Technical field

This application relates to the field of communication technology, in particular to information processing methods, communication equipment and storage media.

Background technique

This method uses multiple network equipment to measure the uplink reference signal (for example, the preamble) sent by the terminal.

It should be noted that with the continuous evolution of the communication system, the names of the aforementioned network elements may change in other systems that may appear in the future. In this case, the solutions provided in the embodiments of the present application are also applicable.

For ease of description, the following briefly describes the LPP positioning protocol.

In the Third Generation Partnership Project Long Term Evolution (3GPP-LTE) system, an LTE positioning protocol is also defined: Lightweight Presentation Protocol (LPP).

As a general positioning communication protocol, the LPP positioning protocol mainly functions to exchange positioning assistance data and positioning information between network devices and terminals. In fact, it can be used in both the control plane and the data plane. Relatively speaking, the implementation of the control plane requires dedicated control channels and will significantly increase the cost of the mobile network, because multiple network elements need to be upgraded in software and hardware to support these positioning-related control plane signaling. Therefore, the implementation of the user plane is easier to be used in commercial applications

In addition, in some LTE communication systems, the LPP positioning protocol already supports satellite positioning technology, Observed Time Difference of Arrival (OTDOA) positioning technology, and enhanced Cell identity (E-CID) ) Positioning technology, UTDOA-based positioning technology, WiFi-based positioning technology, sensor-based positioning technology, Bluetooth-based positioning technology, TBS-based positioning technology, and their hybrid positioning technology.

Figure 3 shows the main flow chart of uplink positioning based on the preamble signal. As shown in Figure 3, it includes the following steps:

Step1: First, the UE is in an idle or inactive state.

Step2: Under competitive access, the UE selects its own preamble index on a certain time-frequency resource in the Random Access Channel (RACH) and sends it to multiple BSs.

In other words, multiple UEs may select the same preamble signal index and transmit on the same time-frequency resource. Exemplarily, take two UEs as an example, denoted as UE1 and UE2, respectively. The preamble index selected by UE1 is preamble1. Assume that preamble1 is sent to BS1 and BS2 on time-frequency resource 1; the preamble index selected by UE2 is also preamble1. Suppose that preamble1 is sent to BS1 and BS2 on time-frequency resource 1.

Step3: Multiple BSs obtain the uplink received time of arrival (Received Time of Arrival, RTOA) according to the received preamble signal.

That is, BS1 and BS2 obtain the RTOA of UE1 and UE2 based on preamble1 measurement.

Setp4: Multiple BSs report the RTOA to a location management device (Location Management Function, LMF), and the LMF completes positioning based on the reported RTOA.

However, for BS1 and BS2, it is impossible to determine whether preamble1 belongs to UE1 or UE2. Therefore, for LMF, effective positioning cannot be achieved based on the received RTOA.

In response to the foregoing problems, an embodiment of the present application provides an information processing method: a terminal device generates instruction information, and the instruction information includes first configuration information; the terminal device sends first configuration information to a network device, and the first configuration information is used to instruct the terminal device The identification of the terminal equipment is allocated by the core network side. The terminal device sends an uplink reference signal to the network device. The network device receives the first configuration information and the uplink reference signal from the terminal device, the uplink reference signal is used for the network device to generate positioning information; the positioning information is associated with the first configuration information; the network device sends the positioning information and the first configuration information to the positioning device. The following is a detailed description in conjunction with the legend.

Fig. 4 shows a schematic diagram of the interaction flow of an information processing method provided by the present application. As shown in Figure 4, the method may include the following steps:

In step 401, the positioning device sends first configuration information to the terminal device. The terminal device generates instruction information, and the instruction information includes first configuration information; the first configuration information is used to indicate the identity of the terminal device.

In step 402, the terminal device sends the first configuration information and the uplink reference signal through the message MsgA. The network device receives the first configuration information and the uplink reference signal from the terminal device. The first configuration information is used to indicate the identity of the terminal device; the uplink reference signal is used for the network device to generate positioning information; the positioning information is associated with the first configuration information.

Optionally, the uplink reference signal includes a preamble signal.

Specifically, the terminal device reports the first configuration information by means of MsgA, including but not limited to one or more of the following methods:

The first configuration information is carried in the MAC layer; or,

The first configuration information is explicitly reported on the physical layer; or,

The first configuration information is reported implicitly at the physical layer.

In a possible implementation manner, the first configuration information is carried in the MAC layer. Exemplarily, the first configuration information is carried in the MAC layer, and the network device directly receives the first configuration information, and reports the received first configuration information together with the positioning information to the positioning device.

