Abstract
Description
Technical Field
[0001] Embodiments of the present application relate to the field of communication technologies, and in particular, to a method for reporting beam reports and a communication device. Background Art
[0002] Carrier Aggregation (CA) technology is a key technology in the field of communication. CA technology realizes higher data transmission rates and more flexible spectrum allocation by aggregating multiple component carriers (CCs).
[0003] In a scenario of communication based on CA technology, when a terminal device detects that multiple events are triggered, there is currently no clear event reporting mechanism. Among them, the multiple events may include, for example, events for triggering relevant processes for switching to an alternative beam, events for triggering beam switching, or events for triggering an update of an alternative beam list. Some terminal devices will report beam reports associated with these multiple events simultaneously, which will lead to uplink resource competition and signaling conflicts. Some terminal devices will report beam reports associated with these multiple events in a random order, which will cause the processing of key events to be delayed, and may thus affect data transmission. Summary of the Invention
[0004] Embodiments of the present application provide a method for reporting beam reports and a communication device, which can report beam reports associated with multiple events based on a priority rule, and can not only avoid the problems of uplink resource competition and signaling conflicts caused by simultaneous reporting, but also avoid the problem of delay in processing key events caused by reporting in a random order.
[0005] To achieve the above object, the embodiments of the present application adopt the following technical solutions: In a first aspect, a method for reporting beam reports is provided, which is applied to a network device. The method includes: detecting that multiple events are triggered, and reporting beam reports associated with the multiple events according to a priority rule; where 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.
[0006] In the present application, when a terminal device detects that multiple events are triggered, the terminal device can report beam reports associated with the multiple events to the network device according to a priority rule, which can avoid uplink resource competition and signaling conflicts caused by simultaneous reporting, and can also avoid the impact on the timeliness of beam switching caused by reporting in a random order.
[0007] In a possible implementation of the first aspect, the priority rule is that 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. The first event is that the quality of the first beam is lower than 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; the third event is that the quality of at least one third beam is higher than the quality of a reference signal by a threshold.
[0008] The first beam is the currently serving beam.
[0009] The second beam is the beam to replace the first beam to provide service. Exemplarily, the network device will select one of the at least one second beam reported by the terminal device and instruct the terminal device to use the second beam selected by the network device to replace the first beam to provide service.
[0010] 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 Qth state in the active TCI state list, where Q is a positive integer.
[0011] The first event aims to report the potential risk of the current beam quality degradation, trigger the alternative beam handover, and avoid connection interruption caused by too 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 the timeliness of the list. Considering the requirement of improving communication performance, 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.
[0012] In a possible implementation of the first aspect, the events triggered in the primary cell are preferentially processed, and the priority rule includes: 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. For the same type of events triggered in both the primary cell and the secondary cell, the priority of the event triggered in the primary cell is higher than that of the event triggered in the secondary cell. For example, for the first event triggered in both the primary cell and the secondary cell, the priority of the first event triggered in the primary cell is higher than that of the first event triggered in the secondary cell.
[0013] In a possible implementation of the first aspect, events triggered in the secondary cell are preferentially processed. The priority rules include: 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. For the same type of event triggered in both the primary cell and the secondary cell, the priority of the event triggered in the secondary cell is higher than that of the event triggered in the primary cell. For example, for the first event triggered in both the primary cell and the secondary cell, the priority of the first event triggered in the secondary cell is higher than that of the first event triggered in the primary cell.
[0014] In a possible implementation of the first aspect, considering the transmission requirements of the control signaling of the primary cell and the improvement of the communication performance of the secondary cell, the priority rules include: 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. For the first event or the third event triggered in both the primary cell and the secondary cell, the priority of the event triggered in the primary cell is higher than that of the event triggered in the secondary cell. For the second event triggered in both the primary cell and the secondary cell, the priority of the second event triggered in the secondary cell is higher than that of the second event triggered in the secondary cell.
[0015] In a possible implementation of the first aspect, the priority rule is: the priority of the first event is higher than that of the second event, and the priority of the second event is higher than that of the third event. When the first event is triggered in a cell, it indicates that the quality of the first beam of the cell is poor. In this case, to avoid the continuous deterioration of the quality of the first beam of the cell resulting in connection interruption, when multiple events are triggered, the priority of the first event is the highest. Since the second event aims to use a beam with better quality to provide services, that is, the second event aims to improve the communication performance, and the third event aims to update the alternative beam list, therefore, considering the need to improve the communication performance, the priority of the second event is higher than that of the third event.
[0016] In a possible implementation of the first aspect, giving priority to the transmission requirements of the control signaling of the primary cell, the priority rules include: the priority of the first event is higher than that of the second event, and the priority of the second event is higher than that of the third event. For the same type of event triggered in both the primary cell and the secondary cell, the priority of the event triggered in the primary cell is higher than that of the event triggered in the secondary cell.
[0017] In a possible implementation of the first aspect, the transmission requirements of the secondary cell's service data are prioritized. The priority rules are as follows: The priority of the first event is higher than that of the second event, and the priority of the second event is higher than that of the third event. For the same type of event triggered in both the primary cell and the secondary cell, the priority of the event triggered in the secondary cell is higher than that of the event triggered in the primary cell.
[0018] In a possible implementation of the first aspect, considering both the transmission requirements of the primary cell's control signaling and the improvement of the secondary cell's communication performance, the priority rules are as follows: The priority of the first event is higher than that of the second event, and the priority of the second event is higher than that of the third event. For the first event or the third event triggered in both the primary cell and the secondary cell, the priority of the event triggered in the primary cell is higher than that of the event triggered in the secondary cell. For the second event triggered in both the primary cell and the secondary cell, the priority of the second event triggered in the secondary cell is higher than that of the second event triggered in the secondary cell.
[0019] In a possible implementation of the first aspect, when multiple triggered events include multiple first events, the worse the quality of the first beam, the higher the priority of the first event. The first event is intended to report the potential risk of the current beam quality degradation. The worse the quality of the first beam, the greater the risk of the current beam quality degradation. When multiple first events are triggered, the worse the quality of the first beam, the more priority is given to reporting the beam report associated with the first event.
[0020] In a possible implementation of the first aspect, when multiple triggered events include multiple second events, the better the quality of at least one second beam, the higher the priority of the second event. The second event is intended 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 more priority is given to reporting the beam report associated with the second event.
[0021] In a possible implementation of the first aspect, when multiple triggered events include multiple third events, the better the quality of at least one third beam, the higher the priority of the third event. The third event is intended to update and maintain the alternative beam list to ensure the timeliness of the list. Therefore, when multiple third events are triggered, the better the quality of at least one third beam, the more priority is given to reporting the beam report associated with the third event.
[0022] In a possible implementation of the first aspect, the priority rule is that the priority of an event triggered in the primary cell is higher than the priority of an event triggered in the secondary cell. Since the primary cell carries the transmission of control signaling for all cells, the event triggered in the primary cell is more critical and important. Therefore, considering the transmission requirements of control signaling, the priority of an event triggered in the primary cell is higher than the priority of an event triggered in the secondary cell.
[0023] In a possible implementation of the first aspect, the priority rule is that the priority of an event triggered in the primary cell is higher than the priority of an event triggered in the secondary cell; for different types of events triggered in the same type of cell, 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. Since the primary cell carries the transmission of control signaling for all cells, the event triggered in the primary cell is more critical and important. Therefore, considering the transmission requirements of control signaling, 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 same type of cell, when the events triggered in the cell include multiple types, 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.
[0024] In a possible implementation of the first aspect, the priority rule is that the priority of an event triggered in the primary cell is higher than the priority of an event triggered in the secondary cell; for different types of events triggered in the same type of cell, 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. Since the primary cell carries the transmission of control signaling for all cells, the event triggered in the primary cell is more critical and important. Therefore, considering the transmission requirements of control signaling, 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 primary cell or the secondary cell, when the events triggered in the cell include multiple types, the priority of the first event is higher than the priority of the second event, and the priority of the first event is higher than the priority of the third event.
