Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a data scheduling method, device, and storage medium. Background Art

[0002] The upper layer configures the maximum number of data transmission blocks A (e.g., A = 8 or 4) that can be scheduled for each DCI (Downlink Control Information).

Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0098] The embodiments of the present application provide a data scheduling method and apparatus to implement multi-data scheduling of non-continuous HPN numbers, increase the flexibility of base station scheduling, and avoid the defect of HPN number conflicts in special scenarios.

[0099] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0100] The technical solution provided in the embodiment of the present application can be applicable to a variety of systems, especially 5G systems. For example, the applicable system can be a global system of mobile communication (GSM) system, a code division multiple access (CDMA) system, a wideband code division multiple access (WCDMA) general packet radio service (GPRS) system, a long term evolution (LTE) system, a LTE frequency division duplex (FDD) system, a LTE time division duplex (TDD) system, an advanced long term evolution (LTE-A) system, a universal mobile telecommunication system (UMTS), a world-wide interoperability for microwave access (WiMAX) system, a 5G new air interface (NR) system, etc. These various systems include terminal equipment and network equipment. The system may also include a core network part, such as an evolved packet system (EPS), a 5G system (5GS), etc.

[0101] In order to better introduce the various embodiments of this application, the following information is first introduced:

[0102] (1) Explanation of professional terms;

[0103]

[0104]

[0105] (2)HARQ process;

[0106] In wireless communication environments, channel quality changes rapidly, meaning data transmission errors may occur. To improve data transmission reliability and meet the different transmission quality requirements of different services, the standard adopts the HARQ process (Hybrid Automatic Repeat Request). This process involves the receiver decoding the received data and feeding the decoding result back to the transmitter. When the decoding result is correct, an ACK (Acknowledgement) is fed back; when the decoding result is incorrect, a NACK (Negative Acknowledgement) is fed back. The data transmitter determines whether to retransmit the data based on the decoded feedback information received. Generally, if the feedback information received by the data transmitter is NACK, the data is retransmitted. If the feedback information received is ACK, the data is not retransmitted, and the data transmission ends.

[0107] Figure 1 This is a schematic diagram of the HARQ process provided by the embodiment of the present application; Figure 1 The following is a HARQ process (assuming that the initial transmission decoding is incorrect and the secondary transmission decoding is correct):

[0108] 1: The transmitter (gNB) sends a transport block (TB1) to the receiver (UE) for the first time, and carries the HPN number in the scheduling signaling.

[0109] 2: The receiving end (UE) decodes TB1 and finds an error. It then feeds back a NACK to the base station in the uplink resource indicated by the scheduling signaling.

[0110] 3: The gNB receives a NACK message, indicating that the UE did not correctly receive TB1. It then retransmits TB1. The scheduling signaling carries the same HPN number as the initial transmission.

[0111] 4: The receiving end (UE) decodes TB1 again (possibly combining it with the previous data). The decoding result is correct. An ACK is sent back to the data transmitter. The transmitting end (gNB) receives the ACK, indicating that the UE has correctly received TB1, completing the data transmission process.

[0112] (3) Timing constraints in the HARQ process;

[0113] Figure 2 Schematic diagram of timing constraints in the HARQ process provided by an embodiment of the present application, such as Figure 2As shown, under normal circumstances, after receiving the scheduled data, the terminal receives, decodes, and feeds back HARQ-ACK information. During the period from receiving data to feeding back HARQ-ACK, the terminal is considered "busy" and does not want to be interrupted after receiving. That is, when the terminal is receiving and processing a specific HARQ process (identified by HPN, such as HPN=7), before feeding back HARQ-ACK, it does not want to receive data from the same HARQ process (such as HPN=7). That is, before feeding back HARQ-ACK for the PDSCH scheduled by the same HPN, the UE does not want to receive the PDSCH of the same HPN.

[0114] In the above scenario, when a single DCI schedules a single TB, the base station can easily comply with the above restrictions through scheduling. When supporting single DCI scheduling of multiple TBs, which requires continuous HPN, the probability of occurrence increases significantly.

[0115] (4) Processing method when PDSCH configuration for Semi-Persistent Scheduling (SPS) and dynamic scheduling use the same HPN; / Processing method when DG-CG use the same HPN;

[0116] The communication system supports dynamic scheduling (that is, DCI scheduling) and configuration scheduling (based on high-level signaling configuration, such as SPS configuration). During configuration, the configuration scheduling will be divided into a dedicated HPN number. The HPN of dynamic scheduling is indicated in the DCI. Generally, the HPN number of dynamic scheduling is not the same as the HPN number of SPS. However, when the dynamic HPN number is insufficient, the HPN number of SPS can be temporarily used. When the HPN number of DCI scheduling is the same as the HPN number of SPS, the communication system considers that the PDSCH cache of SPS needs to be cleared so that the PDSCH based on DCI scheduling can be received.

