[0001] This application relates to the field of communication technologies, and more specifically, to communication methods, terminal devices, access network devices, and core network devices.

Background Art

[0002] In the prior art, there are many problems with uplink positioning. When the terminal device performs cell reselection or the validity criterion fails, the transmission of the first signal for positioning is stopped and the configuration of the first signal is released, thereby causing interruption of positioning. The first signal may include, for example, a sounding reference signal for positioning (SRS-Pos). If positioning is to be continued, the terminal device needs to restore the connection with the network, and thereby the network provides a new configuration of the first signal to the terminal device, which causes additional power consumption and signaling overhead.

[0121] It should be understood that all or some of the functions of the communication equipment in this application may be implemented by software functions running on the hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform). Positioning technology

[0122] In wireless communication systems, positioning of communication devices can be achieved based on positioning technology.

[0123] Positioning technologies can be divided into uplink positioning, downlink positioning, and combined uplink / downlink positioning. Regardless of the positioning technology, a reference signal is required. The reference signal may be, for example, a sounding reference signal (SRS). When performing uplink positioning, a serving cell can transmit SRS-Pos configuration information. Terminal devices can transmit SRS-Pos based on the SRS-Pos configuration information. Access network equipment corresponding to the serving cell or adjacent cells can receive the SRS-Pos. Based on the received SRS-Pos, the access network equipment can estimate information such as power, time delay, or angle, and either perform positioning calculations using this information to obtain the user's location information or report this information to core network equipment (e.g., LMF). The core network equipment can perform positioning calculations based on the reported information to obtain the terminal device's location information.

[0124] SRS-Pos configuration information can be configured using the higher-level parameter "SRS-Config" and is associated with the dedicated uplink bandwidth part (ULBWP) of a specific cell. SRS-Pos configuration information may include, for example, information about the SRS-Pos resource set (e.g., bearered in the SRS-PosResourceSet field) and information about the SRS-Pos resource (e.g., bearered in the SRS-PosResource field). SRS-Pos resource set information may include, for example, one or more of the following: identifier of the SRS resource set for positioning (srs-sResourceSetId), list of identifiers for the SRS resource for positioning (srs-PosResourceIdList), resource type (resourceType), offset (e.g., including fields alpha and p0), and reference RS path loss (pathlossReferenceRS-Pos). The information for an SRS-Pos resource may include, for example, one or more of the following: an identifier for the SRS resource used for positioning (srs-PosResourceId), the configuration of the transmission comb (transmissionComb), the time-domain position of the SRS resource used for positioning (resourceMapping (e.g., including the fields startPosition and nrofSymbols)), the frequency-domain position (freqDomainShift), frequency-hopping configuration-related parameters for the SRS resource used for positioning (freqHopping(c-SRS)), group frequency-hopping or sequence frequency-hopping instruction (groupOrSequenceHopping), the type of the SRS resource used for positioning (resourceType), the sequence identifier for initialization (sequenceId), and the spatial relationship between the reference RS and the target SRS (spatialRelationInfoPos).

[0125] With technological advancements, mobile devices and assets are becoming increasingly common in flexible production. Consequently, the demand for real-time location data in production processes is also increasing. As such, positioning is crucial for factory control applications. Factory control applications may include, for example, warehousing and logistics flows, autonomous driving systems, and vehicle management. In an ideal scenario, all relevant goods and products can be continuously tracked from receipt to availability. The tracking process can provide optimization of relevant contextual information necessary for real-time control, material flow, and subsequent production processes. For example, an autonomous driving system can independently extract parts from a warehouse and transport them to assembly units in the workshop. Also, for example, as part of a flexible vehicle management system, an autonomous driving system can constantly determine its own position, move quickly, and constantly interact with its environment. Furthermore, for example, production machinery and assembly units and their given states can be seamlessly monitored. Monitoring, along with positioning relevant objects such as tools and workpieces, enables rapid adaptation to environmental changes, resulting in more flexible and autonomous production control that can adapt to new situations at any time. Furthermore, wireless positioning based on human interfaces such as augmented reality (AR) and virtual reality (VR) is also possible.

