Description

Positioning reference signal transmission method, device and equipment

Technical Field

The application belongs to the technical field of communication, and particularly relates to a method, a device and equipment for transmitting a positioning reference signal.

Background

In current Positioning technologies, positioning Reference Signal (PRS) configurations can be flexibly adjusted, such as increasing or decreasing bandwidths, to meet the requirements of one or more terminals for Positioning.

However, the PRS configuration is adjusted to correspond to a plurality of Transmission Reference Points (TRPs), which cause interference in signal Transmission. For example: and (4) adjusting the PRS configuration (the central frequency point of the PRS is unchanged, the bandwidth is increased, and the bandwidth is changed from 20MHz to 100 MHz), all TRPs in one area transmit the PRS with the bandwidth of 100MHz, and the TRPs outside the area still transmit the PRS with the bandwidth of 20 MHz. Thus, TRPs located at the edge of the region may cause interference to terminals outside the region.

A positioning reference signal transmission method provided by the embodiments of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.

The method of the embodiment of the present application is applied to a terminal, which may be User Equipment (UE), such as an access terminal, a subscriber unit, a subscriber station, a mobile station, a remote terminal, a mobile device, a user terminal, a wireless communication device, a user agent, or a user equipment. The terminal may also be a cellular telephone, a cordless telephone, a Session Initiation Protocol (SIP) phone, a Wireless Local Loop (WLL) station, a Personal Digital Assistant (PDA), a handheld device having wireless communication capabilities, a computing device, or other processing device connected to a wireless modem, a vehicle mounted device, a wearable device.

As shown in fig. 2, a method for transmitting a positioning reference signal according to an embodiment of the present application is applied to a terminal, and includes:

step 201, obtaining a silence instruction sent by a network side device; wherein the silence indication comprises at least one of:

resource silencing;

frequency domain silence;

time-domain muting.

Here, the muting pattern (muting pattern) is transmitted by the LMF, and specifically includes at least one of resource muting, frequency-domain muting and time-domain muting, i.e., indicates that the PRS is not transmitted in one of at least partial frequency-domain position and at least partial time-domain position of one or more resources (resources).

Step 202, receiving a positioning reference signal according to the silence indication.

Optionally, receiving the positioning reference signal according to the muting indication includes: according to the indication, the UE may receive the PRS at a location where the PRS is actually transmitted, but not at an invalid location.

In this step, after the muting indication is obtained in step 201, the positioning reference signal can be received according to the muting indication.

Thus, according to step 201 and step 202, the terminal applies the method of the embodiment of the present application, after obtaining the muting indication of the network side device, the terminal receives the PRS according to the muting indication, and since the muting indication can indicate that the sending of the PRS performs at least one of resource muting, frequency domain muting and time domain muting, the terminal can not receive the PRS at the corresponding muting position, thereby avoiding the interference of the PRS.

For example, in a scenario where on-demand (on-demand) positioning requires higher accuracy (corresponding configuration requires increasing PRS bandwidth, increasing PRS resource repetition times, increasing PRS symbol number, increasing PRS occurrence frequency (decreasing period), etc.), and requires lower latency (corresponding configuration requires increasing PRS occurrence frequency), as shown in fig. 3, the LBS adjusts the PRS setting of the on-demand positioning region 301 according to a positioning request, and if the PRS period is changed from 160ms to 80ms, and the PRS period of the peripheral region 302 is still 160ms, an additional PRS pointing to the peripheral region 302 is sent by a TRP at the edge of the on-demand positioning region 301, which may cause interference to transmission of terminals in the peripheral region 302. The LBS may determine a silence indication when the silence indication indicates that the on demand positioning region does not transmit PRSs at least a partial frequency domain location and/or at least a partial time domain location of the one or more resources. Thus, by obtaining the silence indication of the LBS and receiving the PRS according to the silence indication, the terminal in the peripheral area 302 can avoid interference caused by the influence of setting and adjusting the PRS by applying the method of the embodiment of the present application.

Similarly, in a scenario where the on demand positioning requires lower power consumption (corresponding configuration requires to reduce PRS bandwidth, PRS resource repetition times, PRS symbol number, PRS occurrence frequency (increase period), and the like), and requires lower latency (corresponding configuration requires to reduce PRS symbol number, and the like), as shown in fig. 4, the LBS adjusts the PRS setting of the on demand positioning region 401 according to the positioning request, and if the PRS period is changed from 80ms to 160ms and the PRS period of the peripheral region 402 is still 80ms, the PRS pointing to the on demand positioning region 401 sent by the TRP at the edge of the peripheral region 402 will interfere with the transmission of the terminal of the on demand positioning region 401. The LBS may determine a silence indication when the silence indication indicates that the on demand positioning region does not transmit PRSs at least a partial frequency domain location and/or at least a partial time domain location of the one or more resources. Thus, by applying the method of the embodiment of the present application, the terminal in the on demand positioning area 401 can avoid interference caused by the influence of setting and adjusting the PRS by obtaining the silence indication of the LBS and receiving the PRS according to the silence indication.

In this embodiment, silence may also be understood as silence.

It should be noted that the LMF may determine the silence indication in any one of the following manners:

a) Determining according to all or part of PRS resource information reported by a base station gNB in advance;

optionally, for one PRS resource, at least one of the following needs to be reported:

a) The beam direction: at least one of the horizontal angle, vertical angle, angular granularity, etc. of the beam.

Wherein the angular particle size comprises at least one of:

integral angular particle size: the integer angular granularity may be 1 °,2 °,5 °, etc., such as: when the granularity is 1, the angle can be determined according to 0,1,2, \8230, 360, and when the granularity is 2, the angle can be determined according to 0,2,4, \8230, 360;

fractional angle particle size: the fractional angle particle size can be 0.1 °,0.2 °,0.5 °, etc.; wherein, when the integral angle granularity is 1, in order to improve the angle precision, can increase the granularity of decimal, to certain angle, can be accurate to the decimal, for example: when the granularity is 0.1 degree, the angle can be determined according to the modes of 1.1,1.2,1.3, \8230, 1.9, 2.0; at a grain size of 0.2 deg., the angle can be determined in the manner of 1.2,1.4,1.6, \ 8230;, 2.0.

b) resource identification: the resource identifier includes at least one of: a transmission reception point Identifier (TRP ID), a Physical Cell Identifier (PCI), an NR Cell Global Identifier (NCGI), a resource set Identifier (resource set ID), a resource Identifier (resource ID), a frequency layer Identifier (location frequency layer ID), a band Identifier (band ID), a carrier Identifier (carrier ID), and a serving Cell Identifier (serving Cell ID).

