[0054] The beneficial effects of the communication methods provided in the second aspect and the various possible designs of the second aspect can be found in the first aspect and the various possible implementations of the first aspect, and will not be repeated here.

[0055] In any of the first to second aspects and any possible design of such aspect, the triggering condition includes the second measurement result being better than the first measurement result, including: the second measurement result is greater than the first measurement result, and the difference between the second measurement result and the first measurement result is greater than a set value.

[0056] In any of the first to second aspects and any possible design of such aspect, the set value is related to the transmission power information of the second reference signal, the transmission power information of the first reference signal, and the threshold.

[0057] Alternatively, the first measurement result is the actual measurement result of the first reference signal scaled according to the transmission power information of the first reference signal; the second measurement result is the actual measurement result of the second reference signal scaled according to the transmission power information of the second reference signal; the set value is a threshold.

[0058] In any of the first to second aspects described above, and in any possible design of that aspect, the threshold is configured by the network device; or, the threshold is predefined.

[0059] In any of the first to second aspects and any possible design of such aspect, the second measurement resource includes reference signals from multiple cells, the reference signals in the same cell have the same threshold, and the reference signals in different cells have different thresholds.

[0060] In any of the first to second aspects and any possible design of such aspect, when the cell corresponding to the reference signal in the first measurement resource is a serving cell, the threshold is a first value; when the cell corresponding to the reference signal in the first measurement resource is a non-serving cell, the threshold is a second value.

[0061] In any of the first to second aspects and any possible design of such aspect, the channel state information report includes at least the identifier of the second measurement result and the second reference signal corresponding to the second measurement result.

[0062] In any of the first to second aspects and any possible design of such aspect, when the channel state information report includes multiple measurement results, the second measurement result is represented by an absolute measurement value, and the remaining measurement results are represented by differential measurement values. The differential measurement value is the difference between the measurement result of the reference signal corresponding to the remaining measurement result and the second measurement result.

[0063] In any of the first to second aspects and any possible design of such aspect, in the channel state information report, the ranking priority of the measurement results of the reference signal belonging to the same cell as the second reference signal is higher than the ranking priority of the measurement results of the reference signals of other cells.

[0064] In any of the first to second aspects and in any possible design of such aspect, the channel state information report also includes a first measurement result.

[0066] Thirdly, a communication method is provided, which is applied to a terminal device, and the method includes:

[0067] Send a channel state information report to the network device. The channel state information report includes a second measurement result of the second reference signal and a third measurement result of the third reference signal.

[0068] The ranking priority of the second measurement result is higher than that of the third measurement result;

[0069] The second reference signal meets the triggering condition, while the third reference signal does not.

[0070] Based on the method provided in this application, the terminal device can carry in the CSI report a second measurement result of the reference signal that meets the triggering conditions, as well as the measurement result of the reference signal that does not meet the triggering conditions. The measurement result of the reference signal that meets the triggering conditions has a higher priority than the measurement result of the reference signal that does not meet the triggering conditions, which improves the reliability of the measurement result of the reference signal that meets the triggering conditions. Therefore, the terminal device can send a CSI report to the network device, enabling the network device to prioritize the signal quality of the reference signal that meets the triggering conditions. This helps the network device compare the signal quality of the current serving link and candidate serving connections, allowing the network device to perform resource allocation, scheduling decisions, beam management, handover control, and other operations within or between cells, ensuring the communication continuity and quality of the terminal device.

[0071] The difference between the first and third aspects is as follows: The first aspect focuses on the configuration and triggering of CSI reports. The terminal device only initiates a CSI report when the triggering conditions are met. The third aspect focuses on the content and format of the CSI report. The CSI report includes: the second measurement result of the reference signal that meets the triggering conditions, and the measurement result of the reference signal that does not meet the triggering conditions, with the ranking priority of the measurement result of the reference signal that meets the triggering conditions being higher than that of the measurement result of the reference signal that does not meet the triggering conditions.

[0072] Fourthly, a communication method is provided, which is applied to a network device, and the method includes:

[0073] The receiving terminal device sends a channel state information report, which includes a second measurement result of a second reference signal and a third measurement result of a third reference signal.

[0074] The ranking priority of the second measurement result is higher than that of the third measurement result;

[0075] The second reference signal meets the triggering condition, while the third reference signal does not.

[0076] The beneficial effects of the communication methods provided in the fourth aspect and the various possible designs of the fourth aspect can be seen in the beneficial effects of the third aspect and the various possible implementations of the third aspect, and will not be repeated here.

[0077] In any of the third to fourth aspects and any possible design of such aspect, the second measurement result is represented by an absolute measurement value, and the third measurement result is represented by a differential measurement value, wherein the differential measurement value is the difference between the third measurement result and the second measurement result.

[0078] In any of the third to fourth aspects and any possible design of such aspect, in the channel state information report, the ranking priority of the measurement results of the reference signal belonging to the same cell as the second reference signal is higher than the ranking priority of the measurement results of the reference signal belonging to a different cell than the second reference signal.

[0082] The trigger condition is that the first measurement result is greater than the second measurement result.

[0083] In any of the third to fourth aspects mentioned above, and in any possible design of that aspect, the first measurement result has the lowest priority in ranking.

[0084] In any of the third to fourth aspects mentioned above, and in any possible design of such aspect, the first measurement result is represented by a differential measurement value, which is the difference between the first measurement result and the second measurement result.

[0119] The technical solutions of the embodiments of this application will be described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature.

[0120] In embodiments of this application, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes that element.

[0121] In the embodiments of this application, "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0122] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "set", "connected", and "linked" should be interpreted broadly, for example, as a fixed connection, a detachable connection, or an integral connection; those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0123] First, some of the terms used in this application will be explained below to facilitate understanding by those skilled in the art.

[0124] 1. Beam

[0125] A beam is a communication resource. A beam can be wide, narrow, or other types of beams. The technology used to form a beam can be beamforming or other techniques. Beamforming technology can specifically be digital beamforming, analog beamforming, or a hybrid digital / analog beamforming technology. Different beams can be considered different resources. The same or different information can be transmitted through different beams. Optionally, multiple beams with the same or similar communication characteristics can be considered as a single beam. A beam can include one or more antenna ports for transmitting data channels, control channels, and detection signals, etc. For example, a transmit beam can refer to the signal strength distribution in different directions of space after a signal is transmitted through an antenna, and a receive beam can refer to the signal strength distribution in different directions of space of the wireless signal received from the antenna. It is understood that one or more antenna ports forming a beam can also be considered as a set of antenna ports.

[0126] When using low-frequency or mid-frequency bands, signals can be transmitted omnidirectionally or through a wide angle. When using high-frequency bands, thanks to the smaller carrier wavelength of high-frequency communication systems, antenna arrays consisting of many antenna elements can be arranged at both the transmitting and receiving ends. The transmitting end transmits signals with a certain beamforming weight, making the transmitted signal form a spatially directional beam. At the same time, the receiving end uses an antenna array with a certain beamforming weight to receive the signal, which can improve the received power at the receiving end and counteract path loss.

[0127] 2. Reference signal (RS)

[0128] According to the Long Term Evolution (LTE) / New Radio (NR) protocols, at the physical layer, uplink communication includes the transmission of uplink physical channels and uplink signals. The uplink physical channels include: Random Access Channel (PRACH), Physical Uplink Control Channel (PUCCH), and Physical Uplink Shared Channel (PUSCH), etc. Uplink signals include: Uplink Sounding Reference Signal (SRS), Uplink Control Channel Demodulation Reference Signal (PUCCH-DMRS), Uplink Data Channel Demodulation Reference Signal (PUSCH-DMRS), Uplink Phase Noise Tracking Reference Signal (PTRS), and Uplink Positioning Signal, etc. Downlink communication includes the transmission of downlink physical channels and downlink signals.The downlink physical channels include the physical broadcast channel (PBCH), the physical downlink control channel (PDCCH), and the physical downlink shared channel (PDSCH). Downlink signals include the primary synchronization signal (PSS) / secondary synchronization signal (SSS), the downlink control channel demodulation reference signal (PDCCH-DMRS), the downlink data channel demodulation reference signal (PDSCH-DMRS), the downlink phase noise tracking reference signal (PTRS), the channel status information reference signal (CSI-RS), the cell reference signal (CRS), the time / frequency tracking reference signal (TRS), and the LTE / NR positioning signal (positioning RS). The PSS, SSS, and PBCH together constitute the synchronization signal block (SSB).

[0129] 3. Measurement Resources and Reference Signals

[0130] Measurement resources can be viewed as a collection of reference signals. Measurement resources may include one or more reference signals. Measurement resources may include reference signals from the same cell or from different cells. A single cell may include one or more reference signals. Reference signals may be the uplink signals mentioned earlier, or they may be the downlink signals mentioned earlier.

[0131] 4. Service area, non-service area and adjacent area

[0132] A serving cell is the cell that currently provides service to a terminal device; that is, the cell with which the terminal device is communicating, receiving, and sending data. The signal quality of the serving cell directly affects the communication quality and performance of the terminal device.

[0133] A non-serving cell refers to a cell that is not currently providing services to terminal devices.

[0134] In some instances, a non-serving cell may be another cell that the terminal device can detect but has not established a connection with, i.e., a neighboring cell, in addition to the serving cell.

[0135] Neighboring cells typically overlap with non-serving cells. A neighboring cell refers to a cell that is geographically adjacent to the serving cell. Neighboring cells can be surrounding cells of the serving cell. Terminal devices will measure and monitor the signals of neighboring cells, but the terminal devices will not communicate, receive, or send data on the neighboring cells at this time.

[0136] Among them, the signal quality of non-serving cells is also important for network equipment to decide whether to perform cell handover, so as to ensure that terminal devices always connect to cells with good signal quality, thereby providing stable and high-quality communication services.

[0137] 5. Reference signal, serving cell and non-serving cell

[0138] Whether a reference signal originates from the serving cell can be determined in the following ways:

[0139] If the physical cell identity (PCI) associated with the reference signal is the same as the physical cell identity of the current serving cell, and the frequency of the reference signal is the same as the frequency of the cell-defining SSB of the current serving cell, then the reference signal originates from the serving cell.

[0140] If the physical cell identity (PCI) associated with the reference signal is different from that of the current serving cell, and / or if the frequency of the reference signal is different from the frequency of the cell definition SSB of the current serving cell, then the reference signal does not originate from the serving cell.

[0141] The physical cell identifier of the currently serving cell is determined by the cell definition SSB.

[0142] This application provides a communication method. The communication method of this application can be applied to a communication system, which may include, but is not limited to, wireless communication systems, such as narrowband Internet of Things (NB-IoT), Global System for Mobile Communications (GSM), Enhanced Data Rate for GSM Evolution (EDGE), Wideband Code Division Multiple Access (WCDMA), Code Division Multiple Access 2000 (CDMA2000), Time Division-Synchronization Code Division Multiple Access (TD-SCDMA), LTE systems, the 5th generation (5G) systems, the 6th generation (6G) systems, and future systems.

[0143] The scenarios for which this communication system is applicable may include, but are not limited to: terrestrial cellular communication, non-terrestrial network (NTN), satellite communication, high altitude platform station (HAPS) communication, vehicle-to-everything (V2X) communication, integrated access and backhaul (IAB) communication, and reconfigurable intelligent surface (RIS) communication.