[0117] Figure 3 This is a schematic diagram of clearing the SPS PDSCH receiving buffer for DCI scheduling provided by an embodiment of the present application, such as Figure 3As shown, ① refers to the terminal receiving SPS PDSCH-1, which has a decoding error and puts PDSCH-1 into the buffer, awaiting retransmission; ② refers to the terminal receiving DCI scheduling, treating it as new data, and clearing the buffer data; ③ refers to the terminal receiving PDSCH, which has a decoding error and puts PDSCH into the buffer, awaiting retransmission; ④ refers to the terminal receiving SPS PDSCH-2, clearing the buffer, and decoding PDSCH-2. Because the terminal receives data scheduling from the same HPN, according to the current protocol, it treats it as new data. Therefore, in step 2, the buffer of SPS PDSCH-1 is cleared, and the transmission of SPS PDSCH-1 is interrupted. Similarly, in step 4, due to the arrival of SPS PDSCH-2, the terminal clears the DCI-scheduled PDSCH, and the transmission of the DCI-scheduled PDSCH is interrupted.

[0118] The above scenario rarely occurs when a single DCI schedules a single TB. When a single DCI schedules multiple TBs and requires continuous HPNs, the probability of occurrence increases significantly.

[0119] (5) Multi-PUSCH scheduling mechanism based on continuous HPN number allocation;

[0120] Existing communication systems support scheduling multiple PUSCHs with a single DCI. The HPN allocation is continuous. In the DCI information, 4 bits are used to indicate the HPN number of the first PUSCH data transmission block. The HPN of the second PUSCH is incremented by 1, the HPN of the second PUSCH is incremented by 2, and so on.

[0121] Figure 4 Schematic diagram of the HPN allocation mechanism for DCI scheduling multiple PUSCHs provided in an embodiment of the present application, such as Figure 4 As shown, when one DCI schedules 6 PUSCHs, the HPN number of PUSCH1 is indicated by the DCI, and the HPN number of subsequent PUSCHs is obtained by incrementing by one.

[0122] It should be noted that Figure 4 PUS n in can be PUS 1, PUS 2, PUS 3, PUS 4, PUS5, or PUS 6.

[0123] For high-frequency 52.6 GHz operation, scheduling based on multiple data transmission blocks becomes the norm due to the use of high SCS parameters (e.g., SCS = 480 / 960 kHz). As a result, the continuous HPN number allocation mechanism has serious drawbacks, mainly:

[0124] 1: When the HPN number conflicts with the SPS PDSCH, the DCI dynamic scheduling and SPS scheduling interrupt each other's retransmission mechanism.

[0125] 2: When single PDSCH scheduling is used, the transmission of multiple consecutive HPNs cannot be performed due to the limitation of HARQ-ACK feedback timing.

[0126] Note: The use of one DCI scheduling multiple PUSCHs in a communication system is an unlicensed spectrum operation. Its primary purpose is to reduce scheduling signaling overhead and mitigate channel loss scenarios caused by missed DCI scheduling signaling by terminals. Furthermore, in unlicensed spectrum, the simultaneous use of multiple PUSCHs and configuration-based PUSCH scheduling can be reduced. Furthermore, when HPN conflicts between configuration-based PUSCH scheduling and dynamically scheduled HPNs occur, the uplink resolution mechanism differs from the downlink. Therefore, issues related to unlicensed spectrum operations can be ignored.

[0127] In high-frequency technology research, to reduce the need for high subcarrier spacing and the new demand for PDCCH channel detection capabilities in scenarios where multiple PDSCHs / PUSCHs are needed, a single DCI can be used to schedule multiple PDSCHs / PUSCHs, with each data channel transmitting a different data transport block (TB). Regarding multi-PUSCH scheduling, the upper layer can configure the maximum number of TBs N that can be scheduled per DCI (e.g., N = 8 or 4). In the scheduling DCI, 4 bits are used to indicate the HPN number of the first data transport block transmitted on the PUSCH. The HPN numbers of subsequent data transport blocks are incremented by 1, meaning that the HPN numbers for multiple data transport blocks are continuous. This continuous HPN scheduling mechanism imposes significant constraints on base station scheduling, for example, avoiding the HPN number of the SPS PDSCH, as previously scheduled HPN numbers are subject to the time constraint of k1.

[0128] Therefore, the present application proposes a data scheduling method and device, which will be described in conjunction with the following embodiments.

[0129] Figure 5 This is a flow chart of the data scheduling method provided in the embodiment of the present application. Figure 5 As shown, the method includes the following steps:

[0130] Step 500: Send first scheduling indication information to a terminal, where the first scheduling indication information is used to instruct the terminal to send or receive a first data transmission block to be scheduled;

[0131] The hybrid automatic repeat request process identifiers HPN corresponding to the first data transmission blocks to be scheduled are discontinuous.

[0132] Optionally, each first data transmission block to be scheduled corresponds to a hybrid automatic repeat request process identifier HPN, and the hybrid automatic repeat request process identifier HPN corresponding to each first data transmission block to be scheduled is different, and the HPNs of the first data transmission blocks to be scheduled are discontinuous.

