[0002] In the New Radio (NR) system, according to the basic principles of positioning, it can be known that if the bandwidth of the signal used for positioning is increased, the positioning accuracy can be improved in theory. On the one hand, the maximum bandwidth of an NR carrier is limited. For example, in Frequency Range 1, the maximum bandwidth of an NR carrier is 100MHz. On the other hand, the operator's spectrum is limited, and the spectrum of a single carrier may not reach the maximum bandwidth supported by the protocol. Positioning signals on different carriers can be measured independently.

[0024] The following describes the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0025] The following is a brief description of the relevant background of the present invention, as follows:

[0026] Positioning technology is one of the core technologies of modern communication and navigation systems. For example, satellite navigation systems, Bluetooth, and Wireless Fidelity (WiFi) all provide positioning functions. Similarly, modern cellular communication systems also support positioning functions. Starting from the 3G and 4G Long Term Evolution (LTE) communication systems, various advanced positioning technologies have gradually been added to cellular communication systems. In the 5G New Radio (NR) communication system, positioning technology will also be supported, and the specific standards were introduced in Release 16. In the New Radio (NR) version of 3GPP Release 16 (R16), the following positioning technologies were introduced:

[0027] 1) Downlink-Time Difference of Arrival (DL-TDOA)

[0028] 2) Uplink-Time Difference of Arrival (UL-TDOA)

[0029] 3) Multiple Round Trip Time (Multi-RTT)

[0030] 4) Downlink-Angle of Departure (DL-AoD)

[0031] 5) Uplink-Angle of Departure (UL-AoA)

[0032] 6) Enhanced Cell ID Positioning

[0033] In order to support various positioning methods, R16 NR introduced a positioning reference signal (PRS) in the downlink and a sounding reference signal (SRS for positioning) in the uplink.

[0034] The NR-based positioning function mainly involves three parts:

[0035] 1) User Equipment (UE)

[0036] 2) Multiple network transmission / reception points (TRP)

[0037] Multiple TRPs around the terminal participate in cellular positioning;

[0038] A base station may be a TRP;

[0039] There may be multiple TRPs under one base station.

[0040] 3) Location Server

[0041] The work of the positioning server includes positioning processes, etc. For example, the positioning server may include a location management function (LMF).

[0042] 1. Downlink-based positioning methods can be divided into two categories

[0043] 1) UE-assisted positioning method

[0044] i. UE is responsible for positioning related measurements;

[0045] ii. The network calculates the location information based on the measurement results reported by the UE.

[0046] 2) UE-based positioning method

[0047] i. The UE performs positioning-related measurements and calculates location information based on the measurement results.

[0048] 2. The following takes a downlink-based positioning method (UE-assisted positioning method) as an example to illustrate the basic process ( Figure 1-1 ):

[0049] 1) The positioning server notifies the TRP of the relevant configuration;

[0050] It may include PRS configuration information and / or the type of measurement results that the terminal needs to report.

[0051] 2) TRP sends a positioning signal PRS.

[0052] 3) The terminal receives the positioning signal PRS and performs measurement;

[0053] Depending on the positioning method, the measurement results required by the terminal are also different.

[0054] 4) The terminal feeds back the measurement results to the positioning server;

[0055] The terminal feeds back the measurement results to the positioning server through the base station.

[0056] 5) The positioning server calculates the location-related information.

[0057] The above is a schematic diagram of the UE-assisted positioning process. In the UE-based positioning method, in step 4, the terminal directly calculates location-related information based on the measurement results, without reporting the measurement results to the positioning server, which then performs the calculation. In the UE-based positioning method, the terminal needs to know the location information corresponding to the TRP, so the network needs to notify the UE of the TRP's location information in advance.

[0058] 3. The following takes a positioning method based on uplink as an example to illustrate the basic process ( Figure 1-2 ):

[0059] 1) The positioning server notifies the TRP of the relevant configuration;

[0060] 2) The base station sends relevant signaling to the terminal;

[0061] 3) The terminal sends an uplink signal (SRS for positioning);

[0062] 4) TRP measures the SRS for positioning and sends the measurement results to the positioning server;

[0063] 5) The positioning server calculates the location-related information.

[0064] According to the basic principles of positioning, if the bandwidth of the signal used for positioning is increased, the positioning accuracy can be theoretically improved. On the one hand, the maximum bandwidth of an NR carrier is limited. For example, in frequency range 1 (Frequency Range 1), the maximum bandwidth of an NR carrier is 100 MHz. On the other hand, the operator's spectrum is limited, and the spectrum of a single carrier may not reach the maximum bandwidth supported by the protocol. Positioning signals on different carriers can be measured independently. In order to further improve positioning accuracy, one method is to use multiple positioning signals together to support the positioning function. Optionally, multiple positioning signals can be on different frequency resources or on different carriers. The joint use method can include various implementations, such as what can be called an aggregation processing method, or the positioning signals on different carriers are combined and regarded as an "equivalent" signal with a larger bandwidth, that is, the signals are aggregated (aggregation of signals) and measured as an "aggregated signal". According to different specific implementations of the joint use of multiple positioning signals, it can correspond to the aggregation of NR positioning frequency layers, or the aggregation of downlink positioning signals (Aggregation of DL PRS), or the aggregation of downlink positioning signal resources (Aggregation of DL PRSresources), or the aggregation of downlink positioning signals (Aggregation of DL PRS), or the aggregation of downlink positioning signals in one or more positioning frequency layers (Aggregation of DL PRS in one or more positioning frequency layers). Aggregation can also be expressed by other similar words, such as bundling, bundling in frequency domain, and joint reception, which are not listed here. In the embodiment of the present application, the name and implementation scheme of the method for the joint use of multiple positioning signals are not specifically limited.

[0065] Taking the aggregation of two downlink positioning signals as an example, the terminal needs to directly receive the two signals at a higher sampling rate. This is equivalent to receiving the two signals as one equivalent signal occupying a larger frequency domain resource. It cannot be simply divided into two signal paths, each receiving one downlink positioning signal.

[0066] This method places high demands on time synchronization errors and phase continuity between the two carriers. It also places high latency requirements on both the signal transmitter and the signal measurement party. Depending on the specific frequency band and bandwidth, the terminal may need to use a higher sampling rate to implement the aggregation processing method. Because the aggregation processing method places high demands on product implementation, a reasonable terminal capability (UE capacity) reporting mechanism needs to be designed. While ensuring maximum support for the aggregation processing method within the constraints of terminal capabilities, it also needs to avoid excessively high terminal capability requirements that would render it unfeasible for commercial terminals. Currently, no design solutions addressing these UE capabilities have been identified.

[0067] In the present invention, for the convenience of description, positioning signal and positioning signal resource are often used interchangeably without making additional distinction. For example, when using positioning signal, it can also refer to positioning signal resource.

[0068] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as: 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, Advanced Long Term Evolution (LTE-A) system, New Radio (NR) system, NR system evolution system, LTE on unlicensed spectrum (LTE-U) system, NR on unlicensed spectrum (NR-U) system, Non-Terrestrial Networks (NTN) system, Universal Mobile Telecommunication System (UMTS), Wireless Local Area Networks (WLAN), Wireless Fidelity (Wireless Fidelity) system. Fidelity, WiFi), fifth-generation communication (5th-Generation, 5G) system or other communication systems, etc.

