Abstract
Description
Technical Field
[0001] The present application relates to the field of communication technology, and more specifically, to an information reporting method and a communication device. Background Art
[0002] In the field of new radio (NR) positioning, NR, as an emerging radio technology, can have significant value in enhancing positioning capabilities. For example, in the 3rd Generation Partnership Project (3GPP) standard, multiple positioning technologies can be supported, including downlink-time difference of arrival (DL-TDOA), (downlink-angle of departure, DL-AOD), uplink-time difference of arrival (UL-TDOA), (uplink-angle of arrival, UL-AOA), multi-station round trip time (multi-RTT) and other positioning technologies. These positioning technologies measure the positioning reference signal through the coordination of the sender and receiver, and perform subsequent positioning calculations based on the measurement results to achieve the positioning function. Among them, the positioning accuracy is related to the bandwidth strength of the positioning reference signal. The larger the bandwidth, the higher the time resolution, the stronger the multipath resolution, and the more accurately the arrival time of the first path can be identified, thereby reducing the position estimation error.
[0003] In order to further improve positioning accuracy, the 3GPP standards organization proposed a research topic based on intra-band large bandwidth positioning in the R18 standard evolution. For example, a larger bandwidth can be synthesized by jointly processing positioning reference signals on multiple carriers. At the same time, the problem that arises is that the terminal needs to report the ability to support positioning bandwidth aggregation, so there is an urgent need for an information reporting method to control the signaling overhead when the terminal device reports the positioning bandwidth aggregation capability. Summary of the invention
[0004] The present application provides an information reporting method and a communication device, which can control signaling overhead when a terminal device reports positioning bandwidth aggregation capability.
[0005] In a first aspect, a method for reporting information is provided, which can be executed by a terminal device, or by a chip or circuit configured in the terminal device, or by a logic module or software that can implement all or part of the functions of the terminal device. This application does not limit this.
[0006] The method comprises: sending information of a first frequency band combination, wherein the first frequency band combination comprises at least one frequency band, wherein the information of the first frequency band combination is used to indicate a feature set supported by the terminal device on the at least one frequency band, wherein the feature set comprises a communication feature set combination and a positioning feature set combination, wherein the communication feature set combination is used to indicate a carrier aggregation capability of data communication supported by the terminal device in the first frequency band combination, and the positioning feature set combination is used to indicate a bandwidth aggregation capability of a positioning reference signal supported by the terminal device in the first frequency band combination; and receiving first configuration information, wherein the first configuration information is configuration information of the positioning reference signal determined according to the information of the first frequency band combination, and the first configuration information is used for the terminal device to send the positioning reference signal.
[0007] For terminal devices, data communication and positioning are two services that can exist and operate independently. In this technical solution, the information of the first frequency band combination reported by the UE not only includes a data communication feature set combination for indicating the carrier aggregation capability of data communication, but also introduces a positioning feature set combination. The positioning feature set combination is used to indicate the bandwidth aggregation capability of the positioning reference signal supported by the terminal device in the first frequency band combination, avoiding reporting the frequency band combination twice, thereby saving the overhead caused by repeated reporting of the frequency band combination and reducing the signaling overhead when reporting UE capabilities.
[0008] In combination with the first aspect, in certain implementations of the first aspect, the positioning feature set combination is only used to indicate that the terminal device supports the bandwidth aggregation capability of the positioning reference signal in the first frequency band combination.
[0009] In this technical solution, the positioning feature set combination is only used to indicate the bandwidth aggregation capability of the positioning reference signal supported by the terminal device, that is, the feature set included in the positioning feature set combination is only used to indicate positioning-related features, and is not used to indicate the carrier aggregation capability supported by the terminal device for communication. It can be understood that carrier aggregation for communication may require stronger UE processing capabilities, or the processing complexity of data communication is greater, and the hardware cost is relatively high; relatively speaking, positioning does not require processing steps such as encoding / decoding, so the bandwidth aggregation for positioning may be relatively less demanding on hardware and easier to handle. In summary, the UE's capability requirements for reporting communications and reporting positioning may be different. For example, the UE may only support bandwidth aggregation for positioning, but not carrier aggregation for data communication. Therefore, this implementation method can be adapted to scenarios where the UE reports capabilities regarding different capabilities for communication and positioning.
[0010] In combination with the first aspect, in certain implementations of the first aspect, the communication feature set combination is only used to indicate the carrier aggregation capability of the terminal device to support data communication in the first frequency band combination.
[0011] In this technical solution, the communication feature set combination is only used to indicate the carrier aggregation capability of data communication, and is not used to indicate the bandwidth aggregation capability of the positioning reference signal. Therefore, it is possible to indicate the carrier aggregation capability of data communication and the bandwidth aggregation capability of positioning respectively through two feature set combinations, which can increase the flexibility of the indication method and adapt to different scenarios.
[0012] In combination with the first aspect, in certain implementations of the first aspect, the communication feature set combination and the positioning feature set combination are used to indicate the bandwidth aggregation capability of the positioning reference signal supported by the terminal device in the first frequency band combination.
[0013] In this technical solution, the bandwidth aggregation capability of the positioning reference signal is indicated based on the superposition of the communication feature set combination and the positioning feature set combination. That is to say, some feature sets in the communication feature set combination can be used to indicate the bandwidth aggregation capability of positioning. Accordingly, this part of the feature set may not be carried in the positioning feature set combination, thereby reducing the characteristics of the positioning feature set combination and reducing signaling overhead.
[0014] In combination with the first aspect, in certain implementations of the first aspect, the bandwidth aggregation capability of the positioning reference signal includes the number of the positioning reference signals supported for aggregation by the terminal device and the bandwidth of each of the positioning reference signals.
[0015] In combination with the first aspect, in certain implementations of the first aspect, the carrier aggregation capability of data communication includes the number of carrier aggregations supported by the terminal device for communication and the bandwidth of each carrier.
