Background Art

[0002] In a communication system (e.g., a new radio (NR) system), a terminal device and a base station can transmit and receive pilot signals in a beam scanning manner without knowing each other's relative directions. For example, when the terminal device is not accessing the base station, the terminal device and the base station can transmit and receive pilot signals in a beam scanning manner. However, when transmitting and receiving pilot signals in this way, problems such as a decrease in resource utilization efficiency, an extension of reception time, and an increase in device power consumption occur.

It should be understood that the description of the related technologies or related terms is part of the technical solution of the present application and can be arbitrarily combined with the technical solution of the present application. Communication System Architecture

[0018] FIG. 1 is a diagram showing the system architecture of a wireless communication system 100 that can be applied to an embodiment of the present application. This wireless communication system 100 may include a base station 110 and a terminal device 120. The base station 110 may be a device that communicates with the terminal device 120. The base station 110 can provide communication coverage in a specific geographical area and communicate with the terminal device 120 located within this coverage area.

[0019] FIG. 1 exemplarily shows one base station and two terminal devices. Optionally, this wireless communication system 100 may further include a plurality of base stations, and within the coverage range of each base station, any number of other terminal devices may be included, and the embodiments of the present application do not limit this.

[0020] Optionally, this wireless communication system 100 may further include other network entities such as a network controller and a mobility management entity, and the embodiments of the present application do not limit this.

[0021] The solutions of the embodiments of this application can be applied to various communication systems, such as global system of mobile communication (GSM) systems, code division multiple access (CDMA) systems, wideband code division multiple access (WCDMA®) systems, general packet radio service (GPRS), long term evolution (LTE) systems, advanced long term evolution (LTE-A) systems, new radio (NR) systems, NR system evolution systems, LTE-based access to unlicensed spectrum (LTE-U) systems, NR-based access to unlicensed spectrum (NR-U) systems, non-terrestrial networks (NTN) systems, universal mobile telecommunication systems (UMTS), and wireless local area networks. It can be applied to other communication systems such as networks (WLAN), wireless fidelity (WiFi), and 5th-generation (5G) communication systems, as well as future communication systems, such as 6th-generation mobile communication systems or satellite communication systems.

[0022] Conventional communication systems typically have limitations on the number of connections they can support, and are relatively easy to implement. However, with advancements in communication technology, mobile communication systems not only support conventional communication but also device-to-device (D2D) communication, machine-to-machine (M2M) communication, machine-type communication (MTC), vehicle-to-vehicle (V2V) communication, and vehicle-to-vehicle / vehicle-to-infrastructure (V2X) communication. The embodiments of this application can also be applied to these communication systems.

[0023] The communication system in the embodiment of the present invention can be applied to carrier aggregation (CA) scenarios, dual connectivity (DC) scenarios, and standalone (SA) networking scenarios.

[0024] The communication system in the embodiment of this application can be applied to the unlicensed spectrum. The unlicensed spectrum can also be considered a shared spectrum. Alternatively, the communication system in the embodiment of this application can also be applied to the licensed spectrum. The licensed spectrum can also be considered a dedicated spectrum.

[0025] Embodiments of this application can be applied to NTN systems and terrestrial network (TN) systems. In non-limiting examples, NTN systems include NR-based NTN systems and Internet of Things (IoT)-based NTN systems. Exemplary, in a scenario where narrowband internet of things (NB-IoT) and enhanced machine type communication (eMTC) access NTN, a system consisting of IoT terminal devices and an NTN network can be understood as an IoT-based NTN system.

[0026] In the embodiments of this application, terminal equipment may also be called user equipment (UE), access terminal, user unit, user station, mobile station (MS), mobile terminal (MT), remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent, or user device. In the embodiments of this application, terminal equipment may also refer to devices that provide voice and / or data connectivity to a user, and can be used to connect humans, objects, and machines, such as handheld devices and in-vehicle devices with wireless connectivity. The terminal devices in the embodiments of this application may include mobile phones, tablet PCs (Pads), notebook computers, palmtop computers, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in self-driving, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes. Optionally, the UE can function as a base station. For example, the UE can function as a scheduling entity, providing sidelink signals between UEs in V2X or D2D, etc. For example, a cellular phone and a car communicate with each other using sidelink signals. Communication between a cellular phone and smart home devices does not require relaying communication signals by a base station.

[0027] In the embodiments of the present invention, the base station may be a device for communicating with terminal equipment, and this base station may also be called an access base station or a radio access base station, for example, a base station may be a base station. In the embodiments of the present invention, the base station may refer to a radio access network (RAN) node (or device) that provides terminal equipment to a radio network. The term "base station" broadly covers, or may be replaced by, various names such as NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, access point, transmitting and receiving point (TRP), transmitting point (TP), main base station (MeNB), secondary base station (SeNB), multi-standard radio (MSR) node, home base station, network controller, access node, radio node, access point (AP), transmitting node, transceiver node, base band unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), and positioning node. A base station may also be a macro base station, micro base station, relay node, donor node, or similar, or a combination thereof. A base station may further refer to a communication module, modem, or chip installed within the equipment or device mentioned in the preceding paragraph. A base station may also refer to equipment that functions as a base station in mobile switching centers and device-to-device (D2D), vehicle-to-everything (V2X), and machine-to-machine (M2M) communications, network-side equipment in a 6G network, or equipment that functions as a base station in a future communication system.A base station can support a network of the same or different access technologies. The embodiments of this application do not limit the specific technologies and specific equipment used in the base station.

[0028] Base stations may be fixed or mobile. For example, a helicopter or drone may be configured as a mobile base station, and one or more cells may move depending on the location of this mobile base station. In another example, a helicopter or drone may be configured as equipment for communicating with another base station.

[0029] In some deployments, the base station in the embodiments of the present invention refers to a CU or DU, or the base station may include both a CU and a DU. The gNB may further include an AAU.

[0030] Base stations and terminal equipment may be configured on land, including indoors or outdoors, handheld or vehicle-mounted, on water, or in the air on airplanes, balloons, or satellites. The embodiments of this application do not limit the scenarios in which the base stations and terminal equipment are located.

