Furthermore, the term “and / or” as used herein means including any or all possible combinations of one or more related enumerated items.

[0019] In the embodiments of this disclosure, various types of information may be described using terms such as First, Second, Third, etc., but it should be understood that this information should not be limited to these terms. These terms are used solely to distinguish information of the same type from one another. For example, without departing from the scope of the embodiments of this disclosure, First Information may be called Second Information, and similarly, Second Information may be called First Information. Depending on the context, the word “case” as used herein may be interpreted as “when,” “and,” or “in response to having decided.”

[0020] Referring to Figure 1, a schematic diagram of the structure of a wireless communication system according to an embodiment of the present disclosure is shown. As shown in Figure 1, the wireless communication system is a communication system based on cellular mobile communication technology, and the wireless communication system may include at least one UE 11 and at least a plurality of core network devices 12.

[0021] Here, UE11 may be a device that provides voice and / or data connectivity to the user. UE11 may communicate with one or more core networks via a RadioAccess Network (RAN). UE11 may be an Internet of Things UE, such as a sensor device, a mobile phone (or "cellular" phone), or a computer with an Internet of Things UE, and may be, for example, a fixed, portable, pocket-sized, handheld, computer-integrated, or vehicle-mounted device. Examples include a Station (STA), subscriber unit, subscriber station, mobile station, mobile, remote station, access point, remote terminal, access terminal, user terminal, user agent, user device, or user equipment (UE). Alternatively, UE11 may be an unmanned aerial vehicle (UAV) device. Alternatively, UE11 may be an in-vehicle device such as a vehicle computer with wireless communication capabilities, or a wireless communication device externally connected to a vehicle computer. Alternatively, UE11 may be a roadside device such as a streetlamp, signal light, or other roadside device with wireless communication capabilities.

[0022] The access device 12 may be a network device in a wireless communication system. The wireless communication system may be a fourth-generation mobile communication (4G) system, also known as a Long-Term Evolution (LTE) system, or a 5G system, also known as a newradio (NR) system or a 5G NR system. Alternatively, the wireless communication system may be a system of the next generation beyond the 5G system. Here, the access network in the 5G system may be called an NG-RAN (New Generation-Radio Access Network). Alternatively, it may be an MTC system.

[0023] Here, the access network device 12 may be an evolved access device (eNB) used in a 4G system. Alternatively, it may be a device such as a transmission and reception point (TRP), or a network device in a subsequent evolved communication system. Alternatively, the access device 12 may be a centralized distributed architecture access device (gNB) used in a 5G system. When the access network device 12 uses a centralized distributed architecture, the access network device 12 typically includes a central unit (CU) and at least two distributed units (DU). The central unit is provided with a protocol stack for the Packet Data Convergence Protocol (PDCP) layer, the Radio Link Control (RLC) layer, and the Media Access Control (MAC) layer, and the distributed units are provided with a protocol stack for the Physical (PHY) layer. The embodiments of this disclosure do not limit the specific implementation of the access network device 12.

[0024] A wireless connection between the access device 12 and the UE 11 can be established by using a wireless air interface. In different embodiments, the wireless air interface may be a wireless air interface based on the fourth-generation mobile communications network technology (4G) standard, or it may be a wireless air interface based on the fifth-generation mobile communications network technology (5G) standard, for example, the wireless air interface may be a nuradio, or it may be a wireless air interface based on the 5G next-generation mobile communications network technology standard.

[0025] In one embodiment, if a UE acquires an uplink reference positioning signal configuration, it may release the uplink reference positioning signal configuration when a cell is reselected or when the UE restores RRC connectivity with a first network device. However, in this case, the UE may reselect a cell in which the uplink reference positioning signal configuration is still valid, or the UE itself may not have moved, i.e., the uplink reference positioning signal configuration may still be valid when the UE releases it. Therefore, releasing the uplink reference positioning signal configuration based on a cell reselection event, or releasing the uplink reference positioning signal configuration based on an event in which the UE restores RRC connectivity with a first network device, is an unnecessary release.

[0026] After the uplink reference positioning signal configuration is unnecessarily released by the UE, it may request the uplink reference positioning signal configuration again from the first network device, thereby causing the re-request for the uplink reference positioning signal configuration that was caused by the unnecessary release.

[0027] Referring to Figure 2, this is a schematic diagram of the processing method for the uplink positioning reference signal configuration. This method can be performed by the UE and includes the following steps.

[0028] Step S100: Based on the pre-configured rules, the uplink positioning reference signal configuration is released or saved, and the uplink positioning reference signal configuration is used for uplink positioning when the UE is in an RRC-disconnected state.

[0029] Exemplary, user equipment (UE) can be any communication device shown in Figure 1. Specifically, these include mobile phones, tablet computers, wearable devices, in-vehicle devices, smart home devices, smart office devices, and / or aircraft devices.

[0030] Before performing step S100, the method further includes the following: The system receives the uplink positioning reference signal configuration transmitted from the first network device.

[0031] For example, receiving an uplink positioning reference signal configuration transmitted from the first network device includes: The UE receives an RRC message instructing the UE to move from an RRC connected state to an RRC disconnected state, and the RRC message includes an uplink positioning reference signal configuration.

[0032] For example, a UE receives an RRC release message that instructs the UE to move from an RRC connected state to an RRC disconnected state. This RRC disconnected state includes the RRC idle state and / or the RRC inactive state.

[0033] The uplink positioning reference signal configuration may include at least one of the following: Uplink positioning reference signal resource configuration: At least the transmission time and frequency domain resources for the UE to transmit the uplink positioning reference signal; Uplink positioning reference signal measurement reporting configuration: The terminal must at least indicate the transmission time and frequency domain resources for reporting the measurement results; Timing configuration: Used to indicate the validity period of the uplink positioning reference signal configuration, and this timing configuration includes, but is not limited to, the value of the Timealignment timer (TAT); Region configuration: Indicates the effective region included in the uplink positioning reference signal configuration.

[0034] Exemplary, such pre-configured rules may be arbitrary predefined rules. Pre-configured rules may be agreed upon by the protocol or indicated by uplink positioning reference signal configuration information. For example, uplink positioning reference signal configuration may also include uplink positioning reference signal release rule configurations.

[0035] In some embodiments, releasing or saving the uplink positioning reference signal configuration based on pre-configured rules includes: If a release event that satisfies the release rule configuration is detected, the uplink positioning reference signal configuration is released; otherwise, the uplink positioning reference signal configuration is retained.

[0036] Furthermore, exemplary actions such as releasing or saving the uplink positioning reference signal configuration based on pre-configured rules may include: Continue saving the uplink positioning reference signal configuration when re-selecting a cell; and / or, Do not release the uplink positioning reference signal configuration when re-selecting a cell; and / or, If the UE has now restored RRC connectivity with the service cell, continue to preserve the uplink positioning reference signal configuration; and / or, If the UE has now restored RRC connectivity with the service cell, do not release the uplink positioning reference signal configuration; and / or, If the UE's current location is within the valid range of the uplink positioning reference signal configuration, continue to save the uplink positioning reference signal configuration; and / or, If the UE's current location is within the valid range of the uplink positioning reference signal configuration, do not release the uplink positioning reference signal configuration; and / or, If the UE moves outside the effective range of the uplink positioning reference signal configuration, release the uplink positioning reference signal configuration.

[0037] After a UR enters a disconnected state from a connected state, it may subsequently enter a connected state again from a disconnected state. If the UE does not release or saves an uplink positioning reference signal configuration previously received, the saved uplink positioning reference signal configuration can be used continuously, reducing signaling overhead by decreasing the number of uplink positioning reference signal configuration requests that the UE sends to the first network device.

[0038] In other words, in embodiments of the present disclosure, based on pre-configured rules, the UE releases or saves the uplink positioning reference signal configuration for RRC disconnection states, thereby reducing releases that occur when the UE does not need to release the uplink positioning reference signal configuration for RRC disconnection states, reducing the re-requests for the uplink positioning reference signal configuration to the first network device due to excessive releases by the UE, and reducing signaling overhead.

