Description

Technical Field

[0001] This invention relates to the field of wireless communication systems or networks, and more particularly, to the configuration of transmitting or receiving beam directions in such networks. Background Technology

[0002] Figures 1(a) and 1(b) are schematic diagrams of an example of a terrestrial wireless network 100. As shown in Figure 1(a), the terrestrial wireless network includes a core network 102 and one or more radio access networks RAN1, RAN2, ... RAN N (RAN = Radio Access Network). Figure 1(b) shows the Radio Access Network (RAN). n The example is a schematic representation that the radio access network may include one or more base stations gNB1 to gNB5 (gNB = Next Generation Node B), each base station serving a specific area around the base station schematically represented by corresponding cells 1061 to 1065. Base stations are provided to serve users within the cell. One or more base stations may serve users in licensed and / or unlicensed frequency bands. The term base station (BS) refers to gNB in ​​5G networks, eNB in ​​UMTS / LTE / LTE-A / LTE-APro, or BS in other mobile communication standards. Users may be fixed or mobile devices. Mobile or fixed IoT (Internet of Things) devices connected to base stations or users may also access the wireless communication system. Mobile devices or IoT devices may include physical devices, ground-based vehicles (such as robots or cars), air vehicles (such as manned or unmanned aircraft UAVs, the latter also known as drones), buildings and other items or devices in which electronic devices, software, sensors, actuators, etc., are embedded, and network connections enabling these devices to collect and exchange data across existing network infrastructure. Figure 1(b) shows an exemplary view of five cells; however, RAN n It can include more or fewer such cells, and RAN nAlternatively, only one base station may be included. Figure 1(b) shows two users, UE1 and UE2 (UE = User Equipment), also referred to as User Equipment UE, which are in cell 1062 and served by base station gNB2. Another user, UE3, is shown in cell 1064 served by base station gNB4. Arrows 1081, 1082, and 1083 schematically represent uplink / downlink connections used for transmitting data from users UE1, UE2, and UE3 to base stations gNB2 and gNB4, or for transmitting data from base stations gNB2 and gNB4 to users UE1, UE2, and UE3. This can be implemented on licensed or unlicensed frequency bands. Furthermore, Figure 1(b) shows two IoT devices, 1101 and 1102, in cell 1064, which can be fixed or mobile devices. IoT device 1101 accesses the wireless communication system via base station gNB4 to receive and transmit data, as schematically indicated by arrow 1121. As schematically indicated by arrow 1122, IoT device 1102 accesses the wireless communication system via user UE3. Each base station gNB1 to gNB5 can be connected to the core network 102, for example, via the S1 interface and via backhaul links 1141 to 1145, which are schematically represented in Figure 1(b) by arrows pointing to the “core”. The core network 102 can be connected to one or more external networks. External networks can be the Internet or private networks, such as intranets or any other type of campus network, such as dedicated WiFi or 4G or 5G mobile communication systems. Furthermore, some or all of the base stations gNB1 to gNB5 can be connected to each other, for example, via the S1 or X2 interface or XN interface in NR (New Radio) via backhaul links 1161 to 1165, which are schematically represented in Figure 1(b) by arrows pointing to the “gNB”. Sidelink channels allow direct communication between UEs, also known as device-to-device (D2D) communication. The sidelink interface in 3GPP (3G Partnership Program) is designated PC5 (Proximity-Based Communication 5).

[0003] For data transmission, a physical resource grid can be used. A physical resource grid can include a collection of resource elements to which various physical channels and physical signals are mapped. For example, physical channels can include the Physical Downlink Shared Channel (PDSCH), the Physical Uplink Shared Channel (PUSCH), and the Physical Sidelink Shared Channel (PSSCH), carrying user-specific data (also known as downlink, uplink, and sidelink payload data); the Physical Broadcast Channel (PBCH), carrying, for example, a Master Information Block (MIB), and one or more System Information Blocks (SIBs); one or more Sidelink Information Blocks (SLIBs); and, if supported, the Physical Downlink Control Channel (PDCCH), the Physical Uplink Control Channel (PUCCH), and the Physical Sidelink Control Channel (PSSCH), carrying, for example, downlink control information (DCI), uplink control information (UCI), and sidelink control information (SCI); and the Physical Sidelink Feedback Channel (PSFCH), carrying PC5 feedback responses. Note that the sidelink interface can support two levels of SCI (voice call item). This refers to a first control area containing some parts of SCI, and optionally, a second control area containing a second part of control information.

[0004] For the uplink, physical channels may also include a Physical Random Access Channel (PRACH, Packet Random Access Channel) or a RACH (Random Access Channel), which the UE uses to access the network once it is synchronized and has acquired the MIB and SIB. Physical signals may include reference signals or symbolic synchronization signals (RS). The resource grid may include frames or radio frames that have a specific duration in the time domain and a given bandwidth in the frequency domain. The frame may have a number of subframes of a predetermined length, such as 1 millisecond. Depending on the length of the cyclic prefix (CP), each subframe may include one or more time slots of 12 or 14 OFDM symbols (OFDM = Orthogonal Frequency Division Multiplexing). For example, a frame may also include a smaller number of OFDM symbols when utilizing a shortened transmission time interval (sTTI, time slot or sub-slot transmission time interval) or a mini-slot-based / non-slot-based frame structure that includes only a few OFDM symbols.

[0005] The wireless communication system can be any single-tone or multi-carrier system using frequency division multiplexing, such as Orthogonal Frequency Division Multiplexing (OFDM) or Orthogonal Frequency Division Multiple Access (OFDMA), or any other IFFT-based signal (IFFT = Inverse Fast Fourier Transform) with or without CP, such as DFT-s-OFDM (DFT = Discrete Fourier Transform). Other waveforms can be used, such as non-orthogonal waveforms for multiple access, such as Filter Bank Multicarrier (FBMC), Universal Frequency Division Multiplexing (GFDM), or Universal Filtered Multicarrier (UFMC). The wireless communication system can operate, for example, according to the LTE-Advanced Pro standard, or the 5G or NR New Radio standard, or the NR-U New Radio License-Free standard.

