[0073] Receive third information, which is used to configure the fourth quantity.
[0074] In conjunction with some embodiments of the first aspect, in some embodiments, the first report includes resource identifiers for a fourth number of the first reference signal resources.
[0075] In conjunction with some embodiments of the first aspect, in some embodiments, the resource identifier included in the first report corresponds to at least one of the first cells.
[0076] In the above embodiments, when the terminal reports the first report, it specifically reports the resource identifiers of the first reference signal resources of several first cells. Furthermore, it specifies how many resource identifiers of the first reference signal resources should be reported for each first cell. This further refines the specific content of the first report, enabling the terminal to successfully report the first report to the network device.
[0077] In conjunction with some embodiments of the first aspect, in some embodiments, the frequencies of different first cells are the same or different, and the frequencies of the first cells and the serving cells of the terminal are the same or different.
[0078] In conjunction with some embodiments of the first aspect, in some embodiments, the triggering event includes at least one of the following:
[0079] The sum of the beam quality of the first beam and the first value is higher than the first threshold value;
[0080] The difference between the beam quality of the first beam and the first value is higher than the second threshold value;
[0081] The sum of the beam quality of the first beam and the first value is higher than the sum of the beam quality of the second beam and the second value by a third threshold value.
[0082] The difference between the beam quality of the first beam and the first value is higher than the difference between the beam quality of the second beam and the second value by a fourth threshold value.
[0083] In conjunction with some embodiments of the first aspect, in some embodiments, the beam quality of the first beam is the beam quality corresponding to the reference signal resources of the first cell; or, the beam quality of the first beam is the beam quality corresponding to the reference signal resources that have a QCL relationship with the reference signal resources of the first cell.
[0084] The beam quality of the second beam is the beam quality corresponding to the reference signal resources of the serving cell of the terminal.
[0085] In the above embodiments, the specific content of the triggering event is defined so that the terminal can successfully determine the reporting time of different candidate cells based on the triggering event, ensuring that the terminal reports the measurement report of the candidate cell in a timely and accurate manner at the appropriate time, avoiding the terminal from making useless reports at inappropriate times, and reducing signaling overhead and latency.
[0086] In conjunction with some embodiments of the first aspect, in some embodiments, the first value includes a frequency offset value corresponding to the frequency of the first cell; the second value includes a frequency offset value corresponding to the frequency of the serving cell of the terminal.

[0088] In the above embodiments, the first value in the triggering event can be the frequency offset value of the frequency corresponding to the first cell, or the cell offset value corresponding to the first cell, or the beam offset value corresponding to the first beam; and the second value can be the frequency offset value of the frequency corresponding to the serving cell, or the cell offset value corresponding to the serving cell, or the beam offset value corresponding to the second beam. This allows different first cells of different frequencies to correspond to different first values, or different first cells to correspond to different first values, or different first beams of the first cell to correspond to different first values, and different serving cells of different frequencies to correspond to different second values, or different serving cells to correspond to different second values, or different second beams of the serving cell to correspond to different second values. Therefore, by setting different first and second values, different first cells can correspond to different triggering conditions, different serving cells can correspond to different triggering conditions, different first beams can correspond to different triggering conditions, and different second beams can correspond to different triggering conditions. This ensures fairness in triggering the first report on different cells or different beams within a cell; alternatively, a first value can be set specifically for different first cells or different beams within a first cell, making the probability of triggering the first report higher on some first cells and lower on others. This allows the terminal to switch to the first cell with a higher probability of triggering the first report. By setting the first value, the terminal can be controlled to prioritize switching to a specific first cell, thus improving the controllability of communication.
[0089] In conjunction with some embodiments of the first aspect, in some embodiments, the reference signal resource includes at least one of the following:

[0093] When the first reference signal resource is a reference signal resource that has a QCL relationship with the reference signal resource of the first cell, the first reference signal resource is a CSI-RS resource, and the CSI-RS resource has a QCL relationship with the SSB resource of the first cell.
[0094] In the above embodiments, the specific resources that the first reference signal resource can be are defined. Thus, the terminal can send the first report by determining whether these resources meet the trigger event, thereby ensuring the successful transmission of the first report.
[0095] In conjunction with some embodiments of the first aspect, in some embodiments, the second beam includes at least one of the following:
[0096] The beam corresponding to the Transmission Configuration Indication (TCI) state indicated by the network device;

The processes and information interactions between these internal interfaces can be implemented by software or programs.
[0330] In some embodiments, the access network device may be composed of a central unit (CU) and a distributed unit (DU). The CU may also be called a control unit. The CU-DU structure can separate the protocol layer of the access network device. Some of the protocol layer functions are centrally controlled by the CU, while the remaining part or all of the protocol layer functions are distributed in the DU and centrally controlled by the CU. However, this is not the only possibility.
[0331] In some embodiments, the core network device may be a single device comprising one or more network elements, or multiple devices or a group of devices, each comprising all or part of one or more network elements. Network elements may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC). Alternatively, the core network device may also be a location management function network element. Exemplarily, the location management function network element includes a location server, which may be implemented as any of the following: a Location Management Function (LMF), an Enhanced Serving Mobile Location Centre (E-SMLC), a Secure User Plane Location (SUPL), and a Secure User Plane Location Platform (SUPLLP).
[0332] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.
[0333] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. The number and form of each main body are arbitrary. The connection relationship between the main bodies is illustrative. The main bodies may not be connected to each other or may be connected in any way. The connection may be direct or indirect, wired or wireless.