[0016] In combination with the first aspect, in certain implementations of the first aspect, the positioning feature set combination includes a feature set corresponding to each frequency band in the at least one frequency band, each of the feature sets includes a carrier aggregation feature supported by the terminal device, and the carrier aggregation feature includes features related to the positioning reference signal and features related to communication.
[0017] In combination with the first aspect, in some implementations of the first aspect, the positioning feature set combination also includes a first feature set, and the first feature set is only used to carry features related to the positioning reference signal supported by the terminal device.
[0018] In this technical solution, a positioning feature set (first feature set) is introduced. This feature set only contains uplink positioning-related capabilities, or there is no need to report features unrelated to positioning, or there is no need to report capabilities related to data communication, thereby reducing the signaling overhead when reporting terminal device capabilities and achieving capability decoupling of positioning bandwidth aggregation and data carrier aggregation.
[0019] In combination with the first aspect, in certain implementations of the first aspect, the information of the first frequency band combination is also used to indicate the maximum aggregated number and / or the maximum aggregated bandwidth of the positioning reference signals supported by the terminal device.
[0020] In this technical solution, the maximum aggregated number of positioning reference signals and / or the maximum aggregated bandwidth supported by the terminal device can also be indicated in the first frequency band combination without being restricted by the carrier aggregation capability value of the communication, thereby achieving flexible positioning bandwidth aggregation capability reporting.
[0021] In combination with the first aspect, in certain implementations of the first aspect, the first frequency band combination also includes a first field, and the first field is used to indicate the maximum aggregated number and / or the maximum aggregated bandwidth of the positioning reference signals supported by the terminal device.
[0022] In this technical solution, by adding a first field in the first frequency band combination to indicate the maximum aggregation number and / or the maximum aggregation bandwidth of positioning reference signals supported by the terminal device, the UE can flexibly report which carriers it supports bandwidth aggregation for positioning, the number of bandwidths it wants to aggregate, and the size of the bandwidth involved in the aggregation, without being restricted by the carrier aggregation capability value of the communication. This improves the flexibility of reporting the positioning bandwidth aggregation capability, and also increases the flexibility of network devices in configuring positioning reference signals for bandwidth aggregation.

In this technical solution, the network receives information on the first frequency band combination reported by the terminal device. The information on the first frequency band combination not only includes a data communication feature set combination for indicating the carrier aggregation capability of data communication, but also introduces a positioning feature set combination. The positioning feature set combination is used to indicate the bandwidth aggregation capability of the positioning reference signal supported by the terminal device in the first frequency band combination, avoiding reporting the carrier aggregation capability of data communication and the bandwidth aggregation capability of positioning separately by reporting the frequency band combination list twice, thereby saving the overhead caused by repeated reporting of the frequency band combination and reducing the signaling overhead when the terminal device reports the capability.

Therefore, it is possible to indicate the carrier aggregation capability of data communication and the bandwidth aggregation capability of positioning respectively through two feature set combinations, which can increase the flexibility of the indication method and adapt to different scenarios.
[0029] In this technical solution, the communication feature set combination is not used to indicate the bandwidth aggregation capability of the positioning reference signal.

[0034] In combination with the second aspect, in some implementations of the second aspect, the positioning feature set combination also includes a first feature set, and the first feature set is only used to carry features related to the positioning reference signal supported by the terminal device.

[0036] In combination with the second aspect, in certain implementations of the second aspect, the first frequency band combination also includes a first field, and the first field is used to indicate the maximum aggregated number and / or the maximum aggregated bandwidth of the positioning reference signals supported by the terminal device.
[0037] The beneficial effects of the second aspect can be referred to the first aspect, and for the sake of brevity, they will not be repeated here.

[0040] According to the technical solution, indication information (the second field) is directly introduced at the frequency band parameter list level to indicate the bandwidth aggregation capability of the positioning reference signal supported by the terminal device, and parameters for the bandwidth aggregation of the positioning reference signal are added, such as bandwidthclass, supportedSubcarrierSpacingUL, and supportedBandwidthUL.

Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0118] As an example but not limitation, in the embodiments of the present application, the terminal device may also be a wearable device. Wearable devices may also be referred to as 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 powerful functions achieved through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-sized, and fully or partially independent of smartphones, such as smart watches or smart glasses, as well as devices 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 types of smart bracelets and smart jewelry for vital sign monitoring.
[0119] In addition, in the embodiments of the present application, the terminal device can also be a terminal device in an IoT system. IoT is an important part of the future development of information technology. Its main technical feature is to connect objects to the network through communication technology, thereby realizing an intelligent network that interconnects people and machines and things.
[0120] It should be noted that the terminal device and the access network device may communicate with each other using a certain air interface technology (such as but not limited to NR or LTE technology, etc.). The terminal devices may also communicate with each other using a certain air interface technology (such as but not limited to NR or LTE technology, etc.).
[0121] In the embodiment of the present application, the device for realizing the function of the terminal device can be the terminal device, or it can be a device that can support the terminal device to realize the function, such as a chip system or a chip, which can be installed in the terminal device. In the embodiment of the present application, the chip system can be composed of a chip, or it can include a chip and other discrete devices.
[0122] The access network (AN) device in this application can provide the function of accessing the communication network for authorized users in a specific area, and can specifically include wireless network devices in the 3rd generation partnership project (3GPP) network and access points in non-3GPP networks. For the convenience of description, the following uses AN devices to represent.
