The method and the device realize that a flexible silencing mechanism is added in the process of sending the SRS by the terminal so as to avoid the problems that the number of terminals supporting the uplink is limited due to the limitation of uplink positioning to resources, the relevant problems of reference signal conflict are not solved well, and flexibly solve the problem that the terminal cannot be identified due to the consistent sequence caused by the consistent configured time-frequency resources under the condition that the signals of the SRS are the same but the terminals are different.

As an optional embodiment, the muting indication includes a resource unit bitmap, where the resource unit bitmap includes N bits, and each bit indicates whether a resource unit is muted, where the granularity of the resource unit is greater than or equal to 1.

Specifically, the resource unit includes at least one of: the device comprises a reference signal resource unit, a reference signal resource set unit, a time domain symbol unit of a reference signal, a physical resource block unit of a candidate resource in a frequency domain, a frequency hopping unit of the reference signal and a port unit of the candidate resource.

The silence indication is detailed below for different resource units:

A) reference signal resource unit bitmap:

the length of the reference signal resource unit bitmap is N1, where:

n1 is equal to the number of resources of the candidate resource, each bit indicating whether the corresponding 1 resource is silent; or,

n1 is equal to the number of resources of the candidate resource divided by the preset resource granularity, each bit indicating whether the corresponding preset resource granularity resource is silent.

In this embodiment, the candidate resource may be a target resource or all resources of the pre-configured SRS, or a resource in one or more resource sets, or one or more resources of the pre-configured SRS, where the target resource is an SRS resource initially determined or configured or defined by the terminal.

When N1 is equal to the number of resources of the candidate resource, and each bit indicates whether the corresponding 1 resource is silent, if the bit is 0, the resource indicated by the bit is silent, and if the bit is 1, the resource indicated by the bit is not silent (normally transmitted); of course, when the bit is 0, the resource indicated by the bit is not muted, and when the bit is 1, the resource indicated by the bit is muted (normally transmitted).

In the case that N1 is equal to the number of resources of the candidate resource divided by the preset resource granularity, each bit indicates whether the corresponding preset resource granularity resources are silent, where the preset resource granularity resources may be a continuous plurality of resources. For example, if the number of resources in the first reference signal resource set is 20 and the preset resource granularity is 5, N1 is 4, and if the bit is 0 indicating no transmission and the bit is 1 indicating normal transmission, the resource unit bitmap "1000" indicates that only the first 5 resources out of the 20 resources transmit SRS. The first 5 resources may be the first 5 resources in any order, e.g., according to configuration priority, list order, transmission priority, etc.

B) Reference signal resource set unit bitmap:

the length of the reference signal resource set unit bitmap is N4, wherein:

n4 is equal to the number of resource sets of the candidate resource set, each bit indicating whether the corresponding 1 resource set is silent; or,

n4 is equal to the number of resource sets of the candidate resource set divided by the preset resource set granularity, each bit indicating whether the corresponding preset resource set granularity resource sets are muted.

C) Time domain symbol unit bitmap of reference signal:

the time domain symbol unit bitmap of the reference signal has a length N2, wherein,

n2 is equal to the number of symbols in the time domain or slot where the candidate resource is located, each bit indicating whether the corresponding 1 symbol is silent; or,

n2 is equal to the number of symbols in the time domain or slot where the candidate resource is located, divided by the preset symbol granularity, each bit indicating whether the corresponding preset symbol granularity number of symbols is silent.

The first method is as follows: when N2 is equal to the number of symbols in the time domain or time slot where the candidate resource is located, and each bit indicates whether the corresponding 1 symbol is silent, if the bit is 0, the symbol indicated by the bit is silent, and if the bit is 1, the symbol indicated by the bit is not silent (normal transmission); of course, when the bit is 0, the symbol indicated by the bit may be muted, and when the bit is 1, the symbol indicated by the bit may not be muted (normal transmission).

The second method comprises the following steps: n2 is equal to the number of symbols in the time domain or time slot where the candidate resource is located, divided by the preset symbol granularity, where each bit indicates whether the corresponding preset symbol granularity number of symbols is silent, the symbols of the resource may be grouped according to the preset symbol granularity, that is: every preset symbol granularity is one group of symbols, so that one bit indicates one group of symbols, when the bit is 1, the group of time domain symbols indicated by the bit is silent, and when the bit is 0, the group of symbols indicated by the bit is not silent (normally transmitted); or, when the bit is 1, the group of symbols indicated by the bit is not silent (normally transmitted), and when the bit is 0, the group of time domain symbols indicated by the bit is silent.

Taking N ═ comb size as an example, for one resource, repeated symbols may be muted. Such as:

in the case of the comb-2,

when the number of the symbols is 2, the length of the time domain symbol unit bitmap is 1;

when the number of symbols is 4, the length of the time domain symbol unit bitmap is 2;

when the number of the symbols is 8, the length of the time domain symbol unit bitmap is 4;

when the number of symbols is 16, the length of the time domain symbol unit bitmap is 6.

In the case of comb-4, the number of the comb-4,

when the number of the symbols is 4, the length of the time domain symbol unit bitmap is 1;

when the number of the symbols is 8, the length of the time domain symbol unit bitmap is 2;

when the number of symbols is 12, the length of the time domain symbol unit bitmap is 3.

In the case of comb-8,

when the number of symbols is 8, the length of the time domain symbol unit bitmap is 1.

For example, N2 is equal to the other divisor of the number of symbols in the time domain or time slot where the candidate resource is located, e.g., for comb-4, N is 8. Then the bitmap length may be 2. For comb-4, the first 4 symbols or the last 4 symbols may actually be transmitted.

Here, the way that the time domain symbol unit performs muting or non-muting through the resource unit bitmap indication is an implementation way of time domain symbol muting.

D) A physical resource block unit PRB bitmap of a frequency domain where the candidate resources are located:

the PRB bitmap has a length N9, where,

n9 is equal to the number of PRBs in the frequency domain where the candidate resource is located, and each bit indicates whether a corresponding one of the PRBs is silent; or

N9 is equal to the number of PRBs in the frequency domain where the candidate resource is located divided by the preset PRB granularity, and each bit indicates whether the corresponding PRB of the preset PRB granularity is silent.

