Further optionally, in this embodiment of the present application, the transmission apparatus may delete the DMRS symbol, and delete the DMRS symbol of each of the M transmission elements; alternatively, the DMRS patterns in the M transmission elements may be adjusted by deleting DMRS symbols and deleting DMRS symbols of some of the M transmission elements.
It should be noted that the "adding DMRS symbols" may be understood as follows: regenerating the DMRS symbol when the DMRS symbol is not included in one transmission unit; alternatively, in the case where DMRS symbols are included in one transmission unit, the number of DMRS symbols is increased.
In the following, taking examples 1 to 8 as examples, how a transmission apparatus adjusts DMRS patterns in M transmission elements by using DMRS symbol deletion will be described.
In one possible implementation, the transmission apparatus may delete Q DMRS symbols for each of the M transmission elements, Q being a positive integer.
Example 1, as shown in fig. 4, a transmission apparatus may delete Q (e.g., 0) DMRS symbols for each of M transmission elements (e.g., slot1 and slot2), and use slot1 and slot2 as slots corresponding to DMRS bundling-enabled transmission to adjust DMRS patterns in slot1 and slot 2.
Further optionally, in this embodiment, after deleting the Q DMRS symbols of each of the M transmission elements, the transmission apparatus may adjust a position of the DMRS symbol of each transmission element after deleting the DMRS symbol on the time domain resource, so that the DMRS symbols may be evenly distributed to adjust the DMRS patterns in the M transmission elements.
Example 2, as shown in fig. 5, the transmission apparatus may delete Q (e.g., 1) DMRS symbols of each of M transmission elements (e.g., slot1 and slot2), that is, the transmission apparatus may delete 1 DMRS symbol of slot1 and delete 1 DMRS symbol of slot2, and then the transmission apparatus may adjust a position of the DMRS symbol of slot1 after deleting the DMRS symbol on the time domain resource and a position of the DMRS symbol of slot2 after deleting the DMRS symbol on the time domain resource, and use the adjusted slot1 and the adjusted slot2 as slots corresponding to transmission enabling DMRS bundling.
Example 3, in conjunction with fig. 5, as shown in fig. 6, the transmission apparatus may further delete 2 DMRS symbols of slot1, and delete 2 DMRS symbols of slot2, and then the transmission apparatus may adjust a position of the DMRS symbol of slot1 after the DMRS symbol is deleted on the time domain resource, and a position of the DMRS symbol of slot2 after the DMRS symbol is deleted on the time domain resource, and use the adjusted slot1 and the adjusted slot2 as slots corresponding to DMRS bundling-enabled transmission.
Example 4, in conjunction with fig. 5, as shown in fig. 7, the transmission apparatus may further delete 3 DMRS symbols of slot1, and delete 3 DMRS symbols of slot2, and then the transmission apparatus may adjust a position of the DMRS symbol of slot1 after the DMRS symbol is deleted on the time domain resource, and a position of the DMRS symbol of slot2 after the DMRS symbol is deleted on the time domain resource, and use the adjusted slot1 and the adjusted slot2 as slots corresponding to DMRS bundling-enabled transmission.
In another possible implementation manner, the transmission apparatus may delete T DMRS symbols of a part of the M transmission elements, and delete all DMRS symbols of another part of the M transmission elements, where T is an integer.
Example 5, as shown in fig. 8, the transmission apparatus may delete T (e.g., 0) DMRS symbols of slot1 in M transmission elements (e.g., slot1 and slot2), delete all DMRS symbols of slot2, and use slot1 after the DMRS symbols are deleted and slot2 after the DMRS symbols are deleted as slots corresponding to DMRS bundling-enabled transmission.
Example 6, in conjunction with fig. 8, as shown in fig. 9, the transmission apparatus may further delete T (e.g., 1) DMRS symbols of slot1, delete all DMRS symbols of slot2, and take slot1 after the DMRS symbols are deleted and slot2 after the DMRS symbols are deleted as slots corresponding to DMRS bonding-enabled transmission.
