Configuring data transmission on UL SPS resources for BSRs is an optional function for terminals and can be configured via independent capability indication signaling. In NB-IoT, the current protocol specifies a relatively small Transport Block Size (TBS) of only 16 bits for UL SPS resources, thus limiting their data transmission capacity. Summary of the Invention

[0019] Wherein, the TBS determined by the extended scheme is not less than the TBS specified in the protocol.

[0020] Fifthly, embodiments of this application provide a system for improving uplink semi-static scheduling transmission capabilities, comprising:

[0035] This application provides a method, apparatus, and electronic device for improving uplink semi-static scheduling transmission capabilities.

[0036] To enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this application.

[0037] This application relates to data transmission in NB-IoT, where the data transmitting device can be a network device or a terminal, and the data receiving device can be a terminal or a network device. The network device can be a base station in NB-IoT, or a module or unit that performs some of the base station's functions. This application does not limit the specific technology or device form used in the network device. The terminal can also be referred to as a terminal device, user equipment (UE), mobile station, or mobile terminal, and includes, but is not limited to, smart meters, smoke detectors, sensors, shared bicycle locks, logistics tracking tags, wearable health devices, pet trackers, etc. This application also does not limit the specific technology or device form used in the terminal.

[0038] The method and apparatus for improving uplink semi-static scheduling transmission capability provided in this application can be applied to various NB-IoT scenarios, including but not limited to: scenarios where the base station schedules the terminal to send uplink data on the Narrowband Physical Uplink Shared Channel (NPUSCH), or scenarios where the terminal sends uplink data on the NPUSCH according to the scheduling of the base station, etc.

[0039] The above-described method and apparatus, by employing the TBS determined by the extended scheme to transmit uplink data on the NPUSCH, can use a larger TBS to transmit data compared to existing technologies, thereby improving the uplink data transmission capability in NB-IoT.

[0040] This application also relates to extending the existing narrowband downlink control information (DCI) format N0 as specified in the protocol. DCI format N0 is the DCI format used for scheduling NPUSCH in NB-IoT. The existing protocol's DCI Format N0 includes multiple bit fields. The flag bit "Flag for Format N0 / Format N1 Differentiation" identifies whether the current DCI format is DCI Format N0 or DCI Format N1. If the value of this flag bit is 0, it indicates that the DCI type is DCI Format N0; if the value of this flag bit is 1, it indicates that the DCI type is DCI Format N1. In the DCI Format N0 involved in this application embodiment, the value of this flag bit is always 0. The specific functions of the other fields in DCI Format N0 are described in Table 1.

[0041]

[0042] This application extends some fields in DCI format N0, specifically indicating the extension scheme of TBS through the scheduling delay field and the new data indication field. The detailed process is described in the following embodiments.

[0043] like Figure 1 As shown in the figure, this application provides a method for improving uplink semi-static scheduling transmission capability, applied to a terminal, and may include the following steps:

[0044] S102: Receive Narrowband Radio Resource Control (RRC) connection establishment message.

[0045] The terminal first performs a power-on process, including cell search and downlink channel synchronization. Then, it obtains uplink synchronization via random access. After successfully resolving contention, the base station sends the connection state configuration information to the terminal via a Radio Resource Control (RRC) Setup-NB message.

[0046] The NPUSCH dedicated configuration information element in the narrowband RRC connection establishment message includes a first field, which is used to indicate the usage scheme of the UL SPS TBS, including the extension scheme.

[0047] S104: If the first field is a first indication value or a second indication value, the uplink data is sent on the NPUSCH using the TBS determined by the extended scheme.

[0048] The TBS determined by the extended scheme shall not be less than the TBS specified in the protocol.

[0049] The first and second indicator values ​​can be set as needed, and the specific values ​​are not limited. For example, the first indicator value is 0 and the second indicator value is 1; or the first indicator value is 1 and the second indicator value is 0, etc.

[0050] In this application embodiment, the above-mentioned extension scheme includes a first extension scheme and a second extension scheme.

[0051] Accordingly, step S104 above may include:

[0052] When the first field is the first indication value, the uplink data is sent on the NPUSCH using the TBS determined by the first extension scheme;

[0053] When the first field is the second indication value, the uplink data is sent on the NPUSCH using the TBS determined by the second extension scheme.

