Description

Configuration information switching method, terminal device, and network device Technical Field

[0001] The embodiments of the present application relate to the field of communications, and more specifically, to a configuration information switching method, a terminal device, and a network device. Background Art

[0002] When a terminal device moves within multiple cells in a Radio Resource Control (RRC) deactivated state, if the terminal device sends a positioning sounding reference signal (SRS) according to the configuration of the previous cell, due to improper use of the power parameters of the positioning SRS or improper uplink transmission beam, it may cause interference to other cells in the effective positioning area or make the network equipment unable to normally estimate the positioning SRS sent by the terminal device, thereby affecting the positioning accuracy.

[0003] Therefore, when the terminal device moves in the RRC inactive state within the effective positioning area of ​​the terminal device and moves to the coverage of different cells and / or different beams, the terminal device needs to adjust the transmission power and transmission beam direction of the positioning SRS. Generally, if the network device wants to reconfigure the positioning SRS of the terminal device, the terminal device needs to switch from the RRC deactivated state to the RRC connected state, which will increase the energy consumption of the terminal device, and for battery-powered terminal devices, especially Internet of Things (IoT) devices, it will reduce the battery life of the terminal device.

[0045] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0046] FIG1 is an example diagram of a 5G communication system 100 according to an embodiment of the present application.

[0047] As shown in Figure 1, a communication system 100 may include a terminal device 110, a first transmission reception point (TRP) 121, and a second TRP 122. The first TRP 121 and the second TRP 122 may each communicate with the terminal device 110 via an air interface. Specifically, the first TRP 121 and the second TRP 122 may independently schedule a terminal device 110 for data transmission.

[0048] For example, the terminal device 110 detects the PDCCH from the first TRP 121 and the second TRP 122 respectively in a time slot to schedule multiple independent uplink data transmissions, and these independent uplink transmissions may be scheduled in the same time slot.

[0049] However, in the communication system shown in FIG1 , there may be multiple communication scenarios.

[0050] For example, the first TRP 121 and the second TRP 122 belong to the same cell, and the connection (backhaul) between the first TRP 121 and the second TRP 122 is ideal, that is, information interaction can be performed quickly and dynamically.

[0051] For another example, the first TRP 121 and the second TRP 122 belong to the same cell, and the connection between the first TRP 121 and the second TRP 122 is non-ideal, that is, the first TRP 121 and the second TRP 122 cannot exchange information quickly, and can only perform relatively slow data interaction.

[0052] For another example, the first TRP 121 and the second TRP 122 belong to different cells, and the connection between the first TRP 121 and the second TRP 122 is ideal.

[0053] For another example, the first TRP 121 and the second TRP 122 belong to different cells, and the connection between the first TRP 121 and the second TRP 122 is non-ideal.

[0054] Because the network equipment can send different NR-PDCCH / NR-PDSCH from multiple TRPs to the terminal equipment, that is, the terminal equipment receives downlink information through multiple downlinks, where each downlink has corresponding uplink information to be transmitted, and the uplink information includes at least one of the following signals: confirmation / non-confirmation (ACK / NACK) corresponding to each downlink, reporting information such as channel state information (CSI) corresponding to each downlink, and uplink data.

[0055] It can be seen that if the terminal device 110 also needs to send uplink information on uplinks corresponding to multiple downlinks, the complexity and power consumption of the terminal device will be too high.

[0056] In response to the above-mentioned problems, an embodiment of the present application provides an uplink signal transmission method, which can effectively reduce the complexity and excessive power consumption of the terminal device by instructing the terminal device on the transmission mode of the uplink signal through the network device.

[0057] It should be understood that the embodiments of the present application are only illustrative using the 5G communication system 100 as an example, but the embodiments of the present application are not limited thereto. That is to say, the technical solutions of the embodiments of the present application can be applied to any communication system in which multiple network devices can independently schedule a terminal for data transmission. For example, by mapping the TRP in Figure 1 to a beam, an application scenario example as shown in Figure 2 can be obtained, which includes a terminal device 130 and a network device 140, wherein there are multiple beams between the terminal device 130 and the network device 140.

[0058] For example: Global System of Mobile communication (GSM) system, Code Division Multiple Access (CDMA) system, Wideband Code Division Multiple Access (WCDMA) system, General Packet Radio Service (GPRS), Long Term Evolution (LTE) system, LTE Time Division Duplex (TDD), Universal Mobile Telecommunication System (UMTS), etc.

[0059] This application describes various embodiments in conjunction with network devices and terminal devices.

[0060] The network device 130 may refer to any entity on the network side that is used to send or receive signals. For example, it may be a user equipment for machine type communication (MTC), a base transceiver station (BTS) in GSM or CDMA, a base station (NodeB) in WCDMA, an evolved Node B (eNB or eNodeB) in LTE, or a base station device in a 5G network.

[0061] In addition, the terminal device 110 can be any terminal device. Specifically, the terminal device 110 can communicate with one or more core networks via a radio access network (RAN), and can also be referred to as an access terminal, user equipment (UE), user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device. For example, it can be a cellular phone, a cordless phone, a Session Initiation Protocol (SIP) phone, a wireless local loop (WLL) station, a personal digital assistant (PDA), a handheld device with wireless communication capabilities, a computing device or other processing device connected to a wireless modem, an in-vehicle device, a wearable device, and a terminal device in a 5G network.

[0062] It should be noted that the term "indication" involved in the embodiments of the present application can be a direct indication, an indirect indication, or an indication of an associated relationship. For example, A indicates B, which can mean that A directly indicates B, for example, B can be obtained through A; it can also mean that A indirectly indicates B, for example, A indicates C, and B can be obtained through C; it can also mean that there is an associated relationship between A and B. The term "correspondence" can mean that there is a direct or indirect correspondence between the two, or it can mean that there is an associated relationship between the two, or it can mean a relationship between indication and being indicated, configuration and being configured, etc. In addition, the description "at the time of..." involved in the embodiments of the present application can be interpreted as "if" or "if" or "when..." or "in response to". Similarly, depending on the context, the phrase "if it is determined" or "if (the stated condition or event) is detected" can be interpreted as "when it is determined" or "in response to the determination" or "when (the stated condition or event) is detected" or "in response to detecting (the stated condition or event)". The term "predefined" or "predefined rules" can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in a device (for example, including a terminal device and a network device), and this application does not limit its specific implementation method. For example, predefined can refer to what is defined in the protocol. It should also be understood that in the embodiment of the present application, the "protocol" may refer to a standard protocol in the field of communications, for example, it may include LTE protocol, NR protocol and related protocols used in future communication systems, and this application does not limit this. In addition, in the embodiment of the present application, the term "and / or" is merely a description of the association relationship of associated objects, indicating that three relationships may exist. Specifically, A and / or B can represent three situations: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the previous and subsequent associated objects are in an "or" relationship.

[0063] To facilitate understanding of the solutions provided by this application, the relevant technologies and terms are explained below.

[0064] (1) Radio Resource Control (RRC) status of the terminal device.

[0065] The Radio Resource Control (RRC) status of a terminal device may include:

[0066] RRC deactivated (RRC_INACTIVE) state, RRC idle (RRC_IDLE) and RRC connected (RRC_CONNECTED) state.

[0067] Among them, for the RRC_CONNECTED state, there is an RRC connection between the network device and the terminal device, and there is a UE AS context between the network device and the terminal device, that is, the network device knows the location of the terminal device at a specific cell level, the mobility of the terminal device is controlled by the network device, and unicast data can be transmitted between the network device and the terminal device. For the RRC_IDLE state, there is no UE access stratum (AS) context on the network device side, nor is there an RRC connection. The mobility of the terminal device is implemented based on cell selection and reselection. The paging of the terminal device is initiated by the core network (CN), and its paging area is configured by the CN. For the RRC_INACTIVE state, there is a connection between CN and NR, the UE AS context exists on a certain base station, the mobility of the terminal device is implemented based on cell selection and reselection, the paging of the terminal device is triggered by the radio access network (RAN), and its paging area is managed by the RAN. The network device knows that the location of the terminal device is based on the paging area level of the RAN.

[0068] In addition, the terminal device can switch or transition between various RRC states. For example, a UE in the RRC_CONNECTED state can enter the RRC_IDLE state by releasing the RRC connection; a UE in the RRC_IDLE state can enter the RRC_CONNECTED state by establishing an RRC connection; a UE in the RRC_CONNECTED state can enter the RRC_INACTIVE state by suspending (Release with Suspend) the RRC connection; a UE in the RRC_INACTIVE state can enter the RRC_CONNECTED state by resuming (Resume) the RRC connection, and of course, it can also enter the RRC_IDLE state by releasing the RRC connection.

[0069] The network device can control the UE to perform state transition.

[0070] (2) Positioning SRS in NR.

[0071] The NR system supports UE uplink positioning by sending positioning SRS.

[0072] When the UE enters the RRC deactivated state, the UE may still send periodic or semi-persistent positioning SRS according to the configuration of the network (NW) in the serving cell.

[0073] 1. Configuration of positioning SRS resource set and positioning resources.

[0074] In the serving cell, the SRS resource set and resources can be located through NW configuration.

[0075] Specifically, the nested format of the RRC signaling for locating the SRS resource set and resources can be implemented as the following IE:

[0076] The positioning SRS resource set includes power control parameters. The Path Loss-Reference Signal (PL-RS) serves as the UE's downlink measurement reference signal. It can be an SSB from the serving cell, an SSB from a non-serving cell, or a downlink Positioning Reference Signal (PRS).

[0077] The RRC IE for locating the SRS resource set can be implemented as the following IE:

[0078] For positioning SRS resources, they contain spatial relationship information (ie, uplink transmission beam direction).

[0079] The RRC IE for locating SRS resources can be implemented as the following IE:

[0080] On radio frequency FR2, the beam of the positioning SRS sent by the UE is directional. The positioning SRS beam can be configured using spatial relationship information, where the reference signal included in the spatial relationship information can be from either a serving cell or a non-serving cell.

[0081] The RRC IE for positioning the spatial relationship information of the SRS (i.e., the transmit beam) can be implemented as the following IE:

[0082] 1. Positioning SRS transmission.

