Detailed Description

The technical solution in the present application will be described below with reference to the accompanying drawings. It should be apparent that the described embodiments are only some embodiments of the present invention, and not all embodiments.

First, some terms in the embodiments of the present application are explained so as to be easily understood by those skilled in the art.

(1) The terminal equipment: may be a wireless terminal device capable of receiving network device scheduling and indication information, which may be a device providing voice and/or data connectivity to a user, or a handheld device having wireless connection capability, or other processing device connected to a wireless modem. A terminal device, which may be a mobile terminal device such as a mobile telephone (or called a "cellular" phone), a computer, and a data card, for example, a portable, pocket, hand-held, computer-included, or vehicle-mounted mobile device, may communicate with one or more core networks or the internet via a Radio Access Network (RAN). Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, session Initiation Protocol (SIP) phones, wireless Local Loop (WLL) stations, personal Digital Assistants (PDAs), tablet computers (pads), and computers with wireless transceiving functions. A wireless terminal device may also be referred to as a system, a subscriber unit (subscriber unit), a subscriber station (subscriber station), a mobile station (mobile station), a Mobile Station (MS), a remote station (remote station), an Access Point (AP), a remote terminal device (remote terminal), an access terminal device (access terminal), a user terminal device (user terminal), a user agent (user agent), a Subscriber Station (SS), a user terminal device (CPE), a terminal (terminal), a User Equipment (UE), a Mobile Terminal (MT), etc. The terminal device may also be a wearable device and a next generation communication system, for example, a terminal device in a 5G communication system or a terminal device in a Public Land Mobile Network (PLMN) for future evolution, etc.

(2) A network device: may be a device in a wireless network, for example, a network device may be a Radio Access Network (RAN) node (or device) that accesses a terminal device to the wireless network, which may also be referred to as a base station. Currently, some examples of RAN equipment are: a new generation base station (gbodeb), a Transmission Reception Point (TRP), an evolved Node B (eNB), a Radio Network Controller (RNC), a Node B (NB), a Base Station Controller (BSC), a Base Transceiver Station (BTS), a home base station (e.g., a home evolved NodeB or home Node B, HNB), a Base Band Unit (BBU), or a wireless fidelity (Wi-Fi) Access Point (AP), etc. in the 5G communication system. In addition, in one network configuration, the network device may include a Centralized Unit (CU) node, or a Distributed Unit (DU) node, or a RAN device including a CU node and a DU node. Furthermore, the network device may be other means for providing wireless communication functionality for the terminal device, where possible. The embodiments of the present application do not limit the specific technologies and the specific device forms used by the network devices. For convenience of description, in this embodiment of the present application, a device that provides a wireless communication function for a terminal device is referred to as a network device.

(3) The working state of the terminal equipment is as follows: the operating state of the terminal device may include a Radio Resource Control (RRC) IDLE (RRC _ IDLE) state, an RRC Inactive (Inactive) state, and an RRC CONNECTED (RRC _ CONNECTED) state. The RRC idle state may be referred to as an idle state, the RRC inactive state may be referred to as an inactive state, and the RRC connected state may be referred to as a connected state. These three operating states will be described separately below.

In an idle state: after the terminal device accesses the network device through the initial random access process, the network device may store the device parameter of the terminal device, and if the terminal device does not communicate with the network device for a long time, the network device deletes the stored device parameter of the terminal device, and the state of the terminal device is an idle state at this time. In an idle state, the terminal device does not have RRC connection, and may perform cell selection and reselection, monitor a paging channel, and perform Tracking Area Update (TAU). If the terminal device in the idle state needs to communicate with the network device, the random access procedure needs to be initiated again.

Connection state: after the terminal device accesses the network device through the initial random access process, the network device may store the device parameters of the terminal device, during which the terminal device may communicate with the network device, and the state of the terminal device is the connection state. When the terminal device is in the connected state, the terminal device may receive and transmit the dedicated data, and according to the activity of the terminal device, the air interface resource and the power of the terminal device may be saved through Discontinuous Reception (DRX).

In the inactive state: the terminal device in the inactive state and the network device are disconnected from the RRC connection, and do not need to monitor downlink data continuously, so as to achieve the same power saving effect as the idle state, but both the terminal device in the inactive state and the network device store context information of the terminal device, and when the terminal device needs to enter the connected state, the network device may configure the terminal device in the inactive state to enter the connected state based on the stored context information.

(4) The terms "system" and "network" in the embodiments of the present application may be used interchangeably. "at least one" means one or more, "a plurality" means two or more. "and/or" describes the association relationship of the associated objects, meaning that there may be three relationships, e.g., a and/or B, which may mean: a alone, A and B together, and B alone, wherein A and B may be singular or plural. The character "/" generally indicates that the former and latter associated objects are in an "or" relationship. "at least one of the following" or similar expressions refer to any combination of these items, including any combination of the singular or plural items. For example, "at least one of A, B, and C" includes A, B, C, AB, AC, BC, or ABC.

And, unless specifically stated otherwise, the embodiments of the present application refer to the ordinal numbers "first", "second", etc., for distinguishing between a plurality of objects, and do not limit the order, sequence, priority, or importance of the plurality of objects. For example, the first threshold and the second threshold are only used for distinguishing different thresholds, and do not indicate a difference in priority or importance between the two thresholds.

An alternative network architecture to which the embodiments of the present application are applicable is described below with reference to the drawings of the specification.

Fig. 1 is a schematic diagram of a network architecture suitable for use in the embodiment of the present application. As shown in fig. 1, the terminal device 130 may access a wireless network to obtain services of an external network (e.g., the internet) through the wireless network, or may communicate with other devices through the wireless network, such as may communicate with other terminal devices. The wireless network includes a Radio Access Network (RAN) device 110 and a Core Network (CN) device 120, where the RAN device 110 is configured to access a terminal device 130 to the wireless network, and the CN device 120 is configured to manage the terminal device and provide a gateway for communicating with an external network. It should be understood that the number of each device in the communication system shown in fig. 1 is merely an illustration, and the embodiment of the present application is not limited thereto, and in practical applications, more terminal devices 130, more RAN devices 110, and other devices may also be included in the communication system.

The CN device 120 may include a plurality of CN devices 120, when the network architecture shown in fig. 1 is applied to a 5G communication system, the CN device 120 may be an access and mobility management function (AMF) entity, a Session Management Function (SMF) entity, or a User Plane Function (UPF) entity, and when the network architecture shown in fig. 1 is applied to an LTE communication system, the CN device 120 may be a Mobility Management Entity (MME), a serving gateway (S-GW), and the like.