[0054] For example, the NPUSCH-ConfigDedicated-NB cell in the RRC Setup-NB message carries the first field, sps_tbs_cal_selection. When sps_tbs_cal_selection=0, the terminal uses the TBS determined by the first extension scheme to send uplink data on the NPUSCH. When sps_tbs_cal_selection=1, the terminal uses the TBS determined by the second extension scheme to send uplink data on the NPUSCH.

[0055] In one embodiment of this application, the first expansion scheme includes 7 TBSs, and the second expansion scheme includes the 7 TBSs in the first expansion scheme as well as other TBSs. The smallest TBS in the second expansion scheme is 16 bits, and the largest TBS in the second expansion scheme is 2536 bits.

[0056] For example, the first expansion scheme includes 7 TBSs, with the specific bit counts of these 7 TBSs being {16, 56, 120, 208, 256, 328, 424}. The second expansion scheme includes even more TBSs, ranging from 16 to 2536 bits, including the 7 TBSs from the first expansion scheme, thus supporting all TBSs of the NB-IoT NPUSCH.

[0057] In this embodiment of the application, the above method may further include:

[0058] Receive narrowband downlink control information in DCI format N0.

[0059] In the narrowband DCI format N0, the values ​​of the scheduling delay field and the new data indication field are used to form the TBS index.

[0060] Since the scheduling delay field and the new data indication field are not required when UL SPS is activated, these two fields can be extended to indicate the TBS extension scheme. After the TBS index is formed by combining the values ​​of the scheduling delay field and the new data indication field, the corresponding TBS can be determined using this TBS index.

[0061] In this embodiment of the application, the length of the scheduling delay field is 2 bits and the length of the new data indication field is 1 bit, totaling 3 bits. Therefore, by combining the value of the scheduling delay field and the value of the new data indication field, a total of 8 different values ​​can be obtained, which can be used to indicate different TBSs.

[0062] This method of extending the TBS scheme by utilizing existing fields in DCI format N0 achieves forward compatibility with existing protocols. Furthermore, by combining RRC semi-static configuration with DCI dynamic scheduling, NPUSCH scheduling can be completed efficiently and quickly.

[0063] In this embodiment of the application, when the first field is a first indication value, the above method may further include:

[0064] If the TBS index is one of the preset first, second, third, fourth, fifth, sixth, and seventh values, the TBS in the first expansion scheme is determined by the TBS index.

[0065] For example, the preset first to seventh values ​​are 0 to 6 respectively, and the first extension scheme includes 7 TBSs {16, 56, 120, 208, 256, 328, 424}. After constructing the TBS index sps_tbs_index from the values ​​of the scheduling delay field and the new data indication field, if the TBS index is 0, the corresponding TBS is determined to be 16 bits in the first extension scheme; if the TBS index is 1, the corresponding TBS is determined to be 56 bits in the first extension scheme; if the TBS index is 2, the corresponding TBS is determined to be 120 bits in the first extension scheme; if the TBS index is 3, the corresponding TBS is determined to be 208 bits in the first extension scheme; if the TBS index is 4, the corresponding TBS is determined to be 256 bits in the first extension scheme; if the TBS index is 5, the corresponding TBS is determined to be 328 bits in the first extension scheme; and if the TBS index is 6, the corresponding TBS is determined to be 424 bits in the first extension scheme.

[0066] In this embodiment of the application, the first extension scheme of TBS can be used in scenarios with small UL SPS data traffic and can meet the needs of NB-IoT voice services.

[0067] It should be noted that the terminal can also determine whether to activate or deactivate SPS scheduling based on multiple fields in DCI format N0. These multiple fields include redundancy version, number of HARQ processes, modulation and coding scheme, resource allocation, and Flag for Format N0 / Format N1 Differentiation.

[0068] Specifically, if each field in DCI format N0 meets the configuration shown in Table 2, the terminal can determine that the network device initiates the scheduling to activate SPS.

[0069]

[0070] If DCI format N0 meets the configuration shown in Table 3, the terminal can determine that the network device initiates the scheduling to deactivate SPS.