[0334] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 6th generation mobile communication system (6G), 5G New Radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio Access (NX), Future Generation Radio Access (FX), Global System for Mobile Communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., a combination of LTE or LTE-A with 5G).
[0335] Optionally, in a communication system, when a terminal reports a measurement report of a candidate cell to a network device, the network device typically first configures the reporting timing of the measurement report for the terminal, and then the terminal reports the measurement report based on the reporting timing configured by the network device. Optionally, the network device usually configures the terminal to report measurement reports periodically, semi-persistently, or non-periodically. However, in reality, beam quality changes are what the terminal can most promptly perceive, and the reporting timing configured by the network device (such as the period length of periodic reporting or the non-periodic reporting timing) may not be the most suitable. For example, if the reporting interval is too short, the optimal beam in two reports may be the same without change, thus wasting signaling; if the reporting interval is too long, there may be a situation where "when the beam quality changes, no report is made because the reporting timing has not yet arrived," thus affecting communication quality. Based on this, in order to determine the accurate reporting timing, a method of triggering the measurement report of a candidate cell through an event has been proposed. However, when triggering the measurement report of a candidate cell based on an event, the specific content of the measurement report is not yet clearly defined.
[0336] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, this embodiment of the disclosure relates to a communication method for a communication system 100, the method comprising:
[0337] Step 2101: The network device sends the fourth information to the terminal.
[0338] Optionally, this fourth information can be used to configure the first reference signal resource.
[0339] In some embodiments, the first reference signal resource may include one or more of the following:
[0340] At least one or more reference signal resources of a first cell;
[0341] One or more reference signal resources that have a quasi-co-location (QCL) relationship with the reference signal resources of the first cell.
[0342] For example, the first reference signal resource may include at least one of the following: reference signal resource #1 of the first cell #1, reference signal resource #2 of the first cell #1, reference signal resource #3 of the first cell #1, reference signal resource #1 of the first cell #2, reference signal resource #2 of the first cell #2, reference signal resource #4 that has a QCL relationship with reference signal resource #1 of the first cell #1, reference signal resource #5 that has a QCL relationship with reference signal resource #1 of the first cell #1, and reference signal resource #6 that has a QCL relationship with reference signal resource #1 of the first cell #2.
[0343] In some embodiments, the first cell can be a candidate cell for the terminal, and can also be used as the target cell for the terminal, meaning the terminal can switch from its current serving cell to the first cell. The first cell and the terminal's serving cell can have the same frequency (intra-frequency case); or the first cell and the terminal's serving cell can have different frequencies (inter-frequency case). In other embodiments, different first cells can have the same or different frequencies.
[0344] Optionally, the reference signal resource may include at least one of the following:
[0345] Synchronization Signal (SSB) resources;
[0346] Channel-state information reference signal (CSI-RS) resources.
[0347] In some embodiments, when the first reference signal resource is a reference signal resource of the first cell, the first reference signal resource can be an SSB resource, and the physical cell identifier (PCI) corresponding to the SSB resource can be the PCI of the first cell; or, when the first reference signal resource is a reference signal resource that has a QCL relationship with the reference signal resource of the first cell, the first reference signal resource can be a CSI-RS resource, and the CSI-RS resource can have a QCL relationship with the SSB resource of the first cell.
[0348] Step 2102: The terminal determines the first reference signal resource.
[0349] Optionally, in some embodiments, the terminal may determine the first reference signal resource based on the fourth information sent by the network device. For a detailed description of this part, please refer to the steps described above.
[0350] In other embodiments, the terminal may determine the first reference signal resource based on the Transmission Configuration Indication state (TCI). Optionally, in some embodiments, the terminal may determine the first reference signal resource based on one or more activated Transmission Configuration Indication states (activated TCI states) of at least one first cell activated by the network device. For example, the terminal may determine the reference signal resource indicated by one or more activated TCI states of at least one first cell as the first reference signal resource. In some embodiments, when the reference signal resources corresponding to certain activated TCI states include two reference signal resources, the reference signal resource with QCL type type D among the reference signal resources corresponding to the activated TCI state may be determined as the first reference signal resource. Optionally, the activated TCI state may be activated by the network device through Medium Access Control Control Element (MAC CE) signaling.
[0351] Alternatively, in other embodiments, the terminal can determine the first reference signal resource based on at least one TCI state configured by the network device for LTM. For example, the terminal can determine the reference signal resource indicated by at least one TCI state for LTM as the first reference signal resource. In some embodiments, when the reference signal resources corresponding to certain TCI states include two reference signal resources, the reference signal resource with QCL type type D among the reference signal resources corresponding to the TCI states can be determined as the first reference signal resource. Optionally, the aforementioned "at least one TCI state for LTM" can be configured by the network device through Radio Resource Control (RRC).
[0352] In some other embodiments, the terminal may determine the first reference signal resource based on a protocol agreement.
[0353] For a detailed introduction to the first reference signal resource, please refer to the steps described above.
[0354] Step 2103: The network device configures the trigger event to the terminal.
[0355] Optionally, the triggering event can be used to trigger a first report of the first reference signal resource. In some embodiments, different frequencies of the first cell correspond to different triggering conditions; optionally, the "triggering condition" here can be understood, for example, as a triggering threshold value corresponding to the triggering event, such as at least one of the following: a first value, a second value, a first threshold value, a second threshold value, a third threshold value, and a fourth threshold value. Optionally, the triggering condition can be used to trigger a first report of the first reference signal resource of the corresponding first cell.
