Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication technology, and specifically discloses a reference signal position determination method, a reference signal indication method, and related products. BACKGROUND

[0002] In a new radio (NR) system, a terminal device and a network device can perform multiple repetition transmissions in an uplink or downlink transmission process, that is, the same information is transmitted on the multiple repetitions. The sending end needs to send one or more reference signals (RSs) on the time domain resources corresponding to each repetition, so that the receiving end can estimate and demodulate the information transmitted by the sending end on the repetition.

[0003] In the case of channel evolution, the terminal device and the network device can use fewer reference signals for repeated transmission. That is, no RS is sent on the time domain resources corresponding to some repetitions. Because of channel evolution, the estimation corresponding to the repetition can be achieved through the RSs sent on the time domain resources corresponding to the previous repetitions.

[0004] However, using fewer reference signals for repeated transmission changes the correspondence between the RSs and the repetitions. How the network device indicates the positions of the RSs and how the terminal device determines the positions of the RSs are still in the blank stage. SUMMARY

[0005] The present application provides a reference signal position determination method, a reference signal indication method, and related products. In the process of transmission through fewer reference signals, it can be accurately determined which repetition transmission resources carry demodulation reference signals and which repetition transmission resources do not carry demodulation reference signals, thereby filling the blank of the prior art.

[0006] In a first aspect, an embodiment of the present application provides a reference signal position determination method. The execution subject of the method can be a terminal device or a chip applied in the terminal device. Hereinafter, the execution subject is taken as an example for description.

[0007] determining at least one first repetition transmission resource carrying a reference signal in at least two repetition transmission resources, wherein there is a second repetition transmission resource not carrying a reference signal in the at least two repetition transmission resources;

[0008] receive repetitions of reference signals and downlink channels on the at least one first repetition transmission resource, receive repetitions of the downlink channels on the second repetition transmission resource, or transmit repetitions of reference signals and uplink channels on the at least one first repetition transmission resource, transmit repetitions of the uplink channels on the second repetition transmission resource.

[0009] It can be seen that in the embodiments of the present application, the terminal device can perform repetition transmission through fewer reference signals in the process of repetition transmission, and in this transmission mode, it can be accurately determined which repetition transmission resources carry reference signals and which repetition transmission resources do not carry reference signals, which makes up for the blank in the prior art. In addition, fewer reference signals are used for repetition transmission, which can save a part of time domain resources compared with the existing repetition transmission mode, and the saved time domain resources can be used for transmitting data, thereby improving the communication efficiency with the network device.

[0010] In a second aspect, the present application provides a method for determining the position of a reference signal. The execution subject of the method can be a terminal device or a chip applied in the terminal device. Hereinafter, the execution subject is taken as an example for description. The method comprises:

[0011] determining at least one first repetition transmission resource carrying reference signals in at least two repetition transmission resources, wherein there is a second repetition transmission resource carrying reference signals in the at least two repetition transmission resources, and the number of repetition transmission resources for carrying reference signals in each first repetition transmission resource in the at least one first repetition transmission resource is more than the number of repetition transmission resources for carrying reference signals in the second repetition transmission resource; that is, relatively more reference signals are carried on the first repetition transmission resource, and relatively fewer reference signals are carried on the second repetition transmission resource;

[0012] receive repetitions of reference signals and downlink channels on the at least one first repetition transmission resource, receive repetitions of the downlink channels on the second repetition transmission resource, or transmit repetitions of reference signals and uplink channels on the at least one first repetition transmission resource, transmit repetitions of the uplink channels on the second repetition transmission resource.

[0013] It can be seen that, in the embodiments of the present application, relatively less resources are used to carry reference signals on some repetition transmission resources in the process of repetition transmission, and in this transmission mode, it can be accurately determined which repetition transmission resources carry relatively more reference signals and which repetition transmission resources carry relatively less reference signals, which fills the gap in the prior art. In addition, compared with the existing repetition transmission mode, relatively less resources are used to carry reference signals on some repetition transmission resources for repetition transmission, and a part of resources are saved on these repetition transmission resources for data transmission, thereby improving the communication efficiency with the network device.

[0014] In combination with the first aspect and the second aspect, in some possible implementation manners, before determining the at least one first repetition transmission resource in which the reference signals are carried from the at least two repetition transmission resources, the method further includes:

[0015] receiving the number of the at least two repetition transmission resources and the number of the at least one first repetition transmission resource sent by the network device;

[0016] The determining the at least one first repetition transmission resource in which the reference signals are carried from the at least two repetition transmission resources includes:

[0017] determining the position of the at least one first repetition transmission resource in the at least two repetition transmission resources according to the number of the at least two repetition transmission resources and the number of the at least one first repetition transmission resource.

[0018] It can be seen that, in the embodiments, the terminal device can determine the position of the first repetition transmission resource according to the number of the at least two repetition transmission resources and the number of the at least one first repetition transmission resource sent by the network device. Therefore, the terminal device can determine the position of the first repetition transmission resource in a more flexible manner.

[0019] In combination with the first aspect and the second aspect, in some possible implementation manners, the determining the position of the at least one first repetition transmission resource in the at least two repetition transmission resources according to the number of the at least two repetition transmission resources and the number of the at least one first repetition transmission resource includes:

[0020] determining the interval between any two adjacent first repetition transmission resources in the at least one first repetition transmission resource according to the number of the at least two repetition transmission resources and the number of the at least one first repetition transmission resource;

[0021] determine the position of the at least one first repeated transmission resource in the at least two repeated transmission resources according to the interval between any two adjacent first repeated transmission resources, wherein a first repeated transmission resource in the at least two repeated transmission resources carries a demodulation reference signal.

[0022] It can be seen that in the embodiment, the terminal device can directly determine the interval between any two adjacent first repeated transmission resources according to the number of the two repeated transmission resources and the number of the at least one first repeated transmission resource, without considering the problem of uneven distribution of repeated transmission resources at the time domain edge position of the first transmission resource, improving the efficiency of determining the position of the first repeated transmission resource, and further improving the efficiency of repeated transmission.

[0023] In combination with the first aspect and the second aspect, in some possible implementation manners, the at least one first repeated transmission resource includes the first m1 first repeated transmission resources and the last m2 first repeated transmission resources.

[0024] The determining the position of the at least one first repeated transmission resource in the at least two repeated transmission resources according to the number of the at least two repeated transmission resources and the number of the at least one first repeated transmission resource includes:

[0025] determining the position of the first m1 first repeated transmission resources in the at least two repeated transmission resources and the position of the last m2 first repeated transmission resources in the at least two repeated transmission resources according to the number of the at least two repeated transmission resources and the number of the at least one first repeated transmission resource respectively, wherein a first repeated transmission resource in the at least two repeated transmission resources carries a demodulation reference signal;

[0026] wherein a first interval between any two adjacent first repeated transmission resources in the first m1 first repeated transmission resources is different from a second interval between any two adjacent first repeated transmission resources in the last m2 first repeated transmission resources, and an interval between a last first repeated transmission resource in the first m1 first repeated transmission resources and a first first repeated transmission resource in the last m2 first repeated transmission resources is the first interval.

[0027] It can be seen that in the embodiment, the terminal device considers the problem of uneven distribution of repeated transmission resources at the time domain edge position of the first transmission resource, and can split the first repeated transmission resource into two parts in advance, so that the distribution of the first repeated transmission resource is more uniform, and the estimation of the channel is more accurate and reasonable.

[0028] With reference to the first aspect and the second aspect, in some possible implementation manners, before determining the at least one first repetition transmission resource carrying the reference signal from the at least two repetition transmission resources, the method further includes:

[0029] receiving the quantity of the at least two repetition transmission resources and the interval between the nominal adjacent first repetition transmission resources sent by the network device;

[0030] The determining the at least one first repetition transmission resource carrying the reference signal from the at least two repetition transmission resources includes:

[0031] determining the position of the at least one first repetition transmission resource in the at least two repetition transmission resources according to the quantity of the at least two repetition transmission resources and the interval between the nominal adjacent first repetition transmission resources.

[0032] It can be seen that, in this embodiment, the terminal device can determine the position of the first repetition transmission resource according to the quantity of the at least two repetition transmission resources and the interval between the nominal adjacent first repetition transmission resources sent by the network device. Therefore, the terminal device can determine the position of the first repetition transmission resource in a more flexible manner.

[0033] With reference to the first aspect and the second aspect, in some possible implementation manners, the interval between the nominal adjacent first repetition transmission resources is the interval between any two adjacent first repetition transmission resources in the at least one first repetition transmission resource;

[0034] The determining the position of the at least one first repetition transmission resource in the at least two repetition transmission resources according to the quantity of the at least two repetition transmission resources and the interval between the nominal adjacent first repetition transmission resources includes:

[0035] determining the position of the at least one first repetition transmission resource in the at least two repetition transmission resources according to the quantity of the at least two repetition transmission resources and the interval between any two adjacent first repetition transmission resources in the at least one first repetition transmission resource.

[0036] It can be seen that, in this embodiment, the terminal device can take the interval between the nominal adjacent first repetition transmission resources as the interval between any two adjacent first repetition transmission resources, without considering the problem of uneven repetition transmission resources at the first transmission resource in the time domain edge position, thereby improving the efficiency of determining the position of the first repetition transmission resource.

[0037] With reference to the first aspect and the second aspect, in some possible implementation, the at least one first repetition transmission resource includes the first n1 repetition transmission resources and the last n2 repetition transmission resources.

[0038] The determining the position of the first repetition transmission resource in the at least two repetition transmission resources according to the number of the at least two repetition transmission resources and the interval between the nominal adjacent first repetition transmission resources includes:

[0039] The determining the number of the at least one first repetition transmission resource according to the number of the at least two repetition transmission resources and the interval between the nominal adjacent first repetition transmission resources.

[0040] The determining the position of the first n1 repetition transmission resources in the at least two repetition transmission resources and the position of the last n2 repetition transmission resources in the at least two repetition transmission resources according to the number of the at least two repetition transmission resources and the number of the at least one first repetition transmission resource respectively, wherein the first repetition transmission resource in the at least two repetition transmission resources carries a demodulation reference signal.

[0041] The third interval between any two adjacent first repetition transmission resources in the first n1 repetition transmission resources is different from the fourth interval between any two adjacent first repetition transmission resources in the last n2 repetition transmission resources, and the interval between the last first repetition transmission resource in the first n1 repetition transmission resources and the first first repetition transmission resource in the last n2 repetition transmission resources is the third interval.

[0042] It can be seen that in the embodiment, the terminal device considers that the first transmission resource at the edge of the time domain has the problem of uneven repetition transmission resources, and the first repetition transmission resource is split into two parts in advance; then, the position of each first repetition transmission resource in the two parts is determined respectively, so that the distribution of the first repetition transmission resource is more uniform, and the estimation of the channel is more accurate and reasonable.

[0043] With reference to the first aspect and the second aspect, in some possible implementation, before determining the at least one first repetition transmission resource carrying the reference signal in the at least two repetition transmission resources, the method further includes:

[0044] receiving a first message sent by the network device, the first message being used to determine that the repetition transmission resource i in the at least two repetition transmission resources is cancelled;

[0045] determining the position of the at least one first repeated transmission resource in the at least two repeated transmission resources according to the number of the at least two repeated transmission resources, the interval between the nominal adjacent first repeated transmission resources, and the repeated transmission resource i.

[0046] determining the position of the at least one first repeated transmission resource in the at least two repeated transmission resources according to the number of the at least two repeated transmission resources, the interval between the nominal adjacent first repeated transmission resources, and the repeated transmission resource i.

[0047] It can be seen that in the embodiment, if the terminal device can predict in advance that a certain repeated transmission resource is cancelled, the position of the first repeated transmission resource can be determined in combination with the cancelled repeated transmission resource, so that the distribution of the first repeated transmission resource is more reasonable and is not affected by the cancelled repeated transmission resource.

[0048] In combination with the first aspect and the second aspect, in some possible implementation manners, the determining the position of the at least one first repeated transmission resource in the at least two repeated transmission resources according to the number of the at least two repeated transmission resources, the interval between the nominal adjacent first repeated transmission resources, and the repeated transmission resource i includes:

[0049] determining a first number of the non-cancelled repeated transmission resources after the repeated transmission resource i in the at least two repeated transmission resources;

[0050] determining the position of the first repeated transmission resource in the non-cancelled repeated transmission resources after the repeated transmission resource i according to the first number and the interval between the nominal adjacent first repeated transmission resources, wherein the first repeated transmission resource in the non-cancelled repeated transmission resources after the repeated transmission resource i carries a reference signal.

[0051] It can be seen that in the embodiment, the terminal device will not allocate the first repeated transmission resource to the position of the repeated transmission resource i, and the first repeated transmission resource in the non-cancelled repeated transmission resources after the repeated transmission resource i carries a reference signal, so that after the repeated transmission resource i is interrupted, the non-cancelled repeated transmission resources after the repeated transmission resource i can still have a reference signal to use, without increasing the storage of the receiving end.

