the channel is busy at the first time domain position among the predetermined continuous time domain positions that can be used for repeated transmission and are preconfigured by the base station, the transmission of the first transmission block TB0 (with its RV = 0) at the first time domain position is abandoned. And then, when the transmission unit 102 successfully detects that the channel is idle at the second time domain position among the predetermined continuous time domain positions for repeated transmission, it transmits the abandoned first transmission block (with its RV = 0) at the second time domain position. When it is successfully detected that the channel is idle at the second time domain position, the abandoned first transmission block (with its RV = 0) is transmitted at the second time domain position.

[0049] FIG. 6 shows another schematic diagram of the transmitted transmission block according to an embodiment of the present disclosure and the redundant version number corresponding to the transmission block.

[0050] In FIG. 6, when the transmission unit 102 discovers that the channel is busy at the first to third time domain positions among the predetermined continuous time domain positions that can be used for repeated transmission and are preconfigured by the base station, it abandons the transmission of the first transmission block TB0 (with its RV = 0) at the first to third time domain positions. When the transmission unit 102 successfully detects that the channel is idle at the fourth time domain position among the predetermined continuous time domain positions for repeated transmission, it transmits the abandoned first transmission block (with its RV = 0) at the fourth time domain position. When it is discovered that the channel is busy at the first to third time domain positions among the predetermined continuous time domain positions that can be used for repeated transmission and are preconfigured by the base station, the transmission of the first transmission block TB0 (with its RV = 0) at the first to third time domain positions is abandoned. The transmission unit 102 abandons the transmission of the first transmission block TB0 (with its RV = 0). When the transmission unit 102 successfully detects that the channel is idle at the fourth time domain position among the predetermined continuous time domain positions for repeated transmission, it transmits the abandoned first transmission block (with its RV = 0) at the fourth time domain position.

[0051] As an example, after transmitting the first transmission block, when it is detected that there are available time domain positions of repK - 1 or more within the time domain period to which the predetermined continuous time domain position belongs, the transmission unit 102 transmits the second to repK-th transmission blocks within the time domain period. ​ can be configured to sequentially transmit.

[0052] After the transmission unit 102 transmits the first transmission block at the above-described n-th time domain position, the electronic device 100 continues to occupy the channel, whereby the subsequent transmissions after the first transmission block sequentially transmit the transmission blocks.

[0053] As an example, as shown in FIG. 5, after transmitting the first transmission block, within the time domain period CG-perood_0 to which the predetermined consecutive time domain positions for repeated transmission belong, since there are three or more available time domain positions, the transmission unit 102, within the time domain period, sequentially transmits the second to fourth transmission blocks TB1, TB2, TB3 (whose RVs are 2, 3, 1 respectively). As an example, after the transmission unit 102 transmits the first transmission block, when it is detected that there are j available time domain positions within the time domain period to which the predetermined consecutive time domain positions belong, the transmission unit 102 sequentially transmits j transmission blocks starting from the second transmission block at the j available time domain positions, and within the next time domain period of the same type as the time domain period, sequentially transmits the transmission blocks among the first to repK-th transmission blocks that were not transmitted within the time domain period, or can be configured to abandon the transmission of the transmission blocks that were not transmitted, where j is 0 or more and less than repK - 1. 3, 1 respectively). 3, 1 respectively).

