Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of communication, and particularly relates to a transmission method and device, user equipment and medium. BACKGROUND

[0002] At present, in a new radio (NR) system, a user equipment (UE) can map a demodulation reference signal (DMRS) in only one uplink transmission of multiple uplink transmissions (for example, a physical uplink shared channel (PUSCH)) sent to a network side device, and maintain the continuity of the transmission power and the transmission phase in the process of sending the multiple uplink transmissions, so that the network side device can perform uplink channel estimation on the multiple uplink transmissions according to the DMRS mapped in the one uplink transmission, to achieve the effect of reducing the number of DMRS and improving the receiving performance of the network side device.

[0003] However, since the transmission power of the UE may change and / or the transmission phase of the UE may change in the process of sending the multiple uplink transmissions by the UE, the network side device may not be able to perform uplink channel estimation on the multiple uplink transmissions, and thus the latency and reliability of the UE sending the uplink channel may be affected.

[0004] Therefore, the performance of the channel sent by the UE is poor. SUMMARY

[0005] Embodiments of the present application provide a transmission method and device, user equipment and medium, which can solve the problem of poor performance of the channel sent by the UE.

[0006] In a first aspect, a transmission method is provided, applied to a UE, and the method comprises: receiving, by the UE, target downlink control information (DCI) from a network side device; adjusting, by the UE, a DMRS pattern in M transmission units corresponding to a first transmission according to a receiving time of the target DCI, M being a positive integer; and transmitting, by the UE, the M transmission units according to the adjusted DMRS pattern.

[0007] In a second aspect, a transmission device is provided, which comprises a receiving module, a processing module and a transmitting module. The receiving module is configured to receive target DCI from a network side device. The processing module is configured to adjust a DMRS pattern in M transmission units corresponding to a first transmission according to a receiving time of the target DCI received by the receiving module, M being a positive integer. The transmitting module is configured to transmit the M transmission units according to the DMRS pattern adjusted by the processing module.

[0008] In a third aspect, a terminal is provided, which comprises a processor, a memory, and a program or instructions stored in the memory and executable on the processor, and the program or instructions, when executed by the processor, implement the steps of the method according to the first aspect.

[0009] In a fourth aspect, a UE is provided, which comprises a processor, a memory, and a program or instructions stored in the memory and executable on the processor, and the program or instructions, when executed by the processor, implement the steps of the method according to the first aspect.

[0010] In a fifth aspect, a readable storage medium is provided, which stores a program or instructions, and the program or instructions, when executed by a processor, implement the steps of the method according to the first aspect or the steps of the method according to the third aspect.

[0011] In a sixth aspect, a chip is provided, which comprises a processor and a communication interface coupled with the processor, and the processor is configured to execute a program or instructions to implement the method according to the first aspect.

[0012] In a seventh aspect, a computer program / program product is provided, which is stored in a non-volatile storage medium, and the program / program product is executed by at least one processor to implement the steps of the method according to the first aspect.

[0013] In the embodiments of the present application, the UE can receive the target DCI from the network side device, and adjust the DMRS pattern in the M transmission units corresponding to the first transmission according to the reception time of the target DCI, and transmit the M transmission units according to the adjusted DMRS pattern. Since the target DCI indicates information that causes the UE to change the transmission power (and / or the transmission phase) during the process of the first transmission, the UE can adjust the DMRS pattern in the M transmission units corresponding to the first transmission according to the reception time of the target DCI to avoid the case that the network side device cannot perform uplink channel estimation on the first transmission, thereby avoiding the case that the delay and reliability of the uplink channel transmitted by the UE are affected, and thus the performance of the uplink channel transmitted by the UE can be improved.

[0051] 1. DMRS bundling

[0052] In the process of multiple uplink transmissions (e.g., multiple PUSCHs), the UE can maintain the continuity of the transmission power and the transmission phase of the UE. In this way, the network side device can obtain the channel information of the other PUSCH transmissions in the multiple PUSCHs based on the DMRS mapped in one of the PUSCHs to perform channel estimation on the multiple PUSCHs when receiving the multiple PUSCHs.

[0053] In the case of using DMRS bundling, the UE can reduce the time domain density of the DMRS symbol of the DMRS mapped in the multiple PUSCHs and adjust (i.e., optimize) the time-frequency position of the DMRS symbol to increase the number of symbols used for transmitting information and improve the reception performance.

[0054] 2. DMRS pattern

[0055] The DMRS pattern is used to indicate the position of the time-frequency resource in which the DMRS exists in the uplink transmission, and / or the position of the RE occupied by the DMRS in the time-frequency resource.

[0062] Figure 2 A flowchart of a transmission method provided by the embodiments of the present application is shown. As shown in Figure 1 The transmission method provided by the embodiments of the present application can include the following steps 101 to 103.

[0063] Step 101, the transmission device receives a target DCI from a network side device.

[0064] Optionally, in embodiments of the present application, the transmission apparatus can receive a physical downlink control channel (PDCCH) from the network side device, and the target DCI is carried on the PDCCH.

[0065] In step 102, the transmission apparatus adjusts a DMRS pattern in the M transmission units corresponding to the first transmission according to a receiving time of the target DCI.

[0066] In embodiments of the present application, M is a positive integer.

[0067] In embodiments of the present application, before the transmission apparatus performs the first transmission, the transmission apparatus can receive the target DCI from the network side device, and adjust the DMRS pattern in the M transmission units corresponding to the first transmission according to a receiving time of the target DCI.

[0068] Optionally, in embodiments of the present application, the M transmission units include a first transmission unit, and the target DCI corresponds to the first transmission unit. The first transmission unit can be at least one of the M transmission units, or the first transmission unit can be the M transmission units.

[0069] Optionally, in embodiments of the present application, the first transmission can be an uplink transmission, and the first transmission can be a transmission enabling DMRS bundling.

[0070] It can be understood that the M transmission units correspond to the transmission enabling DMRS bundling.

[0071] Optionally, in embodiments of the present application, the transmission unit can include any of the following: an orthogonal frequency division multiplexing (OFDM) symbol, a slot, a mini-slot, a subframe, a radio frame, etc. One transmission unit can include one uplink channel or multiple uplink channels.

[0072] Optionally, in embodiments of the present application, the M transmission units can be consecutive transmission units.

[0073] Optionally, in embodiments of the present application, one uplink channel can include any of the following: a physical uplink shared channel (PUSCH) and a physical uplink control channel (PUCCH).

[0074] Optionally, in embodiments of the present application, for each of the M transmission units, the uplink channel on one transmission unit can be the same as or different from the uplink channel on other transmission units (i.e., the M transmission units excluding the one transmission unit).

[0075] Exemplarily, assuming that the M transmission units include a transmission unit 1 and a transmission unit 2, the transmission unit 1 includes one uplink channel, for example, PUSCH, and the transmission unit 2 includes another uplink channel, for example, PUSCH or PUCCH.

[0076] Optionally, in the embodiments of the present application, for each of the M transmission units, in the case that one transmission unit includes multiple uplink channels, the multiple uplink channels can be repeated transmission of the same transport block, or different transport blocks, and the multiple uplink channels can all be the same or partially the same.