[0083] The power control of the positioning SRS is specifically implemented as follows:

[0084] If the UE transmits SRS based on the configuration of SRS-PosResourceSet on the activated UL BWP b of the carrier f of the serving cell c, the UE sets the SRS transmission power P in the SRS transmission opportunity i to SRS,b,f,c (i,q s) is determined as (If a UE transmits SRS based on a configuration by SRS-PosResourceSet on active UL BWP b of carrier f of serving cell c, the UE determines the SRS transmission power in SRS transmission occasion i as):

[0085] in:

[0086] P SRS,b,f,c (i,q s ) and α SRS,b,f,c (q s ) are provided by p0-r16 and alpha-r16 respectively, for the active UL BWP b of carrier f serving cell c, SRS resource set q s Indicated by SRS-PosResourceSetId from SRS-PosResourceSet (P SRS,b,f,c (i,q s )andα SRS,b,f,c (q s )are provided by p0-r16and alpha-r16respectively,for active UL BWP b of carrier f of serving cell c,and SRS resource set q s is indicated by SRS-PosResourceSetId from SRS-PosResourceSet),and

[0087] PL b,f,c )(q d ) is the downlink path loss estimate in dB calculated by the UE, with active DL BWP in serving cell c, using SRS resource set q s RS resource index q in the serving or non-serving cell d (PL b,f,c )(q d)is a downlink pathloss estimate in dB calculated by the UE,in case of an active DL BWP of a serving cell c,using RS resource indexed q d in a serving or non-serving cell for SRS resource set q s ).

[0088] As can be seen, there are three main RRC configuration parameters for positioning SRS power control: P0 (target power reaching the receiving end), alpha (path loss impact factor) and PL (path loss, estimated by the received power of PL RS).

[0089] On FR2, there are three ways to transmit the SRS transmission beam:

[0090] Method 1: The NW configures the spatial relationship information of the positioning SRS resources for the UE. The spatial relationship information may include the following reference signals:

[0091] SSB of the serving cell, CSI-RS of the serving cell, SRS of the serving cell, or other positioning SRS of the serving cell;

[0092] SSB of non-serving cell;

[0093] PRS of serving cell or non-serving cell;

[0094] Method 2: The UE uses beam scanning to send positioning SRS resources. The multiple beam directions used are implemented by the UE itself, so the NW does not need to configure spatial relationship information for it.

[0095] Mode 3: The UE uses a fixed beam direction (applicable to FR1 and FR2). In order to improve the uplink coverage, a wide beam is often used in implementation.

[0096] (3) Paging in NR

[0097] The NW transmits paging DCI and scheduled PDSCH in DCI format 1_0 during the UE's paging occasion. The paging DCI carries a short message and scheduling information, and the PDSCH carries the paging message.

[0098] The following information is transmitted by means of the DCI format 1_0 with CRC scrambled by P-RNTI:

[0099] Short Messages Indicator–2 bits according to Table.

[0100] Short Messages–8 bits, according to Clause 6.5 of [9, TS38.331]. If only the scheduling information for Paging, and TRS availability indication if trs-ResourceSetConfig is configured, are carried, this bit field is reserved.

[0101] Frequency Domain Resource Allocation – If trs-ResourceSetConfig is configured to carry only short messages and TRS availability indication, this bit field is reserved (Frequency domain resource assignment bits.If only the short message,and TRS availability indication if trs-ResourceSetConfig is configured,are carried,this bit field is reserved). is the size of Control Resource Set (CORESET) 0 ( is the size of CORESET 0)

[0102] Time domain resource assignment – ​​4 bits as defined in Clause 5.1.2.1 of [6, TS38.214]. If only the short message, and TRS availability indication if trs-ResourceSetConfig is configured, are carried, this bit field is reserved.

[0103] VRB-to-PRB mapping – 1 bit according to Table 7.3.1.2.2-5. If only the short message and TRS availability indication if trs-ResourceSetConfig is configured, are carried, this bit field is reserved.

[0104] Modulation and Coding Scheme (MCS) – 5 bits, as defined in Clause 5.1.3 of [6, TS38.214], using Table 5.1.3.1-1. If only the short message and TRS availability indication if trs-ResourceSetConfig is configured, are carried, this bit field is reserved.

[0105] TB scaling – 2 bits as defined in Clause 5.1.3.2 of [6, TS38.214]. If only the short message, and TRS availability indication if trs-ResourceSetConfig is configured, are carried, this bit field is reserved.

[0106] TRS availability indication – 1, 2, 3, 4, 5, or 6 bits, where the number of bits is equal to one plus the highest value of all the indBitID(s) provided by the trs-ResourceSetConfig if configured; 0 bits otherwise.

[0107] Reserved bits–(8–M) bits for operation in a cell with shared spectrum channel access in frequency range 1 or for operation in a cell in frequency range 2-2; (6–M) bits for operation in a cell without shared spectrum channel access, where the value of M is the number of bits for the field of 'TRS availability indication' as defined above.

[0108] The following is an exemplary description of the 2 bits of the short message indication with reference to Table 1.

[0109] Table 1

[0110] As shown in Table 1, if the 2 bits of the short message indication are reserved bits, the 2 bits of the short message indication are 00; if only the scheduling information for paging and the TRS availability indication (if trs-ResourceSetConfig is configured) appear in the DCI, the 2 bits of the short message indication are 01; if only the short message and the TRS availability indication (if trs-ResourceSetConfig is configured) appear in the DCI, the 2 bits of the short message indication are 10; if the scheduling information for paging, the TRS availability indication (if trs-ResourceSetConfig is configured) and the short message all exist in the DCI, the 2 bits of the short message indication are 11.

[0111] Of course, Table 2 is merely an example of the present application and should not be construed as limiting the present application.

[0112] For example, in other alternative embodiments, the meanings of the two bits of the short message indication may be interchanged in pairs, or the reserved bits may be other bits.

[0113] The following is an exemplary description of the 8 bits of a short message with reference to Table 2.

[0114] Table 2

[0115] As shown in Table 2, if the first to fourth bits of the short message are used bits, the fifth to eighth bits are unused bits.

[0116] Of course, Table 2 is merely an example of the present application and should not be construed as limiting the present application.

[0117] For example, in other alternative embodiments, the meanings of the first to fourth bits of the short message may be interchanged in pairs, or the reserved bits may be other bits.

[0118] The following is an exemplary description of the format of a paging message.

[0119] The format of the paging message can be implemented as follows:

[0120] As can be seen from the above, the paging message includes the paging information of the NW to one or more UEs, and the core information includes the paging UE ID.

[0121] FIG3 is a schematic diagram of a UE positioning effective area provided in an embodiment of the present application.

[0122] As shown in Figure 3, TRP1 provides cells 1 and 5, TRP2 provides cells 2 and 4, and TRP3 provides cell 3. The effective positioning area of ​​the terminal device includes cells 1 to 3. When the terminal device moves in multiple cells with the Radio Resource Control (RRC) deactivated, if the terminal device sends the positioning sounding reference signal (SRS) configured according to the previous cell, due to improper use of the power parameters of the positioning SRS or improper uplink transmission beam, it may interfere with other cells in the effective positioning area or make the network device unable to normally estimate the positioning SRS sent by the terminal device, thereby affecting the positioning accuracy.

[0123] Therefore, when a terminal device moves in an RRC inactive state within the effective positioning area of ​​the terminal device and moves to a different cell and / or the coverage area of ​​a different beam, the terminal device needs to adjust the transmission power and the transmission beam direction of the positioning SRS. Typically, if a network device wants to reconfigure the positioning SRS of a terminal device, the terminal device needs to switch from an RRC deactivated state to an RRC connected state, which consumes a large amount of energy of the terminal device. For battery-powered terminal devices, especially Internet of Things (IoT) devices, this will reduce the battery life of the terminal device.

[0124] In view of this, the embodiments of the present application provide a configuration information switching method, a terminal device, and a network device, which can save the energy consumption of the terminal device, especially improve the battery life of the IoT device. In the embodiments of the present application, the terminal device can switch the positioning SRS configuration information used by the terminal device based on the downlink measurement results or the instructions of the network device. Furthermore, before the terminal device enters the RRC deactivated state, the network device can configure multiple positioning SRS configuration information for the terminal device through RRC signaling based on the downlink measurement capability reported by the terminal device; based on this, when the terminal device moves within the positioning effective area of ​​the terminal device, the terminal device can autonomously select the positioning SRS configuration information, as well as its configured power control parameters and spatial relationship information through the downlink measurement results; the network device can also activate or deactivate semi-continuous positioning SRS configuration information, or indicate non-periodic positioning SRS configuration information, thereby avoiding the terminal device switching the positioning SRS configuration information used by the terminal device by entering the RRC connected state, thereby saving unnecessary power overhead.

[0125] It should be understood that in the embodiment of the present application, the term "beam" can also be equivalently replaced by a spatial domain filter or can correspond to a spatial domain filter. For example, the transmit beam can be called a spatial domain transmission filter or can correspond to a spatial domain transmit filter, and the receive beam can be called a spatial domain receive filter or can correspond to a spatial domain receive filter. Of course, it can also be equivalently replaced with terms with similar meanings, and this application does not make specific restrictions on this. In addition, when the UE enters the RRC inactive state, it no longer distinguishes between serving cells and non-serving cells, and they are all referred to as cells.

[0126] FIG4 is a schematic flow chart of a configuration information switching method 200 provided in an embodiment of the present application. The method 200 may be executed by a terminal device. For example, the method 200 may be executed by the terminal device shown in FIG1 to FIG3.

[0127] As shown in FIG4 , the method 200 may include some or all of the following:

[0128] S210, the terminal device obtains first information;

[0129] The first information includes at least one of the following: a downlink measurement result and first indication information; the first indication information instructs the terminal device to switch positioning sounding reference signal (SRS) configuration information;

[0130] S220: The terminal device switches the positioning SRS configuration information used by the terminal device based on the first information.

[0131] Exemplarily, the downlink measurement result may be a measurement result obtained by the terminal device measuring a downlink reference signal.

