[0034] The embodiment of the present disclosure provides a determination method, a communication device, a communication system and a storage medium.

[0035] In a first aspect, an embodiment of the present disclosure provides a determination method, executed by a terminal, comprising:

[0036] determining a triggering event; the triggering event is used to trigger a first report of a first reference signal resource; the first reference signal resource comprises one or more of the following: at least one reference signal resource of a first cell, one or more reference signal resources of at least one second cell, one or more reference signal resources having a quasi co-location, QCL, relationship with a reference signal resource of a second cell.

[0037] In the above embodiments, the triggering event determined by the terminal can be used to trigger the first report of one or more cell reference signal resources. It can be seen that the present disclosure defines a triggering event with different cells as granularity, which can trigger the first report of different cell reference signal resources, so that the triggering event of the present disclosure can be applied to the LTM scenario. When LTM is to be performed, the terminal can determine the triggering event by using the method of the present disclosure, and determine the reporting time of the measurement report of different candidate cells based on the triggering event. By flexibly setting the triggering event, the terminal can timely and accurately report the measurement report of the candidate cell at the appropriate time, avoiding the situation that "the reporting interval configured by the network device is too short, so that the best beams of two reports are the same and do not change, thereby wasting signaling, and the reporting interval configured by the network device is too long, so that when the beam quality changes, the beam report is not sent due to not reaching the reporting time, thereby affecting the communication quality", thereby reducing the signaling overhead and the time delay, and ensuring that the measurement report can be reported in time when the beam quality changes, and the communication quality is ensured.

[0038] In some embodiments in combination with the first aspect, in some embodiments, the first report is used for layer 1, L1, or layer 2, L2, triggered mobility, LTM.

[0044] The first reference signal resource is a CSI-RS resource when the first reference signal resource has a QCL relationship with a reference signal resource of the second cell.

[0045] With reference to the first aspect, in some embodiments, the second cell has the same frequency as or a different frequency from the first cell.

[0046] In the above embodiments, the role of the first report, the resources included in the first reference signal resource, the cells of the first cell and the second cell, and the frequency relationship between the first cell and the second cell are defined to clarify the application scenarios of the method of the present disclosure and ensure that the method of the present disclosure can be successfully performed in the corresponding application scenarios.

In this way, the fairness of the first report triggering on different cells or different beams in a cell can be ensured; or for different second cells or different beams in a second cell, the second value can be set purposefully, so that the possibility of the first report triggering on part of the second cells is higher, and the possibility of the first report triggering on another part of the second cells is lower, so that the terminal can switch to the second cell with a higher possibility of the first report triggering with a higher probability, thereby by setting the second value, the terminal can be controlled to switch to a specific second cell, and the controllability of the communication is improved.

The network element can be virtual or physical. The core network includes at least one of an evolved packet core (EPC), a 5G core network (5GCN), and a next-generation core (NGC), for example.

[0207] It can be understood that the communication system described in the embodiments of the present disclosure is for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and does not constitute a limitation on the technical solutions proposed in the embodiments of the present disclosure. It can be known by those skilled in the art that, as the system architecture evolves and new business scenarios appear, the technical solutions proposed in the embodiments of the present disclosure are also applicable to similar technical problems.

[0208] The following embodiments of the present disclosure can be applied to the communication system 100 shown in FIG. 1, or part of the main bodies, but are not limited thereto. The main bodies shown in FIG. 1 are illustrative, and the communication system can include all or part of the main bodies in FIG. 1, or other main bodies other than those in FIG. 1. The number and form of each main body is arbitrary, and the connection relationship between the main bodies is illustrative. The main bodies can be connected or not connected, and the connection can be in any manner, can be direct or indirect, and can be wired or wireless.

[0209] Embodiments of the present disclosure 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 (registered trademark)), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi (registered trademark)), IEEE 802.16 (WiMAX (registered trademark)), IEEE 802.20, Ultra-WideBand (UWB), Bluetooth (Bluetooth (registered trademark)), Public Land Mobile Network (PLMN) network, Device-to-Device (D2D) system, Machine to Machine (M2M) system, Internet of Things (IoT) system, Vehicle-to-Everything (V2X), system using other determination methods, next-generation system expanded based thereon, and the like. Further, a plurality of systems can be applied in combination (for example, combination of LTE or LTE-A and 5G, and the like).