[0006] The wireless networks or communication systems depicted in Figures 1(a) and 1(b) can be heterogeneous networks with different overlapping networks, such as macrocell networks, where each macrocell includes macro base stations, such as base stations gNB1 to gNB5, and small cell base station networks, such as femtocells or picocells, not shown in Figures 1(a) and 1(b). In addition to the terrestrial wireless networks described above, there are also non-terrestrial wireless communication networks (NTNs), including satellite transceivers and / or airborne transceivers such as unmanned aerial vehicle (UAV) systems. Non-terrestrial wireless communication networks or systems can operate in a similar manner to the terrestrial systems described above with reference to Figures 1(a) and 1(b), for example, according to the LTE-Advanced Pro standard or the new 5G or NR radio standards.

[0007] In mobile communication networks, such as those described above with reference to Figures 1(a) and 1(b), such as LTE or 5G / NR networks, there may be UEs that communicate directly with each other via one or more sidelink SL channels, for example, using PC5 / PC3 interfaces or WiFi direct. UEs communicating directly with each other via sidelinks can include vehicle-to-vehicle (V2V) communication with other vehicles, and vehicle-to-X (V2X) communication with other entities in the wireless communication network, such as roadside units (RSUs) or roadside entities like traffic lights, traffic signs, or pedestrians. Depending on the specific network configuration, an RSU may function as a BS or UE. Other UEs may not be vehicle-related and may include any of the aforementioned devices. Such devices may also communicate directly with each other using S1 channels, i.e., D2D communication.

[0008] In the wireless communication networks depicted in Figures 1(a) and 1(b), it may be desirable to locate the UE with a certain accuracy, for example, to determine the UE's location within the cell. Several positioning methods are known, such as satellite-based positioning methods, such as autonomous and assisted global navigation satellite systems (A-GNSS, such as GPS), mobile radio cellular positioning methods (e.g., observed time difference of arrival (OTDOA) and enhanced cell ID (E-CID)), or combinations thereof.

[0009] Note that the information in the above sections is only used to enhance the understanding of the background of the present invention, and therefore may contain information that does not constitute prior art known to those skilled in the art.

[0010] Fraunhofer IIS, Fraunhofer HHI: “NR beam management supporting multi-gNB measurements for positioning”, RAN WG1, Spokane, USA; 20181112-20181116, November 11, 2018 (2018-11-11), XP051555639, discloses how to implement the measurement of a reference signal for positioning, which is transmitted (or received) in a height-oriented beam from different locations (or at different locations).

[0057] Embodiments of the invention will now be described in more detail with reference to the accompanying drawings, in which the same or similar elements have the same reference numerals.

[0058] For DL-PRS (Downlink Positioning Reference Signal), the TRP (Transmitter Receiver Point) may need to configure multiple PRS (Positioning Reference Signal) resources to provide coverage within a specific area. This becomes relevant to the second case when beam steering information is used to enable SP-PRS (Semi-Persistent Positioning Reference Signal) or A-PRS (Aperiodic Positioning Reference Signal) procedures.

[0059] For aperiodic and / or semi-persistent (AP, SP) PRS, M-TRP (Multiple TRP) cannot be enabled based on the Rel-16 procedure. Furthermore, for UL-SRS (Uplink Sound Reference Signal), the TRP may miss some SRS (Sound Reference Signal) transmissions because the start time of measurement at the non-serving cell is unknown.

[0060] TRP provides no information or measurement reports to select the direction of sending or receiving the reference signal.

[0061] In DL (downlink): Without this information, TRP cannot perform on-demand or UE-specific PRS (i.e., not a pre-configured multi-TRP beam configuration).

[0062] In UL (uplink): If the TRP does not have a direction indication in the direction of the UL reference signal (especially in FR2; frequency range 2), it introduces additional complexity to the TRP.

[0063] The Location Management Function (LMF) provides the TRP with information about the direction in which the TRP is expected to receive UL-SRS or transmit DL-PRS. The focus is on signaling and procedures, including the type of information provided. This information reduces the complexity and latency of the TRP, especially for TRPs that do not directly communicate with the target UE whose location is being determined (i.e., no UE RSRP report is available; RSRP = Reference Signal Received Power).

[0064] Figure 2The diagram illustrates that in the downlink, the TRP receives information about the direction of one or more DL-PRS resources, and in the uplink, the TRP is instructed on the Rx beam to receive one or more UL-SRS signals from the UE.

[0065] Figure 3 This diagram illustrates a wireless location communication system, and more specifically, an example of a location wireless network architecture. The wireless communication system shown can be any single-tone or multi-carrier system using frequency division multiplexing, such as Orthogonal Frequency Division Multiplexing (OFDM) or Orthogonal Frequency Division Multiple Access (OFDMA), or any other IFFT-based signal with or without CP, such as DFT-s-OFDM. Other waveforms can be used, such as non-orthogonal waveforms for multiple access, such as Filter Bank Multicarrier (FBMC), General Frequency Division Multiplexing (GFDM), or General Filtered Multicarrier (UFMC). The wireless communication system can operate, for example, according to the LTE-Advanced Pro standard, or the 5G or NR New Radio standard, or the NR-U New Radio License-Free standard.

[0066] The wireless network or communication system depicted in the figure can be a heterogeneous network with different overlapping networks, such as a macrocell network, where each macrocell includes macro base stations, such as base stations BS1 to BS4, and a small cell base station network not shown in the figure, such as femtocells or picocells. In addition to the terrestrial wireless networks described above, there are also non-terrestrial wireless communication networks (NTNs), including satellite transceivers and / or airborne transceivers such as unmanned aerial vehicle (UAV) systems. Non-terrestrial wireless communication networks or systems can operate in a similar manner to the terrestrial systems described above with reference to the accompanying figures, for example, according to the LTE-Advanced Pro standard or the new 5G or NR radio standards.

