Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0038] To better understand the beam measurement result reporting method and apparatus disclosed in the embodiments of this application, the communication architecture applicable to the embodiments of this application is described below.

[0039] Figure 1 is a schematic diagram of a communication architecture according to an embodiment of this application. As shown in Figure 1, the communication system 100 may include a terminal device 110 and a network device 120. The network device 120 can communicate with the terminal device 110 via an air interface. Multi-service transmission is supported between the terminal device 110 and the network device 120.

[0040] It should be understood that the embodiments of this application are only illustrated by way of example with communication system 100, but the embodiments of this application are not limited thereto.

[0041] In the communication system 100 shown in Figure 1, network device 120 may be an access network device that communicates with terminal device 110. The access network device can provide communication coverage for a specific geographical area and can communicate with terminal device 110 (e.g., UE) located within that coverage area.

[0042] Network device 120 may be an evolved Node B (eNB or eNodeB) in a Long Term Evolution (LTE) system, a Next Generation Radio Access Network (NG RAN) device, a base station (gNB) in an NR system, a radio controller in a Cloud Radio Access Network (CRAN), or a relay station, access point, vehicle-mounted device, wearable device, hub, switch, bridge, router, or network device in a future evolved Public Land Mobile Network (PLMN), etc.

[0043] Terminal device 110 can be any terminal device, including but not limited to terminal devices that are connected to network device 120 or other terminal devices via wired or wireless connections.

[0045] The wireless communication system 100 may further include a core network device 130 that communicates with the network device 120. This core network device 130 may be a 5G core network (5G Core, 5GC) device, such as an Access and Mobility Management Function (AMF), an Authentication Server Function (AUSF), a User Plane Function (UPF), or a Session Management Function (SMF). Optionally, the core network device 130 may also be an Evolved Packet Core (EPC) device for an LTE network, such as a Session Management Function + Core Packet Gateway (SMF+PGW-C) device. It should be understood that SMF+PGW-C can simultaneously implement the functions of both SMF and PGW-C. During network evolution, the aforementioned core network device may also be called by other names, or new network entities may be formed by dividing the core network functions; this embodiment does not limit this.

[0046] The various functional units in the communication system 100 can also establish connections through interfaces to achieve communication.

[0047] For example, terminal devices establish air interface connections with access network devices through the NR interface for transmitting user plane data and control plane signaling; terminal devices can establish control plane signaling connections with the AMF through the N1 interface; access network devices, such as next-generation radio access base stations (gNBs), can establish user plane data connections with the UPF through the NG-U interface (i.e., the N3 interface); access network devices can establish control plane signaling connections with the AMF through the NG-C interface (i.e., the N2 interface); the UPF can establish control plane signaling connections with the SMF through the N4 interface; the UPF can interact with the data network to exchange user plane data through the N6 interface; the AMF can establish control plane signaling connections with the SMF through the N11 interface; and the SMF can establish control plane signaling connections with the PCF through the N7 interface.

Optionally, the wireless communication system 100 may include multiple base stations, and each base station may include other numbers of terminal devices within its coverage area. This application embodiment does not limit this.

Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship. It should also be understood that "instruction" mentioned in the embodiments of this application can be a direct instruction, an indirect instruction, or an indication of a related relationship.

[0050] To facilitate understanding of the technical solutions of the embodiments of this application, the relevant technologies of the embodiments of this application are described below. The following relevant technologies are optional solutions and can be combined with the technical solutions of the embodiments of this application in any way, and they all fall within the protection scope of the embodiments of this application.

[0051] 1. LTM mechanism.

[0052] In 5G (5th Generation Mobile Networks or 5th Generation Wireless Systems), the 3rd Generation Partnership Project (3GPP) Release 18 supports the LTM (Least Term Tolerance) mechanism, optimizing the cell handover process, thereby further reducing handover latency, ensuring service continuity, and ultimately ensuring that user equipment can smoothly use network services while on the move. The specific LTM process is shown in Figure 2. In simple terms, the LTM execution steps can be divided into the following parts:

[0053] After a Radio Resource Control (RRC) connection is established between the User Equipment (UE) and the base station (gNB), and the UE is in connected state (RRC_CONNECTED), the UE executes S211 to send a measurement report to the base station. The UE reports the L3 (Layer 3, or RRC layer) measurement results or reports to the base station, and reports the signal quality of the current serving cell and candidate cells, such as Reference Signal Received Power (RSRP) and Reference Signal Received Quality (RSRQ).

[0054] Based on the measurement results, the base station determines to initiate the LTM process and triggers candidate cell preparation. Then, the base station executes S212, sending a reconfiguration message (RRC Reconfiguration message) to the user equipment. This message contains the LTM candidate cell configuration, and the number of candidate cells can be one or more.

[0055] The user equipment receives the reconfiguration message, stores the LTM candidate cell configuration, and executes S213 to send a reconfiguration complete message (RRC Reconfiguration Complete message) to the base station to confirm receipt of the reconfiguration message.

[0056] Steps S211 to S213 above constitute the LTM preparation stage.

[0057] Before receiving an LTM cell handover command, user equipment can perform uplink / downlink synchronization with the candidate cell in advance to reduce the interruption latency during the handover process, including:

[0058] S2141. Downlink synchronization between user equipment and candidate cells.

[0059] S2142. Uplink synchronization between user equipment and candidate cells.

[0060] Steps S2141 to S2142 above constitute the advance synchronization phase.

[0061] Next, the user equipment performs L1 (Layer 1, or physical layer) measurements on each candidate cell and executes S215 to send an L1 measurement report to the base station. The L1 measurement report includes more detailed L1 measurement results for each candidate cell.

[0062] S216. The base station sends a cell handover command to the user equipment. The base station determines the target cell based on the L1 measurement results reported by the user equipment and instructs the UE to hand over to the target cell through the Media Access Control (MAC) control element (CE).

[0063] If the user equipment does not currently have a valid tracking area (TA) or a state ID of the transmission configuration index (TCI) of the target cell, then upon receiving the LTM handover indication, the user equipment executes S217 to initiate a random access procedure to the target cell.

[0064] Steps S215 to S217 above constitute the process of LTM executing instructions.

[0065] S218, LTM completed, the user equipment sends an indication message to the base station indicating successful LTM completion. In the discussion of L1 event triggered measurement reports in version (R19), it was agreed to use MAC CE as the reporting format for measurement results. Considering the insufficient MAC CE resources, a truncated measurement report MAC CE will be used to report part of the measurement results.

[0066] It should be noted that, to save on MAC CE overhead, it is agreed to use differential values ​​(such as differential RSRP) to indicate beam measurement results. That is, the beam with the highest RSRP result is placed first among all beam measurement results, and the RSRP results of other beams are reported in differential form. On the other hand, when the UE uses truncated MR MAC CE, it needs to report more important information, such as the event ID, indicating which beam measurement result triggered the current report. Therefore, when using truncated MR MAC CE, the measurement results of the beam that triggered the current report must be considered.

[0067] In related technologies, for reporting beam measurement results, the terminal device measures the beams of each candidate cell and then uses a truncated (Medium Access Control, CE) control element as the reporting format. The measurement results of some candidate cell beams are reported in differential value form so that the network device understands the network status and makes a handover decision. However, this method requires placing the beam with the largest measurement result at the beginning of the MAC CE. When the beam with the largest measurement result is not the beam that triggered the current report, using a truncated MAC CE may result in missing the beam that triggered the current report.

[0068] Based on this, embodiments of this application provide a method, apparatus, device, chip, storage medium, and program product for reporting beam measurement results. A terminal device measures and evaluates at least one beam associated with one or more candidate cells and obtains the measurement result of a first beam that satisfies a triggering event. Further, the first information carrying the measurement result of the first beam is carried on a MAC CE and reported to a network device. In this way, the terminal device can use the MAC CE to prioritize reporting key information such as the measurement result of the beam that satisfies the measurement event to the network device, avoiding the loss of key information and thus improving the accuracy of the reporting.

[0069] To facilitate understanding of the technical solutions of the embodiments of this application, the technical solutions of this application are described in detail below through specific embodiments. The above-mentioned related technologies are optional solutions and can be arbitrarily combined with the technical solutions of the embodiments of this application, all of which fall within the protection scope of the embodiments of this application. The embodiments of this application include at least some of the following contents.

[0070] This application provides a method for reporting beam measurement results, as shown in Figure 3. This method may include, but is not limited to, the following steps:

[0071] S310, the terminal device sends first information, and correspondingly, the network device receives the first information; wherein, the first information is carried in the first MAC CE, and the first information includes at least the measurement result of the first beam that satisfies the triggering event, and the first beam is at least one beam associated with at least one candidate cell.

[0072] In this embodiment, the network device can be the network device currently accessed by the terminal device. Of course, the network device can also be the network device to which the serving cell of the terminal device belongs. This application does not impose any specific restrictions on this.

[0073] In this embodiment of the application, the terminal device may be a UE, and the network device may be a base station.

[0074] In this embodiment of the application, the first beam can be a specific beam among at least one beam associated with at least one candidate cell that meets the conditions for triggering an event, wherein the triggering event can be configured by the network device.

[0075] Understandably, there can be one or more candidate cells, and each candidate cell is associated with one or more beams to cover different areas.

[0076] In this embodiment of the application, the terminal device can measure at least one beam associated with one or more candidate cells, such as performing L1 measurement, to obtain the measurement results of all beams, wherein the measurement results of all beams include the measurement results of the first beam that satisfies the triggering event.

[0077] Here, after the terminal device obtains the measurement results of all beams, it acquires the first information, which can be achieved in the following way:

[0078] In one scenario, the terminal device determines the first beam from all beams whose measurement results satisfy the triggering event, and the measurement results of the first beam can be included in the first information.

[0079] In another scenario, the terminal device includes the measurement results of all beams in the first information. That is, the terminal device includes the measurement results of the first beam, as well as some or all of the measurement results of the remaining beams in the first information. The measurement results of the remaining beams include the measurement results of all beams except the measurement results of the first beam.

[0080] In another scenario, in addition to the first beam, the terminal device includes the best N measurements from all beams in the first information, where N is an integer greater than or equal to 1. N can be determined based on the number of measurements of all beams that the MAC CE can carry. For example, the number of all beams that the MAC CE can carry minus the number of the first beam is N. The number of all beams that the MAC CE can carry is configured by the network or agreed upon by the protocol.

[0081] In this embodiment of the application, the first information carried in the first MAC CE can be understood as the first MAC CE carrying the first information. The first MAC CE can be a truncated MAC CE carrying the measurement results of part of the beam, or it can be a MAC CE carrying the measurement results of all beams.

[0082] In this embodiment, the terminal device can send the first information in the following way: the terminal device can carry the first information in the first MAC CE and send it to the network device. It should be noted that since the MAC CE is a lightweight signaling structure that carries control information, when the first MAC CE is used to carry the first information containing the measurement results of the first beam, its internal structure contains specific fields to store measurement-related information, occupying fewer resources. The terminal device uses the MAC CE to transmit directly through the MAC layer, avoiding the signaling overhead of the RRC layer, and can quickly report the measurement results to the network device.

[0083] It should be noted that the measurement result of the beam carried in the MAC CE can be an absolute measurement value, or it can be the difference or differential component of the absolute measurement value of the beam relative to a reference measurement value. This application does not impose specific restrictions on this. The reference measurement value can be the absolute measurement value of the first beam (first absolute measurement value), or it can be the best absolute measurement value among all the absolute measurement values ​​of the beams (second absolute measurement value). The reference measurement value can also be configured by the network device or agreed upon by the protocol. This application does not impose restrictions on this.

