Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to a beam reporting method and communication device. Background Technology

[0002] Carrier aggregation (CA) is a key technology in the field of communications. CA technology achieves higher data transmission rates and more flexible spectrum allocation by aggregating multiple component carriers (CCs).

[0003] In CA-based communication scenarios, there is currently no clear event reporting mechanism when a terminal device detects multiple events being triggered. These multiple events may include, for example, events that trigger procedures for switching to alternative beams, events that trigger beam switching, or events that trigger updates to the alternative beam list. Some terminal devices may simultaneously report beam reports associated with these multiple events, leading to uplink resource contention and signaling conflicts. Other terminal devices may report beam reports associated with these multiple events in a random order, which can delay the processing of critical events and potentially affect data transmission. Summary of the Invention

[0004] This application provides a method and communication device for reporting beam reports, which can report beam reports associated with multiple events based on priority rules. This not only avoids the problems of uplink resource contention and signaling conflicts caused by simultaneous reporting, but also avoids the problem of delayed processing of key events caused by reporting in random order.

[0005] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0006] Firstly, a method for reporting beam reports is provided, applied to a network device. The method includes: detecting multiple events being triggered, and reporting beam reports associated with the multiple events according to a priority rule; wherein the priority rule is related to at least one of the following: the type of the triggered event; and the type of the cell corresponding to the triggered event.

[0007] In this application, when a terminal device detects that multiple events have been triggered, the terminal device can report beam reports associated with the multiple events to the network device according to priority rules. This can avoid uplink resource contention and signaling conflicts caused by simultaneous reporting, and can also avoid the impact of reporting in random order on the timeliness of beam switching.

[0008] In one possible implementation of the first aspect, the priority rule is as follows: the priority of the second event is higher than the priority of the first event, and the priority of the first event is higher than the priority of the third event. The first event is that the quality of the first beam is below a threshold; the second event is that the quality of at least one second beam is higher than the quality of the first beam by a threshold; and the third event is that the quality of at least one third beam is higher than the quality of the reference signal by a threshold.

[0009] The first beam is the beam currently providing service.

[0010] The second beam is the beam that is to replace the first beam in providing service. For example, the network device selects one of the at least one second beam reported by the terminal device and instructs the terminal device to use the second beam selected by the network device to replace the first beam in providing service.

[0011] The third beam is the beam to be configured into the active TCI state list. The reference signal is the reference signal corresponding to the Q-th state in the active TCI state list, where Q is a positive integer.

[0012] The first event aims to report the potential risk of degraded current beam quality, triggering a switch to an alternative beam to avoid connection interruptions caused by low current beam quality. The second event aims to quickly switch to a new, higher-quality beam to improve communication performance. The third event aims to update and maintain the alternative beam list to ensure its timeliness. Considering the need to improve communication performance, the second event has a higher priority than the first event, and the first event has a higher priority than the third event.

[0013] In one possible implementation of the first aspect, events triggered in the primary cell are processed first, with priority rules including: the second event has a higher priority than the first event, and the first event has a higher priority than the third event. For events of the same type triggered in both the primary and secondary cells, the event triggered in the primary cell has a higher priority than the event triggered in the secondary cell. For example, for a first event triggered in both the primary and secondary cells, the first event triggered in the primary cell has a higher priority than the first event triggered in the secondary cell.

[0014] In one possible implementation of the first aspect, events triggered in the secondary cell are processed first, with priority rules including: the second event has a higher priority than the first event, and the first event has a higher priority than the third event. For events of the same type that are triggered in both the primary and secondary cells, the event triggered in the secondary cell has a higher priority than the event triggered in the primary cell. For example, for a first event that is triggered in both the primary and secondary cells, the first event triggered in the secondary cell has a higher priority than the first event triggered in the primary cell.

[0015] In one possible implementation of the first aspect, considering both the transmission requirements of control signaling in the primary cell and the improvement of communication performance in the secondary cell, the priority rules include: the priority of the second event is higher than the priority of the first event, and the priority of the first event is higher than the priority of the third event. For events where either the first or third event is triggered in both the primary and secondary cells, the event triggered in the primary cell has a higher priority than the event triggered in the secondary cell. Similarly, for events where the second event is triggered in both the primary and secondary cells, the event triggered in the secondary cell has a higher priority than the event triggered in the secondary cell.

[0016] In one possible implementation of the first aspect, the priority rule is: the first event has a higher priority than the second event, and the second event has a higher priority than the third event. When a cell triggers the first event, indicating that the quality of the cell's first beam is poor, to prevent further deterioration of the first beam's quality leading to connection interruption, the first event has the highest priority when multiple events are triggered. Since the second event aims to use a better quality beam to provide service (i.e., to improve communication performance), and the third event aims to update the alternative beam list, considering the need to improve communication performance, the second event has a higher priority than the third event.

[0017] In one possible implementation of the first aspect, the transmission requirements of control signaling in the primary cell are given priority, and the priority rules include: the priority of the first event is higher than the priority of the second event, and the priority of the second event is higher than the priority of the third event. For the same type of event that is triggered in both the primary and secondary cells, the event triggered in the primary cell has a higher priority than the event triggered in the secondary cell.

[0018] In one possible implementation of the first aspect, the transmission requirements of service data in the secondary cell are given priority, and the priority rules include: the priority of the first event is higher than the priority of the second event, and the priority of the second event is higher than the priority of the third event. For the same type of event that is triggered in both the primary and secondary cells, the event triggered in the secondary cell has a higher priority than the event triggered in the primary cell.

[0019] In one possible implementation of the first aspect, considering both the transmission requirements of control signaling in the primary cell and the improvement of communication performance in the secondary cell, the priority rules include: the priority of the first event is higher than the priority of the second event, and the priority of the second event is higher than the priority of the third event. For events that are triggered in both the primary and secondary cells, the event triggered in the primary cell has a higher priority than the event triggered in the secondary cell. For events that are triggered in both the primary and secondary cells, the event triggered in the secondary cell has a higher priority than the event triggered in the secondary cell.

[0020] In one possible implementation of the first aspect, when multiple events are triggered, including multiple first events, the worse the quality of the first beam, the higher the priority of the first event. The first event aims to report the potential risk of current beam quality degradation. The worse the quality of the first beam, the greater the risk of current beam quality degradation. When multiple first events are triggered, the worse the quality of the first beam, the higher the priority for reporting beam reports associated with that first event.

[0021] In one possible implementation of the first aspect, when multiple events are triggered, including multiple second events, the better the quality of at least one second beam, the higher the priority of the second event. The second event aims to quickly switch to a new beam with better quality to improve communication performance. Therefore, when multiple second events are triggered, the better the quality of at least one second beam, the higher the priority for reporting the beam report associated with that second event.

[0022] In one possible implementation of the first aspect, when multiple events are triggered, including multiple third events, the better the quality of at least one third beam, the higher the priority of the third event. The third events are intended to update and maintain the list of candidate beams, ensuring its timeliness. Therefore, when multiple third events are triggered, the better the quality of at least one third beam, the higher the priority for reporting beam reports associated with that third event.

[0023] In one possible implementation of the first aspect, the priority rule is: events triggered in the primary cell have a higher priority than events triggered in the secondary cell. Since the primary cell carries the transmission of control signaling for all cells, events triggered in the primary cell are more critical and important. Therefore, considering the transmission requirements of control signaling, events triggered in the primary cell have a higher priority than events triggered in the secondary cell.

[0024] In one possible implementation of the first aspect, the priority rule is as follows: events triggered in the primary cell have a higher priority than events triggered in the secondary cell; for different types of events triggered in the same type of cell, the second event has a higher priority than the first event, and the first event has a higher priority than the third event. Since the primary cell carries the transmission of control signaling for all cells, events triggered in the primary cell are more critical and important. Therefore, considering the transmission requirements of control signaling, events triggered in the primary cell have a higher priority than events triggered in the secondary cell. For the same type of cell, if multiple types of events are triggered in that cell, the second event has a higher priority than the first event, and the first event has a higher priority than the third event.

[0025] In one possible implementation of the first aspect, the priority rule is as follows: events triggered in the primary cell have a higher priority than events triggered in the secondary cell; for different types of events triggered in the same type of cell, the first event has a higher priority than the second event, and the second event has a higher priority than the third event. Since the primary cell carries the transmission of control signaling for all cells, events triggered in the primary cell are more critical and important. Therefore, considering the transmission requirements of control signaling, events triggered in the primary cell have a higher priority than events triggered in the secondary cell. For either the primary or secondary cell, if the events triggered in that cell include multiple types, the first event has a higher priority than the second event, and the first event has a higher priority than the third event.

