Description

Resource indication method, equipment and computer readable storage medium

Technical Field

The present application relates to the field of communications, and more particularly, to a method, apparatus, and computer-readable storage medium for resource indication.

Background

In a wireless communication system, when a terminal device needs to send a data channel to a network device, the network device may allocate and schedule a resource for the terminal device, and the terminal device may perform transmission of the data channel on the resource. The resource allocated by the network device to the terminal device may include a time domain resource and/or a frequency domain resource.

Take the time domain resource of uplink transmission scheduled by the network device as the terminal device as an example. The network device may schedule the time domain resource for the terminal device in a scheduling manner based on the time slot, that is, the network device may send scheduling information once in one time slot. The scheduling information includes an indication of the time domain resource allocated to the terminal device by the network device, that is, the scheduling information indicates a starting resource block and a resource length of the time domain resource scheduled and allocated to the terminal device by the network device in one time slot.

Currently, when data is transmitted in a resource unit, the length of a resource block used for data transmission is greater than the maximum value of the resource length. To support more flexible data transmission, data may be transmitted within multiple resource units. In the existing technical solution, a network device indicates a resource scheduled in each resource unit to a terminal device through a plurality of indication information. However, the multiple resource indication values indicate that the large signaling overhead and the large transmission delay caused by resource scheduling in multiple units are problems that need to be solved at present.

In a first aspect, a communication method is provided, including: a first communication device receives first information sent by a second communication device, wherein the first information indicates a first resource indicating value, the first resource indicating value is used for the first communication device to determine a starting resource S and a resource length L, Lmin is less than or equal to Lmax, Lmin is used for representing the minimum value of L, Lmax is used for representing the maximum value of L, range information of the resource length is determined, or a first threshold value is determined, and the starting resource S and the resource length L which are allocated to the first communication device by the second communication device are determined according to the first resource indicating value and the range information of the resource length or the first resource indicating value and the first threshold value, Lmin is less than or equal to (S + L) and less than or equal to Lmax; and the first communication device transmits data by using the starting resource S and the resource length L.

In the embodiment of the present application, the first communication device may be understood as a terminal device, and the second communication device may be understood as a network device.

In the above technical solution, the first network device may determine, by using one resource indication value, that the resource length is greater than the number of symbols included in one time domain unit or the number of resources included in one frequency domain unit, so that it may be avoided that, in the prior art, the first communication device determines resources in multiple units by receiving multiple resource indication values sent by the second communication device, and therefore, a larger resource length may be supported with lower signaling overhead. Meanwhile, the length of the resource indicated by one resource indicated value is larger than the number of symbols included in one time domain unit or the number of resources included in one frequency domain unit, and the transmission delay caused by the fact that a plurality of resource indicated values indicate the resources in a plurality of units can be reduced.

In a possible implementation manner, the first communication device receives second information sent by the second communication device, where the second information indicates range information of the resource length; or the first communication device determines the range information of the resource length according to the received first resource indication value.

The following describes in detail communication between a network device and a terminal device based on the wireless communication system shown in fig. 1. In a wireless communication system, when a terminal device needs to send a data channel to a network device, the network device may allocate and schedule resources for the terminal device, and the terminal device may perform data transmission on the allocated resources. The resource allocated by the network device to the terminal device may include a time domain resource and/or a frequency domain resource.

Take time domain resources of a Physical Uplink Shared Channel (PUSCH) scheduled and transmitted by a network device as a terminal device as an example. In the NR communication system, the network device may schedule time domain resources for the terminal device in a scheduling manner based on a time slot, that is, the network device transmits scheduling information once in one time slot. The scheduling information includes an indication of the time domain resource allocated to the terminal device by the network device, that is, the scheduling information indicates a start symbol and a symbol number (which may also be referred to as a resource length) of the time domain resource allocated to the terminal device by the network device in one time slot. The terminal device may determine the time domain resource allocated by the network device according to the starting symbol (symbol) and the resource length (length) of the time domain resource indicated in the scheduling information, and perform PUSCH transmission on the time domain resource.

For convenience of description, S will be referred to as a starting symbol of PUSCH transmission, and L is referred to as a symbol length of PUSCH transmission.

The number of symbols included in one slot (time slot) is 14 for a normal cyclic prefix (normal CP), and 12 for an extended cyclic prefix (extended CP). With reference to fig. 2 and table 1, the combination between the start symbol of the time domain resource and the resource length scheduled and allocated by the network device for the terminal device is described in detail below by taking a normal cyclic prefix as an example.

Table 1 shows the combination between the starting symbol and the resource length of the time domain resource under the normal CP

Initial symbol (symbol, S)	Resource length (length, L)
		0	1，2，3，4，···，14
1	1，2，3，4，···，13
		2	1，2，3，4，···，12
···	···
		13	1

As shown in fig. 2, slot 1 includes 14 symbols therein. As can be seen from table 1, the value of the starting symbol of PUSCH transmission is {0, 1, 2, ·, 13}, and the value of the resource length is {1, 2, ·, 14 }. Since 14 symbols are included in one time slot, the scheduling information sent by the network device to the terminal device indicates the starting symbol and the resource length of the time domain resource that can be used by the terminal device in one time slot, and therefore 0< S + L is less than or equal to 14.