[0054] As an example, after the transmission unit 102 transmits the first transmission block, when it is detected that there are j available time domain positions within the time domain period to which the predetermined consecutive time domain positions belong, the transmission unit 102 sequentially transmits j transmission blocks starting from the second transmission block at the j available time domain positions, and within the next time domain period of the same type as the time domain period, sequentially transmits the transmission blocks among the first to repK-th transmission blocks that were not transmitted within the time domain period, or can be configured to abandon the transmission of the transmission blocks that were not transmitted, where j is 0 or more and less than repK - 1. As an example, after the transmission unit 102 transmits the first transmission block, when it is detected that there are j available time domain positions within the time domain period to which the predetermined consecutive time domain positions belong, the transmission unit 102 sequentially transmits j transmission blocks starting from the second transmission block at the j available time domain positions, and within the next time domain period of the same type as the time domain period, sequentially transmits the transmission blocks among the first to repK-th transmission blocks that were not transmitted within the time domain period, or can be configured to abandon the transmission of the transmission blocks that were not transmitted, where j is 0 or more and less than repK - 1. As an example, after the transmission unit 102 transmits the first transmission block, when it is detected that there are j available time domain positions within the time domain period to which the predetermined consecutive time domain positions belong, the transmission unit 102 sequentially transmits j transmission blocks starting from the second transmission block at the j available time domain positions, and within the next time domain period of the same type as the time domain period, sequentially transmits the transmission blocks among the first to repK-th transmission blocks that were not transmitted within the time domain period, or can be configured to abandon the transmission of the transmission blocks that were not transmitted, where j is 0 or more and less than repK - 1. As an example, after the transmission unit 102 transmits the first transmission block, when it is detected that there are j available time domain positions within the time domain period to which the predetermined consecutive time domain positions belong, the transmission unit 102 sequentially transmits j transmission blocks starting from the second transmission block at the j available time domain positions, and within the next time domain period of the same type as the time domain period, sequentially transmits the transmission blocks among the first to repK-th transmission blocks that were not transmitted within the time domain period, or can be configured to abandon the transmission of the transmission blocks that were not transmitted, where j is 0 or more and less than repK - 1. As an example, after the transmission unit 102 transmits the first transmission block, when it is detected that there are j available time domain positions within the time domain period to which the predetermined consecutive time domain positions belong, the transmission unit 102 sequentially transmits j transmission blocks starting from the second transmission block at the j available time domain positions, and within the next time domain period of the same type as the time domain period, sequentially transmits the transmission blocks among the first to repK-th transmission blocks that were not transmitted within the time domain period, or can be configured to abandon the transmission of the transmission blocks that were not transmitted, where j is 0 or more and less than repK - 1. As an example, after the transmission unit 102 transmits the first transmission block, when it is detected that there are j available time domain positions within the time domain period to which the predetermined consecutive time domain positions belong, the transmission unit 102 sequentially transmits j transmission blocks starting from the second transmission block at the j available time domain positions, and within the next time domain period of the same type as the time domain period, sequentially transmits the transmission blocks among the first to repK-th transmission blocks that were not transmitted within the time domain period, or can be configured to abandon the transmission of the transmission blocks that were not transmitted, where j is 0 or more and less than repK - 1. As an example, after the transmission unit 102 transmits the first transmission block, when it is detected that there are j available time domain positions within the time domain period to which the predetermined consecutive time domain positions belong, the transmission unit 102 sequentially transmits j transmission blocks starting from the second transmission block at the j available time domain positions, and within the next time domain period of the same type as the time domain period, sequentially transmits the transmission blocks among the first to repK-th transmission blocks that were not transmitted within the time domain period, or can be configured to abandon the transmission of the transmission blocks that were not transmitted, where j is 0 or more and less than repK - 1.

[0055] As an example, as shown in FIG. 6, after transmitting the first transmission block, within the time domain period CG-perood_0 to which the predetermined consecutive time domain positions for repeated transmission belong, where j = 2 As an example, after transmitting the first transmission block, within the time domain period CG-perood_0 to which the predetermined consecutive time domain positions for repeated transmission belong, where j = 2 Since there are two available time domain positions, the transmission unit 102 transmits two transmission blocks from the second transmission block at these two available time domain positions, namely, TB1 and TB2 (the RVs of which are 2 and 3 respectively) sequentially, and transmits the fourth transmission block TB3 (the RV of which is 1) within the next time domain period CG - perood_0 of the same type as the time domain period. The second transmission block from the second transmission block, i.e., TB1 and TB2 (the RVs of which are 2 and 3 respectively) are sequentially transmitted at these two available time domain positions, and the fourth transmission block TB3 (the RV of which is 1) is transmitted within the next time domain period CG - perood_0 of the same type as the time domain period. In FIG. 7, another schematic diagram of the transmitted transmission block according to an embodiment of the present disclosure and the redundancy version number corresponding to the transmission block is shown. The difference between FIG. 7 and FIG. 6 is that for TB3 transmitted within the next time domain period CG - perood_0 in FIG. 6, FIG. 7 emphasizes that the TB3 cannot be transmitted within a different type of CG - perood_1 (i.e., a time domain period not allocated for repeated transmission by the electronic device 100) from CG - pero od_0. For example, the transmission unit 102 can abandon the transmission of the TB3.