[0133] Optionally, scheduling of data transmission blocks corresponding to some HPN numbers may be skipped through high-layer protocol configuration and / or physical layer indication.

[0134] Optionally, the network side may send first scheduling indication information to the terminal, instructing the terminal to send or receive a first data transmission block to be scheduled with a discontinuous HPN.

[0135] Optionally, when the sending end is a terminal and the receiving end is a network side, the terminal may send first scheduling indication information to the network side, where the first scheduling indication information is used to instruct the network side to send or receive a first data transmission block to be scheduled;

[0136] The hybrid automatic repeat request process identifiers HPN corresponding to the first data transmission blocks to be scheduled are discontinuous.

[0137] Optionally, part or all of the first data transmission blocks to be scheduled constitute the data to be scheduled.

[0138] Optionally, indication information may be added to the DCI to indicate the HPN number included in the scheduling signaling.

[0139] For example, the first scheduling indication information may be based on a DCI indication, that is, the terminal may determine the HPN numbers of the scheduling data included in the scheduling signaling based on the DCI indication.

[0140] The embodiment of the present application supports a discontinuous HPN number scheduling mechanism, that is, data transmission blocks corresponding to one or more HARQ processes are not scheduled.

[0141] The data scheduling method provided in the embodiment of the present application instructs the terminal to send or receive a first data transmission block with discontinuous HPN numbers through the first scheduling indication information, thereby realizing multi-data scheduling of discontinuous HPN numbers, increasing the flexibility of base station scheduling, and avoiding the defect of HPN number conflicts in special scenarios.

[0142] Optionally, according to the data scheduling method of one embodiment of the present application, the instructing the terminal to send or receive the first data transmission block to be scheduled includes:

[0143] Instructing to schedule first data transmission blocks corresponding to N to-be-scheduled HPNs, and / or not to schedule second data transmission blocks corresponding to M unscheduled HPNs;

[0144] Optionally, N+M may be the maximum number of DCI scheduled data transmission blocks;

[0145] Optionally, the first scheduling information may be included in DCI, and the DCI may indicate that all scheduled data transmission blocks include the first data transmission block and the second data transmission block.

[0146] Optionally, the terminal may send or receive data or data blocks consisting of all first data transmission blocks based on the first scheduling indication information.

[0147] Wherein, M is an integer greater than 0, N is an integer greater than or equal to 1, and the sum of M and N is a specific value, which is predefined or pre-configured by the base station or pre-specified by the protocol.

[0148] Optionally, the network side may instruct the terminal to schedule the first data transmission blocks corresponding to one or more HARQ processes.

[0149] Optionally, the network side may indicate the second data transmission block corresponding to one or more HARQ processes that are not scheduled by the terminal.

[0150] Optionally, the network side may simultaneously instruct the terminal to schedule a first data transmission block corresponding to one or more HARQ processes and a second data transmission block corresponding to one or more unscheduled HARQ processes.

[0151] Optionally, the number of first data blocks may be N, where N may be an integer greater than or equal to 0.

[0152] Optionally, the number of first data blocks may be M, where M may be an integer greater than 0.

[0153] Optionally, the sum of M and N is a specific value, which is predefined or preconfigured by the base station or pre-specified by a protocol.

[0154] Optionally, when the transmitting end is a terminal and the receiving end is a network side, the terminal may instruct the network side to schedule first data transmission blocks corresponding to N to-be-scheduled HPNs, and / or not schedule second data transmission blocks corresponding to M unscheduled HPNs;

[0155] For example, the length of the first scheduling indication information may be N+M bits, that is, indicating whether the data transmission blocks corresponding to N+M HPN numbers are scheduled, that is, simultaneously instructing the terminal to schedule the first data transmission blocks corresponding to N HARQ processes and the second data transmission blocks corresponding to M unscheduled HARQ processes;

[0156] Optionally, the number of bits indicating the HPN may be reduced through the DCI.

[0157] It can be understood that N+M can be the maximum number of DCI scheduled data transmission blocks.

[0158] Optionally, according to the data scheduling method according to an embodiment of the present application, the first scheduling indication information includes:

[0159] HPN indication information, used to indicate the HPN of the first first data transmission block to be scheduled; and

[0160] The second scheduling indication information is used to indicate that the non-first to-be-scheduled first data transmission blocks corresponding to N-1 to-be-scheduled HPNs are scheduled, and / or that the second data transmission blocks corresponding to M unscheduled HPNs are not scheduled.

[0161] Optionally, the network side may indicate the HPN of the first data transmission block to be scheduled by the terminal through HPN indication information in the DCI information, and then indicate the scheduling status of several consecutive data transmission blocks after the first scheduled first data transmission block in sequence through second scheduling indication information.

