Mode for Carrying Out the Invention

[0015] Hereinafter, the technical solution in the present application will be described with reference to the drawings. Communication system

[0016] FIG. 1 is a diagram showing a wireless communication system 100 applied to the embodiments of the present application. This wireless communication system 100 may include communication devices, and the communication devices may include network devices 110 and terminal devices 120. The network device 110 may be a device that communicates with the terminal device 120.

[0017] FIG. 1 exemplarily shows one network device and two terminal devices. Optionally, this wireless communication system 100 may include multiple network devices. Within the coverage range of each network device, other numbers of terminal devices may be included, and the embodiments of the present application do not limit this.

[0018] Optionally, this wireless communication system 100 may further include other network entities such as a network controller and a mobility management entity, and the embodiments of the present application do not limit this.

[0019] It should be understood that the technical solution of the embodiments of the present application can be applied to various communication systems, such as the 5th generation (5G) system or new radio (NR), long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD), etc. The technical solution according to the present application can also be applied to future communication systems such as the 6th generation mobile communication system and satellite communication system.

[0020] In the embodiments of this application, terminal equipment may also be called user equipment (UE), access terminal, user unit, user station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device. In the embodiments of this application, terminal equipment may also refer to devices that provide voice and / or data connectivity to a user, and can be used to connect humans, objects, and machines, such as handheld devices and in-vehicle devices with wireless connectivity. The terminal devices in the embodiments of this application may include mobile phones, tablet PCs (Pads), notebook computers, palmtop computers, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes. Optionally, the UE can function as a base station. For example, the UE can function as a scheduling entity and provide sidelink signals between UEs in vehicle-to-everything (V2X) or device-to-device (D2D) communication. For example, a cellular phone and a car communicate with each other using sidelink signals. It eliminates the need for base stations to relay communication signals, allowing communication between cellular phones and smart home devices.

[0021] In the embodiments of this application, the network equipment may be equipment for communicating with terminal equipment, and the network equipment may include access network equipment, which provides communication coverage to a specific geographic area and can communicate with terminal equipment 120 located within that coverage area. Access network equipment is also called radio access network equipment or base station equipment. In the embodiments of this application, access network equipment may refer to radio access network (RAN) nodes (or equipment) that provide access to terminal equipment on a radio network. The term "access network" broadly covers, or may be replaced by, various names such as NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, transmitting and receiving point (TRP), transmitting point (TP), master eNB (MeNB), secondary eNB (SeNB), multi-standard radio (MSR) node, home base station, network controller, access node, radio node, access point (AP), transmission node, transmit / receive node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), and positioning node. A base station may be a macro base station, a micro base station, a relay node, a donor node, or similar, or a combination thereof. A base station may further refer to a communication component, modem, or chip installed within the equipment or device mentioned in the preceding paragraph.A base station may also be a mobile switching center and equipment that performs base station functions in D2D, V2X, and machine-to-machine (M2M) communications, network-side equipment in a 6G network, or equipment that performs base station functions in future communication systems. A base station can support networks with the same or different access technologies. The embodiments of this application do not limit the specific technologies and specific forms of equipment used in access network equipment.

[0022] Base stations may be fixed or mobile. For example, a helicopter or drone may be configured as a mobile base station, and one or more cells may move depending on the location of this mobile base station. In another example, a helicopter or drone may be configured as equipment for communicating with another base station.

[0023] Communication equipment related to a wireless communication system may include not only access network equipment and terminal equipment, but also core network elements. Network elements can be implemented by equipment; that is, network elements are core network equipment. As can be understood, core network equipment may also be network equipment.

[0024] The core network elements in the embodiments of this application may include network elements that process and transmit user signaling and data. For example, the core network equipment may include core network equipment such as a core access and mobility management function (AMF), a session management function (SMF), a user plane gateway, and a location management function (LMF). The user plane gateway may be a server that has functions such as mobility management, routing, and transmission for user plane data, and is generally located on the network side, such as a serving gateway (SGW), a packet data network gateway (PGW), or a user plane function entity (UPF). Naturally, the core network may include other network elements, which will not be listed here.

[0025] In some deployments, the network equipment in the embodiments of the present invention refers to a CU or DU, or the network equipment may include both a CU and a DU. The gNB may further include an AAU.

[0026] Network equipment and terminal equipment may be configured on land, including indoors or outdoors, handheld or vehicle-mounted, on water, or in the air on airplanes, balloons, or satellites. The embodiments of this application do not limit the scenarios in which the network equipment and terminal equipment are located.