[0025] In a possible implementation of the first aspect, the priority rule includes: the priority of an event triggered in the primary cell is higher than the priority of an event triggered in the secondary cell; for an event triggered in the primary cell, 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 an event triggered in the secondary cell, 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.
[0026] In a possible implementation of the first aspect, the priority rules include: the priorities of the first event and the second event triggered in the primary cell are higher than those of the first event and the second event triggered in the secondary cell; the priorities of the first event and the second event triggered in the secondary cell are higher than those of the third event triggered in the primary cell; the priority of the third event triggered in the primary cell is higher than that of the third event triggered in the secondary cell; for the first event and the second event triggered in the same type of cell, the priority of the second event is higher than that of the first event.
[0027] In a possible implementation of the first aspect, the priority rules include: the priorities of the first event and the second event triggered in the primary cell are higher than those of the first event and the second event triggered in the secondary cell; the priorities of the first event and the second event triggered in the secondary cell are higher than those of the third event triggered in the primary cell; the priority of the third event triggered in the primary cell is higher than that of the third event triggered in the secondary cell; for the first event and the second event triggered in the primary cell, the priority of the second event is higher than that of the first event; for the first event and the second event triggered in the secondary cell, the priority of the first event is higher than that of the second event.
[0028] In a possible implementation of the first aspect, the same type of event can be triggered in multiple secondary cells. When the triggered event is the first event, the worse the quality of the first beam, the higher the priority of the first event. When the triggered event is the 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 the third event, the better the quality of at least one third beam, the higher the priority of the third event.
[0029] In a possible implementation of the first aspect, the beam report associated with the first event includes: the identifier of the first event, the identifier and quality of the first beam. The beam report associated with the second event includes: the identifier of the second event, the identifiers and quality of at least one second beam. The beam report associated with the third event includes: the identifier of the third event, the identifiers and quality of at least one third beam. Among them, when there are multiple second beams, the identifiers and quality of the multiple second beams are sorted in descending order of quality in the corresponding beam report. When there are multiple third beams, the identifiers and quality of the multiple third beams are sorted in descending order of quality in the corresponding beam report.

[0041] Please refer to Figure 1 , Figure 1 which is a schematic diagram of the architecture of a communication system provided by an embodiment of this application. As Figure 1 shown, the communication system provided by an embodiment of this application may include: a network device 10 and a terminal device 20. The network device 10 and the terminal device 20 can communicate via beams.
[0042] The above-mentioned network device may be a device that makes decisions and processes terminal devices. For example, the network device 10 can manage beams. For example, the network device 10 configures beams for the terminal device 20, or switches beams based on the measurement report of the beams reported by the terminal device, etc.
[0043] The network device 10 in this application can be an access network device. An access network device is sometimes also referred to as an access node. The access network device has a wireless transceiver function for communicating with terminal devices. The access network device includes, but is not limited to, the base station in the above communication system, evolved NodeB (eNodeB), transmission reception point (TRP), next-generation NodeB (gNB) in the 5G mobile communication system, access network device or module of the open RAN system, satellite in the NTN communication system, base station in the future mobile communication system, or access node in the WiFi system, etc. The access network device can also be a module or unit capable of implementing some functions of the base station.

Optionally, the access network device can also be a server, wearable device, or vehicle-mounted device, etc. For example, the access network device in vehicle to everything (V2X) technology can be a road side unit (RSU). Multiple access network devices in the communication system can be of the same type of base station or different types of base stations. The base station can communicate with the terminal device or communicate with the terminal device through a relay station. The terminal device can communicate with multiple base stations in different access technologies. The specific technologies and specific device forms adopted by the access network device are not limited in the embodiments of this application. In this application, the access network device is abbreviated as the network device.
[0044] The terminal device 20 in the embodiments of the present application can transmit data with the network device 10 through beams. The terminal device in the present application can be a wireless terminal device capable of receiving scheduling and indication information of the network device. The wireless terminal device can be a device that provides voice and / or data connectivity to users, or a handheld device with wireless connection capabilities, 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 through a radio access network (RAN).

The access network device and / or the terminal device can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface; can also be deployed on airplanes, balloons, and artificial satellites in the air.

For example, the access network device and the terminal device are both deployed on land; or, the access network device is deployed on land and the terminal device is deployed on the water surface, etc., and will not be listed one by one.
[0046] In practical applications, multiple network devices can cooperate to assist a terminal in achieving wireless access, and different network devices respectively implement some functions of a base station. For example, a network device can be a central unit (CU), a distributed unit (DU), a CU-control plane (CP), a CU-user plane (UP), or a radio unit (RU), etc. The CU and the DU can be set separately, or can also be included in the same network element, such as a baseband unit (BBU). The RU can be included in a radio frequency device or a radio frequency unit, such as included in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH).
[0047] In different systems, the CU (or CU-CP and CU-UP), the DU, or the RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, the CU can also be called an O-CU (open CU), the DU can also be called an O-DU, the CU-CP can also be called an O-CU-CP, the CU-UP can also be called an O-CU-UP, and the RU can also be called an O-RU. Any one of the CU (or CU-CP, CU-UP), the DU, and the RU in this application can be implemented through a software module, a hardware module, or a combination of a software module and a hardware module. The CU (or CU-CP and CU-UP), the DU, and the RU can implement different protocol layer functions.
[0048] To facilitate the understanding of the embodiments of this application, the terms involved in this application will be briefly described first. Optionally, the explanations of some terms can also refer to the explanations in the 3rd generation partnership project (3GPP) standard protocol.
[0049] CA technology: Refers to carrier aggregation technology, which is a key technology in the field of communication. CA technology realizes higher data transmission rates and more flexible spectrum allocation by aggregating multiple CCs. Exemplarily, CA technology aggregates two or more component carriers together to obtain a larger bandwidth. Among them, two or more component carriers include a primary component carrier (PCC) and multiple secondary component carriers (SCCs). One primary component carrier corresponds to one primary cell (PCell), and multiple secondary component carriers correspond to multiple secondary cells (SCells). The primary component carrier is used to carry the signaling transmission of all cells, including the primary cell and the secondary cells. The secondary component carrier is used to carry the transmission of service data.
[0050] It should be understood that the technical terms in this application are only examples and not limitations. For example, with the evolution of technology, the technical terms will also change. In the case of the same technical meaning, other technical terms should also apply to this application.
[0051] According to the provisions of the standard protocol, the network device can configure multiple events for the terminal device and configure different channel state information-report configuration identifiers (CSI-ReportConfigID) for different events. Exemplarily, the network device can configure multiple events for the terminal device through radio resource control signaling (RRC signaling). For example, the RRC signaling includes the identification of the cell and the configuration related to beam measurement. The terminal device can perform the specified type of beam measurement on the specified cell according to the configuration of the network device, and report the beam report corresponding to the triggered event(s) to the network device when one or more events are detected to be triggered. Exemplarily, the terminal device reports the beam report associated with the one or more events to the network device through the first physical uplink control channel and / or the second physical uplink shared channel. Among them, there is no corresponding relationship between the type of event and the first physical uplink control channel and / or the second physical uplink shared channel.
[0052] In a scenario of communication based on CA technology, when a terminal device detects that multiple events are triggered, there is currently no clear reporting mechanism. Among them, the multiple events may include, for example, events for triggering processes related to switching to an alternative beam, events for triggering beam switching, and events for triggering an update of the alternative beam list. Some terminal devices will report beam reports associated with these multiple events simultaneously, which will lead to uplink resource competition and signaling conflicts. Some terminal devices will report beam reports associated with these multiple events in a random order. If the beam report associated with a non-critical event is reported first and the beam report associated with a critical event is reported later, the processing of the critical event will be delayed, which may further affect the timeliness of beam switching and thus may affect data transmission.