[0132] Exemplarily, the downlink reference signal measured by the terminal device when obtaining the downlink measurement result may be a reference downlink reference signal from a cell corresponding to the positioning SRS configuration information used by the terminal device, or a reference downlink reference signal from a cell corresponding to the positioning SRS configuration information not used by the terminal device. The positioning SRS configuration information used by the terminal device may refer to the positioning SRS configuration information used by the terminal device when performing downlink measurement or obtaining the downlink measurement result, and the positioning SRS configuration information not used by the terminal device may refer to the positioning SRS configuration information not used by the terminal device when performing downlink measurement or obtaining the downlink measurement result.

[0133] Exemplarily, the downlink reference signal measured by the terminal device when obtaining the downlink measurement result may include at least one of the following: a path loss reference signal (PL-RS) associated with a positioning SRS resource set (e.g., a positioning SRS resource set configured by the positioning SRS configuration information used by the terminal device, or a positioning SRS resource set configured by the positioning SRS configuration information not used by the terminal device), and a downlink reference signal configured in the spatial relationship information associated with a positioning SRS resource (e.g., a positioning SRS resource configured by the positioning SRS configuration information used by the terminal device, or a positioning SRS resource configured by the positioning SRS configuration information not used by the terminal device). For example, the reference downlink reference signal from the cell corresponding to the positioning SRS configuration information used by the terminal device may include: a PL-RS associated with a positioning SRS resource set (e.g., a positioning SRS resource set configured by the positioning SRS configuration information used by the terminal device), and a downlink reference signal configured in the spatial relationship information associated with a positioning SRS resource (e.g., a positioning SRS resource configured by the positioning SRS configuration information used by the terminal device). The reference downlink reference signal from the cell corresponding to the positioning SRS configuration information not used by the terminal device may include: the PL-RS associated with the positioning SRS resource set (for example, the positioning SRS resource set configured by the positioning SRS configuration information not used by the terminal device), and the downlink reference signal configured in the spatial relationship information associated with the SRS resource (for example, the positioning SRS resource configured by the positioning SRS configuration information not used by the terminal device).

[0134] Among them, the PL-RS associated with the positioning SRS resource set (for example, the positioning SRS resource set configured by the positioning SRS configuration information used by the terminal device, or the positioning SRS resource set configured by the positioning SRS configuration information not used by the terminal device) includes but is not limited to: synchronization signal and / or physical broadcast channel block (Synchronization Signal / PBCH Block, SSB), positioning reference signal (Positioning Reference Signal, PRS), or other positioning SRS, etc. The downlink reference signal configured in the spatial relationship information associated with the positioning SRS resource (for example, the SRS resource configured by the positioning SRS configuration information used by the terminal device, or the positioning SRS resource configured by the positioning SRS configuration information not used by the terminal device) includes but is not limited to: synchronization signal and / or physical broadcast channel block (Synchronization Signal / PBCH Block, SSB), channel state information reference signal (CSI-RS), positioning reference signal (PRS), or other positioning SRS, etc.

[0135] Exemplarily, the first indication information may be information indicated by a network device.

[0136] Exemplarily, the first indication information may be used to trigger the terminal device to switch the positioning SRS configuration information, and may also be used to indicate the positioning SRS configuration information.

[0137] If the first indication information is used to trigger the terminal device to switch the positioning SRS configuration information, then when the terminal device receives the first indication information, it triggers the terminal device to switch the positioning SRS configuration information; in this case, the embodiment of the present application does not limit which positioning SRS configuration information the terminal device switches to. For example, the terminal device can switch between the configured positioning SRS configuration information in a traversal manner. For another example, the terminal device can switch the first downlink measurement information. For another example, the terminal device can switch the positioning SRS configuration information used by the terminal device to the positioning SRS configuration information further indicated by the network device. If the first indication information is used to indicate the positioning SRS configuration information used by the terminal device, then the terminal device can directly switch the positioning SRS configuration information used by the terminal device to the positioning SRS configuration information indicated by the terminal device.

[0138] Exemplarily, when the terminal device is in the RRC deactivated state, it can first obtain the first information, and then switch the positioning SRS configuration information used by the terminal device based on the first information.

[0139] In this embodiment, a terminal device obtains first information; wherein the first information includes at least one of the following: a downlink measurement result and first indication information; the first indication information instructs the terminal device to switch positioning SRS configuration information; and then, based on the first information, the positioning SRS configuration information used by the terminal device is switched. In this embodiment, by introducing the first information and switching the positioning SRS configuration information of the terminal device based on the first information, the terminal device avoids reconfiguring the SRS after switching from an RRC deactivated state to an RRC connected state, thereby saving energy consumption of the terminal device and, in particular, improving the battery life of the IoT device.

[0140] It is worth noting that the embodiments of the present application do not limit the specific content of the positioning SRS configuration information involved.

[0141] For example, the positioning SRS configuration information is used to configure at least one of the following information: an identifier of the positioning SRS, a positioning SRS for positioning the SRS, time-frequency domain resources for the positioning SRS, and power control parameters for the positioning SRS. The time-frequency domain resources of the positioning SRS include a positioning SRS resource set, and the positioning SRS resource set includes one or more positioning SRS resources. The power control parameters for the positioning SRS include at least one of the following: a target power (P0) arriving at the receiving end, a path loss impact factor (alpha), and a path loss (PL); the path loss (PL) is estimated by the received power of the PL-RS. Furthermore, the positioning SRS configuration information is used to configure spatial relationship information associated with the positioning SRS resources in the positioning SRS resource set.

[0142] In some embodiments, the first information includes the downlink measurement result.

[0143] Exemplarily, when a terminal device moves between different cells within a positioning effective area, if the terminal device is in an RRC deactivated state, the terminal device will not switch between cells, and the network device cannot use conventional signaling (such as RRC and / or MAC CE in an RRC linked state) to control which cell's positioning SRS the terminal device sends. In this embodiment, the terminal device can perform downlink measurements on the downlink reference signal (such as CSI-RS, SSB or PRS) contained in the PL RS and / or spatial relationship information, and obtain the downlink measurement results, and then autonomously select positioning SRS configuration information based on the downlink measurement results, and switch the positioning SRS configuration information used by the terminal device to the positioning SRS configuration information selected by the terminal device. The positioning SRS configuration information selected by the terminal device includes at least uplink spatial relationship information (such as spatial domain transmit filter) and uplink power control parameters, etc.

[0144] Exemplarily, the terminal device switches the positioning SRS configuration information used by the terminal device based on the downlink measurement result. For example, the terminal device measures a path loss reference signal (PL-RS) associated with a positioning SRS resource set (e.g., a positioning SRS resource set configured by the positioning SRS configuration information used by the terminal device, or a positioning SRS resource set configured by the positioning SRS configuration information not used by the terminal device), or a downlink reference signal configured in the spatial relationship information associated with a positioning SRS resource (e.g., a positioning SRS resource configured by the positioning SRS configuration information used by the terminal device, or a positioning SRS resource configured by the positioning SRS configuration information not used by the terminal device), and obtains a downlink measurement result; then, based on the downlink measurement result, switches the positioning SRS configuration information used by the terminal device.

[0145] Exemplarily, after the terminal device obtains the downlink measurement result, the behavior of the terminal device can be triggered by defining a trigger condition. Specifically, the terminal device measures the PL RS associated with the positioning SRS resource set of at least one cell or other downlink RS contained in the spatial relationship information of at least one cell in the RRC deactivated state to obtain the measurement result of the at least one cell, and switches the positioning SRS configuration information used by the terminal device based on the measurement result of the at least one cell. For example, when the measurement results of the multiple cells meet certain specific conditions (which can also be referred to as certain specific events), the terminal device can autonomously change the positioning SRS configuration information used. The autonomy mentioned here can be understood as the terminal device changing the positioning SRS configuration information used, and does not need to confirm with the network device or obtain permission from the network device.

[0146] In some embodiments, S220 may include:

[0147] When the downlink measurement result meets the triggering condition for switching the positioning SRS configuration information, the terminal device switches the positioning SRS configuration information used by the terminal device.

[0148] Exemplarily, the trigger condition may be a condition determined by the terminal device and notified to the network device, a condition determined by the network device and indicated to the terminal device, a condition determined by the terminal device and the network device through negotiation, or a predefined condition.

[0149] Among them, the predefined conditions can be implemented by pre-saving corresponding codes, tables or other methods that can be used to indicate relevant information in a device (for example, including a terminal device and a network device), and this application does not limit its specific implementation method. For example, the predefined conditions may refer to conditions defined in a protocol. It should also be understood that in the embodiments of the present application, the term "protocol" may refer to any standard protocol in the field of communications, for example, it may include LTE protocols, NR protocols, and related protocols used in future communication systems, and this application does not limit this.

[0150] Exemplarily, the trigger condition may be used to trigger the terminal device to switch the positioning SRS configuration information used by the terminal device.

[0151] In other words, after obtaining the downlink measurement result, the terminal device determines whether the trigger condition is met based on the downlink measurement result, and when the trigger condition is met, the terminal device switches the positioning SRS configuration information used by the terminal device. In other words, the trigger condition can be used to trigger the terminal device to switch the positioning SRS configuration information used by the terminal device.

[0152] Exemplarily, the trigger condition may be used to indicate to which positioning SRS configuration information the terminal device switches.

[0153] In other words, after obtaining the downlink measurement result, the terminal device determines whether the trigger condition is met based on the downlink measurement result, and when the trigger condition is met, the terminal device switches the positioning SRS configuration information used by the terminal device based on the trigger condition. In other words, the trigger condition can not only be used to trigger the terminal device to switch the positioning SRS configuration information used by the terminal device, but also be used to determine to which positioning SRS configuration information the terminal device switches the positioning SRS configuration information used by the terminal device.

[0154] It should be noted that the trigger condition can also be equivalently replaced by terms with similar meanings or functions, such as trigger events, and this application does not make specific limitations on this.

[0155] Taking a trigger event as an example, as an implementation method, after the terminal device obtains the measurement result, it determines whether the trigger event is met based on the measurement result, and when the trigger event is met, the terminal device switches the positioning SRS configuration information used by the terminal device. In other words, the trigger event can be used to trigger the terminal device to switch the positioning SRS configuration information used by the terminal device, or in other words, the terminal device switches the positioning SRS configuration information used by the terminal device based on an event trigger. As another implementation method, after the terminal device obtains the measurement result, it determines whether the trigger event is met based on the measurement result, and when the trigger event is met, the terminal device switches the positioning SRS configuration information used by the terminal device based on the trigger event. In other words, the trigger event can not only be used to trigger the terminal device to switch the positioning SRS configuration information used by the terminal device, but also be used to determine to which positioning SRS configuration information the terminal device switches the positioning SRS configuration information used by the terminal device.