[0056] As can be seen from the above description, in the repeated transmission described in FIGS. 5 to 7, the transmission unit 102 shifts the transmission blocks not transmitted due to the failure of channel detection as a whole. For example, the determination unit 104 can be configured to correct the first repeated transmission count repK to the second repeated transmission count repK' selected by the electronic device, and correct the first redundancy version pattern to the second redundancy version pattern selected by the electronic device. In this way, the second repeated transmission count and the second redundancy version pattern selected by the electronic device 100 itself are emphasized in FIG. 7. For example, the transmission unit 102 can abandon the transmission of the TB3. As can be seen from the above description, in the repeated transmission described in FIGS. 5 to 7, the transmission unit 102 shifts the transmission blocks not transmitted due to the failure of channel detection as a whole.

[0057] As can be seen from the above description, in the repeated transmission described in FIGS. 5 to 7, the transmission unit 102 shifts the transmission blocks not transmitted due to the failure of channel detection as a whole. For example, the determination unit 104 can be configured to correct the first repeated transmission count repK to the second repeated transmission count repK' selected by the electronic device, and correct the first redundancy version pattern to the second redundancy version pattern selected by the electronic device. In this way, the second repeated transmission count and the second

[0058] redundancy version pattern selected by the electronic device 100 itself are emphasized in FIG. 7. For example, the transmission unit 102 can abandon the transmission of the TB3. redundancy version pattern selected by the electronic device 100 itself are emphasized in FIG. 7. For example, the transmission unit 102 can abandon the transmission of the TB3. According to the redundant version pattern, by performing repeated transmission of the transport block, the transmission selection right of the electronic device 100 can be improved.

[0059] As an example, the second redundant version pattern can be one of the redundant version sequences {0, 2, 3, 1}, {0, 3, 0, 3}, and {0, 0, 0, 0}.

[0060] As an example, the second number of repeated transmissions repK' is not equal to the first number of repeated transmissions repK, and / or the second redundant version pattern is not equal to the first redundant version pattern.

[0061] As an example, the determination unit 104 can be configured such that the data at the ((mod(m - 1, 4)+1)-th) position in the second redundant version pattern is the redundant version number corresponding to the m-th transport block, where mod() is the remainder operation and m is an integer greater than or equal to 1 and less than or equal to repK'. In this way, the redundant version number corresponding to each transport block can be determined simply and easily.

[0062] As an example, the determination unit 104 can be configured to select the second number of repeated transmissions repK' and the second redundant version pattern based on the number of available time domain positions remaining within the time domain period to which a predetermined continuous time domain position belongs. Those skilled in the art can also conceive of other methods for selecting the second number of repeated transmissions repK' and the second redundant version pattern, so there is no need to repeat here.

[0063] As an example, the determination unit 104 is the second number of repeated transmissions and the second redundant version pattern configured to add it to the uplink control indication UCI and transmit it to the base station That is, the determination unit 104 can add the modified first repetition transmission count (i.e., repK’) , and the modified first redundancy version pattern (i.e., the second redundancy version pattern) to the uplink control indication UCI and transmit it to the base station.

[0064] As an example, when it is detected that there are available time domain positions of repK’ or more within the time domain period to which a predetermined continuous time domain position belongs, the transmission unit 102 starts from the above-mentioned nth time domain position detected as available among the predetermined continuous time domain positions, and can be configured to sequentially transmit transmission blocks from the 1st to the repK’th within the time domain period.

[0065] FIG. 8 shows another schematic diagram of the transmitted transmission block according to the disclosed embodiment and the redundancy version number corresponding to the transmission block. In FIG. 8, repK = 4, the first redundancy version pattern is the redundancy version sequence {0, 2, 3, 1}, repK’ = 2, and the second redundancy version pattern is the redundancy version sequence {0, 3, 0, 3}. Note that repK and the first redundancy version pattern are configured by RRC (Radio Resource Control).

[0066] As shown in FIG. 8, when the transmission unit 102 discovers that the channel is busy at the first three (i.e., the 1st to the 3rd) time domain positions among the predetermined continuous time domain positions that can be used for repeated transmission and are preconfigured by the base station, the first three time domain positions ​​​​​​​​​Abort the transmission of the first to third transmission blocks TB0 - TB2.

