Description

[0001] Divisional application statement

[0002] This application is a divisional application based on the Chinese invention patent application with application number 202080004131.0, application date December 26, 2020, and invention name "Information transmission method and device, storage medium". Technical Field

[0003] The present disclosure relates to the field of communications, and in particular to an information transmission method and device, and a storage medium. Background Art

[0004] In data scheduling, to ensure scheduling flexibility, one DCI (Downlink Control Information) will only schedule one PDSCH (Physical Downlink Shared Channel) or one PUSCH (Physical Uplink Shared Channel).

[0005] In NR (New Radio) systems, multi-TTI scheduling is proposed. This allows a single DCI to schedule multiple PDSCH slots (or PUSCH slots) in multiple time slots, thereby reducing the number of DCIs and lowering the complexity of UE blind DCI detection. Multi-TTI-scheduled PDSCH or PUSCH can be used for repeated data transmission or to transmit different downlink data. Summary of the Invention

[0120] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, when referring to the drawings, like numbers in different figures represent like or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0121] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0122] It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, the word "if" as used herein may be interpreted as "at the time of" or "when" or "in response to determining."

[0123] Currently, multi-TTI scheduling scenarios such as Figure 1 As shown in FIG, one DCI can schedule four PDSCHs, which belong to different slots. Figure 1 The example shows a case where the slots where the four PDSCHs are located are adjacent. It should be noted that the case where the slots where the PDSCHs are located are not adjacent is not excluded, for example, there are two or more slots between every two PDSCHs.

[0124] Figure 1 In the example above, scheduling multiple PDSCHs through one DCI is used. In actual applications, scheduling multiple PUSCHs through one DCI also falls within the scope of multi-TTI scheduling.

[0125] When multi-TTI scheduling is used to schedule multiple identical TBs (Transport Blocks), enhanced coverage can be achieved, which can be used for both uplink and downlink transmissions. In the case where multi-TTI scheduling is used to schedule multiple identical TBs, multiple scheduled PDSCHs or PUSCHs can use the same HARQ (Hybrid Automatic Repeat reQuest) identifier. Taking scheduling multiple PDSCHs as an example, the terminal can combine the demodulation and feedback a single HARQ information.

[0126] When multi-TTI scheduling is used to schedule multiple different TBs, it can be used to reduce the number of DCIs and lower the complexity of terminal blind detection. Since the MCS (Modulation Coding Scheme) used by the PDSCH or PUSCH scheduled in multiple TTIs is usually the same, the number of TTIs scheduled at one time is also related to the speed of channel changes. If the channel changes quickly, then to ensure that the MCS matches the channel, the number of TTIs scheduled at one time will be smaller, and only one TTI can be scheduled. If the channel changes slowly, then the number of TTIs that can be scheduled can be larger.

[0127] In the case where multi-TTI scheduling is used to schedule multiple different TBs, each scheduled PDSCH or PUSCH will have a different HARQ identifier. Taking scheduling multiple PDSCHs as an example, the terminal needs to feedback the HARQ information of each PDSCH.

[0128] In order to enable the terminal to distinguish whether a certain DCI schedules multiple identical TBs or multiple different TBs in multi-TTI scheduling, the present disclosure provides the following information transmission method.

[0129] The following first introduces the information transmission method provided by the embodiment of the present disclosure from the base station side.

[0130] The present disclosure provides an information transmission method that can be used in a base station. Figure 2 As shown, Figure 2 The following is a flow chart of an information transmission method according to an embodiment. The method may include the following steps:

[0131] In step 201, in response to performing multi-transmission time interval (TTI) scheduling through target downlink control information (DCI), first indication information for indicating a target scheduling mode corresponding to the target DCI is sent.

[0132] In an embodiment of the present disclosure, the target DCI is a DCI for multi-TTI scheduling, through which PDSCH or PUSCH of multiple slots can be scheduled. The target scheduling mode includes a first multi-TTI scheduling mode for scheduling two or more identical transport blocks, or the target scheduling mode includes a second multi-TTI scheduling mode for scheduling two or more different transport blocks.

