[0031] In the above embodiment, after the first terminal generates indication information based on the coordinated multiple listening opportunities, it can send the indication information corresponding to the second terminal to the second terminal. Since the coordinated multiple listening opportunities do not conflict, the probability of the first terminal sending the first information to the second terminal at the listening opportunity indicated by the indication information corresponding to the second terminal will be relatively high (relative to the listening opportunity before adjustment). Therefore, after the second terminal determines the listening opportunity based on the indication information, it monitors the first information according to the listening opportunity indicated by the second indication information, which is beneficial to increase the probability of the second terminal receiving the first information, so as to reduce the overhead of the second terminal monitoring the first information.

The network element 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).

[0091] In some embodiments, the technical solution of the present disclosure can be applied to the Open RAN architecture. 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.

[0092] 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.

[0093] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0094] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0095] 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 communication methods, and next-generation systems based on and extending these methods. Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0096] In some embodiments, in a scenario where a first terminal communicates with a second terminal through a sidelink, the first terminal can receive a beam transmitted by the second terminal. In the event of a beam failure, the first terminal can perform beam failure recovery (BFR). For example, the first terminal can send a beam failure request (BFR Request, BFRR) to the second terminal.

[0097] Unlike the scenario where the terminal communicates with the network device in a mobile network, the network device generally does not have mobility, but the terminal has mobility. Therefore, in the scenario where the first terminal receives the beam transmitted by the second terminal, both the first terminal and the second terminal can be mobile, so the first terminal can be within the signal coverage range of multiple second terminals, and the signal coverage range of the second terminal can also include multiple first terminals. Therefore, the first terminal, as a receiving end, can receive beams transmitted by multiple second terminals as transmitting ends, and the second terminal, as a transmitting end, can transmit beams to multiple first terminals as receiving ends.

[0098] For the second terminal, in the scenario of transmitting beams to multiple first terminals, beam failure may occur to each first terminal. Therefore, the second terminal needs to configure resources for sending beam failure requests for each first terminal. This resource is also the time for the second terminal to listen to the beam failure request sent by the first terminal.

[0099] Since the beams used by the second terminal to communicate with each first terminal may be different, it is generally not possible to monitor beam failure requests sent by multiple first terminals on the same resource. Therefore, the resources configured by the second terminal for sending beam failure requests for different first terminals may be different in the time domain.

[0100] FIG2 is a schematic diagram showing a monitoring opportunity according to an embodiment of the present disclosure.

[0101] Taking the communication between the second terminal and three first terminals as an example, the three first terminals are UE#1, UE#2 and UE#3 respectively. The second terminal can configure resources for sending beam failure recovery requests for each first terminal respectively, for example, the resources can be periodic.

[0102] For example, as shown in Figure 2, a cycle may include three time periods T1, T2, and T3. Within a cycle, the resources for UE#1 to send a beam failure recovery request are within the T1 time period, the resources for UE#2 to send a beam failure recovery request are within the T2 time period, and the resources for UE#3 to send a beam failure recovery request are within the T3 time period. Since the three time periods T1, T2, and T3 do not overlap, it can ensure that the second terminal can receive the beam failure recovery requests sent by UE#1, UE#2, and UE#3 in the three time periods T1, T2, and T3, respectively.

[0103] However, in some embodiments, beam failure is random, and the second terminal cannot determine in which specific period the beam failure of the first terminal will occur and report the beam failure recovery request. In order to ensure that the beam failure recovery request sent by the first terminal can be successfully monitored, the second terminal needs to continue monitoring during the monitoring opportunity of each period.

[0104] FIG3 is a schematic diagram showing another monitoring opportunity according to an embodiment of the present disclosure.

[0105] As shown in Figure 3, based on the embodiment shown in Figure 2, within each cycle, the second terminal needs to monitor three beam failure recovery requests sent by the first terminal. However, this continuous monitoring incurs significant overhead. Unlike network devices, terminals have relatively low battery life and processing capabilities, so this continuous monitoring places a significant burden on these capabilities.

[0106] Moreover, in some embodiments, the first terminal, as a receiving end, can receive a scenario in which multiple beams are transmitted by second terminals, as transmitting ends, and the resources for sending beam failure recovery requests configured by different second terminals for the first terminal may conflict.

[0107] FIG4 is a schematic diagram showing another monitoring opportunity according to an embodiment of the present disclosure.

[0108] For example, a first terminal receives beams transmitted by three second terminals, UE#A, UE#B, and UE#C. The three second terminals can each configure resources for sending beam failure recovery requests to the first terminal, for example, the resources can be periodic.