[0067] Then, when the transmission unit 102 successfully detects that the channel is idle at the fourth time domain position among the predetermined continuous time domain positions for retransmission, starting from the fourth time domain position, perform retransmission based on the second redundant version pattern with the number of retransmission times being repK’.

[0068] The transmission unit 102 is within the time domain period CG - period_0 to which the predetermined continuous time domain positions configured in advance by the base station and available for retransmission belong, and when it is detected that there are two or more available time domain positions, starting from the above - mentioned fourth time domain position, sequentially transmit the first to second transmission blocks within the time domain period. As shown in FIG. 8, starting from the above - mentioned fourth time domain position, the transmission unit 102 transmits the first transmission block TB0 (the corresponding redundant version number is the first data in the second redundant version pattern, that is, RV = 0), and TB1 (the corresponding redundant version number is the second data in the second redundant version pattern, that is, RV = 3).

[0069] As an example, when the transmission unit 102 detects that there are k available time domain positions within the time domain period to which the predetermined continuous time domain positions belong, starting from the above - mentioned nth time domain position detected as available among the predetermined continuous time domain positions, sequentially transmit the first to kth transmission blocks within the time domain period, and the next time domain period of the same type as the time domain period Among the transmission blocks from the 1st to the repK’th within the domain period, transmit the transmission blocks that were not transmitted within the time domain period in sequence, or abandon the transmission of the transmission blocks that were not transmitted. Here, k is 0 or more and less than repK’. The above has been described with respect to repK preconfigured by the base station and the first redundant version pattern. However, the base station may not preconfigure repK and the first redundant version pattern. If the base station does not configure repK and the first redundant version pattern, the electronic device 100 can notify the base station of the number of repeated transmissions and the redundant version pattern used in this transmission through the UCI carried when transmitting each transmission block. In this case, it is necessary to add two parameters, the number of repeated transmissions and the redundant version pattern, to the UCI.

[0070]

[0071] In the process of describing the electronic device for wireless communication in the above embodiments, several obvious processes or methods were disclosed. The following is a description of the outlines of these methods without repeating some details already discussed above. These methods were disclosed in the process of describing the electronic device for wireless communication, but do not necessarily use the members described or be implemented by these members. For example, the embodiments of the electronic device for wireless communication can be realized partially or completely by hardware and / or firmware, and the following methods for wireless communication can be realized by a completely computer-executable program. Of course, these methods may also utilize the hardware and / or firmware of the electronic device for wireless communication.​​​​​​​​​​​​​​​​

[0072] FIG. 9 shows a flowchart of a method 900 for wireless communication according to an embodiment of the present disclosure. The method 900 starts from step S902. In step S904, when performing repeated transmission including transmission blocks from the first to the repK-th to a base station that provides services to an electronic device, if the first n - 1 consecutive time domain positions among predetermined consecutive time domain positions for repeated transmission configured by the base station are unavailable, when it is detected that the n-th time domain position is available, starting from the n-th time domain position, repeated transmission of at least some of the transmission blocks from the first to the repK-th is performed. Note that, based on the first redundancy version pattern received from the base station, a redundancy version number corresponding to each transmitted transmission block is determined, and repK is the first number of repeated transmission times received from the base station, and n is an integer greater than or equal to 1 and less than or equal to repK. The method 900 ends at step S906. The method 900 can be executed on the UE side. The method can be executed, for example, by the electronic device 100 described in the first embodiment. For specific details, reference can be made to the corresponding descriptions above, and thus will not be repeated here.

[0073] The technology of the present disclosure is applicable to various products. For example, the electronic device 100 can be realized as various user devices. The user device

[0074] is, for example, a mobile terminal (e.g., a smartphone, a tablet personal computer (PC),

[0075] ​​​A notebook PC, a portable game terminal, a mobile router of a portable / dongle type, and a digital camera device), or may be implemented as an in-vehicle terminal (e.g., a car navigation device). The user equipment may further be a terminal for performing M2M (Machine To Machine) communication (also referred to as an MTC (Machine Type Communication) terminal). In addition, the user equipment may be a wireless communication module (e.g., an integrated circuit module including a single chip) mounted on each of these terminals.