[0026] In one possible implementation of the first aspect, the priority rules include: events triggered in the primary cell have a higher priority than events triggered in the secondary cell; for events triggered in the primary cell, the second event has a higher priority than the first event, and the first event has a higher priority than the third event. For events triggered in the secondary cell, the first event has a higher priority than the second event, and the second event has a higher priority than the third event.

[0027] In one possible implementation of the first aspect, the priority rules include: the priority of the first and second events triggered in the primary cell is higher than the priority of the first and second events triggered in the secondary cell; the priority of the first and second events triggered in the secondary cell is higher than the priority of the third event triggered in the primary cell; and the priority of the third event triggered in the primary cell is higher than the priority of the third event triggered in the secondary cell; for the first and second events triggered in cells of the same type, the priority of the second event is higher than the priority of the first event.

[0028] In one possible implementation of the first aspect, the priority rules include: the priority of the first and second events triggered in the primary cell is higher than the priority of the first and second events triggered in the secondary cell; the priority of the first and second events triggered in the secondary cell is higher than the priority of the third event triggered in the primary cell; the priority of the third event triggered in the primary cell is higher than the priority of the third event triggered in the secondary cell; for the first and second events triggered in the primary cell, the priority of the second event is higher than the priority of the first event; for the first and second events triggered in the secondary cell, the priority of the first event is higher than the priority of the second event.

[0029] In one possible implementation of the first aspect, events of the same type can be triggered in multiple secondary cells. When the triggered event is a first event, the worse the quality of the first beam, the higher the priority of the first event. When the triggered event is a second event, the better the quality of at least one second beam, the higher the priority of the second event. When the triggered event is a third event, the better the quality of at least one third beam, the higher the priority of the third event.

[0030] In one possible implementation of the first aspect, the beam report associated with the first event includes: an identifier of the first event, an identifier of the first beam, and its quality. The beam report associated with the second event includes: an identifier of the second event, an identifier of at least one second beam, and its quality. The beam report associated with the third event includes: an identifier of the third event, an identifier of at least one third beam, and its quality. Where multiple second beams exist, the identifiers and qualities of the multiple second beams are sorted in descending order of quality in the corresponding beam reports. Where multiple third beams exist, the identifiers and qualities of the multiple third beams are sorted in descending order of quality in the corresponding beam reports.

[0031] Secondly, a beam report reporting method is provided, applied to a network device. The method includes: configuring an event for a terminal device so that the terminal device reports a beam report associated with the event to the network device when it detects that an event has been triggered; receiving the beam report reported by the terminal device; the beam report is reported by the terminal device according to a priority rule after detecting that multiple events have been triggered; wherein the priority rule is related to at least one of the following: the type of the triggered event; the type of the cell corresponding to the triggered event.

[0032] Thirdly, a communication system is provided, including a terminal device and a network device. The network device is configured to configure events for the terminal device, so that when the terminal device detects that an event has been triggered, it reports a beam report associated with the event to the network device; and receives the beam report reported by the terminal device. The beam report is reported by the terminal device according to a priority rule after detecting that multiple events have been triggered; wherein the priority rule is related to at least one of the following: the type of the triggered event; the type of the cell corresponding to the triggered event; and the terminal device is configured to perform the method as described in the first aspect.

[0033] Fourthly, a communication device is provided, applied to a terminal device or a network device, the device comprising: a module for performing the method of any of the above aspects and any possible implementation thereof.

[0034] Fifthly, a communication device is provided, comprising: at least one processor and an interface circuit, the interface circuit being configured to receive signals from other communication devices outside the communication device and transmit them to the processor, or to send signals from the processor to other communication devices outside the communication device, the processor implementing any of the above aspects and any possible implementations thereof via logic circuits or execution code instructions. Optionally, the communication device further comprises: a memory for storing program instructions. The processor is coupled to the memory via an interface.

[0035] In a sixth aspect, a computer-readable storage medium is provided, which stores a computer program or instructions configured to perform a method of any of the foregoing aspects and any possible implementation thereof.

[0036] In a seventh aspect, a chip system is provided, comprising: an interface circuit and a logic circuit, wherein the interface circuit is used to receive signals from other chips outside the chip and transmit them to the logic circuit, or to send signals from the logic circuit to other chips outside the chip, and the logic circuit is used to implement any of the above aspects and any possible implementation of the above aspects.

[0037] Eighthly, a computer program product is provided, comprising: a computer program or instructions that, when executed on a computer, cause the computer to perform any of the foregoing aspects and any possible implementation thereof.

[0047] Please see Figure 1 , Figure 1 This is a schematic diagram of the architecture of a communication system provided in an embodiment of this application. Figure 1 As shown, the communication system provided in this application embodiment may include a network device 10 and a terminal device 20. The network device 10 and the terminal device 20 can communicate via beamforming.

[0048] The aforementioned network devices can be devices that make decisions and process data from terminal devices. For example, network device 10 can manage beams, such as configuring beams for terminal device 20, or switching beams based on beam measurement reports reported by the terminal device.

[0049] The network device 10 in this application can be an access network device. Access network devices are sometimes also called access nodes. Access network devices have wireless transceiver capabilities for communicating with terminal devices. Access network devices include, but are not limited to, base stations, evolved NodeBs (eNodeBs), transmission reception points (TRPs) in the aforementioned communication systems, next-generation NodeBs (gNBs) in 5G mobile communication systems, access network devices or modules of access network devices in open RAN (ORAN) systems, satellites in NTN communication systems, base stations in future mobile communication systems, or access nodes in WiFi systems. Access network devices can also be modules or units capable of implementing some of the functions of a base station. Access network devices can be macro base stations, micro base stations, indoor relay nodes or donor nodes, or wireless controllers in cloud radio access network (CRAN) scenarios. Optionally, access network devices can also be servers, wearable devices, or vehicle-mounted devices, etc. For example, the access network equipment in vehicle-to-everything (V2X) technology can be a roadside unit (RSU). Multiple access network devices in a communication system can be base stations of the same type or different types. Base stations can communicate with terminal devices directly or via relay stations. Terminal devices can communicate with multiple base stations using different access technologies. The embodiments of this application do not limit the specific technology or device form used in the access network equipment. In this application, the access network equipment is referred to as a network device.

[0050] The terminal device 20 in this application embodiment can transmit data with the network device 10 via beamforming. The terminal device in this application can be a wireless terminal device capable of receiving network device scheduling and instruction information. The wireless terminal device can be a device providing voice and / or data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. For example, the terminal device can communicate with one or more core networks or the Internet via a radio access network (RAN). The terminal device can also be called a terminal, user equipment (UE), mobile station, mobile terminal, etc. The terminal device can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), Internet of Things (IoT), ultra-reliable low-latency communication (URLLC), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, smart cities, or satellite communication, etc. The terminal can be a mobile phone, tablet computer, computer with wireless transceiver capabilities, wearable device, vehicle, aircraft (such as drone, helicopter, airplane), hot air balloon, ship, robot, robotic arm, or smart home device, etc. The embodiments of this application do not limit the form of the terminal device.

[0051] Access network equipment and / or terminal equipment can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; on water; or in the air on aircraft, balloons, and satellites. This application does not limit the application scenarios of the access network equipment and terminal equipment. They can be deployed in the same or different scenarios; for example, both can be deployed on land simultaneously; or the access network equipment can be deployed on land while the terminal equipment is deployed on water, etc., and so on.

[0052] In practical applications, multiple network devices can collaborate to assist terminals in achieving wireless access, with different network devices each implementing a portion of the base station's functions. For example, network devices can be central units (CUs), distributed units (DUs), CU-control plane (CPs), CU-user plane (UPs), or radio units (RUs), etc. CUs and DUs can be set up separately or included in the same network element, such as a baseband unit (BBU). RUs can be included in radio frequency equipment or radio frequency units, such as remote radio units (RRUs), active antenna units (AAUs), or remote radio heads (RRHs).

[0053] In different systems, CU (or CU-CP and CU-UP), DU, or RU may have different names, but those skilled in the art will understand their meaning. For example, in an ORAN system, CU can also be called O-CU (Open CU), DU can also be called O-DU, CU-CP can also be called O-CU-CP, CU-UP can also be called O-CU-UP, and RU can also be called O-RU. Any of the units among CU (or CU-CP, CU-UP), DU, and RU in this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules. CU (or CU-CP and CU-UP), DU, and RU can implement different protocol layer functions.

[0054] To facilitate understanding of the embodiments of this application, the terminology used in this application will be briefly explained first. Optionally, the explanation of some terms may also refer to the explanations in the 3rd Generation Partnership Project (3GPP) standard protocol.

[0055] Carrier aggregation (CA) technology is a key technology in the field of communications. CA achieves higher data transmission rates and more flexible spectrum allocation by aggregating multiple component carriers (CCs). For example, CA aggregates two or more component carriers together to obtain greater bandwidth. These two or more component carriers include one primary component carrier (PCC) and multiple secondary component carriers (SCCs). One PCC corresponds to one primary cell (PCell), and multiple SCCs correspond to multiple secondary cells (SCells). The PCC is used to carry signaling transmissions for all cells, including the primary and secondary cells. The SCCs are used to carry service data transmissions.