[0077] Exemplarily, assuming that the M transmission units include a transmission unit 1, and the transmission unit 1 includes multiple uplink channels, for example, uplink channel 1, uplink channel 2 and uplink channel 3, the uplink channel 1, uplink channel 2 and uplink channel 3 can all be PUSCH (or PUCCH), that is, the uplink channel 1, uplink channel 2 and uplink channel 3 are all the same; or the uplink channel 1 is PUSCH, and the uplink channel 2 and uplink channel 3 are PUCCH, that is, the uplink channel 1, uplink channel 2 and uplink channel 3 are partially the same.

[0078] Optionally, in the embodiments of the present application, the first transmission unit can be a transmission unit affected by the target DCI.

[0079] It should be noted that the "transmission unit affected by the target DCI" can be understood as: the transmission unit indicated by the target DCI to cancel transmission; or, the transmission unit indicated by the target DCI to not perform first transmission; or, the transmission unit overlapping in time domain resource with the transmission scheduled by the target DCI; or, the transmission unit whose starting transmission time is after the starting time of the change of the transmission device's transmission power and / or before the ending time of the change of the transmission device's transmission power; or, the transmission unit adjacent to the transmission scheduled by the target DCI.

[0080] In the embodiments of the present application, the information indicated by the target DCI can affect the transmission behavior of the transmission device, so as to cause the change of the DMRS bundling of the first transmission.

[0081] Optionally, in the embodiments of the present application, the change of the DMRS bundling of the first transmission includes any one of the following: change of the enabling state of the DMRS bundling, and change of the number of transmission units corresponding to the DMRS bundling (DMRS bundling size).

[0082] Further optionally, in the embodiments of the present application, in the case that the fourth condition is not met, the enabling state of the DMRS bundling of the first transmission is changed.

[0083] Exemplarily, in embodiments of the present application, the fourth condition comprises at least one of the following:

[0084] The transmission power (and / or the transmission phase) of the transmission device is unchanged among the M transmission units;

[0085] The interval (GAP) between any two of the M transmission units does not exceed a first preset number of symbols or a second preset number of time slots;

[0086] No frequency switching is performed between any two of the M transmission units;

[0087] No downlink transmission is scheduled between any two of the M transmission units.

[0088] It can be understood that if the fourth condition is not met, it can be considered that during the first transmission, the transmission power of the transmission device may change, and / or the transmission phase of the transmission device may change, that is, the transmission device cannot maintain the continuity of the transmission power and the transmission phase, so that the network side device may not be able to perform uplink channel estimation on the M transmission units corresponding to the first transmission according to the DMRS mapped by one transmission unit (i.e., the one corresponding to the first transmission), and thus the enabling state of the DMRS binding is in the non-enabled state, that is, the first transmission is a transmission that does not enable DMRS binding.

[0089] Further optionally, in embodiments of the present application, the number of transmission units corresponding to the DMRS binding transmission changes when the fifth condition is met.

[0090] Exemplarily, in embodiments of the present application, the fifth condition can be specifically that the transmission scheduled by the target DCI is adjacent to the first transmission.

[0091] Optionally, in embodiments of the present application, the target DCI is used to indicate any of the following:

[0097] The fourth transmission is performed or cancelled on the first serving cell or the first carrier;

[0100] In the embodiments of the present application, the first transmission unit is a transmission unit corresponding to the target DCI among the M transmission units; the third transmission is a downlink transmission, and the time domain resource of the third transmission overlaps the time domain resource of the first transmission; the first serving cell is a serving cell other than the serving cell corresponding to the first transmission; the first carrier is a carrier other than the carrier on which the first transmission is located; and the fifth transmission is bound with the transmission scheduled by other DCI to construct the first transmission.

[0101] Further optionally, in the embodiments of the present application, if the symbol format of the first symbol indicated by the target DCI is the target symbol format, it is possible that a transmission unit among the M transmission units includes the first symbol, and the target symbol format does not match the symbol format corresponding to the first transmission unit, that is, the transmission device can cancel the transmission of the first transmission unit, therefore, it can be considered that the GAP between any two transmission units among the M transmission units can exceed the first preset number of symbols, or the GAP between the two transmission units can exceed the second preset number of slots, that is, the fourth condition is not met, that is, the DMRS binding of the first transmission changes. Wherein, the first transmission unit is a transmission unit in which the time domain position of the first symbol is located.

[0102] It should be noted that the "target symbol format does not match the symbol format corresponding to the first transmission unit" can be understood as: the target symbol format is different from the symbol format corresponding to the first transmission unit.

[0103] Specifically, in the embodiments of the present application, the target symbol format can be any of the following: flexible symbol (flexible), downlink symbol (downlink); and the symbol format corresponding to the first transmission unit is an uplink symbol.

[0104] Further optionally, in the embodiments of the present application, if the target DCI is used to indicate that the transmission of the second symbol is canceled, it is possible that a transmission unit among the M transmission units includes the second symbol, that is, the transmission device can cancel the transmission of the first transmission unit, therefore, it can be considered that the GAP between any two transmission units among the M transmission units can exceed the first preset number of symbols, or the GAP between the two transmission units can exceed the second preset number of slots, that is, the fourth condition is not met, that is, the DMRS binding of the first transmission changes. Wherein, the first transmission unit is a transmission unit in which the time domain position of the second symbol is located.

[0105] Further optionally, in embodiments of the present application, if the target DCI is used to indicate that the first transmission is not performed on the first transmission unit in the case of satisfying the second condition, it can be considered that the GAP between any two of the M transmission units may exceed the first preset number of symbols, or the GAP between any two of the M transmission units may exceed the second preset number of slots, that is, the fourth condition is not satisfied. The first transmission unit is a transmission unit in which the time domain resource of the second transmission overlaps with the time domain resource of the first transmission.

[0106] Further optionally, in embodiments of the present application, if the target DCI is used to indicate that the third transmission is scheduled on the first service cell or the first carrier, it can be considered that the transmission of the first transmission unit corresponding to the first transmission may be affected, so that the GAP between any two of the M transmission units may exceed the first preset number of symbols, or the GAP between any two of the M transmission units may exceed the second preset number of slots, that is, the fourth condition is not satisfied. The first transmission unit is a transmission unit whose starting transmission time is later than the starting transmission time of the third transmission.

[0107] Further optionally, in embodiments of the present application, if the target DCI is used to indicate that the downlink transmission is performed between the two transmission units in which the first transmission is performed, it can be considered that the transmission power of the transmission device may change when the transmission of the first transmission unit corresponding to the first transmission is performed, that is, the fourth condition is not satisfied. The downlink reception can include any of the following: physical downlink shared channel (PDSCH), physical downlink control channel (PDCCH), channel state information-reference signal (CSI-RS). The first transmission unit is a transmission unit whose starting transmission time is later than the starting transmission time of the downlink transmission.

