Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, fig. 1 is a flowchart of a transmission method provided in an embodiment of the present invention, where the transmission method is used for a sending end device, where the sending end device is a network side device or a terminal, and as shown in fig. 1, the method includes the following steps:

step 101, repeatedly transmitting N physical shared channels; n is an integer greater than 1;

The physical shared channel may be a physical uplink shared channel PUSCH or a physical downlink shared channel PDSCH. Specifically, when the sending end device is a network side device, the repeatedly transmitting N physical shared channels may be repeatedly transmitting N PDSCHs to a terminal, and when the sending end device is a terminal, the repeatedly transmitting N physical shared channels may be repeatedly transmitting N PUSCHs to the network side device.

For the PUSCH, the method of the embodiment of the present invention is applicable to both the PUSCH based on the uplink grant and the PUSCH based on the configuration grant, and in the following description, the PUSCH generally refers to both types of PUSCHs.

It should be understood that the N physical shared channels of the above-mentioned repeated transmission may be distributed over 1 time slot, or may be distributed over a plurality of time slots.

In the embodiment of the invention, the physical shared channel can be a shared channel based on non-time slot scheduling, and the shared channel based on non-time slot scheduling can be transmitted for multiple times in one time slot, and the transmission can be positioned in multiple time slots, so that the problem of transmission conflict is more prominent, and the problem of transmission conflict can be better solved by using the method of the embodiment of the invention.

In this embodiment, the mapping policy from the repeatedly transmitted physical shared channel to the transmission resource includes two requirements:

1. in the time domain, the transmission resources of any one of the repeatedly transmitted N physical shared channels are continuously distributed in the time domain;

2. in the time domain, the transmission resource of any one of the repeatedly transmitted N physical shared channels is located in the same time slot.

In other words, the transmission resources of any one physical shared channel are neither separable nor cross-slotted.

Hereinafter, repeated transmission of the PUSCH is exemplified.

As shown in fig. 2a, taking the example of repeated transmission of 4 PUSCHs, the starting symbol of the repeated transmission is assumed to be symbol No. 8 in the first slot (slot n). At this time, any PUSCH needs to be continuously distributed in the time domain and located in the same time slot. Thus, the first 3 PUSCHs can be transmitted in the first slot (slot n), in

symbols

8, 9, 10, 11 and 12, 13 respectively, while the 4 th PUSCH is transmitted in

symbols

2,3 in the second slot (slot n + 1). Each PUSCH is continuously distributed in the time domain and located in the same slot. The time domain length of one PUSCH is 2, F represents a flexible symbol, U represents an uplink symbol, and D represents a downlink symbol.

As also shown in fig. 2b, for example, 4 PUSCHs are repeatedly transmitted, and the starting symbol of the repeated transmission is symbol No. 7 in slot n. At this time, the 1 st PUSCH, the 2 nd PUSCH and the 3rd PUSCH are transmitted in the 7 th, 8 th, 9 th, 10 th and 11 th, 12 th symbols of the first slot (slot n), respectively. Because only one uplink symbol is left in the first slot for transmission, if the 13 th symbol is allocated to the 4 th PUSCH, the transmission resource of the 4 th PUSCH inevitably has the phenomena of cross-slot and discontinuity, and the mapping strategy is not satisfied. Therefore, in the embodiment of the present invention, the 4 th PUSCH can only be transmitted in the

symbols

2 and 3 of the second slot (slot n + 1).

As shown in fig. 2c, for example, 4 PUSCHs are repeatedly transmitted, and the starting symbol of the repeated transmission is symbol No. 2 in the second slot (slot n + 1). At this time, the 1 st PUSCH, the 2 nd PUSCH, and the 3rd PUSCH are transmitted in the 2 nd, 3rd symbol, and the 4 th, 5 th symbol, respectively, of the second slot (slot n + 1). If the No. 6 symbol is allocated to the third PUSCH, the transmission resource of the third PUSCH is necessarily discontinuous, and the mapping strategy is not satisfied. Therefore, in the embodiment of the present invention, the 3rd PUSCH and the 4 th PUSCH can only be transmitted in the 10 th to 13 th symbols of the second slot (slot n + 1).