[0056] It should be understood that the technical terms used in this application are for illustrative purposes only and not as limiting. For example, as technology evolves, technical terms may also change, and other technical terms that have the same technical meaning should also apply to this application.

[0057] According to standard protocols, network devices can configure multiple events for terminal devices and assign different Channel State Information-Report Configuration Identifiers (CSI-ReportConfigIDs) to different events. For example, network devices can configure multiple events for terminal devices via Radio Resource Control (RRC) signaling. For instance, RRC signaling includes cell identification and configurations related to beam measurement. The terminal device can perform specified types of beam measurements on a designated cell according to the network device's configuration and, upon detecting one or more triggered events, report beam reports corresponding to the triggered events to the network device. For example, the terminal device reports beam reports associated with these one or more events to the network device via a first physical uplink control channel and / or a second physical uplink shared channel. There is no direct correspondence between the event type and the first physical uplink control channel and / or the second physical uplink shared channel.

[0058] In CA-based communication scenarios, there is currently no clear reporting mechanism when a terminal device detects multiple events being triggered. These multiple events may include events that trigger procedures for switching to alternative beams, events that trigger beam switching, and events that trigger updates to the alternative beam list. Some terminal devices may simultaneously report beam reports associated with these multiple events, leading to uplink resource contention and signaling conflicts. Some terminal devices may report beam reports associated with these multiple events in a random order. If beam reports associated with non-critical events are reported first, and beam reports associated with critical events are reported later, the processing of critical events will be delayed, potentially affecting the timeliness of beam switching and consequently, data transmission.

[0059] Among them, multiple events include Event 1 (Event-1), Event 2 (Event-2), and Event 7 (Event-7).

[0060] Event 1 is that the quality of the current beam is below a threshold. Event 2 is that the quality of at least one new beam is above the quality of the current beam by one threshold. Event 7 is that the quality of at least one new beam is above the quality of a reference signal by one threshold. This reference signal can be, for example, the Qth reference signal in the candidate beam list. The candidate beam list can be, for example, an active transmission configuration indicator (TCI) status list, and the Qth reference signal can specifically be the reference signal corresponding to the Qth state in the active TCI status list.

[0061] For example, a terminal device detects that events 2 and 7 have been triggered in a cell, such as a primary or secondary cell. If the terminal device first reports the beam report associated with event 7 to the network device, and then reports the beam report associated with event 2, the network device will first trigger the process of updating the candidate beam list, and then trigger the beam switching process. However, event 2 aims to achieve fast switching to a high-quality new beam and optimize communication performance. The delayed reporting of the beam report associated with event 2 will cause the beam switching process triggered by event 2 to be delayed, resulting in a delay in the fast switching to a high-quality new beam.

[0062] For example, a terminal device detects events being triggered in multiple cells. For instance, the terminal device detects event 1 triggered in the primary cell and event 7 triggered in the secondary cell. If the terminal device first reports the beam report associated with event 7 triggered in the secondary cell to the network device, and then reports the beam report associated with event 1 triggered in the primary cell, the network device will first trigger the process of updating the alternative beam list. In this case, the quality of the current beam in the primary cell may continue to deteriorate, triggering the beam failure recovery mechanism. Since the primary cell handles control signaling transmission for all cells (including the secondary cells of the primary cell), the quality of the current beam in the primary cell directly affects the connection status between the terminal device and the network device. Delayed processing of event 1 triggered in the primary cell may cause the connection between the terminal device and the network device to be interrupted.

[0063] In view of this, the present application provides a method for reporting beam reports. When a terminal device detects that multiple events have been triggered, the terminal device can report beam reports associated with multiple events to the network device according to priority rules. This can avoid uplink resource contention and signaling conflicts caused by reporting beam reports associated with events at the same time, and can also avoid the impact of reporting in random order on the timeliness of beam switching.

[0064] The following detailed explanation of the solution provided in this application, in conjunction with the corresponding flowcharts, illustrates the method in detail. It is understood that the illustrative flowcharts provided in this application primarily use different devices (e.g., terminal devices, network devices) as examples of the execution entities in this interactive illustration, but this application does not limit the execution entities of the interactive illustrations. For example, the devices (e.g., terminal devices, network devices) in the illustrative flowcharts can also be chips, chip systems, or processors that support the implementation of this method on the device, or logic modules or software capable of implementing all or part of the device's functions.

[0065] As a general statement, the message or signaling interactions involved in the interaction process of this application embodiment can be standard messages or signaling or newly introduced messages or signaling. This application embodiment does not make specific limitations on this.

[0066] The embodiments of this application will be based on having Figure 1 Taking network device 10 and terminal device 20 in the communication system shown as examples, and in conjunction with the accompanying drawings and application scenarios, a beam reporting method provided in this application embodiment will be described in detail. This method is executed by the cooperation of the network device and the terminal device.

[0067] In this embodiment of the application, both the primary cell and the secondary cell of the terminal device can be referred to as the cell of the terminal device, or as the cell that provides services to the terminal device.

[0068] In this embodiment of the application, the events include a first event, a second event, and a third event.

[0069] The first event is that the quality of the first beam falls below a threshold. The first beam is the current beam, i.e., the beam currently providing service. In other words, the current beam is the beam within the cell currently providing service to the terminal device; that is, the terminal device and network device transmit data through the cell's current beam. The data can be signaling or service data. It should be understood that each cell, such as a primary cell or a secondary cell, has a corresponding current beam. The cell's current beam changes dynamically. For example, network devices cover the cell with multiple (directional) beams, and the terminal device can perform beam measurements based on the network device's configuration and report the beam measurement results to the network device. The network device dynamically adjusts the cell's current beam based on the beam measurement results reported by the terminal device. Since the cell covers its service area with multiple beams, the terminal device dynamically selects the current beam based on the quality of the multiple beams within the cell. The quality of the beam can be characterized using parameter values. Parameters can include, for example, reference signal received power (RSRP), reference signal received quality (RSRQ), and signal to interference plus noise ratio (SINR). Here, RSRP can be a physical layer (Layer 1, L1) RSRP. In some embodiments, the first event can be an Event-1 event. In some embodiments, the threshold can be a value within a range specified by a standard protocol. In some embodiments, the threshold can be pre-stored in the terminal device.

[0070] The second event is that the quality of at least one second beam is higher than the quality of the first beam by a threshold. The second beam is the beam to replace the first beam in providing service. The second beam can be described as a new beam, a candidate beam, or a neighboring beam, etc. In other words, the second event is the existence of at least one second beam with a quality higher than the quality of the first beam by a threshold. Here, "the quality of the second beam is higher than the quality of the first beam by a threshold" can be understood as: the difference between the quality of the second beam and the quality of the first beam is greater than or equal to the threshold. In some embodiments, the second event can be an Event-2 event. In some embodiments, the threshold can be a value within a range specified by a standard protocol. In some embodiments, the threshold can be pre-stored in the terminal device.

[0071] The third event is that the quality of at least one third beam is higher than the quality of the reference signal by a threshold. The third beam can be replaced by a new beam. In other words, the third event is the existence of at least one third beam whose quality is higher than the quality of the reference signal by a threshold. Here, "the quality of the third beam is higher than the quality of the reference signal by a threshold" can be understood as: the difference between the quality of the third beam and the quality of the reference signal is greater than or equal to the threshold.

[0072] The reference signal is the Qth reference signal with the best quality from the candidate beam list. The candidate beam list can be an active TCI state list. The active TCI state list includes multiple states, each corresponding to a reference signal. The multiple states are sorted from highest to lowest quality according to the reference signal. The Qth reference signal can specifically be the reference signal corresponding to the Qth state. Q is a positive integer. The third beam is specifically the beam to be configured into the active TCI state list. Configuring into the active TCI state list can be understood as activating the state corresponding to the third beam. For example, activating the m states corresponding to m third beams. Correspondingly, since the number of active states in the TCI state list is fixed, after activating the m states, the m states with the worst quality in the active TCI state list will also be activated.

[0073] It should be understood that the network device configures an active TCI status list for each cell of the terminal device. In some embodiments, the third event may be an Event-7 event. In some embodiments, the threshold may be a value within a range specified by a standard protocol. In some embodiments, the threshold may be pre-stored in the terminal device.

[0074] The threshold values ​​in the first event, the second event, and the third event can be different from each other, or the threshold values ​​in the first event, the second event, and the third event can be partially or completely the same.

