Description

Technical Field

[0001] This application relates to the field of wireless communication, and more specifically, to a measurement method and a communication device. Background Technology

[0002] In current communication systems, network devices periodically transmit common signals (also known as always-transmitted common signals) to facilitate terminal identification and access. However, this frequent and periodic transmission of common signals results in significant overhead for network equipment. To address this, Release 19 (R19) of the 3rd Generation Partnership Project (3GPP) began researching network energy saving (NES), proposing the introduction of adaptive processing of common signals for certain cells to achieve energy savings.

[0003] The R19 NES discussion includes enhancements in three areas: on-demand SSB (OD-SSB), on-demand SIB1 (OD-SIB1), and adaptation of common signal / channel transmissions. On-demand SSB primarily targets secondary cells (SCells) of connected terminal equipment configured with carrier aggregation (CA). SCells transmit SSBs on demand for network energy conservation.

[0004] However, the UE's measurement capabilities are limited. How the UE can perform on-demand SSB and other measurement targets when on-demand SSB transmission begins is an urgent problem to be solved. Summary of the Invention

[0005] This application provides a measurement method and a communication device, providing a process for measuring serving cells on-demand SSBs.

[0006] Firstly, a measurement method is provided. This method can be applied to the terminal side; that is, it can be executed by the terminal device or by components of the terminal device (such as a chip, chip system, circuit, or communication module). This application does not limit the scope of the method. The following description mainly uses a terminal device as an example.

[0007] The method may include: receiving first indication information, the first indication information being used to indicate priority measurement of on-demand SSB; and, according to the first indication information, prioritizing measurement of the on-demand SSB.

[0008] Based on the above scheme, if the terminal device does not promptly measure the on-demand SSB after the base station sends it, the measurement delay of the on-demand SSB will be significant. For example, if the terminal device only starts measuring the on-demand SSB after completing measurements of other targets, the SCell activation delay will increase, which in turn increases the time it takes for the base station to send the on-demand SSB, thus increasing the base station's energy consumption. According to the above measurement method, before sending the on-demand SSB, the network device instructs the terminal device to prioritize measuring the on-demand SSB, enabling the terminal device to quickly complete the on-demand SSB measurement and saving the energy consumed by the base station in sending the on-demand SSB.

[0009] In some implementations, prioritizing the measurement of the on-demand SSB includes: first measuring the on-demand SSB, and then measuring other measurement targets besides the on-demand SSB.

[0010] Based on the above scheme, after receiving the first instruction information, the terminal device directly measures the on-demand SSB.

[0011] In some implementations, prioritizing the measurement of the on-demand SSB further includes: receiving the measurement order of the on-demand SSB; and prioritizing the measurement of the on-demand SSB when the measurement order of the on-demand SSB is greater than or equal to the measurement order of the other measurement targets, wherein the measurement order is used to indicate a recommended order for measuring the measurement targets.

[0012] Based on the above scheme, after receiving the first instruction information, the terminal device directly measures the on-demand SSB regardless of whether the measurement order of other measurement targets is before the on-demand SSB.

[0013] In some implementations, the step of prioritizing the measurement of the on-demand SSB according to the first indication information includes: prioritizing the measurement of the on-demand SSB upon receiving second indication information, wherein the second indication information indicates the on-demand SSB transmission of one or more serving cells.

[0014] Based on the above scheme, after receiving the instruction to start sending on-demand SSB, the terminal device begins to prioritize measuring on-demand SSB.

[0015] In some implementations, when the second indication information indicates that multiple serving cells are sending on-demand SSBs, the priority measurement of the on-demand SSBs includes: measuring the on-demand SSBs of each of the multiple serving cells sequentially according to the order of the multiple serving cells.

[0016] In some implementations, when the second indication information indicates that on-demand SSBs of multiple serving cells are sent, the method further includes: receiving the measurement order corresponding to each of the multiple serving cells; the priority measurement of the on-demand SSB includes: measuring the on-demand SSBs of the multiple serving cells sequentially according to the measurement order corresponding to each of the multiple serving cells.

[0017] In some implementations, the method further includes sending the measurement results of the on-demand SSB.

[0018] In some implementations, the method further includes receiving third indication information, the third indication information being used to instruct the on-demand SSB to stop transmitting.

[0019] Secondly, a measurement method is provided. This method can be applied to the network side; that is, it can be executed by a network device or by a component of the network device (such as a chip, chip system, circuit, or communication module). This application does not limit the scope of the method. The following description mainly uses a network device as an example.

[0020] The method may include: sending a first indication message, the first indication message being used to indicate priority measurement of on-demand synchronization signal blocks (SSBs).

[0021] In some implementations, the method further includes: sending a second indication message, the second indication message instructing one or more serving cells to send on-demand SSBs.

[0022] In some implementations, where the second indication information indicates on-demand SSB transmission for multiple serving cells, the method further includes: transmitting the measurement sequence corresponding to each of the multiple serving cells, the measurement sequence being used to indicate a recommended order for measuring the measurement target.

[0023] In some implementations, the method further includes receiving the measurement results of the on-demand SSB.

[0024] In some implementations, the method further includes sending a third indication message, the third indication message being used to instruct the on-demand SSB to stop sending.

[0050] The technical solutions in this application will now be described with reference to the accompanying drawings.

[0051] Before introducing the scheme of this application, the following points should be noted.