[0356] Optionally, in some embodiments, "the triggering condition is used to trigger the first report of the first reference signal resource" can be understood as follows: the terminal measures the beam quality of the beam corresponding to the first reference signal resource, and when the measurement result of the first reference signal resource meets the triggering condition, the terminal can report the first report to the network device.
[0357] Optionally, the triggering event may include at least one of the following:
[0358] The sum of the beam quality of the first beam and the first value is higher than the first threshold value;
[0359] The difference between the beam quality of the first beam and the first value is higher than the second threshold value;
[0360] The sum of the beam quality of the first beam and the first value is higher than the sum of the beam quality of the second beam and the second value by a third threshold value.
[0361] The difference between the beam quality of the first beam and the first value is higher than the difference between the beam quality of the second beam and the second value by a fourth threshold value.
[0362] Optionally, different triggering conditions may include at least one of the following being different: a first value, a second value, a first threshold value, a second threshold value, a third threshold value, and a fourth threshold value.
[0363] Optionally, the first beam may include at least one of the following: a beam corresponding to the reference signal resources of the first cell, or a beam corresponding to reference signal resources that have a QCL relationship with the reference signal resources of the first cell. The beam quality of the first beam may be the beam quality corresponding to the reference signal resources of the first cell; or, the beam quality of the first beam may be the beam quality corresponding to reference signal resources that have a QCL relationship with the reference signal resources of the first cell.
[0364] Optionally, the beam quality of the second beam can be the beam quality corresponding to the reference signal resources of the serving cell of the terminal. In some embodiments, the second beam may include at least one of the following:
[0365] The beam corresponding to the indicated Transmission Configuration Indication state (indicated TCI state) of the network device;
[0366] The beam corresponding to the activated Transmission Configuration Indication state (activated TCI state) of the network device;
[0367] The beam corresponding to the reference signal resource with QCL type type D in the indicated TCI state;
[0368] The beam corresponding to the reference signal resource with QCL type type D in the activated TCI state.
[0369] Optionally, beam quality may include Layer 1 Reference Signal Received Power (L1-RSRP) and / or Layer 1 Signal to Interference plus Noise Ratio (L1-SINR).
[0370] Optionally, in some embodiments, when the indicated TCI state indicates multiple (e.g., two) reference signal resources, the first beam can be the beam corresponding to the reference signal resource with QCL type type D in the indicated TCI state; or, when the activated TCI state indicates multiple (e.g., two) reference signal resources, the first beam can be the beam corresponding to the reference signal resource with QCL type type D in the activated TCI state.
[0371] Optionally, the aforementioned TCI state may include at least one of the following: Unified Transmission Configuration Indication state (unifiedTCI state), Joint Transmission Configuration Indication state (jointTCI state), Down Link Transmission Configuration Indication state (DL TCI state), and Up Link Transmission Configuration Indication state (UL TCI state).
[0372] Optionally, in some embodiments, the first value may include a frequency specific offset of the frequency corresponding to the first cell, and the second value may include a frequency specific offset of the frequency corresponding to the serving cell of the terminal, wherein the first cell is the cell to which the reference signal resource corresponding to the first beam belongs, or the first cell is the cell to which the reference signal resource of the QCLsource of the reference signal resource corresponding to the first beam belongs. Alternatively, in other embodiments, the first value may include a cell specific offset of the first cell and / or a beam specific offset of the first beam; the second value may include a cell specific offset of the serving cell and / or a beam specific offset of the second beam.
[0373] Optionally, when the first value and the second value include a frequency offset value, it indicates that the first value and the second value are offset values defined for different frequencies. Optionally, the first value and / or the second value can satisfy at least one of the following:
[0374] The first value corresponding to the first cell at different frequencies may be the same or different;
[0375] The first cell has the same frequency as the serving cell, and its first value is 0.
[0376] The first cell has the same frequency as the serving cell, and the first value is the same as the second value.
[0377] The first cell has a different frequency than the serving cell, and the first value may be the same as or different from the second value.
[0378] Optionally, when the first value and the second value include cell offset values, it indicates that the first value and the second value are offset values defined for different cells. Optionally, the first value and / or the second value can satisfy at least one of the following:
[0379] The first value may be the same or different in different first-cell areas;
[0380] The first value corresponding to the first cell may be the same as or different from the second value corresponding to the serving cell;
[0381] The second value is the same for different second beams in the same serving cell.
[0382] Optionally, when the first value and the second value include a beam offset value, it indicates that the first value and the second value are offset values defined for different beams. Optionally, the first value and / or the second value can satisfy at least one of the following:
[0383] The second values corresponding to different second beams in the same serving cell may be the same or different;
[0384] The first values corresponding to different first beams in the same first cell may be the same or different.
