In the above process, the first cell may determine the aperiodic trigger information of the first DL-PRS of the first cell by itself; or the first cell may obtain the aperiodic trigger information of the first DL-PRS of the first cell through the LMF. The specific method used to obtain the aperiodic trigger information of the first DL-PRS depends on the trigger scheme of the aperiodic DL-PRS.

As shown in Figure 5, if the triggering scheme is gNB-based (based on base station), then the serving cell of UE1 or serving base station gNB1 autonomously determines the aperiodic trigger information of the first DL-PRS; if the triggering scheme is network-based (based on Network side), then, the LMF or LMC determines the aperiodic trigger information of the first DL-PRS, and then sends the aperiodic trigger information of the first DL-PRS to the serving cell of UE1 or the serving base station gNB1.

If the first cell itself determines the aperiodic trigger information of the first DL-PRS of the first cell, since the participation of the LMF is not required, the solution is simple and the time delay is low. In the method for the first cell to obtain the aperiodic trigger information of the first DL-PRS of the first cell through the LMF, the configuration and trigger timing of the DL-PRS can be determined by the LMF. Therefore, under the coordination of the LMF, the serving cell and the Collision between DL-PRS of neighboring cells.

Referring to FIG. 6, FIG. 6 is a schematic diagram of a method for acquiring DL-PRS aperiodic trigger information of a neighboring cell according to an embodiment of the present disclosure. In the embodiment shown in FIG. 6, the serving cell obtains the aperiodic trigger information of the second DL-PRS through the Xn interface between base stations or the LMF.

The first cell (that is, the serving cell) obtains the aperiodic trigger information of the second downlink positioning reference signal (DL-PRS) of the second cell (that is, the neighboring cell, which is not co-located with the first cell), and then the first cell transfers the second The aperiodic trigger information of DL-PRS is sent to the UE.

In the above process, the first cell can obtain the aperiodic trigger information of the second DL-PRS of the second cell through the Xn interface between base stations; or the first cell can obtain the aperiodic trigger information of the second DL-PRS of the second cell through the LMF information. Which method is used to obtain the aperiodic trigger information of the second DL-PRS depends on the trigger scheme of the aperiodic DL-PRS.

As shown in Figure 6, if the trigger scheme is gNB-based, then the serving cell of UE1 or the serving base station gNB1 obtains the aperiodic trigger information of the second DL-PRS of gNB2 through the Xn interface; if the trigger scheme is network-based, then , LMF or LMC determines the aperiodic trigger information of the second DL-PRS, or LMF or LMC obtains the aperiodic trigger information of the second DL-PRS from gNB2, and then sends the aperiodic trigger information of the second DL-PRS to UE1 Serving cell or serving base station gNB1.

If the first cell obtains the aperiodic trigger information of the second DL-PRS of the second cell through the Xn interface, since the participation of the LMF is not required, the solution is simple and the delay is low. In the method in which the first cell obtains the second DL-PRS aperiodic trigger information of the second cell through the LMF, the configuration and trigger timing of the DL-PRS can be determined by the LMF. Therefore, under the coordination of the LMF, the serving cell and the Collision between DL-PRS of neighboring cells.

Referring to FIG. 7, FIG. 7 is a schematic diagram of a serving cell sending the aperiodic trigger information of the DL-PRS of the serving cell to the UE through DCI according to an embodiment of the present disclosure. In the embodiment shown in FIG. 7, the serving cell sends the aperiodic trigger information of the DL-PRS of the serving cell to the UE through DCI.

The serving cell (or serving base station) sends the aperiodic trigger information of the first DL-PRS of the first cell (serving cell) to the UE through DCI.

The aperiodic trigger information of the first DL-PRS includes trigger timing information of the first DL-PRS and/or first DL-PRS configuration information.

The trigger timing information of the first DL-PRS includes aperiodic trigger offset information, and its specific meaning refers to the time slot containing "the DCI that triggers the first DL-PRS resource set" and the "send the first DL-PRS resource set" The offset between the time slots. At this time, each "aperiodic trigger offset information" corresponds to a DL-PRS resource set. Or, the specific meaning refers to the offset between the time slot that contains "the DCI that triggers the first DL-PRS resource set" and the time slot that "sends the first DL-PRS resource". At this time, each "aperiodic trigger offset information" corresponds to a DL-PRS resource.