[0108] Further optionally, in embodiments of the present application, in a dual connectivity or carrier aggregation scenario, if the target DCI is used to indicate that the fourth transmission is performed or canceled on the first service cell or the first carrier, it can be considered that the transmission phase of the transmission device may change when the transmission of the first transmission unit corresponding to the first transmission is performed, that is, the fourth condition is not satisfied. The first transmission unit is a transmission unit whose starting transmission time is later than the starting transmission time (or ending transmission time) of the fourth transmission.

[0109] Exemplarily, in the embodiments of the present application, the fourth transmission can include any one of the following: a PUSCH, a PUCCH, a sounding reference signal (SRS), and a physical random access channel (PRACH).

[0110] Further optionally, in the embodiments of the present application, if the target DCI is used to indicate scheduling of a fifth transmission, and the fifth transmission and another transmission scheduled by another DCI are transmitted in adjacent transmission units, it can be considered that the fifth transmission and the another transmission scheduled by the another DCI can enable DMRS bundling to construct the first transmission, that is, the fifth condition is met, that is, the number of transmission units corresponding to DMRS bundling changes. The first transmission unit is the transmission unit corresponding to the another transmission scheduled by the another DCI.

[0111] Exemplarily, in the embodiments of the present application, the fifth transmission can include any one of the following: a configured grant physical uplink shared channel (CG-PUSCH), a PUCCH, an SRS, and a PRACH.

[0112] Further optionally, in the embodiments of the present application, if the target DCI is used to indicate scheduling of a first transmission, and the first transmission and another transmission (for example, a pre-configured scheduled semi-static PDSCH) are transmitted in adjacent transmission units, it can be considered that the first transmission and the another transmission can enable DMRS bundling, that is, the fifth condition is met. The first transmission unit is M transmission units.

[0113] Optionally, in the embodiments of the present application, the second condition includes that the time domain resource of the second transmission scheduled by the target DCI overlaps with the time domain resource of the first transmission, and the priority of the second transmission is higher than the priority of the first transmission.

[0114] Exemplarily, in the embodiments of the present application, the second transmission can include any one of the following: a PUSCH, a PUCCH, an SRS, and a PRACH.

[0115] Optionally, in the embodiments of the present application, in the case of meeting the third condition, the transmission of the first transmission unit is cancelled.

[0116] In the embodiments of the present application, the third condition includes any one of the following:

[0117] The first transmission unit includes a first symbol, and the target symbol format does not match the symbol format corresponding to the first transmission unit;

[0118] The first transmission unit includes a second symbol.

[0119] Further optionally, in the embodiments of the present application, in the case where the target DCI is used to indicate that the symbol format of the first symbol is the target symbol format, the target DCI can include slot format indication (SFI) information.

[0120] Further optionally, in the embodiments of the present application, in the case where the target DCI is used to indicate that the second symbol is cancelled, the target DCI can include cancellation indication (CI) information.

[0121] As can be seen, when the information indicated by the target DCI causes the DMRS bundling of the first transmission to change, the transmission device can adjust the DMRS pattern in the M transmission units corresponding to the first transmission, so as to avoid the case where the network side device cannot perform uplink channel estimation on the first transmission, thereby avoiding the case of affecting the delay and reliability of the transmission device sending the uplink channel, and thus the performance of the transmission device sending the channel can be improved.

[0122] Optionally, in the embodiments of the present application, the transmission device can first determine a certain DMRS pattern (for example, the target DMRS pattern in the following embodiments) in the M transmission units, and then adjust the DMRS pattern in the M transmission units based on the certain DMRS pattern.

[0123] In step 103, the transmission device transmits the M transmission units according to the adjusted DMRS pattern.

[0124] The transmission method provided by the embodiments of the present application can be used for the transmission device to receive the target DCI from the network side device, and adjust the DMRS pattern in the M transmission units corresponding to the first transmission according to the reception time of the target DCI, and transmit the M transmission units according to the adjusted DMRS pattern. When the information indicated by the target DCI causes the transmission device to change the transmission power (and / or the transmission phase) during the first transmission, the transmission device can adjust the DMRS pattern in the M transmission units corresponding to the first transmission according to the reception time of the target DCI, so as to avoid the case where the network side device cannot perform uplink channel estimation on the first transmission, thereby avoiding the case of affecting the delay and reliability of the transmission device sending the uplink channel, and thus the performance of the transmission device sending the channel can be improved.

[0125] The following will illustrate how the transmission device adjusts the DMRS pattern in the M transmission units corresponding to the first transmission.

[0126] Optionally, in the embodiments of the present application, in combination with Figure 2 For example, Figure 3As shown, step 102 above can be specifically implemented through step 102a below.

[0127] Step 102a: The transmission device adjusts the DMRS pattern in the M transmission units according to the receiving time of the target DCI using the target adjustment method.

[0128] In this application embodiment, the above-mentioned target adjustment method includes at least one of the following: deleting DMRS symbols, adding DMRS symbols, and adjusting the mapping position of DMRS on time domain resources.

[0129] Further optionally, in the embodiments of this application, the transmission device may employ the method of deleting DMRS symbols, deleting the DMRS symbols of each of the M transmission units; or, it may employ the method of deleting DMRS symbols, deleting the DMRS symbols of some of the M transmission units, in order to adjust the DMRS pattern in the M transmission units.

[0130] It should be noted that the above "adding DMRS symbols" can be understood as: regenerating DMRS symbols when a transmission unit does not include DMRS symbols; or increasing the number of DMRS symbols when a transmission unit includes DMRS symbols.

[0131] The following examples, from Examples 1 to 8, illustrate how the transmission device adjusts the DMRS patterns in the M transmission units by deleting the DMRS symbol.

[0132] In one possible implementation, the transmission device may remove Q DMRS symbols from each of the M transmission units, where Q is a positive integer.

[0133] Example 1, such as Figure 4 As shown, the transmission device can delete Q (e.g., 0) DMRS symbols from each of the M transmission units (e.g., slot1 and slot2) and use slot1 and slot2 as slots for transmissions that enable DMRS binding, thereby adjusting the DMRS pattern in slot1 and slot2.

[0134] Further optionally, in this embodiment of the application, after deleting Q DMRS symbols from each of the M transmission units, the transmission device can adjust the position of the DMRS symbols of each transmission unit after the deletion of the DMRS symbols in the time domain resources so that the DMRS symbols can be evenly distributed, thereby adjusting the DMRS pattern in the M transmission units.

[0135] Example 2, such as Figure 5As shown, the transmission device can delete Q (e.g., 1) DMRS symbols from each of the M transmission units (e.g., slot1 and slot2). That is, the transmission device can delete 1 DMRS symbol from slot1 and 1 DMRS symbol from slot2. Then, the transmission device can adjust the position of the DMRS symbol in the time domain resources of slot1 after the deletion of the DMRS symbol and the position of the DMRS symbol in the time domain resources of slot2 after the deletion of the DMRS symbol. The adjusted slot1 and the adjusted slot2 are used as the slots for the corresponding DMRS-binding transmissions.