[0071]

[0072] In this embodiment of the application, when the first field is a second indicator value, the above method may further include:

[0073] The TBS in the second extended scheme is determined by the values ​​of the modulation and coding scheme field and the resource allocation field in the narrowband DCI format N0.

[0074] The determination of the corresponding TBS based on the values ​​of the modulation and coding scheme domain and the resource allocation domain can be achieved using methods specified in existing protocols, which will not be elaborated upon here.

[0075] In this embodiment, the second extension scheme of TBS uses the modulation and coding scheme domain and the resource allocation domain to determine the corresponding TBS, which can support all TBS of NPUSCH, from 16 to 2536, meet the needs of NB-IoT voice services, and greatly improve the uplink data transmission capability.

[0076] In this embodiment of the application, when the first field is a second indicator value, the above method may further include:

[0077] If the TBS index is the preset eighth value, the value of the redundant version field in the narrowband DCI format N0 and the value of the Hybrid Automatic Repeat Request (HARQ) process number field are used to determine whether the narrowband DCI format N0 indicates activation or deactivation of SPS.

[0078] In one implementation, determining whether the narrowband DCI format N0 indicates the activation or deactivation of SPS based on the value of the redundant version field and the value of the HARQ process number field in the narrowband DCI format N0 may include:

[0079] If the values ​​of the redundant version field and the HARQ process number field in the narrowband DCI format N0 are both 0, it is determined that the narrowband DCI format N0 indicates the activation of SPS.

[0080] If the values ​​of the redundant version field and the HARQ process number field in the narrowband DCI format N0 are both 1, then the narrowband DCI format N0 indicates that the SPS should be deactivated.

[0081] For example, if DCI Format N0 meets the configuration shown in Table 4, the value of the redundancy version field is 0, and the value of the HARQ process number field is also 0, then the terminal can determine that DCI Format N0 indicates the activation of SPS. In Table 4, the value of the scheduling delay field is binary 11, and the value of the new data indication field is binary 1. The two together form the TBS index, which is binary 111, corresponding to decimal 7, i.e., the preset eighth value.

[0082]

[0083] For example, if DCI Format N0 meets the configuration shown in Table 5, the value of the redundancy version field is 1, and the value of the HARQ process number field is also 1, then the terminal can determine that DCI Format N0 indicates the deactivation of SPS. In Table 5, the value of the scheduling delay field is binary 11, and the value of the new data indication field is binary 1. The two together form the TBS index, which is binary 111, corresponding to decimal 7, i.e., the preset eighth value.

[0084]

[0085] In this embodiment of the application, the above method may further include:

[0086] When SPS is activated, the extended SPS period is obtained from the RRC signaling. The extended SPS period is shorter than the SPS period specified in the protocol.

[0087] In particular, multiple extended SPS cycles, such as {sf16, sf32, sf64}, can be added to the RRC signaling. Compared with the shortest cycle of 128ms in the existing technology, the SPS cycle becomes shorter, such as 16ms, which can achieve faster UL SPS scheduling.

[0088] The method provided in this application embodiment receives a narrowband RRC connection establishment message. The first field in the NPUSCH dedicated configuration cell of the narrowband RRC connection establishment message indicates the usage scheme of the UL SPS's TBS. This usage scheme includes an extended scheme. When the first field is a first indication value or a second indication value, uplink data is transmitted on the NPUSCH using the TBS determined by the extended scheme. The TBS determined by the extended scheme is not less than the TBS specified in the protocol; therefore, a larger TBS can be used to transmit data, improving the uplink data transmission capability in NB-IoT. Furthermore, extending the SPS period to a shorter duration enables faster UL SPS scheduling, thereby meeting more NB-IoT service requirements, such as the need for communication using NTN.

[0089] like Figure 2As shown in the figure, this application provides another method for improving uplink semi-static scheduling transmission capability, applied to network devices, which may include the following steps:

[0090] S202: Send a narrowband RRC connection establishment message. The NPUSCH dedicated configuration cell in the narrowband RRC connection establishment message includes a first field, which is used to indicate the usage scheme of the UL SPS TBS, including the extension scheme.

