In the technical scheme of the application, the data is collected, transmitted, used and the like, and all meet the requirements of national relevant laws and regulations.
Before describing a method for positioning a 5G cell division base station according to an embodiment of the present application, for convenience of understanding, a technical background of the embodiment of the present application is described in detail first.
Along with the development perfection of Beidou technology, 3GPP R16 starts to introduce a 5G base station positioning function, and active indoor division base stations of current equipment manufacturers already support UTDOA positioning technology, so that the precision reaches the meter level and the method is mainly applied to indoor positioning. However, considering the network deployment cost, the deployment of the active indoor division base station of the actual network 5G is approximately 50% covered by adopting a mode of externally connecting an active indoor division remote radio unit (remote radio unit, RRU) with a passive antenna. For example, as shown in fig. 1, in the actual network 5G indoor positioning networking architecture, in this deployment solution, a baseband processing unit (building base band unit, BBU) sends physical cell identifier (physical cell identifier, PCI) and transmission-reception node (TRP) information of the same RRU to multiple passive antennas, that is, the multiple passive antennas use the same physical cell identifier (physical cell identifier, PCI) and the same transmission-reception node (TRP) information. When the BBU receives the terminal measurement report, the terminal measurement report cannot be determined to be reported through which passive antenna, so that the passive antenna cannot participate in positioning calculation, and the positioning accuracy of a user is reduced, and even the user cannot be positioned. The aggregation unit (HuB) in fig. 1 is a HuB, and the LMF in fig. 1 is a location management function (location management function, LMF).
In order to solve the above problems, the present application provides a method and an apparatus for positioning a 5G indoor division base station, which first generates identification information corresponding to passive antennas by positioning, including virtual PCI information and virtual TRP information, and replaces the configured identification of the first passive antenna with the virtual identification information of the first passive antenna, so that the BBU of the base station can distinguish the passive antennas transmitting terminal measurement reports according to the identification information such as virtual information PCI and virtual TRP information corresponding to each first passive antenna, determine the positions of the passive antennas, and enable the passive antennas to participate in positioning calculation of the base station, thereby improving the positioning accuracy of users.
It can be appreciated that the method for positioning the 5G cell division base station provided by the present application can be performed by a positioning device. The positioning device comprises an information processing module (or simply referred to as a processing module) and an information storage module (or simply referred to as a storage module). The positioning device comprises a BBU of the 5G base station, and the BBU can be added with a processing module and a storage module.
The processing module can be used for distinguishing passive antennas used when the terminal equipment uploads the terminal measurement report by the BBU of the 5G base station, and reporting the terminal measurement report and the identification information of the used passive antennas to the LMF. The storage module can be used for storing the coordinate information of the passive antenna, the corresponding antenna port information, the virtual PCI and the channel delay from the passive antenna to the BBU.
As shown in fig. 2, the method for positioning a 5G indoor division base station according to the present application may include the following steps:
step 101, obtaining identification information of a passive antenna, wherein the identification information of the passive antenna comprises virtual PCI information and virtual TRP information, the virtual PCI information is used for determining cell information of the passive antenna, and the virtual TRP information is used for determining position information of the passive antenna.
In one possible embodiment, step 101 may be performed by the BBU.
In one possible embodiment, the BBU can generate identification information of the passive antennas according to known passive antennas, one for each passive antenna.
Optionally, the identification information includes coordinate information of the passive antenna, antenna port information corresponding to the passive antenna, virtual PCI information of the passive antenna, virtual TRP information of the passive antenna, and channel delay from the passive antenna to the BBU, where the channel delay from the passive antenna to the BBU may be measured or estimated according to a frequency band, a feeder model, and a length used by the passive antenna.
Alternatively, the virtual PCI information may represent an identification of a cell to which the passive antenna corresponds, and the virtual TRP information may represent location information of the passive antenna in the cell.
Alternatively, the identification information may be obtained by an information processing module of the BBU, or may be stored in an information storage module of the BBU. For example, the BBU acquires the longitude coordinate and the latitude coordinate of any passive antenna, generates the coordinate information of the passive antenna according to the longitude coordinate and the latitude coordinate of the passive antenna, and the coordinate information can be generated by the information processing module and stored in the information storage module.