[0162] Optionally, the network side may add a second scheduling indication information in the DCI. The second scheduling indication information may be (M+N-1) bits long. It is used to indicate whether the data transmission blocks corresponding to the (M+N-1) consecutive HPN numbers after the HPN corresponding to the first scheduled first data transmission block are scheduled. The indication information may be defined as follows:

[0163] Scheduled-TBs-HPN-indication:M+N-1bit(s)

[0164] Optionally, M+N may be the maximum number of TBs supported by a single DCI configured by the protocol.

[0165] Optionally, 1 indicates that the TB with the corresponding HPN number is scheduled, and 0 indicates that the TB (Transport Block) with the corresponding HPN number is not scheduled.

[0166] Optionally, 0 indicates that the TB with the corresponding HPN number is scheduled, and 1 indicates that the TB with the corresponding HPN number is not scheduled.

[0167] Figure 6 This is one of the schematic diagrams of the data scheduling indication method provided in the embodiment of the present application, such as Figure 6 As shown, 1 indicates that the TB with the corresponding HPN number is scheduled, and 0 indicates that the TB with the corresponding HPN number is not scheduled. Multiple data transmission blocks are scheduled on the PDSCH, and M+N=6.

[0168] like Figure 6As shown, 4 bits of HPN indication information are used to indicate the information of the first scheduled PDSCH. For example, if HPN=2, both the terminal and the base station can assume that the data transmission block with HPN=2 is scheduled. The 5-bit information Scheduled-TBs-HPN-indication is used to indicate whether the TBs of the other five HPNs are scheduled, for example, indicating that the data transmission block with HPN=2+1=3 is scheduled; indicating that the data transmission block with HPN=2+2=4 is scheduled; indicating that the data transmission block with HPN=2+3=5 is not scheduled; indicating that the data transmission block with HPN=2+4=6 is scheduled; and indicating that the data transmission block with HPN=2+5=7 is scheduled.

[0169] Among them, in one data scheduling signaling:

[0170] The DCI can indicate the HPN information of the first scheduled PDSCH through the HPN indication information; the HPNs of other possible scheduled PDSCHs are incremented by 1. (For example, HPN=2. Then there are a total of up to M+N=6 possible scheduled PDSCH data, and their corresponding HPN numbers are: 2, 3, 4, 5, 6, 7.

[0171] The second scheduling indication information may use (M+N-1) bits to indicate whether data has been scheduled for the other (M+N-1) corresponding HPN numbers. For example, when the bitmap is 1, it indicates that data for the corresponding HPN number has been scheduled; and when the bitmap is 0, it indicates that data for the corresponding HPN number has not been scheduled.

[0172] It should be noted that when the number of HPN bits is 4, the HPN range is 0-15 (or 1-16). When the HPN number calculated above is greater than 15, the data can be modulo-ed. For example, when the HPN indicated by the DCI is 14, the HPN of the first scheduled data transmission block TB1 is 14, the HPN of TB2 is 15, the HPN of TB3 is 0, the HPN of TB4 is 1, the HPN of TB4 is 2, and the HPN of TB4 is 3. Other embodiments are similar and will not be described in detail.

[0173] Optionally, according to the data scheduling method of an embodiment of the present application, the second scheduling indication information is bitmap information, and the length of the second scheduling indication information is N+M-1 bits;

[0174] The bitmap is 0 for indicating that the second data transmission block corresponding to the bit position is not scheduled, and the bitmap is 1 for indicating that the first data transmission block corresponding to the bit position is scheduled; or

[0175] The bitmap is 1 and is used to indicate that the second data transmission block corresponding to the bit position is not scheduled; the bitmap is 0 and is used to indicate that the first data transmission block corresponding to the bit position is scheduled.

[0176] Optionally, when simultaneously indicating whether N+M-1 data transmission blocks are scheduled, the length of the second scheduling indication information can be N+M-1 bits; optionally, the second scheduling indication information is bitmap information, and the bitmap (i.e., the value corresponding to the bit) is 0 to indicate that the second data transmission block corresponding to the bit is not scheduled; the bitmap is 1 to indicate that the first data transmission block corresponding to the bit is scheduled.

[0177] Optionally, according to the data scheduling method according to an embodiment of the present application, the first scheduling indication information includes:

[0178] HPN indication information, used to indicate the HPN of the first first data transmission block to be scheduled; and

[0179] HPN offset factor index information;

[0180] The HPN-offset index information corresponds to a value set of the HPN offset factor;

[0181] The value set of the HPN offset factor includes the value of the HPN offset factor of the first data transmission block and the value of the HPN offset factor of the second data transmission block.

[0182] Optionally, the HPN-offset index information corresponds one-to-one to a value set of the HPN offset factor.

[0183] Optionally, each piece of HPN-offset index information corresponds to a value set of an HPN offset factor, and different pieces of HPN-offset index information correspond to different value sets of HPN offset factors.

[0184] Optionally, offset-related information of the scheduling HPN number, such as an offset factor index, may be configured in the first scheduling indication information.

[0185] For example: time-domain-list = {scheduling data starting symbol information, scheduling data length information, HPN_offset}. Offset is the HPN offset value of the scheduling data. When offset is a special value (such as = -1), it means skipping the data transmission block corresponding to the HPN_offset.