[0210] Optionally, in the communication system, when the terminal reports the measurement report of the candidate cell to the network device, the network device usually configures the reporting occasion of the measurement report for the terminal first, and then the terminal reports the measurement report based on the reporting occasion configured by the network device. Optionally, the network device usually configures the terminal to report the measurement report periodically, semi-persistently, or aperiodically. However, in fact, the beam quality change is most timely known by the terminal, and the reporting occasion configured by the network device (such as the period length of the periodic reporting or the reporting occasion of the aperiodic reporting) is not necessarily the most appropriate. For example, if the reporting interval is too short, the best beams of two reports may be the same, without change, thereby wasting signaling; if the reporting interval is too long, the situation that "when the beam quality changes, no report is made because the reporting occasion has not been reached" may occur, thereby affecting the communication quality. Based on this, in order to determine the accurate reporting occasion, a method of triggering the measurement report of the candidate cell by the event is proposed. However, the current triggering events are all used to trigger the measurement report of the beams in the same cell, and there is no triggering event for triggering the measurement report of different candidate cells, and how to define the event content of the "triggering event for triggering the measurement report of different candidate cells" is a technical problem to be solved urgently.

[0211] FIG. 2 is an interaction schematic diagram of a determination method according to an embodiment of the present disclosure. As shown in FIG. 2, the embodiment of the present disclosure relates to a determination method for the communication system 100, and the above method comprises:

[0212] Step 2101, the network device configures a triggering event for the terminal.

[0213] Optionally, the triggering event can be used to trigger a first report of a first reference signal resource. Optionally, "the triggering event is used to trigger the first report of the first reference signal resource" herein can be understood as, for example, 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 event, the terminal can report the first report to the network device.

[0214] Optionally, the first reference signal resource can include one or more of the following:

In this case, the frequency of the second cell can be the same as that of the first cell, i.e., intra-frequency; or the frequency of the second cell can be different from that of the first cell, i.e., inter-frequency. Alternatively, the frequencies of different second cells can be the same or different.

[0219] Alternatively, in some embodiments, the second cells of different frequencies correspond to the same triggering event.

[0225] Alternatively, in some embodiments, the reference signal resource described above can include at least one of the following:

[0226] a synchronization signal block (SSB) resource;

[0227] a channel-state information reference signal (CSI-RS) resource.

[0228] In some embodiments, when the first reference signal resource is a reference signal resource of the second 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 second 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 second 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 second cell.

[0229] Optionally, in some embodiments, the triggering event may include at least one of the following:

[0235] The difference between the beam quality of the second beam and the second value is higher than the difference between the beam quality of the first beam and the first value by a sixth threshold value.

[0236] Optionally, the beam quality of the first beam can be the beam quality corresponding to the reference signal resources of the first cell. In some embodiments, the first beam may include at least one of the following:

[0237] The beam corresponding to the indicated Transmission Configuration Indication state (indicated TCI state) of the network device;

[0239] The beam corresponding to the reference signal resource with QCL type type D in the indicated TCI state;

[0240] a beam corresponding to a reference signal resource with QCL type D in the indicated TCI state.

[0241] Optionally, in some embodiments, when the indicated TCI state indicates multiple reference signal resources (e.g., two), the first beam can be a beam corresponding to a reference signal resource with QCL type D in the indicated TCI state; or when the activated TCI state indicates multiple reference signal resources (e.g., two), the first beam can be a beam corresponding to a reference signal resource with QCL type D in the activated TCI state.

[0243] Optionally, the second beam can include at least one of a beam corresponding to a reference signal resource of the second cell and a beam corresponding to a reference signal resource having a QCL relationship with the reference signal resource of the second cell. The beam quality of the second beam can be a beam quality corresponding to the reference signal resource of the second cell, or the beam quality of the second beam can be a beam quality corresponding to a reference signal resource having a QCL relationship with the reference signal resource of the second cell.

[0244] Optionally, the beam quality can include a Layer 1 Reference Signal Received Power (L1-RSRP) and / or a Layer 1 Signal to Interference plus Noise Ratio (L1-SINR).