[0109] As shown in Figure 4, the period of resources configured by UE#A for the first terminal is 3T, which are T1, T2 and T3 respectively, and the monitoring time is T2; the period of resources configured by UE#B and UE#C for the first terminal is 2T, which are T1 and T2 respectively, and the monitoring time is T1.

[0110] It can be seen that in the first cycle, UE#B and UE#C have a conflicting listening opportunity for the first terminal to send a beam failure recovery request. In the second cycle, UE#A, UE#B and UE#C have a conflicting listening opportunity for the first terminal to send a beam failure recovery request.

[0111] A first terminal can use a different beam when communicating with each second terminal. Therefore, it generally does not simultaneously send beam failure recovery requests to multiple second terminals during conflicting monitoring opportunities. Therefore, when beam failure recovery requests configured by multiple second terminals conflict, the first terminal can only send a beam failure recovery request to one second terminal using a single resource.

[0112] In this case, if each second terminal monitors the beam failure recovery request sent by the first terminal during the periodic monitoring opportunity, it will cause a huge overhead for each second terminal.

[0113] FIG5 is an interactive schematic diagram showing a method for sending an indication according to an embodiment of the present disclosure.

[0114] As shown in FIG5 , the instruction sending method includes:

[0115] In step S501, the first terminal determines that multiple monitoring opportunities corresponding to multiple second terminals conflict, and determines multiple coordinated monitoring opportunities, wherein the multiple coordinated monitoring opportunities do not conflict.

[0116] In some embodiments, the first terminal may generate indication information corresponding to each second terminal according to the coordinated multiple monitoring opportunities.

[0117] In step S502, the first terminal may send indication information corresponding to the second terminal to the second terminal, wherein the indication information corresponding to the second terminal is used to instruct the second terminal to determine the adjusted monitoring opportunity corresponding to the second terminal.

[0118] In some embodiments, the monitoring opportunity corresponding to the second terminal is used by the second terminal to monitor the first information sent by the first terminal.

[0119] In some embodiments, the first information includes at least one of the following:

[0120] Beam failure recovery request;

[0121] Hybrid Automatic Repeat reQuest (HARQ) information, such as Hybrid Automatic Repeat reQuest Acknowledgement (HARQ-ACK) and Hybrid Automatic Repeat reQuest Negative ACK (HARQ-NACK).

[0122] It should be noted that the first information is not limited to beam failure recovery request and hybrid automatic repeat request information, but can also be information with the above-mentioned technical problems when sent by other first terminals to the second terminals. This disclosure does not limit this.

[0123] The above embodiments mainly describe the technical problems that exist when the first terminal sends a beam failure recovery request to the second terminal. Similar technical problems also exist when the first terminal sends hybrid automatic repeat request information to the second terminal. The causes of the two technical problems are similar and will not be repeated here.

[0124] The main difference between the two is that a beam failure recovery request is sent by the second terminal using the resources configured for the first terminal to send the beam failure recovery request, while a hybrid automatic repeat request message is sent by the second terminal using the resources configured for the first terminal to send the hybrid automatic repeat request message. The following embodiments illustrate the technical solution of the present disclosure primarily when the first message is a beam failure recovery request.

[0125] In an embodiment of the present disclosure, a first terminal can communicate with multiple second terminals, and each second terminal can configure resources for sending first information to the first terminal respectively. The resources can also be called listening opportunities for the second terminals. Since each second terminal listens to the first information at its corresponding listening opportunity, the first terminal can determine multiple listening opportunities.

[0126] When the first terminal determines that multiple monitoring opportunities conflict, the first terminal may coordinate the multiple monitoring opportunities to ensure that the coordinated multiple monitoring opportunities do not conflict. Examples of the coordination operation are not described here and will be illustrated in subsequent embodiments.

[0127] Furthermore, the first terminal can generate indication information based on the multiple listening opportunities after coordination. Since the multiple listening opportunities after coordination may have changed for each second terminal relative to the multiple listening opportunities before coordination, multiple indication information can be generated, and the indication information domain and the second terminal are one-to-one corresponding, so that the second terminal can accurately determine the coordinated listening opportunity based on the indication information.

