Technical Field

[0002] In related technologies, Transport Block Processing Over Multiple Slots (TBoMS) refers to the transmission of a Transport Block (TB) using multiple slots, with each slot transmitting only a portion of the encoded data from that TB. If a configured grant (CG) method is used for TBoMS repetition, since a TB occupies multiple slots for transmission, it is necessary to determine the slot positions that can be used to initiate the transmission. Summary of the Invention

Detailed Implementation

[0056] To facilitate understanding, the terminology used in this application will be introduced first.

[0057] 1. RV (Redundancy Version): This is used to implement incremental redundancy (IR) hybrid automatic repeat reQuest (HARQ) transmission. It divides the redundant bits generated by the encoder into several groups, and each RV defines a transmission start point. The first transmission and each subsequent HARQ retransmission use different RVs to gradually accumulate redundant bits and complete the incremental redundancy HARQ operation.

[0058] 2. MCS (Modulation and Coding Scheme). MCS uses the factors affecting communication rate as columns and the MCS indexes as rows to form a rate table. Each MCS index corresponds to a physical transmission rate under a set of parameters.

[0059] 3. Configured Grant (CG) for semi-static scheduling. Semi-static scheduling means that the base station configures a certain resource period for the terminal through RRC signaling, and the same time-frequency domain resources are used for data transmission in each period. This method can complete each data transmission without dynamic scheduling, which can reduce scheduling signaling overhead and help reduce transmission latency. The selectable range of CG periods includes: 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 160, 256, 320, 512, 640, 1024, 1280, 2560, and 5120 time slots.

[0060] To better understand the method for determining the starting transmission position of a TB disclosed in the embodiments of this application, the communication system to which the embodiments of this application are applicable is described below.

[0061] Please see Figure 1 , Figure 1 This application provides a schematic diagram of the architecture of a communication system according to an embodiment. The communication system may include, but is not limited to, a network device and a terminal device.

In actual applications, it may include two or more network devices and two or more terminal devices. Figure 1 The communication system shown is exemplified by a network device 101 and a terminal device 102.

[0062] It should be noted that the technical solutions of this application embodiment can be applied to various communication systems. For example, long term evolution (LTE) systems, 5th generation (5G) mobile communication systems, 5G new radio (NR) systems, or other future new mobile communication systems, etc.

[0063] The network device 101 in this embodiment is a network-side entity used for transmitting or receiving signals. For example, the network device 101 can be an evolved NodeB (eNB), a transmission reception point (TRP), a next-generation NodeB (gNB) in an NR system, a base station in other future mobile communication systems, or an access node in a wireless fidelity (WiFi) system. This application does not limit the specific technology or device form used in the network device. The network device provided in this embodiment can be composed of a central unit (CU) and a distributed unit (DU). The CU can also be called a control unit. Using a CU-DU structure allows the protocol layer of a network device, such as a base station, to be separated. Some protocol layer functions are centrally controlled by the CU, while the remaining or all protocol layer functions are distributed in the DU, which is centrally controlled by the CU.

[0064] In this application embodiment, the terminal device 102 is a user-side entity used to receive or transmit signals, such as a mobile phone. The terminal device can also be referred to as a terminal, user equipment (UE), mobile station (MS), mobile terminal (MT), etc. The terminal device can be a car with communication capabilities, a smart car, a mobile phone, a wearable device, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, a wireless terminal device in a smart home, and so on.

[0065] It is understood that the communication system described in the embodiments of this application is for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and does not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0066] It is understood that the multiple solutions in the embodiments of this application can be implemented individually or in combination, and this application does not limit them in this regard.

[0067] The method and apparatus for determining the starting transmission position of a TB, as provided in this application, will now be described in detail with reference to the accompanying drawings.

[0068] Please see Figure 2 , Figure 2 This is a flowchart illustrating a method for determining the starting transmission position of a TB according to an embodiment of this application, executed by a terminal device, such as... Figure 2 As shown, the method may include, but is not limited to, the following steps: S201, determine the redundant version RV sequence used to transmit multiple time slots of the same TB block within the CG period.

[0069] To avoid transmission conflicts between various terminal devices in a communication system, terminal devices can receive transmission scheduling from network devices. In a communication system, terminal devices and network devices can communicate in time slots corresponding to certain time and frequency resources of the channel. Each time slot can include multiple symbol periods and correspond to bandwidth. Each time slot can include a control channel for transmitting control information and a shared data channel for transmitting uplink and / or downlink data. Network devices can send scheduling grants on the control channel of a time slot, allocating some or all of the shared data channel of the time slot to terminal devices. Terminal devices can use the shared data channel to send or receive data according to the scheduling grants.

