S201: The terminal device receives the indication information sent by the network device, where the indication information is used to instruct the terminal device to determine the first resource pattern from the first candidate set.

The first candidate set includes at least one resource pattern, and the resource pattern in the first candidate set corresponds to a first subcarrier spacing.

It should be understood that, in the embodiment of the present invention, one candidate set corresponds to one subcarrier spacing, that is, all resource patterns in one candidate set correspond to the same seed carrier interval. For example, if the subcarrier spacing corresponding to the first candidate set is 15 kHz, then all resource patterns in the first candidate set are determined according to the subcarrier spacing of 15 kHz.

It should be understood that a candidate set may correspond to a resource allocation in a bandwidth, or may be allocated to a resource in a plurality of bandwidths, which is not limited by the present invention.

Optionally, the resource allocation in a candidate set is in an interlace, and the frequency domain distance between two adjacent RBs in the RB included in one comb tooth is the same, wherein the adjacent two RBs are the same The frequency domain distance between the two includes the distance between the starting subcarrier of the previous RB and the starting subcarrier of the latter RB. Taking the resource allocation unit in the first candidate set as the first comb, for example, assuming that the first candidate set is a resource allocation corresponding to the first bandwidth, and according to the first subcarrier interval, the first bandwidth includes N1 first RBGs ( RB Group, resource block group), and each of the first RBGs includes M1 resource blocks RB with continuous frequency domain resources, N1 and M1 are natural numbers, and N1>=2, M1>=2. A first comb includes one of the first RBGs of the N1 first RBGs, and the RBs included in the first comb include the same position in each of the first RBGs.

By way of example and not limitation, the first subcarrier spacing is 60 kHz, and the first bandwidth illustrates the first comb based on the example that the 60 kHz subcarrier spacing may include 25 RBs (RB numbers 0 to 24). As shown in the first case of FIG. 3, the first bandwidth includes five first RBGs, and each of the first RBGs includes five consecutive RBs of frequency domain resources, and one first comb includes each of the five first RBGs. One RB in the first RBG, and the frequency domain distance between two adjacent RBs in the RB included in the first comb includes the same. That is, the first bandwidth includes five first combs, and the numbers are 0 to 4. wherein the first comb having the label 0 includes the labels of the RBs of 0, 5, 10, 15, and 20; The comb includes RBs labeled 1, 6, 11, 16, 21; the first comb labeled 2 includes RBs labeled 2, 7, 12, 17, 22; the first comb labeled 3 The RBs included are numbered 3, 8, 13, 18, 23; the first combs numbered 4 include RBs numbered 4, 9, 14, 19, 24. The resource pattern in the first candidate set may include one or more first combs. For example, the resource pattern in a first candidate set includes a first comb labeled 0. As another example, the resource pattern in another first candidate set includes first combs labeled 3 and 4.

By way of example and not limitation, the first sub-carrier spacing is 30 kHz, and the first bandwidth is illustrated by taking 50 RBs (RB numbers 0 to 49) as an example. As shown in case 2 of FIG. 3, the first bandwidth includes five first RBGs, and each of the first RBGs includes ten consecutive RBs of frequency domain resources, and one first comb includes each of the five first RBGs. One RB in the first RBG, and the frequency domain distance between two adjacent RBs in the RB included in the first comb includes the same. That is, the first bandwidth includes 10 first combs, and the numbers are 0 to 9, wherein the first comb having the label 0 includes the labels of the RBs of 0, 10, 20, 30, 40; The comb includes RBs numbered 1, 11, 21, 31, 41; and so on. The resource pattern in the first candidate set may include one or more first combs. For example, the resource pattern in a first candidate set includes a first comb labeled 0. As another example, the resource pattern in another first candidate set includes first combs labeled 0, 2, 4, 6, 8.