[0052] In combination with the first aspect and the second aspect, in some possible implementation manners, the determining the position of the at least one first repeated transmission resource in the at least two repeated transmission resources according to the number of the at least two repeated transmission resources, the interval between the nominal adjacent first repeated transmission resources, and the repeated transmission resource i includes:

[0053] determining a second number of the repeated transmission resources which are not cancelled and located before the repeated transmission resource i among the at least two repeated transmission resources;

[0054] determining a position of a first repeated transmission resource among the repeated transmission resources which are not cancelled and located before the repeated transmission resource i according to the second number and the interval between the nominal adjacent first repeated transmission resources.

[0055] It can be seen that in the embodiment, in the case that the repeated transmission resource i is cancelled, the terminal device regards the repeated transmission resources which are not cancelled and located before the repeated transmission resource i as a plurality of continuous new repeated transmission resources, and determines the position of the first repeated transmission resource, so that the distribution of the repeated transmission resources which are not cancelled and located before the repeated transmission resource i can be relatively uniform in the case that a certain repeated transmission resource is cancelled.

[0056] In combination with the first aspect and the second aspect, in some possible implementation manners, the determining the position of the at least one first repeated transmission resource among the at least two repeated transmission resources according to the number of the at least two repeated transmission resources, the interval between the nominal adjacent first repeated transmission resources and the repeated transmission resource i comprises:

[0057] in the case that it is determined that the transmission phase is discontinuous between the nearest repeated transmission resource which is not cancelled and located before the repeated transmission resource i and the nearest repeated transmission resource which is not cancelled and located after the repeated transmission resource i, or in the case that it is determined that the transmission power difference is not within the first region range configured by the network device between the nearest repeated transmission resource which is not cancelled and located before the repeated transmission resource i and the nearest repeated transmission resource which is not cancelled and located after the repeated transmission resource i, the determining the position of the at least one first repeated transmission resource among the at least two repeated transmission resources according to the number of the at least two repeated transmission resources, the interval between the nominal adjacent first repeated transmission resources and the repeated transmission resource i.

[0058] It can be seen that in the embodiment, the terminal device first determines whether the transmission phase is continuous or the transmission power difference is not within the first region range configured by the network device, if yes, it is determined that the channel used before and after the repeated transmission resource i is different, so that the repeated transmission resource i needs to be considered to determine the position of the first repeated transmission resource; if not, it is determined that the channel used before and after the repeated transmission resource i is same even if the repeated transmission resource i is cancelled, so that the position of the first repeated transmission resource can be determined in a normal manner, and the flexibility of determining the first repeated transmission resource is increased.

[0059] With reference to the first aspect and the second aspect, in some possible implementation, after determining the at least one first repetitive transmission resource carrying the reference signal among the at least two repetitive transmission resources, the method further includes:

[0060] receiving a second message sent by the network device, the second message being used to determine that a repetitive transmission resource j among the at least two repetitive transmission resources is cancelled;

[0061] adjusting a position of the at least one first repetitive transmission resource among the at least two repetitive transmission resources according to the repetitive transmission resource j.

[0062] It can be seen that in the embodiment, if the terminal device cannot predict in advance that the repetitive transmission resource j is cancelled, after determining the position of the first repetitive transmission resource in a normal manner, the position of the first repetitive transmission resource needs to be adjusted again according to the repetitive transmission resource j, so that the position distribution of the first repetitive transmission resource is more reasonable, and the channel estimation is more accurate.

[0063] With reference to the first aspect and the second aspect, in some possible implementation, the adjusting the position of the at least one first repetitive transmission resource among the at least two repetitive transmission resources according to the repetitive transmission resource j includes:

[0064] determining a third quantity of repetitive transmission resources that are not cancelled and are located after the repetitive transmission resource j among the at least two repetitive transmission resources, and a fourth quantity of first repetitive transmission resources that are not cancelled and are located after the repetitive transmission resource j;

[0065] determining the position of the first repetitive transmission resource among the repetitive transmission resources that are not cancelled and are located after the repetitive transmission resource j according to the third quantity and the fourth quantity, wherein the first repetitive transmission resource among the repetitive transmission resources that are not cancelled and are located after the repetitive transmission resource j carries the reference signal.

[0066] It can be seen that in the embodiment, the terminal device can only adjust the position of the first repetitive transmission resource among the repetitive transmission resources that are not cancelled and are located after the repetitive transmission resource j, so that the position of the first repetitive transmission resource can be adjusted faster, and the efficiency of repetitive transmission is improved.

[0067] With reference to the first aspect and the second aspect, in some possible implementation, the determining the third quantity of repetitive transmission resources that are not cancelled and are located after the repetitive transmission resource j among the at least two repetitive transmission resources, and the fourth quantity of first repetitive transmission resources that are not cancelled and are located after the repetitive transmission resource j includes:

[0068] determining a third number of the non-canceled repeated transmission resources after the repeated transmission resource j among the at least two repeated transmission resources and a fourth number of the non-canceled repeated transmission resources after the repeated transmission resource j among the at least two repeated transmission resources, when it is determined that the first time interval is greater than or equal to the first threshold value;

[0069] wherein the first threshold value is determined according to a preparation time length of the terminal device for data transmission, the first time interval is a time interval between a first time and a second time, the first time is a start time of the non-canceled repeated transmission resources after the repeated transmission resource j, and the second time is an end time of receiving the second message.

[0070] It can be seen that, in the embodiment, the terminal device first determines whether the first time interval is greater than or equal to the first threshold value. If yes, it means that it is still possible to adjust the position of the first repeated transmission resource among the non-canceled repeated transmission resources after the repeated transmission resource j, and then the adjustment is performed, so as to ensure the rationality of the adjustment.

[0071] In combination with the first aspect and the second aspect, in some possible implementation manners, the adjusting the position of the at least one first repeated transmission resource among the at least two repeated transmission resources according to the repeated transmission resource j comprises:

[0072] determining a fifth number of the non-canceled repeated transmission resources before the repeated transmission resource j among the at least two repeated transmission resources and a sixth number of the non-canceled first repeated transmission resource before the repeated transmission resource j among the at least two repeated transmission resources;

[0073] determining the position of the first repeated transmission resource among the non-canceled repeated transmission resources before the repeated transmission resource j according to the fifth number and the sixth number, wherein a first repeated transmission resource among the non-canceled repeated transmission resources before the repeated transmission resource j carries a demodulation reference signal.

[0074] It can be seen that, in the embodiment, the terminal device can also adjust the position of the first repeated transmission resource among the non-canceled repeated transmission resources before the repeated transmission resource j, so that the distribution of the first repeated transmission resource among the non-canceled repeated transmission resources before the repeated transmission resource j is reasonable and uniform, and the terminal device can use the reference signal on the first repeated transmission resource to perform accurate channel estimation in the process of performing repeated transmission before the repeated transmission resource j.

[0075] With reference to the first aspect and the second aspect, in some possible implementation, the determining the fifth number of the non-canceled repeated transmission resources before the repeated transmission resource j and the sixth number of the non-canceled first repeated transmission resource before the repeated transmission resource j in the at least two repeated transmission resources comprises:

[0076] In a case where the second time interval is greater than or equal to the first threshold, determining the fifth number of the non-canceled repeated transmission resources before the repeated transmission resource j and the sixth number of the non-canceled first repeated transmission resource before the repeated transmission resource j in the at least two repeated transmission resources.

[0077] The first threshold is determined according to a preparation time length of the terminal device for data transmission, the second time interval is a time interval between a second time and a third time, the second time is an ending time of receiving the second message, and the third time is a starting time of a first repeated transmission resource in the at least two repeated transmission resources.

[0078] It can be seen that, in the embodiment, the terminal device first determines whether the second time interval is greater than or equal to the first threshold. If yes, it indicates that the terminal device has not used the non-canceled repeated transmission resources before the repeated transmission resource j for repeated transmission, and at this time, the position of the first repeated transmission resource in the non-canceled repeated transmission resources before the repeated transmission resource j can be adjusted, so as to ensure the rationality of the adjustment.

[0079] With reference to the first aspect and the second aspect, in some possible implementation, in a case where it is determined that a transmission phase of a nearest non-canceled repeated transmission resource before the repeated transmission resource j and a nearest non-canceled repeated transmission resource after the repeated transmission resource j is discontinuous, or in a case where it is determined that a transmission power difference of the nearest non-canceled repeated transmission resource before the repeated transmission resource j and the nearest non-canceled repeated transmission resource after the repeated transmission resource j is not within a first region range configured by the network device, the position of the at least one first repeated transmission resource in the at least two repeated transmission resources is adjusted according to the repeated transmission resource j.

[0080] It can be seen that in the embodiment, in the case that the repeated transmission resource j is cancelled, the terminal device first determines whether the transmission phase is continuous or whether the transmission power difference is not within the first region range configured by the network device, and if so, determines that the channel used before and after the repeated transmission resource i is cancelled is different, so that the position of the first repeated transmission needs to be adjusted; if not, the repeated transmission can be performed according to the position of the first repeated transmission resource determined previously, without the need for re-adjustment, avoiding additional adjustment and bringing processing pressure to the terminal device.

[0081] In a third aspect, the embodiments of the present application provide a position indication method of a reference signal. The execution subject of the method can be a network device or a chip applied in the network device. Hereinafter, the execution subject is taken as the network device for example.

[0082] receiving a repetition of a reference signal and a downlink channel on at least one first repeated transmission resource, receiving a repetition of the downlink channel on a second repeated transmission resource, or transmitting a repetition of a reference signal and an uplink channel on the at least one first repeated transmission resource, transmitting a repetition of the uplink channel on the second repeated transmission resource, wherein the at least one repeated transmission resource is a repeated transmission resource carrying a reference signal in at least two repeated transmission resources, and the second repeated transmission resource is a repeated transmission resource not carrying a reference signal in the at least two repeated transmission resources.

[0083] It can be seen that in the embodiment, in the process of repeated transmission, transmission can be performed through fewer reference signals, and in this transmission mode, it can be accurately determined which repeated transmission resources carry reference signals and which repeated transmission resources do not carry reference signals, thereby filling the gap in the prior art. In addition, fewer reference signals are used for repeated transmission, compared with the existing repeated transmission mode, a part of time domain resources can be saved, and the saved time domain resources can be used for transmitting data, thereby improving the communication efficiency with the terminal device.

[0084] In a fourth aspect, the embodiments of the present application provide a position indication method of a reference signal, applied to a network device, comprising:

[0085] receive repetitions of a reference signal and a downlink channel on at least one first repetition transmission resource, receive repetitions of the reference signal and the downlink channel on a second repetition transmission resource, or transmit repetitions of a reference signal and an uplink channel on the at least one first repetition transmission resource, transmit repetitions of the reference signal and the uplink channel on the second repetition transmission resource, wherein the at least one repetition transmission resource and the second repetition transmission resource are repetition transmission resources carrying repetitions of a reference signal in the at least two repetition transmission resources, and a number of repetition transmission resources used for carrying repetitions of a reference signal in each of the at least one first repetition transmission resource is greater than a number of repetition transmission resources used for carrying repetitions of a reference signal in the second repetition transmission resource.

[0086] It can be seen that, in the embodiments of the present application, relatively less resources can be used to carry the reference signal on some repetition transmission resources in the process of repetition transmission, and in this transmission mode, it can be accurately determined which repetition transmission resources carry relatively more reference signals and which repetition transmission resources carry relatively less reference signals, which fills the gap in the prior art. In addition, compared with the existing repetition transmission mode, relatively less resources are used to carry the reference signal on some repetition transmission resources for repetition transmission, and a part of resources are saved on these repetition transmission resources for data transmission, thereby improving the communication efficiency with the network device.

[0087] In combination with the third aspect and the fourth aspect, in some possible implementation manners, before receiving repetitions of a reference signal and a downlink channel on at least one first repetition transmission resource, the method further includes:

[0088] sending, to the terminal device, the number of the at least two repetition transmission resources and the number of the at least one first repetition transmission resource, to instruct the terminal device to determine the position of the at least one first repetition transmission resource in the at least two repetition transmission resources according to the number of the at least two repetition transmission resources and the number of the at least one first repetition transmission resource.

[0089] It can be seen that, in the embodiments, the network device can instruct the terminal device to determine the position of the first repetition transmission resource by using the number of the at least two repetition transmission resources and the number of the at least one first repetition transmission resource. Therefore, the manner in which the terminal device determines the position of the first repetition transmission resource is relatively flexible.

[0090] In combination with the third aspect and the fourth aspect, in some possible implementation manners, the terminal device determines the position of the at least one first repetition transmission resource in the at least two repetition transmission resources according to the number of the at least two repetition transmission resources and the number of the at least one first repetition transmission resource, including:

[0091] determine, according to the number of the at least two repeated transmission resources and the number of the at least one first repeated transmission resource, an interval between any two adjacent first repeated transmission resources in the at least one first repeated transmission resource;

[0092] determine, according to the interval between the any two adjacent first repeated transmission resources, a position of the at least one first repeated transmission resource in the at least two repeated transmission resources, wherein a first repeated transmission resource in the at least two repeated transmission resources carries a demodulation reference signal.

