[0020] Figure 1 shows a block diagram of a wireless communication system applicable to the embodiment of this application. The wireless communication system comprises a terminal 11 and network equipment 12. Here, the terminal 11 may also be called terminal equipment or user equipment (UE), and may be a terminal-side device such as a mobile phone, tablet personal computer, laptop computer (also called a notebook computer), personal digital assistant (PDA), personal information terminal, netbook, ultra-mobile personal computer (UMPC), mobile internet device (MID), wearable device, or in-vehicle device (VUE), pedestrian terminal (PUE), etc. Wearable devices include bracelets, earphones, glasses, etc. It should be noted that the specific type of terminal 11 is not limited to the embodiment of this application.

In the embodiments relating to this application, only base stations in an NR system are given as examples, but it is necessary to explain that the specific type of base station is not limited.The core network device may be referred to as a Location Management Function (LMF), an Enhance Serving Mobile Location Center (E-SMLC), a location server, or any other appropriate term in the said field.

[0021] To facilitate understanding, some aspects of the embodiments described in this application will be explained below.

[0022] 1. The terminal state includes three types of states: Idle, Inactive, and Connected. Of these, the Connected state may also be referred to as the Radio Resource Control connected (RRC_ connected) state.

[0023] In the Idle state, a UE (User Interface Device) lacks an RRC context with network devices; that is, parameters essential for communication between the network device and the UE do not belong to a specific cell, and the network device is unaware of the existence of the UE. The UE is assigned a set of Tracking Area Identifiers (TAI lists). From the core network's perspective, the connection between the Radio Access Network (RAN) and the core network is disconnected. To reduce power consumption, the UE is in a sleep state for most of the time and therefore cannot transmit data. On the downlink, an Idle UE can periodically wake up to receive paging messages from network devices. Mobility can be handled by the UE performing cell re-selection. In the Idle state, the UE does not maintain uplink synchronization with network devices, and to transition from the Idle state to the Connected state, an RRC context must be established between the UE and the network device via Random Access.

[0024] In the RRC_Connected state, an RRC context can be established, and all parameters necessary 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 is known to belong to a cell, and a device identifier for signaling transmission between the device and the network, namely the Cell Radio Network Temporary Identifier (C-RNTI), is located there. In the connected state, mobility is controllable by the network equipment; that is, the UE provides adjacent cell measurements to the network equipment, and the network equipment commands the terminal to handover. Uplink time synchronization may or may not exist, and uplink synchronization can be established by random access when attempting to transmit data.

[0025] In the RRC_INACTIVE state, the RRC context of the network device and the UE is maintained. From the core network's perspective, the RAN side and the core network are connected. Therefore, the transition 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 through cell re-election. Therefore, RRC_INACTIVE can be considered a mixture of the idle and connected states.

[0026] Therefore, the key difference between different states lies in the mobility mechanism involved. Efficient mobility processing is a crucial part of any mobile communication system. For idle and inactive states, mobility is handled by the terminal through cell re-selection, while for connected states, mobility is handled by network equipment based on UE measurements.

[0027] The UE returns to the RRC connected state in five cases: when attempting to send data on the uplink, when a signaling procedure is initiated at the Non-Access Stratum (NAS) layer, when responding to RAN paging, when notifying network devices that the UE has left the Access Network Notification Area (RAN), and when the periodic Access Network Notification Area update timer times out.

[0028] 2. Power control and spatial relationship of the uplink positioning reference signal in the 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 placement information may be placed for each SRS resource set, i.e., the placement may be understood as a placement for each SRS resource set, or the first placement information may be placed for each SRS resource.

[0030] The path loss reference signal is used to obtain the path loss estimate of the SRS and includes downlink signals such as the serving cell's Synchronization Signal and PBCH block (SSB), adjacent cell's SSB, CSI-RS, and downlink positioning reference signal (PRS), or other SRS.

[0031] 3. Random access procedure.

