As shown in Figure 1, the communication system 100 may include a terminal and a network device. Optionally, the network device may include at least one of an access network device and a core network device.

In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0320] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit. The CU-DU structure can be used to split the protocol layer of the access network device, with the functions of some protocol layers centrally controlled by the CU, and the functions of the remaining part or all of the protocol layers distributed in the DU, which is centrally controlled by the CU, but is not limited to this.

[0323] The following embodiments of the present disclosure may be applied to the communication system 100 shown in Figure 1, or a portion thereof, but are not limited thereto. The entities shown in Figure 1 are illustrative only. The communication system may include all or part of the entities shown in Figure 1, or may include other entities outside of Figure 1. The number and form of the entities may be arbitrary. The connection relationship between the entities is illustrative only.

[0324] The 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), 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 (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 utilizing other determination methods, and next-generation systems based on and extending these systems. Furthermore, a combination of multiple systems (e.g., a combination of LTE or LTE-A with 5G) may also be employed.

[0325] Optionally, in a communication system, when a terminal reports a beam report to a network device, the network device usually first configures the reporting timing of the beam report to the terminal, and then the terminal reports the beam report based on the reporting timing configured by the network device. Optionally, the network device usually configures the terminal to report the beam report periodically, semi-persistently, or aperiodically. However, in reality, the change in beam quality is what the terminal can learn most promptly, and the reporting timing configured by the network device (such as the period length of periodic reporting or the aperiodic reporting timing) is not necessarily the most appropriate. For example, if the reporting interval is too short, the best beam reported twice may be the same without change, thereby 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 arrived", thereby affecting the communication quality. Based on this, in order to determine the accurate reporting timing, a method of triggering beam reports based on beam groups by events is proposed. However, how to determine the event used to trigger beam reports based on beam groups is currently unclear.

[0326] FIG2A is an interactive diagram illustrating a determination method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a determination method for a communication system 100, the method comprising:

[0327] Step 2101: A network device configures a triggering event.

[0328] Optionally, in some embodiments, the trigger event can be used to trigger a beam report based on a beam group. Optionally, the beam group can include at least two beams. Optionally, the above-mentioned "trigger event is used to trigger a beam report based on a beam group" can be understood as: when the beam group meets the trigger event, the terminal triggers the beam report (that is, the terminal reports the beam report to the network device), and the beam report may include the beam measurement results of the terminal for the beams in the beam group, and the network device can schedule beams with high beam quality for channel and / or signal transmission and reception based on the beam measurement results in the beam report. Optionally, the channel may include a physical downlink control channel (PDCCH), a physical downlink shared channel (PDSCH), a physical uplink shared channel (PUSCH), and a physical uplink control channel (PUCCH); the signal may include a channel state information reference signal (CSI-RS) and a sounding reference signal (SRS).

[0329] Optionally, in some embodiments, the triggering event may refer to an event in which "the beam quality of the terminal changes". Optionally, the triggering event may include, for example, at least one of the following:

[0330] The beam quality of the first beam group is lower than a first threshold value; wherein the first beam group may be the beam group in the last beam report of the terminal and / or the beam group currently used by the terminal; optionally, the first beam group may include at least one of the following: the best beam group in the last beam report, the beam group most recently indicated by the network device, the beam group most recently activated by the network device, all beam groups in the last beam report, and the worst beam group in the last beam report;

[0331] The beam quality of the second beam group is higher than a second threshold value; the second beam group may be a candidate beam group, and optionally, the second beam group may include at least one of the following: a non-optimal beam group in a previous beam report, a beam group other than a beam group in a previous beam report, a beam group other than a beam group recently indicated by the network device, and a beam group other than at least one beam group recently activated by the network device;

[0332] A difference between the beam quality of the second beam group and the beam quality of the first beam group is greater than or equal to a third threshold value;

[0333] The current best K beam groups of the terminal are different from at least one of the best K beam groups in the terminal's last beam report, where K is a positive integer;