[0053] Among them, the multiple events include Event-1, Event-2, and Event-7.
[0054] Event-1 is that the quality of the current beam is lower than a threshold. Event-2 is that the quality of at least one new beam is higher than the quality of the current beam by a threshold. Event-7 is that the quality of at least one new beam is higher than the quality of a reference signal by a threshold. The reference signal may be, for example, the Qth reference signal in the alternative beam list. The alternative beam list may be, for example, an active transmission configuration indicator (TCI) state list, and the Qth reference signal may specifically be the reference signal corresponding to the Qth state in the active TCI state list.
[0055] For example, a terminal device detects that Event-2 and Event-7 are triggered in a certain cell, such as the primary cell or the 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 to the network device, the network device will first trigger the process of updating the alternative beam list and then trigger the beam switching process. And Event-2 aims to achieve a fast switch 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 triggered late, resulting in a delay in the fast switch to the high-quality new beam.
[0056] For another example, the terminal device detects that events are triggered in multiple cells. For example, the terminal device detects that event 1 is triggered in the primary cell and event 7 is triggered in the secondary cell. If the terminal device first reports a beam report associated with event 7 triggered in the secondary cell to the network device and then reports a 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 of the primary cell may continue to deteriorate, triggering the beam failure recovery mechanism. Since the primary cell is responsible for transmitting the control signaling of all cells (including the secondary cells of the primary cell), the quality of the current beam of the primary cell directly affects the connection status between the terminal device and the network device. The 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.
[0057] In view of this, an embodiment of the present application provides a method for reporting a beam report. When the terminal device detects that multiple events are triggered, the terminal device can report beam reports associated with the multiple events to the network device according to the priority rule, which can avoid the uplink resource competition and signaling conflict caused by reporting beam reports associated with events simultaneously, and can also avoid the impact on the timeliness of beam switching caused by reporting in a random order.
[0058] The solution provided by the present application will be described in detail below in conjunction with the corresponding flowchart. It can be understood that in the schematic flowchart provided by the present application, different devices (for example, the terminal device, the network device) are mainly used as the execution subjects of the interaction schematic to illustrate the method, but the present application does not limit the execution subjects of the interaction schematic. For example, the devices (for example, the terminal device, the network device) in the schematic flowchart can also be chips, chip systems, or processors that support the device to implement the method, and can also be logic modules or software that can implement all or part of the functions of the device.
[0059] A unified description is made here. In the interaction process of the embodiment of the present application, the message or signaling interaction involved can adopt the messages or signaling in the standard, or can be newly introduced messages or signaling. The embodiment of the present application does not make specific limitations on this.
[0060] The embodiment of the present application will use Figure 1 The network device 10 and the terminal device 20 in the shown communication system as an example, and in combination with the accompanying drawings and application scenarios, a method for reporting a beam report provided by the embodiment of the present application will be elaborated in detail. This method is executed by the cooperation of the network device and the terminal device.
[0061] In the embodiment of the present application, both the primary cell and the secondary cell of the terminal device can be referred to as the cells of the terminal device, or can be referred to as the cells that provide services for the terminal device.
[0062] In the embodiments of the present application, the events include a first event, a second event, and a third event.
[0063] The first event is that the quality of the first beam is lower than a threshold. The first beam is the current beam, that is, the beam currently providing services. In other words, the current beam is the beam in the cell that currently provides services to the terminal device, that is, the terminal device and the network device transmit data through the current beam of the cell. The data can be signaling or service data. It should be understood that each cell, such as the primary cell or the secondary cell, has a corresponding current beam. The current beam of the cell changes dynamically. For example, the network device covers the cell through multiple (directional) beams, the terminal device can perform beam measurements based on the configuration of the network device, and report the results of the beam measurements to the network device. The network device dynamically adjusts the current beam of the cell based on the results of the beam measurements reported by the terminal device. The cell covers its service area through multiple beams, and the terminal device dynamically selects the current beam based on the quality of the multiple beams in the cell. The quality of the beam can be characterized by the value of a parameter. The parameter can be, for example, the reference signal received power (RSRP), the reference signal received quality (RSRQ), the signal to interference plus noise ratio (SINR), etc. Among them, the RSRP can be the 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 taken from the numerical range specified by the standard protocol. In some embodiments, the threshold can be pre-stored in the terminal device.
[0064] 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 to provide services. The second beam can be alternatively described as a new beam, a candidate beam, or an adjacent beam, etc. In other words, the second event is an event in which there is at least one second beam whose quality is higher than the quality of the first beam by a threshold. Among them, the quality of the second beam being 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 taken from the numerical range specified by the standard protocol. In some embodiments, the threshold can be pre-stored in the terminal device.
[0065] The third event is that the quality of at least one third beam is higher than a threshold of the quality of a reference signal. The third beam can alternatively be described as a new beam. In other words, the third event is an event where there exists at least one third beam whose quality is higher than a threshold of the quality of a reference signal. Among them, the quality of the third beam being higher than a threshold of the quality of the reference signal 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.
[0066] The reference signal is the Qth reference signal with the best quality in the list of candidate beams. The list of candidate beams can be a list of active TCI states. The list of active TCI states includes multiple states, and each state corresponds to a reference signal. The multiple states are sorted in descending order of the quality of the reference signals. 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 a beam to be configured into the list of active TCI states. Among them, being configured into the list of active TCI states can be understood as activating the state corresponding to the third beam. For example, activating m states corresponding to m third beams. Correspondingly, since the number of active states in the TCI state list is fixed, after activating m states, the m states with the worst quality in the active TCI state list will also be deactivated.
[0067] It should be understood that the network device configures a list of active TCI states for each cell of the terminal device. In some embodiments, the third event can be an Event-7 event. In some embodiments, the threshold can be taken within the numerical range specified by the standard protocol. In some embodiments, the threshold can be pre-stored in the terminal device.
[0068] Among them, the values of the thresholds in the first event, the second event, and the third event can be different from each other, or, the values of the thresholds in the first event, the second event, and the third event can be partially or entirely the same.
[0069] In the embodiments of the present application, the network device configures the above-mentioned first event, second event, and third event for the terminal device. The terminal device can periodically measure the quality of the beams in each cell, and based on the measurement results of the quality of the beams in each cell, determine whether to trigger one or more of the first event, the second event, or the third event. It should be understood that the network device covers the cell with multiple (directional) beams. The beams of the cell include the current beam and other beams except the current beam among the multiple beams. The terminal device periodically detecting the quality of the beams in each cell can be understood as: the terminal device periodically detecting the quality of the current beam and the quality of other beams except the current beam in each cell.
[0070] In the embodiments of the present application, when the terminal device detects that an event is triggered, the terminal device may report a beam report associated with the event to the network device. The network device will trigger a corresponding process based on the beam report reported by the terminal device. For example, the network device triggers a related process of switching to an alternative beam in response to the beam report associated with the first event reported by the terminal device. The network device triggers a beam switching process in response to the beam report associated with the second event reported by the terminal device. The network device triggers an update process of the alternative beam list in response to the beam report associated with the third event reported by the terminal device. It can be seen that the first event is intended to report the potential risk of the degradation of the current beam quality, trigger the switching of the alternative beam, and avoid the connection interruption caused by the too low quality of the current beam. The second event is intended to quickly switch to a new beam with better quality to improve the communication performance. The third event is intended to update and maintain the alternative beam list to ensure the timeliness of the list.
[0071] Figure 2 A method for reporting a beam report provided by an embodiment of the present application may include: S1. The network device configures a first event, a second event, and a third event for the terminal device.
[0072] S2. When detecting that multiple events are triggered, the terminal device reports a beam report associated with the multiple events to the network device according to the priority rule.