Network device 20 can be a base station, an access point, an access network device, or a device in the access network that communicates with a wireless terminal through one or more sectors on the air interface (referred to as the air interface). Network device 20 can be used to convert received air frames to and from Internet Protocol (IP) packets, acting as a router between the wireless terminal and the rest of the access network, which may include an IP network. Network device 20 can also coordinate the attribute management of the air interface. For example, network device 20 can be a satellite, a drone, an evolved Node B (eNB or eNodeB) in LTE, a radio controller in a cloud radio access network (CRAN) scenario, or a terminal, relay station, or access point that performs base station functions in wearable devices or vehicle-mounted devices, vehicular to everything (V2X), device-to-device (D2D), and machine-to-machine (M2M) communications, or a base station in a 5G network, such as a gNB, or a base station in a future 6G network, or a network device in a future evolved public land mobile network (PLMN) network, and is not limited here.

[0146] Network device 20 may be a RAN node that connects user equipment 20 to the wireless network. Examples of RAN nodes include: gNB, transmission reception point (TRP), evolved Node B (eNB), home base station (e.g., home evolved Node B, or home Node B, HNB), baseband unit (BBU), or wireless fidelity (Wi-Fi) access point (AP), IAB, etc.

[0147] In a network architecture, network device 20 may include centralized unit (CU) nodes, distributed unit (DU) nodes, RAN devices including CU nodes and DU nodes, or RAN devices including control plane CU nodes (CU-CP nodes), user plane CU nodes (CU-UP nodes), and DU nodes.

[0148] CU and DU can be understood as a logical functional division of RAN nodes. CU and DU are connected via the F1 interface; CU can represent gNB and connect to the core network via the NG interface. Physically, CU and DU can be separate or deployed together; this application does not impose specific limitations on this. One CU can connect to one DU, or multiple DUs can share one CU, which can save costs and facilitate network expansion. The division of CU and DU can be based on the protocol stack. One possible approach is to deploy the radio resource control (RRC), service data adaptation protocol (SDAP), and packet data convergence protocol (PDCP) layers on the CU, and the remaining radio link control (RLC), media access control (MAC), and physical layers on the DU. This application does not completely limit the above protocol stack division method; other division methods are also possible.

[0149] Terminal device 10 may include one or more devices. Terminal device 10 is a device with wireless transceiver capabilities. Terminal device 10 can be a wireless terminal or a wired terminal. A wireless terminal can be a device providing voice and / or other service data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The wireless terminal can communicate with one or more core networks via a radio access network (RAN). The wireless terminal can be a mobile terminal, such as a mobile phone (or "cellular" phone) and a computer with a mobile terminal, for example, a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device that exchanges voice and / or data with the radio access network. Examples include personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), drones, wearable devices, and terminals in vehicle-to-everything (V2X) networks. A wireless terminal can also be referred to as a system, subscriber unit, subscriber station, mobile station (MS), mobile station, remote station, remote terminal, access terminal, user terminal, user agent, user device or user equipment, user equipment (UE), terminal unit, terminal station, remote station, mobile device, terminal, wireless communication equipment, terminal agent, or terminal device, etc., without limitation.

[0150] Access terminals can be cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, in-vehicle devices, wearable devices, terminal devices in 5G networks, 6G networks or future networks, or terminal devices in future evolved public land mobile networks (PLMNs), etc.

[0151] In addition, the terminal device 10 may use mobile operating systems such as Android, Linux, Windows, and iOS, and this application does not limit it in this regard.

[0152] Communication between network device 20 and terminal device 10, as well as between terminal devices 10 themselves, can be conducted using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication between network device 20 and terminal device 10, as well as between terminal devices 10 themselves, can be conducted using spectrum below 6 gigahertz (GHz), spectrum above 6 GHz, or both simultaneously. This application does not limit the spectrum resources used between network device 20 and terminal device 10.

[0153] In mobile communication, when network device 20 acts as the transmitter and terminal device 10 acts as the receiver, such as Figure 1 As shown, network device 20 can use multiple beams (Tx beams) with different orientations to transmit CSI-RS in different directions. Correspondingly, terminal device 10 can use multiple beams (Rx beams) with different orientations to receive CSI-RS transmitted from network device 20 in different directions.

[0154] Furthermore, network device 20 can also use a directional beam to transmit wireless signals. This application does not limit the number or direction of the beams used by network device 20. Correspondingly, terminal device 10 can also use a directional beam to receive wireless signals. This application does not limit the number or direction of the beams used by terminal device 10. It should be understood that... Figure 1 This is merely an illustrative example.

[0155] Therefore, terminal device 10 can measure various parameters of the serving cell and neighboring cells using the reference signal. The reference signal is used by terminal device 10 to measure downlink channel state, providing channel state information to network device 20. In this way, terminal device 10 can send a CSI report to network device 20 according to the network-side configuration information.

[0156] The network-side configuration information may include CSI report content and reference signal configuration information. CSI report content may include, but is not limited to: the type of CSI report, the number of cells requiring reporting, the number of reference signals required for each cell, and whether measurement information of the serving cell needs to be reported. Reference signal configuration information refers to the measurement resources configured on the network side, i.e., a resource set for a reference signal. Each reference signal resource in this set is determined by the SSB index and the configuration information associated with the SSB index. The associated configuration information may include: the physical cell index and the SSB's transmit power.

[0157] For a serving cell, the CSI report can help network devices understand the coverage and interference levels within the cell, enabling them to perform resource management, power control, and handover decisions to optimize the quality of communication services within the cell.

[0158] For neighboring cells, the CSI report can help network device 20 determine whether cell handover is necessary to ensure communication continuity and service quality for terminal device 10 during movement.

[0159] However, the above method results in significant overhead for terminal equipment to measure pilot signals and substantial delays in feedback reports.

[0160] The following issues may arise in measuring pilot overhead, thus increasing the overhead and processing difficulty of pilot measurement:

[0161] 1. The network-side configuration operation may be too complex or cumbersome, causing the terminal device 10 to process a large number of pilot signals.

[0162] 2. The resource allocation configured on the network side may be insufficient or unreasonable, causing the terminal device 10 to complete more measurement tasks within a limited time and resources.

[0163] Regarding feedback report latency, the following issues may exist, thus increasing the latency of feedback reports:

[0164] 1. The report feedback cycle configured on the network side may be long, which means that the terminal device 10 needs to wait a long time after collecting the CSI report before it can provide feedback.

[0165] 2. The uplink transmission resources configured on the network side may be limited, causing terminal device 10 to wait for available resources to send back the CSI report.

[0166] In view of the above problems, this application provides a communication method that can trigger beam reporting based on events. That is, once the terminal device detects an event, it can report a beam report, wherein the reporting time of the beam report depends on the time when the terminal device detects the event. It is evident that this method can reduce the overhead of measurement pilots and the feedback delay of beam reporting.

[0167] This event occurs when the terminal device detects that the signal quality of the second measurement resource (or candidate serving link) is better than the signal quality of the first measurement resource (or the current serving link) plus a preset value. The first measurement resource refers to the reference signal in the serving cell. The second measurement resource refers to the reference signal in the serving cell and / or the reference signal in a non-serving cell; the reference signal in the second measurement resource can be considered a candidate reference signal. The reference signal in the second measurement resource can originate from the same cell or from different cells.

[0168] The following embodiments of this application will be used to illustrate the concept of having Figure 1 Taking the terminal device 10 and network device 20 with the shown structures as examples, the communication method provided in this application will be described in detail with reference to the accompanying drawings and application scenarios.

[0169] Please see Figure 2 , Figure 2 This is an interactive flowchart illustrating a communication method provided in an embodiment of this application. The method is applied to a terminal device and a network device, wherein the terminal device can be... Figure 1 The communication equipment or devices in the communication equipment, network equipment can be Figure 1 The network device or device within the network device. For simplicity, let's take the example where the method is executed by a terminal device and a network device, such as... Figure 2 As shown, the communication method provided in this application may include:

[0170] S101. When the triggering conditions are met, the terminal device sends a channel status information report to the network device.

[0171] Accordingly, the network device receives the channel status information report sent by the terminal device.

[0172] Typically, a cell can transmit one or more reference signals, and the beams used to transmit different reference signals may be different to cover different areas. Based on this, the first measurement resource is the set of reference signals currently providing services to the terminal device. The cells corresponding to the reference signals in the first measurement resource include the serving cell.

[0173] Therefore, all reference signals in the first measurement resource originate from the serving cell. The first reference signal is included in the first measurement resource. The first reference signal may include one or more reference signals. Thus, the first reference signal originates from the serving cell. The first measurement result, used to indicate the measurement result of the first reference signal, can represent the signal quality of the serving cell and the signal quality of the first reference signal within the serving cell.

[0174] The measurement results mentioned in this application are used to indicate performance parameters of the reference signal, such as received signal strength (RSS), signal quality, and signal characteristics. Signal strength indicates the power of the received reference signal. Signal quality indicates the purity and reliability of the reference signal. Channel characteristics, such as multipath propagation, delay spread, and Doppler frequency domain, indicate the dynamic changes of the channel.

[0175] In some instances, the measurement results may include the signal-to-interference plus noise ratio (SINR) and / or the reference signal receiving power (RSRP).

[0176] It is evident that the first measurement resource can be the reference signal from the serving cell.

[0177] In some instances, the terminal device currently uses only one serving beam, which can transmit a single reference signal. Thus, the number of reference signals in the first measurement resource can be one.

[0178] In some instances, the terminal device may include multiple panels, which can serve simultaneously. At any given time, multiple beams may serve the terminal device. Multiple beams can transmit multiple reference signals. Thus, the number of reference signals in the first measurement resource can be multiple.

[0179] Furthermore, when the first measurement resource includes multiple reference signals, a second measurement resource can be configured for each reference signal. This allows the terminal device to compare the signal quality of each reference signal with that of the corresponding second measurement resource. Alternatively, the terminal device can select one reference signal from the multiple reference signals to compare its signal quality with that of the second measurement resource. Of course, this application includes, but is not limited to, the foregoing methods.

[0180] The second measurement resource can be viewed as a set of candidate reference signals, and the reference signals in the second measurement resource can be considered as candidate reference signals. The cells corresponding to the candidate reference signals can include multiple sources.

[0181] When the cell corresponding to the reference signal in the second measurement resource includes the serving cell, all reference signals in the second measurement resource originate from the serving cell. The second reference signal is included in the second measurement resource. The second reference signal may include one or more reference signals. Therefore, the second reference signal originates from the serving cell. The second measurement result, used to indicate the measurement result of the second reference signal, reflects the signal quality of the candidate reference signal in the serving cell, i.e., the signal quality of other beams in the serving cell.

[0182] Therefore, by using the first and second measurement results, the signal quality difference within the cell can be fed back.

[0183] When the reference signal in the second measurement resource corresponds to a non-serving cell, all reference signals in the second measurement resource originate from the non-serving cell. Therefore, the reference signal in the second measurement resource differs from the reference signal in the first measurement resource. The second reference signal is included in the second measurement resource. The second reference signal may include one or more reference signals. Thus, the second reference signal originates from the non-serving cell. The second measurement result, used to indicate the measurement result of the second reference signal, reflects the signal quality of the non-serving cell.

[0184] Therefore, by using the first and second measurement results, the signal quality difference between the segments can be fed back.

[0185] When the reference signal in the second measurement resource corresponds to a serving cell and a non-serving cell, a portion of the reference signal in the second measurement resource originates from the serving cell, and the remainder originates from the non-serving cell. Therefore, the reference signal from the serving cell in the second measurement resource partially overlaps with the reference signal in the first measurement resource. The second reference signal is included in the second measurement resource. This second reference signal may include one or more reference signals. Thus, the second reference signal originates from the serving cell and / or the non-serving cell. The second measurement result, used to indicate the measurement result of the second reference signal, reflects the signal quality of the serving cell and / or the non-serving cell.