[0067] The base station can wirelessly communicate and exchange messages with one or more UEs (104, 108, 109) and / or one or more reference devices (104). The base station can directly communicate and exchange information with other base stations (106, 110), which may be from the same technology and / or the same or different generations or even different technologies. The target UE and / or reference device can perform radio signaling (112 to 116) for positioning or synchronization purposes. A BS may include distributed units connected sequentially to the corresponding central unit or BS via an F1 interface (106) or through a non-standard interface. Two central BSs may also be connected via an XN / X2 interface or through a non-standard interface.

[0068] In mobile communication networks, such as those described above with reference to the accompanying figures, such as LTE or 5G / NR networks, there may be UEs that communicate directly with each other via one or more sidelink S1 channels, for example using PC5 / PC3 interfaces or WiFi direct (107). UEs communicating directly with each other via sidelinks can include vehicle-to-vehicle (V2V) communication with other vehicles, and vehicle-to-everything (V2X) communication with other entities in the wireless communication network, such as roadside units (RSUs) or roadside entities like traffic lights, traffic signs, or pedestrians. Depending on the specific network configuration, an RSU may function as a BS or UE. Other UEs may not be vehicle-related UEs and may include any of the aforementioned devices. Such devices may also communicate directly with each other using S1 channels, i.e., D2D communication.

[0069] Calculating the UE's location may involve network entities and interfaces between the UE (101, 103) and other network RAN ​​entities or similar entities (102, 105). Network entities can be part of the core network, including Location Management Functions (LMFs) and Access and Mobility Management Functions (AMFs), which communicate using the Network Layer Signaling Protocol (NL). Network entities can also include location servers that communicate with other entities and devices in the network via control or user plane interfaces.

[0070] In the wireless communication network depicted in the attached figure, it may be desirable to locate the UE with a certain accuracy, for example, to determine the UE's location within the cell. Several positioning methods are known, such as satellite-based positioning methods, such as autonomous and assisted global navigation satellite systems (A-GNSS, such as GPS), mobile radio cellular positioning methods (e.g., observed time difference of arrival (OTDOA) and enhanced cell ID (E-CID)), or combinations thereof.

[0071] Note that the information in the above sections is only used to enhance the understanding of the background of the present invention, and therefore may contain information that does not constitute prior art known to those skilled in the art.

[0072] Figure 9 A device 210 for transmitting and receiving data in a wireless communication system according to one embodiment is shown.

[0073] Device 210 is configured to receive a first message and / or a second message from another network entity.

[0074] Furthermore, the device 210 is configured to determine one or more transmit spatial filters and / or one or more receive spatial filters and / or one or more beam directions; wherein the one or more transmit spatial filters and / or one or more receive spatial filters are the same as at least one initial spatial filter, or are derived by the device 210 from at least one initial spatial filter. The one or more beam directions are the same as at least one initial beam direction, or are derived by the device 210 from at least one initial beam direction.

[0075] Furthermore, the device 210 is configured to apply one or more transmit space filters and / or one or more receive space filters and / or one or more beam directions on one or more downlink resources and / or one or more uplink resources.

[0076] According to another embodiment, device 210 may be, for example, a base station.

[0077] According to one embodiment, support for beam indication of uplink measurements may be provided, for example.

[0078] In one embodiment, the device may be, for example, a base station (gNB) and may provide gNB indication, for example, uplink SRS for uplink positioning assistance data.

[0079] In one embodiment, device 210 may be, for example, a user equipment (UE). Alternatively, in one embodiment, device 210 may implement, for example, a location management function (LMF).

[0080] For example, according to one embodiment, an indication for DL-PRS for on-demand PRS auxiliary data can be provided. For example, this indication can be sent from the LMF to the gNB, or it can be sent from the UE to the LMF, which can then forward the indication to the gNB.

[0081] For example, according to one embodiment, downlink PRS parameters (e.g., DL PRS QCL information) can be used, for example, for UE-initiated and LMF-initiated on-demand downlink PRS requests (QCL: Quasi-co-address).

[0082] In one embodiment, apparatus 210 may be, for example, a user equipment (UE), and the UE may, for example, receive an indication of uplink SRS for downlink positioning assistance data.

[0083] According to one embodiment, device 210 (e.g., UE) may receive direction information (e.g., for AoD) from LMF, which is derived based on a coarse position estimate for DLAoD assistance. This may, for example, help reduce the search space at device 210 (e.g., at the UE).

[0084] For example, for DL-AoD of two UEs (e.g., UE-A and UE-B), and regarding support for AoD measurements with expected uncertainty windows, an indication of the range of expected angle values ​​and (expected azimuth and zenith angle values) uncertainty can be signaled to device 210 (e.g., UE) by the LMF, and / or the type of expected angle and uncertainty can be requested by device 210 (e.g., UE).

[0085] For example, an indication of the expected DL-AoD / ZoD value and the range of uncertainty (of the expected DL-AoD / ZoD value) can be signaled to device 210 (e.g., UE) by the LMF, for example.

[0086] And / or, for example, an indication of the expected DL-AoA / ZoA value and the range of uncertainty of the expected DL-AoA / ZoA value can be signaled to device 210 (e.g., UE) by the LMF.

[0087] According to one embodiment, device 210 may be configured, for example, to receive a first message from another network entity in a wireless network, the first message indicating a measurement request, an information request, or a location activation request. Device 210 may be configured, for example, to receive a second message from another network entity, the second message including an indication of at least one initial spatial filter or an indication of at least one initial beam direction for transmitting one or more downlink resources and / or receiving one or more uplink resources.

[0224] Definitions are provided below, and specific embodiments of the invention are described.

[0225] First, provide the definition of network entities / nodes.