[0073] Wherein, the beam report associated with the multiple events includes at least one type of beam report among the beam report associated with the first event, the beam report associated with the second event, and the beam report associated with the third event.
[0074] In some embodiments, the beam report associated with the first event may include: an identifier of the first event, an identifier and quality of the first beam. Wherein, the quality of the first beam may be characterized by the value of RSRP, and the RSRP value may specifically be the value of L1-RSRP or the absolute value of L1-RSRP. The identifier of the first beam may specifically be a resource indicator of the downlink reference signal corresponding to the first beam (DL RS resource indicator). The identifier of the first event may be, for example, the event type of the first event.
[0075] In some embodiments, the beam report associated with the second event includes: an identifier of the second event, identifiers and quality of at least one second beam. Wherein, the identifier of the second event may be the type of the second event.
[0076] Exemplarily, the beam report associated with the second event includes: the identification of the second event, the identifications and qualities of N beams. Among them, 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}.
[0077] When the number of beams that meet the triggering condition 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 with the best qualities among the beams that meet the triggering condition of the second event. That is to say, when there are multiple beams that meet the triggering condition of the second event, the terminal device only reports the information of the top N beams with the best qualities among the multiple beams to the network device, and discards the information of the remaining beams to reduce signaling overhead. Among them, the beam that meets the triggering condition of the second event is a beam whose quality is higher than a threshold of the quality of the first beam, that is, the second beam.
[0078] When the number of beams that meet the triggering condition of the second event is less than N, the N beams in the beam report associated with the second event are the beams that meet the triggering condition of the second event and the beams that do not meet the triggering condition of the second event. Among them, the total number of the beams that meet the triggering condition of the second event and the beams that do not meet the triggering condition of the second event is N. The beam that does not meet the triggering condition of the second event is a beam whose quality is not 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 is used to indicate the beams that meet the triggering condition of the second event among the N beams, that is, to indicate the second beams among the N beams. Exemplarily, the network device decides whether to enable configuration information, such as a first preset field in the RRC signaling, according to 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.
[0079] When the number of beams that meet the triggering condition of the second event is equal to N, the N beams in the beam report associated with the second event are the N beams that meet the triggering condition of the second event.
[0080] Taking N equal to 7 as an example, for example, there are 8 beams in a cell, such as the primary cell or the secondary cell, whose quality is higher than a threshold of the quality of the first beam. The corresponding beam report includes the identifications and qualities of the top 7 beams with the best qualities among these 8 beams. Another example is that there are 4 beams in a cell, such as the primary cell or the secondary cell, whose quality is higher than a threshold of the quality of the first beam. The corresponding beam report includes the identifications and qualities of these 4 beams and 3 beams whose quality is not higher than a threshold of the quality of the first beam.
[0081] In some embodiments, the identifiers and qualities of at least one second beam are sorted from high to low according to quality in the beam report. Exemplarily, the beam report may include information on N groups of beams, and the information of a group of beams includes the identifier of a beam and the quality of the beam. The information of these N groups of beams is arranged in sequence in the beam report in the order of the quality of the beams from high to low. Among them, the N beams may be n second beams and N - n beams whose qualities are not 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.
[0082] Optionally, the beam report associated with the second event may further include the identifier and quality of the first beam. Exemplarily, when the second preset field in the configuration information (such as RRC signaling) sent by the network device is enabled, the beam report associated with the second event reported by the terminal device to the network device may further include the identifier and quality of the current beam, i.e., the first beam.
[0083] In some embodiments, the beam report associated with the third event includes: the identifier of the third event, the identifiers and qualities of at least one third beam. Among them, the identifier of the third event may be the type of the third event.
[0084] Exemplarily, the beam report associated with the third event includes: the identifier of the third event, the identifiers and qualities of M beams. Among them, 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}.
[0085] When the number of beams that meet 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 with the best quality among the beams that meet the triggering condition of the third event. That is to say, when there are multiple beams that meet the triggering condition of the third event, the terminal device only reports the information of the top M beams with the best quality among the multiple beams to the network device, and discards the information of the remaining beams to reduce signaling overhead. Among them, the beams that meet the triggering condition of the third event are the beams whose quality is higher than a threshold of the quality of the reference signal, i.e., the third beams.
[0086] When the number of beams that meet the triggering condition of the third event is less than M, the M beams in the beam report associated with the third event are the beams that meet the triggering condition of the third event and the beams that do not meet the triggering condition of the third event, where the total number of the beams that meet the triggering condition of the third event and the beams that do not meet the triggering condition of the third event is M. The beams that do not meet the triggering condition of the third event are the beams whose quality is not higher than a threshold of the quality of the reference signal. In this case, indication information is also carried in the beam report associated with the third event, and the indication information is used to indicate the beams that meet the triggering condition of the third event among the M beams, that is, to indicate the third beams among the M beams. Exemplarily, the network device determines whether to enable a configuration information, such as a third preset field in the RRC signaling, according to 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 further include the indication information.
[0087] When the number of beams that meet the triggering condition of the third event is equal to M, the M beams in the beam report associated with the third event are the M beams that meet the triggering condition of the third event.
[0088] Taking M equal to 6 as an example, for example, there are 9 beams in a cell, such as a primary cell or a secondary cell, whose quality is higher than a threshold of the quality of the reference signal. The corresponding beam report includes the identifiers and qualities of the top 6 beams with the best quality among these 9 beams. For another example, there are 3 beams in a cell, such as a primary cell or a secondary cell, whose quality is higher than a threshold of the quality of the reference signal. The corresponding beam report includes the identifiers and qualities of these 3 beams and 3 beams whose quality is not higher than a threshold of the reference quality.
[0089] In some embodiments, the identifiers and qualities of the M beams are sorted from high to low in quality in the beam report. Exemplarily, the beam report may include information on M groups of beams, and a group of beam information includes the identifier of a beam and the quality of the beam. The information on these M groups of beams is arranged in sequence in the beam report in the order of the quality of the beams from high to low. Among them, these M beams may be m third beams and M - m beams whose quality is not higher than a threshold of the quality of the reference signal, where m is greater than or equal to 1 and less than or equal to M.
[0090] Optionally, the beam report associated with the third event further includes the identifier and quality of the Qth reference signal in the activated TCI state list. Exemplarily, when a fourth preset field in the 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 activated TCI state list.
[0091] Among them, the quality of the beams, such as the N beams or M beams in the foregoing text, can be characterized by the value of RSRP. The value of RSRP can specifically be the value of L1-RSRP or the absolute value of L1-RSRP. In some embodiments, the quality of the beam with the best quality among the N beams or M beams can be characterized by the value of RSRP, and the quality of the remaining N-1 beams or M-1 beams can be characterized by the differential value of L1-RSRP. Among them, the differential L1-RSRP is the difference between the value of L1-RSRP of the beam and the value of L1-RSRP of the beam with the best quality. The identifier of the beam, such as the N beams or M beams, can specifically be the resource indicator of the downlink reference signal (DL RS resource indicator) corresponding to the beam. The resource indicator of the downlink reference signal of the beam corresponds one-to-one with the beam and is used for the terminal device to measure the corresponding beam.
[0092] In some embodiments, when the terminal device detects that only one event is triggered in one cell, the terminal device may report a beam report associated with this one event to the network device. This scenario can be referred to as a single-cell single-event scenario. Among them, this one event can be any one of the first event, the second event, or the third event.
[0093] In some other embodiments, when the terminal device detects that at least two types of events among the first event, the second event, or the third event are triggered in only one cell, the terminal device may report a beam report associated with these at least two types of events to the network device based on the priority rule. Among them, the priority rule is: 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 example, when the terminal device detects that the first event, the second event, and the third event are triggered in one cell, based on the priority rule, the terminal device first reports the beam report associated with the second event to the network device, 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. This scenario can be referred to as a single-cell multi-event scenario.