Alternatively, the BBU may divide the passive antennas into passive antenna 1, passive antenna 2, and passive antenna n of … …, and may generate the identification information of passive antenna 1, the identification information of passive antenna 2, and the identification information of passive antenna n of … …, respectively, according to each passive antenna. For example, the BBU may generate virtual PCI information of the passive antenna 1, virtual PCI information of the passive antenna 2, and virtual PCI information of the passive antenna n … … through the information processing module, where n is a natural number, and each virtual PCI information may be in one-to-one correspondence with one passive antenna. The BBU may determine that the receiving terminal measurement information is the passive antenna 1, and may upload the terminal measurement information and virtual PCI information corresponding to the passive antenna 1 to the LMF. For another example, the BBU may further generate virtual TRP information of the passive antenna 1, virtual TRP information of the passive antenna 2, and virtual TRP information of the passive antenna … … n, where n is a natural number, and the BBU may determine that the receiving terminal measures information is the passive antenna 1, and may upload the terminal measured information and the virtual TRP information corresponding to the passive antenna 1 to the LMF. The LMF can determine the passive antenna 1 through identification information such as PCI or TRP of the passive antenna 1.
Alternatively, step 101 may be performed by a BBU in the base station, a memory module in the BBU, or a processing module.
Step 102, determining a first passive antenna according to an antenna port for receiving measurement information of a terminal, wherein the first passive antenna is used for determining identification information of the first passive antenna.
Optionally, prior to step 102, the BBU may obtain a configuration identification of the passive antenna. The configuration information can be generated by the BBU on the passive antenna connected with one RRU, and the same configuration identifier is generated on a plurality of passive antennas corresponding to each RRU, wherein the configuration identifier comprises PCI information, TRP information or channel delay information of the passive antennas. The configuration identifier may be an identifier of a passive antenna generated by the BBU, or may be a configured antenna identifier obtained by the BBU. For example, as shown in fig. 1, before the BBU generates the identification information of the passive antenna through the information processing module, the BBU generates the same PCI information according to the passive antennas, and each passive antenna corresponds to one RRU, so each passive antenna has the same PCI information.
Alternatively, the BBU may determine that the passive antenna that receives the information is the first passive antenna when the information is measured by the receiving terminal. For example, the BBU may determine the PCI of passive antenna 1, the PCI of passive antenna 2, … …, or the PCI of passive antenna n before obtaining the terminal measurement information, where the PCI of passive antenna 1, the PCI of passive antenna 2, and the PCI of … … passive antenna n are all the same. For convenience of distinction, the passive antenna 1 is hereinafter used as a passive antenna for receiving measurement information of a terminal, and the passive antenna 1 is used as a first passive antenna, which may also be referred to as a serving antenna. It will be appreciated that the first passive antenna may also be the passive antenna 2, … … passive antenna n.
Alternatively, the BBU may obtain the first passive antenna, and may determine the identification information of the first passive antenna. The BBU may replace the obtained configuration identification of the first passive antenna with virtual identification information of the first passive antenna. For example, the BBU may obtain PCI information for passive antenna 1, passive antenna 2, … …, and passive antenna n as the same PCI. The BBU replaces the PCIs of passive antenna 1, passive antenna 2 … … passive antenna n with PCIs of passive antenna 1, passive antenna 2, and … … passive antenna n, respectively, wherein PCIs 1, PCI2, … … PCIn are all virtual PCI information. Therefore, in the subsequent step, the location resolving unit (such as LMF) may determine a specific passive antenna for receiving the measurement information of the terminal according to the received PCIs 1, 2, … … PCIn, thereby improving the location accuracy of the base station. Similarly, the BBU may also replace the TRP information of the passive antenna with virtual TRP information, and send the virtual TRP information of the passive antenna to the LMF, so that the LMF determines the specific passive antenna that receives the terminal measurement information.
Alternatively, the terminal may transmit terminal measurement information in the uplink direction, which includes a terminal positioning reference signal (UE-LMF sounding reference signal, UL-SRS).
Alternatively, the BBU may receive UL-SRS signals through the passive antenna 1, which are used to estimate uplink channel quality over a wider bandwidth. The BBU may determine that the antenna port receiving the signal corresponds to the antenna port of the passive antenna 1, and may use the passive antenna 1 as the first passive antenna.
Alternatively, the BBU may replace the PCI of the passive antenna 1 with the virtual PCI information of the passive antenna 1, so that the PCI information of the passive antenna 1 after replacement corresponds to the passive antenna 1 one by one.