Wherein, the interpretation of the PRS resource identifier can be used to interpret all PRS resource identifiers in their entirety.

c) Local Coordinate System (LCS) and Global Coordinate System (GCS) transformation parameters: the conversion parameters at least comprise a bearing angle alpha, a declination angle beta and a tilt angle gamma of the PRS transmitting antenna panel. It should be noted that if the information such as the beam direction and the like adopts the TRP local coordinate, the conversion parameter needs to be reported; if the information such as the beam direction adopts GCS coordinates, the parameters do not need to be reported.

B) The LBS indicates to the gNB the PRS resource reporting for a certain range of directions (or angles). And the gNB feeds back the resource identifier corresponding to the network side equipment according to the indicated direction.

Optionally, the direction range indication comprises at least one of:

a) Horizontal angle information: comprising at least one of: a horizontal angle measurement reference, a start angle, an angle range and an end angle; the angle measurement reference may be based on the geographical direction north, and the angle measurement reference may be measured in the counterclockwise direction, where the angle range is: 0 ° to 359 °; the end angle indicates which angle ends, ranging from 0 ° to 60 °.

b) Vertical angle information: comprising at least one of: measuring a reference, a starting angle, an angle range and an ending angle of a vertical angle; wherein the vertical angle measurement reference may be relative to the zenith, 0 ° denoting the zenith, 90 ° denoting the horizontal direction, in the range of 0 ° to 180 °.

c) Particle size of angle (same as in mode a): including at least one of integer angle granularity and fractional angle granularity.

In this embodiment, in the above manner, the silence indication determined by the LMF may directly indicate silence, reflect silence by indicating non-silence, or indicate both of them.

Optionally, in a case that the muting indication includes resource muting, the muting indication is used to indicate that the positioning reference signal is muted on a first resource; wherein,

the first resource is one or more resources in a first set of positioning reference signal resources at a first target transmission receiving point.

As such, the one or more resource sets may be indicated as being silent or non-silent with respect to one or more resources in a first set of positioning reference signal resources (PRS resource sets) under a first target transmission reception point. Specifically, to avoid interference at the edge, the first target transmission reception point (i.e., the first target TRP) is an edge TRP in the area where the PRS configuration is adjusted.

Optionally, the first resource may also be one of:

all resources in a tenth positioning reference signal resource set under a ninth target transmission receiving point;

locating all resources within the frequency layer with the fourth target;

the tenth target transmits all resources under the receiving point. That is, the first resource may also be all resources of the tenth PRS resource set, and the tenth PRS resource set may be other PRS resource sets under the first target TRP, or may also be PRS resource sets under other target TRPs; locating all resources within the frequency layer with the fourth target; and at least one of the total resources under the tenth target transmission reception point.

Here, the resource set may be indicated by at least one of TRP ID, PRS resource set ID, frequency layer ID. The positioning frequency layer may be indicated by a frequency layer ID or by a bitmap, where the bitmap length is equal to the number of frequency layers, each bit indicating whether or not the frequency layer is the fourth target positioning frequency layer. The TRP may be indicated by at least one of TRP ID, PRS resource set ID, frequency layer ID.

In the solution of the present invention, one or more resources of the resource set of the Y positioning reference signal under the X target transmission receiving point may be understood as: one or more positioning reference signal resources in a certain set of positioning reference signal resources under a certain TRP;

all resources in the yth positioning reference signal resource set under the xth target transmission receiving point can be understood as: under a certain TRP, all resources in a certain positioning reference signal resource set;

all resources within the xth target positioning frequency layer can be understood as: all resources of a certain positioning frequency layer;

all resources under the xth target transmission receiving point can be understood as: all resources under a certain transmission reception point.

Here, the first PRS resource set may be indicated by at least one of a TRP ID, a PRS resource set ID, and a frequency layer ID.

Optionally, the corresponding resource is muted, and the muting indication includes: a resource bitmap or a resource identification information indication.

The length of the resource bitmap is N1, N1 is equal to the number of resources in the first positioning reference signal resource set divided by a preset resource granularity, and each bit indicates the corresponding resource silence.

Here, the size of the preset resource granularity indicates the number of (consecutive) resources represented by 1bit in the bitmap. Optionally, the default N1 is equal to the number of PRS resources in the PRS resource set or the preset resource granularity is 1.

Certainly, the preset resource granularity is greater than or equal to 1, the resource corresponding to the bit is a resource with preset resource granularity, that is, each bit indicates one or more resource silences, and the specific number of resources is equal to the preset resource granularity, where the resources with preset resource granularity may be multiple continuous resources. For example, if the number of resources in the first positioning reference signal resource set is 20, and the preset resource granularity is 5, N1=4, and if the bit is 0 to indicate no transmission and the bit is 1 to indicate transmission, the resource bitmap "1000" indicates that only the first 5 resources of the 20 resources transmit PRS. Of course, a bit of 0 may indicate transmission, and a bit of 1 may indicate no transmission. The preset resource granularity may be dictated by the network device and/or agreed upon by the protocol.

Or the length of the resource bitmap is N1, and N1 is equal to the divisor of the number of resources in the first positioning reference signal resource set. The number represented per bit in a Bitmap is the number of H1 (contiguous) resources. H1 is equal to the number of resources in the first set of positioning reference signal resources divided by N1. Optionally, default N1 is equal to the number of PRS resources in the PRS resource set.

Or the length of the resource bitmap is N1, and N1 is equal to the divisor of the number of resources in the first positioning reference signal resource set. The number represented per bit in the Bitmap is the number of H1 (contiguous) resources. H1 may further be dictated by the network and/or agreed upon. Wherein, the product of N1 and H1 is also a divisor of the number of resources in the first SRS resource set. Optionally, default N1 is equal to the number of PRS resources in the PRS resource set. For example, the number of PRS resources in the PRS resource set is 32, N1 is 4, and H1 is 2; then '1000' indicates that the 1,2 th resource transmits PRS, the 9,10 th resource transmits PRS, the 17,18 th resource transmits PRS, and the 25,26 th resource transmits PRS.

Wherein the resource identification information includes:

a reference resource identification and a target resource number; or,

silent all resource identification; or,

the full resource identity of the non-silent resource.