[0094] In some other embodiments, when the terminal device detects that one event is triggered in multiple cells, the terminal device may report a beam report associated with the event to the network device according to the priority rule. Among them, the types of the one event triggered in multiple cells can be the same or different. This scenario can be referred to as a multi-cell single-event scenario.
[0095] In some other embodiments, when the terminal device detects that at least two types of events among the first event, the second event, or the third event are triggered in multiple cells, the terminal device may report a beam report associated with the event to the network device according to the priority rule. This scenario can be referred to as a multi-cell multi-event scenario.
[0096] The following will introduce in combination with specific embodiments and will not be elaborated here.
[0097] Among them, the 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 the triggered events include a first event, a second event, and a third event. The types of the cells corresponding to the triggered events include a primary cell and a secondary cell. The cell corresponding to the triggered event can be understood as the cell that triggers the event, or the event is triggered in this cell. Exemplarily, if the cell corresponding to the triggered event is a primary cell, it can be understood that the cell that triggers the event is a primary cell, or in other words, the event is triggered in the primary cell.
[0098] The following will introduce in combination with specific embodiments.
[0099] Embodiment 1: The priority rules are related to the type of the triggered event.
[0100] 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.
[0101] Table 1
[0102] When multiple events are detected to be triggered, the terminal device can report the beam reports associated with the multiple events to the network device according to the priority rules shown in Table 1.
[0103] Exemplarily, when the multiple triggered events include the first event, the second event, and the third event, the terminal device preferentially reports the beam report associated with the second event to the network device according to the priority rules, 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.
[0104] Another example is that when the multiple triggered events include at least two types of events among the first event, the second event, and the third event, the terminal device reports the beam reports associated with the multiple events in sequence according to the priority rules shown in Table 1. For example, when the multiple triggered events include the first event and the second event, the terminal device preferentially reports the beam report associated with the second event to the network device according to the priority rules, and then reports the beam report associated with the first event to the network device.
[0105] 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 multiple triggered events include multiple second events, the terminal device may report multiple beam reports associated with the multiple second events in a random order.
[0106] It should be understood that a cell may trigger multiple types of events simultaneously. For example, a cell may trigger at least one type of event among the first event, the second event, or the third event simultaneously. For events of the same type, a cell can only be triggered once at a moment.
[0107] Exemplarily, taking the cell that provides services to the terminal device including the primary cell, secondary cell A, secondary cell B, and secondary cell C as an example. The terminal device detects that the first event and the second event are triggered in the primary cell, the second event and the third event are triggered in secondary cell A, the first event and the third event are triggered in secondary cell B, and the first event, the second event, and the third event are triggered in secondary cell C.
[0108] The terminal device may preferentially report multiple beam reports associated with the multiple second events in a random order. For example, the terminal device may report the beam report associated with the second event triggered in the primary cell, the beam report associated with the second event triggered in secondary cell A, and the beam report associated with the second event triggered in secondary cell C in a random order. Then, the terminal device may report multiple beam reports associated with the multiple first events in a random order. For example, the terminal device may report the beam report associated with the first event triggered in the primary cell, the beam report associated with the first event triggered in secondary cell B, and the beam report associated with the first event triggered in secondary cell C in a random order. Finally, the terminal device may report multiple beam reports associated with the multiple third events in a random order. For example, the terminal device may report the beam report associated with the third event triggered in secondary cell A, 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 C in a random order.
[0109] In some other 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 preset order.
[0110] Exemplarily, in the case where multiple triggered events include multiple first events, the terminal device may report multiple beam reports associated with the multiple first events according to the quality of the first beam. For example, the worse the quality of the first beam, the higher the priority of the corresponding first event, that is, the beam report associated with the event is reported preferentially. In other words, in the case where multiple first events are triggered, the terminal device reports multiple beam reports associated with the multiple first events in ascending order of the quality of the first beam.
[0111] Also exemplarily, in the case where 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 beam. For example, the better the quality of the n second beams, the higher the priority of the second event, that is, the beam report associated with the event is reported preferentially. Wherein, the quality of the n second beams can be represented by the average value of the quality of the n second beams. The larger the average value of the quality of the n second beams, the better the quality of the n second beams. In other words, in the case where multiple second events are triggered, the terminal device reports the beam reports associated with the second events triggered in the corresponding cell in descending order of the average value of the quality of the n second beams in the cell.
[0112] Also exemplarily, in the case where 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 the m third beams in the cell. For example, the better the quality of the m third beams, the higher the priority of the third event, that is, the beam report associated with the event is reported preferentially. Wherein, the quality of the m third beams can be represented by the average value of the quality of the m third beams. The larger the average value of the quality of the m third beams, the better the quality of the m third beams. In other words, in the case where multiple third events are triggered, the terminal device reports the beam reports associated with the third events triggered in the corresponding cell in descending order of the average value of the quality of the m third beams in the cell.
[0113] For example, in the case where multiple first events, second events, and third events are triggered, the priority rules are shown in Table 2. Specifically, the priority of multiple second events arranged in descending order of the average value of the quality of the n second beams is higher than the priority of multiple first events arranged in ascending order of the quality of the first beam; the priority of multiple first events arranged in ascending order of the quality of the first beam is higher than the priority of multiple third events arranged in descending order of the average value of the quality of the m third beams.
[0114] Table 2
[0115] Continuing with the example in the previous text, the terminal device can, based on the priority rule, preferentially report beam reports associated with the second event. Since the second event is 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 mean value of the quality of the n second beams in the cell. Taking the beam quality as RSRP as an example, the mean value of the RSRP of the n second beams in the primary cell is -60 dBm, the mean value of the RSRP of the n second beams in secondary cell A is -50 dBm, and the mean value of the RSRP of the n second beams in secondary cell C is -75 dBm. Then, 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.
[0116] Next, the terminal device can, based on the priority rule, report the beam report associated with the first event. Since the first event is triggered in multiple cells, the terminal device can report the corresponding beam reports in ascending order of the first beam quality. Taking the beam quality as RSRP as an example, 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.
[0117] Finally, the terminal device can, based on the priority rule, report the beam report associated with the third event. Since the third event is 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 mean value of the quality of the m third beams in the cell. Taking the beam quality as RSRP as an example, the mean value of the RSRP of the m third beams in secondary cell A is -50 dBm, the mean value of the RSRP of the m third beams in secondary cell B is -44 dBm, and the mean value of the RSRP of the m third beams in secondary cell C is -30 dBm. Then, 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.
[0118] This embodiment considers improving communication performance and sets corresponding priorities. The greater the degree of influence of the event type on improving communication performance, the higher its corresponding priority. Among them, the degree of influence on improving communication performance from large to small is the second event, the first event, and the third event. Correspondingly, the priorities from high to low are the second event, the first event, and the third event.
[0119] Optionally, this solution is also applicable to scenarios where communication is based on coordinated multi-point (CoMP) technology. The CoMP technology optimizes the signal quality and data transmission efficiency of terminal devices by coordinating the transmission and reception of data at multiple transmission / reception points (TRPs). In some embodiments, multiple TRPs can be within the coverage of the same base station or the same logical cell. For example, multiple TRPs are within the coverage area managed by the same base station (gNB) or logical cell. They usually share the same physical cell identifier, or are configured as different entities under the same control gNB. In other embodiments, multiple TRPs can be within the coverage of different base stations or different logical cells.