The network device may indicate a resource indication value to the terminal device when allocating the time domain resource. In NR systems, for example, the resource indication value may be referred to as a Start and Length Indicator Value (SLIV). The SLIV is used to instruct the terminal device to determine the starting symbol and resource length of the PUSCH transmission. The SLIV and the starting symbol (S) and the resource length (L) satisfy the relationship described in the following formula (1) -formula (1-1).

Formula (1):

if (L-1) is less than or equal to 7, SLIV is 14 x (L-1) + S

Formula (1-1):

when 7 < (L-1), SLIV ═ 14 × (14-L +1) + (14-1-S)

Specifically, one possible implementation of the association relationship between the SLIV and the start symbol (S) and the resource length (L) described in the above equation (1) is shown in table 2.

Table 2 shows the association between SLIV of time domain resources and the starting symbol (S), symbol length (L) under normal CP

Specifically, the network device may determine the SLIV according to the association relationship among the starting symbol (S), the resource length (L), and the SLIV described in table 2 according to the combination of the starting symbol (S) and the resource length (L) of the time domain resource scheduled for the terminal device, and send the SLIV to the terminal device. The terminal device determines the starting symbol (S) and the resource length (L) of the time domain resource indicated by the network device according to the SLIV indicated in the scheduling information and the correlation among the starting symbol (S), the resource length (L), and the SLIV as described in formula (1), and performs PUSCH transmission by using the starting symbol (S) and the resource length (L).

It should be understood that, as can be seen from table 2, there are 105 combinations of starting symbols and resource lengths, and the SLIV has a value of (0-104).

What the network device described above indicates in sending scheduling information to the terminal device is a starting symbol S and a resource length L for transmitting PUSCH in one slot. Since the maximum resource length that can be supported by the terminal device for PUSCH transmission in one slot is 14 symbols for the normal CP and 12 symbols for the extended CP, transmission of the PUSCH cannot cross the slot boundary, that is, the terminal device can transmit the PUSCH only at the symbol length included in one slot.

In the prior art, in a plurality of time slots, a network device needs to schedule and indicate a starting symbol for transmitting the PUSCH and a resource length in each time slot. Thus, the multiple SLIVs indicate the time domain resources in the multiple slots, which may cause a large signaling overhead on one hand, and may also cause a large transmission delay on the other hand.

Therefore, in order to better support the low-latency and high-reliability service transmission requirement, the transmission of the PUSCH can be allowed to support a longer symbol length. For example, in fig. 3, each of slot 1 and slot 2 includes 14 symbols, the transmission of PUSCH may cross the boundary between slot 1 and slot 2, and the maximum supported transmission symbol length is 28. In the scenario shown in fig. 3, the network device may instruct the terminal device to transmit the PUSCH starting symbol S and the resource length L in multiple slots through one SLIV, so as to avoid that, in the prior art, for multiple slots, the network device may notify multiple SLIVs of large signaling overhead and large transmission delay caused by the multiple SLIVs. However, since the maximum value of the resource length L indicated by the existing SLIV is the number of symbols (for example, 14 symbols) included in one slot, how the network device indicates that the resource length L is greater than the number of symbols included in one slot through one SLIV becomes a problem that needs to be solved at present.

In the method for indicating resources provided in the embodiment of the present application, the network device may indicate, by using a resource indication value, that the resource length is greater than the number of symbols included in a time domain unit or the resource length included in a frequency domain unit, so as to avoid a large signaling overhead and a large transmission delay caused by a plurality of resource indication values indicating scheduling resources of a plurality of units.

The following describes in detail a resource indication method provided in an embodiment of the present application with reference to an application scenario of fig. 1. Fig. 4 is a schematic flowchart of a resource indication method provided in an embodiment of the present application, where the method shown in fig. 4 includes steps 410 and 430, and the steps 410 and 430 are described in detail below.

Step 410: the second communication device indicates the first resource indication value to the first communication device.

In this embodiment, the first communication device may be a terminal device, and the second communication device may be a network device. For convenience of description, the following description will be given taking the first communication device as a terminal device and the second communication device as a network device as an example.

In the embodiment of the present application, a network device may schedule and allocate resources for a terminal device, and may indicate, by using a resource indication value, an allocated starting resource and a resource length for the terminal device.

As mentioned above, it should be understood that in the time domain resource, the resource may be understood as a symbol, the starting resource indicated by the network device for the terminal device is a starting symbol in the time slot, and the resource length is a symbol length in the time slot (also referred to as resource length S). In the frequency domain resource, the resource may be understood as a resource block, the starting resource indicated by the network device for the terminal device is a starting resource block, and the resource length is a resource block length.

In this embodiment, the network device may indicate the first resource indication value to the terminal device through the first information, where the first information may be carried on control information, such as Downlink Control Information (DCI), or may also be carried on Radio Resource Control (RRC) signaling, and this application is not limited in this respect.

Step 420: the first communication device determines range information or a first threshold value of the length of the resource.

The scope information of the resource length in the embodiment of the present application may be understood as a specific scope of the resource length, or may also be understood as a scope index of the resource length.

There are various specific implementation manners of determining the range information of the resource length by the terminal device, and this is not specifically limited in this embodiment of the application. As an example, the terminal device may receive the second information sent by the network device, where the second information may directly indicate the range information of the resource length, or the second information directly indicates the range index of the resource length. As another example, the terminal device may further determine range information of the resource length according to the received first resource indication value. As another example, the terminal device may further determine range information of the resource length according to the first threshold. The following will be described in detail with reference to specific implementations, which are not described herein again.