[0075] In this embodiment, the network device configures the aforementioned first event, second event, and third event for the terminal device. The terminal device can periodically measure the beam quality of each cell and, based on the measurement results of the beam quality of each cell, determine whether to trigger one or more of the first event, second event, or third event. It should be understood that the network device covers the cell through multiple (directional) beams. The beam of a cell includes the current beam and other beams among the multiple beams besides the current beam. The periodic detection of the beam quality of each cell by the terminal device can be understood as: the terminal device periodically detects the quality of the current beam and the quality of other beams besides the current beam in each cell.

[0076] In this embodiment, when a terminal device detects an event being triggered, it can report a beam report associated with the event to the network device. The network device then triggers a corresponding process based on the beam report reported by the terminal device. For example, in response to a beam report associated with a first event reported by the terminal device, the network device triggers a process for switching to an alternative beam. In response to a beam report associated with a second event reported by the terminal device, the network device triggers a beam switching process. In response to a beam report associated with a third event reported by the terminal device, the network device triggers a process for updating the alternative beam list. It can be seen that the first event aims to report the potential risk of current beam quality degradation, triggering alternative beam switching to avoid connection interruptions caused by low current beam quality. The second event aims to quickly switch to a new beam with better quality to improve communication performance. The third event aims to update and maintain the alternative beam list to ensure its timeliness.

[0077] Figure 2 A beam reporting method provided in this application embodiment may include:

[0078] S1, the network device configures the first event, the second event, and the third event for the terminal device.

[0079] S2, multiple events are detected and the terminal device reports beam reports associated with the multiple events to the network device according to the priority rules.

[0080] Among them, the beam reports associated with multiple events include at least one type of beam report among beam reports associated with a first event, beam reports associated with a second event, and beam reports associated with a third event.

[0081] In some embodiments, the beam report associated with the first event may include: an identifier of the first event, an identifier of the first beam, and its quality. The quality of the first beam can be characterized by the RSRP value, which may specifically be the L1-RSRP value or the absolute value of L1-RSRP. The identifier of the first beam may specifically be the resource indicator (DL RS) of the downlink reference signal corresponding to the first beam. The identifier of the first event may, for example, be the event type of the first event.

[0082] In some embodiments, the beam report associated with the second event includes: an identifier of the second event, an identifier of at least one second beam, and its quality. The identifier of the second event may be the type of the second event.

[0083] For example, the beam report associated with the second event includes: the identifier of the second event, the identifiers of N beams, and their quality. The value of N is recorded in the configuration information of the beam report associated with the second event. N is a positive integer, for example, N∈{1,2,3,4,5,6,7,8}.

[0084] When the number of beams satisfying the triggering conditions of the second event is greater than N, the N beams in the beam report associated with the second event are the top N beams of the best quality among those satisfying the triggering conditions. In other words, when multiple beams satisfy the triggering conditions of the second event, the terminal device only reports the information of the top N beams of the best quality to the network device, discarding the information of the remaining beams to reduce signaling overhead. Specifically, the beams satisfying the triggering conditions of the second event are those whose quality is higher than the quality of the first beam by one quality threshold; these are the second beams.

[0085] When the number of beams satisfying the triggering conditions of the second event is less than N, the N beams in the beam report associated with the second event are the beams that satisfy the triggering conditions of the second event and the beams that do not satisfy the triggering conditions of the second event. The total number of beams satisfying and not satisfying the triggering conditions of the second event is N. The beams that do not satisfy the triggering conditions of the second event are beams whose quality is no higher than a threshold of the quality of the first beam. In this case, the beam report associated with the second event also carries indication information, which indicates the beams among the N beams that satisfy the triggering conditions of the second event, i.e., the second beam among the N beams. For example, the network device decides whether to enable a first preset field in configuration information such as RRC signaling based on the capabilities of the terminal device. When the first preset field is enabled, the beam report associated with the second event reported by the terminal device to the network device may also include this indication information.

[0086] If the number of beams that meet the triggering conditions of the second event is equal to N, then the N beams in the beam report associated with the second event are the N beams that meet the triggering conditions of the second event.

[0087] Taking N=7 as an example, if a cell, such as a primary or secondary cell, has 8 beams with quality exceeding a quality threshold of the first beam, the corresponding beam report includes the identifiers and quality of the top 7 beams with the best quality among these 8 beams. As another example, if a cell, such as a primary or secondary cell, has 4 beams with quality exceeding a quality threshold of the first beam, the corresponding beam report includes the identifiers and quality of these 4 beams and 3 beams with quality not exceeding a quality threshold of the first beam.

[0088] In some embodiments, the identifier and quality of at least one second beam are sorted in descending order of quality in the beam report. For example, the beam report may include information on N sets of beams, each set including the identifier and quality of a beam. These N sets of beam information are arranged sequentially in the beam report in descending order of beam quality. The N beams can be n second beams and Nn beams whose quality is no higher than a threshold of the quality of the first beam, where n is greater than or equal to 1 and less than or equal to N.

[0089] Optionally, the beam report associated with the second event may also include the identifier and quality of the first beam. For example, if the second preset field in the configuration information sent by the network device, such as RRC signaling, is enabled, the beam report associated with the second event reported by the terminal device to the network device may also include the identifier and quality of the current beam, i.e., the first beam.

[0090] In some embodiments, the beam report associated with the third event includes: an identifier of the third event, an identifier of at least one third beam, and its quality. The identifier of the third event may be the type of the third event.

[0091] For example, the beam report associated with a third event includes: the identifier of the third event, the identifiers of M beams, and their quality. The value of M is recorded in the configuration information of the beam report associated with the third event. M is a positive integer. For example, M∈{1,2,3,4,5,6,7,8}.

[0092] When the number of beams satisfying the triggering condition of the third event is greater than M, the M beams in the beam report associated with the third event are the top M beams of the best quality among those satisfying the triggering condition. In other words, when multiple beams satisfy the triggering condition of the third event, the terminal device only reports the information of the top M beams of the best quality to the network device, discarding the information of the remaining beams to reduce signaling overhead. The beam satisfying the triggering condition of the third event is the beam whose quality is higher than a threshold of the reference signal quality, i.e., the third beam.

[0093] When the number of beams satisfying the triggering conditions of the third event is less than M, the M beams in the beam report associated with the third event consist of beams that satisfy the triggering conditions and beams that do not satisfy the triggering conditions of the third event, where the total number of beams satisfying and not satisfying the triggering conditions of the third event is M. Beams that do not satisfy the triggering conditions of the third event are beams whose quality is no higher than a threshold of the reference signal quality. In this case, the beam report associated with the third event also carries indication information, which indicates the beams among the M beams that satisfy the triggering conditions of the third event, i.e., the third beam among the M beams. For example, the network device decides whether to enable the third preset field in configuration information such as RRC signaling based on the capabilities of the terminal device. When the third preset field is enabled, the beam report associated with the third event reported by the terminal device to the network device may also include this indication information.

[0094] If the number of beams that meet the triggering conditions of the third event is equal to M, then the M beams in the beam report associated with the third event are the M beams that meet the triggering conditions of the third event.

[0095] Taking M=6 as an example, if a cell, such as a primary or secondary cell, has 9 beams with quality exceeding a threshold of the reference signal, the corresponding beam report includes the identifiers and quality of the top 6 beams with the best quality among these 9 beams. As another example, if a cell, such as a primary or secondary cell, has 3 beams with quality exceeding a threshold of the reference signal, the corresponding beam report includes the identifiers and quality of these 3 beams and 3 beams with quality not exceeding a threshold of the reference signal.

[0096] In some embodiments, the identifiers and qualities of the M beams are sorted in descending order of quality in the beam report. For example, the beam report may include information on M groups of beams, each group including the identifier of a beam and its quality. These M groups of beam information are arranged sequentially in the beam report in descending order of beam quality. The M beams may be m third beams and Mm beams whose quality is no higher than a threshold of the reference signal quality, where m is greater than or equal to 1 and less than or equal to M.

[0097] Optionally, the beam report associated with the third event may also include the identifier and quality of the Qth reference signal in the active TCI status list. For example, if the fourth preset field of configuration information such as RRC signaling sent by the network device is enabled, the beam report associated with the third event reported by the terminal device to the network device may further include the identifier and quality of the Qth reference signal in the active TCI status list.

[0098] The quality of the N or M beams mentioned above can be characterized by the RSRP value, which can specifically be the L1-RSRP value or the absolute value of L1-RSRP. In some embodiments, the quality of the best-quality beam among the N or M beams can be characterized by the RSRP value, while the quality of the remaining N-1 or M-1 beams can be characterized by the differential L1-RSRP value. The differential L1-RSRP is the difference between the L1-RSRP value of the beam and the L1-RSRP value of the best-quality beam. The identification of the N or M beams can specifically be the resource indicator (DL RS) of the downlink reference signal corresponding to the beam. The resource indicator of the downlink reference signal corresponds one-to-one with the beam and is used by the terminal equipment to measure the corresponding beam.