[0123] AN equipment can be different wireless access technologies. There are two types of wireless access technologies at present: 3GPP access technology (for example, the wireless access technology used in the third generation (3rd generation, 3G), fourth generation (4th generation, 4G) or 5G system), or the future 6G network, and non-3GPP (non-3GPP) access technology, such as open access network (open RAN, O-RAN or ORAN), cloud radio access network (cloud radio access network, CRAN), or two or more of the above networks. 3GPP access technology refers to access technology that complies with 3GPP standard specifications. For example, the access network equipment in the 5G system is called the next generation Node Basestation (gNB) or RAN equipment. Non-3GPP access technology can include air interface technology represented by access point (AP) in wireless fidelity (WiFi), worldwide interoperability for microwave access (WiMAX), code division multiple access (CDMA), etc. AN equipment can allow terminal devices and the 3GPP core network to interconnect and communicate using non-3GPP technologies.
[0124] AN equipment is responsible for wireless resource management, quality of service (QoS) management, data compression and encryption, etc. on the air interface side. AN equipment provides access services for terminal equipment, and then completes the forwarding of control signals and user data between terminal equipment and the core network.
[0125] AN equipment can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation nodeB (gNB) in the fifth generation (5G) mobile communication system, a next generation base station in the sixth generation (6G) mobile communication system, a base station in a future mobile communication system, a wireless fidelity (WiFi) system, a long range radio (LoRa) system, or an access node in a connected vehicle system. AN equipment can also be a module or unit that performs some of the functions of a base station, for example, a centralized unit (CU), a distributed unit (DU), or a radio unit (RU). The CU here completes the functions of the radio resource control protocol and the packet data convergence protocol (PDCP) of the base station, and can also complete the function of the service data adaptation protocol (SDAP); the DU completes the functions of the radio link control layer and the medium access control (MAC) layer of the base station, and can also complete the functions of part of the physical layer or all of the physical layer. For the specific description of the above-mentioned various protocol layers, please refer to the relevant technical specifications of the third generation partnership project (3GPP). CU and DU can be set separately, or they can also be included in the same network element, such as the baseband unit (BBU). RU can be included in a radio frequency device or a radio frequency unit, such as a remote radio unit (RRU), an active antenna unit (AAU) or a remote radio head (RRH). In different systems, CU, DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be referred to as O-CU (open CU), DU may also be referred to as O-DU, and RU may also be referred to as O-RU. Any unit in the CU (or CU-CP, CU-UP), DU and RU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.The wireless access network device may be a macro base station (eg. Figure 1 110a), or a micro base station or an indoor station (such as Figure 1 110b), may also be a relay node or a donor node, etc. The embodiments of the present application do not limit the specific technology and specific device form adopted by the wireless access network device. For ease of description, network device is used as the abbreviation of wireless access network device, and base station is used as an example of wireless access network device.
[0126] The functions of other network element devices involved are as follows:
[0127] Location management function (LMF): A device or component deployed in the core network to provide positioning functions for UE.
[0128] eNB: A device deployed in a radio access network that provides wireless communication functions for UEs. eNBs can include various forms of macro base stations, micro base stations (also called small stations), relay stations, access points, wearable devices, and vehicle-mounted devices. eNBs can also be transmission and reception points (TRPs).
[0129] gNB: A device deployed in a radio access network to provide wireless communication functions for UEs. gNBs can include various forms of macro base stations, micro base stations (also called small stations), relay stations, access points, wearable devices, and vehicle-mounted devices. gNB can also be a TRP, a transmission measurement function (TMF). gNB can include a central unit (CU) and a distributed unit (DU) integrated on the gNB.
[0130] In order to facilitate understanding of the embodiments of the present application, relevant terms in the present application are first explained.
[0131] 1. Frequency band combination
[0132] When reporting capabilities, the UE uses the frequency band combination to characterize the capabilities supported by the UE. The frequency band combination refers to the combination of different frequency bands, or it can include only one frequency band. The combination of different frequency bands includes the features corresponding to different frequency bands. For example, if the UE reports the combination of frequency band 1 and frequency band 2, it means that the UE supports the features corresponding to frequency band 1 and the features corresponding to frequency band 2.
[0133] The characteristics corresponding to the frequency band are used to indicate the capabilities of the UE, and each characteristic corresponds to a characteristic value. For example, the characteristic may be a parameter characteristic such as the number of carriers supported by the UE, the bandwidth size of each carrier, and the subcarrier spacing on the corresponding carrier. This embodiment of the application is not limited to this.
[0134] The feature corresponding to the frequency band may be a feature of the data carrier aggregation capability that the UE only supports, or a feature of the positioning bandwidth aggregation capability that the UE only supports, or the feature may support both the data carrier aggregation capability and the positioning bandwidth aggregation capability. This embodiment of the application is not limited to this.
[0135] In an optional understanding, the frequency band combination may only support data carrier aggregation capability, may only support positioning bandwidth aggregation capability, or may support both data carrier aggregation capability and positioning bandwidth aggregation capability. This embodiment of the application does not limit this.
[0136] 2. Data carrier aggregation capability
[0137] The data carrier aggregation capability is used to indicate the carrier aggregation capability supported by the UE for data communication. For example, the carrier aggregation capability may include the number of carrier aggregations supported by the UE for communication and the bandwidth of each carrier, etc., which is not limited in the embodiments of the present application.
[0138] 3. Positioning bandwidth aggregation capability
[0139] The positioning bandwidth aggregation capability is used to indicate the bandwidth aggregation capability for positioning supported by the UE, or the bandwidth aggregation capability of the positioning reference signal supported by the UE. For example, the bandwidth aggregation capability may include the number of positioning reference signals supported by the UE for aggregation and the bandwidth of each positioning reference signal, etc., which is not limited in the embodiments of the present application.
[0140] Among them, the positioning reference signal is carried in the carrier, so the bandwidth aggregation of the positioning reference signal can also be understood as the carrier aggregation of the positioning reference signal. The embodiment of the present application does not limit the name of this term, and the embodiment of the present application takes the bandwidth aggregation of the positioning reference signal as an example for explanation.
[0141] In the present application, the positioning reference signal can be a sounding reference signal (SRS), a sidelink-position reference signal (SL-PRS), or other reference signals used for positioning. The positioning reference signal can be used for uplink positioning or downlink positioning, and the embodiments of the present application are not limited to this.