[0039] In one embodiment, the uplink position reference signal configuration of the UE in the RRC-disconnected state includes an effective region.

[0040] Within the effective region, the uplink position reference signal configuration is effective; outside the effective region, the uplink position reference signal configuration is ineffective.

[0041] Exemplary, the effective region may include one or more cells.

[0042] The region configuration indicating the effective area may include the following: Area identifiers: Different areas have different area identifiers. These area identifiers may include geographical area identifiers such as tracking area identifiers and / or wireless access notification area identifiers.

[0043] Cell identifier: Indicates a cell contained within the valid area. This cell identifier can be carried by a cell list.

[0044] In one embodiment, the effective region of the uplink positioning reference signal configuration may be a single connected continuous region.

[0045] In one embodiment, if the effective area includes multiple cells, the multiple cells are distributed contiguously or adjacently.

[0046] For example, the effective region may be a region within the effective region list, which may be represented as a list of Physical Cell Identifiers (PCIs). For instance, the PCI list may include PCI1, PCI2, and / or PCI3.

[0047] In one embodiment, referring to Figure 3, is another schematic diagram of a method for processing an uplink positioning reference signal configuration, which is performed by the UE and includes the following steps.

[0048] Step S201: If a UE in an RRC-disconnected state performs cell reselection and the target cell for cell reselection is located within the valid area, save the uplink positioning reference signal configuration.

[0049] For example, preservation may also mean continuous preservation.

[0050] For example, if a UE in an RRC-disconnected state performs cell reselection and the target cell for cell reselection is located within the valid area, saving the uplink positioning reference signal configuration may include the following: If an RRC idle UE performs cell reselection and the target cell for cell reselection is located within the valid area, save the uplink positioning reference signal configuration; and / or, If a UE in an RRC inactive state performs cell reselection and the target cell for cell reselection is located within the valid area, the uplink positioning reference signal configuration is saved.

[0051] Because the target cell remains within the valid area after cell re-selection, the UE continues to store the uplink positioning reference signal configuration. After cell re-selection, or after the UE returns from an RRC connected state to an RRC disconnected state, the UE can continue to use the stored uplink positioning reference signal configuration to transmit the uplink positioning reference signal. This eliminates the need for the UE to re-request the uplink positioning reference signal configuration from the first network device, and the first network device does not need to retransmit the uplink positioning reference signal configuration to the UE.

[0052] For example, if a UE in an RRC-disconnected state performs cell reselection and the PCI of the target cell for cell reselection is included in the physical cell identifier list, the uplink positioning reference signal configuration is saved.

[0053] In one embodiment, the method includes the following: If the UE in the RRC-disconnected state performs cell reselection and the target cell for cell reselection is located within the valid area, the uplink positioning reference signal configuration is not released.

[0054] Here, "not releasing" could also mean "preserving."

[0055] After receiving an uplink positioning reference signal configuration transmitted from the first network device, the UE saves the uplink positioning reference signal configuration. If the UE, which is in an RRC-disconnected state, performs cell reselection and the target cell for cell reselection is located within the effective area, the uplink positioning reference signal configuration is not released and is continuously saved. This allows the UE to continue using the saved uplink positioning reference signal configuration to transmit uplink positioning reference signals after cell reselection or after the UE has returned from an RRC-connected state to an RRC-disconnected state.

[0056] In one embodiment, with reference to Figure 4, another schematic diagram of a method for processing the uplink positioning reference signal configuration is shown. This method is performed by the UE and includes the following steps:

[0057] Step S202: If a UE in an RRC-disconnected state performs cell reselection and the target cell for cell reselection is located outside the valid area, release the uplink positioning reference signal configuration.

[0058] In this context, "release" may include deletion.

[0059] Since the target cell after cell reselection is outside the valid area, the UE cannot continue transmitting uplink positioning reference signals based on the uplink positioning reference signal configuration within the target cell. By releasing the uplink positioning reference signal configuration, the UE can receive the uplink positioning reference signal configuration retransmitted by the first network device and transmit uplink positioning reference signals based on the reconfigured uplink positioning reference signal configuration.

[0060] For example, the effective area is indicated by the PCI in the Physical Cell Identifier (PCI) list.

[0061] If a UE in an RRC-disconnected state performs cell reselection and the PCI of the target cell for cell reselection is not included in the physical cell identifier list, the uplink positioning reference signal configuration is released. In one embodiment, referring to Figure 5, another schematic diagram of a method for processing the uplink positioning reference signal configuration is shown, which is performed by the UE and includes the following steps.

[0062] Step S300: A UE in the RRC connected state performs a cell handover, and the uplink positioning reference signal configuration is released when the UE is in the RRC disconnected state.

[0063] In this case, cell handover for a UE in an RRC-connected state is performed directly based on the UE cell handover event, and the uplink positioning reference signal configuration, which was in an RRC-disconnected state when the UE was not connected, is released. At this time, if an effective region is set for the uplink positioning reference signal configuration, it is not considered whether the target cell to which the cell handover occurred is within the effective region.

[0064] When a UE moves, it is understood that the UE's service cell has changed, and in this case, to simplify processing for the first network device, the UE can release the uplink positioning reference signal configuration. If the UE needs to use the uplink positioning reference signal configuration again, it can request it again from the cell after the handover, or the LocationManage Function (LMF) can trigger the base station to provide the uplink positioning reference signal configuration to the UE.

[0065] In one embodiment, with reference to Figure 6, another schematic diagram of a method for processing the uplink positioning reference signal configuration is shown. This method is performed by the UE and includes the following steps:

[0066] Step S400: If a UE in RRC connection state performs a cell handover and the handed-over target cell is located within the effective area, save the uplink positioning reference signal configuration.

[0067] After a UE in the RRC connected state performs a cell handover, if the target cell is located within the valid area, the uplink positioning reference signal configuration remains valid in the target cell, and the UE can transmit an uplink positioning reference signal based on the saved uplink positioning reference signal configuration after re-entering the disconnected state from the connected state.

[0068] This reduces the number of requests for the uplink positioning reference signal configuration that the UE sends to the first network device, and reduces the process by which the first network device retransmits the uplink positioning reference signal configuration to the UE, thereby reducing signaling overhead.

[0069] In this case, in a UE with an RRC connection, to expand the scope of the uplink positioning reference signal configuration, when the UE performs a handover, it can decide whether or not to release the saved uplink positioning reference signal configuration based on whether or not the handed-over target cell is located within the effective area.

[0070] In one embodiment, the method further includes: If the UE in the RRC connection state performs a cell handover and the handed-over target cell is located within the effective area, the uplink positioning reference signal configuration is not released.

[0071] After the UE receives the uplink positioning reference signal configuration transmitted from the first network device, it saves the configuration, and if the UE, while in an RRC connected state, performs a cell handover and the handed-overed target cell is located within the valid area, the uplink positioning reference signal configuration is not released but continues to be saved. This makes it easier for the UE to continue using the saved uplink positioning reference signal configuration to transmit uplink positioning reference signals after cell reselection or after the UE returns from an RRC connected state to an RRC disconnected state.

[0072] In one embodiment, with reference to Figure 7, another schematic diagram of a method for processing the uplink positioning reference signal configuration is shown. This method is performed by the UE and includes the following steps:

[0073] Step S500: If a UE in RRC connection state performs a cell handover and the handed-over cell is located outside the effective area, the uplink positioning reference signal configuration is released.

[0074] If a UE in an RRC-connected state performs a cell handover and the handed-over target cell is located outside the effective area, the UE releases the uplink positioning reference signal configuration when it is in an RRC-disconnected state to ensure that the UE can acquire a valid uplink positioning reference signal configuration within the target cell, thereby allowing the UE to acquire a valid uplink positioning reference signal configuration again within the target cell.