[0069] Generally speaking, traditional communication systems support a limited number of connections and are easy to implement. However, with the development of communication technology, mobile communication systems will not only support traditional communications, but will also support, for example, device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC), vehicle-to-vehicle (V2V) communication, or vehicle-to-everything (V2X) communication, etc. The embodiments of the present application can also be applied to these communication systems.

[0076] As an example and not a limitation, in the embodiment of the present application, the terminal device may also be a wearable device. Wearable devices may also be called wearable smart devices, which are a general term for wearable devices that are intelligently designed and developed using wearable technology for daily wear, such as glasses, gloves, watches, clothing, and shoes. A wearable device is a portable device that is worn directly on the body or integrated into the user's clothes or accessories. Wearable devices are not only hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include those that are fully functional, large in size, and can achieve complete or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0077] In an embodiment of the present application, the network device may be a device for communicating with a mobile device. The network device may be an access point (AP) in WLAN, a base station (BTS) in GSM or CDMA, a base station (NodeB, NB) in WCDMA, an evolved base station (eNB or eNodeB) in LTE, or a relay station or access point, or a vehicle-mounted device, a wearable device, and a network device (gNB) in an NR network, or a network device in a future evolved PLMN network or a network device in an NTN network, etc.

[0078] As an example and not a limitation, in an embodiment of the present application, the network device may have a mobile feature, for example, the network device may be a mobile device. Alternatively, the network device may be a satellite or a balloon station. For example, the satellite may be a low earth orbit (LEO) satellite, a medium earth orbit (MEO) satellite, a geostationary earth orbit (GEO) satellite, a high elliptical orbit (HEO) satellite, etc. Optionally, the network device may also be a base station set up in a location such as land or water.

[0079] In an embodiment of the present application, the network device can provide services for a cell, and the terminal device communicates with the network device through the transmission resources used by the cell (for example, frequency domain resources, or spectrum resources). The cell can be a cell corresponding to the network device (for example, a base station). The cell can belong to a macro base station or a base station corresponding to a small cell. The small cells here may include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0080] like Figure 2 FIG2 shows a system architecture diagram of a communication system used in an embodiment of the present invention. The communication system may include network devices, which may be devices that communicate with terminal devices (also referred to as communication terminals or terminals). The network devices may provide communication coverage for a specific geographic area and may communicate with terminal devices within the coverage area. The network devices may also be devices such as servers (e.g., positioning servers). Figure 2The exemplary embodiment shows one network device and two terminal devices. Optionally, the communication system may include multiple network devices, and each network device may include another number of terminal devices within its coverage area, which is not limited in this embodiment of the present application. Optionally, the communication system may also include other network entities such as a network controller and a mobility management entity, which is not limited in this embodiment of the present application.

[0081] Among them, the network equipment may include access network equipment and core network equipment. That is, the wireless communication system also includes multiple core networks for communicating with the access network equipment. The access network equipment can be an evolutionary base station (evolutional node B, abbreviated as eNB or e-NodeB) macro base station, micro base station (also called "small base station"), pico base station, access point (AP), transmission point (TP) or new generation Node B (gNodeB), etc. in a long-term evolution (LTE) system, a next-generation (mobile communication system) (nextradio, NR) system or an authorized auxiliary access long-term evolution (LAA-LTE) system.

[0082] It should be understood that the device with communication function in the network / system in the embodiment of the present application can be called a communication device. Figure 2 Taking the communication system shown as an example, the communication equipment may include network equipment and terminal equipment with communication functions. The network equipment and terminal equipment may be the specific equipment described in the embodiments of the present invention, which will not be repeated here; the communication equipment may also include other equipment in the communication system, such as network controllers, mobile management entities and other network entities, which are not limited in the embodiments of the present application.

[0083] The technical solution of the present invention is further described below by way of examples. Figure 3 FIG. 1 is a schematic diagram of an embodiment of a method for reporting positioning capabilities according to an embodiment of the present invention, which may include:

[0084] 301. A terminal device reports to a network device via a first signaling that it supports a first terminal capability, where the first terminal capability is a positioning function used in conjunction with a downlink positioning signal. Optionally, the network device receives the support for the first terminal capability reported by the terminal device via the first signaling.

[0085] 1. The terminal device reports to the network device through a first signaling that it supports a first terminal capability (UE capability). The first terminal capability is a positioning function based on the joint use of downlink (DL) positioning signals. It can be understood that the first terminal capability is a new capability that allows the UE to support a larger "equivalent bandwidth" of positioning signals. A larger "equivalent bandwidth" can improve positioning accuracy. By introducing new capabilities, high-capability terminal devices can provide better positioning performance.

[0086] 1.1. Optionally, the first signaling is UE capacity signaling. It is understandable that the UE capacity signaling may include Long Term Evolution Positioning Protocol (LTE Positioning Protocol, LPP) signaling, Radio Resource Control (RRC) signaling, and the like.

[0087] 1.2. Optionally, the first signaling may include LPP signaling. That is, the first signaling is transmitted via the Long Term Evolution Positioning Protocol (LTE Positioning Protocol, LPP). In this implementation, the existing protocol process can be reused, and the standardization workload is small.

[0088] Optionally, the downlink positioning signal may include a downlink positioning reference signal (PRS), a synchronization signal block (SS / PBCH block), a channel state information reference signal (CSI-RS), etc. For simplicity in the subsequent description, PRS is sometimes used to refer to the downlink positioning signal.

[0089] Optionally, the network device is a positioning server (Location server).

[0090] Optionally, 1) the first signaling is carried in the new radio downlink positioning reference signal resource capability NR-DL-PRS-ResourcesCapability, or,

[0091] 2) The first signaling is carried in the resource capability of each frequency band in the downlink positioning reference signal DL-PRS-ResourcesCapabilityPerBand, or,

[0092] 3) The first signaling is carried in the new radio downlink arrival time difference positioning method capability NR-DL-TDOA-ProvideCapabilities, or,

[0093] 4) The first signaling is carried in the new radio downlink arrival time difference positioning method measurement capability NR-DL-TDOA-MeasurementCapability, or,

[0094] 5) The first signaling is carried in the new radio downlink departure angle positioning method providing capabilities NR-DL-AoD-ProvideCapabilities, or,

[0095] 6) The first signaling is carried in the new radio downlink departure angle positioning method measurement capability NR-DL-AoD-MeasurementCapability, or,

[0096] 7) The first signaling is carried in the new wireless multiple round-trip time positioning method providing capabilities NR-Multi-RTT-ProvideCapabilities, or,

[0097] 8) The first signaling carries the new wireless multiple round-trip time positioning method measurement capability NR-Multi-RTT-MeasurementCapability.

[0098] Exemplarily, the first signaling is transmitted via NR-DL-PRS-ResourcesCapability (an existing NR Positioning Information Element). Unless otherwise specified, the existing NR positioning information element names mentioned in this document refer to the NR positioning information element names mentioned in TS 37.355: LTE Positioning Protocol (LPP) (Release 16). It should be noted that the names of these NR positioning information elements can remain unchanged, but their specific contents need to be added or modified accordingly for the new information mentioned in this application.