[0032] A 4-step random access channel (RACH) can also be called a 4-step random access channel, and specifically, A random access procedure based on competition, and Includes random access procedures based on non-raceability.

[0033] In a "Random Access Procedure Based on Conflict," the UE sends message 1 (Msg1) to the network device. After receiving Msg1, the network device sends message Msg2, which carries uplink grant information, to the UE. Based on the uplink grant information in Msg2, the UE sends Msg3. After receiving Msg3, the network device sends Msg4 (e.g., a contention resolution identifier) ​​to the UE. The UE receives Msg4 and determines whether the contention resolution was successful. If successful, the random access procedure is considered successful; otherwise, the random access procedure is restarted.

[0034] In a "non-contradiction-based random access procedure," the network device allocates a dedicated RACH resource to the UE to grant access, the UE sends Msg1 (Random Access Request) to the network device using the dedicated resource, and after receiving Msg1, the network device sends a Msg2 message to the UE. However, if there are not enough dedicated RACH resources, the network device instructs the UE to initiate conflict-based random access (RA).

[0035] 2-step RACH includes the following steps: 1. The network device places new two-step random access placement information on the UE, including, for example, transmission resource information corresponding to MsgA and MsgB. 2. The UE triggers a two-step RACH procedure. It sends request information (MsgA) to the network device, for example, via a Physical Uplink Shared Channel (PUSCH). Simultaneously, the UE may also send Physical Random Access Channel (PRACH) information to the network device. 3. The network device sends confirmation information (MsgB) to the UE. If the UE fails to receive MsgB, it sends MsgA again.

[0036] IV. Uplink positioning procedure.

[0037] The uplink positioning procedure includes the following steps: 1. The Location Management Function (LMF) and TRP exchange placement information. 2. LMF and UE exchange capability information. 3. Request positioning using the New Radio Positioning Protocol A (NRPPa). 4. The base station determines the uplink (UL) SRS configuration. 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, with reference to the drawings, specific embodiments and the uplink positioning processing method provided in the embodiments of this application, when applied thereto, will be described in detail.

[0039] Please refer to Figure 2, which is a flowchart of the uplink positioning processing method provided in an embodiment of this application, the method being performed by a terminal, as shown in Figure 2, Step 201: The terminal receives first placement information transmitted by the network device, The step 202 includes the terminal determining target information for the first positioning reference signal based on the first placement information, The first arrangement information includes at least one of power arrangement information and spatial relationship arrangement information, and if the first arrangement information includes the power arrangement information, the target information includes the transmitted power, and if the first arrangement information includes spatial relationship arrangement information, the target information includes the spatial relationship, and the first positioning reference signal is for performing uplink positioning when the terminal is idle or inactive.

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

[0041] It should be understood that the power allocation information and spatial relationship allocation information may be carried in the same command or message, or in different commands or messages, and this is not further limited. It should also be understood that the first allocation information may carry other information besides the power allocation information and spatial relationship allocation information. Since the target information for the first positioning reference signal is determined by the first allocation information, the first positioning reference signal can be transmitted using the target information when the terminal is idle or inactive, and furthermore, uplink positioning can be achieved even when the terminal is idle or inactive.

[0042] It should be explained that the terminal may determine the above target information when it is connected, or when it is idle or inactive. This is not a further limitation.

[0043] It should be explained that the terminal may receive the above-mentioned first configuration information when it is connected, or it may receive the above-mentioned first configuration information when it is idle or inactive.

[0044] In the embodiments of this application, a terminal receives first placement information transmitted by a network device, the terminal determines target information for a first positioning reference signal based on the first placement information, the first placement information includes at least one of power placement information and spatial relationship placement information, the target information includes transmitted power if the first placement information includes power placement information, the target information includes spatial relationships if the first placement information includes spatial relationship placement information, and the first positioning reference signal is for the terminal to perform uplink positioning when it is idle or inactive. In this way, when the terminal is idle or inactive, it can transmit an uplink positioning reference signal based on the determined target information, thereby avoiding the terminal having to transition to a connected state and transmit a positioning reference signal. Accordingly, the embodiments of this application reduce power consumption and delay due to terminal positioning.