[0156] In some embodiments, if the measurement result of the first downlink reference signal corresponding to the first positioning SRS configuration information used by the terminal device meets the first condition in the trigger condition, the terminal device is triggered to switch the positioning SRS configuration information used by the terminal device.

[0157] Exemplarily, the downlink measurement result includes a measurement result of the first downlink reference signal.

[0158] Exemplarily, the terminal device obtains a measurement result of the first downlink reference signal (i.e., the downlink reference signal corresponding to the first positioning SRS configuration information used by the terminal device) by measuring the first downlink reference signal, and then determines whether the measurement result of the first downlink reference signal meets the first condition in the trigger condition, and when the measurement result of the first downlink reference signal meets the first condition, triggers the terminal device to switch the positioning SRS configuration information used by the terminal device, that is, switches the positioning SRS configuration information used by the terminal device from the first positioning SRS configuration information to other configured positioning SRS configuration information. In other words, the first condition can be used to trigger the terminal device to switch the positioning SRS configuration information used by the terminal device.

[0159] In this embodiment, by introducing the measurement result of the first downlink reference signal, and when the measurement result of the first downlink reference signal meets the first condition in the trigger condition, the terminal device is triggered to switch the positioning SRS configuration information used by the terminal device. This is equivalent to triggering the terminal device to switch the positioning SRS configuration information used by the terminal device from the first positioning SRS configuration information to other configured positioning SRS configuration information by judging whether the measurement result of the first downlink reference signal corresponding to the first positioning SRS configuration information meets the first condition, thereby improving the switching effect of the positioning SRS configuration information.

[0160] It should be noted that the first condition can also be equivalently replaced by terms with similar meanings or functions, such as the first event, and this application does not make specific limitations on this.

[0161] Taking the first event as an example, after the terminal device obtains the measurement result of the first reference signal, it determines whether the first event is satisfied based on the measurement result of the first reference signal. When the measurement result of the first reference signal satisfies the first event, the terminal device switches the positioning SRS configuration information used by the terminal device. In other words, the first event can be used to trigger the terminal device to switch the positioning SRS configuration information used by the terminal device, or in other words, the switching of the positioning SRS configuration information used by the terminal device is triggered based on the first event.

[0162] In some embodiments, when the information configured by the first positioning SRS configuration information includes a first positioning SRS resource set, the first downlink reference signal includes: a PL-RS associated with the first positioning SRS resource set.

[0163] Exemplarily, the PL-RS associated with the first positioning SRS resource set includes, but is not limited to: SSB, PRS, or other positioning SRS.

[0164] In other words, the PL-RS (such as SSB, PRS, or other positioning SRS) associated with the first positioning SRS resource set (i.e., the positioning SRS resource set configured by the first positioning SRS configuration information used by the terminal device) can be used as the first reference signal. In other words, the terminal device can obtain the measurement result of the first downlink reference signal by measuring the PL-RS (such as SSB, PRS, or other positioning SRS) associated with the first positioning SRS resource set (i.e., the positioning SRS resource set configured by the first positioning SRS configuration information used by the terminal device), and trigger the terminal device to switch the positioning SRS configuration information used by the terminal device when the measurement result of the first downlink reference signal meets the first condition.

[0165] In some embodiments, when the information configured by the first positioning SRS configuration information includes a first positioning SRS resource, the first downlink reference signal includes: a downlink reference signal configured in the spatial relationship information associated with the first positioning SRS resource.

[0166] Exemplarily, the downlink reference signal configured in the spatial relationship information associated with the first positioning SRS resource includes, but is not limited to: SSB, PRS, CSI-RS, or other positioning SRS.

[0167] In other words, the downlink reference signal configured in the spatial relationship information associated with the first positioning SRS resource (i.e., the positioning SRS resource configured by the first positioning SRS configuration information used by the terminal device) can be used as the first reference signal. In other words, the terminal device can obtain the measurement result of the first downlink reference signal by measuring the downlink reference signal (such as SSB, PRS, CSI-RS, or other positioning SRS) configured in the spatial relationship information associated with the first positioning SRS resource (i.e., the positioning SRS resource configured by the first positioning SRS configuration information used by the terminal device), and trigger the terminal device to switch the positioning SRS configuration information used by the terminal device when the measurement result of the first downlink reference signal meets the first condition.

[0168] In some embodiments, the first condition includes at least one of the following: signal quality of the first downlink reference signal is less than or equal to a first threshold, and fluctuation of the signal quality of the first downlink reference signal is greater than or equal to a second threshold.

[0169] Exemplarily, the signal quality of the first downlink reference signal includes but is not limited to:

[0170] Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), and Carrier to Interference plus Noise Ratio (SR-SINR).

[0171] Exemplarily, the signal quality of the first downlink reference signal is less than or equal to the first threshold value, indicating that the signal quality of the PL RS of the positioning SRS resource set or the DL RS in the spatial relationship information currently being used by the terminal device is too low, that is, the terminal device needs to switch the positioning SRS configuration information currently being used by the terminal device; similarly, the fluctuation of the signal quality of the first downlink reference signal is greater than or equal to the second threshold value, indicating that the signal fluctuation of the PL RS of the positioning SRS resource set or the DL RS in the spatial relationship information currently being used by the terminal device is too large, that is, the terminal device needs to switch the positioning SRS configuration information currently being used by the terminal device; in this case, triggering the terminal device to switch the positioning SRS configuration information used by the terminal device is conducive to the terminal device using positioning SRS configuration information with better performance to send the positioning SRS, thereby improving the signal quality of the positioning SRS.

[0172] Exemplarily, the first threshold value may be other values ​​such as 18dB or 24dB.

[0173] Exemplarily, the second threshold value may be other values ​​such as 6dB or 12dB.

[0174] Exemplarily, the fluctuation of the signal quality of the first downlink reference signal may be the absolute value of the difference between at least two previous and subsequent measurement values ​​of the terminal device.

[0175] Exemplarily, the first condition includes: signal quality of the first downlink reference signal is less than or equal to a first threshold.

[0176] In other words, the terminal device obtains the measurement result of the first downlink reference signal by measuring the first downlink reference signal, and when the signal quality of the first downlink reference signal is less than or equal to the first threshold value, triggers the terminal device to switch the positioning SRS configuration information used by the terminal device.

[0177] Exemplarily, the first condition includes: a fluctuation in the signal quality of the first downlink reference signal is greater than or equal to a second threshold.

[0178] In other words, the terminal device obtains the measurement result of the first downlink reference signal by measuring the first downlink reference signal, and when the fluctuation of the signal quality of the first downlink reference signal is greater than or equal to the second threshold value, triggers the terminal device to switch the positioning SRS configuration information used by the terminal device.

[0179] Exemplarily, the first condition includes: the signal quality of the first downlink reference signal is less than or equal to a first threshold, and the fluctuation of the signal quality of the first downlink reference signal is greater than or equal to a second threshold.

[0180] In other words, the terminal device obtains the measurement result of the first downlink reference signal by measuring the first downlink reference signal, and when the signal quality of the first downlink reference signal is less than or equal to the first threshold value and the fluctuation of the signal quality of the first downlink reference signal is greater than or equal to the second threshold value, the terminal device is triggered to switch the positioning SRS configuration information used by the terminal device.

[0181] Exemplarily, the first threshold value and / or the second threshold value can be a threshold value determined by the terminal device and notified to the network device, or a threshold value determined by the network device and indicated to the terminal device, or a threshold value determined by the terminal device and the network device through negotiation, or a predefined threshold value.

[0182] Among them, the predefined threshold value can be implemented by pre-saving the corresponding code, table or other methods that can be used to indicate relevant information in the device (for example, including terminal devices and network devices), and this application does not limit its specific implementation method. For example, the predefined threshold value may refer to a threshold value defined in the protocol. It should also be understood that in the embodiments of the present application, the term "protocol" may refer to any standard protocol in the field of communications, for example, it may include LTE protocol, NR protocol and related protocols used in future communication systems, and this application does not limit this.

[0183] In some embodiments, the terminal device is configured with unused second positioning SRS configuration information; if the measurement result of the second downlink reference signal corresponding to the second positioning SRS configuration information meets the second condition in the trigger condition, the positioning SRS configuration information used by the terminal device is switched to the second positioning SRS configuration information.

[0184] Exemplarily, the downlink measurement result includes a measurement result of the second downlink reference signal.

[0185] Exemplarily, the terminal device obtains a measurement result of the second downlink reference signal by measuring the second downlink reference signal (i.e., the downlink reference signal corresponding to the second positioning SRS configuration information not used by the terminal device), and then determines whether the measurement result of the second downlink reference signal meets the second condition in the trigger condition, and when the measurement result of the second downlink reference signal meets the second condition, switches the positioning SRS configuration information used by the terminal device to the second positioning SRS configuration information. In other words, the second condition can not only be used to trigger the terminal device to switch the positioning SRS configuration information used by the terminal device, but also to determine which positioning SRS configuration information the terminal device switches to.

[0186] In this embodiment, by introducing the measurement result of the second downlink reference signal, and when the measurement result of the second downlink reference signal meets the second condition in the trigger condition, the positioning SRS configuration information used by the terminal device is switched to the second positioning SRS configuration information. This is equivalent to determining whether the positioning SRS configuration information used by the terminal device is switched to the second positioning SRS configuration information by judging whether the measurement result of the second downlink reference signal corresponding to the second positioning SRS configuration information meets the second condition, thereby improving the switching effect of the positioning SRS configuration information.

[0187] It should be noted that the second condition can also be equivalently replaced by a term with similar meaning or function, such as a second event, and this application does not make any specific limitations on this.

[0188] Taking the second event as an example, after the terminal device obtains the measurement result of the second reference signal corresponding to the second positioning SRS configuration information, it determines whether the second event is satisfied based on the measurement result of the second reference signal, and when the measurement result of the second reference signal satisfies the second event, the terminal device switches the positioning SRS configuration information used by the terminal device to the second positioning SRS configuration information. In other words, the second event can not only be used to trigger the terminal device to switch the positioning SRS configuration information used by the terminal device, but also to determine which positioning SRS configuration information the terminal device switches to.

