[0056] The transmission method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0057] See Figure 2 , Figure 2 This is a flowchart of the transmission method according to an embodiment of this application. Figure 2 As shown, the method is applied to a terminal and may include:

[0058] Step 201: Obtain first information, which is used to indicate a first transmission and a second transmission, or the first information is used to indicate a second transmission.

[0059] Wherein, the first transmission is a PUSCH transmission, and the second transmission is an uplink supplementary transmission. In this embodiment, the first transmission includes, but is not limited to, traditional PUSCH transmission and PUSCH repetition transmission.

[0060] It should be understood that the uplink supplementary transmission mentioned in the embodiments of this application is merely a euphemism for transmissions that can achieve the uplink supplementary transmission function. Specifically, uplink supplementary transmission can be considered as a supplement or auxiliary to PUSCH transmission. By utilizing the time-frequency resources of uplink supplementary transmission to transmit data or DMRS, it can assist in the data or DMRS transmission of PUSCH; or, uplink supplementary transmission can also be an independent uplink transmission with its own scheduling method and transmission mode, and the transmitted content is not limited to data and DMRS.

[0061] In the embodiments of this application, the first transmission and the second transmission can be indicated simultaneously using the first information, or the second transmission can be indicated separately using the first information. For example, the first transmission and the second transmission can be indicated simultaneously using configuration / scheduling information, or the second transmission can be indicated separately using configuration / scheduling information.

[0062] In practical applications, the terminal can obtain the first information through any of the following methods:

[0063] (1) Obtain the first information through UL grant (uplink authorization);

[0064] (2) Obtain the first information through RRC (Radio Resource Control) signaling;

[0065] (3) Obtain the first information through a predefined method.

[0066] In practical applications, such as TDD (Time Division Duplex) systems, special slots may contain deep domain (DL) symbols. Therefore, slot-based scheduling like PUSCH repetition type A or mapping type A cannot utilize flexible slots for transmission using flexible UL symbols. Furthermore, for PUSCH repetition type B, when the time-domain symbol length of an actual repetition is 1, the actual repetition is ignored. These potentially wasted transmission resources can be utilized for auxiliary or supplementary transmission, or even as independent transmissions.

[0067] To fully utilize potentially wasted resources (such as the resources of flexible slots in PUSCH repetition type A, the resources of actual repetitions in PUSCH repetition type B, and slot-based scheduled PUSCHs), in this embodiment, the number of OFDM symbols in the time domain for the second transmission is less than or equal to a first preset number. The first preset number can be a positive integer. Optionally, the first preset number (X) can be 4.

[0068] The first piece of information may include different content:

[0069] In the first scenario, if the first information is used to indicate the first transmission and the second transmission, the first information may include at least one of the following:

[0070] (1) A first indication, wherein the first indication is used to indicate whether the first transmission carries the second transmission, or, wherein the first indication is used to indicate whether the second transmission is enabled.

[0071] (2) The second transmitted time-domain resource allocation information, for example, time-domain resource allocation pattern.

[0072] (3) Frequency domain resource allocation information of the second transmission.

[0073] When the first transmission frequency hopping is disabled, the frequency domain resource allocation method of the second transmission is the same as that of the first transmission. When the first transmission frequency hopping is enabled, the frequency hopping position of the second transmission is the same as the frequency hopping position of the adjacent hop in the first transmission, or the second transmission is used as a new hop. In specific applications, the frequency hopping position of the second transmission is determined by a cycling method based on existing methods. For example, assuming that only two hops are currently supported, when the second transmission is used as the third hop, its frequency hopping position is consistent with the frequency hopping position of the first hop.

[0074] (4) The relationship between the first transmission and the second transmission in the time domain.

[0075] The relationship between the first transmission and the second transmission in the time domain includes:

[0076] The first transmission is located before the second transmission, and there is a time-domain offset between the first transmission and the second transmission; or, the first transmission is located after the second transmission, and there is a time-domain offset between the first transmission and the second transmission.

[0077] Optionally, the first transmission and the second transmission are continuous in the time domain (i.e., there is no time domain offset between the first transmission and the second transmission), or the maximum interval between the first transmission and the second transmission is less than or equal to the number of OFDM symbols of a second preset number (Y). The second preset number is a positive integer, for example, it can be 2.

[0078] (5) Second indication, which indicates whether the current transmission uses the configuration of the second transmission in the case of repeated transmission of the first transmission.