It can be understood that, after deleting T DMRS symbols of a part of M transmission units and deleting all DMRS symbols of another part of the M transmission units, the network side device may perform channel estimation on the another part of the transmission units through the DMRS mapped by the part of the transmission units, that is, the part of the transmission units and the another part of the transmission units may share (sharing) the DMRS.
Optionally, in this embodiment of the present application, the DMRS symbol is determined by any one of the following manners: and the network side equipment indicates and transmits the high-level pre-configuration information of the device.
In the following, taking example 7 and example 8 as examples, how a transmission apparatus adjusts DMRS patterns in M transmission elements by adding DMRS symbols will be described.
Further optionally, in this embodiment of the application, the transmission apparatus may add the DMRS symbol according to the indication information received from the network side device, so as to adjust the DMRS patterns in the M transmission elements.
Example 7, as shown in fig. 10, if one transmission element (e.g., slot2, that is, a portion in the first transmission where there is a DMRS) of M transmission elements (e.g., slot1, slot2, and slot3) is cancelled due to information indicated by the network side device, then slot1 and slot3 may increase a DMRS symbol according to indication information received from the network side device.
Further optionally, in this embodiment of the present application, the transmission apparatus may copy the front part of the DMRS symbols to add the DMRS symbols, so as to adjust the DMRS patterns in the M transmission elements.
Example 8, as shown in fig. 11, a transmission apparatus may copy a DMRS symbol (e.g., DMRS symbol 10) as a front part symbol of the DMRS symbol 10 (e.g., DMRS symbol 11) to add a DMRS symbol 12.
It can be understood that, in the first transmission process, if DMRS symbols are added through rate matching (rate matching), a long processing time may be required. In this way, in order to save processing time, DMRS symbols may be added by duplication, and the front part symbols may be directly repeated, so as to save processing time and improve transmission performance.
In the following, taking example 9 as an example, how a transmission apparatus adjusts DMRS patterns in M transmission elements by adjusting the mapping positions of DMRSs on time-domain resources will be described.
Further alternatively, in this embodiment, the transmission apparatus may map (place) secondary transmission information (e.g., a reference signal (e.g., DMRS), etc.) on some symbols (e.g., flexible symbols) in all symbols of the M transmission elements, or perform repetition of a front part symbol to adjust a mapping position of the DMRS on the time domain resource.
Example 9, as shown in fig. 12, the transmission apparatus may place secondary transmission information on some symbols (e.g., flexible symbol 13) among all symbols of the M transmission units, so that the transmission apparatus may directly discard the flexible symbol 13 when the received DCI indicates the flexible symbol 13.
It is to be appreciated that, since a flexible symbol is easily indicated by a newly received DCI as another transmission or cancelled, so that the flexible symbol cannot be used, the transmission apparatus may place secondary transmission information on the flexible symbol or perform repetition of a front part symbol, so that when the newly received DCI indicates the flexible symbol, the transmission apparatus may directly discard the flexible symbol without performing rate matching.
As can be seen from this, when the information indicated by the target DCI causes a change in transmission power (and/or a change in transmission phase) during the first transmission performed by the UE, the transmission apparatus may adjust the DMRS patterns in the M transmission elements by using at least one of an adjustment method of deleting a DMRS symbol, adding a DMRS symbol, and adjusting a mapping position of the DMRS on the time domain resource, so that the network side device may perform uplink channel estimation on the first transmission, and therefore, the performance of the transmission apparatus for transmitting a channel may be improved.
In the following, a transmission apparatus will be described as an example, which determines a certain DMRS pattern in M transmission cells first, and then adjusts the DMRS pattern in the M transmission cells based on the certain DMRS pattern.
Alternatively, in this embodiment of the application, the step 102 may be specifically implemented by the following step 102b and step 102 c.
And step 102b, the transmission device determines the target DMRS patterns in the M transmission units according to the receiving time of the target DCI.