Fig. 2 is a schematic diagram of another network architecture applicable to the embodiment of the present application. As shown in fig. 2, the network architecture includes CN devices, RAN devices, and terminal devices. The RAN device includes a baseband device and a radio frequency device, where the baseband device may be implemented by one node or by multiple nodes, and the radio frequency device may be implemented independently by being pulled away from the baseband device, or integrated in the baseband device, or partially integrated independently, or partially integrated in the baseband device. For example, in an LTE communication system, a RAN equipment (eNB) includes a baseband device and a radio frequency device, where the radio frequency device may be remotely located with respect to the baseband device, e.g., a Remote Radio Unit (RRU) is a remote radio unit located with respect to the BBU.

The communication between the RAN device and the terminal device follows a certain protocol layer structure, for example, the control plane protocol layer structure may include functions of protocol layers such as a Radio Resource Control (RRC) layer, a Packet Data Convergence Protocol (PDCP) layer, a Radio Link Control (RLC) layer, a Medium Access Control (MAC) layer, and a physical layer; the user plane protocol layer structure can comprise functions of protocol layers such as a PDCP layer, an RLC layer, an MAC layer, a physical layer and the like; in a possible implementation, a Service Data Adaptation Protocol (SDAP) layer may be further included above the PDCP layer.

The RAN device may implement the functions of the protocol layers, such as RRC, PDCP, RLC, and MAC, by one node, or may implement the functions of the protocol layers by a plurality of nodes. For example, in an evolved structure, the RAN equipment may include CUs) and DUs, which may be centrally controlled by one CU. As shown in fig. 2, the CU and the DU may be divided according to protocol layers of the radio network, for example, functions of a PDCP layer and above are provided in the CU, and functions of protocol layers below the PDCP layer, for example, a RLC layer and a MAC layer, are provided in the DU.

This division of the protocol layers is only an example, and it is also possible to divide the protocol layers at other protocol layers, for example, at the RLC layer, and set the functions of the RLC layer and the protocol layers above to CU, and the functions of the protocol layers below the RLC layer to DU; alternatively, the functions may be divided into some protocol layers, for example, a partial function of the RLC layer and a function of a protocol layer above the RLC layer may be provided in the CU, and the remaining function of the RLC layer and a function of a protocol layer below the RLC layer may be provided in the DU. In addition, the processing time may be divided in other manners, for example, by time delay, a function that needs to satisfy the time delay requirement for processing is provided in the DU, and a function that does not need to satisfy the time delay requirement is provided in the CU.

In addition, the radio frequency device may be integrated independently, not in the DU, but also in the DU, or partially in the DU, without any limitation herein.

Fig. 3 is a schematic diagram of another network architecture applicable to the embodiment of the present application. With respect to the network architecture shown in fig. 2, the Control Plane (CP) and the User Plane (UP) of the CU may also be separated and implemented by being divided into different entities, namely, a Control Plane (CP) CU entity (i.e., a CU-CP entity) and a User Plane (UP) CU entity (i.e., a CU-UP entity), respectively.

In the above network architecture, the signaling generated by the CU may be sent to the terminal device through the DU, or the signaling generated by the terminal device may be sent to the CU through the DU. The DU may directly encapsulate the signaling through a protocol layer without parsing and then transmit the encapsulated signaling to the terminal device or the CU. In the following embodiments, if transmission of such signaling between the DU and the terminal device is involved, in this case, the transmission or reception of the signaling by the DU includes such a scenario. For example, the signaling of the RRC or PDCP layer is finally processed as the signaling of the PHY layer to be sent to the terminal device, or is converted from the received signaling of the PHY layer. Under this architecture, the signaling of the RRC or PDCP layer can also be considered as being sent by the DU, or sent by the DU and the radio bearer.

The network architecture illustrated in fig. 1, fig. 2, or fig. 3 may be applied to communication systems of various Radio Access Technologies (RATs), which may be a 5G (or new radio, NR) communication system, or a transition system between an LTE communication system and the 5G communication system, which may also be referred to as a 4.5G communication system, and may of course be a future communication system following the 5G communication system. The network architecture and the service scenario described in the embodiment of the present application are for more clearly illustrating the technical solution of the embodiment of the present application, and do not form a limitation on the technical solution provided in the embodiment of the present application, and as a person of ordinary skill in the art knows that along with the evolution of the communication network architecture and the appearance of a new service scenario, the technical solution provided in the embodiment of the present application is also applicable to similar technical problems.

The apparatus in the following embodiments of the present application may be located in a terminal device or a network device according to the functions implemented by the apparatus. When the above structure of CU-DU is adopted, the network device may be a CU node, or a DU node, or a RAN device including the CU node and the DU node.

The following describes related technical features related to embodiments of the present application. It should be noted that these explanations are for the purpose of facilitating the understanding of the examples of the present application, and should not be construed as limiting the scope of the protection claimed in the present application.

1. Minimization of drive tests

Minimization of Drive Tests (MDT) is a work in which an operator performs measurement reporting through a commercial terminal of a subscriber to partially replace the conventional Drive test work, and automatically collects terminal measurement data to detect and optimize problems and faults in a wireless network. The MDT is generally applied to multiple fields such as network planning optimization and the like, the workload of manual drive test can be greatly saved, the operation cost is reduced, and the service accuracy is improved. The MDT mechanism includes the following classes:

1、Immediate MDT

the Immediate MDT is used for configuring radio access network measurement and terminal equipment measurement in a connected state, the configuration of the terminal equipment measurement is based on the existing RRC measurement process, and the terminal equipment can report the measurement report together with the current position information when reporting the measurement report.

2、Logged MDT

The Logged MDT is that the terminal device records measurement results of the serving cell and the neighboring cell and information such as time and coordinates in an idle state, and indicates the network device through an RRC Connection Reconfiguration Complete Message (RRC Connection Reconfiguration Complete Message), an RRC Connection Reestablishment Complete Message (RRC Connection Reconfiguration response Complete Message), or an RRC Connection Setup Complete Message (RRC Connection Setup Complete Message), and the network device obtains the MDT data through an information query procedure of the terminal device. The Logged MDT report may include the following:

serving cell Identity (ID), serving cell measurement: best beam of serving cell, neighbor measurement: beam level measurements.

3、RLF report

RLF is a self-adjusting way that occurs when the system air interface is abnormal or unexpected. After the terminal equipment generates RLF, the terminal equipment reports the RLF Report after the terminal equipment establishes/reestablishes RRC connection. One way for the terminal device to Report the RLF Report is as follows: the terminal equipment reports available indication of the RLF Report, the network equipment sends an RLF Report acquisition request according to the indication of the terminal equipment, and the terminal equipment reports the RLF Report acquisition request to the network equipment according to the RLF Report acquisition request sent by the network equipment. The method for reporting the available indication of the RLF Report by the terminal device is mainly carried in other uplink control signaling, and includes: RRC connection reconfiguration complete message, RRC connection reestablishment complete message, RRC connection establishment complete message, and the like.