[0133] In the above embodiment, the base station may send first indication information when performing multi-TTI scheduling through the target DCI, so that the terminal can determine the target scheduling mode corresponding to the target DCI. The target scheduling mode may include a first multi-TTI scheduling mode for scheduling two or more identical transport blocks, and the target scheduling mode may also include a second multi-TTI scheduling mode for scheduling two or more different transport blocks. In multi-TTI scheduling, the purpose of scheduling multiple identical or different transport blocks through the target DCI is achieved, thereby improving the flexibility of multi-TTI scheduling.

[0134] In some optional embodiments, reference Figure 3 As shown, Figure 3 FIG. 1 is a flow chart of another information transmission method according to an embodiment. The method may include the following steps:

[0135] In step 301, the target DCI is determined, where the target DCI at least includes a first information field for indicating the target scheduling mode.

[0136] In the embodiment of the present disclosure, the target DCI for performing multi-TTI scheduling may include at least a first information field, which may be an information field for indicating a target scheduling mode corresponding to the target DCI. In the embodiment of the present disclosure, step 301 may be applied to a scenario where multi-transmission time interval (TTI) scheduling is performed using target downlink control information (DCI), or any other appropriate scenario.

[0137] In one example, the first information field may occupy one bit. When the bit value of the first information field is a first preset value, it is used to indicate that the target scheduling mode is the first multi-TTI scheduling mode. When the bit value of the first information field is a second preset value, it is used to indicate that the target scheduling mode is the second multi-TTI scheduling mode. The second preset value is different from the first preset value.

[0138] For example, if the bit value of the first information field is set to 0, it indicates that the target scheduling mode is the first multi-TTI scheduling mode, that is, the target DCI schedules the same multiple TBs. If the bit value of the first information field is set to 1, it indicates that the target scheduling mode is the second multi-TTI scheduling mode, that is, the target DCI schedules different multiple TBs. And vice versa.

[0139] In step 302, the target DCI including the first information field is sent.

[0140] In an embodiment of the present disclosure, the base station may send a target DCI including a first information field, and the terminal may determine a target scheduling mode corresponding to the target DCI according to an indication of the first information field.

[0141] In the above embodiment, the base station can generate a target DCI including a first information field for indicating the target scheduling method, so that the terminal can determine the target scheduling method corresponding to the target DCI according to the indication of the first information field, thereby improving the flexibility of multi-TTI scheduling while saving signaling resources.

[0142] In some optional embodiments, reference Figure 4 As shown, Figure 4 FIG. 1 is a flow chart of another information transmission method according to an embodiment. The method may include the following steps:

[0143] In step 401, a target RNTI corresponding to the target scheduling mode is determined according to the correspondence between different radio network temporary identifiers RNTIs and different scheduling mode indication information.

[0144] In the embodiment of the present disclosure, the above step 401 can be applied to a scenario where multiple transmission time intervals (TTIs) are scheduled using target downlink control information (DCI), or any other appropriate scenario. In one example, RNTI-1 corresponds to the first scheduling mode indication information, and RNTI-2 corresponds to the second scheduling mode indication information. The first scheduling mode indication information is used to indicate the first multi-TTI scheduling mode, and the second scheduling mode indication information is used to indicate the second multi-TTI scheduling mode. The base station can determine the corresponding target RNTI based on the target scheduling mode.

[0145] In step 402, the target DCI is scrambled using the target RNTI.

[0146] In step 403, the target DCI scrambled by the target RNTI is sent.

[0147] In an embodiment of the present disclosure, the base station may send a target DCI scrambled by the target RNTI, and the terminal may determine a target scheduling mode corresponding to the target RNTI after descrambling the target RNTI.

[0148] In the above embodiment, the base station can scramble the target DCI through different RNTIs, allowing the terminal to determine the target scheduling mode corresponding to the target DCI through the target RNTI of the scrambled target DCI, thereby improving the flexibility of multi-TTI scheduling and saving signaling resources.

[0149] In some optional embodiments, reference Figure 5 As shown, Figure 5 FIG. 1 is a flow chart of another information transmission method according to an embodiment. The method may include the following steps:

[0150] In step 501, first signaling for configuring support for the first multi-TTI scheduling mode and the second multi-TTI scheduling mode is sent.

[0151] In the embodiment of the present disclosure, the above step 501 may be applied to a scenario where multiple transmission time intervals (TTIs) are scheduled through target downlink control information (DCI), or any other appropriate scenario.