[0045] In some embodiments, the first placement information includes power placement information, and the step of the terminal determining target information for a first positioning reference signal using the first placement information is: The steps include determining a first bandwidth part (BWP) for transmitting the first positioning reference signal, The step includes determining the transmission power of the first positioning reference signal based on the power distribution information and the first BWP.

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

[0047] In the embodiments of this application, the first BWP may be the initial activation BWP of the terminal when the terminal is idle or inactive, or it may be an activation BWP that the terminal switches to in order to transmit a positioning reference signal, for example, an 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 currently active BWP may be kept unchanged, or after transmitting the first positioning reference signal, the activation BWP may be switched to the initial activation BWP. There are no further limitations.

[0048] In some of the selectable embodiments, the first BWP is, Initial BWP, A dedicated initial BWP used solely for performing uplink positioning when the aforementioned terminal is idle or inactive, and It is at least one of the positioning BWPs.

[0049] In the embodiments of this application, the initial BWP may be understood as the initial BWP that is deployed when the terminal is connected or disconnected. The dedicated initial BWP may also be called the second initial BWP and is intended to represent the initial activation BWP used in specific cases when the terminal is idle or inactive. The aforementioned specific cases may be positioning, low power consumption, etc. If the initial BWP and the second initial BWP are the same, it may be understood that the initial activation BWP used in different states of the terminal is the same. The positioning BWP may be understood as the BWP for transmitting the first positioning reference signal, and this positioning BWP may be the same as, or different from, the initial BWP and / or dedicated initial BWP, and is not further limited thereto.

[0050] Selectable embodiments, the method, The step further includes receiving second placement information transmitted by the aforementioned network device, The second configuration information includes at least one of a first sub-configuration information and a second sub-configuration information used by the terminal when it is idle or inactive, wherein the first sub-configuration information is the configuration of the initial BWP, and the second sub-configuration information is the configuration of the dedicated initial BWP or positioning BWP.

[0051] In the embodiments of this application, the first and second configuration information may be carried in the same command or message, or in different commands or messages. The first and second sub-configuration information may exist simultaneously when the terminal is idle or inactive. In one embodiment, only one of the first and second sub-configuration information is activated; in other words, when the terminal is idle or inactive, either the first or second sub-configuration information is activated. In another embodiment, the first and second sub-configuration information are combined to determine the second configuration information when the terminal is idle or inactive. In yet another embodiment, the first and second sub-configuration information are used for different purposes; for example, the first sub-configuration information may be used for random access and / or paging, and the second sub-configuration information may be used for positioning, and these purposes may be combined in any way, but are not limited thereto.

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

[0053] What needs to be understood is that when a sub-positioning information is activated, the BWP corresponding to that sub-positioning information is activated, and the terminal can transmit the first positioning reference signal using the currently activated BWP.

[0054] Furthermore, it can be understood that when a BWP is activated, the corresponding placement information is activated, and the terminal can transmit the first positioning reference signal using the placement information corresponding to the currently activated BWP.

[0062] In one embodiment, when a second enable state identifier exists, the placement information of the first BWP may include only the first sub-placement information or the second sub-placement information, and it should be noted that the second enable state identifier limits whether or not the placement information of the first BWP is used for a different state. For the same reason, it may be understood that the second enable state identifier needs to be included in the placement information of the first BWP when the placement information of the first BWP includes only the first sub-placement information or the second sub-placement information.

[0063] For the same reason, in one embodiment, when a second enable state identifier exists, the positioning reference signal placement information may include only the third sub-placement information or the fourth sub-placement information, and the second enable state identifier limits whether the positioning reference signal placement information is used for a different state. For the same reason, it may be understood that the second enable state identifier must be included in the positioning reference signal placement information when the positioning reference signal placement information includes only the third sub-placement information or the fourth sub-placement information.