[0186] Optionally, when the base station configures the time domain information parameters, a parameter of the offset factor HPN_offset may be added. Different HPN_offset parameters generate different index indication items, which are indicated by the first scheduling indication information, such as DCI.

[0187] Optionally, when the HPN_offset value is a specific value (such as "x" or "null"), it can be considered that the scheduling skips the corresponding HPN number.

[0188] For example, time domain scheduling parameters: time-domain-list={

[0189] DCI-Index0: scheduling data starting symbol information, scheduling data data length, HPN_offset{0,1,2,3};

[0190] DCI-index1: scheduling data starting symbol information, scheduling data length, HPN_offset{0,1,x,3};

[0191] DCI-index2: scheduling data starting symbol information, scheduling data length, HPN_offset{0,1,x,x};\

[0192] }

[0193] Among them, when DCI scheduling, when the time domain parameter in DCI is DCI-Index0, it means that the PDSCHs of the four corresponding HPNs are scheduled.

[0194] In DCI scheduling, when the time domain parameter in the DCI is DCI-Index1, it indicates that 3 PDSCHs corresponding to HPNs are scheduled (offsets are 0, 1, and 3, respectively, and offset 2 is not scheduled)

[0195] In DCI scheduling, when the time domain parameter in the DCI is DCI-Index2, it indicates that two PDSCHs corresponding to HPNs are scheduled (offsets 0 and 1, and offsets 2 and 3 are not scheduled).

[0196] Figure 7 This is a second schematic diagram of the data scheduling indication method provided in an embodiment of the present application, such as Figure 7 As shown, 1 indicates that the TB with the corresponding HPN number is scheduled, and 0 indicates that the TB with the corresponding HPN number is not scheduled. Multiple TBs are scheduled in PDSCH, and M+N=4.

[0197] Among them, the DCI-index indication is 2, that is, HPN_offset{0,1,x,x}, ​​that is Figure 7 The data transmission block corresponding to HPN=10 / 11 is not scheduled.

[0198] like Figure 7As shown, when DCI scheduling, the time domain indication information is DCI-Index2, and the HPN indication is 8, which means that 2 PDSCHs corresponding to HPN are scheduled (HPN=8 and 9 respectively), which means that 2 PDSCHs corresponding to HPN are not scheduled (HPN=10 and 11 respectively).

[0199] Optionally, the first scheduling indication information, such as DCI, may indicate the HPN information of the first scheduled PDSCH through HPN indication information; the HPNs of other possible scheduled PDSCHs may increase the offset factor. For example, if the HPN of the first scheduled data is 8, there are a total of up to N=6 possible scheduled PDSCH data, and their corresponding HPN numbers are: 8+0, 8+1 or x, 8+2 or x, 8+3 or x, 8+4 or x, and 8+5 or x. The offset factor is indicated by the time domain scheduling parameter.

[0200] Optionally, according to the data scheduling method of an embodiment of the present application, the value of the HPN offset factor of the second data transmission block is a first preset value, and the first preset value is predefined or pre-configured by the base station or pre-specified by the protocol.

[0201] Optionally, it can indicate whether the data transmission block corresponding to the corresponding offset factor is scheduled. When the offset factor is a special value (such as x or Null), it can be considered that the HPN number is invalid, or the corresponding time domain information does not schedule a data packet. That is, when the offset factor is a special value, the corresponding data transmission block is an unscheduled second data transmission block. When the offset factor is not a special value, it can be considered that the HPN number is valid, or the corresponding time domain information schedules a scheduled data packet.

[0202] Optionally, the special value of the offset factor corresponding to the second data transmission block can be a first preset value predefined by the communication system, preconfigured by the base station, pre-specified by the protocol, or indicated by a higher layer of the network, for example, indicating that the first preset value is x.

[0203] Optionally, according to the data scheduling method of an embodiment of the present application, the correspondence between the HPN-offset index information and the HPN-offset value set is predefined or pre-configured by the base station or pre-specified by a protocol.

[0204] Optionally, the correspondence between the HPN-offset index information and the HPN-offset value set may be predefined or pre-configured by the base station or pre-specified by a protocol or indicated by a higher layer of the network.

[0205] For example, the correspondence between the HPN-offset index information and the HPN-offset value set may include:

[0206] DCI-Index0: scheduling data starting symbol information, scheduling data data length, HPN_offset{0,1,2,3};

[0207] DCI-index1: scheduling data starting symbol information, scheduling data length, HPN_offset{0,1,x,3};

[0208] DCI-index2: scheduling data starting symbol information, scheduling data length, HPN_offset{0,1,x,x}.

[0209] It should be noted that the above correspondence between the HPN-offset index information and the HPN-offset value set is only an example and is not intended to limit the embodiments of the present application.

