Description

Positioning broadcast configuration method and communication device

Technical Field

The present invention relates to the field of wireless communications, and in particular, to a method for configuring positioning broadcast and a communication device.

Background

In wireless communication technology, a positioning function is one of important functions. The position of the terminal device can be obtained according to the positioning function, so that diversified application scenes, such as emergency rescue positioning, navigation or traffic control, can be constructed.

Positioning functions in wireless communication technology may be implemented by reference signal based positioning technology. The positioning technology based on the reference signal comprises an uplink positioning technology based on the fact that the terminal equipment sends a sounding reference signal (sounding reference signal, SRS).

Currently, the configuration information of the SRS is generated by the access network device, and then the access network device sends the configuration information of the SRS to the terminal device through a radio resource control (radio resource control, RRC) connection. However, with the development of wireless communication technology, the mobile service has more and more requirements for uplink positioning, and how to optimize the configuration flow of the uplink positioning reference signal to save network resources is a problem to be solved at present.

Disclosure of Invention

The configuration method and the communication device for positioning broadcast can optimize the configuration flow of the uplink positioning reference signal so as to save network resources.

In order to achieve the above purpose, the embodiments of the present application adopt the following technical solutions:

in a first aspect, a positioning broadcast configuration method is provided, where the method may be performed by a positioning management network element, or may be performed by a component of the positioning management network element, for example, a processor, a chip, or a chip system of the positioning management network element, or may be implemented by a logic module or software capable of implementing all or part of functions of the positioning management network element. The following description is made by taking this method as an example by the location management network element. The method comprises the following steps: the positioning management network element generates a positioning system information block posSIB and sends a first message to the first access network device. The first message includes a posSIB, where the first message is used to instruct a first access network device to send the posSIB, where the posSIB includes first SRS configuration information corresponding to the first access network device, where the first SRS configuration information includes one or more SRS configuration information in candidate SRS configuration information, where the candidate SRS configuration information includes configuration information of an SRS that each access network device in the at least one access network device desires to receive, and the first access network device is an access network device determined in the at least one access network device.

In this embodiment of the present application, the first SRS configuration information in the posSIB may include SRS configuration information corresponding to a first access network device, or may further include SRS configuration information corresponding to an access network device adjacent to the first access network device. Furthermore, after the first access network device broadcasts the posSIB, the plurality of terminal devices residing in the cell covered by the first access network device may acquire the SRS configuration information of the first access network device without dedicated signaling, or may also acquire the SRS configuration information of the access network device adjacent to the first access network device, which not only saves signaling overhead, but also may enable the plurality of terminal devices to share uplink positioning resources so as to improve the utilization rate of the uplink positioning resources. Therefore, based on the configuration method of the positioning broadcast provided by the embodiment of the application, the configuration flow of the uplink positioning reference signal can be optimized so as to save network resources.

In one possible implementation, the posSIB further includes one or more of the following: the physical cell identity PCI corresponding to the first SRS configuration information, the global cell identity CGI corresponding to the first SRS configuration information, the absolute radio frequency channel number ARFCN corresponding to the first SRS configuration information, the single frequency network SFN initialization time corresponding to the first SRS configuration information, the synchronization signal/physical layer broadcast channel block SSB configuration corresponding to the first SRS configuration information, the spatial direction information corresponding to the first SRS configuration information, the geographic coordinates corresponding to the first SRS configuration information, the transmission reception point transmission timing offset group TRP TEG corresponding to the first SRS configuration information, the TRP type corresponding to the first SRS configuration information, or the TRP beam antenna information corresponding to the first SRS configuration information.

In a possible implementation manner, the method for configuring positioning broadcast provided in the first aspect further includes: the positioning management network element receives candidate SRS configuration information; the positioning management network element determines one or more pieces of SRS configuration information from the candidate SRS configuration information as first SRS configuration information. Accordingly, the positioning management network element receives the candidate SRS configurations. After the positioning management network element receives the candidate SRS configuration, the positioning management network element may trigger the flow of broadcasting the posSIB. That is, at least one access network device may actively trigger a positioning broadcast procedure that broadcasts SRS configuration information.

In one possible implementation, the candidate SRS configuration information includes configuration information for SRS that each of the at least one access network device expects to be received under the at least one cell or at least one frequency point or at least one geographic region.

In a possible implementation manner, before the positioning management network element sends the first message to the first access network device, the positioning broadcast configuration method provided in the first aspect further includes: the positioning management network element sends a second message to the first access network device, wherein the second message carries the first SRS configuration information, and the second message is used for requesting the first access network device to perform resource configuration according to the first SRS configuration information; the positioning management network element receives a third message from the first access network device, wherein the third message is used for indicating the first access network device to support resource configuration according to the first SRS configuration information; or the positioning management network element sends a second message to the first access network device and the access network device adjacent to the first access network device, wherein the second message carries the first SRS configuration information, and the second message is used for requesting the first access network device and the access network device adjacent to the first access network device to perform resource configuration according to the first SRS configuration information; the positioning management network element receives a third message from the first access network device and the access network device adjacent to the first access network device, wherein the third message is used for indicating the first access network device and the access network device adjacent to the first access network device to perform resource configuration according to the first SRS configuration information. That is, it may be determined whether the current first access network device may perform resource configuration according to the first SRS configuration information through the second message and the third message. If the target access network device feeds back that the resource configuration according to the first SRS configuration information cannot be supported currently, the positioning management network element can determine new first SRS configuration information in the candidate SRS configuration information again, and send a second message to the target access network device.

In one possible implementation, the third message includes region information corresponding to the first SRS configuration information. Since the first access network device or the access network device adjacent to the first access network device may change or update the region information corresponding to the configuration information of the SRS that is expected to be received, the positioning management network element may obtain the region information corresponding to the updated first SRS configuration information through the third message.