[0152] In the disclosed embodiment, the base station needs to support the first multi-TTI scheduling mode and the second multi-TTI scheduling mode. Accordingly, the terminal side also needs to support these two scheduling modes. The base station can configure the terminal to support the above two scheduling modes through the first information. The first signaling includes but is not limited to high-layer signaling, and the high-layer signaling may include but is not limited to RRC (Radio Resource Control) signaling and MAC (Media Access Control Address) signaling.

[0153] In the above embodiment, the base station can configure the terminal to support the first multi-TTI scheduling mode and the second multi-TTI scheduling mode through the first signaling. On the basis of the terminal supporting the above two scheduling modes, the target DCI can be used to schedule multiple TBs that are the same or different, thereby improving the flexibility of multi-TTI scheduling.

[0154] In some optional embodiments, reference Figure 6 As shown, Figure 6 FIG. 1 is a flow chart of another information transmission method according to an embodiment. The method may include the following steps:

[0155] In step 601, in response to the target scheduling mode including the second multi-TTI scheduling mode, second indication information for indicating the target number of TTIs scheduled by the target DCI is sent.

[0156] In an embodiment of the present disclosure, the base station can determine that the target scheduling method includes a second multi-TTI scheduling method, that is, when the target DCI schedules multiple different TBs, it sends a second indication information, and the terminal can determine the target number of TTIs where the different TBs scheduled by the target DCI are located based on the second indication information.

[0157] In the above embodiment, the base station may send the second indication information when determining that the target scheduling mode includes the second multi-TTI scheduling mode. The terminal may determine the target number of TTIs for the target DCI scheduling based on the second indication information so that the terminal can subsequently perform HARQ feedback. This improves the flexibility of multi-TTI scheduling.

[0158] In some optional embodiments, reference Figure 7 As shown, Figure 7 FIG. 1 is a flow chart of another information transmission method according to an embodiment. The method may include the following steps:

[0159] In step 701, a second signaling indicating the target number is sent.

[0160] In the embodiment of the present disclosure, the second signaling includes but is not limited to high-layer signaling, and the high-layer information includes but is not limited to RRC signaling and MAC signaling.

[0161] In the above embodiment, the base station can directly send the target number of TTIs scheduled by the target DCI through the second signaling, which is simple to implement and has high availability.

[0162] In some optional embodiments, reference Figure 8 As shown, Figure 8 FIG. 1 is a flow chart of another information transmission method according to an embodiment. The method may include the following steps:

[0163] In step 801, the target DCI is determined, where the target DCI includes at least a second information field for indicating a target number of TTIs scheduled by the target DCI.

[0164] In the embodiment of the present disclosure, the second information field may be an information field for indicating a target number of TTIs scheduled by the target DCI.

[0165] In step 802, the target DCI including the second information field is sent.

[0166] In the above embodiment, the base station may send a target DCI including the second information field when the target scheduling mode includes the second multi-TTI scheduling mode, and the terminal may determine the target number of TTIs scheduled by the target DCI based on the second information field, thereby improving the flexibility of multi-TTI scheduling.

[0167] In some optional embodiments, the base station may directly determine the bit value of the second information field added to the target DCI based on the target number of TTIs scheduled by the target DCI. Optionally, the bit value of the second information field may be set to a value corresponding to the target number.

[0168] For example, the number of TTIs scheduled by the target DCI is 4, and the bit value of the second information field may be 100.

[0169] In the above embodiment, the base station can directly determine the bit value of the second information field based on the target number, which is simple to implement and has high availability.

[0170] In some optional embodiments, the correspondence between different values ​​and different scheduling entry information can be fixed through predefined settings, such as protocol agreements. The scheduling entry information refers to at least one item of information related to scheduling, and each piece of scheduling entry information includes at least the number of TTIs scheduled for multi-TTI scheduling. Of course, each piece of scheduling entry information may also include other scheduling-related information, which is not limited in this disclosure.

[0171] Optionally, the correspondence between different values ​​and different scheduling entry information may be represented by a table, such as shown in Table 1.

[0172] Table 1

[0173]

[0174] In Table 1, the number of TTIs may be a positive integer. Table 1 is merely an example, and those skilled in the art will appreciate that each item of scheduling entry information in Table 1 may be independently used as content agreed upon in the protocol.

[0175] The base station may determine target scheduling entry information including the target number of TTIs scheduled by the target DCI according to Table 1. Further, the base station may determine a target value corresponding to the target scheduling entry information according to Table 1. Thus, the bit value of the second information field is determined based on the target value.