[0142] In the field of NR positioning, NR, as an emerging radio technology, can have significant value in enhancing positioning capabilities. For example, in the existing 3GPP standard, multiple positioning technologies can be supported, including DL-TDOA, DL-AOD, UL-TDOA, UL-AOA, multi-RTT and other positioning technologies. The premise for these positioning technologies to achieve the positioning function is that the sender and receiver need to coordinate to measure the positioning reference signal and perform subsequent positioning calculations based on the measurement results. Among them, the positioning accuracy is related to the bandwidth strength of the positioning reference signal. The larger the bandwidth, the higher the time resolution and the stronger the multipath resolution, which can more accurately identify the arrival time of the first path, thereby reducing the position estimation error.
[0143] Currently, in order to further improve positioning accuracy, the 3GPP standard organization has proposed a research topic based on intra-band large bandwidth positioning in the R18 standard evolution. For example, a larger bandwidth can be synthesized by jointly processing positioning reference signals on multiple carriers.
[0144] At the same time, the problem that arises is that for terminal devices, data communication and positioning are two services that can exist and operate independently. However, when the terminal device reports its capabilities, it needs to report the carrier aggregation capability of communication and the bandwidth aggregation capability of positioning at the same time. For example, the terminal needs to report all frequency band combinations that currently support bandwidth aggregation and the corresponding characteristics, as well as all frequency band combinations that support positioning bandwidth aggregation and the corresponding characteristics, which will result in excessive signaling overhead.
[0145] Figure 2 It is a schematic diagram of a reporting method in which carrier aggregation for UE reporting communication and carrier aggregation for positioning are decoupled.
[0146] Figure 2 (a) shows the reporting method when the current UE reports the carrier aggregation capability.
[0147] The UE reports a band combination list, which may include multiple band combinations, such as Figure 2 The band combination-1 and band combination-2 shown in (a) should be understood that the band combination list may also include multiple other band combinations, which is not limited in this embodiment of the present application.
[0148] Each band combination includes multiple fields, each of which indicates a different feature value. For example, in band combination-1, it includes a band list, feature set combination-1, evolved universal terrestrial radio access (EUTRA) aggregation parameters (ca-parameters EUTRA), NR aggregation parameters (ca-parameters NR), mrdc parameters (mrdc-parameters), supported bandwidth combination set (supported band width combination set), etc.
[0149] Each frequency band list may include at least one frequency band parameter set, for example, Figure 2 The band parameter set-1 (band parameters-1) and the band parameter set-2 (band parameters-2) shown in (a) of FIG. The band parameter set may include multiple fields, for example, the band parameter set-1 includes the NR band (band NR), the bandwidth of the bandwidth aggregation supported for downlink in NR (ca-band width class DL-NR), the bandwidth of the bandwidth aggregation supported for uplink in NR (ca-BandwidthClassUL-NR), the carrier switch of the positioning reference signal (srs-carrier switch), etc.
[0150] It should be noted that the above Figure 2 (a) includes the capability values corresponding to the features under all the reported frequency band combinations, and the current feature defaults to the capability value when the UE performs data carrier aggregation, that is, the above Figure 2 All the fields included in (a) indicate that the feature supports the carrier aggregation capability of communication.
[0151] Therefore, in order to report the ability to locate bandwidth aggregation, a set of capability lists can be re-reported, such as Figure 2 The band combination list (BandCombinationListPosSRS) of the positioning reference signal shown in (b) in FIG. Figure 2 For all band combinations in (a), report the positioning bandwidth aggregation capability values (ca-BandwidthClassPosSRS) under these combinations.
[0152] It is understandable that the above Figure 2The characteristic value corresponding to the frequency band combination in (a) is used for carrier aggregation for UE communication. Figure 2 The characteristic value corresponding to the frequency band combination in (b) is used for bandwidth aggregation of positioning reference signals by UE. Figure 2 The frequency band combination in (a) and Figure 2 The frequency band combinations in (b) correspond one to one, that is, for the frequency band combinations under the same frequency band combination list, two groups of characteristic values are reported respectively, one group of characteristic values is used for data communication, and the other group of characteristic values is used for bandwidth aggregation of positioning reference signals.
[0153] In this reporting method, there may be many frequency band combinations, namely Figure 2 The band combination list in (a) includes multiple band combinations, for example, {band-1, band-2} is one combination, and {band-2, band-3} is another combination. For multiple band combinations in the same band combination list, two sets of characteristic values need to be reported separately. Although the UE can decouple the data carrier aggregation capability and the positioning bandwidth aggregation capability, it will greatly increase the signaling overhead of the UE reporting capability.
[0154] Furthermore, many features need to be reported in each frequency band combination, some of which are not necessary for positioning bandwidth aggregation. However, as long as the feature is reported, it will occupy memory (even if the reported value is 0, it will occupy signaling bits). Therefore, for this set of positioning features, there will be many unnecessary feature values, resulting in unnecessary signaling overhead.
[0155] In view of this, an embodiment of the present application provides an information reporting method, which saves signaling overhead when a terminal device reports its capabilities.
[0156] The solution of this application is described in detail below.
[0157] Figure 3 It is a schematic flowchart of an information reporting method 300 provided in an embodiment of the present application.
[0158] S310, the terminal device sends information about the first frequency band combination to the network device.
[0159] The first frequency band combination includes at least one frequency band.
[0160] The information of the first frequency band combination is used to indicate a feature set supported by the UE on the at least one frequency band.
[0161] First, the feature set is described.
[0162] The feature set includes at least one feature value supported by the UE, for example, the number of carriers supported by the UE, the bandwidth of each carrier, the corresponding subcarrier spacing on the carrier and other parameter features.
[0163] In a possible implementation manner, the feature set includes a communication feature set combination and a positioning feature set combination.
