Description

TECHNICAL FIELD

[0001] The present disclosure relates to the field of communication technology, and particularly relates to a transport block size (TBS) configuration method, device and storage medium. BACKGROUND

[0002] In recent years, the Internet of Things has developed rapidly and brought great convenience to people's life and work. Among them, Machine Type Communication (MTC) and Narrow Band Internet of Things (NB-IoT) are typical representatives of cellular Internet of Things technology. Currently, these technologies have been widely used in smart cities (such as meter reading), smart agriculture (such as temperature and humidity information collection), smart transportation (such as shared bicycles), and many other fields.

[0003] When NB-IoT performs communication transmission, the TBS value is determined based on the TBS index (I TBS ) in the TBS table and the resource allocation amount (I SF ) allocated to the TBS. For example, when I TBS is 10 and I SF is 2, the corresponding TBS value is 504. For NB-IoT downlink, QPSK modulation is supported in Release 16 stage. NB-IoT supports Inband working mode. In the Inband working mode, 0≤I TBS ≤10 is limited.

[0004] In order to further improve the transmission rate of NB-IoT, 16QAM and other high-order modulation modes are further introduced in Release 17 stage. For the supported TBS of downlink, the maximum TBS number supported is allowed to be expanded. For uplink transmission, it is required that the number of TBS cannot be increased. Since high-order modulation modes are introduced, the TBS table will also be expanded. However, for high-order modulation modes in Inband working mode, the TBS usage information is not limited.

[0041] The exemplary embodiments will be described in detail herein with reference to the attached drawings. The following description is made with reference to the accompanying drawings in which like reference numerals refer to like elements, unless the context dictates otherwise. The following description of exemplary embodiments is not representative of all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0042] The TBS configuration method provided by the embodiments of the present disclosure can be applied to Figure 1 The wireless communication system shown in FIG. 1. Referring to Figure 1 The wireless communication system shown in FIG. 1. Referring to

[0043] It can be understood that Figure 1 The wireless communication system shown in FIG. 1 is only illustrative, and the wireless communication system can further include other network devices, such as a core network device, a wireless relay device, and a wireless backhaul device, etc., which are not shown in Figure 1 The embodiments of the present disclosure do not limit the number of network devices and the number of terminals included in the wireless communication system.

[0044] It can be further understood that the wireless communication system of the embodiments of the present disclosure is a network that provides wireless communication functions. The wireless communication system can use different communication technologies, such as code division multiple access (CDMA), wideband code division multiple access (WCDMA), time division multiple access (TDMA), frequency division multiple access (FDMA), orthogonal frequency division multiple access (OFDMA), single carrier frequency division multiple access (SC-FDMA), carrier sense multiple access with collision avoidance (CSMA / CA). According to different network capacities, rates, latencies, and other factors, the network can be divided into 2G (English: generation) networks, 3G networks, 4G networks, or future evolution networks, such as 5G networks. The 5G network can also be referred to as a new radio network (New Radio, NR). For convenience of description, the wireless communication network is sometimes referred to as a network in the present disclosure.

[0045] Further, the network device involved in the present disclosure can also be referred to as a wireless access network device. The wireless access network device can be a base station, an evolved node B (eNB), a home base station, an access point (AP) in a wireless fidelity (WiFi) system, a wireless relay node, a wireless backhaul node, a transmission point (TP), a transmission and reception point (TRP), etc., and can also be a gNB in an NR system, or can also be a component or a part of a device constituting a base station, etc. When it is a vehicle-to-everything (V2X) communication system, the network device can also be a vehicle-mounted device. It should be understood that the specific technology and specific device form adopted by the network device in the embodiments of the present disclosure are not limited.

[0046] Further, the terminal involved in the present disclosure can also be referred to as a terminal device, a user equipment (UE), a mobile station (MS), a mobile terminal (MT), etc., and is a device that provides voice and / or data connectivity for a user, for example, a handheld device with a wireless connection function, a vehicle-mounted device, etc. At present, some examples of the terminal are: a mobile phone, a pocket personal computer (PPC), a palm computer, a personal digital assistant (PDA), a notebook computer, a tablet computer, a wearable device, or a vehicle-mounted device, etc. In addition, when it is a vehicle-to-everything (V2X) communication system, the terminal device can also be a vehicle-mounted device. It should be understood that the specific technology and specific device form adopted by the terminal in the embodiments of the present disclosure are not limited.