[0052] (1) In this application, "instruction" can include direct instruction, indirect instruction, explicit instruction, implicit instruction, etc. When describing an instruction information as indicating A, it can be understood that the instruction information carries A, carries the identifier of A, carries B which is associated with A, carries the identifier of B which is associated with A, etc. In other words, if the receiving side of an instruction information can determine A based on the instruction information, it can be described as the instruction information indicating A, and the specific method of determination is not limited. When it is understood that the instruction information carries A, "instruction" can be replaced with "includes". In this case, a statement such as "send / receive instruction information, the instruction information indicates A" can be replaced with "send / receive A".

[0053] In this application, the information indicated by the instruction information is called the information to be instructed. In specific implementations, there are many ways to indicate the information to be instructed, such as, but not limited to, directly indicating the information to be instructed, such as the information to be instructed itself or its index. It can also indirectly indicate the information to be instructed by indicating other information, where there is a relationship between the other information and the information to be instructed. It can also indicate only a part of the information to be instructed, while the other parts are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing instruction overhead to some extent. Furthermore, the information to be instructed can be sent as a whole or divided into multiple sub-information pieces, and the sending period and / or timing of these sub-information pieces can be the same or different.

[0054] (2) In this application, the expression " / " is used to indicate that the objects before and after are in an "or" relationship; for example, A / B can mean: A or B. The expression "and / or" is used to indicate that the objects before and after are in a relationship of either "and" or "or"; for example, A and / or B can mean the following: A exists alone, B exists alone, A and B exist simultaneously, where A and B can be single or multiple. "At least one of the following" or similar expressions are used to indicate any combination of the listed items; for example, at least one of A, B and / or C can mean the following: A exists alone, B exists alone, C exists alone, A and B exist simultaneously, B and C exist simultaneously, A and C exist simultaneously, A, B and C exist simultaneously, where A, B, and C can be single or multiple.

[0055] (3) In this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include direct transmission via the air interface or indirect transmission by other units or modules via the air interface. "Receive information from YY" can be understood as the source of the information being YY, which may include direct reception from YY via the air interface or indirect reception from YY by other units or modules via the air interface. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface. In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via a bus, wiring, or interface.

[0056] (4) In the various embodiments of this application, unless otherwise specified or in case of logical conflict, the terms and / or descriptions of different embodiments are consistent and can be referenced by each other. The technical features of different embodiments can be combined to form new embodiments according to their inherent logical relationship.

[0057] (5) In this application, "first," "second," and "#1," "#2," and "#A" are merely for descriptive convenience and are used to distinguish objects, and are not intended to limit the scope of the embodiments of this application. They are not used to describe the order or sequence of features. It should be understood that such described objects can be interchanged where appropriate in order to describe solutions other than those in the embodiments of this application.

[0058] (6) In this application, the words “exemplary,” “for example,” etc., are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as an “example” in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of the word “example” is intended to present the concept in a concrete manner. In the embodiments of this application, “of,” “corresponding, relevant,” and “corresponding” may sometimes be used interchangeably, and it should be noted that their intended meanings are consistent unless their distinction is emphasized.

[0059] First, let me introduce the communication system to which this application applies.

[0060] The technical solutions provided in this application can be applied to various communication systems, such as 5th generation (5G) or new radio (NR) systems, long term evolution (LTE) systems, LTE frequency division duplex (FDD) systems, and LTE time division duplex (TDD) systems. The technical solutions provided in this application can also be applied to future communication network systems. Furthermore, the technical solutions provided in this application can be applied to device-to-device (D2D) communication, vehicle-to-everything (V2X) communication, machine-to-machine (M2M) communication, machine-type communication (MTC), and Internet of Things (IoT) communication systems. The technical solutions provided in this application can also be applied to non-terrestrial network (NTN) systems such as inter-satellite communication and satellite communication.

[0061] As an example, a satellite communication system includes a satellite base station and terminal equipment. The satellite base station provides communication services to the terminal equipment. Satellite base stations can also communicate with each other. A satellite can act as a base station or as a terminal device. Here, "satellite" can refer to drones, hot air balloons, low-Earth orbit satellites, medium-Earth orbit satellites, high-Earth orbit satellites, etc. "Satellite" can also refer to non-terrestrial base stations or non-terrestrial equipment.

[0062] As an example, V2X communication can include: vehicle-to-vehicle (V2V) communication, vehicle-to-infrastructure (V2I) communication, vehicle-to-pedestrian (V2P) communication, and vehicle-to-network (V2N) communication.

[0063] In a communication system, a device can send signals to or receive signals from another device. These signals can include information, signaling, or data. The device can also be replaced by an entity, network entity, communication equipment, communication module, node, communication node, etc. This application uses a device as an example for description.

[0064] The terminal device in this application embodiment can be a device or module that accesses the aforementioned communication system and has corresponding communication functions. The terminal device can include various devices with wireless communication capabilities, which can be used to connect people, objects, machines, etc. The terminal device can be widely applied in various scenarios, such as: cellular communication, D2D, V2X, peer-to-peer (P2P), M2M, MTC, IoT, virtual reality (VR), augmented reality (AR), industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, drones, robots, remote sensing, passive sensing, positioning, navigation and tracking, autonomous delivery, etc. The terminal device can be a terminal in any of the above scenarios, such as an MTC terminal, an IoT terminal, etc. Terminal equipment can be user equipment (UE), terminal, fixed equipment, mobile station equipment or mobile equipment, subscriber unit, handheld device, vehicle-mounted equipment, wearable device, cellular phone, smartphone, session initiation protocol (SIP) phone, wireless data card, personal digital assistant (PDA), computer, tablet computer, laptop computer, wireless modem, handset, laptop computer, computer with wireless transceiver capability, smart book, vehicle, satellite, global positioning system (GPS) device, target tracking device, aircraft (e.g., drone, helicopter, multiple helicopters, four helicopters, or airplanes), ship, remote control device, smart home device, industrial equipment, transportation vehicle with wireless communication capability, communication module, or roadside unit with terminal function, all conforming to the 3GPP standard. The device may be a wireless communication unit (RSU), or a device built into the aforementioned device (e.g., a communication module, modem, or chip in the aforementioned device), or other processing devices connected to the wireless modem.