[0186] Therefore, by using the first and second measurement results, the signal quality difference within the cell and / or the signal quality difference between cells can be fed back.

[0187] Based on the above description, the signal quality of the candidate reference signal may be better than that of the first reference signal. Therefore, the terminal device can determine whether the triggering condition is met.

[0188] The triggering conditions include: the second measurement result is better than the first measurement result.

[0189] In some instances, considering the parameters involved in the measurement results of the reference signal, in practice, the larger the value, the better the signal quality of the reference signal. Therefore, the trigger condition can be set as follows: the second measurement result is greater than the first measurement result, and the difference between the second measurement result and the first measurement result is greater than a set value.

[0190] Of course, in some instances, considering the parameters involved in the measurement results of the reference signal, it may be that the smaller the value, the better the signal quality of the reference signal. Therefore, the trigger condition can also be set as follows: the second measurement result is less than the first measurement result, and the difference between the second measurement result and the first measurement result is less than a set value.

[0191] For ease of explanation, this application uses the example of a trigger condition where the second measurement result is greater than the first measurement result, and the difference between the second measurement result and the first measurement result is greater than a set value.

[0192] When the triggering condition is met, there exists a candidate reference signal whose signal quality is better than that of the first reference signal, and the signal quality difference between the candidate reference signal and the first reference signal is large.

[0193] When the cell corresponding to the candidate reference signal is the serving cell, the signal quality of the candidate reference signal in the serving cell is better than that of the first reference signal in the serving cell. Furthermore, the signal quality difference between the first reference signal and the candidate reference signal in the serving cell is significant.

[0194] In other words, the signal quality of the candidate beams in the serving cell is better than that of the current serving beam in the serving cell, and there is a large difference in signal quality between the current serving beam and the candidate beams in the serving cell.

[0195] Therefore, by leveraging this larger gap, the triggering conditions can be prevented from occurring frequently, reducing the feedback overhead of CSI reports. Network devices can also control the frequency of CSI reports from terminal devices to some extent by configuring settings.

[0196] When the cell corresponding to the candidate reference signal is a non-serving cell, the signal quality of the non-serving cell is better than that of the serving cell between cells. Furthermore, the signal quality difference between serving and non-serving cells is significant.

[0197] Therefore, by leveraging this larger gap, the triggering conditions can be prevented from occurring frequently, reducing the feedback overhead of CSI reports. Network devices can also control the frequency of CSI reports from terminal devices to some extent by configuring settings.

[0198] When the cell corresponding to the candidate reference signal includes both serving and non-serving cells, the specific implementation details can be found in the descriptions of the two cases mentioned above, and will not be repeated here.

[0199] As can be seen, the second measurement resource can be a reference signal from a non-serving cell. Based on the triggering condition, if the signal quality of the non-serving cell is better than that of the serving cell, the terminal initiates a beam report to notify the network device of the occurrence of the triggering event.

[0200] Alternatively, the second measurement resource can be a reference signal from both the serving cell and non-serving cells. Based on the triggering conditions, if the signal quality of the non-serving cell is better than that of the serving cell, and / or, the signal quality of the candidate beam used in the serving cell is better than that of the currently used beam in the serving cell, then the terminal initiates a beam report to notify the network device of the occurrence of the triggering event.

[0201] Alternatively, the second measurement resource can be a reference signal from the serving cell. Based on the triggering condition, if the signal quality of the candidate beam in the serving cell is better than the signal quality of the currently used beam in the serving cell, the terminal initiates a beam report to notify the network device of the occurrence of the triggering event.

[0202] In summary, when the triggering conditions are met, the terminal device can simultaneously support intra-cell and inter-cell beam measurements, and then the terminal device can send a CSI report to the network device. The CSI report is used to indicate at least the second measurement result.

[0203] This enables network devices to perform resource allocation, scheduling decisions, beam management, and handover control based on CSI reports, thereby optimizing the performance of the communication system and ensuring the reliability and efficiency of data transmission.

[0204] For example, network devices use CSI reports to decide whether to switch terminal devices to other cells to ensure communication continuity and quality.

[0205] This application does not specify the specific transmission method for CSI reports. In some instances, channel state information reports are carried on the physical uplink control channel (PUCCH) or the physical uplink shared channel (PUSCH).

[0206] When the triggering conditions are not met, there will be no candidate reference signal as described above.

[0207] In one implementation, the signal quality of the first reference signal is better than that of the candidate reference signal.

[0208] When the cell corresponding to the candidate reference signal is the serving cell, the channel quality of the first reference signal in the serving cell is better than that of the candidate reference signal in the serving cell.

[0209] When the cell corresponding to the candidate reference signal is a non-serving cell, the signal quality of the serving cell is better than that of the non-serving cell between cells.

[0210] When the cell corresponding to the candidate reference signal includes both serving and non-serving cells, the specific implementation details can be found in the descriptions of the two cases mentioned above, and will not be repeated here.

[0211] In one implementation, the signal quality of the candidate reference signal is better than that of the first reference signal, and the signal quality difference between the candidate reference signal and the first reference signal is small.

[0212] When the cell corresponding to the candidate reference signal is the serving cell, the signal quality of the candidate reference signal in the serving cell is better than that of the first reference signal in the serving cell, and the signal quality difference between the first reference signal and the candidate reference signal in the serving cell is small.

[0213] However, this small difference is caused by measurement error or movement of the terminal device and cannot be used to determine that the signal quality of the candidate reference signal is better than that of the first reference signal.

[0214] When the cell corresponding to the candidate reference signal is a non-serving cell, the signal quality of the non-serving cell is better than that of the serving cell, and the signal quality difference between the serving cell and the non-serving cell is small.

[0215] However, this small difference is caused by measurement error or the movement of the terminal device and cannot be used to determine whether the signal quality of the non-serving cell is better than that of the serving cell.

[0216] In summary, when the triggering conditions are not met, the terminal device does not need to send a CSI report. Therefore, the terminal device can continue to determine whether the triggering conditions are met and repeat the above process.

[0217] The communication method provided in this application allows a terminal device to send a CSI report to a network device when a triggering condition is met, provided that a reference signal in the second measurement resource has a better signal quality than a first reference signal in the first measurement resource.

[0218] In addition, in S101, there are multiple ways to trigger a CSI report initiated by a terminal device.

[0219] In some possible scenarios, if there is at least one cell in the second measurement resource, and at least one reference signal in that cell satisfies the triggering condition, the terminal device can initiate a CSI report. That is, as long as there is at least one reference signal or a reference signal in one cell within the second measurement resource that satisfies the triggering condition, the terminal device will initiate a CSI report.

[0220] In this context, when multiple reference signals in the second measurement resource meet the triggering conditions, these reference signals can originate from the serving cell, or from both the serving cell and non-serving cells. Therefore, using a unified configuration method for triggering events within and between cells helps reduce signaling overhead.

[0221] In some possible scenarios, the second measurement resource must contain at least N cells, and each of these N cells must have at least one reference signal that satisfies the triggering condition for the terminal device to initiate a CSI report. In other words, the second measurement resource must have reference signals from at least N cells that satisfy the triggering condition for the terminal device to initiate a CSI report. The value of N can be configured through the network device. When the network device does not configure a value for N, the default value is N = 1.

[0222] Based on the above description, the setting value can be set by taking into account factors such as the signal transmission difference between the first reference signal and the candidate reference signal, as well as the signal quality difference caused by different cells.

[0223] In some instances, the setpoint is related to the transmission power information of the reference signal in the first measurement resource, the transmission power information of the reference signal in the second measurement resource, and a threshold.

[0224] The transmission power information of the reference signal is used to indicate the transmission power of the reference signal. The transmission power of the reference signal is the transmission power of a specific signal set to enable the terminal device to measure and estimate the channel state. That is, the network device transmits a reference signal at a certain power, and after receiving the reference signal, the terminal device uses it to measure and analyze channel characteristics, such as signal attenuation, interference level, and multipath propagation, thereby estimating the channel state. The transmission power of the reference signal is relatively stable, facilitating accurate measurement and estimation of the channel state by the terminal device. The setting of the reference signal's transmission power affects the accuracy and precision of the terminal device's channel state measurement. Typically, reference signals from the same cell have the same transmission power. Of course, reference signals from the same cell can also have different transmission powers. This application does not limit the specific implementation of the reference signal's transmission power information. In some instances, the transmission power information of the reference signal can be the absolute value of the reference signal's transmission power. Generally, the reference signal can be a broadcast signal. In some instances, the transmission power information of the reference signal can be a relative value of its transmission power, which refers to the difference between the transmission power of the reference signal and the transmission power of a certain signal. Typically, this certain signal can be a broadcast signal.

[0225] In some implementations, the set value can be the sum of an offset and a threshold. This offset is the difference between the transmission power of the reference signal in the second measurement resource and the transmission power of the reference signal in the first measurement resource; that is, the offset is the difference between the transmission power of the candidate reference signal and the transmission power of the first reference signal. For example, the offset can be the transmission power of the reference signal in the second measurement resource minus the transmission power of the reference signal in the first measurement resource. Alternatively, the offset can be the result of other operations performed between the transmission power of the reference signal in the second measurement resource and the reference signal in the first measurement resource. Here, the offset can also be called the offset difference.

[0226] For example, the transmission power of the first reference signal is P1, the transmission power of the candidate reference signal is P2, and the threshold is T0. Then, the setpoint T = P2 - P1 + T0.

[0227] Specifically, when the transmission power of the candidate reference signal is the same as that of the first reference signal, the offset is 0. In this case, the set value is the threshold. When the transmission power of the candidate reference signal is different from that of the first reference signal, the set value consists of two parts: one part is the offset, i.e., P2-P1, and the other part is the threshold.

[0228] For example, suppose the first measurement result is RSRP1 of the first reference signal, and the second measurement result is RSRP2 of the candidate reference signal. Then, the triggering condition is: RSRP2 > RSRP1 + T = RSRP1 + P2 - P1 + T0.

[0229] When the transmission power of the candidate reference signal is the same as that of the first reference signal, the offset is 0, and the triggering condition is: RSRP2 > RSRP1 + T = RSRP1 + T0.

[0230] When the aforementioned triggering conditions are met, the candidate reference signal becomes the second reference signal. When the aforementioned triggering conditions are not met, the candidate reference signal does not become the second reference signal.

[0231] For example, suppose the first measurement result is SINR1 of the first reference signal, and the second measurement result is SINR2 of the candidate reference signal. Then, when the transmission power of the candidate reference signal is the same as that of the first reference signal, the offset is 0, and the triggering condition is: SINR2 > SINR1 + T = SINR1 + T0. When the transmission power of the candidate reference signal is different from that of the first reference signal, the triggering condition is: SINR2 > SINR1 + T = SINR1 + P2 - P1 + T0.

[0232] In some instances, the set value is a threshold, the first measurement result is the actual measurement result of the first reference signal scaled according to the transmission power information of the first reference signal, and the second measurement result is the actual measurement result of the second reference signal scaled according to the transmission power information of the second reference signal.

[0233] The first measurement result is related to the actual measurement result of the first reference signal and the transmission power information of the first reference signal. For example, the first measurement result can be the actual measurement result of the first reference signal minus the transmission power information of the first reference signal. Alternatively, the first measurement result can be the result of performing other calculations on the actual measurement result of the first reference signal and the transmission power information of the first reference signal.