[0120] In the CoMP scenario, as Figure 3 shown, the UE can communicate with TRP1 and TRP2 simultaneously. There is no primary or secondary distinction among multiple TRPs. The terminal device can perform beam measurements on each of the multiple TRPs separately to determine whether to trigger the first event, the second event, or the third event. After the terminal device detects that an event is triggered, it can report the beam report associated with multiple events according to the priority rules described above. For example, in the case where multiple types of events are triggered in one TRP, the beam report associated with the second event is reported first, followed by the beam report associated with the first event, and finally the beam report associated with the third event. Another example is that in the case where multiple types of events are triggered in multiple TRPs, the corresponding beam report is reported according to the priority rules shown in Embodiment 1. For example, 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. In the case where multiple triggered events include multiple first events, the worse the quality of the first beam, the higher the priority of the corresponding first event. In the case where 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 where multiple triggered events include multiple third events, the better the quality of the m third beams, the higher the priority of the third event.
[0121] Embodiment 2: The priority rule is related to the type of the triggered event and the type of the cell corresponding to the triggered event.
[0122] The priority rules are as follows: 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. For the same type of event triggered in both the primary cell and the secondary cell, the priority of the event triggered in the primary cell is higher than that of the event triggered in the secondary cell.
[0123] Table 3
[0124] Specifically, as shown in Table 3, the priority of the second event triggered in the primary cell is higher than that of the second event triggered in the secondary cell; the priority of the second event triggered in the secondary cell is higher than that of the first event triggered in the primary cell; the priority of the first event triggered in the primary cell is higher than that of the first event triggered in the secondary cell; the priority of the first event triggered in the secondary cell is higher than that of the third event triggered in the primary cell; the priority of the third event triggered in the primary cell is higher than that of the third event triggered in the secondary cell.
[0125] In some embodiments, when the same type of event is triggered in multiple secondary cells, the terminal device reports multiple beam reports associated with multiple events of the same type to the network device in a random order. For example, when the second event is triggered in multiple secondary cells, the terminal device may report multiple beam reports associated with the second event triggered in the multiple secondary cells in a random order.
[0126] Exemplarily, taking the cells providing services to the terminal device including a primary cell, secondary cell A, secondary cell B, and secondary cell C as an example. The terminal device detects that the first event and the second event are triggered in the primary cell, the second event and the third event are triggered in secondary cell A, the first event and the third event are triggered in secondary cell B, and the first event, the second event, and the third event are triggered in secondary cell C.
[0127] Based on the priority rule, the terminal device preferentially reports the beam report associated with the second event. Since the second event is 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 cell A and secondary cell C in a random order. Then, the terminal device reports the beam report associated with the first event based on the priority rule. Since the first event is triggered in both the primary cell and multiple secondary cells, the terminal device can 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 events triggered in secondary cell B and secondary cell C in a random order. Finally, the terminal device reports the beam report associated with the third event according to the priority rule. Since the third event is triggered in multiple secondary cells, the terminal device can report the beam reports associated with the third events triggered in secondary cell A, secondary cell B, and secondary cell C in a random order.
[0128] In some embodiments, when the same type of event is triggered in multiple secondary cells, the terminal device reports multiple beam reports associated with multiple events of the same type to the network device in a preset order.
[0129] Exemplarily, when the first event is triggered in multiple secondary cells, the worse the quality of the first beam, the higher the priority of the corresponding first event, that is, the beam report associated with this event is preferentially reported. In other words, when the first event is triggered in multiple secondary cells, the terminal device reports the multiple beam reports associated with the first events triggered in the multiple secondary cells in ascending order of the quality of the first beam.
[0130] Also exemplarily, when the 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, that is, the beam report associated with this event is preferentially reported. In other words, when the second event is triggered in multiple secondary cells, the terminal device reports the beam reports associated with the second events triggered in the corresponding secondary cells in descending order of the average quality of the n second beams in the secondary cells.
[0131] Also exemplarily, when the 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, that is, the beam report associated with this event is preferentially reported. In other words, when the third event is triggered in multiple secondary cells, the terminal device reports the beam reports associated with the third events triggered in the corresponding secondary cells in descending order of the average quality of the m third beams in the secondary cells.
[0132] For example, when the first event, the second event, and the third event are triggered in multiple secondary cells, the priority rules are shown in Table 4. Specifically, the priority of the second event triggered in the primary cell is higher than that of the multiple second events triggered in the secondary cells and sorted in descending order according to the average value of the quality of n second beams; the priority of the multiple second events triggered in the secondary cells and sorted in descending order according to the average value of the quality of n second beams is higher than the priority of the first event triggered in the primary cell; the priority of the first event triggered in the primary cell is higher than the priority of the multiple first events triggered in the secondary cells and sorted in ascending order according to the quality of the first beam; the priority of the multiple first events triggered in the secondary cells and sorted in ascending order according to the quality of the first beam 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 multiple third events triggered in the secondary cells and sorted in descending order according to the average value of the quality of m third beams.
[0133] Table 4
[0134] Continuing with the example in 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.
[0135] When reporting multiple 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 preferentially report 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.
[0136] When reporting multiple 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.
[0137] This embodiment takes into account the requirement of improving communication performance. The greater the impact of the event type on improving communication performance, the higher its corresponding priority. At the same time, considering the transmission requirement of control signaling, for the same type of event triggered in both the primary cell and the secondary cell, the priority of the event triggered in the primary cell is higher than that of the event triggered in the secondary cell.
[0138] In some embodiments, since the secondary cell carries the transmission of service data, considering the transmission requirement of service data, for the same type of event, the event triggered in the secondary cell is more critical. Therefore, for the same type of event, the priority of the event triggered in the secondary cell is higher than that of the event triggered in the primary cell.
[0139] Exemplarily, the priority rule can be: 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. For the same type of event triggered in both the primary cell and the secondary cell, the priority of the event triggered in the secondary cell is higher than that of 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 same type of event as the first event as an example, for the first event triggered in both the primary cell and the secondary cell, the priority of the first event triggered in the secondary cell is higher than that of the first event triggered in the primary cell.
[0140] Another exemplarily, since the secondary cell carries the transmission of service data, for the second event triggered in both the primary cell and the secondary cell, preferentially processing the second event triggered in the secondary cell can most directly improve the data transmission performance and user experience. Therefore, the priority rule can be: 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. For the first event triggered in both the primary cell and the secondary cell, the priority of the first event triggered in the primary cell is higher than that of the first event triggered in the secondary cell. For the second event triggered in both the primary cell and the secondary cell, the priority of the second event triggered in the secondary cell is higher than that of the second event triggered in the primary cell. For the third event triggered in both the primary cell and the secondary cell, the priority of the third event triggered in the primary cell is higher than that of the third event triggered in the secondary cell.
[0141] Embodiment 3: When a cell, such as a primary cell or a secondary cell, triggers a first event indicating that the quality of the first beam of the cell deteriorates, in order to avoid connection interruption caused by continuous deterioration of the quality of the first beam of the cell. In the case where multiple events are triggered, the first event has the highest priority, so that the process of the alternative beam can be triggered as soon as possible to avoid continuous deterioration of the quality of the first beam of the cell that triggers the first event. Therefore, the priority rule is shown in Table 5, where the priority of the first event is higher than that of the second event, and the priority of the second event is higher than that of the third event.
[0142] Table 5
[0143] This embodiment only considers the event type and does not distinguish the cell type. Among them, the first event, the second event, and the third event can all be triggered in the primary cell and / or the secondary cell.
[0144] Optionally, in the case where 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 introduction in Embodiment 1, and details are not described here.
[0145] In some embodiments, considering the transmission requirements of control signaling, the priority of the event triggered in the primary cell is higher than that of the event triggered in the secondary cell. Therefore, the priority rule can be: the priority of the first event is higher than that of the second event, and the priority of the second event is higher than that of the third event. For the same type of event triggered in both the primary cell and the secondary cell, the priority of the event triggered in the primary cell is higher than that of 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 same type of event as the first event, for the first event triggered in both the primary cell and the secondary cell, the priority of the first event triggered in the primary cell is higher than that of the first event triggered in the secondary cell.