[0079] (6) DMRS (Demodulation Reference Signal) position offset information (alpha_offset), used to represent the time domain offset of the first transmitted DMRS.

[0080] Based on this information, during transmission, the DMRS position is shifted either in the direction of decreasing time-domain OFDM symbol index or in the direction of increasing time-domain OFDM symbol index.

[0081] In the second scenario, if the first information is used to indicate a second transmission, the first information includes at least one of the following:

[0082] (1) The second transmitted time-domain resource allocation information, for example, time-domain resource allocation pattern.

[0083] (2) Frequency domain resource allocation information of the second transmission.

[0084] (3) If data transmission resources exist in the second transmission, then MCS (Modulation and Coding Scheme) is not included. If data transmission resources do not exist in the second transmission, then MCS is not included.

[0085] (4) If data transmission resources exist in the second transmission, NDI (New Data Indication) is included. If data transmission resources do not exist in the second transmission, NDI is not included.

[0086] (5) Information on the Redundancy Version if data transmission resources exist in the second transmission. If data transmission resources do not exist in the second transmission, information on the Redundancy Version is not included.

[0087] (6) The number of HARQ (Hybrid Automatic Repeat Request) processes if data transmission resources exist in the second transmission. If data transmission resources do not exist in the second transmission, the number of HARQ processes is not included.

[0088] (7) Transmission power control command for scheduled PUSCH.

[0089] (8) Padding bits.

[0090] Step 202: Transmit the information according to the first information.

[0091] In this step, the content and method of transmitting the first information may differ depending on the circumstances.

[0092] In the first case of step 201, the transmission for the first transmission may include at least one of the following:

[0093] (1) When data transmission resources exist in the second transmission, the transmission parameters related to the first transmission (such as MCS level) remain unchanged. The available REs (Resource Elements) of the first transmission and the available REs of the second transmission are used as the total available REs for resource mapping. In this way, the actual transmission bit rate can be reduced and the reliability of data transmission can be improved.

[0094] (2) If DMRS transmission resources exist in the second transmission, the DMRS of the first transmission portion can be transmitted according to the existing DMRS transmission process. The first transmission and the second transmission use the same antenna port, or the power deviation between the antenna ports of the first transmission and the second transmission is less than or equal to a second preset value, or the phase between the antenna ports of the first transmission and the second transmission is continuous. The second preset value can be set as needed.

[0095] (3) If DMRS transmission resources exist in the second transmission, the DMRS position of the first transmission is offset according to the DMRS position offset information. Wherein, if the offset DMRS position of the first transmission exceeds the time domain resource range of the first transmission, DMRS transmission resources exceeding the time domain resource range of the first transmission are not transmitted.

[0096] II. In the first case of step 201, the transmission for the second transmission may include at least one of the following:

[0097] 1. For data transmission in the second transmission:

[0098] When data transmission resources exist in the second transmission, the second transmission uses the time-frequency resources available for the first transmission to transmit the same TB (Transport Block) of information as the first transmission. That is, in this case, the second transmission transmits the same TB of information as the first transmission, only increasing the time-frequency resources available for the first transmission. In this way, the actual transmission bit rate can be reduced, and the reliability of data transmission can be improved.

[0099] Optionally, if the second transmission consists entirely of data transmission resources, at least one of the following conditions must be met:

[0100] The first transmission and the second transmission use the same antenna port;

[0101] The power deviation between the first transmission antenna port and the second transmission antenna port is less than or equal to a first preset value;

[0102] The phase between the first transmission antenna port and the second transmission antenna port is continuous;

[0103] The first transmission uses the same precoding parameters as the second transmission;

[0104] The first transmission uses the same spatial filtering parameters as the second transmission.

[0105] 2. For DMRS transmission in the second transmission:

[0106] If DMRS transmission resources exist in the second transmission, the time slot index used in the initialization process of the DMRS sequence is the same as the time slot index of the first transmission, or the time slot index used in the initialization process of the DMRS sequence is the time slot index of the time slot where the second transmission is located.

[0107] Optionally, the transmission also satisfies at least one of the following conditions:

[0108] (1) The DMRS transmission resources of the second transmission of the first target terminal are not fully occupied. The first target terminal can be any terminal. That is, for a certain terminal, since there may be DMRS port multiplexing among multiple terminals, the DMRS transmission resources in the second transmission may not be fully occupied.

