Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a communication method and device. Background Art

[0002] Cell measurement is one of the contents of the Radio Resource Management (RRM) function. Its purpose is to monitor the communication quality of the service cell and / or neighboring cells of the user equipment (UE) in real time, so that when the signal quality of the service cell deteriorates to a certain extent, the service cell of the UE can be changed through switching or cell selection / reselection to ensure the continuity of the UE service. In the communication system, the UE can perform two types of cell measurements, including co-frequency measurement and inter-frequency measurement. Co-frequency measurement means that the cell where the UE is currently located and the target cell to be measured are on the same carrier frequency (center frequency or BWP (Bandwidth Part) frequency). Inter-frequency measurement means that the cell where the UE is currently located and the target cell to be measured are not on the same carrier frequency (center frequency or BWP frequency).

[0003] When the UE needs to perform inter-frequency measurement (including inter-standard measurement) in each measurement cycle (such as discontinuous reception (DRX) cycle), one approach is to install two types of RF receivers in the UE to measure the frequency of the local cell and the frequency of the target cell respectively. However, this approach will increase costs and cause interference between different frequencies. In response to the above problems, the 3rd Generation Partnership Project (3GPP) proposed a measurement method based on measurement gap, that is, a portion of time is reserved (i.e., measurement gap time), and the UE will not send or receive any data during the measurement gap time, and the receiver will be adjusted to the frequency of the target cell to achieve inter-frequency measurement for the UE. Afterwards, at the end of the measurement gap time, the UE adjusts the receiver to the frequency of the current local cell. Therefore, the inter-frequency measurement of terminal equipment with two types of RF receivers needs further study. Summary of the invention

[0004] The present application provides a communication method and device for realizing dynamic indication of inter-frequency measurement, thereby improving user experience.

[0005] In a first aspect, the present application provides a communication method, which can be performed by a first communication device. Optionally, the first communication device can be a terminal device or a module of the terminal device (such as a processor, a chip, a chip system or a circuit, etc.). The method can also be implemented by a logical node, a logical module or software that can implement all or part of the functions of the terminal device. Exemplarily, the following takes the execution of the communication method by a terminal device as an example. The method may include the following steps: the terminal device receives a first indication message, wherein the first indication message can be used to indicate whether the heterodyne measurement of the terminal device is allowed to be performed by a low-power wake-up receiver, or the first indication message can also be used to indicate whether the heterodyne measurement of the terminal device is allowed to be performed by a main receiver.

[0006] In this method, the indication content of the first indication information can be dynamically adjusted. Therefore, the first indication information can be used to dynamically indicate which receiver is to perform the heterofrequency measurement of the terminal device. After that, after receiving the first indication information, the terminal device can effectively perform the heterofrequency measurement. In this way, dynamic indication of heterofrequency measurement (or flexible indication) can be achieved, and the rationality and accuracy of the terminal device's execution of heterofrequency measurement can be guaranteed, thereby improving the user experience.

[0007] In one possible design, the first indication information may include a first parameter, wherein the first parameter may be used to indicate that heterodyne measurement of the terminal device is allowed to be performed by a main receiver or by a low power consumption wake-up receiver.

[0008] In the above design, the indication of the first parameter can enable the terminal device to promptly and effectively know whether the heterofrequency measurement of the terminal device is performed by the main receiver or the low-power wake-up receiver, thereby achieving flexible indication of heterofrequency measurement.

[0009] In one possible design, when the first indication information includes a first parameter, the first indication information is used to indicate that the inter-frequency measurement of the terminal device is allowed to be performed by the main receiver or is used to indicate that the inter-frequency measurement of the terminal device is not allowed to be performed by the low power wake-up receiver; when the first indication information does not include the first parameter, the first indication information is used to indicate that the inter-frequency measurement of the terminal device is allowed to be performed by the low power wake-up receiver or is used to indicate that the inter-frequency measurement of the terminal device is not allowed to be performed by the main receiver.

[0010] In the above design, whether the first parameter appears in the first indication information is used to indicate whether the heterofrequency measurement of the terminal device is performed by the main receiver or the low-power wake-up receiver, so that flexible indication of heterofrequency measurement can also be achieved.

[0011] In one possible design, when the first indication information indicates that the inter-frequency measurement of the terminal device is not allowed to be performed by the low-power wake-up receiver, or the first indication information indicates that the inter-frequency measurement of the terminal device is allowed to be performed by the main receiver, the first indication information can also be used to indicate the execution rules of the main receiver to perform the inter-frequency measurement, wherein the execution rule can be any one of the following: the main receiver does not relax the inter-frequency measurement period when performing the inter-frequency measurement of the terminal device, or the main receiver relaxes the inter-frequency measurement period by m times when performing the inter-frequency measurement of the terminal device; wherein m can be any value in {3,5,7,10,20}.

[0012] In the above design, when the inter-frequency measurement of the terminal device is allowed to be performed by the main receiver or the inter-frequency measurement of the terminal device is not allowed to be performed by the low-power wake-up receiver, considering the power consumption of the main receiver, it is determined according to the actual situation or the actual scenario whether the main receiver needs to relax the inter-frequency measurement cycle when performing the inter-frequency measurement of the terminal device. For example, when the main receiver needs to relax the inter-frequency measurement cycle when performing the inter-frequency measurement of the terminal device, the first indication information can be used to indicate how many times the inter-frequency measurement cycle needs to be relaxed, which can help save the power consumption (such as power consumption) of the terminal device.

[0013] In a possible design, the first indication information may also be used to indicate whether the measurement interval corresponding to the heterofrequency measurement of the terminal device is effective.

[0014] In the above design, an indication information is used to indicate which receiver performs the heterofrequency measurement of the terminal device, and to indicate whether the measurement interval corresponding to the heterofrequency measurement of the terminal device is effective. This can save signaling overhead and resource overhead, and enable the terminal device to obtain these two indications at the same time.

[0015] In one possible design, when the first indication information indicates that the inter-frequency measurement of the terminal device is allowed to be performed by the low-power wake-up receiver, or the first indication information indicates that the inter-frequency measurement of the terminal device is not allowed to be performed by the main receiver, the first indication information can also be used to indicate that the measurement interval corresponding to the inter-frequency measurement of the terminal device is not effective.

[0016] In the above design, the first indication information indicates that the measurement interval corresponding to the heterofrequency measurement of the terminal device is not effective. This can ensure that when the time domain resource position corresponding to the data transmission (or service transmission) overlaps with the time domain resource position corresponding to the measurement interval, the data transmission (or service transmission) for the terminal device will not be interrupted, which helps to ensure that the data transmission (or service transmission) can be completed within the transmission delay requirement, thereby improving the user experience.

[0017] In one possible design, the method also includes: the terminal device can receive second indication information, wherein the second indication information can also be used to indicate whether the measurement interval corresponding to the heterofrequency measurement of the terminal device is effective.

[0018] In the above design, the second indication information is used to indicate whether the measurement interval corresponding to the heterofrequency measurement of the terminal device is effective. This can reduce the load of the first indication information, help save the indication overhead of the first indication information, and avoid the terminal device misunderstanding the true indication of the first indication information due to the large amount of content indicated by the first indication information.

[0019] In one possible design, when the first indication information indicates that the inter-frequency measurement of the terminal device is performed by the low-power wake-up receiver, or the first indication information indicates that the inter-frequency measurement of the terminal device is not allowed to be performed by the main receiver, the second indication information can be used to indicate that the measurement interval corresponding to the inter-frequency measurement of the terminal device is not effective.

[0020] In the above design, the second indication information indicates that the measurement interval corresponding to the heterofrequency measurement of the terminal device is not effective. This can ensure that when the time domain resource position corresponding to the data transmission (or service transmission) overlaps with the time domain resource position corresponding to the measurement interval, the data transmission (or service transmission) for the terminal device will not be interrupted, which helps to ensure that the data transmission (or service transmission) can be completed within the transmission delay requirements, thereby improving the user experience.

[0021] In one possible design, the method also includes: the terminal device may send a fourth indication information, wherein the fourth indication information may include at least one of the following: power consumption requirement, coverage requirement, performance requirement, latency requirement, which receiver is expected to perform the heterofrequency measurement, whether the expected heterofrequency measurement interval is effective, or the expectation to send the first indication information to indicate that the low power consumption wake-up receiver shall perform the heterofrequency measurement.

[0022] In the above design, by sending the fourth indication information, the receiving end (such as a network device) can determine the indication content of the first indication information based on the fourth indication information, so that the indication content of the first indication information can meet the actual needs of the terminal device, which helps to avoid unnecessary errors caused by the indication content of the first indication information not meeting the actual needs of the terminal device.

[0023] In a second aspect, the present application provides a communication method, which can be performed by a second communication device. Optionally, the second communication device can be a network device or a module of a network device (such as a processor, a processing unit, a chip, a chip system or a circuit, etc.). The method can also be implemented by a logical node, a logical module or software that can implement all or part of the functions of the network device. Exemplarily, the following takes the execution of a communication method by a network device as an example. The method may include the following steps: the network device sends a first indication message, wherein the first indication message can be used to indicate whether the heterodyne measurement of the terminal device is allowed to be performed by a low-power wake-up receiver, or the first indication message can also be used to indicate whether the heterodyne measurement of the terminal device is allowed to be performed by a main receiver.

[0025] In one possible design, the first indication information may include a first parameter, wherein the first parameter may be used to indicate that heterodyne measurement of the terminal device is allowed to be performed by a main receiver or by a low power wake-up receiver.

[0026] In one possible design, when the first indication information includes a first parameter, the first indication information is used to indicate that the inter-frequency measurement of the terminal device is allowed to be performed by the main receiver or is used to indicate that the inter-frequency measurement of the terminal device is not allowed to be performed by the low power wake-up receiver. When the first indication information does not include the first parameter, the first indication information is used to indicate that the inter-frequency measurement of the terminal device is performed by the low power wake-up receiver.

[0027] In one possible design, when the first indication information indicates that the inter-frequency measurement of the terminal device is not allowed to be performed by the low-power wake-up receiver, or the first indication information indicates that the inter-frequency measurement of the terminal device is allowed to be performed by the main receiver, the first indication information can also be used to indicate the execution rules of the main receiver to perform the inter-frequency measurement, wherein the execution rule can be any one of the following: the main receiver does not relax the inter-frequency measurement period when performing the inter-frequency measurement of the terminal device, or the main receiver relaxes the inter-frequency measurement period by m times when performing the inter-frequency measurement of the terminal device; wherein m can be any value in {3,5,7,10,20}.