After receiving the DCI, the UE can receive the first DL-PRS of the first cell in the designated time slot according to the "aperiodic trigger offset information".

A DL-PRS resource set is a collection of several DL-PRS resources. A DL-PRS resource can occupy up to 12 OFDM (Orthogonal frequency division multiplex) symbols. A DL-PRS resource set can be used at most. Configure 64 DL-PRS resources.

As shown in Figure 7, the serving cell or serving base station gNB1 issues the aperiodic trigger information of the first DL-PRS through DCI. This information includes two types of information, one of which is the trigger timing information of the first DL-PRS, namely : In which time slot the UE should receive the first DL-PRS. This information is notified to the UE in the form of "aperiodic trigger offset information". The other type is the first DL-PRS configuration information. Among them, the offset information has two possible configurations:

Offset configuration method 1: Each DL-PRS resource set will be configured with different offset information. "Aperiodic trigger offset information" refers to the offset between the time slot containing "DCI triggering the first DL-PRS resource set" and the time slot "transmitting the first DL-PRS resource set". Therefore, the DL-PRS resource set needs to be sent or received in the time slot indicated by the offset information, that is, the DL-PRS resource set can only be configured in one time slot. If the DL-PRS resource set occupies a lot of time domain resources, it can be configured according to the following method 2.

Offset configuration method 2: Each DL-PRS resource will be configured with different offset information. "Aperiodic trigger offset information" refers to the offset between the time slot containing "DCI triggering the first DL-PRS resource set" and the time slot "transmitting the first DL-PRS resource". In this case, the DL-PRS resource set does not need to be transmitted or received in the time slot indicated by the offset information, but only a single DL-PRS resource is required to be transmitted or received in one time slot. Considering that a single DL-PRS resource occupies at most 12 symbols, this indication method can be applied to various situations.

After receiving the DCI, the UE receives the first DL-PRS of the first cell in the designated time slot according to the "aperiodic trigger offset information". If the above-mentioned offset configuration method 1 is adopted, the UE can complete the reception of the first DL-PRS in one time slot. If the above-mentioned offset configuration method 2 is adopted, the UE may need to complete the reception of all DL-PRS resources included in the first DL-PRS in multiple time slots.

In this embodiment, there are two offset configuration modes. For mode 1, since only the slot offset of the DL-PRS resource set needs to be indicated, the required DCI signaling overhead is relatively small. As for method 2, since the slot offset can be indicated for each DL-PRS resource, the DL-PRS resource configuration is more flexible and can be configured in multiple slots.

Referring to FIG. 8, FIG. 8 is a schematic diagram of a serving cell sending the aperiodic trigger information of the DL-PRS of a neighboring cell to the UE through DCI according to an embodiment of the present disclosure. In the embodiment shown in FIG. 8, the serving cell sends the aperiodic trigger information of the second DL-PRS of the second cell to the UE through DCI.

The serving cell sends the aperiodic trigger information of the second DL-PRS of the second cell (neighboring cell) to the UE through the DCI.

The aperiodic trigger information of the second DL-PRS includes trigger timing information of the second DL-PRS and/or second DL-PRS configuration information.

The trigger timing information of the second DL-PRS is "aperiodic trigger offset information", and its specific meaning refers to the time slot containing "the DCI that triggers the second DL-PRS resource set" and the "send the second DL-PRS resource" Set" the offset between time slots. At this time, each "aperiodic trigger offset information" corresponds to a DL-PRS resource set. Or, the specific meaning refers to the offset between the time slot that contains "the DCI that triggers the second DL-PRS resource set" and the time slot that "sends the second DL-PRS resource". At this time, each "aperiodic trigger offset information" corresponds to a DL-PRS resource.

After receiving the DCI, the UE can receive the second DL-PRS of the second cell in the designated time slot according to the "aperiodic trigger offset information".