[0126] In addition to the demand for positioning, power consumption is also becoming a significant factor in the positioning process. Specifically, low-power, high-precision positioning is essential for industrial applications. For low-power Internet of Things devices, the total energy required at any given time includes energy for positioning (which varies depending on the positioning method used), energy for communication and synchronization, and power consumption due to unpredictable factors, taking into account extraneous losses. Power consumption may include one or more of the power used for safety, power management, microcontrollers, and battery self-discharge. Examples of target applications for low-power, high-precision positioning include at least one of asset tracking, vehicle tracking, and tool tracking in process automation.

[0127] For low-power, high-precision positioning, the positioning requirements vary across different use cases. Table 1 shows examples of demand use cases for low-power, high-precision positioning. [Table 1]

[0128] In related technologies, power consumption can be high during uplink positioning. For example, for uplink positioning of terminal equipment in a Radio Resource Control (RRC) inactive state (RRC_INACTIVE), SRS-Pos configuration information is carried to the RRC signaling of the serving cell (also called the cell corresponding to the serving RAN node) (e.g., RRC Connection Resource (RRCRelease) signaling). The SRS-Pos configuration is only valid when the terminal equipment is in the serving cell and the timing alignment timer is operating. That is, if the terminal equipment reselects a cell or the validity criteria fail, it stops transmitting SRS-Pos and releases the SRS-Pos configuration. The validity criteria can be determined based on the measurement of path loss. After releasing the SRS-Pos configuration, the terminal equipment cannot transmit SRS-Pos, which causes a positioning interruption. However, in some cases, positioning cannot be interrupted, meaning that the terminal device still needs to transmit SRS-Pos after releasing the SRS-Pos configuration. For example, the use case defined in TS22.104 requires the terminal device to periodically transmit SRS-Pos. In these situations, the terminal device needs to reconnect to the network after cell reselection so that the LMF can re-request the terminal device's SRS-Pos configuration information. Furthermore, network equipment needs to provide the terminal device with a new SRS-Pos configuration, which incurs extra power consumption and signaling overhead. In particular, for mobile terminal devices that periodically perform cell reselection, the above process incurs a large amount of power consumption and signaling overhead, making it difficult to meet low power consumption requirements.

[0129] Figure 2 is a flowchart of a communication method according to an embodiment of the present invention, which is intended to solve the above problem. The method shown in Figure 2 can be executed from access network equipment and terminal equipment. The method shown in Figure 2 may include step S210.

[0130] In step S210, the terminal device receives the first configuration information. In response, the access network device transmits the first configuration information.

[0131] The first configuration information may be related to the first domain and the first signal.

[0132] The first signal may be a positioning signal. For example, the first signal may be the positioning SRS, i.e., SRS-Pos.

[0133] The first region may contain multiple cells. In other words, the first configuration information may be related to multiple cells, or the first configuration information may be used to configure the first signal in multiple cells.

[0134] When a terminal device camps on to any cell in the first region, the first configuration information may be used to indicate the information that constitutes the first signal. The information that constitutes the first signal may be used to indicate, for example, the configuration information of the transmission resource for the first signal. That is, the first configuration information may be used to indicate the transmission resource for the first signal. The terminal device can transmit the first signal at the transmission resource indicated by the first configuration information. Taking SRS-Pos as an example, the first configuration information can realize a multi-cell SRS configuration, a cross-cell configuration, or a multi-cell SRS linked configuration, and the information that constitutes the first signal may include one or more of the above-mentioned parameters "SRS-Config".

[0135] One understandable point is that when a terminal device camps on to any cell in the first region, the terminal device can transmit a first signal based on the first configuration information, or the first configuration information may be used to construct the first signal. Alternatively, the first configuration information can realize the construction of the first signal for cells that are not currently camped on, that is, the first configuration information can realize cross-cell configuration. As one implementation, the terminal device can perform cell reselection in the first region. Before the terminal device performs cell reselection, the terminal device can transmit a first signal based on the first configuration information. After the terminal device performs cell reselection, that is, when the cell to which the terminal device camps on changes, the terminal device can still transmit a first signal based on the first configuration information.