In a possible implementation manner, before the positioning management network element receives the candidate SRS configuration, the positioning broadcast configuration method provided in the first aspect further includes: the positioning management network element sends a fourth message to the at least one access network device, where the fourth message is used to request configuration information of SRS that each of the at least one access network device expects to receive. Because the positioning management network element can actively send the fourth message to request the candidate SRS configuration information, the positioning management network element can perform positioning broadcast configuration according to the obtained candidate SRS configuration information. That is, the supporting positioning management network element requests candidate SRS configuration information as needed according to positioning requirements, and then performs positioning broadcasting.

In a possible implementation manner, the method for configuring positioning broadcast provided in the first aspect further includes: the positioning management network element receives the region information corresponding to the candidate SRS configuration information.

In one possible implementation, the region information includes one or more of the following: cell information, frequency point information, or geographical area information.

In a possible implementation manner, the cell information includes a cell list corresponding to the first access network device and/or a cell list corresponding to an access network device adjacent to the first access network device.

The method is described below as being performed by the first access network device. The method comprises the following steps: the first access network device receives a first message from the location management network element and sends a posSIB according to the first message. The first message includes a posSIB, where the posSIB includes first SRS configuration information corresponding to a first access network device, where the first SRS configuration information includes one or more SRS configuration information in candidate SRS configuration information, where the candidate SRS configuration information includes configuration information of an SRS that each access network device in the at least one access network device desires to receive, and the first access network device is an access network device determined in the at least one access network device.

Since in the embodiment of the present application, for the first SRS configuration information in the posSIB, the first SRS configuration information may include SRS configuration information corresponding to the first access network device, or may further include SRS configuration information corresponding to access network devices adjacent to the first access network device. Furthermore, after the first access network device broadcasts the posSIB, the plurality of terminal devices residing in the cell covered by the first access network device may acquire the SRS configuration information of the first access network device without dedicated signaling, or may also acquire the SRS configuration information of the access network device adjacent to the first access network device, which not only saves signaling overhead, but also may enable the plurality of terminal devices to share uplink positioning resources so as to improve the utilization rate of the uplink positioning resources. Therefore, based on the configuration method of the positioning broadcast provided by the embodiment of the application, the configuration flow of the uplink positioning reference signal can be optimized so as to save network resources.

In a possible implementation manner, before the first access network device receives the first message from the positioning management network element, the positioning broadcast configuration method provided in the second aspect further includes: the first access network device sends configuration information of the SRS expected to be received by the first access network device to the positioning management network element.

Detailed Description

For the convenience of understanding the technical solutions provided in the embodiments of the present application, a brief description of the related technology of the present application is first given. Briefly described as follows:

first, SRS:

the SRS in the embodiments of the present application may include an uplink reference signal (i.e., MIMO-SRS) for multiple-input multiple-output (MIMO) employed by version15 (version 15, R15) and a version16 (version 16, R16) proposed by an uplink positioning reference signal (positioning sounding reference signal, pos-SRS) dedicated for positioning or other reference signals in the future.

Second, SRS configuration information:

the SRS configuration information is used for the terminal device to transmit SRS. The access network device may send the SRS configuration information to the terminal device through RRC connection. The SRS configuration information may include a manner of transmitting the SRS, time domain resources, frequency domain resources, or the like.

The contents included in the SRS configuration information are described below by taking a New Radio (NR) system as an example.

In the NR system, an SRS resource set (resource set) and SRS resources (resource) are introduced. The SRS configuration information may include one or more SRS resource sets or one or more SRS resources. Wherein one SRS resource set may include one or more SRS resources. An SRS resource may include one or more of the following:

1. number of antenna ports: in an NR system, one SRS resource may configure 1, 2, or 4 antenna ports.

2. Time domain position: in an NR system, the time domain position includes an index, a start position, and the like of an occupied orthogonal frequency division multiplexing (orthogonal frequency division multiplexing, OFDM) symbol. The OFDM symbol index may indicate the number of OFDM symbols occupied by SRS resources, one SRS resource may configure 1, 2, 4, 8 or 12 OFDM symbols, and the starting position may be given by a field startPosition.

3. Resource type: in an NR system, SRS resources can be classified as periodic (periodic), semi-persistent (semi-persistent), or aperiodic (aperiodic). For semi-persistent or periodic SRS resources, a period designated for the terminal device and a slot offset index (slot offset) may be included in one SRS resource.

4. Occupied resource element (RB) index: in an NR system, one SRS resource may occupy 4-272 RBs.

5. Frequency domain comb (comb) configuration: in an NR system, the comb configuration may include an index of the comb structure, wherein the index of the comb structure may have a value of 2 or 4.

It should be noted that, one SRS resource may further include a repetition factor (field repetition factor) of SRS transmission, an offset of the SRS resource in a frequency domain, a frequency modulation configuration of the SRS resource, and so on, and a specific description may refer to a technical standard (technical standard, TS) 38.211 of the third generation partnership project (3rd generation partnership project,3GPP), which is not described herein again.

Thirdly, uplink positioning technology based on SRS:

the principle of the positioning technology based on SRS is to perform positioning by measuring related parameters of SRS sent by the access network equipment receiving terminal equipment. The relevant parameter of SRS may be for example the observed time difference of arrival (observed time difference of arrival, OTDOA) or the angle of arrival (arrival of arrival, AOA). Exemplary, SRS-based positioning techniques may include:

1. uplink time difference of arrival (uplink time difference of arrival, UL-TDOA)

The positioning principle of the UL-TDOA is to measure the arrival time difference of SRS sent by different access network equipment receiving terminal equipment and determine the position information of the terminal equipment according to the arrival time difference.

2. Uplink angle of arrival (uplink angle of arrival, UL-AOA)

The positioning principle of the UL-AOA is to measure the uplink reaching angle of SRS sent by the access network equipment receiving terminal equipment and determine the position information of the terminal equipment according to the uplink reaching angle. The uplink reaching angle may be an included angle between an SRS sent by the terminal device and a certain direction (such as a horizontal plane or a normal line of the horizontal plane) when the SRS reaches the access network device. For example, the uplink arrival angle of the SRS sent by the terminal device may be an angle α between the SRS sent by the terminal device and the north direction when the SRS arrives at the access network device.