In the case that the resource identifier information includes a reference resource identifier and a target resource number, the target resource number is the number of consecutive silence resources to be indicated by the silence indication, and the reference resource identifier is an identifier of a certain resource in the consecutive silence resources, so that the terminal can know that the target resource number of resources including the reference resource corresponding to the reference resource identifier is silent, for example: if the number of the target resources is C, the silent resource corresponding to the resource identification information may be: the reference resource identifies the corresponding resource and the consecutive C-1 resources before the corresponding resource; the reference resource identifies the corresponding resource and the subsequent continuous C-1 resources; or the reference resource mark corresponds to the resource and the C-D resources before the resource and the D-1 resources after the resource corresponding to the reference resource mark. Of course, the resources corresponding to the reference resource identifier and the target resource number may also be used to indicate non-silent resources (i.e. resources for normally transmitting PRS). Of course, the resource identification information may include multiple sets of reference resource identifications and target resource numbers, i.e. the case where there is no continuity between the multiple sets of resources but the resources within each set are continuous.

It should be noted that the reference Resource identifier and the number of target resources may be encoded and represented by a Resource Indication/indicator Value (RIV), or may be directly indicated.

When the resource identifier information includes all resource identifiers of the silent resources or all resource identifiers of the non-silent resources, the terminal can know that the resources corresponding to the resource identifiers in the silent indication are the silent resources or the non-silent resources.

As an optional embodiment, in case that the muting indication comprises time-domain muting, the muting indication is used to indicate that the positioning reference signal is muted in the time domain of the repeated second resource; wherein,

optionally, the second resource is one or more resources in a second positioning reference signal resource set.

As such, one or more resources in the second set of PRS resources, i.e., one or more resources indicating the same set of PRS resources, may be muted or non-muted. The second set of PRS resources may be a set of PRS resources at the first target TRP or at other TRPs than the first target TRP. Of course, the second resource may be the first resource, i.e. a muted resource or a non-muted resource indicated when the muting indication is used to indicate that the resource is muted.

Optionally, the silence indication comprises: a first-stage resource repeating bitmap and a second-stage resource repeating bitmap; alternatively, the silence indication comprises: the first level resource repeats bitmap. Wherein,

the length of the first-stage resource repeating bitmap is equal to a repeating factor, and the ith bit indicates whether the ith repeated resource is silent; an optional repetition factor may be indicated by the high layer parameter 'DL-PRS-ResourceRepetitionFactor'.

The length of the second level resource repetition bitmap is N2, N2 is equal to a divisor of the repetition factor, and each bit indicates whether the second resource is muted on the corresponding repeated resource.

The repetition factor, i.e., the resource repetition factor, indicates the number of times the resource is repeated. The length of the first-stage resource repetition bitmap is equal to the repetition factor, the ith bit indicates whether the ith repeated resource is silent, wherein the ith repeated resource is determined by the position of the bit, if the repetition factor is 4, the first-stage resource repetition bitmap is '1001', the '1' of the first bit corresponds to the first repeated resource, and the '1' of the fourth bit corresponds to the fourth repeated resource. Wherein, the bit of 1 represents that the repeated resource corresponding to the bit is not quiet, and the bit of 0 represents that the repeated resource corresponding to the bit is quiet; or bit 1 represents silence on the repeated resource corresponding to the bit, and bit 0 represents silence on the repeated resource corresponding to the bit.

And for a second level resource repetition bitmap, optionally each bit of said second level resource repetition bitmap indicates whether consecutive M repeated resources are muted, wherein the product of M and N2 is equal to a divisor of the repetition factor. Alternatively, M may be dictated by the network and/or agreed upon by the protocol.

Thus, the length of the second-level resource repeating bitmap may be equal to the repetition factor, and at this time, each bit of the second-level resource repeating bitmap is indicated in a manner similar to that of each bit of the first-level resource repeating bitmap, and details are not repeated here, where the silent indication may use one of the first-level resource repeating bitmap and the second-level resource repeating bitmap.

The length N2 of the second level resource repetition bitmap may be equal to a divisor of the repetition factor, and when the length is not equal to the repetition factor, each bit of the second level resource repetition bitmap indicates whether M consecutive repeated resources are muted, and the product of M and N2 is equal to the divisor of the repetition factor.

Specifically, one way is that after the repetition is divided into N2 groups, each group includes M repeated resources, and whether the repetition of the bitmap is repeated according to the first-level resource is indicated by the second-level resource repetition bitmap. For example, if "1" represents no silence, "0" represents silence, the 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 silent, the second level resource repetition bitmap is "010," i.e., after dividing the number of repetitions (total repeated resources) into 3 groups, "010" represents that the resources of the first group repetition (i.e., the 1 st repeated resources and the 2 nd repeated resources) are all silent; the second group of repeated resources (namely 3 rd repeated resource and 4 th repeated resource) sends PRS according to the silencing mode of the first-stage resource repeated bitmap, and because the first-stage resource repeated bitmap indicates 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, M =2, the product of M and N2 is equal to 6. In this way, the number of consecutive repeated resources, M, represented per bit in the second level resource repetition bitmap is equal to the repetition factor divided by the bitmap length, N2.

As shown in fig. 5, each PRS resource in the graph is a repeated resource, and may include one or more resources. If "1" represents no silence, "0" represents silence, 1 PRS resource, and a repetition factor (DL-PRS-resource repetition factor) is 8, then the first level resource repetition bitmap length is equal to 8, the second level resource repetition bitmap length N2 is a divisor of 8, such as N2=4, and the number of repetitions is divided into 4 groups of 4 where each bit represents the number of consecutive repeated PRS resources M =2. In the second resource repeating bitmap, "1" represents that the group is repeatedly transmitted according to the first-stage resource repeating bitmap; "0" indicates that the set of repeats is mutted in its entirety. For example, the first-level resource repetition bitmap is "10101010", where "10101010" indicates that the first, third, fifth, and seventh repeated resources are not muted, and the second-level resource repetition bitmap is "1000", that is, after the repetition times (all repeated resources) are divided into 4 groups, "1000" indicates that the first group of repeated resources (i.e., the first 2 repeated PRS resources) transmits PRS in the manner of muting the first-level resource repetition bitmap; the second set of repeated resources (i.e., the 3 rd repeated resource and the 4 th repeated resource) are all muted; the third set of repeated resources (i.e., the 5 th repeated resource and the 6th repeated resource) are all muted; the fourth set of repeated resources (i.e., the 7 th repeated resource and the 8 th repeated resource) are all muted.