[0164] The communication feature set combination is used to indicate the carrier aggregation capability of data communication supported by the UE in the first frequency band combination.
[0165] Exemplarily, the carrier aggregation capability of data communication includes the number of carrier aggregations supported by the UE for communication and the bandwidth of each carrier.
[0166] The positioning feature set combination is used to indicate the bandwidth aggregation capability of the positioning reference signal supported by the UE in the first frequency band combination.
[0167] Exemplarily, the bandwidth aggregation capability of the positioning reference signal includes the number of positioning reference signals supported for aggregation by the UE and the bandwidth of each positioning reference signal.
[0168] It can be understood that in this application, for the first frequency band combination, the corresponding feature set includes not only a communication feature set combination, but also a positioning feature set combination. In other words, the information of the first frequency band combination reported by the UE includes two sets of feature sets, one set is used to indicate the carrier aggregation capability of data communication supported by the UE, and the other set is used to indicate the bandwidth aggregation capability of positioning supported by the UE.
[0169] The following combination Figure 4 The information reporting framework schematic diagram shown provides a detailed description of the feature set of the present application.
[0170] Figure 4 A schematic diagram of an information reporting framework is shown. Figure 4 Compared to Figure 2 The UE reporting method shown is Figure 2 Based on (a), the positioning feature set combination is introduced into the frequency band combination information, such as Figure 4 The positioning feature set combination (feature set combination Pos SRS) shown in
[0171] The information or parameter feature names in the information reporting framework in the following embodiments are merely exemplary and are not limited to these in the embodiments of the present application.
[0172] It should be understood that the positioning feature set combination can be reported in each frequency band combination to indicate whether the UE supports the bandwidth aggregation capability of the positioning reference signal in the current frequency band combination.
[0173] It should be noted that the communication feature set combination can also be used to indicate the bandwidth aggregation capability of the positioning reference signal supported by the UE, and the positioning feature set combination can also be used to indicate the carrier aggregation capability of the data communication supported by the UE.
[0174] In one embodiment, the positioning feature set combination is only used to indicate the bandwidth aggregation capability of the UE to support the positioning reference signal in the first frequency band combination.
[0175] In this case, the features in the positioning feature set combination do not support the carrier aggregation capability of data communication.
[0176] Exemplarily, in this feature set, the communication feature set combination can be used to indicate the carrier aggregation capability of data communication and the bandwidth aggregation capability of positioning reference signals supported by the UE, and the positioning feature set combination is only used to indicate the bandwidth aggregation capability of positioning reference signals supported by the UE.
[0177] It can be understood that, in this case, the communication feature set combination and the positioning feature set combination are used to indicate the bandwidth aggregation capability of the positioning reference signal supported by the UE in the first frequency band combination, or in other words, the bandwidth aggregation capability of the positioning reference signal supported by the UE in the first frequency band is jointly indicated by the communication feature set combination and the positioning feature set combination. It can also be said that the features in the communication feature set combination and the features in the positioning feature set combination are superimposed to indicate the bandwidth aggregation capability of the positioning reference signal.
[0178] It should be understood that, in this case, some features can be reduced in the positioning feature set combination, that is, these features are reflected in the communication feature set combination.
[0179] An optional understanding is that the introduction of the above positioning feature set combination can be superimposed on the existing data feature set combination.
[0180] Figure 5 A schematic diagram of a logical framework for information reporting is shown. In the figure, the communication feature set combination and the positioning feature set combination can be superimposed to indicate the bandwidth aggregation capability of the positioning reference signal supported by the UE.
[0181] For the case of superposition: In this case, the size and shape of the positioning feature set combination and the data feature set combination are the same.
[0182] Figure 5 The band combination-1 in can be Figure 4 The frequency band combination shown in-1.
[0183] like Figure 5 As shown, Figure 5There are three bands in the frequency band combination -1, namely band-1, band-2, and band-3. The frequency band combination -1 not only reports the data feature set combination FeatureSetCombination-1, but also reports the positioning feature set combination FeatureSetCombinationPosSRS. For each band, it contains three feature sets, that is, the number of feature sets in the data feature set combination is the same as the number of feature sets in the positioning feature set combination, and the number of feature sets between the three bands is also the same; at this time, superimposed use refers to adding the number of carriers (component carrier, CC) reported in the feature set in the data feature set combination and the number of carriers reported in the feature set in the positioning feature set combination as the number of CCs of the positioning bandwidth aggregation that the UE can support (or the number of positioning reference signals, assuming that one positioning reference signal is sent on each CC).
[0184] Taking band-3 as an example, assuming that the UE reports 1 CC in FeatureSet-1 of FeatureSetCombination-1 (this means that only one CC data transmission is supported on this band), and then reports 2 CCs in FeatureSet-6 of FeatureSetCombinationPosSRS, then the UE can actually support positioning bandwidth aggregation of 3 CCs, because for positioning, the contents of the above two feature set combinations are reported in a superimposed manner.
[0185] Figure 5 The frequency bands and feature sets shown in the frequency band combination are only exemplary and are not limited to the embodiments of the present application.
[0186] In one approach, the communication feature set combination is only used to indicate the carrier aggregation capability of data communication supported by the UE in the first frequency band combination.
[0187] Exemplarily, in the feature set, the communication feature set combination can be used only to indicate the carrier aggregation capability of data communication supported by the UE, and the positioning feature set combination is used only to indicate the bandwidth aggregation capability of positioning reference signals supported by the UE.
[0188] It can be understood that, in this case, the bandwidth aggregation capability of the positioning reference signal supported by the UE in the first frequency band is only indicated by the positioning feature set combination alone, and has no association with the communication feature set combination. Similarly, the carrier aggregation capability of the data communication supported by the UE in the first frequency band is only indicated by the communication feature set combination alone, and has no association with the positioning feature set combination. That is, the communication feature set combination and the positioning feature set combination individually indicate characteristics and do not affect each other.