[0136] One point that can be understood is that if the terminal device is within the first region, all of the first configuration information may be valid, that is, all of the first configuration information may be used to construct the first signal for positioning. Therefore, the first region may be called the positioning valid region (or abbreviated as the valid region).

[0137] As one implementation, the first configuration information may include information of the first region and information that constitutes the first signal. The information of the first region may include, for example, information of multiple cells in the first region. For example, the information of the first region may include the IDs of the multiple cells.

[0138] One understandable point is that, in the cell where the terminal device is currently camped on, it can transmit a first signal based on first configuration information. If the cell where the terminal device is camped on changes at a future point in time, the terminal device can still determine the first signal to be transmitted based on the first configuration information. In other words, the first configuration information can pre-configure the first signal. Based on the first configuration information, even if the cell where the terminal device is camped on changes, as long as the newly camped-on cell belongs to the first region, the terminal device can still transmit the first signal based on the first configuration information to achieve positioning. Therefore, when the cell where the terminal device is camped on changes, the terminal device does not need to establish a connection with the network device, nor does it need to perform signaling interaction with the network device to obtain the configuration information of the first signal, thereby reducing signaling and power consumption overhead. Furthermore, multiple cooperative configurations can be configured using the first configuration information, so the network device does not need to simultaneously monitor the first signal configurations of multiple cells, thereby simplifying the communication flow and improving communication efficiency.

[0139] In some embodiments, the first configuration information may be determined by an access network device corresponding to the cell to which the terminal device is currently camp-on. In other embodiments, the first configuration information may be determined by a core network device. In other words, the core network device can configure the first signals of terminal devices in a first region. For example, if the first configuration information is used to configure the transmission resources for the first signals, the core network device can allocate resources to each terminal device in the first region to transmit the first signals, thereby avoiding resource collisions caused by different first signals in the first region using the same resources.

[0140] Taking the first configuration information as an example, the method shown in Figure 3 may further include step S202. As shown in Figure 3, the method shown in Figure 3 can also be implemented by the core network equipment. The core network equipment may include a positioning server (e.g., LMF).

[0141] In step S202, the core network equipment determines the first configuration information.

[0142] Since the first region contains multiple cells, the core network can determine the first configuration information and achieve coordination of the configuration information of multiple cells, thereby avoiding collisions and configuration anomalies. For example, as described above, the first configuration information may be used to configure the transmission resources for the first signal. Therefore, the core network equipment can determine the transmission resources for the first signal and the first configuration information, enabling rational scheduling of resources within the first region of the core network equipment, thereby avoiding situations such as resource collisions within the first region.

[0143] After determining the first configuration information, the core network device can execute step S203. In step S203, the core network device transmits the first configuration information to the access network device. The access network device receives the first configuration information.

[0144] The above embodiment will be described in detail below, with reference to Figure 3, using the example that the first signal is an SRS for positioning.

[0145] The method shown in Figure 3 can be implemented using terminal equipment, first access network equipment, second access network equipment, and core network equipment. The method shown in Figure 3 may include steps S310 to S360.

[0146] Step S310: The first access network device transmits the first configuration information to the terminal device.

[0147] The cell corresponding to the first access network device may be a serving cell of a terminal device. That is, based on step S310, the network device corresponding to the serving cell can transmit the first configuration information to the terminal device. The first configuration information may include information of the first area and configuration information of the SRS.

[0148] In step S320, the core network device sends a measurement request to the access network device that is expected to receive the SRS. The measurement request can be sent via an NRPPa message.

[0149] Taking as an example that the access network equipment expected to receive the SRS includes a first access network equipment and a second access network equipment, step S320 may include steps S321 and S322. The second access network equipment may be an adjacent access network equipment, that is, the second access network equipment may be an access network equipment corresponding to an adjacent cell.

[0150] In step S321, the core network device sends a measurement request to the first access network device. In step S322, the core network device sends a measurement request to the second access network device.

[0151] Note that Figure 3 is merely an example, and the access network equipment expected to receive the SRS does not necessarily have to include the second access network equipment; it may include other access network equipment as well.

[0152] In step S330, based on the first configuration information, the terminal device transmits an SRS signal, and the access network device receives the SRS signal, thereby achieving positioning.