[0226] Network nodes can be LMFs (Location Management Functions) or LSs (Location Servers) located in the core network, or local LMFs in radio access networks that provide beaming information to BSs (Browsing Sites) in the network. LMFs can manage support for different location services for the target UE, including UE positioning and the delivery of auxiliary data to the UE. LMFs can interact with the serving BS of the target UE to obtain UE location measurements, including uplink measurements performed by the BS.

[0227] Network nodes can interact with a target UE to deliver auxiliary data when requesting location-specific services, or to obtain location estimates upon request. Network nodes can interact with multiple BSs to provide auxiliary data information for broadcasting.

[0228] For the location of a target UE, network nodes can determine the location method to use based on factors including LCS client type, required QoS, UE location capabilities, and BS location capabilities. The location method can produce a location estimate using a UE-based location method and / or location measurements using UE-assisted and network-based location methods. Network nodes can combine all received results and determine a single location estimate for the target UE (hybrid location). Additional information, such as the accuracy of the location estimate and velocity, can also be determined.

[0229] The definition of BS is provided below.

[0230] A Base Station (BS) is a network element in a Radio Access Network (RAN) or Next Generation Radio Access Network (NG-RAN) that provides measurement information for a target UE and transmits this information to network nodes. To support RAT-related positioning, the BS can measure the radio signals of the target UE or reference device and provide the measurement results for location estimation. A BS can serve several BSs or TRPs, including, for example, remote radio head ends, receive-only points (RPs), and transmit-only points (TPs). The BS can broadcast auxiliary data information received from the Local Area Function (LMF) in positioning system information messages.

[0231] In some scenarios, a set of TRPs is not steady-state (or non-steady-state). At the core network level, or for the TRPs themselves, or for the communication or location estimation entities, the location or trajectory of a non-steady-state TRP may be known.

[0232] In one example, the non-steady-state TRP is a non-terrestrial network (NTN) or an aerial network (drone) or a vehicle or mobile device, where the location entity (UE-based in UE mode and network node-based in UE-assisted or network mode) knows the location of the transmit antenna corresponding to the non-steady-state TRP at the time of transmission or reception.

[0233] In the following text, we consider the downlink reference signal DL-RS.

[0234] The downlink reference signal (DL-RS) described in this article is a reference signal transmitted from a device that acts as a base station, reference device, or positioning TRP / TP, etc.

[0235] DL-RS can be used to implement downlink positioning measurements using DL methods or UL and DL methods, such as TDOA, RTT, multi-RTT, or DL-AoD. Those skilled in the art may refer to DL-RS as DL-PRS, LTE PRS, SL-PRS, or any downlink or sidelink reference signal used for positioning purposes. DL-RS may correspond to a specific positioning reference signal (PRS) or communication reference signal used for the purpose of positioning such an SSB or CSI-RS.

[0236] A DL-RS resource set is defined as a collection of one or more DL-RS resources, each with a DL-RS resource ID. Optionally, DL-RS resources within a DL-RS resource set can be associated with the same TRP or frequency layer. Each DL-RS resource ID within a DL-RS resource set can be associated with a specific spatial filter. A TRP can be configured with multiple DL-RS resource sets. A DL-RS resource set consists of one or more DL-RS resources and has several parameters set. These parameters can include time-domain behavior or periodicity and slot offset. In the case of DL-PRS, the information element Periodicity-and-ResourceSetSlotOffset-r16 defines the DL-PRS resource period for each DL-PRS resource set. All DL-PRS resources within a DL-RS resource set are configured with the same DL-PRS resource period. Semi-persistent scheduling allocates DL resources at a specific period over defined intervals. For aperiodic DL-PRS, no periodicity value is configured.

[0237] The BS or TRP can transmit multiple DL-RS resource sets, each containing one or more DL-RS resources. DL-RS resource sets can be associated with beam sets (where each DL-RS resource corresponds to or is associated with a beam), which are transmitted at a configured period within a configured offset. Some sets will be configured to have a given period.

[0238] A DL-RS positioning frequency layer is defined as a set of DL-RS resources that have common parameters and can be configured by a higher parameter positioning frequency layer.

[0239] The DL-RS resources and resource set configuration are provided to the UE from the LMF or possibly from the serving cell via RRC or MAC-CE (Media Access Control-Control Element) messages or via DCI (Downlink Control Information) through a higher-layer interface such as LPP (LTE Location Protocol). The UE performs measurements on the configured DL-RS resources.

[0240] The UE or reference device can be configured for measurements of one or more DL-RS or SL-RS resources. The RS can be a DL-PRS or SL-PRS resource. This configuration can be provided to the UE via a higher-level configuration message, which includes auxiliary information about the DL-RS resource transmitted from one or more BSs or TRPs. The auxiliary information for the DL-RS or SL-RS may include one or more of the following: resource set, resource set ID, periodicity, resource repetition factor, resource slot, SFN0 offset, resource set slot offset, resource ID, sequence ID, CombSizeN, ReOffset, resource slot offset, resource symbol offset, digital symbol, QCL information, subcarrier spacing, cyclic prefix, resource bandwidth, StartPRBDL-RS-PointA, RstdReferenceInfo, RstdMeasurementInfoRequest, UE-Rx-Tx-MeasurementInfoRequest, expected RSTD, RSTD uncertainty, and silent mode.

[0241] A configuration entity, acting as a network entity or serving base station, can provide or update DL-RS or SL-RS measurement configurations to a UE or reference device. In one example, if the configuration entity is an LMF, the configuration can be indicated as an IE (Information Element) on a higher-layer interface such as an LPP. If the configuration entity is a base station, the configuration can be indicated via RRC, MAC-CE, or DCI. If the configuration entity is a UE or reference device, the configuration can be indicated via the PC5 (Side Link) interface.