Furthermore, SRS-based positioning techniques may also include other positioning techniques, such as Multi-cell round trip time (Multi-cell round trip time, multi-RTT) based positioning techniques or enhanced cell identification (enhanced cell identity, E-CID) based positioning techniques, as embodiments of the present application are not specifically limited.

Fourth, positioning reference signals (positioning reference signal, PRS):

PRS is a downlink positioning reference signal dedicated for positioning proposed by R16. PRS may be applied in positioning techniques such as downlink time difference of arrival (downlink time difference of arrival, DL-TDOA), downlink departure angle (downlink angle of departure, DL-AOD), multi-RTT, or E-CID.

Fifth, positioning system information block (positioning system information block, posSIB):

the posSIB is a system information block (system information block, SIB) proposed by R16 that is dedicated to broadcasting assistance data. The assistance data (assistance data) may provide, among other things, desired characteristics of the global navigation satellite system (global navigation satellite system, GNSS) and/or PRS, such as frequency, desired time of arrival or signal codec information, etc. Further, after the terminal device receives the posSIB, the positioning assistance data carried by the posSIB may be used to acquire and measure GNSS and/or PRS.

In the NR system, the assistance data may be included in a posSIB. Wherein the posSIB may be carried by system information (system information, SI). The mapping of the posSIB to SI message may be configured according to the pos-schedulinglnfolist parameter included in the system information block (system information, SIB) 1. The SIB1 may be periodically broadcast by next-generation radio access network (next-generation radio access network, NG-RAN) devices.

In an NR system, posSIB may be generated and encrypted by a location management function (location management function, LMF).

Alternatively, the LMF may send the posSIB to the NG-RAN device via an NR location protocol a (NR positioning protocol annex, NRPPa) message defined in TS 38.455. The NRPPa message may be an auxiliary information control (assistance information control). The side information control may include a different information element (information element, IE) or group name (group name). Specific IE/group names and attributes corresponding to the IE/group names in the auxiliary control information may be described in table 1.

Fig. 3 is a schematic architecture diagram of a positioning broadcast configuration system according to a positioning broadcast configuration method provided in an embodiment of the present application. As shown in fig. 3, the positioning broadcast configuration system includes a positioning management network element and at least one access network device. Wherein the access network device may support at least one frequency point and may be covered with at least one cell or with at least one geographical area.

The positioning management network element may communicate directly with each of the at least one access network device, or may communicate through forwarding by other devices, which is not specifically limited in this embodiment of the present application. Although not shown, the communication system may further include other network elements or functions or modules such as AMF, which are not specifically limited in the embodiments of the present application.

The following description will take as an example that a positioning management network element interacts with at least one access network device.

In one possible implementation, the positioning management network element generates a posSIB and sends a first message to the first access network device, where the first message includes the posSIB, and the first message is used to instruct the first access network device to send the posSIB. Accordingly, the first access network device receives the first message from the location management network element and sends the posSIB according to the first message. The posSIB comprises first SRS configuration information corresponding to the first access network equipment, and the first SRS configuration information comprises one or more SRS configuration information in candidate SRS configuration information. The candidate SRS configuration information includes configuration information for SRS that each of the at least one access network device expects to receive. The first access network device is an access network device determined by the location management network element in the at least one access network device.

Specific implementations of the above schemes will be described in detail in the following embodiments, which are not described herein.

In this embodiment of the present application, the first SRS configuration information in the posSIB may include configuration information of an SRS that at least one access network device expects to receive, that is, the first SRS configuration may include SRS configuration information corresponding to the first access network device, or may further include SRS configuration information corresponding to an access network device adjacent to the first access network device. Furthermore, after the first access network device broadcasts the posSIB, the plurality of terminal devices residing in the cell covered by the first access network device can acquire the SRS configuration information of the first access network device without dedicated signaling, or can also acquire the SRS configuration information of the access network device adjacent to the first access network device, so that not only signaling overhead can be saved, but also the plurality of terminal devices share uplink positioning resources, and the utilization rate of the uplink positioning network resources can be improved. Therefore, based on the configuration method of the positioning broadcast provided by the embodiment of the application, the configuration flow of the uplink positioning reference signal can be optimized so as to save network resources.

The AAU realizes part of physical layer processing function, radio frequency processing and related functions of the active antenna. Since the information of the RRC layer may eventually become information of the PHY layer or be converted from the information of the PHY layer, under this architecture, higher layer signaling, such as RRC layer signaling, may also be considered to be transmitted by the DU or by the du+aau. It is understood that the access network device may be a device comprising one or more of a CU node, a DU node, an AAU node.

The following will explain a configuration method of positioning broadcast according to an embodiment of the present application with reference to fig. 1 to 6.

It should be noted that, in the embodiments described below, the names of the messages between the network elements or the names of the parameters in the messages are only an example, and may be other names in specific implementations, which are not limited in the embodiments of the present application.

Taking interaction between the location management network element shown in fig. 4 and any access network device as an example, as shown in fig. 7, a configuration method for location broadcast provided in an embodiment of the present application includes the following steps:

s701, the positioning management network element generates a posSIB. The posSIB comprises first SRS configuration information corresponding to the first access network equipment. The first SRS configuration information includes one or more SRS configuration information among the candidate SRS configuration information. The candidate SRS configuration information includes configuration information for SRS that each of the at least one access network device expects to receive.

Wherein the first access network device is an access network device determined in the at least one access network device.

It should be understood that in the embodiment of the present application, the number of access network devices in at least one access network device and the corresponding access network device may be determined by a positioning management network element. For example, the positioning management network element may select a plurality of access network devices that are located adjacent to each other according to registration information (geographical location of the access network device, or cell covered by the access network device, etc.) of each access network device that accesses the core network; for another example, the location management network element selects one or more access network devices with larger coverage area; for another example, the location management network element selects one or two access network devices with a larger number of cells in the coverage area, which is not specifically limited in the embodiments of the present application.