[0070] When a terminal device receives Radio Resource Control (RRC) signaling from a network device, it can parse the configuration authorization information from it, determine the configuration parameters related to the configuration authorization based on this information, and use the configuration parameters when the terminal device is in multi-subband operating mode. The configuration authorization information may include a temporary identifier for configuring and scheduling the radio network, downlink configuration authorization configuration, and / or uplink configuration authorization configuration. The temporary identifier for configuring and scheduling the radio network is used to identify the authorization scheduling method; the downlink configuration authorization configuration is used to configure downlink transmission using the configuration authorization method; and the uplink configuration authorization configuration is used to configure uplink transmission using the configuration authorization method.

[0071] Configured grant (CG) can support the transmission of the same TB block across multiple time slots, i.e., TBprocessing over multiple slots (TBoMS), which combines CG with multi-time slot transmission. The terminal device can receive a sequence of Redundancy Versions (RVs) used to transmit multiple time slots of the same TB block within a CG period sent by the network device, or the terminal device can determine the RV sequence used to transmit multiple time slots of the same TB block within a CG period based on protocol agreements.

[0072] The RV sequence can be the order in which at least one redundant version of the transport block is sent. The TB is the data delivered from the Medium Access Control (MAC) layer to the physical layer for transmission. The terminal device transmits the TB using multiple slots, with each slot transmitting only a portion of the encoded data from that TB.

[0073] S202, determine at least one starting transmission position of TB transmission from multiple time slots corresponding to the RV sequence.

[0074] Within a semi-static transmission cycle, the RV sequence corresponds to multiple time slots. These time slots can use the same redundant version or different redundant versions, determined based on network device configuration or protocol agreement. For example, the RV sequence could be {RV#0, RV#0, RV#0, RV#0}, or {RV#0, RV#3, RV#0, RV#3}, or {RV#0, RV#2, RV#3, RV#1}, etc. The RV sequence here is merely an example and should not be considered a limitation of this application.

[0075] It should be noted that in scenarios where multiple time slots are used to transmit the same TB (TBoMS), each time slot occupies the same time domain resources, and the frequency domain resources are of equal length, although their locations may be the same or different. Specifically, when frequency hopping is enabled, the frequency domain resource locations differ; when frequency hopping is disabled, the frequency domain resource locations are the same.

[0076] Furthermore, when the terminal device generates data, in order to transmit data in a timely manner and shorten the transmission latency, the terminal device can start data retransmission on a time slot other than the first time slot. The time slot where data transmission can be initiated is called the initial transmission position. In this embodiment, at least one starting transmission position for TB transmission can be determined from multiple time slots corresponding to the RV sequence. In some implementations, the starting transmission position corresponding to TB transmission can be one or multiple; in some implementations, the starting transmission position corresponding to TB transmission can be the first or a non-first; in some implementations, the starting transmission position corresponding to TB transmission can be a time slot included in a specific redundancy version, or a time slot included in each redundancy version. Among these, when there are multiple starting transmission positions corresponding to TB transmission, they can be the first few or the later few.

[0077] This application proposes a method for determining the starting transmission position of a Data Point (TB). In a scenario where a CG (Copyright Controller) is configured to support TBoMS (Transmission By-BoMS) transmission, redundant versions of the Replicated Resource (RV) sequence (RV) for transmitting the same TB within a CG period are determined. From the multiple time slots corresponding to the RV sequence, at least one starting transmission position for the TB transmission is determined. This application embodiment, by determining the starting transmission position of the TB transmission among multiple time slots used to transmit the same TB, enables timely transmission of data generated by the terminal device, shortening data transmission latency and improving data transmission reliability.

[0078] Figure 3 This is a flowchart illustrating a method for determining the starting transmission position of a TB according to an embodiment of this application, executed by a terminal device, such as... Figure 3 As shown, the following steps may be included: S301, determine the redundant version RV sequence used to transmit multiple time slots of the same TB within the CG period.

[0079] The implementation method of step S301 can be adopted from the implementation methods in the various embodiments of this application, and will not be described again here.

[0080] S302, determine the first RV in the RV sequence.

[0081] Based on the RV sequence obtained above, any redundant version is determined as the first RV. For example, version RV#0 in the RV sequence can be used as the first RV. Alternatively, other redundant versions in the RV sequence can also be used as the first RV.

[0082] S303, determine at least one time slot as the starting transmission position from the multiple time slots used for each TB transmission corresponding to the first RV.