[0099] In some embodiments, if a terminal device detects that an event has been triggered in only one cell, the terminal device may report a beam report associated with this single event to the network device. This scenario can be referred to as a single-cell, single-event scenario. The single event can be any type of event among the first event, the second event, or the third event.

[0100] In other embodiments, if a terminal device detects that at least two types of events, namely a first event, a second event, or a third event, have been triggered in a single cell, the terminal device can report beam reports associated with these at least two types of events to the network device based on a priority rule. The priority rule is that the second event has a higher priority than the first event, and the first event has a higher priority than the third event. For example, if a terminal device detects that a first event, a second event, and a third event have been triggered in a single cell, the terminal device, based on the priority rule, first reports a beam report associated with the second event to the network device, then reports a beam report associated with the first event, and finally reports a beam report associated with the third event. This scenario can be referred to as a single-cell multi-event scenario.

[0101] In other embodiments, the terminal device detects an event triggered in multiple cells, and can report a beam report associated with the event to the network device according to priority rules. The type of the event triggered in multiple cells can be the same or different. This scenario can be referred to as a multi-cell single-event scenario.

[0102] In other embodiments, if a terminal device detects that at least two types of events, namely a first event, a second event, or a third event, have been triggered in multiple cells, the terminal device can report a beam report associated with the event to the network device according to a priority rule. This scenario can be referred to as a multi-cell, multi-event scenario.

[0103] The following will describe specific embodiments in detail, which will not be repeated here.

[0104] Priority rules can be pre-stored in the terminal device. The priority rules are related to the type of the triggered event and / or the type of the cell corresponding to the triggered event. The types of triggered events include first events, second events, and third events. The cell types corresponding to the triggered events include primary cells and secondary cells. The cell corresponding to the triggered event can be understood as the cell that triggered the event, or the event being triggered in that cell. For example, "the cell corresponding to the triggered event is a primary cell" can be understood as the cell that triggered the event being a primary cell, or in other words, the event being triggered in a primary cell.

[0105] The following description will be based on specific examples.

[0106] Example 1:

[0107] Priority rules are related to the type of event being triggered.

[0108] The priority rules are shown in Table 1. The priority of the second event is higher than that of the first event, and the priority of the first event is higher than that of the third event.

[0109] Table 1

[0110]

[0111] If multiple events are detected, the terminal device can report beam reports associated with the multiple events to the network device according to the priority rules shown in Table 1.

[0112] For example, in the case of multiple triggered events including a first event, a second event, and a third event, the terminal device reports the beam report associated with the second event to the network device first, then reports the beam report associated with the first event to the network device, and finally reports the beam report associated with the third event to the network device, according to the priority rule.

[0113] As another example, when multiple events are triggered, including at least two types of events such as a first event, a second event, and a third event, the terminal device reports the beam reports associated with the multiple events sequentially according to the priority rules shown in Table 1. For instance, when multiple events are triggered, including a first event and a second event, the terminal device reports the beam report associated with the second event to the network device first, and then reports the beam report associated with the first event to the network device, according to the priority rules.

[0114] In some embodiments, when there are multiple events of the same type, the terminal device may report multiple beam reports associated with this type of event in a random order. For example, when the triggered multiple events include multiple second events, the terminal device may report multiple beam reports associated with the multiple second events in a random order.

[0115] It should be understood that a cell can trigger multiple types of events simultaneously. For example, a cell can trigger at least one type of event, such as a first event, a second event, or a third event. For the same type of event, a cell can only trigger it once at a time.

[0116] For example, consider a primary cell, secondary cell A, secondary cell B, and secondary cell C that provide services to a terminal device. The terminal device detects that a first event and a second event are triggered in the primary cell, a second event and a third event are triggered in secondary cell A, a first event and a third event are triggered in secondary cell B, and a first event, a second event, and a third event are triggered in secondary cell C.

[0117] The terminal device can prioritize reporting multiple beam reports associated with multiple second events in a random order. For example, the terminal device can report beam reports associated with a second event triggered in the primary cell, a second event triggered in secondary cell A, and a second event triggered in secondary cell C in a random order. Next, the terminal device can report multiple beam reports associated with multiple first events in a random order. For example, the terminal device can report beam reports associated with a first event triggered in the primary cell, a first event triggered in secondary cell B, and a first event triggered in secondary cell C in a random order. Finally, the terminal device can report multiple beam reports associated with multiple third events in a random order. For example, the terminal device can report beam reports associated with a third event triggered in secondary cell A, a third event triggered in secondary cell B, and a third event triggered in secondary cell C in a random order.

[0118] In other embodiments, when there are multiple events of the same type, the terminal device can report multiple beam reports associated with this type of event in a preset order.

[0119] For example, when multiple triggered events include multiple first events, the terminal device can report multiple beam reports associated with the multiple first events according to the quality of the first beam. For instance, the worse the quality of the first beam, the higher the priority of the corresponding first event, meaning that beam reports associated with that event are reported first. In other words, when multiple first events are triggered, the terminal device reports multiple beam reports associated with the multiple first events sequentially in ascending order of first beam quality from low to high.

[0120] For example, when multiple triggered events include multiple second events, the terminal device reports multiple beam reports associated with the multiple second events according to the quality of the second beams. For instance, the better the quality of the n second beams, the higher the priority of the second event, meaning that beam reports associated with that event are reported first. The quality of the n second beams can be represented by the average quality of the n second beams. The higher the average quality of the n second beams, the better the quality of the n second beams. In other words, when multiple second events are triggered, the terminal device reports the beam reports associated with the second events triggered in the corresponding cells in descending order of the average quality of the n second beams in the cell.

[0121] For example, when multiple triggered events include multiple third events, the terminal device reports multiple beam reports associated with the multiple third events according to the quality of m third beams in the cell. For instance, the better the quality of the m third beams, the higher the priority of the third event, meaning that beam reports associated with that event are reported first. The quality of the m third beams can be represented by the average quality of the m third beams. The higher the average quality of the m third beams, the better their quality. In other words, when multiple third events are triggered, the terminal device reports the beam reports associated with the third events triggered in the corresponding cells sequentially, arranged in descending order of the average quality of the m third beams in the cell.

[0122] For example, when multiple first, second, and third events are triggered, the priority rules are as shown in Table 2. Specifically, multiple second events arranged in descending order of the average quality of n second beams have a higher priority than multiple first events arranged in ascending order of the quality of the first beams; and multiple first events arranged in ascending order of the quality of the first beams have a higher priority than multiple third events arranged in descending order of the average quality of m third beams.

[0123] Table 2

[0124]

[0125] Continuing with the example from earlier, the terminal device can prioritize reporting beam reports associated with the second event based on priority rules. Since the second event was triggered in multiple cells, the terminal device reports the beam reports associated with the second event triggered in the corresponding cell in descending order of the average quality of the n second beams in that cell. Taking RSRP as an example, the average RSRP of the n second beams in the primary cell is -60 dBm, the average RSRP of the n second beams in secondary cell A is -50 dBm, and the average RSRP of the n second beams in secondary cell C is -75 dBm. Therefore, the terminal device can first report the beam report associated with the second event triggered in secondary cell A, then report the beam report associated with the second event triggered in the primary cell, and finally report the beam report associated with the second event triggered in secondary cell C.

[0126] Next, the terminal device can report beam reports associated with the first event based on priority rules. Since the first event was triggered in multiple cells, the terminal device can report the corresponding beam reports sequentially in ascending order of first beam quality, from lowest to highest. Taking RSRP as an example, if the RSRP of the first beam in the primary cell is -90 dBm, the RSRP of the first beam in secondary cell B is -95 dBm, and the RSRP of the first beam in secondary cell C is -100 dBm, then the terminal device can first report the beam report associated with the first event triggered in secondary cell C, then report the beam report associated with the first event triggered in secondary cell B, and finally report the beam report associated with the first event triggered in the primary cell.

[0127] Finally, the terminal device can report beam reports associated with the third event based on priority rules. Since the third event was triggered in multiple cells, the terminal device can report the beam reports associated with the third event triggered in the corresponding cell in descending order of the average quality of the m third beams in the cell. Taking RSRP as an example, the average RSRP of the m third beams in secondary cell A is -50 dBm, the average RSRP of the m third beams in secondary cell B is -44 dBm, and the average RSRP of the m third beams in secondary cell C is -30 dBm. Therefore, the terminal device can first report the beam report associated with the third event triggered in secondary cell C, then report the beam report associated with the third event triggered in secondary cell B, and finally report the beam report associated with the third event triggered in secondary cell A.

[0128] This embodiment considers improving communication performance and sets corresponding priorities. The greater the impact of an event type on improving communication performance, the higher its priority. Specifically, the events with the greatest impact on improving communication performance, from largest to smallest, are: the second event, the first event, and the third event. Correspondingly, their priorities, from highest to lowest, are: the second event, the first event, and the third event.