Optionally, in some embodiments, the function of the first sub-power allocation information may be determined by the third enable state identifier, for example, when the power allocation information includes the first sub-power control information and the third enable state identifier, this indicates that the third enable state identifier and the first sub-power control information are related, where a first value for the third enable state identifier indicates that the first sub-power control information is used only in the connected state of the terminal, and a second value indicates that the first sub-power control information is used in an idle or non-idle state, specifically, the use of the first sub-power control information in an idle or non-idle state means The first sub-power control information is used only in idle or non-idle states, and It may be understood that the first sub-power control information is used for the connected state, idle state, or non-idle state, or any one of these.

[0112] To better understand this application, the implementation procedure will be described in detail below with several specific examples.

[0113] Example 1: SRS is transmitted in the initial BWP. In the embodiment of this application, even if the terminal is in an inactive / idle state, SRS is transmitted in the activation BWP, i.e., the SRS is transmitted in the initial BWP.

[0122] Selectively, the instruction information for the first target placement or the second target placement is carried to the RRC inactive placement information.

[0123] Selectively, the RRC inactive placement information is included in the RRC release information.

[0124] Example 2: The SRS is transmitted using a dedicated initial BWP.

[0125] Embodiment 2 differs from Embodiment 1 in that the placement information of the Dedicated Initial uplink BWP is different from the placement information of the Initial uplink BWP. For example, in the embodiment of this application, the placement information of the Dedicated Initial uplink BWP is, Bwp ID, BWP common information, and It may also include BWP-specific information that carries the first SRS placement information and / or the second SRS placement information.

[0126] The following actions are available to the device: 1. The BWP transmitting the SRS differs from the initial BWP, and the differences include one of the following: differences in time-frequency resources and differences in Dedicated information. For example, the initial BWP does not include SRS placement information, or the SRS placement information, such as power placement information, is different. 2. Unlike the BWP that sends the preamble / MsgA mentioned above, the BWP that sends the SRS has a transmission interval greater than the threshold of 1. 3. The BWP that transmits the SRS is different from the BWP that transmits the preamble / MsgA, and the time interval between transmissions is less than threshold 1, and it is not desired to transmit the SRS. 4. If the BWP resource sending the SRS is different from the initial BWP of the downlink, the time interval between the SRS transmission and the paging reception is greater than threshold 2. 5. If the BWP resource sending the SRS is different from the initial BWP of the downlink, the time interval between SRS transmission and paging reception is less than threshold 2, and it is not desired to send the SRS. 6. At times when the UE is transmitting the SRS or at specific times, the Dedicated Initial uplink BWP is an activated BWP and is selectable; at other times, the Initial BWP is an activated BWP and is selectable; in some embodiments, the Dedicated Initial uplink BWP is periodically activated according to the SRS cycle and is selectable; in some embodiments, the Dedicated Initial uplink BWP is periodically deactivated according to the SRS cycle and is selectable; and in some embodiments, the Dedicated Initial uplink BWP activation time is related to the SRS transmission time.

[0133] Furthermore, positioning BWPs are assigned to each serving cell. Positioning BWPs in serving cells of the same base station have a correspondence, or in other words, they can be decoupled from the serving cell. For example, they have the same time-frequency resources and / or the same SRS placement information.

[0134] Example 4: When the cell in service changes, the arrangement of the uplink positioning reference signal is updated, as shown in Figure 3. Step 301 involves the network device transmitting the uplink positioning reference signal placement information in an RRC release message or RRC state suspend message, Step 302, in which the terminal may send a preamble when switching to a cell in the area, Step 303, in which the terminal receives a Random Access Response (RAR) sent by a network device, Step 304 involves the terminal sending an RRC resume request to the network device, Step 305 in which the terminal receives the Contention Resolution, Step 306, after the terminal successfully accesses a new cell, the network equipment resends an RRC release message or an RRC state suspend message, and transmits the first target configuration and / or second target configuration of the uplink positioning reference signal in the RRC release message or RRC state suspend message.