The RLF report can be used for timely acquiring link interruption conditions caused by coverage holes, unreasonable parameter setting and the like. The network judges the reason causing the link interruption through the collected information such as the signal strength or quality of the service cell, the signal strength or quality of the adjacent cell, the geographical position and the like when the wireless link fails, thereby optimizing the coverage.

2. Radio Resource Management (RRM) measurements

Mobility management is an important component in wireless mobile communications. It refers to a generic term referring to related content in order to ensure that the communication link between the network device and the terminal device is not interrupted by the movement of the terminal device. The method can be roughly divided into an idle state mobility management part and a connection state mobility management part according to the state of the terminal equipment. In the idle state, mobility management mainly refers to a cell selection/reselection (cell selection/reselection) process. In the connected state, mobility management is mainly referred to as cell handover (handover). Whether cell selection/reselection or handover, is based on the results of radio resource management measurements. Radio resource management measurements are therefore the basis for mobility management.

3. Wave beam

A beam in LTE is a large range, and a beam in LTE corresponds to a range of its communication radiation. In NR, however, a form of coverage is no longer adopted, but a form of beamforming is adopted, and each signal is guided to the optimal path of the terminal receiver, so that the signal strength is improved, and signal interference is avoided, thereby improving the communication quality, and finally, the coverage of the whole cell is realized by continuously changing the direction of the beam. The downlink reference signal for beam management includes:

in an idle state: synchronization Signal and PBCH Block (SSB);

connection state: a Channel State Information Reference Signal (CSI-RS) or SSB;

1. beam measurement

The beam measurement may be one of RRM measurements. In the beam management process, the terminal device or the network device identifies the beam with good signal strength through the measurement of the reference signal. The measurement reference signals related in the uplink and downlink directions in the idle mode and the connected mode are shown in table 1.

TABLE 1

	Idle state	Connected state
Uplink (UL)		SRS
Downstream	SSB	CSI-RS、SSB

2. Beam scanning:

in order to increase the beamforming gain, a high-gain directional antenna is generally used to form a narrow beam width, which tends to cause a problem of insufficient coverage. To avoid this problem, multiple narrow beams may be used in the time domain to scan within the coverage area to meet the coverage requirements within the area.

Beam scanning refers to the transmission and/or reception of a beam in a predetermined manner in a specific period or time period, for example, the beam is transmitted in a predetermined direction and in a fixed period to cover a specific spatial area.

For SSB beams, the network device transmits the beams in different directions at different times through time-sharing scanning. And the terminal equipment selects the SSB with the best signal quality through beam training to complete synchronization and system information demodulation, thereby accessing the corresponding cell. In the prior art, a terminal device operates under a specific beam selected by the terminal device through beam training, and when the specific beam corresponding to the terminal device is scanned, the terminal device can most efficiently receive downlink information sent by a network device and/or send uplink information to the network device. When other beams are scanned, the terminal device cannot efficiently receive downlink information sent by the network device.

For example, during the initial access procedure, the UE needs to synchronize with the system and receive system information. Therefore, a plurality of SSB blocks carrying a Primary Synchronization Signal (PSS), a Secondary Synchronization Signal (SSS), and a PBCH are used to scan and transmit at fixed periods.

The CSI-RS may also employ beam scanning techniques, but it is too costly if all predefined beam directions are to be covered, so the CSI-RS transmits in a specific subset of predefined beam directions depending on the location of the served mobile terminal. For example: the base station sends one or more narrow beams based on the periphery of the range of the initial access SSB beam, CSI-RS corresponding CSI Resource Index (CRI) terminal equipment measures CSI-RS reference signals, reports measurement results of different CRIs, and selects the beam corresponding to the strongest CSI-RS to carry out downlink channel sending.

The CSI-RS reference signals have many functions including: the method is used for measuring downlink channels, beam Management, RRM measurement, radio Link Management (RLM) measurement and time-frequency offset tracking.

4. Measuring relaxation

With the development of mobile communication technology, the power saving requirement of the mobile terminal is higher and higher, and the energy consumption caused by RRM measurement is an important component of the energy consumption of the terminal device. The more the number of the measured SSBs, the number of the cells and the number of the frequencies are, the larger the energy consumption of the terminal equipment is; the smaller the measurement period, i.e. the greater the number of measurements performed per unit of time, the greater the energy consumption of the terminal device.

The power consumption of RRM measurements is also affected by the network measurement configuration. Generally, a terminal device needs to obtain a measurement result with relatively high accuracy through a plurality of measurement samples, and one method for reducing the measurement power consumption is to reduce the measurement samples while ensuring the accuracy. Furthermore, under certain conditions, some RRM measurements by the terminal devices are not necessary but consume a lot of terminal device power, e.g. low mobility terminal devices do not have to measure as frequently as high mobility terminal devices, reducing the frequency of RRM measurements by the terminal devices is also a straightforward and efficient way to reduce RRM measurement power consumption. Therefore, reducing the measurement samples may be referred to as measurement relaxation.

As one of important scenes of New Radio (NR), mass internet of things (mtc) Communication has the characteristics of 5G low power consumption, large connection, low delay and high reliability, so that the mtc mobile terminal is well adapted to services of internet of things, and can mainly solve the problem that the conventional mobile Communication cannot well support internet of things and vertical industry application. The low-power-consumption large connection scene mainly faces application scenes such as smart cities, environment monitoring, intelligent agriculture and forest fire prevention and the like which aim at sensing and data acquisition, and has the characteristics of small data packets, low power consumption, massive connection and the like. The terminal equipment has wide distribution range and large quantity, and not only requires the network to have the support capability of over billions of connections and meet the requirement of 100 ten thousand/km 2 connection number density index, but also ensures the ultra-low power consumption and the ultra-low cost of the terminal. In an mtc scenario, NR reduction Capability terminal devices (redcapabilitys, redcapables) have gained wide attention, and measurement relaxation of RRM measurement is an important research direction to achieve characteristics such as low power consumption.

The measurement referred to in the embodiments of the present application may be understood as RRM measurement.

Based on the above description of the related features, the following provides a general introduction to the technical solutions provided in the embodiments of the present application. It should be noted that, this is only for better understanding the core idea of the technical solution of the embodiment of the present application, and does not represent a limitation to the embodiment of the present application.

The embodiment of the application provides a communication method and a communication device, which are used for completing a report mechanism of minimization of drive test, so that the performance of network planning and optimization is enhanced. Illustratively, the communication method provided by the embodiment of the present application may include two possible schemes, which are referred to as scheme one and scheme two for convenience of description.