[0083] As one feasible approach, at least one time slot can be determined as the starting transmission position from among the multiple time slots used in each TB transmission corresponding to the first RV in the RV sequence. For example, when RV#0 is determined as the first RV, there can be four time slots corresponding to RV#0. The first time slot of the four time slots of RV#0 can be determined as the starting transmission position; or, the first two time slots of the four time slots of RV#0 can be determined as the starting transmission position; or, all four time slots of the four time slots of RV#0 can be determined as the starting transmission position. That is to say, in the CG TBoMS scenario, each slot corresponding to each RV#0 in the RV sequence can be used as the starting transmission time slot.

[0084] As another possible approach, the terminal device can receive indication information sent by the network device and determine a timeslot in the first RV as the starting transmission position based on the indication information. For example, the terminal device can receive indication information sent by the network device, which can directly indicate the timeslot to be used as the starting transmission position. For instance, the indication information can directly indicate that the first timeslot corresponding to the first RV#0 in the RV sequence is the starting transmission position.

[0085] As another possible approach, the terminal device can receive indication information sent by the network device and determine multiple time slots in the first RV to be used as the starting transmission position based on the indication information. For example, the terminal device can receive indication information sent by the network device, which can directly indicate the time slots to be used as the starting transmission position. For instance, the indication information can directly indicate that the first three time slots corresponding to the first RV#0 in the RV sequence are used as the starting transmission position.

[0086] This application embodiment, by determining the starting transmission position, can transmit data generated by the terminal device in a timely manner, shortening data transmission latency and improving data transmission reliability.

[0087] Figure 4 This is a flowchart illustrating a method for determining the starting transmission location of a TB according to an embodiment of this application, executed by a terminal device, such as... Figure 4 As shown, when a time slot is determined as the starting transmission position, determining a starting transmission position for TBoMS from multiple time slots corresponding to the RV sequence may include the following steps: S401, determine the redundant version RV sequence used to transmit multiple time slots of the same TB within the CG period.

[0088] The implementation method of step S401 can be adopted from the implementation methods in the various embodiments of this application, and will not be described in detail here.

[0089] S402, determine the first time slot corresponding to each of the remaining first RVs in the RV sequence (excluding the last first RV) as the starting transmission position, wherein the RV sequence includes only the first RVs.

[0090] For example, the version of RV#0 in the RV sequence can be used as the first RV. In response to the RV sequence consisting only of the first RV, i.e., RV sequence = {RV#0, RV#0, RV#0, RV#0}, where all RVs in the RV sequence are RV#0, the first time slot corresponding to each of the remaining RV#0s, excluding the last RV#0, is determined as the starting transmission position. That is, the terminal device can only initiate transmission on the first time slot corresponding to the first three RV#0s in the RV sequence, and cannot initiate transmission on any of the time slots corresponding to the last RV#0 in the RV sequence. In other words, the first time slot corresponding to each of the remaining first RVs, excluding the last first RV, is determined as the starting transmission position.

[0091] S403, the first time slot corresponding to at least one first RV is determined as the starting transmission position, and the RV sequence includes at least one first RV and at least one other RV.

[0092] For example, version RV#0 in the RV sequence can be used as the first RV. In response to the obtained RV sequence including not only the first RV but also other RVs, the first time slot corresponding to each first RV is determined as the starting transmission position. Here, there can be one or more first RVs.

[0093] As an achievable approach, if the RV sequence = {RV#0, RV#3, RV#0, RV#3}, meaning the RV sequence includes not only multiple first RVs but also other RVs, the terminal device can only initiate transmission on the first time slot corresponding to RV#0, thus determining the first time slot corresponding to RV#0 as the starting transmission position. For example... Figure 5 As shown, the RV sequence = {RV#0, RV#3, RV#0, RV#3}. When data is generated before the second time slot corresponding to the first RV#0, the first time slot corresponding to the second RV#0 is determined as the starting transmission position, and data transmission begins in the first time slot corresponding to the second RV#0.

[0094] As another possible approach, if the RV sequence = {RV#0, RV#2, RV#3, RV#1}, that is, the RV sequence includes not only a first RV but also multiple other RVs, the terminal device can only initiate transmission on the first time slot corresponding to the first RV#0, that is, the first time slot corresponding to the first RV#0 is determined as the starting transmission position.

[0095] In this embodiment, the starting transmission position of TB transmission is determined from multiple time slots corresponding to the RV sequence, which can transmit the data generated by the terminal device in a timely manner, shorten the data transmission latency, and improve the reliability of data transmission.

[0096] Figure 6 This is a flowchart illustrating a method for determining the starting transmission location of a TB according to an embodiment of this application, executed by a terminal device, such as... Figure 6 As shown, the following steps may be included: S601, determine the redundant version RV sequence used to transmit multiple time slots of the same TB within the CG period.

[0097] Regarding step S601, the above embodiments have already provided a detailed description, and will not be repeated here.