Or, in the embodiment of the present application, the number of access network devices in at least one access network device and the corresponding access network device may be negotiated in advance between the positioning management network element and each access network device in the at least one access network device; or the protocol agrees with the number of access network devices and corresponding access network devices in the at least one access network device, which is not specifically limited in the embodiments of the present application.

It is understood that the at least one access network device may be one or more access network devices. Wherein, for the case that the at least one access network device is only one access network device, the access network device is the first access network device.

It should be noted that, in the case that at least one access network device is a plurality of access network devices, the first access network device may be determined by the positioning management network element; alternatively, the first access network device may be negotiated in advance by the location management network element with one or more of the plurality of access network devices; alternatively, the first access network device may be a protocol agreed, which is not specifically limited in the embodiments of the present application.

Optionally, in the embodiment of the present application, the positioning management network element determines, among the plurality of access network devices, that the first access network device has the following ways:

In a first mode, an access network device with the largest coverage area is selected from a plurality of access network devices as a first access network device. Taking a plurality of access network devices including a macro base station and a plurality of micro base stations as an example, the positioning management network element selects the macro base station as the first access network device.

The manner of determining the first access network device is illustrated by way of example with at least one access network device comprising 4 access network devices. As shown in fig. 8, the at least one access network device includes: access network device #1, access network device #2, access network device #3, and access network device #4. The access network device #4 is a macro base station, and the access network device #1, the access network device #2, and the access network device #3 are micro base stations, and the positioning management network element may determine the access network device #4 as the first access network device.

And selecting the access network equipment with the largest adjacent access network equipment from the access network equipment as first access network equipment.

Illustratively, taking the access network device 4 in fig. 8 as an example, the access network device #1, the access network device #2, and the access network device #3 are access network devices adjacent to the access network device #4, the positioning management network element may determine the access network device #4 as the first access network device. Accordingly, for convenience of presentation, access network device #1, access network device #2, and access network device #3 may be referred to as neighbor access network devices among the at least one access network device.

In the embodiment of the present application, "adjacent" and "neighboring" have the same meaning. In other words, "adjacent" and "neighboring" can be expressed interchangeably, and are described in detail herein, and are not described in detail herein.

In a third mode, the access network device with the largest number of access terminal devices is selected from the plurality of access network devices as the first access network device.

It should be noted that, in the embodiment of the present application, the positioning management network element may also randomly select one access network device from multiple access network devices as the first access network device, and the manner in which the positioning management network element determines the first access network device is not specifically limited in the embodiment of the present application.

It should be understood that in the embodiment of the present application, the positioning management network element may store, in advance, configuration information of an SRS expected to be received by each access network device in at least one access network device; or the positioning management network element and each access network device in at least one access network device negotiate the configuration information of the SRS expected to be received by each access network device in advance; alternatively, the protocol agrees with configuration information of the SRS that each access network device of the at least one access network device desires to receive, which is not specifically limited in the embodiments of the present application.

Alternatively, in one possible implementation, the candidate SRS configuration information may be SRS configuration information that each of the at least one access network device desires to send to the terminal device.

It should be noted that, the configuration information of the SRS that the access network device expects to receive may be SRS configuration information that the access network device may perform resource configuration. Alternatively, the SRS configuration information that the access network device desires to send to the terminal device may be SRS configuration information that the access network device may perform resource configuration.

Optionally, in the embodiment of the present application, the configuration information of the SRS includes one or more SRS configuration information. Wherein, the one SRS configuration information may include one or more SRS resource sets or one or more SRS resources.

It should be noted that, the description of the SRS resource may be referred to in the preamble of the embodiment, and will not be repeated here.

It should be appreciated that in embodiments of the present application, the SRS resource set or SRS resource may be periodic, or semi-persistent, or non-periodic, as embodiments of the present application are not specifically limited thereto.

Optionally, in the embodiment of the present application, the configuration information of the SRS that the access network device expects to receive may include one or more of the following: SRS configuration information corresponding to the number of desired antenna ports, SRS configuration information corresponding to the desired time domain position, SRS configuration information corresponding to the desired resource type, SRS configuration information corresponding to the desired period, SRS configuration information corresponding to the desired frequency domain position, or SRS configuration information corresponding to the desired comb configuration.

As in the embodiments of the present application, the first SRS configuration information includes one or more SRS configuration information among the candidate SRS configuration information. Thus, in case the at least one access network device comprises a plurality of access network devices, the first SRS configuration information may comprise not only SRS configuration information of the first access network device but also SRS configuration information of other access network devices than the first access network device.

Illustratively, taking 4 access network devices as shown in fig. 8 as an example, access network device #1, access network device #2, and access network device #3 are neighboring access network devices, and access network device #4 is a first access network device. The first SRS configuration information may include SRS configuration information corresponding to one or more of the access network device #1, the access network device #2, or the access network device # 3.

Optionally, in the embodiment of the present application, the first SRS configuration information further includes one or more SRS configuration information modified in the candidate SRS configuration information. Since the candidate SRS configuration information may not be desired by the positioning management network element, e.g., the positioning management network element may wish to configure a larger bandwidth resource (e.g., RB) for a certain SRS configuration information in the candidate SRS configuration information, the positioning management network element modifies one or more parameters of the SRS configuration information in the candidate SRS configuration information. Optionally, in an embodiment of the present application, the posSIB further includes network assistance data. Wherein the network assistance data may include one or more of: GNSS public assistance data, GNSS general assistance data, OTDOA assistance data, barometer assistance data, DL-TDOA/DL-AOD assistance data, or PRS assistance data as needed.

Optionally, in an embodiment of the present application, the network assistance data may include first SRS configuration information. Alternatively, the network assistance data comprises assistance data comprising the first SRS configuration information.

It should be noted that, the description of the relevant network assistance data may be referred to in the preamble of the specific embodiment, and will not be repeated here.