[0129] Optionally, this solution is also applicable to scenarios based on coordinated multi-point (CoMP) technology. CoMP technology optimizes the signal quality and data transmission efficiency of terminal devices by coordinating the transmission and reception of data by multiple transmit / receive points (TRPs). In some embodiments, multiple TRPs may be located within the coverage area of ​​the same base station or the same logical cell. For example, multiple TRPs may be located within the coverage area managed by the same base station (gNB) or logical cell. They typically share the same physical cell identifier, or are configured as different entities under the same controlling gNB. In other embodiments, multiple TRPs may be located within the coverage areas of different base stations or different logical cells.

[0130] In CoMP scenarios, such as Figure 3 As shown, the UE can communicate with both TRP1 and TRP2 simultaneously. There is no primary or secondary distinction among the multiple TRPs. The terminal device can perform beam measurements individually on each of the multiple TRPs to determine whether a first event, second event, or third event has been triggered. After detecting that an event has been triggered, the terminal device can report beam reports associated with multiple events according to the priority rules described above. For example, if multiple types of events are triggered in one TRP, beam reports associated with the second event are reported first, followed by beam reports associated with the first event, and finally beam reports associated with the third event. Alternatively, if multiple types of events are triggered in multiple TRPs, the corresponding beam reports are reported according to the priority rules shown in Embodiment 1. For example, the priority of the second event is higher than the priority of the first event, and the priority of the first event is higher than the priority of the third event. When multiple triggered events include multiple first events, the worse the quality of the first beam, the higher the priority of the corresponding first event. When multiple triggered events include multiple second events, the better the quality of the n second beams, the higher the priority of the second event. In the case of multiple triggered events, including multiple third events, the better the quality of the m third beams, the higher the priority of the third events.

[0131] Example 2:

[0132] Priority rules are related to the type of the triggered event and the type of cell corresponding to the triggered event.

[0133] The priority rule is as follows: the second event has a higher priority than the first event, and the first event has a higher priority than the third event. For the same type of event that is triggered in both the primary and secondary cells, the event triggered in the primary cell has a higher priority than the event triggered in the secondary cell.

[0134] Table 3

[0135]

[0136] Specifically, as shown in Table 3, the priority of a second event triggered in the primary cell is higher than that of a second event triggered in the secondary cell; the priority of a second event triggered in the secondary cell is higher than that of a first event triggered in the primary cell; the priority of a first event triggered in the primary cell is higher than that of a first event triggered in the secondary cell; the priority of a first event triggered in the secondary cell is higher than that of a third event triggered in the primary cell; and the priority of a third event triggered in the primary cell is higher than that of a third event triggered in the secondary cell.

[0137] In some embodiments, when the same type of event is triggered in multiple secondary cells, the terminal device reports multiple beam reports associated with the multiple events of the same type to the network device in a random order. For example, when a second event is triggered in multiple secondary cells, the terminal device may report multiple beam reports associated with the second event triggered in multiple secondary cells in a random order.

[0138] For example, consider a primary cell, secondary cell A, secondary cell B, and secondary cell C that provide services to a terminal device. The terminal device detects that a first event and a second event are triggered in the primary cell, a second event and a third event are triggered in secondary cell A, a first event and a third event are triggered in secondary cell B, and a first event, a second event, and a third event are triggered in secondary cell C.

[0139] Based on priority rules, the terminal device prioritizes reporting beam reports associated with the second event. Since the second event was triggered in both the primary cell and multiple secondary cells, the terminal device first reports the beam report associated with the second event triggered in the primary cell, and then reports the beam reports associated with the second events triggered in secondary cells A and C in a random order. Next, the terminal device reports beam reports associated with the first event based on priority rules. Since the first event was triggered in both the primary cell and multiple secondary cells, the terminal device may first report the beam report associated with the first event triggered in the primary cell, and then report the beam reports associated with the first event triggered in secondary cells B and C in a random order. Finally, the terminal device reports beam reports associated with the third event according to priority rules. Since the third event was triggered in multiple secondary cells, the terminal device may report the beam reports associated with the third event triggered in secondary cells A, B, and C in a random order.

[0140] In some embodiments, when the same type of event is triggered in multiple secondary cells, the terminal device reports multiple beam reports associated with the same type of event to the network device in a preset order.

[0141] For example, when a first event is triggered in multiple secondary cells, the worse the quality of the first beam, the higher the priority of the first event, meaning that beam reports associated with that event are reported first. In other words, when a first event is triggered in multiple secondary cells, the terminal device reports multiple beam reports associated with the first event triggered in multiple secondary cells in ascending order of first beam quality from low to high.

[0142] For example, when a second event is triggered in multiple secondary cells, the better the quality of the n second beams, the higher the priority of the second event, meaning that beam reports associated with that event are reported first. In other words, when a second event is triggered in multiple secondary cells, the terminal device reports the beam reports associated with the second event triggered in the corresponding secondary cell in descending order of the average quality of the n second beams in the secondary cells.

[0143] For example, when a third event is triggered in multiple secondary cells, the better the quality of the m third beams, the higher the priority of the third event, meaning that beam reports associated with that event are reported first. In other words, when a third event is triggered in multiple secondary cells, the terminal device reports the beam reports associated with the third event triggered in the corresponding secondary cell in descending order of the average quality of the m third beams in the secondary cells.

[0144] For example, when multiple secondary cells trigger the first, second, and third events, the priority rules are as shown in Table 4. Specifically, the priority of a second event triggered in the primary cell is higher than the priority of multiple second events triggered in secondary cells, arranged in descending order of the average quality of n second beams; the priority of multiple second events triggered in secondary cells, arranged in descending order of the average quality of n second beams, is higher than the priority of the first event triggered in the primary cell; the priority of a first event triggered in the primary cell is higher than the priority of multiple first events triggered in secondary cells, arranged in ascending order of the quality of the first beam; the priority of multiple first events triggered in secondary cells, arranged in ascending order of the quality of the first beam, is higher than the priority of the third event triggered in the primary cell; and the priority of a third event triggered in the primary cell is higher than the priority of multiple third events triggered in secondary cells, arranged in descending order of the average quality of m third beams.

[0145] Table 4

[0146]

[0147] Continuing with the example from the previous text, when reporting multiple beam reports associated with multiple second events triggered in secondary cells, since the average RSRP of n second beams in secondary cell A is -50 dBm and the average RSRP of n second beams in secondary cell C is -75 dBm, the terminal device can first report the beam report associated with the second event triggered in secondary cell A, and then report the beam report associated with the second event triggered in secondary cell C.

[0148] When reporting beam reports associated with multiple first events triggered in secondary cells, since the RSRP of the first beam in secondary cell B is -95 dBm and the RSRP of the first beam in secondary cell C is -100 dBm, the terminal device can prioritize reporting the beam report associated with the first event triggered in secondary cell C, and then report the beam report associated with the first event triggered in secondary cell B.

[0149] When reporting beam reports associated with multiple third events triggered in secondary cells, since the average RSRP of m third beams in secondary cell A is -50 dBm, the average RSRP of m third beams in secondary cell B is -44 dBm, and the average RSRP of m third beams in secondary cell C is -30 dBm, the terminal device can first report the beam report associated with the third event triggered in secondary cell C, then report the beam report associated with the third event triggered in secondary cell B, and finally report the beam report associated with the third event triggered in secondary cell A.

[0150] This embodiment takes into account the need to improve communication performance; the greater the impact of an event type on improving communication performance, the higher its corresponding priority. Simultaneously, considering the transmission requirements of control signaling, for the same type of event triggered in both the primary and secondary cells, the event triggered in the primary cell has a higher priority than the event triggered in the secondary cell.

[0151] In some embodiments, since secondary cells carry the transmission of service data, considering the transmission requirements of service data, events triggered in secondary cells are more critical for the same type of event. Therefore, for the same type of event, events triggered in secondary cells have a higher priority than events triggered in primary cells.

[0152] For example, the priority rule could be: the second event has a higher priority than the first event, and the first event has a higher priority than the third event. For events of the same type that are triggered in both the primary and secondary cells, the event triggered in the secondary cell has a higher priority than the event triggered in the primary cell. This same type of event can be the first event, the second event, or the third event. For instance, taking the first event as an example, for a first event triggered in both the primary and secondary cells, the first event triggered in the secondary cell has a higher priority than the first event triggered in the primary cell.