[0109] (2) The interval between DMRS positions of the second target terminal within the second transmission is greater than or equal to the number of OFDM symbols of the third preset number. The second target terminal can be any terminal. That is, the second target terminal does not expect the interval between DMRS positions belonging to the second target terminal within the second transmission to be less than the number of OFDM symbols of the third preset number. Wherein, the third preset number (Z) is a positive integer, for example, it can be 2.

[0110] (3) The interval between the DMRS position of the second transmission of the third target terminal and the adjacent DMRS position in the first transmission is greater than or equal to the number of OFDM symbols of the fourth preset number. The third target terminal can be any terminal. That is, the third target terminal does not expect the interval between the DMRS position of the second transmission and the adjacent DMRS position in the first transmission to be less than the number of OFDM symbols of the fourth preset number. Wherein, the fourth preset number (Z) is a positive integer, for example, it can be 2.

[0111] Third, in the second case of step 201, the transmission for the second transmission may include at least one of the following:

[0112] 1. For data transmission in the second transmission:

[0113] If data transmission resources exist in the second transmission, data transmission shall be performed according to the existing data transmission method.

[0114] Optionally, when the second transmission consists entirely of data transmission resources, at least one of the following conditions must be met:

[0115] (1) The first transmission and the second transmission use the same antenna port.

[0116] (2) The power deviation between the antenna port of the first transmission and the antenna port of the second transmission is less than or equal to a third preset value. The third preset value can be set as needed.

[0117] (3) The phase between the first transmission antenna port and the second transmission antenna port is continuous.

[0118] (4) The first transmission uses the same precoding parameters as the second transmission.

[0119] (5) The first transmission uses the same spatial filtering parameters as the second transmission.

[0120] Wherein, the interval between the first transmission adjacent to the second transmission and the second transmission is less than or equal to the number of OFDM symbols of a fifth preset number. Wherein, the fifth preset number (Y) is a positive integer, for example, it can be 2.

[0121] 2. For DMRS transmission in the second transmission:

[0122] If DMRS transmission resources exist in the second transmission, DMRS sequence generation and mapping can be implemented based on existing methods. Optionally, at least one of the following may also be included:

[0123] (1) When DMRS transmission resources exist in the second transmission, the DMRS transmission resources of the second transmission of the third target terminal are not fully occupied. The third target terminal can be any terminal. That is, for a given terminal, since there may be DMRS port multiplexing among multiple UEs, the DMRS transmission resources in the second transmission may not be fully occupied.

[0124] (2) The interval between DMRS positions of the fourth target terminal within the second transmission is greater than or equal to the number of OFDM symbols of the sixth preset number. The fourth target terminal can be any terminal. That is, the fourth target terminal does not expect the interval between its own DMRS positions within the second transmission to be less than the number of OFDM symbols of the sixth preset number. Wherein, the sixth preset number (Z) is a positive integer, for example, it can be 2.

[0125] When all resources in the second transmission are DMRS resources, the DMRS sequence is initialized based on the current timeslot index, which is shared by multiple terminals or multiple adjacent first and second transmissions. The interval between adjacent first and second transmissions is less than or equal to the number of OFDM symbols of a seventh preset number. This seventh preset number (Y) is a positive integer, for example, it can be 2.

[0126] In the above description, the values ​​of the third, fourth, and sixth preset quantities can be equal; the values ​​of the second, fifth, and seventh preset quantities can be equal.

[0127] In this embodiment, the terminal transmits data based on acquired first information, wherein the first information is used to indicate a first transmission and a second transmission, or the first information is used to indicate a second transmission. In this way, utilizing the solution of this embodiment, transmission resources can be fully utilized for the second transmission while the first transmission is being performed, thereby improving resource utilization.

[0128] In this embodiment, the time-domain resource allocation information of the second transmission includes the time-domain resource allocation pattern of the second transmission. In practical applications, the pattern can be obtained through at least one of the following methods:

[0129] (1) Obtained through bitmap: The length of bitmap represents the number of OFDM symbols allocated, "0" indicates that data is transmitted on the symbol, "1" indicates that DMRS is transmitted on the symbol; or vice versa.

[0130] (2) Obtaining by pattern index: Different indices correspond to different patterns. Therefore, the corresponding pattern can be obtained by using the pattern index.

[0131] (3) Obtained through preset rules:

[0132] (a) Determine the pattern based on the location of time-domain resources: when the number of symbols is 1, transmit data or transmit DMRS in a fixed manner; when the number of symbols is 2 / 3, place DMRS in the first or last symbol position, or place multiple or all DMRS to extend UE (User Equipment) multiplexing, or place all data.