[0099] 1.3. Optionally, the first signaling may include RRC signaling. In this implementation, a new signaling method is introduced for reporting positioning capabilities, which can reduce the reporting delay of the positioning capabilities supported by the terminal device.

[0100] Optionally, the network device is a serving network device of the terminal device. Optionally, the serving network device may be a serving access network device, such as a serving base station (gNB).

[0101] Optionally, 1) the first signaling is carried in the new radio downlink positioning reference signal resource capability NR-DL-PRS-ResourcesCapability, or,

[0102] 2) The first signaling is carried in the resource capability of each frequency band in the downlink positioning reference signal DL-PRS-ResourcesCapabilityPerBand, or,

[0103] 3) The first signaling is carried in the new radio downlink arrival time difference positioning method capability NR-DL-TDOA-ProvideCapabilities, or,

[0104] 4) The first signaling is carried in the new radio downlink arrival time difference positioning method measurement capability NR-DL-TDOA-MeasurementCapability, or,

[0105] 5) The first signaling is carried in the new radio downlink departure angle positioning method providing capabilities NR-DL-AoD-ProvideCapabilities, or,

[0106] 6) The first signaling is carried in the new radio downlink departure angle positioning method measurement capability NR-DL-AoD-MeasurementCapability, or,

[0107] 7) The first signaling is carried in the new wireless multiple round-trip time positioning method providing capabilities NR-Multi-RTT-ProvideCapabilities, or,

[0108] 8) The first signaling carries the new wireless multiple round-trip time positioning method measurement capability NR-Multi-RTT-MeasurementCapability.

[0109] 2. Optionally, the first terminal capability indicates a maximum number of corresponding joint layers used jointly by multiple downlink positioning signals.

[0110] Optionally, the joint layer includes a positioning frequency layer or an aggregation layer. That is, the first signaling can be used to indicate the maximum number of positioning frequency layers corresponding to the first terminal capability, or the maximum number of aggregation layers of downlink positioning signals that can be supported by downlink positioning. Positioning frequency layers (PFL) or aggregation layers are used here to describe the capabilities corresponding to the maximum number of layers, and other concepts may also be used to describe them. They are not listed one by one and are all within the scope of protection of the present invention. Optionally, positioning frequency layers (Positioning Frequency Layers) can also be called positioning layers (positioning layer).

[0111] That is, the first signaling is also used to indicate the maximum number M of positioning frequency layers (PFL) corresponding to the first terminal capability (i.e., the number of positioning frequency layers), or the maximum number N of aggregation layers for signal aggregation. It is understandable that the terminal device can report the maximum capability to the network device, and the network device configuration can be less than or equal to the maximum capability.

[0112] Optionally, the above-mentioned aggregation layer does not necessarily need to be explicitly defined. It can be a descriptive term introduced merely to facilitate the description of signal aggregation capabilities. For example, if two signals on different frequency domain resources can be aggregated and processed, it is considered that the aggregation layer corresponding to such aggregation processing is 2; if three signals on different frequency domain resources can be aggregated and processed, it is considered that the aggregation layer corresponding to such aggregation processing is 3.

[0113] It should be noted that the reporting of specific positioning frequency layers or aggregation of signals on several aggregation layers can provide greater flexibility for terminal device implementation. For example, high-capability terminal devices can support aggregation of more positioning frequency layers, while low-capability terminal devices can support aggregation of fewer positioning frequency layers.

[0114] 2.1. Optionally, different joint layers occupy different frequency domain resources.

[0115] Exemplarily, downlink positioning signals corresponding to different positioning frequency layers are on different frequency domain resources, or downlink positioning signals corresponding to different aggregation layers are on different frequency domain resources.

[0116] 2.2. Optionally, the same joint layers may have the same values ​​for some or all of the following configuration parameters, which may include but are not limited to the following:

[0117] Subcarrier spacing, cyclic prefix, starting physical resource block (PRB), comb size, signal bandwidth or resource bandwidth, and frequency of the reference resource block.

[0118] 2.3. Optionally, the maximum number of the combined layers is 2, 3 or 4.

[0119] It is understandable that the terminal device can report to the network device the maximum number of positioning frequency layers corresponding to the first terminal capability, or the maximum number of aggregation layers of signal aggregation that can be supported by the first terminal capability.

[0120] Optionally, the network device receives the maximum number of positioning frequency layers corresponding to the first terminal capability reported by the terminal device, or the maximum number of aggregation layers for signal aggregation supported by the first terminal capability. That is, the terminal device can directly report the maximum number of positioning frequency layers M corresponding to the first terminal capability, or the maximum number of aggregation layers N for signal aggregation supported by the first terminal capability. This can provide greater flexibility, allowing each terminal device to indicate more detailed capabilities.

[0121] (1) Optionally, the maximum number of layers of the joint layer indicated by the first field is 2, 3 or 4.

[0122] For example, Capability 1 supported

[0123] maxLyaer one of{2,3,4}

[0124] It can be understood that the maximum number of positioning frequency layers M is 2, 3 or 4, or the maximum number of aggregation layers N is 2, 3 or 4.

[0125] (2) Optionally, the maximum number of layers of the joint layer is indicated by a second field, and the value of the maximum number of layers of the joint layer indicated by the second field under default conditions is 2, and the value of the maximum number of layers of the joint layer indicated by the second field under non-default conditions is 3 or 4.

[0126] For example, Capability 1 supported

[0127] maxLyaer one of{3,4}(notreported,default value=2)

[0128] It can be understood that the terminal device indicates the maximum number of positioning frequency layers corresponding to the first terminal capability or the maximum number of aggregation layers of signal aggregation that the first terminal capability can support through the second domain. When the second domain is in the default (also called default) state, the maximum number of positioning frequency layers or the maximum number of aggregation layers indicated by the second domain is 2. When the second domain is in a non-default state, the value indicated by the second domain is 3 or 4, which means that the maximum number of positioning frequency layers or the maximum number of aggregation layers is 3 or 4.

[0129] Compared with scheme (1), scheme (2) can use fewer bits to indicate the maximum number of joint layers. For example, the first field of scheme (1) requires at least 2 bits, and the second field of scheme (2) requires at least 1 bit.

[0130] (3) Optionally, when the terminal device reports support for the first terminal capability, and the first terminal capability does not indicate the maximum number of joint layers corresponding to the joint use of multiple downlink positioning signals, the maximum number of joint layers defaults to 2.

[0131] For example, Capability 1 supported (default 2, no layer number reporting required)

[0132] In this implementation, the fixed support of the first terminal capability corresponds to two positioning frequency layers or aggregation layers, which can reduce the reporting signaling overhead compared with the solution of reporting the maximum number of positioning frequency layers or the maximum number of aggregation layers.

[0133] 2.4. The maximum number of layers of the joint layer corresponding to the first terminal capability is configured separately from the value of the third terminal capability. The value of the third terminal capability is reported by the terminal device through the maximum number of positioning layers maxNrOfPosLayer-r16.