[0176] For example, if the target number is 4, the number of TTIs included in the scheduling entry information 2 in Table 1 is 4, and the value corresponding to the scheduling entry information 2 is 2, then the bit value of the second information field may be set to 10.

[0177] In the above embodiment, the base station may indicate the target scheduling entry information through the second information field, and the terminal may use the number of TTIs included in the target scheduling entry information as the target number, thereby reducing the length of the second information field in the DCI and improving availability.

[0178] In some optional embodiments, reference Figure 9 As shown, Figure 9FIG. 1 is a flow chart of another information transmission method according to an embodiment. The method may include the following steps:

[0195] In the above embodiment, the terminal directly determines the target scheduling mode corresponding to the target DCI according to the first information field in the target DCI for indicating the target scheduling mode, thereby improving the flexibility of multi-TTI scheduling.

[0196] In some optional embodiments, reference Figure 13 As shown, Figure 13 The following is a flow chart of an information transmission method according to an embodiment. The method may include the following steps:

[0197] In step 1301, target scheduling mode indication information corresponding to the target RNTI for scrambling the target DCI is determined according to the correspondence between different radio network temporary identifiers RNTI and different scheduling mode indication information.

[0198] In the embodiment of the present disclosure, the terminal may predetermine the correspondence between different radio network temporary identifiers RNTIs and different scheduling mode indication information, and determine the target scheduling mode indication information corresponding to the target RNTI of the scrambled target DCI.

[0199] In step 1302, the target scheduling mode is determined based on the target scheduling mode indication information.

[0200] In the above embodiment, the terminal can determine the target scheduling mode corresponding to the target DCI by scrambling the target RNTI of the target DCI, thereby improving the flexibility of multi-TTI scheduling while saving DCI signaling resources and having high availability.

[0201] In some optional embodiments, reference Figure 14 As shown, Figure 14 The following is a flow chart of an information transmission method according to an embodiment. The method may include the following steps:

[0202] In step 1401, based on the first signaling sent by the base station, configuration is performed to support the first multi-TTI scheduling mode and the second multi-TTI scheduling mode.

[0203] In the embodiment of the present disclosure, the terminal can configure itself to support the first multi-TTI scheduling mode and the second multi-TTI scheduling mode according to the first signaling sent by the base station. The terminal can then determine whether the target scheduling mode corresponding to the target DCI is one of the above two modes according to the target DCI.

[0204] In the above embodiment, the terminal can be configured to support the first multi-TTI scheduling mode and the second multi-TTI scheduling mode according to the signaling instruction of the base station, thereby improving the flexibility of multi-TTI scheduling.

[0205] In some optional embodiments, reference Figure 15 As shown, Figure 15 The following is a flow chart of an information transmission method according to an embodiment. The method may include the following steps:

[0206] In step 1501, in response to the target scheduling mode including the second multi-TTI scheduling mode, a target number of TTIs of the target DCI scheduling is determined.

[0207] In an embodiment of the present disclosure, when determining that the target scheduling mode includes the second multi-TTI scheduling mode, the terminal may determine the target number of TTIs scheduled by the target DCI, so as to subsequently perform HARQ feedback for each TTI.

[0208] In the above embodiment, the terminal can determine the target number of TTIs scheduled by the target DCI in response to the situation where the base station schedules multiple different TBs through the target DCI, and the availability is high.

[0209] In some optional embodiments, the terminal can directly determine the target number of TTIs scheduled by the target DCI based on the second signaling sent by the base station, where the second signaling includes but is not limited to high-layer signaling, and the high-layer signaling includes but is not limited to RRC signaling and MAC signaling.

[0210] In the above embodiment, when the target scheduling mode includes the second multi-TTI scheduling mode, the terminal can determine the target number of TTIs scheduled by the target DCI according to the instruction of the second signaling sent by the base station, which is simple to implement and has high availability.

[0211] In some optional embodiments, the terminal may determine the target number according to the second information field in the target DCI.

[0212] In one example, the terminal directly uses the number indicated by the bit value of the second information field as the target number.

[0213] For example, the bit value of the second information field is 100, and the number indicated is 4, then the terminal determines that the target DCI schedules multiple different TBs, and the number of scheduled TTIs is 4.