[0027] 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).

[0028] Discontinuous reception In some communication systems, network equipment can configure DRX functionality on terminal equipment. When DRX functionality is configured on terminal equipment, the terminal can intermittently monitor the physical downlink control channel (PDCCH), thereby achieving the goal of power saving for the terminal equipment.

[0029] Each medium access control (MAC) entity may have one DRX configuration. The DRX configuration parameters include one or more of the following: DRX cycle (drx cycle), DRX duration timer (drx-onDurationTimer), delay time for terminal equipment to activate the DRX duration timer (drx-StartOffset), DRX inactivity timer (drx-InactivityTimer), DRX retransmission timer (drx-RetransmissionTimer), and DRX uplink retransmission timer (drx-ULRetransmissionTimer).

[0030] When a terminal device configures a DRX, during the DRX's inactive period, the terminal does not monitor the PDCCH, i.e., it enters a sleep state, thereby saving power. When monitoring the PDCCH becomes necessary, the terminal device can wake up from sleep state, thereby entering the DRX active period. During the DRX active period, the terminal device is required to monitor the PDCCH.

[0031] The following explains the active period of DRX, using the DRX duration timer as an example. Figure 2 shows an example of the operation process of the DRX duration timer. As shown in Figure 2, within a DRX cycle, when the DRX duration timer is operating, i.e., within the duration shown in Figure 2, terminal equipment can monitor the PDCCH. In other words, the DRX active period includes this duration.

[0032] The DRX active period can be associated with other parameters or timers. For example, the DRX active period is associated with the DRX inactive timer. If the DRX inactive timer has not timed out, the current time will belong to the DRX active period, even if the DRX duration timer has timed out.

[0033] With advancements in communication technology, several communication protocols (e.g., 3GPP® Rel.13) introduce extended discontinuous reception (extended DRX, eDRX). When the user is idle, the DRX cycle and paging cycle are the same, but the parameters of eDRX differ. eDRX has a longer DRX cycle than DRX, allowing the terminal to conserve power better, but it can cause longer downlink data delays. Any subsequent references to DRX in this application include eDRX.

[0034] As is understood, DRX technology affects data transmission delay, but such delays rarely impact the user experience. Therefore, considering power saving in terminal equipment, implementing DRX is highly worthwhile.

[0035] For terminal devices in the RRC idle state, paging messages are generally received using a method similar to the DRX mechanism. There is one paging occasion (PO) within one DRX cycle. The terminal receives paging messages only during the PO period and does not receive paging messages at other times, thereby achieving power saving. The paging process is described below.

[0036] paging In some communication systems, network devices can send paging to terminal devices that are in an RRC idle state or an RRC connected state. The paging process may be triggered by the core network or a base station. The paging process may be used to send a paging request to a terminal device that is in an RRC idle state, or the paging process may be used to notify the terminal device of system information updates, or the paging process may be used to notify the terminal device that it has received warning information transmitted from an earthquake and tsunami warning system (ETWS) and a commercial mobile alert system (CMAS).

[0037] Paging messages are carried over the physical downlink shared channel (PDSCH). Before receiving a paging message, terminal equipment must first receive paging parameters via a system message and combine them with the terminal equipment identifier (UE_ID) to calculate the frame number of the paging frame (PF) where the paging message is located, as well as the PO (Paging Instruction). Subsequently, within the PO on the PF, the terminal equipment monitors the PDCCH, which has been scrambled by the paging radio network temporary identity (P-RNTI), to receive paging instruction information, and finally receives the paging message based on the paging instruction information. If the user configures a paging time window (PTW), the terminal equipment can only monitor the paging channel based on the DRX cycle within the paging time window, thereby receiving downlink services. Outside of the PTW, the terminal equipment is in a sleep state, meaning it does not monitor the paging channel and cannot receive downlink services.

[0038] The above PF indicates the frame number of the system frame in which the paging message should appear, and PO indicates the time at which the paging message may appear. Figure 3 shows the location of PFs within a DRX cycle and the location of POs within PFs. As shown in Figure 3, PFs are located within a DRX cycle (or paging cycle), and a single PF may contain one or more POs, and these multiple POs may correspond to different terminal devices. However, for a given terminal device, within a DRX cycle (or paging cycle), it only needs to monitor the POs that belong to it.