[0098] S602, based on the number of time slots occupied by each TB transmission and / or the modulation and coding MCS parameters, determine at least one time slot in the first RV to be used as the starting transmission position.

[0099] As one possible implementation, the scaling factor is determined based on the modulation and coding (MCS) parameters, the scaling factor is determined based on the number of time slots occupied by each TB transmission and the location, and at least one time slot is determined as the starting transmission location.

[0100] Modulation and Coding Scheme (MCS) uses the factors affecting communication rate as columns of a table and the MCS indexes as rows to form a rate table. Each MCS index actually corresponds to the physical transmission rate under a set of parameters.

[0101] Optionally, the MCS parameter can be determined based on network indications or protocol agreements. The location scaling factor can then be determined based on this MCS parameter, where the location scaling factor is denoted as 1 / P. The MCS parameter and the location scaling factor are negatively correlated; that is, the larger the MCS parameter, the smaller the location scaling factor. It should be noted that if the location scaling factor is denoted as P, then the MCS and location scaling factor are positively correlated.

[0102] In some implementations, a threshold is set for the MCS parameter. When the MCS parameter is less than the threshold, the location determination scaling factor is set to a first value; when the MCS parameter is greater than or equal to the threshold, the location determination scaling factor is set to a second value. For example, when determining the starting transmission position based on the formula: 1~N*1 / P timeslots, it should be noted that if there exists a location determination scaling factor of P, since the MCS is positively correlated with P, the first value is less than the second value. If there exists a location determination scaling factor of 1 / P, since the MCS is negatively correlated with 1 / P, the first value is greater than the second value.

[0103] For example, based on the above formula, the position determination scaling factor is P, the threshold is set to k, the first value is set to 4, and the second value is set to 8. When the MCS parameter is less than k, the position determination scaling factor is set to 4; when the MCS parameter is greater than or equal to k, the position determination scaling factor is set to 8.

[0104] In some implementations, a threshold is set for the MCS parameter. When the MCS parameter is less than the set threshold, the position determination scaling factor is set to the first value. When the MCS parameter is greater than or equal to the set threshold, the position determination scaling factor is not activated, and the first time slot corresponding to the first RV is directly used as the starting transmission position. For example, the set threshold can be set to k, and the first value can be set to 4. When the MCS parameter is less than k, the position determination scaling factor is set to 4; when the MCS parameter is greater than or equal to k, the position determination scaling factor is not activated, and the first time slot corresponding to the first RV is directly used as the starting transmission position.

[0105] In some implementations, the mapping relationship between the MCS parameter and the position determination scaling factor can be pre-set. After obtaining the MCS parameter, the mapping relationship can be queried to determine the position determination scaling factor.

[0106] In addition to determining the scaling factor based on the MCS parameters, the scaling factor can also be determined directly based on network indications or protocol conventions. For example, the protocol might specify a scaling factor of 4 for location determination.

[0107] Obtain the number of time slots occupied in each TB transmission and denote this number as N. Determine the scaling factor based on the number of time slots occupied in each TB transmission and its location, and then determine a time slot to be used as the starting transmission position. For example, the starting transmission position can be set to time slots 1 to N*1 / P+1. If the location is determined by the scaling factor P=4, and the number of time slots occupied by TBoMS in one transmission is N=4, the starting transmission position is time slots 1 to 2. If the location is determined by the scaling factor P=4, and the number of time slots occupied by TB in one transmission is N=8, the starting transmission position is time slots 1 to 3. It can be expected that when the scaling factor P is greater than the number of slots N occupied by one TB transmission, the scaling factor is not used, and the first slot corresponding to the first RV is directly used as the starting transmission position.

[0108] This application embodiment determines the scaling factor based on the number of time slots occupied by a TB transmission and the MCS parameter, and determines at least one time slot to be used as the starting transmission position. This enables timely transmission of data generated by the terminal device, shortens data transmission latency, increases transmission redundancy, and improves the reliability of data transmission.

[0109] Figure 7 This is a flowchart illustrating a method for determining the starting transmission position of a TB according to an embodiment of this application, executed by a terminal device, such as... Figure 7 As shown, the following steps may be included: S701, determine the redundant version RV sequence used to transmit multiple time slots of the same TB within the CG cycle.

[0110] S702, determine at least one starting transmission position of TB transmission from multiple time slots corresponding to the RV sequence.

[0111] The implementation methods of steps S701 to S702 can be adopted from the implementation methods in the various embodiments of this application, and will not be repeated here.

[0112] S703, based on the determined starting transmission position, repeatedly transmits TB within the CG cycle.

