Description

Communication methods, devices and computer-readable storage media

[0001] This application claims priority to Chinese Patent Application No. 202411219187.4, filed on August 30, 2024, entitled "Communication Method, Apparatus and Computer-Readable Storage Medium", the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of communication technology, and in particular to a communication method, apparatus and computer-readable storage medium. Background Technology

[0003] Beamforming is a signal processing technique based on antenna arrays that can concentrate signal energy in a certain direction for transmission, thereby effectively improving coverage, reducing interference to the surrounding environment, and improving communication performance.

[0004] In a wireless communication system, network devices can send measurement configurations to user equipment (UEs), which can then perform measurements based on these configurations. During measurement, UEs can measure different beams and report the beam measurement results to the network device. This allows the network device to perform mobility decisions, beam management, and other functions based on the beam measurement results. Summary of the Invention

[0005] This application discloses a communication method, apparatus, and computer-readable storage medium, which can reduce measurement reporting overhead and save air interface resources.

[0006] The first aspect discloses a communication method that can be applied to a user equipment, a component within the user equipment (e.g., a processor, chip, chip system, circuit, or functional module), or a logic module or software capable of implementing all or part of the user equipment's functions. The following description, using an application to a user equipment as an example, includes: performing measurements based on a measurement configuration to obtain N measurement results, where N is a positive integer; if the N measurement results differ from the previous K measurement results, sending first indication information, where the first indication information indicates the number M of measurement results that differ from the previous K measurement results, where K is a positive integer and M is an integer greater than 0 and less than or equal to N; sending a first measurement report, which includes the M measurement results that differ from the previous K measurement results; or, if the N measurement results are the same as the previous K measurement results, sending second indication information, where the second indication information indicates that the N measurement results are the same as the previous K measurement results.

[0007] In this embodiment, the network device and the user equipment can store the measurement results reported by the user equipment. Therefore, for non-first-time measurement reports, the user equipment can compare the N measurement results obtained in this measurement with the K measurement results previously reported. If the N measurement results obtained in this measurement are the same as the K measurement results previously reported, the user equipment can send a second indication to the network device, and does not need to send the N measurement results obtained in this measurement to the network device. The network device can retrieve the N measurement results from the stored K measurement results previously reported by the user equipment based on the second indication. If the N measurement results obtained in this measurement are different from the K measurement results previously reported, the user equipment can send a first indication to the network device, as well as M measurement results that are different from the K measurement results. If M is not equal to N, the user equipment does not need to send the complete N measurement results obtained in this measurement to the network device. For the (NM) measurement results that are the same as the K measurement results, the network device can retrieve them from the currently stored measurement results. As can be seen, in the above method, for the case where M is not equal to N, the amount of data sent by the user equipment to the network equipment can be reduced, unnecessary signaling overhead can be omitted, thereby saving air interface resources.

[0008] In conjunction with the first aspect, in one possible implementation, the K measurement results correspond to K identifiers, where K equals N; the first measurement report also includes M identifiers corresponding to the different M measurement results, the M identifiers being used to indicate the M measurement results that differ from the K measurement results among the N measurement results.

[0009] In this embodiment of the application, the K measurement results stored by the network device can each correspond to K identifiers. When K equals N, the user equipment can send the M identifiers corresponding to the different M measurement results to the network device. In this way, the network device can accurately obtain the same (NM) measurement results from the stored K measurement results based on the M identifiers.

[0010] In conjunction with the first aspect, in one possible implementation, the method further includes: receiving a first resource indication for indicating a first resource corresponding to the different M measurement results; the sending of the first measurement report includes: sending the first measurement report through the first resource.

[0011] In this embodiment of the application, the network device can dynamically allocate corresponding resources to the user equipment based on the number of measurement results that the user equipment needs to send, which can avoid allocating too many or too few resources and avoid wasting resources.

[0012] In conjunction with the first aspect, in one possible implementation, the first indication information is further used to indicate the activation of a second resource, which corresponds to the different M measurement results; the sending of the first measurement report includes sending the first measurement report through the second resource.

[0013] In this embodiment, the user equipment can activate corresponding resources based on the first indication information, and the network device can determine the resources activated by the user equipment based on the first indication information, thereby receiving the first measurement report through the resources activated by the user equipment. This approach avoids activating too many resources and prevents resource waste.

[0014] In conjunction with the first aspect, in one possible implementation, the first indication information and / or the second indication information are carried in an uplink control message UCI or a media access control-control element MAC CE.

[0015] The second aspect discloses a communication method that can be applied to network devices, components within network devices (e.g., processors, chips, chip systems, circuits, or functional modules), and logic modules or software capable of implementing all or part of the functions of a network device. The following description uses an application to a network device as an example. The communication method may include: receiving first indication information or second indication information; the first indication information indicating the number M of N measurement results that differ from the previous K measurement results, where K and N are positive integers, and M is an integer greater than 0 and less than or equal to N; the second indication information indicating that the N measurement results are the same as the K measurement results; and, upon receiving the first indication information, the method further includes: receiving a first measurement report based on the first indication information, the first measurement report including the M measurement results that differ from the previous K measurement results.

[0016] In conjunction with the second aspect, in one possible implementation, the K measurement results correspond to K identifiers, where K equals N; the first measurement report also includes M identifiers corresponding to the different M measurement results, which are used to indicate the M measurement results that are different from the K measurement results among the N measurement results.

[0017] In conjunction with the second aspect, in one possible implementation, receiving the first measurement report based on the first indication information includes: sending a first resource indication based on the first indication information, the first resource indication indicating a first resource corresponding to the different M measurement results; and receiving the first measurement report through the first resource.

[0018] In conjunction with the second aspect, in one possible implementation, the first indication information is further used to indicate the activation of a second resource, which corresponds to the different M measurement results; receiving the first measurement report based on the first indication information includes receiving the first measurement report through the second resource.

[0019] In conjunction with the second aspect, in one possible implementation, the first indication information and / or the second indication information are carried in an uplink control message UCI or a media access control-control element MAC CE.

[0020] It should be noted that the technical solution of the second aspect of this application may correspond to the solution of the first aspect, and the relevant beneficial effects can be referred to the beneficial effects of the first aspect.

[0021] The third aspect discloses a communication method that can be applied to a user equipment, a component within the user equipment (e.g., a processor, chip, chip system, circuit, or functional module), or a logic module or software capable of implementing all or part of the user equipment's functions.

[0022] In this embodiment, the network device and the user equipment can store the measurement results reported by the user equipment. Therefore, for non-first-time measurement reports, the user equipment can compare the N measurement results obtained in this measurement with the K measurement results previously reported. If the N measurement results obtained in this measurement are different from the K measurement results previously reported, the user equipment can send a second indication message and the N measurement results to the network device. If the N measurement results obtained in this measurement are the same as the K measurement results previously reported, the user equipment can send a first indication message to the network device, without needing to send the N measurement results obtained in this measurement to the network device. The network device can then retrieve the N measurement results from the stored K measurement results previously reported by the user equipment based on the second indication message. This reduces the amount of data sent by the user equipment to the network device, eliminates unnecessary signaling overhead, and thus saves air interface resources.

[0023] In conjunction with the third aspect, in one possible implementation, the method further includes: receiving a first resource indication for indicating a first resource; the sending of the first measurement report includes: sending the first measurement report through the first resource.

[0024] In conjunction with the third aspect, in one possible implementation, the second indication information is also used to indicate the activation of the second resource; the sending of the first measurement report includes sending the first measurement report through the second resource.

[0063] This application discloses a communication method, apparatus, and computer-readable storage medium, which can reduce measurement reporting overhead and save air interface resources. The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0064] To better understand the embodiments of this application, the relevant content, terms or nouns involved in this application will be briefly introduced below.

[0065] I. Beamforming

[0066] Beamforming is a signal processing technique based on antenna arrays. By adjusting the weights and / or phases of the antenna array, beamforming can form a directional beam, which can concentrate signal energy in a certain direction for transmission. This can improve beam gain, effectively enhance coverage, reduce interference to the surrounding environment, and improve communication performance.

[0067] For example, in a 5G system, the operating frequency bands include frequency range (FR) 1 and frequency range 2 (FR2). The FR2 band uses higher frequencies, such as millimeter wave bands, resulting in greater transmission path loss. Therefore, coverage is typically achieved through beamforming techniques. For instance, multi-beam deployment can be used to achieve cell coverage.

[0068] II. Mobility Management

[0069] Mobility management is a crucial component of wireless mobile communication, determining the smooth handover and stable connection of user equipment (UE) between different cells and beams. When the UE is in idle or deactivated mode, mobility management primarily involves cell selection and cell reselection; when the UE is in connected mode, mobility management primarily involves handover. However, all three processes—cell selection, cell reselection, and handover—require measurements from the UE (such as beam measurements).

[0070] Mobility measurement and reporting are fundamental to mobility management. In mobile communication systems, the network sends measurement configurations to user equipment (UEs). UEs can measure reference signals (RS) according to these configurations and report measurement data to the network. Measurement reports can be at the cell level or beam level. The network can then perform mobility decisions, carrier management, beam management, and other functions based on these reports. The type of reference signal (RS-Type) can include at least one of synchronization signal block (SSB) and channel state information reference signal (CSI-RS). The quality metrics of the measured reference signal can include one or more of reference signal received power (RSRP), reference signal received quality (RSRQ), and signal-to-interference plus noise ratio (SINR), etc., which are not limited in this embodiment.

[0071] Furthermore, measurement reporting mechanisms can include periodic reporting, semi-persistent reporting, aperiodic reporting, and event reporting. Event reporting, in particular, involves user equipment reporting measurement data to the network when specific events occur; these events can be configured by the network. For a more detailed description of these reporting mechanisms, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP).

[0072] In mobility management, L1 / L2 triggered mobility (LTM) is a technology that can be used for cell handover. Layer 1 (L1) can refer to the physical layer (PHY), and Layer 2 (L2) can refer to one or more of the medium access control (MAC), radio link control (RLC), packet data convergence protocol (PDCP), and service data adaptation protocol (SDAP) layers. However, in L1 / L2 handover, L2 usually refers to the MAC layer. During LTM (Level 1 Transmission Management), handover-related operations primarily occur at L1 and L2 levels. For example, the user equipment (UE) can send L1 measurement results to the network device via uplink physical layer control signaling. This uplink physical layer control signaling can be carried on the physical uplink control channel (PUCCH) or the physical uplink shared channel (PUSCH), and can include uplink control information (UCI). After receiving the L1 measurement results from the UE, the network device can make a handover decision based on the L1 measurement results and send the handover decision to the UE via L1 / L2 handover command. The L1 / L2 signaling can be carried on the physical downlink control channel (PDCCH) and can be downlink control information (DCI) or a Media Access Control Protocol (MAC) control element (MAC CE).

[0073] III. Measurement Reporting Mode.

[0074] When a user equipment needs to report a measurement report (such as when an event is triggered), the process of transmitting the measurement report to the network device can be divided into two modes: Mode A and Mode B. These two modes are described below with reference to Figure 1.

[0075] As shown in Figure 1, in Mode A, when the UE needs to report a measurement report (e.g., after triggering an event report), the UE can send an indication message (e.g., a 1-bit indication message) to the network device on the PUCCH. This indication message notifies the network device that the UE is about to report a measurement report (e.g., a beam report). After receiving this indication message, the network device can send a DCI to the UE. This DCI indicates the resources (e.g., time-frequency domain resources) that the UE will use when subsequently sending uplink control information (UCI). In other words, the DCI allocates reporting resources to the UE. Afterwards, the UE can send the UCI using the resources indicated by the DCI. This UCI includes the measurement report (e.g., the specific event reporting content).

[0076] In Mode B, when the UE needs to report a measurement report (e.g., after triggering an event report), the UE can send an indication message (e.g., a 1-bit indication message) to the network device on the PUCCH. This indication message notifies the network device that the UE is about to report a measurement report (e.g., a beam report). Subsequently, the UE can use pre-configured resources (e.g., time-frequency domain resources) to report the measurement report in the next UCI. Correspondingly, after receiving the indication message, the network device knows that the UE is about to report a measurement report and can then receive the measurement report using the resources pre-configured for the UE.