It should be understood that, in this embodiment of the present application, the second information may be carried on DCI, or may also be carried on RRC signaling, which is not specifically limited in this application.

In the embodiment of the present application, there are various implementation manners for determining the first threshold by the terminal device, and this is not specifically limited in the present application. As an example, the terminal device may receive third information sent by the network device, and the third information may directly indicate the size of the first threshold. As another example, the terminal device may further determine the size of the first threshold according to the received first resource indication value. The following description will be made in conjunction with specific formulas, which are not repeated herein.

It should be understood that the third information may be carried on the control information. For example, the third information is carried on DCI or RRC signaling, which is not specifically limited in this application.

Step 430: and the first communication equipment determines the starting resource S and the resource length L according to the first resource indication value, the range information of the resource length and/or the first threshold value, and transmits data.

In the embodiment of the application, the terminal device may determine the initial resource and the resource length corresponding to the first resource indication value indicated by the network device according to the range information of the resource length and the association relationship between the first resource indication value and the initial resource and the resource length. The terminal device may further determine, according to the first threshold and the association relationship between the first resource indication value and the initial resource and the length of the resource, the initial resource and the length of the resource corresponding to the first resource indication value indicated by the network device. The following will be described in detail with reference to specific implementations, which are not described herein again.

In the embodiment of the present application, the network device may indicate, by using one resource indication value, that the resource length is greater than the number of symbols included in one time domain unit or the resource length included in one frequency domain unit, so that the signaling overhead and the transmission delay may be smaller.

After determining the starting resource and the resource length indicated by the network device by the terminal device through the method, the terminal device may transmit data by using the starting resource and the resource length. For convenience of description, the following description takes resources allocated by the network device as the terminal device as time domain resources, and takes the first resource indication value as SLIV as an example.

It is mentioned above that the terminal device may determine the range information of the resource length L according to the second information sent by the network device, and the specific second information may indicate the range information of the resource length L by 1 bit or 2 bits.

As an example, the network device indicates the range information of the resource length L through one field in the second information or a plurality of states of the second information. In the case where there are a plurality of pieces of range information, each of a plurality of states of the information may indicate one piece of range information of the resource length L.

As another example, the network device indicates the range information of the resource length L of the allocated time domain resource to the terminal device through bit (bit) signaling in the second information. The network device may indicate one range information of the resource length L by one bit, or may also indicate a plurality of range information of the resource length L by a plurality of bits.

For example, the network device indicates a specific range of one resource length L by one bit in the second information. The specific correspondence is shown in table 3 below.

Table 3 shows the correspondence between the bit and the range of the resource length L

State of bit	Range of L
		0	0<L≤14
1	14<L≤A ₁

Referring to table 3, the network device may indicate a specific range of one L by one bit in the second information transmitted to the terminal device. In the case where the state of the bit is 0, the range that can be used to indicate L is 0<L ≦ 14 (in the case where the number of symbols included in one slot is 7, the maximum value of L is 7, and so on). In the case where the state of the bit is 1, the range that can be used to indicate L is 14<L≤A ₁ Wherein A is ₁ Is a positive integer greater than 14.

It is understood that A ₁ The value of (a) may be predefined, or may also be obtained by the terminal device according to the configuration of the network device. A. the ₁ The value of (2) is related to the number of the time slot boundary spanned by the time domain resource used for transmitting the PUSCH and configured to the terminal equipment by the network equipment. As an example, the time domain resource used by the network device to transmit PUSCH configured for the terminal device may span two slots, a ₁ Is compared with the number of symbols included in the time slot, e.g., the number of symbols included in each of the two time slots is 14, then a ₁ Is 28.

Note that, when the state of the bit is 0, the range indicating L may be 14<L≤A ₁ A bit state of 0 indicates that the range of L is 0<L is less than or equal to 14, which is not done in the examples of the present applicationAnd (4) specifically limiting. For details, refer to the above description, and are not repeated herein.

As another example, the network device indicates the plurality of ranges of the resource length L by two bits in the second information. The specific correspondence is shown in table 4 below.

Table 4 shows the correspondence between the bit and the range of the resource length L

As one example, in the case where 2 bits indicate 3 (S + L) ranges, when the state of a bit is 00, the range that can be used to indicate (S + L) is 0<(S + L) is less than or equal to 14. When the state of the bit is 01, the range that can be used to indicate (S + L) is 14<(S+L)≤A ₁ Wherein A is ₁ Is a positive integer greater than 14. When the state of the bit is 10, the range that can be used to indicate (S + L) is A ₁ <(S+L)≤A ₂ Wherein A is ₂ Is greater than A ₁ Is a positive integer of (1).

Referring to table 4A, the network device may indicate a range of 4 (S + L) by 2 bits in the second information. Further, it is different from table 4 in that when the state of the bit is 11, the indication of the (S + L) range may not be made, or the reserved state may be made.

Table 4A shows the correspondence between the bit and the range of (S + L)

It is understood that A ₂ May be predefined or may be derived by the terminal device according to the configuration of the network device. A. the ₂ The value of (2) is related to the number of the time slot boundary spanned by the time domain resource used for transmitting the PUSCH and configured to the terminal equipment by the network equipment. As an example, the time domain resource used by the network device to transmit PUSCH configured to the terminal device may span three slots, a ₂ And the number of symbols included in the time slot, e.g.The number of symbols included in each of the three slots is 14, then a ₂ Is 42.

