Introducing uplink positioning:

the 5G NR introduces a variety of positioning techniques for achieving positioning of a terminal. For the uplink positioning technology and the uplink and downlink hybrid positioning technology, an uplink positioning reference signal sent by a terminal to network equipment is required to be used for positioning the terminal. The uplink positioning reference signal is a sounding reference signal (Sounding Reference Signal, SRS), and the network device needs to configure the uplink positioning reference signal for the terminal first, so as to be able to receive the uplink positioning reference signal sent by the terminal. The network device can configure the uplink positioning reference signal for the terminal by sending the uplink positioning reference signal configuration to the terminal. The uplink positioning reference signal configuration includes time-frequency resources used when the terminal transmits the uplink positioning reference signal.

In the NR of R16 (Release 16), the following method for terminal positioning based on SRS is introduced:

enhanced cell identity (Identity Document, ID) positioning method;

uplink arrival time difference positioning method;

multi-cell round trip time positioning method;

uplink angular of arrival positioning method.

In the above method, an uplink positioning reference signal needs to be used. In R16, when the terminal is located by the above method, the terminal needs to be in a radio resource control (Radio Resource Control, RRC) connected state, which results in a large power consumption overhead of the terminal.

In the NR of R17, positioning of a terminal in an RRC inactive (inactive) state is supported. The terminal may send an uplink positioning reference signal to the network device when in the RRC inactive state. Specifically, when the network device transitions the terminal from the RRC connected state to the RRC inactive state, the network device configures an uplink positioning reference signal for the terminal through an RRC release (release) message. The detailed configuration corresponding to the uplink positioning reference signal is contained in the positioning reference signal radio resource control inactive state configuration (srs-PosRRC-Inactive config) of the RRC release message. And under the condition that the terminal performs cell reselection, the terminal needs to release the uplink positioning reference signal configured by the network equipment, namely release the uplink positioning reference signal configuration. For example, after cell reselection, the terminal deletes the locally stored uplink positioning reference signal configuration.

In NR of R18, there is a need for low power consumption and high accuracy (Low Power High Accuracy, LPHA) positioning, that is, power consumption of terminal positioning needs to be further reduced, and positioning of RRC idle (idle) state terminals may be introduced. For the mode of configuring the uplink positioning reference signals for the terminals in the RRC idle state and the RRC inactive state, if the mechanism of R17 is used, namely the configuration is performed through the RRC release message, the configuration of the uplink positioning reference signals is invalid after the terminal performs cell reselection. In this configuration mode, the terminal needs to reenter RRC connected to acquire the uplink positioning reference signal configuration, which increases power consumption of the terminal and cannot meet the requirement of the LPHA.

Introducing random access of a terminal:

the random access of the terminal can be classified into 2 types including 4-step random access and 2-step random access. The terminal initiates 4-step random access by sending Message 1 (Message 1, msg 1) to the base station. The terminal initiates 2-step random access by sending a Message a (Msg a) to the base station. In the 4-step random access, after sending the Msg 1, the terminal receives the Message 2 (Message 2, msg 2) fed back by the base station, and then the terminal sends the Message 3 (Message 1, msg 3) to the base station, and receives the Message 4 (Message 4, msg 4) fed back by the base station, thereby completing the random access. In the 2-step random access, after sending the Msg a, the terminal receives a Message B (Message B, msg B) fed back by the base station, thereby completing the random access. Wherein, msg a can be regarded as packaging and transmitting uplink Msg 1 and Msg 3, and Msg B can be regarded as packaging and transmitting downlink Msg 2 and Msg 4.

According to the method provided by the embodiment of the application, the terminal is configured with the random access channel (Random Access Channel, RACH) resources for uplink positioning, so that the uplink positioning of the terminal is realized. Compared with the prior art that the terminal needs to reenter the connection state after cell reselection to acquire the uplink positioning reference signal configuration so as to realize uplink positioning, the method provided by the embodiment of the application can avoid the terminal to switch to the connection state to perform uplink positioning under the condition of cell reselection by using the prior random access mechanism to perform uplink positioning of the terminal, thereby reducing the power consumption of the terminal. The method provided by the embodiment of the application also configures the uplink positioning reference signal for the terminal through the system message, and realizes that the uplink positioning of the terminal is performed by configuring the uplink positioning reference signal for the terminal through a broadcasting mechanism of the system message. The uplink positioning can be avoided by switching to the connection state under the condition of cell reselection, and the power consumption of the terminal is reduced.