[0031] It should be understood that all or some of the functions of the communication equipment in this application may be implemented by software functions running on the hardware, or by virtualization functions instantiated on a platform (e.g., a cloud platform). Positioning technology in communication systems

[0032] Referring to Figure 2, the communication system 100 may further include a positioning device 130. The positioning device 130 may be used to determine the location information of a terminal device. The positioning device 130 may be located in the core network. The positioning device 130 may be called a positioning server. Taking an NR system as an example, the positioning device 130 may be a location management function (LMF). Taking other communication systems as an example, the positioning device 130 may be a location management unit (LMU), a location management center (LMC), or an evolved serving mobile location center (E-SMLC). It can be understood that the positioning device 130 may further be other network elements, nodes, or devices for determining the location information of a terminal device, for example, a network element or node for determining the location information of a terminal device in a future communication system, and the embodiments of this application do not particularly limit the name of the positioning device.

[0033] Positioning in the communication system 100 includes uplink positioning and downlink positioning. A certain communication system (such as an NR system) performs downlink positioning based on a positioning reference signal (PRS). The PRS may also be called a downlink positioning reference signal (DL-PRS) and is a reference signal used in the positioning function. For example, in the downlink positioning process, terminal device 120 can first measure the PRS transmitted by the serving cell and adjacent cells (also called adjacent cells) and estimate the relevant information for the positioning measurement. Next, terminal device 120 can report the relevant information for the positioning measurement as the PRS measurement result to positioning device 130. Positioning device 130 can analyze the position of terminal device 120 based on the relevant information for the positioning measurement reported by terminal device 120 and obtain the position information of terminal device 120. For example, positioning device 130 can calculate the position information of terminal device 120 based on trilateration or triangulation.

[0034] A certain communication system (such as an NR system) performs uplink positioning based on a sounding reference signal (SRS). For example, in the uplink positioning process, terminal device 120 transmits an SRS. Base stations 110 (serving cell base station and adjacent cell base stations) can obtain measurement results based on the SRS transmitted by the terminal. The measurement results of the SRS may include information related to the positioning measurement. Next, base station 110 can transmit the information related to the positioning measurement to positioning device 130. Positioning device 130 can analyze the position of terminal device 120 based on the information related to the positioning measurement reported by base station 110 and obtain the position information of terminal device 120. For example, positioning device 130 can calculate the position information of terminal device 120 based on trilateration or triangulation.

[0035] In some embodiments, the communication system performing uplink positioning based on SRS may include the communication system performing uplink positioning based on SRS for positioning (SRS-Pos).

[0036] In some embodiments, when a terminal device transmits an SRS, the spatial relation information associated with the SRS determines which SRS resource is used to transmit the SRS. Therefore, in some embodiments, the network can configure one or more SRS resources on the terminal device, and these one or more SRS resources may be associated with different spatial relation information. Taking SRS-Pos as an example, in Rel-16, the network can configure multiple SRS-Pos resources on the terminal device, and different SRS-Pos resources are associated with different spatial relation information.

[0037] In some embodiments, the spatial relation information associated with the SRS is related to the location of the terminal equipment. Alternatively, the spatial relation information associated with the SRS may be determined by the location of the terminal equipment. Therefore, when the terminal equipment and the base station do not know each other's relative orientation, how to determine the resource to transmit the SRS or how to send and receive the SRS is a problem to be solved. In a possible embodiment, the base station can perform an SRS (e.g., SRS-Pos) beam scan to ensure that the serving cell and adjacent cells can receive the SRS.

[0038] The positioning measurement information mentioned above may include one or more of the following: time information, distance information, power information, and angle information. More specifically, the positioning measurement information may include one or more of the following: time difference of arrival (TDOA), angle difference of arrival (ADOA), reference signal receive power (RSRP), etc. Low power consumption terminal devices

[0039] Communication systems can support various types of terminal equipment. For example, some communication systems (e.g., NR systems) can support low-power terminal equipment (low-power UE, LPUE), which may also be called low-power UEs.

[0040] Low-power UE (Unified Element) can be understood as UE implemented using technologies that reduce the power consumption of devices without degrading communication quality. Low-power UE technology is advantageous in reducing the power consumption of devices and extending their battery life, providing longer range for devices such as smart wearables and Internet of Things. Furthermore, low-power UE technology is advantageous in improving network capacity and coverage range, thereby enhancing network performance and user experience.

[0041] In some embodiments, the low-power UE may include, for example, a low-power high-accuracy positioning (LPHAP) UE.

[0042] In some embodiments, the low-power UE may include, for example, a reduced capability (RedCap) UE. In some embodiments, the RedCap UE may be called a low-capacity UE.

[0043] In some embodiments, low-power UEs may include terminal devices with low data transmission rate and bandwidth requirements, such as sensors and wearable devices.

[0044] As mentioned above, in some communication systems (e.g., NR systems), a challenge to be solved is how to determine which resource to send and receive pilot signals (e.g., SRS, PRS, etc.) between terminal equipment and base stations, or how to send and receive pilot signals, without knowing each other's relative directions. For example, how should the resource to send and receive pilot signals be determined, or how should pilot signals be sent and received, when terminal equipment is not accessing a base station?

[0045] The embodiments of this invention are not limited to scenarios where terminal equipment does not access a base station. Taking a low-power UE as an example, when the low-power UE moves between cells, it may not need to access cells in order to reduce power consumption due to cell access. In other words, the low-power UE may not need to access a base station when moving between cells. Then, after the low-power UE moves to a new cell and / or performs cell reselection, the spatial relationships of the UE may change accordingly, and it may be necessary to update the spatial relationships. In this case, how to determine the resources to send and receive pilot signals when cell access is not performed is a problem that needs to be solved.

[0046] In a possible embodiment, terminal equipment and base stations can determine resources for transmitting and receiving pilot signals using a beam scanning method. However, transmitting and receiving pilot signals in this manner leads to problems such as reduced resource utilization efficiency, extended reception time, and increased power consumption of the equipment.

[0047] For example, the network side configures multiple resources on each terminal device (e.g., a low-power UE) to send and receive pilot signals, and the network side configures multiple SRS resources on each terminal device to send and receive SRS signals. In this case, the network side needs to reserve a large amount of resources, causing a decrease in resource utilization. Furthermore, terminal devices and / or base stations need to perform beam scans on each resource, and each beam scan requires the reception of multiple periodic pilot signals, causing delays in reception. In addition, during beam scanning, there may be no corresponding receiver (e.g., a base station) to receive pilot signals in a certain direction of the beam scan transmitting pilot signals, wasting resources in those directions and further increasing the power consumption of the equipment.

[0048] To solve the above problems, an embodiment of the present invention provides a wireless communication method and communication device that can determine the resources to send and receive pilot signals based on the correspondence between the beam scanning direction and the time-domain position (i.e., the first information described below), which is advantageous in avoiding the need to send and receive pilot signals using a beam scanning method, thereby improving resource utilization, reducing reception delay, and reducing the power consumption of the equipment. An embodiment of the method of the present invention will be described below with reference to the drawings.