Further optionally, in this embodiment of the present application, the transmission apparatus may determine DMRS patterns in transmission units corresponding to DMRS bundling-enabled transmission and DMRS patterns in transmission units corresponding to DMRS bundling-disabled transmission in the M transmission units, respectively, to determine the target DMRS patterns.
Alternatively, in this embodiment of the application, the step 102b may be specifically realized by the following step 102b1 and step 102b 2.
Step 102b1, the transmission apparatus determines X second transmission units and Y third transmission units from M transmission units according to the receiving time of the target DCI.
In the embodiment of the present application, X, Y are all integers.
In this embodiment, the X second transmission units enable DMRS binding transmission correspondingly; the Y third transmission units correspond to transmission in which DMRS binding is not enabled. The target DMRS pattern includes: a first DMRS pattern and Y second DMRS patterns.
Further optionally, in this embodiment of the application, the M transmission units may further include Z fourth transmission units, where the Z fourth transmission units correspond to transmission of the unadjusted DMRS pattern, and Z is an integer.
Exemplarily, in this embodiment of the present application, in case that none of X, Y is 0, the target DMRS pattern may include X, Y, and third DMRS patterns, or include a DMRS pattern and Y DMRS patterns; in the case where X is 0, the target DMRS pattern may include Y second DMRS patterns, and/or a third DMRS pattern; in the case where Y is 0, the target pattern may include X first DMRS patterns, and/or a third DMRS pattern.
Optionally, in this embodiment of the application, when X is an integer greater than 1, the X second transmission units are X adjacent transmission units, and a target second transmission unit is included in the X second transmission units; the target second transmission unit is: among the M transmission units, a transmission unit satisfying the first condition.
Further optionally, in this embodiment of the application, the target second transmission unit may specifically be a first transmission unit in the X second transmission units.
Optionally, in an embodiment of the present application, the first condition includes at least one of:
the time interval between the initial transmission moment of the transmission unit and the receiving moment of the target DCI is greater than the preset time interval;
x is an integer greater than 1.
It will be appreciated that the previous transmission unit of the target second transmission unit is: and the time interval between the starting transmission moment and the receiving moment of the target DCI is smaller than the preset time interval.
It should be noted that "the starting transmission time of one transmission unit" can be understood as: a time after the first duration of the start transmission time of the one transmission unit. Wherein the first duration is related to a time delay for transmission of the symbol by the transmission apparatus (and/or adjustment of processing time delay (time) of the DMRS patterns in the M transmission elements). For example, the first duration includes: a time delay for transmission of symbols by a transmission apparatus (and/or adjustment of processing time delay (time) of DMRS patterns in M transmission elements).
Further optionally, in this embodiment of the application, a time interval between the starting transmission time of the target second transmission unit and the receiving time of the target DCI includes: a time delay for the transmission of symbols by the transmission apparatus, and a processing time delay (time) for adjusting the DMRS patterns in the M transmission cells.
Optionally, in this embodiment of the application, when the enable state of the DMRS bundling for the first transmission is changed, Y is a positive integer, and the Y third transmission units include at least one of the following:
a time interval between the initial transmission time and the receiving time of the target DCI is greater than a preset time interval and does not include a transmission unit of an adjacent transmission unit;
a first transmission unit;
the start transmission time is later than the transmission unit of the first transmission unit.
How the transmission device determines X second transmission units and Y third transmission units will be described below by taking examples 10 to 29 as examples.
And aiming at the target DCI, indicating that the symbol format of the first symbol is the scene of the target symbol format.