Here, the pack of the number of PRBs in the frequency domain in which the candidate resource is located may be at least one of the number of PRBs in the frequency domain resource of the one or more reference signal resource sets, the number of PRBs in the frequency domain resource of the one or more reference signal resources, the number of PRBs in the frequency domain resource of the scheduled BWP, and the number of PRBs in the frequency domain resource of the positioning frequency layer.

E) Frequency hopping unit bitmap of reference signal:

the length of the frequency hopping unit bitmap is N10, wherein,

n10 equals the hop count, each bit indicating whether a corresponding one of the hop positions is silent; or

N10 is equal to the hop count divided by the preset hop count granularity, each bit indicating whether the corresponding preset hop count granularity hop positions are silent.

F) Port unit bitmap of candidate resource:

the bit of the port unit bitmap of the candidate resource is used for indicating whether the signal of the corresponding port is silent.

As an optional embodiment, the silence indication includes identification information of resource items, the identification information including:

a reference identity and a target number; or,

identification information of all target objects.

Specifically, the resource items include at least one of: reference signal resources, a reference signal resource set, time domain symbols of the reference signal, physical resource blocks in a frequency domain where the candidate resources are located, frequency hopping of the reference signal, and ports of the candidate resources. Here, the target object may be a silent resource item or a non-silent resource item.

The silence indication is detailed below for different resource items:

A) in case the resource item comprises a reference signal resource:

under the condition that the identification information includes a reference identification and a target number, the target number is the number of continuous silent resources to be indicated by the silent indication, and the reference identification is the identification of a certain resource in the continuous silent resources, so that the terminal silences the target number of resources including the reference resource corresponding to the reference identification according to the silent indication, such as: if the target number is K, the resource for muting may be: the reference identifies the corresponding resource and its preceding consecutive K-1 resources; the reference identifies the corresponding resource and the consecutive K-1 resources thereafter; or the resource corresponding to the reference identifier, the K-M resources before the resource corresponding to the reference identifier, and the M-1 resources after the resource corresponding to the reference resource identifier. Of course, the resources corresponding to the reference identifier and the target number may also be used to indicate the resources that do not perform muting (i.e. the resources that normally transmit). Of course, the identification information may comprise sets of reference identifications and target numbers, i.e. the case where there is no continuity between sets of resources but there is a continuity of resources within each set.

It should be noted that the reference identifier and the number of targets can be encoded by a Resource Indication (RIV) Value, i.e. the reference identifier and the number of targets can be expressed by a function Value of the two, such as the RIV Value. For example, the function value Z + target number may also be indicated directly.

And under the condition that the identification information comprises the identification information of all the target objects, the terminal performs silencing/non-silencing on the target resources corresponding to the identification of the target objects according to the silencing indication.

B) In the case where the resource item comprises a set of reference signal resources:

under the condition that the identification information comprises the reference identification and the target number, the terminal silences the resource sets with the target number including the reference signal resource set corresponding to the reference identification according to the silence indication.

And under the condition that the identification information comprises the identification information of all the target objects, the terminal performs silencing/non-silencing on the target resource set corresponding to the identification of the target object according to the silencing indication.

C) In case the resource item comprises a time domain symbol of a reference signal:

under the condition that the identification information comprises the reference identification and the target number, the terminal silences the time domain symbols of the target number including the reference identification according to the silence indication, and if: if the target number is K, the muted time domain symbols may be: the reference mark corresponds to a symbol and K-1 consecutive symbols before the symbol; the reference mark corresponds to a symbol and K-1 consecutive symbols thereafter; or the symbol corresponding to the reference mark and K-M symbols before the symbol and M-1 symbols after the symbol corresponding to the reference mark. Of course, the symbols corresponding to the reference identifier and the target number can also be used to indicate the symbols not muting (i.e. the symbols normally transmitted). If: the reference signal is discontinuous within a symbol, and the previously continuous time domain symbol is muted, either ignoring or not ignoring symbols of non-reference signals for muting.

It should be noted that the reference mark and the number of targets may be represented by RIV codes or may be directly indicated.

Take comb-6,12 symbols as an example: configuring the starting symbol of silence as the starting symbol in resource, such as (0, 6) (symbol 0 is resource 1 st symbol); the number of symbols is 6, then the first 6 symbols are muted, or the first 6 symbols are transmitted.

And under the condition that the identification information comprises the identification information of all the target objects, the terminal performs silencing or does not perform silencing (normally send) on the target symbols corresponding to the identifications of the target objects according to the silencing indication.

It should be noted that the terminal may perform muting or normal transmission on the target symbol according to preconfigured information, where the preconfigured information includes: and muting the target symbol determined by the reference identifier and the target number in the obtained muting indication or the target symbol corresponding to the identifier of the target object, or not muting (normally sending) the target symbol determined by the reference identifier and the target number in the obtained muting indication or the target symbol corresponding to the identifier of the target object.

D) In case the resource item comprises a physical resource block in the frequency domain of the candidate resource:

in the case where the identification information includes the reference identification and the number of targets, the method includes: referring to a Physical Resource Block (PRB) identifier and the number of PRBs of a first PRB;

when the identification information includes identification information of all target objects, the method includes: all PRB identities of the first PRB.

The first PRB belongs to a PRB in the frequency domain where the candidate resource is located. Here, the pack of the number of PRBs in the frequency domain in which the candidate resource is located may be at least one of the number of PRBs in the frequency domain resource of the one or more reference signal resource sets, the number of PRBs in the frequency domain resource of the one or more reference signal resources, the number of PRBs in the frequency domain resource of the scheduled BWP, and the number of PRBs in the frequency domain resource of the positioning frequency layer.

It should be noted that the first PRB may be a PRB in a candidate resource that needs muting, or may be a PRB in a candidate resource that needs transmitting

E) In the event that the resource item includes a port of a candidate resource:

and under the condition that the identification information comprises the reference identification and the target number, the terminal performs silencing/non-silencing on the signals of the target number of port numbers including the port number corresponding to the reference identification according to the silencing indication.