[0136] Example 3, combined Figure 5 ,like Figure 6 As shown, the transmission device can also delete two DMRS symbols in slot1 and two DMRS symbols in slot2. Then, the transmission device can adjust the position of the DMRS symbols in slot1 and slot2 in the time domain resources after the DMRS symbols are deleted, and use the adjusted slot1 and adjusted slot2 as the corresponding slots for enabling DMRS binding transmission.

[0137] Example 4, combined Figure 5 ,like Figure 7 As shown, the transmission device can also delete 3 DMRS symbols in slot1 and 3 DMRS symbols in slot2. Then, the transmission device can adjust the position of the DMRS symbols in slot1 and slot2 in the time domain resources after the DMRS symbols are deleted, and use the adjusted slot1 and adjusted slot2 as the corresponding slots for enabling DMRS binding transmission.

[0138] In another possible implementation, the transmission device may delete T DMRS symbols from a portion of the M transmission units and delete all DMRS symbols from another portion of the M transmission units, where T is an integer.

[0139] Example 5, such as Figure 8 As shown, the transmission device can delete T (e.g., 0) DMRS symbols from slot1 in M ​​transmission units (e.g., slot1 and slot2), and delete all DMRS symbols from slot2. Furthermore, slot1 and slot2 after deleting the DMRS symbols are used as slots for corresponding DMRS-bound transmissions.

[0140] Example 6, combined Figure 8 ,like Figure 9As shown, the transmission device can also delete T (e.g., 1) DMRS symbols in slot1 and delete all DMRS symbols in slot2, and use slot1 and slot2 after deleting the DMRS symbols as slots for corresponding DMRS-bound transmissions.

[0141] It can be understood that after deleting T DMRS symbols from a portion of the M transmission units and deleting all DMRS symbols from another portion of the M transmission units, the network-side device can perform channel estimation for the other portion of transmission units through the DMRS mapped from the first portion of the transmission units. That is, the first portion of the transmission units and the other portion of the transmission units can share DMRS.

[0142] Optionally, in this embodiment of the application, the above-mentioned addition of DMRS symbols is determined by any of the following methods: network-side device indication, or higher-layer pre-configuration information of the transmission device.

[0143] The following examples, 7 and 8, illustrate how the transmission device adjusts the DMRS patterns in the M transmission units by adding DMRS symbols.

[0144] Further optionally, in this embodiment of the application, the transmission device may add DMRS symbols according to the indication information received from the network-side device to adjust the DMRS pattern in the M transmission units.

[0145] Example 7, such as Figure 10 As shown, if one of the M transmission units (e.g., slot1, slot2, and slot3) (e.g., slot2, which is the part with DMRS in the first transmission) is canceled due to information indicated by the network-side device, then slot1 and slot3 can add DMRS symbols according to the indication information received from the network-side device.

[0146] Further optionally, in this embodiment of the application, the transmission device may copy the first part of the DMRS symbol to increase the DMRS symbol, thereby adjusting the DMRS pattern in the M transmission units.

[0147] Example 8, such as Figure 11 As shown, the transmission device can copy a DMRS symbol (e.g., DMRS symbol 10) to a first part of the DMRS symbol 10 (e.g., DMRS symbol 11) to add DMRS symbol 12.

[0148] It can be understood that, in the process of the first transmission, if the DMRS symbols are increased through rate matching, a longer processing time can be required. In this way, in order to save the processing time, the DMRS symbols can be increased by copying, and the repetition of the front part of the symbols can be directly performed to save the processing time and improve the transmission performance.

[0149] The following will take example 9 as an example to illustrate how the transmission device adjusts the mapping position of the DMRS in the time domain resource and adjusts the DMRS pattern in the M transmission units.

[0150] Further optionally, in the embodiments of the present application, the transmission device can map (place) the secondary transmission information (such as a reference signal (such as DMRS) and the like) on some symbols (such as flexible symbols) in all symbols of the M transmission units, or perform the repetition of the front part of the symbols, to adjust the mapping position of the DMRS in the time domain resource.

[0151] As shown in example 9, Figure 12 The transmission device can place the secondary transmission information on some symbols (such as flexible symbol 13) in all symbols of the M transmission units, so that when the received DCI indicates to the flexible symbol 13, the transmission device can directly give up the flexible symbol 13.

[0152] It can be understood that, since the flexible symbol is easy to be indicated by the newly received DCI as another transmission function or cancellation, so as to cause the flexible symbol to be unable to be used, the transmission device can place the secondary transmission information on the flexible symbol, or perform the repetition of the front part of the symbols, so that when the newly received DCI indicates to the flexible symbol, the transmission device can directly give up the flexible symbol without performing rate matching.

[0153] As can be seen, when the transmission power changes (and / or the transmission phase changes) occur in the process of the UE performing the first transmission due to the information indicated by the target DCI, the transmission device can adopt at least one of the following adjustment modes: deleting the DMRS symbol, increasing the DMRS symbol, and adjusting the mapping position of the DMRS in the time domain resource, to adjust the DMRS pattern in the M transmission units, so that the network side device can perform uplink channel estimation on the first transmission, and thus the performance of the transmission channel of the transmission device can be improved.

[0154] The following will take an example that the transmission device first determines a certain DMRS pattern in the M transmission units, and then adjusts the DMRS pattern in the M transmission units based on the certain DMRS pattern.

[0155] Optionally, in the embodiments of the present application, the above-mentioned step 102 can be implemented by the following steps 102b and 102c.

[0156] Step 102b, the transmission device determines the target DMRS pattern in the M transmission units according to the receiving time of the target DCI.

[0157] Further optionally, in the embodiments of the present application, the transmission device can determine the DMRS pattern in the transmission unit corresponding to the transmission enabled with DMRS bundling and the DMRS pattern in the transmission unit corresponding to the transmission not enabled with DMRS bundling in the M transmission units respectively to determine the target DMRS pattern.

[0158] Optionally, in the embodiments of the present application, the above step 102b can be implemented through the following step 102b1 and step 102b2.

[0159] Step 102b1, the transmission device determines X second transmission units and Y third transmission units from the M transmission units according to the receiving time of the target DCI.

[0160] In the embodiments of the present application, X and Y are integers.

[0161] In the embodiments of the present application, the X second transmission units correspond to the transmission enabled with DMRS bundling, and the Y third transmission units correspond to the transmission not enabled with DMRS bundling. The target DMRS pattern includes a first DMRS pattern and Y second DMRS patterns.

[0162] Further optionally, in the embodiments of the present application, the M transmission units can further include Z fourth transmission units, the Z fourth transmission units correspond to the transmission without adjusting the DMRS pattern, and Z is an integer.

[0163] Illustratively, in the embodiments of the present application, in the case where X and Y are not 0, the target DMRS pattern can include X DMRS patterns, Y DMRS patterns and a third DMRS pattern, or include a DMRS pattern and Y DMRS patterns; in the case where X is 0, the target DMRS pattern can include Y second DMRS patterns and / or a third DMRS pattern; in the case where Y is 0, the target pattern can include X first DMRS patterns and / or a third DMRS pattern.

[0164] Optionally, in the embodiments of the present application, in the case where X is an integer greater than 1, the X second transmission units are X adjacent transmission units, and the X second transmission units include a target second transmission unit; the target second transmission unit is a transmission unit in the M transmission units that satisfies a first condition.