[0189] The signal feature set combination is only used to indicate the carrier aggregation capability of data communication, and is not used to indicate the bandwidth aggregation capability of the positioning reference signal. Therefore, it is possible to indicate the carrier aggregation capability of data communication and the bandwidth aggregation capability of positioning respectively through two feature set combinations, which can increase the flexibility of the indication method and adapt to different scenarios.
[0190] An optional understanding is that the introduction of the above positioning feature set combination can be used separately with the existing data feature set combination.
[0191] Figure 6 A schematic diagram of a logical framework for information reporting is shown. In the figure, the communication feature set combination and the positioning feature set combination can independently indicate the carrier aggregation capability of data communication and the bandwidth aggregation capability of positioning reference signals supported by the UE.
[0192] For the case where they are used separately: In this case, the sizes of the positioning feature set combination and the data feature set combination can be different.
[0193] Figure 6 The band combination-1 in can be Figure 4 The frequency band combination shown in-1.
[0194] like Figure 6 As shown in the figure, there are three bands in the frequency band combination-1, namely band-1, band-2, and band-3. This band combination not only reports the data feature set combination FeatureSetCombination-1, but also reports the positioning feature set combination FeatureSetCombinationPosSRS. Figure 5 The difference is that the feature set combination for data contains 3 feature sets, while the feature set combination for positioning contains only 2 feature sets. At this time, the term "used alone" refers to the number of carriers (CC / carrier) reported in the feature set in the data feature set combination, which only represents the number of carriers used for data communication; the number of carriers reported in the feature set in the positioning feature set combination only represents the number of CCs of the positioning bandwidth aggregation that the UE can support (or the number of positioning reference signals, assuming that one positioning reference signal is sent on each CC).
[0195] Taking band-3 as an example, assuming that the UE reports 1 CC in FeatureSet-1 of FeatureSetCombination-1 (this means that only one CC data transmission is supported on this band), and then reports 2 CCs in FeatureSet-6 of FeatureSetCombinationPosSRS, then the UE can actually only support positioning bandwidth aggregation of 2 CCs, because the contents of the above two feature set combinations are irrelevant for positioning.
[0196] Figure 6 The frequency bands and feature sets shown in the frequency band combination are only exemplary and are not limited to the embodiments of the present application.
[0197] In another possible implementation, the feature set includes a positioning feature set combination.
[0198] It can be understood that the feature set only includes the positioning feature set combination, that is, the feature set is only used to indicate the bandwidth aggregation capability of the positioning reference signal supported by the UE.
[0199] In this case, the UE can report the bandwidth aggregation capability of the positioning reference signal separately, which is not affected by the carrier aggregation capability of the data communication.
[0200] Next, the positioning feature set combination is described in detail.
[0201] Figure 7 A schematic diagram of a framework for positioning feature set combination is shown.
[0202] The positioning feature set combination (Feature Set Combination Pos SRS) includes at least one feature set corresponding to each frequency band, such as Figure 7 The feature sets per band-1 shown in FIG. 1 correspond to feature sets-1 (FeatureSet-1) and feature sets-2 (FeatureSet-2), each feature set including carrier aggregation features supported by the UE, for example, Figure 7 The feature set list per uplink CC is shown in FIG.
[0203] Figure 7 The frequency band feature sets, feature sets and corresponding feature parameters shown in are only exemplary. Figure 7 It may also include other frequency band feature sets, feature sets and corresponding feature parameters, which are not limited in the embodiments of the present application.
[0204] Among them, the carrier aggregation characteristics include characteristics related to positioning reference signals and characteristics related to communications.
[0205] Exemplarily, the characteristics related to the positioning reference signal may be the number of positioning reference signals, the subcarrier spacing of each positioning reference signal, the bandwidth of each positioning reference signal, etc., which is not limited in the embodiments of the present application.
[0206] Exemplarily, the communication-related features may be whether multiple input-multiple output (MIMO) multi-layer transmission is supported, the modulation order supported, etc., which is not limited in the embodiments of the present application.
[0207] It should be noted that the positioning feature set combination includes a feature set corresponding to each frequency band included in the first frequency band combination, for example, Figure 7 The number of frequency bands in Figure 4 The number of frequency bands in the positioning reference signal is the same. Each frequency band corresponds to at least one feature set. The specific parameters in different feature sets can be different, but there is a restriction here. The number of feature sets under each frequency band is the same; some parameters in each feature set must be reported by the UE, and some are optional (the UE may not report), but the parameters that the UE must report may not make sense for the positioning reference signal combination, so for these parameters that must be reported but are not related to the positioning reference signal, the UE can directly report 0 when reporting, or not support it.
[0208] For example, Figure 7 The NR downlink feature set (downlink set NR) in the feature set-1 shown in the figure is a parameter that the UE must report, but for the positioning feature set combination, the positioning feature set combination is for reporting positioning SRS-related capabilities and has nothing to do with downlink data.
[0209] It should be understood that for these parameters that the UE must report but are not related to the positioning reference signal, even if the UE reports 0 or does not support it, it still occupies signaling or bit overhead. Therefore, in order to further reduce signaling overhead, this application proposes to introduce a new field to specifically carry features related to the positioning reference signal.
[0210] In a possible implementation manner, the positioning feature set combination also includes a first feature set, and the first feature set is only used to carry features related to the positioning reference signal supported by the terminal device.
[0211] Figure 8 A schematic diagram of a framework of another positioning feature set combination is shown.
[0212] The positioning feature set combination includes a first feature set, such as Figure 8 The positioning feature set-1 (FeatureSetPosSRS) included in the frequency band positioning feature set-1 (FeatureSetsPerBand PosSRS-1) shown in the figure is only used to carry features related to the positioning reference signal, for example, uplink feature parameters (FeatureSetUplink).