[0065] It should be understood that in certain scenarios, a UE can also be used as a base station. For example, a UE can act as a scheduling entity, providing sidelink signaling between UEs in scenarios such as V2X, D2D, or P2P.

[0066] In this embodiment, the device for implementing the functions of a terminal device, i.e., the terminal device, can be the terminal device itself, or it can be any device capable of supporting the terminal device in implementing the functions, such as a chip system, chip, circuit, or communication module (i.e., a communication module that performs communication functions). This device can be installed in the terminal device. In this embodiment, the chip system can be composed of chips, or it can include chips and other discrete devices. Furthermore, the device can also be configured with program instructions for performing corresponding communication functions.

[0067] The network device in this application embodiment can be a device or module with corresponding communication functions. The network device can be a device used to communicate with terminal devices; it can also be called an access network device or a wireless access network device, such as a base station. In this application embodiment, the network device can refer to a radio access network (RAN) node (or device) that connects the terminal device to the wireless network. A base station can broadly encompass, or be replaced by, various names including: NodeB, evolved NodeB (eNB), next-generation NodeB (gNB), relay station, access point, transmitting and receiving point (TRP), transmitter, master station, auxiliary station, multiple standard radio (MSR) node, home base station, network controller, access node, wireless node, access point (AP), transmission node, transceiver node, baseband unit (BBU), remote radio unit (RRU), active antenna unit (AAU), remote radio head (RRH), central unit (CU), distributed unit (DU), positioning node, etc. A base station can be a macro base station, micro base station, relay node, donor node, or similar, or a combination thereof. A base station can also refer to a communication module, modem, or chip installed within the aforementioned equipment or apparatus. A base station can also be a mobile switching center, a device that performs base station functions in D2D, V2X, and M2M communications, a network-side device in future communication networks, or a device that performs base station functions in future communication systems. A base station can support networks using the same or different access technologies. The embodiments of this application do not limit the specific technologies or device forms used in the network equipment.

[0068] Base stations can be fixed or mobile. For example, a helicopter or drone can be configured to act as a mobile base station, and one or more cells can move depending on the location of the mobile base station. In other examples, a helicopter or drone can be configured as a device to communicate with another base station.

[0069] In some deployments, the network devices mentioned in the embodiments of this application may be devices including CU, or DU, or devices including CU and DU, or devices with control plane CU nodes (central unit-control plane (CU-CP)) and user plane CU nodes (central unit-user plane (CU-UP)) and DU nodes.

[0070] In some deployments, multiple RAN nodes collaborate to assist terminal devices in achieving wireless access, with different RAN nodes each implementing some of the base station's functions. For example, RAN nodes can be CUs, DUs, CU-CPs, CU-UPs, or radio units (RUs). CUs and DUs can be configured separately or included in the same network element, such as a BBU. RUs can be included in radio equipment or radio units, such as RRUs, AAUs, or RRHs.

[0071] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, a radio access network can also be an open radio access network (O-RAN) architecture. In an O-RAN system, CU can also be called an open CU (open CU, O-CU), DU can also be called an open DU (open DU, O-DU), CU-CP can also be called an open CU-CP (O-CU-CP), CU-UP can also be called an open CU-UP (O-CU-UP), and RU can also be called an open RU (open RU, O-RU). Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software modules and hardware modules.

[0072] In this embodiment, the device for implementing the functions of a network device can be a network device itself, or a device capable of supporting the network device in implementing those functions, such as a chip system, chip, circuit, or communication module (i.e., a communication module that performs communication functions). This device can be installed within the network device. In this embodiment, the chip system can be composed of chips, or it can include chips and other discrete devices. Furthermore, the device can be configured with program instructions for performing corresponding communication functions. This embodiment only uses a network device as an example to illustrate the device for implementing the functions of a network device, and does not limit the solution of this embodiment.

[0073] Network devices and terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can also be deployed in the air on airplanes, balloons, and satellites. This application does not limit the scenario in which the network devices and terminal devices are located.

[0074] Combination Figure 1 The communication system applicable to the embodiments of this application is briefly described below.

[0075] Figure 1 This is a schematic diagram of a wireless communication system applicable to embodiments of this application. For example... Figure 1 As shown, the wireless communication system includes a wireless access network 100. The wireless access network 100 can be a next-generation (e.g., future or later) wireless access network, or a traditional (e.g., 5G, 4G, 3G, or 2G) wireless access network. One or more terminal devices (120a-120j, collectively referred to as 120) can be interconnected or connected to one or more network devices (110a, 110b, collectively referred to as 110) within the wireless access network 100. Network elements in the wireless communication system are connected via interfaces (e.g., NG, Xn) or over-the-air interfaces.

[0076] When network devices and terminal devices communicate, the network device can manage one or more cells, and a cell can include at least one terminal device. A cell can be understood as an area within the wireless signal coverage range of the network device.

[0077] Figure 1 This is just an illustration; the wireless communication system may also include other devices, such as core network equipment, wireless relay equipment, and / or wireless backhaul equipment. Figure 1 It is not shown in the middle.

[0078] Figure 2 This is another schematic diagram of a wireless communication system applicable to embodiments of this application. This wireless communication system may also be referred to as an ORAN system, for example. The wireless communication system may include a core network, access network equipment, and a UE. As an example, the wireless communication system may also include... Figure 2Other components besides those shown are not specifically limited in this application.