[0093] It can be seen that, in the embodiment, the network device indicates that the terminal device can directly determine the interval between any two adjacent first repeated transmission resources according to the number of the two repeated transmission resources and the number of the at least one first repeated transmission resource, without considering the problem of uneven repeated transmission resources at the time domain edge position of the first transmission resource, thereby improving the efficiency of determining the position of the first repeated transmission resource.

[0094] In combination with the third aspect and the fourth aspect, in some possible implementation manners, the at least one first repeated transmission resource includes m1 first repeated transmission resources in front and m2 first repeated transmission resources at back; and the determining, according to the number of the at least two repeated transmission resources and the number of the at least one first repeated transmission resource, the position of the at least one first repeated transmission resource in the at least two repeated transmission resources, includes:

[0095] determining, according to the number of the at least two repeated transmission resources and the number of the at least one first repeated transmission resource, respectively, the position of the m1 first repeated transmission resources in front in the at least two repeated transmission resources and the position of the m2 first repeated transmission resources at back in the at least two repeated transmission resources, wherein a first repeated transmission resource in the at least two repeated transmission resources carries a demodulation reference signal;

[0096] wherein a first interval between any two adjacent first repeated transmission resources in the m1 first repeated transmission resources in front is different from a second interval between any two adjacent first repeated transmission resources in the m2 first repeated transmission resources at back, and an interval between a last first repeated transmission resource in the m1 first repeated transmission resources in front and a first first repeated transmission resource in the m2 first repeated transmission resources at back is the first interval.

[0097] It can be seen that in the embodiment, the network device instructs the terminal device to consider that the first transmission resource at the edge position in the time domain may exist the problem of uneven distribution of repeated transmission resources, and the first repeated transmission resource can be split into two parts in advance, so that the distribution of the first repeated transmission resource is more uniform, and the estimation of the channel is more accurate and reasonable.

[0098] In combination with the third aspect and the fourth aspect, in some possible implementation manners, before receiving the repetitions of the reference signal and the downlink channel on the at least one first repeated transmission resource, the method further includes:

[0099] sending, to the terminal device, the number of the at least two repeated transmission resources and the interval between the nominal adjacent first repeated transmission resources, to instruct the terminal device to determine the position of the at least one first repeated transmission resource in the at least two repeated transmission resources according to the number of the at least two repeated transmission resources and the interval between the nominal adjacent first repeated transmission resources.

[0100] It can be seen that in the embodiment, the network device instructs the terminal device to determine the position of the first repeated transmission resource through the number of the at least two repeated transmission resources and the interval between the nominal adjacent first repeated transmission resources. Therefore, the terminal device can flexibly determine the position of the first repeated transmission resource.

[0101] In combination with the third aspect and the fourth aspect, in some possible implementation manners, the interval between the nominal adjacent first repeated transmission resources is the interval between any two adjacent first repeated transmission resources in the at least one first repeated transmission resource; and the determining of the position of the at least one first repeated transmission resource in the at least two repeated transmission resources according to the number of the at least two repeated transmission resources and the interval between the nominal adjacent first repeated transmission resources includes:

[0102] determining the position of the at least one first repeated transmission resource in the at least two repeated transmission resources according to the number of the at least two repeated transmission resources and the interval between any two adjacent first repeated transmission resources in the at least one first repeated transmission resource.

[0103] It can be seen that in the embodiment, the network device instructs the terminal device to take the interval between the nominal adjacent first repeated transmission resources as the interval between any two adjacent first repeated transmission resources, without considering that the first transmission resource at the edge position in the time domain may exist the problem of uneven distribution of repeated transmission resources, thereby improving the efficiency of determining the position of the first repeated transmission resource.

[0104] In combination with the third aspect and the fourth aspect, in some possible implementation manners, the at least one first repeated transmission resource includes n1 front first repeated transmission resources and n2 rear first repeated transmission resources; and the determining, according to the number of the at least two repeated transmission resources and the interval between the nominal adjacent first repeated transmission resources, the position of the at least one first repeated transmission resource in the at least two repeated transmission resources includes:

[0105] determining the number of the at least one first repeated transmission resource according to the number of the at least two repeated transmission resources and the interval between the nominal adjacent first repeated transmission resources;

[0106] determining the position of the n1 front first repeated transmission resources in the at least two repeated transmission resources and the position of the n2 rear first repeated transmission resources in the at least two repeated transmission resources respectively according to the number of the at least two repeated transmission resources and the number of the at least one first repeated transmission resource, wherein a first repeated transmission resource in the at least two repeated transmission resources carries a demodulation reference signal;

[0107] wherein a third interval between any two adjacent first repeated transmission resources in the n1 front first repeated transmission resources is different from a fourth interval between any two adjacent first repeated transmission resources in the n2 rear first repeated transmission resources, and an interval between a last first repeated transmission resource in the n1 front first repeated transmission resources and a first first repeated transmission resource in the n2 rear first repeated transmission resources is the third interval.

[0108] It can be seen that, in the embodiment, the network device instructs the terminal device to consider that the first transmission resource at the time domain edge position may exist the problem of uneven repeated transmission resources, therefore, the terminal device can split the first repeated transmission resource into two parts in advance; then, the position of each first repeated transmission resource in the two parts is determined respectively, so that the distribution of the first repeated transmission resource is more uniform, and the estimation of the channel is more accurate and reasonable.

[0109] In combination with the third aspect and the fourth aspect, in some possible implementation manners, before the number of the at least two repeated transmission resources and the number of the at least one first repeated transmission resource are sent to the terminal device, the method further includes:

[0110] sending a first message to the terminal device, the first message being used to indicate that a repetition transmission resource i of the at least two repetition transmission resources is cancelled; and instruct the terminal device to determine a position of the at least one first repetition transmission resource in the at least two repetition transmission resources according to a number of the at least two repetition transmission resources, an interval between the nominally adjacent first repetition transmission resources, and the repetition transmission resource i.

[0111] It can be seen that in the embodiment, the network device early informs the terminal device that a repetition transmission resource is cancelled, and instructs the terminal device to determine the position of the first repetition transmission resource in combination with the cancelled repetition transmission resource, so that the distribution of the first repetition transmission resource is more reasonable and is not affected by the cancelled transmission resource.

[0112] In combination with the third aspect and the fourth aspect, in some possible implementation manners, the determining the position of the at least one first repetition transmission resource in the at least two repetition transmission resources according to the number of the at least two repetition transmission resources, the interval between the nominally adjacent first repetition transmission resources, and the repetition transmission resource i includes:

[0113] determining a first number of the non-cancelled repetition transmission resources after the repetition transmission resource i in the at least two repetition transmission resources;

[0114] determining a position of a first repetition transmission resource after the repetition transmission resource i in the non-cancelled repetition transmission resources according to the first number and the interval between the nominally adjacent first repetition transmission resources, wherein the first repetition transmission resource after the repetition transmission resource i in the non-cancelled repetition transmission resources carries a reference signal.

[0115] It can be seen that in the embodiment, the network device instructs the terminal device not to allocate the first repetition transmission resource to the position of the repetition transmission resource i, and the first repetition transmission resource after the repetition transmission resource i in the non-cancelled repetition transmission resources carries a reference signal, so that after the repetition transmission resource i is interrupted, the non-cancelled repetition transmission resources after the repetition transmission resource i can still have a reference signal to use, without increasing the storage of the receiving end.

[0116] In combination with the third aspect and the fourth aspect, in some possible implementation manners, the determining the position of the at least one first repetition transmission resource in the at least two repetition transmission resources according to the number of the at least two repetition transmission resources, the interval between the nominally adjacent first repetition transmission resources, and the repetition transmission resource i includes:

[0117] determining a second number of the repeated transmission resources, which are located before the repeated transmission resource i and are not cancelled, from the at least two repeated transmission resources;

[0118] determining a position of a first repeated transmission resource from the repeated transmission resources, which are located before the repeated transmission resource i and are not cancelled, according to the second number and an interval between the nominal adjacent first repeated transmission resources.

[0119] It can be seen that, in the embodiment, in the case that the repeated transmission resource i is cancelled, the network device instructs the terminal device to regard the repeated transmission resources, which are located before the repeated transmission resource i and are not cancelled, as a plurality of continuous new repeated transmission resources, and determines the first repeated transmission resource, so that the distribution of the repeated transmission resources, which are located before the repeated transmission resource i and are not cancelled, can be relatively uniform in the case that a certain repeated transmission resource is cancelled.

[0120] In combination with the third aspect and the fourth aspect, in some possible implementation manners, the determining the position of the at least one first repeated transmission resource from the at least two repeated transmission resources according to the number of the at least two repeated transmission resources, the interval between the nominal adjacent first repeated transmission resources and the repeated transmission resource i comprises:

[0121] in the case that it is determined that a transmission phase is discontinuous between a nearest repeated transmission resource before the repeated transmission resource i and a nearest repeated transmission resource after the repeated transmission resource i, or in the case that it is determined that a transmission power difference is not within a first region configured by the network device between the nearest repeated transmission resource before the repeated transmission resource i and the nearest repeated transmission resource after the repeated transmission resource i, the determining the position of the at least one first repeated transmission resource from the at least two repeated transmission resources according to the number of the at least two repeated transmission resources, the interval between the nominal adjacent first repeated transmission resources and the repeated transmission resource i.

[0122] It can be seen that, in the embodiment, the network device instructs the terminal device to first determine whether a transmission phase is continuous or a transmission power difference is not within a first region configured by the network device, if yes, it is determined that a channel used before and after the repeated transmission resource i is different, so that the repeated transmission resource i needs to be considered to determine the position of the first repeated transmission resource; if not, it is determined that a channel used before and after the repeated transmission resource i is same even if the repeated transmission resource i is cancelled, so that the position of the first repeated transmission resource can be determined in a normal manner, and the flexibility of determining the first repeated transmission resource is increased.

[0123] With reference to the third aspect and the fourth aspect, in some possible implementation, after the number of the at least two repeated transmission resources and the number of the at least one first repeated transmission resource are sent to the terminal device, the method further includes:

[0124] sending, to the network device, a second message, the second message being used to indicate that a repeated transmission resource j in the at least two repeated transmission resources is cancelled, and instruct the terminal device to adjust a position of the at least one first repeated transmission resource in the at least two repeated transmission resources according to the repeated transmission resource j.

[0125] It can be seen that, in this embodiment, after the terminal device determines the first repeated transmission position, it is found that a high-priority transmission needs to be transmitted, the network device cancels the repeated transmission resource j, and instructs the terminal device to re-adjust the position of the first repeated transmission resource according to the repeated transmission resource j after the position of the first repeated transmission resource is determined in a normal manner, so that the position distribution of the first repeated transmission resource is more reasonable, and the channel estimation is more accurate.

[0126] With reference to the third aspect and the fourth aspect, in some possible implementation, the adjusting the position of the at least one first repeated transmission resource in the at least two repeated transmission resources according to the repeated transmission resource j includes:

[0127] determining a third number of repeated transmission resources that are not cancelled and are located after the repeated transmission resource j in the at least two repeated transmission resources, and a fourth number of first repeated transmission resources that are not cancelled and are located after the repeated transmission resource j;

[0128] determining a position of a first repeated transmission resource in the repeated transmission resources that are not cancelled and are located after the repeated transmission resource j according to the third number and the fourth number, wherein a first repeated transmission resource in the repeated transmission resources that are not cancelled and are located after the repeated transmission resource j carries a reference signal.

[0129] It can be seen that, in this embodiment, the network device instructs the terminal device to adjust only the position of the first repeated transmission resource in the repeated transmission resources that are not cancelled and are located after the repeated transmission resource j, so that the position of the first repeated transmission resource can be adjusted faster, and the efficiency of repeated transmission is improved.

[0130] With reference to the third aspect and the fourth aspect, in some possible implementation, the determining the third number of repeated transmission resources that are not cancelled and are located after the repeated transmission resource j in the at least two repeated transmission resources, and the fourth number of first repeated transmission resources that are not cancelled and are located after the repeated transmission resource j includes:

[0131] determining a third number of the non-canceled repeated transmission resources after the repeated transmission resource j among the at least two repeated transmission resources, and a fourth number of the non-canceled repeated transmission resources after the repeated transmission resource j, in a case that the first time interval is greater than or equal to the first threshold value;

[0132] wherein the first threshold value is determined according to a preparation time length of the terminal device for data transmission, the first time interval is a time interval between a first time and a second time, the first time is a start time of the non-canceled repeated transmission resources after the repeated transmission resource j, and the second time is an end time of receiving the second message.

[0133] It can be seen that in the embodiment, the network device instructs the terminal device to first determine whether the first time interval is greater than or equal to the first threshold value, and if so, that is, there is still time to adjust the position of the first repeated transmission resource among the non-canceled repeated transmission resources after the repeated transmission resource j, and then adjust to ensure the rationality of the adjustment.