[0385] Optionally, in some embodiments, when the first value includes a frequency offset value and a cell offset value, the priority of the terminal handover to that first cell can be increased or decreased by setting different first values for different first cells. Specifically, in some embodiments, when the triggering event includes: the sum of the beam quality of the first beam and the first value is higher than a first threshold value, and / or, the sum of the beam quality of the first beam and the first value is higher than a third threshold value than the sum of the beam quality of the second beam and the second value; in this case, if it is desired to increase the priority of the terminal handover to a certain first cell, the first value (such as the frequency offset value or the cell offset value) of the first cell can be set to a larger value, so that the sum of the beam quality of the first beam and the first value is a larger value, which can more easily exceed the first threshold value, or more easily exceed the sum of the beam quality of the second beam and the second value, thereby making it easier for the beam quality corresponding to the reference signal resources of the first cell to meet the triggering event, and easier to trigger the measurement reporting of the first cell, thus increasing the probability of the terminal handover to the first cell. Alternatively, if it is desired to reduce the priority of a terminal handover to a certain first cell, the first value (such as frequency offset value or cell offset value) of the first cell can be set to a smaller value, so that the sum of the beam quality of the first beam and the first value is a smaller value, which is not likely to exceed the first threshold value, or is not likely to exceed the sum of the beam quality of the second beam and the second value. This makes it less likely that the beam quality corresponding to the reference signal resources of the first cell will meet the triggering event, and less likely to trigger the measurement reporting of the first cell, thus reducing the probability of the terminal handover to the first cell.
[0386] Alternatively, in some other embodiments, when the triggering event includes: the difference between the beam quality of the first beam and the first value is higher than a second threshold value, and / or, the difference between the beam quality of the first beam and the first value is higher than a fourth threshold value than the difference between the beam quality of the second beam and the second value; in this case, if it is desired to increase the priority of the terminal handing over to a certain first cell, the first value (such as frequency offset value or cell offset value) of the first cell can be set to a smaller value, so that the difference between the beam quality of the first beam and the first value is a larger value, which can more easily be higher than the second threshold value, or more easily be higher than the difference between the beam quality of the second beam and the second value, thereby making it easier for the beam quality corresponding to the reference signal resources of the first cell to meet the triggering event, and easier to trigger the measurement reporting of the first cell, thus increasing the probability of the terminal handing over to the first cell. Alternatively, if it is desired to reduce the priority of a terminal handover to a certain first cell, the first value (such as frequency offset value or cell offset value) of the first cell can be set to a larger value, so that the difference between the beam quality of the first beam and the first value is a smaller value, which is not likely to exceed the second threshold value, or is not likely to exceed the difference between the beam quality of the second beam and the second value. This makes it difficult for the beam quality corresponding to the reference signal resources of the first cell to meet the triggering event, and it is not easy to trigger the measurement reporting of the first cell, thus reducing the probability of the terminal handover to the first cell.
[0387] Optionally, in some embodiments, when the first value includes a beam offset value, by setting different first values for different first beams in the first cell, the priority of the terminal switching to that first beam can be increased or decreased. Specifically, in some embodiments, when the triggering event includes: the sum of the beam quality of the first beam and the first value is higher than a first threshold value, and / or, the sum of the beam quality of the first beam and the first value is higher than a third threshold value than the sum of the beam quality of the second beam and the second value; in this case, if it is desired to increase the priority of the terminal switching to a certain first beam, the first value (such as the beam offset value) of the first beam can be set to a larger value, so that the sum of the beam quality of the first beam and the first value is a larger value, which can more easily exceed the first threshold value, or more easily exceed the sum of the beam quality of the second beam and the second value, thereby making it easier for the beam quality of the first beam to meet the triggering event, and more easily triggering the measurement reporting of the first beam, thus increasing the probability of the terminal switching to the first beam. Alternatively, if it is desired to reduce the priority of a terminal switching to a certain first beam, the first value (such as the beam offset value) of the first beam can be set to a smaller value, so that the sum of the beam quality of the first beam and the first value is a smaller value, which is not likely to exceed the first threshold value, or is not likely to exceed the sum of the beam quality of the second beam and the second value. This makes it less likely that the beam quality of the first beam will meet the trigger event and less likely to trigger the measurement reporting of the first beam, thus reducing the probability of the terminal switching to the first beam.
[0388] Optionally, in some embodiments, when the triggering event includes: the difference between the beam quality of the first beam and the first value is higher than a second threshold value; and / or, the difference between the beam quality of the first beam and the first value is higher than a fourth threshold value than the difference between the beam quality of the second beam and the second value; in this case, if it is desired to increase the priority of the terminal switching to a certain first beam, the first value (such as the beam offset value) of the first beam can be set to a smaller value, so that the difference between the beam quality of the first beam and the first value is a larger value, which can more easily be higher than the second threshold value, or more easily be higher than the difference between the beam quality of the second beam and the second value, thereby making it easier for the beam quality of the first beam to meet the triggering event, and more easily triggering the measurement reporting of the first beam, thus increasing the probability of the terminal switching to the first beam. Alternatively, if it is desired to reduce the priority of a terminal switching to a certain first beam, the first value (such as the beam offset value) of the first beam can be set to a larger value, so that the difference between the beam quality of the first beam and the first value is a smaller value, which is not likely to exceed the second threshold value, or is not likely to exceed the difference between the beam quality of the second beam and the second value. This makes it less likely that the beam quality of the first beam will meet the trigger event and less likely to trigger the measurement reporting of the first beam, thus reducing the probability of the terminal switching to the first beam.
[0389] Optionally, in some embodiments, the first report described above may include a resource identifier of at least one first reference signal resource. In some embodiments, the resource identifier in the first report may include at least: a resource identifier of the first reference signal resource that satisfies the triggering event.
[0390] Optionally, in some embodiments, the network device can configure trigger events to the terminal via Radio Resource Control (RRC).