[0234] The second measurement result is related to the actual measurement result of the second reference signal and the transmission power information of the second reference signal. For example, the second measurement result can be the actual measurement result of the second reference signal minus the transmission power information of the second reference signal. Alternatively, the second measurement result can be the result of other calculations performed on the actual measurement result of the second reference signal and the transmission power information of the second reference signal.

[0235] For example, the transmission power of the first reference signal is P1, the transmission power of the candidate reference signal is P2, and the threshold is T0. The actual measurement result of the first reference signal is RSRP1, and the actual measurement result of the second reference signal is RSRP2. Then, the first measurement result is the scaled result of the actual measurement result of the first reference signal based on the transmission power information of the first reference signal, such as RSRP1 - P1. The second measurement result is the scaled result of the actual measurement result of the first reference signal based on the transmission power information of the second reference signal, such as RSRP2 - P2. Therefore, the triggering condition is RSRP2 - P2 > RSRP1 - P1 + T0.

[0236] When the transmission power of the candidate reference signal is the same as that of the first reference signal, the triggering condition is: RSRP2 > RSRP1 + T0, that is, the first measurement result is the actual measurement result of the first reference signal and the second measurement result is the actual measurement result of the second reference signal.

[0237] For example, the transmission power of the first reference signal is P1, the transmission power of the candidate reference signal is P2, and the threshold is T0. The actual measurement result of the first reference signal is SINR1, and the actual measurement result of the second reference signal is SINR2. Then, the first measurement result is the scaled result of the actual measurement result of the first reference signal based on the transmission power information of the first reference signal, such as SINR1-P1. The second measurement result is the scaled result of the actual measurement result of the first reference signal based on the transmission power information of the second reference signal, such as SINR2-P2. Therefore, the triggering condition is SINR2-P2>SINR1-P1+T0.

[0238] When the transmission power of the candidate reference signal is the same as that of the first reference signal, the triggering condition is: SINR2 > SINR1 + T0, that is, the first measurement result is the actual measurement result of the first reference signal and the second measurement result is the actual measurement result of the second reference signal.

[0239] In some embodiments, when the terminal device sends a channel state information report to the network device when the triggering condition is met, the transmission power of the reference signal of the first measurement resource is the same as the transmission power of the reference signal of the second measurement resource.

[0240] When the aforementioned triggering conditions are met, the candidate reference signal becomes the second reference signal. When the aforementioned triggering conditions are not met, the candidate reference signal does not become the second reference signal.

[0241] Based on the foregoing description, the terminal device needs to know the transmission power of the reference signal in the first measurement resource and the transmission power of the reference signal in the second measurement resource.

[0242] Prior to S101, the network device may inform the terminal device in advance of the transmission power of the reference signal in the first measurement resource and the transmission power of the reference signal in the second measurement resource.

[0243] Next, let's continue combining Figure 2 The specific implementation method of the above process will be described in detail.

[0244] like Figure 2 As shown, the communication method of this application may further include:

[0245] S100, the network device sends the first configuration information to the terminal device.

[0246] Accordingly, the terminal device receives the first configuration information sent by the network device.

[0247] When S100 needs to be executed, the network device can send the first configuration information to the terminal device.

[0248] The first configuration information is used to indicate the transmission power information of the reference signal transmitted by the network device in the second measurement resource and the transmission power information of the reference signal transmitted by the network device in the first measurement resource.

[0249] Therefore, the terminal device can use the first configuration information to determine the transmission power of each reference signal in the first measurement resource and the transmission power of each reference signal in the second measurement resource, which helps to accurately determine whether the triggering condition is met.

[0250] In addition, if the transmission power of reference signals from the same cell is the same, then as another feasible implementation for measuring and estimating the channel state between cells, the first configuration information can be used to instruct the network device to transmit the transmission power information of each cell in the second measurement resource and the transmission power information of each cell in the first measurement resource.

[0251] Cell transmission power information indicates the cell's transmission power. Cell transmission power refers to the total transmit power used by the cell to transmit all signals, including data, control information, and reference signals. The cell's transmission power can be dynamically adjusted based on factors such as cell load, coverage requirements, and interference levels. Setting the cell's transmission power affects its coverage area, equipment capacity, and the level of interference to neighboring cells.

[0252] Typically, there is a certain ratio or relationship between the transmission power of a cell and the transmission power of the reference signal within the cell. As the transmission power of the cell is adjusted, the transmission power of the reference signal will also change accordingly to maintain this ratio or relationship.

[0253] Therefore, the terminal device can use the first configuration information and the mentioned ratio or relationship to determine the transmission power of the reference signal corresponding to each cell in the first measurement resource based on the transmission power of each cell in the first measurement resource, and determine the transmission power of the reference signal corresponding to each cell in the second measurement resource based on the transmission power of each cell in the second measurement resource, thereby helping to accurately measure and estimate the channel state between cells.

[0254] S100 is an optional step. If the transmission power information of the reference signals in the second measurement resource is consistent with the transmission power information of the reference signals in the first measurement resource, then the network device does not need to transmit the first configuration information to the terminal device. And / or, the protocol may predefine the first configuration information, or the transmission power information of each reference signal, or the method of obtaining the transmission power information of each reference signal. Therefore, before S101, the terminal device can obtain the first configuration information in advance, and the network device does not need to execute S100.

[0255] In summary, terminal devices can determine the transmission power of reference signals in measurement resources by using the configuration of network devices.

[0256] Based on the foregoing description, the terminal device also needs to know the threshold.

[0257] The threshold is configured by the network device. Alternatively, the threshold is a predefined value.

[0258] When the transmission power of the reference signal in the second measurement resource is the same as the transmission power of the reference signal in the first measurement resource, a threshold can be configured.

[0259] When the transmission power of the reference signal in the second measurement resource differs from the transmission power of the reference signal in the first measurement resource, multiple thresholds can be configured. These thresholds can be configured in various ways.

[0260] In some instances, each cell can be configured with a threshold. When the second measurement resource includes reference signals from multiple cells, the threshold corresponding to the reference signals within the same cell is the same, while the threshold corresponding to the reference signals in different cells is different.

[0261] Since the signal power of different cells is usually different, different thresholds can be set. The threshold corresponding to the reference signal in a cell can be related to the cell's transmission power.

[0262] For example, if the threshold corresponding to the reference signal in cell 1 is less than the threshold corresponding to the reference signal in cell 2, then the transmission power of cell 1 can be higher than the transmission power of cell 2.

[0263] Since terminal devices have different priorities when accessing a cell, different thresholds can be set. Specifically, the threshold corresponding to the reference signal in the cell can be related to the priority of the terminal device accessing the cell.

[0264] For example, if the threshold corresponding to the reference signal in cell 1 is less than the threshold corresponding to the reference signal in cell 2, then the priority for terminal devices to access cell 1 can be higher than the priority for terminal devices to access cell 2.

[0265] In summary, the threshold can be set to different sizes depending on whether the cells are the same.

[0266] Therefore, when the first measurement resource and the second measurement resource originate from the same cell, the threshold is the threshold of that cell. When the first measurement resource originates from the first cell, the second measurement resource originates from the second cell, and the first and second cells are different, the threshold is the threshold of the second cell.

[0267] In some instances, a threshold is configured for each cell type. That is, one threshold is configured for the serving cell, and another threshold is configured for the non-serving cell.

[0268] When the cell corresponding to the reference signal in the first measurement resource is a serving cell, the threshold is a first value. When the cell corresponding to the reference signal in the first measurement resource is a non-serving cell, the threshold is a second value.

[0269] The first value and the second value are not equal. In some instances, the first value is less than the second value.

[0270] Because intra-cell handover with different beams (or different serving links) is more flexible than inter-cell handover with different beams (or different serving links), or intra-cell handover with different beams (or different serving links) has lower latency than inter-cell handover with different beams (or different serving links), the first threshold is lower than the second threshold. This results in a smaller threshold for the serving cell, reducing the frequency of cell handovers.

[0271] In summary, the threshold can be set to different sizes depending on the type of cell.

[0272] Therefore, when the first measurement resource and the second measurement resource originate from the same cell, the threshold is the threshold of that cell. When the first measurement resource originates from the first cell, the second measurement resource originates from the second cell, and the first and second cells are of different types, the threshold is selected based on the type configuration of the second cell.

[0273] Based on the above description, the terminal device needs to measure the second measurement resource to compare its signal quality with that of the first measurement resource. In the first measurement resource, the current serving beam is related to the first reference signal associated with the transmission configuration indication (TCI). In the second measurement resource, the candidate serving beam is explicitly configured by the network device.

[0274] The second measurement resource may contain multiple reference signals, such as multiple reference signals from the same cell or multiple cells. Therefore, the terminal device may need to measure a large number of reference signals, increasing its power consumption. Thus, it is necessary to reduce the number of reference signals in the second measurement resource. Furthermore, due to the mobility of the terminal device, the distance between the serving cell and neighboring cells may change. Therefore, it is necessary to dynamically adjust the reference signals that the terminal device needs to measure.

[0275] Based on this, network devices can employ various implementation methods to instruct terminal devices to determine the reference signal that needs to be measured.

[0276] Below, in conjunction with Figure 3 and Figure 4 It describes in detail the specific process by which the network device instructs the terminal device to determine the reference signal that needs to be measured.

[0277] Please see Figure 3 , Figure 3 This is an interactive flowchart illustrating a communication method provided in an embodiment of this application. Figure 3 As shown, the communication method provided in this application may include:

[0278] S201. The network device sends the first instruction information to the terminal device.

[0279] Accordingly, the terminal device receives the first instruction information sent by the network device.

[0280] The first indication information is used to indicate the third measurement resource. The reference signal in the third measurement resource includes at least one reference signal from the second measurement resource. This application does not limit the transmission method of the first indication information. In some examples, the first indication information may be indicated by a medium access control control element (MAC CE) or downlink control information (DCI). This application does not limit the representation method of the first indication information. In some examples, the first indication information may include the identifier of the reference signal or cell corresponding to the third measurement resource, such as cell index information, reference signal index information, etc.

[0281] In other words, all reference signals in the third measurement resource are included in the second measurement resource, and the number of reference signals in the third measurement resource is less than the number of reference signals in the second measurement resource.

[0282] As can be seen, by using the first indication information, the network device can indicate a third measurement resource with a smaller number of reference signals to the terminal device. This allows the terminal device to reduce the number of reference signals used for measurement.

[0283] Furthermore, the second reference signal is included in the third measurement resource. Therefore, after the terminal device measures the third measurement resource, the measurement result of the reference signal in the third measurement resource includes the second measurement result. Consequently, the terminal device can determine that the trigger condition is met. When the trigger condition is met, the terminal device can execute S202.

[0284] S202. When the triggering conditions are met, the terminal device sends a channel status information report to the network device.

[0285] Accordingly, the network device receives the channel status information report sent by the terminal device.

[0286] Among them, S202 and Figure 2 The implementation of S101 is similar, and will not be described in detail here.

[0287] It is evident that the network device pre-configures X reference signals, i.e., the second measurement resources, for the terminal device at the RRC layer. Furthermore, the network device indicates Y reference signals, i.e., the third measurement resources, to the terminal device. These Y reference signals belong to the X reference signals configured at the RRC layer, meaning Y is less than X. Here, X and Y are positive integers greater than 1.

[0288] In some examples, X reference signals belong to the reference signals of M cells, and Y reference signals belong to the reference signals of N cells. Then, N cells belong to the M cells configured in the RRC layer, meaning M is greater than N, and X and Y are positive integers greater than 1.