[0032] In one possible design, the method also includes: the network device may receive a fourth indication information from the terminal device, wherein the fourth indication information may include at least one of the following: power consumption requirement, coverage requirement, performance requirement, latency requirement, which receiver is expected to perform the heterofrequency measurement, whether the expected heterofrequency measurement interval is effective, or the expectation to send the first indication information to indicate that the low power consumption wake-up receiver is to perform the heterofrequency measurement.

[0033] In one possible design, the method also includes: the network device can determine the indication content of the first indication information based on the fourth indication information.

[0034] In one possible design, the method also includes: the network device can determine the indication content of the first indication information based on the size relationship between the delay threshold of the first service and the set delay threshold, wherein the first service is a downlink service received by the terminal device.

[0035] In the above design, by comparing the delay threshold of the first service with the set delay threshold, it is possible to accurately determine whether the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver or the main receiver, and whether the measurement interval corresponding to the heterofrequency measurement of the terminal device is effective.

[0036] In one possible design, the method further includes: the network device receives third indication information, wherein the third indication information may include a delay threshold of the first service.

[0056] The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0057] The following is an introduction to possible communication system architectures applicable to the communication method provided in this application. It should be noted that these introductions are for the convenience of understanding by those skilled in the art and do not limit the scope of protection claimed in this application.

[0058] Figure 1 The following is a schematic diagram of a possible communication system architecture applicable to the embodiments of the present application. Figure 1 As shown, the communication system architecture includes at least one terminal device (such as terminal device 101, terminal device 102, etc.), access network (such as (R)AN) device 200, and core network (CN) device 300. Optionally, the communication system architecture may also include the Internet. For example, the terminal device (such as terminal device 101 or terminal device 102, etc.) can be connected to the access network device 200 in a wireless manner, and the access network device 200 can be connected to the core network device 300 in a wireless or wired manner. The core network device 300 and the access network device 200 can be independent and different physical devices, or the functions of the core network device 300 and the logical functions of the access network device 200 can be integrated on the same physical device, or the functions of some core network devices and some wireless access network devices can be integrated on one physical device. Terminal devices and terminal devices, and access network devices and access network devices can be connected to each other in a wired or wireless manner. Exemplarily, the communication system architecture may also include other network devices (such as wireless relay devices or wireless backhaul devices, etc.).

[0059] The following is a brief introduction to the functions of some devices included in the communication system architecture.

[0060] Terminal equipment: It is an entity on the user side that has the function of sending and receiving signals, and can provide users with service functions such as video, voice, and data connectivity. For example, the terminal equipment is the entrance for mobile users to interact with the network, and can provide basic computing and storage capabilities, display service windows to users, and receive user operation inputs. The next generation terminal equipment (NextGen UE) can use the new air interface technology to establish a signal connection and a data connection with the access network device 200, thereby transmitting control signals and service data to the mobile network.

[0061] Optionally, the terminal device may also be referred to as a terminal, user equipment (UE), access terminal equipment, vehicle-mounted terminal, industrial control terminal, UE unit, UE station, mobile station, mobile station (MS), mobile terminal (MT), remote station, remote terminal equipment, mobile equipment, UE terminal equipment, terminal equipment, wireless communication equipment, UE agent or UE device, etc. In an embodiment of the present application, the terminal device (such as terminal device 101 or terminal device 102, etc.) may be fixed or mobile, and the implementation of the present application does not limit this. Exemplarily, the terminal device (such as terminal device 101 or terminal device 102, etc.) may be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted, or may be deployed on the water (such as a ship, etc.), or may be deployed in the air (such as an airplane, a balloon or a satellite, etc.).

[0062] Exemplarily, the terminal device (such as the terminal device 101 or the terminal device 102, etc.) can be a mobile phone, a tablet computer (Pad), a customer-premises equipment (CPE), a subscriber unit (subscriber unit), a cellular phone (cellular phone), a smart phone (smart phone), a wireless data card, a personal digital assistant (PDA) computer, a wireless modem (modem), a handheld device (handset), a laptop computer (laptop computer), a computer with a wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal in industrial control (industrial control), a vehicle-mounted terminal device, a wireless terminal in self-driving, a wireless terminal in remote medical, a wireless terminal in a smart grid (smart grid), a wireless terminal in transportation safety (transportation safety), a wireless terminal in a smart city (smart city), a smart home (smart home), etc. The present invention relates to wireless terminals in homes, wearable terminal devices, vehicles, drones, helicopters, airplanes, factory machines / equipment, machine type communication (MTC) terminals, ships or robots, etc. The embodiments of the present application do not limit the specific technology and specific device form used by the terminal device.

[0063] Access network device 200: sometimes also referred to as RAN entity, RAN node, network device, or access node, etc., constitutes a part of the communication system to help terminal devices (such as terminal device 101 or terminal device 102, etc.) achieve wireless access. For example, access network device 200 can provide network access functions for authorized users in a specific area, and can determine transmission tunnels of different qualities to transmit user data according to the user's level, business requirements, etc. Access network device 200 can manage its own resources, use them reasonably, provide access services to terminal devices on demand, and is responsible for forwarding control signals and user data between terminal devices (such as terminal devices 101 or terminal devices 102, etc.) and core network device 300. Optionally, access network device 200 can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; it can also be deployed on the water; it can also be deployed on aircraft, drones, balloons and satellites in the air. The embodiment of the present application does not limit the application scenario of the access network device.

[0064] Exemplarily, the access network device 200 may include, but is not limited to: a next generation base station (next generation NodeB, gNB) in a fifth generation (5G) communication system, a next generation base station in a sixth generation (6G) communication system, a base station in a future communication system, a transmission reception point (transmission reception point, TRP), an evolved Node B (eNB), a radio network controller (radio network controller, RNC), a Node B (Node B, NB), a base station controller (base station controller, BSC), a base transceiver station (base transceiver station, BTS), a home base station (for example, home evolved Node B, or homeNode B, HNB), a base band unit (base band unit, BBU), or a wireless fidelity (wireless fidelity, Wi-Fi) access point (access point, AP), etc.

[0065] Optionally, in a network structure, the access network device 200 may also include a centralized unit (CU) or a distributed unit (DU). This structure can split the protocol layer of the access network device 200, and the functions of some protocol layers are placed in the CU for centralized control, and the functions of the remaining part or all of the protocol layers are distributed in the DU, and the DU is centrally controlled by the CU. For example, the functions of the packet data convergence protocol (PDCP) layer and above can be set in the CU, and the functions of the protocol layers below the PDCP (such as the RLC layer and the medium access control (MAC) layer, etc.) are set in the DU. It should be noted that this division of the protocol layer is only an example, and it can also be divided in other protocol layers. The radio frequency device can be remote and not placed in the DU, or it can be integrated in the DU, or part of it can be remotely located and part of it can be integrated in the DU. The embodiments of the present application do not impose any restrictions. In addition, in some embodiments, the control plane (CP) and user plane (UP) of the CU can be separated and implemented by different entities, namely, the control plane CU entity (CU-CP entity) and the user plane CU entity (CU-UP entity).

[0066] In different systems, CU (or CU-CP and CU-UP) or DU may also have different names, but those skilled in the art can understand their meanings. For example, in an open radio access network (ORAN) system, CU may also be called an open CU (open-CU, O-CU), DU may also be called an open DU (open-DU, O-DU), CU-CP may also be called an open CU-CP (open-CU-CP, O-CU-CP), and CU-UP may also be called O-CU-UP. For the convenience of description, this application takes CU, CU-CP, CU-UP and DU as examples for description. Any unit in the CU (or CU-CP, CU-UP) and DU in this application may be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0067] In this network architecture, the signaling generated by the CU can be sent to the terminal device through the DU, or the signaling generated by the terminal device can be sent to the CU through the DU. The DU can directly encapsulate the signaling through the protocol layer and transparently transmit it to the terminal device or CU without parsing it. In this network architecture, the CU is divided into a network device on the radio access network (RAN) side. In addition, the CU can also be divided as a network device on the core network (CN) side, and this application does not limit this.

[0068] Exemplarily, the access network device 200 is a base station, and the terminal device is a terminal device 101. Multiple access network devices 200 can be base stations of the same type or different types. The base station can communicate with the terminal device 101, or it can communicate with the terminal device 101 through a relay station. Optionally, the terminal device 101 can communicate with multiple access network devices 200 equipped with different communication technologies. For example, the terminal device 101 can communicate with a base station that supports an LTE network, or it can communicate with a base station that supports a 5G network, and it can also support dual connections with a base station equipped with an LTE network and a base station equipped with a 5G network.

[0069] It is understandable that the access network device and the terminal device can communicate through a licensed spectrum, or through an unlicensed spectrum, or through both a licensed spectrum and an unlicensed spectrum. The access network device and the terminal device can communicate through a spectrum below the sixth generation mobile communication system (6th generation mobile networks or 6th generation wireless systems, 6G), or through a spectrum above 6G, or can use a spectrum below 6G and a spectrum above 6G at the same time. The embodiment of the present application does not limit the spectrum resources used between the access network device and the terminal device.

[0070] Core network device 300: responsible for maintaining the subscription data of the mobile network, managing the network elements of the mobile network, and providing functions such as session management, mobility management, policy management, and security authentication for the terminal devices. When the terminal device is attached, it provides network access authentication for the terminal device; when the terminal device has a service request, it allocates network resources for the terminal device; when the terminal device moves, it updates network resources for the terminal device; when the terminal device is idle, it provides a fast recovery mechanism for the terminal device; when the terminal device is detached, it releases network resources for the terminal device; when the terminal device has service data, it provides data routing functions for the terminal device, such as forwarding uplink data to the data network; or receiving downlink data of the terminal device from the Internet, forwarding it to the access network device 200, and then sending it to the terminal device by the access network device 200. Optionally, in terms of functional logic, the network elements of the core network can be divided into two parts: user plane network elements and control plane network elements. Among them, the user plane network elements are responsible for the transmission of service data. For example, the user plane network elements can include but are not limited to user plane function (UPF) network elements. The control plane network element is responsible for the management of the mobile network. For example, the control plane may include but is not limited to the access and mobility management function (AMF) network element, the session management function (SMF) network element, the unified data management (UDM) network element, the policy control function (PCF) network element, the application function (AF) network element, the authentication server function (AUSF) network element, and the network slice selection function (NSSF) network element. Of course, the core network may also include other network elements (such as the network exposure function (NEF) network element, the network storage function (NRF) network element, the unified data repository (UDR) network element, the network slice-specific authentication and authorization function (NSSAAF) network element, etc.), which are not listed here one by one.

