[0020] FIG. 1 shows a block diagram of a wireless communication system applicable to the embodiment of the present application. The wireless communication system includes a terminal 11 and a network device 12. Here, the terminal 11 may be called a terminal device or a user terminal (User Equipment, UE), and may be a terminal side device such as a mobile phone, a tablet computer (Tablet Personal Computer), a laptop computer (also called a notebook computer), a personal digital assistant (PDA), a personal digital assistant, a netbook, an ultra-mobile personal computer (UMPC), a mobile Internet device (Mobile Internet Device, MID), a wearable device (Wearable Device) or a vehicle-mounted device (VUE), a pedestrian terminal (PUE), etc., and the wearable device includes a bracelet, an earphone, glasses, etc. It should be noted that the specific type of the terminal 11 is not limited in the embodiment of the present application.

In the embodiments of the present application, only a base station in an NR system is taken as an example, but it should be noted that the specific type of the base station is not limited.The core network device may be referred to as a Location Management Function (LMF), an Enhanced Serving Mobile Location Center (E-SMLC), a location server, or some other suitable terminology in the art.

[0021] For ease of understanding, some contents related to the embodiments of the present application will be described below.

[0022] First, the state of a terminal includes three states, namely, an idle state, an inactive state, and a connected state. Among them, the connected state may be referred to as a Radio Resource Control connected (RRC_connected) state.

[0023] A UE in the Idle state has no RRC context in the network equipment, i.e., the parameters required for communication between the network equipment and the UE do not belong to a specific cell, and the network equipment does not know whether the UE exists or not. The UE is assigned a set of tracking area identifiers (TAI list). From the perspective of the core network, the connection between the Radio Access Network (RAN) side and the core network is disconnected. To reduce power consumption, the UE is in a sleep state most of the time, so data transmission is not possible. In the downlink, a UE in the Idle state can periodically wake up to receive paging messages from the network equipment. Mobility can be handled by the UE performing cell reselection. In the Idle state, the UE does not maintain uplink synchronization with the network equipment, and to transition from the Idle state to the Connected state, an RRC context must be established between the UE and the network equipment through Random Access.

[0024] In the RRC_Connected state, an RRC context can be established and all parameters required for communication are known to the two entities (UE and network equipment). From the perspective of the core network, the UE is in the CN_Connected state. The UE knows the cell to which it belongs and the device identifier for signaling transmission between the device and the network, i.e. the Cell Radio Network Temporary Identifier (C-RNTI), is configured. In the connected state, mobility can be controlled by the network equipment, i.e. the UE provides neighbor cell measurements to the network equipment and the network equipment commands the terminal to handover. Uplink time synchronization may or may not be present and can be established by random access when data is to be transmitted.

[0025] In the RRC_INACTIVE state, the network device and the UE's RRC context are maintained. From the perspective of the core network, the RAN side and the core network are in a connected state. Therefore, the transition speed from the inactive state to the connected state is very fast and does not require core network signaling. At the same time, the UE is allowed to sleep in a manner similar to the idle state and handle mobility by cell re-election. Therefore, RRC_INACTIVE may be considered as a mixture of the idle and connected states.

[0026] Therefore, the key difference between the different states is the mobility mechanism involved. Efficient mobility handling is a key part of any mobile communication system. For the idle and inactive states, mobility is handled by the terminal performing cell reselection, whereas for the connected state, mobility is handled by the network equipment based on UE measurements.

[0027] The UE returns to the RRC connected state in five cases: when attempting to transmit data on the uplink, when a signaling procedure is initiated at the Non-Access Stratum (NAS) layer, when responding to RAN paging, when notifying the network equipment that it has left the RAN notification area, and when the periodic access network notification area update timer expires.

[0028] 2. Power control and spatial relationship of uplink positioning reference signal in connected state.

[0029] The uplink positioning reference signal may be a sounding reference signal (SRS), in which the time domain type of the uplink positioning reference signal includes periodic, aperiodic and semi-persistent. Optionally, the first configuration information may be configured for each SRS resource set, that is, it may be understood as configuration for each SRS resource set, and the first configuration information may be configured for each SRS resource.