As an example, in the case that 2 bits indicate the range of 4L, similar to the above case, specific please refer to the above description, which is not described herein again. In particular, when the state of the bit is 11, the range that can be used to indicate L is A ₂ <L≤A ₃ Wherein A is ₃ Is greater than A ₂ Is a positive integer of (1).

In addition, A is ₃ May be predefined or may be derived by the terminal device according to the configuration of the network device. A. the ₃ The value of (a) is related to the number of time slot boundaries spanned by the time domain resource used by the network device for transmitting the PUSCH configured to the terminal device, and particularly, A ₃ Is 56.

Optionally, in some embodiments, the network device may further indicate the range information of (S + L) and the range information of the resource length L to the terminal device through the second information. Specifically, the range information of (S + L) and the range information of the resource length L may be indicated by a field in the second information or multiple states of the information, or the range information of (S + L) and the range information of the resource length L may be indicated to the terminal device by bit (bit) signaling in the second information. For details, please refer to the above description about the range of the indication L, which is not repeated herein.

For example, the network device indicates both the range of (S + L) and the range of L by one bit. The specific correspondence is shown in table 5 below.

Table 5 shows the correspondence between the bit and the range of resource lengths L, (S + L)

State of bit	(S+L)Range of (1)	Range of L
			0	0<L≤14	0<L≤14
1	14<L≤B ₁	0<L≤14

Referring to table 5, when the state of a bit is 0, the range that can be used to indicate L is 0<L is less than or equal to 14, and the range of (S + L) is 0<L is less than or equal to 14. When the state of the bit is 1, it can be used to indicate that the range of L is 0<L is less than or equal to 14, and the range of (S + L) is 14<L≤B ₁ 。

It is understood that B ₁ May be predefined or may be derived by the terminal device according to the configuration of the network device. B is ₁ In relation to the maximum value of S + L, in particular, B ₁ Is 27 or 28.

As another example, the network device indicates (S + L) and the plurality of ranges of L by two bits in the second information. The specific correspondence is shown in tables 6 to 8 below.

Table 6 shows the correspondence between the bit and the range of resource lengths L, (S + L)

State of bit	(S + L) range	Range of L
			00	0<(S+L)≤14	0<L≤14
01	14<(S+L)≤B ₁	0<L≤14
			10	B ₂ <(S+L)≤B ₃	14<L≤C ₁

Referring to table 6, the network device may indicate the ranges of L and S + L by 2 bits in the information. When the state of the bit is 00, the range that can be used to indicate L is 0<L is less than or equal to 14, and the range of (S + L) is 0<L is less than or equal to 14. When the state of the bit is 01, it can be used to indicate that the range of L is 0<L is less than or equal to 14, and the range of (S + L) is 14<L≤B ₁ . When the state of the bit is 10, it can be used to indicate that the range of L is 14<L≤C ₁ The range of (S + L) is B ₂ <L≤B ₃ 。

It is understood that B ₂ ，B ₃ ，C ₁ May be predefined or may be derived by the terminal device according to the configuration of the network device. In particular, B ₁ Has a value of 28, B ₂ Has a value of 14, B ₃ Has a value of 28, C ₁ Is 28.

There are various specific implementation manners for the terminal device to determine the starting symbol S and the resource length L according to the range information of the resource length L and the SLIV, and detailed description will be given below in conjunction with the specific implementation manners.

Optionally, in some embodiments, the network device may determine the starting symbol S allocated to the terminal device and the SLIV corresponding to the transmission length L' according to an association relationship satisfying the following formula (2). And the terminal device also determines a starting symbol S and a transmission length L corresponding to the SLIV indicated by the network device according to the association relationship described by the following formula (2) -formula (2-1), and performs PUSCH transmission according to the starting symbol S and the transmission length L.

Formula (2):

SLIV is 14 x (L '-1) + S when L' -1 is not more than 7

Formula (2-1):

(L '-1) > 7 then SLIV ═ 14 × (14-L' +1) + (14-1-S)

In one possible implementation, L ═ L' + K, where L is the transmission length that the network device allocates to the terminal device for actually transmitting the PUSCH.

Wherein the parameter K may be indicated by the network device or may also be a maximum value according to L (e.g., L) _max ) Determined, or a predetermined integer.

For example, for 0< L ≦ 14, K ≦ 0. For example, for 14< L ≦ 28, K ≦ 14. For example, for 28< L ≦ 42, K ≦ 28.

As an example, the value of the parameter K is determined according to equation (3).

K＝(ceil(L _max /14)-1)×14 (3)

In the above formula (3), ceil is used to represent a function rounded up.

Taking normal CP as an example, at L _max Is 14 (0)<L is less than or equal to 14)In the formula (2), K is (ceil (14/14) -1) × 14 is 0, and L is L'. At L _max Is 28 (14)<L ≦ 28), K ═ (ceil (28/14) -1) × 14 ═ 14, and L ═ L' +14 in formula (2) above.

It should be noted that, if for the extended CP, L is in one slot _max Is 12, in two time slots L _max Is 24.

For example, when 0< number of resource blocks < ═ 14, L ═ L'. For another example, when 14< number of resource blocks < ═ 28, L ═ L' + M, where M is a preset positive integer. Specifically, the network device may determine the start symbol S allocated to the terminal device and the SLIV corresponding to the transmission length L' according to the association relationship satisfying the following description. And the terminal device also determines a starting symbol S and a transmission length L corresponding to the SLIV indicated by the network device according to the association relationship described below, and performs PUSCH transmission according to the starting symbol S and the transmission length L.