[0245] In some embodiments, the different trigger conditions can include at least one of the following different: a first value, a second value, a first threshold value, a second threshold value, a third threshold value, a fourth threshold value, a fifth threshold value, a sixth threshold value. Optionally, in some embodiments, the first value can include a frequency specific offset of a first cell corresponding frequency, and the second value can include a frequency specific offset of a second cell corresponding frequency, wherein the first cell is a cell to which a reference signal resource corresponding to the first beam belongs, and the second cell is a cell to which a reference signal resource corresponding to the second beam belongs or a cell to which a reference signal resource corresponding to a QCL source of the reference signal resource of the second beam belongs. Alternatively, in some other embodiments, the first value can include a cell specific offset of the first cell and / or a beam specific offset of the first beam, and the second value can include a cell specific offset of the second cell and / or a beam specific offset of the second beam.

[0246] Optionally, when the first value and the second value include a frequency specific offset, it means that the first value and the second value are offset values defined for different frequencies, and optionally, the first value and / or the second value can satisfy at least one of the following:

[0247] The second values corresponding to the second cells of different frequencies are the same or different;

[0248] The first cell and the second cell have the same frequency, and the second value is 0;

[0249] The first cell and the second cell have the same frequency, and the first value and the second value are the same;

[0250] The first cell and the second cell have different frequencies, and the first value and the second value are the same or different.

[0251] Optionally, when the first value and the second value include a cell specific offset, it means that the first value and the second value are offset values defined for different cells, and optionally, the first value and / or the second value can satisfy at least one of the following:

[0252] The second values of different second cells are the same or different;

[0253] The first value corresponding to the first cell is the same as or different from the second value corresponding to the second cell.

[0254] The second values corresponding to different second beams of the same second cell are the same.

[0255] Optionally, when the first value and the second value comprise 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 conditions:

[0256] The second values corresponding to different second beams in the same second cell are the same or different.

[0257] The first values corresponding to different first beams in the same first cell are the same or different.

[0258] Optionally, in some embodiments, when the second value comprises a frequency offset value or a cell offset value, by setting different second values for different second cells, the priority of the terminal switching to the second cell can be increased or decreased. Specifically, in some embodiments, when the triggering event comprises that the sum of the beam quality of the second beam and the second value is higher than a third threshold value, and / or the sum of the beam quality of the second beam and the second value is higher than the sum of the beam quality of the first beam and the first value by a fifth threshold value; at this time, if it is desired to increase the priority of the terminal switching to a certain second cell, the second value (such as a frequency offset value or a cell offset value) of the second cell can be set to a larger value, so that the sum of the beam quality of the second beam and the second value is larger, which can more easily be higher than the third threshold value, or more easily be higher than the sum of the beam quality of the first beam and the first value, so that the beam quality corresponding to the reference signal resource of the second cell is more likely to satisfy the triggering event, and the measurement reporting of the second cell is more likely to be triggered, thereby increasing the probability of the terminal switching to the second cell. Alternatively, if it is desired to decrease the priority of the terminal switching to a certain second cell, the second value (such as a frequency offset value or a cell offset value) of the second cell can be set to a smaller value, so that the sum of the beam quality of the second beam and the second value is smaller, which is not easy to be higher than the third threshold value, or not easy to be higher than the sum of the beam quality of the first beam and the first value, so that the beam quality corresponding to the reference signal resource of the second cell is not easy to satisfy the triggering event, and the measurement reporting of the second cell is not easy to be triggered, thereby decreasing the probability of the terminal switching to the second cell.

[0259] Alternatively, in some other embodiments, when the triggering event comprises: a difference between the beam quality of the second beam and the second value is higher than a fourth threshold value; and / or, the difference between the beam quality of the second beam and the second value is higher than the difference between the beam quality of the first beam and the first value by a sixth threshold value; if it is desired to increase the priority of the terminal switching to a second cell, the second value (e.g., a frequency offset value or a cell offset value) of the second cell can be set to a smaller value, so that the difference between the beam quality of the second beam and the second value is a larger value, which can more easily be higher than the fourth threshold value, or more easily be higher than the difference between the beam quality of the first beam and the first value, so that the beam quality corresponding to the reference signal resource of the second cell more easily satisfies the triggering event, the measurement reporting of the second cell can more easily be triggered, and thus the probability of the terminal switching to the second cell is increased. Alternatively, if it is desired to decrease the priority of the terminal switching to a second cell, the second value (e.g., a frequency offset value or a cell offset value) of the second cell can be set to a larger value, so that the difference between the beam quality of the second beam and the second value is a smaller value, which is not easy to be higher than the fourth threshold value, or not easy to be higher than the difference between the beam quality of the first beam and the first value, so that the beam quality corresponding to the reference signal resource of the second cell is not easy to satisfy the triggering event, the measurement reporting of the second cell is not easy to be triggered, and thus the probability of the terminal switching to the second cell is decreased.