Optionally, after determining the first passive antenna, the BBU may acquire the identification information of the first passive antenna as a channel delay from the passive antenna to the BBU. The time of the BBU and the passive antenna are not synchronous because the BBU can have a difference between the channel delay of the passive antenna acquired by the BBU and the channel delay stored by the BBU. The BBU can replace the channel delay of the passive antenna according to the generated or stored virtual channel delay of the passive antenna, thereby correcting the channel delay of the passive antenna. For example, the BBU may generate a virtual channel delay corresponding to the passive antenna 1, where the virtual channel delay reflects channel delay data corresponding to the passive antenna 1. And the BBU receives the terminal measurement information according to the passive antenna 1, takes the moment of receiving the terminal measurement information as the current moment, and acquires the channel time delay of the current moment of the passive antenna 1. The BBU may replace the virtual channel delay of the passive antenna 1 generated by the BBU with the channel delay of the passive antenna 1.
Alternatively, the BBU may use virtual PCI information or virtual TRP information of the first passive antenna as identification information of the first passive antenna. The base station can correct the terminal measurement information according to the virtual channel time delay from the first passive antenna to the base station, and the corrected terminal measurement information is determined.
Alternatively, step 102 may be performed by a BBU in the base station, a memory module in the BBU, or a processing module.
Step 103, transmitting the identification information of the first passive antenna and corrected terminal measurement information, wherein the corrected terminal measurement information is determined according to the identification information of the first passive antenna.
Alternatively, the base station may transmit the identification information of the first passive antenna and the corrected terminal measurement information. For example, the BBU may send the identification information of the passive antenna 1 and the corrected terminal measurement information to the LMF.
Optionally, the following describes a base station positioning procedure related to the present application, taking a 5G-UTDOA positioning request procedure as an example. As shown in fig. 3. The specific steps of the flow are as follows:
step 101 corresponds to step 1, step 102 corresponds to steps 2 to 8, and step 103 corresponds to steps 9 to 10.
Step 1: identification information of the passive antenna is generated. The identification information of the passive antenna comprises coordinate information of the passive antenna, corresponding antenna port information, virtual PCI and virtual TRP, and channel delay from the passive antenna to the BBU. The virtual PCI is only used as a positioning resolving identifier and does not participate in air interface resource allocation; the channel delay from the passive antenna to the BBU can be measured or estimated based on the frequency band, feeder type and length of the passive antenna usage.
Optionally, step 101 corresponds to step 1.
Step 2: the LPP capability transfer process requests the positioning capability of the terminal;
step 3: the LMF transmits an NRPPa location information request (POSITIONING INFORMATION REQUEST) message to a serving gcb (next generation NodeB, i.e., 5G base station, including the BBU/TRP of the present application) to request UL-SRS configuration information of the terminal;
step 4: the serving gNB receives the NRPPa positioning information request (POSITIONING INFORMATION REQUEST) message, determines SRS resources and configures UL-SRS resources for the terminal;
step 5: the serving gNB sends an NRPPa location information response (POSITIONING INFORMATION RESPONSE) message including the UL-SRS resource information to the LMF;
step 6a: the LMF sends an NRPPa location activation request message (POSITIONING ACTIVATION REQUEST) to the serving gNB to request UE SRS signal activation;
step 6b: the terminal carries out UL-SRS transmission according to configuration and sends UL-SRS signals;
step 6c: the serving gNB activates UL-SRS transmission and sends an NRPPa location activation response message (POSITIONING ACTIVATION RESPONSE) to the LMF;
step 7: the LMF sends NRPPa measurement request information (NRPPa MEASUREMENT REQUEST) to the related gNB/TRP to trigger the related gNB/TRP to execute UL-SRS measurement, wherein UL-SRS is terminal measurement information;
step 8: each gNB/TRP judges the passive antenna source (UL-SRS Measurements) of the terminal measurement information according to the antenna port of the passive antenna connection. The base station obtains PCI and TRP of the passive antenna for receiving the terminal measurement information, replaces the PCI and TRP of the passive antenna by virtual PCI and virtual TRP in the identification information of the passive antenna, and corrects the UL-TROA information measured by the antenna according to the channel time delay from the passive antenna to the BBU in the passive antenna information, wherein the UL-TROA is the terminal measurement information. Each gNB/TRP can replace the PCI and TRP of the passive antenna through the information processing module, and the virtual PCI and virtual TRP of the replaced passive antenna can be sent to the LMF.
Steps 2 to 8 correspond to step 102 of the present application.
Step 9: each gNB/TRP transmits an NRPPa MEASUREMENT response message (MEASUREMENT) containing the corresponding UL-SRS MEASUREMENT to the LMF;
step 10: after the positioning is finished, the LMF sends an NRPPa positioning stop message (POSITIONING DEACTIVATION) to the serving gcb to end the measurement reporting.
Steps 9 to 10 correspond to step 103 of the present application.