Example 10, assuming that the target DCI includes SFI information, as shown in fig. 13, M transmission elements include slot1, slot2, slot3, and slot4, where the SFI indicates that a symbol format of a first symbol in slot3 is a target symbol format, that is, a flexible symbol or a downlink symbol, resulting in a change in an enable state of DMRS binding for first transmission, and if a time interval T between an initial transmission time of slot1 and a reception time of the target DCI is greater than a preset time interval, the transmission apparatus may determine, according to the reception time of the target DCI, X second transmission elements (i.e., slot1 and slot2), where slot1 and slot2 are adjacent transmission elements, and slot1 and slot2 include a target second transmission element (i.e., slot1), and regenerate slot3, and determine Y third transmission elements, where the Y third transmission elements include: a first transmission unit (i.e., slot3) and a transmission unit (i.e., slot4) whose initial transmission time is later than that of slot3, i.e., slot1 and slot2 correspond to transmission in which DMRS binding is enabled, and slot3 and slot4 correspond to transmission in which DMRS binding is not enabled. If the time interval T between the starting transmission time of slot1 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 slot1, slot2, slot3, and slot4, or the transmission device does not expect T to be less than the preset time interval.
Example 11, assuming that the target DCI includes SFI information, referring to fig. 13, as shown in fig. 14, if a time interval T between a starting transmission time of a slot2 and a receiving time of the target DCI is greater than a preset time interval, so that a transmission device may determine 0 second transmission units and regenerate slots 3 according to the receiving time of the target DCI, and determine Y third transmission units, where the Y third transmission units include: a time interval between the initial transmission time and the receiving time of the target DCI is greater than a preset time interval, and a transmission unit (namely, slot2) which does not include an adjacent transmission unit, a first transmission unit (namely, slot3) and a transmission unit (namely, slot4) of which the initial transmission time is later than the slot3 are included, namely, the slots 2, 3 and 4 correspond to transmission of the non-enabled DMRS bindings; it can be understood that the Z fourth transmission elements are slots 1, and the transmission apparatus has not time to adjust the DMRS pattern in slot1, and therefore, the transmission apparatus does not adjust the DMRS pattern in this slot 1. If the time interval T between the starting transmission time of slot2 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 slot1, slot2, slot3, and slot4, or the transmission device does not expect T to be less than the preset time interval.
Example 12, assuming that the target DCI includes SFI information, referring to fig. 13, as shown in fig. 15, if a time interval T between a starting transmission time of a slot3 and a receiving time of the target DCI is greater than a preset time interval, so that a transmission device may determine 0 second transmission units and regenerate slots 3 according to the receiving time of the target DCI, and determine Y third transmission units, where the Y third transmission units include: a first transmission unit (i.e., slot3) and a transmission unit (i.e., slot4) with an initial transmission time later than that of the slot3, that is, the slots 3 and 4 correspond to transmission without enabling DMRS binding; it can be understood that the Z fourth transmission elements are slot1 and slot2, and the transmission apparatus has not time to adjust the DMRS pattern in slot1 and the DMRS pattern in slot2, and therefore, the transmission apparatus does not adjust the DMRS pattern in slot1 and the DMRS pattern in slot 2. If the time interval T between the start transmission time of the slot3 and the reception time of the target DCI is smaller than the preset time interval, the transmission apparatus may not adjust the DMRS patterns in the slot1, slot2, slot3, and slot4, or the transmission apparatus does not expect T to be smaller than the preset time interval.
A scenario for a target DCI to indicate cancellation of transmission of a second symbol.
Example 13, assuming that the target DCI includes CI information, as shown in fig. 16, M transmission units include slot1, slot2, slot3, and slot4, where the CI indicates that no transmission is performed on a second symbol in slot3, resulting in a change in an enable state of DMRS bundling for a first transmission, and if a time interval T between a starting transmission time of slot1 and a receiving time of the target DCI is greater than a preset time interval, the transmission apparatus may determine, according to the receiving time of the target DCI, X second transmission units (i.e., slot1 and slot2), where slot1 and slot2 are adjacent transmission units, and the slot1 and slot2 include the target second transmission unit (i.e., slot1), and regenerate slot3, and determine Y third transmission units, where the Y third transmission units include: a first transmission unit (i.e., slot3) and a transmission unit (i.e., slot4) whose initial transmission time is later than that of slot3, i.e., slot1 and slot2 correspond to transmission in which DMRS binding is enabled, and slot3 and slot4 correspond to transmission in which DMRS binding is not enabled. If the time interval T between the starting transmission time of slot1 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 slot1, slot2, slot3, and slot4, or the transmission device does not expect T to be less than the preset time interval.
