Description

Information processing method, device, equipment and computer readable storage medium

Technical Field

The present invention relates to the field of communications technologies, and in particular, to an information processing method, an apparatus, a device, and a computer readable storage medium.

Background

In uplink positioning, the SRS (Sounding Reference Signal ) signal is an effective positioning reference signal, because the SRS signal can be configured independently based on different UEs (User Equipment), different bandwidths and time domain resources can be configured, and the SRS can be transmitted in different beam directions.

However, in the uplink positioning operation, the SRS transmitted by the terminal needs to reach different base stations, and the distances between the different base stations and the terminal are different, so that different transmission powers are required; likewise, different base stations require the terminal to transmit different beam directions in different geographic directions of the terminal. More importantly, when the SRS signal reaches the base station receiver, the base station needs to be able to accurately monitor and detect the SRS signal, so as to further estimate the time delay and angle.

In the process of interception and detection, a key condition is that SRS signals suffer lower interference and higher received signal-to-noise ratio, so that the accuracy and precision of positioning can be ensured. Therefore, how to improve the positioning accuracy of the uplink positioning reference signal is a major consideration.

Detailed Description

The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

Referring to fig. 1, fig. 1 is a flowchart of an information processing method provided in an embodiment of the present invention, which is applied to a terminal, as shown in fig. 1, and includes the following steps:

step 101, determining a target uplink positioning reference signal resource or a resource set according to the resource transmission pattern, wherein the target uplink positioning reference signal resource or the resource set is configured to be in a sending state.

In an embodiment of the present invention, the resource transmission Pattern includes a Muting Pattern (Muting Pattern), and the transmission state includes a non-Muting state.

Wherein the silence pattern includes a bitmap (bitmap) of length N, N being an integer greater than or equal to 1. Meanwhile, the muting pattern is used for periodic uplink positioning reference signals. Specifically, the uplink positioning reference signal comprises SRS-Pos.

In a specific application, the muting pattern includes any one of the following forms of muting patterns:

first form: the silent pattern is a first silent pattern, and the first silent pattern corresponds to a first bitmap; each bit in the first bitmap corresponds to at least one contiguous instance of one set of uplink positioning reference signal resources.

In this form, for the first bitmap, if a first set of uplink positioning reference signal resources instance is muted in the first bitmap, all uplink positioning reference signal resources in the first set of uplink positioning reference signal resources instance are muted.

Second form: the silence pattern is a second silence pattern, and the second silence pattern corresponds to a second bitmap; each bit in the second bitmap corresponds to a single repetition index of each uplink positioning reference signal resource in an uplink positioning reference signal resource set instance. The length of the second bitmap is equal to the number of uplink positioning reference signal resources in a single uplink positioning reference signal resource set.

In this form, for the second bitmap, if one single repetition index of an uplink positioning reference signal resource in one uplink positioning reference signal resource set instance is muted in the second bitmap, uplink positioning reference signal resources corresponding to the single repetition index in all uplink positioning reference signal resource set instances are muted.

In the above two forms of silence patterns, the N is configurable, and the value of N is selected from the set M: m= {2, 4, 8, 16, 32}.

Step 102, the target uplink positioning reference signal resource or resource set is sent.

In addition, in order to further improve the positioning accuracy of the uplink reference signal and facilitate the terminal to determine what form of silence pattern is adopted, on the basis of the above embodiment, the sending may further include:

the terminal acquires configuration information, wherein the configuration information is used for indicating a silencing scheme used by the terminal. The configuration information may be pre-stored in the terminal, may be agreed with a protocol, or may be sent to the terminal by the network side device.

using only the first silence pattern;

using only the second silence pattern;

the first and second silence patterns are used simultaneously.

If the configuration information indicates that the terminal uses the first silence pattern and the second silence pattern at the same time, the terminal also needs to perform certain operation according to the first silence pattern and the second silence pattern, so as to obtain a final silence pattern. Specifically, the terminal performs a logical AND (AND) operation on each bit in the first bitmap AND all bits in the second bitmap, so as to obtain a final silence pattern. Then, the step 101 specifically includes: and determining the target uplink positioning reference signal resource or resource set according to the final silence pattern.