[0214] In another example, the terminal may determine the target number according to the target value indicated by the bit value of the second information field and the correspondence between different values ​​and different scheduling entry information.

[0215] In the embodiment of the present disclosure, the protocol solidifies the correspondence between the above different numerical values ​​and different scheduling entry information. Optionally, the correspondence between different numerical values ​​and different scheduling entry information can be represented by Table 1.

[0216] The terminal determines that the bit value of the second information field is 10, and the indicated target value is 2. Through Table 1, it can be determined that the value 2 corresponds to scheduling entry information 2, and the number of TTIs included in the scheduling entry information 2 is 4. Then the terminal can determine that the number of TTIs scheduled by the target DCI is 4. In the above embodiment, when the target scheduling mode includes the second multi-TTI scheduling mode, the terminal can determine the number of TTIs scheduled by the target DCI through the correspondence between different values ​​and different scheduling entry information, as well as the value indicated by the second information field in the target DCI. While improving the flexibility of multi-TTI scheduling, the target number can be determined by using fewer bit values ​​in the second information field in the target DCI, saving signaling resources.

[0217] In some optional embodiments, reference Figure 16 As shown, Figure 16 The following is a flow chart of an information transmission method according to an embodiment. The method may include the following steps:

[0218] In step 1601, based on the third signaling sent by the base station, it is determined that the target DCI includes the second information field.

The terminal determines, based on the third signaling, that the target DCI includes the second information field. Further, the terminal can determine, based on the second information field, the target number of TTIs scheduled by the target DCI.

[0220] In the above embodiment, when the target scheduling mode includes a second multi-TTI scheduling mode, the terminal can determine that the target DCI includes a second information field according to the indication of the third signaling sent by the base station, thereby determining the target number of TTIs scheduled by the target DCI based on the second information field, which is simple to implement and has high availability.

[0221] In some optional embodiments, reference Figure 17 As shown, Figure 17 The following is a flow chart of an information transmission method according to an embodiment. The method may include the following steps:

[0228] In step 1802, in response to determining that multiple transmission time intervals (TTIs) scheduling needs to be performed through target downlink control information (DCI), the base station determines a target DCI including a first information field for indicating a target scheduling mode.

[0229] The target scheduling mode includes a first multi-TTI scheduling mode or a second multi-TTI scheduling mode.

[0230] In step 1803, in response to the target scheduling mode including the second multi-TTI scheduling mode, the base station determines a target DCI, where the target DCI includes at least a second information field for indicating a target number of TTIs scheduled by the target DCI.

[0233] In step 1806, the terminal determines the target number of TTIs scheduled by the target DCI according to the second information field in the target DCI.

[0234] In the above embodiment, the base station can directly send the target scheduling mode corresponding to the target DCI and the number of TTIs scheduled by the target DCI to the terminal through the target DCI, without using other signaling to inform the terminal, thereby saving signaling resources, achieving the purpose of scheduling multiple identical or different transmission blocks through the target DCI, and improving the flexibility of multi-TTI scheduling.

[0238] In step 1902, in response to the multi-transmission time interval TTI scheduling performed through the target downlink control information DCI, the base station determines a target RNTI corresponding to the target scheduling mode according to the correspondence between different radio network temporary identifiers RNTIs and different scheduling mode indication information.

[0239] The target scheduling mode is a scheduling mode corresponding to the target DCI, including a first multi-TTI scheduling mode or a second multi-TTI scheduling mode.

[0240] In step 1903, in response to the target scheduling mode including the second multi-TTI scheduling mode, the base station determines a target DCI, where the target DCI includes at least a second information field.

[0241] In step 1904, the target DCI including the second information field is scrambled using the target RNTI.

[0242] In step 1905, the base station sends the target DCI scrambled by the target RNTI.

[0243] In step 1906, the terminal determines the target scheduling mode indication information corresponding to the target RNTI for scrambling the target DCI according to the correspondence between different radio network temporary identifiers RNTIs and different scheduling mode indication information.

[0246] In the above embodiment, the base station can send the target scheduling mode corresponding to the target DCI to the terminal by scrambling the target DCI with the target RNTI, thereby saving DCI resources. Furthermore, the base station can send the number of TTIs scheduled by the target DCI to the terminal via the target DCI. This achieves the purpose of scheduling multiple identical or different transport blocks using the target DCI, improving the flexibility of multi-TTI scheduling.