By way of example and not limitation, the first sub-carrier spacing is 15 kHz, and the first bandwidth is illustrated by taking the example of the 15 kHz sub-carrier spacing, which may include 100 RBs (RB numbers 0 to 99). As shown in case 3 of FIG. 3, the first bandwidth includes five first RBGs, and each of the first RBGs includes 20 consecutive RBs of frequency domain resources, and one first comb includes each of the five first RBGs. One RB in the first RBG, and the frequency domain distance between two adjacent RBs in the RB included in the first comb includes the same. That is, the first bandwidth includes 20 first combs, and the numbers are 0 to 19, wherein the first comb having the label 0 includes the labels of the RBs of 0, 20, 40, 60, 80; the first number is 1. The combs include RBs numbered 1, 21, 41, 61, 81; and so on. The resource pattern in the first candidate set may include one or more first combs. For example, the resource pattern in a first candidate set includes a first comb labeled 0. As another example, the resource pattern in another first candidate set includes first combs labeled 0, 5, 10, 15.

Optionally, if the first bandwidth includes the N1 first RBGs, and the RBs that do not belong to the N1 first RBGs, the frequency domain distance between the adjacent two RBs in the RBs that satisfy one comb includes the same The first comb tooth may further include an RB that does not belong to the N1 first RBGs. By way of example and not limitation, the first subcarrier spacing is 60 kHz, the first bandwidth may include 27 RBs according to the 60 kHz subcarrier spacing (RB numbers are 0 to 26), and the RBs including 5 frequency domain resources in the first RBG are consecutive. As an example, the first comb teeth in this case will be described. As shown in case 4 of FIG. 3, the first bandwidth includes five first combs, numbered from 0 to 4, wherein the first comb including the number 0 includes RBs having labels of 0, 5, 10, 15, and 20 25; the first comb tooth numbered 1 includes RBs numbered 1, 6, 11, 16, 21, 26; the first comb tooth numbered 2 includes RBs numbered 2, 7, 12, 17 22; the first comb tooth numbered 3 includes RBs numbered 3, 8, 13, 18, 23; the first comb tooth numbered 4 includes

RB numbers

4, 9, 14, 19, 24 .

It should be understood that there may be one or more subcarrier spacings in the communication system. Correspondingly, when performing resource allocation, the network device may perform resource allocation on the terminal device according to the resource pattern in one or more candidate sets.

For example, the network system may perform resource allocation on the terminal device according to the resource pattern in the two candidate sets, where the resource pattern in the first candidate set corresponds to the first subcarrier spacing, and the resource pattern in the second candidate set. Corresponding to the second subcarrier spacing, by allocating resource patterns in different candidate sets, terminal devices that use different subcarrier spacing for signal transmission can be multiplexed on the same time domain resource.

S202: The terminal device determines the first resource pattern from the first candidate set according to the indication information.

In a possible implementation, the determining, by the terminal device, the first resource pattern from the first candidate set according to the indication information, including:

Determining, by the terminal device, the second resource pattern from the second candidate set according to the indication information, where the second candidate set includes at least one resource pattern, and the resource pattern in the second candidate set corresponds to the second subcarrier interval;

The terminal device determines the first resource pattern from the first candidate set according to the second resource pattern and the first subcarrier spacing.

Optionally, when the network system needs to perform resource allocation on the terminal device according to the resource pattern corresponding to the at least two subcarrier spacings, in order to reduce signaling indication overhead, a resource pattern corresponding to one subcarrier spacing may be used as a basic pattern, The resource corresponding to another seed carrier interval is allocated.

Without prior loss, the resource pattern in the second candidate set corresponding to the second subcarrier spacing is used as a basic pattern, and resource allocation is performed on resources corresponding to the first subcarrier spacing (ie, the resource pattern is selected from the first candidate set) For example, an embodiment of the present invention will be described.

Optionally, a frequency domain distance between adjacent frequency RBs of one of the first combs in the first candidate set and a neighboring RB of a second comb of the second candidate set The same, wherein the frequency domain distance between two adjacent RBs includes: a distance between a starting subcarrier of a previous RB and a starting subcarrier of a subsequent RB. As an example and not limitation, as shown in FIG. 3, it is assumed that the subcarrier spacing corresponding to the first candidate set is 60 kHz, and the subcarrier spacing corresponding to the second candidate set is 30 kHz, and the frequency between adjacent RBs in the first comb. The domain interval is 5 RBs with subcarrier spacing of 60 kHz, that is, 5*12*60 kHz=3600 kHz. The frequency domain interval between adjacent RBs in a second comb is 10 RBs with subcarrier spacing of 30 kHz, that is, 10*12. *30 kHz = 3600 kHz, therefore, the frequency domain distance between adjacent RBs in one first comb is the same as the frequency domain distance between adjacent RBs in a second comb.