Referring to fig. 2, fig. 2 is a flowchart of an information processing method provided in an embodiment of the present invention, which is applied to a first network side device, as shown in fig. 2, and includes the following steps:

step 201, receiving a target uplink positioning reference signal resource or a resource set sent by a terminal, where the target uplink positioning reference signal resource or the resource set is configured to be in a sending state.

The target uplink positioning reference signal resource or the resource set is determined by the terminal according to a resource transmission pattern. The resource transmission pattern includes a muting pattern, and the transmission state includes a non-muting state.

In order to further reduce uplink interference between network side devices born by the network side devices when the network side devices receive uplink positioning reference signals sent by the respective terminals, the network side devices can coordinate silence patterns used by the network side devices.

Thus, on the basis of the above embodiment, the method may further include: the first network side device coordinates with the second network side device the muting pattern used. For example, taking a network side device as a base station, the base stations can coordinate the respective silence patterns used between the base stations through an Xn interface between the base stations or through an LMF mode.

Specifically, when the signal quality of the uplink positioning reference signal of the received target terminal is lower than a first preset threshold, or when the signal strength of the uplink positioning reference signal of the received target terminal is lower than a second preset threshold, the first network side device coordinates with the second network side device to use the silence pattern; wherein the target terminal belongs to the second network side device. By adopting the event triggering coordination mode, only the most urgent coordination request can be sent, which is beneficial to the adoption of staggered SRS resources among network side devices and improves the coordination effect of stronger interference.

The quality of the uplink positioning reference signal comprises SINR or RSRQ; the strength of the uplink positioning reference signal comprises RSRP.

Wherein the first network side device may coordinate the silence pattern used with the second network side device in at least one of:

(1) And sending the silence pattern used by the first network side device to the second network side device, and/or receiving the silence pattern used by the second network side device sent by the second network side device.

That is, in this manner, the silence patterns used respectively are interacted between the first network-side device and the second network-side device through the Xn interface.

For example, the base station a transmits the silence pattern a used by itself to the neighboring base station B through the inter-base station Xn interface, and the neighboring base station B of the base station a adopts the silence pattern B orthogonal to or staggered from the silence pattern a as much as possible after receiving the silence pattern a.

(2) And transmitting the silence pattern used by the first network side device to an LMF (local mean square), so that the LMF transmits the silence pattern used by the first network side device to the second network side device, and/or receives the silence pattern used by the second network side device transmitted by the LMF.

That is, in this manner, the first network-side device and the second network-side device interact with each other through the LMF with the silence pattern used.

For example, the base station a and the base station B report the silence pattern a and the silence pattern B used by each to the LMF. After the LMF receives the information, the silence pattern B of the adjacent base station B around the base station A is notified to the base station A, and the silence pattern a of the adjacent base station A around the base station B is notified to the base station B, wherein the silence patterns which are orthogonal or staggered with each other are adopted as far as possible by the base station A and the base station B.

(3) And receiving a silence pattern allocated by the LMF, wherein the LMF allocates the silence pattern to the first network side device from a public silence pattern set.

That is, in this manner, the LMF assigns a muting pattern to each network-side device. The LMF sets a common set of muting patterns, which contains muting patterns for positioning of all terminals, and which are mutually orthogonal or low-correlated. The LMF then assigns different muting patterns to different network side devices that try to use muting patterns that are orthogonal or staggered to each other.

In addition, to further reduce interference, the first network side device may also perform interference cancellation using the muting pattern obtained from the third network side device. The third network side device refers to any network side device, for example, the second network side device may also be used. The interference cancellation method may also be an interference method in the prior art, which is not limited in the embodiment of the present invention.

In the following embodiments, specific implementation procedures of the embodiments of the present invention will be described in detail by taking a resource transmission pattern as a silence pattern and a transmission state as a non-silence state as an example.

Specifically, in the embodiment of the present invention, according to the muting pattern, the terminal determines an uplink positioning reference signal resource or a resource set configured to be in a non-muting state, and sends the uplink positioning reference signal resource or the resource set in the non-muting state.

Correspondingly, on the network side equipment side, the uplink positioning reference signal resource or resource set which is sent by the terminal and is configured into a non-silent state is received. Meanwhile, the silence patterns used by the network side equipment can be coordinated among the network side equipment, and interference elimination is carried out by utilizing the silence patterns obtained from other network side equipment.