Optionally, in an embodiment of the present application, the posSIB further includes one or more of: PCI corresponding to the first SRS configuration information, CGI corresponding to the first SRS configuration information, ARFCN corresponding to the first SRS configuration information, SFN initialization time corresponding to the first SRS configuration information, SSB configuration corresponding to the first SRS configuration information, spatial direction information corresponding to the first SRS configuration information, geographic coordinates corresponding to the first SRS configuration information, TRP TEG association corresponding to the first SRS configuration information, TRP type corresponding to the first SRS configuration information, or TRP beam antenna information corresponding to the first SRS configuration information.

Wherein the TRP type may include one or more of the following: a reception point (SRS-only-rp) that receives only SRS, a reception point (tp), or a transmission reception point (trp).

Alternatively, the PCI corresponding to the first SRS configuration information may include a PCI corresponding to each of the first SRS configuration information. That is, in the case where the first SRS configuration information includes SRS configuration information of other access network devices than the first access network device, the PCI corresponding to the first SRS configuration information may include PCIs corresponding to the first access network device and PCIs corresponding to other access network devices.

Alternatively, the ARFCN corresponding to the first SRS configuration information may include an ARFCN corresponding to each of the first SRS configuration information. The SFN initialization time corresponding to the first SRS configuration information may include an SFN initialization time corresponding to each of the first SRS configuration information. The SSB configuration corresponding to the first SRS configuration information may include an SSB configuration corresponding to each of the first SRS configuration information. The spatial direction information corresponding to the first SRS configuration information may include spatial direction information corresponding to each of the first SRS configuration information. The geographic coordinates corresponding to the first SRS configuration information may include geographic coordinates corresponding to each of the first SRS configuration information. The TRP TEG association corresponding to the first SRS configuration information may include a TRP TEG association corresponding to each SRS configuration information in the first SRS configuration information. The TRP type corresponding to the first SRS configuration information may include a TRP type corresponding to each SRS configuration information in the first SRS configuration information. The TRP beam antenna information corresponding to the first SRS configuration information may include TRP beam antenna information corresponding to each SRS configuration information in the first SRS configuration information.

S702, the positioning management network element sends a first message to the first access network device, wherein the first message comprises a posSIB, and the first message is used for indicating the first access network device to send the posSIB. Accordingly, the first access network device receives a first message from the location management network element.

Accordingly, the first access network device may perform resource configuration according to the first SRS configuration in the posSIB.

Optionally, in an embodiment of the present application, the first message may be an NRPPa message; alternatively, the first message may comprise an NRPPa message. Wherein the NRPPa message may be the side information control described in the preamble of the specific embodiment. The posSIB in the side information control may include first SRS configuration information.

It can be appreciated that the sending of the first message to the first access network device by the positioning management network element in step S702 may refer to steps S101 to S103 in the preamble of the specific embodiment, which are not described herein again.

It should be noted that, in the embodiment of the present application, the positioning management network element may be disposed in an access network device, where the access network device may be one access network device in the at least one access network device, or an access network device other than the at least one access network device, and this embodiment of the present application is not limited in particular.

Optionally, in case the positioning management network element is deployed at the access network device, the positioning management network element may carry the first message through an Xn interface message.

S703, the first access network equipment sends a posSIB according to the first message. Accordingly, the terminal device camping on the cell covered by the first access network device receives the posSIB. That is, the first access network device may broadcast the posSIB to all terminal devices residing within the first access network device coverage cell.

Alternatively, the first access network device may send a broadcast message. Wherein the broadcast message includes a posSIB. The description of the broadcast message may be referred to in the preamble of the specific embodiment, and will not be repeated here.

It should be noted that, in the case that the first SRS configuration information included in the posSIB includes only SRS configuration information corresponding to one access network device, the terminal device may also implement uplink positioning by receiving the first SRS configuration information in the posSIB. Taking UL-AOA as an illustration, the terminal equipment realizes positioning based on one access network equipment, and the UL-AOA positioning technology needs to acquire at least two groups of positioning measurement parameters to realize positioning calculation. In the 5G communication system, the positioning measurement parameters may be multiple groups of positioning measurement parameters obtained by measuring SRS on different beams by the same access network device through SRS sent by different beam receiving terminal devices; it may also be that one access network device measures a plurality of SRS transmitted by the terminal device, so as to obtain at least two sets of positioning measurement parameters. Therefore, the terminal device can realize uplink positioning even if the terminal device receives the SRS configuration information corresponding to only one access network device.

That is, when the terminal device resides in the cell covered by the first access network device, the terminal device does not need to request the SRS configuration information corresponding to the cell by dedicated signaling, but obtains the SRS configuration information corresponding to the cell through the broadcast information (i.e., posSIB) of the first access network device. Furthermore, uplink positioning can be realized according to the SRS configuration information corresponding to the cell. Thus, no special signaling is needed to transmit SRS configuration information between the terminal equipment and the first access network equipment.

Of course, implementing positioning based on UL-AOA may also be using one or a pair of SRS configuration information corresponding to a plurality of access network devices. The method comprises the steps that a plurality of access network devices measure the same SRS sent by terminal devices, and each access network device measures to obtain a group of positioning measurement parameters; or a plurality of access network devices can measure different SRSs sent by the terminal device, and each access network device measures one SRS to obtain a set of positioning measurement parameters.

That is, when the at least one access network device includes two or more access network devices, the first SRS configuration information may include SRS configuration information corresponding to the first access network device and SRS configuration information corresponding to at least one neighboring access network device, so that a terminal device residing in a cell covered by the first access network device may not only obtain SRS configuration information of the first access network device corresponding to the residing cell, but also obtain SRS configuration information corresponding to the neighboring access network device of the residing cell, and further the terminal device may implement uplink positioning through multiple access network devices. Thus, no special signaling is needed to transmit SRS configuration information between the terminal equipment and the first access network equipment, and meanwhile, no special signaling is needed to transmit SRS configuration information between the terminal equipment and the adjacent cell access network equipment.