When (L '-1) is less than or equal to 7, SLIV is 14 x (L' -1) + S; or

When (L '-1) > 7, SLIV ═ 14 × (14-L' +1) + (14-1-S).

As an example, M is 14 above.

In another possible implementation, L ═ L' + f (n1), where n1 is the range index associated with resource length L, or a value determined from the range of resource lengths L, or n1 is a value determined from the SLIV. f (n1) is a function of n 1. In the following, taking two time slots as an example, the resource length L included in each time slot is 14, and the association relationship between the range index n1 and the range of the transmission length L is described in detail.

In the present application, the index associated with the range of the resource length L means that the index is related to the range of the transmission length L, or the index is related to the range of (S + L), or the index is related to both the range of the transmission length L and the range of (S + L). For example, possible association relationships between the index associated with the range of the resource length L and the range of the transmission length L and the range of (S + L) are shown in tables 11 and 12.

Table 11 shows an association relationship between an index associated with a range of the resource length L and a range of the transmission length L and (S + L)

Table 12 shows another association relationship between an index associated with a range of the resource length L and a range of the transmission length L and (S + L)

Taking n1 as an example of a value determined from the SLIV, n1 and the SLIV satisfy the relationship described by the following formula (4) -formula (4-1).

Formula (4):

n1＝ceil(SLIV/H)

formula (4-1):

n1＝floor(SLIV/H)

where floor is a rounded down function, H may correspond to the first threshold above. For example, the first threshold is H. Alternatively, the first threshold value may be determined by the association described by the following formula (5) or formula (6).

Formula (5):

first threshold value ceil (SLIV/H) × H

Formula (6):

first threshold value (n1+1) × H

For example, when 0< L ≦ 14 and 0< (S + L) ≦ 14, the maximum value of SLIV within one slot is 104, and the first threshold ceil (SLIV/H) × H is 105, the terminal device may determine n1 according to the first threshold.

The value of H may be predetermined, and in particular, H is 105 or H is 104.

Taking n1 as an example of the index determination associated according to the range of the resource length L, the association relationship described by the following formula (7) -formula (7-1) is satisfied between n1 and the index of the range of the resource length L.

Formula (7):

n1 ceil (index associated with range of resource length L/2)

Formula (7-1):

n1 floor (index associated with range of resource length L/2)

Specifically, according to table 11, the values of n1 are shown in table 13 below.

Table 13 shows an association relationship between indexes associated with ranges of resource lengths L and n1 and n2

There are various specific expressions of f (n1) in the embodiment of the present application, and this embodiment of the present application is not particularly limited to this. Please refer to the relationship described in equation (8) -equation (8-3).

Formula (8):

f(n1)＝14×(n1–J1)

formula (8-1):

f(n1)＝14×floor(n1/2)

equation (8-2):

f(n1)＝14×ceil(n1/2)

equation (8-3):

f(n1)＝7×n1

here J1 is an integer. For example, J1 is a predetermined positive integer.

For example, n1 is 2, f (n1) is 7 × n1 is 14, or f (n1) is 14 × ceil (n1/2) is 14, or f (n1) is 14 × floor (n1/2) is 14, or J1 is 1, f (n1) is 14 × (n 1-J1) is 14, and L in the above formula (2) is L' + 14.

For example, n1 is 1, f (n1) is 14 × ceil (n1/2) is 14, or J1 is 0, f (n1) is 14 × (n 1-J1) is 14, and L is L' +14 in formula (2).

The following describes in detail a specific implementation process of determining, by the terminal device, the start symbol S and the resource length L indicated by the network device, by taking the normal CP as an example and combining two specific embodiments. It should be noted that this example is only for assisting the skilled person in understanding the embodiments of the present application, and is not intended to limit the embodiments of the present application to the specific values or specific scenarios illustrated. It will be apparent to those skilled in the art from the examples given that various equivalent modifications or variations are possible, and such modifications or variations are intended to fall within the scope of the embodiments of the present application.

As an example, L _min ＝1，L _max ＝14，0<S + L is less than or equal to 14. The range of the resource length L allocated to the terminal equipment by the network equipment for transmitting the PUSCH is 0<L is less than or equal to 14 and is 0<S + L is less than or equal to 14. The network device may be according to 0<And L is less than or equal to 14, selecting the association relation among the SLIV, the starting symbol S and the resource length L described in the formula (1) to the formula (1-1) to determine the SLIV, and sending the SLIV to the terminal equipment. Terminal equipment is according to 0<And L is less than or equal to 14, determining the SLIV by selecting the association relationship among the SLIV, the starting symbol S and the resource length L described in the formula (1) and the formula (1-1) and determining the starting symbol S and the resource length L by the SLIV indicated by the network equipment, and transmitting the PUSCH by adopting the starting symbol S and the resource length L.

It should be noted that, in the case that 0< L ≦ 14 and 0< S + L ≦ 14, the network device and the terminal device may further use the association relationship between the SLIV, the start symbol S, and the resource length L described in formula (2) -formula (2-1) provided in this embodiment of the present application.