[0165] Further optionally, in the embodiments of the present application, the target second transmission unit can be the first transmission unit in the X second transmission units.

[0166] Optionally, in embodiments of the present application, the first condition comprises at least one of the following:

[0167] the time interval between the starting transmission time of the transmission unit and the receiving time of the target DCI is greater than the preset time interval;

[0168] X is an integer greater than 1.

[0169] It can be understood that the previous transmission unit of the target second transmission unit is a transmission unit whose time interval between the starting transmission time and the receiving time of the target DCI is less than the preset time interval.

[0170] It should be noted that the "starting transmission time of a transmission unit" can be understood as a time after a first time length of the starting transmission time of the transmission unit. The first time length is related to the time delay of the transmission device in transmitting a symbol (and / or the processing time delay (time) of adjusting the DMRS pattern in the M transmission units). For example, the first time length includes the time delay of the transmission device in transmitting a symbol (and / or the processing time delay (time) of adjusting the DMRS pattern in the M transmission units).

[0171] Further optionally, in embodiments of the present application, the time interval between the starting transmission time of the target second transmission unit and the receiving time of the target DCI comprises the time delay of the transmission device in transmitting a symbol and the processing time delay (time) of adjusting the DMRS pattern in the M transmission units.

[0172] Optionally, in embodiments of the present application, in the case where the enabling state of the DMRS binding of the first transmission changes, Y is a positive integer, and the Y third transmission units comprise at least one of the following:

[0173] the transmission unit whose time interval between the starting transmission time and the receiving time of the target DCI is greater than the preset time interval and does not include adjacent transmission units;

[0174] the first transmission unit;

[0175] the transmission unit whose starting transmission time is later than that of the first transmission unit.

[0176] The following will take examples 10 to 29 as examples to illustrate how the transmission device determines the X second transmission units and the Y third transmission units.

[0177] For the scenario where the symbol format of the first symbol indicated by the target DCI is the target symbol format.

[0178] Example 10, assuming that the target DCI includes SFI information, such as Figure 13As shown, M transmission units include slot1, slot2, slot3, and slot4. The SFI indicates that the symbol format of the first symbol in slot3 is the target symbol format, i.e., a flexible symbol or a downlink symbol, causing the DMRS binding enable state of the first transmission to change. If the time interval T between the start transmission time of slot1 and the reception time of the target DCI is greater than a preset time interval, the transmission device can determine X second transmission units (i.e., slot1 and slot2) based on the reception time of the target DCI. Slot1 and slot2 are adjacent transmission units and contain the target second transmission unit (i.e., slot1). Slot3 is regenerated, and Y third transmission units are determined. The Y third transmission units include: the first transmission unit (i.e., slot3) and the transmission unit (i.e., slot4) whose start transmission time is later than that of slot3. That is, slot1 and slot2 correspond to transmissions with DMRS binding enabled, and slot3 and slot4 correspond to transmissions with DMRS binding disabled. If the time interval T between the start transmission time of slot 1 and the reception time of the target DCI is less than the preset time interval, the transmission device may not adjust the DMRS pattern in slot 1, slot 2, slot 3 and slot 4, or the transmission device may not expect T to be less than the preset time interval.

[0179] Example 11, assuming the target DCI includes SFI information, combined with Figure 13 ,like Figure 14 As shown, if the time interval T between the start transmission time of slot 2 and the reception time of the target DCI is greater than a preset time interval, the transmission device can determine 0 second transmission units based on the reception time of the target DCI, regenerate slot 3, and determine Y third transmission units. The Y third transmission units include: a transmission unit whose time interval between the start transmission time and the reception time of the target DCI is greater than the preset time interval and does not include adjacent transmission units (i.e., slot 2), a first transmission unit (i.e., slot 3), and a transmission unit whose start transmission time is later than that of slot 3 (i.e., slot 4). That is, slot 2, slot 3, and slot 4 correspond to transmissions where DMRS binding is not enabled. It can be understood that the Z fourth transmission units are slot 1. The transmission device has no time to adjust the DMRS pattern in slot 1. Therefore, the transmission device does not adjust the DMRS pattern in slot 1. If the time interval T between the start transmission time of slot 2 and the reception time of the target DCI is less than the preset time interval, the transmission device may not adjust the DMRS patterns in slots 1, 2, 3 and 4, or the transmission device may not expect T to be less than the preset time interval.

[0180] Example 12, assuming the target DCI includes SFI information, combined with Figure 13 ,like Figure 15 As shown, if the time interval T between the start transmission time of slot 3 and the reception time of the target DCI is greater than a preset time interval, the transmission device can determine 0 second transmission units based on the reception time of the target DCI, regenerate slot 3, and determine Y third transmission units. These Y third transmission units include: a first transmission unit (i.e., slot 3) and a transmission unit whose start transmission time is later than that of slot 3 (i.e., slot 4). That is, slot 3 and slot 4 correspond to transmissions where DMRS binding is not enabled. It can be understood that the Z fourth transmission units are slot 1 and slot 2. The transmission device has no time to adjust the DMRS patterns in slot 1 and slot 2; therefore, the transmission device does not adjust the DMRS patterns in slot 1 and slot 2. If the time interval T between the start transmission time of slot 3 and the reception time of the target DCI is less than a preset time interval, the transmission device may not adjust the DMRS patterns in slots 1, 2, 3, and 4, or the transmission device may not expect T to be less than the preset time interval.

[0181] This is for scenarios where the target DCI is used to indicate the cancellation of the transmission of the second symbol.

[0182] Example 13, assuming the target DCI includes CI information, such as Figure 16As shown, M transmission units include slot1, slot2, slot3, and slot4. The CI indicates that no transmission is performed on the second symbol in slot3, causing the DMRS binding enable state of the first transmission to change. If the time interval T between the start transmission time of slot1 and the reception time of the target DCI is greater than a preset time interval, the transmission device can determine X second transmission units (i.e., slot1 and slot2) based on the reception time of the target DCI. Slot1 and slot2 are adjacent transmission units and contain the target second transmission unit (i.e., slot1). Slot3 is regenerated, and Y third transmission units are determined. The Y third transmission units include: a first transmission unit (i.e., slot3) and a transmission unit (i.e., slot4) whose start transmission time is later than that of slot3. That is, slot1 and slot2 correspond to transmissions with DMRS binding enabled, and slot3 and slot4 correspond to transmissions with DMRS binding disabled. If the time interval T between the start transmission time of slot 1 and the reception time of the target DCI is less than the preset time interval, the transmission device may not adjust the DMRS pattern in slot 1, slot 2, slot 3 and slot 4, or the transmission device may not expect T to be less than the preset time interval.