[0047] The terminal involved in the embodiments of the present disclosure can be understood as a device supporting MTC and NB-IoT. Since the devices supporting MTC and NB-IoT are mostly deployed in basements, and due to the hardware limitations of the devices, the coverage capability thereof is not as good as that of a conventional long term evolution (LTE) terminal. Therefore, repetition transmission is adopted in MTC and NB-IoT to accumulate power, so as to achieve the effect of coverage enhancement. In simple terms, repetition transmission is to transmit the same transmission content in multiple time units. The time unit can be one subframe or multiple subframes.

[0048] In addition, since the MTC and NB-IoT enabled devices are mostly deployed in scenarios where it is not easy to charge or replace the battery, such as in the wild or in the basement, power saving for the MTC and NB-IoT enabled devices is a major feature of the MTC and NB-IoT enabled devices.

[0049] In the related art, when the MTC and NB-IoT enabled devices perform communication transmission, the TBS value is determined based on (I_TBS) in the TBS table and I_SF allocated for the TBS. The downlink TBS table of NB-IoT is shown in Table 1 below.

[0050] Table 1

[0051]

[0052] In Table 1, I_TBS is the TBS index, and I_SF is the resource allocation amount allocated for the TBS. The numbers in Table 1 are the TBS values determined according to the TBS index and the resource allocation amount allocated for the TBS. For example, when I_TBS is 10 and I_SF is 2, the corresponding TBS value is 504. For the downlink of NB-IoT, QPSK modulation is supported in the Release 16 stage.

[0053] The NB-IoT enabled devices support the following four working modes: standalone working mode, i.e., the NB-IoT system works in independent deployment; guard band working mode, i.e., the NB-IoT system works in the guard band of other systems; in-band same physical cell identifier (Inband same PCI) working mode, i.e., coexistence with the LTE system and sharing the PCI-related parameters with the LTE; and in-band different physical cell identifier (Inband different PCI) working mode, i.e., coexistence with the LTE system but using different PCI-related parameters with the LTE.

[0054] The NB-IoT enabled devices select the supported four working modes by indicating the operationModeInfo parameter in the high layer signaling of NB-IoT. When operationModeInfo is set to 00 or 01, respectively, it means that inband same PCI or inband different PCI is currently used. When operationModeInfo indicates 00 or 01, then 0≤I TBS≤ 10, and there is no such limit for other operation modes.

[0055] For devices that introduce 16QAM and other high-order modulation modes and support NB-IoT, there is no restriction on TBS usage information when operation Mode Info indicates 00 or 01.

[0056] Therefore, the present embodiment provides a TBS configuration method, which configures TBS usage information for different types of terminals respectively, and realizes the restriction of TBS usage information for different types of terminals.

[0057] In the present embodiment, any two different types of terminals in different types of terminals are referred to as a first type of terminal and a second type of terminal. The TBS usage information configured for the first type of terminal is referred to as first TBS usage information, and the TBS usage information configured for the second type of terminal is referred to as second TBS usage information.

[0058] It can be understood that the number of terminal types corresponding to the TBS usage information configured in the present embodiment is not limited. For example, in an example, TBS usage information is configured for at least two types of terminals. Of course, the terminal types involved in the present embodiment are not limited to two types. Further, in the present embodiment, each type of the first type of terminal and / or the second type of terminal is not limited to one, but can also be multiple.

[0059] Figure 2 is a flowchart of a TBS configuration method according to an exemplary embodiment, as Figure 2 shown, the TBS configuration method is used in a network device, and includes the following steps.

[0060] In step S11, first TBS usage information and second TBS usage information are configured.

[0061] The first TBS usage information corresponds to the first type of terminal, and the second TBS usage information corresponds to the second type of terminal.

[0062] In the present embodiment, the first TBS usage information is configured for the first type of terminal, and the second TBS usage information is configured for the second type of terminal, so as to meet the differentiated needs of different types of terminals for TBS usage information restriction, and realize the restriction of TBS usage information for different types of terminals.

[0063] It can be understood that the first type of terminal and the second type of terminal in the present embodiment can be terminals that support modulation with different modulation orders.

[0064] In an example, the first type of terminal can be a terminal supporting low order modulation. In an embodiment, the first type of terminal supports a modulation order lower than a first modulation order threshold. The first modulation order threshold can be set according to actual requirements. For example, the first modulation order threshold can be set to 16 in an embodiment of the present disclosure. In an example, the first type of terminal only supports QPSK modulation, and the modulation order is 4, which is lower than 16.

[0065] In another example, the second type of terminal can be a terminal supporting high order modulation. In an embodiment, the second type of terminal supports a maximum modulation order higher than or equal to the first modulation order threshold. The first modulation order threshold can be set according to actual requirements. For example, the first modulation order threshold can be set to 16 in an embodiment of the present disclosure.