[0039] Terminal devices can calculate PFs and POs based on their UE_ID. In some embodiments, a system frame corresponding to a system frame number (SFN) satisfying the formula (SFN + PF_offset) mod T = (T div N) * (UE_ID mod N) can be one PF, and within the PF, the index i_s of the PO corresponding to the terminal device can be calculated based on the formula i_s = floor(UE_ID / N) mod Ns. T represents the cycle length of the terminal device's DRX cycle, UE_ID represents the identifier of the terminal device, N represents the number of PFs in the DRX cycle, and Ns represents the number of POs in one PF. PF_offset represents the frame offset of the PF.

[0040] Positioning technology As communication technology matures, some communication systems (e.g., 5G systems) can implement an increasing number of communication algorithms. These communication algorithms may include high-speed information transmission and positioning technologies. For example, indoor and outdoor positioning navigation systems, primarily based on satellite navigation technology such as Beidou and supplemented by ultra-wideband (UWB) and 5G technologies, are profoundly influencing the lifestyles of modern people.

[0041] Wireless communication systems may include servers. Servers generally have high computing power, large memory capacity, and high throughput efficiency. As can be seen from this, servers can simultaneously perform tasks such as computing large amounts of data and can implement algorithms of relatively high complexity. Therefore, in related technologies, it is possible for servers to settle the location coordinates of terminal devices. Such servers may also be called positioning servers.

[0042] The positioning server may be a network device with positioning functionality provided by a service provider. The network device with positioning functionality may be a core network device or a cloud server. For example, the positioning server according to the embodiment of the present application may include one or more of LMF, location management component (LMC), and local location management function (LLMF) located in the network device, and the embodiment of the present application is not limited thereto.

[0043] Positioning technologies can be divided into uplink positioning, downlink positioning, and uplink-downlink coordinated positioning. In any of these positioning technologies, positioning can be achieved using a first signal. The first signal may include, for example, a reference signal. The reference signal may be, for example, a sounding reference signal (SRS) or a positioning reference signal (PRS). When performing uplink positioning, the access network equipment corresponding to the serving cell can transmit SRS configuration information. Terminal equipment can transmit SRS based on the SRS configuration information. Access network equipment corresponding to the serving cell and adjacent cells can receive SRS. Based on the received SRS, the access network equipment can estimate information such as power, time delay, or angle, and calculate this information to obtain the user's location information or report this information to the positioning server. The positioning server can calculate the location of the terminal equipment based on the reported information and thereby obtain the terminal equipment's location information.

[0044] When performing downlink positioning, both the access network device corresponding to the serving cell and the access network device corresponding to the adjacent cell can transmit PRS. Terminal devices can measure the received PRS and report the measured information to the network devices. The positioning server can calculate the location of the terminal device based on the reported information, thereby obtaining the terminal device's location information.

[0045] As mentioned above, the positioning process requires the terminal device to transmit and / or measure a first signal for positioning. Therefore, the terminal device needs to wake up from sleep mode. The wake-up process requires the terminal device to perform operations such as measurement and synchronization, which causes significant power consumption in the terminal device.

[0046] To address the above problem, the embodiment of the present application provides a wireless communication method shown in Figure 4. The method shown in Figure 4 is performed by a first communication device. The method shown in Figure 4 may include step S410.

[0047] In step S410, the first communication device determines the second information based on the first information, and / or the first communication device determines the first information based on the second information.

[0048] The first information may relate to a time window for transmitting and / or measuring a first signal. The first signal may be a signal for positioning of a terminal device. For example, the first signal may include PRS and / or SRS. The first signal may correspond to a serving cell or an adjacent cell. When measuring the first signal, the time window may be called a measurement gap. Taking the first signal as an example, if the first signal includes a PRS, within the measurement gap, the terminal device can measure the PRS transmitted from the access network device corresponding to the serving cell or adjacent cell. When transmitting the first signal, the time window may be called a processing window. Taking the first signal as an example, if the first signal includes an SRS, within the processing window, the terminal device can transmit an SRS to the access network device corresponding to the serving cell or adjacent cell.

[0049] Note that a time window may refer to a fixed time region. Therefore, a time window may also be called a time period or time region. When indicated by time units, a time window may include at least one time unit. A time unit may include, for example, a subframe, an orthogonal frequency division multiplexing (OFDM) symbol, etc.

[0050] Furthermore, this application does not limit the method of indicating the time window. For example, the time window may be indicated by one or more parameters such as the time window start time, the time window end time, and the time window length.