And under the condition that the identification information comprises the identification information of all target objects, the terminal performs silencing/non-silencing on the signals of the target port numbers corresponding to the identifications of the target objects according to the silencing indication.

As an optional embodiment, in the case that the time-domain muting comprises periodic muting, the muting indication comprises: a first level period bitmap and/or a second level period bitmap.

Optionally, the length of the first-stage period bitmap is equal to a first preset threshold, and each bit indicates whether one or more periods are silent.

In one embodiment, the first preset threshold may be determined according to the number of transmission cycles of the SRS, for example: if the SRS is transmitted in 100 periods, the first preset value may be set as a divisor of 100, for example: 10. 20, 25, 100, and the like, in a case that the first preset threshold is 20, each bit indicates whether 5 periods are silent, where a plurality of periods indicated by each bit may be consecutive periods, and the SRS transmission period may be a period within one large frame, or a period configured by a network.

In another embodiment, the first preset threshold and/or the number of cycles, and/or the relationship to cycles is determined by configuration or predefined.

In yet another embodiment, a first preset threshold of 32 is specified, and the number of cycles in a large frame is 64, then the bitmap is 32, and each bit value indicates the corresponding period silence or transmission in every 32 cycles starting with a certain starting point. In another embodiment, the specified number of cycles is 32, the first preset value is 4, and the period within the large frame is 64, then each bit indicates whether to mute every 32 cycles in a group of 8 cycles.

The network side device may indicate that a bit in the first-stage period bitmap is 1 to represent that one or more periods indicated by the bit are not silent, and a bit in the first-stage period bitmap is 0 to represent that one or more periods indicated by the bit are silent; alternatively, a bit of 1 may indicate that one or more periods indicated by the bit are quiet, and a bit of 0 may indicate that one or more periods indicated by the bit are not quiet.

Optionally, the length of the second-stage period bitmap is equal to a second preset threshold, and each bit indicates whether one or more periods are silent; or,

the second-stage periodic bitmap has a length of N3, N3 is equal to a divisor of the number of periods represented by each bit in the first-stage periodic bitmap, wherein each bit indicates whether R consecutive periods of one or more resources are silent, and the product of R and N3 is equal to the number of periods represented by each bit in the first-stage periodic bitmap; alternatively, each bit indicates whether one or more cycles are silent.

Specifically, for the case where each bit indicates whether or not consecutive R periods of one or more periods are silent: by dividing the periods into N3 groups, each group then includes R periods, and whether to mute according to the first stage period bitmap is indicated by the second stage period bitmap. For example, if "1" represents non-silence, "0" represents silence, 30 cycles, the first preset value is 5, the first-stage cycle bitmap is "10010," "10010" represents that the first group of 6 cycles and the 4 th group of 6 cycles are not silent, the second-stage cycle bitmap is "010," i.e., "010" represents that the second group of cycles in the three groups of cycles sends other silences after dividing (cycles in a group) into 3 groups; that is, only the third and fourth periods in the first and fourth groups grouped according to the first preset value are finally transmitted, that is, the 2 nd, 3 rd, 21 rd and 22 th periods are transmitted. Thus, R2, the product of R and N3 equals 6, 6 30 cycles/preset value

Or in yet another embodiment, the first preset value is 6 in 30 cycles, the first-stage cycle bitmap is "100100", the "100100" indicates that the first group of 5 cycles and the 4 th group of 5 cycles are not silent, the second-stage cycle bitmap is "010", namely, after the (cycles in the group) are divided into 3 groups, "010" indicates that the 6 groups of cycles (all cycles) are divided into 3 groups, "010" indicates that the first, second, fifth and sixth groups of cycles are all silent, and only the third and fourth groups of cycles are sent, that is, only the 11 th to 20 th cycles are sent; or the first-stage period mutting and the second-stage period mutting can be combined, so that only the fourth group of periods, namely 16 th to 20 th periods, need to be sent; embodiments like the above may be extended to period repetition, frequency domain repetition, frequency hopping repetition, etc., to name but a few.

It should be noted that, under the condition that the length of the second-level period bitmap is equal to the first preset threshold (that is, the second preset threshold is equal to the first preset threshold), each bit of the second-level period bitmap is indicated as each bit of the first-level period bitmap in a manner, which is not described herein again, where the mute indication may use one of the first-level period bitmap and the second-level period bitmap.

While the length of the second stage period bitmap may be equal to a divisor of the number of periods represented by each bit in the first stage period bitmap, each bit of the second stage period bitmap indicates whether or not consecutive R repeated resources are muted, the product of R and N3 being equal to a divisor of the period repetition factor.

As shown in FIG. 3, the "SRS-stopping BitRepetitionisFactor" is 4, which means that each bit in the first-stage period bitmap represents four periods.

At this time, the length of the second-stage period bitmap is equal to 2 (i.e., N3 ═ 2), then 2 consecutive period instances (instances) are grouped, and for each group of period instances, the muting/non-muting is performed according to the indication of the second-stage period bitmap. And the second-stage period bitmaps of the multiple groups of period instances are the same. Of course, if the bit of the first stage periodic bitmap is 0, then the silence is also not affected by the second stage periodic bitmap, and in some embodiments, the first and second stage bitmaps are in a logical and or logical or relationship.

For the case where each bit indicates whether one or more cycles are silent: after the repetition times are grouped into a plurality of groups according to N3, N3 periods included in each group are repeated, and whether to transmit according to the first-stage period bitmap is indicated by the second-stage period bitmap, that is, R is 1. For example, if "1" represents no silence, "0" represents silence, 30 cycles, the repetition factor is 6, the first-stage cycle bitmap is "100100", "100100" represents that the first-group cycle and the fourth-group cycle are not silent, the second-stage cycle bitmap is "010", that is, all cycles) after a resource group of 3 cycles, "010" indicates that the first cycle in the cycle of each group is silent, the second cycle is silent according to the first-stage cycle bitmap, and the third cycle is silent, combining the first-stage cycle repetition bitmap only indicates that the first-group and the fourth-group transmit, and 6 cycles are silent. Here, R is 1.