[0075] In one embodiment, the first network device configures the UE with an uplink positioning reference signal (SRS) configuration when the radio resource control (RRC) is inactive, and the UE can release the SRS configuration in the following cases: When the UE's RRC layer receives a release request from the terminal's Media Access Control (MAC) layer requesting the RRC layer to release the uplink positioning reference configuration; When the UE's RRC layer receives a Radio Resource Control Restoration message (RRC resume message) sent from the first network device, this is used to instruct the RRC-disconnected UE to enter an RRC-connected state; When the UE's RRC layer receives a Radio Resource Control Establishment (RRC setup) message sent from the first network device, this is used to instruct the RRC-connected UE to enter the RRC-connected state.

[0076] Exemplary, a UE may include: an RRC layer used to control the RRC connection between the terminal and a first network device; and a MAC layer, the lowest layer below the RRC layer, which can monitor a locator corresponding to the uplink positioning reference signal configuration. In some cases, if a timer times out, the MAC layer may send a release request to the RRC layer.

[0077] The timer may be a timing adjustment timer for the uplink positioning reference signal configuration. This timer is used to time the validity period of the uplink positioning reference signal configuration. The timing adjustment timer may be associated with both the uplink positioning reference signal configuration and TimingAdvance (TA).

[0078] When the time adjustment timer is active, the uplink positioning reference signal configuration and the current TA values ​​are valid. When the time adjustment timer times out, the uplink positioning reference signal configuration and the current TA values ​​become invalid.

[0079] If any of the timing reference signal configurations become invalid, the UE cannot continue transmitting the uplink positioning reference signal based on the uplink positioning reference signal configuration.

[0080] In some embodiments, this method includes: The UE transmits an uplink positioning reference signal based on the uplink positioning reference signal configuration while the RRC is not connected; and / or, The UE, while in RRC connection state, stops transmitting the uplink positioning reference signal based on the uplink positioning reference signal configuration.

[0081] In one embodiment, with reference to Figure 8, another schematic diagram of a method for processing the uplink positioning reference signal configuration is shown. This method is performed by the UE and includes the following steps:

[0082] Step S600: Receive a first message transmitted from a first network device, save the uplink positioning reference signal configuration, and use the first message to cause a UE that is in an RRC-disconnected state to enter an RRC-connected state.

[0083] After the UE transitions from an RRC-disconnected state to an RRC-connected state, the uplink positioning reference signal configuration from when the UE was in the RRC-disconnected state is continuously saved. This allows the UE to transmit an uplink positioning reference signal based on the saved uplink positioning reference signal without having to re-request the uplink positioning reference signal configuration when it enters the RRC-disconnected state again.

[0084] For example, receive a first message sent from a first network device to bring a UE that is in an RRC-disconnected state into an RRC-connected state, and save the uplink positioning reference signal configuration.

[0085] In one embodiment, the first message that causes a UE in an RRC-disconnected state to enter an RRC-connected state is a message that causes a UE in a disconnected state to enter a connected state.

[0086] For example, the first message that causes a UE that is not connected to RRC to enter an RRC-connected state may include the following: RRC recovery (RRC lapse) message; and / or, RRC setup message.

[0087] In one embodiment, the method further includes: When a first message is received from the first network device, the uplink positioning reference signal configuration is not released.

[0088] After the UE transitions from an RRC-disconnected state to an RRC-connected state, the uplink positioning reference signal configuration is not released. This allows the UE to transmit an uplink positioning reference signal based on the stored uplink positioning reference signal without having to re-request the uplink positioning reference signal configuration when it enters an RRC-disconnected state again.

[0089] Referring to Figure 9, an embodiment of the present disclosure provides a schematic diagram of a method for processing an uplink positioning reference signal configuration, which is performed by a UE and includes the following steps:

[0090] Step S601: Receive an RRC recovery message and save the uplink positioning reference signal configuration when the UE is in an RRC disconnected state.

[0091] The RRC recovery message allows the UE to transition from an RRC inactive state to an RRC connected state, and the UE establishes a connection with the first network device based on the RRC recovery message. In this case, the UE saves the uplink positioning reference signal configuration for the RRC disconnected state, and after the UE enters the RRC disconnected state again, the uplink positioning reference signal is transmitted based on the saved RRC disconnected uplink positioning reference signal configuration, and the UE's positioning is achieved.

[0092] In one embodiment, with reference to Figure 10, another schematic diagram of a method for processing the uplink positioning reference signal configuration is shown. This method is performed by the UE and includes the following steps:

[0093] Step S602: Receive the RRC establishment message and save the uplink positioning reference signal configuration when the UE is in an RRC disconnected state.

[0094] The RRC establishment message allows the UE to transition from an idle state to an RRC connected state, in which case the UE saves the uplink positioning reference signal configuration while the UE is in an RRC disconnected state. This makes it easier for the UE to transmit uplink positioning reference signals based on the saved uplink positioning reference signal configuration after transitioning from an RRC connected state back to an RRC disconnected state, thereby enabling the UE to position itself. Unnecessary releases can be reduced, thereby reducing the request for uplink positioning reference signal configurations that the UE sends to the first network device, and thus saving signaling overhead.

[0095] In one embodiment, referring to Figure 11, another schematic diagram of a method for processing an uplink positioning reference signal configuration is shown, which is performed by a UE, and this method further includes the following steps.

[0096] Step S700: The UE receives an RRC release message sent from the first network device, and the RRC release message is used to bring the UE, which is in the RRC connected state, into the RRC disconnected state.

[0097] Step S800: Continue using the stored uplink positioning reference signal configuration based on the instruction information contained in the RRC release message.

[0098] After receiving the RRC release message, the UE enters the RRC disconnected state from the RRC connected state based on the RRC release message, and disconnects the RRC connection with the first network device. At the same time, the UE decides whether to continue using the stored uplink positioning reference signal configuration based on the instruction information contained in the RRC release message. If the instruction information contained in the RRC release message instructs the UE to continue using the stored uplink positioning reference signal configuration, the UE transmits the uplink positioning reference signal based on the stored uplink positioning reference signal configuration.

[0099] For example, the instruction information included in the RRC release message may instruct the UE to continue using the uplink positioning reference signal configuration stored in the UE.

[0100] For example, the instruction information included in the RRC release message includes a first instruction; or, the instruction information included in the RRC release message includes a second instruction and a third instruction, and so on.

[0101] For example, the instruction information included in the RRC release message may be carried (or included) by a pre-configured field, that is, the instruction information of the RRC release message includes a pre-configured field, and the information carried by the pre-configured field is information indicating whether the UE will continue to use the stored uplink positioning reference signal configuration.

[0102] In one embodiment, referring to Figure 12, is another schematic diagram of a method for processing an uplink positioning reference signal configuration, which is performed by the UE, and after saving the uplink positioning reference signal configuration, the method further includes the following steps.

[0103] Step S1000: Based on whether or not an RRC release message has been received from the first network device, it is determined whether or not to continue using the stored uplink positioning reference signal configuration.

[0104] In this embodiment, the UE determines whether to continue using the stored uplink positioning reference signal configuration based on the protocol agreement and whether or not it has received an RRC release message transmitted from the first network device. If an RRC release message is received, the stored uplink positioning reference signal configuration is continued to be used. If an RRC release message is not received, the stored uplink positioning reference signal configuration is not continued to be used.

[0105] For example, if an RRC release message is not received, the stored uplink positioning reference signal configuration is released.

[0106] In one embodiment, referring to Figure 13, is another schematic diagram of a method for processing an uplink positioning reference signal configuration, which is performed by the UE and further includes the following steps.

[0107] Step S1100: When saving the uplink positioning reference signal configuration, pause or stop the timer associated with the uplink positioning reference signal configuration.

[0108] For example, when saving an uplink positioning reference signal configuration, pausing or stopping timers associated with the uplink positioning reference signal configuration may include: When the UE enters an RRC connection state and saves the uplink positioning reference signal configuration, the timers associated with the uplink positioning reference signal configuration are paused or stopped.