[0133] (b) Determine the position of the DMRS of the second transmission based on the positional relationship between the second transmission and the first transmission and the position of the DMRS of the first transmission, ensuring that the intervals are as equal as possible.

[0134] like Figure 3 The diagram shows several possible patterns when the number of OFDM symbols is less than 4.

[0135] Based on the above embodiments, for PUSCH repetition type B transmissions, the first information is further used to indicate that the actual repetition with a time-domain length of 1 is configured as a second transmission. In this case, the transmission methods for the first and second transmissions are as described above.

[0136] During transmission, at least one of the following conditions must be met:

[0137] The second transmission and the first actual repetition use the same antenna port;

[0138] The power deviation between the antenna ports of the second transmission and the first actual repetition is less than or equal to a first preset value;

[0139] The phase between the antenna port of the second transmission and the antenna port of the first actual repetition is continuous;

[0140] The second transmission uses the same precoding parameters as the first actual repetition;

[0141] The second transmission uses the same spatial filtering parameters as the first actual repetition;

[0142] The first actual repetition and the second transmission belong to the same nominal repetition.

[0143] Furthermore, when the second transmission frequency hopping is enabled, the frequency domain resource location of the second transmission is consistent with that of the second actual repetition, wherein the second actual repetition and the second transmission belong to the same nominal repetition.

[0144] As can be seen from the above description, the solution using the embodiments of this application utilizes resources that may be wasted in the prior art, thereby saving resources. At the same time, it can also reduce the actual transmission code rate or improve the channel estimation accuracy, directly or indirectly improving the reliability of transmission, and thus enhancing uplink coverage capability.

[0145] See Figure 4 , Figure 4 This is a flowchart of the transmission method according to an embodiment of this application. Figure 4 As shown, the method is applied to a network device and may include:

[0146] Step 401: Indicate first information to the terminal, wherein the first information is used to indicate the first transmission and the second transmission, or the first information is used to indicate the second transmission.

[0147] The first transmission is a PUSCH transmission, and the second transmission is an uplink supplementary transmission. Specifically, the network device can indicate the first information to the terminal in either of the following ways: via UL grant indication; or via RRC signaling indication.

[0148] The meaning of the first information and the content included in different situations can be referred to the description of the foregoing method embodiments.

[0149] Step 402: Receive the information transmitted by the terminal based on the first information.

[0150] Depending on the information transmitted by the terminal, there are different ways to receive it.

[0151] For example, when the first information is used to indicate a first transmission and a second transmission, the network device can receive data transmitted by the terminal in the case where data transmission resources exist in the second transmission, wherein the second transmission is used as a time-frequency resource available for the first transmission to transmit the same TB of information as the first transmission.

[0152] For example, when the first information is used to indicate a first transmission and a second transmission, the network device can receive data transmitted by the terminal in the second transmission where all data transmission resources are available, wherein the transmission satisfies at least one of the following conditions:

[0153] The first transmission and the second transmission use the same antenna port;

[0154] The power deviation between the first transmission antenna port and the second transmission antenna port is less than or equal to a first preset value;

[0155] The phase between the first transmission antenna port and the second transmission antenna port is continuous;

[0156] The first transmission uses the same precoding parameters as the second transmission;

[0157] The first transmission uses the same spatial filtering parameters as the second transmission.

[0158] For example, when the first information is used to indicate the first transmission and the second transmission, the network device can receive the DMRS resources transmitted by the terminal when there are DMRS transmission resources in the second transmission, wherein the time slot index used in the initialization process of the DMRS sequence is the same as the time slot index of the first transmission, or the time slot index used in the initialization process of the DMRS sequence uses the time slot index of the time slot where the second transmission is located.

[0159] For example, when the first information is used to indicate a first transmission and a second transmission, the network device may perform at least one of the following:

[0160] The data transmitted by the terminal in the second transmission is received when data transmission resources exist. The available REs of the first transmission and the available REs of the second transmission are used as the total available REs for resource mapping.

[0161] The terminal receives DMRS transmitted in the second transmission when DMRS transmission resources are available, wherein the first transmission and the second transmission use the same antenna port, or the power deviation between the antenna port of the first transmission and the antenna port of the second transmission is less than or equal to a second preset value, or the phase between the antenna port of the first transmission and the antenna port of the second transmission is continuous.