[0334] The current best K beam groups of the terminal do not include the best K beam groups in the last beam report;

[0335] The terminal's current best K beam groups do not include the beam group most recently indicated by the network device;

[0336] The terminal's current best K beam groups do not include the beam group most recently activated by the network device;

[0337] The difference between the beam quality of the terminal's current best-ranked i-th beam group and the beam quality of the best-ranked j-th beam group in the last beam report is greater than or equal to a fourth threshold, where i and j are positive integers, i is less than or equal to K, and j is less than or equal to K;

[0338] The difference between the beam quality of the current worst beam group of the terminal and the beam quality of the worst beam group in the last beam report is greater than or equal to the fifth threshold.

[0339] Optionally, the beam quality of the beam group mentioned in the above triggering event can be determined based on the beam qualities of the beams included in the beam group; in some embodiments, the beam quality of the beam group can be the average of the beam qualities of at least two beams in the beam group; in other embodiments, the beam quality of the beam group can be the weighted average of the beam qualities of at least two beams in the beam group, for example, different weights can be set for each beam in the beam group, wherein the sum of the weights of each beam in the beam group is 1, and the beam quality of each beam in the beam group can be calculated. The product of the beam quality and the corresponding weight is used to obtain a weighted value of the beam quality of each beam. Subsequently, the weighted values ​​of the beam qualities of the various beams are averaged to obtain the beam quality of the beam group. For example, assuming that the weight of a beam in the beam group may be 1, and the weights of the other beams may be 0, for example, the weight of the beam with the highest beam quality in the beam group may be set to 1, or the weight of the beam with the lowest beam quality in the beam group may be set to 1. In this case, when the beam group includes only two beams, the beam quality of the beam group is the beam quality corresponding to the beam with a weight of 1. Alternatively, in some other embodiments, the beam quality of the beam group may be the sum of the beam qualities of at least two beams in the beam group and a first value, where the first value may be the product of the beam qualities of the at least two beams in the beam group. For example, the beam quality of the beam group can be calculated according to the Shannon capacity formula. Optionally, assuming that the beam group includes two beams, beam #1 and beam #2, the Shannon capacity formula can be, for example: Log 2(1+a)=log2(1+b)+log2(1+c), where a is the beam quality of the beam group, b is the beam quality of beam #1 in the beam group, and c is the beam quality of beam #2 in the beam group. After converting the above Shannon capacity formula, it can be obtained: Log 2(1+a)=log2((1+b)×(1+c)), then (1+a)=(1+b)×(1+c), which can be simplified to yield: a=b+c+b×c, i.e., the beam quality of the beam group is the sum of the beam quality of beam #1, the beam quality of beam #2, and the first value in the beam group, where the first value is the product of the beam quality of beam #1 and the beam quality of beam #2.

[0340] Optionally, the beam quality may be, for example, a layer 1 reference signal received power (Layer 1 Reference Signal Received Power, L1-RSRP) and / or a layer 1 signal to interference plus noise ratio (Layer 1 Signal to Interference plus Noise Ratio, L1-SINR).

[0341] Optionally, the above-mentioned "beam group recently indicated by the network device" can be, for example,: the beam group recently indicated by the network device using downlink control information (DCI) signaling; optionally, the above-mentioned "beam group recently activated by the network device" can be, for example,: the beam group recently activated by the network device using medium access control layer control element (MAC CE) signaling. Specifically, in some embodiments, the network device usually first activates at least one TCI state corresponding to at least one code point in the indication field of the DCI signaling (such as the Transmission Configuration Indication (TCI) indication field) through MAC CE signaling. When MAC CE signaling activates at least one TCI state corresponding to a code point, the terminal can directly use the beam corresponding to the at least one TCI state corresponding to the activated code point to transmit and receive channels and / or signals; when MAC CE signaling activates at least one TCI state corresponding to multiple code points, the network device also needs to indicate one of the multiple activated code points through DCI signaling. After that, the terminal can transmit and receive channels and / or signals based on the beam corresponding to the at least one TCI state corresponding to the code point indicated by the DCI signaling. Based on this, in some embodiments, the above-mentioned "beam group recently indicated by the network device" can be, for example, the beam group corresponding to the TCI state corresponding to the code point recently indicated by the network device using DCI signaling, and the above-mentioned "beam group recently activated by the network device" can be, for example, the beam group corresponding to the TCI state corresponding to the code point recently activated by the network device using MAC CE signaling. Among them, the channel may include PDCCH, PDSCH, PUSCH, PUCCH; the signal may include CSI-RS, SRS. The TCI state may include at least one of joint TCIstate, DL (downlink) TCIstate, UL (uplink) TCIstate, TCIstate, and spatialrelationinfo.