[0128] According to an embodiment of the present disclosure, after the first terminal generates indication information based on multiple coordinated listening opportunities, it can send the indication information corresponding to the second terminal to the second terminal. Since the multiple coordinated listening opportunities do not conflict, the probability of the first terminal sending the first information to the second terminal at the listening opportunity indicated by the indication information corresponding to the second terminal will be relatively high (relative to the listening opportunity before adjustment). Therefore, after the second terminal determines the listening opportunity based on the indication information, it monitors the first information according to the listening opportunity indicated by the second indication information, which is beneficial to increase the probability of the second terminal receiving the first information, so as to reduce the overhead of the second terminal monitoring the first information.

[0129] In some embodiments, the indication sending method further includes: sending the first information to the second terminal at the adjusted monitoring opportunity corresponding to the second terminal.

[0130] After the first terminal sends the adjusted listening opportunity corresponding to the second terminal to the second terminal, it can send the first information to the second terminal at the adjusted listening opportunity corresponding to the second terminal, so that the second terminal can monitor the first information sent by the terminal at the adjusted listening opportunity corresponding to the second terminal.

[0131] In some embodiments, the listening opportunity comprises a periodic listening opportunity.

[0132] In some embodiments, the indication information corresponding to the second terminal is used to indicate whether the second terminal is available at a listening opportunity in a plurality of listening cycles of the second terminal.

[0133] For example, taking the first information as a beam failure recovery request as an example, the monitoring timing of the second terminal monitoring the first terminal sending a beam failure recovery request can be periodic, and a monitoring period can include a monitoring timing, for example, the monitoring timing occupies part or all of the duration of the monitoring period.

[0134] Before the adjustment, the listening opportunity is available in each listening cycle, but as shown in Figure 4, there may be a conflict in the listening opportunities of different second terminals. The first terminal coordinates multiple listening opportunities, which may include determining that the listening opportunities in some listening cycles are unavailable. The first indication information can indicate to the second terminal which listening opportunities in multiple listening cycles are available and which listening opportunities are unavailable.

[0135] Therefore, the second terminal can monitor the first information only at available monitoring opportunities, without having to monitor the first information at unavailable monitoring opportunities. Accordingly, compared with the second terminal monitoring information according to the monitoring opportunities before coordination, the overhead of the second terminal monitoring the first information is reduced.

[0136] In some embodiments, the indication information corresponding to the second terminal includes multiple bits.

[0137] In some embodiments, the number of the plurality of bits is equal to the number of a plurality of listening periods of the second terminal and corresponds to the plurality of listening periods of the second terminal.

[0138] In some embodiments, a first bit among the plurality of bits indicates whether a listening opportunity in a listening period corresponding to the first bit is available to the second terminal.

[0139] In some embodiments, the listening timing of the second terminal to listen to the first information can be periodic, and the second terminal will listen to the first information at the listening timing of a certain number of listening periods, so the indication information sent by the first terminal to the second terminal can be indicated based on the number of listening periods, so that the second terminal can accurately determine whether to listen to the first information within the listening timing of each listening period.

[0140] For example, if the number of monitoring periods of the second terminal is n, the first information corresponding to the second terminal may be n bits, where the i-th bit corresponds to the i-th monitoring period, i is less than or equal to n, and i and n are positive integers.

[0141] The i-th bit in the indication information can indicate whether the listening opportunity in the i-th listening cycle of the second terminal is available. For example, when the value of the i-th bit is 1, it can indicate that the listening opportunity in the i-th listening cycle is available. When the value of the i-th bit is 0, it can indicate that the listening opportunity in the i-th listening cycle is unavailable. Then n bits can indicate whether the listening opportunity in the n-th listening cycle is available.

[0142] FIG6 is a schematic diagram showing another monitoring opportunity according to an embodiment of the present disclosure.

[0143] For example, with respect to the technical problem in FIG4 , according to an embodiment of the present disclosure, the first terminal may determine that the listening timings corresponding to the three second terminals conflict. Specifically, in the first cycle, the listening timings of UE#B and UE#C conflict; in the second cycle, the listening timings of UE#A, UE#B and UE#C conflict; and in the third cycle, the listening timings of UE#B and UE#C conflict.

[0144] For example, if the number of listening cycles of UE#A is 2, and the number of listening cycles of UE#B and UE#C is 3, then after coordinating multiple listening opportunities, the first terminal can generate three first information, namely, the first information #A corresponding to UE#A, the first information #B corresponding to UE#B, and the first information #C corresponding to UE#C.

[0145] As shown in FIG6 , the first information #A occupies two bits and has a value of 10, the first information #B occupies three bits and has a value of 101, and the first information #C occupies three bits and has a value of 010.