[0084] It is understandable that, for a network device, upon receiving the first information sent by the terminal device, it determines whether the terminal device should perform cell handover based on the first information, and / or determines the target cell for the terminal device to perform cell handover.

[0085] Based on this, this application provides a method for reporting beam measurement results. A terminal device measures and evaluates at least one beam associated with one or more candidate cells, and obtains the measurement result of a first beam that satisfies a triggering event. Further, first information carrying the measurement result of the first beam is carried on a first MAC CE and reported to a network device. In this way, the terminal device can use the MAC CE to prioritize reporting key information, such as the measurement result of the beam that satisfies the measurement event, to the network device, improving transmission rate while saving resources. Simultaneously, the terminal device reports the first information to the network device, and the network device, based on the reported measurement result of the first beam, improves the accuracy of the reporting, thereby determining whether to trigger a handover or reselection, thus responding promptly to changes in network status and improving communication accuracy.

[0086] In some embodiments, the first information further includes: measurement results of at least one second beam, wherein the second beam is any beam other than the first beam among at least one beam associated with at least one candidate cell, and the measurement results of at least one second beam include the best measurement results.

[0087] In this embodiment of the application, the best measurement result is the measurement result of the beam with the best measurement result among all beams, wherein all beams include at least one beam associated with at least one candidate cell.

[0088] In this embodiment of the application, the measurement result of the first beam may be the best measurement result or it may not be the best measurement result.

[0089] In this embodiment of the application, the terminal device can obtain first information, which may further include: the measurement result of at least one second beam, wherein the second beam is any one of the remaining beams, and the remaining beams may be some or all of the beams other than the first beam among at least one beam associated with at least one candidate cell.

[0090] In one possible implementation, the terminal device may include the measurement results of the first beam and / or at least one second beam in the first information.

[0091] The measurement results of at least one second beam may include one or more of the following:

[0092] The best or optimal measurement result among all beam measurements;

[0093] Measurement results of beams originating from the same candidate cell as the first beam;

[0094] The beam measurement result is greater than the measurement threshold;

[0095] The best or optimal measurement result among the remaining beam measurements;

[0096] The measurement results of the first P beams in the remaining beam measurement results;

[0097] The measurement results of the first P beams in the sorted remaining beams.

[0098] In this application embodiment, the measurement threshold may be configured by the network device, predefined, or agreed upon by the protocol. This application does not impose any specific restrictions on this.

[0099] In this embodiment of the application, the best measurement result or optimal measurement result may be the highest measurement value among all the measurement results of all beams, or the highest measurement value among the measurement results of the remaining beams; wherein, all beams include at least one beam associated with at least one candidate cell, and the remaining beams include all beams except the first beam.

[0100] In this embodiment, the terminal device can sort the measurement results of the remaining beams, such as in descending order, to obtain the measurement results of the first P beams from the sorted remaining beams. Here, P is an integer greater than 1 and less than at least one beam associated with at least one candidate cell. Of course, the value of P can be determined by network device configuration or protocol agreement, or it can be determined based on the magnitude of the differential measurement values ​​of the remaining beams excluding the best measurement result, or it can be determined based on the size of the reported resources. This application does not impose specific limitations on this. In this way, the measurement results of the beam with the better measurement result and the measurement results of the first beam can both be transmitted to the network device, so that the network device can determine whether to trigger a handover or reselection based on the reported measurement results of the first beam and the measurement results of the beam with the better measurement result, thereby responding promptly to changes in network status.

[0101] In some embodiments, the measurement results contained in the area carrying the measurement results in the first MAC CE include one or more of the following:

[0102] Measurement results of the first beam;

[0103] The best measurement result among the measurements of at least one second beam;

[0104] Other measurement results from at least one second beam, excluding the best measurement result.

[0105] In the embodiments of this application, the measurement results of at least one second beam other than the best measurement result can be understood as part or all of the remaining measurement results of at least one second beam other than the best measurement result.

[0106] It is understandable that the measurement results of at least one second beam, excluding the best measurement result, can be sorted from highest to lowest or from largest to smallest. In this way, the terminal device can transmit the measurement results of the beam with the better measurement result and the measurement results of the first beam to the network device via MAC CE. This allows the network device to determine whether to trigger a handover or reselection based on the reported measurement results of the first beam and the beam with the better measurement result, thereby responding promptly to changes in network status and improving the accuracy of communication.

[0107] In this embodiment, the measurement results contained in the area carrying the measurement results in the first MAC CE may include only the measurement results of the first beam, or the measurement results of the first beam and the best measurement results; of course, it may also include the measurement results of the first beam and other measurement results from at least one second beam, or it may include the measurement results of the first beam, the best measurement results and the remaining measurement results. This application does not impose specific limitations on this.

[0108] In this embodiment of the application, the first beam and the second beam may be the same. For example, if the measurement result of the first beam is the best measurement result and the measurement result of at least one second beam includes the best measurement result, then the first beam and the second beam may be the same beam. When the measurement result of the first beam is not the best measurement result and the measurement result of at least one second beam includes the best measurement result, then the first beam and the second beam with the best measurement result may not be the same beam.

[0109] Understandably, the structure of a MAC CE includes a MAC CE header area and a field area for carrying information. The information carried in the field area includes, but is not limited to, measurement results, measurement reporting configuration identification information, indication information of whether measurement conditions / events are met, indication information of the number of beams that meet / do not meet measurement conditions / events, cell information, cell type information, and MAC CE type indication information.

[0110] Here, the measurement reporting configuration identifier information is used to clarify which measurement reporting configuration the measurement reporting is for, and to determine the measurement configuration / reference signal configuration corresponding to the reported content. The network device can report measurement data according to the predetermined configuration requirements based on this identifier information, and can also determine the corresponding reference signal information in the measurement results.

[0111] Here, the indication information of whether the measurement condition / event is met is used to carry the indication information in the MAC CE and feed it back to the network when the terminal device meets a certain measurement condition / or triggers a measurement event.

[0112] Here, the beam count indication information for meeting / not meeting measurement conditions / events includes: beam count indication information for meeting measurement conditions / events, and / or beam count indication information for not meeting measurement conditions / events. By carrying the beam count indication information for meeting and / or not meeting measurement conditions / events in the MAC CE and feeding it back to the network, the network can quickly understand the effectiveness of the beams, so as to make adjustments to cell handover and / or resource allocation and scheduling.

[0113] Here, cell information can be a cell identifier or a cell index. It's important to note that each cell has a unique identifier. Through this cell information, the network can accurately identify different cells, enabling collaborative management between cells and handover control of terminal devices between different cells.

[0114] Here, cell type information includes Primary Cell (PCELL), Secondary Cell (SCELL), and Primary Secondary Cell (PSCELL). Different types of cells perform different functions in the communication system. For example, the primary cell is responsible for providing basic communication services and control signaling, while the secondary cell is used to extend capacity and coverage. By carrying the cell type information in the MAC CE, network devices can rationally allocate resources and optimize communication performance based on the characteristics of the cells.

[0115] Here, the MAC CE type indication information is used to indicate whether the MAC CE is truncated or untruncated. Truncated and untruncated MAC CEs differ in data transmission and processing methods. By carrying the MAC CE type indication information within the MAC CE and feeding it back to the network device, the network device can correctly interpret the information carried by the MAC CE, ensuring the accuracy and integrity of data transmission.

[0116] In some embodiments, the location of the measurement result in the first MAC CE includes one or more of the following:

[0117] The measurement results of the first beam are located at the foremost position in the area carrying the measurement results in the first MAC CE;

[0118] The measurement result of the first beam is located at the first position in the area carrying the measurement result in the first MAC CE, and the first position is after the foremost position;

[0119] The best measurement result is located at the foremost position in the area carrying the measurement result in the first MAC CE;

[0120] The optimal measurement result is located at a second position in the area carrying the measurement result in the first MAC CE, and the second position is adjacent to the foremost position;

[0121] The measurement results of at least one second beam, other than the best measurement result, are respectively located at the corresponding third position in the region, which is after the position of the best measurement result;

[0122] The measurement results of at least one second beam are located at the corresponding fourth position in the region, which is after the foremost position.

[0123] The detailed combination and breakdown are described below.

[0124] In some embodiments, the measurement result of the first beam is located at the foremost position in the region carrying the measurement result in the first MAC CE, or at a position after the foremost position (first position).

[0125] The measurement results of the first beam include: the first absolute measurement value, or the first differential measurement value.

[0126] The first differential measurement of the first beam includes: a difference component relative to a first reference measurement, which includes one or more of the following: configured by the network device for the terminal device; agreed by the protocol; or a second absolute measurement of the best measurement result in at least one beam associated with at least one candidate cell.

[0127] In this embodiment, the first position can be any position in the area of ​​the first MAC CE carrying the measurement results, excluding the foremost position, used to place the measurement results. In one example, the terminal device can place the measurement results of the first beam at any position other than the foremost position. Of course, the terminal device can also place the measurement results of the first beam at the corresponding first position according to placement rules such as the size of the measurement results, thereby transmitting the measurement results of the first beam to the network device.

[0128] In this embodiment of the application, the absolute measurement value can be the measurement value obtained by measuring the beam, and the differential measurement value can be the difference or differential component between the absolute measurement value of the beam and the reference measurement value. For different beams, the reference measurement value may be the same or different.

[0129] In this embodiment, the measurement result of the first beam can be carried in the first MAC CE in the form of an absolute value or a differential value. For example, in one case, the measurement result of the first beam can be a first absolute measurement value; in another case, the measurement result of the first beam can be a first differential measurement value. The first differential measurement value can be the difference or differential component between the absolute measurement value of the first beam and a first reference measurement value. The first reference measurement value can be one or more of the following: the absolute measurement value of the beam with the best measurement result (a second absolute measurement value of the best measurement result among at least one beam associated with at least one candidate cell), a measurement value configured by the network device for the terminal device, or a measurement value agreed upon by the protocol.

[0130] In some embodiments, the location of the optimal measurement result in at least one second beam within the region carrying the measurement result in the first MAC CE includes one or more of the following:

[0131] The best measurement result is located at the foremost position in the area carrying the measurement result in the first MAC CE;

[0132] The optimal measurement result is located at the position following the measurement result of the first beam in the region carrying the measurement result in the first MAC CE (second or fourth position), and the measurement result of the first beam is located at the foremost position in the region carrying the measurement result in the first MAC CE.

[0133] In some embodiments, the best measurement result includes a second absolute measurement, or a second differential measurement.

[0134] In some embodiments, the second differential measurement of the optimal measurement result includes: a difference component relative to a second reference measurement, the second reference measurement including one or more of the following: configured by the network device for the terminal device; agreed upon by the protocol; and a first absolute measurement of the first beam.

[0135] In this embodiment, if the measurement result of the first beam is located at the foremost position in the region carrying the measurement result in the first MAC CE, the second position can be the second position in the region carrying the measurement result in the first MAC CE used to place the measurement result of the second beam. It should be noted that the second position is adjacent to the foremost position.

[0136] In this embodiment of the application, if the measurement result of the first beam is located at the foremost position in the region carrying the measurement result in the first MAC CE, the second position can be any position in the region carrying the measurement result in the first MAC CE used to place the measurement result of the second beam.

[0137] In this embodiment of the application, the second position is any position after the first position.

[0138] In this embodiment of the application, the best measurement result among the measurement results of at least one second beam can be the second absolute measurement value, that is, the measurement value obtained by measuring the beam with the best measurement result.