[0183] Example 14, assuming the target DCI includes CI information, combined with Figure 16 ,like Figure 17 As shown, if the time interval T between the start transmission time of slot 2 and the reception time of the target DCI is greater than a preset time interval, the transmission device can determine 0 second transmission units based on the reception time of the target DCI, regenerate slot 3, and determine Y third transmission units. The Y third transmission units include: a transmission unit whose time interval between the start transmission time and the reception time of the target DCI is greater than the preset time interval and does not include adjacent transmission units (i.e., slot 2), a first transmission unit (i.e., slot 3), and a transmission unit whose start transmission time is later than that of slot 3 (i.e., slot 4). That is, slot 2, slot 3, and slot 4 correspond to transmissions where DMRS binding is not enabled. It can be understood that the Z fourth transmission units are slot 1. The transmission device has no time to adjust the DMRS pattern in slot 1. Therefore, the transmission device does not adjust the DMRS pattern in slot 1. If the time interval T between the start transmission time of slot 2 and the reception time of the target DCI is less than the preset time interval, the transmission device may not adjust the DMRS patterns in slots 1, 2, 3 and 4, or the transmission device may not expect T to be less than the preset time interval.

[0184] Example 15, assuming the target DCI includes CI information, combined with Figure 16 ,like Figure 18 As shown, if the time interval T between the start transmission time of slot 3 and the reception time of the target DCI is greater than a preset time interval, the transmission device can determine 0 second transmission units based on the reception time of the target DCI, regenerate slot 3, and determine Y third transmission units. These Y third transmission units include: a first transmission unit (i.e., slot 3) and a transmission unit whose start transmission time is later than that of slot 3 (i.e., slot 4). That is, slot 3 and slot 4 correspond to transmissions where DMRS binding is not enabled. It can be understood that the Z fourth transmission units are slot 1 and slot 2. The transmission device has no time to adjust the DMRS patterns in slot 1 and slot 2; therefore, the transmission device does not adjust the DMRS patterns in slot 1 and slot 2. If the time interval T between the start transmission time of slot 3 and the reception time of the target DCI is less than a preset time interval, the transmission device may not adjust the DMRS patterns in slots 1, 2, 3, and 4, or the transmission device may not expect T to be less than the preset time interval.

[0185] The target DCI is used to indicate a scenario where, if the second condition is met, the first transmission will not be performed on the first transmission unit.

[0186] Example 16, suppose the target DCI is used to indicate the scheduling of the second transmission, such as Figure 19As shown, M transmission units include slot1, slot2, slot3, and slot4. The time domain resources of the second transmission overlap with the time domain resources of the transmission units corresponding to the first transmission (e.g., slot3 and slot4), and the priority of the second transmission is higher than that of the first transmission, causing the DMRS binding enable state of the first transmission to change. If the time interval T between the start transmission time of slot1 and the reception time of the target DCI is greater than a preset time interval, the transmission device can determine X second transmission units (i.e., slot1 and slot2) according to the reception time of the target DCI. Slot1 and slot2 are adjacent transmission units, and slot1 and slot2 contain the target second transmission unit (i.e., slot1). It can also determine Y third transmission units, which include: first transmission units (i.e., slot3 and slot4). That is, slot1 and slot2 correspond to transmissions with DMRS binding enabled, and slot3 and slot4 correspond to transmissions with DMRS binding disabled. If the time interval T between the start transmission time of slot 1 and the reception time of the target DCI is less than the preset time interval, the transmission device may not adjust the DMRS pattern in slot 1, slot 2, slot 3 and slot 4, or the transmission device may not expect T to be less than the preset time interval.

[0187] Example 17, assuming the target DCI is used to indicate the scheduling of the second transmission, combined with Figure 19 ,like Figure 20 As shown, if the time interval T between the start transmission time of slot 2 and the reception time of the target DCI is greater than a preset time interval, the transmission device can determine 0 second transmission units and Y third transmission units based on the reception time of the target DCI. These Y third transmission units include: transmission units (i.e., slot 2) where the time interval between the start transmission time and the reception time of the target DCI is greater than the preset time interval and does not include adjacent transmission units; and first transmission units (i.e., slots 3 and 4). Slots 2, 3, and 4 correspond to transmissions where DMRS binding is not enabled. It can be understood that the Z fourth transmission units are slot 1. The transmission device does not have time to adjust the DMRS pattern in slot 1, therefore, the transmission device does not adjust the DMRS pattern in slot 1. If the time interval T between the start transmission time of slot 2 and the reception time of the target DCI is less than the preset time interval, the transmission device may not adjust the DMRS patterns in slots 1, 2, 3, and 4, or the transmission device may not expect T to be less than the preset time interval.

[0188] Example 18, assuming the target DCI is used to indicate the scheduling of the second transmission, combined with Figure 19 ,likeFigure 21 As shown, if the time interval T between the starting transmission time of slot3 and the receiving time of the target DCI is greater than the preset time interval, the transmission device can determine 0 second transmission units according to the receiving time of the target DCI, and determine Y third transmission units, the Y third transmission units include: the first transmission units (i.e., slot3 and slot4), that is, slot3 and slot4 correspond to transmission without enabling DMRS binding; it can be understood that the Z fourth transmission units are slot1 and slot2, and the transmission device has no time to adjust the DMRS pattern in slot1 and the DMRS pattern in slot2, therefore, the transmission device does not adjust the DMRS pattern in slot1 and the DMRS pattern in slot2. If the time interval T between the starting transmission time of slot3 and the receiving time of the target DCI is less than the preset time interval, the transmission device can not adjust the DMRS pattern in slot1, slot2, slot3 and slot4, or the transmission device does not expect T to be less than the preset time interval.

[0189] For the scenario that the target DCI is used to indicate that the third transmission is scheduled on the first serving cell or the first carrier.

[0190] Example 19, assuming that the target DCI is used to indicate that the third transmission is scheduled on the first serving cell or the first carrier, as Figure 22 As shown, the M transmission units include slot1, slot2, slot3 and slot4, the third transmission is a downlink transmission, and the time domain resources of the downlink transmission overlap the time domain resources of the transmission units (e.g., slot3 and slot4) corresponding to the first transmission, resulting in a change in the enabling state of the DMRS binding of the first transmission, if the time interval T between the starting transmission time of slot1 and the receiving time of the target DCI is greater than the preset time interval, the transmission device can determine X second transmission units (i.e., slot1 and slot2) according to the receiving time of the target DCI, the slot1 and slot2 are adjacent transmission units, and the slot1 and slot2 contain the target second transmission unit (i.e., slot1), and determine Y third transmission units, the Y third transmission units include: the first transmission units (i.e., slot3 and slot4), that is, slot1 and slot2 correspond to transmission with DMRS binding enabled, and slot3 and slot4 correspond to transmission without DMRS binding enabled. If the time interval T between the starting transmission time of slot1 and the receiving time of the target DCI is less than the preset time interval, the transmission device can not adjust the DMRS pattern in slot1, slot2, slot3 and slot4, or the transmission device does not expect T to be less than the preset time interval.