[0077] IV. Measurement Reporting Content

[0078] For example, the UE measurement report may include information about the L best reference signals measured, such as the identifiers (reference signal-type identifiers, RS-Type IDs) of the L best reference signals and their corresponding quality metrics (such as one or more of RSRP, RSRQ, SINR, etc.), where L is a positive integer. The value of L can be configured by the network. For example, the network can send a measurement configuration to the UE via an RRC message, which may include the L value. In some cases, a reference signal may correspond to a transmit beam of the access network device.

[0079] Understandably, after the network sends the measurement configuration to the UE, the UE may perform multiple measurements according to the configuration, and report the measurement results to the network after each measurement. For example, for L1 measurements, the UE can report multiple measurement reports, each of which can include measurement results for multiple beams to indicate the signal quality of different beams within the measurement range. In this case, the UE requires a significant amount of uplink resources to report the measurement reports. Therefore, how to optimize the measurement report reporting strategy and reduce uplink resource consumption is a problem worthy of in-depth research.

[0080] Furthermore, in some scenarios, such as when the UE moves back and forth between two transmission beams or remains stationary, the content of the measurement reports submitted by the UE multiple times may be exactly the same or partially the same. In other words, in these scenarios, the UE may repeatedly report the same information. For example, please refer to Figure 2, which is a schematic diagram of a measurement reporting process in Mode A disclosed in an embodiment of this application. As shown in Figure 2, the process may include the following steps:

[0081] 201. The network device sends the measurement configuration to the user equipment.

[0082] The measurement configuration may include the number L of reference signals with the best signal quality that need to be reported, such as L being 4. For example, the measurement configuration may also include events configured for the user equipment.

[0083] 202. User equipment confirmation event triggered.

[0084] 203. User equipment sends instruction information to network equipment 1.

[0085] After the user equipment determines that an event has been triggered, that is, after the user equipment triggers the event reporting, the user equipment can send indication information 1 to the network device. Indication information 1 can be used to notify the network device that the user equipment is about to report a measurement report (such as a beam report).

[0086] 204. Network devices send downlink control information to user equipment.

[0087] After receiving indication information 1 from the user equipment, the network device can send downlink control information to the user equipment. This downlink control information can be used to indicate the reporting resources allocated to the UE.

[0088] 205. User equipment reports measurement report 1 to network equipment.

[0089] After receiving downlink control information from the network device, the user equipment can report measurement report 1 to the network device through the reporting resources indicated by the downlink control information. Measurement report 1 may include the target measurement results obtained by the user equipment based on the measurement configuration, such as the correlation measurement results of the four optimal reference signals, as shown in Figure 2. In this embodiment, the target measurement results may be the measurement results that need to be reported to the network device. Therefore, the target measurement results may also be referred to as the measurement results to be reported, or simply the measurement results to be reported below.

[0090] 206. User equipment confirmation event triggered.

[0091] After the event reporting is triggered in step 202, the user equipment can trigger the next event reporting.

[0092] 207. User equipment sends instruction information to network equipment 1.

[0093] After the user equipment triggers another event report, the user equipment can send indication information 1 to the network device. Indication information 1 can be used to notify the network device that the user equipment is about to report a measurement report (such as a beam report).

[0094] 208. The network device sends downlink control information to the user equipment.

[0095] 209. User equipment reports measurement reports to network equipment.

[0096] After receiving downlink control information from the network device, the user equipment can report Measurement Report 2 to the network device through the reporting resources indicated by the downlink control information. Measurement Report 2 may include the target measurement results obtained by the user equipment based on the measurement configuration, such as the related measurement results of the four optimal reference signals, as shown in Figure 2. It should be understood that the measurement results in Measurement Report 1 and Measurement Report 2 were obtained at different time domain resources / times / time periods. For example, the network device may periodically send reference signals, and the terminal device may periodically measure the reference signals and periodically report the measurement results.

[0097] As can be seen, in the above process, the content of the measurement reports submitted by the user equipment in two consecutive reports is the same. This repeated transmission of the same information will increase unnecessary signaling overhead and also lead to the occupation of a large amount of air interface resources.

[0098] In this embodiment, to reduce reporting overhead, for non-first-time measurement reports, the user equipment (UE) can compare the current measurement result to be reported (hereinafter referred to as the current measurement result to be reported) with previously reported measurement results. If the current measurement result to be reported is the same as the previously reported measurement result, the UE can indicate to the network device that the current measurement result to be reported is the same as the previously reported measurement result, and does not need to be explicitly reported, i.e., it does not need to send the current measurement result to the network device. Then, the network device can retrieve the current measurement result to be reported from the stored measurement results based on the UE's instruction. In this way, the UE does not need to send the complete measurement result to be reported to the network device, which can save air interface resources, reduce or eliminate unnecessary signaling overhead, thereby improving the overall network performance.

[0099] To better understand the embodiments of this application, the system architecture of the embodiments of this application will be described below.

[0100] Please refer to Figure 3, which is a schematic diagram of a communication system provided in an embodiment of this application. As shown in Figure 3, the communication system may include one or more network devices and one or more user equipments (one is shown as an example in Figure 3). The user equipment may be located within the coverage area of ​​one or more cells (carriers) managed by the network devices, and there may be one or more cells providing services to the user equipment. When there are multiple cells providing services to the user equipment, the user equipment may operate in a carrier aggregation (CA), dual connectivity (DC), or cooperative multipoint transmission manner. At least one of the multiple cells can provide at least two sets of parameters (numerology) to simultaneously provide radio resources to the user equipment. For example, as shown in Figure 3, user equipment #1 may be simultaneously located within the coverage area of ​​a cell managed by network device #1, a cell managed by network device #2, and a cell managed by network device #3. Exemplarily, network device #1 may be a macro base station (such as a macro gNB or macro g-NodeB), and network devices #2 and #3 may be micro base stations (such as small gNB or small g-NodeB). The user equipment and network devices are described below.

Wireless terminals in smart home devices (such as refrigerators, televisions, air conditioners, and electricity meters), smart robots, workshop equipment, wireless terminals in self-driving vehicles, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, or wireless terminals in smart homes, flying equipment (such as smart robots, hot air balloons, drones, and airplanes), or other devices that can access the network.Terminal devices can be fixed or mobile, and can be deployed on land, including indoors or outdoors, handheld, wearable or vehicle-mounted; they can also be deployed on water (such as ships); and they can also be deployed in the air (such as airplanes, balloons and satellites).

[0102] Network equipment can be access network equipment, which can be a radio access network (RAN) node (or device) that connects terminal devices to a wireless network. Network equipment can include, but is not limited to: base station (BS), radio network controller (RNC), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home evolved Node B, or home Node B, HNB), baseband unit (BBU), wireless fidelity (Wi-Fi) access point (AP), wireless relay node, wireless backhaul node, and transmission and reception point (TRP; or transmission point, TP). A base station is a device deployed in a radio access network that provides wireless communication functions; it can also be called base station equipment, such as an evolved Node B (eNB or e-NodeB) in an LTE system, a Node B (NB), a base station (gNodeB or gNB) in a 5G system, and a base station in a 6G system. A base station can include a Base Station Unit (BBU) and a Remote Radio Unit (RRU). The BBU and RRU can be located in different locations; for example, the RRU can be deployed remotely to a high-traffic area, while the BBU is located in a central equipment room. Alternatively, the BBU and RRU can be located in the same equipment room. The BBU and RRU can also be different components within the same rack. Base stations can take the following forms: macro base stations, micro base stations (also known as small cells), pico base stations, relay stations, access points, balloon stations, etc.

[0103] In some deployments, access network devices (such as gNBs) may include centralized units (CUs) and / or distributed units (DUs). Access network devices may also include radio units (RUs). Please refer to Figure 4, which is a schematic diagram of a CU-DU separation architecture (also known as a distributed deployment architecture) used in an access network device according to an embodiment of this application. As shown in Figure 4, the access network device logically may include one CU and one or more DUs. Each DU can be connected to the CU via an F1 interface, and information exchange between different DUs can be completed based on forwarding by the CU. The CU and DU can be physically set together or physically separated; this embodiment of the application does not limit this. The CU can implement some functions of the access network device (such as some protocol layer functions), the DU can implement some functions of the access network device (such as some protocol layer functions), and the CU can be used to control the operation of one or more DUs. For example, the CU can implement the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers, as well as the service data adaptation protocol (SDAP) layer. The DU can implement the functions of the radio link control (RLC) and media access control (MAC) layers, and can also implement some or all physical layer functions (such as the higher physical layer). The RU can be used to implement some physical layer functions (such as the lower physical layer) and radio frequency functions. For a detailed description of each of the above protocol layers, please refer to the relevant technical specifications of the 3rd Generation Partnership Project (3GPP). It is understood that in some possible implementations, the access network equipment can be a CU node, a DU node, or a device including both CU and DU nodes.

[0104] In some deployments of access network equipment, the CU can be further divided into CU-control plane (CP) and CU-user plane (UP), etc. In other deployments of access network equipment, the access network equipment can also be an open radio access network (ORAN) architecture, etc. This application does not limit the specific deployment method of the access network equipment.

[0105] It should be noted that although this application embodiment mainly uses the L1 measurement scenario as an example for illustration, this application embodiment is not limited to the measurement scenario. This application embodiment can be applied to all scenarios that require multiple reporting of measurement reports. For example, the technical solution provided by this application embodiment can be applied to reference signal handover (HO) technology, as well as other handover mobility management technologies, such as LTM handover. It should also be noted that the architecture shown in Figures 3 and 4 is only an exemplary illustration, and the architecture shown in Figures 3 and 4 may also include other devices / network elements / modules, which this application embodiment does not limit.

[0106] It is understood that the aforementioned access network devices, terminal devices, etc., can be implemented in the form of hardware, computer software, or a combination of hardware and computer software. For example, the aforementioned access network devices, terminal devices, etc., can be implemented by a single device, or by multiple devices working together, or by a functional module within a single device; this application embodiment does not specifically limit this.

The technical solutions in this application can also be applied to Universal Mobile Telecommunications System (UMTS), Code Division Multiple Access (CDMA) systems, Wireless Local Area Networks (WLANs), etc.

[0108] It should be noted that the system architecture, network architecture, and business scenarios (or application scenarios) described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the evolution of communication network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0109] To better understand the embodiments of this application, the overall concept of the embodiments of this application will be described by way of example below.

[0110] In this embodiment, to conserve air interface resources and improve measurement report reporting efficiency, for non-first-time measurement reports, the user equipment (UE) can first compare the current measurement result to be reported with previously reported measurement results (e.g., the last reported measurement result). If the current measurement result to be reported is the same as the previously reported measurement result, the UE can indicate to the network device that the current measurement result to be reported is the same as the previously reported measurement result, and does not need to send the current measurement result to the network device. Accordingly, the network device can determine that the current measurement result to be reported by the UE is the same as the previously reported measurement result based on the UE's instruction, and then retrieve the stored previously reported measurement results of the UE to obtain the current measurement result to be reported by the UE. The network device can then perform relevant processing (e.g., mobility determination) based on the current measurement result to be reported by the UE. Conversely, if the measurement result to be reported this time is different from the previously reported measurement result (partially different or completely different), the user equipment can indicate to the network device that the measurement result to be reported this time is different from the previously reported measurement result. Subsequently, the user equipment can send the measurement result to be reported this time to the network device, and the network device can perform relevant processing based on the measurement result to be reported received from the user equipment.

[0111] Furthermore, regarding the situation where the measurement results to be reported by the user equipment this time are different from the previously reported measurement results (such as the measurement results reported last time), it is possible that the measurement results to be reported by the user equipment this time (such as N measurement results) are partially different from the previously reported measurement results (such as K measurement results), that is, some measurement results are the same. In order to reduce the transmission of this part of the same content and further save air interface resources, in some possible implementations, after comparing the measurement results to be reported this time with the previously reported measurement results, the user equipment can indicate to the network device the number M of measurement results that are different between the measurement results to be reported this time and the previously reported measurement results. When M is greater than 0 and less than N, it indicates that the measurement result to be reported by the user equipment (UE) is partially the same as the previously reported measurement result. The UE can then send the M different measurement results from the previously reported results to the network device. It does not need to send the (NM) identical measurement results from the previously reported results. The network device can retrieve these (NM) measurement results from the stored previously reported measurement results of the UE, thus obtaining the current measurement result to be reported by the UE, and can then perform relevant processing based on this current measurement result. When M equals N, it indicates that the current measurement result to be reported by the UE is completely different from the previously reported measurement result. The UE can then send the current measurement result to the network device, and the network device can perform relevant processing based on the received current measurement result from the UE. When M equals 0, it indicates that the measurement results previously reported by the user equipment include the measurement results to be reported this time. Subsequently, the user equipment does not need to send the measurement results to be reported this time to the network device. The network device can obtain the corresponding measurement results from the previously reported measurement results of the user equipment and obtain the measurement results to be reported this time. Then, it can perform relevant processing based on the measurement results to be reported this time.