[0342] Optionally, in some embodiments, the method for configuring a trigger event for a network device may be, for example: the network device sends first information, where the first information may indicate the trigger event.

[0343] In some other embodiments, the method for configuring a trigger event by a network device may include: the network device sends a first signaling, where the first signaling may be used to configure the trigger event. Optionally, the first signaling may be a Radio Resource Control (RRC) signaling.

[0344] In some further embodiments, the method for configuring a trigger event by a network device may include, for example, sending a first signaling and a second signaling, wherein the first signaling may be used to configure at least one trigger event, and the second signaling may be used to activate or trigger a trigger event in the at least one trigger event configured by the first signaling. Optionally, the first signaling may be, for example, RRC signaling, and the second signaling may be, for example, DCI signaling and / or MAC CE signaling.

[0345] Optionally, the method for configuring at least one trigger event by the above-mentioned first signaling may include: the first signaling may configure at least one of the following: at least one association relationship, an association sequence number (Identity, ID) corresponding to the association relationship, a beam reporting type, a beam reporting method, and beam group related information; wherein the association relationship may include: an association relationship between a beam group, a trigger event corresponding to the beam group, and a beam measurement quantity corresponding to the beam group, or the association relationship may, for example, be: an association relationship between a reference signal resource or a reference signal resource set corresponding to a beam in the beam group, a trigger event corresponding to the reference signal resource or the reference signal resource set, and a beam measurement quantity corresponding to the reference signal resource or the reference signal resource set. Optionally, the reference signal resource or the reference signal resource set may, for example, be a channel measurement resource (CMR) and / or an interference measurement resource (IMR), wherein the reference signal resource or the reference signal resource in the reference signal resource set may be periodically transmitted, semi-persistently transmitted, or aperiodically transmitted. Optionally, the above-mentioned beam measurement quantity may be, for example, L1-RSRP and / or L1-SINR. Optionally, when a beam group is associated with a trigger event and a beam measurement quantity, the terminal may measure the beams in the beam group based on the beam measurement quantity to obtain a beam measurement result, and when the beam measurement result meets the trigger event associated with the beam group, a beam report based on the beam group is triggered, and the beam report may include the beam measurement result.

[0346] Optionally, the above-mentioned beam reporting type may include: semi-persistent reporting and aperiodic reporting. In addition, the terminal may subsequently perform beam reporting based on the beam reporting type configured by the network device.

[0347] Optionally, the aforementioned beam reporting methods may include: beam reporting based on beam groups and beam reporting not based on beam groups. Optionally, "beam reporting based on beam groups" may be understood, for example, as reporting the beam quality of beam groups on a per-beam basis; and "beam reporting not based on beam groups" may be understood, for example, as reporting the beam quality of beams on a per-beam basis. Furthermore, the terminal may subsequently perform beam reporting based on the beam reporting method configured by the network device.

[0348] Optionally, the above-mentioned beam group related information can be used to indicate the purpose of at least two beams in the beam group, and the purpose may include at least one of the following: used for the terminal to perform uplink transmission simultaneously, and used for the terminal to perform downlink reception simultaneously.

[0349] It should be noted that in some embodiments, the above-mentioned beam reporting method and beam group related information may not be configured by the network device to the terminal, but may be determined autonomously by the terminal and then reported to the network device.