[0049] Figure 3 is a flowchart of a wireless communication method according to one embodiment of the present invention. The method shown in Figure 3 will be described from the perspective of interaction between terminal equipment and a base station. The terminal equipment and base station may be, for example, the terminal equipment 120 and base station 110 shown in Figure 1. The method shown in Figure 3 may include step S310, which will be described below.

[0050] In step S310, the terminal device transmits and receives the first pilot signal.

[0051] In some embodiments, the terminal device can transmit a first pilot signal, for example, to a base station.

[0052] In some embodiments, the terminal equipment can receive a first pilot signal, for example, a first pilot signal transmitted from a base station.

[0053] In some embodiments, when a terminal device transmits a first pilot signal, the first pilot signal may be an uplink pilot signal, such as an SRS.

[0054] In some embodiments, when a terminal device receives a first pilot signal, the first pilot signal may be a downlink pilot signal, for example, a PRS.

[0055] In some embodiments, the first pilot signal may also be called the first reference signal; that is, in the embodiments of the present invention, the pilot signal and the reference signal may be interchangeable, and the pilot signal will be described below as an example.

[0056] The embodiments of this application do not limit the type of the first pilot signal, and it may be any type of pilot signal. For example, the first pilot signal may be a pilot signal for channel estimation. Or, the first pilot signal may be a pilot signal for positioning. Alternatively, the first pilot signal may be a pilot signal for calibration, etc.

[0057] For example, the first pilot signal may include one or more signals from among SRS, PRS, channel state information reference signal (CSI-RS), tracking reference signal (TRS), synchronization signal block (SSB), cell reference signal (CRS), demodulation reference signal (DRS), physical broadcast channel (PBCH), primary synchronization signal (PSS), secondary synchronization signal (SSS), etc.

[0058] In some embodiments, if the first pilot signal includes an SRS, the SRS may be of any type. For example, the first pilot signal may be a periodic SRS, aperiodic SRS, a semi-persistent SRS, or the first pilot signal may be an SRS-Pos, or the first pilot signal may be an SRS other than an SRS-Pos.

[0059] In some embodiments, if the first pilot signal includes a PRS, the PRS may be of any type. For example, the first pilot signal may be a periodic PRS, a non-periodic PRS, an on-demand PRS, etc.

[0060] Naturally, if the first pilot signal includes other signals (e.g., CSI-RS, SSB, etc.), these other signals can also be of any type, and for the sake of brevity, they will not be explained again here.

[0061] In some embodiments, the resource that sends and receives the first pilot signal (or referred to as the pilot resource) is determined based on the first information.

[0062] In some embodiments, the resources that transmit and receive the first pilot signal may include one or more resources such as time-domain resources, frequency-domain resources, spatial-domain resources, and code-domain resources. For example, the first information may be used to determine the time-domain resource that transmits and receives the first pilot signal, for example, at which time-domain location the first pilot signal is transmitted and received. In another example, the first information may be used to determine the location of the frequency-domain resource that transmits and receives the first pilot signal, for example, at which frequency-domain location the first pilot signal is transmitted and received. In yet another example, the first information may be used to determine the spatial-domain resource that transmits and receives the first pilot signal, for example, at which beam (spatial relationship) the first pilot signal is transmitted and received.

[0063] In some embodiments, the first information may be associated with or related to the beam scanning direction of a pilot signal (e.g., a first pilot signal). That is, the first information may be used to indicate the beam scanning direction of the pilot signal.

[0064] In some embodiments, the first information may be associated with, or related to, the beam scanning direction and time-domain position of a pilot signal. For example, the first information may be used to indicate a correspondence (or association) between one or more beam scanning directions and one or more time-domain positions. In some embodiments, the one or more beam scanning directions are one or more beam scanning directions corresponding to a pilot signal (e.g., a first pilot signal).

[0065] In the embodiment of the present invention, the resource that transmits and receives the first pilot signal is determined based on first information. Thus, terminal equipment and base stations only need to transmit and receive the first pilot signal in the direction corresponding to a certain time-domain position at a certain time-domain position based on the same correspondence. This is advantageous because it avoids the need to transmit and receive the first pilot signal using a beam scanning method, thereby improving resource utilization, reducing reception delay, and reducing equipment power consumption.

[0066] For example, in response to a first pilot signal transmitted from a terminal device, the base station does not need to know the direction of the terminal device. The base station does not need to use a different direction to receive the first pilot signal (e.g., multiple periodic signals). In other words, the base station does not need to perform beam scanning and can receive the first pilot signal in the corresponding direction based on the first information. This is advantageous in terms of improving resource utilization, reducing reception delay, and reducing equipment power consumption.

[0067] Alternatively, in response to a first pilot signal transmitted from a base station, the terminal equipment does not need to know the direction of the base station. The terminal equipment does not need to use a different direction to receive the first pilot signal, meaning the terminal equipment does not need to perform beam scanning. Instead, it can receive the first pilot signal in the corresponding direction based on the first information, which is advantageous for improving resource utilization, reducing reception delay, and reducing the power consumption of the equipment.

[0068] The following provides a more detailed explanation of the first piece of information.

[0069] In some embodiments, the first information may be determined based on reference information for the first information. For example, the first information may be determined based on rules and reference information defined in the protocol.

[0070] In some embodiments, the first information may be determined by the terminal equipment and / or base station based on rules and standard information specified in the protocol.

[0071] The embodiments of this application do not limit the specific content of the reference information, and it is sufficient that it can be used to determine the first information, or that it can be used to determine the correspondence between the beam scanning direction and the time-domain position. For example, the reference information may be positioning-related information of the terminal equipment, equipment information of the terminal equipment, network information of the serving cell or adjacent cell, etc.

[0072] In some embodiments, the first information may include correspondences between adjacent cells and / or serving cells. That is, the first information may include correspondences between one or more beam scanning directions of adjacent cells and one or more time-domain positions, and / or correspondences between one or more beam scanning directions of serving cells and one or more time-domain positions.

[0073] In some embodiments, the first information may include related instruction information indicating whether the correspondence of adjacent cells conforms to the same criterion information as the serving cell. In other words, the first information may include first instruction information, which is used to indicate whether the correspondence of adjacent cells conforms to the same criterion information as the serving cell. For example, the first information may be used to instruct adjacent cells and the serving cell to determine the first information (or the correspondence) in accordance with the same criterion information. Alternatively, the first information may be used to instruct adjacent cells and the serving cell to determine the first information in accordance with different criterion information.