[0051] The second information may relate to DRX parameters and / or paging parameters. DRX parameters may include parameters that describe the DRX cycle. For example, DRX parameters may include one or more of the following: the start time of the DRX cycle, the duration of the DRX cycle, the DRX activation time (i.e., the start time of the DRX active period), the duration of the DRX active period, the start time of the DRX duration, the duration of the DRX duration, and parameters of timers associated with the DRX. Paging parameters may include a time domain corresponding to paging detection. The time domain corresponding to paging detection may be indicated by PF and / or PO.

[0052] As mentioned above, the DRX process and paging process also relate to the wake-up process. The present invention can consider a combination of the first and second information to select one or more of the appropriate time window, DRX parameters, and paging parameters for measuring and / or transmitting the first signal, thereby reducing the total number of wake-ups as much as possible and lowering the power consumption of the terminal equipment. For example, after one wake-up, the terminal equipment can not only measure and / or transmit the first signal, but also perform operations that need to be performed during the paging and / or DRX active period. Such embodiments reduce the number of wake-up processes by at least one compared to measuring and / or transmitting the first signal to perform one wake-up, and paging and / or DRX active performing another wake-up, thereby lowering the power consumption of the terminal equipment. Alternatively, after waking up from deep sleep, the DRX process and paging process are performed, and after measuring or transmitting the first signal, some or all functions do not enter a low-power state. Therefore, even if it is necessary to wake up the terminal device again, the power consumption when waking it up again can be reduced compared to waking it up from deep sleep mode.

[0053] Furthermore, the resources of the first signal can be rationally configured based on this application. Taking the first signal as a PRS as an example, configuring a small PRS period ensures that the terminal device always has PRS resources available when it wakes up. Such a processing method is equivalent to the PRS waiting for the terminal device to measure. Sufficient PRS resources are required to keep the PRS in a waiting state at all times. If the accuracy requirements for positioning by the terminal device are relatively high, the PRS bandwidth is relatively wide, and the PRS resources are always waiting for measurement, consuming a large amount of resources and thus causing resource waste. Therefore, this application makes it possible to determine an appropriate time window for transmitting and / or measuring the first signal based on the DRX parameters and / or paging parameters, thereby configuring rational resources for the first signal and further avoiding resource waste.

[0054] When a first communication device determines second information based on first information, the time window for transmitting and / or measuring the first signal can be kept constant, and the DRX parameters and / or paging parameters can be adapted to this time window. On the one hand, the paging cycle is related to the identifier of the terminal device, and the space for adjustment is relatively small. On the other hand, considering that the DRX cycle is configured based on the power consumption and paging time requirements, it is difficult to adjust it significantly. Therefore, in some embodiments, the DRX parameters and / or paging parameters can be kept constant, and the time window for transmitting and / or measuring the first signal can be adapted to it, thereby simplifying the implementation of the configuration process.

[0055] In some embodiments, the first communication device may include a positioning server. Once the first information is determined, the first information determined by the positioning server can be associated not only with the serving cell of the terminal device but also with adjacent cells. That is, the positioning server can realize the coordinated design of the first signal between multiple cells, thereby avoiding interference caused by the non-orthogonal nature of the first signals between multiple cells. Also, since the terminal device moves between cells, when configuring the first signal resources for the terminal device, the terminal device can be configured with first signal resources for multiple cells, and this configuration can operate for a certain period of time and will not change immediately. That is, if the terminal device re-selects a cell or changes its serving cell, the configuration of the first signal may not change. For this reason, the first signal resources for each cell are generally designed for terminal devices with multiple cells. Consider the bandwidth occupied by the first signal and the number of multi-cell terminal devices that support positioning simultaneously. By having the positioning server determine the first information, the configuration and transmission of the first signal can be made more directional and efficient.

[0056] In some embodiments, the first communication device may include one or more of the above-mentioned terminal devices, access network devices, etc. For example, the terminal device itself can perform the method shown in Figure 4.

[0057] The method shown in Figure 4 may also be performed by a second communication device. The second communication device may include terminal equipment and / or network equipment. The method shown in Figure 4 may further include step S405.

[0058] Step S405, the second communication device transmits instruction information to the first communication device. The instruction information may include the first instruction information and / or the second instruction information.

[0059] If the second information is determined based on the first information, the first instruction information may be used to indicate the first information, and if the first information is determined based on the second information, the first instruction information may be used to indicate the second information. That is, other communication devices determine the first information and instruct the first communication device to determine the first information, so that the first communication device determines the second information based on the first information. Other communication devices determine the second information and notify the first communication device of the second information, so that the first communication device determines the first information based on the second information.