[0289] In summary, by providing further instructions through network devices, terminal devices can reduce the measurement of secondary measurement resources and lower the measurement overhead of the terminal devices.

[0290] Please see Figure 4 , Figure 4 This is an interactive flowchart illustrating a communication method provided in an embodiment of this application. Figure 4 As shown, the communication method provided in this application may include:

[0291] S301. The network device sends the second configuration information to the terminal device.

[0292] Correspondingly, the terminal device receives the second configuration information sent by the network device.

[0293] The second configuration information includes the correspondence between the reference signals in the fourth measurement resource and the reference signals in the second measurement resource. Furthermore, the first and second configuration information can be the same or different configuration information. This application does not limit this. Moreover, the reference signals in the fourth measurement resource include at least the first reference signal. That is, the second configuration information includes at least the correspondence between the first reference signal and the candidate reference signal.

[0294] This application does not limit the way the correspondence is represented.

[0295] S302. The terminal device determines the fifth measurement resource from the second measurement resources based on the correspondence and the first reference signal.

[0296] Therefore, the reference signals in the fifth measurement resource include at least one reference signal from the second measurement resource. In other words, all reference signals in the fifth measurement resource are included in the second measurement resource, and the number of reference signals in the fifth measurement resource is less than the number of reference signals in the second measurement resource.

[0297] Furthermore, the second reference signal is included in the fifth measurement resource. Therefore, after the terminal device measures the fifth measurement resource, the measurement result of the reference signal in the fifth measurement resource includes the second measurement result. Consequently, the terminal device can determine that the trigger condition is met. When the trigger condition is met, the terminal device can execute S303.

[0298] S303. When the triggering conditions are met, the terminal device sends a channel status information report to the network device.

[0299] Accordingly, the network device receives the channel status information report sent by the terminal device.

[0300] Among them, S303 and Figure 2 The implementation of S101 is similar, and will not be described in detail here.

[0301] It is evident that the network device includes the correspondence between the fourth measurement resource and the second measurement resource in the information configured for the terminal device. The terminal device can determine the fifth measurement resource from the second measurement resource based on the current first measurement resource.

[0302] In some embodiments, for a reference signal in a fourth measurement resource, the correspondence may indicate that the coverage of the reference signal is adjacent to the coverage of the cell corresponding to the reference signal in the second measurement resource, that is, the cell in the cell corresponding to the reference signal in the second measurement resource that is adjacent to the cell corresponding to the reference signal in the direction of the beam corresponding to the reference signal.

[0303] For example, please see Figure 5 , Figure 5 This is a schematic diagram of a communication method provided in an embodiment of this application.

[0304] like Figure 5 As shown, cell 1 has two reference signals, namely reference signal 1 and reference signal 2. The beams transmitting reference signal 1 and reference signal 2 are different, so the coverage areas of these two beams are different.

[0305] The coverage areas of reference signal 1 are adjacent to those of cells 2 and 3, respectively. In other words, the beam transmitting reference signal 1 is relatively close to the coverage areas of cells 2 and 3. Similarly, the coverage areas of reference signal 2 are adjacent to those of cells 4 and 5, respectively. In other words, the beam transmitting reference signal 2 is relatively close to the coverage areas of cells 4 and 5.

[0306] If the first reference signal is reference signal 1, then the fifth measurement resource may include reference signals associated with cells 2 and 3, or reference signals associated with cells 1, 2, and 3, or reference signals associated with cell 1. In this case, the second measurement resource may be reference signals associated with cells 1, 2, 3, 4, and 5. The fifth measurement resource is a subset of the reference signals of the second measurement resource, and the second reference signal is one of the reference signals in the fifth measurement resource.

[0307] If the first reference signal is reference signal 2, then the fifth measurement resource may include the reference signals associated with cells 4 and 5, or the reference signals associated with cells 1, 4, and 5, or the reference signal associated with cell 1. In this case, the second measurement resource may be the reference signals associated with cells 1, 2, 3, 4, and 5. The fifth measurement resource is a subset of the reference signals of the second measurement resource, and the second reference signal is one of the reference signals in the fifth measurement resource.

[0308] In summary, by using the corresponding relationships configured in the network devices, terminal devices can reduce the measurement of secondary measurement resources and lower the measurement overhead of the terminal devices.

[0309] Figure 3 and Figure 4The methods described herein can be used separately or in combination, and this application does not limit this. When used in combination, the terminal device can measure all reference signals in the third and fifth measurement resources, or it can measure the overlapping reference signals in the third and fifth measurement resources.

[0310] Based on the above description, network devices can also instruct terminal devices on what information to include in the CSI report.

[0311] Below, in conjunction with Figure 6 and Figure 7 It provides a detailed description of the specific information that network devices instruct terminal devices to report.

[0312] Please see Figure 6 , Figure 6 This is an interactive flowchart illustrating a communication method provided in an embodiment of this application. Figure 6 As shown, the communication method provided in this application may include:

[0313] S401. The network device sends a second instruction message to the terminal device.

[0314] Correspondingly, the terminal device receives the second instruction information sent by the network device.

[0315] The second indication information is used to indicate the measurement result of the first reference signal sent by the terminal device. Furthermore, the second indication signal and the first indication information can be the same indication information or different indication information. This application does not limit this.

[0316] S402. When the triggering condition is met, the terminal device sends a channel status information report to the network device according to the second instruction information.

[0317] Accordingly, the network device receives the channel status information report sent by the terminal device.

[0318] The channel state information report is used to indicate the first measurement result and the second measurement result.

[0319] Therefore, the terminal device needs to report the measurement results of the reference signal in the second measurement resource and the measurement results of the reference signal in the first measurement resource in the CSI report.

[0320] In summary, the CSI report transmitted by the terminal device to the network device based on the second indication information carries both the first and second measurement results.

[0321] The second indication information may indicate only the reporting of the first measurement result, or it may indicate the reporting of the first measurement result as well as the measurement results of other reference signals in the first measurement resource besides the first reference signal. Additionally, the second indication may also indicate the number of measurement results for other reference signals.

[0322] This helps network devices compare the signal quality of the current service link and candidate service connections, enabling network devices to perform operations such as resource allocation, scheduling decisions, beam management, and handover control within or between cells, ensuring the communication continuity and quality of terminal devices.

[0323] Please see Figure 7 , Figure 7 This is an interactive flowchart illustrating a communication method provided in an embodiment of this application. Figure 7 As shown, the communication method provided in this application may include:

[0324] S501, The network device sends a third instruction message to the terminal device.

[0325] Correspondingly, the terminal device receives the third instruction information sent by the network device.

[0326] The third indication information is used to instruct the terminal device to send the measurement results of the reference signal of the serving cell in the second measurement resource.

[0327] S502. When the triggering conditions are met, the terminal device sends a channel status information report to the network device according to the third instruction information.

[0328] Accordingly, the network device receives the channel status information report sent by the terminal device.

[0329] The channel state information report is also used to indicate the measurement results of the reference signal of the serving cell in the second measurement resource.

[0330] Therefore, the terminal device needs to report the measurement results of the reference signal in the second measurement resource in the CSI report.

[0331] In summary, the CSI report transmitted by the terminal device to the network device based on the third indication information carries the measurement results of the reference signal of the serving cell in the second measurement resource and the measurement results of the reference signal of the non-serving cell in the second measurement resource.

[0332] This helps network devices determine more of the signal quality of the current serving link, enabling them to identify reference signals with better signal quality within the serving cell, thus ensuring communication continuity and quality for terminal devices.

[0333] Based on the above description, once the terminal device determines that the triggering conditions are met, it can initiate a CSI report. This can lead to frequent CSI report initiations by the terminal device. Therefore, in S101, the terminal device can prevent frequent CSI reports by limiting the number of reports and / or the time limit.

[0334] In some examples, when the second reference signal meets the trigger condition more times than the first time, the terminal device can send a channel state information report to the network device.

[0335] Each reference signal in the second measurement resource can be associated with a counter. The counter starts when the reference signal first meets the trigger condition. Typically, the initial value of the counter is set to a default value, such as 0. The terminal device initiates a CSI report only when the counter value is greater than or equal to the initial count.

[0336] For the second reference signal, a counter can be associated with it. The counter starts when the second reference signal first meets the trigger condition. Each time the second reference signal meets the trigger condition, the counter value increments by 1, until the counter value is greater than or equal to the initial count, at which point the terminal device will initiate a CSI report. This ensures that the trigger condition is met multiple times before occurring, avoiding brief periods of trigger condition fulfillment due to ping-pong switching.

[0337] The first number can be configured by the network device or a predefined value can be used; this application does not limit this.

[0338] For example, taking the second reference signal as reference signal 1, once the signal quality of reference signal 1 is greater than the sum of the signal quality of the first reference signal and the set value, the counter value is incremented by 1. When the counter value is greater than or equal to the first count, the terminal device initiates a CSI report. When the counter value is less than the first count, the counter does not operate, and the terminal device does not initiate a CSI report.

[0339] Therefore, by counting the number of times the triggering condition is met by a reference signal, the terminal device can delay the initiation of a CSI report, avoid frequent CSI reports, and the reliability of the triggering condition can be improved by counting multiple times.

[0340] Specifically, the terminal device can initiate a CSI report when the number of times a reference signal meets the trigger condition is greater than the first count. Alternatively, the terminal device can initiate a CSI report when the number of times multiple reference signals meet the trigger condition is greater than the first count.

[0341] In some examples, when the total number of times the triggering condition is met by the second reference signal and the reference signal belonging to the same cell as the second reference signal is greater than the third time, the terminal device can send a channel state information report to the network device.

[0342] The reference signal in the second measurement resource corresponds to multiple cells, and each cell can be associated with a counter. The counter starts when the reference signal in a cell first meets the trigger condition. Typically, the initial value of the counter is set to a default value, such as 0. The terminal device initiates a CSI report only when the counter value is greater than or equal to the third count.

[0343] For the cell corresponding to the second reference signal, a counter can be associated with that cell. All reference signals in that cell include the second reference signal and other reference signals belonging to the same cell as the second reference signal. The counter starts when any reference signal in that cell first meets the trigger condition. Each time a reference signal in that cell meets the trigger condition, the counter value is incremented by 1, until the counter value is greater than or equal to the second count. Only then will the terminal device initiate a CSI report. This ensures that the trigger condition is met multiple times before it occurs, avoiding transient fulfillment of the trigger condition due to ping-pong handover.

[0344] In this scenario, multiple reference signals in a cell may meet the triggering condition at the same time or at different times. If X reference signals in the cell meet the triggering condition at the same time, the counter value is incremented by X, where X is the number of reference signals that meet the triggering condition at the same time, and X is a positive integer.

[0345] The third number can be configured by the network device or a predefined value; this application does not limit this.

[0346] For example, taking multiple reference signals in a cell, including reference signal 1 and reference signal 2, if the signal quality of reference signal 1 is greater than the sum of the signal quality of the first reference signal and a set value, the counter value is incremented by 1. If the signal quality of reference signal 2 is greater than the sum of the signal quality of the first reference signal and the set value, the counter value is incremented by 1 again, and so on. When the counter value is greater than or equal to the third count, the terminal device initiates a CSI report. When the counter value is less than the third count, the counter does not operate, and the terminal device does not initiate a CSI report.

[0347] Therefore, by counting the total number of times the terminal device meets the triggering condition through the reference signal in a cell, the time of initiating the CSI report can be delayed, the frequent occurrence of CSI reports can be avoided, and multiple counts can also improve the reliability of the triggering condition.