[0074] In some embodiments, the first information may directly indicate the correspondence between one or more beam scanning directions and one or more time-domain positions. For example, the first information may include the correspondence between one or more beam scanning directions and one or more time-domain positions.

[0075] In some embodiments, the first information may indirectly indicate the correspondence between one or more beam scanning directions and one or more time-domain positions. For example, the first information may include the correspondence between one or more beam scanning directions and one or more pilot resources (which may be abbreviated as resources). This may include the time-domain positions corresponding to the one or more pilot resources, i.e., the one or more pilot resources may be used to transmit pilot signals at any time-domain position. In this way, the correspondence between one or more beam scanning directions and one or more time-domain positions can be determined based on the correspondence between one or more beam scanning directions and one or more pilot resources.

[0076] In some embodiments, the first information may simultaneously include correspondences between one or more beam scanning directions and one or more time-domain positions, and correspondences between one or more beam scanning directions and one or more pilot resources. For example, if the first information indicates or constitutes a group of correspondences, some of the correspondences in the group of correspondences may include correspondences between one or more beam scanning directions and one or more time-domain positions, and other correspondences in the group of correspondences may include correspondences between one or more beam scanning directions and one or more pilot resources.

[0077] For each beam scanning direction, terminal equipment can determine at which time-domain position the pilot signal corresponding to each beam scanning direction should be transmitted and received, based on the correspondence between one or more beam scanning directions and one or more time-domain positions. Accordingly, base stations can determine at each time-domain position which pilot signal corresponding to each beam scanning direction should be transmitted and received, based on the correspondence between one or more beam scanning directions and one or more time-domain positions.

[0078] The correspondence between one or more beam scanning directions and one or more time-domain positions mentioned above can be seen in the example in Figure 4. In the example in Figure 4, the ellipses represent different time-domain positions, the different arrows within the ellipses represent different beam scanning directions, the different beam scanning directions correspond to different time-domain positions, and different beams in different directions are transmitted at different time-domain positions. As a specific example, a terminal device can transmit a beam in the 0° direction at the first time-domain position (first time unit), which is used to transmit a pilot signal (e.g., SRS), a beam in the 30° direction for transmitting a pilot signal at the second time-domain position, a beam in the 60° direction for transmitting a pilot signal at the third time-domain position, and by analogy, a beam in the 360° direction for transmitting a pilot signal at the twelfth time-domain position. In response to this, the base station can receive a pilot signal in the 180° direction at the first time-domain position, in the 210° direction at the second time-domain position, in the 240° direction at the third time-domain position, and by analogy, in the 12th time-domain position, it can receive a pilot signal in the 150° direction. Through this process, alignment of the received beam and the transmitted beam can be reliably achieved at each time-domain position.

[0079] In the embodiments of this invention, the beam scanning direction may be any direction, such as 0°, 15°, or 30°.

[0080] Furthermore, the embodiments of this application do not specifically limit the interval between different beam scanning directions. For example, although the above example uses a 30° interval, the embodiments of this application are not limited to this. For example, the interval between different beam scanning directions may be other values ​​such as 15° or 60°, and can be set according to the actual situation.

[0081] In some embodiments, the correspondence between one or more beam scanning directions and one or more time-domain positions may be a one-to-one correspondence. For example, the first beam scanning direction corresponds to the first time-domain position, the second beam scanning direction corresponds to the second time-domain position, and the third beam scanning direction corresponds to the third time-domain position. However, embodiments of the present invention are not limited thereto, and for example, the correspondence between one or more beam scanning directions and one or more time-domain positions may be a one-to-many correspondence. As an example, the scanning direction of the first beam corresponds to the first time-domain position and the second time-domain position, and in this way, terminal equipment can transmit and receive the first pilot signal in the scanning direction of the first beam at both the first and second time-domain positions.

[0082] In some embodiments, the correspondence between one or more beam scanning directions and one or more pilot resources may be a one-to-one correspondence. For example, the first beam scanning direction corresponds to the first resource, the second beam scanning direction corresponds to the second resource, and the third beam scanning direction corresponds to the third resource. However, embodiments of the present application are not limited thereto, and for example, the correspondence between one or more beam scanning directions and one or more pilot resources may be a one-to-many correspondence. As an example, the scanning direction of the first beam corresponds to the first resource and the second resource, and in this way, at the time-domain positions corresponding to the first resource and the time-domain positions corresponding to the second resource, terminal equipment can both transmit and receive the first pilot signal in the scanning direction of the first beam.

[0083] In some embodiments, the correspondence between one or more beam scanning directions and one or more pilot resources can be indicated using the correspondence between one or more beam scanning directions and one or more resource numbers (resource IDs). For example, with respect to SRS resources, the correspondence between one or more beam scanning directions and one or more SRS resources can be indicated using one or more beam scanning directions and one or more SRS resource IDs.

[0084] In some embodiments, the resource ID may be used to uniquely identify a single resource.

[0085] In some embodiments, the resource ID is carried when the base station allocates the resource to the terminal equipment.

[0086] In some embodiments, the beam scanning direction should be understood as the direction (or spatial direction, angle, etc.) in which pilot signals are transmitted and received, for example, the direction in which the first pilot signal is transmitted and received. To give an example where the beam scanning direction is the direction in which pilot signals are transmitted, one example would be that if the beam scanning direction is 30°, pilot signals are transmitted to the left and right in the 30° direction, and another example would be that if the beam scanning direction is 90°, pilot signals are transmitted to the left and right in the 90° direction. To give an example where the beam scanning direction is the direction in which pilot signals are received, one example would be that if the beam scanning direction is 30°, pilot signals are received to the left and right in the 30° direction, and another example would be that if the beam scanning direction is 90°, pilot signals are received to the left and right in the 90° direction.

[0087] In some embodiments, the beam scanning direction may be replaced with other terms such as beam transmission / reception direction, beam transmission / reception angle, beam scanning angle, beam transmission direction, beam reception direction, beam transmission angle, beam reception angle, etc., and the embodiments of the present application are not limited thereto.

[0088] In some embodiments, the time-domain position may be replaced with other terms such as time or time unit, and the embodiments of this application are not limited thereto. For example, the first information may be used to indicate the correspondence between one or more beam scanning directions and one or more time-domain positions, or alternatively, the first information may be used to indicate the correspondence between one or more beam scanning directions and one or more times (time units).

[0089] The embodiments of this application do not specifically limit the units of time-domain positions. Exemplarily, a time-domain position may include one or more of the following: subframes, slots, symbols, etc.