[0242] Network entities can configure a BS or reference device for transport configurations on one or more DL-PRS or SL-PRS resources. The configuration entity provides the UE with higher-layer configuration messages, which include auxiliary information about DL-PRS resources received from one or more TRPs. The configuration entity provides or updates one or more DL-PRS configurations to the TRPs, which are represented as IEs (Information Elements) on higher-layer interfaces, such as NRPPa (NR Positioning Protocol A) for the configuration entity being an LMF, or one of Xn, F1, or X2 for the configuration entity being a base station, or PC5 (Side Link) interface for the configuration entity being a UE.

[0243] In the following text, the UL RS uplink reference signal is considered.

[0244] The uplink reference signal (UL-RS) described herein is a reference signal transmitted from a device acting as a UE or reference device, etc. Those skilled in the art may refer to the UL-RS as UL-PRS, SRS for positioning, SL-PRS, or any uplink or sidelink reference signal for positioning purposes.

[0245] The UL reference signal is transmitted by the UE or a reference device and can be a dedicated positioning reference signal, such as a UL-PRS or SRS used for or configured for positioning, or a communication reference signal used for positioning purposes (e.g., an SRS used for or configured for MIMO). The configuration of the UL-PRS or SRS resource set and resources is determined by a higher layer configuration from the LMF or possibly from the serving cell via RRC, MAC-CE, or DCI messages through a higher interface such as LPP.

[0246] An SRS resource set is defined as a collection of one or more SRS resources, each of which has an SRS resource ID, and may include one or more of the following:

[0247] • SRS configuration: A list of resources and resource sets to add or remove.

[0248] • The maximum number (N) of each SRS resource group used for positioning.

[0249] The maximum number of SRS resource sets supported for location services is a UE capability, with configurability of up to N resource sets per bandwidth portion (BWP).

[0250] • A list of SRS resources within the collection.

[0251] • Trigger type of resources within the collection (periodic, SP: semi-persistent, aperiodic),

[0252] • SRS power control parameters, including α and P0 values, and a reference signal used to determine path loss.

[0253] Figure 4 The document provides an IE example of SRS resources. Figure 4 The SRS resource configuration is shown.

[0254] A configuration entity (serving gNB or LMF) configures the UE for transmissions of one or more UL-PRS, SRS, or SL-PRS resources. The configuration entity provides the UE with higher-layer configuration messages, which include auxiliary information about the UL-PRS or SRS resources received from one or more TRPs. The auxiliary information for the UL-PRS or SRS may include one or more of the following: SRS-ResourceSetId, SRS-ResourceId, UL-BWP ID, Serving Cell ID, Cell PCI, ssbFrequencyhalfFrameIndex, SSB periodicity, SSB subcarrier spacing, SFN-SSB offset, SMTC, SSB index, SFN0 offset, ss-PBCH-BlockPower ID, DL-PRS-ResourceSetID, DL-PRS-ResourceId, NZP-CSIRS-ResourceID, and Serving Cell ID. The configuration entity can be an entity in the core network, a base station, or a UE.

[0255] The configuration entity provides or updates one or more UL-PRS configurations to the UE. The LMF indicates the configuration as an IE (Information Element) on a higher-layer interface such as LPP. The base station indicates the configuration via one of the following: RRC, MAC-CE, or DCI. Configuration can also be indicated via PC5 (side link) from a second UE.

[0256] The general definition of SL PRS resources is provided below.

[0257] Side link (SL) reference signals are transmitted by the UE, reference equipment, or side link devices such as roadside units (RSUs), and can be dedicated positioning reference signals such as SL-PRS or SRS for positioning purposes, or communication or synchronization reference signals such as SPSS or SSSS for positioning purposes.

[0258] The general definition of a spatial filter is provided below.

[0259] A spatial domain filter, or spatial filter, refers to precoding or filtering applied at the antenna port of a communication device. Precoding or filtering can be performed or implemented on the transmitted or received signal in the analog or digital domain, or a combination thereof (hybrid). This results in the device forming spatially selective or directional transmission or reception, referred to as a transmit beam or receive beam, respectively. The terms "spatially selective" or "spatially directional" mean that the beam formed by the spatial filter or spatial domain filter is able to transmit or receive signals with higher gain in certain spatial directions. A transmit / transmit / Tx beam indicates spatially selective / directional transmission obtained from a spatial filter. A receive / receive / Rx beam indicates spatially selective / directional reception obtained from a spatial filter.

[0260] The general definition of QCL relations is provided below.

[0261] If the properties of the channel transmitting symbols on one antenna port can be inferred from the properties of the channel transmitting symbols on the other antenna port, then the two antenna ports are said to be quasi-co-located (QCL).

[0262] In NR, the spatial parameters of QCL describe the spatial channel properties of the RS antenna port observed at the receiver. These parameters can include one or more of the following: angle of arrival (AoA), main AoA, average AoA, power angular spectrum (PAS) of AoA, departure angle (AoD), average AoD, PAS of AoD, transmit / receive channel correlation, transmit / receive beamforming, spatial channel correlation, etc.

[0263] In NR, the spatial Rx parameter of QCL describes the spatial channel properties of the RS antenna port observed by the network entity.

[0264]

[0265] In one example, a type A or type B QCL parameter can be used to indicate that the target reference signal (RS) or the target signal and the source or reference RS (the RS provided in the QCL settings) are transmitted from the same TRP using different beams, so the Doppler information can be assumed to be similar, and the device does not need to derive it for the target signal or RS.

[0266] In another example, the target RS and the reference or source RS can be indicated to fall at similar angles of arrival, so the same Rx spatial filter can be applied to the device. This is indicated by the QCL type parameter.

[0267] The measurement timing, reporting, and configuration are described below.