Optionally, the indication information indicates resource allocation in the first candidate set by indicating a resource pattern in the second candidate set. For example, the second candidate set includes N resource allocation modes, and the indication information indicates one or more corresponding resource patterns in the N resource allocation manners, and the resource pattern and the first subcarrier interval indicated by the indication information correspond to The first comb and the relationship between the first resource pattern and the frequency domain resources occupied by the second resource pattern are used to determine a resource pattern corresponding to the first subcarrier spacing.

Optionally, the first resource pattern and the second resource pattern occupy the same frequency domain resource, where the first subcarrier spacing and the second subcarrier spacing are different.

Optionally, the first subcarrier spacing is greater than the second subcarrier spacing, and the frequency domain resource occupied by the first resource pattern includes a frequency domain resource occupied by the second resource pattern.

Optionally, the first subcarrier spacing is smaller than the second subcarrier spacing, and the frequency domain resource occupied by the first resource pattern is a subset of the frequency domain resources occupied by the second resource pattern.

Optionally, the first subcarrier spacing is smaller than the second subcarrier spacing, and the indication information is further used to indicate a location of the frequency domain resource occupied by the first resource pattern in the frequency domain resource occupied by the second resource pattern.

In the following, the subcarrier spacing in case 1 of FIG. 3 is 60 kHz, the first bandwidth includes 25 RBs, and the 25 RBs are divided into five comb comb structures as the resource pattern unit in the second candidate set. (In other words, the second subcarrier spacing is 60 kHz), an embodiment of the present invention will be described. Referring to FIG. 4, the second candidate set includes five second comb teeth, and the five second comb teeth are sequentially numbered #0 to #4. That is, the resource allocation in the system is allocated by #0 to #4. Specifically, if the second resource pattern includes one second comb tooth, the second resource pattern may be comb tooth #0, or comb tooth #1, or comb tooth #2, or comb tooth #3, or comb tooth# 4; if the second resource pattern includes 2 second comb teeth, the second resource pattern may be comb teeth #0 and #1, or comb teeth #1 and #2, or comb teeth #2 and #3, or comb Teeth #3 and #4, or comb teeth #0 and #2, and so on, and so on.

If the first subcarrier spacing and the second subcarrier spacing are the same, for example, the first subcarrier spacing is also 60 kHz, the resource pattern corresponding to the allocated second comb is the first resource pattern for uplink information transmission. As shown in FIG. 4, the assigned second comb is labeled #0, and the first comb corresponding to the first resource pattern for uplink information transmission is also labeled #0.

If the first subcarrier spacing and the second subcarrier spacing are different, for example, the first subcarrier spacing is 30 kHz or 15 kHz, the first resource pattern and the second resource pattern may also occupy the same frequency domain resource. As shown in FIG. 4, assuming that the first subcarrier spacing is 30 kHz and the assigned second comb tooth is #2, the first resource pattern and the second resource pattern occupy the same frequency domain resource, that is, used for uplink information transmission. The first comb teeth corresponding to the first resource pattern are numbered #4 and #5. Assuming that the first subcarrier spacing is 15 kHz and the assigned second comb tooth is #4, the first resource pattern and the second resource pattern occupy the same frequency domain resource, that is, the first resource pattern corresponding to the uplink information transmission. The first comb teeth are numbered #16, #17, #18, and #19.

If the first subcarrier spacing is smaller than the second subcarrier spacing, the frequency domain resource occupied by the first resource pattern may also be a subset of the frequency domain resources occupied by the second resource pattern. Also taking FIG. 4 as an example, assuming that the first subcarrier spacing is 30 kHz, the assigned second comb tooth is #2, and the second combo pattern corresponding to the first comb tooth is #4 and #5, then The first comb tooth corresponding to the first resource pattern of the uplink information transmission has the label #4; or the first comb tooth corresponding to the first resource pattern for the uplink information transmission has the label #5. Further, the indication information is further used to indicate the location of the frequency domain resource occupied by the first resource pattern in the frequency domain resource occupied by the second resource pattern, for example, the indication information is used to indicate that the first resource pattern corresponding to the uplink information transmission corresponds to The number of the first comb is #4 or #5.