[0189] In some embodiments, when the information configured by the second positioning SRS configuration information includes a second positioning SRS resource set, the second downlink reference signal includes: a path loss reference signal PL-RS associated with the second positioning SRS resource set.

[0190] Exemplarily, the PL-RS associated with the second positioning SRS resource set includes, but is not limited to: SSB, PRS, or other positioning SRS.

[0191] In other words, the PL-RS (such as SSB, PRS, or other positioning SRS) associated with the second positioning SRS resource set (i.e., the positioning SRS resource set configured by the second positioning SRS configuration information not used by the terminal device) can be used as the second reference signal. In other words, the terminal device can obtain the measurement result of the second downlink reference signal by measuring the PL-RS (such as SSB, PRS, or other positioning SRS) associated with the second positioning SRS resource set (i.e., the positioning SRS resource set configured by the second positioning SRS configuration information not used by the terminal device), and when the measurement result of the second downlink reference signal meets the second condition, the positioning SRS configuration information used by the terminal device is switched to the second positioning SRS configuration information.

[0192] In some embodiments, when the information configured by the second positioning SRS configuration information includes a second positioning SRS resource, the second downlink reference signal includes: a downlink reference signal configured in the spatial relationship information associated with the second positioning SRS resource.

[0193] Exemplarily, the downlink reference signal configured in the spatial relationship information associated with the second positioning SRS resource includes, but is not limited to: SSB, PRS, CSI-RS, or other positioning SRS.

[0194] In other words, the downlink reference signal configured in the spatial relationship information associated with the second positioning SRS resource (i.e., the positioning SRS resource configured by the second positioning SRS configuration information not used by the terminal device) can be used as the second reference signal. In other words, the terminal device can obtain the measurement result of the second downlink reference signal by measuring the downlink reference signal (such as SSB, PRS, CSI-RS, or other positioning SRS) configured in the spatial relationship information associated with the second positioning SRS resource (i.e., the positioning SRS resource configured by the second positioning SRS configuration information not used by the terminal device), and when the measurement result of the second downlink reference signal meets the second condition, the positioning SRS configuration information used by the terminal device is switched to the second positioning SRS configuration information.

[0195] In some embodiments, the second condition includes at least one of the following: signal quality of the second downlink reference signal is greater than or equal to a third threshold, and fluctuation in signal quality of the second downlink reference signal is less than or equal to a fourth threshold.

[0196] Exemplarily, the signal quality of the second downlink reference signal includes but is not limited to:

[0197] Reference Signal Receiving Power (RSRP), Reference Signal Receiving Quality (RSRQ), and Carrier to Interference plus Noise Ratio (SR-SINR).

[0198] Exemplarily, the signal quality of the second downlink reference signal is greater than or equal to the third threshold value, indicating that the signal quality of the PL RS of the second positioning SRS resource set or the DL RS in the spatial relationship information associated with the second positioning SRS resource can meet the sending requirement of the positioning SRS, that is, the terminal device can switch the positioning SRS configuration information used by the terminal device to the second positioning SRS configuration information used to configure the second positioning SRS resource set or the second positioning SRS resource; similarly, the fluctuation of the signal quality of the second downlink reference signal is less than or equal to the fourth threshold value, indicating that the signal fluctuation of the PL RS of the second positioning SRS resource set or the DL RS in the spatial relationship information associated with the second positioning SRS resource can meet the sending requirement of the positioning SRS, that is, the terminal device can switch the positioning SRS configuration information used by the terminal device to the second positioning SRS configuration information used to configure the second positioning SRS resource set or the second positioning SRS resource, so that the terminal device can use the positioning SRS configuration information with better performance to send the positioning SRS and improve the signal quality of the positioning SRS.

[0199] Exemplarily, the third threshold value may be other values ​​such as 18dB or 24dB.

[0200] Exemplarily, the fourth threshold value may be other values ​​such as 6dB or 12dB.

[0201] Exemplarily, the fluctuation of the signal quality of the second downlink reference signal may be the absolute value of the difference between at least two previous and subsequent measurement values ​​of the terminal device.

[0202] Exemplarily, the second condition includes: the signal quality of the second downlink reference signal is greater than or equal to a third threshold.

[0203] In other words, the terminal device obtains the measurement result of the second downlink reference signal by measuring the second downlink reference signal, and when the signal quality of the second downlink reference signal is greater than or equal to the third threshold value, switches the positioning SRS configuration information used by the terminal device to the second positioning SRS configuration information.

[0204] Exemplarily, the second condition includes: fluctuation in signal quality of the second downlink reference signal is less than or equal to a fourth threshold.

[0205] In other words, the terminal device obtains the measurement result of the second downlink reference signal by measuring the second downlink reference signal, and when the fluctuation of the signal quality of the second downlink reference signal is less than or equal to the fourth threshold value, the positioning SRS configuration information used by the terminal device is switched to the second positioning SRS configuration information.

[0206] Exemplarily, the second condition includes: the signal quality of the second downlink reference signal is greater than or equal to a third threshold, and the fluctuation of the signal quality of the second downlink reference signal is less than or equal to a fourth threshold.

[0207] In other words, the terminal device obtains a measurement result of the second downlink reference signal by measuring the second downlink reference signal, and when the signal quality of the second downlink reference signal is greater than or equal to the third threshold value and the fluctuation of the signal quality of the second downlink reference signal is less than or equal to the fourth threshold value, the positioning SRS configuration information used by the terminal device is switched to the second positioning SRS configuration information.

[0208] Exemplarily, the third threshold value and / or the fourth threshold value can be a threshold value determined by the terminal device and notified to the network device, or a threshold value determined by the network device and indicated to the terminal device, or a threshold value determined by the terminal device and the network device through negotiation, or a predefined threshold value.

[0209] Among them, the predefined threshold value can be implemented by pre-saving the corresponding code, table or other methods that can be used to indicate relevant information in the device (for example, including terminal devices and network devices), and this application does not limit its specific implementation method. For example, the predefined threshold value may refer to a threshold value defined in the protocol. It should also be understood that in the embodiments of the present application, the term "protocol" may refer to any standard protocol in the field of communications, for example, it may include LTE protocol, NR protocol and related protocols used in future communication systems, and this application does not limit this.

[0210] It should be noted that the above defines the first condition as the trigger condition from the perspective of "used to trigger the terminal device to switch the positioning SRS configuration information used by the terminal device", and the terminal device uses the first condition alone to trigger the terminal device to switch the positioning SRS configuration information used by the terminal device. On the other hand, the above defines the second condition from the perspective of "used to indicate which positioning SRS configuration information the terminal device switches to", and the terminal device uses the second condition alone to switch the positioning SRS configuration information used by the terminal device to the positioning SRS configuration information that is not used by the terminal device and whose corresponding reference signal measurement result meets the second condition. However, in other alternative embodiments, the terminal device may also switch the positioning SRS configuration information used by the terminal device in combination with the first condition and the second condition.

[0211] In some embodiments, if the measurement result of the first downlink reference signal corresponding to the first positioning SRS configuration information used by the terminal device meets the first condition in the trigger condition, and the measurement quality of the second downlink reference signal corresponding to the second positioning SRS configuration information not used by the terminal device meets the first condition in the trigger condition, the positioning SRS configuration information used by the terminal device is switched to the second positioning SRS configuration information.

[0212] Specifically, in combination with the example of the first condition and the example of the second condition, the following nine situations may be included:

[0213] Case 1:

[0214] The first condition includes: the signal quality of the first downlink reference signal is less than or equal to a first threshold value; the second condition includes: the signal quality of the second downlink reference signal is greater than or equal to a third threshold value.

[0215] In other words, the terminal device obtains the measurement result of the first downlink reference signal by measuring the first downlink reference signal, and obtains the measurement result of the second downlink reference signal by measuring the second downlink reference signal. If the signal quality of the first downlink reference signal is less than or equal to the first threshold value, and the signal quality of the second downlink reference signal is greater than or equal to the third threshold value, the terminal device switches the positioning SRS configuration information used by the terminal device to the second positioning SRS configuration information.

[0216] Case 2:

[0236] In other words, the terminal device obtains the measurement result of the first downlink reference signal by measuring the first downlink reference signal, and obtains the measurement result of the second downlink reference signal by measuring the second downlink reference signal. If the fluctuation of the signal quality of the first downlink reference signal is greater than or equal to the second threshold value, and the signal quality of the second downlink reference signal is greater than or equal to the third threshold value, and the fluctuation of the signal quality of the second downlink reference signal is less than or equal to the fourth threshold value, the terminal device switches the positioning SRS configuration information used by the terminal device to the second positioning SRS configuration information.

[0237] Case 9:

[0238] The first condition includes: the signal quality of the first downlink reference signal is less than or equal to the first threshold value, and the fluctuation of the signal quality of the first downlink reference signal is greater than or equal to the second threshold value; the second condition includes: the signal quality of the second downlink reference signal is greater than or equal to the third threshold value, and the fluctuation of the signal quality of the second downlink reference signal is less than or equal to the fourth threshold value.

[0239] In other words, the terminal device obtains the measurement result of the first downlink reference signal by measuring the first downlink reference signal, and obtains the measurement result of the second downlink reference signal by measuring the second downlink reference signal. If the signal quality of the first downlink reference signal is less than or equal to the first threshold value, and the fluctuation of the signal quality of the first downlink reference signal is greater than or equal to the second threshold value, and the signal quality of the second downlink reference signal is greater than or equal to the third threshold value, and the fluctuation of the signal quality of the second downlink reference signal is less than or equal to the fourth threshold value, then the terminal device can directly switch the positioning SRS configuration information used by the terminal device to the second positioning SRS configuration information.