[0090] The embodiments of this application do not limit the origin of the first information. In some embodiments, the first information may be configured by a base station, or the first information may be transmitted by a base station to a terminal device. For example, a base station may transmit the first information to a terminal device by upper-layer signaling (e.g., radio resource control (RRC) signaling), or by broadcast signaling, or by system information. In some embodiments, the first information may be predefined or preconfigured by a protocol.

[0091] In some embodiments, the base station or protocol may specify that one or more beam scanning directions are associated with one or more time-domain positions (or one or more pilot resources) in a sequential order, for example, one or more beam scanning directions are associated one-to-one with one or more time-domain positions (or one or more pilot resources) in a sequential order. The terminal equipment can then transmit and receive pilot signals based on the same (or fixed) correspondence, for example, it can sequentially transmit and receive pilot signals based on the same correspondence.

[0092] In some embodiments, the number of beam scanning directions in the correspondence indicated by the first information may be equal to the number of resources configured on the terminal device by the network. For example, the correspondence indicated by the first information includes four beam scanning directions (0°, 30°, 60°, and 90°, respectively), and the number of resources configured on the terminal device by the network is also four (e.g., resource 1, resource 2, resource 3, and resource 4). In this case, a one-to-one correspondence can be established between the beam scanning directions and the configured resources. For example, the 0° beam scanning direction corresponds to resource 1, the 30° beam scanning direction corresponds to resource 2, the 60° beam scanning direction corresponds to resource 3, and the 90° beam scanning direction corresponds to resource 4.

[0093] In some embodiments, the number of beam scanning directions in the correspondence indicated by the first information may be less than the number of resources configured on the terminal device by the network. For example, the correspondence indicated by the first information includes three beam scanning directions (0°, 30°, and 60°, respectively), and the number of resources configured on the terminal device by the network is four (e.g., resource 1, resource 2, resource 3, and resource 4). In this case, a one-to-one correspondence can be established between the beam scanning directions and the configured resources. For example, the 0° beam scanning direction corresponds to resource 1, the 30° beam scanning direction corresponds to resource 2, and the 60° beam scanning direction corresponds to resource 3, or the 0° beam scanning direction corresponds to resource 2, the 30° beam scanning direction corresponds to resource 3, and the 60° beam scanning direction corresponds to resource 4, and so on.

[0094] In other words, if the number of beam scanning directions in the correspondence indicated by the first information is less than the number of resources configured on the terminal equipment by the network side, a one-to-one correspondence can be established between the resources that constitute the beam scanning directions. For example, a one-to-one correspondence can be established between the beam scanning direction and the configured resources starting from the first beam of the beam scan. Alternatively, a one-to-one correspondence can be established between the beam scanning direction and the resources that constitute it starting from the nth (n≧2)th beam of the beam scan. In this way, the resources that transmit and receive the first pilot signal can then be determined based on this one-to-one correspondence (for example, determining the direction in which the first pilot signal is transmitted and received, or determining the time-domain position for receiving the first pilot signal).

[0095] In some embodiments, the number of beam scanning directions in the correspondence indicated by the first information may be greater than the number of resources configured by the network on the terminal device, i.e., the number of resources configured by the network on the terminal device is less. In some embodiments, the resources configured by the network on the terminal device include angular information, and if the beam scanning direction is the same as the angle of the resource configured by the network on the terminal device, the beam transmission and reception time can be determined based on the correspondence between the beam scanning direction and the time-domain position or the correspondence between the beam scanning direction and the resource.

[0096] In some embodiments, if there are n beam scanning directions, m resources configured on the network side in the terminal equipment, and n is an integer multiple of m, then the i-th resource (i ≤ m) can be associated with the i*n / m-th beam scanning direction. For example, typically the i-th resource can be associated with the i*floor(n / m)-th beam scanning direction.

[0097] In some embodiments, the first information may be used to indicate a correspondence between one or more groups. Each group in the one or more group correspondence is used to indicate a correspondence between one or more beam scanning directions and one or more time-domain positions. For example, each group in the one or more group correspondence may include a correspondence between one or more beam scanning directions and one or more time-domain positions, or each group in the one or more group correspondence may include a correspondence between one or more beam scanning directions and one or more pilot resources, etc.

[0098] In other words, the first information is used to indicate the correspondence between one or more sets, and the correspondence between each set is used to indicate the correspondence between one or more beam scanning directions and one or more time-domain positions. For example, the correspondence between each set may include the correspondence between one or more beam scanning directions and one or more time-domain positions, or the correspondence between each set may include the correspondence between one or more beam scanning directions and one or more pilot resources, etc.

[0099] As one implementation, the first information may be used to indicate the correspondence between groups. In this case, the terminal equipment of a group can determine which resources to send and receive pilot signals using the same group correspondence (for example, determining the direction in which to send and receive pilot signals, or determining the time-domain position in which to send and receive pilot signals). As an example, the terminal equipment of a group can sequentially transmit pilot signals using the same / fixed beam scanning direction.

[0100] The embodiments of this application do not specifically limit the definition and division method of a group of terminal devices, and a group of terminal devices is used to refer to one or more terminal devices, which may be, for example, terminal devices in the same cell or terminal devices in different cells. For example, the group of terminal devices constitutes a first terminal device group, and the terminal devices in the first terminal device group may be located in the same cell or in different cells.

[0101] In some embodiments, the group of terminal devices may be one or more terminal devices located in the same effective area. Within the effective area, the pilot signals of the terminal devices (e.g., SRS, PRS, etc.) do not change when the terminal devices move. In some embodiments, the effective area may be located within a single cell. In some embodiments, the effective area may span multiple cells.

[0102] In other words, if the first information is used to indicate a group correspondence, then the terminal devices of that group (for example, all terminal devices in the first terminal device group) can use the same group correspondence to determine which resources send and receive the first pilot signal.

[0103] As an example, considering that the pilot resources of a terminal device need to be received by multiple base stations, for example in an uplink positioning scenario, the pilot resources of a terminal device need to be received by multiple base stations, and therefore, base stations need to configure multiple pilot resources for each terminal device. As a result, the base station needs to occupy a lot of resources, and resource waste is likely to occur. Therefore, in some embodiments, a base station can configure the same pilot resources for different terminal devices (e.g., a group of terminal devices) in order to conserve resources. In this case, the base station can configure the same correspondence (e.g., same group correspondence) for the terminal devices in the group of terminal devices in order to determine which resources the group of terminal devices will use to send and receive pilot signals.