[0071] For example, the core network control plane adopts a service-oriented architecture, and the interaction between control plane network elements adopts the service call method to replace the point-to-point communication method in the traditional architecture. In the service-oriented architecture, the control plane network elements will open services to other control plane network elements for other control plane network elements to call; in point-to-point communication, the communication interface between control plane network elements will store a set of specific messages, which can only be used by the control plane network elements at both ends of the interface when communicating.

[0072] It should be understood that the communication method provided in the embodiment of the present application can be applicable to downlink signal (or downlink data or downlink information) transmission, or can also be applicable to uplink signal (or uplink data or uplink information) transmission, or can also be applicable to device-to-device (D2D) signal transmission. For downlink signal transmission, the sending device is an access network device, and the corresponding receiving device is a terminal device. For uplink signal transmission, the sending device is a terminal device, and the corresponding receiving device is an access network device. For D2D signal transmission, the sending device is a terminal device, and the corresponding receiving device is also a terminal device. The embodiment of the present application does not limit the transmission direction of the signal (or data or information).

[0073] Optional, Figure 1 The communication system shown can be various communication systems, for example, it can be an Internet of Things (IoT) system, a narrowband Internet of Things (NB-IoT) system, a long term evolution (LTE) system, or a fifth generation mobile communication system (5th generation mobile networks or 5th generation wireless systems, 5G), or a hybrid architecture of LTE and 5G, or a 5G new radio (NR) system, and a new communication system that will appear in the development of 6G or future communications, etc., and the embodiments of the present application do not limit this. The 5G communication system described in the present application may include at least one of a non-standalone (NSA) 5G communication system and a standalone (SA) 5G communication system. The communication system may also be a machine to machine (M2M) network or other network. In addition, Figure 1The communication system architecture shown is intended to more clearly illustrate the technical solution of the embodiment of the present application, and does not constitute a limitation on the technical solution provided in the embodiment of the present application. Ordinary technicians in this field can know that with the evolution of the communication system architecture and the emergence of new business scenarios, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

[0074] For example, Figure 1 The communication system shown is an example of a 5G mobile communication system. The design and development targets of the 5G mobile communication system are mobile phones and vertical usage scenarios. In addition to latency, reliability, and feasibility, energy efficiency is also critical to UE. Currently, UE may need to be charged weekly or daily, depending on individual usage time. In general, 5G devices consume tens of milliwatts in radio resource control (RRC) idle / RRC inactive state and hundreds of milliwatts in RRC connected state. Designing for extended battery life is a prerequisite for improving energy efficiency and better user experience.

[0075] Energy efficiency is even more critical for UEs without continuous energy sources, such as those using small rechargeable batteries and single-coin batteries. In vertical use cases, such as sensors and actuators are widely deployed for monitoring, measurement, charging, etc., usually, their batteries are non-rechargeable and are expected to be used for at least a few years. In some IoT scenarios, such as wearable devices including smart watches, rings, electronic health-related devices, and medical monitoring devices, it is challenging to maintain a battery life of up to 1-2 weeks while maintaining performance at typical battery capacities.

[0076] Among them, the power consumption depends on the length of the configured wake-up cycle. For example, in the RRC idle state, the power consumption depends on the configured paging cycle (such as a discontinuous reception (DRX) cycle or an extended discontinuous reception (eDRX) cycle). The longer the configured paging cycle, the longer the user equipment will enter the sleep state to achieve energy saving. In order to meet the battery life requirements, the UE can be periodically woken up once in each eDRX cycle, where the value of the eDRX cycle will be large. However, while using the eDRX cycle to achieve higher energy efficiency, it will result in higher latency, which is not suitable for services that require both long battery life and low latency. For example, in the fire detection and fire extinguishing use case, the fire shutters should be closed within 1 to 2 seconds after the sensor detects the fire, and the fire sprinklers should be opened by the actuator, but the longer eDRX cycle cannot meet the latency requirements, so the eDRX cycle is obviously not suitable for scenarios with high latency requirements. Therefore, at present, the UE is awakened periodically in each DRX cycle. When the UE is awake, but there is no signaling or data service transmission during the awakening period, the UE is in an invalid awakening state, and the power consumption during this period dominates the overall power consumption of the UE. If the UE is awakened only when it needs to transmit signaling or data services, such as receiving its own paging message, the power consumption of the UE can be greatly reduced. Therefore, achieving energy saving of the UE is also an important means to further improve the user experience.

[0077] Higher energy saving gains can be achieved by using a wake-up signal to trigger a main receiver (MR) and a separate receiver (such as a low power wake up receiver (LP-WUR)) with ultra-low power monitoring wake-up signal capability. In a mobile communication network, when the signal quality of the service cell where the UE is located deteriorates to a certain extent, the service cell of the UE is changed by switching or cell selection / reselection to ensure the continuity of the UE service. Before switching or cell selection / reselection to change the service cell of the UE, the UE usually needs to stop receiving the signal and data of its service cell during a specified time period, and receive the signal of the cell to be measured for measurement. This time period is called a measurement gap, measurement gap or measurement gap. That is, within the measurement gap, the UE will adjust the UE's receiver to the frequency point where the cell to be measured is located for measurement, and then switch to the frequency point of the current cell at the end of the measurement gap. For example, the measurement interval can be a non-periodic period of time, or it can be multiple periodic time periods.

[0078] However, for UE with high data transmission delay requirements or services with high transmission delay requirements, when the time domain resource position corresponding to the measurement gap overlaps with the time domain resource position corresponding to data transmission (or service transmission), since the time period of the measurement gap is used for heterofrequency measurement, the receiver cannot perform data transmission (or service transmission), resulting in interruption of data transmission (or service transmission), thereby affecting the user experience.

[0079] In view of this, an embodiment of the present application provides a communication method for achieving data transmission (or service transmission) within the transmission delay requirement, and can realize dynamic indication of which receiver performs the heterodyne measurement, thereby improving the user experience.

[0080] The following is based on Figure 1 The communication system architecture shown in the figure is combined with the accompanying drawings to introduce in detail the specific implementation of the communication method in the embodiment of the present application.

[0081] Figure 2 The following is a flow chart showing a communication method provided by an embodiment of the present application. Figure 1 The communication system architecture shown in the figure. The method flow can be implemented by data interaction between multiple communication devices (such as a first communication device and a second communication device). Optionally, the first communication device can be a terminal device or a module of a terminal device (such as a processor, chip, chip system or circuit, etc.), or it can also be a logical node, logic module or software that can implement all or part of the terminal functions; the second communication device can be a network device or a module of a network device (such as a processor, chip, chip system or circuit, etc.), or it can also be a logical node, logic module or software that can implement all or part of the network device functions. Exemplarily, the terminal device can be as follows Figure 1 The terminal device 101 or the terminal device 102 shown in the figure, the network device can be such as Figure 1 The access network device 200 is shown. In order to facilitate the introduction of the technical solution provided by the embodiment of the present application, the following takes the first communication device as a terminal device and the second communication device as a network device as an example to introduce the process of implementing the communication method by data interaction between the first communication device and the second communication device. Figure 2 As shown, the method includes:

[0082] Step 201: The network device sends first indication information. Correspondingly, the terminal device receives the first indication information from the network device.

[0083] Step 202: The terminal device performs heterofrequency measurement according to the first indication information.

[0084] Optionally, in an embodiment of the present application, if the terminal device is replaced by a functional module such as a chip system, the functional module may not be aware of which device the received information comes from; if the network device is replaced by a functional module such as a chip system, the functional module may not be aware of which device the sent information is sent to.

[0085] Optionally, if the network device is a distributed architecture, for example, the network device includes a CU and / or a DU, or includes one or more of a CU-CP, a CU-UP, or a DU, when the network device includes a DU, the network device sends the first indication information, specifically, the DU included in the network device sends the first indication information. Optionally, the network device including the DU may also include a CU; or, the network device including the DU may also include a CU-CP and / or a CU-UP.

[0086] Exemplarily, the first indication information may be downlink control information (DCI), or may be indication information carried by the DCI, or may be understood as an indication parameter in some scenarios.

[0087] The following describes the indication content of the first indication information through the following possible implementation methods.

[0088] Implementation method 1: The first indication information can be used to indicate whether the inter-frequency measurement of the terminal device is allowed to be performed by the low-power wake-up receiver, or the first indication information can also be used to indicate whether the inter-frequency measurement of the terminal device is allowed to be performed by the main receiver.

[0089] The following describes the indication of the first indication information in the above-mentioned implementation method 1 through the following possible examples.

[0090] Example 1: Whether the inter-frequency measurement of the terminal device is allowed to be performed by the low-power wake-up receiver or whether the inter-frequency measurement of the terminal device is allowed to be performed by the main receiver can be indicated by the corresponding changes in the first indication information (such as content changes or format changes or length changes or field changes, etc.).

[0091] For example, taking the corresponding change of the first indication information as a length change as an example, when the length of the first indication information is the first length, the first indication information can be used to indicate that the inter-frequency measurement of the terminal device is allowed to be performed by the low-power wake-up receiver, or the first indication information can also be used to indicate that the inter-frequency measurement of the terminal device is not allowed to be performed by the main receiver.

[0092] When the length of the first indication information is the second length, the first indication information can be used to indicate that the inter-frequency measurement of the terminal device is not allowed to be performed by the low-power wake-up receiver, or the first indication information can also be used to indicate that the inter-frequency measurement of the terminal device is allowed to be performed by the main receiver.

[0093] Example 2: Whether the inter-frequency measurement of the terminal device is allowed to be performed by the low-power wake-up receiver or whether the inter-frequency measurement of the terminal device is allowed to be performed by the main receiver can be indicated by a parameter (such as parameter s) carried by the first indication information. Exemplarily, parameter s can use (or occupy) 1 bit to implement the corresponding indication content.