As shown in Figure 8, the serving cell or serving base station gNB1 issues aperiodic trigger information of the second DL-PRS through DCI. This information includes two types of information, one of which is the trigger timing information of the second DL-PRS, namely : In which time slot the UE should receive the second DL-PRS. This information is notified to the UE in the form of "aperiodic trigger offset information". The other type is the first DL-PRS configuration information. Among them, the offset information has two possible configurations:

Offset configuration method 1: Each DL-PRS resource set will be configured with different offset information. "Aperiodic trigger offset information" refers to the offset between the time slot containing "DCI triggering the second DL-PRS resource set" and the time slot "transmitting the second DL-PRS resource set". The DL-PRS resource set needs to be sent or received in the time slot indicated by the offset information, that is, the DL-PRS resource set can only be configured in one time slot. For the case where the DL-PRS resource set occupies a lot of time domain resources, it can be configured according to the following method 2.

Offset configuration method 2: Each DL-PRS resource will be configured with different offset information. "Aperiodic trigger offset information" refers to the offset between the time slot containing "DCI for triggering the second DL-PRS resource set" and the time slot for "transmitting the second DL-PRS resource". In this way, the DL-PRS resource set is not required to complete transmission or reception in the time slot indicated by the offset information, but only a single DL-PRS resource is required to complete transmission or reception in one time slot. Consider Up to a single DL-PRS resource occupies 12 symbols at most, and this indication method can be applied to various situations.

After receiving the DCI, the UE receives the second DL-PRS of the second cell in the designated time slot according to the "aperiodic trigger offset information". If the above-mentioned offset configuration method 1 is adopted, the UE can complete the reception of the second DL-PRS in one time slot. If the above-mentioned offset configuration method 2 is adopted, the UE may need to complete the reception of all DL-PRS resources included in the second DL-PRS in multiple time slots.

In the embodiment of the present disclosure, the first information is indicated by improving the DCI. Among them, the DL-PRS request field in the DCI is used to indicate and trigger the configuration status of the first DL-PRS or the second DL-PRS, and each codepoint in the DL-PRS request field is used to trigger one of the DLs -PRS configuration status. The configuration state of the DL-PRS is configured by high-level signaling, and includes at least one piece of configuration information among the DL-PRS resource set list information, the DL-PRS resource set information, and the DL-PRS resource information.

In the embodiments of the present disclosure, the DL-PRS request field can be designed in the following ways:

DL-PRS request field design method 1 (mixed configuration): DCI includes a DL-PRS request field, the number of bits occupied is {0,1,...,N}, where N is a positive integer greater than or equal to 1. The DL-PRS request field indicates the triggered first DL-PRS or second DL-PRS.

DL-PRS request field design method 2 (independently configured in two subfields of a field): DCI includes a DL-PRS request field, which includes two subfields: subfield 1 and subfield 2:

The number of bits occupied by subfield 1 is {0,1,...,Ns}, where Ns is a positive integer greater than or equal to 1. The DL-PRS request field indicates the first DL-PRS triggered.

The number of bits occupied by subfield 2 is {0,1,...,Nn}, where Nn is a positive integer greater than or equal to 1. The DL-PRS request field indicates the second DL-PRS that can be triggered.

DL-PRS request field design method three (independently configured in two fields): DCI includes two independent fields used to trigger aperiodic DL-PRS, namely the DL-PRS request-1 field and the DL-PRS request- 2 fields:

The number of bits occupied by DL-PRS request-1 is {0,1,...,Ns}, where Ns is a positive integer greater than or equal to 1. The DL-PRS request field indicates the first DL-PRS triggered.

The number of bits occupied by DL-PRS request-2 is {0,1,...,Nn}, where Nn is a positive integer greater than or equal to 1. The DL-PRS request field indicates the second DL-PRS that can be triggered.

Figure 9(a) shows the first design method of the DL-PRS request field. This is a hybrid configuration scheme, that is, the configuration of the first DL-PRS and the second DL-PRS are put together in a DL-PRS Request field. Each code point in the DL-PRS Request field may indicate a certain configuration of the first DL-PRS or a certain configuration of the second DL-PRS.