In this way, when the sending end device and the receiving end device transmit the physical shared channel, the sending end device may perform repeated transmission according to the rule that the transmission resource of any one of the physical shared channels specified in this embodiment needs to satisfy, so as to solve the problem of transmission collision occurring in the repeated transmission.

The above description is made by taking PUSCH as an example, but the same is applied to transmission of PDSCH, and the difference is only in the direction of transmission resources, and the description is not repeated here.

Under the condition that the sending end equipment is a terminal, before repeatedly transmitting N physical shared channels, the sending end equipment can also receive repeated transmission indication information from network side equipment, wherein the repeated transmission indication information comprises a time domain starting position S, the length L of the physical shared channel and the N;

and determining the transmission resources of the N physical shared channels in the time domain according to the S, L, N and the time slot format indication information.

In this embodiment, when the sending end device is a terminal, the network side device may first send repeat transmission indication information to the terminal to indicate a time domain starting position S, a length L of a physical shared channel, and a number N of physical shared channels when the terminal performs repeat transmission, so that the terminal may determine time domain resource distribution conditions of the N physical shared channels according to the S, L, N, a known time slot format (i.e., a symbol at each position in each time slot), and a rule that needs to be satisfied by a transmission resource of any one physical shared channel, and may further perform repeat transmission according to the determined time domain resource distribution conditions.

For example, if the received retransmission indication information sent by the network side device is S-8, L-2, and N-4, and the known slot format is as shown in fig. 2a, it may be determined that the time domain resource distribution of 4 PUSCHs to be retransmitted is: the 1 st PUSCH is transmitted by the

symbols

8 and 9 in the first time slot, the 2 nd PUSCH is transmitted by the

symbols

10 and 11 in the first time slot, the 3rd PUSCH is transmitted by the

symbols

12 and 13 in the first time slot, and the 4 th PUSCH is transmitted by the

symbols

2 and 3 in the second time slot.

Compared with the mode of directly indicating the time domain transmission resource of each PUSCH, the mode only needs to indicate the time domain starting position S of the transmission resource of the first PUSCH, the length L of the physical shared channel and the number N of the physical shared channels, so that the overhead of the repeated indication information can be greatly reduced, and the transmission resource is saved.

Optionally, a time difference between a starting time of the first transmission resource and an ending time of the second transmission resource is less than or equal to a first threshold, where the first transmission resource is: in the N physical shared channels, the second transmission resource is a starting symbol of a first physical shared channel: an ending symbol of a last physical shared channel among the N physical shared channels;

or

The transmission resources of the N physical shared channels are positioned in the same transmission period;

or

A time difference between an ending time of a third transmission resource and a starting time of a fourth transmission resource is less than or equal to a second threshold, and the third transmission resource is: in the adjacent physical shared channels, the fourth transmission resource is an end symbol of a previously transmitted physical shared channel: among the adjacent physical shared channels, the starting symbol of the physical shared channel transmitted later.

When the N physical shared channels are repeatedly transmitted, in order to ensure that the repeatedly transmitted physical shared channels meet a preset time limit rule, one or more of the N physical shared channels may be discarded in the transmission time sequence. Specifically, different processing may be performed according to the following three cases, respectively:

a first case is that, in a case where a duration from a start time of a start symbol of a first transmission to an end time of an end symbol of a last transmission is not expected to exceed a preset time interval, a time difference between the start time of the first transmission resource and the end time of the second transmission resource is less than or equal to a first threshold. The first transmission resource is a start symbol of a first physical shared channel of the N physical shared channels, the second transmission resource is an end symbol of a last physical shared channel of the N physical shared channels, and the first threshold may be a predefined time interval. When the time difference between the starting time of the first transmission resource and the ending time of the second transmission resource is greater than the first threshold, the transmission resources whose time domain positions in the N physical shared channels exceed the first threshold range may be discarded.