[0060] In some cases, the first communication device cannot acquire the first information and therefore cannot determine the second information. In some cases, the first communication device cannot acquire the second information and therefore cannot determine the first information. For example, if the first communication device is an LMF, the LMF cannot acquire the terminal device's DRX parameters and therefore cannot determine the time window for transmitting and / or measuring the first signal based on the DRX parameters. In this case, the terminal device and / or access network device can act as a second communication device and transmit first instruction information to the LMF indicating the DRX parameters, thereby allowing the LMF to acquire the DRX parameters. Continuing with the example that the first communication device includes an LMF, as described above, during downlink positioning, the terminal device needs to detect not only the first signal of the serving cell but also the first signal of adjacent cells. Some parameters used by the terminal device for paging are cell-specific, such as the terminal device's paging frame offset for paging. Also, due to the mobility of the terminal device, cell reselection may occur; that is, the paging occasion in the time domain changes when a cell is reselected. However, the LMF does not know the information related to the paging configuration of the terminal equipment. In this case, the terminal equipment and / or access network equipment act as second communication devices and send first instruction information specifying the paging parameters to the LMF.

[0061] Furthermore, the first communication device does not need to acquire the first or second information based on the first instruction information. For example, in some cases, the first communication device can determine the first information itself, and thereby determine the second information based on the first information. Similarly, in some cases, the first communication device can determine the second information itself, and thereby determine the first information based on the second information. Taking the example that the first communication device includes terminal equipment, the terminal equipment can determine the DRX parameters and / or paging parameters itself, and thereby determine the first information. Therefore, the first communication device does not need to receive the first instruction information.

[0062] The second instruction information may be used to indicate the RRC state of the terminal device. Based on the RRC state and the identifier of the terminal device, the first communication device can determine the second information, and thereby determine the first information based on the second information. For example, if the RRC state is idle or inactive, the first communication device can determine the second information based on the identifier of the terminal device after obtaining the RRC state of the terminal device.

[0063] In some embodiments, the first communication device can determine a time domain corresponding to paging detection based on the identifier of a terminal device, and further determine first information based on that time domain. In that time domain, the terminal device can perform paging detection. The time domain corresponding to paging detection may be indicated by parameters such as PF and PO. That is, the first communication device can determine PF and / or PO based on the identifier of the terminal device, thereby determining first information related to the time window for transmitting and / or measuring the first signal.

[0064] In some embodiments, the second communication device can actively transmit instruction information to the first communication device. For example, the second communication device can periodically transmit instruction information to the first communication device.

[0065] In some embodiments, if the first communication device requires instruction information, the first communication device may send a request to obtain the corresponding instruction information. For example, the first communication device may send a first request and / or a second request. The first request may be used to request the acquisition of first instruction information. The second request may be used to acquire second instruction information. Upon receiving the first request, the second communication device may transmit the first instruction information to the first communication device, and upon receiving the second request, the second communication device may transmit the second instruction information to the first communication device.

[0066] The instruction information may be carried in one or more of the following: location positioning protocol (LPP) signaling, new radio positioning protocol a (NRPPa) signaling.

[0067] Taking LPP signaling as an example, instruction information may be carried in messages relating to the LPP capability transmission procedure. Figure 5 is a schematic flowchart of the interaction of DRX parameters and / or paging parameters in an LPP-based positioning procedure according to an embodiment of the present invention. The method shown in Figure 5 may be performed by an LMF, an AMF, access network equipment and terminal equipment. The first communication equipment is an LMF, and the second communication equipment may include access network equipment and / or terminal equipment.

[0068] The method shown in Figure 5 may include steps S510 to S580.

[0069] Step S510 and / or step S520 are used to implement LPP capability transfer.

[0070] The LMF request DRX parameters and / or paging-related parameters, as well as the response performed by the terminal device or access network device, may be performed by steps S510 and / or S520. The LMF may send a first request to the terminal device or access network device to request that the terminal device or access network device send parameters or parameter sets relating to DRX, eDRX, and paging. The terminal device or access network device may respond to the first request by sending the parameters of the LMF request.

[0071] Step S530: LPP assists in data delivery.

[0072] Step S540 and / or Step S550: LPP requests location information.

[0073] Step S560: The terminal device performs location measurements.

[0074] Step S570: The terminal device triggers a service request or connection resume (UE triggered service request or connection resume).

[0075] Step S580: LPP provides location information.