For example, the starting symbol S of the transmission PUCSH allocated to the terminal device at the network device is 4, the resource length L is 5, and the range of the resource length L is 0< L ≦ 14. The network device may determine that the corresponding SLIV is 60 when the start symbol S is 4 and the resource length L is 5 according to the association relationship between the start symbol S, the resource length L, and the SLIV in equation (1). The network device may indicate SLIV 60 to the terminal device via the first information and 0< L ≦ 14 via the second information. The terminal device determines that when the SLIV is 60, the starting symbol S is 4 and the resource length L is 5 according to 0< L ≦ 14 and the association relationship between the starting symbol S, the resource length L', and the SLIV in formula (1). The terminal equipment adopts the starting symbol S-4 and the resource length L-5 to transmit PUSCH.

As another example, L _min ＝14，L _max ＝28，14<S + L is less than or equal to 28. The range of the resource length L allocated to the terminal equipment by the network equipment for PUSCH transmission is 14<L.ltoreq.28, and 14<S + L is less than or equal to 28. The network device may select the association relationship described in the above equation (2) -equation (2-1) to determine the SLIV, and send the SLIV to the terminal device. After the terminal device receives the SLIV indicated by the network device, the resource length L 'and the starting symbol S' corresponding to the SLIV are determined according to the association described by the formula (2) -formula (2-1). The terminal equipment can also be 14 according to the range of the resource length L<L ≦ 28, and K ═ 14 in equation (2) or f (n1) ═ 14 in equation (8) are determined. The terminal device may determine the starting symbol S and the resource length L for transmission of the PUSCH from L ═ L' + 14.

For example, the network device schedules the terminal device with the resource length L of the time domain resource being 16 and the starting symbol S being 2. The network device may first determine that L ═ L-14 ═ 16-14 ═ 2 according to the range of the resource length L of the terminal device for transmitting PUSCH is 14< L ≦ 28, select the association relationship between the SLIV and L', S described in the above equation (2) to determine that SLIV ≦ 16, and may indicate that SLIV ≦ 16 to the terminal device through the first information and indicate that 14< L ≦ 28 through the second information. The terminal device determines, according to the association relationship described by 14< L ≦ 28 and equation (2), that when the SLIV is 16, the resource length L ═ L' +14 ═ 2+14 ═ 16 and the starting symbol S ═ 2 corresponding to the SLIV are determined, and performs PUSCH transmission using the resource length L ═ 16 and the starting symbol S ═ 2.

In the above technical solution, the network device indicates the range information of L and/or (S + L) to the terminal device through the indication information, so that the existing calculation formula of the SLIV can be reused, and thus, in a scenario where a boundary across a time domain is indicated by one SLIV, the complexity of implementation of the terminal device and the network device is reduced.

Optionally, in some embodiments, the network device may determine the start symbol S allocated to the terminal device and the SLIV corresponding to the transmission length L according to an association relationship satisfying the following formula (9) -formula (9-1). And the terminal device also determines a start symbol S and a transmission length L corresponding to the SLIV indicated by the network device according to the association relationship described by the following formula (9) -formula (9-1), and performs PUSCH transmission by using the start symbol S and the transmission length L.

Formula (9):

(L- (f (n1) +1)) ≦ 7, SLIV ═ 14 × (L- (f (n1) +1)) + S + f (n2)

Formula (9-1):

(L- (f (n1) +1)) > 7, SLIV ═ 14 × ((f (n1) +14) -L +1) + (14-1-S) + f (n2)

Where n2 is an index associated with a range of resource lengths, or n2 is a value determined from the range of resource lengths, or n2 is a value determined from the first resource indication value. for a detailed description of f (n1), reference is made to the above description, and details are not repeated herein, where f (n2) is a function related to n2, and f (n1) is a function related to n 1.

Taking n2 as an example of a value determined according to the SLIV, n2 and the SLIV satisfy the relationship described by the following equation (10) -equation (10-1).

Equation (10):

n2＝ceil(SLIV/H)

formula (11):

n2＝floor(SLIV/H)

taking n2 as an example, which is a value determined according to the range of the resource length L, the association relationship described by the following equation (11) -equation (11-1) is satisfied between n2 and the range index of the resource length L.

Formula (11):

n2 ceil (index associated with range of resource length L/2)

Formula (11-1):

n2 floor (index/2 associated with the range of resource lengths L);

there are various specific expressions of f (n2) in the embodiment of the present application, and this is not particularly limited in the embodiment of the present application. Please refer to the relationship described in equation (12).

Formula (12):

f(n2)＝H×(n2–J2)

the calculation of n1, n2, f (n2) is as described above and will not be described herein.

Taking the normal CP as an example, a specific implementation process of determining, by the terminal device, the start symbol S and the resource length L indicated by the network device through the above formula (9) -formula (9-1) is described in detail below with reference to two specific embodiments. It should be noted that this example is only for assisting the skilled person in understanding the embodiments of the present application, and is not intended to limit the embodiments of the present application to the specific values or specific scenarios illustrated. It will be apparent to those skilled in the art from the examples given that various equivalent modifications or variations are possible, and such modifications or variations also fall within the scope of the embodiments of the application.

As an example, the resource length L allocated by the network device to the terminal device for PUSCH transmission ranges from 0< L ≦ 14, and 0< S + L ≦ 14. The network device can select the association relation among the SLIV, the starting symbol S and the resource length L in the formula (1) to the formula (1-1) to determine the SLIV according to the condition that L is more than 0 and less than or equal to 14, and send the SLIV to the terminal device. And the terminal equipment determines and selects the association relation among the SLIV, the starting symbol S and the resource length L described in the formula (1) to the formula (1-1) according to the condition that the L is less than or equal to 14, determines the SLIV and determines the starting symbol S and the resource length L according to the SLIV indicated by the network equipment, and transmits the PUSCH by adopting the starting symbol S and the resource length L.