[0066] In an embodiment of the present disclosure, the first type of terminal is a terminal not supporting 16QAM high order modulation, and the second type of terminal is a terminal supporting 16QAM high order modulation.

[0067] In an example, when the first TBS usage information of the first type of terminal is configured, the TBS index usage range corresponding to the first type of terminal can be configured. For example, the first type of terminal is a terminal not supporting 16QAM, and the TBS index usage range of the first type of terminal is 0 to 10, i.e., 0≤I TBS ≤10.

[0068] In an embodiment of the present disclosure, when the second type of terminal supports a modulation order higher than or equal to the first modulation order threshold, the second TBS usage information of the second type of terminal can be configured to be different from the first TBS usage information of the first type of terminal, i.e., the first TBS usage information is different from the second TBS usage information.

[0069] In an embodiment, the first TBS usage information and the second TBS usage information can be different, i.e., the TBS index usage range supported by the first type of terminal is different from the TBS index usage range supported by the second type of terminal.

[0070] In an example, the TBS index usage range supported by the first type of terminal can be different from the TBS index usage range supported by the second type of terminal, i.e., the maximum index of the TBS supported by the first type of terminal is different from the maximum index of the TBS supported by the second type of terminal. For example, the maximum index of the TBS supported by the first type of terminal is smaller than the maximum index of the TBS supported by the second type of terminal (the maximum index of the TBS supported by the second type of terminal is greater than the maximum index of the TBS supported by the first type of terminal). For example, the TBS index usage range of the first type of terminal is 0 to 10, and the TBS index usage range of the second type of terminal is 0 to 13.

[0071] In an embodiment, the first TBS usage information and the second TBS usage information can be different in a mapping relationship between a TBS index and a TBS value (a TBS table). In the present disclosure, the TBS table representing the mapping relationship between the TBS index and the TBS value is referred to as a first TBS table for the sake of description. That is, the first TBS table used by the first type of terminal and the second TBS table used by the second type of terminal are different in the present disclosure.

[0072] In an embodiment, the first TBS table used by the first type of terminal and the TBS table used by the second type of terminal can be different in that the maximum TBS value supported by the first type of terminal is different from the maximum TBS value supported by the second type of terminal. For example, the maximum TBS value supported by the first type of terminal is smaller than the maximum TBS value supported by the second type of terminal (the maximum TBS value supported by the second type of terminal is greater than the maximum TBS value supported by the first type of terminal). For example, the maximum TBS used by the first type of terminal is 680 bits, and the maximum TBS supported by the second type of terminal is 1352 bits.

[0073] In an embodiment, the first TBS usage information and the second TBS usage information can be different in a mapping relationship between a TBS index and a modulation and coding scheme (MCS) index. In the present disclosure, the mapping relationship between the TBS index and the MCS index used by the first type of terminal is referred to as a first mapping relationship, and the mapping relationship between the TBS index and the MCS index used by the second type of terminal is referred to as a second mapping relationship. The first mapping relationship used by the first type of terminal and the second mapping relationship used by the second type of terminal are different.

[0074] In an embodiment, the first mapping relationship used by the first type of terminal and the second mapping relationship used by the second type of terminal can be different in that the TBS index used by the first type of terminal is the same as the MCS index, and the TBS index used by the second type of terminal is different from the MCS index.

[0075] In the present disclosure, the mapping relationship between the TBS index and the MCS index is represented by a table for the sake of description. For example, the mapping relationship between the TBS index and the MCS index can be represented by Table 2.

[0076] Table 2

[0077]

[0078] In Table 2, I MCS represents an MCS index, Q m represents a modulation order, I TBS represents a TBS index. Referring to Table 2, I MCS is different from I TBSDifferent. It can be understood that the index value mapped between I MCS and I TBS The index value mapped between I and I is randomly allocated, and the specific index value is not limited by the embodiments of the present disclosure.

[0079] Further, the TBS configuration method provided in the embodiments of the present disclosure can be applied to the TBS information configuration scenario of the terminal supporting NB-IoT. Wherein, when the working mode of the terminal supporting NB-IoT is Inband scenario, the available transmission resources are relatively less, so it is necessary to reduce the use of resource blocks (English full name: Resource Block, English abbreviation: RB). Therefore, it is more suitable to limit the TBS usage information for the terminal working mode as Inband scenario.

[0080] In an embodiment, the TBS configuration method related to the above is implemented for Inband scenario in the embodiments of the present disclosure. That is, the TBS configuration method related to the embodiments of the present disclosure further comprises: determining that the working mode indicated by the working mode indication information is Inband working mode.