Example 14, assuming that the target DCI includes CI information, referring to fig. 16, as shown in fig. 17, if a time interval T between a starting transmission time of a slot2 and a receiving time of the target DCI is greater than a preset time interval, so that the transmission apparatus may determine 0 second transmission units and regenerate a slot3 according to the receiving time of the target DCI, and determine Y third transmission units, where the Y third transmission units include: a time interval between the initial transmission time and the receiving time of the target DCI is greater than a preset time interval, and a transmission unit (namely, slot2) which does not include an adjacent transmission unit, a first transmission unit (namely, slot3) and a transmission unit (namely, slot4) of which the initial transmission time is later than the slot3 are included, namely, the slots 2, 3 and 4 correspond to transmission of the non-enabled DMRS bindings; it can be understood that the Z fourth transmission elements are slots 1, and the transmission apparatus has not time to adjust the DMRS pattern in slot1, and therefore, the transmission apparatus does not adjust the DMRS pattern in this slot 1. If the time interval T between the starting transmission time of slot2 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 slot1, slot2, slot3, and slot4, or the transmission device does not expect T to be less than the preset time interval.
Example 15, assuming that the target DCI includes CI information, with reference to fig. 16, as shown in fig. 18, if a time interval T between a starting transmission time of a slot3 and a receiving time of the target DCI is greater than a preset time interval, so that the transmission apparatus may determine 0 second transmission units and regenerate slots 3 according to the receiving time of the target DCI, and determine Y third transmission units, where the Y third transmission units include: a first transmission unit (i.e., slot3) and a transmission unit (i.e., slot4) with an initial transmission time later than that of the slot3, that is, the slots 3 and 4 correspond to transmission without enabling DMRS binding; it can be understood that the Z fourth transmission elements are slot1 and slot2, and the transmission apparatus has not time to adjust the DMRS pattern in slot1 and the DMRS pattern in slot2, and therefore, the transmission apparatus does not adjust the DMRS pattern in slot1 and the DMRS pattern in slot 2. If the time interval T between the starting transmission time of slot3 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 slot1, slot2, slot3, and slot4, or the transmission device does not expect T to be less than the preset time interval.
And indicating a scenario that the first transmission is not performed on the first transmission unit if the second condition is satisfied for the target DCI.
Example 16, assuming that the target DCI is used to instruct scheduling of a second transmission, as shown in fig. 19, M transmission units include slot1, slot2, slot3, and slot4, a time domain resource of the second transmission overlaps a time domain resource of a transmission unit (e.g., slot3 and slot4) corresponding to the first transmission, and a priority of the second transmission is higher than a priority of the first transmission, which results in a change in an enable state of DMRS binding for the first transmission, and if a time interval T between a start transmission time of slot1 and a reception time of the target DCI is greater than a preset time interval, the transmission apparatus may determine, according to the reception time of the target DCI, X second transmission units (i.e., slot1 and slot2), where the slot1 and the slot2 are adjacent transmission units, the slot1 and the slot2 include the target second transmission unit (i.e., slot1), and determine Y third transmission units, where Y third transmission units include: the first transmission units (i.e., slot3 and slot4), that is, slot1 and slot2, correspond to DMRS binding enabled transmission, and slot3 and slot4 correspond to DMRS binding disabled transmission. If the time interval T between the starting transmission time of slot1 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 slot1, slot2, slot3, and slot4, or the transmission device does not expect T to be less than the preset time interval.