In another mode, after the repetition times are divided into multiple groups according to N2 groups (the second level resource repetition bitmaps of the multiple groups are the same), the second level resource repetition bitmap indicates whether to transmit according to the first level resource repetition bitmap or not according to the N2 resources included in each group, that is, M =1. For example, if "1" represents no muting, "0" represents muting, 30 resources, the repetition factor is 6, the first-level resource repetition bitmap is "100100", "100100" represents that the first-time repeated resource and the fourth-time repeated resource are not muting, the second-level resource repetition bitmap is "010", that is, after 3 repeated resources (all repeated resources) are grouped by the repetition times, "010" represents that the first repeated resource in each group of repeated resources is muted for each group of repeated resources, the second repeated resource is repeated according to the first-level resource repetition bitmap, the third repeated resource is muted, and then muting is performed again in the same second-level resource repetition muting manner from the fourth repeated resource to the sixth repeated resource. Then combining the first level resource repetition bitmap to only indicate the first repetition and the fourth repetition transmission, and the resources of the 6 repetitions are all silent. Here, M =1.

As shown in fig. 6, if "1" represents no silence, "0" represents silence, 1 PRS resource, and the repetition factor (DL-PRS-resource repetition factor) is 8, in this case, the first level resource repetition bitmap length is equal to 8, and the second level resource repetition bitmap length N2 is a divisor of 8, such as N2=4, the number of repetitions is divided into 2 groups every 4 groups, and each bit represents the number of consecutive repeated PRS resources M =1. Then aiming at a group of second resource repeated bitmaps, a '1' represents that a repeated resource in the group of repeated resources is sent according to the first-stage resource repeated bitmaps; "0" represents that the resources of a certain repetition in the set of repetitions are all muted. For example, the first-level resource repetition bitmap is "11110000", "11110000" indicates that the first, second, third and fourth repeated resources are not muted, the second-level resource repetition bitmap is "1100" indicates that the first 2 resources in the first group of repeated resources (i.e., the first 4 repeated PRS resources) transmit PRSs in a muting manner of the first-level resource repetition bitmap, and the last 2 resources are muted; and the front 2 resources of the second group of repeated resources send PRS according to the silencing mode of the first-stage resource repeating bitmap, and the rear 2 resources are silenced. Combining the 2-level resource repetition bitmap, only the first 2 resources are silent in the final 8 repeated resources.

In another way, the length of the second level resource repetition bitmap is N2, each bit of the second level resource repetition bitmap indicates whether consecutive M repeated resources are silent, the product of M and N2 is equal to a divisor of the repetition factor but not equal to the repetition factor, and M is not equal to 1. In this way, N2 × M repeated resources are in one group, all the repeated PRS resources may be divided into multiple groups, and the second-level repeated bitmaps of each group are the same. Here, M may be dictated by protocol conventions and/or the network.

For example, the repetition factor is 8, and the first level resource repetition Bitmap is indicated as "10101010"; n2=2, m =2, the second level resource repetition bitmap is "10", each bit will be for two repeated resource indications per group. The repeated resources are divided into 2 groups, i.e. the first 4 repeated resources are one group and the last 4 repeated resources are one group. Taking the previous 4 repeated resources as an example, the first-stage resource repetition bitmap '10101010' indicates that the 1 st resource and the 3 rd resource are not silent; further indicating '10' according to the second-level resource repetition Bitmap, repeating the 1 st and 2 nd resources according to the first-level Bitmap, and silencing the 3 rd and 4 th resources; then after combining, the 1 st repeated resource is not muted and the 2,3,4 th repeated resource is muted. Finally reflecting on the total 8 repeated resources, the 1 st and 5 th resources are not muted, and the rest are muted.

Optionally, for each repeated resource, the repeated resource is muted in case at least one of the first level resource repetition bitmap and the second level resource repetition bitmap indicates muting.

That is, the mute indication is used to indicate time-domain muting, and the time-domain muting includes a situation of repeated resource muting, and for a two-level resource repetition bitmap included in the mute indication, a specific implementation of the two-level resource repetition bitmap is adopted. For example, the network configures all PRS resources in a PRS resource set to perform muting in a first level Bitmap manner, and then indicates one or some resource second level bitmaps in the resource set on the basis. And muting the corresponding repeated PRS resources by combining the resources according to the 2-level Bitmap.

Optionally, as an optional embodiment, in a case that the muting indication includes frequency-domain muting, the muting indication is used to indicate that the positioning reference signal is muted on the frequency domain of the third resource; wherein,

the third resource comprises at least one of:

one or more resources in a third set of positioning reference signal resources;

all resources in a fourth positioning reference signal resource set under a second target transmission receiving point;

all resources within the first target positioning frequency layer;

the third target transmits all resources under the receiving point.

As such, frequency-domain muting may be indicated for a third resource that includes one or more resources. Wherein the third resource may be the first resource, i.e. a muted resource or a non-muted resource indicated when the muting indication is used to indicate resource muting, e.g. the third PRS resource set may be the first PRS resource set under the first target TRP. Of course, the third PRS resource set may be other PRS resource sets under the first target TRP, and may also be PRS resource sets under other target TRPs. The fourth PRS resource set may be indicated by at least one of TRP ID, PRS resource set ID, frequency layer (frequency layer) ID. The first target positioning frequency layer may be indicated by a frequency layer ID or by a bitmap, where the bitmap length is equal to the number of frequency layers, each bit indicating whether the frequency layer is the first target positioning frequency layer. The second target TRP and the third target TRP may be indicated by at least one of TRP ID, PRS resource set ID, frequency layer ID.

Optionally, corresponding to frequency domain muting, the muting indication includes: frequency domain bitmap or frequency domain identification information.

The length of the frequency domain bitmap is N3, where N3 is equal to the number of physical resource blocks PRB in the frequency domain where the third resource is located divided by a preset PRB granularity, and each bit indicates whether PRB of the corresponding granularity is silent.