[0112] It should be understood that the two possible technical solutions described above have two approaches. One approach compares the current measurement result to be reported with previously reported measurement results, indicating to the network device the number M of measurement results that differ between the current and previously reported results (this is the technical solution corresponding to Figure 5). The other approach compares the current measurement result to be reported with previously reported measurement results, indicating to the network device whether the current and previously reported measurement results are the same or different (this is the technical solution corresponding to Figure 8). These two technical solutions will be described in detail below.

[0113] Please refer to Figure 5 first. Figure 5 is a flowchart illustrating a communication method disclosed in an embodiment of this application. In Figure 5, for non-first-time reporting, the user equipment can compare the measurement results to be reported this time (such as the N measurement results below) with the previously reported measurement results (such as the K measurement results below), and indicate to the network device the number M of measurement results that are different between the current measurement results to be reported and the previously reported measurement results. Based on the number of M, targeted processing can be performed. Specifically, as shown in Figure 5, this method may include, but is not limited to, the following steps:

[0114] 501. The network device sends measurement configuration to the user equipment.

[0115] For example, to perform mobility management for user equipment (UE), a network device can send a measurement configuration to the UE. Correspondingly, the UE can receive the measurement configuration from the network device. In some possible implementations, the measurement configuration can be sent via RRC messages / signaling.

[0116] It should be noted that the embodiments of this application do not specifically limit the parameters included in the measurement configuration. For example, the measurement configuration may include one or more of the following: the number L (e.g., 4) of the best measurement results to be reported, events configured for the user equipment, measurement objects, reporting configurations, measurement gaps, and SSB-based measurement timing configuration (SMTC). For example, the number of the best measurement results to be reported may be the number of reference signals with the best signal quality to be reported. A more detailed description of these configurations can be found in the relevant standards.

[0117] It should be understood that the network device can be an access network device or other devices, and the embodiments of this application do not limit this.

[0118] 502. The user equipment performs measurements based on the measurement configuration and obtains K measurement results.

[0119] After receiving the measurement configuration from the network device, the user equipment can perform measurements based on the configuration and obtain K measurement results. Here, K is a positive integer.

[0120] It should be understood that the above K measurement results can be measurement results to be reported, that is, measurement results that need to be notified to the network device. For example, a user equipment (UE) can perform measurements based on a measurement configuration to obtain relevant measurement results. The UE can then filter these measurement results to obtain filtered measurement results to be reported. For instance, the UE can measure eight reference signals (such as eight CSI-RS) on resources indicated by the network device, obtaining measurement results for the eight reference signals, such as the RSRP corresponding to the eight reference signals. Assuming the L value indicated in the measurement configuration is 4, in this case, the UE can filter out the four best reference signals from these eight reference signals based on their measurement results. The measurement results of these four best reference signals can be the measurement results to be reported. For example, suppose the IDs corresponding to these 8 reference signals are RS-Type ID 1 to RS-Type ID 8, and the measurement results corresponding to these 8 reference signals are (RS-Type ID 1: RSRP = 85), (RS-Type ID 2: RSRP = 82), (RS-Type ID 3: RSRP = 96), (RS-Type ID 4: RSRP = 100), (RS-Type ID 5: RSRP = 110), (RS-Type ID 6: RSRP = 90), (RS-Type ID 7: RSRP = 81), and (RS-Type ID 8: RSRP = 78). Among them, the IDs of the 4 reference signals with the best signal quality can be RS-Type ID 3, RS-Type ID 4, RS-Type ID 5, and RS-Type ID 6. That is, the measurement result to be reported can be the measurement result of these four reference signals. In this case, K can be 4. In some possible implementations, one RS-Type ID can correspond to the transmit beam of one network device, and the transmit beams of network devices corresponding to different RS-Type IDs can be the same or different.

[0121] In the above scenario, the number of measurement results to be reported is equal to the configured value L (e.g., K = L as described above). However, in some possible implementations, the number of measurement results to be reported may be less than or equal to the configured value. For example, the measurement results to be reported may need to meet specific requirements (e.g., RSRP, SINR, etc., must be greater than a certain threshold). If RSRP is required to be greater than or equal to 100, then the measurement results corresponding to RS-Type ID 3 and RS-Type ID 6 mentioned above do not meet the requirements. Therefore, the measurement results to be reported may include the measurement results corresponding to RS-Type ID 4 and RS-Type ID 5.

[0122] It should be understood that the type of reference signal measured by the user equipment may include one or more of SSB, CSI-RS, etc., and the quality index of the measured reference signal may include one or more of RSRP, RSRQ, SINR, etc., which are not limited in this application embodiment.

[0123] 503. The user equipment sends a second measurement report to the network equipment, the second measurement report including the measurement results of item K.

[0124] For example, the following description uses the K measurement results as the initial measurement results to be reported obtained based on the above measurement configuration. After obtaining the K measurement results, the user equipment can send a second measurement report to the network device, which may include the K measurement results. Accordingly, the network device can receive the second measurement report from the user equipment. For example, the second measurement report may include the measurement results of the above four optimal reference signals [(RS-Type ID 3: RSRP=96), (RS-Type ID 4: RSRP=100), (RS-Type ID 5: RSRP=110), (RS-Type ID 6: RSRP=90)]. For example, the measurement results may include the ID of the reference signal and the corresponding measurement value. For another example, the measurement results may include the ID of the cell and the corresponding measurement value. It should be understood that the measurement report may also include other information, which is not limited in this embodiment of the application, such as the type of reference signal.

[0125] It should be noted that, in this embodiment, after receiving the second measurement report, the network device can store the K measurement results carried in the second measurement report. This allows it to retrieve the same measurement result from the stored K measurement results when the subsequent measurement results to be reported include the same K measurement results. For example, the network device can store the K measurement results in memory, hard disk, or other storage media. Correspondingly, in this embodiment, the user equipment can also store the K measurement results, even after the user equipment has sent the K measurement results to the network device. This allows the user equipment to compare the obtained measurement results to be reported with the K measurement results after subsequent measurements, and then perform targeted processing, as detailed in the following description. For example, the user equipment can store the K measurement results in memory, hard disk, or other storage media.

[0126] Optionally, the multiple measurement results included in the measurement report sent by the user equipment to the network device can be arranged in order of signal quality from best to worst (e.g., in order of RSRP from largest to smallest), or in order of signal quality from worst to best (e.g., in order of RSRP from smallest to largest). This embodiment of the application does not limit this arrangement. For example, taking the arrangement in order of RSRP from largest to smallest as an example, the above four measurement results can be arranged in the following order: (RS-Type ID 5: RSRP = 110), (RS-Type ID 4: RSRP = 100), (RS-Type ID 3: RSRP = 96), (RS-Type ID 6: RSRP = 90). In some possible implementations, the multiple measurement results included in the measurement report sent by the user equipment to the network device can be reported in a differential form. For example, when arranged in descending order of RSRP, the four measurement results reported in differential form could be (RS-Type ID 5: RSRP = 110), (RS-Type ID 4: RSRP = -10), (RS-Type ID 3: RSRP = -4), and (RS-Type ID 6: RSRP = -6). It should be understood that the above descriptions regarding the reporting format are merely exemplary and do not constitute a limitation on the embodiments of this application.

[0127] In this embodiment, the mechanism for triggering a user equipment (UE) to report measurements can be periodic reporting, semi-persistent reporting, aperiodic reporting, event reporting, etc. For example, the network device may configure events for the UE, including event 1 and event 2. If the UE determines that event 1 or event 2 is satisfied based on the measurement results, the UE can report a measurement report to the network device. If the UE determines that event 1 or event 2 is not satisfied based on the measurement results, the UE does not need to report a measurement report to the network device. Examples of such events are given below:

[0128] Event A1: The signal quality of the serving cell (SC) becomes higher than an absolute threshold;

[0129] Event A2: The signal quality of the serving cell falls below an absolute threshold;

[0130] Event A3: The signal quality of a neighboring cell becomes higher than that of the primary cell (PCell) / primary secondary cell (PSCell) by an offset.

[0131] The serving cell mentioned above can be a cell that provides services (communication services) to the UE. The serving cell can be a PCell, PSCell, or secondary cell (SCell). For example, event 1 mentioned above can be event A1, and event 2 mentioned above can be event A3. It should be noted that the above descriptions of the events are merely illustrative and are not limited in this application embodiment. The relevant events can be defined by standards.

[0132] Furthermore, in this embodiment, the reporting mode adopted by the user equipment can be Mode A or Mode B. However, unlike the user equipment sending indication information 1 to indicate in Figure 2 above that the user equipment is about to report a measurement report, in this embodiment, in order to save reporting resources, for non-first-time reports, the user equipment can send indication information to the network device to indicate the number M of measurement results that are different from the previously reported measurement results. In this case, the user equipment does not need to send indication information 1 to the network device, or it can be understood that indication information 1 can be replaced by the indication information used to indicate M.

[0133] For example, in Mode A, for the initial measurement report, the user equipment sending a second measurement report to the network device may specifically include: the user equipment sending third indication information to the network device. This third indication information can be used to indicate the K value, that is, to indicate the number of measurement results to be reported this time. Then, the network device can allocate third resources to the user equipment based on the third indication information, such as through DCI, MACCE, or other downlink signaling. The user equipment can then send the second measurement report to the network device based on the third resources allocated by the network device. The third resources can correspond to K measurement results. In some possible implementations, the third indication information can also be used to indicate that the user equipment is about to report a measurement report.

[0134] In Mode B, for the initial measurement report, the user equipment (UE) sending a second measurement report to the network device may specifically include: the UE sending a fourth indication information to the network device. This fourth indication information can be used to indicate the K value, i.e., the number of measurement results to be reported this time. This fourth indication information can also be used to indicate the activation of a fourth resource. Subsequently, the UE can send the second measurement report to the network device through the fourth resource. The fourth resource can be a resource pre-configured by the network device for the UE, and the fourth resource can correspond to K measurement results. In some possible implementations, the fourth indication information may also be used to indicate that the UE is about to report a measurement report.

[0135] Optionally, the aforementioned third or fourth instruction information may be carried in PUCCH / PUSCH, such as in UCI, MACCE, or other uplink signaling.

[0136] It should be noted that although the above description uses the K measurement results as the first reported measurement results as an example, this application embodiment does not limit this. In some possible implementations, the above K measurement results may also be non-first reported measurement results. In this case, the user equipment can compare the K measurement results with previously reported measurement results, and then perform corresponding processing based on the comparison results. The processing flow corresponding to obtaining N measurement results can be referred to below.

[0137] It should be understood that steps 501 to 503 above are optional, and the embodiments of this application do not limit the specific circumstances of issuing measurement configurations and reporting the measurement results of item K.

[0138] 504. The user equipment performs measurements based on the measurement configuration and obtains N measurement results.

[0139] It is understandable that after the user equipment performs measurements based on the measurement configuration and obtains K measurement results, the user equipment can also perform measurements based on the measurement configuration to obtain N measurement results. That is, these N measurement results can be the measurement results obtained after the K measurement results based on the measurement configuration. For example, these N measurement results can be the measurement results to be reported obtained from this measurement. Here, N is a positive integer. When the number of measurement results to be reported obtained by the user equipment in each measurement is equal to the configured value L, N = K = L. When the number of measurement results to be reported obtained by the user equipment in each measurement is not necessarily equal to the configured value L, N can be less than or equal to L, and the relationship between N and K can include various cases, i.e., N > K, N = K, or N < K. <K。

[0140] 505. When the N measurement results are different from the previous K measurement results, the user equipment sends first indication information to the network equipment, and the first indication information is used to indicate the number of items M of the measurement results that are different between the N measurement results and the K measurement results.