[0191] Example 20, assuming the target DCI is used to instruct the scheduling of a third transmission on the first serving cell or the first carrier, combined with Figure 22 ,like Figure 23 As shown, if the time interval T between the start transmission time of slot 2 and the reception time of the target DCI is greater than a preset time interval, the transmission device can determine 0 second transmission units and Y third transmission units based on the reception time of the target DCI. These Y third transmission units include: transmission units (i.e., slot 2) where the time interval between the start transmission time and the reception time of the target DCI is greater than the preset time interval and does not include adjacent transmission units; and first transmission units (i.e., slots 3 and 4). Slots 2, 3, and 4 correspond to transmissions where DMRS binding is not enabled. It can be understood that the Z fourth transmission units are slot 1. The transmission device does not have time to adjust the DMRS pattern in slot 1, therefore, the transmission device does not adjust the DMRS pattern in slot 1. If the time interval T between the start transmission time of slot 2 and the reception time of the target DCI is less than the preset time interval, the transmission device may not adjust the DMRS patterns in slots 1, 2, 3, and 4, or the transmission device may not expect T to be less than the preset time interval.

[0192] Example 21, assuming the target DCI is used to indicate scheduling a third transmission on the first serving cell or the first carrier, combined with Figure 22 ,like Figure 24 As shown, if the time interval T between the start transmission time of slot 36 and the reception time of the target DCI is greater than a preset time interval, the transmission device can determine 0 second transmission units and Y third transmission units based on the reception time of the target DCI. These Y third transmission units include: first transmission units (i.e., slots 3 and 4), where slots 3 and 4 correspond to transmissions where DMRS binding is not enabled; it can be understood that the Z fourth transmission units are slots 1 and 2. The transmission device has no time to adjust the DMRS patterns in slots 1 and 2, therefore, the transmission device does not adjust the DMRS patterns in slots 1 and 2. If the time interval T between the start transmission time of slot 3 and the reception time of the target DCI is less than a preset time interval, the transmission device may not adjust the DMRS patterns in slots 1, 2, 3, and 4, or the transmission device may not expect T to be less than the preset time interval.

[0193] The target DCI is used to indicate downlink transmission between the two transmission units corresponding to the first transmission.

[0194] Example 22, such asFigure 25 As shown, M transmission units include slot1, slot2, slot4, and slot5. The target DCI is used to indicate downlink transmission between slot2 and slot4, causing a change in the DMRS binding enable state of the first transmission. If the time interval T between the start transmission time of slot1 and the reception time of the target DCI is greater than a preset time interval, the transmission device can determine X second transmission units (i.e., slot1 and slot2) based on the reception time of the target DCI. Slot1 and slot2 are adjacent transmission units, and slot1 and slot2 contain the target second transmission unit (i.e., slot1). It can also determine Y third transmission units, which include: first transmission units (i.e., slot4 and slot5), where slot1 and slot2 correspond to transmissions with DMRS binding enabled, and slot4 and slot5 correspond to transmissions with DMRS binding disabled. If the time interval T between the start transmission time of slot 1 and the reception time of the target DCI is less than the preset time interval, the transmission device may not adjust the DMRS patterns in slot 1, slot 2, slot 4 and slot 5, or the transmission device may not expect T to be less than the preset time interval.

[0195] Example 23, combined Figure 25 ,like Figure 26 As shown, if the time interval T between the start transmission time of slot 2 and the reception time of the target DCI is greater than a preset time interval, the transmission device can determine 0 second transmission units and Y third transmission units based on the reception time of the target DCI. These Y third transmission units include: transmission units (i.e., slot 2) where the time interval between the start transmission time and the reception time of the target DCI is greater than the preset time interval and does not include adjacent transmission units; and first transmission units (i.e., slots 4 and 5). That is, slots 2, 4, and 5 correspond to transmissions where DMRS binding is not enabled. It can be understood that the Z fourth transmission units are slot 1. The transmission device has no time to adjust the DMRS pattern in slot 1, therefore, the transmission device does not adjust the DMRS pattern in slot 1. If the time interval T between the start transmission time of slot 2 and the reception time of the target DCI is less than the preset time interval, the transmission device may not adjust the DMRS patterns in slots 1, 2, 4, and 5, or the transmission device may not expect T to be less than the preset time interval.

[0196] Example 24, combined Figure 25 ,like Figure 27As shown, if the time interval T between the starting transmission time of slot3 (i.e. downlink transmission) and the receiving time of the target DCI is greater than the preset time interval, the transmission device can determine 0 second transmission units and Y third transmission units according to the receiving time of the target DCI, the Y third transmission units including: the first transmission unit (i.e. slot4 and slot5), i.e. slot4 and slot5 correspond to the transmission without enabling DMRS binding. It can be understood that the Z fourth transmission units are slot1 and slot2, and the transmission device has no time to adjust the DMRS pattern in slot1 and the DMRS pattern in slot2, therefore, the transmission device does not adjust the DMRS pattern in slot1 and the DMRS pattern in slot2. If the time interval T between the starting transmission time of slot3 and the receiving time of the target DCI is less than the preset time interval, the transmission device can not adjust the DMRS pattern in slot1, slot2, slot4 and slot5, or the transmission device does not expect T to be less than the preset time interval.

[0197] For the scenario that the target DCI is used to indicate the fourth transmission or cancel the fourth transmission on the first serving cell or the first carrier.

[0198] Example 25, assuming that the target DCI is used to indicate the fourth transmission on the first serving cell (e.g. cell2) or the first carrier (e.g. carrier2), as Figure 28As shown, M transmission units include slot1, slot2, slot3, and slot4. The start time of the fourth transmission (i.e., the start time when the transmission power of the transmission device changes) matches the start time of slot3, and the end time of the fourth transmission (the end time when the transmission power of the transmission device changes) matches the end time of slot4, causing the DMRS binding enable state of the first transmission to change. If the time interval T between the start time of slot1 and the reception time of the target DCI is greater than a preset time interval, the transmission device can determine X second transmission units (i.e., slot1 and slot2) based on the reception time of the target DCI. Slot1 and slot2 are adjacent transmission units, and slot1 and slot2 contain the target second transmission unit (i.e., slot1). It can also determine Y third transmission units, which include: first transmission units (i.e., slot3 and slot4). That is, slot1 and slot2 correspond to transmissions with DMRS binding enabled, and slot3 and slot4 correspond to transmissions with DMRS binding disabled. If the time interval T between the start transmission time of slot 1 and the reception time of the target DCI is less than the preset time interval, the transmission device may not adjust the DMRS pattern in slot 1, slot 2, slot 3 and slot 4, or the transmission device may not expect T to be less than the preset time interval.

[0199] Example 26, assuming the target DCI is used to indicate a fourth transmission on the first serving cell (e.g., cell 2) or the first carrier (e.g., carrier 2), combined with Figure 28 ,like Figure 29 As shown, if the time interval T between the start transmission time of slot 2 and the reception time of the target DCI is greater than a preset time interval, the transmission device can determine 0 second transmission units and Y third transmission units based on the reception time of the target DCI. These Y third transmission units include: transmission units (i.e., slot 2) where the time interval between the start transmission time and the reception time of the target DCI is greater than the preset time interval and does not include adjacent transmission units; and first transmission units (i.e., slots 3 and 4). Slots 2, 3, and 4 correspond to transmissions where DMRS binding is not enabled. It can be understood that the Z fourth transmission units are slot 1. The transmission device does not have time to adjust the DMRS pattern in slot 1, therefore, the transmission device does not adjust the DMRS pattern in slot 1. If the time interval T between the start transmission time of slot 2 and the reception time of the target DCI is less than the preset time interval, the transmission device may not adjust the DMRS patterns in slots 1, 2, 3, and 4, or the transmission device may not expect T to be less than the preset time interval.