[0268] Measurement devices measuring DL-RS can report multiple measurement instances (RSTD, DL RSRP, and / or UE Rx-Tx time difference measurements) to network nodes in a single measurement report for UE-assisted positioning. Measurement devices measuring UL RS can report multiple measurement instances (RTOA, UL RSRP, and / or gNB Rx-Tx time difference measurements) to network nodes in a single measurement report. Measurement instances can include measurement information from one or more measurement timestamps, which can be obtained by averaging multiple timestamps. Measurement instances can also refer to one or more measurements of the same or different types obtained from the same DL-RS / UL-RS. Measurement devices can report one or more measurement instances with one or more timestamps. In one example, for the same DL-RS or UL-RS measurement, two measurement results reported with the same timestamp may correspond to different reception characteristics at the measurement device. In embodiments, the measurement device may be, for example, a base station, or a TRP, or a UE, or another network entity of the wireless communication system.

[0269] The measuring device can be configured to report one or more measurement instances or measurement timestamps of a DL-RS / UL-RS resource or resource set. In one example, the measuring device can be configured to report one or more measurement results with timestamp information for one or more DL-RS or UL-RS measurement instances.

[0270] The transmission device can be configured to transmit one or more reference signals, wherein the configuration includes one or more parameters having time information. The transmission device can apply the parameters to send the configured reference signals at an indicated time.

[0271] The following describes a method performed by a base station according to one embodiment. A base station or gNB is also provided, wherein the base station or gNB is operable to perform any of the subject matter of the method steps described below.

[0272] As a key concept of the base station in this embodiment, the LMF provides the TRP with information about the directional or spatial filters to be applied.

[0273] According to an embodiment, a method performed by a base station (BS) is provided, the method comprising:

[0281] According to an embodiment, the instruction (202) includes one or more IDs of one or more DL resources, wherein each ID is associated with a single DL resource or resource set.

[0282] In an exemplary embodiment, one or more IDs are associated with one or more UL resources. The base station determines at least one transmit spatial filter or beam direction for one or more DL RSs for each UL resource or set based on spatial filter settings or beam direction settings. In some examples, one or more DL RSs may be indicated to the BS by the network node LMF. The BS applies the determined transmit spatial filter or beam direction to transmit one or more DL RSs. In an exemplary embodiment, one or more IDs are associated with one or more DL resources.

The BS applies the determined receive spatial filter or beam direction to receive one or more other UL RSs. In an exemplary embodiment, one or more IDs are associated with one or more DL resources. The base station determines at least one transmit spatial filter or beam direction for one or more other DL RSs for each DL resource or set, based on spatial filter settings or beam direction settings. In some examples, one or more other DL RSs may be indicated to the BS by the network node LMF. The BS applies the determined transmit spatial filter or beam direction to transmit one or more other DL RSs.

[0284] According to one embodiment, one or more second messages (202) may be associated with a first message, or may be part of a first message (201.a, 201.b, 201.c).

[0285] Below, an example of a first message received by a BS according to one embodiment is described.

[0286] Figure 5 The communication between the BS and LMF is shown.

[0287] In a corresponding embodiment, the BS can receive a request message from the LMF to perform one or more measurements of one or more UL RSs. The measurement request (201.a) includes an indication of at least one spatial filter or beam direction information for one or more UL-RS measurements and / or an indication of the measurement type. In some examples, the measurement type may correspond to “RSRP,” “RTOA,” “Rx-Tx-Time Difference,” or “AoA,” or a combination thereof. The base station performs measurements on one or more ULRS resources associated with one or more UL resource sets.

[0288] When the BS receives a measurement request or measurement request update on one or more UL RSs, the measurement request message may include information about the spatial filter or beam direction. Table 1 shows an example of configuration information in a measurement request from the LMF to the BS, where this information is part of the BS's measurement request list or measurement quantity information (or UL-RS configuration), as shown in Table 2.

[0289]

[0290] Table 1: Beam direction or spatial filter information is part of the BS measurement request list.

[0291]

[0292]

[0293] Table 2: Beam direction or spatial filter information is part of the BS measurement information or UL-RS configuration.

[0294] In corresponding embodiments, the BS provides information about the spatial filter or beam direction to the network node LMF. In some examples, in response to a measurement request, the BS can provide information about the spatial filter or beam direction (201.a). This information may include one or more IDs of one or more DL resources, where each ID is associated with a single DL resource or resource set. This information may include one or more IDs of one or more UL resources, where each ID is associated with a single UL resource or resource set. This information may include one or more UL resources or sets and / or one or more IDs of one or more DL resources or sets, indicated in message (202) or in response to a request in (201.b).

[0295] This information may include one or more ID pairs, where each ID pair includes at least two IDs, wherein a first ID is associated with a UL resource and a second ID is associated with a DL resource, or a first ID is associated with a DL resource and a second ID is associated with a UL resource. For the UL / DL resources associated with the ID pair, there may be a correspondence between their associated transmit and receive spatial filters or beam directions. In another instance, this information may include one or more ID pairs, where each ID pair includes at least two IDs, wherein a first ID is associated with a DL resource and a second ID is associated with another DL resource, or a first ID is associated with a UL resource and a second ID is associated with another UL resource. For the DL / DL or UL / UL resources associated with the ID pair, there may be a correspondence between their associated spatial filters or beam directions.

[0296] In a corresponding embodiment, the BS may receive a measurement request message (201.a) requesting the BS to provide timing information in the measurement report regarding the reception of one or more UL resources on one or more measurement instances. In some options, the BS may provide information about the receive spatial filters applied for receiving one or more UL resources. In some options, the BS may provide the same timing information (e.g., timestamps) for one or more measurements associated with one or more measurement reports for the same UL resource ID. This means that the BS can simultaneously perform multiple measurements on the same UL resource using different receive spatial filters and / or beam directions, and / or different component carriers.

[0297] In a corresponding embodiment, the BS can receive a message from the LMF that includes an information request regarding one or more DL-RS configurations. In response, the BS can provide the LMF with information about the DL-RS configuration, which includes at least one or more identifiers of one or more DL-RS resources, wherein the resources belong to one or more resource set IDs corresponding to a BS ID on a given frequency layer.