In the following, the subcarrier spacing in Case 2 of FIG. 3 is 30 kHz, the first bandwidth includes 50 RBs, and the 50 RBs are divided into 10 comb comb structures as the resource pattern unit in the second candidate set.

Referring to FIG. 5, the second candidate set includes 10 second comb teeth, and the 10 second comb teeth are sequentially numbered #0 to #9. That is, the resource allocation in the system is allocated by #0 to #9. Specifically, if the second resource pattern includes one second comb tooth, the second resource pattern may be comb tooth #0, or comb tooth #1, or comb tooth #2, or comb tooth #3, etc.; The second resource pattern includes 2 second comb teeth, then the second resource pattern may be comb teeth #0 and #1, or comb teeth #1 and #2, or comb teeth #2 and #3, or comb teeth #3 And #4, or comb teeth #0 and #2, and so on, and so on.

If the first subcarrier spacing and the second subcarrier spacing are the same, for example, the first subcarrier spacing is also 30 kHz, the resource pattern corresponding to the allocated second comb is the first resource pattern for uplink information transmission. As shown in FIG. 5, the assigned second comb is labeled #4, and the first comb corresponding to the first resource pattern for uplink information transmission is also labeled #4.

That is, as long as the second resource pattern includes at least one of the second combs of the label #0 or #1, the first comb pattern includes the first comb tooth numbered #0.

In the following, the subcarrier spacing in Case 3 of FIG. 3 is 15 kHz, the first bandwidth includes 100 RBs, and the 100 RBs are divided into 20 comb comb structures as the resource pattern unit in the second candidate set.

Specifically, if the second resource pattern includes one second comb tooth, the second resource pattern may be comb tooth #0, or comb tooth #1, or comb tooth #2, or comb tooth #3, etc.; The second resource pattern includes 2 second comb teeth, then the second resource pattern may be comb teeth #0 and #1, or comb teeth #1 and #2, or comb teeth #2 and #3, or comb teeth #3 And #4, or comb teeth #0 and #5, and so on, and so on.

If the first subcarrier spacing and the second subcarrier spacing are the same, for example, the first subcarrier spacing is also 15 kHz, the resource pattern corresponding to the allocated second comb is the first resource pattern for uplink information transmission. As shown in FIG. 6, the assigned second comb has the number #16, and the first comb corresponding to the first resource pattern for the uplink information transmission has the label #16.

If the first subcarrier spacing is greater than the second subcarrier spacing, for example, the first subcarrier spacing is 60 kHz or 30 kHz, the frequency domain resources occupied by the first resource pattern include frequency domain resources occupied by the second resource pattern. As shown in FIG. 6, it is assumed that the first subcarrier spacing is 60 kHz, the assigned second comb tooth is #0, and the resource pattern corresponding to the second comb tooth labeled #0 is the first comb labeled #0. A part of the resource pattern corresponding to the tooth, the first comb tooth corresponding to the first resource pattern for uplink information transmission is labeled #0. In other words, the resource pattern corresponding to the first comb tooth labeled #0 is the same as the resource pattern corresponding to the second comb tooth labeled #0, #1, #2, #3, as long as the second resource pattern includes the label At least one of the second comb teeth of #0, #1, #2, #3 includes the first comb tooth numbered #0 in the first resource pattern.

Similarly, as shown in FIG. 6, it is assumed that the first subcarrier spacing is 30 kHz, the assigned second comb tooth is #8, and the resource pattern corresponding to the second comb tooth numbered #8 is the first number labeled #4. A part of the resource pattern corresponding to the comb, the first comb tooth corresponding to the first resource pattern for uplink information transmission is labeled #4. In other words, since the resource pattern corresponding to the first comb having the number #4 is the same as the resource pattern corresponding to the second comb labeled #8 and #9, the second resource pattern includes the labels #8 and #9. At least one of the second comb teeth includes a first comb tooth numbered #4 in the first resource pattern.