In the first solution, the network device sends measurement configuration information to the terminal device, where the measurement configuration information is used for the terminal device to perform radio resource management measurement according to the measurement configuration information, and the terminal device may generate a measurement result after performing the radio resource management measurement. Based on the mobility of the terminal device, the terminal device generates a radio link failure and sends radio link failure information to the network device. Measurement relaxation information indicating whether or not the measurement result of the radio resource management measurement is a result of measurement relaxation and/or a measurement relaxation type of the measurement result of the radio resource management measurement is included in the radio link failure information. By adopting the scheme, the radio link failure report can be perfected, and whether RRM measurement is subjected to measurement relaxation is indicated by adding measurement relaxation information. When the RRM measurement result is subjected to the measurement relaxation, the measurement condition causing the radio link failure may be optimized according to the measurement relaxation information, for example, the terminal device may optimize a parameter related to the measurement relaxation based on the measurement relaxation information. The measurement relaxation information can be added to specifically indicate the type of measurement relaxation, so that the network equipment performs directional optimization on the type of measurement relaxation, and the mobile performance of the terminal equipment is ensured.

In the second scheme, the network device sends minimization drive test configuration information to the terminal device, and the terminal device determines the minimization drive test information according to the minimization drive test configuration information, where the minimization drive test information includes measurement results of m downlink reference signals of the neighboring cell, and may also include indexes of the m downlink reference signals, the m downlink reference signals belong to n downlink reference signals, the n downlink reference signals are measured downlink reference signals of the neighboring cell, and m and n are both natural numbers.

And adopting a second scheme, the terminal equipment executes RRM measurement, reports the measurement result in the MDT report and can report indexes of m downlink reference signals at the same time. And transmitting the indexes of m downlink reference signals in the minimization of drive test information so as to realize the report of the measurement result of the beam level.

The technical solutions provided by the embodiments of the present application are described in detail below with reference to the first embodiment and the second embodiment.

First embodiment

The first embodiment is a possible implementation of the communication method described based on the first aspect. Fig. 4 is a flowchart of a communication method according to a first embodiment of the present application. The method comprises the following steps:

401: the network device sends the measurement configuration information, and the terminal device performs RRM measurement according to the measurement configuration information.

Fig. 5 is a schematic diagram illustrating an alternative RRM measurement timing sequence provided in the first embodiment of the present application, where as shown in fig. 5, the terminal device enters a connected state at time t0, and receives measurement configuration information sent by the network device, and performs RRM measurement according to the measurement configuration information at a first period, where the first period may be indicated by the measurement configuration information sent by the network device.

The terminal device starts to measure relaxation from the time t1, and the measurement state of the terminal device at this time may also be referred to as that the terminal device is in a measurement relaxation state, where the measurement period of the terminal device is the second period. Illustratively, the second period may be three times the first period.

The time at which the dashed arrow in fig. 5 points is the time at which the measurement should originally be performed without measurement relaxation, while in the measurement relaxation state, the terminal device does not perform the measurement. At the time of t2, the quality of the mobile signal of the terminal device is deteriorated, if the measurement is performed at the time of t2, the terminal device may report an A3 event according to the measurement result, and the network device sends a handover command according to the A3 event reported by the terminal device, so as to instruct the terminal device to perform cell handover. And under the measurement relaxation state, not measuring at the time t2 until the time t3, and reporting an A3 event according to the measurement result. And at the moment of t3, the channel quality is deteriorated, and the terminal equipment loses the downlink synchronization in the source cell when the terminal equipment does not successfully receive the switching command. A radio link failure occurs at time t 4.

402: the terminal device sends radio link failure information to the network device, wherein the radio link failure information comprises measurement relaxation information, and the measurement relaxation information is used for indicating whether the measurement result of the radio resource management measurement is the result of the measurement relaxation and/or the type of the measurement relaxation.

When the terminal device has a radio link failure at time t4, the terminal device reports radio link failure information to the network device, where the radio link failure information includes measurement relaxation information, and the measurement relaxation information is used to indicate whether a measurement result of RRM measurement performed by the terminal device is a result subjected to measurement relaxation. It is to be understood that fig. 5 shows only a timing sequence of the RRM measurement procedure, and in the RRM measurement procedure shown in fig. 5, the terminal device performs measurement relaxation after time t1, at this time, the measurement result of the RRM measurement performed by the terminal device is a result of the measurement relaxation, which is indicated by the measurement relaxation information sent by the terminal device to the network device. If the measurement relaxation is not performed when the terminal device performs the RRM measurement, the terminal device may indicate to the network device through the measurement relaxation information that the measurement relaxation is not performed when the terminal device performs the RRM measurement.

When RRM measurement performed by the terminal device is subjected to measurement relaxation, the measurement relaxation information may further include a type of measurement relaxation, and the network device may know, according to the type of measurement relaxation reported by the terminal device, which measurement parameter the terminal device has performed measurement relaxation on. The measurement relaxation information reported by the terminal device may be measurement relaxation information at any time period between the time t0 and the time t 4.

The network device may improve network planning and optimization performance by acquiring measurement relaxation information, and still take the RRM measurement shown in fig. 5 as an example for description. Since the measurement period increases to three times after the time t1 before relaxation, the signal quality of the terminal device deteriorates due to mobility at the time t2, but the network device cannot acquire the information until the time t4 due to relaxation of measurement, thereby causing radio link failure. Therefore, the measurement result with poor signal quality cannot be reported in time due to measurement relaxation, and radio link failure is caused. If there is no measurement relaxation information in the information of the radio link failure report, the network device cannot consider the influence of measurement relaxation when optimizing the measurement, which affects the performance of optimization. The radio link failure information in the first embodiment of the present application includes measurement relaxation information, and the network device can know that the radio link failure is caused by the measurement relaxation, so that optimization can be performed. For example, the measurement period is appropriately shortened, energy is saved by measurement relaxation, and meanwhile, the mobility of the terminal equipment is ensured, and the situation that measurement is not timely due to excessive measurement relaxation, so that handover failure is avoided. The threshold value of cell switching, for example, the threshold value of an A3 event, may also be appropriately reduced, so as to avoid that the measurement event is not reported in time due to over relaxation, which may result in a handover failure, and to ensure mobility of the terminal device while achieving energy saving through measurement relaxation.

As an optional implementation manner, the terminal device may only report one piece of indication information for indicating whether the measurement result of the RRM measurement is a result subjected to measurement relaxation, may also only report one piece of indication information for indicating a type of measurement relaxation performed by the RRM measurement, or report both of them at the same time.

Specifically, the measurement relaxation information can be expressed in the following three ways.

In one mode

Whether the measurement result indicating the RRM measurement is a result of measurement relaxation is indicated in the first field. For example, when the first field is absent, the measurement result indicating the RRM measurement is a result that the measurement relaxation has not been performed, and when the first field is present, the measurement result indicating the RRM measurement is a result that the measurement relaxation has been performed. In case there is a first field, there is a second field for indicating the type of measurement relaxation, and it is also possible to represent different types of measurement relaxation by taking different values through the second field.

The second method comprises the following steps:

the value of the first field is used to indicate whether the measurement result of the RRM measurement is a result of the measurement relaxation. For example, when the first field is 0, the measurement result indicating the RRM measurement is a result that the measurement has not been relaxed, and when the first field is 1, the measurement result indicating the RRM measurement is a result that the measurement has been relaxed. In case the first field takes the value 1, there is a second field for indicating the type of measurement relaxation, and it is also possible to represent different types of measurement relaxation by taking different values through the second field.