[0298] In one embodiment, the LMF may request the BS to modify one or more transmit space filters (e.g., their orientation) associated with one or more DL-RS resources. The BS, triggered by the LMF request in message (201.a) or message (201.b), may report the ID of the DL-RS resource. In one example, the BS may receive a configuration message (202) from the LMF, which includes an indication of at least one space filter or beam orientation for transmitting at least one or more DL-RS resources.

[0299] In one embodiment, the LMF may request the BS to modify one or more receiver spatial filters (e.g., their orientation) corresponding to one or more UL-RS resources. The ID of the UL-RS is generated by a BS report triggered by the LMF request in message (201.a) or message (201.b), or from a BS measurement report.

[0300] Below, an example of a first message received by BS 201c according to one embodiment is described.

[0301] In a corresponding embodiment, the BS can receive a message from the LMF indicating the activation or triggering of a DL-RS transmission. The BS can provide an activation response or activation failure to the LMF based on the provided activation request. After the activation response, the BS receives a configuration message (202) that includes an indication of at least one spatial filter or beam direction for transmitting at least one DL resource and / or one or more identifiers IDs of one or more activated or triggered downlink DL resources.

[0302] The following describes an example of configuration message 202 according to one embodiment:

This indication or information may include at least one ID of one or more reference DL RSs. The BS can use this information or indication to determine one or more transmit space filters for DL ​​RSs having directional characteristics similar to the reference DL RSs. In some examples, similar directional characteristics mean that at least one DL RS overlaps with a reference DL RS in the spatial domain.

[0306] In an exemplary embodiment, as part of a configuration message (202), the BS may receive from the LMF an indication or information for transmitting one or more DL RSs. This indication or information may include at least one ID of one or more reference UL RSs. The BS may use this information or indication to determine one or more transmit space filters for the DL-RSs, the one or more transmit space filters having similar directional characteristics to the space filters used to receive the one or more reference UL RSs. In some examples, similar directional characteristics mean that at least one DL-RS overlaps with a reference UL RS in the spatial domain.

[0307] In an exemplary embodiment, as part of a configuration message (202), the BS can receive information or indication from the LMF for receiving at least one UL RS. This information may include the IDs of one or more reference UL RSs. The BS can use this information or indication to select one or more receiving spatial filters for UL RS reception, the one or more receiving spatial filters having similar directional characteristics to the spatial filters used for receiving the one or more reference UL RSs. In some examples, similar directional characteristics mean that at least one UL RS overlaps with a reference UL RS in the spatial domain.

[0308] In an exemplary embodiment, as part of a configuration message (202), the BS can receive information or indication from the LMF for receiving at least one UL RS. This information may include the IDs of one or more reference DL RSs. The BS can use the received information to select one or more receive spatial filters for UL RS reception, the one or more receive spatial filters having directional characteristics similar to those of the transmit spatial filters used for transmission to the one or more reference DL RSs. In some examples, similar directional characteristics mean that at least one UL RS overlaps with a reference DL RS in the spatial domain.

[0329] The following describes an example of an uplink triggering procedure according to one embodiment:

[0330] Figure 6 An example of a UL-triggered beam assist procedure coordinated by the LMF is shown. Specifically, Figure 6 A procedure is shown for providing more than one configuration message (202) to a second BS (BS-2) to provide one or more spatial filters or beam directions for the reception of one or more UL-RSs in Phase 5 and / or the transmission of one or more DL-RSs in Phase 10. The LMF communicates with the first BS (BS-1) and the second BS (BS-2), wherein the first BS may configure means for UL-RS transmission on a primary or secondary cell. The second BS may not be able to configure such means or communicate directly with it.

[0331] In one example, the first BS may receive from the LMF a message including an information request (201.b) requesting information about one or more UL-RS configurations configured for the device by the first BS. The first BS may respond to the LMF and provide information about one or more UL-RS resources and / or one or more sets of UL-RS resources.

[0332] For UL-RS detection used for positioning purposes, there may be at least two options in the procedure following the measurement of UL-RS resources (in... Figure 6 (In phase 7-b). After measuring the UL-RS resources, the LMF indicates the spatial filter of the DL-RS to the base station (via indication 202) by indicating the ID of the ULRS to be used for DL ​​beamforming. Figure 6 (In stage 10). This instruction can be executed by the LMF together with an instruction for the ID of the DL RS that the spatial filter must be applied or not.

[0333] According to one embodiment, a base station is configured to receive an indication of one or more IDs of UL resources or resource sets and one or more IDs of DL resources from a network node LMF, wherein the spatial filter or beam direction for transmitting the indicated DL resources is derived from the spatial filter or beam direction for receiving one or more UL resources or resource sets.

[0334] According to one embodiment, a base station is configured to receive an indication of one or more IDs of a UL resource or resource set from a network node LMF, wherein the spatial filter or beam direction used by the base station to transmit one or more DL resources or resource sets is derived from the spatial filter or beam direction used at the base station to receive one or more indications of the UL resources or resource sets.

[0335] If the indication does not include the IDs of one or more DL RSs, the base station selects an independent beamforming DL RS, or the BS knows which DL RS to use, for example, those provided by the NR specification. Alternatively, the base station may inform the LMF of one or more IDs of the DL RS or set configured for DL-RS transmission.

[0336] According to one embodiment, a base station is configured to apply a spatial filter or beam direction to one or more DL RSs, the spatial filter or beam direction being derived from the spatial filter or beam direction of one or more UL RSs indicated by a network node LMF, wherein the DL RS to which the spatial filter or beam direction is applied is

[0337] - Indicated by LMF to the base station, or

[0338] - Selected by the base station, or

[0339] - Selected by the base station from the information provided by the LMF, or

[0340] - The base station is known (e.g., RS is provided in the NR specification).

[0341] If the base station selects to use the DL RS, it can optionally report the DL RS to the LMF.