[0260] Alternatively, in some other embodiments, when the triggering event comprises: a difference between the beam quality of the second beam and the second value is higher than a fourth threshold value; and / or, the difference between the beam quality of the second beam and the second value is higher than the difference between the beam quality of the first beam and the first value by a sixth threshold value; if it is desired to increase the priority of the terminal switching to a second cell, the second value (e.g., a frequency offset value or a cell offset value) of the second cell can be set to a smaller value, so that the difference between the beam quality of the second beam and the second value is a larger value, which can more easily be higher than the fourth threshold value, or more easily be higher than the difference between the beam quality of the first beam and the first value, so that the beam quality corresponding to the reference signal resource of the second cell more easily satisfies the triggering event, the measurement reporting of the second cell can more easily be triggered, and thus the probability of the terminal switching to the second cell is increased. Alternatively, if it is desired to decrease the priority of the terminal switching to a second cell, the second value (e.g., a frequency offset value or a cell offset value) of the second cell can be set to a larger value, so that the difference between the beam quality of the second beam and the second value is a smaller value, which is not easy to be higher than the fourth threshold value, or not easy to be higher than the difference between the beam quality of the first beam and the first value, so that the beam quality corresponding to the reference signal resource of the second cell is not easy to satisfy the triggering event, the measurement reporting of the second cell is not easy to be triggered, and thus the probability of the terminal switching to the second cell is decreased.

[0261] Optionally, in some embodiments, when the triggering event comprises: a difference between the beam quality of the second beam and the second value is higher than a fourth threshold value; and / or, the difference between the beam quality of the second beam and the second value is higher than the difference between the beam quality of the first beam and the first value by a sixth threshold value; if it is desired to increase the priority of the terminal switching to a certain second beam, the second value (such as the beam offset value) of the second beam can be set to a smaller value, so that the difference between the beam quality of the second beam and the second value is a larger value, which can be more easily higher than the fourth threshold value, or more easily higher than the difference between the beam quality of the first beam and the first value, so that the beam quality of the second beam is more easily satisfied to trigger the event, the measurement report of the second beam is more easily triggered, and the probability of the terminal switching to the second beam is increased. Alternatively, if it is desired to reduce the priority of the terminal switching to a certain second beam, the second value (such as the beam offset value) of the second beam can be set to a larger value, so that the difference between the beam quality of the second beam and the second value is a smaller value, which is not easy to be higher than the fourth threshold value, or not easy to be higher than the difference between the beam quality of the first beam and the first value, so that the beam quality of the second beam is not easy to satisfy the triggering event, the measurement report of the second beam is not easy to be triggered, and the probability of the terminal switching to the second beam is reduced.

[0262] Optionally, in some embodiments, the first report can comprise at least one of the following:

[0263] a measurement result of the first reference signal resource;

[0264] a resource identifier of the at least one second reference signal resource;

[0265] an event identifier (event ID) of the triggering event;

[0266] a report configuration identifier (reportconfig ID).

[0267] Optionally, the measurement result can comprise L1-RSRP and / or L1-SINR.

[0268] Optionally, the second reference signal resource can comprise: a reference signal resource of a second cell, and / or a reference signal resource having a QCL relationship with the reference signal resource of the second cell.

[0269] Optionally, the resource identifier can be used to indicate the reference signal resource, and in some embodiments, different second reference signal resources corresponding to the same second cell can correspond to different resource identifiers, and the second reference signal resources corresponding to different second cells can also correspond to different resource identifiers.

[0270] Optionally, when the second reference signal resource is an SSB resource, Table 1 shows a correspondence between a different second reference signal resource and an entry according to an embodiment of the present disclosure.