[0200] Example 27, assuming the target DCI is used to indicate a fourth transmission on the first serving cell or the first carrier, combined with Figure 28 ,like Figure 30 As shown, if the time interval T between the start transmission time of slot 3 and the reception time of the target DCI is greater than a preset time interval, the transmission device can determine 0 second transmission units and Y third transmission units based on the reception time of the target DCI. These Y third transmission units include: first transmission units (i.e., slots 3 and 4), where slots 3 and 4 correspond to transmissions where DMRS binding is not enabled; it can be understood that the Z fourth transmission units are slots 1 and 2. The transmission device has no time to adjust the DMRS patterns in slots 1 and 2, therefore, the transmission device does not adjust the DMRS patterns in slots 1 and 2. If the time interval T between the start transmission time of slot 3 and the reception time of the target DCI is less than a preset time interval, the transmission device may not adjust the DMRS patterns in slots 1, 2, 3, and 4, or the transmission device may not expect T to be less than the preset time interval.

[0201] Optionally, in this embodiment of the application, Y is 0 when the number of transmission units corresponding to the transmissions bound to DMRS changes.

[0202] This is for scenarios where the target DCI is used to indicate the scheduling of the fifth transmission.

[0203] Example 28, such as Figure 31 As shown, the target DCI is used to indicate the scheduling of the fifth transmission, which corresponds to slot 2. Slot 2 is bound to the transmissions scheduled by other DCIs to construct the first transmission, causing a change in the number of transmission units corresponding to the transmissions that enable DMRS binding. The transmissions scheduled by the other DCIs correspond to slot 1. If the time interval T between the start transmission time of slot 1 and the reception time of the target DCI is greater than a preset time interval, the transmission device can determine X second transmission units (i.e., slots 1 and 2) and 0 third transmission units based on the reception time of the target DCI. That is, slots 1 and 2 correspond to the transmissions that enable DMRS binding. If the time interval T between the start transmission time of slot 1 and the reception time of the target DCI is less than the preset time interval, the transmission device may not adjust the DMRS pattern in slots 1 and 2, or the transmission device may not expect T to be less than the preset time interval.

[0204] This is for scenarios where the target DCI is used to indicate the scheduling of the first transmission.

[0205] Example 29, such as Figure 32 As shown, the target DCI is used to indicate the scheduling of the first transmission, which corresponds to slot 1. Slot 1 and the PUSCH scheduled by the semi-static PDSCH are transmitted in adjacent slots. The pre-configured semi-static PUSCH includes slot 2. If the time interval T between the start transmission time of slot 1 and the reception time of the target DCI is greater than a preset time interval, the transmission device can determine X second transmission units (i.e., slot 1 and slot 2) and 0 third transmission units based on the reception time of the target DCI. That is, slot 1 and slot 2 correspond to the transmissions that enable DMRS binding. If the time interval T between the start transmission time of slot 1 and the reception time of the target DCI is less than the preset time interval, the transmission device may not adjust the DMRS pattern in slot 1 and slot 2, or the transmission device may not expect T to be less than the preset time interval.

[0206] Optionally, in the embodiments of this application, the above-mentioned preset time interval is related to at least one of the following:

[0207] The subcarrier spacing corresponding to the target DCI;

[0208] Capability information reported by the transmission device;

[0209] Does the first symbol of the first transmission contain only DMRS symbols?

[0210] Does the transmission device trigger a switching operation for the bandwidth portion of the BWP?

[0211] Whether the transmission device is connected to network-side equipment on a channel with shared spectrum;

[0212] Whether the time domain resources of the first transmission overlap with the time domain resources of other transmissions scheduled by the target DCI, and whether the transmission priority of the first transmission is higher than the transmission priority of other transmissions;

[0213] The network-side device is configured to advance the TA duration.

[0214] The radio frequency readjustment duration for frequency hopping transmission by the transmission device;

[0215] The first symbol of the first transmission and the distance between the first DMRS symbol of the first transmission;

[0216] The position of the first transmission unit in the first transmission.

[0217] In this embodiment of the application, the first transmission unit is: the transmission unit corresponding to the target DCI among the M transmission units.

[0218] Further optionally, in embodiments of the present application, the preset time interval can also be related to a time delay of the transmission device in transmitting the symbols (and a processing time delay (time) of adjusting the DMRS patterns in the M transmission units).

[0219] Step 102b2, the transmission device determines the first DMRS pattern based on the total number of symbols of the X second transmission units, and determines a respective corresponding second DMRS pattern based on the number of symbols of each third transmission unit, respectively.

[0220] In embodiments of the present application, the above target DMRS pattern includes the first DMRS pattern and Y second DMRS patterns.

[0221] Further optionally, in embodiments of the present application, the target DMRS pattern can also include a third DMRS pattern, which is a DMRS pattern in Z fourth transmission units.

[0222] It should be noted that the description of the transmission device determining the DMRS pattern based on the number of symbols can refer to the specific description in the related art, and the embodiments of the present application will not be repeated here.

[0223] Therefore, it can be seen that, since the transmission device can determine the first DMRS pattern based on the total number of symbols of the X second transmission units to take the X second transmission units as the transmission units corresponding to the transmission enabled DMRS binding, and the transmission device can determine a respective corresponding second DMRS pattern based on the number of symbols of each third transmission unit to take each third transmission unit as the transmission unit corresponding to the transmission not enabled DMRS binding, respectively, rather than taking all transmission units as the transmission units corresponding to the transmission not enabled DMRS binding, respectively, the time domain density of the DMRS symbol can be reduced, and thus the reception performance can be improved.

[0224] Step 102c, the transmission device adjusts the DMRS patterns in the M transmission units based on the target DMRS pattern.

[0225] Further optionally, in embodiments of the present application, the transmission device can adjust the DMRS patterns in the M transmission units based on the target DMRS pattern by using a target adjustment manner.

[0226] It should be noted that the description of the target adjustment manner can refer to the specific description in the above embodiments, and the embodiments of the present application will not be repeated here.

[0227] Therefore, the transmission device can determine the target DMRS pattern in the M transmission units according to the receiving time of the target DCI, then adjust the DMRS pattern in the M transmission units based on the target DMRS pattern, and does not need to adjust the DMRS pattern according to the indication of the network side device, so that the time consumption of adjusting the DMRS pattern can be reduced, and the efficiency of the transmission device in sending a channel can be improved.

[0228] It should be noted that the transmission method provided in the embodiments of the present application can be executed by the transmission device, or a control module in the transmission device for executing the transmission method. In the embodiments of the present application, the transmission device is taken as an example to illustrate the transmission method provided in the embodiments of the present application.