[0350] Optionally, the method in which the above-mentioned second signaling is used to activate or trigger a trigger event in at least one trigger event configured by the first signaling may include: the second signaling is used to indicate the association ID corresponding to the above-mentioned association relationship to activate or trigger the trigger event configured by the first signaling. For example, assuming that the association relationships configured by the first signaling include: association relationship #1: the association relationship between beam group #1, trigger event #1 corresponding to beam group #1, and beam measurement quantity #1 corresponding to beam group #1, and the association ID corresponding to association relationship #1 is 1; association relationship #2: the association relationship between beam group #2, trigger event #2 corresponding to beam group #2, and beam measurement quantity #2 corresponding to beam group #2, and the association ID corresponding to association relationship #2 is 2. Assuming that the association ID indicated by the second signaling is 2, it means that the network device has activated or triggered association relationship #2. At this time, the terminal can measure the beam in beam group #2 based on beam measurement quantity #2 (that is, measure the L1-RSRP and / or L1-SINR of the beam in beam group #2 to obtain the beam measurement result), and when the beam measurement result of beam group #2 meets the trigger event #2, the terminal performs a beam report based on beam group #2.

[0351] It should be noted that in some embodiments, when the second signaling is DCI signaling, the channel state information (CSI) request (request) field in the DCI signaling can be directly multiplexed or extended to activate or trigger at least one trigger event in the first signaling configuration. For example, the CSI request field in the DCI signaling can be directly multiplexed to indicate the association ID, or the CSI request field in the DCI signaling can be extended to indicate the association ID.

[0352] Step 2102: The terminal determines a triggering event.

[0353] For a detailed introduction to the triggering events, please refer to the above step description.

[0360] Optionally, in some embodiments, the third information can be used to configure a first request, the first request can be used to request a first resource, and the first resource can be used to carry a beam report. Optionally, the first request can be, for example, a scheduling request (SR), and the first resource can be, for example, a physical uplink shared channel (PUSCH) resource.

[0361] Optionally, the above-mentioned “the third information is used to configure the first request” can be understood as: the third information is used to configure the time-frequency resources, sequence, etc. of the first request.

[0362] Optionally, the network device may send the third information to the terminal, and the terminal may receive the third information.

[0363] Step 2104: The terminal sends a first request.

[0364] Optionally, the terminal may send the first request based on the third information mentioned above.

[0365] Optionally, the first request may be sent when the terminal determines that the beam group meets the triggering event.

[0366] Step 2105: The network device configures the first resource.

[0367] Step 2106: The terminal determines that the trigger event is met and reports at least one beam report.

[0368] Optionally, when the terminal determines that the beam group meets the triggering event, the terminal reports at least one beam report. Optionally, the terminal may carry the beam report through the first resource to report the beam report.

[0369] Optionally, in some embodiments, when a terminal reports multiple beam reports, the terminal may determine the time interval between two adjacent beam reports, and report the multiple beam reports based on the time interval. Optionally, the time interval may be configured by a network device to the terminal, such as by the network device through at least one of the above-mentioned first information, first signaling, and second signaling. Alternatively, the network device may also configure the time interval through signaling other than the above-mentioned first information, first signaling, and second signaling. Alternatively, the time interval may also be predefined by a protocol.

[0370] Optionally, in some embodiments, the beam report may include at least one of the following:

[0371] The beam quality of the beam corresponding to the terminal's serving cell;

[0372] The beam quality of the beam corresponding to the cell other than the serving cell of the terminal (for example, the neighboring cell).

[0373] Optionally, when the beam report includes the beam quality of the beam corresponding to the cell other than the service cell of the terminal, the beam report may also include the physical cell identifier (PCI) of the cell other than the service cell of the terminal, wherein the PCI may be configured to the terminal by the network device, such as the network device configures it to the terminal through at least one of the above-mentioned first information, first signaling, and second signaling, or the network device may also configure the PCI through signaling other than the above-mentioned first information, first signaling, and second signaling.