[0210] Optionally, according to a data scheduling method of an embodiment of the present application, when the number of bits of the HPN indication information is smaller than a threshold value, the N HPNs to be scheduled and / or the M unscheduled HPNs are calculated based on the values ​​corresponding to the HPN indication information, and the threshold value is predefined or pre-configured by the base station or pre-specified by the protocol.

[0211] Optionally, when the number of bits of the HPN indication information is smaller than a threshold value, the N to-be-scheduled HPNs and / or the M unscheduled HPNs are obtained by calculation based on values ​​corresponding to the HPN indication information.

[0212] Optionally, to save signaling overhead, the actual value of the first HPN to be scheduled may be set to be larger than the value range corresponding to the bit size of the HPN indication information, and then the actual value of the first HPN to be scheduled may be obtained by performing corresponding calculations on the value of the HPN indication information.

[0213] Optionally, according to a data scheduling method according to an embodiment of the present application, calculating and obtaining the values ​​corresponding to the HPN indication information of the N to-be-scheduled HPNs and / or the M unscheduled HPNs includes:

[0214] The HPN of the first data transmission block to be scheduled is obtained by multiplying or adding a value corresponding to the HPN indication information and a second preset value, where the second preset value is predefined or preconfigured by a base station or predefined by a protocol.

[0215] Optionally, since the actual value of the first HPN to be scheduled is larger than the value range corresponding to the bit size of the HPN indication information, the actual value of the first HPN to be scheduled can be obtained by multiplying or adding the value corresponding to the HPN indication information and the second preset value.

[0216] Optionally, the value range of the second preset value is an integer that is a power of 2.

[0217] Optionally, according to a data scheduling method in an embodiment of the present application, when the number of bits of the HPN indication information is greater than or equal to a threshold value, the value of the first HPN to be scheduled is equal to the value corresponding to the HPN indication information.

[0218] Optionally, when the actual value of the first HPN to be scheduled is less than or equal to the value range corresponding to the bit size of the HPN indication information, the value corresponding to the HPN indication information may be directly used to represent the actual value of the first HPN to be scheduled.

[0219] Optionally, after obtaining the actual value of the first HPN to be scheduled, since the HPNs composed of all subsequent scheduled and unscheduled data transmission blocks are continuous, the HPN value of each transmission data block is the value of the previous HPN transmission block plus one.

[0220] Optionally, it may be assumed that the data transmission block corresponding to the first HPN number indicated by the first scheduling indication information, such as the first HPN number indicated by the DCI, is scheduled, that is, the first HPN number indicated by the first scheduling indication information is the HPN indication information.

[0221] Optionally, taking the second preset value as 4 as an example, in order to reduce the number of bits used to represent the HPN number (for example, N bits can be reduced to N-2 bits), the terminal can calculate the HPN number of the first scheduled TB, for example, by multiplying it by the second preset value 4. The indication information can be defined as follows:

[0222] Scheduled-TBs-HPN-indication:N+M bit(s)

[0223] N+M is the maximum number of TBs that can be scheduled on a single DCI as configured by the protocol. 1 indicates that the TB with the corresponding HPN number is scheduled, and 0 indicates that the TB with the corresponding HPN number is not scheduled.

[0224] Or vice versa;

[0225] Figure 8 This is a third schematic diagram of the data scheduling indication method provided in an embodiment of the present application, such as Figure 8 As shown, 1 indicates that the TB with the corresponding HPN number is scheduled, and 0 indicates that the TB with the corresponding HPN number is not scheduled. Multiple data transmission blocks are scheduled on the PDSCH, where N+M=6.

[0226] like Figure 8As shown, 2 bits of HPN indication information are used to indicate the information of the first scheduled PDSCH, such as: HPN=2. Then the terminal and the base station can both consider HPN=2*4=8 as the HPN of the first data transmission block to be scheduled. The 6-bit information Scheduled-TBs-HPN-indication is used to indicate whether the TBs of a total of 6 HPNs are scheduled, such as indicating that the data transmission blocks with HPN=8 and HPN=8+3=11 are not scheduled.

[0227] Optionally, the DCI and a second preset value, such as a multiplication factor, indicate the HPN information of the first scheduled PDSCH; the HPNs of other possible scheduled PDSCHs are incremented by 1. (For example, if HPN=2, the multiplication factor is 4). Thus, there are a total of up to N+M=6 possible scheduled PDSCH data, and their corresponding HPN numbers are: 8, 9, 10, 11, 12, and 13. The multiplication factor here can be indicated by the base station or calculated by the terminal itself;

[0228] For example, when the HPN information length in the DCI is i bits and the actual expected HPN information length is j bits, the multiplication factor is power(2, ji). Power() represents a power exponent.

[0229] In the embodiment of the present application, by setting the actual value of the first HPN to be scheduled to be larger than the value range corresponding to the number of bits of the HPN indication information, and then performing corresponding calculations on the value of the HPN indication information to obtain the actual value of the first HPN to be scheduled, at least 1 bit of overhead can be saved.