[0141] After the user equipment obtains the N measurement results, it can compare the N measurement results with the previous K measurement results. When the N measurement results are different from the previous K measurement results, the user equipment can send first indication information to the network equipment. Correspondingly, the network equipment can receive the first indication information from the user equipment, and the first indication information can be used to indicate the number of items M of the measurement results that are different between the N measurement results and the K measurement results. Here, M is an integer greater than 0 and less than or equal to N.

[0142] In the embodiments of this application, the N measurement results being different from the previous K measurement results may mean that at least one of the N measurement results is different from the K measurement results, or it can also be understood that at least one of the N measurement results does not belong to the measurement results in the K measurement results. It should be understood that one measurement result can include multiple contents (such as the ID of the reference signal and the corresponding measurement value), and two measurement results being different can mean that at least one of the contents in the two measurement results is different. The content can also be referred to as a field or an attribute value. Exemplarily, taking the measurement results of the reference signal as an example, two measurement results being different can mean that at least one of the ID of the reference signal and the corresponding measurement value in the two measurement results is different. That is to say, when the ID of the reference signal and the corresponding measurement value in the two measurement results are both the same, it indicates that these two measurement results are the same.

[0143] When M = N, it indicates that each of the N measurement results is different from the K measurement results, that is, each of the N measurement results does not belong to the measurement results in the K measurement results, that is, the N measurement results and the K measurement results do not include the same measurement results. This situation is that the N measurement results and the K measurement results are completely different. When 0 < M < N, it indicates that the N measurement results and the K measurement results include (N - M) items of the same measurement results. This situation is that the N measurement results and the K measurement results are partially the same or partially different.

[0144] For example, suppose N = K = 4, the N measurement results include (RS-Type ID 5: RSRP = 110), (RS-Type ID 4: RSRP = 100), (RS-Type ID 2: RSRP = 92), and (RS-Type ID 3: RSRP = 82), and the K measurement results include (RS-Type ID 5: RSRP = 110), (RS-Type ID 4: RSRP = 100), (RS-Type ID 3: RSRP = 96), and (RS-Type ID 6: RSRP = 90). In this case, the measurement results that are different between the N measurement results and the K measurement results are the two measurement results (RS-Type ID 2: RSRP = 92) and (RS-Type ID 3: RSRP = 82). For another example, suppose K=3 and N=4, the N measurement results include (RS-Type ID 5: RSRP=110), (RS-Type ID 4: RSRP=100), (RS-Type ID 2: RSRP=92) and (RS-Type ID 3: RSRP=82), and the K measurement results include (RS-Type ID 5: RSRP=110), (RS-Type ID 4: RSRP=100) and (RS-Type ID 3: RSRP=96). In this case, the measurement results that are different between the N measurement results and the K measurement results are the two measurement results (RS-Type ID 2: RSRP=92) and (RS-Type ID 3: RSRP=82). For another example, suppose K=4, N=3, the N measurement results include (RS-Type ID 5: RSRP=110), (RS-Type ID 4: RSRP=100) and (RS-Type ID 2: RSRP=92), and the K measurement results include (RS-Type ID 5: RSRP=110), (RS-Type ID 4: RSRP=100), (RS-Type ID 3: RSRP=96) and (RS-Type ID 6: RSRP=90). In this case, the measurement result that is different from the N measurement results and the K measurement results is the measurement result (RS-Type ID 2: RSRP=92).

[0145] For example, the first indication information can also be used to indicate that the user equipment is about to send M measurement results that are different from the K measurement results to the network equipment.

[0146] It is understood that in this embodiment, the network device can store the aforementioned K measurement results. For example, the network device can store the measurement results reported by the user equipment in the most recent X reports, where any one of the X most recent reports can be one of the K measurement results, and X is a positive integer. For instance, when X is 1, the network device can store the most recently reported measurement result from the user equipment, i.e., the measurement result reported by the user equipment in the last time. In this case, the K measurement results can be the measurement results to be reported obtained from the user equipment's last measurement, and the N measurement results can be the measurement results to be reported obtained from the user equipment's current measurement. It is understood that after obtaining a new measurement result, the network device can store the new measurement result, and when the number of stored measurement results reaches the upper limit (e.g., X), the oldest measurement result can be deleted. In this embodiment, the value of X is not limited and can be set according to actual conditions. For example, if the measurement result to be reported this time is highly likely (e.g., greater than 90%) to be different from all the measurement results reported by user devices Q times ago, then X can be set to equal Q, where the value of Q can be obtained from historical statistics. For instance, suppose that based on historical statistics, it can be determined that the probability of a measurement result reported by a user device two times ago (two times ago before) being completely different from the measurement result to be reported this time is greater than 90%. That is, in the rounds two times ago, the rounds two times ago before that, and even earlier, the probability of a measurement result reported by a user device being completely different from the measurement result to be reported this time is greater than 90%. In this case, storing the measurement results reported by user devices two times ago is not very meaningful and can be omitted. Therefore, the value of X can be set to 2.

[0147] It should be understood that the above-mentioned content regarding the measurement results stored by the network device is merely illustrative and is not intended to limit the scope of this application. However, it should be noted that in this application embodiment, the user equipment can know which measurement results the network device stores, so that the user equipment can compare the measurement result to be reported with the measurement results currently stored by the network device, and then perform targeted measurement reporting. That is, the network device and the user equipment can store the same measurement results. For example, if the network device stores the measurement results reported by the user equipment X times most recently, then the user equipment can also store its own measurement results reported X times most recently. It should also be understood that when the measurement results stored by the user equipment and the network device include measurement results reported multiple times by the user equipment, the user equipment can compare the stored measurement results reported multiple times by the user equipment with the N measurement results, where the K measurement results can be the measurement results among the multiple reported measurement results that have the most identical items with the N measurement results. For example, suppose the network device and the user equipment currently store measurement result 1, measurement result 2, and measurement result 3. Measurement result 1 has 0 identical measurements with the N measurement results, measurement result 2 has 3 identical measurements with the N measurement results, and measurement result 3 has 1 identical measurement result with the N measurement results. Then, measurement result 2 can be any of the K measurement results. This minimizes the number of measurement results sent by the user equipment to the network device.

[0148] 506. The user equipment sends a first measurement report to the network equipment. The first measurement report includes M measurement results that are different from the N measurement results and the K measurement results.

[0149] After the user equipment sends the first instruction information to the network device, it can also send the first measurement report to the network device. Accordingly, the network device can receive the first measurement report from the user equipment based on the first instruction information. The first measurement report may include M measurement results that are different from the K measurement results among the N measurement results, that is, M measurement results that are not included in the K measurement results among the N measurement results.

[0150] The following is an exemplary description of the process for transmitting measurement reports between user equipment and network equipment.

[0151] In some possible implementations, when reporting measurements beyond the initial stage, after the user equipment (UE) indicates to the network device the number M of measurement results that differ from previously reported measurement results, the network device can allocate corresponding reporting resources to the UE based on the value of M. Then, the UE can send the M measurement results that differ from previously reported measurement results to the network device based on the allocated reporting resources. The smaller the value of M, the fewer reporting resources the network device can allocate to the UE; if M is 0, the network device does not need to allocate reporting resources to the UE. For example, after receiving the first indication information, the network device can send a first resource indication to the UE based on the first indication information. The first resource indication can be used to indicate a first resource, which can correspond to the M measurement results that differ from the K measurement results among the N measurement results. Accordingly, the UE can receive the first resource indication from the network device and then send a first measurement report to the network device based on the first resource indicated by the first resource indication. The network device can receive the first measurement report from the UE through the first resource. Understandably, the above method can be used for the process of transmitting measurement reports in Mode A mode.

[0152] In other possible implementations, when reporting measurements beyond the initial stage, the user equipment (UE) indicates to the network device the number M of measurement results that differ from previously reported measurement results in the current report. This implicitly instructs the UE to activate the corresponding reporting resource. The UE can then send the M measurement results that differ from previously reported measurement results to the network device based on the activated reporting resource. A smaller M value results in fewer activated reporting resources; if M is 0, the UE does not need to activate any reporting resources. For example, the first indication information can also be used to instruct the activation of a second resource, through which the UE can send a first measurement report to the network device. Correspondingly, the network device can receive the first measurement report from the UE through the second resource. The second resource can correspond to the M measurement results that differ from the K measurement results among the N measurement results. The second resource can be a pre-configured resource. For example, the network device can pre-configure reporting resources for the UE via RRC signaling, DCI, or other downlink signaling. Subsequently, when the UE needs to send a measurement report to the network device, it can activate the corresponding resource from the pre-configured reporting resources. Understandably, the above method can be used for the process of transmitting measurement reports in Mode B mode.

[0153] It should be noted that the relevant processes for transmitting measurement reports between the above user equipment and network equipment are only exemplary descriptions. The embodiments of this application do not limit the manner of network allocation of reporting resources, which can be pre-configured or dynamically allocated, etc. However, it should be understood that no matter which resource allocation method is used, in the embodiments of this application, compared with sending the complete N measurement results to the network device, less radio interface resources are required to send the different M measurement results among the N measurement results and the K measurement results to the network device, or less radio interface resources are required to send the different M measurement results and other relevant information (such as information for indicating the same measurement results among the K measurement results and the N measurement results) to the network device. Moreover, the smaller M is, the less radio interface resources may be required.

[0154] It can be understood that after the network device obtains the first measurement report, it can obtain the N measurement results based on the different M measurement results carried in the first measurement report. However, in the two cases of M = N and 0 < M < N, the processes for the network device to obtain the N measurement results based on the different M measurement results may be different, which will be described separately below.

[0155] Among them, in the case of M = N, the different M measurement results included in the first measurement report are also the N measurement results. In this case, the network device can directly obtain the N measurement results and then perform relevant processing (such as mobility decision) based on the N measurement results.

[0156] In the case of 0 < M < N, the different M measurement results included in the first measurement report are partial measurement results of the N measurement results. In this case, after the network device obtains the different M measurement results among the N measurement results and the K measurement results, it can obtain the N measurement results based on the different M measurement results and the stored K measurement results, and then perform relevant processing based on the N measurement results. Exemplarily, the network device can obtain the (N - M) measurement results that are the same among the K measurement results and the N measurement results from the stored K measurement results, and then can obtain the N measurement results based on the same (N - M) measurement results and the different M measurement results.

[0157] Understandably, when the measurement results stored by the user equipment and network equipment include measurement results reported multiple times by the user equipment, the user equipment can indicate to the network equipment which of the user equipment's reported measurement results stored by the network equipment is related to the measurement result to be reported this time (such as the N measurement results). For example, the user equipment can send a fifth indication message to the network equipment. This fifth indication message can be used to indicate the K measurement results currently stored by the network equipment, that is, the K measurement results related to the measurement result to be reported this time. Where M is not 0, the fifth indication message can also indicate that the different M measurement results are related to the K measurement results stored by the network equipment. For example, the fifth indication information can be carried in the first measurement report. The fifth indication information can be used to indicate the target measurement result among the measurement results reported multiple times by the user equipment stored by the network device. The target measurement result can be the K measurement results. The network device can obtain the K measurement results from the stored measurement results reported multiple times by the user equipment based on the fifth indication information, and then obtain the (NM) measurement results that are the same as the K measurement results and the N measurement results from the stored K measurement results. For example, suppose the network device and the user equipment currently store measurement result 1, measurement result 2 and measurement result 3. Measurement result 1, measurement result 2 and measurement result 3 can be the measurement results to be reported obtained by the user equipment from three measurements respectively. Measurement result 2 can be the K measurement results. Each measurement result (such as measurement result 1) currently stored by the network device and the user equipment can correspond to an identifier. In this case, the first measurement report sent by the user equipment to the network device may include fifth indication information (such as the identifier corresponding to measurement result 2). The fifth indication information can indicate measurement result 2. The network device can obtain the stored measurement result 2 based on the fifth indication information, that is, obtain the K measurement results. Then, it can obtain the K measurement results that are the same as (NM) measurement results among the N measurement results from the stored K measurement results.