For example, as shown in fig. 3a, the time domain length Q of the first threshold is 16 symbols, and in 4 physical shared channels to be repeatedly transmitted, the difference between the starting time of the starting symbol of the first physical shared channel and the receiving time of the ending symbol of the fourth physical shared channel is 18 symbols, which exceeds the length specified by the first threshold. Therefore, in the embodiment of the present invention, the transmission resource of the fourth physical shared channel may be discarded, and the time difference between the starting time of the starting symbol of the first physical shared channel and the ending time of the ending symbol of the third physical shared channel is 16 symbols, which does not exceed the length of the first threshold, so that the resource transmission from the first physical shared channel to the third physical shared channel may be reserved.

The above strategy may be controlled by the sending end device, for example, whether transmission is needed is determined before each PUSCH is transmitted. Taking repeated transmission of 4 PUSCHs as an example, as shown in fig. 3a, before the second PUSCH is transmitted, it is determined whether the time difference between the starting time of the first transmission resource (symbol No. 10 in slot n) and the ending time of the second transmission resource (symbol No. 13 in slot n) exceeds the Q value, and if the determination result indicates that the time difference does not exceed the Q value, the transmission is continued. And when the fourth PUSCH is transmitted, judging whether the time difference between the starting time of the first transmission resource (the 10 th symbol in the time slot n) and the ending time of the second transmission resource (the 13 th symbol in the time slot n +1) exceeds the Q value, and if the judgment result indicates that the time difference exceeds the Q value, discarding the fourth PUSCH.

In the second case, when the transmission resources of the N physical shared channels are expected to be located in the same transmission period, the physical shared channel exceeding the transmission period in the N physical shared channels may be discarded. Wherein the transmission period may be preconfigured. For example, as shown in fig. 3b, when the first to third physical shared channels of the 4 physical shared channels to be repeatedly transmitted are all located in the same transmission period P, and the fourth physical shared channel is not completely located in the transmission period, the fourth physical shared channel may be discarded to ensure that the repeatedly transmitted physical shared channels are all located in the same transmission period.

The above strategy may be controlled by the sending end device, for example, whether transmission is needed is determined before each PUSCH is transmitted. Taking repeated transmission of 4 PUSCHs as an example, as shown in fig. 3b, before the second PUSCH is transmitted, it is determined whether the end symbol (symbol No. 5 in slot n +1) of the second PUSCH is located in the period P, and if the determination result indicates that the end symbol is located in the period P, the transmission is continued. And when the fourth PUSCH is transmitted, judging whether the ending symbol (No. 13 symbol in the time slot n +1) of the fourth PUSCH is positioned in the period P or not, and discarding the fourth PUSCH if the judgment result indicates that the ending symbol is not positioned in the period P.

In a third case, when the time interval of the transmission resources of the adjacent physical shared channel is not expected to exceed the preset interval, it is specified that a time difference between an end time of a third transmission resource and a start time of a fourth transmission resource is less than or equal to a second threshold, where the third transmission resource is an end symbol of a previously transmitted physical shared channel in the adjacent physical shared channel, the fourth transmission resource is a start symbol of a subsequently transmitted physical shared channel in the adjacent physical shared channel, and the second threshold may be a predefined time interval. When the time difference between the third transmission resource and the fourth transmission resource is greater than the second threshold, the physical shared channel resource located after the third transmission resource among the N physical shared channels may be discarded.

For example, as shown in fig. 3c, the time domain length O of the second threshold is 9 symbols, and the time domain interval between the end time of the end symbol of the second physical shared channel and the start time of the start symbol of the third physical shared channel in 4 physical shared channels to be repeatedly transmitted is 10 symbols, which exceeds the interval length specified by the second threshold, so that the third physical shared channel and the fourth physical shared channel can be discarded, and only the first physical shared channel and the second physical shared channel are reserved.

The above strategy may be controlled by the sending end device, for example, whether transmission is needed is determined before each PUSCH is transmitted. Taking repeated transmission of 4 PUSCHs as an example, as shown in fig. 3c, before the second PUSCH is transmitted, it is determined whether the time difference between the starting time of the third transmission resource (symbol 11 in slot n) and the ending time of the fourth transmission resource (symbol 12 in slot n) exceeds the O value, and if the determination result indicates that the time difference does not exceed the O value, the transmission is continued. And when the third PUSCH is transmitted, judging whether the time difference between the starting time of the third transmission resource (the No. 13 symbol in the time slot n) and the ending time of the fourth transmission resource (the No. 10 symbol in the time slot n +1) exceeds the O value, if the judgment result indicates that the time difference exceeds the O value, discarding the third PUSCH and the fourth PUSCH.