[0230] Optionally, according to the data scheduling method of an embodiment of the present application, when the system is preset or the protocol predetermines that only a third data transmission block having an HPN different from the HPN of the semi-persistently scheduled data transmission block is scheduled by default, the first scheduling indication information includes:

[0231] HPN indication information, used to indicate the HPN of the first data transmission block to be scheduled;

[0232] The HPN of the first data block is determined based on the HPN of the first first data transmission block to be scheduled and the HPN of the third data transmission block.

[0233] Optionally, the HPN of the third data block is different from the HPN of the semi-persistently scheduled data transmission block.

[0234] Optionally, the system may pre-set or the protocol may pre-specify that the terminal or network side skips the HPN for SPSPDSCH by default.

[0235] Optionally, when the base station configures semi-static scheduling for the terminal, one or more HPN numbers for semi-static scheduling will be configured. When the terminal receives multi-data transmission block scheduling signaling, if the HPN in the scheduling includes the HPN number for semi-static scheduling, the terminal can skip the HPN configured for semi-static PDSCH scheduling by default.

[0236] Figure 9 This is a fourth schematic diagram of the data scheduling indication method provided in an embodiment of the present application, such as Figure 9 As shown, assuming that the base station is configured for semi-persistent scheduling with HPN numbers 4 and 5, the terminal will skip the data transmission blocks with HPNs 4 and 5 configured for semi-persistent PDSCH scheduling by default, and the total number of scheduled data transmission blocks is reduced.

[0237] The base station is configured to semi-persistently schedule data transmission blocks with HPN numbers 4 and 5. The terminal may assume that data transmission blocks with HPN numbers 4 and 5 are not scheduled. Only data transmission blocks with HPN numbers 2, 3, 6, and 7 are scheduled.

[0238] Optionally, the first scheduling indication information, such as DCI, can indicate the HPN information of the first scheduled PDSCH; the HPNs of other possible scheduled PDSCHs are incremented by 1, such as HPN=2, then there are a total of up to N+M=6 possible scheduled PDSCH data, and their corresponding HPN numbers are: 2, 3, 4, 5, 6, 7.

[0239] For example, assuming that the higher layer configures HPN 4 and 5 for special scheduling (such as SPS scheduling), and instructs the terminal not to use the HPN based on dynamic scheduling, the terminal can remove the above HPN number, or consider the HPN number used for special scheduling, then the data transmission block corresponding to the above HPN number is not scheduled in this signaling, that is, only the transmission data transmission blocks corresponding to HPNs 2, 3, 6 and 7 are scheduled.

[0240] Figure 10 This is a fifth schematic diagram of the data scheduling indication method provided in the embodiment of the present application, such as Figure 10 As shown, assuming that the base station configures HPN numbers 4 and 5 for semi-persistent scheduling, the terminal will skip HPN numbers 4 and 5 configured for semi-persistent PDSCH scheduling by default, and the total number of scheduled data transmission blocks remains unchanged.

[0241] Assuming that the base station is configured for semi-static scheduling of HPN numbers 4 and 5, the terminal may consider that the data transmission blocks with HPN numbers 4 and 5 are not scheduled, but the total number of scheduled data transmission blocks remains unchanged, that is, HPN=2, 3, 6, 7, 8, and 9 are scheduled.

[0242] Optionally, the first scheduling indication information, such as DCI, may indicate the HPN information of the first scheduled PDSCH; the HPNs of other possible scheduled PDSCHs are incremented by 1. Thus, there are a total of at most N+M=6 possible scheduled PDSCH data transmission blocks, and their corresponding HPN numbers are: 2, 3, 4, 5, 6, 7, and 8, or more.

[0243] Assume that the upper layer configures HPN 4 and 5 for special configuration (such as SPS scheduling) and instructs the terminal not to use the HPN based on dynamic scheduling. The terminal needs to remove the above HPN number, but still keep the total scheduling number unchanged. The terminal then believes that this signaling schedules the transmission data blocks corresponding to HPNs 2, 3, 6, and 7, as well as 8 and 9.

[0244] Optionally, the terminal or the network side may schedule only the third data transmission block by default based on system preset or protocol predefined.

[0245] Optionally, the terminal or the network side schedules only the third data transmission block by default, which may be preset by the system or predefined by the protocol or indicated by a higher layer of the network.

[0246] Optionally, according to the data scheduling method according to an embodiment of the present application, the first scheduling indication information includes:

[0247] HPN indication information, used to indicate the HPN of the first data transmission block to be scheduled;

[0248] The third scheduling indication information is used to instruct the terminal to schedule only the third data transmission block; wherein the HPN of the first data block is determined based on the HPN of the first first data transmission block to be scheduled and the HPN of the third data transmission block, and the HPN of the third data transmission block is different from the HPN of the semi-statically scheduled data transmission block.

[0249] Optionally, the network side may instruct the terminal to skip the HPN for the SPS PDSCH through the third scheduling indication information in the first scheduling indication information.