Here, the preset PRB granularity is greater than or equal to 1, the PRBs corresponding to the bits are PRBs with preset PRB granularity, that is, each bit indicates one or more PRB mutes, and the specific number of PRBs is equal to the preset PRB granularity, where the preset PRB granularity resources may be multiple consecutive PRBs. For example, if the number of PRBs in the frequency domain where the third resource is located is 20, and the preset PRB granularity is 4, N3=5, and if the bit is 0 to indicate no transmission and the bit is 1 to indicate transmission, the frequency domain bitmap "10000" indicates that only the first 4 PRBs transmit PRSs out of 20 PRBs. Of course, a bit of 0 may indicate transmission, and a bit of 1 may indicate no transmission.

Alternatively, when configuring the PRS bandwidth, the protocol convention or network indicates the PRB granularity for the PRS bandwidth. For example, when the PRS bandwidth is actually configured, the protocol stipulates 4 PRBs as granularity, indicating the minimum unit of bandwidth. Optionally, the preset PRB granularity in the present scheme may further specify or indicate the PRB granularity for frequency-domain muting on the basis of the PRB granularity. That is, the PRB granularity for frequency-domain muting is an integer multiple of the PRB granularity when the PRS bandwidth is configured. It can be specified or indicated by 2 methods:

(1) In units of PRBs. For example, the PRB granularity when configuring the PRB bandwidth is 4, then the PRB granularity for frequency-domain muting can be an integer multiple of 4, such as 4PRB,8PRB,12PRB, and so on

(2) The PRB granularity for frequency-domain muting is represented by a multiple of the PRB granularity that indicates or specifies the PRS bandwidth. For example, the indication value is 4, and the PRB granularity representing frequency-domain muting is 4 times that of the PRS bandwidth PRB granularity, such as 16PRB.

Wherein the preset PRB granularity may be dictated by protocol conventions and/or by the network.

Wherein the frequency domain identification information includes:

a reference PRB identifier and a target PRB number; or,

all PRB identifications of the silent PRBs; or,

all PRB identities of non-silent PRBs.

Under the condition that the frequency domain identification information includes the reference PRB identification and the target PRB number, the target PRB number is the number of the continuous silent PRBs to be indicated by the silent indication, and the reference PRB identification is the identification of a certain PRB in the continuous silent PRBs, so that the terminal can know the target PRB number of silent PRBs including the reference PRB corresponding to the reference PRB identification, for example: the number of target PRBs is E, and the silent PRBs corresponding to the PRB identification information may be: the reference PRB mark corresponds to a PRB and a previous continuous E-1 PRB; the reference PRB marks the corresponding PRB and the following continuous E-1 PRBs; or the PRB corresponding to the reference PRB identification, E-F PRBs before the PRB and F-1 PRBs after the PRB corresponding to the reference PRB identification. Of course, the PRBs corresponding to the reference PRB identification and the target PRB number may also be used to indicate non-silent PRBs (i.e. PRBs that normally transmit PRSs). Of course, the PRB identification information may include multiple sets of reference PRB identifications and target PRB numbers, i.e. the case where there is no discontinuity between multiple sets of PRBs but there is a continuity of PRBs within each set.

Optionally, the PRB identification or the target PRB number may be used for the frequency-domain silent PRB granularity or the PRB granularity of the PRS bandwidth as a unit.

It should be noted that the reference PRB identification and the target PRB number may be represented by PRB RIV coding or may be directly indicated.

Under the condition that the PRB identification information includes all PRB identifications of the silent PRBs or all PRB identifications of the non-silent PRBs, the terminal can know that the PRB corresponding to the PRB identification in the silent indication is the silent PRB or the non-silent PRB.

Of course, based on the above-mentioned situation that the time-domain muting includes repeated resource muting, for frequency-domain muting, repeated PRB muting is also sent, and the repetition factor is a frequency-domain repetition factor, and may be equal to or different from the time-domain repetition factor. For repeated PRB muting, similarly, the muting indication may also adopt a two-level PRB repeated bitmap, specifically for implementing repeated resource muting, which is not described herein again.

As an optional embodiment, in case that the muting indication comprises time-domain muting, the muting indication is used to indicate that the positioning reference signal is muted on a time-domain symbol of a fourth resource; wherein,

optionally, the fourth resource includes at least one of:

one or more resources in a fifth set of positioning reference signal resources;

all resources in a sixth positioning reference signal resource set under a fourth target transmission receiving point;

all resources within the second target positioning frequency layer;

the fifth target transmits all resources under the receiving point.

As such, the time domain symbol silence may be indicated for a fourth resource comprising one or more resources. Wherein the fourth resource may be the first resource, i.e. a muted resource or a non-muted resource indicated when the muting indication is used to indicate resource muting, e.g. the fifth PRS resource set may be the first PRS resource set under the first target TRP. Of course, the fifth PRS resource set may be other PRS resource sets under the first target TRP, and may also be PRS resource sets under other target TRPs. Here, the resource set may be indicated by at least one of TRP ID, PRS resource set ID, frequency layer ID. The positioning frequency layer may be indicated by a frequency layer ID or by a bitmap, where the bitmap length is equal to the number of frequency layers, each bit indicating whether or not the frequency layer is the second target positioning frequency layer. The TRP may be indicated by at least one of TRP ID, PRS resource set ID, frequency layer ID.

Optionally, the muting indication includes: time domain bitmap or time domain identification information indication.

The length of the time domain bitmap is N4, N4 is equal to the number of symbols of a time slot in the time domain where the fourth resource is located divided by a preset symbol granularity, and each bit indicates whether a corresponding symbol is silent. Wherein, the preset symbol granularity can be indicated by a network and/or agreed by a protocol.

Here, the preset symbol granularity is greater than or equal to 1, the symbols corresponding to the bits are preset symbol granularity symbols, that is, each bit indicates whether one or more symbols are silent, and the specific number of symbols is equal to the preset symbol granularity, where the preset symbol granularity symbols may be a continuous plurality of symbols. For example, if the number of symbols in a time slot in which the fourth resource is located is 6, and the preset symbol granularity is 2, N3=3, and if the bit is 0 to indicate that no transmission is performed and the bit is 1 to indicate that transmission is performed, the frequency domain bitmap "100" indicates that only the first 2 symbols of the 6 symbols transmit PRS. Of course, a bit of 0 may indicate transmission, and a bit of 1 may indicate no transmission.

Specifically, the value of N4 will be described with reference to the combinations of the number of symbols (symbols) and the comb structure size (comb size) shown in table 1 below:

TABLE 1

Take preset symbol granularity L = comb size as an example:

a) In the case of the comb-2,

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

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

when the number of symbols is 6, the length of the time domain bitmap is 3;

when the number of symbols is 12, the time domain bitmap length is 6.