[0030] The path loss reference signal is used to obtain a path loss estimate for the SRS, and includes the synchronization signal block (SSB) of the serving cell, the SSB of a neighboring cell, downlink signals such as CSI-RS, downlink positioning reference signal (PRS), or other SRS.

[0031] Third, random access procedure.

[0032] The 4-step random access may be referred to as a 4-step random access channel (RACH), and more specifically, A contention-based random access procedure, and It includes a non-contention based random access procedure.

[0033] In the "contention-based random access procedure", the UE sends message 1 (Msg1) to the network equipment. After receiving Msg1, the network equipment sends message Msg2 carrying uplink grant information to the UE. The UE sends Msg3 according to the uplink grant information in Msg2. After receiving Msg3, the network equipment sends Msg4 (e.g., a contention resolution identifier) ​​to the UE. The UE receives Msg4 and determines whether the contention resolution is successful. If it is successful, the random access procedure is successful. If not, the random access procedure is restarted.

[0034] In the "non-contention based random access procedure", the network equipment allocates a dedicated RACH resource to the UE for access, the UE sends Msg1 (random access request) to the network equipment on the dedicated resource, and the network equipment sends Msg2 message to the UE after receiving Msg1. However, when the dedicated RACH resource is insufficient, the network equipment instructs the UE to start a contention based random access (Random Access, RA).

[0035] The 2 step RACH includes the following steps: 1. The network device configures new two-step random access configuration information in the UE, for example including transmission resource information corresponding to MsgA and MsgB. 2. The UE triggers a 2-step RACH procedure by sending request information (MsgA) to the network equipment, for example, by transmitting via a Physical Uplink Shared Channel (PUSCH). At the same time, the UE may also send Physical Random Access Channel (PRACH) information to the network equipment. 3. The network device sends confirmation information (MsgB) to the UE. If the UE fails to receive MsgB, it resends MsgA.

[0036] 4. Uplink positioning procedure.

[0037] The uplink positioning procedure includes the following steps. 1. The Location Management Function (LMF) and the TRP exchange location information. 2. The LMF and UE exchange capability information. 3. Request positioning using New Radio Positioning Protocol A (NRPPa). 4. The base station determines the uplink (UL) SRS arrangement. 5. NRPPa positioning response. 6. NRPPa positioning activation request, SRS transmission activation by base station, NRPPa positioning activation response. 7, NRPPa measurement request. 8. The base station performs UL SRS measurement. 9, NRPPa measurement response.

[0038] Hereinafter, an uplink positioning processing method provided in an embodiment of the present application will be described in detail with reference to the drawings according to a specific embodiment and an application case thereof.

[0039] Please refer to FIG. 2, which is a flowchart of an uplink positioning processing method provided in an embodiment of the present application. The method is performed by a terminal. As shown in FIG. 2, Step 201: a terminal receives first configuration information sent by a network device; Step 202, in which the terminal determines target information of a first positioning reference signal according to the first configuration information; The first configuration information includes at least one of power configuration information and spatial relationship configuration information, and when the first configuration information includes the power configuration information, the target information includes a transmission power, and when the first configuration information includes spatial relationship configuration information, the target information includes a spatial relationship, and the first positioning reference signal is for the terminal to perform uplink positioning in an idle state or an inactive state.

[0040] In the embodiments of the present application, the first positioning reference signal may be understood as an uplink positioning reference signal, and specifically may include a preamble, an SRS, or other reference signals for newly defined uplink positioning, and the following embodiments may be described taking SRS as an example.

[0041] It should be understood that the power configuration information and the spatial relationship configuration information may be carried in the same command or the same message, or may be carried in different commands or different messages, and this is not limited thereto. It should be further understood that the first configuration information may carry other information than the power configuration information and the spatial relationship configuration information. Since the target information of the first positioning reference signal is determined by the first configuration information, when the terminal is in an idle state or an inactive state, the first positioning reference signal can be transmitted according to the target information, and uplink positioning in the terminal's idle state or inactive state can be realized.

[0042] It should be noted that the terminal may determine the target information when in a connected state, or may determine the target information when in an idle state or an inactive state, without further limitation thereto.

[0043] It should be noted that the terminal may receive the first configuration information when in a connected state, or may receive the first configuration information when in an idle state or an inactive state.