[0134] That is, it can be understood that the maximum number of positioning frequency layers M corresponding to the first terminal capability, or the maximum number of aggregation layers N of signal aggregation that the first terminal capability can support, and the value of the third terminal capability are configured separately, and the third terminal capability is used to indicate the maximum number of positioning frequency layers supported by the terminal device. In this implementation, the first terminal capability and the third terminal capability are configured separately, which can provide greater flexibility for terminal device implementation, so that more corresponding terminal devices can be designed for typical applications.

[0135] The relevant protocols of maxNrOfPosLayer-r16 are as follows:

[0136] maxNrOfPosLayer

[0137] Indicates the maximum number of supported positioning layer.

[0138] Optionally, the maximum number of layers of the joint layer corresponding to the first terminal capability is less than or equal to the value of the third terminal capability.

[0139] That is, it can be understood that the maximum number of positioning frequency layers M corresponding to the first terminal capability, or the maximum number of aggregation layers N of signal aggregation that can be supported by the first terminal capability, is less than or equal to the value of the third terminal capability, that is, less than or equal to the maxNrOfPosLayer-r16 value reported by the terminal device. In this implementation, the values ​​of the two configurations are restricted to avoid poor terminal device implementation. For example, the aggregation processing method can support more positioning frequency layers, while ordinary processing can only support lower positioning frequency layers or aggregation layers.

[0140] Optionally, the value of maxNrOfPosLayer-r16 can be 1, 2, 3, or 4.

[0141] Optionally, when the value of maxNrOfPosLayer-r16 is 1, the terminal device does not support the first terminal capability; optionally, the terminal device may not report to the network device that it does not support the first terminal capability.

[0142] Optionally, when the value of maxNrOfPosLayer-r16 is 2, 3, or 4, the terminal device supports the first terminal capability.

[0143] Optionally, the existing terminal capability maxNrOfPosLayer-r16 indication can support receiving downlink positioning signals on multiple positioning frequency layers, but does not need to be processed in an aggregated manner. That is, the terminal device can measure each downlink positioning signal separately in the existing manner, and then process it according to certain rules and then choose to report it. That is, the measurement results of the downlink positioning signals on different frequency layers and the downlink positioning signals on the same frequency layer can be processed similarly.

[0144]

[0145]

[0146] 2.5. Optionally, the maximum value of the aggregate bandwidths on the multiple joint layers corresponding to the first terminal capability is determined according to a preset protocol; or, the maximum value of the joint bandwidths on the multiple joint layers corresponding to the first terminal capability is set to a default value;

[0147] It can be understood that the maximum bandwidth of the downlink positioning signal on multiple positioning frequency layers or multiple aggregation layers can be specified in accordance with the existing protocol (TS 37.355 (Rel-16)). That is, the preset protocol can be understood as the existing protocol (TS 37.355 (Rel-16)). In this implementation method, the maximum possible signal bandwidth is supported directly according to the maximum number of layers M of the aggregated positioning frequency layer, or the multiples of the maximum number of layers N of the aggregation layer. For example, if the maximum signal bandwidth on a positioning frequency layer that the terminal device can support according to the existing protocol is maxBW, then the maximum signal aggregation bandwidth that can be supported for aggregation processing is M*maxBW, or N*maxBW, where the maximum signal aggregation bandwidth can be determined according to the subsequent specific calculation method of the equivalent total bandwidth. This can save signaling overhead, and at the same time, enable the transmitter to retain the existing processing method of each positioning frequency layer as much as possible, reduce additional restrictions, and reduce implementation complexity.

[0148] The pre-configured protocol TS 37.355 (Rel-16) is as follows:

[0149]

[0150] Existing UE capability signaling configuration:

[0151] supportedBandwidthPRS (supported PRS bandwidth)

[0152] Indicates the maximum number of DL-PRS bandwidth in MHz, which is supported and reported by UE.

[0153] The corresponding solution is: if the terminal device reports the supported bandwidth (for example, FR1, which is the medium and low frequency band) as BW according to the R16 protocol, then if the terminal supports aggregation and the maximum number of supported aggregation layers is N, the maximum aggregation bandwidth is BW*N.

[0154] 3. Optionally, the first signaling further indicates first frequency band information, where the first frequency band information indicates a frequency band occupied by the terminal device supporting the first terminal capability.

[0155] In this implementation, the frequency band information corresponding to the first signaling indication can avoid the need for the terminal device to support this capability on all frequency bands that support positioning if it supports this capability, thereby providing greater freedom for the terminal device implementation and allowing more terminal devices to support the feature (which may only be supported on some frequency bands).

[0156] 3.1. Optionally, the first frequency band information includes one or more frequency band information.

[0157] This implementation reduces signaling overhead for signal aggregation within an intra-band positioning frequency layer or aggregation layer. It also reduces terminal device implementation complexity, as only signal aggregation within the intra-band positioning frequency layer or aggregation layer needs to be supported.

[0158] Optionally, one or more frequency band information is implemented through a list structure or a sequence structure, that is, one or more frequency band information is implemented through a list structure of frequency band information or a SEQUENCE structure of frequency band information.

[0159] Optionally, when the first frequency band information includes one or more frequency band information, the one or more frequency band information is transmitted through NR-DL-PRS-ResourcesCapability or DL-PRS-ResourcesCapabilityPerBand.

[0160] (1) Frequency band information is transmitted through the positioning information element NR-DL-PRS-ResourcesCapability.

[0161] The following is an example of transmitting frequency band information using the positioning information element NR-DL-PRS-ResourcesCapability. This example modifies an existing information element, with the modified parts in bold (similar to the following and not further explained). The specific names used are for illustrative purposes only and may be other names (similar to the following and not further explained).

[0162] For example, see Example 3-1, as shown below:

[0163]

[0164] Among them, the Chinese translation of AggregationCapableBandList is: frequency band aggregation capability list;

[0165] The Chinese translation of bandInfomation is: frequency band information.

[0166] Optional. The bolded new part is an optional option.

[0167] Optionally, the representation of "bandInfomation" above can have different options, which may be one of the following:

[0168] i: The value of bandInfomation is A, corresponding to the frequency band corresponding to the Ath (or A+1th)th element in the Sequence structure in the dl-PRS-ResourcesCapabilityBandList (underlined portion) above. In this implementation, because the frequency bands supported by terminal devices are generally smaller than the maximum range, signaling reporting overhead can be reduced.

[0169] ii: The value A of bandInfomation corresponds to the NR band indicator, which is an integer greater than or equal to 1 and less than or equal to 1024. In this implementation, the signaling field size is fixed, avoiding dynamic changes in the number of bits in this field and reducing processing complexity.

[0170] Optionally, the NR band indicator corresponding to bandInfomation is also indicated in an element of dl-PRS-ResourcesCapabilityBandList

[0171] Optionally, the "AggregationCapableBandList" may be the first signaling itself, and the "AggregationCapableBandList" is used to indicate that the first terminal device supports the first terminal capability. In this implementation, signaling reporting overhead can be reduced.

[0172] (2) Frequency band information is transmitted through the positioning information element DL-PRS-ResourcesCapabilityPerBand.

[0173] The following is an example of transmitting frequency band information through the positioning information element DL-PRS-ResourcesCapabilityPerBand.