As shown in FIG. 4, the "SRS-stopping BitRepetitionisFactor" is 4, which means that each bit in the first-stage period bitmap represents four periods.

At this time, the second stage period bitmap length is equal to 4 (i.e., N3 ═ 4), then the second stage period bitmap can further mute/unmute the SRS for 4 periods. Of course, if the bit of the first stage periodic bitmap is 0, then the silence is not affected by the second stage bitmap.

In the following, this embodiment is described with another specific example:

it should be noted that, when the bit is 1, the bit indicates that one or more periods are not quiet, and when the bit is 0, the bit indicates that one or more periods are quiet.

Assuming that the SRS transmission period is 100 and the first-stage period bitmap length is 5, each bit in the first-stage period bitmap represents 20 periods, and then the second-stage period bitmap length may be: 1.2, 4, 5, 10, and 20, if the length of the second-stage periodic bitmap is 5, when the first-stage periodic bitmap is 01000, the SRS from the 21 st transmission period to the 40 th transmission period indicated by the second bit in the first-stage periodic bitmap is not muted (normally transmitted); when the second-stage period bitmap is 01010, the first-stage period bitmap indicates that a plurality of periods (from the 21 st transmission period to the 40 th transmission period) which are not silent are executed, and transmission or muting is performed according to the second-stage period bitmap, specifically, under the condition that each bit in the second-stage period bitmap indicates whether continuous R periods of one or more resources are silent, the 25 th transmission period to the 28 th transmission period indicated by the second bit in the second-stage period bitmap are not silent, and the 33 th transmission period to the 36 th transmission period indicated by the fourth bit in the second-stage period bitmap are not silent; under the condition that each bit in the second-stage period bitmap indicates whether one period is repeatedly silenced in the current period, grouping the 21 st transmission period to the 40 th transmission period according to the length of the second-stage period bitmap, namely, grouping every 5 periods, wherein a plurality of periods in each group determine whether the periods are silenced according to the bits of the second group bitmap, and under the condition, the 22 nd, 24 th, 27 th, 29 th, 32 th, 34 th, 37 th and 39 th periods are not silenced.

As an optional embodiment, in the case that the time-domain muting comprises repeated resource muting, the muting indication comprises: the first level resource repeating bitmap and/or the second level resource repeating bitmap.

Optionally, the length of the first-stage resource repetition bitmap is equal to a first repetition factor, and each bit indicates whether resource repetition of one or more resources is silent; or

The first stage resource repetition bitmap has a length of N4, N4 is equal to a divisor of a first repetition factor, and each bit indicates whether or not consecutive M resource repetitions of one or more resources are muted, the product of M and N4 being equal to the first repetition factor.

The first repetition factor is a predefined number of times that the resource to be repeated is repeatedly transmitted. Wherein, the resource to be repeated may be one or more resources, that is: the first repetition factor may be a resource repetition factor.

In the case that the length of the first level resource repetition bitmap is equal to the first repetition factor, such as: "1" represents not quiet, "0" represents quiet, the first repetition factor is 3, and the first level resource repetition bitmap is "010," 010 "represents that the resource of the second repetition of the resource to be repeated is not quiet, and the resource of the first repetition and the third repetition is quiet.

In case the first level resource repetition bitmap has a length of N4, N4 is equal to a divisor of a first repetition factor, and each bit indicates whether or not consecutive M resource repetitions of one or more resources are muted, the product of M and N4 being equal to said first repetition factor, for example: "1" represents no silence, "0" represents silence, the first repetition factor is 20, and the length of the first level resource repetition bitmap can be set to a divisor of 20, such as: 1.2, 4, 5, 10, 20; if the length of the first-stage resource repeating bitmap is 4, each bit of the first-stage resource repeating bitmap indicates whether continuous 5 resource repeating are silent; specifically, if the first-level resource repetition bitmap is "0101", "0101" indicates that the 6th to 10 th and 16 th to 20 th resources of the resource to be repeated are repeated and not muted, and the 1 st to 5 th and 11 th to 15 th resources are repeated and muted, the 5 th resource repetition can be sent for 5 consecutive times of the resource to be repeated.

Optionally, the length of the second-level resource repetition bitmap is a first repetition factor, and each bit indicates whether resource repetition of one or more resources is silent; or

The length of the second level resource repetition bitmap is N5, N5 is equal to a divisor of the first repetition factor, and each bit indicates whether or not consecutive K resource repetitions of one or more resources are muted, the product of K and N5 is equal to the first repetition factor, or each bit indicates whether or not one or more resources are muted at the current resource repetition.

It should be noted that, under the condition that the length of the second-level resource repetition bitmap is equal to the first repetition factor, each bit of the second-level resource repetition bitmap is indicated in a manner of, for example, each bit of the first-level resource repetition bitmap, which is not described herein again, where the mute indication may use one of the first-level resource repetition bitmap and the second-level resource repetition bitmap.

When the length of the second level resource repetition bitmap may be equal to the divisor of the first repetition factor and is not equal to the repetition factor, each bit of the second level resource repetition bitmap indicates whether consecutive K repeated resources are muted, and the product of K and N5 is equal to the divisor of the first repetition factor.

Here, each repeated resource (i.e., sequentially repeated resources) includes all resources, for example, if 30 resources are set as SRS resources, and the first repetition factor is 6, then one repeated resource includes the 30 resources, or may take a form of jointly indicating a resource group according to the first repetition factor, for example, one repeated resource includes one resource group.

Specifically, the following description is made for a case where each bit indicates whether consecutive K resources of one or more resources repeat muting or not: after the resources are repeatedly divided into N5 groups, each group comprises K repeated resources, and whether the bitmap repetition is repeated according to the first-stage resources is indicated through the second-stage resource repetition bitmap. For example, if "1" represents no silence, "0" represents silence, 30 resources, the first repetition factor is 6, the first level resource repetition bitmap is "100100", "100100" represents that the resources of the first repetition and the fourth repetition are not silence, the second level resource repetition bitmap is "010", i.e., after dividing the repetition times (all repeated resources) into 3 groups, "010" represents that all the resources of the first group repetition (i.e., the 1 st repeated resource and the 2 nd repeated resource) are silence; the second group of repeated resources (namely, the 3 rd repeated resource and the 4 th repeated resource) sends the SRS according to the silencing mode of the first-stage resource repeated bitmap, and because the first-stage resource repeated bitmap indicates the 3 rd repeated silencing, and the 4 th repeated non-silencing, the 3 rd repeated resource is silencing and the 4 th repeated resource is non-silencing; the third set of repeated resources (i.e. the 5 th repeated resource and the 6th repeated resource) are all muted. Thus, K equals 2 and the product of K and N5 equals 6.