[0094] For example, when the parameter value (or bit value) of the parameter s carried by the first indication information is s1 (such as 1), the first indication information can be used to indicate that the inter-frequency measurement of the terminal device is allowed to be performed by the low-power wake-up receiver, or the first indication information can also be used to indicate that the inter-frequency measurement of the terminal device is not allowed to be performed by the main receiver. When the parameter value of the parameter s carried by the first indication information is s2 (such as 0), the first indication information can be used to indicate that the inter-frequency measurement of the terminal device is not allowed to be performed by the low-power wake-up receiver, or the first indication information can also be used to indicate that the inter-frequency measurement of the terminal device is allowed to be performed by the main receiver.

[0095] Example 3: Whether the inter-frequency measurement of the terminal device is allowed to be performed by the low-power wake-up receiver or whether the inter-frequency measurement of the terminal device is allowed to be performed by the main receiver can be indicated by the parameter type (such as parameter 1 or parameter 2) carried by the first indication information.

[0096] For example, when the parameter type carried by the first indication information is parameter 1, the first indication information can be used to indicate that the inter-frequency measurement of the terminal device is allowed to be performed by the low-power wake-up receiver, or the first indication information can also be used to indicate that the inter-frequency measurement of the terminal device is not allowed to be performed by the main receiver. When the parameter type carried by the first indication information is parameter 2, the first indication information can be used to indicate that the inter-frequency measurement of the terminal device is not allowed to be performed by the low-power wake-up receiver, or the first indication information can also be used to indicate that the inter-frequency measurement of the terminal device is allowed to be performed by the main receiver.

[0097] Example 4: Whether the inter-frequency measurement of the terminal device is allowed to be performed by the low power wake-up receiver or whether the inter-frequency measurement of the terminal device is allowed to be performed by the main receiver can be indicated by whether a certain parameter appears in the first indication information.

[0098] For example, take a certain parameter as the first parameter. When the first indication information carries (or includes or contains) the first parameter, the first indication information can be used to indicate that the inter-frequency measurement of the terminal device is allowed to be performed by the main receiver, or the first indication information can also be used to indicate that the inter-frequency measurement of the terminal device is not allowed to be performed by the low-power wake-up receiver. It should be understood that when the first parameter appears, the first parameter can be understood as the first indication information. When the first indication information does not carry (or does not include or contain) the first parameter, the first indication information can be used to indicate that the inter-frequency measurement of the terminal device is not allowed to be performed by the main receiver, or the first indication information can also be used to indicate that the inter-frequency measurement of the terminal device is allowed to be performed by the low-power wake-up receiver.

[0099] Example 5: Which receiver is allowed to perform the inter-frequency measurement of the terminal device (for example, whether the inter-frequency measurement of the terminal device is allowed to be performed by the low-power wake-up receiver or the main receiver) can be indicated by a parameter (for example, a first parameter). The first parameter is included in the first indication information. Exemplarily, the first parameter can implement the corresponding indication content by using 1 bit.

[0100] For example, when the parameter value of the first parameter (or can be understood as a bit value) is a first value (such as 1), the first parameter is used to indicate that the inter-frequency measurement of the terminal device is allowed to be performed by the low-power wake-up receiver or is used to indicate that the inter-frequency measurement of the terminal device is not allowed to be performed by the main receiver; when the parameter value of the first parameter is a second value (such as 0), the first parameter is used to indicate that the inter-frequency measurement of the terminal device is performed by the main receiver or is used to indicate that the inter-frequency measurement of the terminal device is not allowed to be performed by the low-power wake-up receiver.

[0101] Example 6: Which receiver is allowed to perform the inter-frequency measurement of the terminal device (for example, whether the inter-frequency measurement of the terminal device is allowed to be performed by the low-power wake-up receiver or the main receiver) can be indicated by whether a certain parameter (such as the first parameter) appears.

[0102] For example, take a certain parameter as the first parameter. When the first indication information carries the first parameter, the first indication information is used to indicate that the inter-frequency measurement of the terminal device is allowed to be performed by the main receiver or is used to indicate that the inter-frequency measurement of the terminal device is not allowed to be performed by the low-power wake-up receiver. When the first indication information does not carry the first parameter, the first indication information is used to indicate that the inter-frequency measurement of the terminal device is allowed to be performed by the low-power wake-up receiver or is used to indicate that the inter-frequency measurement of the terminal device is not allowed to be performed by the main receiver.

[0103] Based on the contents provided in the above examples 1 to 6, when the first indication information indicates that the inter-frequency measurement of the terminal device is performed by the low-power wake-up receiver, the network device may broadcast (or send) a signal adapted to the low-power wake-up receiver so that the terminal device receives the signal through the low-power wake-up receiver to perform inter-frequency measurement. For example, the signal adapted to the low-power wake-up receiver may be broadcast periodically.

[0104] When the first indication information indicates that the heterofrequency measurement of the terminal device is allowed to be performed by the main receiver or the first indication information indicates that the heterofrequency measurement of the terminal device is not allowed to be performed by the low-power wake-up receiver, the network device can broadcast a synchronization signal block (Synchronization Signal Block, SSB) so that the terminal device receives the SSB through the main receiver to perform heterofrequency measurement.

[0105] It can be understood that when the first indication information indicates that the inter-frequency measurement of the terminal device is allowed to be performed by the main receiver or the first indication information indicates that the inter-frequency measurement of the terminal device is not allowed to be performed by the low-power wake-up receiver, due to the large power consumption of the main receiver, it is also necessary to consider whether the inter-frequency measurement cycle can be relaxed. If the inter-frequency measurement cycle is not relaxed, the terminal device needs to perform an inter-frequency measurement in each inter-frequency measurement cycle. If the inter-frequency measurement cycle is relaxed, such as relaxing 3 times, the terminal device only needs to perform an inter-frequency measurement once in every 3 cycles. In other words, for every 3 cycles, the terminal device only needs to select one cycle in the 3 cycles for inter-frequency measurement, and the other cycles of the 3 cycles do not need to perform inter-frequency measurement, then the terminal device can enter a sleep state (or hibernation state) at the corresponding measurement interval position in the other cycles of the 3 cycles, so that the terminal device can achieve the effect of energy saving. Based on this, the first indication information can also be used to indicate the execution rules of the inter-frequency measurement of the terminal device performed by the main receiver. For example, the execution rule may be any of the following: the main receiver does not relax the inter-frequency measurement period when performing the inter-frequency measurement of the terminal device, or the main receiver relaxes the inter-frequency measurement period by m times when performing the inter-frequency measurement of the terminal device, where m is any value in {3, 5, 7, 10, 20}.

[0106] Exemplarily, the following describes the indication of the execution rule of the inter-frequency measurement of the terminal device executed by the main receiver through the following possible examples.

[0107] Example 1: The execution rule of the inter-frequency measurement of the terminal device executed by the main receiver can be indicated by whether a certain parameter (such as the second parameter) appears.

[0108] Exemplarily, taking a certain parameter as the second parameter as an example, the second parameter can implement the corresponding indication content by using 1 bit, or can also implement the corresponding indication content by using 2 bits, and the embodiments of the present application are not limited to this. It should be understood that in some cases, the second parameter can be the first parameter. In addition, it can be understood that in some cases, the second parameter can also be understood as the first indication information.

[0109] In one example, take the second parameter as an example to implement the corresponding indication content by using 1 bit. When the second parameter appears, there are two different parameter values ​​(or can be understood as bit values, such as 0, 1) used to indicate different indication contents. For example, when the parameter value of the second parameter is 0, the parameter value 0 can indicate that the heterofrequency measurement of the terminal device is performed by the main receiver, and indicates that the main receiver does not relax the heterofrequency measurement period when performing the heterofrequency measurement of the terminal device. When the parameter value of the second parameter is 1, the parameter value 1 can indicate that the heterofrequency measurement of the terminal device is performed by the main receiver, and can also indicate that when the main receiver performs the heterofrequency measurement, the heterofrequency measurement period is relaxed by m times, such as 3 times.

[0110] In another example, the second parameter is used to implement the corresponding indication content by using 2bit as an example. In the case where the second parameter appears, there are four different parameter values ​​(such as 00, 01, 10, 11) for indicating different indication contents. Among them, one parameter value is used to indicate that the inter-frequency measurement of the terminal device is performed by the low-power wake-up receiver, and the remaining three different parameter values ​​are used to indicate that the inter-frequency measurement of the terminal device is performed by the main receiver, and corresponds to different relaxation multiples. For example, when the parameter value of the second parameter is 00, the parameter value 00 can indicate that the inter-frequency measurement of the terminal device is performed by the low-power wake-up receiver. When the parameter value of the second parameter is 01, the parameter value 01 can indicate that the inter-frequency measurement of the terminal device is performed by the main receiver, and indicates that the main receiver does not relax the inter-frequency measurement cycle when performing the inter-frequency measurement of the terminal device. When the parameter value of the second parameter is 10, the parameter value 10 can indicate that the inter-frequency measurement of the terminal device is performed by the main receiver, and indicates that the main receiver relaxes the inter-frequency measurement cycle x times when performing the inter-frequency measurement of the terminal device, such as 3 times. When the parameter value of the second parameter is 11, the parameter value 11 may indicate that the main receiver performs inter-frequency measurement of the terminal device, and indicates that the main receiver relaxes the inter-frequency measurement period by y times, for example, by 5 times, when performing the inter-frequency measurement of the terminal device. Wherein, x, y is a value in {3, 5, 7, 10, 20}.

[0111] Example 2: The execution rule of the inter-frequency measurement of the terminal device executed by the main receiver can be indicated by a parameter (such as the third parameter) carried by the first indication information.

[0112] Exemplarily, taking a certain parameter as the third parameter as an example, the third parameter can use 1 bit to implement the corresponding indication content, and the third parameter is included in the first indication information. It should be understood that in some cases, the third parameter can also be the first parameter.