[0158] The following describes the situation where a network device retrieves the same (NM) measurement result from the stored K measurement results as the same as the same (NM) measurement result from the N measurement results.

[0159] In this embodiment of the application, in order for the network device to obtain the complete N measurement results, the user equipment can also send relevant indication information to the network device to indicate the same (NM) measurement results among the K measurement results stored by the network device. For example, the first measurement report may also include sixth indication information, which can be used to indicate the same (NM) measurement results among the K measurement results stored by the network device. Accordingly, the network device can obtain the same (NM) measurement results among the stored K measurement results based on the sixth indication information, and then obtain the N measurement results based on the same (NM) measurement results and the different M measurement results.

[0160] It should be noted that the way the user equipment sends the sixth instruction information and different M measurement results to enable the network equipment to obtain the complete N measurement results can also be considered as the user equipment reporting the N measurement results obtained in this measurement.

[0161] In this application embodiment, the implementation method of the sixth indication information is not limited. For example, in one possible implementation, the K measurement results stored by the network device can correspond one-to-one with K identifiers, and the sixth indication information can be the identifier of the same (NM) measurement results. The identifier of the K measurement results can be a corresponding number; for example, the K measurement results can be numbered 1 to K in descending order. For example, this number can also be understood as a row number, with each measurement result corresponding to a row. For example, suppose K is 4, and the K measurement results include (RS-Type ID 5: RSRP = 110), (RS-Type ID 4: RSRP = 100), (RS-Type ID 3: RSRP = 96), and (RS-Type ID 6: RSRP = 90), corresponding to numbers 1 to 4 respectively. M is 2, and the same two measurement results could be (RS-Type ID 5: RSRP = 110) and (RS-Type ID 4: RSRP = 100). In this case, the sixth indication information could be (3, 4) to indicate the third and fourth measurement results. As another example, when K = N, the sixth indication information could be the M identifiers corresponding to the different M measurement results. These M identifiers can be used to indicate the M different measurement results among the K measurement results and the N measurement results. In other words, these M identifiers can also implicitly indicate the (NM) identical measurement results among the K measurement results and the N measurement results.

[0162] It can be understood that the content sent by the user equipment to the network equipment in the case of M = N is not exactly the same as that in the case of 0 < M < N. In the case of 0 < M < N, the user equipment can send the sixth indication information, while in the case of M = N, the user equipment does not send the sixth indication information. Therefore, the network equipment can distinguish the two cases of M = N and 0 < M < N based on whether the user equipment sends the sixth indication information. Further, when the number of items of the measurement results to be reported measured by the user equipment each time is equal to the configured value L, when M = L, it indicates that N = L. That is to say, in this case, when M = L, the network equipment can also determine that the different M items of measurement results included in the first measurement report are the N items of measurement results. And when the number of items of the measurement results to be reported measured by the user equipment each time is not necessarily equal to the configured value L, since both N and K are less than or equal to L, therefore, when M = L, it also indicates that N = L. That is to say, in this case, when M = L, the network equipment can also determine that the different M items of measurement results included in the first measurement report are the N items of measurement results.

[0163] It should be noted that the above fifth indication information and / or sixth indication information can be carried in the first measurement report or sent separately. The embodiments of the present application do not limit this.

[0164] 507. When the N items of measurement results are the same as the previous K items of measurement results, the user equipment sends the second indication information to the network equipment, and the second indication information is used to indicate that the N items of measurement results are the same as the K items of measurement results.

[0165] The user equipment compares the N items of measurement results with the previous K items of measurement results. When it is determined that the N items of measurement results are the same as the previous K items of measurement results, the user equipment can send the second indication information to the network equipment. Correspondingly, the network equipment can receive the second indication information from the user equipment, and the second indication information can be used to indicate that the N items of measurement results are the same as the K items of measurement results. Exemplarily, the case where the N items of measurement results are the same as the K items of measurement results is also the case where M = 0. That is to say, the second indication information can be used to indicate that the number of different measurement results in the N items of measurement results and the K items of measurement results is 0.

[0166] In the embodiments of the present application, the case where the N items of measurement results are the same as the previous K items of measurement results may be that each measurement result in the N items of measurement results is the same as the K items of measurement results, that is, each measurement result in the N items of measurement results belongs to the measurement results in the K items of measurement results.

[0167] It is understandable that after receiving the second indication information, the network device can retrieve the N measurement results from the K measurement results based on the second indication information, and then perform relevant processing based on the N measurement results. It is also understandable that, if the measurement results stored by the user equipment and the network device include measurement results reported multiple times by the user equipment, the user equipment can also indicate to the network device which of the user equipment's reported measurement results stored by the network device is related to the measurement result to be reported this time (such as the N measurement results). For example, the user equipment can send a fifth indication information to the network device, which can be used to indicate the K measurement results currently stored by the network device, that is, the K measurement results related to the measurement result to be reported this time. Accordingly, the network device can retrieve the stored K measurement results based on the fifth indication information, and then retrieve the N measurement results from the K measurement results.

[0168] In the two cases of K=N and K>N, the process by which the network device obtains the N measurement results from the K measurement results can be different, and will be explained below.

[0169] In the case where K=N, it indicates that the K measurement results correspond one-to-one with the N measurement results, meaning the K measurement results are completely identical to the N measurement results. In this case, the network device can directly obtain the N measurement results and then perform relevant processing (such as mobility decision-making) based on them. It should be understood that if the number of measurement results to be reported by the user equipment each time is equal to the configured value L, then N=K=L, meaning there will be no case where K>N. In this case, the network device can also determine that the number of measurement results to be reported by the user equipment each time is L.

[0170] When K > N, it indicates that the K measurement results include the N measurement results, as well as other measurement results besides the N measurement results. In this case, the network device can obtain the N measurement results from the K measurement results. The following explains the case where the network device obtains the N measurement results from the stored K measurement results.

[0171] In this embodiment of the application, in order for the network device to obtain the N measurement results from the K measurement results, the user equipment can also send a seventh indication information to the network device. The seventh indication information can be used to indicate N measurement results stored in the network device that are the same as the N measurement results, or to indicate (KN) measurement results stored in the network device that are different from the N measurement results. Accordingly, the network device can obtain the N measurement results from the stored K measurement results based on the seventh indication information.

[0172] It should be noted that the user equipment can also be considered to have reported the N measurement results obtained in this measurement by sending the second indication information, or by sending the second indication information and the seventh indication information to enable the network device to obtain the complete N measurement results.

[0173] In the embodiments of this application, the implementation manner of the seventh indication information is not limited. Exemplarily, in a possible implementation manner, the K measurement results stored by the network device can be in one-to-one correspondence with K identifiers. The seventh indication information can be the identifiers of the N measurement results that are the same as the N measurement results among the K measurement results stored by the network device, or can be the identifiers of the (K - N) measurement results that are different from the N measurement results among the K measurement results stored by the network device. Among them, the identifiers of the K measurement results can be corresponding numbers. For example, the K measurement results can be numbered 1 to K in descending order. For example, taking the seventh indication information as the identifiers of the N measurement results that are the same as the N measurement results among the K measurement results stored by the network device as an example, assuming K is 4 and N is 2, the K measurement results include (RS-Type ID 5: RSRP = 110), (RS-Type ID 4: RSRP = 100), (RS-Type ID 3: RSRP = 96), and (RS-Type ID 6: RSRP = 90), corresponding to numbers 1 to 4 respectively, and the N measurement results include (RS-Type ID 5: RSRP = 110) and (RS-Type ID 4: RSRP = 100). In this case, the seventh indication information can be (1, 2) to indicate the first and second measurement results among the K measurement results.

[0174] It can be understood that the content sent by the user equipment to the network device is not exactly the same in the case of K = N and the case of K > N. In the case of K > N, the user equipment can send the seventh indication information, while in the case of K = N, the user equipment does not send the seventh indication information. Therefore, the network device can distinguish the two cases of K = N and K > N based on whether the user equipment sends the seventh indication information.

[0175] It can be understood that in a possible implementation manner, the first indication information and the second indication information can be carried in a certain uplink message / signal. A certain field in the uplink message / signal can be defined as the number of items M of the measurement results that are different between the N measurement results and the K measurement results. M = 0 is the case of the second indication information, and 0 < M ≤ N is the case of the first indication information. Exemplarily, the first indication information and / or the second indication information can be carried on PUCCH / PUSCH, such as the first indication information and / or the second indication information can be carried in UCI or MAC CE.

[0176] For example, the second instruction information can also be used to instruct the user equipment not to report measurement reports in the future. The measurement results to be reported this time can be obtained based on the previously reported K measurement results, that is, the N measurement results.

[0177] In the above processing flow, both the network device and the user equipment can store the relevant measurement results reported by the user equipment. After the user equipment subsequently measures the measurement result to be reported, it can compare the result to be reported with the stored relevant measurement results and then report the measurement accordingly. Specifically, for measurement results that are identical to those in the stored relevant measurement results, the user equipment does not need to send them to the network device. Instead, it can instruct the network device to retrieve them from the currently stored relevant measurement results through relevant indication information. This reduces the amount of data that needs to be sent to the network device, eliminates unnecessary signaling overhead, and thus saves air interface resources.

[0178] Figure 5 above illustrates the process of the user equipment indicating the value M, but it includes the case where the number of measurement results to be reported by the user equipment in each measurement is equal to the configured value L, and the case where the number of measurement results to be reported by the user equipment in each measurement is not necessarily equal to the configured value L. To more clearly illustrate the embodiments of this application, Figure 6 below provides an exemplary illustration of the case where the number of measurement results to be reported by the user equipment in each measurement is equal to the configured value L. In Figure 6, K = N = L, the K measurement results can be the first measurement results, and the N measurement results can be the second measurement results.

[0179] Please refer to Figure 6 first. Figure 6 is a flowchart illustrating another communication method disclosed in an embodiment of this application. As shown in Figure 6, the method may include, but is not limited to, the following steps:

[0180] 601. The network device sends a measurement configuration to the user equipment, which includes the number L of the best measurement results that need to be reported.

[0181] 602. The user equipment performs measurements based on the measurement configuration to obtain a first measurement result, which includes L measurement results.

[0182] After receiving the measurement configuration from the network device, the user equipment can perform measurements based on the measurement configuration and obtain the first measurement result, which includes L measurement results.

[0183] It should be understood that the first measurement result mentioned above can be a measurement result to be reported, that is, a measurement result that needs to be notified to the network device.

[0184] It should be understood that the type of reference signal measured by the user equipment may include one or more of SSB, CSI-RS, etc., and the quality index of the measured reference signal may include one or more of RSRP, RSRQ, SINR, etc., which are not limited in this application embodiment.

[0185] 603. The user equipment sends a second measurement report to the network equipment, the second measurement report including the first measurement result.

[0186] It should be noted that, in this embodiment of the application, after the network device receives the second measurement report, it can store the first measurement result carried in the second measurement report so that when the measurement results to be reported later include the same measurement result as the first measurement result, the same measurement result can be obtained from the stored first measurement result.

[0187] In this embodiment of the application, the mechanism for triggering the user equipment to report measurements can be periodic reporting, semi-persistent reporting, aperiodic reporting, event reporting, etc., and this embodiment of the application does not limit this.

[0188] It should be understood that steps 601 to 603 above are optional, and the embodiments of this application do not limit the specific circumstances of issuing the measurement configuration and reporting the first measurement result.

[0189] 604. The user equipment performs measurements based on the measurement configuration to obtain a second measurement result, which includes L measurement results.

[0190] It is understood that after the user equipment performs measurements based on the measurement configuration and obtains the first measurement result, the user equipment can also perform measurements based on the measurement configuration to obtain a second measurement result. That is, the second measurement result can be a measurement result obtained after the first measurement result based on the measurement configuration, and the first and second measurement results can be obtained at different time domain resources / moments / time periods. For example, the second measurement result can be the measurement result to be reported obtained in this measurement.

[0191] 605. If the second measurement result is different from the previous first measurement result, the user equipment sends a first indication information to the network device, the first indication information being used to indicate the number M of measurement results that are different from the first measurement result.