As shown in fig. 5, each SRS resource in the figure is a repeated resource, and may include one or more resources. If "1" represents no silence, "0" represents silence, 1 SRS resource, and a first repetition factor (SRS-resource repetition factor) is 8, at this time, the first-stage resource repetition bitmap length is equal to 8, the second-stage resource repetition bitmap length N2 takes a divisor of 8, such as N2 is 4, and the repetition times are divided into 4 groups, and in the second-stage resource repetition bitmap, "1" represents that the group repeats transmission according to the first-stage resource repetition bitmap; "0" indicates that the set of repeats is all muted.

For the case where each bit indicates whether one or more resources are muted at the current resource repetition: after the repetition times are divided into a plurality of groups according to N5, N5 resources included in each group are repeated, and whether the transmission is carried out according to the first-stage resource repetition bitmap is indicated through the second-stage resource repetition bitmap, namely K is 1. For example, if "1" represents no silence, "0" represents silence, 30 resources, the first repetition factor is 6, the first-level resource repetition bitmap is "100100", 100100 "represents that the first repeated and fourth repeated resources are not silence, the second-level resource repetition bitmap is" 010 ", that is, after the repetition times (all repeated resources) are grouped by 3 repeated resources," 010 "indicates that the first repeated resource in each group of repeated resources is silence, the second repeated resource is repeated according to the first-level resource repetition bitmap, and the third repeated resource is silence, the first-level resource repetition bitmap is combined to indicate that the first repeated and fourth repeated transmissions are only performed, and the 6 repeated resources are all silence. Here, K is 1.

As shown in fig. 6, if "1" represents no silence, "0" represents silence, 1 SRS resource, and the first repetition factor (SRS-resource repetition factor) is 8, at this time, the first-level resource repetition bitmap length is equal to 8, and the second-level resource repetition bitmap length N2 takes a divisor of 8, such as N2 being 4, and the repetition times are divided into 2 groups every 4 groups, and in the second-level resource repetition bitmap of one group, "1" represents that a certain repeated resource in the group of repetitions is transmitted according to the first-level resource repetition bitmap; "0" represents that the resources of a repetition in the set of repetitions are all muted.

Optionally, for each repeated resource, under the condition that at least one of the first-level resource repetition bitmap and the second-level resource repetition bitmap indicates silence, the repeated resource is silenced.

Specifically, when the repeated resource silence is determined by the first-stage resource repeating bitmap, the repeated resource silence is determined by the second-stage resource repeating bitmap, or the repeated resource silence is determined by the first-stage resource repeating bitmap and the second-stage resource repeating bitmap, the determination may be performed in the manner described above, and details are not repeated here.

In the case that the time-domain muting comprises repeated resource set muting, the muting indication comprises: the first level resource set repeats the bitmap and/or the second level resource set repeats the bitmap.

The length of the first level resource set repetition bitmap is equal to a second repetition factor, and each bit indicates whether resource set repetition of one or more resource sets is silent; or

The first level resource set repetition bitmap has a length of N7, N7 is equal to a divisor of a second repetition factor, and each bit indicates whether consecutive P resource set repetitions of one or more resource sets are muted, the product of P and N7 being equal to the second repetition factor.

Wherein the second repetition factor is the number of times that the predefined set of resources to be repeated is repeatedly transmitted. Wherein, the resource set to be repeated may be one or more resource sets, that is: the second repetition factor may be a resource set repetition factor.

In the case that the length of the first level resource set repetition bitmap is equal to the second repetition factor, such as: "1" represents not quiet, "0" represents quiet, the second repetition factor is 3, and the first level resource set repetition bitmap is "010," and "010" represents that the resource of the second repetition of the resource set to be repeated is not quiet, and the resource set of the first repetition and the third repetition is quiet.

In the case where the first level resource set repetition bitmap is of length N7, N7 equals a divisor of the second repetition factor, and each bit indicates whether consecutive P resource set repetitions of one or more resource sets are muted, the product of P times N7 equals the second repetition factor, e.g.: "1" represents no silence, "0" represents silence, the second repetition factor is 20, and the length of the first level resource set repetition bitmap can be set to a divisor of 20, such as: 1.2, 4, 5, 10, 20; if the first-level resource set repetition bitmap is 4, each bit of the first-level resource set repetition bitmap indicates whether continuous 5 resource set repetitions are silent; specifically, if the first level resource set repetition bitmap is "0101", "0101" indicates that the resource sets repeated 6th to 10 th times and 16 th to 20 th times of the resource sets to be repeated are not silent, and the resource sets repeated 1 st to 5 th times and 11 th to 15 th times are silent.

Optionally, the length of the second level resource set repetition bitmap is a second repetition factor, and each bit indicates whether resource set repetition of one or more resource sets is silent; or

The second level resource set repetition bitmap has a length of N8, N8 is equal to a divisor of a second repetition factor, and each bit indicates whether or not consecutive Q resource set repetitions of one or more resource sets are muted, the product of Q and N8 is equal to the second repetition factor, or each bit indicates whether or not one or more resource sets are muted in a current resource set repetition.

It should be noted that, under the condition that the length of the second level resource set repetition bitmap is equal to the second repetition factor, each bit of the second level resource set repetition bitmap is indicated as a mode of each bit of the first level resource set repetition bitmap, which is not described herein again, and here, the silence indication may use one of the first level resource set repetition bitmap and the second level resource set repetition bitmap.