Wherein, the silence pattern refers to a bitmap (bitmap) of length N. The muting pattern is applicable to periodic uplink positioning reference signals. The uplink positioning reference signal refers to a sounding reference signal SRS-Pos applied to positioning.

In the embodiment of the invention, the silence pattern comprises the following two implementation schemes:

each bit in the scheme one, bitmap corresponds to at least one consecutive instance of an uplink positioning reference signal resource set (in an uplink positioning reference signal resource set transmitted in one cycle). Once a certain uplink positioning reference signal resource set instance is muted in the bitmap, all uplink positioning reference signal resources in that resource set instance are muted.

And each bit in the bitmap corresponds to a single repeated index of each uplink positioning reference signal resource in an uplink positioning reference signal resource set example, and the length of the bitmap is equal to the number of the uplink positioning reference signal resources in a single uplink positioning reference signal resource set.

The length N of the silence pattern bitmap is configurable, and the value of N is selected from the set M, m= {2, 4, 8, 16, 32}.

In practical applications, the terminal may be configured to employ a combination of the two silence pattern schemes described above in the following form:

(1) Only silence pattern scheme one is used;

(2) Only silence pattern scheme two is used;

(3) While using the silence pattern scheme one and scheme two.

If the above-described manner (3) is adopted, the silent pattern one AND silent pattern two are applied with a logical AND operation, that is, for each bit in the silent pattern scheme one bitmap, all bits in the silent pattern scheme two bitmaps are operated on using a logical AND operation.

Hereinafter, a specific implementation procedure of the embodiment of the present invention will be described in connection with different silence patterns.

In the following embodiments, the terminal is configured to use only the silence pattern scheme one. That is, each bit in the bitmap corresponds to at least one consecutive instance of a set of uplink positioning reference signal resources (set of uplink positioning reference signal resources transmitted in one cycle). Once a certain uplink positioning reference signal resource set instance is muted in the bitmap, all uplink positioning reference signal resources in that resource set instance are muted.

In the embodiment of the present invention, each bit is used to silence the entire set of uplink positioning reference signal resources, and 1 bit may silence multiple consecutive sets of uplink positioning reference signal resources.

The muting refers to that the terminal does not send the uplink positioning reference signal resource or the uplink positioning reference signal resource set.

As shown in fig. 3, the uplink positioning reference signal is SRS, and in the figure, the SRS set transmission time domain position diagram is shown at a subcarrier interval of 120 KHz. The SRS resource set period of the terminal is 80ms and includes 80 subframes in total. With 120KHz, a subframe contains 8 slots, one slot being represented by each small vertical cell. White small bars represent slots that do not contain SRS resources and black small bars represent slots that contain SRS resources. In this embodiment, each SRS resource occupies 12 symbols, so each slot can only accommodate one SRS resource. Each period includes 4 SRS resource sets, 1 SRS resource set includes 4 SRS resources, and SRS resources belonging to the same SRS resource set are represented by the same color.

(1) If each bit in the muting pattern bitmap corresponds to one SRS resource set, 4 bits are needed to be used as the bitmap of the scheme, and each bit in the 4 bits corresponds to one SRS resource set, for example, when the bitmap is 0101, it indicates that SRS resource 1 set and SRS resource 3 set are muted and not transmitted by the terminal. Whereas SRS resource set 2 and SRS resource set 4 are not muted and will be transmitted by the terminal.

(2) If each bit in the muting pattern bitmap corresponds to multiple consecutive SRS resource sets, such as 2 consecutive SRS resource sets for each bit, then 2 bits are needed as a bitmap for the scheme, and each bit in 2 bits corresponds to two SRS resource sets, for example, when the bitmap is 10, it indicates that SRS resource 3 and SRS resource 4 are muted and not transmitted by the terminal. And SRS resource set 1 and SRS resource set 2 are not muted and will be transmitted by the terminal.

Above, bit 0 is used to represent silence in the silence pattern bitmap, bit 1 represents non-silence; of course, bit 1 may also be used to represent silence, with bit 0 representing non-silence.

In the embodiment of the invention, the whole uplink positioning reference signal resource set or a plurality of continuous uplink positioning reference signal resource sets can be silenced by using 1 bit by using the silencing pattern scheme, and the method has the advantage of relatively small signaling overhead.