[0146] In other embodiments, considering the transmission requirements of service data, the priority of the event triggered in the secondary cell is higher than that of the event triggered in the primary cell. Therefore, the priority rule can be: the priority of the first event is higher than that of the second event, and the priority of the second event is higher than that of the third event. For the same type of event triggered in both the primary cell and the secondary cell, the priority of the event triggered in the secondary cell is higher than that of 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 same type of event as the first event, for the first event triggered in both the primary cell and the secondary cell, the priority of the first event triggered in the secondary cell is higher than that of the first event triggered in the primary cell.
[0147] In some other embodiments, considering the transmission requirements of control signaling and service data comprehensively, the priority of the second event triggered in the secondary cell is higher than that of the second event triggered in the primary cell. Since the secondary cell bears the transmission of service data, in this way, the service transmission performance can be improved as much as possible. For the first event and the third event, the priority of the event triggered in the primary cell is higher than that of the event triggered in the secondary cell. Therefore, the priority rule can be: the priority of the first event is higher than that of the second event, and the priority of the second event is higher than that of the third event. For the first event or the third event triggered in both the primary cell and the secondary cell, the priority of the event triggered in the primary cell is higher than that of the event triggered in the secondary cell. For the second event triggered in both the primary cell and the secondary cell, the priority of the event triggered in the secondary cell is higher than that of the event triggered in the primary cell. This embodiment comprehensively considers the transmission requirements of control signaling and service data. For the first event to ensure connection stability, the event in the primary cell is preferentially processed; for the second event to improve data transmission performance, the event in the secondary cell is preferentially processed, achieving a balance between connection transmission requirements and transmission performance.
[0148] Optionally, when the same type of event is triggered in multiple secondary cells, the terminal device reports multiple beam reports associated with multiple events of the same type to the network device in a preset order. Refer to the introduction in Embodiment 2, which will not be elaborated here.
[0149] Embodiment 4: The priority rule is related to the type of the cell corresponding to the triggered event.
[0150] The priority rule is: the priority of the event triggered in the primary cell is higher than that of the event triggered in the secondary cell, as shown in Table 6.
[0151] Table 6
[0152] The event triggered in the primary cell can be at least one of the first event triggered in the primary cell, the second event triggered in the primary cell, and the third event triggered in the primary cell. The event triggered in the secondary cell can be at least one of the first event triggered in the secondary cell, the second event triggered in the secondary cell, and the third event triggered in the secondary cell. That is to say, any type of event triggered in the primary cell is preferentially reported, and then any type of event triggered in the secondary cell is reported.
[0153] Exemplarily, taking the cells that provide services to a terminal device including a primary cell, secondary cell A, secondary cell B, and secondary cell C as an example. 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.
[0154] The terminal device may preferentially report the beam reports associated with the first event triggered in the primary cell and the beam reports associated with the second event triggered in the primary cell. When the terminal device reports these two beam reports, it may report them in a random order. Then, the terminal device may report the beam reports associated with the events triggered in the secondary cells in a random order.
[0155] In this embodiment, since the primary cell bears the transmission of the control signaling of all cells, considering the transmission requirements of the control signaling, the priority of the events triggered in the primary cell is higher than the priority of the events triggered in the secondary cells.
[0156] Embodiment 5: The priority rule is related to the type of the triggered event and the type of the cell corresponding to the triggered event.
[0157] The priority rule is: the priority of the events triggered in the primary cell is higher than the priority of the events triggered in the secondary cells; for different types of events triggered in the same type of cell, 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.
[0158] Specifically, as shown in Table 7, the priority of the second event triggered in the primary cell is higher than the priority of the first event triggered in the primary cell; the priority of the first event triggered in the primary 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 second event triggered in the secondary cell; the priority of the second event triggered in the secondary cell is higher than the priority of the first event triggered in the secondary cell; the priority of the first event triggered in the secondary cell is higher than the priority of the third event triggered in the secondary cell.
[0159] Table 7
[0160] In some embodiments, in the case where the same type of events are triggered in multiple secondary cells, the terminal device reports multiple beam reports associated with multiple events of the same type to the network device in a random order. Please refer to the description in Embodiment 2, which will not be elaborated here.
[0161] In some embodiments, when the same type of event is triggered in multiple secondary cells, the terminal device reports multiple beam reports associated with multiple events of the same type to the network device in a preset order. Among them, the preset order can 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. Among them, the higher the priority of the event indicates that the beam report associated with the event is reported more preferentially. For specific details, please refer to the description in Embodiment 2, which will not be elaborated here.
[0162] Exemplarily, when the first event, the second event, or the third event is triggered in multiple secondary cells, the priority rules are shown in Table 8. Specifically, the priority of the second event triggered in the primary cell is higher than the priority of the first event triggered in the primary cell; the priority of the first event triggered in the primary 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 multiple second events triggered in the secondary cell and sorted in descending order according to the average value of the quality of the n second beams; the priority of the multiple second events triggered in the secondary cell and sorted in descending order according to the average value of the quality of the n second beams is higher than the priority of the multiple first events triggered in the secondary cell and sorted in ascending order according to the quality of the first beam; the priority of the multiple first events triggered in the secondary cell and sorted in ascending order according to the quality of the first beam is higher than the priority of the multiple third events triggered in the secondary cell and sorted in descending order according to the average value of the quality of the m third beams. It should be understood that the larger the average value of the quality of the n second beams, the better the quality of the n second beams. The larger the average value of the quality of the m third beams, the better the quality of the m third beams.
[0163] Table 8
[0164] Exemplarily, taking the cells providing services for the terminal device including a primary cell, secondary cell A, secondary cell B, and secondary cell C as an example, the terminal device detects that the first event and the second event are triggered in the primary cell, the second event and the third event are triggered in secondary cell A, the first event and the third event are triggered in secondary cell B, and the first event, the second event, and the third event are triggered in secondary cell C.
[0165] The terminal device can, based on the priority rules, preferentially report the beam reports associated with the events triggered in the primary cell. Since the first event and the second event are triggered in the primary cell, then, the terminal device can preferentially report 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.
[0166] Next, the terminal device reports beam reports associated with events triggered in the secondary cell based on the priority rule. Since the first event, the second event, and the third event are triggered in the secondary cell, the terminal device can preferentially report 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.
[0167] For example, the terminal device can sequentially report the beam report associated with the second event triggered in secondary cell A, the beam report associated with the second event triggered in secondary cell C, the beam report associated with the first event triggered in secondary cell C, the beam report associated with the first event triggered in secondary cell B, 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 accordance with the priority rule and the preset order.
[0168] In this embodiment, considering the transmission requirement of the control signaling, the priority of the event triggered in the primary cell is higher than the priority of the event triggered in the secondary cell. At the same time, considering the requirement of improving the communication performance of the primary cell and the secondary cell, when multiple types of events are triggered in the same type of cell, the priorities from high to low are: the second event, the first event, and the third event.
[0169] In some embodiments, considering the transmission requirement of the service data, the first event is triggered in the secondary cell, indicating that the quality of the current beam of the secondary cell deteriorates. To avoid the continuous deterioration of the quality of the current beam and cause connection interruption. For the events triggered in the secondary cell, the first event has the highest priority. Therefore, the priority rule is: the priority of the event triggered in the primary cell is higher than the priority of the event triggered in the secondary cell. For the first event, the second event, and the third event triggered in the primary cell, 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 the first event, the second event, and the third event triggered in the secondary cell, 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. In this embodiment, considering the transmission requirement of the control signaling, the priority of the event triggered in the primary cell is higher than the priority of the event triggered in the secondary cell. At the same time, considering the requirement of improving the communication performance of the primary cell, when multiple types of events are triggered in the primary cell, the priorities from high to low are: the second event, the first event, and the third event. And considering the transmission requirement of the service data, when multiple types of events are triggered in the secondary cell, the priorities from high to low are: the first event, the second event, and the third event.