[0153] For example, if the access network equipment that is scheduled to receive the SRS includes a first access network device and a second access network device, step S330 may include steps S331 to S334.

[0154] Step S331, the terminal device transmits an SRS to the first access network device.

[0155] Step S332, the terminal device transmits an SRS to the second access network device.

[0156] In step S333, based on the received SRS, the first access network device determines the measurement result and transmits the measurement result to the core network device.

[0157] In step S334, based on the received SRS, the second access network device determines the measurement result and transmits the measurement result to the core network device.

[0158] In step S340, the terminal device performs cell reselection. After reselection, it camps on to the cell corresponding to the second access network device. The cell corresponding to the second access network is located within the first area.

[0159] In step S350, the core network equipment sends a measurement request to the access network equipment that is expected to receive the SRS. The measurement request can be sent via an NRPPa message.

[0160] Note that in step S350, the access network equipment scheduled to receive the SRS may be different from that in step S320. This is because, since the location of the terminal equipment has changed, the cell scheduled to receive the SRS may also change, and therefore the access network equipment corresponding to that cell may also change.

[0161] Step S350 may include step S351. In step S351, the core network device sends a measurement request to the second access network device. Step S350 may also include other steps, meaning the core network device can send measurement requests to other access network devices.

[0162] In step S360, based on the first configuration information, the terminal device transmits an SRS, and the access network devices (including, for example, serving access network devices and adjacent access network devices) receive the SRS and perform positioning.

[0163] For example, if the access network equipment that is scheduled to receive the SRS includes a second access network equipment, step S360 may include steps S361 and S362.

[0164] Step S361, the terminal device transmits an SRS to the second access network device.

[0165] In step S362, based on the received SRS, the second access network device determines the measurement result and transmits the measurement result to the core network device.

[0166] Furthermore, other access network devices can also receive the SRS; that is, the receiving end of the SRS may include other access network devices besides the second access network device. For example, the first access network device may also receive and measure the SRS. Which access network device specifically receives the SRS can be determined based on the recipient of the measurement request sent from the core network device in step S350.

[0167] In some embodiments, the method shown in Figure 3 may further include step S302. In step S302, the first access network device determines first configuration information. The first access network device is an access device corresponding to a serving cell, and therefore step S302 can determine first configuration information for the serving cell.

[0168] Furthermore, the steps performed by the first access network device or the second access network device described above can also be performed by the core network device. Specifically, the core network device may include a positioning server. For example, step S302 can be performed by the core network device. In some implementations, step S302 can be performed by the positioning server.

[0169] In some embodiments, the multiple cells in the first region may include a first cell and a second cell, and when a terminal device camps on to the first cell or the second cell, the information constituting the first signal may be the same. For example, during the UL positioning period, if the terminal device moves from the first cell to the second cell due to cell reselection, the terminal device can continue to transmit the first signal using the information that constituted the first signal when it was in the first cell, that is, it continues to multiplex the information that constituted the first signal before reselection.

[0170] Furthermore, the first and second cells may be cells of the same frequency or cells of different frequencies, and this application does not limit this.

[0171] One understandable point is that although the cell to which the terminal device camps on has already changed, the relative positional relationship between the terminal device and the network remains within a certain range. Therefore, the configuration information of the first signal before cell re-selection may still be applicable. In this case, the information that constituted the first signal can remain unchanged. Taking the embodiment shown in Figure 3 as an example, the terminal device can continue to configure the first signal in step S360 based on the information that constituted the first signal in step S330, thereby enabling the transmission of the first signal in S360.

[0172] As can be seen from this, when a terminal device performs cell reselection, the terminal device does not need to release the information that constituted the first signal before cell reselection. As mentioned above, after cell reselection, the information that constitutes the first signal may be the same as before cell reselection. Therefore, the terminal device can continue to transmit the first signal based on the information that constituted the first signal before cell reselection. It can be understood that this method can reduce the processing steps of the terminal device, thereby further reducing energy consumption.