[0174] For example, see Example 3-2, as shown below:

[0175]

[0176] Among them, the Chinese translation of AggregationCapability is: aggregation capability.

[0177] Optional. The bold new part is an optional option.

[0178] Optionally, the specific implementation of the above "AggregationCapability" and type "Type" can have the following options:

[0179] 1) Type can have two optional values: a1 and a2. When different values ​​are configured, aggregation capability is not supported or supported, respectively.

[0180] 2) If "AggregationCapability" is not configured, the first terminal device does not support the first terminal capability; if "AggregationCapability" is configured (for example, the Type value is configured as supported), the first terminal device supports the first terminal capability. In this implementation, the signaling reporting overhead can be reduced.

[0181] Optionally, the "AggregationCapability" may be the first signaling itself, and the "AggregationCapability" is used to indicate that the first terminal device supports the first terminal capability. In this implementation, signaling reporting overhead can be reduced.

[0182] In the above example, the type corresponding to the new domain can be simply represented by "Type" or "type". Similar processing will be used in subsequent embodiments and will not be explained one by one.

[0183] 3.2. Optionally, the first frequency band information includes one or more frequency band combination information.

[0184] In this implementation mode, more frequency band combinations can be supported, which is convenient for supporting various complex available frequency band situations of operators.

[0185] Optionally, one or more frequency band combination information is implemented through a list structure or a SEQUENCE structure, that is, one or more frequency band information is implemented through a list structure of frequency band combination information or a SEQUENCE structure of frequency band combination information.

[0186] Optionally, when the first frequency band information includes one or more frequency band combination information, the one or more frequency band combination information is transmitted through NR-DL-PRS-ResourcesCapability. That is, the frequency band combination information is transmitted through the positioning information element NR-DL-PRS-ResourcesCapability.

[0187] The following is an example of transmitting frequency band combination information using the positioning information element NR-DL-PRS-ResourcesCapability. This example modifies an existing information element, with the modified parts in bold (subsequent examples are similar and will not be further explained). The specific names used are for illustrative purposes only and may be replaced by other names.

[0188] For example, see Example 3-3, as shown below:

[0189]

[0190] Among them, the Chinese translation of AggregationCapableBandCombinationList is: frequency band combination aggregation capability list;

[0191] The Chinese translation of bandCombinationInfomation is: frequency band combination information.

[0192] Optional. The bold new part is an optional option.

[0193] Optionally, the representation method of the above "bandCombinationInfomation" can have different options (possibly one of the following), taking two frequency bands as an example, and can be extended to more frequency bands.

[0194] 1) bandCombinationInfomation indicates two values, A1 and A2, corresponding to the frequency bands corresponding to the A1 (or A1+1) and A2 (or A2+1) elements in the Sequence structure in the dl-PRS-ResourcesCapabilityBandList (underlined portion) above. In this implementation, because the frequency bands supported by terminal devices are generally smaller than the maximum range, signaling reporting overhead can be reduced.

[0195] 2) bandCombinationInfomation indicates two values, A1 and A2, each of which corresponds to an NR band indicator (NR band indicator), which is an integer greater than or equal to 1 and less than or equal to 1024. In this implementation, the signaling field size is fixed, avoiding dynamic changes in the number of bits in this field and reducing processing complexity.

[0196] Optionally, the NR band indicator (NR band indicator) corresponding to bandCombinationInfomation is also indicated in an element of dl-PRS-ResourcesCapabilityBandList.

[0197] Optionally, the "AggregationCapableBandCombinationList" may be the first signaling itself, and the "AggregationCapableBandCombinationList" is used to indicate that the first terminal device supports the first terminal capability. In this implementation, signaling reporting overhead can be reduced.

[0198] 4. Optionally, the terminal device indicates to the network device the maximum value of the joint bandwidth on the multiple joint layers corresponding to the first terminal capability through the first signaling or signaling other than the first signaling.

[0199] Exemplarily, when the maximum value of the joint bandwidth is indicated through the first signaling, optional implementation methods may include: one is to have a general field in the first signaling to indicate the maximum value of the joint bandwidth of each joint layer; the other is to indicate the maximum value of the aggregate bandwidth of each joint layer in the configuration information of each joint layer in the first signaling.

[0200] The maximum value of the joint bandwidths on the multiple joint layers corresponding to the first terminal capability may also be referred to as the maximum aggregate bandwidth on the multiple joint layers corresponding to the first terminal capability.

[0201] Optionally, the maximum aggregate bandwidth on the multiple joint layers corresponding to the first terminal capability may be configured separately in each frequency band.

[0202] In this implementation, the introduction of maximum aggregate bandwidth capability can provide greater flexibility for UE implementation, that is, terminal devices of different capability levels can report different maximum aggregate bandwidth capabilities, which can provide more diverse terminal devices suitable for various application scenarios and services.

[0203] 4.1. Optionally, when the terminal device supports aggregation of multiple downlink positioning signals, the maximum value of the joint bandwidth corresponds to the maximum equivalent total bandwidth of the multiple downlink positioning signals.

[0204] Optionally, the equivalent total bandwidth is the first equivalent total bandwidth or the second equivalent total bandwidth.

[0205] (1) The first equivalent total bandwidth is the sum of the downlink positioning signal bandwidths on different joint layers.

[0206] It can be understood that the first equivalent total bandwidth is the sum of the bandwidths of the uplink and downlink positioning signals of different positioning frequency layers or different aggregation layers. That is, the equivalent total bandwidth of multiple downlink positioning signals is the sum of the bandwidths of the uplink and downlink positioning signals of different positioning frequency layers, or different aggregation layers (which can be recorded as the first equivalent total bandwidth mode. In the subsequent description, the first equivalent total bandwidth mode and the first equivalent total bandwidth are not distinguished and are used in combination). In this implementation method, only the actual bandwidth of the positioning signal is considered, which can further improve the requirements for the terminal device and further provide the positioning accuracy requirements.

[0207] For example, see Examples 3-4. Figure 4A The figure is a schematic diagram of the equivalent total bandwidth after the uplink and downlink positioning signals of two positioning frequency layers are aggregated in an embodiment of the present invention.

[0208] Taking two positioning frequency layers or aggregation layers as an example, it can be expanded to more positioning frequency layers or aggregation layers. Assume that the downlink positioning signal bandwidth on positioning frequency layer 0 is X (the unit can adopt various units corresponding to the frequency domain, such as RB, or Hertz, or Megahertz Mhz, without limitation. When it comes to the units of bandwidth or other frequency domain resources in the future, they all have similar meanings and no additional explanation is needed), and the downlink positioning signal bandwidth on positioning frequency layer 1 is Y. Then the equivalent total bandwidth after the aggregation of the downlink positioning signals on the two positioning frequency layers is X+Y.

[0209] (2) The second equivalent total bandwidth is the bandwidth between the lowest frequency position and the highest frequency position occupied by the downlink positioning signals on different joint layers.