[0391] Furthermore, in some embodiments, the term "beam" is merely an exemplary designation of this disclosure, and it can also be other designations. For example, a beam can be referred to as: beam, common beam, spatial Rx parameter, quasi-co-location Type (QCL Type) D, spatial setting, spatial reception filter, spatial transmission filter, spatial domain filter, TCI state, indicated TCI state, joint Transmission Configuration Indication state (joint TCI state), downlink transmission configuration indication state (DL TCI state), uplink transmission configuration indication state (UL TCI state), unified transmission configuration indication state (unifiedTCI state), and common transmission configuration indication state (common TCI state). State), spatial relation information, etc.
[0392] Step 2104: The terminal determines the triggered event.
[0393] Optionally, the terminal may receive trigger events configured by the network device, or the terminal may determine the trigger events based on protocol agreements.
[0394] For a detailed description of the triggering event, please refer to step 2101 above.
[0395] Step 2105: The network device sends at least one of the first information, the second information, and the third information to the terminal.
[0396] In some embodiments, the first information can be used to configure at least one of a first quantity and a second quantity. Optionally, the first quantity can be: the number of first cells corresponding to resource identifiers included in the first report, where the first quantity is a positive integer; that is, the first report can include resource identifiers of first reference signal resources of a first quantity of first cells. Optionally, the second quantity can be: the number of first reference signal resources corresponding to one first cell in the first report; the second quantity is a non-negative integer; optionally, the second quantities corresponding to different first cells may be the same or different. That is, one first cell in the first report can include resource identifiers of a second quantity of first reference signal resources.
[0397] Optionally, in some embodiments, the second number corresponding to the second cell in at least one first cell is greater than or equal to the second number corresponding to the third cell; wherein, the second cell can be: the first cell where the first reference signal resource that satisfies the triggering event is located; the third cell can be: at least one cell in the first cell other than the second cell.
[0398] For example, suppose there are three first cells, namely first cell #1, first cell #2, and first cell #3. The first reference signal resources corresponding to first cell #1 include reference signal resource #1 and reference signal resource #2; the first reference signal resources corresponding to first cell #2 include reference signal resource #3; and the first reference signal resources corresponding to first cell #3 include reference signal resource #4. If reference signal resources #1, #2, and #4 satisfy a triggering event, then first cell #1 and first cell #3 can be identified as second cells, and first cell #2 as third cell.
[0399] Optionally, in some embodiments, the second information described above can be used to configure at least one of the first quantity and the third quantity; wherein, a detailed description of the first quantity can be found in the above description; optionally, the third quantity can be: the maximum number of first reference signal resources corresponding to a first cell in the first report; the third quantity is a non-negative integer; optionally, the third quantity corresponding to different first cells may be the same or different. That is, a first cell in the first report can include at most a third quantity of resource identifiers for first reference signal resources.
[0400] Optionally, in some embodiments, the aforementioned third information can be used to configure a fourth quantity, which can be the total number of first reference signal resources corresponding to the first report, that is: the first report may include resource identifiers of a fourth quantity of first reference signal resources.
[0401] Step 2106: The terminal determines one or more of the first quantity, second quantity, third quantity, and fourth quantity.
[0402] Optionally, the terminal may receive one or more of the first, second, third, and fourth quantities configured by the network device; alternatively, the terminal may determine one or more of the first, second, third, and fourth quantities based on a protocol agreement. For detailed information on this part, please refer to the steps described above.
[0403] Step 2107: The first reference signal resource satisfies the trigger event, and the terminal sends a first report to the network device.
[0404] Optionally, the terminal may send a first report to the network device when the measurement result of the first reference signal resource meets the trigger event. In some embodiments, the measurement result may be the beam quality of the beam corresponding to the first reference signal resource, such as Layer 1 Reference Signal Received Power (L1-RSRP) and / or Layer 1 Signal to Interference plus Noise Ratio (L1-SINR).
[0405] Optionally, in some embodiments, the first report may include resource identifiers of first reference signal resources of a first number of first cells, and each first cell in the first report may correspond to resource identifiers of a second number of first reference signal resources. In this case, the number of resource identifiers included in the first report is the sum of the second numbers corresponding to the first number of first cells. For example, assuming the first number is 2, and the second numbers corresponding to the 2 first cells are N1 and N2 respectively, then the number of resource identifiers included in the first report is N1 + N2. Therefore, the number of resource identifiers included in the first report is fixed, thereby making the size of the signaling (such as uplink control information (UCI)) carrying the first report fixed, which facilitates the network device to decode the signaling and improves communication efficiency.
[0406] In some embodiments, the first report may include resource identifiers of first reference signal resources of at least one fourth cell; the number of first reference signal resources corresponding to each fourth cell in the first report is less than or equal to the third number corresponding to the fourth cell, and greater than 0. Optionally, the fourth cell may be the first cell where the first reference signal resource that satisfies the triggering event is located, that is, the fourth cell may be the second cell mentioned above, or the fourth cell may be any first cell, that is, the fourth cell may be the second cell or the third cell mentioned above. Optionally, in some embodiments, the first report may only include resource identifiers of first reference signal resources of at least one second cell, or in some embodiments, the first report may include resource identifiers of first reference signal resources of at least one second cell and resource identifiers of first reference signal resources of at least one third cell; wherein, the number of first reference signal resources corresponding to the second cell may be greater than or equal to the number of first reference signal resources corresponding to the third cell.