Fig. 1 is a schematic diagram of a communication system provided in an exemplary embodiment of the present application. The communication system 100 may include: a terminal 101, an access network device 102 and a core network device 103.

The number of terminals 101 is typically a plurality and one or more terminals 101 may be distributed within the cell managed by each access network device 102. The terminal 101 may include various handheld devices, in-vehicle devices, wearable devices, computing devices, or other processing devices connected to a wireless modem, as well as various forms of User Equipment (UE), mobile Station (MS), and the like, having wireless communication capabilities. For convenience of description, in the embodiment of the present application, the above-mentioned devices are collectively referred to as a terminal.

The access network device 102 is a means deployed in the access network to provide wireless communication functionality for the terminal 101. The access network device 102 may include various forms of macro base stations, micro base stations, relay stations, access points. The names of access network device-capable devices may vary in systems employing different radio access technologies, for example in 5G NR systems, called gndeb or gNB. As communication technology evolves, the name "access network device" may change. For convenience of description, in the embodiment of the present application, the above-mentioned devices for providing the wireless communication function for the terminal 101 are collectively referred to as an access network device. A connection may be established between the access network device 102 and the terminal 101 over an air interface, such that communication, including interaction of signaling and data, is performed over the connection. The number of access network devices 102 may be plural, and two adjacent access network devices 102 may also communicate via wired or wireless means. The terminal 101 may switch between different access network devices 102, i.e. establish a connection with different access network devices 102.

The core network device 103 mainly functions to provide user connection, management of users, and bearer completion of traffic, and to provide an interface to an external network as a bearer network. The access network device 102 and the core network device 103 may be collectively referred to as network devices. The core network device 103 and the access network device 102 communicate with each other via some over-the-air technology, and a communication relationship can be established between the terminal 101 and the core network device 103 via the access network device 102.

The "5G NR system" in the embodiments of the present application may also be referred to as a 5G system or an NR system, but a person skilled in the art may understand the meaning thereof. The technical scheme described in the embodiment of the application can be applied to a 5G NR system and also can be applied to a subsequent evolution system of the 5G NR system.

Fig. 2 shows a flowchart of an uplink positioning method according to an embodiment of the present application. The method can be applied to network equipment. The method comprises the following steps:

step 202: and transmitting the RACH resource configuration to the terminal.

The RACH resource is configured to configure a first RACH resource, the first RACH resource is related to uplink positioning of the terminal, and the first RACH resource is used for realizing the uplink positioning of the terminal. The RACH resource configuration may be regarded as a dedicated configuration, i.e. a RACH resource configuration dedicated for uplink positioning. The first RACH resource may be regarded as a dedicated resource, i.e. a RACH resource dedicated for uplink positioning.

The RACH resource configuration is different from the existing RACH resource configuration, which means RACH resource configuration that cannot be realized or is not dedicated for uplink positioning of a terminal. The first RACH resource is different from a second RACH resource, which is an existing RACH resource that cannot be realized or is not dedicated for uplink positioning of a terminal. That is, after the network device receives a random access Preamble (Preamble) sent by the terminal through the first RACH resource, it may determine that the terminal requests uplink positioning reference configuration, or may determine that positioning needs to be performed on the terminal, so as to perform corresponding positioning measurement. And when the network equipment receives the random access preamble sent by the terminal through the second RACH resource, the network equipment considers that the terminal is in a normal random access process. I.e. the network device will not determine that the terminal is requesting the configuration of the uplink positioning reference signal or will not determine that the terminal needs to be positioned.

Optionally, the RACH resource configuration is carried in at least one of the following messages:

system messages (System Information, SI);

RRC message.