[0109] In one embodiment, the method for processing the uplink positioning reference signal configuration further includes: If a UE in an RRC-disconnected state performs cell reselection, and the target cell for cell reselection is located within the valid area, and the uplink positioning reference signal configuration is not saved or released, the timer associated with the uplink positioning reference signal configuration is paused or stopped; or If the UE in the RRC connection state performs a cell handover, and the handed-over target cell is located within the valid area and does not save or release the uplink positioning reference signal configuration, the timer associated with the uplink positioning reference signal configuration is paused or stopped; or If the UE does not enter an RRC-connected state from an RRC-disconnected state based on a first message transmitted from a first network device and does not save or release the uplink positioning reference signal configuration, the timer associated with the uplink positioning reference signal configuration is paused or stopped, and the first message is used to instruct the UE, which is in the RRC-disconnected state, to enter an RRC-connected state.

[0110] By pausing or stopping the timer associated with the uplink positioning reference signal configuration, unnecessary release of the uplink positioning reference signal configuration can be reduced, thereby reducing the number of times the UE sends requests for the uplink positioning reference signal configuration to the first network device, and saving signaling overhead.

[0111] For example, if the UE receives an RRC recovery message and does not save or release the uplink position reference signal configuration, the timer associated with the uplink position reference signal configuration will be paused or stopped.

[0112] For example, if the UE receives an RRC establishment message and does not save or release the uplink position reference signal configuration, the timer associated with the uplink position reference signal configuration will be paused or stopped.

[0113] In one embodiment, since the release of the uplink positioning reference signal configuration is related to a MAC layer timer, after the UE receives an RRC recovery message or an RRC establishment message and the UE decides to save the uplink positioning reference signal configuration, the UE's RRC layer instructs the MAC layer to pause or stop the timer associated with the uplink positioning reference signal configuration.

[0114] After receiving an RRC establishment message or an RRC recovery message, the UE can pause or stop the timer associated with the uplink positioning reference signal configuration, reducing the unnecessary release of the uplink positioning reference signal configuration. This reduces the number of times the UE sends requests for the uplink positioning reference signal configuration to the first network device, saving signaling overhead.

[0115] The timer associated with the uplink positioning reference signal configuration may include a time adjustment timer for the uplink positioning reference signal configuration.

[0116] A time adjustment timer can be used to time the validity period of the uplink positioning reference signal configuration.

[0117] The time adjustment timer can simultaneously associate the uplink positioning reference signal configuration with the timing advance (ta).

[0118] When the time adjustment timer is activated, the uplink positioning reference signal configuration and the current value of the TA are valid. When the time adjustment timer times out, the uplink positioning reference signal configuration and the current value of the TA become invalid.

[0119] If a timing reference signal configuration is invalid, the UE cannot continue to transmit uplink positioning reference signals based on the uplink positioning reference signal configuration.

[0120] In some embodiments, the timer is maintained and monitored by the MAC layer of the terminal, and may also be called a MAC timer.

[0121] In some embodiments, the timer may be used to share a timer for TimingAdvance (ta). If the timer times out due to a change in the UE's TA, the timer timeout causes the UE's MAC layer to send a release request to the UE's RRC layer.

[0122] Pausing the timer may include stopping the timer's timing and maintaining the current timing value.

[0123] Stopping the timer may include stopping the timer's timing and setting the timer's timing value to its initial value.

[0124] Furthermore, this method may include, for example: When the UE enters the RRC connection state and releases the uplink position reference signal configuration, it releases the timers associated with the uplink position reference signal configuration.

[0125] In one embodiment, referring to Figure 14, is another schematic diagram of a method for processing an uplink positioning reference signal configuration, which is performed by the UE and, after saving the uplink positioning reference signal configuration based on pre-configured rules, the method further includes the following steps.

[0126] Step S1200: Based on the RRC release message received from the first network device, it is determined whether or not to continue using the uplink positioning reference signal configuration.

[0127] Step S1201: If it is decided to use the uplink positioning reference signal configuration, a timer associated with the uplink positioning reference signal configuration is started at the time it is decided to continue using the uplink positioning reference signal configuration, and this timer is used to time the validity period of the uplink positioning reference signal configuration.

[0128] For example, if a saved uplink positioning reference signal configuration is to be used continuously, starting the timer associated with the uplink positioning reference signal configuration when the UE decides to continue using the uplink positioning reference signal configuration may include the following: If the UE returns to an RRC-disconnected state and continues to use a saved uplink positioning reference signal configuration, the timer associated with the uplink positioning reference signal configuration is started at the time the decision to continue using the uplink positioning reference signal configuration is made.

[0129] If the UE decides to continue using a saved uplink positioning reference signal configuration, at the time of this decision, the UE can start a timer associated with the uplink positioning reference signal configuration to time the uplink positioning reference signal configuration to be used. This reduces the situation where configuration resources remain occupied when the timer expires and the UE does not continue using the saved uplink positioning reference signal configuration, and facilitates further processing of the uplink positioning reference signal configuration when the timer expires.

[0130] For example, if a saved uplink positioning reference signal configuration is to be used continuously, starting the timer associated with the uplink positioning reference signal configuration may include the following: If the UE returns to an RRC-disconnected state and continues to use the saved uplink positioning reference signal configuration, the timer associated with the uplink positioning reference signal configuration is started.

[0131] In one embodiment, initiating a timer related to the uplink positioning reference signal configuration includes: To restart the timing of a timer that is currently paused; or To initiate the retiming of a timer that is currently stopped.

[0132] Here, restarting the timer's timing from the paused state corresponds to continuing the timing based on the timing value of the timer's previous pause.

[0133] In this context, initiating the retiming of a stopped timer is equivalent to restarting the timing based on the timer's initial value.

[0134] In one embodiment, the instruction information included in the RRC release message includes the following: First instruction information for instructing the aforementioned UE to continue using the uplink positioning reference signal configuration.

[0135] In one embodiment, the RRC release message can instruct the UE, through first instruction information, to continue using the uplink positioning reference signal configuration after entering an RRC disconnected state. If the RRC release message does not include the first instruction information, it means that the first network device is instructed not to continue using the uplink positioning reference signal configuration stored in the UE.

[0136] In another embodiment, the RRC release message may, through first instruction information, instruct the UE whether to continue using the uplink positioning reference signal configuration after entering an RRC disconnected state, and whether the UE continues to use the stored uplink positioning reference signal configuration is determined based on the specific content of the first instruction information.

[0137] In some embodiments, if the RRC release message explicitly or implicitly instructs the UE not to continue using the uplink positioning reference signal configuration after entering an RRC disconnected state, the UE may release the uplink positioning reference signal configuration.

[0138] In one embodiment, the method further includes: After receiving an RRC release message containing the first instruction information, the UE's RRC layer instructs the UE's Media Access Control (MAC) layer to start a timer.

[0139] Since the release of the uplink positioning reference signal configuration is related to the MAC layer timer, after the UE receives the first instruction information and decides to continue using the uplink positioning reference signal configuration, the UE's RRC layer generates an instruction, and after this instruction is transmitted to the MAC layer, the MAC layer starts a timer based on that instruction.

[0140] The RRC release message only needs to contain one first instruction, and the UE can automatically start the associated timer, resulting in low signaling overhead.

[0141] In one embodiment, the instruction information included in the RRC release message includes the following: Second instruction information instructing the UE to continue using the uplink positioning reference signal configuration; A third instruction piece instructs the start of a timer associated with the uplink positioning reference signal configuration, which is used to time the validity period of the uplink positioning reference signal configuration.

[0142] The UE's RRC layer receives the second instruction information and can decide whether or not to continue using the uplink positioning reference signal configuration based on the second instruction information.

[0143] Since the release of the uplink positioning reference signal configuration is related to the MAC layer timer, the timer is started in the UE's MAC layer based on the third instruction information.

[0144] The RRC release message may include a second instruction and a third instruction, respectively, instructing the UE to continue using the uplink positioning reference signal configuration and to start the associated timer.

[0145] The second and third instruction information may be contained by different bits in the RRC release message.

[0146] In one embodiment, the RRC release message may, through second instruction information, instruct the UE to continue using the uplink positioning reference signal configuration after entering an RRC disconnected state. If the RRC release message does not include the second instruction information, it means that the first network device is instructed not to continue using the uplink positioning reference signal configuration stored in the UE.