[0044] In an embodiment of the present application, a terminal receives first configuration information transmitted by a network device, and the terminal determines target information of a first positioning reference signal according to the first configuration information, the first configuration information includes at least one of power configuration information and spatial relationship configuration information, and when the first configuration information includes the power configuration information, the target information includes transmission power, and when the first configuration information includes spatial relationship configuration information, the target information includes spatial relationship, and the first positioning reference signal is for the terminal to perform uplink positioning in an idle state or an inactive state. In this way, when the terminal is in an idle state or an inactive state, the uplink positioning reference signal can be transmitted based on the determined target information, thereby avoiding the terminal transitioning to a connected state to transmit a positioning reference signal. Therefore, the embodiment of the present application reduces the power consumption and delay caused by the terminal's positioning.

[0045] Optionally, in some embodiments, the first configuration information includes power configuration information, and the step of the terminal determining target information of a first positioning reference signal according to the first configuration information includes: determining a first bandwidth part (BWP) for transmitting the first positioning reference signal; determining a transmission power of the first positioning reference signal based on the power arrangement information and the first BWP.

[0046] Optionally, the first BWP may be an activation BWP for the terminal when the terminal is in an idle or inactive state.

[0047] In the embodiment of the present application, the first BWP may be the initial activation BWP of the terminal when the terminal is in an idle state or an inactive state, or may be the activation BWP that the terminal switches to in order to transmit a positioning reference signal, for example, the activation BWP that the terminal switches to when transmitting a first positioning reference signal. It should be noted that after switching the activation BWP, the current activation BWP may be retained unchanged, or the activation BWP may be switched to the initial activation BWP after transmitting the first positioning reference signal. No further limitations are provided here.

[0048] Optionally, in some embodiments, the first BWP is: Early BWP, A dedicated initial BWP used only for performing uplink positioning when the terminal is in an idle or inactive state; and At least one of the BWPs for positioning.

[0049] In the embodiment of the present application, the initial BWP may be understood as an initial BWP that is arranged when the terminal is in a connected state or a disconnected state. The dedicated initial BWP may be referred to as a second initial BWP, and is intended to represent an initial activation BWP used in a specific case when the terminal is in an idle state or an inactive state. The specific case may be a case of positioning, a case of low power consumption, etc. When the initial BWP and the second initial BWP are the same, it may be understood that the initial activation BWP used by the terminal in different states is the same. The positioning BWP may be understood as a BWP for transmitting the first positioning reference signal, and the positioning BWP may be the same as or different from the initial BWP and / or the dedicated initial BWP, and is not further limited here.

[0050] Optionally, in some embodiments, the method further comprises: receiving second configuration information transmitted by the network device; The second configuration information includes at least one of first sub-configuration information and second sub-configuration information used by the terminal in an idle state or an inactive state, the first sub-configuration information being a configuration of the initial BWP, and the second sub-configuration information being a configuration of the dedicated initial BWP or a BWP for positioning.

[0051] In the embodiment of the present application, the first configuration information and the second configuration information may be carried in the same command or the same message, or may be carried in different commands or different messages. When the terminal is in an idle state or an inactive state, the first sub-configuration information and the second sub-configuration information may exist simultaneously. In one embodiment, only one of the first sub-configuration information and the second sub-configuration information is activated, that is, when the terminal is in an idle state or an inactive state, either one of the first sub-configuration information and the second sub-configuration information is activated. In another embodiment, the first sub-configuration information and the second sub-configuration information are combined to determine the second configuration information when the terminal is in an idle state or an inactive state. In yet another embodiment, the first sub-configuration information and the second sub-configuration information are used for different purposes, for example, the first sub-configuration information is used for both random access and / or paging, and the second sub-configuration information is used for positioning, and the purposes may be arbitrarily combined, and are not limited here.

[0052] It should be noted that in the embodiment of the present application, the first sub-power configuration information and the second sub-power configuration information may belong to one configuration unit or two different configuration units.

[0053] It should be understood that when certain sub-configuration information is activated, the BWP corresponding to the sub-configuration information will be activated, and the terminal can transmit the first positioning reference signal through the currently activated BWP.

[0054] It may further be understood that when a certain BWP is activated, the corresponding configuration information is activated, and the terminal can transmit the first positioning reference signal according to the corresponding configuration information in the currently activated BWP.