[0407] In some embodiments, the first report may include resource identifiers of a fourth number of first reference signal resources. Optionally, the resource identifiers included in the first report may correspond to at least one first cell. For example, in some embodiments, the first report may include resource identifiers of the fourth number of first reference signal resources whose measurement results rank among all first reference signal resources; and the number of first reference signal resources corresponding to the second cell in the first report may be greater than or equal to the number of first reference signal resources corresponding to the third cell. In this case, the number of resource identifiers included in the first report is also fixed at a fourth number, thereby making the size of the signaling (such as UCI) carrying the first report fixed, which facilitates network devices in decoding the signaling and improves communication efficiency.
[0408] In some embodiments, the first report may include resource identifiers of first reference signal resources of a first number of first cells. The number of first reference signal resources corresponding to each first cell in the first report may be greater than 0, less than or equal to a third number corresponding to that first cell. In some embodiments, the first report may include resource identifiers of first reference signal resources of the first number of first cells with the highest measurement results. The resource identifier corresponding to each first cell in the first report includes at least the resource identifier of the first reference signal resource with the best measurement result for that first cell. For example, the measurement results of all first reference signal resources may be sorted to determine the first number of first cells with the highest measurement results, and the first reference signal resources with the best measurement results corresponding to each of the first number of first cells may be determined; or, the measurement results of the first reference signal resources of each first cell may be sorted to determine the first reference signal resource with the best measurement result for each first cell, and then the first reference signal resources with the best measurement results for each first cell may be sorted again to determine the first number of first cells with the highest measurement results, and the first reference signal resources with the best measurement results corresponding to each of the first number of first cells may be determined. Optionally, in some embodiments, for the top number of first cells in the measurement results in the first report, in addition to including the resource identifier of the first reference signal resource with the best measurement result, the resource identifier of other first reference signal resources of the first cell may also be included. Optionally, "other first reference signal resources" here can be: the top N3 first reference signal resources in the first cell besides the first reference signal resource with the best measurement result; or, the "other first reference signal resources" can be: any N3 first reference signal resources of the first cell; wherein, N3 is greater than 0 and less than the third number corresponding to the first cell. It should be noted that "other first reference signal resources" can also be determined by other methods, and are not limited to the two examples above. This disclosure does not specifically limit them.
[0409] Optionally, in some embodiments, the resource identifiers corresponding to different first reference signal resources of the same first cell may be different, and the resource identifiers corresponding to the first reference signal resources of different first cells may also be different.
[0410] Optionally, when the first reference signal resource is an SSB resource, Table 1 shows a correspondence between a first reference signal resource and a resource identifier (entry) as illustrated in an embodiment of this disclosure.
[0411] Table 1
[0412] As shown in Table 1, the first cell CellID#i corresponds to three first reference signal resources, namely: SSB#n, SSB#n+l, and SSB#n+h. The resource identifier corresponding to SSB#n is "0", the resource identifier corresponding to SSB#n+l is "1", and the resource identifier corresponding to SSB#n+h is "2". And so on. Assuming each first cell corresponds to s first reference signal resources, the resource identifiers corresponding to the s first reference signal resources of the first first cell are 0 to s-1, the resource identifiers corresponding to the s first reference signal resources of the second first cell are s to 2s-1, the resource identifiers corresponding to the s first reference signal resources of the third first cell are 2s to 3s-1, and so on.
[0413] It should be noted that the above is only an example of the "correspondence between reference signal resources and resource identifiers". Other correspondences are also within the scope of protection of this disclosure, and this disclosure does not make specific limitations on them.
[0414] Furthermore, in some embodiments, the first report described above may also include at least one of the following:
[0415] Measurement results of the first reference signal resource;
[0416] The event ID that triggered the event;
[0417] The report configuration identifier is reportconfigID.
[0418] Step 2108: The network device determines the target cell and / or target beam of the terminal based on the first report.
[0419] Optionally, the first report can be used for LTM (Low-Temperature Measurement). That is, after receiving the first report, the network device can determine, based on the measurement results of the first reference signal resource in the first report, a first cell with better beam quality as the terminal's target cell, and use the beam corresponding to the first reference signal resource with better beam quality in that target cell as the terminal's target beam in that target cell. Then, the network device can instruct the terminal to hand over to the target cell and instruct the terminal to use the target beam in the target cell to communicate with the network device. Optionally, the target cell can be understood as the cell to which the terminal is about to hand over, and the target beam can be understood as the beam to be used by the terminal after handing over to the target cell.
[0420] Step 2109: The network device indicates the target cell and / or target beam to the terminal.
[0421] Step 2110: The terminal switches to the target cell and / or target beam.
[0422] Optionally, after the terminal switches to the target cell and target beam, it can use the target beam to receive downlink signals sent by the network device. In some embodiments, the terminal can also determine its corresponding uplink transmission beam based on the target beam and use the uplink transmission beam to send uplink signals to the network device.
[0423] In the above embodiments, the terminal determines the first reference signal resources corresponding to one or more first cells, and when the first reference signal resources meet the trigger event, it sends a first report, which may include the resource identifier of at least one first reference signal resource. Therefore, this disclosure defines the specific reporting content of the first report for the scenario where "the terminal reports the first report at the cell level based on the trigger event." This reporting content may, for example, be the resource identifier of the first reference signal resource. This ensures that the terminal can successfully report the first report at the cell level based on the trigger event, ensuring the smooth execution and stability of the terminal's measurement reporting. Furthermore, in this disclosure, when the terminal reports the first report at the cell level based on the trigger event, the terminal can report the resource identifier of at least one first reference signal resource to the network device. This allows the network device to clearly identify which first reference signal resources are specifically included in the first report, enabling the network device to perform corresponding scheduling based on the first reference signal resources included in the first report, ensuring the accuracy and efficiency of network device scheduling.