It should be noted that, in the case that 0< L ≦ 14 and 0< S + L ≦ 14, the network device and the terminal device may also use the association relationship between the SLIV, the start symbol S, and the resource length L described in formula (9) -formula (9-1) provided in the embodiments of the present application.

For example, the starting symbol S of the transmission PUCSH allocated to the terminal device at the network device is 4, the resource length L is 5, and 0< L ≦ 14. The network device may determine that the corresponding SLIV is 60 when the start symbol S is 4 and the resource length L is 5 according to the association relationship between the start symbol S, the resource length L, and the SLIV in equation (9). The network device may indicate to the terminal device that SLIV is 60 through the first information and that 0< L ≦ 14 through the second information. The terminal device determines f (n1) ═ 0 and f (n2) ═ 0 in equation (9) according to 0< L ≦ 14, determines start symbol S ═ 4 and resource length L ═ 5 according to SLIV ═ 60 and the association between start symbol S, resource length L and SLIV described in equation (9), and performs PUSCH transmission using start symbol S ═ 4 and resource length L ═ 5.

As another example, the resource length L allocated to the terminal device for PUSCH transmission at the network device is in the range of 14< L ≦ 28, and 14< S + L ≦ 28. The network device may select the association described in equation (9) above to determine the SLIV, and send the SLIV and 14< L ≦ 28 to the terminal device. The terminal device determines that n1 is 0 and n2 is 1 in formula (9) according to 14< L ≦ 28. The terminal device may determine the starting symbol S and the resource length L according to the association described by the SLIV and equation (9), and perform PUSCH transmission by using the starting symbol S and the resource length L.

For example, the resource length L of the time domain resource scheduled by the network device for the terminal device is 16, and the start symbol S is 2. The network device determines that f (n1) ═ 14 and f (n2) ═ H ═ 105 in formula (9-1) according to the resource length L range of 14< L ≦ 28, determines that the resource length L ═ 16 and the SLIV ═ 121 corresponding to the starting symbol S ≦ 2 according to the association described in formula (9-1), and transmits the SLIV ≦ 121 and 14< L ≦ 28 to the terminal device. The terminal device determines that f (n1) ═ 14 and f (n2) ═ H ═ 105 in formula (9-1) according to the range of resource length L of 14< L ≦ 28. The terminal device may determine, according to the association relationship described by SLIV 121 and equation (9-1), a start symbol S-2 and a resource length L-16, and perform PUSCH transmission using the start symbol S-2 and the resource length L-16.

Optionally, in some embodiments, the network device may determine the starting symbol S allocated to the terminal device and the SLIV corresponding to the transmission length L according to an association relationship satisfying the following formula (13) -formula (13-1). And the terminal device also determines a starting symbol S and a transmission length L corresponding to the SLIV indicated by the network device according to an association relationship described in the following formula (13) -formula (13-1), and performs PUSCH transmission by using the starting symbol S and the transmission length L.

Formula (13):

(L- (f (n1) +1)) ≦ 7, SLIV × (L- (f (n1) +1)) + S × (14 ×))

Formula (13-1):

(L- (f (n1) +1)) > 7, SLIV ═ 14 × ((f (n1) +14) -L +1) + (14-1-S)

The calculation of n1, f (n1) is as described above and will not be described here.

The following describes in detail a specific implementation process of determining, by the terminal device, the start symbol S and the resource length L indicated by the network device through the above formula (13) -formula (13-1), by taking the normal CP as an example, and combining two specific embodiments. It should be noted that this example is only for assisting the person skilled in the art in understanding the embodiments of the present application, and is not intended to limit the embodiments of the present application to the specific values or specific scenarios illustrated. It will be apparent to those skilled in the art from the examples given that various equivalent modifications or variations are possible, and such modifications or variations also fall within the scope of the embodiments of the application.

For example, the starting symbol S of the transmission PUCSH allocated to the terminal device at the network device is 4, the resource length L is 5, and 0< L ≦ 14. The network device may determine that the corresponding SLIV is 60 when the start symbol S is 4 and the resource length L is 5 according to the association relationship between the start symbol S, the resource length L, and the SLIV in equation (13). The network device may indicate to the terminal device that SLIV 60 through the first information and that 0< L ≦ 14 through the second information. The terminal device determines f (n1) in formula (13) to be 0 according to 0< L ≦ 14, determines the starting symbol S to be 4 and the resource length L to be 5 according to the SLIV 60 and the association relationship among the starting symbol S, the resource length L, and the SLIV described in formula (13), and performs PUSCH transmission using the starting symbol S to be 4 and the resource length L to be 5.

As another example, the resource length L allocated to the terminal device for PUSCH transmission at the network device is in the range of 14< L ≦ 28, and 14< S + L ≦ 28. The network device may select the association described in the above formula (13) to determine the SLIV, and send the SLIV and 14< L ≦ 28 to the terminal device. The terminal device determines that n1 in formula (13) is 0 according to 14< L ≦ 28. The terminal device may determine the starting symbol S and the resource length L according to the association described by the SLIV and equation (13), and perform PUSCH transmission by using the starting symbol S and the resource length L.