[0271] Table 1

[0272] As shown in Table 1, the second cell CellID#i corresponds to three second reference signal resources, which are SSB#n, SSB#n+1 and SSB#n+h respectively. Among them, the resource identification corresponding to SSB#n is "0", the resource identification corresponding to SSB#n+1 is "1", and the resource identification corresponding to SSB#n+h is "2". By analogy, assuming that each second cell corresponds to s second reference signal resources, the resource identifications corresponding to the s second reference signal resources of the first second cell can be 0-s-1 respectively, the resource identifications corresponding to the s second reference signal resources of the second second cell can be s-2s-1 respectively, the resource identifications corresponding to the s second reference signal resources of the third second cell can be 2s-3s-1 respectively, and so on.

[0273] It should be noted that the above is only an example description of the "correspondence between the reference signal resource and the resource identification", and other correspondences are also within the protection scope of the present disclosure, which is not limited by the present disclosure.

[0274] Optionally, in some embodiments, the network device can configure the triggering event to the terminal through radio resource control (RRC) configuration. Optionally, the above-mentioned correspondence between the second reference signal resource and the resource identification can also be configured by the network device through RRC, or the correspondence between the second reference signal resource and the resource identification can be agreed by the protocol.

[0275] Further, in some embodiments, the above-mentioned "beam" is only an example naming of the present disclosure, which can also be other names, for example, the beam can be called: 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 TCI state, DL TCI state, UL TCI state, unified TCI state, Common Transmission Configuration Indication state (common TCI state), spatial relation info, etc.

[0276] Step 2102, the terminal determines a triggering event.

[0277] Optionally, the terminal can receive a triggering event configured by the network device, or the terminal can determine the triggering event based on a protocol agreement.

[0278] For detailed description of the triggering event, please refer to the description of step 2101 above.

[0279] Step 2103, the beam quality of the first beam and / or the beam quality of the second beam meets the triggering event, and the terminal reports a first report.

[0280] For detailed description of step 2103, please refer to the description of step 2101 above.

[0281] Step 2104, the network device determines a target cell and / or a target beam of the terminal based on the first report.

[0282] Optionally, the first report can be used for LTM. That is, after receiving the first report, the network device can determine a second cell with better beam quality as a target cell of the terminal based on the measurement result of the first reference signal resource in the first report, and determine a beam corresponding to the first reference signal resource with better beam quality in the target cell as a target beam of the terminal in the target cell. Then, the network device can instruct the terminal to switch 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 a cell to which the terminal is about to switch, and the target beam can be understood as a beam to be used by the terminal after switching to the target cell.

[0283] Step 2105: The network device instructs the terminal to switch to the target cell and / or the target beam.

[0284] Step 2106: The terminal switches to the target cell and / or the target beam.

[0285] Optionally, after the terminal switches to the target cell and the target beam, the terminal can receive a downlink signal sent by the network device by using the target beam. In some embodiments, the terminal can also determine its corresponding uplink transmission beam based on the target beam, and send an uplink signal to the network device by using the uplink transmission beam.

[0286] In the above embodiment, the trigger event determined by the terminal can be used to trigger the first report of one or more cell reference signal resources. Therefore, the present disclosure defines a trigger event with different cells as granularity, which can trigger the first report of different cell reference signal resources, so that the trigger event of the present disclosure can be applied to the LTM scenario. When LTM is to be performed, the terminal can determine a trigger event by using the method of the present disclosure, and determine the reporting time of the measurement report of different candidate cells based on the trigger event. By flexibly setting the trigger event, the terminal can timely and accurately report the measurement report of the candidate cell at a suitable time, so as to avoid the situation that "the reporting interval configured by the network device is too short, so that the best beams of two reports are the same and do not change, thereby wasting signaling, and the reporting interval configured by the network device is too long, so that when the beam quality changes, the beam report is not sent due to not reaching the reporting time, thereby affecting the communication quality". Therefore, the signaling overhead and the time delay can be reduced, and the communication quality can be ensured when the beam quality changes.