[0240] Even in other alternative embodiments, the third condition may be constructed based on the first reference signal and the second reference signal. For example, the third condition may include: the difference obtained by subtracting the signal quality of the first reference signal from the signal quality of the second reference signal is greater than or equal to a fifth threshold value. As an implementation method, the third condition may be used alone, that is, the terminal device obtains the measurement result of the first downlink reference signal by measuring the first downlink reference signal, and obtains the measurement result of the second downlink reference signal by measuring the second downlink reference signal. If the difference obtained by subtracting the signal quality of the first reference signal from the signal quality of the second reference signal is greater than or equal to the fifth threshold value, the terminal device switches the positioning SRS configuration information used by the terminal device to the second positioning SRS configuration information. As another implementation method, the third condition can be used in combination with the first condition and / or the second condition; the third condition is used in combination with the first condition by the terminal device, and the first condition includes: the fluctuation of the signal quality of the first downlink reference signal is greater than or equal to the second threshold value; in this case, the terminal device obtains the measurement result of the first downlink reference signal by measuring the first downlink reference signal, and obtains the measurement result of the second downlink reference signal by measuring the second downlink reference signal, if the fluctuation of the signal quality of the first downlink reference signal is greater than or equal to the second threshold value, and the difference obtained by subtracting the signal quality of the second reference signal from the signal quality of the first reference signal is greater than or equal to the fifth threshold value, the terminal device switches the positioning SRS configuration information used by the terminal device to the second positioning SRS configuration information.

[0241] Exemplarily, the fifth threshold value may be other values ​​such as 9dB.

[0242] Exemplarily, the fifth threshold value may be a threshold value determined by the terminal device and notified to the network device, or a threshold value determined by the network device and indicated to the terminal device, or a threshold value determined by the terminal device and the network device through negotiation, or a predefined threshold value.

[0243] Among them, the predefined threshold value can be implemented by pre-saving the corresponding code, table or other methods that can be used to indicate relevant information in a device (for example, including a terminal device and a network device). This application does not limit its specific implementation method. For example, the predefined threshold value may refer to a threshold value defined in a protocol. It should also be understood that in the embodiments of the present application, the term "protocol" may refer to any standard protocol in the field of communications, for example, it may include an LTE protocol, an NR protocol, and related protocols used in future communication systems, and this application does not limit this.

[0244] In some embodiments, the first information includes the first indication information.

[0245] Exemplarily, the terminal device receives the first indication information and switches the positioning SRS configuration information used by the terminal device based on the first indication information.

[0246] In other words, the network device determines whether to adjust the positioning SRS configuration information (such as positioning SRS resources / resource sets) by measuring the positioning SRS sent by the terminal device. If necessary, the network device can notify the terminal device to make adjustments through the first indication information. Specifically, when the terminal device moves within a cell within the positioning validity area, one or more cells can receive the positioning SRS sent by the terminal device. Thus, the network device can determine whether the positioning SRS configuration information currently being used by the terminal device is appropriate, such as if the RSRP of the received SRS resources is too low. If the network device believes that the positioning SRS configuration information being used by the terminal device is no longer appropriate, the first indication information can be used to instruct the terminal device to adjust the positioning SRS configuration information being used.

[0247] In some embodiments, the first indication information includes at least one of the following: deactivation indication information and activation indication information; wherein, the deactivation indication information indicates the semi-persistent positioning SRS configuration information deactivated by the terminal device; the activation indication information indicates the semi-persistent positioning SRS configuration information activated by the terminal device.

[0248] For example, the semi-persistent positioning SRS configuration information involved in this application may also be referred to as semi-static positioning SRS configuration information.

[0249] Exemplarily, if the terminal device is configured with multiple semi-continuous positioning SRS configuration information, the terminal device can deactivate the semi-continuous positioning SRS configuration information indicated by the deactivation indication information through the deactivation indication information in the first indication information, and can also activate the semi-continuous positioning SRS configuration information indicated by the activation indication information through the activation indication information in the first indication information. The multiple semi-continuous positioning SRS configuration information include the semi-continuous positioning SRS configuration information indicated by the deactivation indication information and the semi-continuous positioning SRS configuration information indicated by the activation indication information. For example, the first indication information can include the deactivation indication information and the activation indication information at the same time. At this time, the terminal device can switch the semi-continuous positioning SRS configuration information used by the terminal device from the semi-continuous positioning SRS configuration information indicated by the deactivation indication information to the semi-continuous positioning SRS configuration information indicated by the activation indication information based on the deactivation indication information and the activation indication information.

[0250] In some embodiments, the first indication information is carried in a Media Access Control (MAC) Control Element (CE).

[0251] Of course, in other alternative embodiments, the first indication information may also be carried in any message that can be received by the terminal device in the RRC deactivated state, and this application does not make specific limitations on this.

[0252] In some embodiments, the first indication information indicates the non-periodic positioning SRS configuration information used by the terminal device.

[0253] Exemplarily, the non-periodic positioning SRS configuration information may also be referred to as dynamic positioning SRS configuration information.

[0254] Exemplarily, if the terminal device is configured with multiple non-periodic positioning SRS configuration information, the terminal device can switch the semi-continuous positioning SRS configuration information used by the terminal device to the non-periodic positioning SRS configuration information indicated by the first indication information based on the first indication information.

[0255] In some embodiments, the first indication information indicates, through the trigger state, that the positioning SRS configuration information used by the terminal device is the non-periodic positioning SRS configuration information associated with the trigger state.

[0256] Exemplarily, the terminal device is configured with multiple trigger states and multiple non-periodic positioning SRS configuration information corresponding to the multiple trigger states. The correspondence between the multiple trigger states and the multiple non-periodic positioning SRS configuration information can be a one-to-one correspondence. Specifically, if the terminal device is configured with multiple trigger states and multiple non-periodic positioning SRS configuration information corresponding to the multiple trigger states, then after the terminal device receives the first indication information sent by the network device, the semi-continuous positioning SRS configuration information used by the terminal device can be switched to the non-periodic positioning SRS configuration information corresponding to the trigger state indicated by the first indication information based on the first indication information.

[0257] In this embodiment, the first indication information is used to trigger the terminal device to switch the non-periodic positioning SRS configuration information used by the terminal device. For example, the first indication information can dynamically provide the terminal device with a trigger state of the non-periodic positioning SRS configuration information. Thus, the terminal device can send the positioning SRS according to the non-periodic positioning SRS resources included in the pre-configured trigger state to minimize the power consumption of the terminal device.

[0258] In some embodiments, the first indication information is carried in a physical downlink shared channel (PDSCH) scheduled by paging downlink control information (DCI).

[0259] Considering that the terminal device is in the RRC deactivated state, there are not many signaling means available. In this embodiment, the PDSCH scheduled by the paging DCI is used to notify the terminal device to switch the positioning SRS configuration information used by the terminal device (for example, positioning SRS resources / resource sets). Of course, in other alternative embodiments, the first indication information can also be carried in any message that can be received by the terminal device in the RRC deactivated state, and this application does not make specific limitations on this.

[0260] In other words, the network device can instruct the terminal device to adjust the sending of the positioning SRS in the RRC non-activated state through the first indication information. Specifically, the network device can carry the first indication information in the PDSCH scheduled by the paging DCI, and the first indication information instructs the terminal device to adjust the positioning SRS. For example, the terminal device is pre-configured with positioning SRS configuration information corresponding to multiple PCIs within the positioning effective area of ​​the terminal device. If the positioning SRS configuration information corresponding to the multiple PCIs includes configuration information specific to each of the multiple PCIs, the terminal device can be instructed to switch the positioning SRS configuration information to be used to the positioning SRS configuration information corresponding to other PCIs or other positioning SRS configuration information corresponding to the current PCI through the first indication information; if the positioning SRS configuration information corresponding to the multiple PCIs includes some configuration information common to the multiple PCIs and some configuration information specific to each of the multiple PCIs, the network device can instruct the terminal device to switch to other PCI-specific configuration information or other specific configuration information corresponding to the current PCI through the first indication information, such as instructing the terminal device to adjust the power control parameters (such as PL RS) of the positioning SRS resource set, and spatial relationship information of the positioning SRS resources.

[0261] It should be noted that if the positioning SRS configuration information corresponding to the multiple PCIs includes the multiple common configuration information, since there is only one common positioning SRS configuration information, there is no need for the network device to instruct the positioning SRS to be adjusted. Of course, if the terminal device receives the first indication information, the terminal device can stop sending the positioning SRS or ignore the first indication information.

[0262] In some embodiments, the PDSCH carries a paging message, which is not used to trigger the terminal device to switch from a radio resource control RRC deactivated state to an RRC connected state.

[0263] Exemplarily, if the first indication information is carried in the PDSCH scheduled by the paging DCI, the paging message in the PDSCH will not trigger the terminal device in the RRC inactive state to attempt to recover to the RRC connected state, but will continue to be in the RRC inactive state and continue to try to send the positioning SRS, saving the most energy while meeting the positioning requirements. In other words, for the terminal device, if the PDSCH scheduled by the paging DCI includes both the paging message and the first indication information, the paging message is not used to trigger the terminal device to switch from the radio resource control RRC deactivated state to the RRC connected state; if the PDSCH scheduled by the paging DCI includes a paging message but does not include the first indication information, the paging message is used to trigger the terminal device to switch from the radio resource control RRC deactivated state to the RRC connected state.

[0264] In some embodiments, when the paging message includes identifiers of multiple terminal devices, the paging message also includes: information for indicating a terminal device among the multiple terminal devices that switches positioning SRS configuration information.

[0265] Since the paging message may contain one or more UE ID(s); if the paging message contains only one UE ID, then the UE to which the paging information points is determined; if the paging message contains multiple UE IDs, and there is a UE among them that needs to adjust the configuration of the positioning SRS, then the network device needs to clearly indicate which UE (i.e., UE ID) it is, and the configuration of the positioning SRS needs to be adjusted (for example, the configuration of the positioning SRS needs to be activated or deactivated, or the configuration of the non-periodic positioning SRS needs to be switched). In this embodiment, the information of the UE indicating that the configuration of the positioning SRS needs to be adjusted is carried in the paging message. Of course, in other alternative embodiments, the information of the UE indicating that the configuration of the positioning SRS needs to be adjusted (for example, the configuration of the positioning SRS needs to be activated or deactivated, or the configuration of the non-periodic positioning SRS needs to be switched) can also be carried in the data channel scheduled by the paging DCI, and this application does not make specific limitations on this.