[0113] For example, take a certain parameter as the third parameter. When the first indication information carries a first value for the parameter value of the third parameter, it indicates that the heterofrequency measurement of the terminal device is performed by the main receiver, and the main receiver relaxes the heterofrequency measurement period by x times when performing the heterofrequency measurement, such as relaxing it by 3 times. When the first indication information carries a second value for the parameter value of the third parameter, it indicates that the heterofrequency measurement of the terminal device is performed by the main receiver, and the main receiver relaxes the heterofrequency measurement period by y times when performing the heterofrequency measurement, such as relaxing it by 3 times. When the first indication information carries a third value for the parameter value of the third parameter, it indicates that the heterofrequency measurement of the terminal device is performed by the main receiver, and the main receiver relaxes the heterofrequency measurement period by z times when performing the heterofrequency measurement, such as relaxing it by 7 times. Wherein, x, y, z is a value in {3,5,7,10,20}.

[0114] Example 3: The execution rule of the inter-frequency measurement of the terminal device executed by the main receiver can be indicated by a parameter (such as the fourth parameter) carried by the first indication information.

[0115] For example, taking a certain parameter as the fourth parameter, the fourth parameter can implement the corresponding indication content by using 2 bits, or can also implement the corresponding indication content by using 3 bits, and the embodiment of the present application does not limit this. It should be understood that in some cases, the fourth parameter can also be the first parameter.

[0116] For example, take the fourth parameter as an example to implement the corresponding indication content by using 2bit. Different indication contents are represented by different parameter values ​​corresponding to the fourth parameter (such as 00, 01, 10, 11). Among them, one parameter value is used to indicate that the inter-frequency measurement of the terminal device is performed by the low-power wake-up receiver, and the remaining three different parameter values ​​are used to indicate that the inter-frequency measurement of the terminal device is performed by the main receiver, and corresponds to different relaxation multiples. For example, when the parameter value of the fourth parameter is 00, the parameter value 00 can indicate that the inter-frequency measurement of the terminal device is performed by the low-power wake-up receiver. When the parameter value of the fourth parameter is 01, the parameter value 01 can indicate that the inter-frequency measurement of the terminal device is performed by the main receiver, and indicates that the main receiver does not relax the inter-frequency measurement cycle when performing the inter-frequency measurement of the terminal device. When the parameter value of the fourth parameter is 10, the parameter value 10 can indicate that the inter-frequency measurement of the terminal device is performed by the main receiver, and indicates that the main receiver relaxes the inter-frequency measurement cycle by x times when performing the inter-frequency measurement of the terminal device, such as 3 times. When the parameter value of the fourth parameter is 11, the parameter value 11 may indicate that the main receiver performs the inter-frequency measurement of the terminal device, and indicates that the main receiver relaxes the inter-frequency measurement period by y times, for example, 5 times, when performing the inter-frequency measurement of the terminal device. Wherein, x, y is a value in {3, 5, 7, 10, 20}.

[0117] In an embodiment of the present application, when the first indication information is used to indicate whether the inter-frequency measurement of the terminal device is allowed to be performed by the low-power wake-up receiver, or is used to indicate whether the inter-frequency measurement of the terminal device is allowed to be performed by the main receiver, the first indication information can also be used to indicate whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective.

[0118] Optionally, when the first indication information is used to indicate whether the inter-frequency measurement of the terminal device is allowed to be performed by the low-power wake-up receiver, or is used to indicate whether the inter-frequency measurement of the terminal device is allowed to be performed by the main receiver, whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective can also be realized through the second indication information. For example, the network device can indicate whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective by sending the second indication information to the terminal device.

[0119] In a possible implementation, when the first indication information indicates that the inter-frequency measurement of the terminal device is performed by the low-power wake-up receiver or indicates that the inter-frequency measurement of the terminal device is not performed by the main receiver, the first indication information can also be used to indicate that the measurement interval corresponding to the inter-frequency measurement of the terminal device is not effective.

[0120] In another possible implementation, when the first indication information indicates that the inter-frequency measurement of the terminal device is not performed by the low-power wake-up receiver or indicates that the inter-frequency measurement of the terminal device is performed by the main receiver, the first indication information may not indicate whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective, or may indicate that the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective, or may indicate that the measurement interval corresponding to the inter-frequency measurement of the terminal device maintains the current state (such as a state that has been configured and effective, a state that has been configured but not effective, or a state that has not been configured).

[0121] In one example, whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective can be indicated by carrying a parameter (such as parameter a) in the first indication information.

[0122] For example, take the parameter a carried by the first indication information as an example. When the parameter value of the parameter a carried by the first indication information is a1 (such as 1), the first indication information can also be used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device is not effective. For example, when the first indication information indicates that the heterofrequency measurement of the terminal device is not performed by the main receiver or indicates that the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver, if the parameter value of the parameter a carried by the first indication information is a1, it means that the measurement interval is not effective, and the main receiver of the terminal device will not perform heterofrequency measurement. At this time, the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver.

[0123] When the parameter value of parameter a carried by the first indication information is a2 (for example, 0), the first indication information can also be used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device is effective, or can also be used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device maintains the current state (for example, a state that has been configured and has been effective, a state that has been configured but not effective, or a state that has not been configured). Optionally, when the first indication information does not carry parameter a, it is assumed (or indicated or indicated) that the first indication information does not indicate whether the measurement interval corresponding to the heterofrequency measurement of the terminal device is effective. It can be understood that the network device does not indicate the effectiveness of the measurement interval corresponding to the heterofrequency measurement of the terminal device. For example, when the first indication information indicates that the heterofrequency measurement of the terminal device is performed by the main receiver or indicates that the heterofrequency measurement of the terminal device is not performed by the low-power wake-up receiver, if the first indication information does not carry parameter a, the terminal device can perform heterofrequency measurement through the main receiver.

[0124] In another example, whether the measurement interval corresponding to the heterofrequency measurement of the terminal device is effective can be indicated by the parameter type (such as parameter a or parameter b) carried in the first indication information.

[0125] For example, take the parameter type carried by the first indication information as parameter a or parameter b. When the parameter type carried by the first indication information is parameter a, the first indication information can also be used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device is not effective. For example, when the first indication information indicates that the heterofrequency measurement of the terminal device is not performed by the main receiver or indicates that the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver, if the parameter type carried by the first indication information is parameter a, it means that the measurement interval is not effective, and the main receiver of the terminal device will not perform heterofrequency measurement. At this time, the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver.

[0126] When the parameter type carried by the first indication information is parameter b, it is assumed that the first indication information does not indicate whether the measurement interval corresponding to the heterofrequency measurement of the terminal device is effective, or the first indication information can also be used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device is effective, or can also be used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device maintains the current state. For example, when the first indication information indicates that the heterofrequency measurement of the terminal device is performed by the main receiver or indicates that the heterofrequency measurement of the terminal device is not performed by the low-power wake-up receiver, if the parameter type of the first indication information is parameter b, the terminal device can perform heterofrequency measurement through the main receiver.

[0127] In yet another example, whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective can be indicated by whether a certain parameter (such as parameter a) appears in the first indication information.

[0128] For example, take parameter a as an example. As an example, when the first indication information carries parameter a, the first indication information can also be used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device is not effective. It should be understood that when parameter a appears, parameter a can be understood as the first indication information. For example, when the first indication information indicates that the heterofrequency measurement of the terminal device is not performed by the main receiver or indicates that the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver, if the first indication information carries parameter a, it means that the measurement interval is not effective, and the main receiver of the terminal device will not perform heterofrequency measurement. At this time, the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver.

[0129] When the first indication information does not carry parameter a, the first indication information may also be used to indicate that the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective, or may also be used to indicate that the measurement interval corresponding to the inter-frequency measurement of the terminal device maintains the current state. For example, when the first indication information indicates that the inter-frequency measurement of the terminal device is performed by the main receiver or indicates that the inter-frequency measurement of the terminal device is not performed by the low-power wake-up receiver, if the first indication information carries parameter a, the terminal device may perform the inter-frequency measurement through the main receiver.

[0130] In another possible implementation, when the first indication information indicates that the inter-frequency measurement of the terminal device is performed by the low-power wake-up receiver or indicates that the inter-frequency measurement of the terminal device is not performed by the main receiver, the network device may also send to the terminal device second indication information for indicating that the measurement interval corresponding to the inter-frequency measurement of the terminal device is not effective. For example, the second indication information may be DCI, or may be indication information carried by DCI, or may be understood as an indication parameter in some scenarios.

[0131] In another possible implementation, when the first indication information indicates that the inter-frequency measurement of the terminal device is not performed by the low-power wake-up receiver or indicates that the inter-frequency measurement of the terminal device is performed by the main receiver, the second indication information sent by the network device to the terminal device may not indicate whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective, or may also indicate that the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective, or may also indicate that the measurement interval corresponding to the inter-frequency measurement of the terminal device maintains the current state (such as a state that has been configured and effective, a state that has been configured but not effective, or a state that has not been configured).

[0132] In one example, whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective can be indicated by carrying a parameter (such as parameter c) in the second indication information. Exemplarily, the parameter c can implement the corresponding indication content by using 1 bit.

[0133] For example, take the parameter carried by the second indication information as parameter c. When the parameter value of the parameter c carried by the second indication information is c1 (such as 1), the second indication information can be used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device is not effective. For example, when the first indication information indicates that the heterofrequency measurement of the terminal device is not performed by the main receiver or indicates that the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver, if the parameter value of the parameter c carried by the first indication information is c1, it means that the measurement interval is not effective, and the main receiver of the terminal device will not perform heterofrequency measurement. At this time, the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver.

[0134] When the parameter value of parameter c carried by the second indication information is c2 (for example, 0), the second indication information can be used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device is effective, or it can also be used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device maintains the current state. Optionally, when the second indication information does not carry parameter c, it is assumed that the second indication information does not indicate whether the measurement interval corresponding to the heterofrequency measurement of the terminal device is effective. It can be understood that the network device does not indicate the effectiveness of the measurement interval corresponding to the heterofrequency measurement of the terminal device. For example, when the first indication information indicates that the heterofrequency measurement of the terminal device is performed by the main receiver or indicates that the heterofrequency measurement of the terminal device is not performed by the low-power wake-up receiver, if the second indication information does not carry parameter c or the parameter value of the carried parameter c is c2, the terminal device can perform heterofrequency measurement through the main receiver.