[0147] In one embodiment, the RRC release message can, through second instruction information, instruct the UE whether or not to continue using the uplink positioning reference signal configuration after entering an RRC disconnected state, and whether or not the UE continues to use the stored uplink positioning reference signal configuration is determined by the specific content of the second instruction information.

[0148] In some embodiments, the RRC release message explicitly or implicitly instructs the UE not to continue using the uplink positioning reference signal configuration after entering an RRC disconnected state, and the UE can release the uplink positioning reference signal configuration.

[0149] When the UE releases the uplink positioning reference signal configuration, the UE's MAC layer may also release the associated timers. Releasing the associated timers may include releasing the timer configuration information and / or clearing the timing value of the timer's last pause.

[0150] In some embodiments, the RRC release message instructs the UE to start the timer associated with the uplink positioning reference signal configuration through third instruction information. If the RRC release message does not include the third instruction information, it means that the first network device instructs the UE not to start the timer associated with the uplink positioning reference signal configuration.

[0151] In some embodiments, the RRC release message, through third instruction information, instructs the UE to start the timer associated with the uplink positioning reference signal configuration if the UE returns to an RRC disconnected state and continues to use the stored uplink positioning reference signal configuration.

[0152] In some embodiments, the third instruction information may also be used to indicate the timer's start mode. This start mode may include: starting continuous timing based on the timing value of the previous pause timing; or restarting timing based on the timer's initial value.

[0153] In one embodiment, referring to Figure 15, is a schematic diagram of a method for processing an uplink positioning reference signal configuration, which is performed by a first network device in a first cell, and this method includes the following steps.

[0154] Step S10: A Radio Resource Control (RRC) release message is sent, which allows a User Equipment (UE) that is in an RRC connected state to enter an RRC disconnected state, and the UE is used to continue using the stored uplink positioning reference signal configuration.

[0155] For example, the first network device may be any access device shown in Figure 1, such as an evolutionary access device (eNB), an access device employing a centralized-distributed architecture in a 5G system (gNB), or a transmission and reception point (TRP).

[0156] For example, the first network device has a first cell, which is the cell where the UE is currently located.

[0157] For example, the RRC release message instructs the UE to move from an RRC connected state to an RRC disconnected state. The RRC disconnected state includes the RRC idle state and / or the RRC inactive state.

[0158] Exemplary, the uplink positioning reference signal configuration may include at least one of the following: Uplink positioning reference signal resource configuration: At least the transmission time and frequency domain resources for the terminal to transmit the uplink positioning reference signal; Uplink positioning reference signal measurement reporting configuration: The terminal must at least indicate the transmission time and frequency domain resources for reporting the measurement results; Timing configuration: Used to indicate the validity period of the uplink positioning reference signal configuration, this timing configuration includes, but is not limited to, the value of the time adjustment timer (TAT); Area configuration: Indicates the effective area of ​​the uplink positioning reference signal configuration.

[0159] For example, the instruction information included in the RRC release message may instruct the UE to continue using the uplink positioning reference signal configuration stored in the UE.

[0160] For example, the instruction information included in the RRC release message may include a first instruction, and the instruction information may further include a second instruction and a third instruction.

[0161] For example, pre-configured information may be included (or carried) by a pre-configured field, i.e., the instruction information included in the RRC release message includes a pre-configured field, and the information included by the pre-configured field indicates whether the UE will continue to use the stored uplink positioning reference signal configuration.

[0162] For example, the RRC release message is used to instruct the UE to continue using the uplink positioning reference signal configuration stored therein.

[0163] After receiving an RRC release message, the UE may transition from an RRC connected state to an RRC disconnected state based on the RRC release message, and the UE may disconnect the RRC connection with the network device. At the same time, the UE may decide whether to continue using the stored uplink positioning reference signal configuration based on the instruction information contained in the RRC release message. The UE decides to continue using the stored uplink positioning reference signal configuration based on the instruction information contained in the RRC release message. If the RRC release message indicates that the stored uplink positioning reference signal configuration should be continued, the UE transmits an uplink positioning reference signal based on the stored uplink positioning reference signal configuration.

[0164] In another embodiment, the RRC release message includes: First instruction information: Used to instruct the UE to use the uplink positioning reference signal configuration.

[0165] Since the release of the uplink positioning reference signal configuration is related to the MAC layer timer, after the UE receives the initial instruction information and decides to continue using the uplink positioning reference signal configuration, the UE's RRC layer generates an instruction, and when this instruction is transmitted to the MAC layer, the MAC layer starts a timer based on that instruction.

[0166] The RRC release message only needs to contain one first instruction, and the UE can automatically start the associated timer, resulting in low signaling overhead.

[0167] In another embodiment, the RRC release message includes: Second instruction information: Used to instruct the UE to continue using the uplink positioning reference signal configuration; A third instruction piece instructs the start of a timer associated with the uplink positioning reference signal configuration, which is used to time the validity period of the uplink positioning reference signal configuration.

[0168] The UE's RRC layer receives the second instruction information and, based on that information, decides whether to continue using the uplink positioning reference signal configuration.

[0169] Since the release of the uplink positioning reference signal configuration is related to the MAC layer timer, the MAC layer of the UE starts the timer based on the third instruction information.

[0170] The RRC release message may include a second and a third instruction, respectively, instructing the UE to continue using the uplink positioning reference signal configuration and to start the associated timers.

[0171] The second and third instruction information may be contained by different bits in the RRC release message.

[0172] In one embodiment, the RRC release message, through second instruction information, instructs the UE to continue using the uplink positioning reference signal configuration after entering an RRC disconnected state. If the RRC release message does not include the second instruction information, it means that the first network device is instructed not to continue using the uplink positioning reference signal configuration stored in the UE.

[0173] In one embodiment, the RRC release message, through second instruction information, indicates to the UE whether to continue using the uplink positioning reference signal configuration after transitioning to an RRC disconnected state. Whether the UE continues to use the stored uplink positioning reference signal configuration is determined by the specific content of the second instruction information.

[0174] In some embodiments, the RRC release message explicitly or implicitly instructs the UE not to continue using the uplink positioning reference signal configuration after entering an RRC disconnected state, and the UE can release the uplink positioning reference signal configuration.

[0175] When the UE releases the uplink positioning reference signal configuration, the UE's MAC layer may also release the associated timers. Releasing the associated timers may include releasing the timer configuration information and / or clearing the timing values ​​of the previous timer pause.

[0176] In some embodiments, the RRC release message instructs the UE to start a timer associated with the uplink positioning reference signal configuration through third instruction information. If the RRC release message does not include third instruction information, it means that the first network device instructs the UE not to start a timer associated with the uplink positioning reference signal configuration.

[0177] In some embodiments, the RRC release message, through third instruction information, instructs the UE to start the timer associated with the uplink positioning reference signal configuration if the UE returns to an RRC disconnected state and continues to use the stored uplink positioning reference signal configuration.

[0178] In some embodiments, the third instruction information may also be used to indicate the timer start mode. This start mode may include the start of continuous timing based on the timing value of the previous pause, or the restart of timing based on the timer's initial value.

[0179] In another embodiment, referring to Figure 16, is a schematic diagram of a method for processing an uplink positioning reference signal configuration, which is performed by a first network device in a first cell, and this method further includes the following steps.

[0180] Step S20: If the UE in the RRC connected state hands over from the first cell to the second cell, and the UE saves the uplink position reference signal configuration for the RRC disconnected state, a fourth instruction is sent to the second network device. Here, the fourth instruction instructs the UE to save the uplink position reference signal configuration for the RRC disconnected state.

[0181] For example, the first cell is the source cell of the UE, and the second cell is the target cell.

[0182] For example, the second cell is a cell within the effective region of the uplink positioning reference signal configuration in the RRC-disconnected state.

[0183] After a UE in RRC connection state performs a cell handover, the UE continues to store the uplink positioning reference signal configuration because the handed-over target cell is within range. To make it easier for a second network device to subsequently know that the uplink positioning reference signal configuration is stored in the UE, the first network device can notify the second network device through any message during the cell handover process.