[0266] Exemplarily, the information for indicating the terminal device that switches the positioning SRS configuration information among the multiple terminal devices may include multiple bits corresponding to the multiple terminal devices, wherein the value of a bit in the multiple bits indicates whether the corresponding terminal device is a terminal device that needs to switch the positioning SRS configuration information. For example, when the value of a bit in the multiple bits is 1, it indicates that the corresponding terminal device is a terminal device that needs to switch the positioning SRS configuration information; when the value of a bit in the multiple bits is 0, it indicates that the corresponding terminal device is a terminal device that does not need to switch the positioning SRS configuration information. For another example, when the value of a bit in the multiple bits is 1, it indicates that the corresponding terminal device is a terminal device that does not need to switch the positioning SRS configuration information; when the value of a bit in the multiple bits is 0, it indicates that the corresponding terminal device is a terminal device that needs to switch the positioning SRS configuration information.

[0267] The relationship between the paging DCI and the PDSCH and the carrying location of the first indication information are exemplarily described below with reference to the accompanying drawings.

[0268] FIG5 is an example of carrying the first indication information through paging DCI and PDSCH provided by an embodiment of the present application.

[0269] As shown in Figure 5, the terminal device may receive the PDSCH based on the scheduling of the paging DCI. The paging DCI may include a short message indication, a short message, and scheduling information, the scheduling information is used to schedule the PDSCH, the PDSCH may include a paging message and the first indication information, and the paging message may be RRC signaling.

[0270] Figure 6 is an example provided by an embodiment of the present application of a PDSCH scheduled by a paging DCI carrying first indication information, and the first indication information includes deactivation indication information and / or activation indication information.

[0271] As shown in Figure 6, the terminal device can receive the PDSCH based on the scheduling of the paging DCI. The paging DCI may include a short message indication, a short message, and scheduling information. The scheduling information is used to schedule the PDSCH. The PDSCH may include a paging message and the first indication information. The paging message may be RRC signaling. Furthermore, if the first indication information includes at least one of the following: deactivation indication information and activation indication information, the first indication information may be carried in the MAC CE within the PDSCH scheduled by the paging DCI.

[0272] FIG7 is an example of the first indication information carried in the MAC CE provided in an embodiment of the present application.

[0273] As shown in Figure 7, for the MAC CE in the PDSCH scheduled by the paging DCI, it may include A / D. Further, the MAC CE may also include the PCI for locating the SRS resource set, the BWP, R, S, C, SUL for locating the SRS resource set, the ID for locating the SRS resource set, and the spatial relationship of resource ID0 to resource ID M-1 spatial relationship.

If the C field is set to 0, this field also indicates the identity of the BWP, which contains the resource ID i The length of this field is 2 bits (Positioning SRS Resource Set's BWP ID:This field indicates a UL BWP as the codepoint of the DCI bandwidth part indicator field as specified in TS 38.212[9], which contains activated / deactivated SP Positioning SRS Resource Set.If the C field is set to 0,this field also indicates the identity of the BWP which contains all resources indicated by the Spatial Relation for Resource ID i fields,if present.The length of the field is 2 bits).

[0278] C: This field indicates that the resource ID i The octets of the resource PCI field and resource BWP ID field, including the spatial relationship field, are present, and the spatial relationship resource ID of DL-PRS or SSB i Except when A / D is set to 1, if this field is set to 1, it contains the resource ID i This field indicates whether the octets containing Resource PCI field(s)and Resource BWP ID field(s)within the field Spatial Relation for Resource ID are present; otherwise, if this field is set to 0, they do not exist.

When A / D is set to 0, this field is always set to 0 that they are not present).

[0279] SUL: This field indicates whether the MAC CE applies to the NUL carrier or SUL carrier configuration. This field is set to 1 to indicate that it applies to the SUL carrier configuration, and it is set to 0 to indicate that it applies to the NUL carrier configuration.

[0283] R: Reserved bit, set to 0 (R: Reserved bit, set to 0).

[0284] FIG8 is an example of an embodiment of the present application, in which a PDSCH scheduled by a paging DCI is carried and the first indication information indicates that the terminal device uses a non-periodic positioning SRS.

[0285] As shown in Figure 8, the terminal device can receive the PDSCH based on the scheduling of the paging DCI. The paging DCI may include a short message indication, a short message, and scheduling information, the scheduling information is used to schedule the PDSCH, the PDSCH may include a paging message and the first indication information, and the paging message may be RRC signaling. Furthermore, if the first indication information indicates the non-periodic positioning SRS configuration information used by the terminal device, the first indication information may be carried in at least one bit within the PDSCH scheduled by the paging DCI.

[0286] In some embodiments, the method 200 may further include:

[0287] Second indication information is received, where the second indication information indicates whether the PDSCH includes the first indication information.

[0288] Exemplarily, the terminal device receives the second indication information sent by the network device, and when the second indication information indicates that the PDSCH includes the first indication information, the terminal device obtains the first indication information by receiving the PDSCH.

[0289] Exemplarily, the second indication information can be indicated by one bit; for example, when the value of the one bit is 0, it indicates that the PDSCH includes the first indication information, and when the value of the one bit is 1, it indicates that the PDSCH includes the first indication information; for another example, when the value of the one bit is 1, it indicates that the PDSCH includes the first indication information, and when the value of the one bit is 0, it indicates that the PDSCH includes the first indication information.

[0290] In some embodiments, the second indication information is carried in the paging DCI.

[0291] Exemplarily, the terminal device first receives a paging DCI and obtains the second indication information in the paging DCI; if the second indication information indicates that the PDSCH scheduled by the paging DCI includes the first indication information, the terminal device obtains the first indication information by receiving the PDSCH.

[0292] The following is an exemplary description of the 8 bits of a short message with reference to Table 3.

[0293] Table 3

[0294] As shown in Table 3, the second indication information may be the defined SRS conversion in Table 3. Specifically, a new 1-bit indication field is added to the short message. This field may be optional for the terminal device, that is, only the terminal device that supports this function can interpret Bit 5. If this field is 1, it means that the data channel of the paging DCI scheduling contains an indication that the terminal device adjusts the positioning SRS configuration (for example, the configuration of the positioning SRS needs to be activated or deactivated or the configuration of the non-periodic positioning SRS needs to be switched); for terminal devices that do not support this function, Bit 5 can be ignored.

[0295] Of course, the definition of SRS conversion in Table 3 can also be replaced by other terms with similar meanings based on the configuration of the terminal device or the specific type of the first indication information, and this application does not make specific restrictions on this. For example, if the terminal device is pre-configured with multiple semi-persistent positioning SRS configuration information, then when the positioning SRS conversion is set to 1, it can be understood as: indicating the activation or deactivation of the semi-persistent positioning SRS configuration information (indication of semi-persistent positioning SRS activation or deactivation), at this time, the positioning SRS conversion can also be called a semi-persistent positioning SRS (SemiPersistentPositioningSRS) conversion indication; if the terminal device is configured with multiple non-periodic positioning SRS configuration information, then when the positioning SRS conversion is set to 1, it can be understood as: instructing the terminal device to switch the non-periodic positioning SRS configuration information, at this time, the positioning SRS conversion can also be called a non-periodic positioning SRS conversion indication.

[0296] Of course, Table 3 is merely illustrative of the present application and should not be construed as limiting the present application.

[0297] In some embodiments, the information configured by the terminal device based on the third positioning SRS configuration information after switching the first information includes a third positioning SRS resource set; the third positioning SRS resource set includes a third positioning SRS resource.

[0298] Exemplarily, the positioning SRS configuration information may be the second positioning SRS configuration information mentioned above, or the semi-continuous positioning SRS configuration information indicated by the activation indication information in the first indication information, or the non-periodic positioning SRS configuration information indicated by the first indication information.

[0299] Exemplarily, the third positioning SRS resource set may include only one third positioning SRS resource, or may include multiple third positioning SRS resources.

[0300] Exemplarily, it is assumed that the terminal device switches the positioning SRS configuration information used by the terminal device based on the first information. For example, the terminal device switches the positioning SRS configuration information used by the terminal device to the third positioning SRS configuration information, which includes the positioning SRS resource set and its associated uplink power control parameters (such as P0, alpha and PL RS). At this time, the terminal device can send a positioning SRS according to the third positioning SRS configuration information.

[0301] Of course, in other alternative embodiments, the terminal device may also choose to stop sending the positioning SRS after the switching fails or succeeds, so as to avoid unnecessary power consumption.

[0302] In some embodiments, the information configured by the third positioning SRS configuration information also includes spatial relationship information associated with the third positioning SRS resource; the method 200 may also include: if the third positioning SRS resource is associated with one spatial relationship information, then the spatial relationship information associated with the third positioning SRS resource used by the terminal device is determined as the spatial relationship information used by the terminal device; and / or, if the third positioning SRS resource is associated with at least two spatial relationship information, then based on the measurement results of at least one of the following reference signals, the spatial relationship information used by the terminal device in the at least two spatial relationship information is determined: the path loss reference signal PL-RS associated with the third positioning SRS resource set, and the reference signal configured in the at least two spatial relationship information.

[0303] Exemplarily, if the terminal device switches the positioning SRS configuration information used by the terminal device to the third positioning SRS configuration information, and the information configured by the third positioning SRS configuration information includes a third positioning SRS resource and spatial relationship information associated with the third positioning SRS resource, then the terminal device can determine the spatial relationship information used by the terminal device based on the number of spatial relationships associated with the third positioning SRS resource. Specifically, if the third positioning SRS resource is associated with one spatial relationship information, the spatial relationship information associated with the third positioning SRS resource used by the terminal device is determined as the spatial relationship information used by the terminal device; if the third positioning SRS resource is associated with at least two spatial relationship information, the spatial relationship information used by the terminal device in the at least two spatial relationship information is determined based on the measurement result of at least one of the following reference signals: the path loss reference signal PL-RS associated with the third positioning SRS resource set, and the reference signal configured in the at least two spatial relationship information.