When the length of the second level resource set repetition bitmap may be equal to a divisor of the second repetition factor and is not equal to the second repetition factor, each bit of the second level resource set repetition bitmap indicates whether or not consecutive Q repeated resource sets are muted, and the product of Q and N8 is equal to the divisor of the second repetition factor.

Here, each repeated resource set (i.e., sequentially repeated resource sets) includes all resource sets, and if 30 resource sets are set as SRS resource sets and the second repetition factor is 6, one repeated resource set includes the 30 resource sets.

Specifically, for the case where each bit indicates whether consecutive Q resource sets of one or more resource sets repeat muting or not: by repeating the resource sets into N8 groups, each group then includes Q repeated resource sets, with the second level resource set repeating bitmap indicating whether the bitmap repeat as per the first level resource set. For example, if "1" represents not silence, "0" represents silence, 30 resource sets, the second repetition factor is 6, the first level resource set repetition bitmap is "100100", "100100" represents that the first repeated and fourth repeated resource sets are not silence, the second level resource set repetition bitmap is "010", i.e., after dividing the number of repetitions (the total repeated resource sets) into 3 groups, "010" represents that the first repeated resource set (i.e., the 1 st repeated resource set and the 2 nd repeated resource set) is all silence; the second group of repeated resource sets (namely, the 3 rd repeated resource set and the 4 th repeated resource set) sends SRS according to the silencing mode of the first-level resource set repeated bitmap, and because the first-level resource set repeated bitmap indicates the 3 rd repeated silencing, and the 4 th repeated non-silencing, the 3 rd repeated resource set is silenced and the 4 th repeated resource set is not silenced; the third set of duplicate resource sets (i.e., the 5 th duplicate resource set and the 6th duplicate resource set) are all muted. Thus, Q is 2 and the product of Q and N8 is equal to 6.

For the case where each bit indicates whether one or more resource sets are muted in the current resource set repetition: after the repetition times are grouped into a plurality of groups according to N8, the N8 resources included in each group are repeated, and whether to transmit the repeated bitmap according to the first-level resource set is indicated by the repeated bitmap of the second-level resource set, namely Q is 1. For example, if "1" represents non-silence, "0" represents silence, 30 resource sets, the second repetition factor is 6, the first level resource set repetition bitmap is "100100", "100100" represents that the first and fourth repeated resource sets are not silence, the second level resource set repetition bitmap is "010", that is, after the repetition times (all repeated resource sets) are grouped by 3 repeated resource sets, "010" indicates silence for each group of repeated resource sets, the first repeated resource set in each group of repeated resource sets, the second repeated resource set is repeated by the first level resource set repetition bitmap, and the third repeated resource set is silence, then combining the first level resource set repetition bitmap only indicates the first and fourth repeated transmissions, and the 6 repeated resources are all silent. Here, Q is 1.

Optionally, for each repeated resource set, under the condition that at least one of the first level resource set repetition bitmap and the second level resource set repetition bitmap indicates silence, the repeated resource set is muted.

Specifically, when the repeated resource set silence is determined by the first-level resource set repeated bitmap, the repeated resource set silence is determined by the second-level resource set repeated bitmap, or the repeated resource set silence is determined by the first-level resource set repeated bitmap and the second-level resource set repeated bitmap, the determination may be performed in the manner described above, and details are not repeated here.

As an alternative embodiment, the first or second repetition factor of the mute indication comprises: an inter-slot repetition factor and/or an intra-slot repetition factor.

Specifically, the inter-slot repetition factor is used to indicate that a resource or a resource set is repeated in different slots, and the intra-slot repetition is used to indicate that a resource or a resource set is repeated in the same slot.

And under the condition that the first repetition factor or the second repetition factor comprises an inter-slot repetition factor and an intra-slot repetition factor, the silence indication comprises two levels of bitmaps for:

indicating both inter-slot repetition and intra-slot repetition; or,

only inter-slot repetition or intra-slot repetition is indicated.

Specifically, the inter-slot repetition and intra-slot repetition are indicated simultaneously as the resource/resource set is repeated both within the slot and between the slots; namely: the resource/resource set is repeatedly transmitted at least twice in each of at least two slots; indicating only the intra-slot repetition as the resource/resource set is repeated only in the same slot; only inter-slot repetition is indicated as the resource/resource set is repeated only between different slots, i.e.: the resource/resource level is transmitted once in each of a plurality of slots. Wherein the resource comprises one or more resources and the set of resources comprises one or more sets of resources.

Of course, similar embodiments as the above repetition of resources/resource sets can also be extended to periodic repetition, frequency domain repetition, frequency hopping repetition, etc., to name a few.

In an embodiment of the present application, frequency domain resources of the candidate resources of the reference signal satisfy at least one of:

frequency domain resources of one or more sets of reference signal resources;

frequency domain resources of one or more reference signal resources;

frequency domain resources of the scheduled bandwidth part BWP;

the frequency domain resources of the frequency layer are located.

As an optional embodiment, in the case that the frequency-domain muting comprises frequency-domain repeated muting, the muting indication comprises: the first-stage frequency domain repetition bitmap and/or the second-stage frequency domain repetition bitmap.

Optionally, the length of the first-stage frequency-domain repetition bitmap is equal to a frequency-domain repetition factor, and each bit indicates whether repetition of one or more PRBs is silent; or

The first stage frequency-domain repetition bitmap has a length of N11, N11 is equal to a divisor of a frequency-domain repetition factor, and each bit indicates whether X consecutive repetitions of one or more PRBs are muted, the product of X and N11 being equal to the frequency-domain repetition factor.

In the case that the length of the first-stage frequency-domain repetition bitmap is equal to the frequency-domain repetition factor, such as: "1" represents non-silence, "0" represents silence, the frequency-domain repetition factor is 4, the first-level frequency-domain repetition bitmap is "0010," and "0010" represents that one or more PRBs of the third time frequency-domain repetition are not silent, and one or more PRBs of the first, second, and fourth time frequency-domain repetitions are silent.