[0210] It can be understood that the second equivalent total bandwidth is the bandwidth between the lowest frequency position and the highest frequency position occupied by the uplink and downlink positioning signals of different positioning frequency layers or different aggregation layers. That is, the equivalent total bandwidth of multiple downlink positioning signals is the bandwidth between the lowest frequency position and the highest frequency position occupied by the uplink and downlink positioning signals of different positioning frequency layers, or different aggregation layers. (If there is a gap in the frequency of the uplink and downlink positioning signals of different positioning frequency layers or different aggregation layers, the gap is also calculated in this bandwidth) (can be recorded as the second mode of equivalent total bandwidth. In the subsequent description, the second mode of equivalent total bandwidth and the second equivalent total bandwidth are not distinguished and are used in combination). In this implementation method, considering all bandwidths spanned by the aggregated signal can be closer to the actual hardware implementation, reduce the processing requirements for the terminal device, and provide greater flexibility for the terminal device implementation, so that more terminal devices can support this feature.

[0211] For example, see Examples 3-5. Figure 4B FIG2 is another schematic diagram of the equivalent total bandwidth after the uplink and downlink positioning signals of two positioning frequency layers are aggregated in an embodiment of the present invention. As shown below:

[0212] Taking two positioning frequency layers as an example, this can be expanded to include more positioning frequency layers. Assuming the downlink positioning signal bandwidth on positioning frequency layer 0 is X, the downlink positioning signal bandwidth on positioning frequency layer 1 is Y, and the bandwidth between the downlink positioning signal on positioning frequency layer 0 and the downlink positioning signal on positioning frequency layer 1 is Z, then the equivalent total bandwidth after aggregating the uplink and downlink positioning signals on the two positioning frequency layers is X+Y+Z.

[0213] (3) Optionally, the terminal device sends reporting information to the network device, where the reporting information indicates that the equivalent total bandwidth corresponds to the first equivalent total bandwidth or the second equivalent total bandwidth. Optionally, the network device receives the reporting information sent by the terminal device.

[0214] That is, the terminal device can indicate whether to use the "equivalent total bandwidth first mode" or the "equivalent total bandwidth second mode" by reporting information. The reporting information can be the first signaling or a separate signaling, which is not specifically limited.

[0215] Optionally, when the terminal device reports corresponding information, it indicates "equivalent total bandwidth second mode" or "equivalent total bandwidth first mode".

[0216] Optionally, when the terminal device does not report the corresponding information, it corresponds to the "equivalent total bandwidth second mode" or the "equivalent total bandwidth first mode".

[0217] The following is an example of reporting information transmitted via the positioning information element DL-PRS-ResourcesCapabilityPerBand-r16. This example modifies an existing information element, with the modified parts in bold (similar to the following, and no further explanation is given). The specific names used are for illustrative purposes only and may be replaced by other names.

[0218] For example, see Examples 3-6, as shown below:

[0219]

[0220] AggregationBandwidthType is translated into Chinese as: aggregation bandwidth type.

[0221] Optional. The bold new part is an optional option.

[0222] Optionally, the representation of the above "AggregationBandwidthType" and type "Type" can have different options (possibly one of the following).

[0223] 1) AggregationBandwidthType indicates two values ​​A1 and A2, corresponding to "equivalent total bandwidth first mode" and "equivalent total bandwidth second mode" respectively.

[0224] Optionally, the "AggregationBandwidthType" may be the first signaling itself, and the "AggregationBandwidthType" is used to indicate that the terminal device supports the first terminal capability. In this implementation, signaling reporting overhead can be reduced.

[0225] 2) When AggregationBandwidthType is not reported, the default is "equivalent total bandwidth first mode." When AggregationBandwidthType is reported (for example, the value is supported), the default is "equivalent total bandwidth second mode." This implementation reduces signaling reporting overhead.

[0226] 3) When AggregationBandwidthType is not reported, the default setting is "Equivalent Total Bandwidth Second Mode." When AggregationBandwidthType is reported (e.g., "Supported"), the default setting is "Equivalent Total Bandwidth First Mode." This implementation reduces signaling reporting overhead.

[0227] (4) Optionally, the reported information includes a first value or a second value, the first value indicating that the equivalent total bandwidth is the first equivalent total bandwidth, and the second value indicating that the equivalent total bandwidth is the second equivalent total bandwidth.

[0228] Optionally, the first terminal device may report a value x1 or x2, where x1 and x2 correspond to the “equivalent total bandwidth first mode” and the “equivalent total bandwidth second mode” respectively.

[0229] The following is an example of reporting information transmitted via the positioning information element NR-DL-PRS-ResourcesCapability. This example modifies an existing information element, with the modified parts in bold (similar to the subsequent examples, so no additional explanation is given). The specific names used are for illustrative purposes only and may be other names.

[0230] For example, see Examples 3-7, as shown below:

[0231]

[0232] AggregationBandwidthType is translated into Chinese as: aggregation bandwidth type.

[0233] Optional, the new part is an optional option.

[0234] Optionally, the representation of "AggregationBandwidthType" and "Type" above can have different options (possibly one of the following).

[0235] 1) AggregationBandwidthType indicates two values ​​A1 and A2, corresponding to "equivalent total bandwidth first mode" and "equivalent total bandwidth second mode" respectively.

[0236] Optionally, the "AggregationBandwidthType" may be the first signaling itself, and the "AggregationBandwidthType" is used to indicate that the terminal device supports the first terminal capability. In this implementation, signaling reporting overhead can be reduced.

[0237] 2) When AggregationBandwidthType is not reported, the default is "equivalent total bandwidth first mode." When AggregationBandwidthType is reported (for example, the value is supported), the default is "equivalent total bandwidth second mode." This implementation reduces signaling reporting overhead.

[0238] 3) When AggregationBandwidthType is not reported, the default setting is "Equivalent Total Bandwidth Second Mode." When AggregationBandwidthType is reported (e.g., "Supported"), the default setting is "Equivalent Total Bandwidth First Mode." This implementation reduces signaling reporting overhead.

[0239] (5) Optionally, when the terminal device does not send reporting information to the network device, the maximum equivalent total bandwidth of the terminal device defaults to the first equivalent total bandwidth or the second equivalent total bandwidth.

[0240] That is, when the terminal device does not report the corresponding information, the default is "equivalent total bandwidth first mode" or "equivalent total bandwidth second mode." In this implementation, the signaling reporting overhead can be reduced.

[0241] 4.2. Optionally, the maximum value of the joint bandwidth is indicated by NR-DL-PRS-ResourcesCapability or DL-PRS-ResourcesCapabilityPerBand.

[0242] (1) Optionally, the NR positioning information element NR-DL-PRS-ResourcesCapability indicates the maximum aggregate bandwidth corresponding to the first terminal capability. In this implementation, using the same maximum aggregate bandwidth capability for each frequency band or frequency band combination can reduce signaling overhead.

[0243] The following is an example of transmission via the positioning information element NR-DL-PRS-ResourcesCapability. This example modifies an existing information element, with the modified parts highlighted in bold (similar to the subsequent examples, so no further explanation is needed). The specific names used are for illustrative purposes only and may be replaced by other names.

[0244] For example, see Examples 3-8, as shown below:

[0245]

[0246]

[0247] The Chinese translation of MaxAggregationBandwidth is: maximum aggregation bandwidth.