[0139] It should be noted that the optimal measurement result of the second beam can be carried in the first MAC CE in the form of an absolute value or a differential value. For example, in one case, the optimal measurement result can be a second absolute measurement value; in another case, the optimal measurement result can be a second differential measurement value. The second differential measurement value can be the difference or differential component between the absolute measurement value of the optimal beam (corresponding to the optimal measurement result) and a second reference measurement value. This second reference measurement value can be one or more of the following: the absolute measurement value of the first beam (the first absolute measurement value), the measurement value configured by the network device for the terminal device, or the measurement value agreed upon in the protocol.

[0140] In some embodiments, the positions of the measurement results of at least one second beam, other than the best measurement result, in the first MAC CE include: the measurement results of at least one second beam, other than the best measurement result, located at positions (third or fourth positions) after the corresponding foremost position in the region.

[0141] In some embodiments, the measurement results of at least one second beam, other than the best measurement result, include a third differential measurement value.

[0142] In some embodiments, a third differential measurement of other measurement results includes: a difference component relative to a third reference measurement, the third reference measurement including one or more of the following: configured by the network device to the terminal device; agreed by the protocol; a first absolute measurement of the first beam; a second absolute measurement of the best measurement result in at least one beam associated with at least one candidate cell.

[0143] In this embodiment, the measurement results of the second beam can be carried in the MAC CE in the form of absolute values ​​or differential values. For example, in one case, the best measurement result among the measurement results of at least one second beam can be an absolute measurement value (second absolute measurement value), and the measurement results of the other beams in at least one second beam besides the beam corresponding to the best measurement result can be differential measurement values ​​(third differential measurement value); in another case, the measurement results of at least one second beam are all differential measurement values ​​(second differential measurement value and third differential measurement value).

[0144] In this embodiment, the third position can be any position in the area of ​​the first MAC CE that carries the measurement results for placing the measurement results. Here, the third position can be after the foremost position (for example, when the measurement results of the first beam are at the foremost position). Of course, the third position can also be after the position where the best measurement result is located (applicable when the measurement results of the first beam are at the foremost position, or when the best measurement result of the best beam is at the foremost position).

[0145] It should be noted that the third position of the measurement result in the region carrying the measurement result in the first MAC CE differs for different second beams (excluding the optimal beam). For example, if at least one second beam (excluding the optimal beam) includes second beam A and second beam B, the third position of the measurement result of second beam A is the third position in the region carrying the measurement result in the first MAC CE, and the third position of the measurement result of second beam B is the fourth position in the region carrying the measurement result in the first MAC CE. It should be noted that the description of the Mth position of subsequent second beams and the Mth position of third beams is similar.

[0146] In this embodiment, the fourth position (containing at least one second beam of the optimal beam) can be any position within the region of the first MAC CE that carries the measurement results, used to place the measurement results. Here, the fourth position can be after the foremost position; of course, the third position can also be after the position where the measurement results of the first beam are located.

[0147] In general, the optimal measurement result can be located at the foremost position in the region carrying the measurement result, or, if the measurement result of the first beam is located at the foremost position in the region carrying the measurement result in the first MAC CE, then the measurement result of the first beam can be located after the position of the measurement result of the first beam. The measurement results of at least one second beam, other than the optimal measurement result, can be located at any position different from the position of the optimal measurement result, after the corresponding foremost position in the region carrying the measurement result.

[0148] In this embodiment, the foremost position can be the first position in the area of ​​the MAC CE carrying the measurement results used to place the measurement results of the first beam. The terminal device can place the measurement results of the first beam in the foremost position in the area of ​​the first MAC CE carrying the measurement results to transmit the measurement results of the first beam to the network device. Of course, the terminal device can also place the best measurement result from at least one second beam in the foremost position in the area of ​​the first MAC CE carrying the measurement results; this application does not impose specific limitations on this.

[0149] In some embodiments, the measurement results contained in the region carrying the measurement results in the first MAC CE may include the measurement results of the first beam. In this case, the measurement results of the first beam may be located at the foremost position in the region carrying the measurement results in the first MAC CE.

[0150] In some embodiments, the measurement results contained in the region carrying the measurement results in the first MAC CE may include the measurement results of the first beam and the optimal measurement result. In this case, the measurement result of the first beam may be located at the foremost position (or the first position) in the region carrying the measurement results in the first MAC CE, and the optimal measurement result may be located at the second position (or the foremost position) in the region carrying the measurement results in the first MAC CE; it should be noted that the first position and the second position are the same position.

[0151] In one example, the first beam can be beam 1, and at least one second beam includes beam 2, wherein the beam with the best measurement result in the measurement results corresponding to beam 1 and beam 2 is beam 2. In this case, the measurement result of beam 1 is located at the foremost (or second) position in the area carrying the measurement result in the MAC CE, and the best measurement result of beam 2 can be located at the second (or foremost) position in the area carrying the measurement result in the MAC CE.

[0152] In some embodiments, the measurement results contained in the region carrying the measurement results in the first MAC CE may include the measurement results of the first beam and the remaining measurement results. In this case, the measurement results of the first beam may be located at the foremost position in the region carrying the measurement results in the first MAC CE, and the remaining measurement results may be located at the third position after the foremost position in the region carrying the measurement results in the first MAC CE.

[0153] In some embodiments, the measurement results contained in the region carrying the measurement results in the first MAC CE may include the measurement results of the first beam, the optimal measurement results, and the remaining measurement results. In this case, the locations of the measurement results of the first beam, the optimal measurement results, and the remaining measurement results may include the following:

[0154] In some embodiments, the measurement result of the first beam is located at the foremost position in the region carrying the measurement result in the first MAC CE, the best measurement result of at least one second beam is located at a second position in the region carrying the measurement result in the first MAC CE adjacent to the foremost position, and the measurement results of the remaining beams in at least one second beam, excluding the beam corresponding to the best measurement result, are respectively located at a third position in the region carrying the measurement result in the first MAC CE after the second position.

[0155] In one example, the first beam can be beam 1, and at least one second beam includes beam 2 and beam 3. Among the measurement results corresponding to beam 1, beam 2 and beam 3, the best measurement result is beam 2. At this time, the measurement result of beam 1 is located at the foremost position in the area carrying the measurement result in the MAC CE. The best measurement result of beam 2 can be located at the second position in the area carrying the measurement result in the MAC CE, and the measurement result of beam 3 can be located at the third position in the area carrying the measurement result in the MAC CE.

[0156] In some embodiments, the best measurement result of at least one second beam is located at the foremost position in the region carrying the measurement result in the first MAC CE, the measurement result of the first beam is located at a first position after the foremost position in the region carrying the measurement result in the first MAC CE, and the measurement results of the remaining beams in at least one second beam, excluding the beam corresponding to the best measurement result, are respectively located at a third position after the foremost position in the region carrying the measurement result in the first MAC CE.

[0157] In one example, the first beam can be beam 1, and at least one second beam includes beam 2 and beam 3. Among the measurement results corresponding to beam 1, beam 2 and beam 3, the best measurement result is beam 2. In this case, the best measurement result of beam 2 is located at the foremost position in the area carrying the measurement result in the MAC CE. The measurement result of beam 1 (or beam 3) can be located at the second position in the area carrying the measurement result in the MAC CE, and the measurement result of beam 3 (or beam 1) can be located at the third position in the area carrying the measurement result in the MAC CE.

[0158] In some embodiments, the measurement result of the first beam is located at the foremost position in the region carrying the measurement result in the first MAC CE, and the measurement result of at least one second beam is located at the fourth position corresponding to the foremost position in the region carrying the measurement result in the first MAC CE.

[0159] In one example, the first beam can be beam 1, and at least one second beam includes beam 2 and beam 3. Among the measurement results corresponding to beam 1, beam 2 and beam 3, the best measurement result is beam 2. In this case, the measurement result of beam 1 is located at the foremost position in the area carrying the measurement result in the MAC CE, the measurement result of beam 2 (or beam 3) can be located at the second position in the area carrying the measurement result in the MAC CE, and the measurement result of beam 3 (or beam 2) can be located at the third position in the area carrying the measurement result in the MAC CE.

[0160] As described above, the measurement results of the first beam and at least one second beam are placed in the area of ​​the first MAC CE that carries the measurement results according to different rules. The terminal device uses the MAC CE to prioritize reporting key information to the network device, namely the measurement results of the beam that meets the measurement event and the measurement results of other beams, so that the network can determine whether to trigger a handover or reselection, thereby responding to changes in network status in a timely manner.

[0161] In this embodiment, the measurement results of at least one second beam, other than the best measurement result, can be third differential measurement values. The third differential measurement value can be the difference or differential component between the absolute measurement value of each second beam (excluding the beam with the best measurement result) and a third reference measurement value. The third reference measurement value can be one or more of the following: the absolute measurement value of the first beam, the absolute measurement value of the best beam with the best measurement result, the measurement value configured by the network device for the terminal device, or a measurement value agreed upon by the protocol.

[0162] It should be noted that the third differential measurement values ​​corresponding to different second beams (at least one second beam excluding the best measurement result) may be different or the same. For example, if at least one second beam includes second beam A and second beam B, and the absolute measurement values ​​corresponding to second beam A and second beam B are different, then the third differential measurement value of second beam A is different from the third differential measurement value corresponding to second beam B; conversely, if the absolute measurement values ​​corresponding to second beam A and second beam B are the same, then the third differential measurement value of second beam A is the same as the third differential measurement value corresponding to second beam B. It should be noted that subsequent differential measurement values ​​are similar.

[0163] The second differential measurement value can be the difference or differential component of the absolute measurement value (second absolute measurement value) of the best beam in at least one second beam relative to the second reference measurement value. The second reference measurement value can be the absolute measurement value (first absolute measurement value) of the first beam, the measurement value configured by the network device for the terminal device, or the measurement value agreed upon by the protocol.

[0164] In some embodiments, the measurement results contained in the region carrying the measurement results in the first MAC CE may include the measurement results of the first beam. The measurement results of the first beam may be located at the foremost position in the region carrying the measurement results in the first MAC CE. The measurement results of the first beam may be a first absolute measurement value or a first differential measurement value.

[0165] It is understandable that when the measurement result of the first beam is the first absolute measurement value, the first absolute measurement value of the first beam can be located at the foremost position in the area carrying the measurement result in the first MAC CE. At this time, the terminal device can report the first information carrying the first absolute measurement value of the first beam to the network device via the first MAC CE. The network device does not need to convert the measurement result of the first beam, thus it can directly obtain the network status of the first beam and respond to changes in the network status in a timely manner.

[0166] It is understandable that when the measurement result of the first beam is a first differential measurement value, the first differential measurement value of the first beam can be located at the foremost position in the area carrying the measurement result in the first MAC CE, or at the first position in the area carrying the measurement result in the first MAC CE. In this case, the terminal device can report the first information carrying the first differential measurement value of the first beam to the network device through the MAC CE. Because the measurement result of the first beam is reported in differential form, resource utilization and MAC CE overhead are reduced.

[0167] In some embodiments, the measurement results contained in the region carrying the measurement results in the first MAC CE may include the measurement results of the first beam and the optimal measurement result. In this case, the measurement result of the first beam may be located at the foremost position (or the first position) in the region carrying the measurement results in the first MAC CE, and the measurement result of the first beam may be a first absolute measurement value; the optimal measurement result may be located at a second position (or the foremost position) in the region carrying the measurement results in the first MAC CE, and the optimal measurement result may be a second absolute measurement value or a second differential measurement value.

[0168] It should be noted that the first position and the second position are the same position. Alternatively, the measurement result of the first beam can be located at the foremost position in the area carrying the measurement result in the first MAC CE, and the measurement result of the first beam can be the first differential measurement value; the optimal measurement result can be located at the second position in the area carrying the measurement result in the first MAC CE, and the optimal measurement result can be the second differential measurement value.