[0076] The time between steps S540 and S580 is the LPP response time.

[0077] Taking NRPPa signaling as an example, an access network device can notify an LMF terminal device of its DRX parameters and / or paging parameters via NRPPa signaling. This NRPPa signaling may be transmitted from the access network device to the LMF when the terminal device accesses a serving cell. Alternatively, the first communication device may include an AMF and / or LMF, and when the first communication device sends a first request to the terminal device, it requests parameters or a set of parameters relating to the terminal device's DRX, eDRX, and paging. The access network device can respond to the first request and initiate the requested parameters. Alternatively, for terminal devices that support location measurement, in the positioning procedure, the access network device may notify the first communication device of the user's DRX and / or paging information, and the first communication device may include an AMF.

[0078] In some embodiments, the access network device or the first communication device may receive instruction information transmitted from the second communication device in response to receiving a positioning request from a terminal device, or in response to the completion of the selection of a positioning server, the first communication device may receive instruction information transmitted from the second communication device. For example, if the first communication device includes an LMF, the AMF may transmit instruction information to the LMF after it has completed its selection for the LMF. Alternatively, the access network device may transmit instruction information to the LMF upon receiving a positioning request.

[0079] The following describes the instruction process for instruction information, referring to the positioning procedure shown in Figure 6. The positioning method shown in Figure 6 may also consist of terminal equipment, access network equipment (e.g., NR-RAN), AMF, LMF, visited gateway mobile location center (V-GMLC), home gateway mobile location center (H-GMLC), unified data management (UDM), location services client (LCS client), NEF, and application function (AF).

[0119] Step S631: The terminal device performs event detection.

[0120] As can be seen from Figure 6, in the positioning procedure shown in Figure 6, in step S613, the AMF can perform LMF selection. Once the LMF selection is complete, the AMF can transmit instruction information to the LMF, which is the first communication device, as the second communication device. Alternatively, when the access network device receives a positioning request, it can notify the LMF, which is the first communication device, of instruction information as the second communication device. Alternatively, when the LMF, which is the first communication device, receives a positioning request, it can receive instruction information transmitted from the access network device, which is the second communication device.

[0121] Once the first communication device has determined the first information, it can transmit the first information to the second communication device. The second communication device can refer to the first information and configure a time window for transmitting and / or measuring the first signal. The first communication device may include, for example, a positioning server. The second communication device may include, for example, one or more terminal devices, access network devices corresponding to the serving cell of the terminal device, and access network devices corresponding to the adjacent cells of the terminal device.

[0122] In some embodiments, the first signal may be carried in a constituent message or an auxiliary message of the first signal. The following explanation will illustrate this with reference to Figure 7, using the example that the first signal includes an SRS. While Figure 7 uses an SRS as an example, the method shown in Figure 7 can be applied to other first signals, such as a PRS.

[0123] Figure 7 shows some steps of the uplink positioning process. The steps shown in Figure 7 may be performed by the access network equipment corresponding to the serving cell, the access network equipment corresponding to the adjacent cell, and the LMF. When performing uplink positioning based on Figure 7, the LMF can send information requests to the access network equipment corresponding to the serving cell and the adjacent cell, respectively, before performing the positioning measurement. The access network equipment corresponding to the serving cell and the access network equipment corresponding to the adjacent cell can notify the LMF of candidate SRS configuration information. This will be explained in detail below.

[0124] In step S710, the LMF sends a TRP information request to the access network device corresponding to the serving cell and the access network device corresponding to the adjacent cell.

[0125] In step S710, when the LMF sends the TRP information request, it may also send the desired time for the SRS resource and other parameters. These other parameters may include, for example, the operating frequency bandwidth.

[0126] Prior to step S710, the LMF requests the access network device or terminal device to provide a section in which an SRS can be configured, or the access network device or terminal device reports a section in which an SRS can be configured. The terminal device identifier may be reported at the same time as the access network device or terminal device reports.

[0127] In step S720, the access network equipment corresponding to the serving cell and the access network equipment corresponding to the adjacent cell each provide a TRP information response to the LMF. The TRP information response may include a candidate SRS config.

[0128] This shows that the TRP information exchange process is implemented based on steps S710 and S720. The LMF collects candidate SRS configurations for the TRP through the TRP information exchange process. Note that steps S710 and S720 may be performed before the positioning process.

[0129] In steps S730a and S740a, the LMF sends an NRPPa message "assistance information control" to the access network device corresponding to the serving cell, receives "assistance information feedback," and enables the access network device to transmit the configured SRS.