The third method comprises the following steps:

whether the measurement result of the RRM measurement is a result of the measurement relaxation and the type of the measurement relaxation are simultaneously indicated by the third field. For example, when the third field takes a value of 000, it indicates that the measurement result of the RRM measurement is a result of not having been relaxed by the measurement. When the value of the third field is 001, the measurement period is extended to indicate the type of measurement relaxation, and other values of the third field indicate other different types of measurement relaxation.

As an alternative embodiment, the radio link failure information may include a measurement result of the RRM measurement, and likewise, the measurement result of the RRM measurement may be a measurement result at any time period between time t0 and time t4 in fig. 5.

In one case, the measurement relaxation information is used to indicate whether the first measurement result is a result of measurement relaxation and/or a type of measurement relaxation, the measurement result included in the radio link failure information is a second measurement result, and the first measurement result and the second measurement result are measurement results of RRM measurements performed by the terminal device at different time periods.

As illustrated in fig. 5, the second measurement result may be a measurement result between time t3 and time t4, and the measurement relaxation information may be measurement relaxation information about the first measurement result between time t0 and time t 3. That is, the measurement result included in the radio link failure information and the measurement result associated with the measurement relaxation information may not necessarily be the same measurement result.

In another case, the measurement relaxation information is used to indicate whether the first measurement result is a result of measurement relaxation and/or a type of measurement relaxation, and the measurement result included in the radio link failure information includes the first measurement result.

For example, the measurement result of the RRM measurement included in the radio link failure information may be a measurement result between the time t0 and the time t4, and the measurement relaxation information is information on measurement relaxation of the first measurement result between the time t0 and the time t 3. At this time, the measurement relaxation information may further indicate which of the measurement results of the RRM measurement included in the radio link failure information the first measurement result is.

In another case, the measurement relaxation information is used to indicate whether the first measurement result is a result of measurement relaxation and/or a type of measurement relaxation, the measurement result included in the radio link failure information is a second measurement result, and the first measurement result includes the second measurement result.

For example, the measurement result of the RRM measurement included in the radio link failure information may be a measurement result between time t2 and time t4, and the measurement relaxation information is information on measurement relaxation of the first measurement result between time t0 and time t 4. For example, the last measurement is reported in the rll report, and the radio link failure information is associated with the measurement since the last report.

The type of optional measurement of relaxation in the first embodiment of the present application will be described below.

The type of measuring relaxation may include one or more of: the measurement period of the relaxed serving cell, the measurement period of the relaxed neighbor cell, the measurement number of downlink reference signals of the relaxed serving cell, the measurement number of downlink reference signals of the relaxed neighbor cell, the measurement number of relaxed cells, or the measurement number of relaxed frequency points.

The measurement period for relaxing the serving cell means that the terminal device will expand the measurement period for measuring the serving cell in the measurement relaxed state. For example, a terminal device not in a measurement relaxed state performs measurement of a reference signal every T1 time, and T1 may be referred to as a measurement period. The terminal device entering the measurement relaxed state will perform the measurement of the reference signal with the first period, for example, the terminal device performs the measurement of the reference signal every T2 time. Wherein, T2 is greater than T1, and T1 and T2 may be configured by the network or agreed by the protocol. When the measurement relaxation type includes a measurement period of a relaxation serving cell, the radio link failure information may further include a first period, and/or the radio link failure information includes a ratio T2/T1 of T2 and T1. T2/T1 represents the magnification of the measurement period, and depending on the value of the magnification and T1, the network device will be able to know the value of the measurement period in the measurement relaxed state.

The measurement period for relaxing the neighbor cell refers to a measurement period in which the terminal device will expand to measure the neighbor cell in a measurement relaxed state. For example, a terminal device not in the measurement relaxation state performs measurement of the reference signal once every T3 time, and T3 may be referred to as a measurement period. The terminal device entering the measurement relaxed state will perform the reference signal measurement at a second period, for example, the terminal device performs the reference signal measurement every T4 time. Wherein, T4 is greater than T3, and T3 and T4 may be configured by the network or may be agreed by the protocol. When the measurement relaxation type includes relaxing the measurement period of the neighbor cell, the radio link failure information may further include a second period, and/or the radio link failure information includes a ratio T4/T3 of T4 to T3. T4/T3 represents the amplification of the measurement period, and depending on the amplification and the value of T3, the network device will be able to learn the value of the measurement period in the measurement relaxed state.

Relaxing the number of measurements of downlink reference signals of the serving cell refers to reducing the number of measurements of downlink reference signals of the serving cell. For example, a terminal device not in a measurement relaxed state performs measurement on M downlink reference signals of a serving cell, and a terminal device entering the measurement relaxed state performs measurement on N downlink reference signals of the serving cell, where N is smaller than M. The N downlink reference signals of the serving cell measured by the terminal device in the measurement relaxed state may be referred to as a first downlink reference signal. It is to be understood that the first downlink reference signals are only for characterizing downlink reference signals measured by the terminal device in the measurement relaxed state, and the N first downlink reference signals measured by the terminal device in the measurement relaxed state may be a subset of M downlink reference signals measured by the terminal device not in the measurement relaxed state. When the type of measurement relaxation includes relaxing the measurement number of the downlink reference signals of the serving cell, the radio link failure information may further include indexes of the N first downlink reference signals. The index information may be represented by a set, for example, the index set includes N elements, each element being an index of a respective downlink reference signal. And/or the radio link failure information may include a value of N representing the number of first downlink reference signals measured in the measurement relaxed state.

Relaxing the number of measurements of downlink reference signals of the neighbor cell means reducing the number of measurements of downlink reference signals of the neighbor cell. For example, a terminal device not in a measurement relaxed state performs measurement on P downlink reference signals of a neighboring cell, and a terminal device entering the measurement relaxed state performs measurement on Q downlink reference signals of the neighboring cell, where Q is smaller than P. Q downlink reference signals of the neighboring cell measured by the terminal device in the measurement relaxed state may be referred to as a second downlink reference signal. It is to be understood that the second downlink reference signals are only for characterizing downlink reference signals measured by the terminal device in the measurement relaxed state, and Q second downlink reference signals measured by the terminal device in the measurement relaxed state may be a subset of P downlink reference signals measured by the terminal device not in the measurement relaxed state. When the measurement relaxation type includes relaxing the measurement number of the downlink reference signals of the neighboring cell, the radio link failure information may further include indexes of Q second downlink reference signals. The index information may be represented by a set, for example, the index set includes Q elements, each element being an index of a respective downlink reference signal. And/or the radio link failure information may include a value of Q representing the number of second downlink reference signals measured in the measurement relaxed state.