[0169] In some embodiments, the measurement results contained in the area carrying the measurement results within the first MAC CE may include the measurement results of the first beam, the optimal measurement results, and other measurement results. In this case, the location and form of the measurement results of the first beam, the optimal measurement results, and other measurement results may include the following:

[0170] In some embodiments, the measurement result of the first beam is located at the foremost position in the region carrying the measurement result in the first MAC CE, and the measurement result of the first beam can be a first absolute measurement value. The best measurement result among the measurement results of at least one second beam is located at a second position in the region carrying the measurement result in the first MAC CE, and the best measurement result can be a second absolute measurement value. The measurement results of the other beams in at least one second beam, excluding the beam corresponding to the best measurement result, are respectively located at a third position in the region carrying the measurement result in the first MAC CE, corresponding to the foremost position and the second position, and the measurement results of the other beams are third differential measurement values.

[0171] In some embodiments, the best measurement result among the measurement results of at least one second beam is located at the foremost position in the region carrying the measurement results in the first MAC CE, and this best measurement result can be a second absolute measurement value. The measurement results of the first beam, and the measurement results of the other beams in at least one second beam other than the beam corresponding to the best measurement result, are respectively located at positions after the foremost position in the region carrying the measurement results in the first MAC CE. The measurement result of the first beam can be a first differential measurement value, and the measurement results of the other beams can be third differential measurement values.

[0172] In some embodiments, the measurement result of the first beam is located at the foremost position in the region carrying the measurement result in the first MAC CE, and the measurement result of the first beam can be a first absolute measurement value. The measurement results of at least one second beam (including the best measurement result) are respectively located at the fourth position after the foremost position in the region carrying the measurement result in the first MAC CE, the best measurement result can be a second differential measurement value, and the measurement results of the other beams are third differential measurement values.

[0173] In some embodiments, the measurement result of the first beam is located at the foremost position in the region carrying the measurement result in the first MAC CE, and the measurement result of the first beam can be a first differential measurement value. The measurement results of at least one second beam (including the best measurement result) are respectively located at the fourth position after the foremost position in the region carrying the measurement result in the first MAC CE, the best measurement result can be a second differential measurement value, and the measurement results of the other second beams are third differential measurement values.

[0174] It should be noted that in the above scheme, the measurement results of the beams placed in the form of differential values ​​or differential components can be placed in the area carrying the measurement results of the MAC CE, either in order of differential value or differential component magnitude or not. If the differential value or differential component magnitude is arranged in descending order, it ensures that the terminal device can use the MAC CE to prioritize reporting key information to the network device, such as the measurement results of the beams that meet the measurement event and the beams with higher measurement results. This allows the network device to determine whether to trigger a handover or reselection based on the reported beam measurement results, thereby responding promptly to changes in network status and improving the accuracy of communication.

[0175] In one example, the measurement result of the first beam is located at the foremost position in the region carrying the measurement result within the MAC CE, and this measurement result can be a first absolute measurement value. The optimal measurement result is located at a second position in the region carrying the measurement result within the MAC CE, and this optimal measurement result can be a second absolute measurement value. The measurement results of at least one second beam, excluding the beam corresponding to the optimal measurement result, are located at a third position in the region carrying the measurement result within the MAC CE, corresponding to the foremost and second positions, respectively, and the measurement results of this remaining beam are third differential measurements. In this case, the third reference measurement value corresponding to the third differential measurement value can be a second absolute measurement value.

[0176] It can be understood that the third differential measurement value can be the difference or differential component between the absolute measurement value of the other beams and the second absolute measurement value. In this way, the terminal device can report the first information, carrying the measurement value of the first beam, the measurement value of the best measurement result, and the differential measurement values ​​of the other beams, to the network device through MAC CE. Since the reporting is in differential form, resource utilization is reduced and the overhead of MAC CE is reduced.

[0177] In another example, the optimal measurement result is located at the foremost position in the region carrying the measurement result within the MAC CE, and this optimal measurement result can be a second absolute measurement value. The measurement results of the first beam and the measurement results of at least one second beam, excluding the beam corresponding to the optimal measurement result, are respectively located at positions after the foremost position in the region carrying the measurement result within the MAC CE. The measurement result of the first beam can be a first differential measurement value, and the measurement results of the remaining beams can be third differential measurement values. In this case, the reference measurement values ​​corresponding to the first and second differential measurement values ​​are both second absolute measurement values.

[0178] It can be understood that the first differential measurement value and the second differential measurement value can be the difference or differential component of the beam's measurement value relative to the second absolute measurement value. In this way, the terminal device can report the first information, carrying the measurement value of the beam with the best measurement result, as well as the differential measurement values ​​of other beams (including the first beam), to the network device through MAC CE. Because the reporting is in differential form, resource utilization is reduced and the overhead of MAC CE is reduced.

[0179] In another example, the measurement result of the first beam is located at the foremost position in the region carrying the measurement result in the MAC CE, and the measurement result of the first beam can be a first absolute measurement value. The measurement results of at least one second beam are located at the fourth position after the foremost position in the region carrying the measurement result in the MAC CE, and the measurement result of at least one second beam is a third differential measurement value. In this case, the reference measurement value corresponding to the third differential measurement value can be the first absolute measurement value.

[0180] Understandably, the third differential measurement value can be the difference or differential component of the measurement value of at least one second beam relative to the first absolute measurement value. In this way, the terminal device can report the first information, carrying the measurement value of the first beam and the differential measurement value of at least one second beam, to the network device via MAC CE. Since the measurement results of most beams are reported in differential form, resource utilization and MAC CE overhead are reduced.

[0181] In another example, the measurement result of the first beam is located at the foremost position in the area carrying the measurement result in the MAC CE, and the measurement result of the first beam can be a first differential measurement value. The measurement results of at least one second beam are located at the fourth position after the foremost position in the area carrying the measurement result in the MAC CE, and the measurement result of at least one second beam is a third differential measurement value. In this case, the reference measurement values ​​corresponding to the first and third differential measurement values ​​are both configured by the network device for the terminal device, or are reference measurement values ​​agreed upon by the protocol.

[0182] Understandably, the first differential measurement value can be the difference or differential component of the measurement value of the first beam relative to a reference measurement value, and the third differential measurement value can be the difference or differential component of the measurement value of at least one second beam relative to the same reference measurement value, which can be configured by the network or agreed upon by the protocol. In this way, the terminal device can report the first information carrying the differential measurement values ​​of the first beam and at least one second beam to the network device via MAC CE. Since the measurement results of all beams are reported in differential form, resource utilization and MAC CE overhead are reduced.

[0183] In some embodiments, the measurement results of the beams included in the first information are the measurement results of a portion of all beams, all beams including at least one beam associated with at least one candidate cell, wherein the measurement results of the portion of the beams are respectively located at positions corresponding to the foremost position to the termination position in the region carrying the measurement results in the first MAC CE.

[0184] The measurement result of the first beam is located in the first MAC CE between the foremost position and the termination position, and includes both the foremost position and the termination position.

[0185] In some embodiments, the termination location includes one or more of the following:

[0186] The location of the measurement results for the first beam;

[0187] The position offset by the first byte relative to the first position.

[0188] In some embodiments, the first byte size is determined based on the currently available uplink resources configured in the network device.

[0189] In this embodiment of the application, the termination position can be the location of the measurement result of the first beam in the region carrying the measurement result in the first MAC CE. Of course, the termination position can also be a position offset by the first byte size relative to the third position, i.e. the foremost position.

[0190] In this embodiment of the application, the first byte size can be the byte size of the first MAC CE occupied by the measurement results of all beams, or the first byte size can be the byte size of the first MAC CE occupied by the measurement results of some beams among all beams.

[0191] It should be noted that the size of the first byte can be determined based on the currently available uplink resources configured in the network device. If the currently available uplink resources configured in the network device are sufficient to accommodate / transmit the MAC CE carrying the measurement results of all beams, then the size of the first byte can be the size of the MAC CE occupied by the measurement results of all beams. If the currently available uplink resources configured in the network device are insufficient to accommodate / transmit the MAC CE carrying the measurement results of all beams, the size of the MAC CE that the currently available uplink resources configured in the network device can accommodate / transmit is determined. Based on the size of the MAC CE, the size of the bytes occupied by the area carrying the measurement results in the MAC CE is determined. In this case, the size of the first byte can be the size of the bytes occupied by the area carrying the measurement results in the MAC CE.

[0192] In this embodiment, the position of the measurement result of the first beam in the region carrying the measurement result in the MAC CE, located between the foremost position and the end position, includes the following three methods: First, the position of the measurement result of the first beam in the region carrying the measurement result in the MAC CE is the foremost position; second, the position of the measurement result of the first beam in the region carrying the measurement result in the MAC CE is the end position; third, the position of the measurement result of the first beam in the region carrying the measurement result in the MAC CE is any position between the foremost position and the end position. This application does not impose specific restrictions on this.

[0193] In this embodiment of the application, the terminal device can use MAC CE to prioritize reporting key information to the network device, such as the measurement results of the beam that meets the measurement event and the measurement results of other beams. The network device determines whether to trigger a handover or reselection based on the reported measurement results of the first beam and the measurement results of other beams, so as to respond to changes in network status in a timely manner.

[0194] In some embodiments, the terminal device sending the first information further includes: sending the first information if a first condition is not met; wherein the first condition includes: the currently available uplink resources accommodate or transmit the measurement results of all beams, and all beams include at least one beam associated with at least one candidate cell.

[0195] In one embodiment of this application, when the network device allocates sufficient uplink resources to the terminal device to accommodate or transmit the measurement results of all beams, the first condition is met. At this time, the terminal device can send first information carrying the measurement results of all beams, which is transmitted via a first MAC CE. Thus, the terminal device can use the MAC CE to report the measurement results of all beams to the network device. Based on the reported measurement results of all beams, the network device determines whether to trigger a handover or reselection, thereby responding promptly to changes in network status.

[0196] In another embodiment of this application, when the currently available uplink resources configured by the network device for the terminal device are insufficient to accommodate or transmit the measurement results of all beams, indicating that the first condition is not met, the terminal device can send first information including the measurement results of the first beam that satisfies the triggering event. This first information is carried in the first MAC CE and transmitted. In this way, the terminal device can use the MAC CE to report key information, namely the measurement results of the beams that satisfy the measurement event, to the network device, improving transmission rate while saving resources. Simultaneously, the terminal device reports the first information to the network device, enabling the network device to determine whether to trigger a handover or reselection based on the reported measurement results of the first beam, thereby responding promptly to changes in network status.

[0197] In another embodiment of this application, based on the foregoing embodiments and referring to FIG4, after the terminal device sends the first information in step S310, the following steps may also be performed:

[0198] S410, the terminal device sends second information, and correspondingly, the network device receives the second information; wherein, the second information is carried in the second MAC CE, and the second information includes the measurement results of at least one third beam, the third beam being a beam other than the first beam and the second beam among at least one beam associated with at least one candidate cell.

[0199] In this embodiment, under MAC CE truncation, the aforementioned at least one second beam is a portion of the at least one beam associated with at least one candidate cell, excluding the first beam. At this time, at least one third beam also exists associated with at least one candidate cell. If the third beam is a portion of the at least one beam associated with at least one candidate cell, excluding the first and second beams, information containing the measurement results of the remaining beams can still be sent to the network device. If the at least one third beam is all the beams of the portion of the at least one beam associated with at least one candidate cell, excluding the first and second beams, no further information needs to be sent to the network device.