[0113] In scenarios where the authorized CG supports TBoMS, repeated transmission of TB is also supported. In this embodiment, after determining the starting transmission position of TB, the TB can be repeatedly transmitted multiple times within the CG cycle. For example, if the number of retransmissions is 8, the TB will be repeatedly transmitted 8 times within the CG cycle, and each transmission will start from the determined starting transmission position.

[0114] In this embodiment, the starting transmission position of TB transmission is determined from multiple time slots corresponding to the RV sequence. This allows for timely transmission of data generated by the terminal device, shortening data transmission latency and improving data transmission reliability. Furthermore, based on the repetitive transmission mechanism, the problem of TB loss during transmission can be solved, providing security and integrity for data transmission.

[0115] Figure 8 This is a flowchart illustrating a method for determining the starting transmission position of a TB according to an embodiment of this application, executed by a terminal device, such as... Figure 8 As shown, the method may further include the following steps: S801, determine the redundant version RV sequence used to transmit multiple time slots of the same TB within the CG period.

[0116] S802, determine at least one starting transmission position of TB transmission from multiple time slots corresponding to the RV sequence.

[0117] The implementation methods of steps S801 to S802 can be adopted from the implementation methods in the various embodiments of this application, and will not be repeated here.

[0118] S803, determine the encoded data of the data to be transmitted in each time slot of the first RV.

[0119] For example, if each TB transmission occupies 4 time slots in the first RV, the encoded data of the data to be transmitted is obtained in each time slot of the first RV. That is, the encoded data of the data to be transmitted is allocated to multiple time slots for transmission, that is, each time slot corresponds to a portion of the encoded data of the data to be transmitted.

[0120] S804 starts sending the remaining encoded data to the network device, beginning with the encoded data corresponding to the time slot where the initial transmission position is located.

[0121] Figure 9 This is a diagram illustrating how a terminal device sends encoded data to a network device, such as... Figure 9 As shown, if encoded data is generated in the first time slot of the first RV, the terminal device can start transmission in the second time slot of the first RV. The data transmitted in the second time slot is still the encoded data corresponding to its time slot position. For example, if the encoded data to be transmitted generated by the terminal device in each time slot of the first RV is 12, 34, 56, and 78 respectively, when the terminal device starts transmission in the second time slot of the first RV, it directly transmits 34, 56, and 78 in the time slot order, without transmitting 12 corresponding to the first time slot of the first RV.

[0122] In order to avoid confusion in the data received by network devices and to shorten the data transmission delay, the embodiments of this application increase transmission redundancy and improve the reliability of data transmission.

[0123] Based on the above embodiments, the method for determining the starting transmission location of TB provided in this application embodiment may further include the following steps: The terminal device can also acquire enable signaling, which directly determines the number of time slots used as the starting transmission position in the first RV of the RV sequence. The number of time slots used to determine the starting transmission position can be one or more. For example, the enable signaling can set a 1-bit indicator parameter. When the enable signaling indicates "1", it means that multiple time slots can be used as the starting transmission position; when the enable signaling indicates "0", it means that only one time slot can be used as the starting transmission position.

[0124] Figure 10 This is a flowchart illustrating a method for determining the starting transmission location of a TB according to an embodiment of this application, executed by a network device, such as... Figure 10 As shown, the method may include, but is not limited to, the following steps: S1001, determine the redundant version RV sequence used to transmit multiple time slots of the same TB within the CG cycle.

[0125] In scenarios where CG supports TBoMS transmission, network devices can configure RV sequences for transmitting multiple time slots of the same TB within a CG period, or determine the RV sequences within a CG period based on protocol conventions. The RV sequences can be the order of at least one redundant version of the transmitted transport block. Optionally, after configuring the RV sequences for transmitting multiple time slots of the same TB within a CG period, the network device can send them to the terminal device, enabling the terminal device to determine the starting transmission position of the TB from the multiple time slots corresponding to the RV sequences.

[0126] S1002, determine at least one starting transmission position of TB transmission from multiple time slots corresponding to the RV sequence.

[0127] Within a semi-static transmission cycle, the RV sequence corresponds to multiple time slots. These time slots can use the same redundant version or different redundant versions, determined based on network device configuration or protocol agreement. For example, the RV sequence could be {RV#0, RV#0, RV#0, RV#0}, or {RV#0, RV#3, RV#0, RV#3}, or {RV#0, RV#2, RV#3, RV#1}, etc. The RV sequence here is merely an example and should not be considered a limitation of this application.

[0128] It should be noted that in the time slots used for blind retransmission in TBoMS, each time slot occupies the same time domain resources, and the frequency domain resources are of equal length, although their locations may be the same or different. Specifically, when frequency hopping is enabled, the frequency domain resource locations differ; when frequency hopping is disabled, the frequency domain resource locations are the same.