In case the first stage frequency-domain repetition bitmap has a length of N11, N11 is equal to a divisor of a frequency-domain repetition factor, and each bit indicates whether X consecutive repetitions of one or more PRBs are silent, the product of X and N11 being equal to said frequency-domain repetition factor, for example: "1" represents no silence, "0" represents silence with a frequency-domain repetition factor of 20, and the length of the first-stage frequency-domain repetition bitmap may be set to a divisor of 20, such as: 1.2, 4, 5, 10, 20; if the first-stage frequency domain repetition bitmap is 4, each bit of the first-stage frequency domain repetition bitmap indicates whether 5 repetitions are silent; specifically, if the first-level frequency domain repetition bitmap is "0101", "0101" indicates that 6th to 10 th and 16 th to 20 th repeated PRBs are not muted, and 1 st to 5 th and 11 th to 15 th repeated PRBs are muted.

Optionally, the length of the second-stage frequency-domain repetition bitmap is a frequency-domain repetition factor, and each bit indicates whether repetition of one or more PRBs is silent; or

The second level frequency-domain repetition bitmap has a length of N12, N12 is equal to a divisor of a frequency-domain repetition factor, and each bit indicates whether or not consecutive Y repetitions of one or more PRBs are muted, a product of Y and N12 is equal to the frequency-domain repetition factor, or each bit indicates whether or not one or more PRBs are muted in a current frequency-domain repetition.

It should be noted that, under the condition that the length of the second-stage frequency domain repeating bitmap is equal to the frequency domain repeating factor, each bit of the second-stage frequency domain repeating bitmap is indicated in a manner of, for example, each bit of the first-stage frequency domain repeating bitmap, which is not described herein again, where the mute indication may use one of the first-stage frequency domain repeating bitmap and the second-stage frequency domain repeating bitmap.

When the length of the second-stage frequency-domain repetition bitmap may be equal to a divisor of the frequency-domain repetition factor and is not equal to the frequency-domain repetition factor, each bit of the second-stage frequency-domain repetition bitmap indicates whether consecutive Y repeated PRBs are silent, and the product of Y and N12 is equal to the divisor of the frequency-domain repetition factor.

Here, each repeated PRB (i.e. the sequentially repeated PRBs) includes all PRBs, and if 30 PRBs are set as SRS resources and the frequency-domain repetition factor is 6, one repeated PRB includes the 30 PRBs.

Specifically, for the case where each bit indicates whether or not consecutive Y frequency-domain repetitions of one or more PRBs are silent: after the frequency domain repetition is divided into N12 groups, each group comprises Y repeated resources, and whether the bitmap repetition is repeated according to the first-stage frequency domain is indicated through the second-stage frequency domain repetition bitmap. For example, if "1" represents non-silence, "0" represents silence, 30 PRBs, the frequency-domain repetition factor is 6, the first-level frequency-domain repetition bitmap is "100100", "100100" represents that the first-time repeated PRBs and the fourth-time repeated PRBs are not silence, the second-level frequency-domain repetition bitmap is "010", that is, after dividing the repetition times (all repeated PRBs) into 3 groups, "010" represents that all the first-group repeated PRBs (i.e., the 1 st repeated PRBs and the 2 nd repeated PRBs) are silent; a second group of repeated PRBs (namely, a 3 rd repeated PRB and a 4 th repeated PRB) sends the SRS according to the silencing mode of the first-level frequency domain repeated bitmap, and because the first-level frequency domain repeated bitmap indicates the 3 rd repeated silencing, and the 4 th repeated silencing, the 3 rd repeated PRB and the 4 th repeated PRB are not silenced; the third set of repeated PRBs (i.e., the 5 th repeated PRB and the 6th repeated PRB) are all muted. Thus, Y is 2 and the product of Y and N12 is equal to 6.

Indicating for each bit the case whether one or more PRBs are silent in the current frequency-domain repetition: after the repetition times are divided into a plurality of groups according to N12 groups, N12 frequency domains included in each group are repeated, and whether the transmission is carried out according to the first-stage frequency domain repetition bitmap is indicated through the second-stage frequency domain repetition bitmap, namely Y is 1. For example, if "1" represents non-silence, "0" represents silence, 30 PRBs, the frequency-domain repetition factor is 6, the first-level frequency-domain repetition bitmap is "100100", "100100" represents that the first-repeated and fourth-repeated PRBs are not silence, the second-level frequency-domain repetition bitmap is "010", that is, after the number of repetitions (all the repeated PRBs) is grouped by 3 repeated PRBs, "010" indicates, for each group of repeated PRBs, that the first repeated PRB in each group of repeated PRBs is silent, the second repeated PRB is repeated according to the first-level frequency-domain repetition bitmap, and the third repeated PRB is silent, then combining the first-level frequency-domain repetition bitmap only indicates that the first-repeated and fourth-repeated transmission are performed, and the 6 repeated PRBs are all silent. Here, Y is 1.

Optionally, for each repeated PRB, under the condition that at least one of the first-stage frequency-domain repetition bitmap and the second-stage frequency-domain repetition bitmap indicates silence, the frequency-domain repetition silence is performed.

Specifically, when the frequency domain repeating silence is determined by the first-stage frequency domain repeating bitmap and the frequency domain repeating silence is determined by the second-stage frequency domain repeating bitmap, or the frequency domain repeating silence is determined by the first-stage frequency domain repeating bitmap and the second-stage frequency domain repeating bitmap, the frequency domain repeating silence may be determined in the manner described above, and details are not repeated here.

As an optional embodiment, in the case that the frequency-domain muting comprises frequency-hopping repeated muting, the muting indication comprises: the first-stage frequency hopping repeated bitmap and/or the second-stage frequency hopping repeated bitmap.

The length of the first-stage frequency hopping repeated bitmap is equal to the frequency hopping number divided by a preset frequency hopping number granularity, and each bit indicates whether one or more frequency hopping is silent; or

The first-stage hopping repetition bitmap has a length of N13, N13 is equal to a divisor of a quotient obtained by dividing a hop count by a preset hop count granularity, and each bit indicates whether or not consecutive G hops of one or more hops are silent, and the product of G and N13 is equal to the hop count.