[0424] In the above embodiments, the first value in the triggering event can be the frequency offset value of the frequency corresponding to the first cell, or the cell offset value corresponding to the first cell, or the beam offset value corresponding to the first beam; and the second value can be the frequency offset value of the frequency corresponding to the serving cell, or the cell offset value corresponding to the serving cell, or the beam offset value corresponding to the second beam. This allows different first cells of different frequencies to correspond to different first values, or different first cells to correspond to different first values, or different first beams of the first cell to correspond to different first values, and different serving cells of different frequencies to correspond to different second values, or different serving cells to correspond to different second values, or different second beams of the serving cell to correspond to different second values. Therefore, by setting different first and second values, different first cells can correspond to different triggering conditions, different serving cells can correspond to different triggering conditions, different first beams can correspond to different triggering conditions, and different second beams can correspond to different triggering conditions. This ensures fairness in triggering the first report on different cells or different beams within a cell; alternatively, a first value can be set specifically for different first cells or different beams within a first cell, making the probability of triggering the first report higher on some first cells and lower on others. This allows the terminal to switch to the first cell with a higher probability of triggering the first report. By setting the first value, the terminal can be controlled to prioritize switching to a specific first cell, thus improving the controllability of communication.
[0425] The communication method involved in the embodiments of this disclosure may include at least one of steps 2101 to 2110. For example, step 2101 may be implemented as a standalone embodiment, step 2102 may be implemented as a standalone embodiment, step 2103 may be implemented as a standalone embodiment, and step 2101+S2102 may be implemented as a standalone embodiment, but is not limited thereto.
[0426] In this implementation or embodiment, unless there is contradiction, each step can be independent, arbitrarily combined or exchanged in order, optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementations or other embodiments.

[0563] In some embodiments, the above methods may include the methods described in the embodiments of the communication system side, terminal side, network device side, etc., which will not be repeated here.
[0564] The communication method involved in the embodiments of this disclosure may include at least one of steps 5101 to 5104. For example, step 5101 may be implemented as a separate embodiment, and step 5102 may be implemented as a separate embodiment, but are not limited thereto.
[0565] In this implementation or embodiment, unless there is contradiction, each step can be independent, arbitrarily combined or exchanged in order, optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other implementations or other embodiments.
[0566] The following is an exemplary description of the above method.
[0567] 1. The terminal determines a first reference signal resource, which is used to determine a new beam in an event (also known as a triggering condition). When the first reference signal resource meets the event triggering condition, the terminal sends a first report. The first reference signal resource is either a reference signal resource corresponding to a candidate cell or a reference signal resource with a QCL relationship to the reference signal resource of the candidate cell. The first report contains reference signal identification information for the first reference signal resource of at least one candidate cell.
[0568] a) The beam can be called beam, spatial Rx parameter, QCL (quasi-co location) Type D, spatial setting, spatial reception filter, spatial transmission filter, spatial domain filter, TCI state, indicated TCI state, joint TCI state, DL TCI state, UL TCI state, unified TCI state, common TCI state, spatialrelationinfo, etc.
[0569] b) The first report is used for L1 / L2 triggered mobility (LTM)
[0570] c) The candidate cell is the non-serving cell of the terminal. The candidate cell is used to determine one cell as the target cell, that is, the cell to which the terminal will hand over.
[0571] 2. The first report includes identification information corresponding to at least one first reference signal resource of at least one candidate cell, and at least one first reference signal satisfies the triggering condition of the event.
[0572] a) The base station configuration first report contains the identification information corresponding to the reference signal resources of M candidate cells, and each candidate cell reports the identification information corresponding to N reference signal resources.
[0573] i. Where M is greater than or equal to 1, and N is greater than or equal to 1. For different candidate cells, the value of N can be the same, or the value of N can be configured independently.
[0574] ii. The case where the N value is configured independently is as follows:
[0575] 1. Because the first report must include the identification information corresponding to at least one first reference signal resource that triggered the event, for example, the event is as follows: the sum or difference between the new beam and a frequency-related offset is one threshold higher than the quality of the current beam. That is, the first report must contain at least one new beam that is better than the current beam. And this new beam corresponds to, for example, candidate cell #1, which means that the terminal is relatively close to candidate cell #1. Therefore, it can be configured that: for candidate cells that contain a new beam that meets the triggering conditions, the N value is N1, and for candidate cells that do not contain a new beam that meets the triggering conditions, the N value is N2. The following uses M=2 as an example.
[0576] a) The base station can explicitly configure the values of N1 and N2. The value of N1 is greater than 1, and the value of N2 can be less than N1 and greater than or equal to 0, where a value of 0 indicates that no report is made. The advantage of the base station explicitly configuring the values of N1 and N2 is that the number of reference signal identifiers included in the beam report is fixed, so the size of the UCI corresponding to the beam report is fixed, making decoding by the base station more convenient.
[0577] b) In addition, the values of N1 and N2 may simply be the maximum values configured by the base station, while the actual values of N1 and N2 included in the first report are determined by the terminal.
[0578] i. For example, in one scenario, the terminal only reports the identifiers of reference signal resources that meet the triggering conditions. In this case, the identifiers of the reference signal resources reported by the terminal may not correspond to several cells, and the number may differ from the number M configured by the base station, because there may only be one candidate cell whose reference signal resources meet the triggering conditions. Of course, the number of candidate cells configured by the base station for measurement is definitely greater than or equal to M.