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

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

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

c) In the case of comb-6,

when the number of the symbols is 6, the length of the time domain bitmap is 1;

when the number of symbols is 12, the time domain bitmap length is 2.

d) In the case of the comb-12,

when the number of symbols is 12, the time domain bitmap length is 1.

Exemplified by L being equal to other submultiples of the symbol number. E.g., for comb-12, l =6. Then the time domain bitmap length may be 2. For comb-12, the first 6 symbols or the last 6 symbols may actually be transmitted.

Optionally, as another way of symbol-level muting. The length of the time domain bitmap is N4, the preset symbol granularity is S, and the symbol number represented by each bit in the bitmap is represented. The product of N4 and S is a divisor of the number of symbols of one time slot in the time domain in which the fourth resource is located. In this way, N4 × S symbols are a group, the symbols of one timeslot in the time domain where the fourth resource is located may be divided into one or more groups, and the symbol level bitmaps of each group are the same. The preset symbol granularity S may be indicated by a network and/or agreed by a protocol.

For example, the symbol of the fourth resource in one slot is 12. The Bitmap length is N4=2, and the preset symbol granularity is 2. Thus, the first 4 symbols are 1 group, the 5 th to 8 th symbols are 1 group, the 9 th to 12 th symbols are 1 group, and the 3 groups of bitmaps are the same. When the bitmap is '10', the 1,2,5,6,9,10 th symbols are not muted, and the remaining symbols are muted.

Wherein the time domain identification information comprises:

a reference symbol identification and a target symbol number; or,

all symbol identifications of silence symbols; or,

all symbol identifications of the non-silent symbols.

In the case that the time domain identification information includes reference symbol identifications and a target symbol number, the target symbol number is the number of consecutive mute symbols to be indicated by the mute indication, and the reference symbol identification is an identification of a certain symbol in the consecutive mute symbols, so that the terminal can know that the symbols of the target symbol number including the reference symbol corresponding to the reference symbol identification are muted, for example: if the number of the target symbols is G, the silent symbol corresponding to the symbol identification information may be: the reference symbol identifies the corresponding symbol and consecutive G-1 symbols preceding it; the reference symbol identifies the corresponding symbol followed by consecutive G-1 symbols; or the reference symbol identifies the corresponding symbol and the preceding G-H symbols and the reference symbol identifies the H-1 symbols after the corresponding symbol. Of course, the symbols corresponding to the reference symbol identity and the target symbol number may also be used to indicate non-silent symbols (i.e. symbols for normally transmitting PRS). Of course, the symbol identification information may include multiple sets of reference symbol identifications and target symbol numbers, i.e., where there is no continuity between the sets of symbols but where the symbols within each set are continuous.

For example, the silence start symbol is a start symbol within resource, such as 6 (symbol 0 is resource 1 st symbol); the number of symbols is 6, then the last 6 symbols are muted out of comb-6,12 symbols. Alternatively, the starting symbol of non-mutting is configured as the starting symbol in resource, such as 6; the number of symbols is 6, then comb-6,12 symbols, the last 6 symbols are not muted.

It should be noted that the reference symbol identification and the target symbol number may be represented by the symbol RIV code, or may be directly indicated.

Alternatively, the unit of the reference symbol identification and the target symbol number here may be a preset symbol granularity.

Under the condition that the symbol identification information includes all symbol identifications of the silent symbols or all symbol identifications of the non-silent symbols, the terminal can know that the symbols corresponding to the symbol identifications in the silent indication are silent symbols or non-silent symbols.

Of course, based on the above-mentioned situation that the time-domain muting includes repeated resource muting, for the time-domain symbol muting, there is also sent a repeated symbol muting, and the repetition factor is a symbol repetition factor, which may be equal to or different from the time-domain repetition factor. For repeated symbol muting, similarly, the muting indication may also adopt a two-level symbol repetition bitmap, and specifically, for implementation of repeated resource muting, details are not repeated here.

As an optional embodiment, in a case that the muting indication includes time-domain muting, the muting indication is used for indicating that the positioning reference signal is muted on a period of a fifth resource; wherein,

the fifth resource is one or more resources in a seventh positioning reference signal resource set under a sixth target transmission and reception point.

As such, a periodic time-domain silence may be indicated for a fifth resource that includes one or more resources. Wherein the fifth resource may be the first resource, i.e. a muted resource or a non-muted resource indicated when the muting indication is used to indicate resource muting, e.g. the seventh PRS resource set may be the first PRS resource set under the first target TRP. Of course, the seventh PRS resource set may be other PRS resource sets under the first target TRP, and may also be PRS resource sets under other target TRPs. Here, the resource set may be indicated by at least one of TRP ID, PRS resource set ID, frequency layer ID. The TRP may be indicated by at least one of TRP ID, PRS resource set ID, frequency layer ID.

Optionally, the fifth resource may also be one of:

all resources in an eleventh positioning reference signal resource set under an eleventh target transmission receiving point;

locating all resources within the frequency layer by a fifth target;

the eleventh target transmits all resources under the reception point.

That is, the fifth resource may also be all resources of the eleventh PRS resource set, and the eleventh PRS resource set may be other PRS resource sets under the sixth target TRP, or may also be PRS resource sets under other target TRPs; locating all resources within the frequency layer by a fifth target; and at least one of the total resources under the eleventh target transmission reception point.

Here, the resource set may be indicated by at least one of TRP ID, PRS resource set ID, frequency layer ID. The positioning frequency layer may be indicated by a frequency layer ID or by a bitmap, where the bitmap length is equal to the number of frequency layers, each bit indicating whether or not the frequency layer is the fifth target positioning frequency layer. The TRP may be indicated by at least one of TRP ID, PRS resource set ID, frequency layer ID.

Optionally, the silence indication includes: a first-stage periodic bitmap and a second-stage periodic bitmap; alternatively, the mute indication comprises: the first stage is periodic bitmap.

Optionally, the length of the first-stage period bitmap is equal to a preset threshold, and each bit indicates whether the corresponding period is silent.

Wherein, the bit number of the first-stage bitmap is 1 to represent that one or more periods corresponding to the bit number are not quiet, and the bit number of the first-stage bitmap is 0 to represent that one or more periods corresponding to the bit number are quiet; or bit 1 represents that one or more periods corresponding to the bit are silent, and bit 0 represents that one or more periods corresponding to the bit are not silent. For example, the length of the first-stage period bitmap is 32, and each bit represents 4 consecutive PRS period instances, then the first-stage period bitmap can control whether consecutive 96 periods are quiet or not. When the PRS period exceeds 96 periods, the first-stage period bitmap can be circularly used for carrying out silence indication.