[0055] Optionally, in some embodiments, the configuration information of the first BWP carries configuration information of a positioning reference signal.

[0056] In an embodiment of the present application, the configuration information of the positioning reference signal carried in the configuration information of the first BWP may include configuration information of a positioning reference signal for the terminal to perform uplink positioning in an idle state or an inactive state, or may include configuration information of a positioning reference signal for the terminal to perform uplink positioning in a connected state. In other words, in an embodiment of the present application, when the first BWP is the dedicated initial BWP or a positioning BWP, the configuration information of the positioning reference signal includes at least one of third sub-configuration information and fourth sub-configuration information, in which the third sub-configuration information is configuration information of a positioning reference signal for the terminal to perform uplink positioning in an idle state or an inactive state, and the fourth sub-configuration information is configuration information of a positioning reference signal for the terminal to perform uplink positioning in a connected state.

[0057] It should be noted that in the embodiment of the present application, the fourth sub-configuration information may include a part or all of the configurations in the first configuration information, and may further include or only include other configurations of positioning reference signals for the terminal to perform uplink positioning in a connected state other than the first configuration information.

[0058] In an embodiment of the present application, the configuration information of the first BWP may include a BWP index (ID), BWP common information and BWP dedicated information, where the configuration information of the positioning reference signal may be carried in the BWP dedicated information.

[0061] Optionally, in some embodiments, when the second enablement state identifier is not carried in the configuration information of a BWP, it indicates that the configuration information of the BWP is used for a connected state, when the second enablement state identifier is carried in the configuration information of a BWP, it indicates that the configuration information of the BWP is used for an idle state or an inactive state, or when the second enablement state identifier is carried in the configuration information of a BWP and the second enablement state identifier is a third value, it indicates that the configuration information of the BWP is used for an idle state, an inactive state or a connected state, or it indicates that the configuration information of the BWP is used only for an inactive state or a connected state, or when the second enablement state identifier is carried in the configuration information of a BWP and the second enablement state identifier is a fourth value, it indicates that the configuration information of the BWP is used for a connected state.

[0062] It should be noted that in one embodiment, when the second enabling state identifier is present, the configuration information of the first BWP may include only the first sub-configuration information or the second sub-configuration information, and the second enabling state identifier limits whether the configuration information of the first BWP is used for another state. For the same reason, it may be understood that the second enabling state identifier needs to be included in the configuration information of the first BWP when the configuration information of the first BWP includes only the first sub-configuration information or the second sub-configuration information.

[0063] For the same reason, in one embodiment, when the second enablement state identifier is present, the configuration information of the positioning reference signal may include only the third sub-configuration information or the fourth sub-configuration information, and the second enablement state identifier limits whether the configuration information of the positioning reference signal is used for another state.

[0065] In the embodiment of the present application, the first sub-power configuration information may be power control information used by the terminal in a connected state, or may be power control information used by the terminal in an idle state or an inactive state, and is not further limited here.Optionally, in some embodiments, the function of the first sub-power configuration information may be determined by the third enabling state identifier, for example, when the power configuration information includes the first sub-power control information and the third enabling state identifier, it indicates that the third enabling state identifier and the first sub-power control information are associated with each other, and at this time, if the third enabling state identifier is a first value, it may indicate that the first sub-power control information is used only in the connected state of the terminal, and if the third enabling state identifier is a second value, it may indicate that the first sub-power control information is used in the idle state or non-idle state, specifically, the first sub-power control information is used in the idle state or non-idle state. The first sub-power control information is used only in an idle state or a non-idle state; and It may be understood that the first sub-power control information is used in any one of a connected state, an idle state, or a non-idle state.

[0066] In an embodiment of the present application, the first sub-power allocation information may include at least one of a first sub-power allocation parameter and a first sub-power path loss reference signal; The first sub-power allocation parameter may include, for example, at least one of an expected received power value P0, a power adjustment coefficient α, a preamble received target power, a maximum transmission power, and a power ramp coefficient (POWER_RAMPING); The first sub-power path loss reference signal may include, for example, at least one of a first SSB, a second SSB, and a PRS, in which the first SSB may include serving cell identity information and SSB identity information, and the second SSB may include cell identity information, SSB identity information, and SSB configuration information.