[0079] Access network equipment can communicate with the core network (CN) via a backhaul link. Access network equipment can also communicate with the UE via an air interface. Specifically, the BBU in the access network equipment communicates with the core network via a backhaul link. The RU in the access network equipment communicates with at least one UE via an air interface. The BBU communicates with at least one RU via a fronthaul link; the BBU and RU may or may not be co-located. A BBU includes at least one CU and at least one DU, and the CU and DU can communicate via at least one midhaul link.

[0080] See Figure 3 As an example, Figure 3 This is a schematic diagram of an access network device applicable to embodiments of this application.

[0081] Optionally, the access network equipment includes a CU. The CU is a logical node that carries the radio resource control (RRC), service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer, and other control functions of the access network equipment. The CU can connect to network nodes such as the core network through interfaces, such as the E2 interface. The CU may have some core network functions. The CU (e.g., the PDCP layer and / or higher) connects to the DU (e.g., the radio link control (RLC) layer and lower layers of the DU) through interfaces, such as the F1 interface. Optionally, the F1 interface can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transmission, etc.). F1AP is the application protocol of the F1 interface, defining the signaling procedures of F1 in some examples. The F1 interface supports control plane F1-C and user plane F1-U.

[0082] As an example, a CU includes CU-CP and CU-UP. CU-CP is a logical node carrying the control plane (PDCP-C) layer, which carries the RRC layer and the Packet Data Convergence Protocol layer, and is used to implement the CU's control plane functions. CU-CP can interact with network elements in the core network used to implement control plane functions. These network elements in the core network can be access and mobility function (AMF) network elements, such as the access and mobility management function (AMF) in a 5G system. The AMF network element is responsible for mobility management in the mobile network, such as terminal device location updates, terminal device registration with the network, and terminal device handover. CU-UP is a logical node carrying the user plane (PDCP-U) layer, which carries the SDAP layer and the Packet Data Convergence Protocol layer, and is used to implement the CU's user plane functions. CU-UP can interact with network elements in the core network used to implement user plane functions. These network elements in the core network, such as the user plane function (UPF) in a 5G system, are responsible for data forwarding and receiving in terminal devices. The above CU and DU configurations are merely examples. In practical applications, the functions of the CU and DU can be configured as needed. For instance, the CU or DU can be configured to have more protocol layer functions, or to have only some protocol layer processing functions. For example, some RLC layer functions and protocol layer functions above the RLC layer can be placed in the CU, while the remaining RLC layer functions and protocol layer functions below the RLC layer can be placed in the DU. Furthermore, the functions of the CU or DU can be divided according to service type or other system requirements. For example, based on latency, functions that require low latency can be placed in the DU, while functions that do not require low latency can be placed in the CU.

[0083] Optionally, the access network equipment includes a DU. For example... Figure 3 As shown, a DU is a logical node that carries the RLC layer, medium access control (MAC) layer, higher physical layer (Higher PHY) layer, and other functions. In some examples, a DU can control at least one RU. The DU connects to the RU through interfaces, which can be fronthaul interfaces. In some examples, the Higher PHY layer includes the PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation, and demodulation.

[0084] Optionally, the access network equipment includes a RU. For example... Figure 4 As shown, the RU is a logical node that carries both lower physical layer (Lower PHY) and radio frequency (RF) processing. In some examples, the RU can be a 3GPP transmission reception point (TRP), a remote radiohead (RRH), or other similar entities. In some examples, the Lower PHY includes PHY processing functions such as Fast Fourier Transform (FFT), Inverse Fast Fourier Transform (IFFT), digital beamforming, and filtering. The RU communicates with one or more UEs via a radio link (such as an RF chain).

[0085] The DU and RU can be co-located or not. The DU and RU exchange control plane and user plane information via a fronthaul link through a lower-layer split CUS-plane (LLS-CUS-Plane) (or O-RANCUS-Plane) interface. Here, CUS-Plane represents the control plane (C-Plane), user plane (U-Plane), and synchronization plane (S-Plane) (CUS-Plane). LLS-CUS may include a lower-layer split control (LLS-C) interface providing the control plane and a lower-layer split user (LLS-U) interface respectively. Additionally, LLS-CUS may include a lower-layer split synchronization (LLS-S) interface providing the synchronization plane. In some examples, the control plane (or control plane) refers to the real-time control between the DU and RU. The DU and RU exchange management plane information via the lower-layer split management (LLS-M) interface of the fronthaul link. The management plane (M-Plane) refers to the non-real-time management operations between the DU and RU.

[0086] DU and RU can cooperate to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of DU and RU can be configured in various ways depending on the design. For example, a DU can be configured to implement baseband functions, and an RU can be configured to implement mid-RF functions. Another example is that a DU can be configured to implement higher-level functions in the PHY layer, and an RU can be configured to implement lower-level functions in the PHY layer, or to implement both lower-level and RF functions. Higher-level functions in the physical layer can include a portion of the physical layer's functions that are closer to the MAC layer, while lower-level functions in the physical layer can include another portion of the physical layer's functions that are closer to the mid-RF side.

[0087] The above Figures 1 to 3 For illustrative purposes only, the embodiments described in this application are not limited thereto.

[0088] To facilitate understanding of the embodiments of this application, a brief explanation of the background and terminology involved in this application is provided.