Optionally, the length of the second-stage period bitmap is equal to the length of the first-stage period bitmap, and each bit indicates whether a corresponding period is silent.

Here, the second-stage period bitmap refers to the design of the first-stage period bitmap, and the period corresponding to each bit may be one or more periods, which are also the same as the first-stage period bitmap. For example, the network device indicates all PRSs in a certain PRS resource set according to a first period Bitmap through the first period Bitmap, and then indicates one or several second periods bitmaps of the resource set on the basis of the first period Bitmap. These resources mute the PRS period in a 2-level Bitmap combining manner.

Optionally, the length of the second-stage period bitmap is N5, and N5 is equal to a divisor of the number of periods represented by each bit in the first-stage period bitmap.

Optionally, in the second-stage period bitmap, each bit indicates whether or not consecutive K periods are silent, wherein,

the product of N5 and K is a divisor of the number of periods each bit represents in the first stage period bitmap.

Alternatively, K may be dictated by the network and/or agreed upon by the protocol.

Here, the length of the second-stage period bitmap is equal to a divisor of the number of periods represented by each bit in the first-stage period bitmap, at which time each bit of the second-stage period bitmap indicates whether or not consecutive K periods are silent.

Specifically, one way is to combine the first-stage period bitmap, and the second-stage period bitmap indicates whether each period is silent in a plurality of consecutive periods represented by each bit in the first-stage period bitmap, where K is equal to the number of periods represented by each bit in the first-stage period bitmap divided by N5. As shown in FIG. 7, DL-PRS-MutingBitRepetitionisFactor is 4, which means that the first-stage period bitmap represents 4 periods per bit. If the length of the second-stage period bitmap is equal to 4, the second-stage period bitmap may further indicate whether 4 periods are muted. In this example, the bitmap length N5=4, and each bit represents the number of cycles K =1.

Another example is as follows: assuming that the length of the PRS first-stage periodic bitmap is 32, and each bit in the first-stage periodic bitmap represents 16 consecutive periods, the length of the second-stage bitmap may be: 1.2, 4, 8, and 16, if the length of the second level bitmap is 4, when the first level period bitmap is 010000000 \82300, the 17 th to 32 th transmission periods of the PRS represented by the second bit in the first level period bitmap are not muted (e.g., normal transmission); when the second-stage period bitmap is 1001, the first-stage period bitmap indicates that a plurality of periods (from a 17 th transmission period to a 32 th transmission period) which are not silent are executed, and transmission or muting is performed according to the second-stage period bitmap, and under the condition that each bit in the second-stage period bitmap indicates whether continuous K (K = 4) periods of one or more resources are silent, specifically, the 17 th transmission period to the 20 th transmission period represented by the second bit in the second-stage period bitmap are not silent, and the 29 th transmission period to the 32 th transmission period represented by the fourth bit in the second-stage period bitmap are not silent.

Another way is to group N5 consecutive periods into one group with a length N5 of the second-stage period bitmap, and by combining the periods of non-silence indicated by the first-stage period bitmap, for the periods of non-silence, the second-stage period bitmap may further indicate whether each period in each group of periods is muted, where K is equal to 1. The bitmaps are the same for groups with N5 x 1 cycle number.

As shown in fig. 8, the DL-PRS-muttingbitratepetitionfactor' is 4, which means that each bit in the first-stage period bitmap represents 4 periods. If the length of the second-stage period bitmap is equal to 2, 2 continuous periods form a group, and for each group of periods, whether each period is muted or not is indicated according to the second-stage period bitmap. In this example, the bitmap length N5=2, and each bit represents the number of cycles K =2. The number of cycles represented by each Bit in the first-stage cycle bitmap is divided into 2 groups, and the second-stage cycle bitmaps of the 2 groups are the same.

Another example is as follows: assuming that the length of the PRS first-stage periodic bitmap is 32, each bit in the first-stage periodic bitmap represents 16 consecutive periods, and then the length of the second-stage bitmap may be: 1.2, 4, 8, and 16, if the length of the second level bitmap is 4, when the first level period bitmap is 010000000 \82300, the 17 th to 32 th transmission periods of the PRS represented by the second bit in the first level period bitmap are not muted (e.g., normal transmission). Grouping according to the length of the second-stage period bitmap, namely, taking every 4 periods as a group, wherein 4 periods of each group determine whether to silence according to the bit of the second group bitmap, when the second-stage period bitmap is 0100, combining the 17 th sending period to the 32 th sending period obtained by the first-stage period bitmap, and further obtaining 18 th, 22 th, 26 th and 30 th periods from the second-stage period bitmap. Here K =1, i.e. the second period bitmap represents 1 period per bit.

The other way is that the length of the second-stage period bitmap is N5, and each bit indicates whether consecutive K periods are silent. Wherein the product of N5 and K is a divisor of the number of cycles represented by each bit in the first stage cycle bitmap but is not equal to the number of cycles represented by each bit, and K >1. Optionally, the bitmaps are the same for groups of N5 x K cycles.

For example, each bit of the first-stage period represents 32 periods, the bitmap length N5=4 of the second-stage period, each bit represents 2 consecutive periods, and K =2. Then the 32 consecutive cycles are divided into 32/(N5 × K) =4 groups of 8 consecutive cycles in each group. The second-stage period bitmaps of these 4 groups are identical.

Specific examples are as follows: assuming that the length of the PRS first-level periodic bitmap is 32, each bit in the first-level periodic bitmap represents 16 consecutive periods, and then the length of the second-level bitmap may be: 1.2, 4, 8, and 16, if the length of the second level bitmap is 4, when the first level period bitmap is 010000000 \82300, the 17 th transmission period to the 32 th transmission period of the PRS represented by the second bit in the first level period bitmap are not muted (e.g., normal transmission). The length of the second-stage period bitmap is 4, each Bit represents 2 periods, namely, each 8 continuous periods is taken as 1 group, and the two periods are divided into 2 groups. When the second-stage period bitmap is 0100, the periods from the 17 th transmission period to the 32 th transmission period obtained by combining the first-stage period bitmap are not silent, and the second-stage period bitmap can further obtain periods from 19 th, 20 th, 27 th and 28 th.