[0134] In combination with the third aspect and the fourth aspect, in some possible implementation manners, the adjusting the position of the at least one first repeated transmission resource among the at least two repeated transmission resources according to the repeated transmission resource j comprises:

[0135] determining a fifth number of the non-canceled repeated transmission resources before the repeated transmission resource j among the at least two repeated transmission resources, and a sixth number of the non-canceled first repeated transmission resource before the repeated transmission resource j;

[0136] determining the position of the first repeated transmission resource among the non-canceled repeated transmission resources before the repeated transmission resource j according to the fifth number and the sixth number, wherein a first repeated transmission resource among the non-canceled repeated transmission resources before the repeated transmission resource j carries a demodulation reference signal.

[0137] It can be seen that in the embodiment, the network device instructs the terminal device to further adjust the position of the first repeated transmission resource among the non-canceled repeated transmission resources before the repeated transmission resource j, which can make the distribution of the first repeated transmission resource among the non-canceled repeated transmission resources before the repeated transmission resource j more reasonable and uniform, so that the terminal device can use the reference signal on the first repeated transmission resource for accurate channel estimation in the process of performing repeated transmission before the repeated transmission resource j.

[0138] With reference to the third aspect and the fourth aspect, in some possible implementation, the determining the fifth number of the non-canceled repeated transmission resources before the repeated transmission resource j among the at least two repeated transmission resources, and the sixth number of the non-canceled repeated transmission resources before the repeated transmission resource j among the at least two repeated transmission resources comprises:

[0139] In a case where the second time interval is greater than or equal to the first threshold, determining the fifth number of the non-canceled repeated transmission resources before the repeated transmission resource j among the at least two repeated transmission resources, and the sixth number of the non-canceled first repeated transmission resource before the repeated transmission resource j among the at least two repeated transmission resources.

[0140] The first threshold is determined according to a preparation duration of the terminal device for data transmission, the second time interval is a time interval between a second time and a third time, the second time is an ending time of receiving the second message, and the third time is a starting time of a first repeated transmission resource among the at least two repeated transmission resources.

[0141] It can be seen that, in the embodiment, the network device instructs the terminal device to first determine whether the second time interval is greater than or equal to the first threshold. If yes, it indicates that the terminal device has not used the non-canceled repeated transmission resources before the repeated transmission resource j for repeated transmission, and at this time, the position of the first repeated transmission resource among the non-canceled repeated transmission resources before the repeated transmission resource j can be adjusted, thereby ensuring the rationality of the adjustment.

[0142] With reference to the third aspect and the fourth aspect, in some possible implementation, the adjusting the position of the at least one first repeated transmission resource among the at least two repeated transmission resources according to the repeated transmission resource j comprises:

[0143] In a case where it is determined that a transmission phase of a nearest non-canceled repeated transmission resource before the repeated transmission resource j and a nearest non-canceled repeated transmission resource after the repeated transmission resource j is discontinuous, or in a case where it is determined that a transmission power difference between the nearest non-canceled repeated transmission resource before the repeated transmission resource j and the nearest non-canceled repeated transmission resource after the repeated transmission resource j is not within a first region range configured by the network device, the position of the at least one first repeated transmission resource among the at least two repeated transmission resources is adjusted according to the repeated transmission resource j.

[0144] It can be seen that in the embodiment, in the case that the repeated transmission resource j is cancelled, the network device instructs the terminal device to first determine whether the sending phase is continuous or whether the sending power difference is not within the first region range configured by the network device, if yes, it is determined that the channel used before and after the repeated transmission resource i is cancelled is different, so that the position of the first repeated transmission needs to be re-adjusted; if not, the repeated transmission can be performed according to the position of the first repeated transmission resource previously determined, without the need for re-adjustment, avoiding additional adjustment and bringing processing pressure to the terminal device.

[0270] The technical solutions in the embodiments of the present application can be applied to various communication systems. For example, the fifth generation (5th generation, 5G) mobile communication system and future mobile communication systems.

[0271] The terminal device related to the embodiments of the present application may, for example, be a user equipment (UE). The UE may be a device that provides voice and / or data connectivity to a user, and may include, for example, a handheld device having wireless connection capability, or a processing device connected to a wireless modem. The UE may communicate with a core network via a radio access network (RAN), and exchange voice and / or data with the RAN. The UE may include a wireless user equipment, a mobile user equipment, a device-to-device (D2D) user equipment, a vehicle-to-everything (V2X) user equipment, a machine-to-machine / Machine-Type Communications (M2M / MTC) user equipment, an Internet of Things (IoT) user equipment, a subscriber unit, a subscriber station, a mobile station, a remote station, an access point (AP), a remote terminal, an access terminal, a user terminal, a user agent, or a user device, etc. For example, it may include a mobile telephone (also known as a "cellular" telephone), a computer with mobile user equipment, a portable, pocket, handheld, built-in, or car-mounted device, etc. For example, it may include a personal communication service (PCS) phone, a cordless phone, a session initiation protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), etc. It may also include a restricted device, such as a low-energy device, or a device with limited storage capacity, or a device with limited computing capability, etc. For example, it may include a bar code, a radio frequency identification (RFID), a sensor, a global positioning system (GPS), a laser scanner, etc.

[0272] By way of example and not limitation, in embodiments of the present application, the UE can also be a wearable device. The wearable device can also be referred to as a smart wearable device, a smart wearable device, or the like, and is a general term for devices that are designed and developed by applying wearable technology to daily wear, such as glasses, gloves, watches, clothing, and shoes. The wearable device is a portable device that is directly worn on the body or integrated into the clothes or accessories of the user. The wearable device is not only a hardware device, but also has powerful functions through software support and data interaction, cloud interaction. The general wearable smart device includes a full function, a large size, and can realize complete or partial functions without relying on a smart phone, such as a smart watch or smart glasses, and focuses on a certain application function and needs to cooperate with other devices such as a smart phone, such as various smart wristbands, smart helmets, smart jewelry, and the like for monitoring vital signs.

[0273] Various UEs as introduced above, if located on a vehicle (for example, placed in or installed in a vehicle), can be considered as an on-board user equipment, which is also referred to as an on-board unit (OBU), and embodiments of the present application do not limit this.

[0274] Embodiments of the present application also relate to a network device, which can be an access network (AN) device for example. The AN device can refer to a device in an access network that communicates with wireless user equipment (UE) over the air through one or more cells, such as a base station (NodeB, e.g., an access point), which can be configured to convert received over-the-air frames to Internet Protocol (IP) packets and vice versa as a router between the UE and the rest of the access network, which can include an IP network. For example, the NodeB can be an evolved NodeB (eNB or e-NodeB) in a long term evolution (LTE) system or long term evolution-advanced (LTE-A) system, or can also include a new radio network device gNB in a 5th generation (5G) NR system. The AN device can also be a road side unit (RSU) in a vehicle to everything (V2X) technology. The RSU can be a fixed infrastructure entity that supports V2X applications and can exchange messages with other entities that support V2X applications. In addition, the AN device can also include a centralized unit (CU) and a distributed unit (DU) in a cloud radio access network (CloudRAN) system, in which case the AN device coordinates the management of properties of the air interface. Embodiments of the present application do not limit the AN device.

[0275] In order to facilitate understanding of the present application, first, relevant technical knowledge related to embodiments of the present application is introduced.

[0276] In the NR system, multiple repetition transmissions can be performed in the uplink and downlink transmission process between the terminal device and the network device, that is, the same information is transmitted on the multiple repetitions. The sending end needs to send one or more RSs on the time domain resource corresponding to each repetition in order for the terminal device or network device to perform estimation, such as a demodulation reference signal (DM-RS), which is used by the terminal device or network device for channel estimation to demodulate the information sent by the sending end on the repetition.

[0277] As Figure 1As shown in FIG. 6, each box represents a repetition, and the gray box in the box represents the position of the time domain resource to be used when the sending end sends the DM-RS corresponding to each repetition. As can be seen, the sending end sends one DM-RS corresponding to each repetition on the corresponding time domain resource, and the receiving end can use the DM-RS to perform channel estimation and demodulate the data transmitted by the sending end on the repetition.

[0278] As shown in FIG. 6, each box represents a repetition, and the gray box in the box represents the position of the time domain resource to be used when the sending end sends the DM-RS corresponding to each repetition. As can be seen, the sending end sends one DM-RS corresponding to each repetition on the corresponding time domain resource, and the receiving end can use the DM-RS to perform channel estimation and demodulate the data transmitted by the sending end on the repetition. Figure 2

[0279] At present, in the discussion of the coverage enhancement feature, it is proposed that in the case of channel slow variation, fewer reference signals can be used for repeated transmission, such as DM-RS less technology. That is, the sending end can not send DM-RS on the time domain resource corresponding to some repetitions, because of the channel slow variation, the channel estimation corresponding to the repetition can be realized through the DM-RS sent on the time domain resource of the previous repetition.

[0280] However, the DM-RS less technology changes the correspondence between the DM-RS and the repetition, how the network device indicates the position of the DM-RS and how the terminal device determines the position of the DM-RS in multiple repetitions are still in the blank stage.

[0281] Refer to Figure 3 , Figure 3 A structural schematic diagram of a communication system provided by an embodiment of the present application. The communication system 10 includes a terminal device 100 and a network device 200.

[0282] In an embodiment of the present application, in Figure 3 ​In the illustrated communication system, the terminal device 100 determines at least one first repeated transmission resource in at least two repeated transmission resources that carries a reference signal, wherein there is a second repeated transmission resource in the at least two repeated transmission resources that does not carry a reference signal; in the process of downlink transmission, the terminal device 100 receives the repeated transmission of the received reference signal and the downlink channel sent by the network device 200 on the at least one repeated transmission resource, and receives the repeated transmission of the downlink channel on the second repeated transmission resource; or in the process of uplink transmission, the terminal device 100 sends the reference signal to the network device 200 on the at least one repeated transmission resource, and sends the repeated transmission of the uplink channel on the second repeated transmission resource. The reference signal can be a demodulation reference signal.

[0283] It can be seen that in the present embodiment, the terminal device 100 and the network device 200 can perform transmission by using fewer reference signals in the process of repeated transmission, and in this transmission mode, the terminal device can accurately determine which repeated transmission resources in the repeated transmission resources carry a demodulation reference signal and which repeated transmission resources do not carry a demodulation reference signal, thereby making up for the blank in the prior art. In addition, compared with the existing repeated transmission mode, the use of fewer reference signals for repeated transmission can save a part of time domain resources, and the saved time domain resources can be used for transmitting data, thereby improving the communication efficiency between the terminal device 100 and the network device 200.

[0284] In another embodiment of the present application, in Figure 3 In the illustrated communication system, the terminal device 100 determines at least one first repeated transmission resource in at least two repeated transmission resources that carries a reference signal, wherein there is a second repeated transmission resource in the at least two repeated transmission resources that also carries a reference signal, but the number of repeated transmission resources for carrying a reference signal in each of the at least one first repeated transmission resource is more than the number of repeated transmission resources for carrying a reference signal in the second repeated transmission resource, that is, the number of reference signals carried in the first repeated transmission resource is relatively large, and the number of reference signals carried in the second repeated transmission resource is relatively small; since the first repeated transmission resource and the second repeated transmission resource both carry a reference signal, in the process of downlink transmission, the terminal device 100 receives the repeated transmission of the received reference signal and the downlink channel sent by the network device 200 on the at least one repeated transmission resource, and receives the repeated transmission of the received reference signal and the downlink channel sent by the network device 200 on the second repeated transmission resource; or in the process of uplink transmission, the terminal device 100 sends the reference signal to the network device 200 on the at least one repeated transmission resource, and sends the reference signal and the repeated transmission of the uplink channel on the second repeated transmission resource.

[0285] It can be seen that, in the embodiment of the present application, in the process of repeated transmission, relatively less resources are used to carry reference signals on some repeated transmission resources, relatively more resources are used to carry reference signals on some repeated transmission resources, and in this transmission mode, it can be accurately determined which repeated transmission resources carry relatively more reference signals and which repeated transmission resources carry relatively less reference signals, which makes up for the blank in the prior art. In addition, compared with the existing repeated transmission mode, relatively less resources are used to carry reference signals on some repeated transmission resources for repeated transmission, and a part of resources are saved on these repeated transmission resources for transmitting data, thereby improving the communication efficiency with the network device.

[0286] Reference is made to Figure 4 , Figure 4 A flowchart of a reference signal position determination method provided by the embodiment of the present application is shown. The method of the embodiment includes the following steps:

[0287] 401: The terminal device determines at least one first repeated transmission resource carrying reference signals in at least two repeated transmission resources, wherein there is a second repeated transmission resource not carrying reference signals in the at least two repeated transmission resources.