[0089] 1. Synchronization signal block (SSB)

[0090] SSB (Standard Signal Broadcast) is a signal continuously broadcast by the base station. Its function is to help the UE discover cells. By searching for the frequency point where the SSB is located, the UE discovers the cell once the SSB signal is found. It is also used for downlink synchronization, allowing the UE to establish frequency synchronization with the base station. Furthermore, the UE can measure the signal quality of the SSB signal to determine the quality of the current cell and whether it meets the cell selection criteria, allowing it to choose this cell as its serving cell. Therefore, SSB is a crucial fundamental signal in the communication process between the base station and the UE.

[0091] As an example, SSB can be used to achieve the following functions: 1) cell synchronization and acquisition of master information block (MIB); 2) network device side beam scanning; 3) layer 1 (L1) or layer 3 (L3) measurement.

[0092] 2. Measurement

[0093] As an example, measurements can be divided into two parts based on the layers involved: physical layer measurements (i.e., layer 1 (L1) measurements) and RRC layer measurements (i.e., layer 3 (L3) measurements). At the physical layer, the terminal device performs specified types of measurements on the configured measurement resources.

[0094] For SSB-based measurements, the terminal device merges the measurement results obtained from multiple SSBs with the same SSB index and PCI to obtain the beam-level layer 1 measurement result of the SSB corresponding to the SSB index of the cell corresponding to the PCI, and reports it to layer 3.

[0095] It is understood that the above measurement process is an example, and the embodiments of this application do not limit the specific measurement method.

[0096] 3. Carrier aggregation (CA)

[0097] Carrier aggregation is a technology that provides additional services to a UE by using a second, third, or more cells to serve the same UE, thereby improving the user experience. CA is limited to the same radio access technology and, most of the time, aggregates different cells under the same macro base station.

[0098] For example, in a CA architecture, the primary cell (PCell) is responsible for transmitting control data to the SCell, and the UE itself does not have a corresponding control link connection with the SCell. That is, the UE and the SCell do not have an RRC connection. In existing technologies, the UE needs to measure the SSBs transmitted by the SCell for uplink / downlink synchronization with the SCell and for L1 or L3 measurements. The SCell does not need to send system broadcast messages; its system broadcast messages are configured to the UE by the PCell via RRC. However, the SCell does need to send SSBs for the UE to perform uplink / downlink synchronization with the SCell and for L1 or L3 measurements.

[0099] 4. Activation of auxiliary cells

[0100] When configuring an SCell for the UE via RRC signaling, the PCell specifies the initial state of the SCell during configuration, sCellstate. If the initial state is active, the SCell is activated immediately. If the initial state is deactivated, the PCell will send a Medium Access Control element (MAC CE) to the UE to activate the corresponding SCell when necessary.

[0101] Figure 4 This is a message format for activating the MAC CE of a secondary cell.

[0102] C1 indicates the activation / deactivation status of SCell 1. A value of 1 indicates that the SCell is activated, and a value of 0 indicates that the SCell is deactivated. Similarly, C2 to C6 indicate the activation / deactivation status of different cells, respectively. R is a reserved bit and is not used.

[0103] 5. On-demand SSB (OD-SSB)

[0104] To enhance network energy efficiency, ongoing R19 standard discussions are exploring the possibility of on-demand transmission of Service Serving (SSBs) on SCells. This means that SSBs on SCells can be transmitted non-periodically, but only when needed. They are transmitted when there is demand and not transmitted when there is no demand, thus achieving network energy savings.

[0105] On-demand SSB delivery is one of the key energy-saving technologies being discussed in the standard, and its potential applications include:

[0106] Scenario 1: The UE is not configured with a SCell by the PCell. In this case, the UE does not need to care about the status of the SCell, and this scenario is excluded.

[0107] Scenario 2: The UE is configured with an SCell by the PCell, but it is not activated. In this case, OD-SSB can be triggered at this stage. The UE can measure the signal status of the SCell and report it to the PCell. If the PCell finds that the signal status of this SCell is not good, the PCell can delete the SCell.

[0108] Scenario 2A: When the UE receives the SCell activation command, the transmission of OD-SSB at this time enables the UE to measure the SCell, obtain the measurement results (which can be the measurement results of the cell or the measurement results of each SSB beam), and perform uplink and downlink synchronization between the UE and the SCell.

[0109] Scenario 3A: After the UE receives the SCell activation command, it can trigger the transmission of OD-SSB during the SCell activation process.

[0110] Scenario 3B: After the UE is successfully activated in the SCell, if the synchronization between the UE and the SCell fails, the UE can trigger OD-SSB, which will cause the base station to start sending SSB to facilitate the synchronization between the UE and the SCell.

[0111] In addition, the standard also discusses two different cases:

[0112] like Figure 5 As shown. Figure 5This is a schematic diagram of a secondary cell OD-SSB provided in an embodiment of this application.

[0113] Case 1: As Figure 5 As shown in (a), there is no periodic SSB on this secondary cell, and the base station will decide to send an SSB as needed.

[0114] When the base station decides to activate the secondary cell, it will send the SCell Activation MAC CE command to the UE.

[0115] Case 2: For example Figure 5 As shown in (b), there is a periodic SSB (called always on SSB, AO-SSB) broadcast on this secondary cell. The base station will decide to send OD-SSB as needed. The transmission period of AO-SSB may be different from that of OD-SSB. For example, in order to save energy for the base station, the transmission period of AO-SSB is long and the transmission period of OD-SSB is short.