[0248] The bolded portion is optional. Optionally, the type Type can be a numeric type or an enumeration type, whose value, as described above, indicates the maximum aggregate bandwidth supported by the terminal, as described in "MaxAggregationBandwidth." Similar meanings apply to other embodiments and are not detailed here.

[0249] Optionally, the "MaxAggregationBandwidth" may be the first signaling itself, and the "MaxAggregationBandwidth" is used to indicate that the terminal device supports the first terminal capability. In this implementation, the signaling reporting overhead can be reduced.

[0250] (2) Optionally, the NR positioning information element DL-PRS-ResourcesCapabilityPerBand indicates the maximum aggregate bandwidth corresponding to the first terminal capability. In this implementation, the positioning information element DL-PRS-ResourcesCapabilityPerBand is used to reduce signaling overhead when supporting the aggregation of positioning signals on different intra-band positioning frequency layers or different aggregation layers. At the same time, different capabilities can be provided for different frequency bands, providing flexibility for the implementation of terminal devices and enabling the design of terminal device types that adapt to various deployment scenarios.

[0251] The following is an example of transmission via the positioning information element DL-PRS-ResourcesCapabilityPerBand. This example modifies an existing information element, with the modified parts highlighted in bold (similar to the subsequent examples, so no further explanation is needed). The specific names used are for illustrative purposes only and may be replaced by other names.

[0252] For example, see Examples 3-9, as shown below:

[0253]

[0254] The Chinese translation of MaxAggregationBandwidth is: maximum aggregation bandwidth.

[0255] Optional, the new part is an optional option.

[0256] Optionally, the "MaxAggregationBandwidth" may be the first signaling itself, and the "MaxAggregationBandwidth" is used to indicate that the first terminal device supports the first terminal capability. In this implementation, signaling reporting overhead can be reduced.

[0257] 4.3. Optionally, one or more frequency band combination information is also used to indicate the maximum equivalent total bandwidth of the terminal device.

[0258] Optionally, the signaling corresponding to the band combination information may indicate the maximum aggregate bandwidth corresponding to the first terminal's capabilities. In this implementation, different capabilities are provided for different band combinations, providing flexibility for terminal device implementation and enabling the design of terminal device types that adapt to various deployment scenarios.

[0259] For example, see Examples 3-10, as shown below:

[0260] Based on Example 3-3, the band combination information bandCombinationInfomation not only indicates information about multiple frequency bands, but also may indicate information about the maximum aggregate bandwidth corresponding to the first terminal capability, for example:

[0261] MaxAggregationBandwidth Type,

[0262] It should be noted that in the above-mentioned embodiments, the bandwidth information may be information indicating the number of RBs, information indicating the number of Hz (hertz) of bandwidth, or other similar bandwidth information, without specific limitation. Moreover, the MaxAggregationBandwidth configuration method in the above-mentioned embodiments may be further expanded, for example, different maximum aggregation bandwidth information may be configured for different subcarrier spacings.

[0263] 4.4. Optionally, the method further includes: the terminal device reports a second terminal capability to the network device through a second signaling, where the second terminal capability indicates timing deviation-related information of the receiving end, and the timing deviation-related information corresponds to different carriers or different joint layers.

[0264] It is understood that the terminal device reports the second terminal capabilities to the network device via the second signaling. The second terminal capabilities indicate information related to the timing deviation of the receiving end on different carriers, different positioning frequency layers, or different aggregation layers. In this implementation, more information can be provided to the network side, allowing the network to better determine whether the terminal device needs to perform aggregation processing based on signals on multiple positioning frequency layers for a specific positioning service.

[0265] Optionally, the first signaling and the second signaling are the same signaling or different signalings.

[0266] Optionally, the first signaling and the second signaling are carried in the same layer of the same positioning signaling element. That is, the second signaling and the first signaling can be in the same layer of a positioning signaling element. It can be understood that in the above embodiment, where the coarse first signaling is newly added, the content corresponding to the second signaling can also be added, and will not be repeated here. Among them, the positioning signaling element can be NR-DL-PRS-ResourcesCapability or DL-PRS-ResourcesCapabilityPerBand.

[0267] 302. Optionally, the network device sends positioning configuration information to the terminal device based on the first terminal capability, where the positioning configuration information is used by the terminal device to perform positioning measurement. The terminal device receives the positioning configuration information sent by the network device.

[0268] 303. Optionally, the terminal device performs positioning measurement according to the positioning configuration information.

[0269] The network device sends corresponding downlink positioning signal (eg, PRS) configuration information and / or other positioning configuration information to the terminal device based on the first terminal capability reported by the terminal device. The terminal device performs positioning measurement-related operations based on the configuration information of the first network device.

[0270] It should be noted that the above embodiments can be combined, and the resulting embodiments are also within the scope of protection of the present invention. For example: an embodiment obtained by combining one or more of Embodiments {3-4, 3-5, 3-6, 3-7} and / or one of Embodiments {3-1, 3-2, 3-3} and / or one of Embodiments {3-8, 3-9}. An embodiment obtained by combining one of Embodiments {3-1, 3-2, 3-3} with any one or more of Embodiments {3-4, 3-5, 3-6, 3-7, 3-8, 3-9}.

[0271] In an embodiment of the present invention, a terminal device reports support for a first terminal capability to a network device via a first signaling message. The first terminal capability is a positioning function based on downlink positioning signal aggregation. This implements reporting of relevant UE capabilities for a solution that supports positioning functions using multiple positioning signals in combination. This new UE capability enables the UE to support signals with a larger equivalent bandwidth for positioning, which can improve positioning accuracy. By introducing new UE capabilities, high-capability terminals can provide better positioning performance.

[0272] For example, for the scenario where positioning signals are aggregated on multiple positioning frequency layers or aggregation layers that may be adopted by Rel-17, a specific terminal capability reporting method is proposed: UE corresponding capability reporting, and different calculation methods of the equivalent total bandwidth of the aggregated signal; reporting method of corresponding frequency band or frequency band combination information; reporting method of maximum aggregation bandwidth capability; reporting of timing error information corresponding to different aggregation layers or positioning frequency layers; and combination method of the above various information.

[0273] like Figure 5 FIG. 1 is a schematic diagram of an embodiment of a terminal device according to an embodiment of the present invention, which may include:

[0274] The transceiver module 501 is used to report to the network device through the first signaling that the terminal device supports the first terminal capability, where the first terminal capability is a positioning function based on the joint use of multiple downlink positioning signals.

[0275] Optionally, the first terminal capability indicates the maximum number of corresponding joint layers jointly used by multiple downlink positioning signals.

[0276] Optionally, the maximum number of layers of the combined layer is 2, 3 or 4.

[0277] Optionally, the maximum number of layers of the joint layer indicated by the first field is 2, 3 or 4; or

[0278] The maximum number of layers of the joint layer is indicated by the second field. The value of the maximum number of layers of the joint layer indicated by the second field under default conditions is 2. The value of the maximum number of layers of the joint layer indicated by the second field under non-default conditions is 3 or 4.

[0279] Optionally, different joint layers occupy different frequency domain resources.

[0280] Optionally, the same joint layers may have the same values ​​for some or all of the following configuration parameters, including:

[0281] Subcarrier spacing, cyclic prefix, starting physical resource block, comb size value, signal bandwidth or resource bandwidth, and frequency position information of reference resource block.