In this way, in this embodiment, the specific transmission mode of the N physical shared channels to be repeatedly transmitted may be determined according to a preset time domain restriction rule, so as to ensure that the time domain span of the repeatedly transmitted physical shared channels is not too long.

For PDSCH/PUSCH transmission at symbol level or non-slot level, in repeated transmission, if a symbol different from the current transmission channel is encountered, such as a DL symbol encountered on a physical uplink shared channel, or a Flexible (Flexible) symbol is changed to a symbol different from the current transmission channel, a collision of transmission directions will be caused, however, there is no specific scheme for how to solve the transmission collision at present.

In actual transmission, for PDSCH/PUSCH transmission at a symbol level or a non-slot level (that is, a physical shared channel is scheduled based on a non-slot), a situation may be encountered in which a symbol type in a certain slot is changed (for example, a transmission direction of a flexible symbol is adjusted, or a scheduling manner of the flexible symbol is changed, for example, a semi-static flexible symbol is changed into a dynamically scheduled flexible symbol), so that resources originally allocated in the adjusted slot cannot transmit the physical shared channel, thereby causing a collision in the transmission direction.

In the embodiment of the present invention, for the terminal, it does not expect that the dynamic scheduling on the network side will cause such a collision, so for the network side, it can avoid the symbols pre-allocated to the physical shared channel during the dynamic scheduling. Or the terminal may defer transmission of the colliding symbols until the continuously available resources are able to carry the transmission.

However, when the configuration authorized transmission causes the above conflict, the following method may be adopted in the embodiment of the present invention to resolve the transmission conflict:

1. cancelling transmission of physical shared channel resources of symbols colliding located on the slot, or

2. And delaying the rest physical shared channels to the next symbol sequence meeting the condition for transmission.

The above-described situation will typically occur in time slots where there is slot format change signalling. If there is scheduling information or data arriving only after the current timeslot receives the timeslot format change signaling, the sending end may determine transmission resources according to the signaling indication, so from the transmission perspective, in a specific embodiment of the present invention, the repeatedly transmitting N physical shared channels may be described by dividing into multiple segments of transmissions, which specifically includes:

the first M physical shared channels of the N physical shared channels are repeatedly transmitted in the first time slot, where M is a positive integer smaller than N, and in the time domain, transmission resources of any one physical shared channel of the M physical shared channels are continuously distributed in the time domain, that is, the M physical shared channels repeatedly transmitted in the first time slot satisfy a preset transmission rule, so that the problem of collision of transmission directions during repeated transmission in the time slot can be effectively avoided.

Under the condition that the symbol type in the fifth transmission resource is changed, the physical shared channel to be transmitted can be selected to be discarded, or a sixth transmission resource located behind the fifth transmission resource is used for transmitting the physical shared channel to be transmitted; wherein the fifth transmission resource is: in a second time slot after the first time slot, allocating, in advance, continuous transmission resources of the physical shared channel to be transmitted, where the sixth transmission resource is: and in the time domain, the transmission resources are continuously distributed in one time slot.

For example, the transmission resource allocation situation of 4 PUSCH for Physical Uplink Shared Channel (PUSCH) to be repeatedly transmitted in the first slot and the second slot is shown in fig. 4, where symbols 8 to 13 in the first slot (slot n) of the first PUSCH, the second PUSCH and the third PUSCH are allocated in advance,

symbols

2 and 3 in the second slot (slot n +1) of the fourth PUSCH are allocated in sequence, and if the symbol 2 in the second slot (slot n +1) is changed from an F symbol to a D symbol in transmission, the first 3 PUSCHs in the 4 PUSCHs may be repeatedly transmitted in the first slot (slot n), and the fourth PUSCH to be transmitted in the second slot (slot n +1) is discarded, or the fourth PUSCH is delayed to be transmitted to the

symbols

3 and 4 in the second slot (slot n + 1).