Optionally, in the embodiment of the present application, the positioning management network element may further send a first message to one or more access network devices within a coverage area of the first access network device, where the first message includes a posSIB, and the first message is used to instruct the one or more access network devices within the coverage area of the first access network device to send the posSIB. Accordingly, one or more access network devices within the coverage area of the first access network device receive the first message and send a posSIB according to the first message.

Illustratively, access network device #4 in fig. 8 is taken as a macro base station, and access network device #1, access network device #2, and access network device #3 are taken as micro base stations as examples. The access network device #4 is a first access network device, where the access network device #1 and the access network device #2 are within a coverage area of the access network device #4, and the positioning management network element may send a first message to the access network device #4, the access network device #1, and the access network device #2 respectively. Accordingly, access network device #4, access network device #1, and access network device #2 broadcast the posSIB, respectively.

That is, a first access network device of the at least one access network device may share the same posSIB with one or more access network devices within the coverage area of the first access network device. In other words, in the embodiment of the present application, multiple access network devices in one area share the same posSIB, and multiple cells covered by the multiple access network devices may share the same uplink positioning resource and/or downlink positioning resource.

Since the at least one access network device may comprise a plurality of access network devices, the positioning management network element may also generate corresponding posSIB for the access network devices other than the first access network device.

Optionally, in an embodiment of the present application, the positioning management network element generates a posSIB corresponding to the second access network device. The second access network device is a different access network device from the first access network device in the at least one access network.

The posSIB corresponding to the second access network equipment comprises second SRS configuration information corresponding to the second access network equipment. The second SRS configuration information includes one or more SRS configuration information among the candidate SRS configuration information.

Alternatively, in the embodiment of the present application, the second SRS configuration information may be the same as or different from the first SRS configuration information.

Illustratively, taking the example that at least one access network device shown in fig. 8 includes 4 access network devices, a scenario in which the second SRS configuration information is the same as the first SRS configuration information is described. As shown in fig. 8, the access network device #4 is a first access network device, and the access network device #3 is a neighbor access network device of the access network device 4. The positioning management network element may select the access network device #3 as the second access network device, and generate a second posSIB for the access network device # 3. It will be appreciated that since the first access network device and the second access network device are adjacent to each other, there is a common neighbor access network device between the cell covered by the first access network device and the cell covered by the second access network device. Thus, the first SRS configuration information corresponding to the first access network device may be the same as the second SRS configuration information corresponding to the second access network device. Alternatively, the posSIB corresponding to the first access network device may be the same as the posSIB corresponding to the second access network device.

By way of example, taking the case where at least one access network device shown in fig. 9 includes 6 access network devices, a scenario in which the second SRS configuration information is different from the second SRS configuration information is described. As shown in fig. 9, the at least one access network device includes: access network device #5, access network device #6, access network device #7, access network device #8, access network device #9, and access network device #10. The adjacent cell access network devices of the access network device #5 are respectively an access network device #6 and an access network device #7, the adjacent cell access network devices of the access network device #10 are respectively an access network device #8 and an access network device #9, and the access network device #6 and the access network device #8 are adjacent to each other. The positioning management network element may determine that the access network device #5 is a first access network device, and the access network device #10 may be a second access network device, where the access network device #5 and the access network device #10 are not adjacent to each other, and a cell covered by the access network device #5 and a cell covered by the access network device #10 have no neighboring access network device in common. The first SRS configuration information corresponding to the first access network device may be different from the second SRS configuration information corresponding to the second access network device. Alternatively, the posSIB corresponding to the first access network device may be different from the posSIB corresponding to the second access network device.

Optionally, as shown in fig. 7, the method for configuring positioning broadcast provided in the embodiment of the present application may further include the following steps:

and S704, the first access network equipment sends auxiliary information feedback to the positioning management network element. Accordingly, the positioning management network element receives the auxiliary information feedback from the first access network device. The auxiliary information feedback may include information that the first access network device transmits a posSIB. The information that the first access network device sends the posSIB may include, for example, but not limited to: whether the first access network equipment transmits a posSIB, information of a cell corresponding to the failure of the first access network equipment to transmit the posSIB, frequency point information corresponding to the failure of the first access network equipment to transmit the posSIB, or information of a geographical area corresponding to the failure of the first access network equipment to transmit the posSIB.

It should be understood that the "auxiliary information feedback" may also be referred to as "auxiliary information response (assistance information response)", and the two meanings are the same, and may be mutually replaced, so that they are collectively described herein, and will not be described in detail.

Optionally, the feedback of the auxiliary information in the embodiment of the present application may be carried through an NRPPa message, and the related description may refer to steps S104 to S105 of the preamble of the specific embodiment, which are not described herein again.

It should be understood that, in the embodiment of the present application, in the case of executing the above-mentioned step S703 and step S704, there is no necessary execution sequence between the step S703 and the step S704, and the step S703 may be executed first and then the step S704 may be executed; step S704 may be executed first, and step S703 may be executed; the above step S703 and step S704 may also be performed simultaneously, which is not particularly limited in the embodiment of the present application.

The actions of the positioning management network element in the steps S701 to S704 may be performed by the processor 601 in the communication apparatus 600 shown in fig. 6 by calling the application program code stored in the memory 602 to instruct the network device, and the actions of the first access network device in the steps S701 to S704 may be performed by the processor 601 in the communication apparatus 600 shown in fig. 6 by calling the application program code stored in the memory 602 to instruct the network device, which is not limited in this embodiment.

Optionally, as shown in fig. 10, in the configuration method of positioning broadcast provided in the embodiment of the present application, before step S701, the method further includes the following steps S705 to S706: s705, the positioning management network element receives candidate SRS configuration information, where the candidate SRS configuration information includes configuration information of an SRS that each access network device in the at least one access network device expects to receive.

Optionally, in the embodiment of the present application, in a case where the positioning management network element is deployed in the 5G core network, the candidate SRS configuration information may be carried by an N2 interface message or an N3 interface message.

Or alternatively, in the embodiment of the present application, in a case where the positioning management network element is deployed in the access network device, the candidate SRS configuration information may be carried by the Xn interface message.