[0081] Figure 3 A flow chart of a TBS configuration method according to an exemplary embodiment is shown, as Figure 2 The TBS configuration method is used in a network device, comprising the following steps.

[0082] In step S21, it is determined that the working mode indicated by the working mode indication information is Inband working mode.

[0083] In step S22, the first TBS usage information and the second TBS usage information are configured. Wherein, the first TBS usage information corresponds to the first type terminal, and the second TBS usage information corresponds to the second type terminal.

[0084] In the embodiments of the present disclosure, the Inband working mode can be indicated by the working mode indication information (operation Mode Info) in the NB-IoT system. When the operation Mode Info is indicated as "00" and "01", it corresponds to the Inband deployment scenario, that is, the Inband working mode.

[0085] In the embodiments of the present disclosure, in the Inband deployment scenario, the first TBS usage information and the second TBS usage information are configured. Wherein, the first type terminal uses the first TBS usage information. The second type terminal uses the second TBS usage information.

[0086] The TBS usage information involved in the above embodiments of the present disclosure can also be referred to as a TBS usage rule. That is, for the deployment scenario of Inband, two sets of TBS usage rules (a first TBS usage rule and a second TBS usage rule) are configured. The first type of terminal uses the first TBS usage rule. The second type of terminal uses the second TBS usage rule.

[0087] In the embodiments of the present disclosure, the TBS configuration method involved in the above embodiments can be applied to the scenario of interactive communication between a network device and a terminal.

[0088] When the network device and the terminal interactively communicate, the network device sends TBS indication information to the terminal, and the TBS indication information is used to indicate the first TBS usage information or the second TBS usage information. For the first type of terminal, the network device sends TBS indication information used to indicate the first TBS usage information. For the second type of terminal, the network device sends TBS indication information used to indicate the second TBS usage information.

[0089] When the first type of terminal receives the TBS indication information used to indicate the first TBS usage information, the first type of terminal determines that the TBS usage information is the first TBS usage information, and communicates according to the first TBS usage information.

[0090] When the second type of terminal receives the TBS indication information used to indicate the second TBS usage information, the second type of terminal determines that the TBS usage information is the second TBS usage information, and communicates according to the second TBS usage information.

[0091] In the embodiments of the present disclosure, the first type of terminal communicates according to the first TBS usage information, and the second type of terminal communicates according to the second TBS usage information, so that different TBS usage information is used for different types of terminals, and the differentiated needs of different types of terminals for TBS usage information are met.

[0092] Based on the same concept, the present disclosure also provides a TBS configuration apparatus.

[0093] It can be understood that the TBS configuration apparatus provided by the embodiments of the present disclosure comprises a hardware structure and / or a software module corresponding to the execution of each function in order to realize the above functions. In combination with the units and algorithm steps of each example disclosed in the embodiments of the present disclosure, the embodiments of the present disclosure can be realized in the form of hardware or a combination of hardware and computer software. Whether a certain function is driven by hardware or computer software depends on the specific application and design constraints of the technical solution. Those skilled in the art can use different methods to implement the described functions for each specific application, but such implementation should not be considered beyond the scope of the technical solutions of the embodiments of the present disclosure.

[0096] In an example, the first type of terminal supports a modulation order lower than a first modulation order threshold, and the first TBS usage information includes a TBS index usage range corresponding to the first type of terminal.

[0097] In an example, the second type of terminal supports a modulation order higher than or equal to the first modulation order threshold.

[0098] In an example, the processing unit 101 configures the TBS index usage range supported by the first type of terminal to be different from the TBS index usage range supported by the second type of terminal.

[0099] In an example, the processing unit 101 configures the maximum index of TBS usage supported by the first type of terminal to be smaller than the maximum index of TBS usage supported by the second type of terminal.

[0100] In an example, the processing unit 101 configures a TBS table used by the first type of terminal to be different from a TBS table used by the second type of terminal, wherein the TBS table includes TBS indexes and TBS values.

[0101] In an example, the processing unit 101 configures the maximum TBS value supported by the first type of terminal to be smaller than the maximum TBS value supported by the second type of terminal.

[0102] In an example, the processing unit 101 configures a second mapping relationship used by the first type of terminal to be different from a second mapping relationship used by the second type of terminal, wherein the second mapping relationship represents a corresponding relationship between a TBS index and an MCS index.

[0103] In an example, the processing unit 101 configures the TBS index used by the first type of terminal to be the same as the MCS index, and configures the TBS index used by the second type of terminal to be different from the MCS index.

[0104] In an example, the processing unit 101 is further configured to determine that the working mode indicated by the working mode indication information is a same-frequency band working mode.