In another possible implementation manner, the first configuration information is explicitly reported on the physical layer. Exemplarily, the first configuration information is used as an additional parameter, the terminal device reports to the network device, and the network device reports the first configuration information and positioning information to the positioning device.

In another possible implementation manner, the first configuration information is reported implicitly at the physical layer. Exemplarily, the first configuration information is included in a random access RNTI (Random Access RNTI, RA-RNTI) parameter. In LTE, the expression of RA-RNTI is:

RA-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id

Among them, s_id is the index of the OFDM symbol in the RACH;

t_id is the index of slot (time slot);

f_id is the index of the subcarrier in the frequency domain;

ul_carrier_id indicates the uplink carrier (0 indicates NUL (normal uplink) carrier, 1 indicates SUL (supplementary uplink) carrier).

It can be seen that the value of RA-CNTI is determined by the position of the time-frequency resource sent by the preamble signal. On the basis of these coefficients, the first configuration information RACH-ID is added, such as:

RA-RNTI=1+s_id+14×t_id+14×80×f_id+14×80×8×ul_carrier_id+14×80×8×2×rach_id

In this way, the network device can calculate the value of the RACH-ID through RA-RNTI, and then report it to the positioning device together with the positioning information.

In another possible implementation manner, the first configuration information is reported implicitly at the physical layer. Exemplarily, the first configuration information is related to the preamble signal index. The original index is randomly selected by the terminal device itself. Here, the terminal device associates the first configuration information with the preamble signal index based on its own first configuration information. The network device detects the preamble signal index through blind detection, and obtains the association relationship between the index and the first configuration information by looking up the table. Furthermore, the first configuration information is calculated, and then reported to the network device together with the positioning information.

In step 403, the network device sends the positioning information and the first configuration information to the positioning device. The positioning device receives the positioning information and the first configuration information sent by the network device.

As an example and not limitation, in steps 401 to 403, the UE is a terminal device, the BS is a network device, the LMF is a positioning device, RACH-ID is the first configuration information sent by the LMF to the BS, and the preamble signal is sent by the UE to the BS. For the uplink reference signal, RTOA is the positioning information generated by the BS. The specific implementation of step 401 to step 403 is illustrated below through step 410 to step 430.

Step 410 includes: when the UE is in the connected state, the LMF configures the RACH-ID for the UE through the LPP protocol layer. Taking two UEs as an example (denoted as UE1 and UE2 respectively), LMF sends RACH-ID1 to UE1, and LMF sends RACH-ID2 to UE2. UE1 and UE2 generate indication information, and the indication information includes RACH-ID1 and RACH-ID2.

Step 420 includes, when the UE is in an idle or inactive state, the UE sends a RACH-ID and a preamble signal through a message MsgA. BS1 and BS2 respectively receive RACH-ID and preamble signal from UE, RACH-ID is used to indicate the identity of said UE; preamble signal is used for BS1 and BS2 to generate RTOA; RTOA is associated with RACH-ID.

Optionally, the manner of reporting the RACH-ID through MSgA has been described in detail in step 402 of the foregoing embodiment, and will not be repeated here.

Step 430 includes that the BS reports the RTOA and RACH-ID to the LMF through the new air interface positioning protocol A (NR Positioning Protocol A, NRPPa); the RACH-ID and the preamble signal received by the BS from the UE are carried in the message MsgA. LMF receives RTOA and RACH-ID1 sent by BS1, LMF receives RTOA and RACH-ID2 sent by BS2, LMF distinguishes UE1 and UE2 according to RACH-ID1 and RACH-ID2, thereby realizing effective positioning.

Optionally, the uplink reference signal includes a preamble signal.

In step 503, the terminal device receives confirmation information RAR from the network device. The network device sends a confirmation message RAR to the terminal device.

In step 504, the terminal device sends the first configuration information through the message Msg3. The network device receives the first configuration information from the terminal device.

For the uplink reference signal, RTOA is the positioning information generated by the BS. The specific implementation manners of step 501 to step 505 are illustrated below through step 510 to step 550.

Step 510 includes: when the UE is in the connected state, the LMF configures the RACH-ID for the UE through the LPP protocol layer. Taking two UEs as an example (denoted as UE1 and UE2 respectively), LMF sends RACH-ID1 to UE1, and LMF sends RACH-ID2 to UE2. UE1 and UE2 generate indication information, the indication information includes RACH-ID1 and RACH-ID2; UE1 sends RACH-ID1 to BS1 and BS2 respectively, UE2 sends RACH-ID2 to BS1 and BS2 respectively, RACH-ID is used to indicate the identity of the UE; The identity of the UE is allocated by the core network side.