[0146] The first terminal may send the first information #A to UE#A, the first information #B to UE#B, and the first information #C to UE#C.

[0147] Based on the first information #A, UE#A may determine to monitor the first information at a monitoring opportunity in the first monitoring cycle and not to monitor the first information at a monitoring opportunity in the second monitoring cycle. The first terminal may send the first information to UE#A at a monitoring opportunity in the first monitoring cycle of UE#A.

[0148] Based on the first information #B, UE#B may determine to monitor the first information at a monitoring opportunity in a first monitoring cycle, not to monitor the first information at a monitoring opportunity in a second monitoring cycle, and to monitor the first information at a monitoring opportunity in a third monitoring cycle. The first terminal may send the first information to UE#B at the monitoring opportunities in the first and third monitoring cycles of UE#B.

[0149] Based on the first information #C, UE#C may determine not to monitor the first information at a monitoring opportunity in a first monitoring cycle, to monitor the first information at a monitoring opportunity in a second monitoring cycle, and not to monitor the first information at a monitoring opportunity in a third monitoring cycle. The first terminal may send the first information to UE#C during the monitoring opportunity in the second monitoring cycle of UE#C.

[0150] It can be seen that, compared to monitoring the first information at two monitoring opportunities before coordination, UE#A can monitor the first information only during the monitoring opportunities in the first monitoring cycle; compared to monitoring the first information at three monitoring opportunities before coordination, UE#B can monitor the first information only during the monitoring opportunities in the first and third monitoring cycles; and compared to monitoring the first information at three monitoring opportunities before coordination, UE#C can monitor the first information only during the monitoring opportunities in the second monitoring cycle. For each second terminal, the number of monitoring opportunities after coordination is reduced compared to the monitoring opportunities before coordination, thus helping to reduce the overhead of each second terminal monitoring the first information.

[0151] In some embodiments, the starting positions of the listening periods of different second terminals may be different, and the conflicting listening opportunities between different second terminals are only the listening opportunities in some listening periods. Therefore, the first terminal may also send starting information to the second terminal. The starting information is used to indicate to the second terminal the starting position of the listening period corresponding to the adjusted listening opportunity indicated by the first information in the listening period of the second terminal.

[0152] The first information and the start information may be sent to the second terminal separately, or may be carried in one message and sent to the second terminal, which is not limited in the present disclosure.

[0153] In some embodiments, when the listening periods of multiple second terminals are of the same length and the number of listening periods corresponding to the conflicting listening opportunities is also the same, the first terminal can consider the processing capabilities of the multiple second terminals when coordinating the listening opportunities. For example, for a second terminal with relatively strong processing capabilities, the coordinated listening opportunities can be relatively more, and for a second terminal with relatively weak processing capabilities, the coordinated listening opportunities can be relatively less. Thus, the coordinated listening opportunities can match the processing capabilities of the second terminals on the basis of avoiding conflicts in the listening opportunities of multiple second terminals, which is beneficial to avoid the operation of monitoring the first information taking up too much of the processing capabilities of the second terminals.

[0154] For example, in the embodiment shown in Figure 6, the listening periods of UE#B and UE#C are the same length, and the number of listening periods corresponding to the conflicting listening opportunities is also the same. The first terminal determines that the processing capability of UE#B is relatively strong and the processing capability of UE#C is relatively weak. Therefore, the coordinated listening opportunities can be determined based on the embodiment shown in Figure 6, that is, for UE#B, there are relatively more coordinated listening opportunities, and for UE#C, there are relatively fewer coordinated listening opportunities.

[0155] In some embodiments, when coordinating monitoring timings, a first terminal may consider the latency requirements of services conducted with each second terminal. For second terminals corresponding to services requiring relatively shorter latency, the first terminal may coordinate monitoring timings relatively earlier. For second terminals corresponding to services requiring relatively longer latency, the first terminal may coordinate monitoring timings relatively later. This allows the coordinated monitoring timings to match the services of the second terminals while avoiding conflicts in the monitoring timings of multiple second terminals, thereby facilitating the satisfaction of the latency requirements of the services.

[0156] For example, in the embodiment shown in FIG6 , for UE#B and UE#C, the first terminal determines that the service with UE#B requires a relatively short delay, and the service with UE#C requires a relatively long delay. Therefore, the coordinated listening timing can be determined based on the embodiment shown in FIG6 , that is, for UE#B, the coordinated listening timing is relatively early, and for UE#C, the coordinated listening timing is relatively late.