[0184] For example, the fourth instruction information is included in the cell handover message.

[0185] In some embodiments, any message in the handover process may also include: a context request message for the second network device to obtain the UE context from the first network device.

[0186] In another embodiment, referring to Figure 17, is a schematic diagram of a method for processing an uplink positioning reference signal configuration, which is performed by a second network device in a second cell and includes the following steps.

[0187] Step S1: Receive fourth instruction information transmitted from the first network device of the first cell. Here, the fourth instruction information is used to instruct the RRC-connected UE, which has been handed over from the first cell to the second cell, to save the uplink position reference signal configuration for the RRC-disconnected state.

[0188] For example, the second network device may be any access device shown in Figure 1, such as an evolutionary access device (eNB), an access device employing a centralized-distributed architecture in a 5G system (gNB), or a transmit / receive point (TRP).

[0189] For example, the first cell is the source cell of the UE, and the second cell is the target cell.

[0190] For example, the second cell is a cell within the effective range of the uplink positioning reference signal configuration when the RRC is not connected.

[0191] After a UE in RRC connection state performs a cell handover, the RRC connection state continues to store the uplink positioning reference signal configuration because the handed-over target cell is within range, and the second network device can then know that the uplink positioning reference signal configuration is stored in the UE by receiving the fourth instruction information, and the second network device can also know this by receiving any message transmitted from the first network device during the cell handover process.

[0192] For example, the fourth instruction information is included in the cell handover message.

[0193] In some embodiments, any messages in the handover process may include context request messages for the second network device to obtain the UE context from the first network device.

[0194] Exemplary, the uplink positioning reference signal configuration may include at least one of the following: Uplink positioning reference signal resource configuration: Indicates at least the transmission time and frequency domain resources for the terminal to transmit the uplink positioning reference signal; Uplink positioning reference signal measurement reporting configuration: The terminal must at least indicate the transmission time and frequency domain resources for reporting the measurement results; Timing configuration: Used to indicate the validity period of the uplink positioning reference signal configuration. This timing configuration includes, but is not limited to, the value of the Time Alignment Timer (TAT); Area configuration: Indicates the effective area of ​​the uplink positioning reference signal configuration.

[0195] In some embodiments, the method further includes: The second network device sends an RRC release message to the UE.

[0196] The RRC release message is used to enable the UE to enter an RRC disconnected state and to continue using the stored uplink positioning reference signal configuration.

[0197] For example, an RRC release message sent by a second network device may include the following: First instruction information: Used to instruct the UE to use the uplink positioning reference signal configuration.

[0198] The RRC release message has the advantage of low signaling overhead because it only needs to contain one first instruction, and the UE can automatically start the associated timer.

[0199] In one embodiment, the RRC release message, through first instruction information, instructs the UE to continue using the uplink positioning reference signal configuration after entering an RRC disconnected state. If the RRC release message does not include the first instruction information, it means that the second network device instructs the UE not to continue using the uplink positioning reference signal configuration stored therein.

[0200] In another embodiment, the RRC release message, through first instruction information, instructs the UE whether to continue using the uplink position reference signal configuration after entering an RRC disconnected state, and whether to continue using the stored uplink positioning reference signal configuration is determined based on the specific content of the first instruction information.

[0201] In some embodiments, if the RRC release message explicitly or implicitly instructs the UE not to continue using the uplink positioning reference signal configuration after entering an RRC disconnected state, the UE may release the uplink positioning reference signal configuration.

[0202] In another embodiment, the RRC release message includes: Second instruction information: Used to instruct the UE to continue using the uplink positioning reference signal configuration; Third instruction information: Used to instruct the start of the timer associated with the uplink positioning reference signal configuration.

[0203] The UE's RRC layer receives the second instruction information and can decide whether to continue using the uplink positioning reference signal configuration based on the second instruction information.

[0204] Since the release of the uplink positioning reference signal configuration is related to the MAC layer timer, the MAC layer of the UE starts the timer based on the third instruction information.

[0205] The RRC release message may include a second instruction and a third instruction, respectively, instructing the UE to continue using the uplink positioning reference signal configuration and to start the associated timer.

[0206] The second and third instruction information may be contained by different bits in the RRC release message.

[0207] In one embodiment, the RRC release message may, through second instruction information, instruct the UE to continue using the uplink positioning reference signal configuration after entering an RRC disconnected state. If the RRC release message does not include the second instruction information, it means that the second network device is instructed not to continue using the uplink positioning reference signal configuration stored in the UE.

[0208] In one embodiment, the RRC release message can, through second instruction information, instruct the UE whether or not to continue using the uplink positioning reference signal configuration after entering an RRC disconnected state, and whether or not the UE continues to use the stored uplink positioning reference signal configuration is determined by the specific content of the second instruction information.

[0209] In some embodiments, the RRC release message explicitly or implicitly indicates to the UE that it will not continue to use the uplink positioning reference signal configuration after entering an RRC disconnected state, and the UE can release the uplink positioning reference signal configuration.

[0210] When the UE releases the uplink positioning reference signal configuration, the UE's MAC layer may also release the associated timers. Releasing the associated timers here involves releasing the timer configuration information and / or clearing the timer's last pause timing value.

[0211] In some embodiments, the RRC release message instructs the UE to start the timer associated with the uplink positioning reference signal configuration through third instruction information. If the RRC release message does not include the third instruction information, it means that the first network device instructs the UE not to start the timer associated with the uplink positioning reference signal configuration.

[0212] In some embodiments, the RRC release message, through third instruction information, instructs the UE to start the timer associated with the uplink positioning reference signal configuration if the UE returns to an RRC disconnected state and continues to use the stored uplink positioning reference signal configuration.

[0213] In some embodiments, the third instruction information may also be used to indicate the timer's start mode. This start mode includes: starting continuous timing based on the timing value of the previous pause timing; or restarting timing based on the timer's initial value.

[0214] In another embodiment, referring to Figure 18, a schematic diagram of a method for processing an uplink positioning reference signal configuration is disclosed, the method being performed by a wireless communication system, the wireless communication system including user equipment (UE), and the method comprising the following steps:

[0215] Step A: The UE releases or saves the uplink positioning reference signal configuration based on a pre-configured rule, where the uplink positioning reference signal configuration is used for uplink positioning when the UE is in an RRC-disconnected state.

[0216] Exemplary, the user equipment (UE) may be any communication device shown in Figure 1, specifically a mobile phone, tablet computer, wearable device, in-vehicle device, smart home device, smart office device, and / or flight device.

[0217] Before performing step A, this method further includes: The system receives the uplink positioning reference signal configuration transmitted from the first network device.

[0218] For example, receiving an uplink positioning reference signal configuration transmitted from a first network device includes: The UE receives an RRC message instructing the UE to move from an RRC connected state to an RRC disconnected state, where the RRC message includes an uplink positioning reference signal configuration.

[0219] For example, a UE receives an RRC release message that instructs the UE to move from an RRC connected state to an RRC disconnected state. This RRC disconnected state includes the RRC idle state and / or the RRC inactive state.

[0220] The uplink positioning reference signal configuration may include at least one of the following: Uplink positioning reference signal resource configuration: Indicates at least the transmission time and frequency domain resources for the terminal to transmit the uplink positioning reference signal; Uplink positioning reference signal measurement reporting configuration: The terminal must at least indicate the transmission time and frequency domain resources for reporting the measurement results; Timing configuration: Used to indicate the validity period of the uplink positioning reference signal. This timing configuration includes, but is not limited to, the value of the Time Adjustment Time (TAT); Area configuration: Indicates the effective area of ​​the uplink positioning reference signal configuration.

[0221] Exemplary, the pre-configuration rules may be any predefined rules. The pre-configuration rules may be agreed upon by a protocol or indicated by uplink positioning reference signal configuration information. For example, the uplink positioning reference signal configuration may further include release rule configurations for the uplink positioning reference signal configuration.