[0288] The repeated transmission resource is the time domain resource corresponding to each repeated transmission, and one repeated transmission is performed on each repeated transmission resource, that is, the repeated transmission resource and the repeated transmission are one-to-one corresponding, and the information transmitted by multiple repeated transmissions is the same. Since there is a second repeated transmission resource not carrying reference signals in the at least two repeated transmission resources, that is, reference signals are not transmitted on some repeated transmission resources.

[0289] The reference signal can be a demodulation reference signal or other reference signal. The present application does not limit the form of the reference signal.

[0290] 402: The terminal device receives repeated transmission of reference signals and downlink channels on the at least first repeated transmission resource, receives repeated transmission of the downlink channels on the second repeated transmission resource, or transmits repeated transmission of reference signals and uplink channels on the at least first repeated transmission resource, and transmits repeated transmission of the uplink channels on the second repeated transmission resource.

[0291] Since the first repetition transmission resource carries the reference signal, in the process of downlink transmission, the terminal device receives the reference signal on the first repetition transmission resource in addition to receiving the repetition of the downlink channel, and only receives the repetition of the downlink channel on the second repetition transmission resource. Since repetition transmission is performed, the data transmitted on each repetition is the same, so the repetition of the downlink channel received by the terminal device on the first repetition transmission resource is the same as the repetition of the downlink channel received on the second repetition transmission resource. For example, both can be repetitions of a physical downlink shared channel (PDSCH) or repetitions of a physical downlink control channel (PDCCH).

[0292] Similarly, since the first repetition transmission resource carries the reference signal, in the process of uplink transmission, the terminal device transmits the reference signal on the first repetition transmission resource in addition to transmitting the repetition of the uplink channel, and only transmits the repetition of the uplink channel on the second repetition transmission resource. Since repetition transmission is performed, the data transmitted on each repetition is the same, so the repetition of the uplink channel transmitted by the terminal device on the first repetition transmission resource is the same as the repetition of the uplink channel transmitted on the second repetition transmission resource. For example, both can be repetitions of a physical uplink shared channel (PUSCH) or repetitions of a physical uplink control channel (PUCCH).

[0293] It can be seen that, in the embodiments of the present application, the terminal device and the network device can perform repetition transmission through fewer reference signals in the process of repetition transmission, and in this transmission mode, the terminal device can accurately determine which repetition transmission resources in the repetition transmission resources carry the reference signal and which repetition transmission resources do not carry the demodulation reference signal, which fills the gap in the prior art. In addition, using fewer reference signals for repetition transmission can save a part of time domain resources compared with the existing repetition transmission mode, and the saved time domain resources can be used to transmit data, thereby improving the communication efficiency between the terminal device and the network device.

[0294] In some possible implementation manners, in the process of downlink transmission, the terminal device receives the reference signal on the at least one first repetition transmission resource and receives the repetition of the downlink channel on the second repetition transmission resource, or, in the process of uplink transmission, the terminal device transmits the reference signal on the at least one first repetition transmission resource and transmits the repetition of the uplink channel on the second repetition transmission resource.

[0295] It should be noted that the reason for transmitting or receiving the reference signal only on the first repeated transmission resource is that part of the resources in the first repeated transmission resource is affected, so that there is no extra resource to carry the repetition of the uplink channel or the downlink channel. For example, in the case where the first repeated transmission resource is occupied and only one symbol can be used, the reference signal is carried on the one symbol at this time. However, in the prior art, when part of the repeated transmission resource of a repeated transmission is affected, the transmission or reception of the reference signal on the repeated transmission is abandoned.

[0296] As can be seen, in the embodiment, even if part of the repeated transmission resource of a repeated transmission is affected, the terminal device can still transmit or receive the reference signal on the repeated transmission resource, thereby providing the reference signal for other repeated transmissions located after the repeated transmission corresponding to the repeated transmission resource. The terminal device can use the reference signal to perform channel estimation for other repeated transmissions, thereby improving the transmission success rate of the other repeated transmissions.

[0297] In some possible embodiments, multiple repeated transmissions can be performed on one slot, and the terminal device can transmit and receive the reference signal only on the first repeated transmission in the slot and not on other repeated transmissions in the slot. The terminal device transmits and receives the reference signal in a slot, so that the channel estimation of the network device and the terminal device is more regular and simple to implement. The slot is a slot in the NR system. It can be understood that in a future higher-order communication system, the slot herein can be a time unit, and the time unit includes a plurality of Orthogonal Frequency Division Multiplexing (OFDM) symbols specified in the protocol.

[0298] Referring to Figure 5 , Figure 5 Another flowchart of a method for determining the position of a reference signal is provided in the embodiment. The embodiment is the same as the embodiment shown in Figure 4 , and will not be described here. The method of the embodiment includes the following steps:

[0299] 501: The network device transmits to the terminal device the number of at least two repeated transmission resources and the number of at least one first repeated transmission resource.

[0300] Exemplarily, the network device can send the number of the at least two repeated transmission resources and the number of the at least one first repeated transmission resource to the terminal device through a signaling, which can be one of a physical layer signaling or a high layer signaling, and the present application does not limit the signaling.

[0301] Exemplarily, the network device can also send the number of the at least two repeated transmission resources and the number of the at least one first repeated transmission resource to the terminal device through different signaling, for example, sending the number of the at least two repeated transmission resources to the terminal device through a first signaling and sending the number of the at least one first repeated transmission resource to the terminal device through a second signaling. The first signaling and the second signaling can be the same type of signaling or different types of signaling. For example, the first signaling and the second signaling can both be a high layer signaling or a physical layer signaling; for another example, the first signaling is a high layer signaling and the second signaling is a physical layer signaling, or the first signaling is a physical layer signaling and the second signaling is a high layer signaling. And, as a high layer signaling or a physical layer signaling, the first signaling and the second signaling can be the same signaling or different signaling. Therefore, the present application does not limit the form of the first signaling and the second signaling.

[0302] 502: The terminal device determines the position of the at least one first repeated transmission resource in the at least two repeated transmission resources according to the number of the at least two repeated transmission resources and the number of the at least one first repeated transmission resource.

[0303] The determination of the position of the first repeated transmission resource in the at least two repeated transmission resources is to determine which repeated transmission resource in the at least two repeated transmission resources carries the demodulation reference signal.

[0304] Exemplarily, the terminal device determines the interval between any two adjacent first repeated transmission resources in the at least one first repeated transmission resource according to the number of the at least two repeated transmission resources and the number of the at least one first repeated transmission resource, and determines the position of the at least one repeated transmission resource in the at least two repeated transmission resources according to the interval between the any two adjacent first repeated transmission resources. The first repeated transmission resource in the at least two repeated transmission resources carries the demodulation reference signal.

[0305] As shown in Figure 6 From the first repeated transmission resource in the two repeated transmission resources, the position of all first repeated transmission resources is sequentially determined from the at least two repeated transmission resources according to the determined interval.

[0306] The interval can be the number of the second repeated transmission resources between any two adjacent first repeated transmission resources, as shown in Figure 6As shown, the interval is two second repetition transmission resources. In addition, the interval can also be the number of repetition transmission resources between the two adjacent first repetition transmission resources, which includes the number of second repetition transmission resources between the two adjacent first repetition transmission resources and one of the two adjacent first repetition transmission resources, such as Figure 6 As shown, the interval is three repetition transmission resources, i.e. two second repetition transmission resources and one first repetition transmission resource. The intervals mentioned later are similar to this, and are not described again.

[0307] For example, in the case that the interval is the number of second repetition transmission resources between any two adjacent first repetition transmission resources, the interval can be expressed by formula (1):

[0308]

[0309] wherein I is the interval, N is the number of at least two second repetition transmission resources, and K is the number of at least one first repetition transmission, is the upward rounding.

[0310] In the case that the interval is the number of repetition transmission resources between the two adjacent first repetition transmission resources, the interval can be expressed by formula (2):

[0311]

[0312] wherein I is the interval, N is the number of at least two second repetition transmission resources, and K is the number of at least one first repetition transmission, is the upward rounding.

[0313] In some possible embodiments, in the case that the ratio of the number of at least two repetition transmission resources to the number of at least one first repetition transmission resource is not an integer, the number of repetition transmissions corresponding to the first repetition transmission resource at the time domain edge position (such as the first repetition transmission resource or the last repetition transmission resource) in the at least one first repetition transmission resource is different from the number of repetition transmissions corresponding to other first repetition transmission resources in the at least one repetition transmission resource.

[0314] For example, as shown in FIG. 6, the interval is the number of second repetition transmission resources between the two adjacent first repetition transmission resources, and the interval is expressed by formula (1). Figure 6As shown, each of the first three first repetition transmission resources corresponds to three repeated transmissions, for example, the reference signal transmitted on the first repetition transmission resource can be used as channel estimation for the first three repeated transmissions, while the demodulation reference signal transmitted on the last repetition transmission resource is only used for channel estimation of the last repeated transmission. Therefore, this way of allocating first repetition transmission resources results in a non-uniform distribution of first repetition transmission resources. A reasonable allocation method should be redesigned.

[0315] For example, the at least one repetition transmission resource can be split into two parts, i.e., the at least one repetition includes the first m1 first repetition transmission resources and the last m2 first repetition transmission resources. The terminal device can determine the positions of the first m1 first repetition transmission resources in the at least two repetition transmission resources and the positions of the last m2 first repetition transmission resources in the at least two repetition transmission resources according to the number of the at least two repetition transmission resources and the number of the at least one repetition transmission resource. The first repetition transmission resource in the at least two repetition transmission resources carries a demodulation reference signal, i.e., the first first repetition transmission resource in the first m1 first repetition transmission resources is the first repetition transmission resource in the at least two first repetition transmission resources.

[0316] The first interval between any two adjacent first repetition transmission resources in the first m1 first repetition transmission resources is different from the second interval between any two adjacent first repetition transmission resources in the last m2 first repetition transmission resources, and the interval between the last first repetition transmission resource in the first m1 first repetition transmission resources and the first first repetition transmission resource in the last m2 first repetition transmission resources is the first interval.

[0317] For example, the terminal device determines m1, m2, the first interval and the second interval according to the number of the at least two repetition transmission resources and the number of the at least one first repetition transmission resource. According to the first interval, the positions of the first m1 first repetition transmission resources in the at least two repetition transmission resources are determined. That is, the terminal device starts from the first repetition transmission resource in the at least two repetition transmission resources and determines the positions of the first m1 first repetition transmission resources in the at least two second repetition transmission resources according to the first interval.

[0318] For example, in the case of the number of repetition transmission resources with an interval between any two adjacent first repetition transmission resources, the first interval is In the case of the number of second repetition transmission resources with an interval between any two adjacent first repetition transmission resources, the first interval is And m1 can be represented by formula (3):

[0319]

[0320] wherein N is the number of the at least two second repetition transmission resources, and K is the number of the at least one first repetition transmission is rounded up.

[0321] According to the first interval, the positions of the first m1 first repetition transmission resources in the at least two repetition transmission resources are determined. That is, the terminal device starts from the first repetition transmission resource in the at least two repetition transmission resources, and determines the positions of the first m1 first repetition transmission resources in the at least two second repetition transmission resources according to the first interval in sequence.

[0322] For example, in the case that the interval is the number of repetition transmission resources between any two adjacent first repetition transmission resources, then the second interval is In the case that the interval is the number of second repetition transmission resources between any two adjacent first repetition transmission resources, then the first interval is and m2 can be represented by formula (4):

[0323]

[0324] wherein N is the number of the at least two second repetition transmission resources, and K is the number of the at least one first repetition transmission is rounded up.

[0325] The terminal device first determines the position of the first repetition transmission resource in the last m2 first repetition transmission resources according to the position of the last first repetition transmission resource in the first m1 first repetition transmission resources and the first interval; and then, starting from the first repetition transmission resource in the last m2 first repetition transmission resources, determines the positions of the last m2 first repetition transmission resources in the at least two second repetition transmission resources according to the second interval in sequence.

[0326] For example, as Figure 7As shown, if the number of repeated transmission resources is 10, and the number of first repeated transmission resources is 4, it can be determined that m1=2, and the first interval is 3, so the first interval between the first two first repeated transmission resources is 3 repeated transmission resources, and thus, starting from the first repeated transmission resource, it is determined that the first two first repeated transmission resources are the first and fourth repeated transmission resources in the 10 repeated transmission resources; it can also be determined that m2=2, and the second interval is 2, so the second interval between the last two first repeated transmission resources is 2 repeated transmission resources, and thus, according to the first interval, the first repeated transmission resource of the last two first repeated transmission resources is determined to be the first repeated transmission resource in the 10 repeated transmission resources, and then, according to the second interval, the second repeated transmission resource of the last two first repeated transmission resources is determined to be the ninth repeated transmission resource in the 10 repeated transmission resources.

[0327] As can be seen, compared with Figure 6 , the distribution of the first repeated transmission resources in the at least two repeated transmission resources, in the case of the same number of first repeated transmission resources, by Figure 7 the allocation mode shown, the at least one first repeated transmission resource is divided into two parts, and the last first repeated transmission resource in the at least one first repeated transmission resource corresponds to two repeated transmission resources, so that the distribution of the first repeated transmission resources in the at least two repeated transmission resources is more uniform.