[0129] Furthermore, network devices need to receive data sent by terminal devices. When a terminal device generates data, in order to transmit the data promptly and shorten the transmission latency, the terminal device can start data retransmission on a time slot other than the first time slot. The time slot where data transmission can be initiated is called the initial transmission position. In this embodiment, at least one starting transmission position for TB transmission can be determined from multiple time slots corresponding to the RV sequence. In some implementations, the starting transmission position corresponding to TB transmission can be one or multiple; in some implementations, the starting transmission position corresponding to TB transmission can be the first or a non-first; in some implementations, the starting transmission position corresponding to TB transmission can be a time slot included in a specific redundancy version, or a time slot included in each redundancy version. When there are multiple starting transmission positions corresponding to TB transmission, they can be the first few or the later few.

[0130] This application proposes a method for determining the starting transmission position of a Time-Based Memory (TB). In scenarios where the Garbage Collection (CG) supports TBoMS transmission, a redundant version RV sequence within the CG period is determined. From multiple time slots corresponding to the RV sequence, at least one starting transmission position for TBoMS is determined. By determining the starting transmission position, this application allows network devices to send or receive data generated by terminal devices in a timely manner, shortening data transmission latency and improving data transmission reliability.

[0131] Figure 11 This is a flowchart illustrating a method for determining the starting transmission location of a TB according to an embodiment of this application, executed by a network device, such as... Figure 11 As shown, the method may include, but is not limited to, the following steps: S1101, determine the redundant version RV sequence used to transmit multiple time slots of the same TB within the CG period.

[0132] The implementation method of step S1101 can be adopted from the implementation methods in the various embodiments of this application, and will not be described again here.

[0133] S1102, determine the first RV in the RV sequence.

[0134] Based on the RV sequence obtained above, any redundant version is determined as the first RV. For example, version RV#0 in the RV sequence can be used as the first RV. Alternatively, other redundant versions in the RV sequence can also be used as the first RV.

[0135] S1103, determine at least one time slot as the starting transmission position from the multiple time slots used for each TB transmission corresponding to the first RV.

[0136] As one feasible approach, at least one time slot can be determined as the starting transmission position from among the multiple time slots used in each TB transmission corresponding to the first RV in the RV sequence. For example, when RV#0 is determined as the first RV, there can be 4 time slots corresponding to RV#0. The first time slot of the 4 time slots of RV#0 can be determined as the starting transmission position; or, the first 2 time slots of the 4 time slots of RV#0 can be determined as the starting transmission position; or, all 4 time slots of the 4 time slots of RV#0 can be determined as the starting transmission position.

[0137] As another possible approach, the network device can send indication information to the terminal device, based on which a timeslot in the first RV is determined as the starting transmission location. For example, the network device can send indication information to the terminal device, which can directly indicate the timeslot to be used as the starting transmission location. For instance, the indication information can directly indicate that the first timeslot corresponding to the first RV#0 in the RV sequence is the starting transmission location.

[0138] As another possible approach, the network device can send indication information to the terminal device, based on which multiple time slots in the first RV can be used as the starting transmission location. For example, the network device can send indication information to the terminal device, which can directly indicate the time slots used as the starting transmission location. For instance, the indication information can directly indicate that the first three time slots corresponding to the first RV#0 in the RV sequence are used as the starting transmission location.

[0139] By determining the starting transmission position, the network device can receive data generated by the terminal device in a timely manner, thereby shortening the data transmission latency and improving the reliability of data transmission.

[0140] Figure 12 This is a flowchart illustrating a method for determining the starting transmission location of a TB according to an embodiment of this application, executed by a network device, such as... Figure 12 As shown, the method may include, but is not limited to, the following steps: S1201, determine the redundant version RV sequence used to transmit multiple time slots of the same TB within the CG cycle.

[0141] The implementation method of step S1201 can be adopted from the implementation methods in the various embodiments of this application, and will not be described in detail here.

[0142] S1202, determine the first time slot corresponding to each of the remaining first RVs in the RV sequence (excluding the last first RV) as the starting transmission position, wherein the RV sequence includes only the first RV.

[0143] For example, the version of RV#0 in the RV sequence can be used as the first RV. In response to the RV sequence consisting only of the first RV, i.e., RV sequence = {RV#0, RV#0, RV#0, RV#0}, where all RVs in the RV sequence are RV#0, the first time slot corresponding to each of the remaining RV#0s, excluding the last RV#0, is determined as the starting transmission position. That is, the network device can receive transmissions initiated by the terminal device on the first time slot corresponding to the first three RV#0s in the RV sequence. The terminal device cannot initiate transmissions on any of the time slots corresponding to the last RV#0 in the RV sequence. In other words, the first time slot corresponding to each of the remaining first RVs, excluding the last first RV, is determined as the starting transmission position.