[0222] In some embodiments, releasing or saving the uplink positioning reference signal configuration based on pre-configured rules may include: If a release event that satisfies the release rule configuration is detected, the uplink positioning reference signal configuration is released; otherwise, the uplink positioning reference signal configuration is kept stored.

[0223] Furthermore, exemplarily, releasing or saving the uplink positioning reference signal configuration based on pre-configured rules may include the following: Continue saving the uplink positioning reference signal configuration when re-selecting a cell; and / or, When the UE restores RRC connectivity with the current service cell, continue to preserve the uplink positioning reference signal configuration; and / or, If the UE's current location is within the valid range of the uplink positioning reference signal configuration, continue to save the uplink positioning reference signal configuration; and / or, If the UE moves outside the effective range of the uplink positioning reference signal configuration, release the uplink positioning reference signal configuration.

[0224] After the UR enters a disconnected state from a connected state, it may then enter a connected state again from a disconnected state. If the UE has previously stored an uplink positioning reference signal configuration, the stored uplink positioning reference signal configuration can be used continuously, reducing the request for uplink positioning reference signal configurations that the UE transmits to the first network device, thereby reducing signaling overhead.

[0225] In other words, in embodiments of the present disclosure, the UE can release or store the uplink positioning reference signal configuration used in the RRC-disconnected state based on pre-configured rules. This reduces the occurrence of releases when the UE does not need to release the uplink positioning reference signal configuration for the RRC-disconnected state, reduces the re-requests for the uplink positioning reference signal configuration from the first network device due to excessive releases by the UE, and reduces signaling overhead.

[0226] In one embodiment, the uplink position reference signal configuration when the UE is in an RRC-disconnected state has an effective region.

[0227] Within the effective region, the uplink position reference signal configuration is active, and outside the effective region, the uplink position reference signal configuration is inactive.

[0228] For example, the effective area can contain one or more cells.

[0229] The region configuration indicating the effective area may include the following: Area identifiers: Different areas have different area identifiers, and these area identifiers may include geographical area identifiers such as tracking area identifiers and / or wireless access notification area identifiers.

[0230] Cell identifier: Indicates a cell included in the valid area. This cell identifier can be included by a cell list.

[0231] In one embodiment, the effective region of the uplink positioning reference signal configuration may be a connected continuous region.

[0232] In one embodiment, if the effective area includes multiple cells, these multiple cells are distributed continuously or adjacently.

[0233] In another embodiment, referring to Figure 19, a schematic diagram of a method for processing an uplink positioning reference signal configuration is disclosed, the method being performed by a wireless communication system, the wireless communication system further including a first network device, and the method further includes the following steps.

[0234] Step B: The first network device sends an RRC recovery message or an RRC establishment message.

[0235] Step C:UE receives an RRC recovery message or an RRC establishment message and saves the uplink positioning reference signal configuration.

[0236] The first network device may be any access device shown in Figure 1, such as an evolutionary access device (eNB), an access device using a centralized-distributed architecture in a 5G system (gNB), or a transmission and reception point (TRP).

[0237] The Radio Resource Control (RRC) recovery message (RRC resume message) is used to instruct a UE that is in an RRC inactive state to enter an RRC connected state.

[0238] The Radio Resource Control (RRC) establishment message (RRC setup message) is used to instruct a UE (User Environment) that is in an RRC connection state to enter the RRC connection state.

[0239] For example, the RRC layer of a terminal receives a Radio Resource Control (RRC) recovery message (RRC resume message) sent from a first network device, and the RRC layer of a terminal receives a Radio Resource Control (RRC) setup message (RRC setup message) sent from the first network device.

[0240] After transitioning from an RRC-disconnected state to an RRC-connected state, the UE continues to store the uplink positioning reference signal configuration even while in the RRC-disconnected state. This allows the UE to transmit the uplink positioning reference signal based on the stored uplink positioning reference signal configuration without having to request the configuration again when it enters the RRC-disconnected state again.

[0241] In another embodiment, referring to Figure 20, a schematic diagram of a method for processing an uplink positioning reference signal configuration is disclosed, the method being performed by a wireless communication system, the wireless communication system further including a first network device, and the method further includes the following steps.

[0242] Step D: The first network device sends an RRC release message.

[0243] Step E:UE receives the RRC release message and continues to use the saved uplink position reference signal configuration.

[0244] For example, the RRC release message instructs the UE to move from an RRC connected state to an RRC disconnected state. The RRC disconnected state includes the RRC idle state and / or the RRC inactive state.

[0245] For example, the instruction information included in the RRC release message may instruct the UE to continue using the stored uplink positioning reference signal configuration.

[0246] For example, the instruction information included in the RRC release message may include a first instruction; or the instruction information included in the RRC release message may include message content such as a second instruction and a third instruction.

[0247] Exemplarily, the message content can be included (or carried) by a preset field, that is, the message content of the RRC release message includes a preset field, and the information content included by the preset field is information content indicating whether the UE continues to use the saved uplink positioning reference signal configuration.

[0248] Exemplarily, the RRC release message is used to instruct the UE to continue using the uplink positioning reference signal configuration saved in the UE.

[0249] After receiving the RRC release message, the UE enters the RRC idle state from the RRC connected state based on the RRC release message, and the UE can disconnect the RRC connection with the first network device. At the same time, the UE can determine whether to continue using the saved uplink positioning reference signal configuration based on the indication information included in the RRC release message. The UE determines to continue using the saved uplink positioning reference signal configuration based on the indication information included in the RRC release message. If the RRC release message continues to use the saved uplink positioning reference signal configuration, the UE transmits an uplink positioning reference signal based on the saved uplink positioning reference signal configuration.

[0250] In another embodiment, the RRC release message includes the following: First indication information: used to instruct the UE to use the uplink positioning reference signal configuration.

[0251] In one embodiment, the RRC release message instructs the UE to continue using the uplink positioning reference signal configuration after entering the RRC idle state through the first indication information. At this time, if the RRC release message does not include the first indication information, it means that the first network device instructs the UE not to continue using the uplink positioning reference signal configuration saved in the UE.

[0252] In another embodiment, when the RRC release message indicates whether to continue using the uplink positioning reference signal configuration after the UE enters the RRC idle state through the first indication information, whether the UE continues to use the saved uplink positioning reference signal configuration is determined based on the specific content of the first indication information.

[0253] In some embodiments, when the RRC release message explicitly or implicitly instructs the UE not to continue using the uplink positioning reference signal configuration after entering the RRC idle state, the UE can release the uplink positioning reference signal configuration.

[0254] In one embodiment, the method further includes the following: After the UE receives the RRC release message including the first indication information, the RRC layer of the UE instructs the media access control (MAC) layer of the UE to start a timer.

[0255] Since the release of the uplink positioning reference signal configuration is related to the timer of the MAC layer, after receiving the first indication information and the UE determines to continue using the uplink positioning reference signal configuration, the RRC layer of the UE generates an instruction. After the instruction is transmitted to the MAC layer, the MAC layer starts the timer based on the instruction.

[0256] The RRC release message only needs to include the first indication information once. Since the UE can automatically start the related timer, it has the characteristic of low signaling overhead.

[0257] In another embodiment, the RRC release message includes the following: Second indication information: instructing the UE to continue using the uplink positioning reference signal configuration; Third indication information: instructing to start a timer related to the uplink positioning reference signal configuration.

[0258] Since the release of the uplink positioning reference signal configuration is related to the MAC layer timer, the MAC layer of the UE starts the timer based on the third instruction information.

[0259] The UE's RRC layer receives the second instruction information and can decide whether to continue using the uplink positioning reference signal configuration based on the second instruction information.

[0260] Since the release of the uplink positioning reference signal configuration is related to the MAC layer timer, the MAC layer of the UE starts the timer based on third instruction information.

[0261] The RRC release message may include a second instruction and a third instruction, respectively, instructing the UE to continue using the uplink positioning reference signal configuration and to start the associated timer.

[0262] The second and third instruction information may be contained by different bits in the RRC release message.