[0328] In addition, for the above two ways of determining the first repeated transmission resources, as shown in Figure 8 , the first repeated transmission resources with a relatively small interval can be placed in front of the at least two repeated transmission resources, and compared with Figure 6 , the last first repeated transmission resource in Figure 6 is placed at the front; compared with Figure 7 , the last two first repeated transmission resources with a small interval are placed in front. In this way, the density of the first repeated transmission resources in front of the at least two repeated transmission resources is higher, and in the case of fewer repeated transmission resources, more first repeated transmission resources can be obtained, which facilitates the receiving end to make some more accurate estimations, such as frequency offset estimation, statistical quantity estimation, and channel estimation, etc.

[0329] 503: The terminal device receives the repetitions of the reference signal and the downlink channel on the at least first repeated transmission resources, receives the repetitions of the downlink channel on the second repeated transmission resources, or transmits the repetitions of the reference signal and the uplink channel on the at least first repeated transmission resources, and transmits the repetitions of the uplink channel on the second repeated transmission resources.

[0330] Referring to Figure 9 , Figure 9 FIG. 6 shows a flowchart of another method for determining the position of a reference signal according to an embodiment of the present application. The same content as the embodiments shown in FIGS. 1-5 is not repeated here. The method of this embodiment includes the following steps: Figure 4 and Figure 5 The same content as the embodiments shown in FIGS. 1-5 is not repeated here. The method of this embodiment includes the following steps:

[0331] 901: The network device sends the terminal device the number of at least two repeated transmission resources and the interval between the nominal adjacent first repeated transmission resources.

[0332] The interval between the nominal adjacent first repeated transmission resources is the interval between any two adjacent first repeated transmission resources in the first repeated transmission resources in the normal position, which are the first repeated transmission resources in the at least one first repeated transmission resource that are not in the time domain edge position.

[0333] For example, as shown in FIG. 6, the interval between the nominal adjacent first repeated transmission resources is the interval between any two adjacent first repeated transmission resources in the first three first repeated transmission resources. Figure 6

[0334] Similarly, the interval can be the number of second repeated transmission resources between any two adjacent first repeated transmission resources in the first repeated transmission resources in the normal position, or the number of repeated transmission resources between the any two adjacent first repeated transmission resources, which includes the number of second repeated transmission resources between the any two adjacent first repeated transmission resources and one of the any two adjacent first repeated transmission resources.

[0335] 902: The terminal device determines the position of the at least one first repeated transmission resource in the at least two repeated transmission resources according to the number of the at least two repeated transmission resources and the interval between the nominal adjacent first repeated transmission resources.

[0336] For example, the terminal device takes the interval between the nominal adjacent first repeated transmission resources as the interval between any two adjacent first repeated transmission resources in the at least one first repeated transmission resource. Therefore, the terminal device can determine the position of the at least one first repeated transmission in the at least two repeated transmission resources according to the number of the at least two repeated transmission resources and the interval between the any two adjacent first repeated transmission resources. For specific determination of the position of the at least one first repeated transmission, please refer to the content in step 502, which is not described here.

[0337] ​For example, the terminal device determines the number of the at least one repetition transmission resource according to the number of the at least two repetition transmission resources and the interval between the nominal adjacent first repetition transmission resources.

[0338] For example, in the case that the interval between the nominal adjacent first repetition transmission resources is the number of the second repetition transmission resource between any two adjacent first repetition transmission resources in the first repetition transmission resources in the normal position, the number of the at least one repetition transmission resource can be represented by formula (5):

[0339]

[0340] wherein K is the number of the at least one repetition transmission resource, N is the number of the at least two repetition transmission resources, and L is the interval between the nominal adjacent first repetition transmission resources.

[0341] For example, in the case that the interval is the number of the repetition transmission resource between the any two adjacent first repetition transmission resources, the number of the at least one repetition transmission resource can be represented by formula (6):

[0342]

[0343] wherein K is the number of the at least one repetition transmission resource, N is the number of the at least two repetition transmission resources, and L is the interval between the nominal adjacent first repetition transmission resources.

[0344] Similarly, after determining the number of the at least one repetition transmission resource, the at least one first repetition transmission resource can be split into two parts, i.e., the at least one first repetition transmission resource includes the first n1 first repetition transmission resources and the last n2 first repetition transmission resources. Therefore, similar to step 502, the terminal device can determine the positions of the first n1 first repetition transmission resources in the at least two repetition transmission resources and the positions of the last n2 first repetition transmission resources in the at least two repetition transmission resources according to the number of the at least two repetition transmission resources and the number of the at least one repetition transmission resource, and the specific determination of the positions of the first repetition transmission resources can refer to the content in step 502, which will not be described herein.

[0345] The first repeated transmission resource of the at least two repeated transmission resources carries a demodulation reference signal, that is, the first first repeated transmission resource of the first n1 repeated transmission resources is the first repeated transmission resource of the at least two first repeated transmission resources. In addition, a third interval between any two adjacent first repeated transmission resources of the first n1 repeated transmission resources is different from a fourth interval between any two adjacent first repeated transmission resources of the second n2 repeated transmission resources, and an interval between a last first repeated transmission resource of the first n1 repeated transmission resources and a first first repeated transmission resource of the second n2 repeated transmission resources is the third interval.

[0346] 903: The terminal device receives a reference signal and a repetition of a downlink channel on the at least first repeated transmission resource, receives a repetition of the downlink channel on the second repeated transmission resource, or transmits a reference signal and a repetition of an uplink channel on the at least first repeated transmission resource, transmits a repetition of the uplink channel on the second repeated transmission resource.

[0347] Reference is made to Figure 10 , Figure 10 Another flowchart of a method for determining a position of a reference signal is provided in the embodiments of the present application. The embodiments in the present application are the same as those shown in the embodiments of Figure 4 、 Figure 5 and Figure 9 The method of the present embodiment includes the following steps:

[0348] 1001: The network device sends a terminal device a number of at least two repeated transmission resources and a nominal interval between adjacent first repeated transmission resources.

[0349] 1002: The network device sends a terminal device a first message, the first message being used to determine that a repeated transmission resource i of the at least two repeated transmission resources is cancelled.

[0350] The repeated transmission resource i can be any one of the at least two repeated transmission resources. In actual application, there can be multiple repeated transmission resources cancelled. In the present application, only one repeated transmission resource is cancelled as an example, and other cancelled cases can be referred to the case of one repeated transmission resource cancelled, which will not be described.

[0351] The repeated transmission resource i is cancelled, that is, a repeated transmission corresponding to the repeated transmission resource i is cancelled.

[0352] The network device sends a first message to the terminal device before the terminal device determines the position of the first repeated transmission resource according to the number of the at least two repeated transmission resources and the interval between the nominal adjacent first repeated transmission resources, and the first message indicates that the terminal device has a high-priority transmission between the at least two repeated transmissions, and the terminal device needs to interrupt the repeated transmission on the repeated transmission resource i. From the perspective of the terminal device, the terminal device knows in advance that part of the at least two repeated transmission resources is cancelled before determining the position of the first repeated transmission resource. Of course, in actual application, the terminal device can also not know in advance that part of the at least two repeated transmission resources is cancelled. Details about scenarios in which the terminal device can know in advance that the repeated transmission resource is cancelled and scenarios in which the terminal device cannot know in advance that the repeated transmission resource is cancelled are described below, and are not described in detail here.

[0353] 1003: The terminal device determines the position of the at least one first repeated transmission resource in the at least two repeated transmission resources according to the number of the at least two repeated transmission resources, the interval between the nominal adjacent first repeated transmission resources, and the repeated transmission resource i.

[0354] Because the terminal device knows in advance that the repeated transmission resource i is cancelled, for uplink transmission, the transmission phase corresponding to the two repeated transmission resources adjacent to the repeated transmission resource i is discontinuous or the difference of the transmission power is not within the first range configured by the network device, which causes the terminal device to use different channels when performing the two repeated transmissions, and the latter repeated transmission cannot use the former reference signal for channel estimation.

[0355] The first range can be (q1, q2), q1 is a negative number, q2 is a positive number, and the absolute values of q1 and q2 can be equal or unequal. That is, if the transmission power corresponding to the latter repeated transmission resource of the two repeated transmission resources adjacent to the repeated transmission resource i is greater than that of the former repeated transmission resource, the maximum difference of the transmission power allowed by the network device is q2, and if the difference exceeds q2, the terminal device can adjust the gain level and then use different channels for repeated transmission; if the transmission power corresponding to the latter repeated transmission resource of the two repeated transmission resources adjacent to the repeated transmission resource i is less than that of the former repeated transmission resource, the minimum difference of the transmission power allowed by the network device is q1, and if the difference is less than q1, the terminal device can adjust the gain level and then use different channels for repeated transmission.

[0356] Therefore, if the terminal device determines the position of the first repeated transmission resource according to the number of the at least two repeated transmission resources and the interval between the nominal adjacent first repeated transmission resources, the terminal device can know in advance that part of the at least two repeated transmission resources is cancelled. Figure 5 or Figure 9The embodiment shown determines the position of the first repetition transmission resource. Since the repetition transmission resource i is cancelled, it can result in that several repetitions after the repetition transmission resource i have no reference signal to use, which causes the terminal device to need to store the data received during this period, increasing the storage of the terminal device.

[0357] For example, as shown in Figure 11 As shown, according to the embodiment shown in Figure 5 or Figure 9 The embodiment shown determines the position of the first repetition transmission resource, and the terminal device can determine that the first repetition transmission resource, the sixth repetition transmission resource and the eleventh repetition transmission resource carry reference signals. If the seventh repetition transmission resource is not cancelled, the sixth to tenth repetition transmissions can all use the reference signal transmitted on the sixth repetition transmission resource for channel estimation. Since the seventh repetition transmission resource is cancelled, the sixth repetition transmission and the eighth repetition transmission use different channels, so the eighth repetition transmission cannot use the reference signal transmitted on the sixth repetition transmission resource for channel estimation, which causes the terminal device to need to store the data received between the eighth to tenth repetition transmissions, increasing the storage of the terminal device.

[0358] In addition, it is also possible that, according to the embodiment shown in Figure 5 or Figure 9 The embodiment shown determines the position of the first repetition transmission resource, which can result in that the determined repetition transmission resource i is a first repetition transmission resource, and the subsequent repetition transmissions can only use the reference signal transmitted on the first repetition transmission resource located before the repetition transmission resource i for channel estimation. However, this first repetition transmission resource can be far away from the subsequent repetition transmissions, and due to the change of the channel, the quality of the subsequent channel estimation can be poor.

[0359] Therefore, the terminal device determines the position of the first repetition transmission resource among the at least two repetition transmission resources according to the number of the at least two repetition transmission resources, the nominal interval between the adjacent first repetition transmission resources and the repetition transmission resource i, so that the distribution of the first repetition transmission resource is more reasonable.

[0360] For example, the terminal device determines a first number of uncancelled repeating resources following repeating resource i among the at least two repeating resources; based on the first number and the nominal interval between adjacent first repeating resources, it determines the position of the first repeating resource among the uncancelled repeating resources following repeating resource i. That is, it is equivalent to treating the uncancelled repeating resources following repeating resource i as multiple new repeating resources, and determining the position of the first repeating resource among these multiple new repeating resources based on the first number and the nominal interval. The determination method can be referred to... Figure 9 The embodiments described above will not be repeated.

[0361] For example, the terminal device determines a second number of uncancelled duplicate transmission resources preceding duplicate transmission resource i among the at least two duplicate transmission resources; based on the second number and the nominal interval between adjacent first duplicate transmission resources, it determines the position of the first duplicate transmission resource among the uncancelled duplicate transmission resources preceding duplicate transmission resource i. That is, it is equivalent to treating the uncancelled duplicate transmission resources preceding duplicate transmission resource i as multiple new duplicate transmission resources, and determining the position of the first duplicate transmission resource among these multiple new duplicate transmission resources based on the second number and the nominal interval. The determination method can be referred to... Figure 9 The implementation method described above will not be further elaborated.

[0362] For example, such as Figure 12 As shown, by taking repeating resource i into account to determine the location of the first repeating resource, the first, fourth, eighth, and twelfth repeating resources can be identified as the first repeating resource. It can be seen that the reference signal is directly carried in the first repeating resource that was not cancelled after the cancelled seventh repeating resource, namely the eighth repeating resource. The terminal device can then demodulate the data received between the eighth and eleventh repeating transmissions without requiring additional storage from the terminal device.

[0363] It should be noted that if duplicate transmission resource i is cancelled, the transmission phases corresponding to its two adjacent duplicate transmission resources may still be continuous, or the transmission power corresponding to the two adjacent duplicate transmission resources may also be within the first area configured by the network device. Therefore, the terminal device can use the same channel during the two duplicate transmissions corresponding to these two duplicate transmission resources. This means that duplicate transmission resource i has no impact on determining the position of the at least one duplicate transmission resource. Therefore, the terminal device can directly determine the position of the at least one duplicate transmission resource in the at least two duplicate transmissions based on the number of the at least two duplicate transmission resources and the nominal interval between adjacent first duplicate transmission resources. For specific implementation details, please refer to [reference needed]. Figure 9 The implementation method described above will not be further elaborated.