[0170] Embodiment Six: The priority rules are related to the type of the triggered event and the type of the cell corresponding to the triggered event.
[0171] The priority rules are as follows: The priorities of the first event and the second event triggered in the primary cell are higher than the priorities of the first event and the second event triggered in the secondary cell. The priorities of the first event and the second event triggered in the secondary cell are 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 event and the second event triggered in the same type of cell, the priority of the second event is higher than the priority of the first event.
[0172] Table 9
[0173] Exemplarily, as shown in Table 9, the priority of the second event triggered in the primary cell is higher than the priority of the first event triggered in the primary cell; the priority of the first event triggered in the primary cell is higher than the priority of the second event triggered in the secondary cell; the priority of the second event triggered in the secondary cell is higher than the priority of the first event triggered in the secondary cell; the priority of the first event 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.
[0174] In some embodiments, when the same type of event is triggered in multiple secondary cells, the terminal device reports multiple beam reports associated with multiple events of the same type to the network device in a random order. Please refer to the description in Embodiment Two, which will not be elaborated here.
[0175] In some embodiments, when the same type of event is triggered in multiple secondary cells, the terminal device reports multiple beam reports associated with multiple events of the same type to the network device in a preset order. Among them, the preset order can 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. Among them, the higher the priority of the event indicates that the beam report associated with the event is reported more preferentially. Please refer to the description in Embodiment Two for details, which will not be elaborated here.
[0176] Exemplarily, when the first event, the second event, and the third event are triggered in multiple secondary cells, the priority rules are shown in Table 10. Specifically, the priority of the second event triggered in the primary cell is higher than the priority of the first event triggered in the primary cell; the priority of the first event triggered in the primary cell is higher than the priority of the multiple second events triggered in the secondary cell and sorted in descending order according to the average value of the quality of n second beams; the priority of the multiple second events triggered in the secondary cell and sorted in descending order according to the average value of the quality of n second beams is higher than the priority of the multiple first events triggered in the secondary cell and sorted in ascending order according to the quality of the first beam; the priority of the multiple first events triggered in the secondary cell and sorted in ascending order according to the quality of the first beam 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 multiple third events triggered in the secondary cell and sorted in descending order according to the average value of the quality of m third beams. It should be understood that the larger the average value of the quality of n second beams, the better the quality of n second beams. The larger the average value of the quality of m third beams, the better the quality of m third beams.
[0177] Table 10
[0178] Exemplarily, taking the cells providing services for the terminal device including the primary cell, secondary cell A, secondary cell B, and secondary cell C as an example, the terminal device detects that the first event and the second event are triggered in the primary cell, the second event and the third event are triggered in secondary cell A, the first event and the third event are triggered in secondary cell B, and the first event, the second event, and the third event are triggered in secondary cell C.
[0179] According to the priority rules, the terminal device preferentially reports the beam report associated with the first event triggered in the primary cell and the beam report associated with the second event triggered in the primary cell. When reporting these two beam reports, since the priority of the second event is higher than the priority of the first event in the same type of cell, the terminal device can preferentially report 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.
[0180] Next, according to the priority rules, 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. Since the priority of the second event is higher than the priority of the first event in the same type of cell, the terminal device can preferentially report 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.
[0181] For example, the terminal device may report beam reports associated with the second event triggered in secondary cell A, the beam report associated with the second event triggered in secondary cell C, the beam report associated with the first event triggered in secondary cell C, and the beam report associated with the first event triggered in secondary cell B in sequence according to the priority rule and the preset order.
[0182] Finally, since the third event is not triggered in the primary cell, the terminal device may report the third event associated with the third event triggered in the secondary cell according to the priority rule. For example, the terminal device may report beam reports 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 sequence according to the preset order.
[0183] Compared with Embodiment 4, in this embodiment, the priorities of the third event triggered in the primary cell and the third event triggered in the secondary cell are adjusted backward. The key events triggered in the primary cell, such as the first event and the second event, are reported first, and then the key events triggered in the secondary cell, such as the first event and the second event, are reported.
[0184] In some embodiments, considering the transmission requirements of service data, the first event is triggered in the secondary cell, indicating that the quality of the current beam of the secondary cell deteriorates. To avoid the continuous deterioration of the quality of the current beam and cause connection interruption. For the first event and the second event triggered in the secondary cell, the first event has the highest priority. Therefore, the priority rule may be: the priorities of the first event and the second event triggered in the primary cell are higher than the priorities of the first event and the second event triggered in the secondary cell, the priorities of the first event and the second event triggered in the secondary cell are 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 event and the second event triggered in the primary cell, the priority of the second event is higher than the priority of the first event; for the first event and the second event triggered in the secondary cell, the priority of the first event is higher than the priority of the second event.
[0185] It can be seen that in the embodiments of the present application, when the terminal device detects that multiple events are triggered, it can report beam reports associated with the multiple events to the network device according to the priority rule. It can avoid the uplink resource competition and signaling conflict caused by reporting beam reports associated with multiple events at the same time, and can also avoid the impact on data transmission caused by reporting in a random order.
[0186] In the implementation of the present application, the terminal device reporting the beam report can be understood as the terminal device reporting the beam report to the network device. Among them, reporting can be understood as sending.
[0187] In some embodiments, the terminal device may report beam reports associated with events to the network device via a physical uplink control channel (PUCCH) and a physical uplink shared channel (PUSCH).
[0188] In other embodiments, the terminal device may report beam reports associated with events to the network device only via the PUCCH.
[0189] Taking the terminal device UE and the network device being a gNB as an example, as Figure 4 shown, the UE detects multiple events, and the UE sorts the multiple events according to a priority rule. Among them, the priority rule can be any one shown in Tables 1 - 9. Then, the UE sequentially reports beam reports associated with the events to the gNB according to the sorting result. For example, the UE sends a beam report associated with the highest priority event to the gNB via the PUCCH. Then, the UE sends a beam report associated with the second highest priority event to the gNB via the PUCCH,..., and the UE sends a beam report for reporting a beam report associated with the lowest priority event to the gNB via the PUCCH. Optionally, the UE sends the above beam reports to the gNB via the PUCCH and the PUSCH.
[0190] It can be seen that through comprehensive consideration of factors such as cell type, event type, and beam quality, this application sorts the priorities of multiple events in a conflict scenario. Ensure that high - priority events, that is, key events, can be reported and processed first, and low - priority events are reported later, thereby ensuring the efficiency of beam switching and avoiding unnecessary signaling overhead and saving signaling resources.
[0191] It should be understood that Figures 1 to 4 the flowchart or scenario diagram shown is only for easy understanding and does not intend to limit the embodiments of this application to the examples in the diagram. In fact, those skilled in the art can perform equivalent transformations based on Figures 1 to 4 the examples in it to obtain more implementation manners.
[0192] As described above in combination with Figures 1 to 4 , a method for reporting beam reports provided by the embodiments of this application has been described in detail. Next, the apparatus embodiments of this application will be described in detail in combination with Figure 5 and Figure 6 It should be understood that the communication apparatus in the embodiments of this application can execute various methods for reporting a beam report in the foregoing embodiments of this application. That is, the specific working processes of the following various products can refer to the corresponding processes in the foregoing method embodiments.
[0193] In the foregoing embodiments, the terminal device may execute some or all of the steps in the embodiments; the network device may execute some or all of the steps in the embodiments. These steps or operations are merely examples, and the embodiments of the present application may also execute other operations or various deformations of the operations. In addition, the various steps may be executed in different orders presented in the embodiments, and it is possible that not all of the operations in the embodiments of the present application need to be executed. Moreover, the magnitudes of the sequence numbers of the various steps do not mean the order of execution, and the order of execution of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present application.

Please refer to Figure 5 , Figure 5 which is a schematic structural diagram of a communication device provided by an embodiment of the present application.