[0213] Figure 8The frequency band positioning feature set, positioning feature set and corresponding positioning-related feature parameters shown in are only exemplary. Figure 8 It may also include other frequency band positioning feature sets, positioning feature sets and corresponding positioning-related feature parameters, which are not limited in the embodiments of the present application.
[0214] In a possible implementation manner, the information of the first frequency band combination is further used to indicate the maximum aggregated number and / or the maximum aggregated bandwidth of the positioning reference signals supported by the UE.
[0215] Exemplarily, the first frequency band combination also includes a first field, and the first field is used to indicate the maximum aggregated number and / or the maximum aggregated bandwidth of positioning reference signals supported by the UE.
[0216] For example, in Figure 4 A field is added to the band list (bandList) under each band combination in the positioning bandwidth aggregation capability value (ca-BandwidthClassPosSRS).
[0217] The value of this field can reuse the reference value in data communication, but its meaning is the number of positioning reference signals supported and the maximum aggregation bandwidth. For example, a maximum of 3 positioning reference signals are supported, and the maximum bandwidth does not exceed 200 MHz.
[0218] It should be understood that the UE can flexibly report which carriers it wants to support carrier aggregation for positioning, the number of carriers it wants to aggregate, and the bandwidth size of the SRS in each carrier participating in the aggregation; without being restricted by the carrier aggregation capability value of the communication.
[0219] For example, the carrier aggregation capability reported by communication is 50 MHz for CC1 and CC2 respectively; but the bandwidth aggregation capability that can be reported by positioning can be 40 MHz and 60 MHz for CC1 and CC2 respectively.
[0220] This increases the flexibility of the base station in configuring the positioning reference signal for carrier aggregation.
[0221] It should be noted that the aggregated number and / or aggregated bandwidth of the positioning reference signals in the positioning feature set combination is less than or equal to the maximum aggregated number and / or maximum aggregated bandwidth of the positioning reference signals supported by the UE indicated by the first field.
[0222] S320, the terminal device receives first configuration information from the network device.
[0223] The network device receives the information of the first frequency band combination, determines the configuration information (first configuration information) of the positioning reference signal according to the information of the first frequency band combination, and sends the first configuration information to the UE.
[0224] The first configuration information is used by the UE to send the positioning reference signal.
[0225] According to the technical solution, for the information of the first frequency band combination, a positioning feature set combination is introduced on the basis of the data communication feature set combination, thereby avoiding reporting the frequency band combination list twice, thereby saving the overhead caused by repeated reporting of the frequency band combination; further, a positioning feature set (an example of the first feature set) is introduced, which only contains uplink positioning-related capabilities, and there is no need to report features unrelated to positioning, thereby reducing the signaling overhead when UE capabilities are reported, and realizing the decoupling of positioning bandwidth aggregation and data carrier aggregation capabilities; in addition, the present application can also indicate the maximum aggregation number and / or the maximum aggregation bandwidth of positioning reference signals supported by the UE in the first frequency band combination, without being limited to the carrier aggregation capability value of the communication, thereby realizing flexible positioning bandwidth aggregation capability reporting.
[0226] Fig. 9 It is a schematic flowchart of another information reporting method 900 provided in an embodiment of the present application.
[0227] It should be understood that in the embodiment of the present application, the terminal device sends information of the first frequency band combination to the network device, and the network device sends first configuration information to the terminal device according to the information of the first frequency band combination, for instructing the terminal device to send a positioning reference signal. The specific process is similar to method 300 and will not be repeated here.
[0228] The difference from method 300 is that, in the present application, the information of the first frequency band combination does not include a positioning feature set combination.
[0229] In this embodiment, the information of the first frequency band combination is used to indicate the bandwidth aggregation capability of the positioning reference signal supported by the UE.
[0230] In one possible implementation, the first frequency band combination includes at least one frequency band, and the at least one frequency band corresponds to at least one frequency band parameter list. Each frequency band parameter list in the at least one frequency band parameter list includes a second field, and the second field is used to indicate the bandwidth aggregation capability of the positioning reference signal supported by the terminal device.
[0231] Fig. 9 Compared to Figure 2 The UE reporting method shown is Figure 2 Based on (a), a new field is added to the frequency band parameter list under the frequency band combination to carry the bandwidth aggregation capability information of the positioning reference signal.
[0232] like Fig. 9As shown, a new field, such as posSRS-BandwidthAggregation, is added to each band parameter list in band combination-1 (e.g., BandParameters-1). If the UE reports this field, it means that the UE can support the bandwidth aggregation capability of the positioning reference signal without being limited by the carrier aggregation capability of the data.
[0233] In a possible implementation manner, the second field is further used to indicate the maximum aggregation number and / or the maximum aggregation bandwidth of positioning reference signals supported by the UE.
[0234] Specifically, the UE can flexibly report the carrier aggregation on which it wants to support positioning, the number of carriers to be aggregated, and the bandwidth size of the SRS in each carrier participating in the aggregation, without being limited by the carrier aggregation capability value of the communication. For details, please refer to the first field in method 300, which will not be repeated here.
[0235] In a possible implementation manner, the second field is also used to indicate characteristics of the positioning reference signal supported by the UE.
[0236] Exemplarily, the characteristics of the positioning reference signal include parameters such as the number of positioning reference signals that support aggregation, the bandwidth of each positioning reference signal, and the subcarrier spacing of the positioning reference signal, which are not limited in the embodiments of the present application.
[0237] In another possible implementation manner, the second field may include two subfields, one of which is used to report the maximum number of aggregations that can be aggregated and / or the maximum aggregation bandwidth when the positioning reference signal is aggregated for bandwidth aggregation. The field may be Fig. 9 The positioning reference signal bandwidth value posSRS-BandwidthClass shown in the figure; another field is used to report the characteristics of the positioning reference signal supported by the UE, for example, it can be Fig. 9 The uplink feature set featureSetUplink is shown in FIG.