[0135] In another example, whether the measurement interval corresponding to the heterofrequency measurement of the terminal device is effective can be indicated by the parameter type (such as parameter c or parameter d) carried in the second indication information.

[0136] For example, take the parameter type carried by the second indication information as parameter c or parameter d. When the parameter type carried by the second indication information is parameter c, the second indication information can be used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device is not effective. For example, when the first indication information indicates that the heterofrequency measurement of the terminal device is not performed by the main receiver or indicates that the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver, if the parameter type carried by the second indication information is parameter c, it means that the measurement interval is not effective, and the main receiver of the terminal device will not perform heterofrequency measurement. At this time, the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver.

[0137] When the parameter type carried by the second indication information is parameter d, it is assumed that the second indication information does not indicate whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective, or the second indication information can also be used to indicate that the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective, or the second indication information can also be used to indicate that the measurement interval corresponding to the inter-frequency measurement of the terminal device maintains the current state. For example, when the first indication information indicates that the inter-frequency measurement of the terminal device is performed by the main receiver or indicates that the inter-frequency measurement of the terminal device is not performed by the low-power wake-up receiver, if the parameter type of the second indication information is parameter d, the terminal device can perform the inter-frequency measurement through the main receiver.

[0138] In yet another example, whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective can be indicated by whether a certain parameter (such as parameter c) appears in the second indication information.

[0139] For example, take a certain parameter as parameter c. As an example, when the second indication information carries parameter c, the second indication information can be used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device is not effective. It should be understood that when parameter c appears, parameter c can be understood as the second indication information. For example, when the first indication information indicates that the heterofrequency measurement of the terminal device is not performed by the main receiver or indicates that the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver, if the second indication information carries parameter c, it means that the measurement interval is not effective, and the main receiver of the terminal device will not perform heterofrequency measurement. At this time, the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver.

[0140] When the second indication information does not carry parameter c, the second indication information can be used to indicate that the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective, or can also be used to indicate that the measurement interval corresponding to the inter-frequency measurement of the terminal device maintains the current state. For example, when the first indication information indicates that the inter-frequency measurement of the terminal device is performed by the main receiver or indicates that the inter-frequency measurement of the terminal device is not performed by the low-power wake-up receiver, if the first indication information does not carry parameter c, the terminal device can perform the inter-frequency measurement through the main receiver.

[0141] For example, the following is combined with Figure 3a and Figure 3b , describes whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective.

[0142] Figure 3a A schematic diagram of a data transmission (or service transmission) and a time domain resource of a measurement interval that do not overlap is provided in an embodiment of the present application. Figure 3a As shown, when there is no time domain resource overlap between data transmission (or service transmission) and the measurement interval (it can be understood that the time domain resource position corresponding to the data transmission (or service transmission) and the time domain resource position corresponding to the measurement interval do not overlap), whether the measurement interval for heterofrequency measurement is configured does not affect the data transmission (or service transmission), so it will not cause a greater data transmission delay. In this case, the measurement interval maintains the existing effective state. For example, if the measurement interval has been configured and has taken effect, the effective state of the measurement interval is not changed; if the measurement interval is not configured, the measurement interval continues to be unconfigured; if the measurement interval has been configured but not taken effect, the configured but ineffective state continues to be maintained.

[0143] For example, when the first indication information indicates that the inter-frequency measurement of the terminal device is not allowed to be performed by the low-power wake-up receiver or indicates that the inter-frequency measurement of the terminal device is allowed to be performed by the main receiver, whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective has no effect on data transmission (or service transmission), so the first indication information may not need to indicate whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective, or the second indication information can also be used to indicate that the measurement interval corresponding to the inter-frequency measurement of the terminal device maintains the current state.

[0144] In one example, after receiving a low power wake up signal (LP-WUS), the low power wake up receiver parses the LP-WUS to obtain an identifier of the terminal device (such as UE-ID). When the identifier of the terminal device is the identifier of the terminal device where the low power wake up receiver is located, the low power wake up receiver can send an indication message to the main receiver, and the indication message is used to wake up the main receiver. After the main receiver is awakened, data transmission (or service transmission) can be performed. Afterwards, during the process of the main receiver performing data transmission (or service transmission), if heterofrequency measurement is required for the terminal device, because the terminal device receives the first indication message from the network device indicating that the heterofrequency measurement of the terminal device is performed by the main receiver, the terminal device can perform heterofrequency measurement through the main receiver.

[0145] In another example, the low-power wake-up receiver can periodically perform co-frequency measurements of the terminal device. For example, within a cycle, after performing co-frequency measurements on the terminal device, the low-power wake-up receiver obtains the co-frequency measurement result (such as the signal quality of the service cell where the terminal device is located), and can compare the co-frequency measurement result with a preset threshold. In the case where the co-frequency measurement result is less than the preset threshold, if the first indication information indicates that the hetero-frequency measurement of the terminal device is performed by the main receiver, the low-power wake-up receiver can send an indication message to the main receiver, and the indication message is used to wake up the main receiver. After waking up, the main receiver can perform hetero-frequency measurements.

[0146] Figure 3b A schematic diagram of a data transmission (or service transmission) and a time domain resource overlap of a measurement interval provided in an embodiment of the present application. Figure 3bAs shown, when there is a time domain resource overlap between data transmission (or service transmission) and the measurement interval (it can be understood that the time domain resource position corresponding to the data transmission (or service transmission) overlaps with the time domain resource position corresponding to the measurement interval), whether the measurement interval for heterofrequency measurement is configured has different effects on data transmission (or service transmission). For example, if the measurement interval has been configured and has taken effect, then since the measurement interval is used by the main receiver to perform heterofrequency measurement, the data transmission (or service transmission) performed by the main receiver will be interrupted, thereby increasing the transmission delay of the data transmission (or service transmission), affecting the network capacity. Based on this, when the measurement interval has been configured and has taken effect or the measurement interval has been configured and has not taken effect, for data (or services) with higher transmission delay requirements, the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver, and the indicated measurement interval is not effective.

[0147] For example, when the first indication information indicates that the inter-frequency measurement of the terminal device is not performed by the main receiver or indicates that the inter-frequency measurement of the terminal device is performed by the low-power wake-up receiver, the measurement interval corresponding to the inter-frequency measurement of the terminal device will take effect because it will affect the data transmission (or service transmission). Therefore, the first indication information can also be used to indicate that the measurement interval corresponding to the inter-frequency measurement of the terminal device is not effective, that is, to disable the configuration of the measurement interval.

[0148] In one example, after receiving the low-power wake-up signal, the low-power wake-up receiver parses the LP-WUS to obtain the identifier of the terminal device (such as UE-ID). When the identifier of the terminal device is the identifier of the terminal device where the low-power wake-up receiver is located, the low-power wake-up receiver can send an indication message to the main receiver, and the indication message is used to wake up the main receiver. After waking up, the main receiver can perform data transmission (or service transmission). Afterwards, during the process of data transmission (or service transmission) by the main receiver, if it is necessary to perform heterofrequency measurement on the terminal device, because the terminal device receives the first indication information from the network device indicating that the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver, the terminal device can perform heterofrequency measurement through the low-power wake-up receiver after invalidating the configuration of the measurement interval.

[0149] In another example, the low-power wake-up receiver can periodically perform co-frequency measurement of the terminal device. For example, within a cycle, after the low-power wake-up receiver performs co-frequency measurement on the terminal device, it obtains the co-frequency measurement result (such as the signal quality of the service cell where the terminal device is located), and can compare the co-frequency measurement result with a preset threshold. In the case where the co-frequency measurement result is less than the preset threshold, if the first indication information indicates that the inter-frequency measurement of the terminal device is performed by the low-power wake-up receiver, the terminal device can perform the inter-frequency measurement through the low-power wake-up receiver.

[0150] Implementation method 2: The first indication information can be used to indicate whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective. It should be understood that at this time, the first indication information does not need to indicate whether the inter-frequency measurement of the terminal device is allowed to be performed by the low-power wake-up receiver, nor does it need to indicate whether the inter-frequency measurement of the terminal device is allowed to be performed by the main receiver.

[0151] In a possible implementation, when the first indication information indicates that the measurement interval corresponding to the inter-frequency measurement of the terminal device is not effective, the inter-frequency measurement of the terminal device is performed by the low-power wake-up receiver by default or the inter-frequency measurement of the terminal device is not performed by the main receiver by default.

[0152] In another possible implementation, when the first indication information indicates that the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective, the inter-frequency measurement of the terminal device is performed by the main receiver by default or the inter-frequency measurement of the terminal device is not performed by the low power wake-up receiver by default.

[0153] In another possible implementation, when the first indication information does not indicate whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective (it can be understood that the first indication information does not indicate the status of the measurement interval corresponding to the terminal device), the inter-frequency measurement of the terminal device is performed by the main receiver by default or the inter-frequency measurement of the terminal device is not performed by the low-power wake-up receiver by default.

[0154] The following describes the indication of whether the measurement interval corresponding to the inter-frequency measurement of the terminal device in the above-mentioned second implementation method is effective through the following possible examples.

[0155] Example 1: Whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective can be indicated by carrying a parameter (such as parameter a) in the first indication information.

[0156] For example, the parameter carried by the first indication information is parameter a. When the parameter value of parameter a carried by the first indication information is a1 (for example, 1), the first indication information is used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device is not effective. It should be understood that when the measurement interval is not effective, the main receiver of the terminal device will not perform heterofrequency measurement. At this time, the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver.

[0157] When the parameter value of parameter a carried by the first indication information is a2 (for example, 0), the first indication information is used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device is effective, or it can also be used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device maintains the current state. In this case, it is assumed that the heterofrequency measurement of the terminal device is performed by the main receiver.

[0158] Optionally, when the first indication information does not carry parameter a, it is assumed that the first indication information does not indicate whether the measurement interval corresponding to the heterofrequency measurement of the terminal device is effective. It can be understood that the network device does not indicate the effectiveness of the measurement interval corresponding to the heterofrequency measurement of the terminal device. In this case, it is assumed that the heterofrequency measurement of the terminal device is performed by the main receiver.

[0159] Example 2: Whether the measurement interval corresponding to the heterodyne measurement of the terminal device is effective can be indicated by the parameter type (such as parameter a or parameter b) carried in the first indication information.