[0173] In some embodiments, when a terminal device performs cell reselection, the terminal device may release the information that constituted the first signal before the cell reselection. When the terminal device camps on to a new cell, the terminal device can re-determine the information that constitutes the first signal based on the first configuration information. Selectably, the re-determined information that constitutes the first signal may be the same as that before the reselection. In this manner, the processing flow of the terminal device is similar to the processing flow in related technologies, thereby minimizing the changes to the terminal device of this application and enabling compatibility with the first signal configuration method of related technologies. It is understandable that, although the terminal device releases the information that constituted the first signal before cell reselection after cell reselection, the terminal device does not need to request the acquisition of new configuration information from the network, and can determine the new information that constitutes the first signal based on the first configuration information. Therefore, the method can still reduce signaling and power consumption overhead to some extent.

[0174] As described above, all cells in the first region can use the same information that constitutes the first signal. Considering that terminal devices move between cells, if different terminal devices in different cells constitute the same information that constitutes the first signal, these terminal devices using the same first signal configuration are located in the same cell, thereby causing serious interference to access network devices that detect the first signal. Even if these terminal devices using the same first signal configuration are located in different cells, the access network device that detects the first signal reports the detected first signal measurement and identifier to the positioning server. The positioning server does not know which measurement belongs to the same user during the positioning calculation, which causes a large error in the positioning calculation. In particular, the closer the distance between users using the same first signal configuration, the more difficult it is to overcome the positioning calculation error. This application proposes to solve the above problem with first instruction information. The first instruction information may be used to instruct a terminal device to continue using the previous first signal configuration when camping on to which cell or which cell. This technical solution is described in detail below.

[0175] In some embodiments, terminal equipment can receive first instruction information. Access network equipment can transmit first instruction information. The first instruction information may be used to indicate whether the information constituting the first signal is the same or different when the terminal equipment camps on to a first or second cell. In one implementation, the first instruction information can indicate whether the terminal equipment can continue to use the information that constituting the first signal when it previously camped on to the first cell when camping on to the second cell. If the first instruction information instructs the terminal equipment to camp on to the second cell, it can use the information that previously constituting the first signal, and when the terminal equipment performs cell reselection and reaches the second cell, it can multiplex the information that previously constituting the first signal. If the first instruction information instructs the terminal equipment to camp on to the second cell, it cannot use the information that previously constituting the first signal, and therefore, when the terminal equipment performs cell reselection and reaches the second cell, it cannot multiplex the information that previously constituting the first signal, and can determine new information constituting the first signal based on the ID and / or first configuration information of the second cell, for example.

[0176] Furthermore, for cells where the information constituting the first signal is unavailable before being instructed by the first instruction information, when a terminal device camps on to that cell, the information constituting the new first signal may be the same as the information constituting the first signal previously. This enables reuse of information configured within the first area and further improves the resource utilization rate of the first signal.

[0177] The following explanation will use the example that the first signal is SRS-Pos to illustrate the technical solution. When a terminal device reaches adjacent cell A or adjacent cell B after re-selection from serving cell 1, the access network device corresponding to the serving cell can configure, via first instruction information, whether or not to reuse the existing SRS-Pos configuration. The first instruction information can, for example, instruct the device to multiplex the existing SRS-Pos configuration when it reaches cell A after re-selection, and to perform SRS transmission based on the SRS-Pos configuration of cell B when it reaches cell B after re-selection.

[0178] One understandable point is that, for a certain adjacent cell (e.g., adjacent cell A), when camp-on is performed in that adjacent cell, the information previously used to constitute the first signal can be multiplexed and the first signal can continue to be constituted. However, for a certain adjacent cell (e.g., adjacent cell B), when camp-on is performed in that adjacent cell, the information previously used to constitute the first signal cannot be multiplexed and the first signal can continue to be constituted. This enables the separation of the first signal configuration, meaning that the information of the originally configured first signal is active in cell A and the serving cell, while the information of the originally configured first signal cannot be introduced in cell B.

[0179] The information included in the first configuration information will be described in detail below. The first configuration information may include, for example, information common to multiple cells in the first region and / or unique information specific to the first cell.