[0287] In the above embodiments, the first value in the triggering event can be a frequency offset value of a frequency corresponding to the first cell, or can be a cell offset value corresponding to the first cell, or can be a beam offset value corresponding to the first beam; and the second value can be a frequency offset value of a frequency corresponding to the second cell, or can be a cell offset value corresponding to the second cell, or can be a beam offset value corresponding to the second beam. In this way, the different frequencies of the first cell correspond to different first values, or the different first cells correspond to different first values, or the different first beams of the first cell correspond to different first values, and the different frequencies of the second cell correspond to different second values, or the different second cells correspond to different second values, or the different second beams of the second cell correspond to different second values. By setting different first values and second values, different first cells can correspond to different triggering conditions, different second 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. In this way, the fairness of the first report triggering on different cells or different beams in a cell can be ensured; or the second values can be set for different second cells or different beams in a second cell, so that the possibility of the first report triggering on part of the second cells is higher, and the possibility of the first report triggering on another part of the second cells is lower, so that the terminal can switch to the second cell with a higher possibility of the first report triggering with a higher probability, thereby setting the second value to control the terminal to preferentially switch to a specific second cell, and improving the controllability of the communication. In a specific first cell, thereby setting the first value to control the terminal to switch to a specific first cell, and improving the controllability of the communication.

[0288] The determination method related to the embodiments of the present disclosure can include at least one of steps 2101 to 2106. For example, step 2101 can be implemented as an independent embodiment, step 2102 can be implemented as an independent embodiment, step 2103 can be implemented as an independent embodiment, and step 2101+S2102 can be implemented as an independent embodiment, but is not limited thereto.

[0289] In the present embodiment or example, each step can be independent, arbitrarily combined or exchanged in order, the optional mode or optional example can be arbitrarily combined, and can be arbitrarily combined with any step of other embodiments or other examples.

[0363] In some embodiments, the above-mentioned method can comprise the method described in the above-mentioned embodiments of the communication system side, the terminal side, the network device side, etc., which will not be repeated here.

[0364] The determination method related to the embodiments of the present disclosure can include at least one of steps 5101-5102. For example, step 5101 can be implemented as an independent embodiment, and step 5102 can be implemented as an independent embodiment, but is not limited thereto.

[0365] In the present embodiment or example, each step can be independent, arbitrarily combined or exchanged in order, the optional mode or optional example can be arbitrarily combined, and can be arbitrarily combined with any step of other embodiments or other examples.

[0366] The following is an exemplary introduction to the above method.

[0367] 1. The terminal determines an event (also referred to as a trigger condition), and sends a first report when a first reference signal resource satisfies the trigger condition of the event. The first reference signal resource is a reference signal resource corresponding to a current beam or a new beam in the event, wherein the reference signal resource corresponding to the new beam is a reference signal resource corresponding to a candidate cell, or a reference signal resource having a QCL relationship with the reference signal resource of the candidate cell.

[0368] a) The beam can be referred to as 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.

[0369] b) The first report is used for L1 / L2 triggered mobility

[0370] c) The candidate cell is a non-service cell of the terminal, and the candidate cell is used to determine a cell as a target cell, i.e., a cell to which the terminal will be handed over.

[0371] 2. Based on 1, when the first reference signal resource is used to determine the new beam, the first reference signal resource can be SSB or CSI-RS

[0372] a) The PCI corresponding to the SSB is the PCI of the candidate cell

[0373] b) CSI-RS has QCL relationship with SSB of candidate cell

[0374] 3. Based on 1, candidate cell is intra-frequency with terminal's serving cell, i.e. same frequency, or inter-frequency with terminal's serving cell, i.e. different frequency.

[0375] 4. Based on 3, the event includes

[0376] a) current beam quality and one frequency related first offset sum or difference is lower than threshold

[0377] i. Where quality can be L1-RSRP, L1-SINR, such as

[0378] 1. Ms + offset(f) < threshold1

[0379] Where offset(f) is related to frequency, such as if the event is to trigger measurement of candidate cell of frequency f1, then offset value is offset(f1); if the event is to trigger measurement of candidate cell of f2, then offset value is offset(f2). offset(f1) and offset(f2) can be different values, or same value. If candidate cell is intra-frequency with current serving cell, then offset(f) can take value of 0 or candidate cell's offset(f) is same as serving cell's offset(f), such as in the event given in c) i.e. both offset(f) are same. And / or if inter-frequency with current serving cell, then offset(f) takes value other than 0 and same value for different frequencies.

[0380] b) new beam quality and one frequency related second offset sum or difference is higher than threshold

[0381] i. New beam is also called target beam

[0382] 1. Mn + offset(fn) > threshold2

[0383] where offset(f) is frequency dependent, e.g. if the event is to determine whether a beam of a candidate cell of frequency f1 is better, then the offset value is offset(f1); if the event is to determine whether a beam of a candidate cell of frequency f2 is better, then the offset value is offset(f2). offset(f1) and offset(f2) can be different values, or the same value. offset(f) can take value 0 if the candidate cell is on the same frequency as the current serving cell. And / or offset takes value not 0 if on different frequency, and the different frequencies take the same value.