[0144] S1203, the first time slot corresponding to at least one first RV is determined as the starting transmission position, and the RV sequence includes at least one first RV and at least one other RV.

[0145] For example, version RV#0 in the RV sequence can be used as the first RV. In response to the obtained RV sequence including not only the first RV but also other RVs, the first time slot corresponding to each first RV is determined as the starting transmission position. Here, there can be one or more first RVs.

[0146] As an achievable approach, if the RV sequence = {RV#0, RV#3, RV#0, RV#3}, that is, the RV sequence includes not only multiple first RVs but also other RVs, the network device can receive the terminal device to initiate transmission on the first time slot corresponding to RV#0, that is, determine the first time slot corresponding to RV#0 as the starting transmission position.

[0147] As another possible approach, if the RV sequence = {RV#0, RV#2, RV#3, RV#1}, that is, the RV sequence includes not only a first RV but also multiple other RVs, the network device can receive the terminal device to initiate transmission on the first time slot corresponding to the first RV#0, that is, determine the first time slot corresponding to the first RV#0 as the starting transmission position.

[0148] By determining the starting transmission position, the network device can receive data generated by the terminal device in a timely manner, thereby shortening the data transmission latency and improving the reliability of data transmission.

[0149] Figure 13 This is a flowchart illustrating a method for determining the starting transmission location of a TB according to an embodiment of this application, executed by a network device, such as... Figure 13 As shown, the method may include, but is not limited to, the following steps: S1301, determine the redundant version RV sequence used to transmit multiple time slots of the same TB within the CG cycle.

[0150] The implementation method of step S1301 can be adopted from the implementation methods in the various embodiments of this application, and will not be described in detail here.

[0151] S1302, based on the number of time slots occupied by each TB transmission and / or the modulation and coding MCS parameters, determine at least one time slot in the first RV that is used as the starting transmission position.

[0152] As one possible implementation, the scaling factor is determined based on the modulation and coding (MCS) parameters, the scaling factor is determined based on the number of time slots occupied by a single TBoMS transmission and the location, and at least one time slot is determined as the starting transmission location.

[0153] Modulation and Coding Scheme (MCS) uses the factors affecting communication rate as columns of a table and the MCS indexes as rows to form a rate table. Each MCS index actually corresponds to the physical transmission rate under a set of parameters.

[0154] Optionally, the MCS parameter can be determined based on network indications or protocol agreements. The location scaling factor can then be determined based on this MCS parameter, where the location scaling factor is denoted as 1 / P. The MCS parameter and the location scaling factor are negatively correlated; that is, the larger the MCS parameter, the smaller the location scaling factor. It should be noted that if the location scaling factor is denoted as P, then the MCS and location scaling factor are positively correlated.

[0155] In some implementations, a threshold is set for the MCS parameter. When the MCS parameter is less than the threshold, the location determination scaling factor is set to a first value; when the MCS parameter is greater than or equal to the threshold, the location determination scaling factor is set to a second value. For example, when determining the starting transmission position based on the formula: 1~N*1 / P timeslots, it should be noted that if there exists a location determination scaling factor of P, since the MCS is positively correlated with P, the first value is less than the second value. If there exists a location determination scaling factor of 1 / P, since the MCS is negatively correlated with 1 / P, the first value is greater than the second value.

[0156] For example, based on the above formula, the position determination scaling factor is P, the threshold is set to k, the first value is set to 4, and the second value is set to 8. When the MCS parameter is less than k, the position determination scaling factor is set to 4; when the MCS parameter is greater than or equal to k, the position determination scaling factor is set to 8.

[0157] In some implementations, a threshold is set for the MCS parameter. When the MCS parameter is less than the set threshold, the position determination scaling factor is set to the first value. When the MCS parameter is greater than or equal to the set threshold, the position determination scaling factor is not activated, and the first time slot corresponding to the first RV is directly used as the starting transmission position. For example, the set threshold can be set to k, and the first value can be set to 4. When the MCS parameter is less than k, the position determination scaling factor is set to 4; when the MCS parameter is greater than or equal to k, the position determination scaling factor is not activated, and the first time slot corresponding to the first RV is directly used as the starting transmission position.

[0158] In some implementations, the mapping relationship between the MCS parameter and the position determination scaling factor can be pre-set. After obtaining the MCS parameter, the mapping relationship can be queried to determine the position determination scaling factor.

[0159] In addition to determining the scaling factor based on the MCS parameters, the scaling factor can also be determined directly based on network indications or protocol conventions. For example, the protocol might specify a scaling factor of 4 for location determination.