[0180] Information common to multiple cells may be shareable among multiple cells; that is, multiple cells can all determine the information that constitutes the first signal based on the common information. In other words, information common to multiple cells can be applied to multiple cells. For example, the common information may include general-purpose parameters of the cross-cell. The common information may include, for example, configuration parameters related to several first signal configurations. For example, the common information may include time-frequency resource configuration, first signal sequence ID, periodicity, offset amount, comb type, resource type, etc. Making resource reservations for cells in the first region based on general-purpose parameters of the cross-cell may not affect the system. As one implementation, the common information may include some parameters in the parameter "SRS-Config".

[0181] The unique information specific to the first cell may be specific to the first cell. That is, when a terminal device camps on to the first cell, the information constituting the first signal may include the unique information of the first cell, or when a terminal device camps on to a cell other than the first cell, the information constituting the first signal may not include the unique information of the first cell. In one implementation, the unique information may include some of the parameters in the parameter "SRS-Config".

[0182] Unique information may relate to one or more pieces of information among the time of transmission of the first signal, the frequency of transmission of the first signal, and the positional relationship between the terminal equipment and the access network equipment. For example, unique information may include one or more pieces of information among the first pieces of information such as the number of periodic transmissions, resource type, bandwidth, and resource set list. The first piece of information of the resource set list may include one or more pieces of information among the number of SRS resources per set, periodicity, carrier frequency of the first signal, spatial relation information, and path loss reference information corresponding to the first resource set.

[0183] To distinguish between different cell-specific information, the specific information may include the cell identifier of the corresponding cell. For example, the specific information of a first cell may include the identifier of the first cell. In some embodiments, the specific information may include the cell identifier and one or more of the following: the number of periodic transmissions, resource type, bandwidth, and an SRS resource set list (e.g., including the number of SRS resources, period, and SRS carrier frequency for each set).

[0184] In some embodiments, the unique information may include a cell group identifier. The cell group identifier may include some or all of the cells in a plurality of cells within the first area. The identifier information of the first cell may be included in the cell group identifier in the unique information of the first cell. That is, the unique information may be specific to a single group of cells. When a terminal device camps on to any cell in the cell group, the information constituting the first signal may include the unique information, but when a terminal device camps on to a cell other than the cell group, the information constituting the first signal does not include the unique information.

[0185] If the information constituting the first signal is used to constitute the resources occupied by the first signal, then, with respect to the resources occupied by the first signal, cells within the first region that do not allocate the resources of the first signal to other terminal devices cannot use these resources to transmit other data or control channels; otherwise, significant interference would occur when the terminal device being positioned moves nearby. In this way, the resources of the first signal are used exclusively within a certain range, which increases resource consumption.

[0186] Regarding the above problem, this invention proposes that the first configuration information may be used to indicate multiple candidate configuration information. Any of the multiple candidate configuration information may be used to constitute the first signal. The terminal device can select one or more candidate configuration information from the multiple candidate configuration information to constitute the first signal. In the case where the first configuration information constitutes the resources for the first signal, the multiple candidate configuration information may be used to indicate multiple candidate resources, that is, a candidate resource pool can be indicated. The terminal device can select a resource to transmit the first signal from the candidate resource pool indicated by the first configuration information. The terminal device can also perform frequency hopping with the selected resource. Based on the above solution, resource multiplexing is achieved and interference is reduced.

[0187] In some embodiments, when a terminal device performs cell reselection in the first region, the access network device can transmit second instruction information to the core network device, which is used to instruct the cell to camp on after the terminal device has performed cell reselection. That is, after the terminal device has performed reselection, the second instruction information can notify the core network device of the new cell information after reselection.

[0188] After re-selection, the information constituting the first signal may change. Therefore, the second instruction information allows the core network equipment to know the configuration status of the first signal, thereby notifying neighboring cells and detecting the newly configured first signal.

[0189] One understandable point is that when a terminal device notifies the core network device of the new cell it is camping on, the terminal device needs to enter a connected state, which consumes power. Therefore, by having the access network device notify the positioning server, power consumption of the terminal device can be avoided.