[0384] c) the sum or difference of the new beam and one offset related to frequency is higher than the current beam quality by a threshold

[0385] i. Mn+offset(fn) > Ms+offset(fs)+threshold3

[0386] where offset(f) is frequency dependent, e.g. if the event is to determine whether a beam of a candidate cell of frequency f1 is better than the current beam, then the offset value is offset(f1); if the event is to determine whether a beam of a candidate cell of 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. offset(f) can take value 0 if the candidate cell is on the same frequency as the current serving cell. And / or offset takes value not 0 if on different frequency, and the different frequencies take the same value.

[0387] Note: further, each of the above events can also contain a cell specific offset and a beam specific offset.

[0388] 5. Based on 4, the event is based on base station RRC configuration or protocol agreement

[0389] 6. Based on 1, the current beam is determined based on indicated TCI state, or activated indicated TCI state

[0390] a) i.e. the reference signal resource corresponding to the current beam is the reference signal resource indicated by the indicated TCI state, or activated indicated TCI state, if there are two reference signal resources, then the reference signal resource corresponding to QCL Type D.

[0391] 7. Based on 1, the first report includes the entry of reference signal identification corresponding to the new beam in the list configured by the base station RRC.

[0392] The entry of reference signal identification corresponding to the new beam is shown in the following table.

[0393] The above is just an example, that is, the reference signal entry of the first cell is numbered in order 0~s-1, and each cell corresponds to s reference signal identifications; then the reference signal entry of the second cell is s~2s-1, the reference signal entry of the third cell is 2s~3s-1, and so on.

[0394] 8. Based on 7, the first report contains at least the entry of the reference signal of the candidate cell.

[0395] The first report can also contain the event ID.

[0396] In the disclosure, by proposing a definition method of the event triggering the beam report when the L1 / L2 triggering mobility is used, the timeliness and accuracy of triggering the beam report on different frequencies are ensured.

[0397] The embodiments of the disclosure also propose a device for implementing any of the above methods, for example, a device is proposed, which includes units or modules for implementing each step performed by the terminal in any of the above methods. For another example, another device is also proposed, which includes units or modules for implementing each step performed by the network equipment (such as an access network device, a core network function node, a core network device, etc.) in any of the above methods.

[0398] It should be understood that the division of each unit or module in the above apparatus is only a logical function division, and all or part of them can be integrated into a physical entity or physically separated in actual implementation. In addition, the units or modules in the apparatus can be implemented in the form of processor calling software: for example, the apparatus includes a processor, the processor is connected with a memory, the memory stores instructions, and the processor calls the instructions stored in the memory to realize the functions of any of the above methods or the units or modules of the above apparatus, wherein the processor is a general processor such as a central processing unit (CPU) or a microprocessor, and the memory is a memory in the apparatus or a memory outside the apparatus. Alternatively, the units or modules in the apparatus can be implemented in the form of hardware circuit, and the functions of part or all of the units or modules can be realized by the design of the hardware circuit. The above hardware circuit can be understood as one or more processors; for example, in one implementation, the above hardware circuit is an application-specific integrated circuit (ASIC), and the functions of part or all of the units or modules are realized by the design of the logical relationship between the elements in the circuit; for another example, in another implementation, the above hardware circuit is a programmable logic device (PLD), and a field programmable gate array (FPGA) is taken as an example, which can include a large number of logic gate circuits, and the connection relationship between the logic gate circuits is configured by a configuration file, so as to realize the functions of part or all of the units or modules. All units or modules of the above apparatus can be all implemented in the form of processor calling software, or all implemented in the form of hardware circuit, or part implemented in the form of processor calling software and the remaining part implemented in the form of hardware circuit.

[0399] In the embodiments of the present disclosure, the processor is a circuit with signal processing capability. In one implementation, the processor can be a circuit with instruction reading and running capability, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), a digital signal processor (DSP), or the like. In another implementation, the processor can implement certain functions through a logical relationship of hardware circuits, and the logical relationship of the hardware circuits is fixed or can be reconfigured. For example, the processor is a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as an FPGA.