[0104] However, referring to Figure 5, if the pilot resources configured in the terminal equipment of one group are the same and pilot signals are transmitted and received using the same group correspondence, resource collision problems are likely to occur if some of the terminal equipment in the group have the same beam scanning direction and are located close together.

[0105] To address this problem, another embodiment of the present invention is proposed, in which the first information may be used to indicate the correspondence between multiple groups. In this case, a group of terminal devices can determine the resources to send and receive pilot signals using different correspondences (for example, determining the direction in which pilot signals are sent and received, or determining the time-domain location in which pilot signals are sent and received).

[0106] In other words, when the first information is used to indicate the correspondence between multiple groups, some or all of the terminal devices in one group (e.g., the first terminal device group) can determine which resources send and receive the first pilot signal using different group correspondences. For example, one group of terminal devices includes a first terminal device, a second terminal device, and a third terminal device, and the first information is used to indicate the correspondence between two groups, so the first and second terminal devices can determine which resources send and receive the first pilot signal using the correspondence between the first group, and the third terminal device can determine which resources send and receive the first pilot signal using the correspondence between the second group. Alternatively, one group of terminal devices includes a first terminal device, a second terminal device, and a third terminal device, and the first information is used to indicate the correspondence between three groups, so the first terminal device can determine which resources send and receive the first pilot signal using the correspondence between the first group, the second terminal device can determine which resources send and receive the first pilot signal using the correspondence between the second group, and the third terminal device can determine which resources send and receive the first pilot signal using the correspondence between the third group, and so on.

[0107] For example, a base station can configure the same pilot resource for different terminal devices (e.g., a group of terminal devices) to conserve resources. In this case, the base station can configure different correspondences within that group of terminal devices to avoid resource collisions. Alternatively, if a group of terminal devices supports correspondences for multiple groups, the terminal devices within that group can send and receive pilot signals using different beam scanning directions, thus avoiding resource collisions in the time-frequency-space dimensions. In some cases, the positions of the terminal devices may collide, but it is unlikely that this will not occur in all beam scanning directions.

[0108] In some embodiments, when the first information is used to indicate a correspondence between multiple groups, the correspondence between multiple groups may be for different groups of terminal equipment, and terminal equipment in the same group of terminal equipment may use the same group correspondence. For example, the first information may be used to indicate a correspondence between three groups, the first group correspondence may be applied to the first group of terminal equipment, and all terminal equipment in the first group of terminal equipment may use the first group correspondence to determine which resources send and receive pilot signals; the second group correspondence may be applied to the second group of terminal equipment, and all terminal equipment in the second group of terminal equipment may use the second group correspondence to determine which resources send and receive pilot signals; and the third group correspondence may be applied to the third group of terminal equipment, and all terminal equipment in the third group of terminal equipment may use the third group correspondence to determine which resources send and receive pilot signals. However, the embodiments of the present application are not limited thereto. For example, the first information may be used to indicate a correspondence between three groups, the correspondence between the first group and the correspondence between the second group may be applied to a first group of terminal devices, some terminal devices in the first group of terminal devices may use the correspondence between the first group to determine which resources to send and receive pilot signals, some terminal devices may use the correspondence between the second group to determine which resources to send and receive pilot signals, the first group correspondence, the second group correspondence and the third group correspondence may be applied to a second group of terminal devices, some terminal devices in the second group of terminal devices may use the correspondence between the first group to determine which resources to send and receive pilot signals, some terminal devices may use the correspondence between the second group to determine which resources to send and receive pilot signals, and some terminal devices may use the correspondence between the third group to determine which resources to send and receive pilot signals, and so on.

[0109] In some embodiments, when the first information is used to indicate a correspondence between multiple groups, the first information may further include a group number for each group's correspondence in the multiple group correspondence in order to facilitate the distinction between different group correspondences. In some embodiments, the group number for each group's correspondence can uniquely identify that group's correspondence.

[0110] In some embodiments, when the first information is used to indicate the correspondence between multiple groups, the base station can further notify the terminal device of the correspondence between one group corresponding to the terminal device. In one embodiment, the base station can notify the terminal device of the group number of the correspondence between one group corresponding to the terminal device.

[0111] In other words, in some embodiments, the method according to the embodiments of the present invention may further include the step of a terminal device receiving a first signaling, the first signaling being used to indicate a group number of a correspondence of a group used by the terminal device.

[0112] In some embodiments, the first signaling is transmitted by a base station to a terminal device.

[0113] The embodiments of this application do not specifically limit the first signaling; for example, the first signaling may be a dedicated signaling. Alternatively, the first signaling may be a higher-layer signaling (e.g., RRC signaling), a medium access control element (MAC CE) signaling, downlink control information (DCI), etc.

[0114] As described above, when the first information is used to indicate a correspondence between one group, all terminal devices in that group can determine which resources to send and receive pilot signals using the same group correspondence. However, the embodiments of the present invention are not limited thereto, and in some embodiments, when the first information is used to indicate a correspondence between multiple groups, all terminal devices in a group of terminal devices can determine which resources to send and receive pilot signals using the same group correspondence.

[0115] In some embodiments, for example, in a positioning scenario, both the serving cell and the neighboring cell need to determine which resource will send and receive a pilot signal. Therefore, in order to determine which resource will send and receive a pilot signal based on the first information, both the serving cell and the neighboring cell need to know the first information. Based on this, in some embodiments, the base station needs to transmit the first information to the positioning equipment in the core network (e.g., LMF) so that the positioning equipment in the core network can transmit the first information to the neighboring cell.

[0116] In some embodiments, the first information transmitted by the base station to the positioning equipment in the core network may include one or more pieces of information from the following: a correspondence between one or more beam scanning directions and one or more time-domain positions; a correspondence between one or more beam scanning directions and one or more pilot resources; a terminal equipment identifier; and a group number for a correspondence of a group corresponding to a terminal equipment.

[0117] In some embodiments, positioning equipment in the core network can transmit first information to adjacent cells of terminal equipment. The first information transmitted by the positioning equipment in the core network to adjacent cells may include one or more pieces of information, such as the correspondence between one or more beam scanning directions and one or more time-domain positions, the correspondence between one or more beam scanning directions and one or more pilot resources, terminal equipment identifiers, and group numbers of correspondences for a group corresponding to terminal equipment.

[0118] As mentioned above, in some embodiments, the base station can configure pilot resources for terminal equipment. This will be explained in detail below with reference to Figure 6.

[0119] Figure 6 is a flowchart of a wireless communication method according to another embodiment of the present application. The method shown in Figure 6 may include steps S610 and S620.