Under the condition that the length of the first-stage frequency hopping repeated bitmap is equal to the frequency hopping number divided by the granularity of the preset frequency hopping number, if: "1" represents not silence, "0" represents silence, the length of the first-stage frequency hopping repetition bitmap is 4, the first-stage frequency hopping repetition bitmap is "0010," 0010 "represents that the third frequency hopping is not silence, and the first, second and fourth frequency hopping are silence.

In the case where the first level hopping repetition bitmap has a length of N13, N13 is equal to a divisor of the quotient of the hop count divided by the predetermined hop count granularity, and each bit indicates whether or not consecutive G hops of one or more hops are quiet, the product of G and N13 being equal to the hop count, for example: "1" represents no silence, "0" represents silence, and the quotient of the hop count divided by the preset hop count granularity is 20, the length of the first-stage hopping repetition bitmap can be set to be a divisor of 20, such as: 1.2, 4, 5, 10, 20; if the length of the first-stage frequency hopping repeating bitmap is 4, each bit of the first-stage frequency hopping repeating bitmap indicates whether 5 frequency hopping is silent or not; specifically, if the first-stage hopping repetition bitmap is "0101", "0101" indicates that the 6th to 10 th and the 16 th to 20 th hopping repetitions are not muted, and the 1 st to 5 th and the 11 th to 15 th hopping repetitions are muted.

Optionally, the length of the second-stage hopping repetition bitmap is the third repetition factor divided by a preset repetition factor granularity, and each bit indicates whether repetition of one or more hopping frequencies is silent; or,

the second-stage hopping repetition bitmap has a length of N14, N14 is equal to a divisor of a quotient of the third repetition factor divided by the granularity of the preset repetition factor, and each bit indicates whether or not consecutive H repetitions of one or more hopping repetitions are muted, a product of H and N14 is equal to a quotient of the repetition factor divided by the granularity of the preset repetition factor, or each bit indicates whether or not a hopping repetition is muted at the present hopping repetition.

Here, the third repetition factor may be a hopping repetition factor.

It should be noted that, under the condition that the length of the second-stage frequency hopping repetition bitmap is equal to the quotient of the third repetition factor divided by the preset repetition factor granularity, each bit of the second-stage frequency hopping repetition bitmap is indicated as each bit of the first-stage frequency hopping repetition bitmap, which is not described herein again, and here, the silence indication may use one of the first-stage frequency hopping repetition bitmap and the second-stage frequency hopping repetition bitmap.

When the length of the second-stage hopping repetition bitmap may be equal to a divisor of a quotient obtained by dividing the third repetition factor by the preset third repetition factor granularity and is not equal to the quotient, each bit of the second-stage hopping repetition bitmap indicates whether consecutive H repeated hops are quiet, and the product of H and N14 is equal to a divisor of a quotient of the third repetition factor and the preset repetition factor granularity. Here, each repeated frequency hopping (i.e. sequentially repeated frequency hopping) includes all frequency hopping, and if 100 frequency hopping is set as SRS resource, the third repetition factor is 20, and the preset repetition factor granularity is 2, then one repeated frequency hopping includes the 100 frequency hopping.

Specifically, a case will be described where each bit indicates whether or not consecutive H hop repetitions of one or more hop repetitions are muted: after repeating the hopping into N14 groups, each group then includes H repeated hops. For example, if "1" represents not silence, "0" represents silence, the third repetition factor is 20, and the predetermined repetition factor granularity is 2, the length N14 of the second-stage hopping repetition bitmap may be: 1.2, 5, 10, assuming N14 is 5, then H is 2, so that the second stage hopping repetition bitmap is "10010", which "10010" indicates that the first, second, seventh, eighth, eleventh, twelfth, seventeen, and eighteen hopping repetitions are not muted, and the other hopping repetitions are muted.

Indicating for each bit the case whether one or more hopping frequencies are silent at the current hopping repetition: after the number of repetitions is divided into groups of N14, N14 hopping repetitions are included by each group. For example, if "1" represents no silence, "0" represents silence, the third repetition factor is 20, and the repetition factor granularity is 2, the length N14 of the second stage hopping repetition bitmap may be: 1.2, 5, 10, assuming N14 is 5, then H is 2, so that the second stage hopping repetition bitmap is "10010", which "10010" indicates that the first, fourth, sixth, ninth, eleventh, fourteen, sixteen and nineteen hopping repetitions are not muted, and the other hopping repetitions are muted.

For each PRB with repeated frequency hopping, under the condition that at least one of the first-stage frequency hopping repeated bitmap and the second-stage frequency hopping repeated bitmap indicates silence, the frequency hopping repeated silence is carried out.

It should be noted that, the process of determining the repeated silence of the frequency hopping only through the silence indicated by the first-stage frequency hopping repeated bitmap and determining the repeated silence of the frequency hopping only through the silence indicated by the second-stage frequency hopping repeated bitmap is not described herein again as described above.

Here, description is made only on the determination of the muting of the hop repetition by the first-stage hop repetition bitmap and the second-stage hop repetition bitmap:

the first method is as follows: determining the repeated silence of frequency hopping by performing logic and processing on each bit of the first-stage frequency hopping repeated bitmap and each bit of the second-stage frequency hopping repeated bitmap; namely: when the bit of the first-stage frequency hopping repeated bitmap indicates that the first-stage frequency hopping repeated bitmap is not silent and the bit of the second-stage frequency hopping repeated bitmap indicates that the second-stage frequency hopping repeated bitmap is not silent, the frequency hopping repetition is not silent.

The second method comprises the following steps: determining the repeated silence of frequency hopping by performing logic or processing on each bit of the first-stage frequency hopping repeated bitmap and each bit of the second-stage frequency hopping repeated bitmap; namely: and when any one of the bit of the first-stage frequency hopping repeating bitmap and the bit of the second-stage frequency hopping repeating bitmap indicates that the data is not silent, the frequency hopping repeating is not silent.

For example, when the first-stage hopping repetition bitmap is "0010" and the second-stage hopping repetition bitmap is "1010", if the first-stage hopping repetition bitmap is a logical and, then the first-stage hopping repetition bitmap is not muted only on the 3 rd hopping repetition; if logical or, there is no silence on 1 st and 3 rd hop repetitions.