[0200] In this embodiment, the second information being carried in the second MAC CE can be understood as the second MAC CE carrying the second information. It should be noted that the first MAC CE and the second MAC CE can be the same or different. For example, the way the first MAC CE and the second MAC CE carry the measurement results and / or the rules for carrying the measurement results can be the same or different.

[0201] In this embodiment, after sending the first information, including the measurement results of the first beam that triggered the event, the terminal device can continue to send the second information. In this way, the terminal device will carry the first information, such as the key measurement results, carrying the measurement results of the first beam, and report the information once on the first MAC CE. Then, it will carry the second information, including the measurement results of the remaining beams, on the second MAC CE and report the information a second time. In this way, the terminal device can report the measurement results of all beams associated with the candidate cells to the network device. The network device can determine whether to trigger a handover or reselection based on the measurement results of all beams reported twice, thereby responding to changes in network status in a timely manner.

[0202] In some embodiments, the location of the first or best measurement result in the measurement results of at least one third beam within the second MAC CE includes one or more of the following:

[0203] The first measurement result in at least one third beam is located at the foremost position in the region;

[0204] The best measurement result among the measurements of at least one third beam is located after the foremost position in the region;

[0205] The best measurement result among the measurements of at least one third beam is located at the foremost position in the region;

[0206] The first measurement result in at least one third beam is located after the foremost position in the region.

[0207] In some embodiments, the remaining measurement results in at least one third beam, excluding the first or best measurement result, are located in the second MAC CE at the following positions:

[0208] The remaining measurement results from at least one third beam, excluding the first or best measurement result, are located at positions following the foremost position in the region (sixth position).

[0209] In this embodiment, at least one third beam can be placed directly in the region of the second MAC CE carrying the measurement results, according to the order or position (e.g., the fifth position) before the measurement results are truncated.

[0210] In this embodiment of the application, the fifth position is any one or more positions in the area of ​​the second MAC CE that carries the measurement results.

[0211] In this embodiment, the measurement results of at least one third beam are respectively located at the fifth position in the region carrying the measurement results in the second MAC CE. It should be noted that the measurement results of at least one third beam can be placed in the corresponding fifth position in the region carrying the measurement results in the second MAC CE, either in order of magnitude or not.

[0212] In one example, at least one beam associated with at least one candidate cell includes beam 1, beam 2, beam 3, beam 4, beam 5, and beam 6. After the measurement results of beam 1, beam 2, and beam 3 are sent to the network device in the first information, the remaining beam, i.e., at least one third beam, includes beam 4, beam 5, and beam 6. The measurement result of beam 4 (or beam 5, or beam 6) is located at the foremost position in the area carrying the measurement results in the MAC CE. The optimal measurement result of beam 5 (or beam 4, or beam 6) can be located at the second position in the area carrying the measurement results in the MAC CE. The measurement result of beam 6 (or beam 5, or beam 4) can be located at the third position in the area carrying the measurement results in the MAC CE.

[0213] In this embodiment, the sixth position is any position in the region of the second MAC CE that carries the measurement results, excluding the foremost position, including but not limited to the termination position, and any position between the foremost position and the termination position.

[0214] In one embodiment of this application, the first measurement result of at least one third beam is located at the foremost position in the region carrying the measurement results in the second MAC CE, and the measurement results of the remaining beams in at least one third beam, excluding the beam corresponding to the first measurement result, are respectively located at the sixth position after the foremost position in the region carrying the measurement results in the second MAC CE.

[0215] In one example, at least one third beam includes beams 4, 5, and 6, wherein the first measurement result in the measurement results corresponding to beams 4, 5, and 6 is beam 4. In this case, the measurement result of beam 4 is located at the foremost position in the region carrying the measurement results within the MAC CE; the optimal measurement result of beam 5 (or beam 6) can be located at the second position in the region carrying the measurement results within the MAC CE; and the measurement result of beam 6 (or beam 5) can be located at the third position in the region carrying the measurement results within the MAC CE.

[0216] In another embodiment of this application, the best measurement result among the measurement results of at least one third beam is located at the foremost position in the region carrying the measurement results in the second MAC CE, and the measurement results of the remaining beams in at least one third beam, excluding the beam corresponding to the best measurement result, are respectively located at the sixth position after the foremost position in the region carrying the measurement results in the second MAC CE.

[0217] In one example, at least one third beam includes beams 4, 5, and 6, wherein the best measurement result among the measurement results corresponding to beams 4, 5, and 6 is beam 5. In this case, the measurement result of beam 5 is located at the foremost position in the region carrying the measurement result within the MAC CE, the measurement result of beam 4 (or beam 6) can be located at the second position in the region carrying the measurement result within the MAC CE, and the measurement result of beam 6 (or beam 4) can be located at the third position in the region carrying the measurement result within the MAC CE.

[0218] In another embodiment of this application, the first measurement result of at least one third beam is located at the foremost position in the region carrying the measurement results in the second MAC CE, and the measurement results of the remaining beams in at least one third beam, excluding the beam corresponding to the first measurement result, are respectively located at the sixth position after the foremost position in the region carrying the measurement results in the second MAC CE.

[0219] In one example, at least one third beam includes beams 4, 5, and 6, wherein the first measurement result in the measurement results corresponding to beams 4, 5, and 6 is beam 5. In this case, the measurement result of beam 5 is located at the foremost position in the region carrying the measurement results within the MAC CE; the measurement result of beam 4 (or beam 6) can be located at the second position in the region carrying the measurement results within the MAC CE; and the measurement result of beam 6 (or beam 4) can be located at the third position in the region carrying the measurement results within the MAC CE.

[0220] In some embodiments, the first measurement result includes a third absolute measurement, or a fourth differential measurement;

[0221] The best measurement result among the measurements of at least one third beam includes a fourth absolute measurement, or a fifth differential measurement.

[0222] In some embodiments, the fourth differential measurement of the first measurement result includes: a difference relative to a fourth reference measurement, which includes one or more of the following: configured by the network device to the terminal device; agreed by the protocol; an absolute measurement in the previous MAC CE carrying the measurement result; or a fourth absolute measurement of the beam with the best measurement result in at least one third beam (in the case that the best measurement result is in the foremost position).

[0223] In some embodiments, the fifth differential measurement of the best measurement result includes: a difference relative to a fifth reference measurement, which includes one or more of the following: configured by the network device to the terminal device; agreed by the protocol; an absolute measurement in the previous MAC CE carrying the measurement result; or a third absolute measurement of the beam of the first measurement result in at least one third beam (in the case where the first measurement result is in the foremost position).

[0224] In some embodiments, the remaining measurement results of at least one third beam, excluding the first or best measurement result, include a sixth differential measurement value.

[0225] In some embodiments, the sixth differential measurement of the remaining measurement results includes: a difference component relative to a sixth reference measurement, which includes one or more of the following: configured by the network device to the terminal device; agreed by the protocol; the absolute measurement in the previous MAC CE carrying the measurement results; the fourth absolute measurement of the best measurement result in at least one third beam (if the best measurement result is in the foremost position); and the third absolute measurement of the first measurement result in at least one third beam (if the first measurement result is in the foremost position).

[0226] In this embodiment, the measurement results of the third beam can be carried in the MAC CE in the form of absolute values ​​or differential values. For example, in one case, the first or best measurement result among all the measurement results of the third beams can be an absolute measurement value, and the measurement results of the other beams besides the beam corresponding to the first or best measurement result can be differential measurement values; in another case, all the measurement results of the third beams are differential measurement values; and in yet another case, all the measurement results of the third beams are absolute measurement values.

[0227] In the embodiments of this application, the remaining measurement results in the measurement results of at least one third beam can be understood as the measurement results of the remaining beams in at least one third beam, excluding the beam corresponding to the first measurement result or the best measurement result.

[0228] In this embodiment, the measurement results of at least one third beam are respectively located at the fifth position corresponding to the area carrying the measurement results in the second MAC CE; wherein, the measurement results of at least one third beam can all be third absolute measurement values. Thus, the terminal device can report the second information carrying the third absolute measurement values ​​of all third beams to the network device via the MAC CE. The network device does not need to convert the measurement results of the third beams, thereby directly obtaining the network status of the third beams and responding promptly to changes in the network status.

[0229] In this embodiment of the application, the measurement results of at least one third beam are respectively located at the fifth position corresponding to the region carrying the measurement results in the second MAC CE; wherein, the measurement results of at least one third beam can be differential measurement values.

[0230] In this embodiment, the first measurement result of at least one third beam is located at the foremost position in the region carrying the measurement results in the second MAC CE, and the first measurement result can be a third absolute measurement value. The measurement results of the remaining beams in at least one third beam, excluding the beam corresponding to the first measurement result, are respectively located at the sixth position after the foremost position in the region carrying the measurement results in the second MAC CE; wherein, the measurement results of the remaining beams in at least one third beam, excluding the beam corresponding to the first measurement result, are sixth differential measurement values.

[0231] In this embodiment, the best measurement result among the measurement results of at least one third beam is located at the foremost position in the region carrying the measurement results in the second MAC CE, and the best measurement result is the fourth absolute measurement value. The measurement results of the remaining beams in at least one third beam, excluding the beam corresponding to the best measurement result, are respectively located at the sixth position after the foremost position in the region carrying the measurement results in the second MAC CE; wherein, the measurement results of the remaining beams in at least one third beam, excluding the beam corresponding to the best measurement result, are the sixth differential measurement values.

[0232] In this embodiment, the fifth absolute measurement value can be the absolute measurement value in the previous MAC CE carrying the measurement result. It should be noted that the absolute measurement value in the previous MAC CE carrying the measurement result can include one or more; if it includes one, the absolute measurement value in the previous MAC CE carrying the measurement result can be the fifth absolute measurement value. If it includes multiple values, the beam identifier corresponding to the fifth absolute measurement value can be indicated in the MAC CE carrying the second information.

[0233] In this embodiment, the fourth differential measurement value may be the difference between the first measurement result and the fifth absolute measurement value in the previous MAC CE carrying the measurement result.

[0234] In this embodiment, the fifth differential measurement value can be the difference between the best measurement result and the fifth absolute measurement value in the previous MAC CE carrying the measurement result.

[0235] In one example, the measurement results of at least one third beam are located at the fifth position corresponding to the area carrying the measurement results in the second MAC CE, and the measurement results of at least one third beam can all be third absolute measurement values. Thus, the terminal device can report the second information carrying the third absolute measurement values ​​of all third beams to the network device via the MAC CE. The network device does not need to convert the measurement results of the third beams, thereby directly obtaining the network status of the third beams and responding promptly to changes in the network status.

[0236] In another example, the measurement results of at least one third beam are respectively located at the fifth position corresponding to the area carrying the measurement results in the second MAC CE, and the measurement results of at least one third beam can all be differential measurement values. In this case, the reference measurement value corresponding to the differential measurement value can be the differential component of the seventh absolute measurement value in the previous MAC CE carrying the measurement results, the value configured by the network device for the terminal device, or the value agreed upon by the protocol. The fourth reference measurement value of the first measurement result relative to the fourth reference measurement value can also include: the fourth absolute measurement value of the beam with the best measurement result among at least one third beam. The fifth reference measurement value of the best measurement result relative to the fifth reference measurement value can also include: the third absolute measurement value of the beam with the first measurement result among at least one third beam. The sixth reference measurement value of the remaining measurement results in at least one third beam, excluding the first measurement result or the best measurement result, relative to the sixth reference measurement value can also include: the fourth absolute measurement value of the best measurement result among at least one third beam (when the best measurement result is in the foremost position); and the third absolute measurement value of the first measurement result among at least one third beam (when the first measurement result is in the foremost position).