[0153] For example, since the secondary cell carries the transmission of service data, for a second event triggered in both the primary and secondary cells, prioritizing the second event triggered in the secondary cell directly improves data transmission performance and user experience. Therefore, the priority rule could be: the second event has a higher priority than the first event, and the first event has a higher priority than the third event. Specifically, for a first event triggered in both the primary and secondary cells, the event triggered in the primary cell has a higher priority than the event triggered in the secondary cell. Similarly, for a second event triggered in both the primary and secondary cells, the event triggered in the secondary cell has a higher priority than the event triggered in the primary cell. Finally, for a third event triggered in both the primary and secondary cells, the event triggered in the primary cell has a higher priority than the event triggered in the secondary cell.

[0154] Example 3:

[0155] If a primary or secondary cell triggers the first event, it indicates a degradation in the quality of the cell's first beam. To prevent further degradation of the first beam's quality and subsequent connection interruption, the first event has the highest priority when multiple events are triggered. This ensures the rapid activation of the alternative beam process, preventing further degradation of the first beam's quality in the cell that triggered the first event. Therefore, the priority rules are as shown in Table 5: the first event has a higher priority than the second event, and the second event has a higher priority than the third event.

[0156] Table 5

[0157]

[0158] This embodiment only considers event types and does not distinguish between cell types. The first, second, and third events can all be triggered in the primary and / or secondary cells.

[0159] Optionally, if there are multiple events of the same type, the terminal device can report multiple beam reports associated with this type of event in a preset order. Refer to the description in Embodiment 1; it will not be repeated here.

[0160] In some embodiments, considering the transmission requirements of control signaling, events triggered in the primary cell have a higher priority than events triggered in the secondary cell. Therefore, the priority rule could be: the first event has a higher priority than the second event, and the second event has a higher priority than the third event. For events of the same type that are triggered in both the primary and secondary cells, the event triggered in the primary cell has a higher priority than the event triggered in the secondary cell. This same type of event can be the first event, the second event, or the third event. For example, taking the first event as an example, for a first event triggered in both the primary and secondary cells, the first event triggered in the primary cell has a higher priority than the first event triggered in the secondary cell.

[0161] In other embodiments, considering the transmission requirements of service data, events triggered in the secondary cell have a higher priority than events triggered in the primary cell. Therefore, the priority rule could be: the first event has a higher priority than the second event, and the second event has a higher priority than the third event. For events of the same type that are triggered in both the primary and secondary cells, the event triggered in the secondary cell has a higher priority than the event triggered in the primary cell. This same type of event can be the first event, the second event, or the third event. For example, taking the first event as an example, for a first event triggered in both the primary and secondary cells, the first event triggered in the secondary cell has a higher priority than the first event triggered in the primary cell.

[0162] In other embodiments, considering both the transmission requirements of control signaling and service data, the priority of a second event triggered in the secondary cell is higher than that of a second event triggered in the primary cell. Since the secondary cell carries the transmission of service data, this maximizes service transmission performance. For both the first and third events, the event triggered in the primary cell has a higher priority than the event triggered in the secondary cell. Therefore, the priority rule can be: the first event has a higher priority than the second event, and the second event has a higher priority than the third event. For either the first or third event triggered in both the primary and secondary cells, the event triggered in the primary cell has a higher priority than the event triggered in the secondary cell. For the second event triggered in both the primary and secondary cells, the event triggered in the secondary cell has a higher priority than the event triggered in the primary cell. This embodiment comprehensively considers both the transmission requirements of control signaling and service data. For the first event ensuring connection stability, events in the primary cell are processed first; for the second event improving data transmission performance, events in the secondary cell are processed first, achieving a balance between connection transmission requirements and transmission performance.

[0163] Optionally, when the same type of event is triggered in multiple secondary cells, the terminal device reports multiple beam reports associated with the same type of event to the network device in a preset order. Refer to the description in Embodiment 2; it will not be repeated here.

[0164] Example 4:

[0165] The priority rules are related to the type of cell corresponding to the triggered event.

[0166] The priority rule is: events triggered in the primary cell have a higher priority than events triggered in the secondary cell, as shown in Table 6.

[0167] Table 6

[0168]

[0169] An event triggered in the primary cell can be at least one of the following: a first event triggered in the primary cell, a second event triggered in the primary cell, and a third event triggered in the primary cell. Similarly, an event triggered in the secondary cell can be at least one of the following: a first event triggered in the secondary cell, a second event triggered in the secondary cell, and a third event triggered in the secondary cell. In other words, events of any type triggered in the primary cell are reported first, followed by events of any type triggered in the secondary cell.

[0170] For example, consider a primary cell, secondary cell A, secondary cell B, and secondary cell C that provide services to a terminal device. The terminal device detects that a first event and a second event are triggered in the primary cell, a second event and a third event are triggered in secondary cell A, a first event and a third event are triggered in secondary cell B, and a first event, a second event, and a third event are triggered in secondary cell C.

[0171] The terminal device may prioritize reporting beam reports associated with a first event triggered in the primary cell, and then beam reports associated with a second event triggered in the primary cell. The terminal device may report these two beam reports in a random order. Next, the terminal device may report beam reports associated with an event triggered in the secondary cell in a random order.

[0172] In this embodiment, since the primary cell carries the transmission of control signaling for all cells, considering the transmission requirements of control signaling, events triggered in the primary cell have a higher priority than events triggered in the secondary cell.

[0173] Example 5:

[0174] Priority rules are related to the type of the triggered event and the type of cell corresponding to the triggered event.

[0175] The priority rules are as follows: events triggered in the primary cell have a higher priority than events triggered in the secondary cell; for different types of events triggered in the same type of cell, the second event has a higher priority than the first event, and the first event has a higher priority than the third event.

[0176] Specifically, as shown in Table 7, the priority of a second event triggered in the primary cell is higher than the priority of a first event triggered in the primary cell; the priority of a first event triggered in the primary cell is higher than the priority of a third event triggered in the primary cell; the priority of a third event triggered in the primary cell is higher than the priority of a second event triggered in the secondary cell; the priority of a second event triggered in the secondary cell is higher than the priority of a first event triggered in the secondary cell; and the priority of a first event triggered in the secondary cell is higher than the priority of a third event triggered in the secondary cell.

[0177] Table 7

[0178]

[0179] In some embodiments, when the same type of event is triggered in multiple secondary cells, the terminal device reports multiple beam reports associated with the same type of event to the network device in a random order. Please refer to the description in Embodiment 2, which will not be repeated here.

[0180] In some embodiments, when the same type of event is triggered in multiple secondary cells, the terminal device reports multiple beam reports associated with the same type of event to the network device in a preset order. The preset order may be: the worse the quality of the first beam, the higher the priority of the corresponding first event; the better the quality of the n second beams, the higher the priority of the second event; the better the quality of the m third beams, the higher the priority of the third event. A higher event priority indicates a higher priority for reporting the beam report associated with that event. Please refer to the description in Embodiment 2 for details, which will not be repeated here.

[0181] For example, when a first event, second event, or third event is triggered in multiple secondary cells, the priority rules are as shown in Table 8. Specifically, the priority of a second event triggered in the primary cell is higher than the priority of a first event triggered in the primary cell; the priority of a first event triggered in the primary cell is higher than the priority of a third event triggered in the primary cell; the priority of a third event triggered in the primary cell is higher than the priority of multiple second events triggered in secondary cells, arranged in descending order of the average quality of n second beams; the priority of multiple second events triggered in secondary cells, arranged in descending order of the average quality of n second beams, is higher than the priority of multiple first events triggered in secondary cells, arranged in ascending order of the quality of the first beam; the priority of multiple first events triggered in secondary cells, arranged in ascending order of the quality of the first beam, is higher than the priority of multiple third events triggered in secondary cells, arranged in descending order of the average quality of m third beams. It should be understood that the larger the average quality of the n second beams, the better the quality of the n second beams. The higher the average quality of the m third beams, the better the quality of the m third beams.

[0182] Table 8

[0183]

[0184] For example, if the cells providing services to the terminal device include a primary cell, secondary cell A, secondary cell B, and secondary cell C, the terminal device detects that a first event and a second event are triggered in the primary cell, a second event and a third event are triggered in secondary cell A, a first event and a third event are triggered in secondary cell B, and a first event, a second event, and a third event are triggered in secondary cell C.

[0185] The terminal device can prioritize reporting beam reports associated with events triggered in the primary cell based on priority rules. Since both the first and second events were triggered in the primary cell, the terminal device can prioritize reporting the beam report associated with the second event triggered in the primary cell, and then report the beam report associated with the first event triggered in the primary cell.

[0186] Next, the terminal device reports beam reports associated with the events triggered in the secondary cell based on priority rules. Since the first event, the second event, and the third event were triggered in the secondary cell, the terminal device can prioritize reporting the beam report associated with the second event triggered in the secondary cell, then report the beam report associated with the first event triggered in the secondary cell, and finally report the beam report associated with the third event triggered in the secondary cell.