[0076] [Application examples related to base stations] (First application example) FIG. 10 is a block diagram showing a first example of the schematic configuration of an eNB or a gNB to which the technology of the present disclosure can be applied. The following description is given by taking the eNB as an example, but it is similarly applicable to the gNB. The eNB 800 has one or more antennas 810 and a base station device 820. Each antenna 810 and the base station device 820 can be connected to each other via an RF cable. Each of the antennas 810 has a single or a plurality of antenna elements (e.g., a plurality of antenna elements included in a MIMO antenna), and is used for transmitting and receiving wireless signals by the base station device 820. As shown in FIG. 10, the eNB 800 can have a plurality of antennas 810. The plurality of antennas 810 can be compatible with, for example, a plurality of frequency bands used by the eNB 800. Although FIG. 10 shows an example in which the eNB 800 has a plurality of antennas 810, the eNB 800 may have a single antenna 810.

[0077]

[0078] The base station apparatus 820 includes a controller 821, a memory 822, a network interface 823, and a wireless communication interface 825.

[0079] The controller 821 can be, for example, a CPU or a DSP, and operates various functions of the upper layer of the base station apparatus 820. For example, the controller 821 generates data packets from the data in the signal processed by the wireless communication interface 825, and transfers the generated packets via the network interface 823. The controller 82 1 can generate bundled packets by bundling data from a plurality of baseband processors, and transfer the generated bundled packets. Also, the co ntroller 821 can have a logical function for performing controls such as radio resource control (Radio Resource Contro l), radio bearer control, mobility management (Mobility Management), admission control (Admissio n Control), or scheduling. Also, the control can be executed in cooperation with surrounding eNBs or core ne (Mobility Management), admission control (Admission Control), or scheduling. Also, the control can be executed in cooperation with surrounding eNBs or core network nodes. The memory 822 includes a RAM and a RO M, and stores programs executed by the controller 821 and various control data (e.g., a terminal list, transmission power data, and scheduling data, etc.). The network interface 823 is a communication interface for connecting the base station apparatus 820 to the core network 824. The controller 821 is connected to the network interface

[0080] 823, and a wireless communication interface 825. The controller 821 is connected to the network interface Communicate with a core network node or another eNB via the interface 823 This can be done. In that case, the eNB 800 and the core network node or another eNB are connected to each other via logical interfaces (e.g., S1 interface and X2 interface). The network interface 823 may be a wired communication interface or a wireless communication interface for a wireless backhaul line. When the network interface 823 is a wireless communication interface, the network interface 823 can use a higher frequency band for wireless communication than the frequency band used by the wireless communication interface 825.

[0081] The wireless communication interface 825 supports any cellular communication system (e.g., Long Term Evolution ( LTE) and LTE-Advanced) and provides a wireless connection to terminals located in the cell of the eNB 800 via the antenna 810. The wireless communication interface 825 usually may include, for example, a baseband (BB) processor 826 and an RF circuit 827. The BB processor 826 can perform, for example, encoding / decoding, modulation / demodulation, and multiplexing / demultiplexing, and can perform signal processing of each type of layer (e.g., L1, Media Access Control (MAC), Radio Link Control (RLC), Packet Data Aggregation Protocol (PDCP)). The BB processor 826 may have some or all of the above-described logical functions instead of the controller 821. The BB processor 826 may be a memory storing a communication control program, or may execute a program ​It may be a module including a processor configured to execute and associated circuits. The update of the program can change the functions of the BB processor 826. This module may be a card or a blade inserted into a slot of the base station apparatus 820. Alternatively, this module may be a chip mounted on a card or a blade. At the same time, the RF circuit 827 includes, for example, a mixer, a filter, and an amplifier, and can transmit and receive wireless signals through the antenna 810.

[0082] As shown in FIG. 10, the wireless communication interface 825 can include a plurality of BB processors 82 6. For example, the plurality of BB processors 826 can be compatible with a plurality of frequency bands used by the eNB 800. As shown in FIG. 10, the wireless communication interface 825 can include a plurality of RF circuits 827. For example, the plurality of RF circuits 827 can be compatible with a plurality of antenna elements. FIG. 10 shows an example in which the wireless communication interface 82 5 includes a plurality of BB processors 826 and a plurality of RF circuits 827, but the wireless communication interface 825 may include a single BB processor 826 or a single RF circuit 827.