[0238] Fig. 9 The frequency band combinations, frequency band lists, frequency band parameter lists, and corresponding characteristic parameters shown in the figure are only exemplary. Fig. 9 It may also include a frequency band combination, a frequency band list, a frequency band parameter list and corresponding characteristic parameters, which is not limited in the embodiments of the present application.
[0239] According to the technical solution, the bandwidth aggregation capability of the positioning reference signal is directly introduced at the band parameter level, and the parameters of the bandwidth aggregation of the positioning reference signal are added, such as bandwidthclass, supportedSubcarrierSpacingUL, and supportedBandwidthUL. The UE only needs to report the positioning bandwidth aggregation parameters once in each frequency band, avoiding reporting the carrier aggregation capability of data communication and the bandwidth aggregation capability of positioning separately by reporting the frequency band combination list twice, thereby further reducing the signaling overhead.
[0240] Fig.10 It is a schematic flowchart of another information reporting method 1000 provided in an embodiment of the present application.
[0241] It should be understood that in the embodiment of the present application, the terminal device sends information of the first frequency band combination to the network device, and the network device sends first configuration information to the terminal device according to the information of the first frequency band combination, for instructing the terminal device to send a positioning reference signal. The specific process is similar to method 300 and will not be repeated here.
[0242] The difference from method 300 is that, in the present application, the information of the first frequency band combination does not include a positioning feature set combination.
[0243] In this embodiment, the information of the first frequency band combination is used to indicate whether the UE supports only the bandwidth aggregation capability of the positioning reference signal on each carrier.
[0244] Specifically, the information of the first frequency band combination indicates that when the UE only supports the bandwidth aggregation capability of the positioning reference signal on each carrier, the UE does not support the carrier aggregation capability of communication on each frequency band.
[0245] In one possible implementation, the first frequency band combination includes at least one frequency band, the at least one frequency band corresponds to at least one feature set, each feature set in the at least one feature set includes capability information of multiple carriers, and the capability information of some or all of the multiple carriers includes a third field, and the third field is used to indicate whether the terminal device only supports the bandwidth aggregation capability of the positioning reference signal in each carrier.
[0246] In this embodiment, a third field may be added to the capability list of each carrier to indicate whether the current carrier only supports transmission bandwidth aggregation of positioning reference signals.
[0247] Exemplarily, when the third field is 1, it is used to indicate that the current carrier only supports bandwidth aggregation of positioning reference signals. In other words, in the capability information of multiple carriers corresponding to each feature set, the carrier with the third field only supports the bandwidth aggregation capability of positioning reference signals, and does not support the carrier aggregation capability of data communication. In other words, if there is no third field in the capability information of the carrier, the carrier supports the bandwidth aggregation capability of positioning reference signals and also supports the carrier aggregation capability of data communication.
[0248] Exemplarily, when the third field is 0, it is used to indicate that the current carrier not only supports bandwidth aggregation of positioning reference signals. In other words, in the capability information of multiple carriers corresponding to each feature set, the carrier with the third field not only supports the bandwidth aggregation capability of positioning reference signals, but also supports the carrier aggregation capability of data communication. In other words, if there is no third field in the capability information of the carrier, the carrier only supports the bandwidth aggregation capability of positioning reference signals, and does not support the carrier aggregation capability of data communication.
[0249] In one possible implementation, when the capability information of each carrier in the feature set includes the third field, when the third field indicates that the UE only supports the bandwidth aggregation capability of the positioning reference signal on each of the carriers, the UE supports the bandwidth aggregation of the positioning reference signal on all the carriers; when the third field indicates that the terminal device does not only support the bandwidth aggregation capability of the positioning reference signal on each of the carriers, the terminal device supports carrier aggregation for data communication on all the carriers.
[0250] In another possible implementation, the capability information of all carriers in the feature set includes a first part of carriers and a second part of carriers, and the capability information of the first part of carriers includes a third field. When the third field indicates that the UE only supports the bandwidth aggregation capability of the positioning reference signal on the first part of carriers, the UE supports the first part of carriers and the second part of carriers for bandwidth aggregation of the positioning reference signal; when the third field indicates that the UE does not only support the bandwidth aggregation capability of the positioning reference signal on the first part of carriers, the terminal device supports carrier aggregation of the first part of carriers and the second part of carriers for data communication.
[0251] like Fig.10 As shown, one uplink feature set (fetureSetUplink-1) includes capability information of multiple carriers, such as feature set list-1 (fetureSetListPerUplinkCC-1) for each uplink carrier and feature set list-2 (fetureSetListPerUplinkCC-2) for each uplink carrier. The third field in the capability information of each carrier can be used to indicate whether the carrier supports the bandwidth aggregation capability of the positioning reference signal.
[0252] For example, a new field is added to fetureSetListPerUplinkCC-1, such as SRS-CA-only (only supports bandwidth aggregation of positioning reference signals). If this field appears, it means that the current CC-1 is only used for positioning bandwidth aggregation and cannot be used for data carrier aggregation; if this field does not appear in a CC, it means that the CC can be used for both carrier aggregation for data communication and SRS bandwidth aggregation for positioning.
[0253] Fig.10 The feature set, carrier capability information, and corresponding feature parameters shown in the figure are only exemplary. Fig.10 It may also include other feature sets, carrier capability information, and corresponding feature parameters, which are not limited in the embodiments of the present application.
[0254] According to the technical solution, the information of the first frequency band combination is used to indicate whether the UE supports only the bandwidth aggregation capability of the positioning reference signal in each carrier. Specifically, a field (such as SRSPos-only) is added to the capability information of the corresponding multiple carriers in each feature set (for example, in the original FeatureSetUplinkPerCC), avoiding the need to report the carrier aggregation capability of data communication and the bandwidth aggregation capability of positioning separately through two frequency band combination lists, thereby effectively reducing the signaling overhead. In addition, this method makes relatively small changes to the protocol, so the implementation complexity is lower.