[0237] Understandably, differential measurements can be the difference or differential component between the absolute measurement of at least one third beam and its respective reference measurement. Thus, the terminal device can report second information carrying differential measurements of at least one third beam to the network device via MAC CE. Because the reporting is in differential form, resource utilization and MAC CE overhead are reduced.

[0238] In another example, the first measurement result of at least one third beam is located at the foremost position in the region carrying the measurement results in the second MAC CE, and this first measurement result can be a third absolute measurement value. The measurement results of the remaining beams in at least one third beam, excluding the beam corresponding to the first measurement result, are respectively located at the sixth position after the foremost position in the region carrying the measurement results in the second MAC CE, and the measurement results of the remaining beams can be sixth differential measurements. In this case, the reference measurement value corresponding to the sixth differential measurement value can be a third absolute measurement value.

[0239] Understandably, the sixth differential measurement value can be the difference or differential component between the absolute measurement value of at least one third beam and the third absolute measurement value. Thus, the terminal device can report second information carrying the absolute measurement value of the first third beam and the differential measurement values ​​of the remaining third beams to the network device via MAC CE. Since most beams are reported in differential form, resource utilization is reduced, and the overhead of MAC CE is decreased.

[0240] In another example, the best measurement result among the measurements of at least one third beam is located at the foremost position in the region carrying the measurement results in the second MAC CE, and the best measurement result is the fifth absolute measurement value. The measurement results of the remaining beams in at least one third beam, excluding the beam corresponding to the best measurement result, are respectively located at the sixth position after the foremost position in the region carrying the measurement results in the second MAC CE, and the measurement results of the remaining beams can be the sixth differential measurement value. In this case, the reference measurement value corresponding to the sixth differential measurement value can be the fourth absolute measurement value.

[0241] Understandably, the sixth differential measurement value can also be the difference or differential component between the absolute measurement value of at least one third beam and the fourth absolute measurement value. In this way, the terminal device can report the second information, carrying the absolute measurement value of the third beam with the best measurement result and the differential measurement values ​​of the remaining third beams, to the network device via MAC CE. Since most of the reporting is in differential form, resource utilization and MAC CE overhead are reduced. Simultaneously, by placing the measurement result of the third beam with the best result first, the network device can respond promptly to changes in network status based on the best measurement result.

[0242] In this embodiment of the application, the fact that the second MAC CE carries measurement results in the same way as the first MAC CE can be understood as follows: the type of measurement result (i.e., absolute measurement value or differential measurement value) of at least one third beam included in the second information in the area where the measurement result is carried in the second MAC CE is the same as the type of measurement result of the first beam that satisfies the trigger event included in the first information in the area where the measurement result is carried in the first MAC CE; and / or, the rules for carrying measurement results in the first MAC CE and the second MAC CE are the same.

[0243] In one example, if the measurement results of the first beam in the first information are all first differential measurement values, and the first differential measurement value is a differential component or differential element relative to the first reference measurement value, the first reference measurement value may be the network device configuration or protocol agreement, or the best measurement result among the measurement results of all candidate cell associated beams, then the measurement results of all third beams in the second information are also differential measurement values, and the differential measurement value is a differential value or differential element relative to the same reference measurement value.

[0244] In another example, if the measurement result of the first beam in the first information is an absolute measurement value, then the measurement results of all third beams in the second information can also be absolute measurement values.

[0245] In another example, if the measurement result of the first beam in the first information is an absolute measurement value, and the measurement results of the other beams in the first information can be differential measurement values, and the differential measurement value is a difference component or differential component relative to the absolute measurement value of the first beam, then the measurement results of all third beams in the second information are also differential measurement values, and the differential measurement value is a difference component or differential component relative to the absolute measurement value of the first beam.

[0246] It should be noted that this application is merely illustrative, and the possible implementation methods are not limited to the embodiments exemplified above.

[0247] In some embodiments, where differential measurements exist in the beam measurement results, the differential measurements include positive and negative values, which are indicated by one or more of the following:

[0248] The first indication information is used to indicate the sign of the differential measurement value;

[0249] The preset measurement range is defined as follows: when the differential measurement value falls within the first preset measurement range, the differential measurement value is positive; when the differential measurement value falls within the second preset measurement range, the differential measurement value is negative.

[0250] In this embodiment of the application, the first indication information is used to indicate the sign of the differential measurement value. The first indication information can use one bit to indicate whether the differential measurement value is positive or negative. For example, when this bit is 1, the first indication information can indicate that the differential measurement value is positive; when this bit is 0, the first indication information can indicate that the differential measurement value is negative; and vice versa.

[0251] It should be noted that the first indication information in the measurement results can be an optional parameter or a mandatory parameter.

[0252] In one scenario, when the best measurement result among all beams is an absolute measurement value, and the measurement results of other beams are the difference components relative to the best measurement result, the first indication information in the measurement result can be an optional parameter. If it is not stated that the first indication information in the measurement result is a mandatory parameter, it can be understood as an optional parameter.

[0253] In another scenario, when the first measurement result among all beams is an absolute measurement value, and the measurement results of other beams are the difference components relative to the first measurement result, then the first indication information in the measurement results can be a mandatory parameter. The first measurement result can be an absolute measurement value of the first beam, a reference measurement value configured by the network device or agreed upon by the protocol, or an absolute measurement value in the previous MAC CE carrying the measurement result. It should be noted that if the first indication information in the measurement results is not explicitly stated as an optional parameter, it can be understood as a mandatory parameter.

[0254] In this embodiment, the preset measurement range can be understood as determining multiple values ​​based on the bits occupied by the differential measurement value, and dividing these multiple values ​​into two preset measurement ranges. The values ​​in each preset measurement range represent both the positive and negative sign of the value, as well as its magnitude. For example, dividing multiple values ​​into two preset measurement ranges, such as a first preset measurement range and a second preset measurement range, predefines that all values ​​in the first preset measurement range are positive, and these positive values ​​also represent the magnitude of the value; and all values ​​in the second preset measurement range are negative, and these negative values ​​also represent the magnitude of the value. The differential measurement value of each beam can be determined based on the preset measurement range to which the differential measurement value belongs, i.e., from the first preset measurement range and the second preset measurement range. In other words, if the differential measurement value belongs to the first preset measurement range, the differential measurement value is positive; if the differential measurement value belongs to the second preset measurement range, the differential measurement value is negative.

[0255] For example, based on the number of bits occupied by the differential measurement value (e.g., 4 bits), 16 different values ​​can be represented by different combinations of values, namely 0000, 0001, 0010, 0011, 0100, 0101, 0110, 0111, 1000, 1001, 1010, 1011, 1100, 1101, 1110, and 1111. These 16 different values ​​are divided into a first part and a second part. The first part includes 0000, 0001, 0010, 0011, 0100, 0101, 0110, and 0111, while the second part includes 1000, 1001, 1010, 1011, 1100, 1101, 1110, and 1111. The values ​​in the first part are predefined to be all positive, and the values ​​in the second part are all negative. Then, when using differential measurements, values ​​can be taken from either the first or the second part to represent the difference component.

[0256] It should be noted that when the first measurement result among all beams is an absolute measurement value, and the measurement results of other beams are differential values ​​relative to the first measurement result, the first measurement result can be the measurement result of the first beam, the measurement result configured by the network device or agreed upon by the protocol, or the absolute measurement value in the previous MAC CE carrying the measurement result. In this case, the differential measurement values ​​can be distinguished as positive or negative by definition.

[0257] In some embodiments, the second information is sent based on one or more of the following:

[0258] The state of the measured event is either triggered or non-triggered.

[0259] Whether the network device is enabled or activated to perform subsequent MAC CE;

[0260] Does the network device enable or activate the execution of periodic MAC CE?

[0261] Does the measurement result of the first beam meet the threshold or trigger delay associated with the trigger event?

[0262] Does the first beam trigger a measurement event again?

[0263] In this embodiment, whether the terminal device sends the second information can be based on the state of the measurement event, whether the network device enables or activates the execution of subsequent MAC CE, whether the network device enables or activates the execution of periodic MAC CE, whether the measurement result of the trigger beam meets the threshold or trigger delay associated with the event, and whether the trigger beam triggers another measurement event again.

[0264] In this embodiment, the triggering state can be understood as the measurement event being in a triggered state when the measurement result of the terminal device on the beam carrying the reference signal meets the conditions set by a specific measurement event. For example, in an LTE system, for measurement event A3, when the signal quality of a neighboring cell is higher than the signal quality of the serving cell by a certain offset value, event A3 is triggered. At this time, the terminal device sends a measurement report to the network device, informing the network device that the conditions of event A3 have been met. After receiving the measurement report, the network device may perform handover or other related operations based on this information to optimize communication quality.

[0265] In this embodiment of the application, when the state of the measurement event is the triggered state, the terminal device may continue to send the second information or may not send the second information.

[0266] In this embodiment, a non-triggered state can be understood as the measurement result of the terminal device not meeting the conditions specified by the measurement event, in which case the measurement event is in a non-triggered state. Continuing with the A3 event as an example, if the neighboring cell signal quality never exceeds the serving cell signal quality plus the offset value, then the A3 event remains in a non-triggered state, the terminal device will not send a measurement report related to the A3 event, and the network device will not perform handover or other operations based on this event.

[0267] In this embodiment of the application, when the state of the measurement event is non-triggered, the terminal device may continue to send the second information or may not send the second information.

[0268] In this embodiment of the application, when the terminal device receives an instruction from the network device to enable or activate the execution of subsequent MAC CE, the terminal device may continue to send the second information; when the terminal device receives an instruction from the network device not to enable or activate the execution of subsequent MAC CE, the terminal device may not send the second information.

[0269] In this embodiment of the application, whether the network device enables or activates the execution of subsequent MAC CE can be understood as follows: when the terminal device receives an indication from the network device to enable or activate the execution of subsequent MAC CE, the terminal device can continue to send MAC CE carrying the second information; when the terminal device receives an indication from the network device not to enable or activate the execution of subsequent MAC CE, the terminal device can choose not to send MAC CE carrying the second information.

[0270] In this embodiment of the application, whether the network device enables or activates the execution of periodic MAC CE can be understood as follows: when the terminal device receives an indication message from the network device to enable or activate the execution of periodic MAC CE, the terminal device can send a MAC CE carrying second information according to a predetermined period; when the terminal device receives an indication message from the network device not to enable or activate the execution of periodic MAC CE, the terminal device can choose not to send a MAC CE carrying second information.

[0271] In this embodiment, the event-associated threshold can be a pre-set specific value used to determine whether the beam measurement result has reached a certain standard. Different measurement events correspond to different thresholds.

[0272] In this embodiment of the application, when the measurement result of the first beam reaches or exceeds the event association threshold, it indicates that the conditions of the corresponding event are met. For example, in a beam switching event, if the RSRP measurement value of the neighboring beam exceeds the RSRP of the current serving beam plus a certain offset threshold, a beam switching event may be triggered, instructing the terminal device to switch from the current serving beam to the neighboring beam with better signal quality in order to optimize communication quality.

[0273] In this embodiment of the application, the trigger delay (time to trigger, TTT) can be the time interval from when the measurement result meets the threshold condition to when the corresponding event is actually triggered.

[0274] In this embodiment, when the measurement result of the first beam meets the trigger delay, it indicates that the measurement result of the first beam continuously meets the threshold condition for a period of time before the corresponding event is triggered. In this way, frequent triggering events caused by instantaneous fluctuations of the signal are avoided, and the stability and reliability of the system are improved.