[0120] In step S610, the terminal device receives first configuration information. The first configuration information may be used to configure one or more of the following: one or more pilot resources, information on the number of pilot beams to actually transmit, and information on the number of pilot resources.

[0121] For example, the first configuration information may be used to constitute one or more pilot resources (resources). In other words, the first configuration information may be used to constitute a resource set, which may include one or more pilot resources. Alternatively, the first configuration information may be used to constitute one or more resource sets, which may include one or more pilot resources.

[0122] For example, the first configuration information may be used to configure one or more pilot resources, information on the number of pilot beams to be actually transmitted, and information on the number of pilot resources. As an example, the first configuration information indicates that five pilot resources can be configured and that the number of pilot beams to be actually transmitted is three. That is, the terminal device can then actually transmit pilot beams (e.g., first pilot signals) using some of the resources in the pilot resources configured by the first configuration information.

[0123] For example, the first configuration information may be used to configure one or more pilot resources, information on the number of pilot beams to be actually transmitted, and information on the number of pilot resources.

[0124] In some embodiments, the number of pilot resources may be the number of pilot resources configured on the terminal device by the network side. In some embodiments, the number of pilot resources may be the number of pilot resources required for the terminal device to actually transmit pilot signals, etc.

[0125] In some embodiments, the first pilot signal is determined based on first information and first configuration information. For example, the first pilot signal is determined based on pilot resources configured by the first information and the first configuration information. Alternatively, the first pilot signal is determined based on pilot resources configured by the first information and the first configuration information, and information on the number of pilot beams actually transmitted, configured by the first configuration information. Alternatively, the first pilot signal is determined based on pilot resources configured by the first information and the first configuration information, information on the number of pilot beams actually transmitted, configured by the first configuration information, and information on the number of pilot resources configured by the first configuration information.

[0126] In some embodiments, if the number of beam scanning directions indicated by the first information is n, and the number of pilot resources configured by the first configuration information is m, then the number j of the beam scanning direction corresponding to the i-th pilot resource in the pilot resources configured by the first configuration information is as follows: j = i * floor (n / m) Here, m and n are positive integers, i is a positive integer less than or equal to m, and floor indicates truncation.

[0127] Naturally, the embodiments of this application are not limited thereto. For example, if the number of beam scanning directions indicated by the first information is n, and the number of pilot resources configured by the first configuration information is m, then the number j of the beam scanning direction corresponding to the i-th pilot resource in the pilot resources configured by the first configuration information is as follows: j = i * ceiling (n / m) Here, m and n are positive integers, i is a positive integer less than or equal to m, and ceiling indicates rounding up.

[0128] In some embodiments, the first configuration information may be transmitted from the base station. That is, the base station can configure one or more pilot resources for the terminal equipment.

[0129] In some embodiments, the first configuration information may be transmitted from a positioning device (e.g., an LMF) in the core network. That is, the positioning device in the core network can configure one or more pilot resources for the terminal device.

[0130] In some embodiments, one or more pilot resources configured by the first configuration information correspond to (or are associated with) one or more beam scanning directions. That is, one or more pilot resources configured by the first configuration information may be resources in different beam scanning directions, or one or more pilot resources configured by the first configuration information may be used to send and receive pilot signals in different beam scanning directions.

[0131] In embodiments of the present invention, positioning equipment in a base station or core network can configure resources in different beam scanning directions for terminal equipment, thereby advantageous for terminal equipment to select appropriate resources based on the subsequently determined beam scanning direction to send and receive pilot signals.

[0132] In some embodiments, the statement that one or more pilot resources configured by the first configuration information correspond to one or more beam scanning directions may mean that one or more pilot resources configured by the first configuration information correspond one-to-one with one or more beam scanning directions.

[0133] In some embodiments, the statement that one or more pilot resources configured by the first configuration information correspond to one or more beam scanning directions may mean that there is a one-to-many or many-to-one correspondence between one or more pilot resources configured by the first configuration information and one or more beam scanning directions.

[0134] In step S620, the terminal device transmits and receives a first pilot signal. The resource that transmits and receives the first pilot signal is determined based on the first information.

[0135] For a detailed explanation of step S620, please refer to the previously mentioned explanation of the relationship between step S310 and the first information. For brevity, it will not be explained again here.

[0136] In some embodiments, one or more pilot resources configured on terminal equipment by a base station may be configured arbitrarily, and in this way, a certain resource configuration may become idle for subsequent devices, leading to resource waste. An example is shown below with reference to Figure 7, where, as shown in Figure 7, a base station configures multiple resources on terminal equipment, and subsequent terminal equipment selects some of the configured resources to transmit pilot signals. However, the number of pilot signals that the terminal equipment actually needs to transmit is less than the number of configured resources, and therefore, unused resources become idle, leading to resource waste, and resources configured in the beam scanning direction corresponding to the dashed box in Figure 7 may be wasted.

[0137] Based on this, in some embodiments, one or more pilot resources configured by the first configuration information may be configured based on one or more of the following: statistical information for terminal devices and positioning information for terminal devices.

[0138] The embodiments of this application do not specifically limit the content of statistical information for terminal equipment. For example, the content of statistical information for terminal equipment may include one or more of the following: statistical information on the beam scanning width for terminal equipment, statistical information on the beam scanning direction for terminal equipment, etc.

[0139] The embodiments of this application do not specifically limit the source of statistical information for terminal equipment. For example, statistical information for terminal equipment may be provided to a base station by a positioning device (e.g., LMF) in the core network.

[0140] The embodiments of this application do not specifically limit the content of the positioning information of the terminal device. For example, it may be approximate location information (simplified positioning information) indicating the approximate location of the terminal device.

[0141] The embodiments of this application do not specifically limit the origin of the positioning information of a terminal device. For example, the positioning information of the terminal device may be provided to a base station by a positioning device in the core network (e.g., LMF). For example, for positioning services or positioning traffic that are not sensitive to latency, a positioning device in the core network may provide a simplified positioning information of the terminal device to a base station, thereby constituting one or more pilot resources used by the base station to send and receive pilot signals based on that information.

[0142] In some embodiments, if the terminal equipment is a low-power UE, the base station can configure one or more pilot resources for the terminal equipment based on the above configuration method. Thus, when the terminal equipment does not access a cell, it does not need to transmit or receive pilot signals in a beam scanning manner, thereby saving time-frequency resources and power consumption of the terminal equipment.