[0116] With the introduction of OD-SSB, the measurement mechanism also needs improvement. As described in the background section, the UE's measurement capabilities are limited. A UE can only have a maximum of two radio frequency links for measurement. One radio frequency link needs to measure the cell quality of the PCell. The other radio frequency link needs to measure the cell quality of other cells, such as the cell quality of other SCells, the cell quality of other neighboring cells, inter-frequency measurements, etc. If the UE does not measure the OD-SSB in a timely manner when it starts transmitting, it will result in a large measurement delay. Current terminal-defined measurement metrics have a wide range for delay. For example, in SCell measurements, the required measurement time range is twice the measurement cycle. For instance, if the UE starts measuring the OD-SSB only after completing other measurement targets, it increases the SCell activation delay and also increases the time the base station spends transmitting the OD-SSB, thus increasing the base station's energy consumption.

[0117] The current standard also supports configuring the measurement sequence when configuring measurement targets. Measurement targets with earlier configured measurement sequence indices are measured first, while those with later indices are not. For example, if the measurement sequence for measurement target 1 is 1 and the measurement sequence for measurement target 2 is 2, then the UE will measure measurement target 1 first. When multiple measurement targets have the same measurement sequence, the UE implementation prioritizes measuring one of the targets; that is, the UE measures the targets sequentially according to their configured measurement sequences. However, this measurement mechanism is inflexible for OD-SSB measurements; once RRC configuration is complete, it cannot quickly and dynamically update the measurement sequence for different targets.

[0118] Based on this, this application aims to provide a measurement method that enables the UE to measure the OD-SSB as soon as possible after the base station has finished transmitting the OD-SSB.

[0119] The methods provided by the embodiments of this application will be described in detail below with reference to the accompanying drawings. The embodiments provided by this application can be applied to the scenarios shown in the above figures and are not limited thereto. Furthermore, the terms used below are as explained above and will not be repeated hereafter. For ease of description, terminal devices and network devices are used as examples for illustrative purposes. The terminal device can be replaced by components of the terminal device (e.g., a chip, chip system, circuit, or communication module), and the network device can be replaced by components of the network device (e.g., a chip, chip system, circuit, or communication module). Furthermore, the steps described below as being performed by a single execution entity can also be divided into steps performed by multiple execution entities, which can be logically and / or physically separated.

[0120] Figure 6 This is a schematic diagram of a measurement method 600 provided in an embodiment of this application. Figure 6 The method 600 shown may include the following steps.

[0121] S610 (optional step): The network device sends serving cell configuration information to the terminal device; correspondingly, the terminal device receives the serving cell configuration information.

[0122] For example, the signaling sent by the network device may be an RRC reconfiguration, which includes serving cell configuration information.

[0123] The serving cell configuration information refers to information related to the serving cell configuration. Optionally, the serving cell configuration information includes at least one of the following: serving cell information, measurement configuration information, and one or more sets of on-demand SSB transmission configuration information. Each set of on-demand SSB transmission configuration information corresponds to an index value, which is used to identify the corresponding transmission configuration information.

[0124] The on-demand SSB transmission configuration information may include: on-demand SSB frequency information, on-demand SSB period information, on-demand SSB burst set beam position (ssb-PositionsInBurst), on-demand SSB subcarrier spacing, and on-demand SSB transmission power.

[0125] As an example, measurement configuration information may include the following aspects.

[0126] 1) Measurement object (MO): For example, it can be the frequency information of the on-demand SSB, such as the frequency point or frequency band, the physical cell identifier of the measurement, the measurement period, the measurement time, the measurement sequence, etc.

[0127] The measurement order refers to the recommended order in which different measurement targets are measured. Measurement targets with earlier configured measurement order indices (or smaller index values) are measured first, while those with later configured measurement order indices (or larger index values) are not measured first. For example, if the measurement order for measurement target 1 is 1 and the measurement order for measurement target 2 is 2, then the UE will measure measurement target 1 first.

[0128] 2) Reporting configuration (ReportConfig): In the reporting configuration, the network device informs the terminal device of the details of the specific measurements to be performed. As an example, the reporting configuration includes, but is not limited to: the type of measurement, the method of triggering the reporting, the format of the report, etc.

[0129] Optionally, the RRC reconfiguration also includes a fourth indication of whether the terminal device prioritizes measuring the on-demand SSB.

[0130] For example, if it is indicated that on-demand SSB should be measured first, then the terminal device will measure on-demand SSB first when it receives on-demand SSB.

[0131] For example, if the instruction is not to prioritize measuring on-demand SSB, then the terminal device will not prioritize measuring on-demand SSB when it receives on-demand SSB.

[0132] The fourth indication information can indicate a true or false state. For example, when the fourth indication information indicates a true state, it indicates that the terminal device should prioritize measuring the on-demand SSB; when the fourth indication information indicates a false state, it indicates that the terminal device should not prioritize measuring the on-demand SSB; and vice versa.

[0133] In this application, true can also be replaced with enabled, activated, or other descriptions, and false can also be replaced with disabled, deactivated, or other descriptions. This application does not limit the choice of true.

[0134] Optionally, the network device may indicate only one state through this fourth indication information, such as indicating only priority measurement of on-demand SSB, or only indicating that on-demand SSB is not prioritized.

[0135] For example, network devices only send a fourth indication message indicating a true state when they need to prioritize measuring on-demand SSB; otherwise, they do not send the fourth indication message. Correspondingly, if a terminal device does not receive the fourth indication message, it will not prioritize measuring on-demand SSB by default.

[0136] For example, network devices only send a fourth indication message indicating a false state when they do not need to prioritize measuring the on-demand SSB; otherwise, they do not send the fourth indication message. Correspondingly, terminal devices, if they do not receive the fourth indication message, will prioritize measuring the on-demand SSB by default.

[0137] S620, the network device sends a first indication information to the terminal device, the first indication information being used to indicate priority measurement of on-demand SSB; correspondingly, the terminal device receives the first indication information.