In this way, if the symbol type is changed in the subsequent time slot during the repeated transmission, the physical shared channel to be transmitted may be discarded according to the above description in this embodiment, or the physical shared channel to be transmitted may be delayed until the transmission resource continuously distributed in one time slot is transmitted, so that the collision in the transmission direction may be effectively solved.

It should be noted that, during the process of performing repeated transmission, the sending end device and the receiving end device may also pre-configure a Redundancy Version (RV) corresponding to each transmitted physical shared channel.

Specifically, the configuration of the redundancy version can be implemented in different ways, which is described in detail below.

In one mode, the RV version may be indicated by combining a high-layer configuration and a Downlink Control Information (DCI) indication, and a mode in which the RV is configured in advance by a high layer may be used, for example, the configuration mode 1 is: {0,2,3,1}, mode 2 {0,0,0,0}, mode 3 {0,3,0,3}, and after the higher layer indicates the use of one or more of them, the DCI is used to indicate the mode used for the terminal transmission.

For example, if the higher layer indicates to use RV versions of these 3 modes, signaling as shown in table 1 below may be designed in DCI to indicate RV versions used in repeated transmission, where different DCI signaling indicates different transmission modes.

Thus, the terminal can determine the RV version used in each repeated transmission according to the received DCI signaling, and when receiving the DCI signaling of "00", can determine to transmit RV0 for the first transmission, RV2 for the second transmission, RV3 for the third transmission, and RV1 for the fourth transmission.

Table 1 DCI signaling indicates transmission versions

Alternatively, a fixed RV pattern may be used, and only DCI may be used to indicate the RV version used in the repeated transmission, for example, signaling as shown in table 2 below may be designed in DCI to indicate the RV version used in the repeated transmission. In this way, the RV sequence used in each repetition transmission can be determined using only DCI indication without using RCC signaling, and thus transmission overhead can be reduced.

Table 2 DCI signaling indicates transmission versions

If the transmission times are more than or less than the RV version indicated by the DCI, the terminal may determine the RV sequence for transmission in a repeated or truncated manner, that is, the terminal may determine the RV sequence used for each repeated transmission according to the fixed RV pattern and the transmission times. For example, if the DCI indicates that "00" in table 2 is used as the RV sequence used in the repeated transmission, when the DCI indicates that the number of repeated transmissions is 8, it may be determined that the RV versions used in each of the 8 transmissions are 0,2,3,1, 0,2,3, and 1 in a repeated manner, and when the DCI indicates that the number of repeated transmissions is 3, it may be determined that the RV versions used in each of the 3 transmissions are 0,2, and 3 in a truncated manner.

In the embodiment of the present invention, the terminal may be any device having a storage medium, for example: terminal devices such as computers (Computer), Mobile phones, Tablet Personal computers (Tablet Personal Computer), laptop computers (laptop Computer), Personal Digital Assistants (PDA), Mobile Internet Devices (MID), and Wearable devices (Wearable Device).

In the transmission method in this embodiment, when the sending end device performs repeated transmission of the physical shared channel with the receiving end device, the transmission may be performed according to a rule that the transmission resource of any one physical shared channel satisfies continuous distribution in the time domain and is located in the same time slot, so that a mapping position from each physical shared channel of the repeated transmission to the transmission resource may be determined.

Referring to fig. 5, fig. 5 is a flowchart of another transmission method provided in an embodiment of the present invention, where the transmission method is used for a receiving end device, where the receiving end device is a network side device or a terminal, and as shown in fig. 5, the method includes the following steps:

step 501, receiving N physical shared channels which are repeatedly transmitted; n is an integer greater than 1;

It should be noted that, this embodiment is used as an implementation of the receiving end device corresponding to the embodiment shown in fig. 1, and specific implementation thereof may refer to relevant descriptions in the embodiment shown in fig. 1, and for avoiding repeated descriptions, this embodiment is not described again.

Optionally, when the receiving end device is a network side device, before receiving the N physical shared channels of the repeated transmission, the method further includes:

sending repeat transmission indication information, wherein the repeat transmission indication information comprises: the time domain starting position S, the length L of the physical shared channel, and the N are used for the terminal to determine the transmission resources of the N physical shared channels in the time domain by combining the time slot format indication information.