[0162] The terminal receives the DMRS transmitted in the second transmission when DMRS transmission resources exist, and obtains the DMRS according to the DMRS position offset information, wherein the position of the DMRS in the first transmission is offset according to the DMRS position offset information.

[0163] For example, when the first information is used to indicate the second transmission, the network device can receive data transmitted by the terminal when all of the second transmission consists of data transmission resources; wherein the interval between the first transmission adjacent to the second transmission and the second transmission is less than or equal to the number of OFDM symbols of a fifth preset number;

[0164] The transmission performed satisfies at least one of the following conditions:

[0165] The first transmission and the second transmission use the same antenna port;

[0166] The power deviation between the first transmission antenna port and the second transmission antenna port is less than or equal to a third preset value;

[0167] The phase between the first transmission antenna port and the second transmission antenna port is continuous;

[0168] The first transmission uses the same precoding parameters as the second transmission;

[0169] The first transmission uses the same spatial filtering parameters as the second transmission.

[0170] For PUSCH repetition type B transmission, the first information is also used to indicate that the actual repetition with a time domain length of 1 is configured as a second transmission.

[0171] In this embodiment, the terminal transmits data based on acquired first information, wherein the first information is used to indicate a first transmission and a second transmission, or the first information is used to indicate a second transmission. In this way, utilizing the solution of this embodiment, transmission resources can be fully utilized for the second transmission while the first transmission is being performed, thereby improving resource utilization.

[0172] For PUSCH mapping type A, the starting symbol of the PUSCH must be the first symbol of a slot. The PUSCH length can be 4-14 OFDM symbols, and the DMRS position is defined relative to the slot start position. Specifically, when the PUSCH does not hop frequencies, the DMRS position is relative to the slot start position; when the PUSCH hops frequencies, the DMRS position is relative to the start position of each hop. The symbol position of the first DMRS is configured by RRC (Radio Resource Control) signaling and can be configured as pos2 (the third symbol) or pos3 (the fourth symbol).

[0173] For PUSCH mapping type B, the starting symbol of the PUSCH can be any symbol in a slot, and the PUSCH length can be 1-14 OFDM (Orthogonal Frequency Division Multiplexing) symbols. When the PUSCH does not hop frequencies, the DMRS position is defined relative to the starting position of the scheduled PUSCH; when the PUSCH hops frequencies, the DMRS position is relative to the starting position of each hop, and the symbol position of the first DMRS is always located at the first symbol of the PUSCH.

[0174] PUSCH can be repeatedly transmitted, supporting repetition type A and mapping type B. Specifically, the number of repetitions and the RV (Redundancy version) order during repetitions are configured via RRC (Radio Resource Control). PUSCH transmits the same TB (Transport Block) on the same symbol position and frequency domain resources in each slot, and each slot can only have one PUSCH transmission opportunity. Considering the ultra-high reliability and ultra-low latency requirements of URLLC (Ultra-Reliable and Low Latency Communications), supporting PUSCH repetition within each slot (mini-slot based PUSCH repetition within a slot) better meets the needs of URLLC services. PUSCH repetition type A can support mapping type A and mapping type B, but it is a slot-based transmission method; while PUSCH repetition type B only supports mapping type B, making it a more flexible mini-slot based transmission.

[0175] For PUSCH repetition type B, one or more temporally consecutive nominal repetitions PUSCH can be configured. These will be further segmented under various conditions, forming a series of actual repetitions PUSCH transmissions based on the original boundaries between nominal PUSCH and the new boundaries created by the segmentation. Segmentation primarily occurs due to time slot boundaries, semi-static DL symbol configuration, and dynamic SFI indicating invalid symbols.

[0176] In NR systems, TDD (Time Division Duplex) configuration can be semi-static or dynamic. Semi-static configuration allows for configuring the TDD configuration period. The first half of a period's slot / symbol can be used as DL (Downlink) resources, with configurable time-domain length. The second half of the period's slot / symbol can be used as UL (Uplink) resources, also with configurable time-domain length. Slots / symbols in the middle of the period are considered flexible resources. These resources can be further configured as DL / UL resources using UE-specific configuration parameters. Dynamic configuration, based on the semi-static configuration as special slot resources, dynamically configures which symbols are used for DL ​​transmission and which for UL transmission.