[0138] S630, the network device sends a second indication message to the terminal device, the second indication message instructing one or more serving cells' on-demand SSBs to send; correspondingly, the terminal device receives the second indication message.

[0139] For example, the first indication information can be a 1-bit field indicating whether on-demand SSB is measured first; an indication of 1 indicates that on-demand SSB is measured first; an indication of 0 indicates that on-demand SSB is not measured first. The reverse is also true.

[0140] For example, the second indication information may consist of one or more fields used to indicate the on-demand SSB transmission status of the one or more serving cells. For example, the second indication information may be a field of 1 bit or more bits, where each bit corresponds to a cell. When the value of a bit is 1, it indicates that the on-demand SSB of the cell corresponding to that bit is activated for transmission (or has started transmission), and when the value of a bit is 0, it indicates that the on-demand SSB of the cell corresponding to that bit is deactivated for transmission (or has stopped transmission).

[0141] Optionally, the first indication information and the second indication information can be sent simultaneously and can be carried in the same message, for example, carried in MAC CE.

[0142] Optionally, the network device also sends a fifth indication message to the terminal device. This fifth indication message indicates either the transmission period of the on-demand SSB or the index of the on-demand SSB transmission configuration information. The terminal device can perform measurements on the corresponding on-demand SSB based on either the transmission period or the index of the on-demand SSB transmission configuration information.

[0143] Optionally, the fifth instruction information and the second instruction information are carried in the same message, for example, in a MAC CE.

[0144] Optionally, in step 610, the network device configures the terminal device with a fourth indication message indicating whether to prioritize measuring the on-demand SSB. If the fourth indication message indicates priority measurement of the on-demand SSB, the terminal device, upon receiving the fourth indication message, is configured to prioritize measuring the on-demand SSB. Therefore, after receiving the second indication message, the terminal device will prioritize measuring the on-demand SSB. In other words, even without receiving the first indication message, the terminal device will prioritize measuring the on-demand SSB, without needing the first indication message to instruct the terminal device to prioritize measuring the on-demand SSB.

[0145] Alternatively, if the fourth indication information indicates that on-demand SSB is not measured first, then even if the terminal device receives the first and second indication information, it will not measure on-demand SSB first.

[0146] S640, the network device sends the on-demand SSB; correspondingly, the terminal device measures the on-demand SSB first according to the first instruction information.

[0147] For example, upon receiving the second instruction information, the terminal device prioritizes measuring the on-demand SSB according to the instruction of the first instruction information.

[0148] Alternatively, if the network device configures a fourth indication information for the terminal device in step S610 to prioritize the measurement of on-demand SSB, then the terminal device, upon receiving the second indication information, will prioritize the measurement of on-demand SSB according to the indication of the fourth indication information.

[0149] Among them, the priority measurement of on-demand SSB can be implemented in multiple ways.

[0150] In the first implementation, the on-demand SSB is measured first, which can be understood as: first measure the on-demand SSB, and then measure other measurement targets other than the on-demand SSB.

[0151] It should be understood that in this implementation, after receiving the first and second instruction information, the terminal device ignores other measurement targets and directly measures the on-demand SSB.

[0152] In the second implementation, the terminal device can perform measurements in the order of different measurement targets.

[0153] When the measurement order of on-demand SSB is greater than or equal to the measurement order of other measurement targets, on-demand SSB shall be measured first.

[0154] For example, if the measurement order of the on-demand SSB is the same as the measurement order of other measurement targets, the terminal device will measure the on-demand SSB first, and then measure the other measurement targets.

[0155] For example, if other measurement targets are measured in a sequence greater than that of the on-demand SSB, then the terminal device will measure the on-demand SSB first, and then measure the other measurement targets.

[0156] For example, the terminal device skips the measurement target indicated by the current measurement sequence and measures the on-demand SSB first.

[0157] Optionally, prior to step S640, for example in step S610, the terminal device receives the measurement sequence of the on-demand SSB.

[0158] In the third implementation, the second indication information received by the terminal device instructs the on-demand SSB transmission of multiple serving cells.

[0159] In this case, in addition to prioritizing the measurement of the on-demand SSB according to the first or second implementation method described above, the terminal device can measure the on-demand SSB corresponding to each of the multiple serving cells according to the order of the multiple serving cells, that is, measure the on-demand SSB corresponding to each of the multiple serving cells in sequence according to the order of the multiple serving cells.

[0160] The following describes several methods for terminal devices to perform measurements in the order of multiple serving cells.

[0161] In the first implementation, the terminal device sequentially measures the on-demand SSB of the multiple serving cells according to their identifier order.

[0162] For example, in the MAC CE of the active serving cell, the identifier of SCell 1 is first and the identifier of SCell 2 is second. Then the UE can perform measurements based on the default SCell identifier order, that is, first measure the on-demand SSB of SCell 1, and then measure the on-demand SSB of SCell 2.

[0163] In the second implementation, the network device indicates the measurement order of the plurality of serving cells to the terminal device, and the terminal device measures the on-demand SSB of the plurality of serving cells in sequence according to the measurement order.

[0164] For example, if the network device instructs multiple serving cells to be measured in the following order: SCell 2, SCell 1, SCell 3, then the terminal device will first measure the on-demand SSB of SCell 2, then measure the on-demand SSB of SCell 1, and then measure the on-demand SSB of SCell 3.

[0165] The network device may instruct the terminal device on the measurement sequence in the following ways:

[0166] 1) Add a field indicating the measurement order after the identifier of each SCell in MAC CE, for example: SCell 1, measurement order 2; SCell 2, measurement order 1; SCell 3, measurement order 3.