Example 17, assuming that the target DCI is used to instruct scheduling of the second transmission, referring to fig. 19, as shown in fig. 20, if a time interval T between a starting transmission time of a slot2 and a receiving time of the target DCI is greater than a preset time interval, a transmission device may determine 0 second transmission units and determine Y third transmission units according to the receiving time of the target DCI, where the Y third transmission units include: the time interval between the initial transmission time and the receiving time of the target DCI is greater than a preset time interval, and the transmission unit (namely, slot2) and the first transmission unit (namely, slot3 and slot4) which do not comprise the adjacent transmission unit, namely, slot2, slot3 and slot4 correspond to transmission which does not enable DMRS binding; it can be understood that the Z fourth transmission elements are slots 1, and the transmission apparatus has not time to adjust the DMRS pattern in slot1, and therefore, the transmission apparatus does not adjust the DMRS pattern in this slot 1. If the time interval T between the starting transmission time of slot2 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 slot1, slot2, slot3, and slot4, or the transmission device does not expect T to be less than the preset time interval.
Example 18, assuming that the target DCI is used to instruct scheduling of the second transmission, referring to fig. 19, as shown in fig. 21, if a time interval T between a starting transmission time of a slot3 and a receiving time of the target DCI is greater than a preset time interval, so that the transmission apparatus may determine 0 second transmission units and Y third transmission units according to the receiving time of the target DCI, where the Y third transmission units include: first transmission units (namely, slots 3 and 4), namely slots 3 and slots 4 correspond to transmission without DMRS binding enabled; it can be understood that the Z fourth transmission elements are slot1 and slot2, and the transmission apparatus has not time to adjust the DMRS pattern in slot1 and the DMRS pattern in slot2, and therefore, the transmission apparatus does not adjust the DMRS pattern in slot1 and the DMRS pattern in slot 2. If the time interval T between the start transmission time of the slot3 and the reception time of the target DCI is smaller than the preset time interval, the transmission apparatus may not adjust the DMRS patterns in the slot1, slot2, slot3, and slot4, or the transmission apparatus does not expect T to be smaller than the preset time interval.
A scenario for a target DCI to indicate that a third transmission is scheduled on a first serving cell or a first carrier.
Example 19, assuming that the target DCI is used to indicate that a third transmission is scheduled on the first serving cell or the first carrier, as shown in fig. 22, where M transmission units include a slot1, a slot2, a slot3, and a slot4, the third transmission is downlink transmission, and a time domain resource of the downlink transmission overlaps a time domain resource of a transmission unit (e.g., a slot3 and a slot4) corresponding to the first transmission, resulting in a change in an enable state of DMRS bundling for the first transmission, and if a time interval T between a starting transmission time of the slot1 and a receiving time of the target DCI is greater than a preset time interval, the transmission apparatus may determine, according to the receiving time of the target DCI, X second transmission units (i.e., a slot1 and a slot2), where the slot1 and the slot2 are adjacent transmission units, and the slot1 and the slot2 include the target second transmission unit (i.e., a slot1), and determine Y third transmission units include Y third transmission units: first transmission units (i.e., slots 3 and 4), that is, slots 1 and 2 correspond to transmission in which DMRS binding is enabled, and slots 3 and 4 correspond to transmission in which DMRS binding is not enabled. If the time interval T between the start transmission time of the slot1 and the reception time of the target DCI is smaller than the preset time interval, the transmission apparatus may not adjust the DMRS patterns in the slot1, slot2, slot3, and slot4, or the transmission apparatus does not expect T to be smaller than the preset time interval.
Example 20, assuming that the target DCI is used to instruct to schedule a third transmission on the first serving cell or the first carrier, referring to fig. 22, as shown in fig. 23, if a time interval T between a starting transmission time of a slot2 and a receiving time of the target DCI is greater than a preset time interval, the transmission apparatus may determine 0 second transmission units and determine Y third transmission units according to the receiving time of the target DCI, where the Y third transmission units include: the time interval between the initial transmission time and the receiving time of the target DCI is greater than a preset time interval, and the transmission unit (namely, slot2) and the first transmission unit (namely, slot3 and slot4) which do not comprise the adjacent transmission unit, namely, slot2, slot3 and slot4 correspond to transmission which does not enable DMRS binding; it can be understood that the Z fourth transmission elements are slots 1, and the transmission apparatus has not time to adjust the DMRS pattern in slot1, and therefore, the transmission apparatus does not adjust the DMRS pattern in this slot 1. If the time interval T between the start transmission time of the slot2 and the reception time of the target DCI is smaller than the preset time interval, the transmission apparatus may not adjust the DMRS patterns in the slot1, slot2, slot3, and slot4, or the transmission apparatus does not expect T to be smaller than the preset time interval.