[0130] As described above, the second communication device that receives the first information can refer to the first information to realize the configuration of a time window for transmitting and / or measuring the first signal. Furthermore, the first information may also include information about the actually configured time window for transmitting and / or measuring the first signal, and by transmitting the first information, the first communication device can notify other communication devices of the actual configuration of the time window for transmitting and / or measuring the first signal, thereby achieving accurate positioning. This will be explained in detail below with reference to Figure 8.

[0131] The method shown in Figure 8 relates to a pre-configured measurement gap and a pre-configured processing window (PPW).

[0132] The method shown in Figure 8 includes steps S810 to S870.

[0133] In step S810, TRP information exchange takes place between the access network device and the positioning server.

[0134] In step S820, the positioning server sends a measurement preconfiguration request (NRPPa MEASUREMENT PRECONFIGURATION REQUIRED) to the access network device.

[0135] In step S830, the access network device sends an RRC reconfiguration message to the terminal device. This RRC reconfiguration message includes pre-configured PRS processing window configurations.

[0136] In step S840, the terminal device sends an RRC reconfiguration complete message to the access network device.

[0137] Some communication standards (e.g., R17) introduce pre-configured measurement gaps and PPWs to reduce positioning delays. As can be seen in Figure 8, for this function, steps S810 and S840 introduce the NRPPa message "Required measurement pre-configuration / confirmation," which is used to transmit the PRS configuration of the adjacent cell of the terminal device to the access network device corresponding to the serving cell, thereby allowing the access network device of the serving cell to pre-configure the PPW or measurement gap for the terminal device.

[0138] In step S850, the access network device sends a measurement preconfiguration confirmation (NRPPa MEASUREMENT PRECONFIGURATION CONFIRM) to the positioning server.

[0139] In step S860, the positioning server sends a measurement activation (NRPPa MEASUREMENT ACTIVATION) command to the access network device.

[0140] In step S870, the access network device sends a PPW activation or deactivation command (DL MAC CE PPW Activation / Deactivation Command) via the downlink MACCE.

[0141] In step S880, the positioning server sends a first signal transmission request to the access network device corresponding to the adjacent cell.

[0142] If the first signal includes a PRS, the first signal transmission request may be called a PRS transmission request (NRPPa PRS transmission required).

[0143] In step S890, the positioning server receives a first signal transmission acknowledgment transmitted from the access network device corresponding to the adjacent cell.

[0144] If the first signal includes a PRS, the first signal transmission confirmation may be called a PRS transmission confirmation (NRPPa PRS transmission confirm).

[0145] As can be seen from the above, steps S840 and S850 can indicate possible PPW and measurement gap, and steps S880 and S890 can notify the PPW and measurement gap of the first signal actually transmitted to the adjacent cell.

[0146] The method shown in Figure 8 may optionally further include steps S882 and S892.

[0147] In step S882, the positioning server sends a first signal transmission request to the access network device corresponding to the serving cell.

[0148] In step S892, the positioning server receives a first signal transmission acknowledgment sent from the access network device corresponding to the serving cell.

[0149] In some embodiments, the first information includes one or more of the following: a candidate time window for transmitting the first signal; a candidate time window for measuring the first signal; the start time of the time window; and the duration of the time window.

[0150] The candidate time window may be a time window available for transmitting and / or measuring the first signal. Within the candidate time window, a time window can be selected for transmitting and / or measuring the actually configured first signal. As can be seen from this, the first information determined by the first communication device is not necessarily the time window for transmitting and / or measuring the actually configured first signal. In other words, the first information may provide a suggestion for the configuration of a time window so as to constitute a time window. For example, if the first communication device includes an LMF, the LMF can determine a candidate time window and transmit it to the access network device, which then negotiates the actually configured time window. After interacting with the access network device, the LMF can select the actually configured time window from the candidate time window.

[0151] If the first information includes the start time and / or duration of a time window, the first information determined by the first communication device may also be the time window in which the configured first signal is transmitted and / or measured. In other words, the first communication device can determine the time window in which the first signal is transmitted and / or measured. For example, if the first communication device is a terminal device, the terminal device can determine the time window in which the first signal is transmitted and / or measured, and thereby transmit and / or measure the first signal within that time window.

[0152] As described above, the time window for transmitting and / or measuring the first signal may be determined based on the time domain corresponding to paging detection. For example, the time window can be configured with an offset value before or after the time domain corresponding to paging detection. Such a setting allows the transmission and / or measurement of the first signal and paging detection to be achieved in a single wake-up, thereby reducing the number of wake-ups and further reducing the power consumption of the terminal equipment. The offset value should not advance or delay the time window too much.