[0192] After the user equipment obtains the second measurement result, it can compare the second measurement result with the previous first measurement result. When the second measurement result is different from the previous first measurement result, the user equipment can send a first indication message to the network device. Correspondingly, the network device can receive the first indication message from the user equipment. The first indication message can be used to indicate the number of items M of the measurement results that are different between the second measurement result and the first measurement result. Here, M is an integer greater than 0 and less than or equal to L.

[0193] In the embodiments of this application, the situation that the second measurement result is different from the previous first measurement result can be that at least one measurement result in the second measurement result is different from the first measurement result, that is, at least one measurement result in the second measurement result does not belong to the measurement results in the first measurement result.

[0194] When M = L, it indicates that each measurement result in the second measurement result is different from the first measurement result, that is, each measurement result in the second measurement result does not belong to the measurement results in the first measurement result, that is, the second measurement result and the first measurement result do not include the same measurement results. When M < L, it indicates that the second measurement result and the first measurement result include (L - M) items of the same measurement results, and include M items of different measurement results, that is, the second measurement result includes M measurement results that do not belong to the measurement results in the first measurement result, and the first measurement result includes M measurement results that do not belong to the measurement results in the second measurement result.

[0195] Exemplarily, the first indication message can also be used to indicate that the user equipment is about to send M measurement results to the network device, that is, the M measurement results that are different between the second measurement result and the first measurement result.

[0196] It can be understood that in the embodiments of this application, the network device can store the above-mentioned first measurement result. Exemplarily, the network device can store the measurement results reported by the user equipment in the most recent X times. Among them, the measurement result reported in a certain time in the measurement results reported by the user equipment in the most recent X times can be the first measurement result, and X is a positive integer. It should be understood that in the embodiments of this application, the user equipment and the network device can store the same measurement results. For example, if the network device stores the measurement results reported by the user equipment in the most recent X times, then the user equipment can also store its own measurement results reported in the most recent X times. It should also be understood that when the measurement results stored by the user equipment and the network device include the measurement results reported by the user equipment multiple times, the user equipment can respectively compare the stored measurement results reported by the user equipment multiple times with the second measurement result. Among them, the first measurement result can be the measurement result that includes the most same items with the second measurement result among the multiple reported measurement results.

[0197] The user equipment sends a first measurement report to the network device, and the first measurement report includes M measurement results that are different between the second measurement result and the first measurement result.

[0198] After the user equipment sends the first indication information to the network device, it may also send a first measurement report to the network device. Correspondingly, the network device may receive the first measurement report from the user equipment based on the first indication information, and the first measurement report may include M measurement results that are different between the second measurement result and the first measurement result.

[0199] In the embodiments of this application, the specific process for transmitting the measurement report between the user equipment and the network device is not limited, and the relevant description in step 506 above may be referred to.

[0200] It can be understood that after the network device obtains the first measurement report, it may obtain the second measurement result based on the M measurement results that are different carried in the first measurement report. However, in the two cases of M = L and M < L, the processes for the network device to obtain the second measurement result based on the M measurement results that are different may be different, and the following will be described separately.

[0201] Among them, in the case of M = L, the M measurement results that are different included in the first measurement report are also the second measurement result. In this case, the network device may directly obtain the second measurement result, and then may perform relevant processing (such as mobility determination) based on the second measurement result.

[0202] In the case of 0 < M < L, the M measurement results that are different included in the first measurement report are partial measurement results of the second measurement result. In this case, after the network device obtains the M measurement results that are different between the second measurement result and the first measurement result, it may obtain the second measurement result based on the M measurement results that are different and the stored first measurement result, and then may perform relevant processing based on the second measurement result. Exemplarily, the network device may obtain (L - M) measurement results that are the same between the first measurement result and the second measurement result from the stored first measurement result, and then may obtain the second measurement result based on the (L - M) measurement results that are the same and the M measurement results that are different.

[0203] It is understandable that, when the measurement results stored by the user equipment and the network equipment include measurement results reported multiple times by the user equipment, the user equipment can indicate to the network equipment which of the user equipment's reported measurement results stored by the network equipment is related to the measurement result to be reported this time (such as the second measurement result). For example, the user equipment can send a fifth indication message to the network equipment. This fifth indication message can be used to indicate the first measurement result currently stored by the network equipment, that is, the second measurement result related to the measurement result to be reported this time. Where M is not 0, the fifth indication message can also indicate that the different M measurement results are related to the first measurement result stored by the network equipment. For example, the fifth indication message can be carried in the first measurement report. This fifth indication message can be used to indicate the target measurement result among the multiple measurement results reported by the user equipment stored by the network equipment. The target measurement result can be the first measurement result. The network equipment can obtain the first measurement result from the stored multiple measurement results reported by the user equipment based on the fifth indication message, and then obtain the second measurement result and the same (LM) measurement result from the stored first measurement result.

[0204] The following describes the case where the network device retrieves the same (LM) measurement result from the stored first measurement result as the second measurement result.

[0205] In this embodiment of the application, in order for the network device to obtain the complete second measurement result, the user equipment may also send relevant indication information to the network device to indicate the same (LM) measurement result in the first measurement result stored by the network device. For example, the first measurement report may also include sixth indication information, which can be used to indicate the same (LM) measurement result in the first measurement result stored by the network device. Accordingly, the network device can obtain the same (LM) measurement result in the stored first measurement result based on the sixth indication information, and then obtain the second measurement result based on the same (LM) measurement result and the different M measurement results.

[0206] In the embodiments of this application, the implementation manner of the sixth indication information is not limited. Exemplarily, in a possible implementation manner, the K measurement results stored by the network device may correspond one-to-one with K identifiers. In one case, the sixth indication information may be the identifiers of the same (L - M) measurement results in the first measurement result. In this case, the sixth indication information may explicitly indicate the same (L - M) measurement results. In another case, the sixth indication information may be the identifiers of the different M measurement results in the first measurement result. In this case, the sixth indication information may implicitly indicate the same (L - M) measurement results. The identifier of the K measurement results may be the corresponding number. For example, the K measurement results may be numbered 1 to K in descending order. Exemplarily, this number may also be understood as the line number, and each measurement result may correspond to a line.

[0207] It can be understood that the content sent by the user equipment to the network device in the case of M = L is not exactly the same as that in the case of 0 < M < L. In the case of 0 < M < L, the user equipment may send the sixth indication information, while in the case of M = L, the user equipment does not send the sixth indication information. Therefore, the network device can distinguish the two cases of M = L and 0 < M < L based on whether the user equipment sends the sixth indication information.

[0208] It should be noted that the above fifth indication information and / or sixth indication information may be carried in the first measurement report or sent separately. The embodiments of this application do not limit this.

[0209] 607. When the second measurement result is the same as the previous first measurement result, the user equipment sends the second indication information to the network device, and the second indication information is used to indicate that the second measurement result is the same as the first measurement result.

[0210] The user equipment compares the second measurement result with the previous first measurement result. When it is determined that the second measurement result is the same as the previous first measurement result, the user equipment may send the second indication information to the network device. Correspondingly, the network device may receive the second indication information from the user equipment, and the second indication information may be used to indicate that the second measurement result is the same as the first measurement result. Exemplarily, the situation where the second measurement result is the same as the first measurement result is also the case of M = 0, that is, the second indication information may be used to indicate that the number of different measurement result items between the second measurement result and the first measurement result is 0.

[0211] In the embodiments of this application, the second measurement result being the same as the previous first measurement result may mean that each measurement result in the second measurement result is the same as the first measurement result.

[0212] It can be understood that after the network device obtains the second indication information, it can obtain the first measurement result based on the second indication information, and then can perform relevant processing based on the first measurement result. It can be understood that in the case where the measurement results stored in the user equipment and the network device include the measurement results reported by the user equipment multiple times, the user equipment can also indicate to the network device which measurement result reported by the user equipment the measurement result to be reported this time (such as the second measurement result) is related to. Exemplarily, the user equipment can send the fifth indication information to the network device, and the fifth indication information can be used to indicate the first measurement result in the measurement results currently stored in the network device, that is, the first measurement result related to the measurement result to be reported this time. Correspondingly, the network device can obtain the stored first measurement result based on the fifth indication information, and then can perform relevant processing based on the first measurement result.

[0213] It can be understood that in a possible implementation manner, the first indication information and the second indication information can be carried in a certain uplink message / signal, and a certain field in the uplink message / signal can be defined as the number of items M of different measurement results between the second measurement result and the first measurement result. M = 0 is the case of the second indication information, and 0 < M ≤ L is the case of the first indication information. Exemplarily, the first indication information and / or the second indication information are carried in UCI or MAC CE.

[0214] Exemplarily, the second indication information can also be used to indicate that the user equipment does not report a measurement report subsequently, and the measurement result to be reported this time, that is, the second measurement result, can be obtained based on the previously reported first measurement result (such as the last reported measurement result).

[0215] It should be understood that the above steps 601 to 607 are similar to the above steps 501 to 507, and the relevant descriptions in the above steps 501 to 507 can also be referred to.

[0216] The following takes event reporting as an example to respectively illustrate the relevant processes of the above Mode A and Mode B.

[0217] Please refer to Figure 7, which is a schematic diagram of measurement reporting in Mode A and Mode B according to another embodiment of this application. As shown in Figure 7, in Mode A, after the network device issues the measurement configuration, the user equipment can perform measurements based on the measurement configuration. The measurement configuration may include the number L of the best measurement results to be reported, such as L being 4. When the user equipment triggers an event report, the user equipment can send relevant indication information to the network device through PUCCH to indicate the number of measurement results to be reported. For the first event report, this indication information can be L. In this way, the network device can determine the L measurement results that the user equipment needs to upload in this measurement based on the value of L, and can allocate corresponding reporting resources to the user equipment through DCI. Subsequently, the user equipment can send the L measurement results obtained in this measurement to the network device through UCI based on the reporting resources allocated by the network device. For example, the L measurement results can be as shown in Figure 7. When the user equipment triggers an event report again, the user equipment can compare the L measurement results obtained in this measurement with the previously reported measurement results, and then process them accordingly. For example, let's take the comparison of L measurement results obtained in the current measurement with the L measurement results reported in the previous measurement as an example. After comparing the L measurement results obtained in the current measurement with the L measurement results reported in the previous measurement, the user equipment can send relevant indication information to the network device through PUCCH. This indication information can be used to indicate the number M of measurement results that are different between the L measurement results obtained in the current measurement and the L measurement results reported in the previous measurement.

[0218] Among them, when M = 0, the network device can determine that the L measurement results obtained in this measurement are the same as the L measurement results reported last time. The network device can obtain the L measurement results reported by the user equipment stored currently, and then can perform relevant processing based on the L measurement results. In this case, the network device does not need to allocate reporting resources for the user equipment. When 0 < M < L, the network device can determine that (L - M) measurement results among the L measurement results obtained in this measurement are the same as those in the L measurement results reported last time. The network device can allocate reporting resources corresponding to the M measurement results for the user equipment through DCI. Subsequently, the user equipment can send, through UCI to the network device, the M measurement results that are different between the L measurement results obtained in this measurement and the L measurement results reported last time, and can also send relevant indication information to indicate the (L - M) measurement results that are the same between the L measurement results obtained in this measurement and the L measurement results reported last time. Correspondingly, the network device can obtain the complete L measurement results obtained in this measurement based on the different M measurement results sent by the user equipment and the same (L - M) measurement results stored currently. For example, as shown in Figure 7, assume that the L measurement results obtained in this measurement include (RS-Type ID 5: RSRP = 110), (RS-Type ID 4: RSRP = 100), (RS-Type ID 2: RSRP = 92), and (RS-Type ID 3: RSRP = 82). In this case, the third and fourth items among the L measurement results obtained in this measurement are different from the third and fourth items in the L measurement results reported last time. Therefore, the user equipment can send the third and fourth items among the L measurement results obtained in this measurement to the network device, and send relevant indication information to indicate that the first and second items in the L measurement results reported last time are the same as the first and second items in the L measurement results obtained in this measurement. As shown in Figure 7, the user equipment can send (Line3: RS-Type ID 2: RSRP = 92) and (Line4: RS-Type ID 3: RSRP = 82) to the network device, or can send (Line3: RS-Type ID 2: RSRP = -8) and (Line4: RS-Type ID 3: RSRP = -10) in a differential form. Among them, "Line3" and "Line4" can be used to indicate the items that are different between the L measurement results obtained in this measurement and the L measurement results reported last time, and the content after "Line3" and "Line4" is the third and fourth items among the L measurement results obtained in this measurement.When M=L, the network device can determine that the L measurement results obtained by the user equipment in this measurement do not include the same measurement results as the L measurement results reported in the previous measurement. Based on the L value, the network device can determine that the user equipment needs to upload the L measurement results obtained in this measurement in the future. The network device can allocate corresponding reporting resources to the user equipment through DCI. Subsequently, the user equipment can send the L measurement results obtained in this measurement to the network device through UCI based on the reporting resources allocated by the network device.