[0275] In this embodiment of the application, whether the first beam triggers a measurement event again can be understood as the measurement result of the first beam meeting the departure condition of the event. At this time, a new beam adjustment is triggered and a new measurement report is generated. At this time, it means that the terminal device may have moved out of the coverage area of ​​the current first beam, and the terminal device needs to re-measure and evaluate the beam associated with the cell.

[0276] In some embodiments, the measurement results include: beam identification of the beam, and / or, the measurement results of the beam.

[0277] In this embodiment of the application, the beam identifier is used to indicate the unique identifier of the beam.

[0278] In this embodiment of the application, the beam measurement result can be beam quality information obtained by measuring the reference signal carried in the beam. The beam measurement result can be an absolute measurement value or a differential measurement value.

[0279] In this embodiment of the application, the parameters used to measure beam quality include, but are not limited to, the reference signal received power (RSRP). For example, beam quality can also be measured by parameters such as reference signal receiving quality (RSRQ), signal-noise ratio (SNR), signal-to-interference plus noise ratio (SINR), channel quality indicator (CQI), received signal strength indicator (RSSI), and received signal quality indicator (RSQI).

[0280] In some embodiments, the measurement results may further include: indication information associated with each of at least one beam, such as indication information on whether a measurement condition / event is met, and further, the indication information includes indication information on whether an entry condition is met, and / or an exit condition is met.

[0281] In some embodiments, the measurement results may further include: beam type indication information for at least one beam, and / or, measurement result type indication information.

[0282] Here, beam type indication information can be used to indicate the beam type, which includes wide beams and narrow beams. Different types of beams cover different areas and / or transmit different signal qualities. By indicating one of the above-mentioned multiple beam types through beam type indication information, measurement results of at least one beam of the same beam type can be obtained.

[0283] In this embodiment of the application, the measurement result types include RSRP, RSRQ, SNR, SINR, CQI, RSSI, and RSQI. One of the above multiple measurement result types can be indicated by the measurement result type indication information to obtain the measurement result of at least one beam of the same measurement result type.

[0284] In some embodiments, beam identification is indicated by one or more of the following:

[0285] Synchronization signal block index;

[0286] Channel State Information - Reference Signal Index;

[0287] Synchronization signal block relative index;

[0288] Channel state information - reference signal relative index.

[0289] In this embodiment of the application, the beam measurement result may include the beam identifier of the beam. Of course, the beam measurement result may also include the beam measurement result.

[0290] In this embodiment of the application, the beam identifier can be identified by the relative index and / or absolute index of the Synchronization Signal Block (SSB) and / or the Channel Status Information Reference Signal (CSI-RS).

[0291] In one example, the Synchronization Signal Block Index (SSB index) is an absolute index, and the identifier or index of the SSB itself is used to indicate the identifier or index of the beam.

[0292] In another example, the Channel State Information Reference Signal Index (CSI-RS index) is an absolute index, and the identifier or index of the CSI-RS itself is used to indicate the identifier or index of the beam.

[0293] Based on this, the target beam can be directly identified using a global index (SSB Index or CSI-RS index) without relying on a relative index or additional mapping rules, which simplifies the complexity of measurement and beam management, and also simplifies cross-band and cross-cell measurement and resource configuration.

[0294] In another example, the synchronization signal block relative index (SSB relative index, SSB RI) is a relative index used to indicate the relative identifier of each SSB in an associated reference signal set. For example, if the reference signal set includes 8 SSBs, then the SSB RIs of these 8 SSBs are 0, 1, 2, 3, 4, 5, 6 and 7 respectively.

[0295] In another example, the Channel State Information-Reference Signal Relative Index (CSI-RS) is a relative index used to indicate the relative identifier of each CSI-RS in an associated reference signal set. For example, if the reference signal set includes 8 CSI-RS, then the CSI-RS RIs of these 8 CSI-RS are 0, 1, 2, 3, 4, 5, 6 and 7, respectively.

[0296] Based on this, using relative indexes (SSB RI or CSI RI) can simplify the configuration and parsing of measurement reporting, while quickly finding the corresponding beam, reducing the time for beam search and switching, thereby improving the real-time performance and stability of communication.

[0297] In some methods, beam identifiers may also include absolute beam indexes, relative beam indexes, logical beam indexes, indexes of antenna ports corresponding to beams, indexes of antenna port groups corresponding to beams, time indexes of downlink synchronization blocks, beam pair link (BPL) information, transmit parameters (Txparameters) corresponding to beams, receive parameters (Rxparameters) corresponding to beams, transmit weights (weight vectors), weight matrices, receive weights corresponding to beams, or their indices, transmit codebooks corresponding to beams, receive codebooks corresponding to beams, or their indices.

[0298] In some embodiments, the length of the beam identifier is related to the number of reference signals in the reference signal set, and the length of the differential measurement is less than the length of the beam identifier.

[0299] In some embodiments, the length of the beam identifier can be indicated by one or more of the following:

[0300] The length of the relative index of the synchronization signal block;

[0301] Channel state information - length of the relative index of the reference signal resource.

[0302] In this embodiment of the application, the length of the beam identifier can be understood as the bit length occupied by the beam identifier. The length of the beam identifier can be indicated by the length of the relative index of the synchronization signal block (SSB RI) or the length of the relative index of the channel state information reference signal (CSI RI).

[0303] In this embodiment, the Reference Signal Set (RS Set) is a collection of reference signals associated with the measurement reporting configuration. The SSB RI and CSI RI can be used to indicate the relative identifier of each SSB in the associated reference signal set. For example, if the reference signal set includes 8 SSBs, then the SSB RIs of these 8 SSBs are 0, 1, 2, 3, 4, 5, 6, and 7, respectively.

[0304] In this embodiment, the length of the beam identifier is related to the number of reference signals in the reference signal set. If the number of reference signals is a first quantity, the length of the beam identifier can be the value obtained by taking the logarithm of the first quantity to the base 2 and then rounding the logarithm up. Where W is the first quantity. For example, if the number of reference signals in the reference signal set is 512, then the length of the beam identifier is 9 bits.

[0305] In this embodiment, the length of the differential measurement value can be understood as the bit length occupied by the differential measurement value, and the length of the differential measurement value is less than the length of the beam identifier. For example, if the beam identifier length is 9 bits, the length of the differential measurement value can be a first value, which can be one or more of 3, 4, 5, 6, and 7. In some embodiments, the lengths of different differential measurement values ​​can be the same or different; unless otherwise specified, it can be understood that the lengths of the differential measurement values ​​are the same.

[0306] In some embodiments, the first information further includes one or more of the following:

[0307] Measurement event identifier;

[0308] Measurement report configuration identifier;

[0309] An identifier for events that meet the conditions;

[0310] The second indication information is used to indicate whether the first object meets the conditions for triggering the event;

[0311] Service area signage;

[0312] Measurement results of at least one beam associated with the serving cell;

[0313] The third indication information is used to indicate whether to execute subsequent remaining / truncated measurement results.

[0314] In this embodiment, the first information includes the beam measurement result satisfying a specific trigger measurement event, and the specific trigger measurement event identifier (event ID). The measurement event identifier can be a unique number or symbol assigned to a specific measurement event. When a terminal device measures wireless signals according to network requirements, it may encounter different situations or meet specific conditions; these are defined as different measurement events. Each event has a corresponding identifier, so the terminal can use the identifier in the measurement report to inform the base station which event occurred.

[0315] In this embodiment of the application, the first information may further include a measurement report configuration identifier, which is used to associate a measurement report with a specific measurement configuration.

[0316] In this embodiment of the application, the use cases for the measurement report configuration identifier can include the following aspects:

[0317] 1) Event-triggered reports: When a terminal device meets specific event conditions, it will generate and send a measurement report based on the measurement report configuration identifier. For example, when the UE detects a decrease in the signal quality of the serving cell, it will generate an event-triggered measurement report based on the measurement report configuration identifier.

[0318] 2) Periodic reports: The terminal device generates measurement reports periodically according to the periodic parameters defined in the measurement report configuration identifier. For example, a periodic measurement report is generated every 20 milliseconds.

[0319] 3) Record measurement reports. The terminal device records measurement reports when specific conditions are met, until it receives an instruction to stop recording.

[0320] In this embodiment, the first information may further include identifiers of satisfied event conditions. These identifiers include identifiers of entry and leaving conditions. An entry condition can be understood as a condition that triggers the reporting of a measurement report, such as being related to neighboring cell signal quality being better than the serving cell or meeting a specific threshold. A leaving condition can be understood as a condition that stops the reporting of measurement reports, typically related to neighboring cell signal quality no longer meeting the entry condition. The purpose of designing a leaving condition is to avoid frequent reporting of measurement reports and reduce signaling overhead.

[0321] In this embodiment of the application, the first information may further include second indication information, which is used to indicate whether each first object meets the triggering condition. The triggering condition may be a condition for triggering an event, a periodic triggering condition, or other triggering conditions.

[0322] Here, the second indication information can use one bit to indicate whether the first object meets the trigger condition. For example, when this bit is 1, the second indication information can indicate that the first object meets the trigger condition; when this bit is 0, the second indication information can indicate that the first object does not meet the trigger condition; and vice versa.

[0323] In some embodiments, the first object includes one or more of a beam, an event, and a MAC CE.

[0324] In one example, taking the first object as a beam, for each beam, if the beam is the first beam, the second indication information for the beam can be 1; if the beam is another beam besides the first beam, the second indication information for the beam can be 0.

[0325] In another example, taking the first object as an event, if the triggering condition corresponding to the event is met, the second indication information for the event can be 1. It should be noted that if an event includes a MAC CE, then the second indication information for the event is equivalent to the second indication information for the MAC CE. In this case, one MAC CE only needs to include one second indication information. If the triggering condition corresponding to the event is not met, the second indication information for the event can be 0.

[0326] In this embodiment of the application, the first information may further include the serving cell identifier, and / or the measurement results of at least one beam associated with the serving cell.

[0327] In this embodiment, the serving cell identifier is used to uniquely identify a cell, which is described by higher layers from the perspective of resource management, mobility management, or service unit. The coverage area of ​​each network-side device can be divided into one or more cells, and the cell can be regarded as being composed of certain frequency domain resources.

[0328] In this embodiment, the serving cell can be associated with one or more beams. The terminal device can measure each beam associated with the serving cell to obtain the measurement results of the beams associated with the serving cell. Here, the measurement results of the beams associated with the serving cell can be absolute measurement values ​​or differential measurement values. If it is a differential measurement value, the differential measurement value can be the difference between the absolute measurement value of the beam and a reference measurement value. The reference measurement value includes, but is not limited to, the absolute measurement value of the beam with the best measurement result, the absolute measurement value of the first beam, the measurement value configured by the network device for the terminal device, or the measurement value agreed upon by the protocol.

[0329] In this embodiment of the application, the first information may further include third indication information, which can be used to indicate whether to report the remaining measurement results. Here, the remaining measurement results can be understood as the measurement results of at least one third beam included in the second information, which are also called the remaining measurement results, or the truncated measurement results.

[0330] Here, the third indication information can use 1 bit to indicate whether to execute the remaining measurement results. For example, when this bit is 1, the third indication information can indicate to execute the remaining measurement results; when this bit is 0, the second indication information can indicate not to execute the remaining measurement results; and vice versa.