It can be understood that the downlink reference signals may be CSI-RS or SSB, each downlink reference signal corresponds to one beam, and the beam quality can be identified through measurement of the downlink reference signals, so that the corresponding beam is selected for downlink channel transmission. The index of the downlink reference signal can be used to identify a unique downlink reference signal on the cell and a beam corresponding to the reference signal.

Relaxing the number of measurements of cells refers to reducing the number of measured cells. For example, a terminal device not in a measurement relaxation state performs measurement for reference signals of M cells, a terminal device entering a measurement relaxation state performs measurement for reference signals of N cells, where N is smaller than M. The cell measured by the terminal device in the measurement relaxed state may be referred to as a first cell. Here, the cells measured by the terminal device may all be neighbor cells of the serving cell in which the terminal device is located. When the type of measurement relaxation includes a measurement number of relaxed cells, the radio link failure information may further include an identification of the measured first cell. The identification information may be represented by a set, for example, that is, the set includes N elements, each element being a Physical Cell ID (PCI) of each cell.

The number of measurement of the relaxation bin means that the number of measured bins is reduced. For example, a terminal device not in a measurement relaxed state measures M frequency points, and a terminal device entering the measurement relaxed state measures N frequency points. Wherein N is less than M. The frequency point measured by the terminal device in the measurement relaxed state may be referred to as a first frequency point. When the type of measurement relaxation includes the measurement number of relaxation frequency points, the radio link failure information may further include information of the first frequency point. For example, the information of the first frequency point may be a set/list of measured frequency information, where the set includes N elements, and each element is frequency information.

As an optional implementation manner, the terminal device may receive first indication information sent by the network device, where the first indication information is used to instruct the terminal device to send measurement relaxation information. At this time, whether the terminal device reports the measurement relaxation information may be determined according to specific requirements of the network device, and when the network device instructs the terminal device to report, the terminal device sends the corresponding measurement relaxation information.

In the first embodiment of the present application, the terminal device indicates the type of measurement relaxation through the measurement relaxation information, and may further send specific parameters related to measurement relaxation in the radio link failure information. The network device can acquire the measurement relaxation type of the RRM measurement performed by the terminal device and also can acquire the value of the measurement parameter in the measurement relaxation state, so that configuration adjustment is performed according to the value of the measurement parameter, and the energy-saving performance and the mobility of the terminal device are ensured.

Second embodiment

The second embodiment is a possible implementation of the communication method described based on the second aspect. Fig. 6a is a flowchart of a communication method according to a second embodiment of the present application. Fig. 7 is a schematic view of a scenario provided in a second embodiment of the present application. The serving cell is shown in fig. 7 to comprise 8 beams, numbered 1-8, respectively. The neighbor cell also includes 8 beams numbered 1-8, respectively. The network device may transmit downlink signals on each beam. In fig. 7, the terminal device is in the serving cell and may measure neighbor cells based on mobility. For example, downlink reference signals on beams of neighboring cells are measured, thereby performing cell handover. The method of the second embodiment of the present application includes:

601: the method comprises the steps that terminal equipment determines minimization drive test information, wherein the minimization drive test information comprises measurement results of m downlink reference signals of an adjacent cell and indexes of the m downlink reference signals, the m downlink reference signals belong to n downlink reference signals, and the n downlink reference signals are measured downlink reference signals of the adjacent cell;

602: and the terminal equipment sends the MDT information to the network equipment.

First, a procedure of measuring n downlink reference signals of a neighboring cell by a terminal device in 601 will be described.

The terminal device may make RRM measurements based on mobility. The terminal device in the connected state may measure the beam of the neighboring cell, or the terminal device in the idle state or the inactive state may measure the beam of the neighboring cell. The measurement result of the terminal equipment in the connection state can be reported through an Immediate MDT mechanism in the minimization of drive test, and the measurement result of the terminal equipment in the idle state can be reported through a Logged MDT mechanism in the minimization of drive test.

In fig. 7, the serving cell includes 8 beams, and the neighboring cell includes 8 beams, and the terminal device may measure the downlink reference signal on each beam to determine the corresponding beam quality. The downlink reference signal of the neighboring cell measured by the terminal device may be referred to as a first downlink reference signal. For example, the terminal device may measure downlink reference signals on 8 beams of the neighboring cell, where the value of n is 8. Optionally, the terminal device may also measure only downlink reference signals of partial beams on the neighboring cell, for example, only downlink reference signals corresponding to beams 3-7 are measured, and at this time, the value of n is 5.

The terminal device may send the measurement result of the downlink reference signal of the neighboring cell to the network device through the minimization of drive test information. For example, the measurement result of the downlink reference signal collected by the idle terminal device may send the minimization of drive test information to the network device through the Logged MDT mechanism.

Optionally, the terminal device may send only a part of the measurement results, for example, when the terminal device measures the downlink reference signals on the beams 1 to 8, the terminal device may send only the measurement results of 1 to 5, and at this time, the value of m is 5. It is to be understood that the set of m downlink reference signals is a subset of the set of n downlink reference signals.

The terminal device may also send measurement results of all measured downlink reference signals, and still take the example that the terminal device measures the downlink reference signals on the beams 1 to 8, at this time, the value of n is 8. The terminal device may send the measurement results of the downlink reference signals corresponding to the beams 1 to 8 to the network device, and at this time, the value of m is also 8. Both m and n are natural numbers, the relationship of m and n may be expressed as m being less than or equal to n. And the maximum value that n can take is the total number of the downlink reference signals of the adjacent cells measured by the terminal equipment.

In the second embodiment of the present application, the minimization of drive test information may further include indexes of m downlink reference signals. And reporting the measurement result of the beam level by sending the indexes of the m downlink reference signals in the MDT information.

Alternatively, the downlink reference signal of the neighboring cell measured by the terminal device may be referred to as a first downlink reference signal. For example, the terminal device may measure downlink reference signals on 8 beams of the neighboring cell, where the downlink reference signals corresponding to the beams 1-8 are referred to as first downlink reference signals. The first downlink reference signal in the first downlink reference signal, for which the terminal device reports the measurement result, may be referred to as a second downlink reference signal. For example, when the terminal device measures the downlink reference signals on the beams 1 to 8, the terminal device may only send the measurement results of 1 to 5, and at this time, the downlink reference signal corresponding to the beam 1 to 8 may be referred to as a first downlink reference signal, and the downlink reference signal corresponding to the beam 1 to 5 may be referred to as a second downlink reference signal, so that the second downlink reference signal refers to the first downlink reference signal for which the terminal device has reported the measurement results. It is to be understood that the set of second downlink reference signals is a subset of the set of first downlink reference signals. In this case, the downlink reference signal of the neighboring cell measured by the terminal device is referred to as a first downlink reference signal, and the first downlink reference signal corresponding to the measurement result transmitted to the network device among the measurement results of the first downlink reference signal is referred to as a second downlink reference signal. The first downlink reference signal and the second downlink reference signal do not represent different kinds of reference signals.