Optionally, the network device sends SI to the terminal by broadcasting, so as to send RACH resource configuration to the terminal. The RRC message is, for example, an RRC release message.

Optionally, the RACH resource configuration includes at least one of the following information:

random access occasion (RACH occalation);

random access preamble index (RACH Preamble index).

Wherein, the terminal selects the RACH occipital used by the terminal from one or more RACH occipital, and sends Msg 1 or Msg a to the network device at the selected RACH occipital, thereby initiating random access. The RACH Preamble index is used for the terminal to determine the Preamble it uses.

The terminal can determine the first RACH resource for uplink positioning by receiving the RACH resource configuration, and further can execute the uplink positioning related procedure through the first RACH resource. Optionally, the terminal can request the network device to configure an uplink positioning reference signal for the terminal through the first RACH resource. The network device can also determine the location of the terminal through the first RACH resource, for example from information sent by the terminal through the first RACH resource.

Aiming at the situation that a terminal configures an uplink positioning reference signal through a first RACH resource request:

the terminal sends a configuration request of an uplink positioning reference signal to the network equipment through the first RACH resource, and the network equipment receives the configuration request of the uplink positioning reference signal sent by the terminal through the first RACH resource. The configuration request is used for requesting the network equipment to configure an uplink positioning reference signal for the terminal. Optionally, the terminal requests to the network device to configure an uplink positioning reference signal for the terminal by initiating a random access procedure.

Optionally, the configuration request is carried in at least one of the following messages:

·Msg 1；

·Msg A。

after receiving the configuration request sent by the terminal, the network device sends a response message of random access to the terminal.

In one possible implementation, the reply message carries an uplink positioning reference signal configuration. The terminal can acquire the uplink positioning reference signal configuration configured by the network equipment by receiving the response message, so that the terminal can send the uplink positioning reference signal according to the uplink positioning reference signal configuration, and uplink positioning of the terminal is realized.

Optionally, the response message includes at least one of the following:

·Msg 4；

·Msg B。

in another possible implementation, the reply message carries a positioning reference signal configuration identity. In this case, the network device may also send one or more sets of uplink positioning reference signal configurations to the terminal through the SI. Optionally, the SI is transmitted by broadcasting. Wherein, a set of uplink positioning reference signal configuration corresponds to a positioning reference signal configuration identifier.

The positioning reference signal configuration identifier carried by the response message and the positioning reference signal configuration identifier corresponding to the uplink positioning reference signal configuration are used for determining the uplink positioning reference signal configuration used by the terminal in one or more sets of uplink positioning reference signal configurations. That is, the terminal determines the uplink positioning reference signal configuration used by the terminal in one or more sets of uplink positioning reference signal configurations in the SI according to the positioning reference signal configuration identifier carried by the response message and the positioning reference signal configuration identifier corresponding to the uplink positioning reference signal configuration.

For example, the terminal determines the uplink positioning reference signal configuration corresponding to the positioning reference signal configuration identifier carried by the response message in the SI, that is, the uplink positioning reference signal configuration with the same positioning reference signal configuration identifier as the positioning reference signal configuration identifier carried by the response message in the SI, as the uplink positioning reference signal configuration used by the terminal. In this way, the network device can configure its dedicated uplink positioning reference signal configuration to the terminal, and the terminal can determine the uplink positioning reference signal configuration used by the network device according to the positioning reference signal configuration identifier sent by the network device through the response message.

Optionally, the response message includes at least one of the following:

·Msg 2；

·Msg 4；

·Msg B。

because the Msg 2 is complex, the Msg 2 carries the positioning reference signal configuration identifier, and the Msg 2 does not carry the uplink positioning reference signal configuration, so that the implementation difficulty of the scheme can be simplified, and the modification to the Msg 2 is reduced.

Optionally, the positioning reference signal configuration identifier corresponding to the uplink positioning reference signal configuration and the positioning reference signal configuration identifier carried in the response message are random access preamble identifiers (Random Access Preamble Identifier, rapid).