[0091] Wherein, if the first field is a first indication value or a second indication value, it is used to instruct the terminal to send uplink data on the NPUSCH using the TBS determined by the extended scheme. The TBS determined by the extended scheme is not less than the TBS specified in the protocol.

[0092] In this embodiment of the application, the above-mentioned extension scheme includes a first extension scheme and a second extension scheme. Accordingly, when the first field is a first indication value, it is used to instruct the terminal to send uplink data on the NPUSCH using the TBS determined by the first extension scheme; when the first field is a second indication value, it is used to instruct the terminal to send uplink data on the NPUSCH using the TBS determined by the second extension scheme.

[0093] The first and second indicator values ​​can be set as needed, and the specific values ​​are not limited. For example, the first indicator value is 0 and the second indicator value is 1; or the first indicator value is 1 and the second indicator value is 0, etc.

[0094] For example, a first field, `sps_tbs_cal_selection`, is added to the `NPUSCH-ConfigDedicated-NB` cell of the `RRC Setup` message. When `sps_tbs_cal_selection=0`, it instructs the terminal to use the TBS determined by the first extension scheme to send uplink data on the NPUSCH, supporting up to 6 TBSs. When `sps_tbs_cal_selection=1`, it instructs the terminal to use the TBS determined by the second extension scheme to send uplink data on the NPUSCH, supporting all TBSs of the NB-IoT NPUSCH.

[0095] In this embodiment of the application, the above method may further include:

[0096] The terminal transmits a narrowband DCI format N0, where the values ​​of the scheduling delay field and the new data indication field in the narrowband DCI format N0 are used to form a TBS index. The terminal can determine the corresponding TBS based on this TBS index.

[0097] In this embodiment of the application, when the first field is a first indication value, if the TBS index is one of the preset first, second, third, fourth, fifth, sixth, and seventh values, the terminal is instructed to determine the TBS in the first extension scheme by the TBS index.

[0098] In this embodiment of the application, when the first field is the second indication value, the values ​​of the modulation and coding scheme field and the resource allocation field in the narrowband DCI format N0 are used to instruct the terminal to determine the TBS in the second extended scheme based on the values ​​of the modulation and coding scheme field and the resource allocation field.

[0099] In this embodiment of the application, when the value of the first field is the second indication value and the TBS index is the preset eighth value, the value of the redundant version field and the value of the HARQ process number field in the narrowband DCI format N0 are used to indicate the activation or deactivation of SPS.

[0100] In this embodiment of the application, when the value of the first field is the second indicator value and the TBS index is the preset eighth value, the narrowband DCI format N0 can satisfy one of the following:

[0101] The values ​​of the Redundancy Version field and the HARQ Process Count field are both 0, indicating that SPS is activated;

[0102] The values ​​of the redundant version field and the HARQ process number field are both 1, indicating that SPS should be deactivated.

[0103] In this embodiment, the first expansion scheme includes 7 TBSs, which are 16 bits, 56 bits, 120 bits, 208 bits, 256 bits, 328 bits, and 424 bits. The second expansion scheme includes the 7 TBSs in the first expansion scheme and other TBSs. The smallest TBS in the second expansion scheme is 16 bits, and the largest TBS in the second expansion scheme is 2536 bits.

[0104] In this embodiment of the application, the above method may further include the following steps:

[0105] When the amount of business data is less than the threshold, set the value of the first field to the first indicator value;

[0106] If the amount of business data is greater than or equal to the threshold, set the value of the first field to the second indicator value.

[0107] The thresholds mentioned above can be preset as needed, and the specific values ​​are not limited.

[0108] In this embodiment of the application, the above method may further include:

[0109] In the RRC signaling, an extended SPS period is set, which is shorter than the SPS period specified in the protocol.

[0110] In particular, multiple extended SPS cycles, such as {sf16, sf32, sf64}, can be added to the RRC signaling. Compared with the shortest cycle of 128ms in the existing technology, the SPS cycle becomes shorter, such as 16ms, which can achieve faster UL SPS scheduling.