Alternatively, the Xn interface message or the N2 interface message or the N3 interface message may comprise an NRPPa message. The NRPPa message may be an existing NRPPa message or the message may be a new NRPPa message, which is not particularly limited in the embodiments of the present application.

In a possible implementation manner, in an embodiment of the present application, a neighboring access network device of a first access network device in at least one access network device may forward configuration information of an SRS that the access network device expects to receive to the first access network device, and the first access network device may aggregate the configuration information of the SRS that each access network device expects to receive in at least one access network device into candidate SRS configuration information, and send the candidate SRS configuration information to a positioning management network element.

In another possible implementation manner, in the embodiment of the present application, each access network device in at least one access network device sends configuration information of an SRS that each access network device expects to receive to a location management network element, respectively.

Optionally, in an embodiment of the present application, the candidate SRS configuration information includes configuration information of SRS that each of the at least one access network device expects to receive in at least one cell or at least one frequency point or at least one geographical area. Wherein the at least one cell may be at least one cell supported by the access network device. The at least one frequency point may be at least one frequency point supported by the access network device. The at least one geographical area may be at least one geographical area covered by the access network device. The geographic area may be, for example, an industrial park, residential area, commercial area, or the like, to which embodiments of the present application are not specifically limited.

Alternatively, in one possible implementation, the access network device may periodically send configuration information of the SRS that the access network device expects to receive to the positioning management network element. That is, the positioning management network element may periodically obtain SRS configuration information corresponding to the access network device in the candidate SRS configuration.

Or, alternatively, in another possible implementation manner, the access network device may send, to the positioning management network element, configuration information of the SRS that the access network device desires to receive, triggered by an event. Wherein the event may be a request/indication that the access network device receives configuration information that sends to the positioning management network element an SRS that the access network device expects to receive. Alternatively, the event may be another event that causes the access network device to send, to the positioning management network element, configuration information of the SRS that the access network device desires to receive, which is not specifically limited in the embodiment of the present application.

S706, the positioning management network element determines one or more SRS configuration information in the candidate SRS configuration information as first SRS configuration information.

Optionally, in the embodiment of the present application, the first SRS configuration information determined by the positioning management network element in the candidate SRS configuration information may be SRS configuration information that the positioning management network element expects configuration of each access network in the at least one access network device.

Optionally, in the embodiment of the present application, the SRS configuration information that the positioning management network element expects each access network configuration in the at least one access network device may include one or more of the following: SRS configuration information corresponding to the number of desired antenna ports, SRS configuration information corresponding to the desired time domain position, SRS configuration information corresponding to the desired resource type, SRS configuration information corresponding to the desired period, SRS configuration information corresponding to the desired frequency domain position, or SRS configuration information corresponding to the desired comb configuration.

Optionally, in one possible implementation, the first SRS configuration information includes one or more of: SRS configuration information corresponding to a positioning management network element expected cell, SRS configuration information corresponding to a positioning management network element expected frequency point, or SRS configuration information corresponding to a positioning management network element expected geographic region.

The desired cell may be, for example, a cell in which the number of camping terminal devices is greater than or equal to a first threshold. Alternatively, the desired frequency point may be a frequency point where the number of terminal devices accessed is greater than or equal to the second threshold. Alternatively, the desired geographic area can be a geographic area having a number of terminal devices residing within the coverage area greater than or equal to a third threshold. Thus, the first SRS configuration information can be ensured to be shared by a certain number of terminal devices, so that the utilization rate of uplink network resources is improved.

It should be appreciated that the first threshold, the second threshold, or the third threshold may be predefined or agreed upon by a protocol, as embodiments of the present application are not specifically limited thereto. It should be noted that the first threshold value, the second threshold value, and the third threshold value may be equal to or different from each other, which is not specifically limited in the embodiment of the present application.

Optionally, in another possible implementation manner, the positioning management network element selects one or more pieces of SRS configuration information corresponding to the indication information from the candidate SRS configuration information according to the indication information as the first SRS configuration information.

Alternatively, the location management network element may receive indication information from a network element or device or module such as E-SMLC or SLP.

Alternatively, the indication information may include one or more of the following: a specified number of antenna ports, a specified time domain location, a specified resource type, a specified period, a specified frequency domain location, or a specified comb configuration.

In this embodiment of the present application, after the positioning management network element receives the configuration information of the SRS expected to be received from the access network device, the generation of the posSIB may be triggered, and the posSIB is sent to the first access network device. That is, at least one access network device may actively trigger a positioning broadcast procedure that broadcasts SRS configuration information.

Optionally, in an embodiment of the present application, before step S705, the method may include:

and S707, the positioning management network element sends a fourth message to the at least one access network device, where the fourth message is used to request configuration information of SRS that each access network device in the at least one access network device expects to receive. Accordingly, the at least one access network device receives a fourth message from the location management network element. That is, the positioning management network element may actively acquire the candidate SRS configuration information. Furthermore, the positioning management network element may perform a positioning broadcast procedure after acquiring the candidate SRS configuration information.

Alternatively, the fourth message may be an NRPPa message. The NRPPa message may be new; alternatively, the NRPPa message may be existing, such as a TRP information request (TRP information request).

It should be understood that in the case where step S707 is performed previously, the NRPPa message in step S705 may be a TRP information reply (TRP information response).

Optionally, as shown in fig. 10, the method for configuring positioning broadcast provided in the embodiment of the present application may further include the following step S708:

s708, the positioning management network element receives the region information corresponding to the candidate SRS configuration information.

Alternatively, in the embodiment of the present application, the candidate SRS configuration information in step S705 and the region information corresponding to the candidate SRS configuration information in step S708 may be carried in one message.

Optionally, in an embodiment of the present application, the area information includes one or more of the following information: cell information, frequency point information, or geographical area information.

Optionally, in the embodiment of the present application, the cell information includes a cell list corresponding to a first access network device and/or a cell list corresponding to an access network device adjacent to the first access network device.