[0348] Specifically, the terminal device can initiate a CSI report when the total number of times the reference signal in a single cell meets the trigger condition exceeds the third count. Alternatively, the terminal device can initiate a CSI report when the total number of times the reference signal in multiple cells meets the trigger condition exceeds the third count.

[0349] In some examples, when the second reference signal meets the trigger condition more times than the second time within the first time window, the terminal device can send a channel state information report to the network device.

[0350] Each reference signal in the second measurement resource can be associated with a counter. The counter starts when the reference signal first meets the trigger condition. Typically, the initial value of the counter is set to a default value, such as 0. The terminal device initiates a CSI report only when the counter value is greater than or equal to the second count within the first time window.

[0351] The first time window can be a fixed duration. It takes effect when the reference signal first meets the trigger condition. Within the first time window, the counter value stops counting when it is greater than or equal to the second count. At the end of the first time window, it stops counting regardless of whether the counter value is greater than or less than the second count. At this point, the terminal device can continue to determine whether the reference signal meets the trigger condition.

[0352] Alternatively, the first time window can also be a sliding window. Using this sliding window, the terminal device initiates a CSI report only when it confirms that the number of times the reference signal meets the trigger condition is greater than or equal to the second count.

[0353] For the second reference signal, a counter can be associated with it. When the second reference signal first meets the trigger condition, the counter starts, and the first time window becomes effective. Each time the second reference signal meets the trigger condition, the counter value increments by 1, until the counter value within the first time window is greater than or equal to the second increment. Only then will the terminal device initiate a CSI report. This ensures that the trigger condition is met multiple times within a time window, avoiding transient fulfillment of the trigger condition due to ping-pong handover.

[0354] The second number can be configured by the network device or a predefined value; this application does not limit this. The first time window can be configured by the network device or a predefined value; this application does not limit this.

[0355] Please see Figure 8 , Figure 8 This is a schematic diagram of a counter provided in an embodiment of this application.

[0356] like Figure 8As shown, taking the second reference signal as reference signal 1 and the initial value of the counter as 0 as an example, in the first occasion, if the signal quality of reference signal 1 is greater than the sum of the signal quality of the first reference signal and the set value, the counter value is incremented by 1, and the first time window takes effect. In the second occasion, if the signal quality of reference signal 1 is greater than the sum of the signal quality of the first reference signal and the set value, the counter value is incremented by 1 again, and so on. Within the first time window, if the counter value is greater than or equal to the second count, the terminal device initiates a CSI report. After the first time window, if the counter value is less than the second count, the counter is reset to zero, and the terminal device does not initiate a CSI report.

[0357] Therefore, by using a reference signal to determine the number of times the trigger condition is met and the time window for that number of times, the terminal device can delay the initiation of a CSI report, thus avoiding frequent CSI reports. Multiple counts can also improve the reliability of the trigger condition.

[0358] Specifically, the terminal device can initiate a CSI report when the number of times a reference signal meets the trigger condition exceeds the second number within the first time window. Alternatively, the terminal device can initiate a CSI report when the number of times multiple reference signals meet the trigger condition exceeds the second number within the first time window.

[0359] In some examples, when the total number of times the second reference signal and the reference signal belonging to the same cell as the second reference signal meet the triggering condition within the second time window is greater than the fourth time, the terminal device can send a channel state information report to the network device.

[0360] The reference signal in the second measurement resource corresponds to multiple cells, and each cell can be associated with a counter. The counter starts when the reference signal in a cell first meets the trigger condition, and the second time window becomes effective. Typically, the initial value of the counter is set to a default value, such as 0. The terminal device initiates a CSI report only when the counter value is greater than or equal to the fourth occurrence within the second time window.

[0361] The second time window can be a fixed duration. It takes effect when the reference signal in the cell first meets the trigger condition. Within the second time window, the second time window stops counting when the counter value is greater than or equal to the fourth count. At the end of the second time window, it stops counting regardless of whether the counter value is still greater than or equal to the fourth count. At this point, the terminal device can continue to determine whether the reference signal in the cell meets the trigger condition.

[0362] Alternatively, the second time window can also be a sliding window. Using this sliding window, the terminal device initiates a CSI report only when it confirms that the number of times the reference signal in the cell meets the triggering condition is greater than or equal to the fourth message.

[0363] For the cell corresponding to the second reference signal, a counter can be associated with that cell. All reference signals in that cell include the second reference signal and other reference signals belonging to the same cell as the second reference signal. When any reference signal in that cell first meets the trigger condition, the counter starts, and the second time window becomes effective. Each time a reference signal in that cell meets the trigger condition, the counter value increments by 1, until the counter value within the second time window is greater than or equal to the fourth time. Only then will the terminal device initiate a CSI report. This ensures that the trigger condition occurs only after multiple fulfillments within a time window, avoiding transient fulfillment of the trigger condition due to ping-pong handover.

[0364] In this scenario, multiple reference signals in the cell may meet the trigger condition simultaneously, or they may meet the trigger condition at different times. If X reference signals in the cell meet the trigger condition simultaneously, the counter value is incremented by X, where X is the number of reference signals that meet the trigger condition at the same time, and X is a positive integer.

[0365] For example, taking multiple reference signals in a cell, including Reference Signal 1 and Reference Signal 2, as an example, in the first occasion, if the signal quality of Reference Signal 1 is greater than the sum of the signal quality of the first reference signal and a set value, the counter value is incremented by 1. In the second occasion, if the signal quality of Reference Signal 1 is greater than the sum of the signal quality of the first reference signal and the set value, the counter value is incremented by 1 again. In the second occasion, if the signal quality of Reference Signal 2 is also greater than the sum of the signal quality of the first reference signal and the set value, the counter value is incremented by 1 again. In the third occasion, if the signal quality of Reference Signal 2 is greater than the sum of the signal quality of the first reference signal and the set value, the counter value continues to increment by 1, and so on. Within the second time window, if the counter value is greater than or equal to the fourth count, the terminal device initiates a CSI report. After the second time window, if the counter value is less than the fourth count, the counter is reset to zero, and the terminal device does not initiate a CSI report.

[0366] Therefore, by using the total number of times the triggering condition is met by the reference signal in a cell and the time window of the total number of times, the terminal device can delay the time of initiating a CSI report, avoid the frequent occurrence of CSI reports, and the multiple counts can also improve the reliability of the triggering condition.

[0367] Specifically, the terminal device can initiate a CSI report when the total number of times the reference signal in one cell meets the trigger condition exceeds the fourth number within the second time window. Alternatively, the terminal device can initiate a CSI report when the total number of times the reference signal in multiple cells meets the trigger condition exceeds the fourth number within the second time window.

[0368] In summary, this can prevent terminal devices from frequently initiating CSI reports due to movement.

[0369] Based on the above description, if the measurement result of a reference signal in the CSI report is expressed as an absolute measurement value, then the reference signal must meet the triggering condition. If the measurement result of a reference signal is expressed as a differential measurement value, then whether the reference signal meets the triggering condition is not limited.

[0370] Among them, the priority ranking of the reference signal corresponding to the measurement result expressed in absolute measurement value is higher than the priority ranking of the reference signal corresponding to the measurement result expressed in differential measurement value.

[0371] When the measurement result of a reference signal meets the triggering condition, the CSI report may include at least the identifier of the reference signal and the measurement result, which is expressed as an absolute measurement value.

[0372] When the measurement results of multiple reference signals meet the triggering conditions, the terminal device can typically select the best-performing reference signal from among them. The CSI report can at least include the identifier of the best-performing reference signal and its measurement result, which is expressed as an absolute measurement value.

[0373] For example, the best performing reference signal could be the one with the highest RSRP or the one with the highest SINR.

[0374] In addition, the CSI report may also include the identification and measurement results of other reference signals. The measurement results of other reference signals are expressed using differential measurements. Other reference signals may or may not meet the trigger conditions, and may include both reference signals that meet and do not meet the trigger conditions; this application does not limit this. The terminal device can set the number of other reference signals in the CSI report according to actual needs and its own circumstances.

[0375] In some instances, CSI reports, based on the number of reference signals, can include various representations.

[0376] As a feasible representation, a CSI report may include an identifier and measurement result of a reference signal. This reference signal must meet the triggering conditions. The measurement result of the reference signal can be expressed as an absolute measurement value.

[0377] As another feasible representation, the CSI report can include the identification and measurement results of multiple reference signals. Since the measurement results of multiple reference signals represent the measurement results of reference signals from multiple cells, the identification and measurement results of reference signals from cells that meet the triggering conditions have a higher priority than those from cells that do not meet the triggering conditions.

[0378] The reference signals for cells that meet the triggering conditions can be one or more. The reference signals for cells that do not meet the triggering conditions can also be one or more. The measurement results of the reference signals for cells that do not meet the triggering conditions can be represented by differential measurements.

[0379] When there is only one reference signal for a cell that meets the triggering conditions, the corresponding measurement result can be represented by an absolute measurement value.

[0380] When multiple reference signals exist for a cell that meets the triggering conditions, the measurement result of the reference signal with the best performance is ranked higher than the ranking priority of other measurement results among the multiple corresponding measurement results. In some examples, the CSI report is based on the type of reference signal and may include multiple representation methods.

[0381] As a feasible representation, the channel state information report may include at least the identifier of the second measurement result and the second reference signal corresponding to the second measurement result.

[0382] The identifier of the reference signal is used to uniquely identify the reference signal. For example, the identifier of the reference signal can be the index information of the reference signal.

[0383] In some embodiments, the identifier of the second reference signal corresponding to the second measurement result has a higher priority than the arrangement priority of the second measurement result. When there is only one second measurement result, the second measurement result can be represented by an absolute measurement value.

[0384] When there are multiple second measurement results, the reference signal with the best performance among the multiple second measurement results can be represented by absolute measurement values, while the other second measurement results can be represented by differential measurement values.

[0385] Additionally, terminal devices can configure the number of second measurement results in the CSI report based on actual needs and their own circumstances. Alternatively, the number of measurement results to be reported within a cell can be indicated by the network device.

[0386] Therefore, when the channel state information report includes multiple measurement results, these multiple measurement results are the measurement results of reference signals from multiple cells in the second measurement resource. The multiple measurement results include the second measurement result and the remaining measurement results.

[0387] The remaining measurement results are the measurement results of reference signals in the second measurement resource other than the second reference signal. The reference signals corresponding to the remaining measurement results may or may not meet the trigger conditions, and may include reference signals that meet and do not meet the trigger conditions.

[0388] When the second measurement result is the measurement result of the reference signal with the best performance, the second measurement result is represented by an absolute measurement value, and the remaining measurement results are represented by differential measurement values. The differential measurement value is the difference between the measurement result of the reference signal corresponding to the remaining measurement result and the second measurement result. The remaining measurement results may include the measurement result of the reference signal belonging to the same cell as the second reference signal.

[0389] Therefore, the ranking priority of the second measurement result is higher than the ranking priority of the measurement results of the reference signal belonging to the same cell as the second reference signal.

[0390] The remaining measurement results may include: the measurement results of the reference signal belonging to the same cell as the second reference signal and the measurement results of the reference signals of other cells that do not belong to the same cell as the second reference signal.

[0391] Therefore, the ranking priority of the second measurement result is higher than that of the measurement result of the reference signal belonging to the same cell as the second reference signal, and the ranking priority of the measurement result of the reference signal belonging to the same cell as the second reference signal is higher than that of the measurement result of the reference signal from other cells.