Optionally, in this embodiment, for each period, under the condition that at least one of the first-stage period bitmap and the second-stage period bitmap indicates silence, the period silence is performed on the condition that the period silence indicates silence

That is, the silence indication is used to indicate time-domain silence, and the time-domain silence includes a periodic time-domain silence, for a specific implementation of a two-stage periodic bitmap included in the silence indication, as described above, one of the two may be used to determine the periodic time-domain silence, and both may be used to determine the periodic time-domain silence together. For example, the network configures all PRS resources in a PRS resource set to perform muting according to a first-level periodic Bitmap, and then indicates one or some resource second-level periodic bitmaps in the resource set on the basis. And the resources are silenced in a corresponding period according to a 2-level Bitmap combination mode.

As another alternative embodiment, the muting indication may also be used to indicate muting of PRS ports. A port muting of one or more PRS resources may be indicated. For a specific PRS resource, if there are multiple ports, the network side device may instruct multiple or a certain port therein to be muted.

Optionally, the port silence may be indicated by a bitmap, for example, the length of the bitmap is equal to the number of ports, each bit in the bitmap represents one port, and a bit of 1 represents normal transmission or silence of the port; or directly by port identification, such as port quiesce indicating some identification (e.g., port number).

Optionally, the one or more resources may be a sixth resource, the sixth resource including at least one of:

one or more resources in an eighth set of positioning reference signal resources;

all resources in a ninth positioning reference signal resource set under a seventh target transmission receiving point;

locating all resources within the frequency layer by the third target;

and transmitting all resources under the receiving point by the eighth target.

As such, PRS port muting may be indicated for a sixth resource that includes one or more resources. Wherein the sixth resource may be the first resource, i.e. a muted resource or a non-muted resource indicated when the muting indication is used to indicate the resource is muted, e.g. the ninth PRS resource set may be the first PRS resource set under the first target TRP. Of course, the ninth PRS resource set may be other PRS resource sets under the first target TRP, and may also be PRS resource sets under other target TRPs. Here, the resource set may be indicated by at least one of TRP ID, PRS resource set ID, frequency layer ID. The positioning frequency layer may be indicated by a frequency layer ID or by a bitmap, where the bitmap length is equal to the number of frequency layers, each bit indicating whether a frequency layer is a third target positioning frequency layer. The TRP may be indicated by at least one of TRP ID, PRS resource set ID, frequency layer ID.

In addition, as an alternative embodiment, before step 202, the method further includes:

and acquiring the indication information of whether the silence indication is frequency-domain silence.

Here, by acquiring the indication information, it can be known whether the acquired mute indication is frequency-domain mute.

Optionally, the network side device indicates whether the multicasting is frequency domain multicasting through the target parameter, and when the parameter exists in the acquired type information, the multicasting type is frequency domain multicasting; otherwise the default type of muting is normal muting. Or, the type of muting is indicated by 1bit in the type information, there are 2 types of muting, frequency domain muting and conventional muting, 1 of which is indicated.

Here, it is also possible to know which one or more of resource muting, time-domain muting, and frequency-domain muting is/are specifically indicated by acquiring type information of the muting indication (the type information includes at least one of resource muting, time-domain muting, and frequency-domain muting).

In this embodiment, for the silence indication, the LMF may position the LPP information to notify the terminal through long term evolution; or, the LMF notifies the gNB through LPPa information, and then the gNB notifies the terminal through at least one of multimedia control signaling MAC CE, downlink control signaling DCI, radio resource control signaling RRC, and broadcast signaling.

Before the positioning-involved base stations or TRPs send PRSs, receiving a silence indication sent by an LMF, and sending the PRSs according to the indication. Where the LMF may be indicated by LPPa signaling or other signaling.

To sum up, according to the method of the embodiment of the present application, after the muting indication of the network side device is obtained, the PRS is received according to the muting indication, and since the muting indication can indicate that the sending of the PRS performs at least one of resource muting, frequency domain muting and time domain muting, the terminal can not receive the PRS at the corresponding muting position, thereby avoiding the interference of the PRS.

As shown in fig. 9, a positioning reference signal transmission method according to an embodiment of the present application is applied to a network device, and includes:

the muting indication is used for indicating that the positioning reference signal is muted in a time domain of a repeated second resource, and the muting indication includes: a first-stage resource repeating bitmap and a second-stage resource repeating bitmap; the length of the first-stage resource repeating bitmap is equal to a repeating factor, and the ith bit indicates whether silence exists on the ith repeated resource; the length of the second level resource repetition bitmap is N2, N2 is equal to a divisor of the repetition factor, and each bit indicates whether the second resource is silent on the corresponding repeated resource; when at least one of the first-stage resource repeating bitmap and the second-stage resource repeating bitmap indicates silence, the repeated resources are silent; wherein in the second level resource repetition bitmap, each bit indicates whether consecutive M repeated resources are muted, wherein the product of M and N2 is equal to a divisor of a repetition factor;

and/or the presence of a gas in the gas,

the muting indication is used for indicating that the positioning reference signal is muted on a period of a fifth resource, and the muting indication includes: a first-stage periodic bitmap and a second-stage periodic bitmap; the length of the first-stage period bitmap is equal to a preset threshold value, and each bit indicates whether the corresponding period is silent or not; the length of the second-stage period bitmap is equal to the length of the first-stage period bitmap, and each bit indicates whether the corresponding period is silent or not, or the length of the second-stage period bitmap is N5, and N5 is equal to a divisor of the number of periods represented by each bit in the first-stage period bitmap; for each period, the period is silent under the condition that at least one of the first-stage period bitmap and the second-stage period bitmap indicates silence; in the second-stage period bitmap, each bit indicates whether continuous K periods are silent, wherein the product of N5 and K is a divisor of the number of periods represented by each bit in the first-stage period bitmap.

24. A communication device comprising a processor, a memory, and a program or instructions stored on the memory and executable on the processor, the program or instructions, when executed by the processor, implementing the positioning reference signal transmission method according to any one of claims 1 to 16 or the steps of the positioning reference signal transmission method according to any one of claims 17 to 21.

25. A readable storage medium, characterized in that a program or instructions are stored thereon, which program or instructions, when executed by a processor, implement the positioning reference signal transmission method according to any one of claims 1 to 16, or the steps of the positioning reference signal transmission method according to any one of claims 17 to 21.
