And the aforementioned storage medium includes: various media capable of storing program codes, such as a U disk, a removable hard disk, a ROM, a RAM, a magnetic disk, or an optical disk.

The method of the embodiment of the present invention is further described below with reference to an interaction process between a terminal and a network device.

The first embodiment is as follows: the base station determines to configure the positioning reference signal;

as shown in fig. 11, the specific process may include:

step 111: after a positioning server (such as an LMF entity) determines a positioning method, a positioning reference signal configuration request is initiated to a base station where target UE is located, and the base station is requested to configure a positioning reference transmitting signal for the target UE.

For example: the location server determines a plurality of terminals (e.g., UE1, UE2, etc.) participating in inter-terminal positioning, and determines base stations (e.g., a base station gNB1 where UE1 is located and a base station gNB2 where UE2 is located) where the terminals participate in inter-terminal positioning, the location server may initiate a location reference signal configuration request to the base station where the terminal is located, for example, an LMF initiates a location reference signal configuration request to gNB1 to request the gNB1 to configure a location reference transmission signal for the UE 1.

The base station (such as the gNB1) determines the parameter configuration of the positioning reference signal, including any or a combination of the following parameters:

the power, frequency point, bandwidth, activation time, carrier aggregation frequency point, the symbol start position and the symbol length occupied by the positioning reference signal, the symbol start position and the symbol end position occupied by the positioning reference signal, the transmission direction of the positioning reference signal, the antenna mapping relation of the positioning reference signal transmission, and the like. The positioning reference signal may be a periodic signal or a semi-persistent signal.

Step 112; and the base station sends the parameter configuration of the positioning reference signal to the target UE.

For example: the gNB1 determines the parameter configuration of the positioning reference signal and sends the parameter configuration to the UE1, that is, the gNB1 configures the UE1 to send the positioning reference signal 1.

And step 113: and the base station returns the parameter configuration information of the positioning reference signal to the LMF.

For example: the gNB1 determines a parameter configuration configuring positioning reference signal 1 for the UE1 and sends the parameter configuration to the LMF.

Step 114: and the LMF sends the parameter configuration of the positioning reference signal to the other UEs participating in positioning as the received signal configuration of the UEs participating in positioning.

For example: the LMF sends the parameter configuration of the positioning reference signal 1 to the UE2 participating in positioning as the received signal configuration of the UE2, that is, for the UE2 to receive the positioning reference signal 1 transmitted by the UE 1.

Accordingly, a specific procedure for the gNB2 to decide to configure the positioning reference signal for the UE2 may include:

step 115: the LMF initiates a positioning reference signal configuration request to the gNB2 to request the gNB2 to configure a positioning reference transmit signal for the UE 2.

The gNB2 determines a parameter configuration of the positioning reference signal, including any or a combination of the following:

the power, frequency point, bandwidth, activation time, carrier aggregation frequency point, symbol start position and symbol length occupied by the positioning reference signal, symbol start position and symbol end position occupied by the positioning reference signal, positioning reference signal transmitting direction, antenna mapping relation of positioning reference signal transmission and the like. The positioning reference signal may be a periodic signal or a semi-persistent signal.

Step 116: the gNB2 determines the parameter configuration of the positioning reference signal and sends the parameter configuration to the UE2, that is, the gNB2 configures the UE2 to send the positioning reference signal 2.

Step 117: the gNB2 determines a parameter configuration configuring positioning reference signal 2 for the UE2 and sends the parameter configuration to the LMF.

Step 118: the LMF sends the parameter configuration of the positioning reference signal 2 to the UE1 as a received signal configuration of the UE1, that is, for the UE1 to receive the positioning reference signal 2 transmitted by the UE 2.

Example two: the base station determines to configure a positioning reference signal;

step 111': after the positioning server determines the positioning method, a positioning reference signal configuration request is initiated to a base station where the target UE is located, and the base station is requested to configure a positioning reference transmitting signal for the target UE.

Step 112': and the base station sends the parameter configuration of the positioning reference signal to the target UE.

For example: the base station gsb 1 where the UE1 is located determines the parameter configuration of the positioning reference signal, and sends the parameter configuration to the UE1, that is, the gsb 1 configures the UE1 to send the positioning reference signal 1.