The values of n, m, and the relationship between m and n will be described in the following ways.

The method I comprises the following steps: the value of n is equal to the total number of the downlink reference signals of the adjacent cell measured by the terminal equipment, and the value of m is 1.

In the case of the first mode, the value of n may be the same as the total number of the measured downlink reference signals of the neighboring cell, as shown in fig. 7, the value of n may be 8, that is, at this time, the terminal device measures all the downlink reference signals of the neighboring cell. Moreover, the terminal device may report only the measurement result of the downlink reference signal with the best signal quality, for example, the measurement result of the downlink reference signal corresponding to the beam 4 and the index information to the network device, where the value of m is 1.

The second method comprises the following steps: the value of n is equal to the total number of the downlink reference signals of the adjacent cells measured by the terminal equipment, and the value of m is more than 1 and less than n.

In the case of the second method, the value of n may be the same as the total number of the measured downlink reference signals of the neighboring cell, as shown in fig. 7, the value of n may be 8, that is, at this time, the terminal device measures all the downlink reference signals of the neighboring cell. Moreover, the terminal device may only report the measurement results of the plurality of downlink reference signals with the best signal quality, but may not report all the measurement results. For example, the measurement results of the downlink reference signals corresponding to the beam 4 and the beam 5 and the index information are reported to the network device, and the value of m is 2 at this time.

The third method comprises the following steps: the value of n is less than the total number of the downlink reference signals of the adjacent cells measured by the terminal equipment, and the value of m is 1.

In the third case, the value of n may be smaller than the total number of the measured downlink reference signals of the neighboring cell, as shown in fig. 7, the terminal device may only measure beams 3-6 of the neighboring cell, and the value of n is 4 at this time, that is, the terminal device measures part of the downlink reference signals of the neighboring cell at this time, that is, the terminal device performs measurement relaxation on the measurement of the neighboring cell at this time. Moreover, the terminal device may report only the measurement result of the downlink reference signal with the best signal quality, for example, the measurement result of the downlink reference signal corresponding to the beam 4 and the index information to the network device, where the value of m is 1.

The method is as follows: the value of n is less than the total number of the downlink reference signals of the adjacent cells measured by the terminal equipment, and the value of m is more than 1 and less than n.

In the case of the fourth mode, the value of n may be smaller than the total number of the measured downlink reference signals of the neighboring cell, as shown in fig. 7, the terminal device may only measure beams 3 to 6 of the neighboring cell, and the value of n is 4 at this time, that is, the terminal device measures part of the downlink reference signals of the neighboring cell at this time, that is, the terminal device performs measurement relaxation on the measurement of the neighboring cell at this time. Moreover, the terminal device may only report the measurement results of the plurality of downlink reference signals with the best signal quality, but may not report all the measurement results. For example, the measurement results of the downlink reference signals corresponding to the beam 4 and the beam 5 and the index information are reported to the network device, and the value of m is 2 at this time.

The network equipment can acquire the quality condition of one or more beams on the adjacent cell measured by the terminal equipment according to the minimization drive test information reported by the terminal equipment, and can establish the incidence relation between the beams of the adjacent cell and the serving cell according to the information, thereby optimizing the measurement relaxation of beam measurement. This will be specifically explained below by way of example.

Referring to fig. 7, the terminal device measures beams 1 to 8 of the neighboring cell, and transmits all the measurement results of beam 4 to the network device through the minimization of drive test information, where n is 8,m and is 1. Beam 4 can be considered to be the best quality beam in the measurement. The measurement result reported by the terminal device is the measurement result of the downlink reference signal corresponding to the beam 4. The minimization of drive test information also includes an index of a downlink reference signal corresponding to the beam 4, and information obtained by the network device according to a result reported by the terminal device is shown in table 2.

Table 2: index and measurement result of second downlink reference signal of adjacent cell

Index of downlink reference signal	Measurement results
Downlink reference signal 2 corresponding to beam 4	Measurement result 2

Meanwhile, the terminal device reports the measurement result of the serving cell, and the measurement result of the terminal device on the serving cell is shown in table 3.

Table 3: index and measurement result of serving cell downlink reference signal

Index of downlink reference signal	Measurement results
Downlink reference signal 1 corresponding to beam 1	Measurement result 1
Downlink reference signal 2 corresponding to beam 2	Measurement result 2

The network device can know that the beams with the best quality in the serving cell are the beam 1 and the beam 2 and the beam with the best quality in the neighbor cell is the beam 4 according to the measurement result of the neighbor cell and the measurement result of the serving cell. Thus, the network device may associate

beams

1 and 2 of the serving cell with beam 4 of the neighbor cell. For terminal devices subsequently within the coverage of

beams

1 and 2 of the serving cell, the network device may instruct the terminal device to measure only beam 4 of the neighboring cell, and not to measure other beams of the neighboring cell, so as to optimize measurement relaxation of beam measurement.

As an optional implementation manner, the terminal device may receive first indication information sent by the network device, where the first indication information is used to determine the second downlink reference signal. Fig. 6b is a flowchart of another communication method provided in the second embodiment of the present application, and as shown in fig. 6b, the method further includes 600: the network device sends minimization of drive test configuration information to the terminal device, and the terminal device may send the minimization of drive test information according to the minimization of drive test configuration information, where the minimization of drive test information may include the first indication information.

In the second embodiment of the present application, the terminal device sends the measurement results of m downlink reference signals and the indexes of the m downlink reference signals through the minimization of drive test information. The m downlink reference signals may be determined according to the first indication information, and the terminal device may determine which m downlink reference signals of the n downlink reference signals measured by the terminal device are to be measured according to the first indication information, and send the measurement result and the corresponding index to the network device.

As an optional implementation manner, the first indication information may indicate a first threshold, and the reported m downlink reference signals are downlink reference signals whose measurement result is greater than or equal to the first threshold among the measured n downlink reference signals. The first threshold may be set according to a measurement parameter of the downlink reference signal. The measurement of the downlink reference signal may include measurement of one or more of the following parameters: reference Signal Received Power (RSRP), reference Signal Received Quality (RSRQ), signal To Interference and Noise Ratio (SINR), signal To Noise Ratio (SNR), and the like. A larger value of the above parameter represents a better measurement result and thus a better quality of the characterizing beam. Taking the measurement parameter of the downlink reference signal as the reference signal received power as an example, the terminal device measures the reference signal received power of the downlink reference signal corresponding to the beams 1-8 of the neighboring cell. In the measurement results of the downlink reference signals corresponding to the beams 1 to 8, the reference signal received power of the downlink reference signals corresponding to the

beams

4 and 5 is greater than or equal to the first threshold, and at this time, the reported m downlink reference signals are the downlink reference signals corresponding to the

beams

4 and 5. The first threshold may be a threshold characterizing the quality of the measurement result, and it may be considered that the measurement result meeting the first threshold is a downlink reference signal with a better measurement result, which represents that the beam quality corresponding to the downlink reference signal is better, and since the beam is transmitted in a specific direction, the better the beam quality indicates that the terminal device is closer to the coverage of the beam or the terminal device is under the coverage of the beam. Or measuring multiple parameters, and reporting the measurement result and index of the downlink reference signal when the multiple parameters all meet corresponding threshold values.