[0219] As shown in Figure 7, in Mode B, after the network device issues the measurement configuration, the user equipment (UE) can perform measurements based on the configuration. The measurement configuration can include the number L of optimal measurement results to be reported, such as L = 4. When the UE triggers an event report, it can send relevant indication information to the network device via PUCCH to indicate the number of measurement results to be reported. For the first event report, this indication information can be L. This indication information can also be used to indicate the activation of the reporting resources corresponding to the L measurement results. In this way, the network device can determine based on the L value that the UE will activate the reporting resources corresponding to the L measurement results. Subsequently, the UE will send the L measurement results obtained in this measurement to the network device via UCI through the activated reporting resources. When the UE triggers an event report again, it can compare the L measurement results obtained in this measurement with the previously reported measurement results and then process them accordingly. For example, the comparison of the L measurement results obtained in this measurement with the previously reported L measurement results will be used as an example for explanation. After comparing the L measurement results obtained in this measurement with the L measurement results reported in the previous measurement, the user equipment can send relevant indication information to the network device through PUCCH. This indication information can be used to indicate the number M of measurement results that are different from the L measurement results reported in the previous measurement. This indication information can also be used to indicate the activation of the reporting resources corresponding to the M measurement results.

[0220] Among them, when M = 0, the reporting resources are not activated. The network device can determine that the L measurement results obtained this time are the same as the L measurement results reported last time. The network device can obtain the L measurement results reported by the user equipment stored currently, and then can perform relevant processing based on the L measurement results. When 0 < M < L, the indication information indicates to activate the reporting resources corresponding to M measurement results. Subsequently, the user equipment can send, via UCI to the network device, the M measurement results that are different between the L measurement results obtained this time and the L measurement results reported last time based on the activated reporting resources, and can also send relevant indication information to indicate the (L - M) measurement results that are the same between the L measurement results obtained this time and the L measurement results reported last time. Correspondingly, the network device can obtain the complete L measurement results obtained this time based on the different M measurement results sent by the user equipment and the same (L - M) measurement results stored currently. When M = L, the indication information indicates to activate the reporting resources corresponding to L measurement results. Subsequently, the user equipment can send, via UCI to the network device, the L measurement results obtained this time based on the activated reporting resources. Correspondingly, the network device can determine that there are no identical measurement results between the L measurement results obtained by the user equipment this time and the L measurement results reported last time based on the indication information, and the network device will subsequently upload the L measurement results obtained this time through the activated reporting resources.

[0221] Please refer to FIG. 8. FIG. 8 is a schematic flowchart of another communication method disclosed in an embodiment of the present application. In FIG. 8, the user equipment can indicate whether the measurement results to be reported this time are the same as or different from the measurement results reported previously to the network device by comparing the measurement results to be reported this time with the measurement results reported previously. In this manner, when the measurement results to be reported this time are the same as the measurement results reported previously, the user equipment may not send the measurement results to be reported this time to the network device, and the network device can obtain the corresponding measurement results from the measurement results reported by the user equipment stored previously. When the measurement results to be reported this time are different from the measurement results reported previously, the user equipment can send the measurement results to be reported this time to the network device. Specifically, as shown in FIG. 8, the method may include but is not limited to the following steps:

[0222] 801. The network device sends a measurement configuration to the user equipment, and the measurement configuration includes the number L of the best measurement results to be reported.

[0223] 802. The user equipment performs measurements based on the measurement configuration and obtains K measurement results.

[0224] It should be understood that the above K measurement results may be the measurement results to be reported, that is, the measurement results that need to be notified to the network device.

[0225] In this embodiment, the number of measurement results to be reported can all be equal to the configured value L, that is, K = N = L. It should be understood that the type of reference signal measured by the user equipment may include one or more of SSB, CSI-RS, etc., and the quality index of the measured reference signal may include one or more of RSRP, RSRQ, SINR, etc., which are not limited in this embodiment.

[0226] 803. The user equipment sends a second measurement report to the network equipment, the second measurement report including the measurement results of item K.

[0227] For example, the following description uses the K measurement results as the initial measurement results to be reported obtained based on the above measurement configuration. After obtaining the K measurement results, the user equipment can send a second measurement report to the network device, which may include the K measurement results. Accordingly, the network device can receive the second measurement report from the user equipment. It should be understood that the measurement report may also include other information, which is not limited in this embodiment, such as the type of reference signal.

[0228] Optionally, the multiple measurement results included in the measurement report sent by the user equipment to the network equipment can be arranged in order of signal quality from best to worst (e.g., in order of RSRP from largest to smallest), or in order of signal quality from worst to best (e.g., in order of RSRP from smallest to largest). This application embodiment does not limit this.

[0229] In this embodiment of the application, the mechanism for triggering the user equipment to report measurements can be periodic reporting, semi-persistent reporting, aperiodic reporting, event reporting, etc., and this embodiment of the application does not limit this.

[0230] Furthermore, in this embodiment, the reporting mode adopted by the user equipment can be Mode A or Mode B. However, unlike the user equipment sending indication information 1 in Figure 2 above to indicate that the user equipment is about to report a measurement report, in this embodiment, in order to save reporting resources, for non-first-time reports, the user equipment can send indication information to the network device to indicate whether the measurement result to be reported this time is the same as or different from the previously reported measurement result. In this case, the user equipment does not need to send indication information 1 to the network device, or it can be understood that indication information 1 can be replaced by the indication information used to indicate whether the measurement result to be reported this time is the same as or different from the previously reported measurement result.

[0231] For example, in Mode A, for the first measurement report, the user equipment sending a second measurement report to the network device may specifically include: the user equipment sending a second indication information to the network device, which can be used to indicate that the measurement result to be reported this time is different from the previously reported measurement result. Then, the network device can allocate corresponding reporting resources to the user equipment based on the second indication information, such as allocating corresponding reporting resources to the user equipment through DCI, MAC CE or other downlink signaling. The reporting resources can correspond to the L-item measurement result. Then, the user equipment can send a second measurement report to the network device based on the reporting resources allocated by the network device.

[0232] In Mode B, for the initial measurement report, the user equipment (UE) sending a second measurement report to the network device may specifically include: the UE sending a second indication message to the network device. This second indication message can be used to indicate that the measurement result to be reported this time is different from the previously reported measurement result. This second indication message can also be used to instruct the activation of the corresponding reporting resource, which can correspond to the L-item measurement result. Subsequently, the UE can send the second measurement report to the network device through the activated reporting resource. The activated reporting resource can be a resource pre-configured by the network device for the UE. For example, the second indication message can also be used to indicate that the UE is about to report a measurement report. The second indication message can be carried in PUCCH / PUSCH, such as in UCI, MAC CE, or other uplink signaling.

[0233] It should be noted that although the above description uses the K measurement results as the first reported measurement results as an example, this application embodiment does not limit this. In some possible implementations, the above K measurement results may also be non-first reported measurement results. In this case, the user equipment can compare the K measurement results with previously reported measurement results, and then perform corresponding processing based on the comparison results. The processing flow corresponding to obtaining N measurement results can be referred to below.

[0234] It should be understood that steps 801 to 803 above are optional, and the embodiments of this application do not limit the specific circumstances of issuing the measurement configuration and reporting the measurement results of item K.

[0235] 804. The user equipment performs measurements based on the measurement configuration and obtains N measurement results.

[0236] It is understandable that after the user equipment performs measurements based on the measurement configuration and obtains K measurement results, the user equipment can also perform measurements based on the measurement configuration to obtain N measurement results, where K=N. That is to say, the N measurement results can be the measurement results obtained based on the measurement configuration after the K measurement results, and the first measurement result and the second measurement result can be obtained at different time domain resources / time points / time periods.

[0237] It should be understood that steps 801 to 804 above are similar to steps 501 to 504 above, and the relevant descriptions in steps 501 to 504 above can also be referred to.

[0238] 805. If the N measurement results are different from the previous K measurement results, the user equipment sends a second indication message to the network equipment, the second indication message being used to indicate that the N measurement results are different from the K measurement results.

[0239] After obtaining N measurement results, the user equipment can compare these N measurement results with the previous K measurement results. If the N measurement results differ from the previous K measurement results, the user equipment can send a second indication message to the network device. Accordingly, the network device can receive the second indication message from the user equipment, which can be used to indicate that the N measurement results are different from the previous K measurement results.

[0240] In this embodiment of the application, the difference between the N measurement results and the previous K measurement results may be that at least one of the N measurement results is different from the K measurement results, that is, at least one of the N measurement results does not belong to the measurement results in the K measurement results.

[0241] For example, the second indication information can also be used to indicate that the user equipment is about to send the measurement results to be reported in this measurement to the network equipment, that is, the N measurement results.

[0242] It is understood that in this embodiment of the application, the network device may store the aforementioned K measurement results. For example, the network device may store the measurement results reported by the user equipment in the X most recent reports, where one of the X most recent reports by the user equipment can be one of the K measurement results, and X is a positive integer. For instance, when X is 1, the network device may store the measurement result most recently reported by the user equipment, that is, the measurement result reported by the user equipment in the last time. In this case, the K measurement results can be the measurement results to be reported obtained from the user equipment's last measurement, and the N measurement results can be the measurement results to be reported obtained from the user equipment's current measurement.

[0243] It should be understood that the above-mentioned content regarding the measurement results stored by the network device is merely illustrative and is not intended to limit the scope of this application. However, it should be noted that in this application embodiment, the user equipment can know which measurement results the network device stores, so that the user equipment can compare the measurement result to be reported with the measurement results currently stored by the network device, and then perform targeted measurement reporting. That is, the network device and the user equipment can store the same measurement results. For example, if the network device stores the measurement results reported by the user equipment X times most recently, then the user equipment can also store its own measurement results reported X times most recently. It should also be understood that when the measurement results stored by the user equipment and the network device include measurement results reported multiple times by the user equipment, the user equipment can compare the stored measurement results reported multiple times by the user equipment with the N measurement results, where the K measurement results can be the measurement results among the multiple reported measurement results that have the most identical items with the N measurement results.

[0244] 806. The user equipment sends a first measurement report to the network equipment, the first measurement report including the N measurement results.

[0245] After the user equipment sends the second instruction information to the network device, it can also send the first measurement report to the network device. Accordingly, the network device can receive the first measurement report from the user equipment based on the second instruction information, and the first measurement report may include the N measurement results.

[0246] The following is an exemplary description of the process for transmitting measurement reports between user equipment and network equipment.

[0247] In some possible implementations, when a measurement is reported for the first time, after the user equipment (UE) indicates to the network device that the measurement result to be reported this time is different from the previously reported measurement result, the network device can allocate corresponding reporting resources to the UE. These reporting resources correspond to the L measurement results to be reported this time. Then, the UE can send the measurement result to be reported to the network device based on the allocated reporting resources. For example, after receiving the second indication information, the network device can send a first resource indication to the UE based on the second indication information. The first resource indication can be used to indicate a first resource, which can correspond to the N measurement results. Accordingly, the UE can receive the first resource indication from the network device and then send a first measurement report to the network device based on the first resource indicated by the first resource indication. The network device can receive the first measurement report from the UE through the first resource. It is understood that the above method can be the process for transmitting measurement reports in Mode A.