[0160] For example, take the parameter type carried by the first indication information as parameter a or parameter b. When the parameter type carried by the first indication information is parameter a, the first indication information is used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device is not effective. It should be understood that when the measurement interval is not effective, the main receiver of the terminal device will not perform heterofrequency measurement. At this time, the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver.

[0161] When the parameter type carried by the first indication information is parameter b, it is assumed that the first indication information does not indicate whether the measurement interval corresponding to the heterofrequency measurement of the terminal device is effective, or the first indication information can also be used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device is effective, or it can also be used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device maintains the current state. In this case, it is assumed that the heterofrequency measurement of the terminal device is performed by the main receiver.

[0162] Example 3: Whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective can be indicated by whether a certain parameter (such as parameter a) appears in the first indication information.

[0163] For example, take parameter a as an example. As an example, when the first indication information carries parameter a, the first indication information is used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device is not effective. It should be understood that when parameter a appears, parameter a can be understood as the first indication information. It can be understood that when the measurement interval is not effective, the main receiver of the terminal device will not perform heterofrequency measurement. At this time, the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver.

[0164] When the first indication information does not carry parameter a, the first indication information is used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device is effective, or it can also be used to indicate that the measurement interval corresponding to the heterofrequency measurement of the terminal device maintains the current state. In this case, it is assumed that the heterofrequency measurement of the terminal device is performed by the main receiver.

[0165] Based on the above content, the implementation process of the network device determining the indication content of the first indication information is introduced through the following several possible implementation methods.

[0166] Method 1: The network device determines the indication content of the first indication information according to the relationship between the delay threshold of the first service and the set delay threshold.

[0167] For example, the delay threshold may be predefined, such as predefined by a protocol, or may be configured by a network device, or may be pre-negotiated and configured between a terminal device and a network device, or may be indicated by an indication message (such as the fifth indication message) sent by the network device to the terminal device. The embodiments of the present application do not limit this.

[0168] In an embodiment of the present application, before the network device transmits the first service (or the first data) to the terminal device, it may first receive the third indication information. The third indication information may include the delay threshold of the first service (or the first data), the third indication information comes from the core network, and the first service (or the first data) is the downlink service (or downlink data) received by the terminal device. Afterwards, the network device may compare the delay threshold of the first service with the set delay threshold. When the delay threshold of the first service is less than or equal to the set delay threshold, the network device may determine that the indication content of the first indication information is: the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver and / or the measurement interval corresponding to the heterofrequency measurement of the terminal device is not effective. Optionally, when the delay threshold of the first service is less than or equal to the set delay threshold, the network device may also determine that the indication content of the second indication information is: the measurement interval corresponding to the heterofrequency measurement of the terminal device is not effective.

[0169] When the delay threshold of the first service is greater than the set delay threshold, the network device can determine that the indication content of the first indication information includes at least one of the following: the heterodyne measurement of the terminal device is performed by the main receiver, or the measurement interval corresponding to the heterodyne measurement of the terminal device maintains the current state (or the measurement interval corresponding to the heterodyne measurement of the terminal device is effective or does not indicate whether the measurement interval corresponding to the heterodyne measurement of the terminal device is effective). Optionally, when the delay threshold of the first service is greater than the set delay threshold, the network device can also determine that the indication content of the second indication information is: the measurement interval corresponding to the heterodyne measurement of the terminal device maintains the current state (or the measurement interval corresponding to the heterodyne measurement of the terminal device is effective or does not indicate whether the measurement interval corresponding to the heterodyne measurement of the terminal device is effective).

[0170] Optionally, after receiving the third indication information, the network device may also send the third indication information to the terminal device. The terminal device determines, according to the magnitude relationship between the latency threshold of the first service and the set latency threshold, whether the inter-frequency measurement of the terminal device is performed by the primary receiver or by the low-power wake-up receiver, or may also determine whether the measurement interval corresponding to the inter-frequency measurement of the terminal device takes effect. After obtaining the third indication information, the terminal device may compare the latency threshold of the first service with the set latency threshold. When the latency threshold of the first service is less than or equal to the set latency threshold, the terminal device may determine at least one of the following: the inter-frequency measurement of the terminal device is performed by the low-power wake-up receiver, or the measurement interval corresponding to the inter-frequency measurement of the terminal device does not take effect. When the latency threshold of the first service is greater than the set latency threshold, the terminal device may determine at least one of the following: the inter-frequency measurement of the terminal device is performed by the primary receiver, or the measurement interval corresponding to the inter-frequency measurement of the terminal device remains in the current state (or the measurement interval corresponding to the inter-frequency measurement of the terminal device takes effect or no indication is given as to whether the measurement interval corresponding to the inter-frequency measurement of the terminal device takes effect).

[0171] It should be understood that after the terminal device determines whether the inter-frequency measurement of the terminal device is performed by the primary receiver or by the low-power wake-up receiver, or determines whether the measurement interval corresponding to the inter-frequency measurement of the terminal device takes effect, the terminal device may notify the network device of the corresponding determined content (such as determining that the inter-frequency measurement of the terminal device is performed by the primary receiver).

[0172] Method 2: The network device determines the indication content of the first indication information according to the fourth indication information.

[0173] For example, the fourth indication information comes from the terminal device, and the fourth indication information includes at least one of the following: power consumption requirement, coverage requirement, performance requirement, latency requirement, which receiver is expected to perform the inter-frequency measurement, whether the expected inter-frequency measurement interval takes effect, or it is expected that the first indication information indicates that the low-power wake-up receiver performs the inter-frequency measurement.

[0174] In one example, taking the power consumption requirement included in the fourth indication information as an example. When the power consumption requirement included in the fourth indication information is a low power consumption requirement, the network device may determine that the indication content of the first indication information is: the inter-frequency measurement of the terminal device is performed by the low-power wake-up receiver and / or the measurement interval corresponding to the inter-frequency measurement of the terminal device does not take effect. Optionally, when the power consumption requirement included in the fourth indication information is a low power consumption requirement, the network device may also determine that the indication content of the second indication information is: the measurement interval corresponding to the inter-frequency measurement of the terminal device does not take effect.

[0175] When the power consumption requirement included in the fourth indication information is a high power consumption requirement, the network device may determine that the indication content of the first indication information is: the inter-frequency measurement of the terminal device is performed by the main receiver, or the measurement interval corresponding to the inter-frequency measurement of the terminal device maintains the current state (or the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective or does not indicate whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective). Optionally, when the power consumption requirement included in the fourth indication information is a high power consumption requirement, the network device may also determine that the indication content of the second indication information is: the measurement interval corresponding to the inter-frequency measurement of the terminal device maintains the current state (or the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective or does not indicate whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective).

[0176] In another example, take the fourth indication information including coverage requirements as an example. When the coverage requirement included in the fourth indication information is a high coverage requirement, the network device can determine the indication content of the first indication information as follows: the inter-frequency measurement of the terminal device is performed by the main receiver, or the measurement interval corresponding to the inter-frequency measurement of the terminal device maintains the current state (or the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective or does not indicate whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective). Optionally, when the coverage requirement included in the fourth indication information is a high coverage requirement, the network device can also determine the indication content of the second indication information as follows: the measurement interval corresponding to the inter-frequency measurement of the terminal device maintains the current state (or the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective or does not indicate whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective).

[0177] When the coverage requirement included in the fourth indication information is a low coverage requirement, the network device may determine that the indication content of the first indication information is: the inter-frequency measurement of the terminal device is performed by the low-power wake-up receiver and / or the measurement interval corresponding to the inter-frequency measurement of the terminal device is not effective. Optionally, when the coverage requirement included in the fourth indication information is a low coverage requirement, the network device may also determine that the indication content of the second indication information is: the measurement interval corresponding to the inter-frequency measurement of the terminal device is not effective.

[0178] In another example, take the fourth indication information including performance requirements as an example. When the performance requirements included in the fourth indication information are low performance requirements, the network device can determine that the indication content of the first indication information is: the inter-frequency measurement of the terminal device is performed by the low-power wake-up receiver and / or the measurement interval corresponding to the inter-frequency measurement of the terminal device is not effective. Optionally, when the performance requirements included in the fourth indication information are low performance requirements, the network device can also determine that the indication content of the second indication information is: the measurement interval corresponding to the inter-frequency measurement of the terminal device is not effective.

[0179] When the performance requirement included in the fourth indication information is a high-performance requirement, the network device may determine that the indication content of the first indication information is: the heterodyne measurement of the terminal device is performed by the main receiver, or the measurement interval corresponding to the heterodyne measurement of the terminal device maintains the current state (or the measurement interval corresponding to the heterodyne measurement of the terminal device is effective or does not indicate whether the measurement interval corresponding to the heterodyne measurement of the terminal device is effective). Optionally, when the performance requirement included in the fourth indication information is a high-performance requirement, the network device may also determine that the indication content of the second indication information is: the measurement interval corresponding to the heterodyne measurement of the terminal device maintains the current state (or the measurement interval corresponding to the heterodyne measurement of the terminal device is effective or does not indicate whether the measurement interval corresponding to the heterodyne measurement of the terminal device is effective).

[0180] In another example, take the fourth indication information including the latency requirement as an example. When the latency requirement included in the fourth indication information is a low latency requirement, the network device can determine that the indication content of the first indication information is: the inter-frequency measurement of the terminal device is performed by the low-power wake-up receiver and / or the measurement interval corresponding to the inter-frequency measurement of the terminal device is not effective. Optionally, when the latency requirement included in the fourth indication information is a low latency requirement, the network device can also determine that the indication content of the second indication information is: the measurement interval corresponding to the inter-frequency measurement of the terminal device is not effective.

[0181] When the delay requirement included in the fourth indication information is a high delay requirement, the network device can determine the indication content of the first indication information as follows: the inter-frequency measurement of the terminal device is performed by the main receiver, or the measurement interval corresponding to the inter-frequency measurement of the terminal device maintains the current state (or the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective or does not indicate whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective). Optionally, when the delay requirement included in the fourth indication information is a high delay requirement, the network device can also determine the indication content of the second indication information as follows: the measurement interval corresponding to the inter-frequency measurement of the terminal device maintains the current state (or the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective or does not indicate whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective).