[0342] According to an embodiment, the base station is configured to provide the IDs of one or more DL RSs to the network node LMF. The DL RS associated with the reported ID can be a DL RS that it can transmit in the downlink, and the report can be provided after receiving an indication from the LMF of UL resources for deriving spatial filters. The base station can obtain the spatial filter or beam direction of the reported DL RS from the UL RS indicated to the base station by the LMF.

[0343] When a base station uses a spatial filter or beam direction derived from one or more UL RSs for a DL RS, it can indicate the application of the spatial filter or beam direction to the UE.

[0344] According to one embodiment, a network node, base station, or LMF is configured to provide at least one of the following messages to a user equipment via the PHY layer or a higher layer:

[0345] -The UE derives the spatial filter or beam direction for receiving DLRS 'P' from the spatial filter or beam direction used for transmitting UL RS or UL RS set 'S', or

[0346] - The UE assumes that the spatial filter or beam direction for the base station to transmit DL RS'P is derived from the spatial filter or beam direction used to receive UL RS or RS set'S at the base station.

[0347] For example, this instruction can be performed by providing a TCI status reference (TCI = Transmission Configuration Indicator) to the DL RS'P' using a UL RS or RS set 'S'—the DL RS'P' can be provided with a TCI status having a QCL type 'D' associated with the UL RS'S'.

[0348] For example, the instruction can also be performed by providing the LPP instruction dl-RS-Info for the DL RS'P' using the UL RS or RS set—the DL RS'P' can be provided as a dl-RS-QCL-Info having a QCL type 'D' associated with the UL RS.

[0349] This procedure can occur between the UE and the base station, regardless of the DL RS selection process that occurs between the base station and the LMF.

[0350] Note: Any reference to the use of one or more DL or UL resources in any of the above embodiments may also mean including a set of DL or UL resources that use one or more resources.

[0351] The following describes an example of the BS receiving configuration message (202):

[0352] According to an embodiment, the BS can receive an exit or follow configuration message (202). This information message may include information about whether the UL resource or resource set and / or DL ​​resource or resource set originates from or is targeted at the reference device. The information message (20Y) may include one or more of the following parameters:

[0353] • One or more identifiers (IDs) of one or more UL resources and / or UL resource sets associated with the reference device.

[0354] • One or more identifiers (IDs) of one or more DL resources and / or DL ​​resource sets associated with the reference device.

[0355] • Instructions regarding reference equipment types

[0356] • Location information of reference equipment

[0357] • Orientation information from the reference device

[0358] In a corresponding embodiment, the BS uses one or more parameters in the information message (20Y) to estimate the LOS (line-of-sight) or NLOS (non-line-of-sight) channel state between the BS and the reference device. The BS may provide a measurement report in response to a measurement request, which includes an indication of the LOS or NLOS channel state of one or more UL-RSs originating from the reference device, or use information from the reference device to derive an LOS or NLOS indication for measurements originating from one or more UL-RSs originating from the UE.

[0359] The following describes an example according to one embodiment, in which the BS provides information about the application's settings in response to configuration message 202:

[0360] According to an embodiment, the BS may provide an LMF in response to (202) or by providing an indication in the measurement report regarding one or more transmit and / or receive spatial filters or beam directions derived on the application (202). This indication may include one or more IDs of UL and / or DL ​​resources, or a successful indication of the application configuration (202), or information regarding the application beam direction used for transmit and / or receive at the BS. The BS may indicate whether one or more IDs of the DL-RS or UL-RS are spatially associated with one or more IDs indicated in (202).

[0361] According to an embodiment, the BS may provide an LMF in response to (202) or by providing an indication in the measurement report regarding an updated selection of one or more transmit and / or receive space filters or beam directions selected by the BS, and may include at least one parameter or indication other than (202). This indication may include one or more IDs of UL and / or DL ​​resources or information regarding the application beam direction used for transmit and / or receive at the BS.

[0362] The following describes an example of verifying configuration messages according to one embodiment:

[0363] According to an embodiment, the indication (202) may include validity information regarding at least one or more identifiers (IDs) and / or one or more IDs of one or more UL resources and / or UL resource sets and / or one or more DL resources and / or DL ​​resource sets, to indicate at least one spatial filter or beam direction for receiving one or more UL resources. Verification information may include an indication of the time during which the configuration (202) is valid (e.g., SFN, hybrid SFN, time slot, second, system-specific timestamp, etc.). Verification information may include an indication of one or more time windows during which the configuration (202) may be applied. The time window may include an indication of one or more times during which the configuration will be applied to non-periodic, semi-persistent, or periodic UL-RS reception and / or DL-RS transmission.

[0364] The following describes the DL resource configuration according to an embodiment: as a specific example of the embodiment, three possible options are now described:

[0365] Option 1: Step 1: BS notifies LMF on DL resources (as in 201-b), Step 2: LMF provides configuration for one or more resources, Step 3: BS confirms or aborts.

[0366] Option 2: Step 1: The BS notifies the LMF on a set of configurable DL resources (as in 201-b), Step 2: The LMF provides the configuration of one or more resources, Step 3: The BS acknowledges or aborts.

[0367] Option 3: Step 1: The BS receives PRS utilization features from the LMF; the BS provides the LMF with information about the configured DL RS resources based on these features.

[0368] A flowchart illustrating a method for enabling beamdirection configuration for a BS-specific DL-RS is shown. Specifically, Figure 7An example of directional configuration for DL-RS is shown (Option 1). The base station can receive a request from the LMF to provide information about one or more DL-RS configured at the base station. In response to this request, the base station can provide information or configuration for one or more DL-RS. The provided information may be, for example, part of a BS information item, including DL-RS configurations as shown in Table 3. This information may include spatial direction information for one or more DL-RS resource set IDs or resource IDs. In one embodiment, the LMF uses the spatial direction information received from the base station to generate a configuration indicating the spatial filter or beam direction of one or more DL-RS, or to update or reconfigure the directional or spatial settings of one or more DL-RS.

[0369]