It should be understood that one cell may correspond to one SRS configuration information; alternatively, one cell may correspond to a plurality of SRS configuration information; alternatively, one SRS configuration information may correspond to a plurality of cells, which is not specifically limited in the embodiments of the present application.

Optionally, in the embodiment of the present application, the frequency point information includes a frequency point list corresponding to a first access network device and/or a frequency point list corresponding to an access network device adjacent to the first access network device.

It should be understood that one frequency point may correspond to one SRS configuration information; or, one frequency point may correspond to a plurality of SRS configuration information; alternatively, one SRS configuration information may correspond to a plurality of frequency points, which is not specifically limited in the embodiments of the present application.

Optionally, in the embodiment of the present application, the geographical area information includes a geographical area list corresponding to the first access network device and/or a geographical area list corresponding to an access network device adjacent to the first access network device.

It should be appreciated that one geographic region may correspond to one SRS configuration information; alternatively, one geographical area may correspond to a plurality of SRS configuration information; alternatively, one SRS configuration information may correspond to a plurality of geographic areas, which is not specifically limited in the embodiments of the present application.

In the embodiment of the application, the positioning management network element can perform positioning broadcast as required by receiving the candidate SRS configuration information or actively sending the request candidate SRS configuration information, so that the positioning management network element can be supported to request the SRS configuration information as required to trigger the configuration flow of the positioning broadcast instead of periodically sending the positioning broadcast under the condition of positioning requirement, and network resources can be saved. In addition, the first SRS configuration information in the posSIB may include configuration information of an SRS that the at least one access network device expects to receive, that is, the first SRS configuration may include SRS configuration information corresponding to the first access network device, or may further include SRS configuration information corresponding to access network devices adjacent to the first access network device. Furthermore, after the first access network device broadcasts the posSIB, the plurality of terminal devices residing in the cell covered by the first access network device can acquire the SRS configuration information of the first access network device without dedicated signaling, or can also acquire the SRS configuration information of the access network device adjacent to the first access network device, so that not only signaling overhead can be saved, but also the plurality of terminal devices share uplink positioning resources, and the utilization rate of the uplink positioning network resources can be improved. In summary, based on the configuration method of positioning broadcast provided by the embodiment of the application, the configuration flow of the uplink positioning reference signal can be optimized to save network resources.

The actions of the positioning management network element in the steps S701 to S708 may be performed by the processor 601 in the communication apparatus 600 shown in fig. 6 by calling the application program code stored in the memory 602 to instruct the network device, and the actions of the first access network device in the steps S701 to S708 may be performed by the processor 601 in the communication apparatus 600 shown in fig. 6 by calling the application program code stored in the memory 602 to instruct the network device, which is not limited in this embodiment.

Optionally, as shown in fig. 11, in the configuration method of positioning broadcast provided in the embodiment of the present application, before step S702, the method further includes the following steps S709 to S711: s709, the positioning management network element sends a second message to the first access network device, wherein the second message carries the first SRS configuration information, and the second message is used for requesting the first access network device to perform resource configuration according to the first SRS configuration information. Accordingly, the first access network device receives a second message from the location management network element.

Alternatively, in the embodiment of the present application, the second message may be an NRPPa message. Wherein the second message may be a new NRPPa message; alternatively, the NRPPa message may be an existing NRPPa message, which is not specifically limited in the embodiment of the present application.

S710, the first access network equipment determines that resource configuration is supported according to the first SRS configuration information.

It should be understood that, after the first access network device determines that resource configuration according to the first SRS configuration information is supported, the first access network may perform resource configuration according to the first SRS configuration information; alternatively, the first access network device does not perform resource configuration according to the first SRS configuration information, but performs resource configuration according to the first SRS configuration information after receiving the posSIB including the first SRS configuration information.

S711, the first access network equipment sends a third message to the positioning management network element, wherein the third message is used for indicating the first access network equipment to support resource configuration according to the first SRS configuration information. Accordingly, after the positioning management network element receives the third message from the first access network device, step S702 is performed. Since the first access network device may be currently in a busy state, configuration information of the SRS expected to be received before may not be configured, it may be determined whether the current first access network device may perform resource configuration according to the first SRS configuration information by sending the third message. If the first access network device feeds back that the resource configuration according to the first SRS configuration information cannot be supported currently, the positioning management network element can determine new first SRS configuration information in the candidate SRS configuration information again, and send a second message to the first access network device. Alternatively, the candidate SRS configuration information received by the positioning management network element is not expected by the positioning management network element, for example, it is desirable to configure a larger bandwidth for a certain SRS configuration information, so the positioning management network element may send second information to the first access network device to determine whether the first access network device supports resource configuration according to the SRS configuration information.

It is understood that the third message may be an NRPPa message. The NRPPa message may be a new message or an existing message, which is not particularly limited in the embodiments of the present application.

Optionally, in the embodiment of the present application, the positioning management network element may further send a second message to at least one access network device adjacent to the first access network device. Accordingly, an access network device adjacent to the first access network device receives the second message from the location management network element. After the access network equipment adjacent to the first access network equipment determines that the resource configuration is supported according to the first SRS configuration information, the access network equipment adjacent to the first access network equipment sends a third message to the positioning management network element. Accordingly, the positioning management network element receives a third message from an access network device adjacent to the first access network device. The third message is used for indicating that the access network equipment adjacent to the first access network equipment supports resource configuration according to the first SRS configuration information.

Optionally, in an embodiment of the present application, the third message includes area information corresponding to the first SRS configuration information. Since the first access network device or the access network device adjacent to the first access network device may change or update the region information corresponding to the configuration information of the SRS that is expected to be received, the positioning management network element may obtain the region information corresponding to the updated first SRS configuration information through the third message.

Optionally, in an embodiment of the present application, the third message may include the first SRS configuration information and region information corresponding to the first SRS configuration information.

Alternatively, in the embodiment of the present application, steps S709 to S711 may be performed before or after step S701, which is not particularly limited in the embodiment of the present application.