[0282] Optionally, when the first terminal capability does not indicate the maximum number of layers of the corresponding joint layer used in conjunction with multiple downlink positioning signals, the maximum number of layers of the joint layer defaults to 2.

[0283] Optionally, the transceiver module 501 is further used to report the second terminal capability to the network device through the second signaling, where the second terminal capability indicates the timing deviation related information of the receiving end, and the timing deviation related information corresponds to different carriers or different joint layers.

[0284] Optionally, the first signaling and the second signaling are the same signaling or different signalings.

The terminal device of the embodiment of the present application can implement any one of the implementation modes of the above method. Figure 7 FIG2 is a schematic diagram of another embodiment of a terminal device according to an embodiment of the present invention. The terminal device is described by taking a mobile phone as an example and may include: a radio frequency (RF) circuit 710, a memory 720, an input unit 730, a display unit 740, a sensor 750, an audio circuit 760, a wireless fidelity (WiFi) module 770, a processor 780, and a power supply 790. Among them, the RF circuit 710 includes a receiver 714 and a transmitter 712. Those skilled in the art will understand that Figure 7 The mobile phone structure shown in the figure does not constitute a limitation to the mobile phone, and may include more or fewer components than shown in the figure, or combine certain components, or arrange the components differently.

[0361] The following combination Figure 7 A detailed introduction to the various components of a mobile phone:

[0362] The RF circuit 710 can be used to receive and send signals during information transmission or calls. In particular, after receiving the downlink information from the base station, it is sent to the processor 780 for processing; in addition, the designed uplink data is sent to the base station. Generally, the RF circuit 710 includes but is not limited to an antenna, at least one amplifier, a transceiver, a coupler, a low noise amplifier (LNA), a duplexer, etc. In addition, the RF circuit 710 can also communicate with the network and other devices through wireless communication. The above-mentioned wireless communication can use any communication standard or protocol, including but not limited to the global system of mobile communications (GSM), general packet radio service (GPRS), code division multiple access (CDMA), wideband code division multiple access (WCDMA), long term evolution (LTE), email, short messaging service (SMS), etc.

[0363] The memory 720 can be used to store software programs and modules. The processor 780 executes the various functional applications and data processing of the mobile phone by running the software programs and modules stored in the memory 720. The memory 720 can mainly include a program storage area and a data storage area. The program storage area can store an operating system and at least one application required for a function (such as a sound playback function, an image playback function, etc.); the data storage area can store data created based on the use of the mobile phone (such as audio data, a phone book, etc.). In addition, the memory 720 can include high-speed random access memory and non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage device.

[0364] The input unit 730 can be used to receive input digital or character information, and to generate key signal input related to the user settings and function control of the mobile phone. Specifically, the input unit 730 may include a touch panel 731 and other input devices 732. The touch panel 731, also known as a touch screen, can collect user touch operations on or near it (such as operations performed by the user using any suitable object or accessory such as a finger, stylus, etc. on or near the touch panel 731) and drive the corresponding connection device according to a pre-set program. Optionally, the touch panel 731 may include two parts: a touch detection device and a touch controller. Among them, the touch detection device detects the user's touch direction and detects the signal caused by the touch operation, and transmits the signal to the touch controller; the touch controller receives the touch information from the touch detection device and converts it into touch point coordinates, which are then sent to the processor 780. It can also receive commands sent by the processor 780 and execute them. In addition, the touch panel 731 can be implemented using various types such as resistive, capacitive, infrared and surface acoustic wave. In addition to the touch panel 731, the input unit 730 may further include other input devices 732. Specifically, the other input devices 732 may include, but are not limited to, one or more of a physical keyboard, function keys (such as volume control keys, switch keys, etc.), a trackball, a mouse, and a joystick.

[0365] The display unit 740 can be used to display information input by the user or information provided to the user and various menus of the mobile phone. The display unit 740 may include a display panel 741. Optionally, the display panel 741 may be configured in the form of a liquid crystal display (LCD), an organic light-emitting diode (OLED), etc. Further, the touch panel 731 may cover the display panel 741. When the touch panel 731 detects a touch operation on or near it, it is transmitted to the processor 780 to determine the type of touch event. Subsequently, the processor 780 provides corresponding visual output on the display panel 741 according to the type of touch event. Although in Figure 7 In the embodiment, the touch panel 731 and the display panel 741 are used as two independent components to realize the input and output functions of the mobile phone, but in some embodiments, the touch panel 731 and the display panel 741 can be integrated to realize the input and output functions of the mobile phone.

[0366] The mobile phone may also include at least one sensor 750, such as a light sensor, a motion sensor, and other sensors. Specifically, the light sensor may include an ambient light sensor and a proximity sensor, wherein the ambient light sensor may adjust the brightness of the display panel 741 according to the brightness of the ambient light, and the proximity sensor may turn off the display panel 741 and / or the backlight when the mobile phone is moved to the ear. As a type of motion sensor, the accelerometer sensor can detect the magnitude of acceleration in all directions (generally three axes), and can detect the magnitude and direction of gravity when stationary. It can be used for applications that identify the posture of the mobile phone (such as horizontal and vertical screen switching, related games, magnetometer posture calibration), vibration recognition related functions (such as pedometer, tapping), etc.; as for other sensors that the mobile phone can also be configured with, such as gyroscopes, barometers, hygrometers, thermometers, infrared sensors, etc., they will not be described here.

[0367] Audio circuit 760, speaker 761, and microphone 762 provide an audio interface between the user and the phone. Audio circuit 760 converts received audio data into electrical signals and transmits them to speaker 761, which then converts them into sound signals for output. Microphone 762, on the other hand, converts collected sound signals into electrical signals, which are then received by audio circuit 760 and converted into audio data. The audio data is then processed by processor 780 and transmitted to, for example, another phone via RF circuit 710, or stored in memory 720 for further processing.

[0368] WiFi is a short-range wireless transmission technology. The mobile phone can help users send and receive emails, browse the web and access streaming media through the WiFi module 770. It provides users with wireless broadband Internet access. Figure 7 A WiFi module 770 is shown, but it is understandable that it is not an essential component of the mobile phone and can be omitted as needed without changing the essence of the invention.

[0369] Processor 780 is the control center of the mobile phone, connecting all parts of the mobile phone using various interfaces and circuits. By running or executing software programs and / or modules stored in memory 720 and accessing data stored in memory 720, it performs various functions of the mobile phone and processes data, thereby providing overall monitoring of the mobile phone. Optionally, processor 780 may include one or more processing units; preferably, processor 780 may integrate an application processor and a modem processor, wherein the application processor primarily handles the operating system, user interface, and application programs, while the modem processor primarily handles wireless communications. It is understood that the modem processor may not be integrated into processor 780.

[0370] The mobile phone also includes a power supply 790 (such as a battery) for supplying power to various components. Preferably, the power supply can be logically connected to the processor 780 via a power management system, thereby enabling the power management system to manage charging, discharging, and power consumption. Although not shown, the mobile phone may also include a camera, a Bluetooth module, etc., which will not be described in detail here.