[0167] 2) Add a field indicating the measurement order to the last field in MAC CE, for example: SCell 2, SCell 1, SCell 3.

[0168] Optionally, the network device may also instruct that the on-demand SSB of a portion of the multiple serving cells be measured preferentially, while the on-demand SSB of the remaining serving cells are not measured preferentially.

[0169] For example, the network device instructs that the on-demand SSB of SCell 1 and SCell 2 be measured first, and the on-demand SSB of SCell 3 be measured second. That is, the on-demand SSB of SCell 3 is measured along with other measurement targets in their respective measurement order.

[0170] Furthermore, the network device sends an on-demand SSB, including: the network device sending the on-demand SSB of the multiple serving cells sequentially based on the measurement order indicated to the UE for the multiple serving cells.

[0171] For example, if a network device instructs multiple serving cells to perform measurements in the following order: SCell 2, SCell 1, SCell 3, then the network device will first send the on-demand SSB for SCell 2, then send the on-demand SSB for SCell 1, and then send the on-demand SSB for SCell 3.

[0172] Optionally, before step S640, for example in step S610, the terminal device receives the order corresponding to each of the plurality of serving cells.

[0173] In step S650, the terminal device sends the on-demand SSB measurement results to the network device. Correspondingly, the network device receives the on-demand SSB measurement results.

[0174] S660 (optional step): The network device sends a third instruction message to the terminal device. The third instruction message is used to instruct the network device to stop sending on-demand SSB.

[0175] For example, if a network device believes that the service quality of a cell does not meet the requirements or that the cell has been activated, the network device can stop sending on-demand SSB and send the third instruction information to the terminal device.

[0176] Optionally, the third indication information can be carried by MAC CE. For example, the third indication information can be a 1-bit field, with a value of 0 indicating that the network device should stop sending on-demand SSB, or with a value of 1 indicating that the network device should stop sending on-demand SSB.

[0177] With the above scheme, before sending on-demand SSB, the network device instructs the terminal device to prioritize the measurement of on-demand SSB, enabling the terminal device to quickly complete the measurement of on-demand SSB and saving the energy consumption of the network device in sending on-demand SSB.

[0178] Furthermore, the above scheme can also enable network devices to dynamically instruct terminal devices whether to prioritize on-demand SSB measurements.

[0179] For example, when rapid SCell activation is required, the network device can instruct the terminal device to prioritize measuring the on-demand SSB. The terminal device will then measure the on-demand SSB based on this initial instruction. After the measurement is complete, the terminal device sends the result to the network device (PCell). Using this scheme, the network device can quickly activate the SCell. Simultaneously, the network device (SCell) can stop sending on-demand SSB data, saving energy.

[0180] For example, when rapid SCell activation is not required, such as in mobility scenarios where measuring cell quality at high-priority frequencies is more important, network devices may not instruct terminal devices to prioritize on-demand SSB measurements. Terminal devices can prioritize other measurements based on existing rules, such as higher priority for measuring different frequency points or a higher measurement order for a certain target.

[0181] Therefore, network devices can instruct terminal devices to prioritize on-demand SSB measurements when SCell needs to be quickly activated by dynamic signaling (first indication information), rather than modifying the measurement order configuration in the measurement target using RRC, which is more flexible and faster.

[0182] The measurement method provided in this application can also be applied to ORAN systems or in network device CU-DU separation architectures. For example, method 600 in an ORAN system can be executed according to the steps in method 700 below. It should be understood that only the execution steps of method 600 in an ORAN system are described here, and the concepts and terms in method 700 can be referred to method 600, and will not be repeated here.

[0183] Figure 7 This is a schematic diagram of a measurement method 700 provided in an embodiment of this application. Figure 7 The method 700 shown may include the following steps.

[0184] S710: CU sends serving cell configuration information to DU, and DU sends serving cell configuration information to terminal equipment.

[0185] The description of the service cell configuration information can be found in step S610.

[0186] S720 (optional step): The CU instructs the DU to start sending on-demand SSB (i.e., send the second instruction information), and instructs to prioritize the measurement of on-demand SSB (i.e., send the first instruction information).

[0187] Alternatively, the DU sends an instruction to the CU to send an on-demand SSB message, and upon receiving this message, the CU sends a first instruction message to the DU.

[0188] The description of the first instruction information and the second instruction information can be referred to in steps S620 and S630.

[0189] S730, DU sends first instruction information and second instruction information to the terminal device.

[0190] Optionally, if the second indication information indicates on-demand SSB transmission for multiple serving cells, the DU can also indicate the measurement order of the multiple serving cells, as can be found in step S640 where the network device indicates the measurement order of the multiple serving cells.

[0191] Optionally, if step S720 is not executed, after the DU sends the first instruction information and the second instruction information to the terminal device, it can send information to the CU to indicate that the DU has sent the first instruction information and the second instruction information to the terminal device.

[0192] S740, DU sends on-demand SSB to the terminal device.

[0193] Optionally, if the second indication information instructs multiple serving cells to send on-demand SSBs, then the DU can send the multiple serving cells' on-demand SSBs sequentially according to the measurement order of the multiple serving cells.

[0194] S750, the terminal device prioritizes measuring the on-demand SSB based on the first instruction information.

[0195] This step can be referred to as step S640.

[0196] S760, the terminal device sends the on-demand SSB measurement results to the CU.

[0197] After receiving the measurement results, the S770 CU sends an instruction message to the DU, instructing the DU to stop sending on-demand SSB.

[0198] S780, DU sends an on-demand SSB to the terminal device to send a deactivated MAC CE (i.e., an example of a third indication message), instructing the terminal device to stop sending on-demand SSB.