Step 113': and the base station sends the parameter configuration of the positioning reference signal to the receiving UE and returns the parameter configuration information of the positioning reference signal to the LMF.

For example: the positioning server initiates a positioning reference signal configuration request to a base station gNB1 where the UE1 is located, requests the gNB1 to configure a positioning reference transmission signal for the UE1, and under the condition that the UE2 (i.e., receiving UE) participating in positioning is located in the base station gNB1, the base station gNB1 may also send the parameter configuration of the positioning reference signal 1 to the UE2, as the received signal configuration of the UE 2.

Step 114': and the base station (such as the gNB1) sends the parameter configuration of the positioning reference signal to the neighboring base station where the receiving UE is located, and returns the parameter configuration of the positioning reference signal to the LMF. And the neighbor cell base station sends the parameter configuration of the positioning reference signal to other UE participating in positioning as the received signal configuration of the UE participating in positioning.

Example three: the LMF determines positioning reference signal configuration;

as shown in fig. 12, the specific process may include:

step 121: after the positioning server (such as an LMF entity) determines the positioning method, the positioning server configures the UE1 with the transmitted positioning reference signal 1, and if the positioning server determines the parameter configuration of the positioning reference signal 1 and sends the parameter configuration to the UE1, the UE is used as the transmitted configuration of the positioning reference signal. Wherein, the parameter configuration comprises any parameter or combination of the following parameters:

Step 122: similarly, the positioning server configures the UE2 to transmit the positioning reference signal 2, e.g., the positioning server determines the parameter configuration of the positioning reference signal 2 and sends it to the UE2 as the transmission configuration of the positioning reference signal. Wherein, the parameter configuration comprises any parameter or combination of the following parameters:

Step 123: the LMF sends the parameter configuration of the positioning reference signal 1 configured for the UE1 to the UE2 participating in positioning as the received signal configuration of the UE2 participating in positioning, that is, the LMF configures the UE2 with the received positioning reference signal 1.

Step 124: the LMF sends the parameter configuration of the positioning reference signal number 2 configured for the UE2 to the UE1 participating in positioning as the received signal configuration of the UE1 participating in positioning, that is, the LMF configures the UE1 to receive the positioning reference signal number 2.

Example four: the LMF determines to apply for transmitting positioning reference signal configuration, and the base station determines to be paired UE to transmit positioning reference signal configuration;

as shown in fig. 13, the specific process includes:

step 131: after the positioning server (such as an LMF entity) determines the relative positioning method, the positioning server configures the UE1 with the transmitted positioning reference signal 1, and for example, the positioning server determines the parameter configuration of the positioning reference signal 1 and sends the parameter configuration to the UE1, which is used as the transmission configuration of the positioning reference signal. Wherein, the parameter configuration comprises any parameter or combination of the following parameters:

Step 132: the LMF sends the parameter configuration of the positioning reference signal 1 configured for the UE1 to the UE2 participating in positioning as the received signal configuration of the UE2 participating in positioning, that is, the LMF configures the UE2 with the received positioning reference signal 1.

Step 133: the positioning server initiates a positioning reference signal configuration request to the base station (e.g., the gNB2) where the UE2 is located, requesting the base station to configure the UE2 for transmitting positioning reference signal 2.

The base station gNB2 determines the parameter configuration of the positioning reference signal 2, including any or a combination of the following:

Step 134: the base station gNB2 sends the parameter configuration of the positioning reference signal 2 to the UE 2.

Step 135: the base station gNB2 returns the parameter configuration of the positioning reference signal 2 to the LMF.

Step 136: the LMF sends the parameter configuration of the positioning reference signal 2 configured for the UE2 by the base station gNB2 where the UE2 is located to the UE1 initiating the positioning request, as the received signal configuration of the UE1, for the UE1 to receive the positioning reference signal 2.

In the above scheme, the network participates in configuring the positioning reference signal, the LMF or the base station completes the positioning reference signal configuration, and the LMF completes the coordination of the reference signal configuration between the terminals. The method ensures that all terminals participating in positioning uniformly complete the transmission and reception of positioning signals under the coordination of the LMF, thereby realizing the support of the relative positioning of the terminals in the cellular network, reducing the interference among the terminals through the resource allocation of the network, completing the resource coordination of all the terminals by means of the network element of the core network, and ensuring the coordination of the positioning reference signal transmission and the reference signal reception of the terminals.