[0160] Obtain the number of time slots occupied in each TB transmission and denote this number as N. Determine the scaling factor based on the number of time slots occupied in each TB transmission and its location, and then determine a time slot to be used as the starting transmission position. For example, the starting transmission position can be set to time slots 1 to N*1 / P+1. If the location is determined by the scaling factor P=4 and the number of time slots occupied in each TB transmission N=4, the starting transmission position is time slots 1 to 2. If the location is determined by the scaling factor P=4 and the number of time slots occupied in each TB transmission N=8, the starting transmission position is time slots 1 to 3. It can be expected that when the scaling factor P is greater than the number of time slots occupied in one TB transmission N, the scaling factor is not used, and the first time slot corresponding to the first RV is directly used as the starting transmission position.

[0161] This application embodiment determines the scaling factor based on the number of time slots occupied by TBoMS in one transmission and the MCS parameter, and determines at least one time slot to be used as the starting transmission position. The network device can receive the data generated by the terminal device in a timely manner, shortening the data transmission latency and improving the reliability of data transmission.

[0162] Figure 14 This is a flowchart illustrating a method for determining the starting transmission location of a TB according to an embodiment of this application, executed by a network device, such as... Figure 14 As shown, the method may include, but is not limited to, the following steps: S1401, determine the redundant version RV sequence used to transmit multiple time slots of the same TB within the CG period.

[0163] S1402, determine at least one starting transmission position of TB transmission from multiple time slots corresponding to the RV sequence.

[0164] The implementation methods of steps S1401 to S1402 can be adopted from the implementation methods in the various embodiments of this application, and will not be repeated here.

[0165] S1403, receive encoded data corresponding to the starting transmission position at the starting transmission position.

[0166] For example, if TBoMS transmission occupies 4 time slots in the first RV each time, the encoded data of the data to be transmitted generated by the terminal device in each time slot of the first RV is determined.

[0167] If encoded data is generated in the first time slot of the first RV, the network device can receive data transmitted by the terminal device starting in the second time slot of the first RV. The data transmitted in the second time slot is still the encoded data corresponding to its time slot position. For example, if the encoded data to be transmitted generated by the terminal device in each time slot of the first RV is 12, 34, 56, and 78 respectively, when the terminal device starts transmission in the second time slot of the first RV, it directly transmits 34, 56, and 78 in the time slot order, without transmitting 12 corresponding to the first time slot of the first RV. The network device can then receive 34, 56, and 78 transmitted by the terminal device in the time slot order when it starts transmission in the second time slot of the first RV.

[0168] In order to avoid confusion in the data received by the network device, the embodiments of this application enable the network device to receive the data generated by the terminal device in a timely manner, shorten the data transmission latency, increase transmission redundancy, and improve the reliability of data transmission.

[0169] Based on the above embodiments, the method for determining the starting transmission location of TB provided in this application embodiment may further include the following steps: Network devices can also send enable signaling to terminal devices. This enable signaling directly indicates the number of time slots used as the starting transmission position in the first RV of the RV sequence. The number of time slots used to indicate the starting transmission position can be one or more. For example, the enable signaling can set a 1-bit indicator parameter. When the enable signaling indicates "1", it means that multiple time slots can be used as the starting transmission position; when the enable signaling indicates "0", it means that only one time slot can be used as the starting transmission position.

[0170] Figure 15 This is a flowchart illustrating a method for determining the starting transmission position of a TB according to an embodiment of this application, executed by a terminal device, such as... Figure 15 As shown, the method may include, but is not limited to, the following steps: S1501, determine the redundant version RV sequence used to transmit multiple time slots of the same TB within the CG period.

[0171] S1502, determine at least one starting transmission position of TB transmission from multiple time slots corresponding to the RV sequence.

[0172] The implementation methods of steps S1501 to S1502 can be adopted from the implementation methods in the various embodiments of this application, and will not be repeated here.

[0173] S1503, based on the determined starting transmission position, repeatedly transmits TB within the CG cycle.

[0174] In scenarios where the authorized CG supports TBoMS, repeated transmission of TB is also supported. In this embodiment, after determining the starting transmission position of TB, the TB can be repeatedly transmitted multiple times within the CG cycle. For example, if the number of retransmissions is 8, the TB will be repeatedly transmitted 8 times within the CG cycle, and each transmission will start from the determined starting transmission position.

[0175] In this embodiment, the starting transmission position of TB transmission is determined from multiple time slots corresponding to the RV sequence, enabling timely data transmission, shortening data transmission latency, and improving data transmission reliability. Furthermore, based on the repetitive transmission mechanism, the problem of TB loss during transmission can be solved, providing data transmission security and integrity.