[0143] In some embodiments, in a positioning scenario, the serving cell and adjacent cells can perform multiple position detections (or update the terminal device's location) based on one or more pilot resources configured in the terminal device, and the one or more pilot resources configured are determined based on the terminal device's positioning information (location).

[0144] In some embodiments, after a base station configures one or more pilot resources based on the positioning information of a terminal device, the terminal device can sequentially send and receive pilot signals using the configured one or more pilot resources. For example, after a terminal device sends one pilot signal using one of the configured pilot resources, it can send a second pilot signal using another resource from the configured one or more pilot resources after a certain interval. In some embodiments, when a terminal device enters a connected state, it can sequentially send and receive pilot signals using one or more configured pilot resources. For example, after sending one pilot signal using one of the configured pilot resources, it can enter a connected state and send a second pilot signal using another resource from the configured one or more pilot resources, the configuration of the second pilot signal is determined by a positioning device in the core network (e.g., LMF) based on the positioning results of the first pilot signal, and the pilot signal has more accurate directionality.

[0145] In some embodiments, the direction in which a pilot signal needs to be transmitted and received can be determined based on the direction of a downlink pilot signal detected by the terminal device before the terminal device transmits or receives a pilot signal (e.g., a first pilot signal). This is because if the terminal device can detect a downlink pilot signal in a certain direction, the base station upstream in that corresponding direction will transmit and receive a signal, and the terminal device will receive the signal transmitted by that base station, so the terminal device can continue to transmit and receive signals in that corresponding direction.

[0146] In one embodiment, the terminal equipment can detect downlink pilot signals, for example, by detecting all possible sequences, times, and directions of downlink pilot signals, and then determining the transmission direction of the pilot signals that need to be transmitted based on the detection results, or determining the reception direction of the pilot signals that need to be received based on the detection results.

[0147] The embodiments of this application do not limit the type of downlink pilot signal detected by the terminal equipment. For example, the downlink pilot signal may be one or more signals from SSB, CSI-RS, and CRS. Here, if the downlink pilot signal is SSB, it may be a primary synchronization signal (PSS), a secondary synchronization signal (SSS), etc.

[0148] In some embodiments, the detection of a downlink pilot signal by a terminal device may be equivalent to the detection of the direction of reception of the downlink pilot signal. For example, the terminal device may obtain the direction of reception of the downlink pilot signal using methods such as receiving beam scanning or direction estimation.

[0149] In one embodiment, the beamwidth of the resource transmitting and receiving the first pilot signal is adjustable. In one embodiment, the base station can notify terminal equipment (e.g., broadcast notification, upper-layer signaling notification) that the beamwidth of the resource for the first pilot signal can be adjusted. In another embodiment, the protocol can predefine that the beamwidth of the resource for the first pilot signal is adjustable.

[0150] In some embodiments, if the beamwidth of the resource transmitting and receiving the first pilot signal is adjustable, the base station can further notify terminal equipment of the beamwidth of the resource for the first pilot signal. For example, the base station can notify terminal equipment of the beamwidth of the resource for the first pilot signal using various methods such as broadcast signaling, higher-level signaling, and lower-level signaling.

[0151] In some embodiments, after the transmit and receive beams between the terminal device and the base station are aligned, if there is a direct wave, the terminal device and the base station can detect the signal between them.

[0152] In some embodiments, if there is a non-direct wave after the transmit and receive beams between the terminal equipment and the base station have aligned, the signal transmission and reception quality between the terminal equipment and the base station may be poor because the angle of arrival of the non-direct wave relative to the angle of arrival of the direct wave may be extended within a certain range. Therefore, in some embodiments, if there is a non-direct wave, the signal receiving side (e.g., the base station) can improve the signal transmission and reception quality by performing one or more of the following processes.

[0153] Process 1: The signal receiving side can perform beam scanning within a certain range of the arrival angle based on the arrival time of the direct wave. In this case, the embodiment of the present invention can accurately determine the received beam by performing beam scanning over a narrow range.

[0154] Process 2: The signal receiving side can increase the angle of the receiving beam, thereby allowing the receiving beam to cover indirect waves.

[0155] Process 3: The signal receiver can increase the angle of the receiving beam, thereby allowing the receiving beam to cover indirect waves, and the signal receiver further reduces the beam width within the scanned beam for beam scanning. The receiving beam determined by the method of Process 3 is more accurate than the receiving beam determined by the method of Process 2.

[0156] Having explained the above, for the sake of easier understanding, the overall process of the method of the embodiment of the present application will now be illustrated with reference to Figure 8. In the example in Figure 8, the case where the first pilot signal is SRS will be used as an example. The method shown in Figure 8 may include steps S810 to S850.

[0157] In step S810, the terminal device receives one or more SRS resources configured by the network. In other words, the terminal device receives a set of SRS resources configured by the network.

[0158] In some embodiments, the one or more SRS resources consist of base stations. In some embodiments, the one or more SRS resources consist of positioning equipment in the core network.

[0159] In some embodiments, for one or more SRS resources, the beam scanning direction corresponding to each SRS resource, and / or the correspondence between the beam scanning direction and the time-domain position corresponding to each resource, can be indicated to terminal equipment by first information. For example, the base station may indicate this to terminal equipment by broadcast signaling, RRC signaling, or as predefined by a protocol.

[0160] In step S820, the terminal equipment detects the downlink pilot signal. For example, the terminal equipment detects SSB, CSI-RS, CRS, etc.

[0161] In some embodiments, terminal equipment can detect downlink pilot signals in all possible sequences, for all possible times, and in all possible directions.

[0162] In some embodiments, terminal equipment detects a downlink pilot signal to determine the direction of signal reception, for example, to determine the direction of SSB reception and the direction of CSI-RS reception. In this way, terminal equipment can determine in which direction the base station is transmitting and receiving signals.

[0163] In step S830, the terminal device determines which SRS to transmit based on the detection results.

[0164] For example, the terminal device determines, based on the detection results, which beam scanning direction it can transmit the SRS in.

[0165] In some embodiments, the number of SRS resources required for the terminal device to actually transmit SRS may be less than the number of configured SRS resources.

[0166] In step S840, for the SRS to be transmitted, the terminal device determines the time-domain position for transmitting the SRS based on the direction of the detected downlink pilot signal and the first information.

[0167] For example, if a terminal device determines that it needs to transmit an SRS in the 30° direction based on the direction of the detected downlink pilot signal, the terminal device can determine at which time-domain position to transmit the SRS in the 30° direction based on the correspondence between the beam scanning direction and the time-domain position indicated by the first information.

[0168] In step S850, the terminal device transmits an SRS.