For example, the resource length L of the time domain resource scheduled by the network device for the terminal device is 16, and the start symbol S is 2. The network device determines that f (n1) in the formula (13-1) is 14 according to the resource length L range of 14< L ≦ 28, determines that the resource length L is 16 and the SLIV corresponding to the starting symbol S of 2 is 121 according to the association described in the formula (13-1), and transmits the SLIV 121 and 14< L ≦ 28 to the terminal device. The terminal device determines f (n1) ═ 14 in equation (13-1) according to the range of resource length L being 14< L ≦ 28. The terminal device may determine the starting symbol S ═ 2 and the resource length L ═ 16 according to the association relationship described by SLIV ═ 121 and equation (13-1), and perform PUSCH transmission using the starting symbol S ═ 2 and the resource length L ═ 16.

Optionally, in some embodiments, the network device may determine the start symbol S allocated to the terminal device and the SLIV corresponding to the transmission length L according to an association relationship satisfying the following formula (14) -formula (14-1). And the terminal device also determines a starting symbol S and a transmission length L corresponding to the SLIV indicated by the network device according to an association relationship described in the following formula (14) -formula (14-1), and performs PUSCH transmission by using the starting symbol S and the transmission length L.

Formula (14):

when L1< resource length L is less than or equal to L2 and L1< (S + L) is less than or equal to L2,

(L- (L1+ 1)). ltoreq.7 SLIV ═ 14 × (L- (L1+1)) + S

Formula (14-1):

(L- (L1+1)) > 7, SLIV ═ 14 × (L2-L +1) + (14-1-S)

It is understood that L1 can be a positive integer greater than 13 and L2 a positive integer greater than L1. Specifically, L2 is 14+ L1.

In one possible implementation, when 0< resource length L ≦ 14, L1 ≦ 0 and L2 ≦ 14.

In another possible implementation, when 14< resource length L ≦ 28, L1 ≦ 14, and L2 ≦ 28.

The following describes in detail a specific implementation process of determining, by the terminal device, the start symbol S and the resource length L indicated by the network device through the above formula (13) -formula (13-1), by taking the normal CP as an example, and combining two specific embodiments. It should be noted that this example is only for assisting the skilled person in understanding the embodiments of the present application, and is not intended to limit the embodiments of the present application to the specific values or specific scenarios illustrated. It will be apparent to those skilled in the art from the examples given that various equivalent modifications or variations are possible, and such modifications or variations also fall within the scope of the embodiments of the application.

As an example, the resource length L allocated by the network device to the terminal device for PUSCH transmission ranges from 0< L ≦ 14, and 0< S + L ≦ 14. The network device may select the association relationship between the SLIV, the starting symbol S, and the resource length L in the above formula (14) -formula (14-1) to determine the SLIV according to 0< L ≦ 14, and send the SLIV to the terminal device. And the terminal equipment determines and selects the association relation among the SLIV, the starting symbol S and the resource length L described in the formula (14) -formula (14-1) according to the condition that L is less than or equal to 0, determines the SLIV and determines the starting symbol S and the resource length L according to the SLIV indicated by the network equipment, and transmits the PUSCH by adopting the starting symbol S and the resource length L.

It should be noted that, in the case that 0< L ≦ 14 and 0< S + L ≦ 14, the network device and the terminal device may further use the association relationship between the SLIV, the start symbol S, and the resource length L described in formula (1) -formula (1-1) provided in this embodiment of the present application.

For example, the starting symbol S of the transmission PUCSH allocated to the terminal device at the network device is 4, the resource length L is 5, and 0< L ≦ 14. The network device may determine that the corresponding SLIV is 60 when the start symbol S is 4 and the resource length L is 5 according to the association relationship between the start symbol S, the resource length L, and the SLIV in equation (14-1). The network device may indicate to the terminal device that SLIV is 60 through the first information and that 0< L ≦ 14 through the second information. The terminal device determines that L1 is 0 and L2 is 14 in equation (14) according to 0< L ≦ 14, determines that the start symbol S is 4 and the resource length L is 5 according to SLIV 60 and the association relationship between the start symbol S, the resource length L, and the SLIV described in equation (14-1), and performs PUSCH transmission using the start symbol S is 4 and the resource length L is 5.

As another example, the resource length L allocated to the terminal device for PUSCH transmission at the network device is in the range of 14< L ≦ 28, and 14< S + L ≦ 28. The network device may select the association described in equation (14) above to determine the SLIV, and send the SLIV and 14< L ≦ 28 to the terminal device. The terminal device determines that L1 is 14 and L2 is 28 in formula (13) according to 14< L ≦ 28. The terminal device may determine the starting symbol S and the resource length L according to the association described by the SLIV and equation (14), and perform PUSCH transmission by using the starting symbol S and the resource length L.

For example, the resource length L of the time domain resource scheduled by the network device for the terminal device is 16, and the start symbol S is 2. The network device determines that L1 is 14 and L2 is 28 in formula (14-1) according to the range of resource length L is 14< L ≦ 28, determines that the resource length L is 16 and SLIV 121 corresponding to the start symbol S is 2 according to the association described in formula (14-1), and transmits SLIV 121 and 14< L ≦ 28 to the terminal device. The terminal device determines that L1-14 and L2-28 in the formula (14-1) according to the range of the resource length L of 14< L ≦ 28. The terminal device may determine the starting symbol S ═ 2 and the resource length L ═ 16 according to the association described by the SLIV ═ 121 and the formula (14-1), and perform PUSCH transmission using the starting symbol S ═ 2 and the resource length L ═ 16.