Figure 9(b) shows the second design method of the DL-PRS request field. This is a solution that is independently configured in two subfields of a field, that is, the first DL-PRS and the second DL-PRS are independently configured in two different subfields in a DL-PRS Request field . Each code point in subfield 1 of the DL-PRS Request field indicates a certain configuration of the first DL-PRS, and each code point in subfield 2 indicates a certain configuration of the second DL-PRS, and the first DL -Although both the PRS and the second DL-PRS are placed in the same DL-PRS Request field, they are independently configured in different subfields.

Figure 9(c) shows the third design method of the DL-PRS request field. This is a solution that is independently configured in two fields, that is, the first DL-PRS and the second DL-PRS are independently configured in the DL-PRS Request-1 field and the DL-PRS Request-2. Each code point in the DL-PRS Request-1 field indicates a certain configuration of the first DL-PRS, and each code point in the DL-PRS Request-1 field indicates a certain configuration of the second DL-PRS. The first DL-PRS and the second DL-PRS are separately configured in different DL-PRS Request fields.

The first DL-PRS request field design method allows the first DL-PRS and the second DL-PRS to share one DL-PRS request field, and the signaling overhead is small. DL-PRS request field design method 2 or method 3 can independently configure the first DL-PRS and the second DL-PRS through subfields or fields, and the length of the fields occupied by the first DL-PRS and the second DL-PRS can be Adjustable, flexible configuration.

In the embodiment of the present disclosure, when the first cell (serving cell) sends the aperiodic trigger information of the first DL-PRS of the first cell (serving cell) to the UE through DCI, or sends the second cell (neighboring cell) of the second cell 2. In the case of aperiodic trigger information of DL-PRS, the aperiodic trigger information refers to "aperiodic trigger offset information", and its specific meaning refers to the time slot containing "the DCI that triggers the first DL-PRS resource set" and " The offset between the time slots in which the first DL-PRS resource set is sent. At this time, each "aperiodic trigger offset information" corresponds to a DL-PRS resource set. Or, the specific meaning refers to the offset between the time slot that contains "the DCI that triggers the first DL-PRS resource set" and the time slot that "sends the first DL-PRS resource". At this time, each "aperiodic trigger offset information" corresponds to a DL-PRS resource.

For periodic DL-PRS, the moment of its appearance is fixed, and the UE will be notified in advance through RRC signaling, so the UE only needs to receive the DL-PRS at the moment when the periodic DL-PRS appears. However, for aperiodic DL-PRS, the time of its occurrence is not fixed, so the base station needs to notify the UE of the specific receiving time of the aperiodic DL-PRS through DCI, so that the UE can know when to receive the aperiodic DL-PRS.

In the embodiments of the present disclosure, aperiodic trigger information refers to "aperiodic trigger offset information", which is actually a kind of slot offset, which is used by the base station to trigger aperiodic DL-PRS The offset X (X=nm) between the slot number m (Slot number m) of the DCI and the slot number n (Slot number n) of the actual transmission of aperiodic DL-PRS, because the terminal knows that the base station is used to trigger The slot number m of the DCI of the aperiodic DL-PRS, so after being notified of the offset X, the slot number n (n=m+X) for actually transmitting the aperiodic DL-PRS can be calculated.

In addition, it should be pointed out that the time slot offset in the embodiment of the present disclosure can be configured for each aperiodic DL-PRS resource set with a different time slot offset, or for each aperiodic DL-PRS resource. Configure different time slot offsets. Different time slot offsets are configured for each resource set, and all aperiodic DL-PRS resources triggered this time can only be sent in one time slot. Different time slot offsets are configured for each resource, and all aperiodic DL-PRS resources triggered this time can be sent in different time slots.

Configuring different time slot offsets for each resource set will save signaling overhead. All aperiodic DL-PRS resources triggered this time can only be sent in one time slot. Different time slot offsets are configured for each resource, and the indication is more flexible. All aperiodic DL-PRS resources triggered this time can be sent in different time slots.