[0304] In other words, the network device can consider the spatial relationship information of the third positioning SRS resource under the third positioning SRS resource set in advance, that is, the network device can pre-configure a spatial relationship information for each third positioning SRS resource through the third positioning SRS configuration information. In this case, the terminal device can select the corresponding spatial relationship information to send the positioning SRS according to the autonomously selected positioning SRS resource. However, if the network device is not sure about the movement trajectory of the terminal device, it is very likely that multiple (more than one) spatial relationship information will be configured for the third positioning SRS resource in the third positioning SRS configuration information. At this time, the terminal device can select a spatial relationship information with better performance based on the measurement of the downlink PL RS or the DL RS in the spatial relationship information. For example, the terminal device can determine the PL RS with the strongest RSRP or the DL RS in the spatial relationship information (for example, the spatial domain transmit filter corresponding to the spatial domain receive filter corresponding to the PL RS with the strongest RSRP or the DL RS in the spatial relationship information) as the spatial relationship information used by the terminal device (for example, the spatial domain transmit filter).

[0305] In some embodiments, the information configured by the third positioning SRS configuration information does not include spatial relationship information associated with the third positioning SRS resource; the method 200 may also include: determining the spatial relationship information used by the terminal device based on the measurement results of the path loss reference signal PL-RS associated with the third positioning SRS resource set.

[0306] Exemplarily, if the terminal device switches the positioning SRS configuration information used by the terminal device to the third positioning SRS configuration information, and the information configured by the third positioning SRS configuration information includes a third positioning SRS resource and does not include spatial relationship information associated with the third positioning SRS resource, then the terminal device can determine the spatial relationship information used by the terminal device based on the measurement result of the path loss reference signal PL-RS associated with the third positioning SRS resource set. Specifically, the terminal device can determine the spatial relationship information of the PL-RS with the best performance as the spatial relationship information used by the terminal device based on the measurement result of the path loss reference signal PL-RS associated with the third positioning SRS resource set.

[0307] In other words, when the spatial filter used by the terminal device is a fixed wide spatial filter (also called a wide beam) or the spatial filter is determined in a scanning manner, the terminal device can also select a suitable spatial filter scanning direction (also called a beam scanning direction) or a fixed wide spatial filter (also called a wide beam) to send a positioning SRS through the measurement of the PL RS. How the terminal device selects can belong to the implementation of the UE. For example, for the PL RS selected by the terminal device, there will be a corresponding spatial receive filter. When sending the uplink positioning SRS, the terminal device uses the fixed wide spatial transmit filter (also called a wide beam) corresponding to the spatial receive filter, or performs a finer-grained spatial transmit filter scan (also called transmit beam scanning) on ​​the corresponding spatial transmit filter to send the same positioning SRS.

[0308] In some embodiments, the information configured by the third positioning SRS configuration information further includes: an identifier of the positioning SRS, time-frequency domain resources of the positioning SRS, and power control parameters for the positioning SRS.

[0309] Exemplarily, the third positioning SRS configuration information is used to configure at least one of the following information: an identifier of the positioning SRS, a positioning SRS for the positioning SRS, time-frequency domain resources for the positioning SRS, and power control parameters for the positioning SRS. The time-frequency domain resources of the positioning SRS include a positioning SRS resource set, and the positioning SRS resource set includes one or more positioning SRS resources. The power control parameters for the positioning SRS include at least one of the following: a target power (P0) reaching the receiving end, a path loss impact factor (alpha), and a path loss (PL); the path loss (PL) is estimated by the received power of the PL-RS. Further, the positioning SRS configuration information is used to configure spatial relationship information associated with the positioning SRS resources in the positioning SRS resource set.

[0310] In some embodiments, before S220, the method 200 may further include:

[0311] Acquire pre-configuration information for configuring multiple positioning SRS configuration information; wherein S220 may include:

[0312] Based on the first information, the positioning SRS configuration information used by the terminal device is switched among the multiple positioning SRS configuration information.

[0313] Exemplarily, the terminal device can obtain pre-configuration information in the RRC connected state, so that when the terminal device is in the RRC deactivated state, based on receiving the first information, and based on the first information, the terminal device switches the positioning SRS configuration information used by the terminal device between multiple SRS configuration information pre-configured by the pre-configuration information.

[0314] In some embodiments, the multiple positioning SRS configuration information includes positioning SRS configuration information corresponding to multiple cells within the effective positioning area of ​​the terminal device, and the positioning SRS configuration information corresponding to each cell in the multiple cells includes at least one positioning SRS configuration information.

[0315] Exemplarily, the pre-configuration information includes positioning SRS configuration information configured by the network device for multiple cells within the positioning effective area of ​​the terminal device. Each cell has a PCI that is different from other cells. Specifically, before the terminal device enters the RRC deactivated state, the network device can configure the positioning SRS resource sets of multiple cells within the positioning effective area (including N>=1 cells) and the positioning SRS resources in the positioning SRS resource set for the terminal device through pre-configuration information (such as RRC signaling). For the specific configuration method, please refer to the description of the "Configuration of Positioning SRS Resource Sets and Positioning Resources" section above.

[0316] Exemplarily, the relationship between the multiple cells and the multiple positioning SRS configuration information may be a one-to-one correspondence, a one-to-many relationship, or a many-to-one relationship.

[0317] In some embodiments, the pre-configuration information includes positioning SRS configuration information specific to each of the multiple cells.

[0318] In other words, the relationship between the multiple cells and the multiple positioning SRS configuration information is a one-to-one correspondence.

[0319] In some embodiments, the positioning SRS configuration information specific to each cell further includes the uplink bandwidth part BWP of each cell.

[0320] Exemplarily, the pre-configuration information can refer to the description of the “Positioning SRS Resource Set and Positioning Resource Configuration” section above, except that the network device needs to separately configure the corresponding configuration information for multiple cells (e.g., N cells) within the positioning effective area of ​​the terminal device. The RRC IE is exemplified as follows:

[0321] ValidityRegionCells includes maxNrofPCI cells, and CellInValidityRegion includes the positioning SRS configuration information of each cell in ValidityRegionCells, which is used to configure BWP-Id and SRS-Config. In addition, it should be noted that SRS-Config can only include the IE for positioning SRS, not the IE for regular SRS.

[0322] In this embodiment, for each PCI within the positioning effective area of ​​the terminal device, the positioning SRS configuration information may be configuration information for the uplink BWP (which may be a default BWP, an initial BWP, or a BWP specified by the network device). It should be noted that, in order to facilitate the terminal device to send the positioning SRS on the BWP and the network device to measure the positioning SRS, the BWP configurations of each cell in the multiple cells may completely overlap or partially overlap. For example, the BWP configurations of each cell in the multiple cells may partially overlap in the frequency domain resources occupied by the positioning SRS.

[0323] In some embodiments, the pre-configuration information includes positioning SRS configuration information common to the multiple cells.

[0324] Exemplarily, the relationship between the multiple cells and the multiple positioning SRS configuration information is a many-to-one relationship.

[0325] In this embodiment, the pre-configuration information includes the common positioning SRS configuration information of the multiple cells, which is equivalent to configuring the common positioning SRS resources or resource sets within the positioning effective area of ​​the terminal device for the terminal device, which is applicable to any cell within the positioning effective area. Regardless of the coverage area of ​​the cell to which the terminal device moves, the same configuration is used to send the positioning SRS, including but not limited to the following content:

[0326] For power control, the terminal device uses common power control parameters such as P0, alpha and PL-RS.

[0327] For the spatial filter, the terminal device uses a fixed wide spatial filter (also called a wide beam) or determines the spatial filter in a scanning manner.

[0328] For time-frequency resources, the terminal device uses the same sequence ID and / or cyclic shift for transmission.

[0329] For example, referring to the description of "Positioning SRS Resource Set and Positioning Resource Configuration" above, the network device can configure the Positioning SRS IE on a BWP of the serving cell of the terminal device. This simplifies the RRC configuration and the burden of storing configuration information on the terminal device.

[0330] It should be noted that when the pre-configuration information includes the common positioning SRS configuration information of the multiple cells, even if the terminal device obtains the first information, the positioning SRS configuration information used by the terminal device may not be switched, or the terminal device may switch the positioning SRS configuration information used by the terminal device through other means. This application does not make specific limitations on this.

[0331] In some embodiments, the pre-configuration information includes at least one of the following: positioning SRS configuration information specific to some of the multiple cells, and positioning SRS configuration information common to the some of the cells.

[0332] Exemplarily, the relationship between some of the multiple cells and some of the positioning SRS configuration information in the multiple positioning SRS configuration information is a many-to-one relationship, and the relationship between another part of the multiple cells and another part of the positioning SRS configuration information in the multiple positioning SRS configuration information is a many-to-one relationship.

[0333] In some embodiments, the pre-configuration information includes at least one of the following: partial configuration information common to the multiple cells, and configuration information specific to each of the multiple cells.

[0334] Exemplarily, certain parameters configured by the network device for positioning SRS may be public configuration parameters within the effective positioning area, such as the sequence ID of the positioning SRS, the resources occupied by the positioning SRS in the time domain and the frequency domain, etc.; at the same time, exclusive parameters for the positioning SRS are also configured, which can be understood as being cell-exclusive or even spatial filter-exclusive; for example, the power control parameters of the positioning SRS (such as P0, alpha and PL RS) can be independently configured according to each positioning SRS resource set; for spatial relationship information (i.e., spatial relation information), it can be independently configured according to each positioning SRS resource.

[0335] In some embodiments, the number of the multiple cells is less than or equal to the maximum number of cells supported by the terminal device when performing downlink measurements within the positioning validity area; or, the number of the multiple cells is less than or equal to the maximum number of cells supported by the terminal device when performing downlink measurements within at least one time unit and within the positioning validity area.

[0336] Exemplarily, the number of the multiple cells is less than or equal to the maximum number of cells supported by the terminal device when the terminal device performs downlink measurement at the same time and within the positioning validity area; or, the number of the multiple cells is less than or equal to the maximum number of cells supported by the terminal device when the terminal device performs downlink measurement within at least one time unit and within the positioning validity area.

[0337] Exemplarily, the time units in the at least one time unit include but are not limited to: symbols, time slots, subframes, frames and other time units specified in the communication protocol.

[0338] In some embodiments, the method 200 may further include:

[0339] Send the downlink measurement capability of the terminal device.

[0340] Exemplarily, before receiving the pre-configuration information sent by the network device, the terminal device may first send the downlink measurement capability of the terminal device to the network device, so that the network device can configure multiple positioning SRS configuration information for the terminal device based on the downlink measurement capability of the terminal device.