[0111] The method provided in this application embodiment sends a narrowband RRC connection establishment message. The NPUSCH dedicated configuration information element in the narrowband RRC connection establishment message includes a first field. This first field indicates the TBS usage scheme of the UL SPS. This usage scheme includes an extended scheme. When the first field is a first indication value or a second indication value, it instructs the terminal to use the TBS determined by the extended scheme to send uplink data on the NPUSCH. The TBS determined by the extended scheme is not less than the TBS specified in the protocol, thus allowing the use of a larger TBS to transmit data, improving the uplink data transmission capability in NB-IoT. Furthermore, extending the SPS period to a shorter duration enables faster UL SPS scheduling, thereby meeting more NB-IoT service requirements, such as the need for communication using NTN.

[0112] The above describes a method for improving uplink semi-static scheduling transmission capability provided by embodiments of this application. Based on the same idea, embodiments of this application also provide an apparatus for improving uplink semi-static scheduling transmission capability, such as... Figure 3 As shown, the device, applied to terminal 300, may include:

[0113] The receiving module 301 is used to receive a narrowband RRC connection establishment message. The NPUSCH dedicated configuration information cell in the narrowband RRC connection establishment message includes a first field, which is used to indicate the usage scheme of the UL SPS TBS, including the extended scheme.

[0114] The sending module 302 is used to send uplink data on NPUSCH using the TBS determined by the extended scheme when the first field is a first indication value or a second indication value.

[0115] The TBS determined by the extended scheme shall not be less than the TBS specified in the protocol.

[0116] In this embodiment, the first extension scheme configures 7 TBSs for transmitting uplink data on the NPUSCH. The second extension scheme configures the TBS specified in the protocol, as well as 7 TBSs, for transmitting uplink data on the NPUSCH. The 7 TBSs include extended TBSs.

[0117] In this embodiment, the above-mentioned extension scheme includes a first extension scheme and a second extension scheme. Accordingly, the sending module 302 is specifically used for:

[0118] When the first field is the first indication value, the uplink data is sent on the NPUSCH using the TBS determined by the first extension scheme;

[0119] When the first field is the second indication value, the uplink data is sent on the NPUSCH using the TBS determined by the second extension scheme.

[0120] In this embodiment of the application, the receiving module 301 is further configured to: receive narrowband downlink control information DCI format N0, wherein the value of the scheduling delay field and the value of the new data indication field in the narrowband DCI format N0 are used to form a TBS index.

[0121] In this embodiment of the application, the above-described apparatus is further used for:

[0122] If the TBS index is one of the preset first, second, third, fourth, fifth, sixth, and seventh values, the TBS in the first expansion scheme is determined by the TBS index.

[0123] In this embodiment of the application, the above-described apparatus is further used for:

[0124] When the first field is the second indication value, the TBS in the second extended scheme is determined by the value of the modulation and coding scheme field and the value of the resource allocation field in the narrowband DCI format N0.

[0125] In this embodiment of the application, when the first field is a second indication value, the above-described apparatus is further used to:

[0126] If the TBS index is the preset eighth value, the value of the redundant version field in the narrowband DCI format N0 and the value of the HARQ process number field are used to determine whether the narrowband DCI format N0 indicates activation or deactivation of SPS.

[0127] The value of the redundant version field and the value of the HARQ process number field in the narrowband DCI format N0, as described above, determine whether the narrowband DCI format N0 indicates activation or deactivation of SPS, including:

[0128] If the values ​​of the redundant version field and the HARQ process number field in the narrowband DCI format N0 are both 0, then the narrowband DCI format N0 indicates the activation of semi-persistent scheduling (SPS).

[0129] If the values ​​of the redundant version field and the HARQ process number field in the narrowband DCI format N0 are both 1, then the narrowband DCI format N0 indicates that the SPS should be deactivated.

[0130] In this embodiment, the first expansion scheme includes seven TBSs, which are 16 bits, 56 bits, 120 bits, 208 bits, 256 bits, 328 bits, and 424 bits. The second expansion scheme includes the seven TBSs of the first expansion scheme and other TBSs. The smallest TBS in the second expansion scheme is 16 bits, and the largest TBS in the second expansion scheme is 2536 bits.