[0250] Optionally, according to the data scheduling method according to an embodiment of the present application, the third scheduling indication information includes:

[0251] Direct indication information, used to directly indicate whether to schedule or not schedule the fourth data transmission block; and / or

[0252] The indirect indication information is used to indirectly indicate whether to schedule or not schedule the fourth data transmission block by indicating whether the first data transmission block among all data blocks indicated by the scheduled or not DCI is scheduled.

[0253] Optionally, when the base station configures semi-static scheduling for the terminal, it will configure one or more HPN numbers for semi-static scheduling. When the terminal receives multi-data transmission block scheduling signaling, if the HPN in the scheduling includes the HPN number for semi-static scheduling, the terminal can determine whether to skip the HPN configured for semi-static PDSCH scheduling according to the base station indication.

[0254] Optionally, the third scheduling indication information may be a DCI indication. Here, taking the DCI indication as an example, the third scheduling indication information may include but is not limited to the following two types:

[0255] 1: Explicit indication (indicated by direct indication information): that is, the base station can indicate to the terminal in the DCI whether to skip the corresponding HPN if the scheduled HPN includes an HPN number for semi-persistent scheduling, that is, whether the corresponding HPN number is considered to have no scheduled data transmission block.

[0256] 2: Implicit indication (indication through indirect indication information): that is, the terminal can be instructed through information in a special position of other existing information fields whether to skip the corresponding HPN if the HPN in the schedule includes the HPN number used for semi-static scheduling, that is, whether the corresponding HPN number is considered to have no scheduled data transmission block.

[0257] Figure 11 This is a sixth schematic diagram of the data scheduling indication method provided in an embodiment of the present application, such as Figure 11 As shown, taking explicit indication as an example, assuming that the base station is configured for semi-persistent scheduling of HPN numbers 4 and 5. The first scheduling indication information, such as adding 1 bit or multiple bits (such as 2 bits) in the DCI, indicates whether the terminal schedules data transmission blocks with HPNs 4 and 5.

[0258] like Figure 11 As shown, if 1 bit indication is used, 0 indicates that when HPN 4 and / or 5 are included in the schedule, the data of the two HPNs are transmitted, and 1 indicates no transmission, or vice versa.

[0259] like Figure 11 As shown, if a 2-bit indication is used, it indicates whether a data transmission block corresponding to a HPN number is transmitted. 0 indicates that the data corresponding to the HPN is transmitted, 1 indicates that it is not transmitted, or vice versa.

[0260] Take a data scheduling signaling as an example to illustrate:

[0261] The first scheduling indication information, such as DCI, may indicate the HPN information of the first scheduled PDSCH; the HPNs of other possible scheduled PDSCHs are incremented by 1. (For example, if HPN=2, there are a total of up to N=6 possible scheduled PDSCH data, and their corresponding HPN numbers are: 2, 3, 4, 5, 6, 7, 8.

[0262] The base station can indicate (DCI or higher-layer signaling) whether the HPN number used for special configuration (such as SPS scheduling) is scheduled in this signaling. If it indicates 0 (not scheduled), it indicates that the terminal needs to remove the above HPN number. If it indicates 1 (scheduling), it indicates that the terminal does not need to remove the above HPN number.

[0263] In an embodiment of the present application, when it is indicated that some HPNs have no scheduled data, the total number of actually scheduled data transmission blocks may become smaller, or it may be determined that the total number of scheduled data transmission blocks remains unchanged. When the total number of scheduled data transmission blocks remains unchanged, M data transmission blocks are continuously scheduled, where M is the skipped unscheduled second data transmission block.

[0264] Figure 12 This is the seventh schematic diagram of the data scheduling indication method provided in the embodiment of the present application, such as Figure 12 As shown, implicit indication is used as an example for explanation, assuming that the base station is configured for semi-persistent scheduling with HPN numbers 4 and 5. If the HPN at a specific location is the HPN number configured for semi-persistent scheduling, the data of the HPN can be considered scheduled, otherwise it is considered not scheduled.

[0265] When the HPN of the first data transmission block indicated in the DCI is a semi-persistently scheduled HPN, it can be considered that the base station schedules the data of the HPN.

[0266] like Figure 12 As shown, assuming that the specific position is the HPN of the first data transmission block scheduled by DCI, when the HPN of the first data transmission block indicated in DCI is HPN=4 for semi-persistent scheduling, it is considered that HPN=4 and / or HPN=5 have scheduled data. Otherwise, it is considered that no data is scheduled.

[0267] Take a data scheduling signaling as an example to illustrate:

[0268] The first scheduling indication information, such as DCI, may indicate the HPN information of the first scheduled PDSCH; the HPNs of other possible scheduled PDSCHs are incremented by 1, such as HPN = 4. Thus, there are a total of up to M + N = 6 possible scheduled PDSCH data, and their corresponding HPN numbers are: 4, 5, 6, 7, 8, and 9.

[0269] The terminal determines whether the HPN number used for special configuration (such as for SPS scheduling) is scheduled in this signaling based on the HPN of the special position (such as the HPN information of the first scheduled PDSCH).