If the time interval T between the starting transmission time of slot3 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 slot1, slot2, slot3, and slot4, or the transmission device does not expect T to be less than the preset time interval.
And the target DCI is used for indicating downlink transmission between two transmission units corresponding to the first transmission.
Example 22, as shown in fig. 25, the M transmission units include a slot1, a slot2, a slot4, and a slot5, where the target DCI is used to indicate that downlink transmission is performed between the slot2 and the slot4, which results in a change in an enable state of DMRS binding for first transmission, and if a time interval T between an initial transmission time of the slot1 and a reception time of the target DCI is greater than a preset time interval, the transmission apparatus may determine, according to the reception time of the target DCI, X second transmission units (i.e., slot1 and slot2), where the slot1 and the slot2 are adjacent transmission units, and the slot1 and the slot2 include a target second transmission unit (i.e., slot1), and determine Y third transmission units, where the Y third transmission units include: first transmission units (i.e., slots 4 and 5), that is, slots 1 and 2 correspond to transmission in which DMRS binding is enabled, and slots 4 and 5 correspond to transmission in which DMRS binding is not enabled. If the time interval T between the starting transmission time of slot1 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 slot1, slot2, slot4, and slot5, or the transmission device does not expect T to be less than the preset time interval.
Example 23, with reference to fig. 25, as shown in fig. 26, if a time interval T between a starting transmission time of slot2 and a receiving time of target DCI is greater than a preset time interval, a transmission device may determine 0 second transmission units and determine Y third transmission units according to the receiving time of the target DCI, where the Y third transmission units include: the time interval between the initial transmission time and the receiving time of the target DCI is greater than a preset time interval, and the transmission unit (namely, slot2) and the first transmission unit (namely, slot4 and slot5) which do not comprise the adjacent transmission unit, namely, slot2, slot4 and slot5 correspond to transmission which does not enable DMRS binding; it can be understood that the Z fourth transmission elements are slots 1, and the transmission apparatus has not time to adjust the DMRS pattern in slot1, and therefore, the transmission apparatus does not adjust the DMRS pattern in this slot 1. If the time interval T between the starting transmission time of slot2 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 slot1, slot2, slot4, and slot5, or the transmission device does not expect T to be less than the preset time interval.
Example 24, referring to fig. 25, as shown in fig. 27, if a time interval T between a starting transmission time of slot3 (i.e., downlink transmission) and a receiving time of target DCI is greater than a preset time interval, so that the transmission apparatus may determine 0 second transmission units and Y third transmission units according to the receiving time of the target DCI, where the Y third transmission units include: first transmission units (namely, slots 4 and 5), namely slots 4 and slots 5 correspond to transmission without DMRS binding enabled; it can be understood that the Z fourth transmission elements are slot1 and slot2, and the transmission apparatus has no time to adjust the DMRS pattern in slot1 and the DMRS pattern in this slot2, and therefore, the transmission apparatus does not adjust the DMRS pattern in this slot1 and the DMRS pattern in this slot 2.

If the time interval T between the starting transmission time of slot1 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 slot1, slot2, slot3, and slot4, or the transmission device does not expect T to be less than the preset time interval.

If the time interval T between the starting transmission time of slot2 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 slot1, slot2, slot3, and slot4, or the transmission device does not expect T to be less than the preset time interval.

If the time interval T between the starting transmission time of slot1 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 slot1 and slot2, or the transmission device does not expect T to be less than the preset time interval.