It should be noted that, if the network device configures the first RACH resource to the terminal through an RRC message (RRC release message), after the terminal sends a configuration request through Msg 1 and the network device sends Msg 2 to the terminal, the random access procedure of the terminal is completed. The reason is that RACH resources configured by the network device to the terminal through the RRC message are terminal-specific, and thus, there is no need for the terminal to perform contention-based random access.

For the case that the network device determines the terminal position through the first RACH resource:

the terminal transmits a random access Preamble (Preamble) to the network device through the first RACH resource, and the network device receives the Preamble transmitted by the terminal through the first RACH resource. The preamble is used for positioning the terminal by the network device. Optionally, the terminal sends the Preamble to the network device through Msg 1 or Msg a based on the first RACH resource.

Optionally, the network device locates the terminal by measuring the Preamble sent by the terminal. For example, the network device locates the terminal by measuring the arrival time of the Preamble.

In summary, in the method provided in this embodiment, the terminal is configured with the first RACH resource related to uplink positioning, so as to perform uplink positioning on the terminal. The method and the device realize uplink positioning of the terminal by using a random access mechanism, and can avoid the situation that the terminal is switched to a connection state to perform uplink positioning under the condition of cell reselection, thereby reducing the power consumption of the terminal.

Fig. 3 shows a flowchart of an uplink positioning method according to an embodiment of the present application. The method can be applied to network equipment. The method comprises the following steps:

step 302: and sending one or more sets of uplink positioning reference signal configurations to the terminal through the SI.

Optionally, the network device sends SI to the terminal in a broadcast manner, so as to send the one or more sets of uplink positioning reference signal configurations to the terminal. After receiving the SI, the terminal can acquire the uplink positioning reference signal configuration configured by the network equipment, so that the uplink positioning reference signal can be sent to the network equipment according to the uplink positioning reference signal configuration, and the uplink positioning of the terminal is realized.

Optionally, the network device further receives a configuration request of an uplink positioning reference signal sent by the terminal through the second RACH resource, and sends a response message of random access to the terminal. The response message carries the positioning reference signal configuration identifier.

The second RACH resource may be regarded as an existing RACH resource, which refers to a RACH resource that cannot be implemented or is not dedicated for uplink positioning of the terminal. The terminal may also directly initiate random access according to the second RACH resource without transmitting a configuration request for the uplink positioning reference signal.

Optionally, the response message includes at least one of the following:

·Msg 2；

·Msg 4；

·Msg B。

optionally, in one or more sets of uplink positioning reference signal configurations sent by the network device to the terminal through the SI, one set of uplink positioning reference signal configuration corresponds to one positioning reference signal configuration identifier. The positioning reference signal configuration identifier carried by the response message and the positioning reference signal configuration identifier corresponding to the uplink positioning reference signal configuration are used for determining the uplink positioning reference signal configuration used by the terminal in one or more sets of uplink positioning reference signal configurations in the SI. That is, the terminal determines the uplink positioning reference signal configuration used by the terminal in one or more sets of uplink positioning reference signal configurations in the SI according to the positioning reference signal configuration identifier carried by the response message and the positioning reference signal configuration identifier corresponding to the uplink positioning reference signal configuration.

Optionally, the positioning reference signal configuration identifier corresponding to the uplink positioning reference signal configuration and the positioning reference signal configuration identifier carried in the response message are rapid.

In summary, in the method provided in this embodiment, the uplink positioning reference signal is configured for the terminal through the system message, so that the uplink positioning of the terminal is performed by configuring the uplink positioning reference signal for the terminal through the broadcast mechanism using the system message. The terminal can be prevented from being switched to the connection state to perform uplink positioning under the condition of cell reselection, and the power consumption of the terminal is reduced.

Fig. 4 shows a flowchart of an uplink positioning method according to an embodiment of the present application. The method can be applied to the terminal. The method comprises the following steps:

step 402: and receiving the RACH resource configuration sent by the network equipment.

The RACH resource configuration is different from the existing RACH resource configuration, which means RACH resource configuration that cannot be realized or is not dedicated for uplink positioning of a terminal. The first RACH resource is different from a second RACH resource, which is an existing RACH resource that cannot be realized or is not dedicated for uplink positioning of a terminal.