[0364] Furthermore, the continuity of the transmission phase or the transmission power within the first area configured by the network device can be determined autonomously by the terminal device or indicated by the network device. In the case where the terminal device determines this autonomously, it can be determined by the duration for which the repeated transmission resource i is cancelled; if this duration is less than a threshold, then it is determined that the resource can be used. Figure 9 The location of the first duplicated resource is determined directly using one method; otherwise, it is determined using... Figure 10 The method shown is used to determine the location of the first duplicate transmission resource. This application does not limit the implementation method of the terminal device. When indicated by the network device, this can be achieved through the first message itself. For example, if the network device sends the first message to the terminal device, it indicates that the transmission phase is continuous or the transmission power is within the first area configured by the network device. If the network device sends other messages to the terminal device to indicate that the duplicate transmission resource i has been cancelled, it indicates that the transmission phase is discontinuous or the transmission power is not within the first area configured by the network device. Of course, additional message signaling can also be used to directly indicate whether the transmission phase is continuous or whether the transmission power is within the first area configured by the network device. This application does not limit the indication method of the network device.

[0365] 1004: The terminal device receives a reference signal and a repeat of the downlink channel on the at least first repeat transmission resource, and receives a repeat of the downlink channel on the second repeat transmission resource; or, it transmits a reference signal and a repeat of the uplink channel on the at least one first repeat transmission resource, and transmits a repeat of the uplink channel on the second repeat transmission resource.

[0366] See Figure 13 , Figure 13 This is a flowchart illustrating another method for determining the position of a reference signal provided in an embodiment of this application. In this embodiment, [the method is related to...]. Figure 4 , Figure 5 , Figure 9 andFigure 10 The same content as the embodiments shown is not repeated here. The method of this embodiment includes the following steps:

[0367] 1301: The terminal device determines at least one first repetition transmission resource carrying a reference signal in at least two repetition transmission resources, wherein there is a second repetition transmission resource not carrying a reference signal in the at least two repetition transmission resources.

[0368] Wherein, the position of the first repetition transmission resource can be determined according to the number of the at least two repetition transmission resources and the number of the at least one repetition transmission, or according to the number of the at least two repetition transmission resources and the interval between the nominal adjacent first repetition transmission resources, which can be referred to the above Figure 5 Or Figure 9 The implementation process in the embodiments shown is not described.

[0369] Of course, before the terminal device determines at least one first repetition transmission resource carrying a reference signal in at least two repetition transmission resources, the terminal device can have received a first message sent by the network device, and according to the first message, it is determined that the repetition transmission resource i is cancelled, and then according to the repetition transmission resource i, the number of the at least two repetition transmission resources and the interval between the nominal adjacent first repetition transmission resources, the position of the first repetition transmission resource is determined. For specific implementation, please refer to the process shown in the embodiment of Figure 10 .

[0370] 1302: The network device sends a second message to the terminal device, and the second message is used to determine that the repetition transmission resource j in the at least two repetition transmission resources is cancelled.

[0371] That is, after the terminal device determines the position of the first repetition transmission resource in the at least two repetition transmission resources, the second message is sent to the terminal device, which indicates that the terminal device has a high priority transmission, and then determines that the repetition transmission resource j in the at least two repetition transmission resources is cancelled. From the perspective of the terminal device, the terminal device cannot predict in advance which repetition transmission resource is cancelled.

[0372] 1303: The terminal device adjusts the position of the at least one first repetition transmission resource in the at least two repetition transmission resources according to the repetition transmission resource j.

[0373] The terminal device has determined the position of the first repetition transmission resource before receiving the second message, but due to the repetition transmission resource j being cancelled, the two repetition transmissions adjacent to the repetition transmission resource j can use different channels; it is also possible that the repetition transmission resource j itself is a first repetition transmission resource, and the repetition transmission resource j is cancelled, which causes the subsequent repetition transmission to be able to use only the reference signal transmitted on the first repetition transmission resource before the repetition transmission resource j for channel estimation. However, this first repetition transmission resource can be far away from the subsequent repetition transmission, and due to the change of the channel, the quality of the subsequent channel estimation can be poor. Therefore, the position of the first repetition transmission resource can be adjusted.

[0374] In addition, in order to avoid increasing the storage of the receiving end, the first repetition transmission resource in the repetition transmission resources after the repetition transmission resource j carries the reference signal.

[0375] For example, the terminal device determines a third quantity of the repetition transmission resources after the repetition transmission resource j and not cancelled, and a fourth quantity of the first repetition transmission resource after the repetition transmission resource j and not cancelled; and then determines the position of the first repetition transmission resource in the repetition transmission resources after the repetition transmission resource j and not cancelled according to the third quantity and the fourth quantity, wherein the first repetition transmission resource in the repetition transmission resources after the repetition transmission resource j and not cancelled carries the reference signal.

[0376] The determination process of the position of the first repetition transmission resource in the repetition transmission resources after the repetition transmission resource j and not cancelled according to the third quantity and the fourth quantity will be described in detail later, and will not be described here.

[0377] Since the terminal device cannot predict in advance which repetition transmission resource is cancelled, and it takes a period of time for the terminal device to prepare data, if the terminal device wants to adjust the position of the first repetition transmission resource in the repetition transmission resources after the repetition transmission resource j and not cancelled, it can ensure that the terminal device is ready to prepare data. Therefore, the terminal device first determines whether the first time interval is greater than a first threshold, and then determines the third quantity and the fourth quantity to adjust the position of the first repetition transmission resource in the case where the first time interval is greater than or equal to the first threshold.

[0378] The first threshold is determined according to the preparation time of the terminal device for data transmission, the first time interval is the time interval between the first time and the second time, the first time is the start time of the repetition transmission resource after the repetition transmission resource j and not cancelled, the second time is the end time of the terminal device receiving the second message, and the second time is later than the first time.

[0379] In addition, in the case that the first time interval is less than the first threshold, the terminal device receives the second message too late, in other words, the terminal device receives the second message too close to the start time of the non-canceled repetition transmission resource after the repetition transmission resource j, which can cause the terminal device to not have enough time to prepare data for the first repetition transmission resource after the repetition transmission resource j. Therefore, even if the position of the first repetition transmission resource is adjusted so that the reference signal is carried on the first repetition transmission resource after the repetition transmission resource j, the reference signal is useless. In this case, the terminal device can not adjust the position of the first repetition transmission resource, and perform repetition transmission according to the position of the first repetition transmission resource determined before; or give up the repetition transmission after the repetition transmission resource j.

[0380] For example, as shown in FIG. 7, it is assumed that the first threshold is T1, and the seventh repetition transmission resource is canceled, and the start time of the first repetition transmission resource after the seventh repetition transmission resource is t2; if the terminal device receives the second message before t4, the terminal device has enough time to prepare data for the eighth repetition transmission resource, at which time the position of the first repetition transmission resource in the repetition transmission resources after the seventh repetition transmission resource can be re-determined so that the eighth repetition transmission resource carries the reference signal. If the terminal device receives the second message after t4, the terminal device does not have enough time to prepare data for the eighth repetition transmission resource, and the terminal device can perform repetition transmission using the first repetition transmission resource determined before the adjustment, or give up the repetition transmission resources after the seventh repetition transmission resource. Figure 14

[0381] It should be noted that whether the first time interval of the terminal device is greater than the first threshold can be implemented by the network device. Specifically, the network device autonomously determines whether the position of the first repetition transmission resource in the non-canceled repetition transmission resources after the repetition transmission resource j can be adjusted at present, and if so, sends the second message to the terminal device, and indicates to the terminal device through the second message itself that the position of the first repetition transmission resource in the non-canceled repetition transmission resources after the repetition transmission resource j can be adjusted; or indicates whether the position of the first repetition transmission resource in the non-canceled repetition transmission resources after the repetition transmission resource j can be adjusted through other messages. The implementation of the network device is not limited in the present application.

[0382] ​In addition, the cancellation of the repetition transmission resource j also causes the allocation of the first repetition transmission resource in the non-canceled repetition transmission resources before the repetition transmission resource j to be no longer uniform. Therefore, the terminal device can adjust the position of the first repetition transmission resource in the non-canceled repetition transmission resources before the repetition transmission resource j.

[0383] It can be understood that although the terminal device cannot predict in advance that the repetition transmission resource j is canceled, if the terminal device receives the second message very early, and if the terminal device has not performed a repetition transmission at this time, the terminal device can adjust the position of the first repetition transmission resource in the non-canceled repetition transmission resources before the repetition transmission resource j.

[0384] For example, the fifth quantity of the non-canceled repetition transmission resources before the repetition transmission resource j and the sixth quantity of the first non-canceled repetition transmission resource before the repetition transmission resource j are determined, and the position of the first repetition transmission resource in the non-canceled repetition transmission resources before the repetition transmission resource j is determined according to the fifth quantity and the sixth quantity, wherein the first repetition transmission resource in the non-canceled repetition transmission resources before the repetition transmission resource j carries a demodulation reference signal.

[0385] The position of the first repetition transmission resource in the non-canceled repetition transmission resources before the repetition transmission resource j is determined according to the fifth quantity and the sixth quantity, which will be described in detail later.

[0386] Similarly, to adjust the position of the first non-canceled repetition transmission resource before the repetition transmission resource j, the terminal device first determines whether the second time interval is greater than the first threshold value, and if it is determined that the second time interval is greater than or equal to the first threshold value, the fifth quantity and the sixth quantity are determined to adjust the position of the first repetition transmission resource in the non-canceled repetition transmission resources before the repetition transmission resource j.

[0387] The first threshold value is determined according to the preparation time of the terminal device for data transmission, the second time interval is the time interval between the second time and the third time, the second time is the end time of the terminal device receiving the second message, and the second time is earlier than the third time, and the third time is the start time of the first repetition transmission resource in the at least two repetition transmission resources.

[0388] It is understandable that if the second time interval is less than the first threshold, and the position of the first, uncancelled, duplicated resource preceding duplicated resource j is readjusted, the terminal device cannot prepare data for the repositioned duplicated resource. Therefore, in this case, the position of the first, uncancelled, duplicated resource preceding duplicated resource j cannot be readjusted, and duplicated transmission can be performed using the previously determined position of the first duplicated resource.

[0389] For example, such as Figure 14 As shown, because the seventh duplicate transmission resource is cancelled, the distribution of the first duplicate transmission resource among the duplicate transmission resources preceding the seventh duplicate transmission resource is no longer uniform. For example, the first duplicate transmission resource corresponds to five duplicate transmission resources, while the second duplicate transmission resource corresponds to one duplicate transmission resource. Therefore, if the terminal device receives the second message before t3, the interval between the end time of receiving the second message and the start time of the first duplicate transmission resource is greater than the first threshold. In other words, the terminal device still has time to prepare data for the first duplicate transmission resource. Thus, even after adjusting the position of the first duplicate transmission resource among the uncancelled duplicate transmission resources preceding duplicate transmission resource j, there is still sufficient time to prepare data. Therefore, the position of the uncancelled first duplicate transmission resource preceding duplicate transmission resource j can be adjusted to make the distribution of the first duplicate transmission resource more uniform. If the terminal device receives the second message between t3 and t1, since there is not enough time to prepare data for the first duplicate transmission resource, the position of the uncancelled first duplicate transmission resource preceding duplicate transmission resource j cannot be adjusted. In this case, the duplicate transmission resource before adjustment can be used for duplicate transmission. Of course, if the terminal device receives the second message between t1 and t4, then the portion of the repeat transmission resources before repeat transmission resource j has already been consumed. In this case, it is even more impossible to adjust the position of the first repeat transmission resource that has not been canceled before repeat transmission resource j.

[0390] It should be noted that the method by which the second time interval of the terminal device is greater than the first threshold can be implemented by the network device. Specifically, the network device autonomously decides whether the position of the first repeated transmission resource among the uncancelled repeated transmission resources preceding repeated transmission resource j can be adjusted. If it can, the network device sends a second message to the terminal device, indicating to the terminal device through the second message itself that the position of the first repeated transmission resource among the uncancelled repeated transmission resources preceding repeated transmission resource j can be adjusted; or, it indicates whether the position of the first repeated transmission resource among the uncancelled repeated transmission resources preceding repeated transmission resource j can be adjusted through other messages. This application does not limit the implementation method of the network device.

[0391] The following describes how to determine the position of the first repetition transmission resource among the non-canceled repetition transmission resources before and after the repetition transmission resource j.

[0392] For example, the fifth quantity and the sixth quantity are respectively taken as a new quantity of repetition transmission resources and a new quantity of first repetition transmission resources, and the position of the first repetition transmission resource among the non-canceled repetition transmission resources before the repetition transmission resource j is determined according to the new quantity of repetition transmission resources and the new quantity of first repetition transmission resources.