[0190] In some embodiments, the cell to which the terminal device camps on before cell reselection is the third cell, the cell to which the terminal device camps on after cell reselection is the fourth cell, and the access network equipment is the access network equipment corresponding to the third or fourth cell. That is, the access network equipment corresponding to the original cell before cell reselection can transmit second instruction information, and / or the access network equipment corresponding to the new cell after cell reselection can transmit second instruction information. When the original cell transmits second instruction information, the core network equipment can know the new cell reselected by the terminal device early, determine the information that constitutes the first signal to be used by the terminal device based on the new cell, and notify the cell that needs to perform the first signal measurement to perform the measurement.

[0191] This invention does not limit how access network equipment determines second instruction information (i.e., a new cell after camp-on). For example, the second instruction information may be determined based on timing advance (TA) estimation results, sequence, and information of the first signal of time-frequency position.

[0192] In some embodiments, second instruction information can be determined based on the positioning status.

[0193] For example, a terminal device can transmit a first signal using a new configuration. Access network equipment can detect the newly configured first signal but cannot detect the original configured first signal. The access network equipment can report this information to the core network equipment, which can determine that the terminal device has performed cell reselection.

[0194] Furthermore, for example, a terminal device can transmit a first signal using a new configuration. In response to notification from the access network receiving the first signal, the core network device can determine the location of the terminal device itself, thereby determining the cell to which the terminal device will camp on.

[0195] In some embodiments, the access network device can perform blind detection for all signals. The blind detection process can detect the originally configured first signal and the newly configured first signal. Based on the blind detection status, the access network device can perform positioning measurements and report the measurement results obtained to the positioning server. The measurement results may include, for example, the first signal configuration and the measured values. The first signal configuration and measured values ​​may include, for example, the sequence and time-frequency position of the first signal. The positioning server associates the measurement results with the user ID and performs positioning calculations. According to the position of the terminal device, the cell to which the terminal device camps on can be determined. Blind detection is implemented in the following manner: the time-frequency sequence of the first signal before re-selection (e.g., the first cell) is s1, the time-frequency sequence of the first signal after re-selection (e.g., the second cell) is s2, both s1 and s2 are determined based on configuration information, and the actual sequence in which the access network device receives the first signal is r, and the formula

number

number

[0196] In some embodiments, second instruction information can be determined based on TA estimation. For example, a terminal device can transmit a first signal using its original configuration. An access network device corresponding to a new serving cell can use the received first signal to perform TA estimation. Based on the TA estimation result, the access network device can determine whether the terminal device is within its coverage area.

[0197] For low-power terminal devices, the TA value of the new cell after re-selection is obtained without performing a random access process. Therefore, neither the cell before nor after re-selection can determine the cell to which the terminal device will camp on. Thus, based on the above method, the access network device can determine the cell to which the terminal device will camp on, and thereby further inform the core network device of the status of the camp-on cell.

[0198] Core network devices can notify access network devices if the information constituting the first signal indicated by the first configuration information is already occupied. For example, an access network device can receive third instruction information transmitted from the core network device. The third instruction information may be information indicating the information used to constitute the first signal. In this way, the access network device does not have to use the configuration information and further avoids configuration information collisions. When the first signal is constituted by an access network device (e.g., a serving cell), other cells are unaware that the configuration (e.g., the configured resource) has already been used, and therefore the access network device (e.g., a serving cell) notifies the core network device of the configured configuration information. Furthermore, the core network device can notify cells that share the resource of the already configured configuration information, and when these cells constitute the first signal, they can avoid using the information constituting the first signal that has already been allocated as much as possible, thereby reducing collisions.

[0199] Furthermore, terminal devices and / or access network devices may transmit one or more of the following information to core network devices: information about the cell to which the terminal device is currently camp-on, the terminal device's identifier (ID), and information from the first area.

[0200] Furthermore, this application does not restrict the RRC state of the terminal device. For example, the method described herein can be executed by a terminal device in the RRC_INACTIVE state or the RRC_IDLE state.

[0201] Furthermore, with respect to UL positioning, in any case, the core network equipment (e.g., LMF) can request that the TRP of an adjacent cell receive the first signal transmitted from the terminal equipment.

[0202] The above describes in detail embodiments of the method of the present application, and the following describes in detail embodiments of the apparatus of the present application.