In the following embodiment, the terminal is configured to use only the silence pattern scheme two. That is, each bit in the bitmap corresponds to a single repetition index of each uplink positioning reference signal resource in an uplink positioning reference signal resource set instance, and the length of the bitmap is equal to the number of uplink positioning reference signal resources in a single uplink positioning reference signal resource set.

In this scheme, each bit is silent single uplink positioning reference signal resource, and is applicable to all uplink positioning reference signal resource set instances to which the uplink positioning reference signal resource belongs. Namely: if the terminal configures a plurality of uplink positioning reference signal resource set instances, uplink positioning reference signal resources corresponding to index numbers in each resource set instance are silenced.

As shown in fig. 4, the uplink positioning reference signal is SRS, and in the figure, the SRS set transmission time domain position diagram is shown at a subcarrier interval of 120 KHz. The SRS resource set period of the terminal is 80ms and includes 80 subframes in total. With 120KHz, a subframe contains 8 slots, one slot being represented by each small vertical cell. White small bars represent slots that do not contain SRS resources and black small bars represent slots that contain SRS resources. In this embodiment, each SRS resource occupies 12 symbols, so each slot can only accommodate one SRS resource. Each period includes 4 SRS resource sets, 1 SRS resource set includes 4 SRS resources, and SRS resources belonging to the same SRS resource set are represented by the same color.

According to the scheme of the muting pattern scheme two, since each bit in the muting pattern bitmap corresponds to one SRS resource in a single SRS resource set, and the single SRS resource set in fig. 4 contains 4 SRS resources, then according to fig. 4, 4 bits are needed to be used as the bitmap of the scheme, and each bit in the 4 bits corresponds to one SRS resource and is an SRS resource corresponding to a corresponding position in the 4 SRS resource set. For example, when the bitmap is 0101, it means that both SRS resource 1 and SRS resource 3 in each of the 4 SRS resource sets are muted and not transmitted by the terminal. Whereas SRS resource 2 and SRS resource 4 are not muted and will be transmitted by the terminal. In this case, a total of 8 SRS resources are muted (4 SRS resource sets×2 SRS resources).

In the embodiment of the invention, the muting pattern scheme can use 1-bit muting uplink positioning reference signal resources with single index number, and has the advantages of being capable of selectively muting the single uplink positioning reference signal resources in the resource set and high in flexibility.

In the following embodiments, the terminal is configured to use the muting pattern scheme one and the muting pattern scheme two. That is, the silence pattern scheme one AND the silence pattern scheme two may be configured AND used simultaneously, AND if both silence pattern schemes are configured, a logical AND (AND) operation is applied, that is, for each bit in the silence pattern scheme one bitmap, all bits of the silence pattern scheme two bitmap are operated on using the logical AND (AND).

As shown in fig. 5, if the bitmap of the muting pattern scheme one is 10 AND the bitmap of the muting pattern scheme two is 0101, both are to apply a logical AND (AND) operation, that is, since the first bit of the muting pattern scheme one corresponds to the SRS resource set 1 AND the SRS resource set 2, AND is 1, AND the illustration is not muted, the SRS resource set 1 AND the SRS resource set 2 can be directly muted using the bitmap 0101 of the muting pattern scheme two, that is, the 1 st SRS resource AND the 3 rd SRS resource of the SRS resource set 1 AND the SRS resource set 2 are muted, AND the 2 nd AND 4 th SRS resources are not muted. And, since the second bit of the muting pattern scheme one is 0, which indicates muting, the 3 rd SRS resource set and the 4 th SRS resource set corresponding to the bit need muting, and all SRS resources in the two resource sets need muting, so that the bitmap of the muting pattern scheme two does not need to be checked.

In the embodiment of the invention, the whole uplink reference signal resource set and the uplink positioning reference signal resource of a single index number can be silenced by using the silencing pattern scheme I and the silencing pattern scheme II at the same time, and the method has the advantages of being capable of silencing the whole resource set and selectively silencing single uplink positioning reference signal resource in the resource set and having highest flexibility.

For the muting pattern described above, coordination can be made between different base stations or cells in several ways. Hereinafter, coordination between two different base stations is described as an example. When coordination is performed between three or more base stations or two or more different cells, the coordination principle is the same.

Coordination mode 1: the muting pattern is coordinated between base stations (no LMF participation): the base station A sends the used silence pattern a to the adjacent base station B through an Xn interface between the base stations, and after receiving the silence pattern a, the adjacent base station B of the base station A adopts a silence pattern B which is orthogonal or staggered with the silence pattern a as much as possible.