As an optional implementation manner, the first indication information may indicate the second threshold, and the reported m downlink reference signals are downlink reference signals whose measurement result is smaller than the second threshold among the measured n downlink reference signals. The second threshold may also be set according to a measurement parameter of the downlink reference signal. The measurement of the downlink reference signal may include measurement of one or more of the following parameters: RSRP, RSRQ, SINR, SNR, or the like. When the m reported downlink reference signals are downlink reference signals smaller than a second threshold, the terminal device reports a beam with a poor measurement result, and since the beam is transmitted in a specific direction, the worse the beam quality is, the terminal device is far away from the coverage of the beam, and the network device can also establish an association relationship with the beam of the serving cell according to the measurement result, for example, in the measurement results of the downlink reference signals corresponding to the beams 1 to 8, the measurement results of the downlink reference signals corresponding to the beams 1 to 3 and 6 to 8 are smaller than the second threshold, and at this time, the m reported downlink reference signals are the downlink reference signals corresponding to the beams 1 to 3 and 6 to 8. The measurement results of the beams 1 to 3 and the beams 6 to 8 of the neighbor cell are poor, the beams with better quality of the serving cell are the beam 1 and the beam 2, and the network equipment can establish the association relationship between the beams of the serving cell and the beams of the neighbor cell according to the reported beam measurement results and the beam indexes. It is understood that the association relationship may be a geographical location relationship obtained according to the beam quality, and since the beam is transmitted in a specific direction, the worse the beam quality indicates that the terminal device is far away from the coverage of the beam, and the better the beam quality indicates that the terminal device is close to the coverage of the beam. For example, the network device knows that the beams with better quality in the serving cell are beam 1 and beam 2 and the beams with better quality in the neighboring cell are beam 4 and beam 5 according to the reported measurement result and the beam index, so it can be concluded that beam 1 and beam 2 in the serving cell and beam 4 and beam 5 in the neighboring cell are closer in geographic location; for example, the network device knows that the beams with better quality in the serving cell are beam 1 and beam 2, and the beams with worse quality in the neighboring cells are beam 1 to beam 3 and beam 6 to beam 8, so it can be concluded that beam 1 and beam 2 in the serving cell, and beam 1 to beam 3 and beam 6 to beam 8 in the neighboring cells are separated from each other in a geographical location.

As an alternative, the first indication information may indicate the value of m. The measurement results of the n downlink reference signals measured by the terminal device may be sorted in a descending order, and the measurement results of the m downlink reference signals before sorting may be sent to the network device. For example, the terminal device measures downlink reference signals corresponding to beams 1-8 of the neighboring cell, where n is 8. And sequencing the measurement results of the downlink reference signals corresponding to the beams 1-8. For example, the RSRP measurement result values may be sorted, and the descending order refers to sorting the RSRP measurement result values from large to small, and the larger the RSRP measurement result value is, the better the measurement result is. Assume that the ordering results are beam 4, beam 5, beam 6, beam 3, beam 7, beam 2, beam 8, beam 1. The value of m indicated by the first indication information is 2, and at this time, the m downlink reference signals are downlink reference signals corresponding to the beam 4 and the beam 5.

As an alternative, the first indication information may indicate the value of m. The measurement results of n downlink reference signals measured by the terminal device may be sorted in ascending order, and the measurement results of m downlink reference signals before sorting may be sent to the network device. For example, the terminal device measures downlink reference signals corresponding to beams 1-8 of the neighboring cell, where n is 8. And sequencing the measurement results of the downlink reference signals corresponding to the beams 1-8. For example, the RSRP measurement values may be sorted, where ascending means that the values are sorted from small to large RSRP measurement values, and a smaller RSRP measurement value represents a worse measurement result. Assume that the ordering results are beam 1, beam 8, beam 2, beam 7, beam 3, beam 6, beam 5, beam 4. The value of m indicated by the first indication information is 6, and in this case, the m downlink reference signals are downlink reference signals corresponding to beam 1, beam 8, beam 2, beam 7, beam 3, and beam 6. The terminal device reports the beam with the poor measurement result, and the network device may also establish an association relationship with the beam of the serving cell according to the measurement result, for example, in the measurement results of the downlink reference signals corresponding to the beams 1 to 8, the measurement results of the downlink reference signals corresponding to the beams 1 to 3 and the beams 6 to 8 are smaller than a second threshold, and at this time, the reported m downlink reference signals are the downlink reference signals corresponding to the beams 1 to 3 and the beams 6 to 8. The measurement results of the beams 1 to 3 and 6 to 8 of the neighboring cell are poor, the beams with better quality of the serving cell are the beam 1 and the beam 2, and the network device can establish an association relationship between the beam 1 and the beam 2 of the serving cell and other beams of the neighboring cell except the beam 1 to 3 and the beam 6 to the beam 8.

By adopting the first indication information to indicate the first threshold value or the value of m, the measurement results of the downlink reference signals of the neighboring cells can be screened. The network equipment can acquire index information of the best-quality beam on the adjacent cell measured by the terminal equipment according to the minimization drive test information reported by the terminal equipment, and can establish the incidence relation between the beams of the adjacent cell and the serving cell according to the information, thereby optimizing the measurement relaxation of the beam level.

An alternative embodiment for optimizing the beam level measurement relaxation is to configure the beam level measurement relaxation for the terminal device to reduce unnecessary beam measurements according to the association between the beams of the neighbor cell and the serving cell. For example, the network device knows that beam 1 of the serving cell is closer to

beams

4 and 5 of the neighboring cells in the geographical location according to the association relationship between the beams of the neighboring cells and the serving cell, and for the terminal device under the coverage of beam 1 of the serving cell, the terminal device may be configured to measure only beam 4 and beam 5 of the neighboring cell. As an optional implementation manner, the first indication information is further used to indicate the terminal device to send indexes of m downlink reference signals. When the first indication information indicates the terminal device to report the indexes of the m downlink reference signals, the terminal device sends the measurement result of each downlink reference signal and the corresponding index information thereof to the network device according to the indication of the network device. Otherwise, the terminal device may choose to only report the average measurement result of each downlink reference signal, and does not send the index information.

In the second embodiment of the present application, the terminal device sends the indexes of m downlink reference signals in the minimization of drive test information, and the network device may establish an association relationship between beams of the neighboring cell and the serving cell according to the information, thereby optimizing measurement relaxation of beam measurement.