[0153] In some embodiments, the time window for transmitting and / or measuring the first signal may be determined based on the DRX active period. For example, the time window may be configured in the vicinity of the DRX active period. For example, the start time of the time window may be configured before the DRX active period. Alternatively, the start time of the time window may be configured after the DRX active period. Alternatively, there may be no gap between the time window and the DRX active period.

[0154] As described above, the time window for measuring the first signal may be understood as a measurement gap. Data transmission cannot be performed within the measurement gap. Therefore, this application proposes that the time window for measuring the first signal does not overlap with the DRX active period. Furthermore, regarding the time window for transmitting the first signal, the first signal belongs to uplink transmission, and the DRX active period is used for transmitting downlink signals. If the time window for transmitting the first signal does not overlap with the DRX active period, simultaneous uplink and downlink scheduling can be avoided, and the complexity of scheduling can be reduced. In summary, this application provides that the time window for measuring and / or transmitting the first signal does not overlap with the DRX active period.

[0155] The start time of the time window for transmitting and / or measuring the first signal may be determined based on a first offset amount. The first offset amount may be related to one or more of the DRX active period, PPW parameters, and paging cycles.

[0156] In one embodiment, the first offset amount may be determined based on whether the time window for transmitting and / or measuring the first signal is within the PPW. For example, if the time window is within the PPW, the first offset amount can take a first value, and if the time window is outside the PPW, the first offset amount can take a second value. The first and second values ​​may be different. If the time window is within the PPW, the DRX may be a general DRX, i.e., the first offset amount may be determined based on the DRX cycle. If the time window is outside the PPW, the DRX may be an eDRX, i.e., the first offset amount may be determined based on the eDRX cycle.

[0157] In one embodiment, the start time of the time window may be determined based on paging parameters. For example, the system frame number corresponding to the start time can satisfy (SFN + PF_offset + Pos_offset) mod T = (T div N) * (UE_ID mod N), where SFN is the system frame number, Pos_offset is the first offset amount, T is the cycle length of the DRX cycle of the terminal device, UE_ID is the identifier of the terminal device, N is the number of paging frames PF in the DRX cycle, and Ns is the number of paging occasions PO in one PF. PF_offset is the frame offset of the PF, and mod is the modulo operation. If the time window is located within a single system frame, the system frame number corresponding to the start time may be called the system frame number corresponding to the time window.

[0158] In one embodiment, the start time of the time window may be obtained by offsetting the first offset amount forward, based on the DRX activation time. The DRX activation time may be, for example, the start time of the DRX duration.

[0159] As mentioned above, the length of the DRX active period is not constant and may overlap with the duration, and may also be extended by the DRX inactivity timer. If the start time of the time window for transmitting and / or measuring the first signal is some time after the DRX activation time, it may cause data interruption or a relatively long active period. For example, there may be cases where the time length between the DRX activation time and the start time of the time window is short, and it is necessary to transmit and / or measure the first signal before the DRX active period has ended, i.e., entering a measurement gap within the DRX active period, thereby interrupting data transmission. If the time length between the DRX activation time and the start time of the time window is long, the time length between the end of the DRX active period and the start time maintains synchronization with the network side, thereby consuming unnecessary power. Therefore, the start time of the time window for transmitting and / or measuring the first signal according to this application is a time corresponding to a first offset amount before the DRX activation time. Such a setting method can not only avoid data transmission interruption but also reduce power consumption.

[0160] The first offset amount may be pre-set. For example, the first offset amount may be defined in a standard. Alternatively, the first offset may be determined by the first communication device.

[0161] In one possible embodiment, the first offset may be related to a time window in which the first signal is transmitted and / or measured. For example, the first offset amount may be greater than or equal to the time length of the time window. However, the first offset amount should not be greater than the time length of the time window in order to avoid unnecessarily long periods of time maintaining synchronization between the terminal device and the network device after a single wake-up, which would result in high power consumption. For example, the first offset amount may be less than or equal to a first time threshold. The first time length threshold is slightly greater than the time length of the time window.

[0162] In some embodiments, the length of the time window for transmitting and / or measuring the first signal may be related to the capabilities of the terminal device. The terminal device may transmit the length of the time window, determined based on its capabilities, to the first communication device, thereby configuring the resources for the first signal.