[0182] In another example, take the example that the fourth indication information includes which receiver is expected to perform the inter-frequency measurement. When the fourth indication information includes that the inter-frequency measurement is expected to be performed by the main receiver, the network device can determine the indication content of the first indication information as follows: the inter-frequency measurement of the terminal device is performed by the main receiver, or the measurement interval corresponding to the inter-frequency measurement of the terminal device maintains the current state (or the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective or does not indicate whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective). Optionally, when the fourth indication information includes that the inter-frequency measurement is expected to be performed by the main receiver, the network device can also determine the indication content of the second indication information as follows: the measurement interval corresponding to the inter-frequency measurement of the terminal device maintains the current state (or the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective or does not indicate whether the measurement interval corresponding to the inter-frequency measurement of the terminal device is effective).

[0183] When the fourth indication information includes that the inter-frequency measurement is expected to be performed by the low-power wake-up receiver, the network device can determine that the indication content of the first indication information is: the inter-frequency measurement of the terminal device is performed by the low-power wake-up receiver and / or the measurement interval corresponding to the inter-frequency measurement of the terminal device is not effective. Optionally, when the fourth indication information includes that the inter-frequency measurement is expected to be performed by the low-power wake-up receiver, the network device can also determine that the indication content of the second indication information is: the measurement interval corresponding to the inter-frequency measurement of the terminal device is not effective.

[0184] In another example, take the fourth indication information including whether the expected heterofrequency measurement interval is effective. When the fourth indication information includes that the expected heterofrequency measurement interval is not effective, the network device can determine that the indication content of the first indication information is: the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver and / or the measurement interval corresponding to the heterofrequency measurement of the terminal device is not effective. Optionally, when the fourth indication information includes that the expected heterofrequency measurement is performed by the low-power wake-up receiver, the network device can also determine that the indication content of the second indication information is: the measurement interval corresponding to the heterofrequency measurement of the terminal device is not effective.

[0185] When the fourth indication information includes that the measurement interval corresponding to the heterofrequency measurement of the terminal device remains in the current state (or the heterofrequency measurement interval is expected to take effect), the network device can determine that the indication content of the first indication information is: the heterofrequency measurement of the terminal device is performed by the main receiver, or the measurement interval corresponding to the heterofrequency measurement of the terminal device remains in the current state (or the measurement interval corresponding to the heterofrequency measurement of the terminal device takes effect or there is no indication of whether the measurement interval corresponding to the heterofrequency measurement of the terminal device takes effect). Optionally, when the fourth indication information includes that the measurement interval corresponding to the heterofrequency measurement of the terminal device remains in the current state (or the heterofrequency measurement interval is expected to take effect), the network device can also determine that the indication content of the second indication information is: the measurement interval corresponding to the heterofrequency measurement of the terminal device remains in the current state (or the measurement interval corresponding to the heterofrequency measurement of the terminal device takes effect or there is no indication of whether the measurement interval corresponding to the heterofrequency measurement of the terminal device takes effect).

[0186] In another example, take the example that the fourth indication information includes the expectation to send the first indication information to indicate that the low-power wake-up receiver performs heterofrequency measurement. When the fourth indication information includes the expectation to send the first indication information to indicate that the low-power wake-up receiver performs heterofrequency measurement, the network device can determine that the indication content of the first indication information is: the heterofrequency measurement of the terminal device is performed by the low-power wake-up receiver and / or the measurement interval corresponding to the heterofrequency measurement of the terminal device is not effective. Optionally, when the fourth indication information includes the expectation to send the first indication information to indicate that the low-power wake-up receiver performs heterofrequency measurement, the network device can also determine that the indication content of the second indication information is: the measurement interval corresponding to the heterofrequency measurement of the terminal device is not effective.

[0187] It is understandable that any multiple of the multiple examples given in the above-mentioned method 2 can be used in combination.

[0188] It can be seen from the above steps 201 to 202 that the indication content of the first indication information can be dynamically adjusted. Therefore, the first indication information can be used to dynamically indicate which receiver is used to perform the heterofrequency measurement of the terminal device. After that, after receiving the first indication information, the terminal device can effectively perform the heterofrequency measurement. In this way, the dynamic indication of the heterofrequency measurement can be realized, and the rationality and accuracy of the heterofrequency measurement performed by the terminal device can be guaranteed, thereby improving the user experience. For example, in the case of services with high transmission delay requirements or services with low transmission delay requirements, the first indication information can be used to indicate that the heterofrequency measurement of the terminal device is performed by a low-power wake-up receiver, and the measurement interval corresponding to the heterofrequency measurement of the terminal device can be indicated to be invalid. In this way, a smaller delay in service transmission can be guaranteed, and service transmission can be completed within the transmission delay requirement, thereby improving the user experience and increasing network capacity.

[0189] Based on the above Figure 2The technical solution of the communication method shown in the figure, and several application scenarios of the communication method provided in the embodiment of the present application are introduced as examples below.

[0190] Scenario 1: Business switching scenario.

[0191] Figure 4 A schematic diagram of a service switching scenario provided in an embodiment of the present application. Figure 4 As shown, in the service switching scenario, two service switchings (such as the switching of the first service and the second service) are taken as an example. For example, the first service is a service with a lower transmission delay requirement, the second service is a service with a higher transmission delay requirement, and the second service is a periodic service (such as an extended reality (XR) service) as an example. For the first service, since the transmission delay requirement of the first service is relatively low, the configuration of the measurement interval does not affect service transmission. For the second service, taking the second service as an XR service as an example, the period of the XR service is related to the frame rate. For example, when the frame rate is 60fps, the period of the XR video frame is 16.67ms. When the frame rate is 30fps, the period of the XR video frame is 33.33ms. The non-integer period is likely to collide with the time domain resources of the measurement interval configured with an integer period, which may cause interruption of service transmission and affect the user experience. Based on this, the communication scheme provided in the embodiment of the present application can effectively avoid service transmission interruption, so that the user experience is effectively improved.

[0192] against Figure 4 The service switching scenario shown in the figure is described below through the following possible implementations to introduce the sending of the first indication information. The first indication information is used to indicate that the inter-frequency measurement of the terminal device is performed by the low-power wake-up receiver and / or the measurement interval corresponding to the inter-frequency measurement of the terminal device is not effective.

[0193] Method 1: During the process of transmitting a service (such as transmitting the first service, the second service, etc.) from the network device to the terminal device, the first indication information is carried in the last data packet of the first service. For example, the sending position of the first indication information is Figure 4 Position T1 is shown.

[0194] Optionally, the network device may carry an indication information in any data packet before the data packet containing the first indication information (such as the data packet containing position T1), and the indication information is used to indicate in which data packet the first indication information is specifically contained. This allows the terminal device to promptly and effectively know in which data packet the first indication information is specifically contained without having to detect the first indication information for each received packet. It also allows the terminal device to promptly and effectively perform heterofrequency measurements while ensuring normal service transmission.

[0195] Method 2: When the network device transmits a service (such as the first service, the second service, etc.) to the terminal device, the first indication information is carried in the first data packet of the second service. For example, the sending position of the first indication information is Figure 4 Position T3 is shown.

[0196] Optionally, the network device may carry an indication information in any data packet before the data packet where the first indication information is located (such as the data packet where position T3 is located), and the indication information is used to indicate in which data packet the first indication information is specifically located. This allows the terminal device to promptly and effectively know in which data packet the first indication information is specifically located, without having to detect the first indication information for each received packet. It also allows the terminal device to promptly and effectively perform heterofrequency measurements while ensuring normal service transmission.

[0197] Method 3: In the process of transmitting services (such as the first service, the second service, etc.) from the network device to the terminal device, the first indication information is carried in a radio resource control (RRC) message, DCI or media access control layer control element (MAC-CE). The sending time (or sending position) of the RRC message, DCI or MAC-CE is within the switching time period between the first service and the second service. For example, the sending position of the RRC message, DCI or MAC-CE is Figure 4 Position T2 is shown.

[0198] Optionally, in a possible implementation manner, the first indication information in the above-mentioned method three is sent periodically.

[0199] In another possible implementation, the sending method of the first indication information in the above-mentioned method three complies with a rule. For example, the rule is related to the arrival pattern of the service. For example, taking the XR service as an example, when the frame rate is 60fps, the period of the XR video frame is 16.67ms. Because the DRX cycle length is an integer, in order to better adapt to the XR service, the DRX cycle length is configured to 17ms, 17ms, and 16ms within each 50ms. The sending method (or sending pattern) of the first indication information is associated with the configuration of the DRX cycle length. For example, the first indication information is also sent within each 50ms, first at an interval of 17ms, then at an interval of 17ms, and then at an interval of 16ms.

[0200] It should be understood that the sending time (or sending position) of the first indication information depends on whether the network device has resources for sending the first indication information and the arrival time of the second service. It must be ensured that when the second service arrives, which receiver performs the inter-frequency measurement of the terminal device has been determined.

[0201] Scenario 2: The cell load is heavy.

[0202] In scenarios where the cell load is large (or the network is overloaded), resources are relatively scarce. If the heterodyne measurement of the terminal device is performed by the main receiver, the main receiver of the terminal device can receive the existing SSB. However, if the heterodyne measurement of the terminal device is performed by a low-power wake-up receiver, the main receiver of the terminal device needs to receive a newly designed signal adapted to the low-power wake-up receiver. The sending time (or sending position) of this signal is periodic. In this case, the network device has to send both the SSB and the newly designed signal adapted to the low-power wake-up receiver, which is not conducive to the resource efficiency of the network device. Therefore, in scenarios where the cell load is large, the network device can indicate that the heterodyne measurement of the terminal device is performed by the main receiver through the first indication information. At this time, the network device does not send the signal of the newly designed adapted low-power wake-up receiver either.

[0203] It should be noted that in the description of the present application, "at least one" refers to one or more, and "multiple" refers to two or more. "And / or" describes the association relationship of the associated objects, indicating that there may be three relationships, for example, A and / or B, which can represent: the situation where A exists alone, A and B exist at the same time, and B exists alone, wherein A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are an "or" relationship. "At least one of the following (individuals)" or its similar expression refers to any combination of these items, including any combination of single items (individuals) or plural items (individuals).