[0392] In the CSI report, the second measurement result is the highest priority measurement result, expressed as an absolute value. Other measurement results of reference signals belonging to the same cell as the second reference signal are expressed as differential values. In this case, the network device can instruct the terminal device to only report the measurement results of reference signals belonging to the same cell as the second reference signal or the measurement results of reference signals from cells that meet the triggering conditions. Therefore, the CSI report can be in the format shown in Table 1.

[0393] Table 1. Format of CSI Reports

[0394] Index information of the first reference signal of the i-th cell Index information of the second reference signal of the i-th cell Index information of the third reference signal of the i-th cell Index information of the fourth reference signal of the i-th cell Absolute measurement value of RSRP of the first reference signal of the i-th cell Differential measurement value of RSRP of the second reference signal of the i-th cell Differential measurement value of RSRP of the third reference signal of the i-th cell Differential measurement value of RSRP of the fourth reference signal of the i-th cell

[0395] In the CSI report, the second measurement result is the highest priority measurement result. The second measurement result is represented as an absolute measurement value. Other measurement results of the reference signal belonging to the same cell as the second reference signal are represented as differential measurement values. Measurement results of reference signals from other cells not belonging to the second reference signal are also represented as differential measurement values. In this case, the network device can instruct the terminal device to report the measurement results of K cells. These K cells include the measurement results of the reference signal from the cell containing the second reference signal (or the measurement results of the reference signal from the cell triggering the condition) and the measurement results of the reference signals from K-1 other cells not belonging to the second reference signal. K is a positive integer greater than 1.

[0396] For example, suppose that the four reference signals of cell i meet the triggering conditions, while the four reference signals of cell j do not meet the triggering conditions. The reference signal identification is illustrated using the reference signal index information, and the reference signal measurement results are illustrated using the reference signal RSRP. Then, the CSI report can be in the format shown in Table 2.

[0397] Table 2: Format of CSI Reports

[0398]

[0399]

[0400] It can be seen that, in the second measurement resource, the first reference signal, the second reference signal, the third reference signal, and the fourth reference signal of the i-th cell are the top four reference signals in terms of performance in the i-th cell.

[0401] Among them, the first reference signal of cell i has the best performance compared to the other three reference signals besides the first reference signal. That is, the RSRP of the first reference signal of cell i is the largest.

[0402] In the second measurement resource, the first reference signal, the second reference signal, the third reference signal, and the fourth reference signal of the j-th cell are the top four reference signals in terms of performance among all cells except the i-th cell.

[0403] In summary, a CSI report should include at least the identification and measurement results of a reference signal in the second measurement resource that meets the triggering conditions.

[0404] As another feasible representation, in addition to including the identifier of the second reference signal corresponding to the second measurement result, the channel state information report may also include: the first measurement result.

[0405] The second measurement result has a higher priority than the first measurement result. In other words, the first measurement result has the lowest priority compared to the second. Typically, the first measurement result is represented using differential measurements.

[0406] Additionally, the CSI report may or may not include the identifier of the first reference signal corresponding to the first measurement result. Since the beam transmitting the first reference signal is the currently serving beam, the network device already knows which beams(s) are the currently serving beams. Therefore, the CSI report does not need to additionally indicate the identifier of the first reference signal corresponding to the first measurement result.

[0407] When the channel state information report includes multiple measurement results, the multiple measurement results include a first measurement result and remaining measurement results. The remaining measurement results are the measurement results of reference signals in the first measurement resource other than the first reference signal.

[0408] The remaining measurement results may include: the measurement results of the reference signal belonging to the same cell as the first reference signal and the measurement results of the reference signals of other cells that do not belong to the same cell as the first reference signal.

[0409] Therefore, the ranking priority of the first measurement result is higher than that of the measurement results of other reference signals belonging to the same cell as the first reference signal, and the ranking priority of the measurement results of the reference signals belonging to the same cell as the first reference signal is lower than that of the measurement results of reference signals from other cells.

[0410] In the CSI report, the first measurement result is the first measurement result, which is represented by differential measurement values. The measurement results of the reference signal belonging to the same cell as the first reference signal are represented by differential measurement values, and the measurement results of the reference signals of other cells not belonging to the same cell as the first reference signal are represented by differential measurement values.

[0411] For example, suppose that at least one reference signal in cell i satisfies the triggering condition, four reference signals in cell j do not satisfy the triggering condition, and the four reference signals in cell k are the reference signals of the cell where the first measurement resource is located. The identification of the reference signals is illustrated using the index information of the reference signals, and the measurement results of the reference signals are illustrated using the RSRP of the reference signals. Then, the CSI report can be in the form shown in Table 3.

[0412] Table 3: Format of CSI Reports

[0413] Index information of the first reference signal of the i-th cell Index information of the second reference signal of the i-th cell Index information of the third reference signal of the i-th cell Index information of the fourth reference signal of the i-th cell Index information of the first reference signal of the j-th cell Index information of the second reference signal of the j-th cell Index information of the third reference signal of the j-th cell Index information of the fourth reference signal of the j-th cell Index information of the first reference signal of the k-th cell Index information of the second reference signal of the k-th cell Index information of the third reference signal of the k-th cell Index information of the fourth reference signal of the k-th cell Absolute measurement value of RSRP of the first reference signal of the i-th cell Differential measurement value of RSRP of the second reference signal of the i-th cell Differential measurement value of RSRP of the third reference signal of the i-th cell Differential measurement value of RSRP of the fourth reference signal of the i-th cell Differential measurement value of RSRP of the first reference signal of the j-th cell Differential measurement value of RSRP of the second reference signal of the j-th cell Differential measurement value of RSRP of the third reference signal of the j-th cell Differential measurement value of RSRP of the fourth reference signal of the j-th cell Differential measurement value of RSRP of the first reference signal of the k-th cell Differential measurement value of RSRP of the second reference signal of the k-th cell Differential measurement value of RSRP of the third reference signal of the k-th cell Differential measurement value of RSRP of the fourth reference signal of the k-th cell

[0414] It can be seen that, in the second measurement resource, the first reference signal, the second reference signal, the third reference signal, and the fourth reference signal of the i-th cell are the top four reference signals in terms of performance in the i-th cell.

[0415] Among them, the first reference signal of cell i has the best performance compared to the other three reference signals besides the first reference signal. That is, the RSRP of the first reference signal of cell i is the largest.

[0416] In the second measurement resource, the first reference signal, the second reference signal, the third reference signal, and the fourth reference signal of the j-th cell are the top four reference signals in terms of performance among all cells except the i-th cell.

[0417] In the first measurement resource, the first reference signal of the kth cell is the first reference signal, and the second reference signal, the third reference signal, and the fourth reference signal of the kth cell are three reference signals belonging to the same cell as the first reference signal.

[0418] In summary, a CSI report includes at least the identifier and measurement result of a reference signal in the second measurement resource that meets the triggering condition, and may also include the measurement result of a reference signal in the first measurement resource that serves as a benchmark for determining whether the triggering condition has been met.

[0419] Based on the above description, in a CSI report, the second measurement result typically uses more bits for quantization, while the remaining measurements typically use fewer bits. Therefore, the second measurement result is more accurate. After being encoded using methods such as polar codes, information with higher priority in the CSI report is more reliable. Correspondingly, network devices need to decode higher-priority information with a higher bit error rate.

[0420] In summary, the terminal device can measure the reference signal in the second measurement resource. However, the terminal device can select which measurement results to report and initiate a CSI report based on its actual needs. The CSI report must include at least the identifier of the second measurement result and the corresponding second reference signal. Furthermore, depending on actual needs, the CSI report may also include the first measurement result.

[0421] In CSI reports, the measurement results of reference signals for cells that meet the triggering conditions are given higher priority.

[0422] In a CSI report, the first measurement result is presented as an absolute value, while the remaining measurements are presented as differential values. Differential values ​​can also be referred to as relative values.

[0423] In the CSI report, the measurement results of the reference signals of the cells in the first measurement resource have the lowest priority compared to the second measurement resource.

[0424] By way of example, this application also provides a communication method.

[0425] Please see Figure 9 , Figure 9 This is an interactive flowchart illustrating a communication method provided in an embodiment of this application. The method is applied to a terminal device and a network device, wherein the communication device can be... Figure 1 The communication equipment or devices in the communication equipment, network equipment can be Figure 1 The network device or device within the network device. For simplicity, let's take the example where the method is executed by a terminal device and a network device, such as... Figure 9 As shown, the communication method provided in this application may include:

[0426] S601, The terminal device sends a channel status information report to the network device.

[0427] The channel state information report includes a second measurement result for the second reference signal and a third measurement result for the third reference signal. The second measurement result has a higher sorting priority than the third measurement result.

[0428] The second reference signal meets the triggering condition, while the third reference signal does not. The triggering conditions are described above and will not be repeated here.

[0429] When a CSI report is required, the terminal device can include both a second and a third measurement result in the report, with the second measurement result having a higher priority than the third. The terminal device can encode the CSI report using various methods, such as polar codes. After encoding, for each measurement result in the CSI report, the higher its priority, the higher its reliability. Thus, the reliability of the second measurement result is higher than that of the third. Consequently, the terminal device can send the CSI report to the network device, allowing the network device to prioritize understanding the signal quality of the second reference signal.

[0430] The communication method provided in this application allows a terminal device to carry in its CSI report both the second measurement result of the reference signal that meets the triggering conditions and the measurement result of the reference signal that does not meet the triggering conditions. The measurement results of the reference signal that meets the triggering conditions have a higher priority than those of the reference signal that does not meet the triggering conditions, thus improving the reliability of the measurement results of the reference signal that meets the triggering conditions. Consequently, the terminal device can send a CSI report to the network device, enabling the network device to prioritize the signal quality of the reference signals that meet the triggering conditions. This helps the network device compare the signal quality of the current serving link and candidate serving connections, allowing the network device to perform resource allocation, scheduling decisions, beam management, and handover control within or between cells, ensuring the communication continuity and quality of the terminal device.

[0431] Figure 2 and Figure 9 The difference between the methods shown is: Figure 2 In this context, the focus is on the configuration and triggering of CSI reports. Terminal devices only initiate CSI reports when triggering conditions are met. Figure 9 The focus is on the content and format of the CSI report. The CSI report includes: second measurement results of the reference signal that meets the triggering conditions, and measurement results of the reference signal that does not meet the triggering conditions, with the measurement results of the reference signal that meets the triggering conditions having a higher sorting priority than the measurement results of the reference signal that does not meet the triggering conditions.

[0432] Based on the above description, measurement results in CSI reports can be presented in various ways.

[0433] In some instances, both the second and third measurement results are represented using absolute values. This method of representing results as absolute values ​​allows network devices to directly obtain the measurement results.

[0434] In some instances, the second measurement result is represented using an absolute measurement value, while the third measurement result is represented using a differential measurement value, where the differential measurement value is the difference between the third and second measurement results. Therefore, using both absolute and differential measurement values ​​allows for higher accuracy in the second measurement result and also reduces overhead.

[0435] In some embodiments, the number of bits in the absolute measurement is greater than the number of bits in the differential measurement. For example, if the absolute measurement is 5 bits, the differential measurement is 4 bits. The 5-bit absolute measurement is more accurate than the 4-bit differential measurement.

[0436] Based on the above description, in the CSI report, the measurement results of the reference signal belonging to the same cell as the second reference signal are ranked with higher priority than the measurement results of the reference signal from a cell that is different from the cell where the second reference signal is located.

[0437] In this way, the reliability of the reference signal in the cell where the second reference signal is located is higher, enabling network devices to fully understand the signal quality of the second reference signal and the channel status of the cell where the second reference signal is located.