[0177] In special slots, DL symbols may exist. Therefore, for slot-based scheduling like PUSCH repetition type A, UL symbols in flexible slots cannot be used for transmission, leading to a waste of available resources in some scenarios. Furthermore, for PUSCH repetition type B, when the time-domain symbol length of an actual repetition is 1, the actual repetition will be ignored. Therefore, utilizing these potentially wasted resources to transmit additional data or DMRS can reduce the actual transmission rate or improve channel estimation accuracy, thereby directly or indirectly improving transmission reliability and enhancing coverage.

[0178] To address the aforementioned issues, in the transmission method of this application embodiment, the terminal acquires first information, which is used to indicate a first transmission and a second transmission, or the first information is used to indicate a second transmission. Then, the terminal performs transmission based on the first information. Correspondingly, the network device receives the information transmitted by the terminal.

[0179] In one embodiment, assuming a PUSCH repetition type A transmission is scheduled in a certain UL grant, time-domain resource allocation, DMRS location, etc., are considered. Figure 5 As shown. Among them, in Figure 5 In the diagram, 51 represents the data section, and 52 represents the DMRS section.

[0180] If the following information is also indicated in this UL grant:

[0181] (a) Enable uplink supplementary transmission (second transmission);

[0182] (b) The time-domain resource allocation pattern for the second transmission is as follows: Figure 6 As shown;

[0183] (c) Use the same frequency domain resource allocation as repetition#1 by default;

[0184] (d) This second transmission precedes repetition#1;

[0185] (e) Indicates that only repetition#1 carries the second transmission;

[0186] (f) DMRS position offset alpha_offset = 0, indicating no offset, such as Figure 7 As shown. Figure 7 In the diagram, 71 and 73 are the data sections, and 72 is the DMRS section.

[0187] At this point, repetition #1 and repetition #2, without a second transmission, transmit the same TB. If repetition #1 carries a supplementary transmission, it also transmits the same TB. However, the REs in the data portion of the second transmission are used as REs available for repetition #1 for resource mapping and transmission. This method reduces the final actual transmission bit rate, thereby improving transmission reliability.

[0188] Regarding the placement of DMRS, as follows Figure 7 As shown, the DMRS sequence initialization in the second transmission can be based on the time slot where the second transmission is located, or the DMRS sequence initialization in the second transmission can be based on the time slot where the repetition #1 transmission is located.

[0189] Furthermore, if the time-domain resource allocation pattern of the second transmission is as follows: Figure 8 As shown. If the DMRS position offset alpha_offset indicates that the DMRS position in repetition#1 is offset to the left by 1, then, as Figure 9 As shown. The data transmission and DMRS transmission processes are as described above.

[0190] As can be seen from the above description, in this embodiment of the application, by using the time-domain pattern of the second transmission and the DMRS position offset alpha_offset, a more reasonable and effective data and DMRS transmission configuration can be completed, ensuring that the interval between the second transmission and the DMRS in the first transmission is as uniform as possible and not less than a certain number of OFDM symbols.

[0191] In one embodiment, assuming a PUSCH transmission is scheduled in a certain UL grant, belonging to mapping type B, time-domain resource allocation, DMRS location, etc., are as follows: Figure 10 As shown, Figure 10 In the diagram, 01 represents the DMRS section, and 02 represents the data section.

[0192] In this embodiment, the second transmission can be configured in the same manner as in the previous embodiment, but the configured DMRS position offset alpha_offset indicates that the DMRS position in repetition#1 is offset to the left by 1. Therefore, the final time-domain configuration is as follows: Figure 11 As shown.

[0193] If the time-domain resource allocation pattern is as follows Figure 12 As shown, without configuring the DMRS position offset alpha_offset, the final time-domain configuration is as follows. Figure 13 As shown. In this embodiment, the second transmission can perform data demodulation based on the DMRS channel estimation results in the PUSCH.

[0194] In one embodiment, assuming a TDD system with a frame structure configured as "DDDSU", a PUSCH repetition type A transmission is scheduled via configuredgrant (RRC configuration), and an uplink supplementary transmission (second transmission) is also scheduled. The second transmission is indicated via "1111" or other means, meaning that all four repetitions carry this second transmission. Figure 14 As shown.

[0195] In one embodiment, suppose that UE1's PUSCH1 transmission is scheduled in one UL grant, and UE2's PUSCH2 transmission is scheduled in another UL grant. Simultaneously, uplink supplementary transmissions (second transmissions) at the same location are invoked in both UL grants, and the time-domain resource allocation patterns are consistent, for example, the time-domain resource allocation pattern is as follows: Figure 15 As shown.