[0331] In yet another embodiment of this application, based on the foregoing embodiments and referring to FIG5, the following steps may also be performed before sending the first information in step S310:

[0332] S510: The terminal device receives the reported configuration information, and correspondingly, the network device sends the reported configuration information; wherein the reported configuration information includes one or more of the following:

[0333] Reference measurement value;

[0334] The third indication information is used to indicate the currently available uplink resources;

[0335] The fourth instruction information is used to indicate whether to enable or activate the execution of subsequent MAC CE;

[0336] The fifth instruction information is used to indicate whether to enable or activate the execution of periodic MAC CE.

[0337] In this embodiment of the application, the reported configuration information may include reference measurement values, which may be measurement values ​​configured by the network device for the terminal device. The terminal device may determine the differential value of the beam associated with the candidate cell based on the reference measurement values.

[0338] In this embodiment of the application, the reported configuration information may further include third indication information, which is used to indicate the currently available uplink resources. The currently available uplink resources can be understood as the size of the uplink resources configured by the network device for the terminal device to transmit the MAC CE carrying the first information.

[0339] In this embodiment of the application, the reported configuration information may further include fourth indication information, which is used to indicate whether to enable or activate the execution of subsequent MAC CE. Here, the fourth indication information can use 1 bit to indicate whether to enable or activate the execution of subsequent MAC CE. For example, when this bit is 1, the fourth indication information can indicate that the execution of subsequent MAC CE is enabled or activated; when this bit is 0, the fourth indication information can indicate that the execution of subsequent MAC CE is not enabled or activated; and vice versa.

[0340] In this embodiment of the application, the reported configuration information may further include fifth indication information, which is used to indicate whether to enable or activate the execution of periodic MAC CE. Here, the fifth indication information can use 1 bit to indicate whether to enable or activate the execution of periodic MAC CE. For example, when this bit is 1, the fifth indication information can indicate that the execution of periodic MAC CE is enabled or activated; when this bit is 0, the fifth indication information can indicate that the execution of periodic MAC CE is not enabled or activated; and vice versa.

[0341] It should be noted that the third, fourth, and fifth indication information in the reported configuration information can be optional or mandatory parameters; if it is not stated that the third, fourth, and fifth indication information in the measurement results are optional parameters, it can be understood that the third, fourth, and / or fifth indication information are mandatory parameters.

[0342] The following section, taking the terminal device as UE and the network device as network or base station as an example, elaborates on the beam measurement result reporting method provided in the embodiments of this application.

[0343] In the discussion of the R19 L1 event triggered measurement report, it was agreed to use MAC CE as the reporting format for measurement results. Considering the limited resources of MAC CE, a truncated MAC CE will be used to report part of the measurement results.

[0344] To save on MAC CE overhead, it is agreed to use differential values ​​(such as differential RSRP) to indicate beam measurement results. This requires placing the beam with the highest RSRP result first. On the other hand, when the UE uses truncated MR MAC CE, it is necessary to report more important information, such as the event ID, which has triggered the beam measurement result to be reported.

[0345] So, when the beam with the maximum RSRP is not the beam that triggered the current report, how to report more important information when using the truncated MAC CE format is the problem that this solution aims to solve.

[0346] Step 1: The UE evaluates the measurement object based on the measurement events configured in the network. The measurement object includes at least one beam associated with at least one candidate cell.

[0347] Step 2: After the measurement event is met, the UE triggers measurement reporting.

[0348] In some embodiments, if the currently available uplink resources are insufficient to accommodate / transmit an MR MAC CE, the UE uses a truncated MR MAC CE.

[0349] In some embodiments, the measurement results of the beam carried in the MR MAC CE are (truncated) in at least one of the following ways:

[0350] Option 1: The measurement results of the triggered beam are placed at the forefront of the area carrying the measurement results in the MAC CE, and the measurement results of the triggered beam use absolute measurement values ​​(Absolute RSRP / RSRQ / SINR). For the measurement results of the remaining beams, the measurement results of the beam with the best measurement results are placed at the forefront of the remaining area carrying the measurement results in the MAC CE and use absolute measurement values. The measurement results of the remaining beams are all placed in the subsequent areas carrying the measurement results in the MAC CE using differential values ​​(differential RSRP / RSRQ / SINR) relative to the absolute measurement values ​​of the beam with the best measurement results. Here, the triggered beam corresponds to the first beam mentioned above.

[0351] For example, referring to Figure 6, the bits in the upper column of Figure 6 represent the bits corresponding to different bytes in the area carrying the measurement results in the MAC CE. The eight-bit bytes (Oct) N+x, etc., in the right column are used to indicate which byte each field is located in in the MAC CE. Here, N is the number of bytes occupied by the information before the measurement results in the MAC CE, x is the beam identifier of the beam and / or the byte in the area carrying the measurement results in the MAC CE, N is an integer greater than 1, and x is an integer greater than or equal to 1. Figures 7 and 8 below are similar and will not be described further.

[0352] The beam identifier (SSBRI / CSIRI of triggered beam) is located in byte N+1, and the measurement result of the triggered beam, which is the absolute RSRP value, is located in byte N+2. The beam identifier (SSBRI / CSIRI of best beam) is located in byte N+3, and the measurement result of the best beam, which is the absolute RSRP value, is located in byte N+4. The beam identifier (SSBRI / CSIRI of second-best beam) is located in byte N+5, and the measurement result of the best beam, which is the differential RSRP value, is located in byte N+6. The measurement results of the remaining beams are similar to those described above, and will not be illustrated further in this application. It should be noted that since the measurement results of some beams use differential values, reserved bits can be set.

[0353] Option 2: Place the measurement result of the beam with the best measurement result at the forefront of the area carrying the measurement result in the MAC CE. The measurement result of this beam uses the absolute measurement value. The measurement results of the remaining reported beams use the differential values ​​(differential RSRP / RSRQ / SINR) relative to the absolute measurement value of the beam with the best measurement result. They are arranged in order of the magnitude of the differential values ​​and placed in the subsequent areas carrying the measurement results in the MAC CE. Here, the other reported beams correspond to the second beam and / or the third beam mentioned above, and so on.

[0354] For example, referring to FIG7, the beam identifier (SSBRI / CSIRI of best beam) of the beam with the best measurement result is located in the (N+1)th byte, and the measurement result of the best beam is the absolute RSRP value, located in the (N+2)th byte; the beam identifier (SSBRI / CSIRI of second-best beam) of the second-best beam is located in the (N+3)th byte, and the measurement result of the best beam is the differential RSRP value, located in the (N+4)th byte. The measurement results of the remaining beams (including the trigger beam) are similar to those described above, and will not be illustrated further in this application. It should be noted that since the measurement results of some beams use differential values, reserved bits can be set.

[0355] Option 3: Place the measurement results of the triggered beam at the forefront of the area where the MAC CE carries the measurement results, and use the absolute measurement values ​​(Absolute RSRP / RSRQ / SINR) for the measurement results of the triggered beam. For the measurement results of the other beams, use the difference values ​​relative to the absolute measurement values ​​of the triggered beam.

[0356] For example, referring to FIG8, the beam identifier (SSBRI / CSIRI of triggered beam) of the triggered beam is located in the (N+1)th byte, and the measurement result of the triggered beam, which is the absolute RSRP value, is located in the (N+2)th byte; the beam identifier (SSBRI / CSIRI of other beam) of the first other beam is located in the (N+3)th byte, and the measurement result of the first other beam, which is the differential RSRP value, is located in the (N+4)th byte; the beam identifier (SSBRI / CSIRI of other beam) of the second other beam is located in the (N+5)th byte, and the measurement result of the second other beam, which is the differential RSRP value, is located in the (N+6)th byte. The measurement results of the remaining beams are similar to those described above, and will not be further illustrated in this application. It should be noted that since the measurement results of some beams use differential values, reserved bits can be set.

[0357] It should also be noted that in this case, the result of the differential value needs to be further distinguished between positive and negative. This positive or negative sign can be indicated in the MAC CE by the value corresponding to a 1-bit value, such as + / -, or it can be distinguished by the definition of the differential RSRP. Here, the trigger beam corresponds to the first beam mentioned above.

[0358] Option 4: Define a reference RSRP value. All beam measurements will use a differential value relative to the reference RSRP value. The measurement result of the trigger beam, i.e., the differential value, will be placed at the beginning of the area where the MAC CE carries the measurement results.

[0359] Here, the reference RSRP value can be based on network configuration or protocol conventions.

[0360] It should be noted that if the reference RSRP value is greater than or equal to the best measurement result, there is no need to distinguish between positive and negative values. However, if the reference RSRP value is less than the best measurement result, the differential value needs to be further distinguished between positive and negative values. This positive or negative sign can be indicated by the value corresponding to 1 bit in the MAC CE, such as + / -, or it can be distinguished by the definition of the differential RSRP.

[0361] It should also be noted that N in the N+x row number of the MAC CE example described in Figures 6 to 8 refers to the number of bytes occupied by the information before the measurement results are displayed in the MAC CE.

[0362] In some embodiments, the UE truncates measurement results for MAC CE, including one or more of the following methods:

[0363] Retain the relevant parameters of the triggered beam;

[0364] Cut off from bottom to top;

[0365] If resources are sufficient, option 2 can be truncated to the length including the trigger beam.

[0366] In some embodiments, the beam measurement results include the beam identifier and the beam measurement results.

[0367] The beam can be identified by SSB index / CSI-RS index or SSBRI / CSIRI.

[0368] The beam measurement results can be absolute RSRP / RSRQ / SINR or differential RSRP / RSRQ / SINR.

[0369] In some embodiments, the SSBRI / CSIRI length depends on the number of reference signals (RS) in the reference signal set (RS set).

[0370] For example, if the number of RSs in the RS set is 512, then 9 bits are required, and the length of the differential RSRP can be 3 / 4 / 5 / 6 bits.

[0371] In some embodiments, the (truncated) MR MAC CE also includes a measurement event ID and / or a measurement report configuration ID.

[0372] In some embodiments, the (truncated) MR MAC CE may also include an identifier of a satisfied condition, such as an enter condition or a leaving condition; optionally, it may also include an indication of whether a condition is satisfied, which may be a per beam indication, a per event indication, or a per MAC CE indication; optionally, it may also include a serving cell identifier, such as the measurement result of the beam being the beam measurement result of the serving cell; it may also include an identifier of subsequent indication, such as an indication of whether the remaining / truncated measurement reports will be transmitted subsequently.

[0373] In some embodiments, the UE sends a truncated MR MAC CE, and the UE performs subsequent MR MAC CE transmissions based on one or more of the following methods:

[0374] Continue using differential RSRP, which corresponds to the absolute RSRP in the previous truncated MR MAC CE;

[0375] The beam with the first / highest measurement result uses absolute RSRP, and the rest use differential RSRP;

[0376] Use absolute RSRP for all;

[0377] Use the same method as MR MAC CE or truncated MR MAC CE.

[0378] In some embodiments, whether the UE performs subsequent MR MAC CE transmissions is determined based on the following methods;

[0379] The state of the measured event is either triggered or not triggered.

[0380] Whether the network is enabled / activated will determine whether subsequent MR MAC CE operations are performed.

[0381] Whether the network can enable / activate periodic MR MAC CE;

[0382] Whether the measurement result of the triggered beam meets the threshold and / or TTT associated with the measurement event;

[0383] Did the trigger beam trigger a new measurement report, such as satisfying the leaving condition?

[0384] In summary, by placing the measurement results of the trigger beam that meets the trigger event in a prominent position in the measurement result carrying area of ​​the MAC CE, this application ensures that key information such as the measurement results of the trigger beam are promptly reported to the network side. This allows the network to determine whether to trigger a handover or reselection based on the reported measurement results of the first beam, thereby responding promptly to changes in network status.