[0438] The cell corresponding to the second reference signal may include one or more cells. The cell corresponding to the third reference signal may also include one or more cells. Thus, four scenarios can be constructed.

[0439] Next, we will explain in detail the ordering of measurement results in the CSI report under four different scenarios.

[0440] When the cell corresponding to the second reference signal is a cell, such as cell 1, and the cell corresponding to the third reference signal is a cell, such as cell 2, the sorting priority of the measurement results of the reference signal in cell 1 is higher than the sorting priority of the measurement results of the reference signal in cell 2.

[0441] For reference signals in cell 1, the ranking priority of the measurement results of reference signals that meet the triggering conditions is higher than the ranking priority of the measurement results of reference signals that do not meet the triggering conditions.

[0442] For reference signals in cell 2, the ranking priority of the measurement results of reference signals that meet the triggering conditions is higher than that of the measurement results of reference signals that do not meet the triggering conditions.

[0443] When the cell corresponding to the second reference signal is a single cell, such as cell 1, and the cell corresponding to the third reference signal includes multiple cells, such as cell 2 and cell 3, the ranking priority of the measurement results of the reference signal in cell 1 is higher than the ranking priority of the measurement results of the reference signals in cell 2 and cell 3.

[0444] For reference signals in cell 1, the ranking priority of the measurement results of reference signals that meet the triggering conditions is higher than the ranking priority of the measurement results of reference signals that do not meet the triggering conditions.

[0445] For reference signals in cell 2, the ranking priority of the measurement results of reference signals that meet the triggering conditions is higher than that of the measurement results of reference signals that do not meet the triggering conditions.

[0446] For reference signals in cell 3, the ranking priority of the measurement results of reference signals that meet the triggering conditions is higher than that of the measurement results of reference signals that do not meet the triggering conditions.

[0447] For reference signals in cell 2 and cell 3, if the best measurement result of the reference signal in cell 2 is better than the best measurement result of the reference signal in cell 3, then the ranking priority of the measurement result of the reference signal in cell 2 is higher than the ranking priority of the measurement result of the reference signal in cell 3. Conversely, the ranking priority of the measurement result of the reference signal in cell 3 is higher than the ranking priority of the measurement result of the reference signal in cell 2.

[0448] When the cell corresponding to the second reference signal includes multiple cells, such as cell 1 and cell 2, and the cell corresponding to the third reference signal is a single cell, such as cell 3, the ranking priority of the measurement results of the reference signals in cell 1 and cell 2 is higher than the ranking priority of the measurement results of the reference signals in cell 3.

[0449] For reference signals in cell 1, the ranking priority of the measurement results of reference signals that meet the triggering conditions is higher than the ranking priority of the measurement results of reference signals that do not meet the triggering conditions.

[0450] For reference signals in cell 2, the ranking priority of the measurement results of reference signals that meet the triggering conditions is higher than that of the measurement results of reference signals that do not meet the triggering conditions.

[0451] For reference signals in cell 1 and cell 2, if the best measurement result of the reference signal in cell 1 is better than the best measurement result of the reference signal in cell 2, then the ranking priority of the measurement result of the reference signal in cell 1 is higher than the ranking priority of the measurement result of the reference signal in cell 2. Conversely, the ranking priority of the measurement result of the reference signal in cell 2 is higher than the ranking priority of the measurement result of the reference signal in cell 1.

[0452] For reference signals in cell 3, the ranking priority of the measurement results of reference signals that meet the triggering conditions is higher than that of the measurement results of reference signals that do not meet the triggering conditions.

[0453] When the cell corresponding to the second reference signal includes multiple cells, such as cell 1 and cell 2, and the cell corresponding to the third reference signal includes multiple cells, such as cell 3 and cell 4, then the ranking priority of the measurement results of the reference signals in cell 1 and cell 2 is higher than the ranking priority of the measurement results of the reference signals in cell 3, and the ranking priority of the measurement results of the reference signals in cell 1 and cell 2 is higher than the ranking priority of the measurement results of the reference signals in cell 4.

[0454] For reference signals in cell 1, the ranking priority of the measurement results of reference signals that meet the triggering conditions is higher than the ranking priority of the measurement results of reference signals that do not meet the triggering conditions.

[0455] For reference signals in cell 2, the ranking priority of the measurement results of reference signals that meet the triggering conditions is higher than that of the measurement results of reference signals that do not meet the triggering conditions.

[0456] For reference signals in cell 1 and cell 2, if the best measurement result of the reference signal in cell 1 is better than the best measurement result of the reference signal in cell 2, then the ranking priority of the measurement result of the reference signal in cell 1 is higher than the ranking priority of the measurement result of the reference signal in cell 2. Conversely, the ranking priority of the measurement result of the reference signal in cell 2 is higher than the ranking priority of the measurement result of the reference signal in cell 1.

[0457] For reference signals in cell 3, the ranking priority of the measurement results of reference signals that meet the triggering conditions is higher than that of the measurement results of reference signals that do not meet the triggering conditions.

[0458] For reference signals in cell 4, the ranking priority of the measurement results of reference signals that meet the triggering conditions is higher than that of the measurement results of reference signals that do not meet the triggering conditions.

[0459] For reference signals in cells 3 and 4, if the best measurement result of the reference signal in cell 3 is better than the best measurement result of the reference signal in cell 4, then the ranking priority of the measurement result of the reference signal in cell 3 is higher than the ranking priority of the measurement result of the reference signal in cell 4. Conversely, the ranking priority of the measurement result of the reference signal in cell 4 is higher than the ranking priority of the measurement result of the reference signal in cell 5.

[0460] In the four scenarios described above, there may be multiple measurement results of the reference signal that meet the triggering conditions. The ordering priority of these multiple measurement results can be set according to the performance of the reference signal corresponding to the measurement result from best to worst, that is, the measurement result of the reference signal with the best performance has the highest ordering priority.

[0461] There may be multiple measurement results of reference signals that do not meet the triggering conditions. The sorting priority of these multiple measurement results can refer to the sorting priority setting method of the measurement results of reference signals that meet the triggering conditions, which will not be elaborated here.

[0462] Based on the above description, the CSI report may also include: the identifier of the second reference signal and the identifier of the third reference signal.

[0463] The identifier of the second reference signal is used to uniquely identify the second reference signal. The identifier of the third reference signal is used to uniquely identify the third reference signal. The identifier of the reference signal can be represented by methods such as the index information of the second reference signal or the index information of the cell in which the second reference signal is located.

[0464] This enables network devices to determine the second and third reference signals in a timely manner.

[0465] Based on the above description, the CSI report may also include: the first measurement result of the first reference signal.

[0466] The second measurement result has a higher sorting priority than the first measurement result. The trigger condition is that the first measurement result is greater than the second measurement result.

[0467] This allows network devices to know the signal quality of the second reference signal and the first reference signal, which helps network devices compare the signal quality of the current service link and the candidate service connection. This enables network devices to perform resource allocation, scheduling decisions, beam management, handover control and other operations within or between cells, ensuring the communication continuity and quality of terminal devices.

[0468] Furthermore, since the beam transmitting the first reference signal is the currently serving beam, the network device already knows which beams(s) are the currently serving beams. Therefore, the CSI report does not need to additionally indicate the identifier of the first reference signal corresponding to the first measurement result, thus reducing overhead. Of course, the CSI report can also include the identifier of the first reference signal.

[0469] In some instances, the first measurement result has the lowest sorting priority. Of course, the first measurement result can also have a higher sorting priority than the third measurement result. This ensures that the second measurement result has the highest sorting priority, thus maximizing its reliability.

[0470] In some instances, the first measurement result is represented as a differential measurement, which is the difference between the first and second measurement results. This reduces overhead.

[0471] In addition, the specific implementation of CSI reports can be found in the descriptions above, such as Tables 2 and 3, which will not be repeated here.

[0472] By way of example, this application also provides a communication device.

[0473] Please see Figure 10 , Figure 10 This is a schematic diagram of the structure of a communication device provided in an embodiment of this application.

[0474] like Figure 10 As shown, the communication device 100 can exist independently or be integrated into other devices. It can communicate with the terminal devices mentioned above to implement the operation corresponding to the network device in any of the above method embodiments.

[0475] The communication device 100 may include a transceiver unit 101. The communication device 100 may also include a processing unit. The transceiver unit 101 can implement corresponding communication functions, and the processing unit is used for data processing.

[0478] Optionally, the transceiver unit 101 may include a sending unit and a receiving unit. The sending unit is used to perform the sending operation in the above method embodiments. The receiving unit is used to perform the receiving operation in the above method embodiments.

[0479] It should be noted that the communication device 100 may include a transmitting unit but not a receiving unit. Alternatively, the communication device 100 may include a receiving unit but not a transmitting unit. Specifically, it depends on whether the above-described scheme executed by the communication device 100 includes both transmitting and receiving actions.

[0480] As an example, the communication device 100 is used to perform the foregoing. Figures 1-8 The actions performed by the terminal device in the illustrated embodiment.

[0481] The communication device 100 may include a transceiver unit 101.

[0482] The transceiver unit 101 is used to send a channel state information report to the network device when the triggering condition is met;

[0483] The triggering conditions include the second measurement result being better than the first measurement result;

[0484] The first measurement result is used to indicate the measurement result of the first reference signal, and the second measurement result is used to indicate the measurement result of the second reference signal. The first reference signal is included in the first measurement resource, and the second reference signal is included in the second measurement resource.

[0485] The reference signal in the first measurement resource corresponds to the serving cell;

[0486] The reference signal in the second measurement resource corresponds to a serving cell and / or a non-serving cell;

[0487] The channel state information report is used at least to indicate the second measurement result.

[0488] In some embodiments, the transceiver unit is further configured to receive first configuration information sent by the network device;

[0489] The first configuration information is used to indicate the transmission power information of the reference signal transmitted by the network device in the second measurement resource and the transmission power information of the reference signal transmitted by the network device in the first measurement resource.

[0490] In some embodiments, the transceiver unit is further configured to receive first indication information sent by the network device;

[0491] The first indication information is used to indicate the third measurement resource; the reference signal in the third measurement resource includes at least one reference signal in the second measurement resource;

[0492] The second reference signal is included in the third measurement resource.

[0493] In some embodiments, the transceiver unit is further configured to receive second configuration information sent by the network device; the second configuration information includes a correspondence between a reference signal in the fourth measurement resource and a reference signal in the second measurement resource; the reference signal in the fourth measurement resource includes at least a first reference signal;

[0494] Based on the correspondence and the first reference signal, a fifth measurement resource is determined from the second measurement resource; the reference signal in the fifth measurement resource includes at least one reference signal from the second measurement resource.

[0495] The second reference signal is included in the fifth measurement resource.

[0496] In some embodiments, the transceiver unit is further configured to receive second indication information sent by the network device; the second indication information is used to instruct the terminal device to send the measurement result of the first reference signal;

[0497] Sending a channel status information report to a network device includes: sending a channel status information report to the network device according to a second indication, wherein the channel status information report is used to indicate a first measurement result and a second measurement result.

[0498] In some embodiments, the transceiver unit is further configured to receive third indication information sent by the network device; the third indication information is used to instruct the terminal device to send the measurement result of the reference signal of the serving cell in the second measurement resource;

[0499] Sending a channel state information report to a network device includes: sending a channel state information report to a network device based on third indication information, wherein the channel state information report is also used to indicate the measurement results of the reference signal of the serving cell in the second measurement resource.

[0500] In some embodiments, the transceiver unit is specifically used to send a channel state information report to the network device when the number of times the second reference signal satisfies the triggering condition is greater than the first number.