[0579] ii. In the second scenario, the terminal reports a total of N1+N2 reference signal resource identifiers in the first report (which may include identifiers of reference signal resources that do not meet the triggering conditions). However, the specific number of reference signal resource identifiers for each candidate cell is uncertain. The terminal can sort the L1-RSRPs corresponding to all reference signal resource identifiers of all candidate cells and report the identifiers of reference signal resources with higher L1-RSRPs. Alternatively, the terminal can determine that it can report more reference signal resource identifiers for candidate cells that meet the triggering conditions and report fewer identifiers for candidate cells that do not meet the triggering conditions. The specific reference signal resource identifier refers to the entry (see the detailed description in item 7 below). In this method, the number of reference signal resource identifiers is also fixed.
[0580] iii. In the third scenario, for example, if the base station is configured to report reference signal resource identifiers for M candidate cells, the terminal needs to ensure that the reported reference signal resource identifiers correspond to at least M different candidate cells. That is, for each of the M different candidate cells, at least one reference signal resource is reported, and the remaining number can be allocated by the terminal. For instance, the terminal sorts the L1-RSRPs corresponding to all reference signal identifiers of the multiple candidate cells configured by the base station for measurement, and also sorts the L1-RSRPs of the reference signal resource identifiers within each candidate cell. Each candidate cell selects its strongest L1-RSRP and sorts it again, finding the M candidate cells corresponding to the M strongest L1-RSRPs. The first report then only includes the reference signal resource identifiers corresponding to these M candidate cells. That is, the reference signal resource identifiers corresponding to the strongest L1-RSRPs within these M candidate cells are already included in the first report. How to determine the other reference signal resource identifiers in these M candidate cells can refer to the methods in the first or second scenario. The final number of all included reference signal identifiers can be equal to or less than M*N.
[0581] 1. For example, if a base station is configured to measure reference signal resources in three candidate cells, and the strongest L1-RSRP is higher in two of these candidate cells, the terminal reports the identifier of the reference signal resource corresponding to the strongest L1-RSRP in those two candidate cells. This means that two reference signal resource identifiers have been identified as corresponding to two different candidate cells. Which of the other reference signal resource identifiers corresponds to in these two candidate cells can be determined by the terminal itself, or they can be excluded from the first report.
[0582] b) The candidate cells included in the first report all correspond to the same frequency f, or correspond to different frequencies f.
[0583] i. The frequency of f can be the same as or different from that of the serving cell.
[0584] 3. Based on 1 or 2, the event includes
[0585] a) The sum or difference between the new beam quality and a frequency-dependent second offset is higher than a threshold.
[0586] i. The new beam is also called the target beam.
[0587] 1. Mn + offset(f) > threshold2
[0588] The offset(f) is frequency-dependent. For example, if the event is to determine whether the beam of a candidate cell at frequency f1 is good, then the offset value is offset(f1); if the event is to determine whether the beam of a candidate cell at frequency f2 is good, then the offset value is offset(f2). offset(f1) and offset(f2) can be different values or the same value. If the candidate cell is on the same frequency as the current serving cell, then offset(f) can be 0. And / or if it is not on the same frequency as the current serving cell, the offset value is not 0 and takes the same value for different frequencies.
[0589] b) The sum or difference between the new beam and a frequency-dependent offset is one threshold higher than the current beam quality.
[0590] i.Mn+offset(fn)>Ms+offset(fs)+threshold3
[0591] The offset(f) is frequency-dependent. For example, if the event is to determine whether the beam in a candidate cell at frequency f1 is better than the current beam, then the offset value is offset(f1); if the event is to determine whether the beam in a candidate cell at frequency f2 is better than the current beam, then the offset value is offset(f2). offset(f1) and offset(f2) can be different values or the same value. If the candidate cell is on the same frequency as the current serving cell, offset(f) can be 0. And / or if it is not on the same frequency as the current serving cell, the offset value is not 0 and takes the same value for different frequencies.
[0592] 4. Based on point 1, when the first reference signal resource is used to determine a new beam, the first reference signal resource can be an SSB or a CSI-RS.
[0593] a) The PCI corresponding to the SSB is the PCI of the candidate cell.
[0594] b) CSI-RS has a QCL relationship with the SSB of the candidate cell.
[0595] 5. Based on 1, the candidate cell and the terminal's serving cell are at the same frequency (intra-frequency), or the candidate cell and the terminal's serving cell are at different frequencies (inter-frequency).
[0596] 6. Based on 1, the current beam is determined based on the indicated TCI state or the activated indicated TCI state.
[0597] a) The reference signal resource corresponding to the current beam is either the indicated TCI state or the activated indicated TCI state. If there are two reference signal resources, the reference signal resource corresponding to QCL Type D is used.
[0598] 7. Based on 1, the first report includes the entry of the reference signal identifier corresponding to the new beam in the list configured in the base station RRC, L1-RSRP.
[0599] The entry for the reference signal identifier corresponding to the new beam is shown in the table below.
[0600] The above is just an example. The reference signal entries for the first cell are numbered sequentially from 0 to s-1, with each cell corresponding to s reference signal identifiers; then the reference signal entries for the second cell are s to 2s-1, and the reference signal entries for the third cell are 2s to 3s-1, and so on.