Coordination mode 2: the silence pattern is reported to the LMF, coordinated by (LMF participation): the base station A and the base station B report the respectively used silence pattern a and silence pattern B to the LMF, after the LMF receives the silence pattern B of the adjacent base station B around the base station A to the base station A, and also notify the silence pattern a of the adjacent base station A around the base station B to the base station B, wherein the base station A and the base station B adopt the silence patterns orthogonal or staggered with each other as much as possible.

Coordination mode 3: LMF sets a common silence pattern set (LMF control): the LMF sets a common set of muting patterns, which contains muting patterns for positioning of all users, and the muting patterns are mutually orthogonal or low-correlation. The LMF will then assign different muting patterns to different base stations that employ muting patterns that are as orthogonal or staggered to each other as possible.

In the above three coordination schemes, the silence pattern is transmitted between base stations, and can also be used for interference cancellation. For example, after the base station a acquires the muting pattern B of the surrounding base station B through the Xn interface or the LMF, the base station a performs interference cancellation using the muting pattern B of the base station B.

In coordination, event triggered coordination may be employed. For example, when the base station a finds that the quality (e.g. SINR (Signal-to-noiseand interference ratio, signal-to-interference plus noise ratio) or RSRQ (Reference Signal Received Quality )) or strength (e.g. RSRP (Reference Signal Received Power, reference Signal received power)) of the uplink reference Signal received by itself from the UE belonging to the base station B is lower than a certain preset threshold, coordination is performed by using the Xn interface between base stations or LMF.

The above several coordination schemes and specific coordination modes are described below in connection with different embodiments respectively.

In one embodiment of the invention, the muting pattern is coordinated among base stations (without LMF participation): the base station A sends the used silence pattern a to the adjacent base station B through an Xn interface between the base stations, and after receiving the silence pattern a, the adjacent base station B of the base station A adopts a silence pattern B which is orthogonal or staggered with the silence pattern a as much as possible.

As shown in fig. 6, the serving base station of UE1 is gNB1, and UE1 transmits an uplink positioning reference signal SRS, and each of gnbs 1 to gNB5 needs to listen to the SRS in order to complete the positioning calculation. In order to avoid mutual interference caused by collision of SRS sent by UE1 and SRS sent by UE served by gNB 2-gNB 5, gNB1 sends a used muting pattern a to adjacent base stations gNB 2-gNB 5 through an Xn interface between gNB and gNB, and after receiving the muting pattern a sent by gNB1, adjacent base stations gNB 2-gNB 5 adopt muting patterns b, c, d and e which are orthogonal or staggered with the muting pattern a as much as possible, so that when the UE served by gNB 2-gNB 5 sends the SRS, SRS resources different from the SRS resources used by UE1 are adopted, and mutual interference is avoided.

The silence pattern coordinates among the base stations in a mode of an Xn interface among the base stations, so that uplink interference among the base stations born by the base stations when the base stations receive uplink positioning reference signals sent by respective service terminals is avoided or reduced, and the receiving quality and positioning accuracy of the uplink reference signals are improved.

In one embodiment of the invention, the silence pattern is reported to the LMF, coordinated by the LMF (LMF participation): the base station A and the base station B report the respectively used silence pattern a and silence pattern B to the LMF, after the LMF receives the silence pattern B of the adjacent base station B around the base station A to the base station A, and also notify the silence pattern a of the adjacent base station A around the base station B to the base station B, wherein the base station A and the base station B adopt the silence patterns orthogonal or staggered with each other as much as possible.

As shown in fig. 7, the serving base station of UE1 is gNB1, and UE1 transmits an uplink positioning reference signal SRS, and each of gnbs 1 to gNB5 needs to listen to the SRS in order to complete the positioning calculation. In order to avoid mutual interference caused by collision of SRS transmitted by UE1 and SRS transmitted by UEs served by gNB2 to gNB5, gNB1 transmits a muting pattern a used by itself to the location management functional unit LMF, and neighboring base stations gNB2 to gNB5 transmit respective muting patterns b, c, d, e to the location management functional unit LMF. After the LMF receives the silence patterns b, c, d, e of the neighboring base stations gNB2 to gNB5 around the gNB1 are notified to the gNB1, and the silence pattern a of the gNB1 is also notified to the gNB2 to gNB5, and the silence patterns orthogonal to or staggered with each other are adopted as much as possible for the gNB1 and the gNB2 to gNB 5. Thus, when the UEs served by the gnbs 2 to 5 transmit SRS, SRS resources different from those used by the UE1 are adopted, so that mutual interference between the UEs is avoided.