[0196] Since UEs do not expect the interval between their own DMRS locations within the second transmission to be less than X OFDM symbols, preferably X = 2, then for a given UE, even if there are 2 available OFDM symbols for DMRS in the time-domain resource allocation pattern, only one may be used in practice. In this case, it can be used as DMRS multiplexing between UE1 and UE2, which can reduce interference and improve the accuracy of channel estimation, such as... Figure 16 As shown.

[0197] At this time, the DMRS sequence initialization on the two OFDM symbols of the second transmission can be based on the current time slot, or the DMRS sequence on the first OFDM symbol can be initialized based on the time slot where PUSCH1 is located, while the DMRS sequence on the second OFDM symbol can be initialized based on the time slot where PUSCH2 is located.

[0198] In one embodiment, assuming a separately indicated uplink supplementary transmission (second transmission) is performed, the scheduling method is basically similar to the existing scheduling method. The main difference lies in the time-domain resource allocation pattern, which can be determined in the following way:

[0199] (1) Bitmap method, for example, using "0" to indicate that the OFDM symbol transmits data, "1" to indicate that the OFDM symbol transmits DMRS, or vice versa.

[0200] For example, "101" can indicate that the second transmission occupies 3 OFDM symbols in the time domain, and its pattern is as follows: Figure 17 As shown. "01" indicates that this second transmission occupies 2 OFDM symbols in the time domain, and its pattern is as follows. Figure 18 As shown.

[0201] (2) The correspondence between predefined indices and patterns, for example, such as Figure 19 As shown.

[0202] (3) Fixed rules, for example:

[0203] i) When the symbol count is 1, DMRS is transmitted in a fixed manner;

[0204] ii) When the number of symbols is 2 or 3, the first OFDM symbol is fixed to place the DMRS, and the remaining symbols can be used to place data or DMRS for UE multiplexing.

[0205] In addition, when performing uplink supplementary transmissions other than the PUSCH transmissions indicated by configuration / scheduling information, the placement of the DMRS should follow these principles:

[0206] i) Ensure that the interval between transmitted DMRS is not less than 2 OFDM symbols; ii) Ensure that the interval between transmitted DMRS is as equal as possible.

[0207] In one embodiment, it is assumed that a separately indicated uplink supplementary transmission (second transmission) is performed, and the time-domain resource allocation pattern indications are all used to transmit DMRS for different UEs. When the time-domain resource allocation pattern indicates DMRS for all UEs, data transmission-related fields in the scheduling / configuration indication information, such as MCS, NDI, RV, HARQ process number, etc., can be ignored. Figure 20 and 21 As shown.

[0208] At this time, the DMRS in the second transmission can perform sequence initialization calculation based on the current time slot, or the DMRS on the first OFDM symbol can perform the same sequence generation and mapping process as the DMRS on the UE2 PUSCH, while the DMRS on the second OFDM symbol can perform the same sequence generation and mapping process as the DMRS on the UE1 PUSCH.

[0209] In one embodiment, for a PUSCH repetition type B transmission with a certain time-domain resource allocation, the nominal repetition is divided into several actual repetitions by the slot boundary, such as... Figure 22 As shown. In actual transmission, since the time domain length of actual repetition#2 is 1, this repetition transmission will be abandoned. At this time, in addition to the PUSCH transmission (first transmission) indicated by the configuration / scheduling information, an uplink supplementary transmission (second transmission) is also indicated, and the actual repetition with a time domain length of 1 will be transmitted according to the second transmission method. The time domain resource allocation pattern of this second transmission indicates that 1 OFDM symbol is used to transmit DMRS, such as... Figure 23 As shown.

[0210] Therefore, both actual repetition #1 and actual repetition #3 can use the DMRS on this second transmission for joint channel estimation. Since actual repetition #1 and actual repetition #2 belong to the same nominal repetition, in the case of frequency hopping, the frequency domain resource location of the supplementary transmission is preferably consistent with the frequency domain resource location of actual repetition #1.

[0211] As can be seen from the above description, the solution using the embodiments of this application can utilize some resources that may be wasted in the existing mechanism to reduce the actual transmission code rate or improve the channel estimation accuracy, thereby directly or indirectly improving the reliability of transmission and enhancing uplink coverage capability.