[0393] For example, if The third quantity is taken as a new quantity of repetition transmission resources, the sixth quantity is taken as a new quantity of first repetition transmission resources, and the position of the first repetition transmission resource among the non-canceled repetition transmission resources after the repetition transmission resource j is determined according to the new quantity of repetition transmission resources and the new quantity of first repetition transmission resources. Wherein, KK2 is the fourth quantity, and N2 is the third quantity; if The third quantity is taken as a new quantity of repetition transmission resources, the sixth quantity is taken as a new quantity of first repetition transmission resources, and the position of the first repetition transmission resource among the non-canceled repetition transmission resources after the repetition transmission resource j is determined according to the new quantity of repetition transmission resources and the new quantity of first repetition transmission resources. Wherein, KK2 is the fourth quantity, and N2 is the third quantity; if

[0394] Wherein, the implementation of determining the position of the first repetition transmission resource according to the quantity of repetition transmission resources and the quantity of first repetition transmission resources can refer to the above process, and will not be described again.

[0395] In addition, if the terminal device receives the nominal interval between adjacent first repetition transmission resources sent by the network device, only the third quantity of non-canceled repetition transmission resources after the repetition transmission resource j can be obtained, and then the position of the first repetition transmission resource among the non-canceled repetition transmission resources before the repetition transmission resource j is determined according to the third quantity and the nominal interval between adjacent first repetition transmission resources. Of course, only the fifth quantity of non-canceled repetition transmission resources before the repetition transmission resource j can be obtained, and then the position of the first repetition transmission resource among the non-canceled repetition transmission resources before the repetition transmission resource j is determined according to the fifth quantity and the nominal interval between adjacent first repetition transmission resources.

[0396] Wherein, the way of determining the position of the first repetition transmission resource according to the quantity of repetition transmission resources and the nominal interval between adjacent first repetition transmission resources can refer to the above implementation process, and will not be described again.

[0397] In some possible implementation manners, although the repetition transmission resource j is cancelled, the transmission phase after being cancelled can also be continuous or the transmission power is also within the first range configured by the network device, so that the terminal device does not need to adjust the position of the first repetition transmission resource. Therefore, the position of the at least one first repetition transmission resource in the at least two repetition transmission resources is adjusted only in a case where it is determined that the transmission phase of the nearest one of the repetition transmission resources before the repetition transmission resource j and the nearest one of the repetition transmission resources after the repetition transmission resource j is discontinuous, or in a case where it is determined that the transmission power of the nearest one of the repetition transmission resources before the repetition transmission resource j and the nearest one of the repetition transmission resources after the repetition transmission resource j is different from the first range configured by the network device, otherwise, the position of the at least one first repetition transmission resource in the at least two repetition transmission resources is not adjusted.

[0398] It should be noted that whether the transmission phase is continuous or the transmission power is within the first range can be implemented by the network device. The determination can be made by the terminal device autonomously or can be indicated by the network device. Specifically, in a case where the determination is made by the terminal device autonomously, the duration for which the repetition transmission resource j is cancelled can be used to determine whether the transmission phase is continuous, if the duration is less than a threshold, it is determined that the transmission phase is continuous, otherwise, the transmission phase is discontinuous; in a case where the determination is made by the network device, the second message itself can be used to implement the determination, for example, if the network device sends the second message to the terminal device, it indicates that the transmission phase is continuous, if the network device sends other messages to the terminal device to indicate that the repetition transmission resource j is cancelled, it indicates that the transmission phase is discontinuous or the transmission power is not within the first range configured by the network device; of course, other messages can also be used to directly indicate whether the transmission phase is continuous or the transmission power is within the first range configured by the network device. The application does not limit the indication manner of the network device.

[0399] 1304: The terminal device receives a reference signal and a repetition of a downlink channel on the at least first repetition transmission resource, receives the repetition of the downlink channel on the second repetition transmission resource, or transmits a reference signal and a repetition of an uplink channel on the at least one first repetition transmission resource, transmits the repetition of the uplink channel on the second repetition transmission resource.

[0400] In addition, in the case of channel slowly changing, another DM-RS less technology is also proposed, the main idea of which is that the sending end transmits high-density DM-RS on some repetition corresponding repetition transmission resources and transmits low-density DM-RS on some repetition corresponding repetition transmission resources, so that the receiving end can use the high-density DM-RS for accurate channel estimation, use the low-density DM-RS for rough channel estimation, and combine the high-density DM-RS and the low-density DM-RS for joint channel estimation to meet different channel estimation requirements. For example, the high-density DM-RS is compared with the low-density DM-RS, the number of repetition transmission resources used to carry the high-density DM-RS is more than the number of repetition transmission resources used to carry the low-density DM-RS, and it can also be understood that the number of DM-RS transmitted on the repetition transmission resources of the high-density DM-RS is more than the number of DM-RS transmitted on the repetition transmission resources of the low-density DM-RS.

[0401] As shown in Figure 15 , the sending end can transmit high-density DM-RS on the repetition transmission resources corresponding to the first and third repetitions and transmit low-density DM-RS on the repetition transmission resources corresponding to the second and fourth repetitions.

[0402] However, this DM-RS less technology will cause some repetition corresponding repetition transmission resources to carry high-density DM-RS and some repetition corresponding repetition transmission resources to carry low-density DM-RS. Therefore, this DM-RS less technology will also change the correspondence between DM-RS and repetition, how the network device indicates the position of the high-density DM-RS and the position of the low-density DM-RS, and how the terminal device determines the position of the high-density DM-RS and the low-density DM-RS in multiple repetitions are currently in the blank stage.

[0403] Therefore, in order to solve the problem that the high-density DM-RS and the low-density DM-RS cannot be determined in multiple repetitions caused by the above DM Less technology, the embodiment of the present application provides a reference signal position determination method.

[0404] Referring to Figure 16 , Figure 16 Another flowchart of the reference signal position determination method provided by the embodiment of the present application is provided. The method comprises the following steps:

[0405] 1601: The terminal device determines at least one first repetition transmission resource carrying reference signals from at least two repetition transmission resources, wherein there is a second repetition transmission resource carrying reference signals in the at least two repetition transmission resources, and the number of repetition transmission resources for carrying reference signals in each of the at least one first repetition transmission resource is greater than the number of repetition transmission resources for carrying reference signals in the second repetition transmission resource.

[0406] The manner of determining the at least one first repetition transmission resource carrying reference signals from the at least two repetition transmission resources is similar to the manner of determining the at least one first repetition transmission resource shown in the above Figure 4 , Figure 5 , Figure 9 and Figure 10 , and will not be described again.

[0407] Generally, the number of repetition transmission resources for carrying reference signals in any two first repetition transmission resources is the same, and the number of repetition transmission resources for carrying reference signals in any two second repetition transmission resources is also the same. Of course, in actual application, the number of repetition transmission resources for carrying reference signals in any two first repetition transmission resources can be designed to be different, and the number of repetition transmission resources for carrying reference signals in any two second repetition transmission resources can be designed to be different, but the number of repetition transmission resources for carrying reference signals in any one first repetition transmission resource is greater than the number of repetition transmission resources for carrying reference signals in the second repetition transmission resource.

[0408] Further, the repetition transmission resources for carrying DM-RS include frequency domain resources and time domain resources. Therefore, the number of repetition transmission resources for carrying high-density DM-RS is greater than the number of repetition transmission resources for carrying low-density DM-RS mainly includes the following examples:

[0409] Example 1: If the number of frequency domain resources for carrying high-density DM-RS and the number of frequency domain resources for carrying low-density DM-RS are the same, the number of OFDM symbols for carrying high-density DM-RS is greater than the number of OFDM symbols for carrying low-density DM-RS;

[0410] Example 2: If the number of time domain resources for carrying high-density DM-RS and the number of time domain resources for carrying low-density DM-RS are the same, the number of resource elements (REs) for carrying high-density DM-RS is greater than the number of REs for carrying low-density DM-RS;

[0411] Example 3: the number of OFDM symbols used to carry high-density DM-RS is greater than the number of OFDM symbols used to carry low-density DM-RS, and the number of REs used to carry high-density DM-RS is greater than the number of REs used to carry low-density DM-RS.

[0412] Therefore, for the present application, the number of repetition transmission resources used to carry reference signals in the first repetition transmission resources is greater than the number of repetition transmission resources used to carry reference signals in the second repetition transmission resources mainly includes the following cases:

[0413] Case 1: if the number of time-domain resources used to carry reference signals in the first repetition transmission resources is the same as the number of time-domain resources used to carry reference signals in the second repetition transmission resources, the number of OFDM symbols used to carry reference signals in the first repetition transmission resources is greater than the number of OFDM symbols used to carry reference signals in the second repetition transmission resources;

[0414] Case 2: if the number of frequency-domain resources used to carry reference signals in the first repetition transmission resources is the same as the number of frequency-domain resources used to carry reference signals in the second repetition transmission resources, the number of REs used to carry reference signals in the first repetition transmission resources is greater than the number of REs used to carry reference signals in the second repetition transmission resources;

[0415] Case 3: the number of OFDM symbols used to carry reference signals in the first repetition transmission resources is greater than the number of OFDM symbols used to carry reference signals in the second repetition transmission resources, and the number of REs used to carry reference signals in the first repetition transmission resources is greater than the number of REs used to carry reference signals in the second repetition transmission resources.

[0416] 1602: the terminal device receives repetitions of reference signals and downlink channels on the at least one first repetition transmission resource, receives repetitions of downlink channels on the second repetition transmission resource, or the terminal device transmits repetitions of reference signals and uplink channels on the at least one first repetition transmission resource, transmits repetitions of uplink channels on the second repetition transmission resource.

[0417] As can be seen from the embodiments of this application, during repeated transmission, relatively fewer resources can be used to carry reference signals on some repeated transmission resources, eliminating the need to carry a large number of reference signals on every repeated transmission resource. Furthermore, this transmission mode allows for precise determination of which repeated transmission resources carry relatively more reference signals and which carry relatively fewer, filling a gap in the prior art. In addition, using relatively fewer resources to carry reference signals on some repeated transmission resources for repeated transmission saves resources that can be used for data transmission compared to existing repeated transmission methods, improving communication efficiency with network devices.

[0418] It should be understood that, regarding the DM-RS Less technology in this embodiment, after the terminal device determines the locations of the high-density DM-RS and the low-density DM-RS, there may be situations where duplicate transmission resources are cancelled. For example, duplicate transmission resource i may be cancelled. Due to the cancellation of duplicate transmission resources, duplicate transmissions following duplicate transmission resource i may not have high-density DM-RS for accurate channel estimation. For instance, several duplicate transmission resources following duplicate transmission resource i may be second duplicate transmission resources. In this case, only the low-density DM-RS carried by the second duplicate transmission resource can be used for coarse channel estimation. If the receiver wants to perform accurate channel estimation at this time, it needs to wait for the arrival of the next duplicate transmission resource carrying high-density DM-RS. During the waiting period, the data of duplicate transmissions received during the waiting period needs to be stored, increasing the storage of the receiver. Therefore, compared with the above... Figure 10 Similar to the method shown, when duplicate transmission resources are cancelled, the positions of the first and second duplicate transmission resources can be adjusted to reduce the storage at the receiving end. The adjustment method is the same as... Figure 10 The adjustment method shown in the figure is similar, that is, respectively... Figure 16 The first repeated transmission resource mentioned in the corresponding embodiment is as Figure 10 The first duplicate transmission resource in the first duplicate transmission resource, and the second duplicate transmission resource as Figure 10 The second duplicate resource in the document will not be described further.

[0419] The following describes how to determine the location of the first duplicate transmission resource in a special high-priority transmission scenario.

[0420] Specifically, in the case that the high priority transmission is uplink configured grant transmission, the uplink resource is reserved for the uplink configured grant transmission, but it is not determined whether the terminal device will perform uplink transmission. Therefore, in the process of repeated transmission using DM-RS less technology, the uplink configured grant transmission can be processed by another processing. The other processing includes the following two processing methods:

[0421] For example, if the terminal device receives the network device indication that the high priority transmission is uplink configured grant transmission, it is determined that the uplink configured grant transmission cannot cancel the repeated transmission, that is, the uplink configured grant transmission will not cancel any one of the repeated transmission resources. Therefore, the terminal device can determine the position of the first repeated transmission resource according to the embodiments shown in Figure 5 or Figure 9 .

[0422] For example, if the terminal device has the opportunity to perform uplink transmission, it determines the position of the first repeated transmission resource according to the embodiments shown in Figure 10 or Figure 13 ; if the terminal device does not have the opportunity to perform uplink transmission, it determines the position of the first repeated transmission resource according to the embodiments shown in Figure 5 or Figure 9 .

[0423] Finally, refer to Table 1, which lists in detail the scenarios in which the terminal device can predict in advance whether the repeated transmission resource is canceled, and whether the terminal device's transmission phase is continuous in the case that the repeated transmission resource is canceled.