[0263] In one embodiment, the RRC release message may, through second instruction information, instruct the UE to continue using the uplink positioning reference signal configuration after entering an RRC disconnected state. If the RRC release message does not include the second instruction information, it means that the first network device is instructed not to continue using the uplink positioning reference signal configuration stored in the UE.

[0264] In one embodiment, the RRC release message, through second instruction information, instructs the UE whether to continue using the uplink positioning reference signal configuration after entering an RRC disconnected state, and whether the UE continues to use the stored uplink positioning reference signal configuration is determined by the specific content of the second instruction information.

[0265] In some embodiments, if the RRC release message explicitly or implicitly indicates to the UE that it will not continue to use the uplink positioning reference signal configuration after entering an RRC disconnected state, the UE may release the uplink positioning reference signal configuration.

[0266] When the UE releases the uplink positioning reference signal configuration, the UE's MAC layer may also release the associated timers. Releasing the associated timers may include releasing the timer configuration information and / or clearing the timer's last pause timing value.

[0267] In some embodiments, the RRC release message instructs the UE to start the timer associated with the uplink positioning reference signal configuration through third instruction information. If the RRC release message does not include the third instruction information, it means that the first network device instructs the UE not to start the timer associated with the uplink positioning reference signal configuration.

[0268] In some embodiments, the RRC release message, through third instruction information, instructs the UE to start the timer associated with the uplink positioning reference signal configuration if the UE returns to an RRC disconnected state and continues to use the stored uplink positioning reference signal configuration.

[0269] In some embodiments, the third instruction information may also be used to indicate the timer's start mode. The start mode may include: starting continuous timing based on the timing value of the previous pause timing; or restarting timing based on the timer's initial value.

[0270] In another embodiment, referring to Figure 21, a schematic diagram of a method for processing an uplink positioning reference signal configuration is disclosed, the method being performed by a wireless communication system, the wireless communication system further including a second network device, the method further including the following steps.

[0271] Step F: When the UE in the RRC connected state handovers from the first cell to the second cell and the UE saves the uplink positioning reference signal configuration for the RRC idle state, the first network device transmits fourth indication information to the second network device, where the fourth indication information indicates that the UE saves the uplink positioning reference signal configuration for the RRC idle state.

[0272] Exemplarily, the second network device may be any access device shown in FIG. 1, such as an evolved access device (eNB), an access device (gNB) adopting a centralized distributed architecture in a 5G system, a transmission and reception point (TRP), etc.

[0273] Exemplarily, the first network device has a first cell, and the first cell is the cell where the UE is currently located.

[0274] Exemplarily, the first cell is the source cell of the UE, and the second cell is the target cell.

[0275] Exemplarily, the second cell is a cell within the valid range of the uplink positioning reference signal configuration in the RRC idle state.

[0276] After the UE in the RRC connected state executes a cell handover, since the target cell to which the RRC connection state has been handed over is a cell within the valid range, the UE continues to save the uplink positioning reference signal configuration. For the second network device to easily know that the uplink positioning reference signal configuration is saved in the UE, the first network device notifies the second network device through any message during the cell handover process.

[0277] Exemplarily, the fourth indication information is included in the cell handover message.

[0278] In some embodiments, any message in the handover process may also include: a context request message for a second network device to obtain a UE context from the first network device.

[0279] In another embodiment, a method for processing an uplink positioning reference signal configuration is also provided, which is performed by a wireless communication system, and the method further includes: The second network device receives fourth instruction information transmitted by the first network device of the first cell, and this fourth instruction information is used to instruct the RRC-connected UE, which has handed over from the first cell to the second cell, to save the uplink positioning reference signal configuration for the RRC-disconnected state.

[0280] In another embodiment, referring to Figure 22, a schematic diagram of a processing device for an uplink positioning reference signal configuration is disclosed, the device including: Processing module 1: Configured to release or save an uplink positioning reference signal configuration based on pre-configured rules, the uplink positioning reference signal configuration is used for uplink positioning when the UE is in an RRC disconnected state.

[0281] In another embodiment, referring to Figure 23, another schematic diagram of a processing unit for an uplink positioning reference signal configuration is disclosed, which includes: Transmitter module 2 is configured to send a message to a user equipment (UE) that causes the UE, which is in an RRC-disconnected state, to enter an RRC-connected state, and this message is used by the UE to save the uplink positioning reference signal configuration.

[0282] In another embodiment, a communication device is also disclosed, which includes a processor, a transceiver, memory, and an executable program stored in the memory and executable by the processor, wherein when the processor executes the executable program, it performs a method for processing an uplink positioning reference signal configuration provided in any of the above embodiments.

[0285] When the UE's RRC layer receives a Radio Resource Control (RRC) establishment message (RRC setup message) sent from the first network device and is used to instruct the RRC-connected UE to enter the RRC-connected state.

[0286] However, with respect to the uplink positioning reference signal configuration related to the effective area, the UE does not necessarily need to release the uplink positioning reference signal configuration after performing cell reselection.

[0287] If the UE receives an RRC resume message or an RRC setup message, the UE may stop sending SRS signals without releasing the SRS configuration.

[0288] In one embodiment, the first network device configures an uplink positioning reference signal configuration related to the effective area on the UE, and the release condition for the uplink positioning reference signal configuration related to the effective area includes at least one of the following: The UE performs cell reselection, and the target cell reselected by the UE is not within the valid area of ​​the uplink positioning reference signal configuration; The UE receives an RRC resume message, saves the uplink positioning reference signal configuration associated with the active area, and the Medium Access Control (MAC) layer within the UE stops the timer associated with the uplink positioning reference signal configuration; The UE receives an RRC setup message, saves the uplink positioning reference signal configuration associated with the active area, and the Media Access Control (MAC) layer in the UE stops the timer associated with the uplink positioning reference signal configuration; The UE performs a cell handover and releases the uplink positioning reference signal configuration associated with the effective area; The UE receives an RRC release message instructing it to use a previously saved uplink positioning reference signal configuration, and the UE's Medium Access Control (MAC) layer starts the timer associated with the uplink positioning reference signal configuration.

[0289] One embodiment discloses a method for processing an uplink positioning reference signal configuration related to the effective area of ​​a UE, which includes: The UE saves or releases the uplink positioning reference signal configuration associated with the effective area.

[0290] In one embodiment, a first network device configures an uplink positioning reference signal configuration associated with the active area on the UE. When the UE is in an RRC-disconnected state and performs cell reselection, and the target cell for cell reselection is located outside the active area, the UE releases the uplink positioning reference signal configuration, and the UE's Medium Access Control (MAC) layer stops the timer associated with the uplink positioning reference signal configuration.

[0291] In one embodiment, the effective region is indicated by PCIs in the Physical Cell Identifier (PCI) list, e.g., PCI1, PCI2 and / or PCI3, and the UE performs cell reselection. If the PCI of the target cell selected by the UE is PCI5, the UE releases the uplink positioning reference signal configuration.

[0292] In one embodiment, a first network device sets an uplink positioning reference signal configuration related to the active area on the UE, the UE receives a radio resource control setup (RRC setup) message, the UE saves the uplink positioning reference signal configuration related to the active area, and the UE's Medium Access Control (MAC) layer stops a timer related to the uplink positioning reference signal configuration.

[0294] In one embodiment, the first network device sets an uplink positioning reference signal configuration associated with the active area to the UE, and when the UE performs a cell handover, the UE releases the uplink positioning reference signal configuration associated with the active area.

[0295] In one embodiment, the first network device sets an uplink positioning reference signal configuration associated with the effective area to the UE, and when the UE performs a cell handover and the target cell is outside the effective area, the UE releases the uplink positioning reference signal configuration associated with the effective area.

[0296] In one embodiment, the UE receives an RRC resume message, which instructs the UE to continue using a stored uplink positioning reference signal configuration associated with the valid area. The UE then continues to use the stored uplink positioning reference signal configuration and transmits an uplink positioning reference signal based on the stored uplink positioning reference signal configuration.

[0297] In one embodiment, the Medium Access Control (MAC) layer of the UE starts a timer related to the uplink positioning reference signal configuration.