[0248] In other possible implementations, when reporting measurements beyond the initial report, the user equipment (UE) indicates to the network device that the measurement result to be reported this time is different from the previously reported measurement results, and implicitly instructs the activation of the corresponding reporting resource. This reporting resource corresponds to the L measurement results to be reported this time. Then, the UE can send the measurement results to be reported to the network device based on the activated reporting resource. For example, the second indication information can also be used to instruct the activation of a second resource, through which the UE can send a first measurement report to the network device. Correspondingly, the network device can receive the first measurement report from the UE through the second resource. The second resource can correspond to the N measurement results. The second resource can be a pre-configured resource; for example, the network device can pre-configure the reporting resource for the UE through RRC signaling, DCI, or other downlink signaling. Then, when the UE needs to send a measurement report to the network device, it can activate the corresponding resource from the pre-configured reporting resources. It is understood that the above method can be the process for transmitting measurement reports in Mode B mode.

[0249] It should be noted that the above-described process for transmitting measurement reports between user equipment and network equipment is merely an illustrative example. This application does not limit the method of allocating reporting resources to the network; it can be pre-configured or dynamically allocated, etc.

[0250] Understandably, after receiving the first measurement report, the network device can perform relevant processing (such as mobility determination) based on the N measurement results carried in the first measurement report.

[0251] 807. If the N measurement results are the same as the previous K measurement results, the user equipment sends a first indication message to the network equipment, the first indication message being used to indicate that the N measurement results are the same as the K measurement results.

[0252] The user equipment (UE) compares the N measurement results with the previous K measurement results. If the UE determines that the N measurement results are the same as the previous K measurement results, it can send a first indication message to the network device. Accordingly, the network device can receive the first indication message from the UE, which can be used to indicate that the N measurement results are the same as the K measurement results.

[0253] In this embodiment of the application, the fact that the N measurement results are the same as the previous K measurement results can mean that the K measurement results and the N measurement results are in a one-to-one correspondence, that is, the K measurement results and the N measurement results are completely identical.

[0254] It is understandable that after receiving the first indication information, the network device can retrieve the N measurement results from the K measurement results based on the first indication information, and then perform relevant processing based on the N measurement results. It is also understandable that, if the measurement results stored by the user equipment and the network device include measurement results reported multiple times by the user equipment, the user equipment can also indicate to the network device which of the user equipment's reported measurement results stored by the network device is related to the measurement result to be reported this time (such as the N measurement results). For example, the user equipment can send a fifth indication information to the network device, which can be used to indicate the K measurement results currently stored by the network device, that is, the K measurement results related to the measurement result to be reported this time. Accordingly, the network device can retrieve the stored K measurement results based on the fifth indication information, and then retrieve the N measurement results from the K measurement results.

[0255] It should be noted that the way the user equipment sends the first instruction information to enable the network equipment to obtain the complete N measurement results can also be considered as the user equipment reporting the N measurement results obtained in this measurement.

[0256] Understandably, in one possible implementation, the first and second indication information can be carried in some uplink message / signaling. A field in this uplink message / signaling can be defined as whether the N measurement results are the same as or different from the K measurement results; for example, a field value of 0 represents the same, and a field value of 1 represents different. For instance, the first and / or second indication information may be carried in UCI or MAC CE.

[0257] For example, the first indication information and the second indication information mentioned above can each be 1 bit, where the first indication information is a first value and the second indication information is a second value, and the first value and the second value are different. For example, the first indication information is 0 and the second indication information is 1, or the first indication information is 1 and the second indication information is 0.

[0258] For example, the first indication information can also be used to instruct the user equipment not to report measurement reports in the future. The measurement results to be reported this time can be obtained based on the previously reported K measurement results, that is, the N measurement results.

[0259] In the above processing flow, both the network device and the user equipment can store relevant measurement results reported by the user equipment. After the user equipment subsequently measures the measurement result to be reported, it can compare the result to be reported with the stored relevant measurement results and then report the measurement accordingly. If the network device's currently stored relevant measurement results include the same measurement result as the one to be reported, the user equipment does not need to send the result to be reported to the network device. Instead, it can instruct the network device to retrieve the result from its currently stored relevant measurement results using relevant indication information. This reduces the amount of data that needs to be sent to the network device, eliminates unnecessary signaling overhead, and thus saves air interface resources.

[0260] The following examples illustrate the relevant processes of Mode A and Mode B, respectively, using event reporting as an example.

[0261] Please refer to Figure 9, which is a schematic diagram of measurement reporting under Mode A and Mode B modes disclosed in this application embodiment. Figure 9 illustrates an example of a user equipment comparing the L-item measurement results obtained in the current measurement with the previously reported L-item measurement results. Here, 0 indicates that the L-item measurement results obtained in the current measurement are different from the previously reported L-item measurement results, and 1 indicates that the L-item measurement results obtained in the current measurement are the same as the previously reported L-item measurement results. As shown in Figure 9, in Mode A mode, the indication information sent on the PUCCH for the initial event reporting can be 0. Thus, the network device can determine based on this indication information that the user equipment needs to subsequently upload the L-item measurement results obtained in the current measurement. It can allocate corresponding reporting resources to the user equipment through DCI, and subsequently, the user equipment can send the L-item measurement results obtained in the current measurement to the network device through UCI based on the reporting resources allocated by the network device. For example, the L-item measurement results can be as shown in Figure 9. When a user equipment (UE) triggers an event report again, it can compare the L-item measurement results obtained in this measurement with the previously reported L-item measurement results. The UE can send relevant indication information to the network device via PUCCH to indicate whether the current L-item measurement results are the same as or different from the previously reported L-item measurement results. Specifically, when the indication information is 1, the network device can determine that the current L-item measurement results are the same as the previously reported L-item measurement results. The network device can retrieve the currently stored L-item measurement results reported by the UE in the previous measurement and then perform relevant processing based on those L-item measurement results. In this case, the network device does not need to allocate reporting resources to the UE. When the indication information is 0, the network device can determine that the current L-item measurement results obtained by the UE do not include the same measurement results as the previously reported L-item measurement results. Based on this indication information, the network device can determine that the UE needs to upload the current L-item measurement results subsequently. The network device can allocate corresponding reporting resources to the UE via DCI, and the UE can then send the current L-item measurement results to the network device via UCI based on the reporting resources allocated by the network device.

[0262] As shown in Figure 9, in Mode B, for the initial event reporting, the indication information sent on the PUCCH can be 0. This indication information can also be used to indicate the activation of the reporting resource corresponding to the L-item measurement result. Thus, the network device can determine based on this indication information that the user equipment will activate the reporting resource corresponding to the L-item measurement result. Subsequently, the user equipment will send the L-item measurement result obtained in this measurement to the network device via the UCI through the activated reporting resource. When the user equipment triggers event reporting again, it can compare the L-item measurement result obtained in this measurement with the previously reported L-item measurement result. It can send relevant indication information to the network device via the PUCCH to indicate whether the L-item measurement result obtained in this measurement is the same as or different from the previously reported L-item measurement result. Specifically, when M is 1, the reporting resource is not activated. The network device can determine that the L-item measurement result obtained in this measurement is the same as the previously reported L-item measurement result. The network device can obtain the currently stored L-item measurement result previously reported by the user equipment and then perform relevant processing based on that L-item measurement result. When M is 0, this indication information indicates that the L-item measurement result obtained in this measurement is different from the L-item measurement result reported in the previous measurement, and indicates that the reporting resource corresponding to the L-item measurement result is activated. Subsequently, the user equipment can send the L-item measurement result obtained in this measurement to the network equipment through UCI based on the activated reporting resource.

[0263] It is understood that the technical solutions provided in this application can be used in the architecture of open RAN (O-RAN). The operations performed by the aforementioned network devices can be executed by nodes such as CU, DU, CU-CP, CU-UP, and RAN intelligent controller (RIC). Information sent by user equipment to access network devices can be sent to nodes such as CU, DU, CU-CP, CU-UP, or RIC (e.g., near-RT RIC), and this application does not limit this. RIC can include near-real-time RIC (near-RT RIC) and non-real-time RIC (non-RT RIC). For example, the following describes the application of the embodiment shown in Figure 5 in the O-RAN architecture.

[0264] Please refer to Figure 10, which is a flowchart illustrating another communication method disclosed in an embodiment of this application. As shown in Figure 10, the method may include, but is not limited to, the following steps:

[0265] 1001.CU sends measurement configuration to the user equipment.

[0266] For example, the CU can generate a measurement configuration, and then the CU can send the measurement configuration to the user equipment via the DU. For instance, the CU can receive a first request from the DU, and then generate a measurement configuration for the user equipment based on the first request, and then send the measurement configuration to the user equipment. The first request can be used to request the CU to generate a measurement configuration for the user equipment.

[0267] In some possible implementations, the DU can generate the measurement configuration, and then the DU can send the measurement configuration to the user equipment.

[0268] It should be understood that messages sent from the CU to the user equipment can be sent through the DU.

[0269] 1002. The user equipment performs measurements based on the measurement configuration and obtains K measurement results.

[0270] 1003. The user equipment sends a second measurement report to the DU, which includes the measurement results of item K.

[0271] 1004. The user equipment performs measurements based on the measurement configuration and obtains N measurement results.

[0272] 1005. If the N measurement results are different from the previous K measurement results, the user equipment sends a first indication information to the DU. The first indication information is used to indicate the number M of measurement results that are different from the previous K measurement results.

[0320] In one possible implementation, in the communication device shown in Figure 11, the processing unit can be one or more processors / logic circuits, and the communication unit can be a transceiver. Alternatively, the communication unit can also be a transmitting unit and a receiving unit, where the transmitting unit can be a transmitter and the receiving unit can be a receiver. The transmitting and receiving units are integrated into a single device, such as a transceiver. In this embodiment, the processor and transceiver can be coupled, etc., and the connection method between the processor and transceiver is not limited in this embodiment. During the execution of the above method, the process of sending information (such as sending a first measurement report) can be understood as the process of the processor outputting the information. When outputting the information, the processor outputs the information to the transceiver so that the transceiver can transmit it. After being output by the processor, the information may require further processing before reaching the transceiver. Similarly, the process of receiving information (such as receiving a first measurement report) in the above method can be understood as the process of the processor receiving the input information.

The communication unit can be an input / output interface, or it can be both an input interface and an output interface. The input / output interface can also be called a communication interface, an interface circuit, or an interface, etc.

The communication device 1200 may include a communication interface 1204 and at least one processor 1202. Optionally, it may also include a bus 1203. Further optionally, it may also include at least one memory 1201, wherein the memory 1201, the processor 1202 and the communication interface 1204 can be connected through the bus 1203.

[0323] The memory 1201 provides storage space, which can store data such as the operating system and computer programs. The memory 1201 can be one or a combination of several of the following: random access memory (RAM), read-only memory (ROM), erasable programmable read-only memory (EPROM), or compact disc read-only memory (CD-ROM).

[0324] Processor 1202 is a module that performs arithmetic and / or logical operations. Specifically, it can be one or a combination of processing modules such as a central processing unit (CPU), graphics processing unit (GPU), microprocessor unit (MPU), application-specific integrated circuit (ASIC), field-programmable gate array (FPGA), complex programmable logic device (CPLD), coprocessor (assisting the CPU in completing corresponding processing and applications), and microcontroller unit (MCU). For example, processor 1202 can be used to process communication protocols and communication data.

[0325] The communication interface 1204 is used to receive and / or transmit data to external sources. Optionally, the communication interface 1204 may also include a transmitter (such as an RF transmitter, antenna, etc.) and / or a receiver coupled to the interface. For example, the communication interface 1204 may include a control circuit and an antenna. The control circuit is mainly used for converting baseband signals to RF signals and processing RF signals. The antenna is mainly used for transmitting and receiving RF signals in the form of electromagnetic waves. When data needs to be transmitted wirelessly, the processor 1202 performs baseband processing on the data to be transmitted and outputs a baseband signal to the control circuit. The control circuit then performs RF processing on the baseband signal and transmits the RF signal outward in the form of electromagnetic waves through the antenna. When data is sent to the communication device, the control circuit receives the RF signal through the antenna, converts the RF signal into a baseband signal, and outputs the baseband signal to the processor 1202. The processor 1202 converts the baseband signal into data and processes the data.

[0326] In one possible implementation, the control circuitry and antenna can be set up independently of the processor performing baseband processing. For example, in a distributed scenario, the control circuitry and antenna can be arranged in a remote manner, independent of the communication device.