[0187] For example, the terminal device can sequentially report beam reports associated with the second event triggered in secondary cell A, the second event triggered in secondary cell C, the first event triggered in secondary cell C, the first event triggered in secondary cell B, the third event triggered in secondary cell C, the third event triggered in secondary cell B, and the third event triggered in secondary cell A, according to priority rules and a preset order.

[0188] In this embodiment, considering the transmission requirements of control signaling, events triggered in the primary cell have a higher priority than events triggered in the secondary cell. Simultaneously, considering the need to improve the communication performance of both the primary and secondary cells, when multiple types of events are triggered in the same type of cell, the priorities from highest to lowest are: second event, first event, and third event.

[0189] In some embodiments, considering the transmission requirements of service data, a first event is triggered in the secondary cell, indicating that the quality of the current beam in the secondary cell has deteriorated. To avoid further deterioration of the current beam quality and subsequent connection interruption, the first event has the highest priority among events triggered in the secondary cell. Therefore, the priority rule is: the priority of an event triggered in the primary cell is higher than the priority of an event triggered in the secondary cell. For the first, second, and third events triggered in the primary cell, the second event has a higher priority than the first event, and the first event has a higher priority than the third event. For the first, second, and third events triggered in the secondary cell, the first event has a higher priority than the second event, and the second event has a higher priority than the third event. In this embodiment, considering the transmission requirements of control signaling, the priority of events triggered in the primary cell is higher than the priority of events triggered in the secondary cell. Simultaneously, considering the need to improve the communication performance of the primary cell, when multiple types of events are triggered in the primary cell, the priorities from highest to lowest are: second event, first event, and third event. Furthermore, considering the transmission requirements of business data, when multiple types of events are triggered in the secondary cell, the priority from high to low is as follows: first event, second event, and third event.

[0190] Example 6:

[0191] Priority rules are related to the type of the triggered event and the type of cell corresponding to the triggered event.

[0192] The priority rules are as follows: the first and second events triggered in the primary cell have higher priority than the first and second events triggered in the secondary cell; the first and second events triggered in the secondary cell have higher priority than the third event triggered in the primary cell; and the third event triggered in the primary cell has higher priority than the third event triggered in the secondary cell. For the first and second events triggered in cells of the same type, the second event has higher priority than the first event.

[0193] Table 9

[0194]

[0195] For example, as shown in Table 9, the priority of a second event triggered in the primary cell is higher than the priority of a first event triggered in the primary cell; the priority of a first event triggered in the primary cell is higher than the priority of a second event triggered in the secondary cell; the priority of a second event triggered in the secondary cell is higher than the priority of a first event triggered in the secondary cell; the priority of a first event triggered in the secondary cell is higher than the priority of a third event triggered in the primary cell; and the priority of a third event triggered in the primary cell is higher than the priority of a third event triggered in the secondary cell.

[0196] In some embodiments, when the same type of event is triggered in multiple secondary cells, the terminal device reports multiple beam reports associated with the same type of event to the network device in a random order. Please refer to the description in Embodiment 2, which will not be repeated here.

[0197] In some embodiments, when the same type of event is triggered in multiple secondary cells, the terminal device reports multiple beam reports associated with the same type of event to the network device in a preset order. The preset order may be: the worse the quality of the first beam, the higher the priority of the corresponding first event; the better the quality of the n second beams, the higher the priority of the second event; the better the quality of the m third beams, the higher the priority of the third event. A higher event priority indicates a higher priority for reporting the beam report associated with that event. Please refer to the description in Embodiment 2 for details, which will not be repeated here.

[0198] For example, when multiple secondary cells trigger the first, second, and third events, the priority rules are shown in Table 10. Specifically, the priority of a second event triggered in the primary cell is higher than the priority of a first event triggered in the primary cell; the priority of a first event triggered in the primary cell is higher than the priority of multiple second events triggered in secondary cells, arranged in descending order of the average quality of the n second beams; the priority of multiple second events triggered in secondary cells, arranged in descending order of the average quality of the n second beams, is higher than the priority of multiple first events triggered in secondary cells, arranged in ascending order of the quality of the first beam; the priority of multiple first events triggered in secondary cells, arranged in ascending order of the quality of the first beam, is higher than the priority of a third event triggered in the primary cell; and the priority of a third event triggered in the primary cell is higher than the priority of multiple third events triggered in secondary cells, arranged in descending order of the average quality of the m third beams. It should be understood that the larger the average quality of the n second beams, the better the quality of the n second beams. The higher the average quality of the m third beams, the better the quality of the m third beams.

[0199] Table 10

[0200]

[0201] For example, if the cells providing services to the terminal device include a primary cell, secondary cell A, secondary cell B, and secondary cell C, the terminal device detects that a first event and a second event are triggered in the primary cell, a second event and a third event are triggered in secondary cell A, a first event and a third event are triggered in secondary cell B, and a first event, a second event, and a third event are triggered in secondary cell C.

[0202] According to priority rules, the terminal device prioritizes reporting beam reports associated with a first event triggered in the primary cell and beam reports associated with a second event triggered in the primary cell. When reporting these two beam reports, since the second event has a higher priority than the first event in the same type of cell, the terminal device may prioritize reporting the beam report associated with the second event triggered in the primary cell, and then report the beam report associated with the first event triggered in the primary cell.

[0203] Next, the terminal device reports the beam report associated with the first event triggered in the secondary cell and the beam report associated with the second event triggered in the secondary cell, according to the priority rules. Since the second event has a higher priority than the first event in the same type of cell, the terminal device can prioritize reporting the beam report associated with the second event triggered in the secondary cell, and then report the beam report associated with the first event triggered in the secondary cell.

[0204] For example, the terminal device can sequentially report beam reports associated with the second event triggered in secondary cell A, the second event triggered in secondary cell C, the first event triggered in secondary cell C, and the first event triggered in secondary cell B, according to priority rules and preset order.

[0205] Finally, since no third event was triggered in the primary cell, the terminal device can report the third event associated with the third event triggered in the secondary cell according to priority rules. For example, the terminal device can report the beam report associated with the third event triggered in secondary cell C, the beam report associated with the third event triggered in secondary cell B, and the beam report associated with the third event triggered in secondary cell A in a preset order.

[0206] Compared to Embodiment 4, this embodiment adjusts the priority of third events triggered in the primary cell and third events triggered in the secondary cell. Critical events triggered in the primary cell, such as the first and second events, are reported first, followed by critical events triggered in the secondary cell, such as the first and second events.

[0207] In some embodiments, considering the transmission requirements of service data, a secondary cell triggers a first event indicating that the quality of the current beam in the secondary cell has deteriorated. To prevent the quality of the current beam from continuing to deteriorate and causing a connection interruption, the first event has the highest priority among the first and second events triggered in the secondary cell. Therefore, the priority rule can be: the first and second events triggered in the primary cell have higher priority than the first and second events triggered in the secondary cell; the first and second events triggered in the secondary cell have higher priority than the third event triggered in the primary cell; the third event triggered in the primary cell has higher priority than the third event triggered in the secondary cell; for the first and second events triggered in the primary cell, the second event has higher priority than the first event; for the first and second events triggered in the secondary cell, the first event has higher priority than the second event.

[0208] As can be seen, in this embodiment of the application, when the terminal device detects that multiple events have been triggered, it can report beam reports associated with the multiple events to the network device according to priority rules. This avoids uplink resource contention and signaling conflicts caused by simultaneously reporting beam reports associated with multiple events, and also avoids the impact on data transmission caused by reporting in random order.

[0209] In this application, the beam report reported by the terminal device can be understood as the terminal device reporting a beam report to the network device. Here, "reporting" can be understood as "sending".

[0210] In some embodiments, the terminal device may report event-related beam reports to the network device via the physical uplink control channel (PUCCH) and the physical uplink shared channel (PUSCH).

[0211] In other embodiments, the terminal device may report the beam report associated with the event to the network device only via PUCCH.

[0212] Taking the terminal device (UE) and the network device (gNB) as an example, such as Figure 4 As shown, the UE detects multiple events and sorts them according to a priority rule. This priority rule can be any one of the rules shown in Tables 1-9. Then, the UE sequentially reports the beam reports associated with the events to the gNB according to the sorting result. For example, the UE sends the beam report associated with the highest priority event to the gNB via PUCCH, then sends the beam report associated with the second highest priority event via PUCCH, and so on, until the UE sends the beam report associated with the lowest priority event via PUCCH. Optionally, the UE sends the above beam reports to the gNB via both PUCCH and PUSCH.

[0213] As can be seen, this application prioritizes multiple events in conflict scenarios by comprehensively considering factors such as cell type, event type, and beam quality. This ensures that high-priority events, i.e., critical events, are reported and processed first, while low-priority events are reported later, thereby guaranteeing efficient beam switching, avoiding unnecessary signaling overhead, and saving signaling resources.