The silence pattern coordinates among the base stations in an LMF mode, so that uplink interference among the base stations born by the base stations when the base stations receive uplink positioning reference signals sent by respective service terminals is avoided or reduced, and the receiving quality and positioning accuracy of the uplink reference signals are improved.

In one embodiment of the invention, the LMF sets a common set of silence patterns (LMF control): the LMF sets a common set of muting patterns, which contains muting patterns for positioning of all users, and the muting patterns are mutually orthogonal or low-correlation. The LMF will then assign different muting patterns to different base stations that employ muting patterns that are as orthogonal or staggered to each other as possible.

As shown in fig. 8, the serving base station of UE1 is gNB1, and UE1 transmits an uplink positioning reference signal SRS, and each of gnbs 1 to gNB5 needs to listen to the SRS in order to complete the positioning calculation. In order to avoid mutual interference caused by collision of SRS transmitted by UE1 and SRS transmitted by UE served by gNB 2-gNB 5, LMF sets a common silent pattern set { a, b, c, d, e }, wherein the common set contains silent patterns for positioning of all users, and the silent patterns are mutually orthogonal or have low correlation. The LMF then assigns different muting patterns to different base stations that try to use muting patterns { a, b, c, d, e } that are orthogonal or staggered to each other. gNB1 employs silence patterns a, gNB2 through gNB5 employ silence patterns b, c, d, e, respectively. Thus, when the UEs served by the gnbs 2 to 5 transmit SRS, SRS resources different from those used by the UE1 are adopted, so that mutual interference between the UEs is avoided.

The silence patterns are distributed to the base stations in an orthogonal or staggered manner by setting up a public resource pool through the LMF, so that uplink interference among the base stations born by the base stations when the base stations receive uplink positioning reference signals sent by respective service terminals is avoided or reduced, and the receiving quality and positioning accuracy of the uplink reference signals are improved.

In the above three coordination schemes, the muting pattern is transmitted between base stations for interference cancellation. For example, after the base station a acquires the muting pattern B of the surrounding base station B through the Xn interface or the LMF, the base station a performs interference cancellation using the muting pattern B of the base station B. As described above, in the case where the SRS resource is relatively tight and cannot be coordinated and staggered, the above three coordination schemes may still not ensure that uplink SRS interference cannot occur between the base stations, and in this case, the silence pattern B of the neighboring base station B acquired through the Xn interface or the LMF is helpful for the base station a to perform interference cancellation, because the interference cancellation effect is better in the case where the interference source and the interference time-frequency location are known.

In the three coordination schemes, the coordination is performed by adopting an event triggering type. For example, when the base station a finds that the quality (for example: SINR or RSRQ) or strength (for example: RSRP) of the uplink reference signal received by itself from the UE belonging to the base station B is lower than a certain preset threshold, coordination is performed by adopting the Xn interface manner or the LMF manner between the base stations.

As described above, the base station a does not always send the silence pattern used by itself to the surrounding neighboring base stations through the Xn interface, or coordinates through the LMF, but adopts time triggered coordination, that is: when the base station A finds that the quality (such as SINR or RSRQ) or strength (such as RSRP) of the uplink reference signal received by itself from the UE belonging to the base station B is lower than a certain preset threshold, the coordination is performed by adopting an Xn interface mode or an LMF mode between the base stations. By doing so, the situation that the neighbor base station cannot stagger SRS resources when the coordination requests are too many can be avoided. Only the most urgent coordination request can be sent, which is beneficial to the neighbor base stations to adopt the staggered SRS resources, and improves the coordination effect of stronger interference.

As can be seen from the above description, in the embodiment of the present invention, an uplink positioning reference signal muting pattern scheme is used, and the muting pattern is coordinated between base stations by means of an Xn interface or LMF between base stations, so that uplink interference between base stations, which is born by the base stations when receiving uplink positioning reference signals sent by respective service terminals, is avoided or reduced, and the reception quality and positioning accuracy of the uplink reference signals are improved.