[0374] Optionally, in some embodiments, when the beam reporting mode is beam reporting based on a beam group, the beam report may include at least one of the following:

[0375] Second information, where the second information is used to indicate the number of reported beam groups;

[0376] The resource identifier of the reference signal resource corresponding to the beam in each reported beam group;

[0379] Fourth information, the fourth information is used to indicate the number of reported beams;

[0380] The resource identifier of the reference signal resource corresponding to each reported beam;

[0381] Beam quality of each beam.

[0382] In the above embodiment, the terminal will determine the triggering event for triggering the beam report based on the beam group. It can be seen that the present disclosure provides a determination method to determine the triggering event for triggering the beam report based on the beam group, so that the beam report can be performed in time when the beam quality changes based on the triggering event, thereby avoiding the situation where "the beam reporting interval configured by the network device is too short, which may make the best beams reported twice the same and unchanged, thereby wasting signaling, and the beam reporting interval configured by the network device is too long, which may cause the beam quality to change. The beam report is not performed because the reporting time has not arrived, thereby affecting the communication quality." The method of the present disclosure can reduce signaling overhead, and can also ensure that when the beam quality changes, it can be reported in time to ensure communication quality. On the premise of reducing signaling overhead, the accuracy and timeliness of the beam report based on the beam group are also guaranteed.

[0544] 1. The best beam group in the last report, or the beam group most recently indicated by the base station, or all beam groups activated by the base station MAC CE, or all beam groups in the last report, or the worst beam group in the last report

[0545] b) The beam quality of the candidate beam group is higher than the threshold

[0546] i. The candidate beam group is defined as: the non-optimal beam group in the last report, the beam group other than the beam group included in the last report, or the beam group most recently indicated by the base station, or at least one beam group activated by the base station MAC CE

[0547] c) The beam quality of the candidate beam group is one offset higher than the beam quality of the current group

[0548] i. The definitions of the current beam group and candidate beam group are the same as above

[0550] i. Furthermore, the difference in beam quality between the best beam groups in the two reports is greater than offset

[0551] ii. Or the difference in beam quality between the worst beam groups in the two reports is greater than offset

[0552] 3. The beam quality of a beam group is determined based on the beam qualities of the two beams within the beam group. The specific details are as follows:

[0553] a) Average L1-RSRP or L1-SINR corresponding to the two beams in the beam group

[0554] b) Weighted average of L1-RSRP or L1-SINR corresponding to the two beams in the beam group

[0555] i. For example, if one of the L1-RSRP or L1-SINR accounts for a larger proportion, the proportion can be 1, that is, directly a larger L1-RSRP or L1-SINR value, or a smaller one.

[0556] c) Determine the L1-SINR of beam group according to the Shannon capacity formula: Log 2(1+SINR-group)=log 2(1+SINR#1)+log 2(1+SINR#2), where SINR#1 and SINR#2 are the L1-SINRs of the two beams of beam group, respectively.

[0557] 4. The instruction information includes at least one of the following:

[0560] i. Specifically, an association relationship can also be configured during RRC configuration, such as the trigger event and the related threshold or offset and the reference signal resource or resource set (including CMR and / or IMR, the reference signal resource can be a reference signal resource that is sent periodically, semi-persistently, or aperiodically), the association with the reported measurement quantity L1-RSRP or L1-SINR, the reporting type (semi-persistent, or aperiodic transmission report), the reporting method (whether it is a group-based beam report, is it used for simultaneous uplink transmission, and / or simultaneous downlink reception. This can be configured by the base station, or the terminal reports it by itself), and an associated ID. Then, the MAC CE or DCI can directly activate or indicate the ID. If it is indicated by DCI, the CSI request field can be directly reused or extended.

[0561] 5. After the trigger condition is met, you can report once or multiple times, and configure the time interval between each report

[0562] 6. The beam report may include the beam value of the serving cell, or cells other than the serving cell, such as neighboring cells, whose physical cell ID PCI will be configured for the terminal.
