Description

TECHNICAL FIELD

[0001] The present application relates to the field of communication, and in particular to a communication method and related apparatus. BACKGROUND

[0002] Wireless communication can be transmission communication between two or more communication nodes without propagation through a conductor or cable or propagation through an air interface. For example, the communication nodes include network devices and terminal devices. Generally, a terminal device can access a network device and receive scheduling and indication information of the network device to implement wireless communication.

[0003] Currently, a network device configures a resource of a beam for a terminal device, and the terminal device performs beam measurement using the resource and reports a beam report of the beam.

[0004] However, in the current beam measurement scenario, the behavior of the terminal device is controlled by the network device, and the measurement period of the beam is relatively long, which leads to the network device being unable to discover changes in beam quality in a timely manner. SUMMARY

[0005] Embodiments of the present application provide a communication method, in which a terminal device reports first indication information to a network device through a first channel and reports a beam report through a second channel. The beam report includes a measurement value of a reference signal and a configuration of the reference signal, and the reference signal is related to an event. In this way, the network device can timely perceive changes on the terminal side, and the network device can also complete detection and identification of beam report signaling with lower processing complexity through the first indication information.

[0006] A first aspect of the present application provides a communication method, which is executed by a terminal device, or executed by part of components (such as a processor, a chip or a chip system, etc.) in the terminal device, or can also be implemented by a logic module or software that can realize all or part of the functions of the terminal device. In the first aspect and its possible implementation manners, the method is taken as an example executed by the terminal device. In the method, the terminal device sends first indication information to a network device through a first channel, and the first indication information is used to indicate at least one parameter information, and the at least one parameter information at least includes an identifier of an event. The terminal device sends a beam report to the network device through a second channel, and the beam report includes a measurement value of a reference signal and a configuration of the reference signal, and the reference signal is related to the event.

[0007] Based on the above scheme, the terminal device reports first indication information to the network device through a first channel and reports a beam report through a second channel. The beam report includes the measured value and configuration of the reference signal, which is event-related. This approach not only enables the network device to promptly perceive changes on the terminal side through beam reports but also allows the network device to detect and identify beam report signaling with lower processing complexity using the first indication information.

[0008] Optionally, in one possible implementation of the first aspect, the scheduling mode supported by the terminal device is dynamic scheduling, and the first indication information is further used to request the resources used for the beam report; the terminal device is further used to receive the second indication information, which is used to indicate the resources used for the beam report; the terminal device sends the beam report to the network device through the second channel, including: the terminal device is specifically used to send the beam report to the network device through the second channel on the resources.

[0009] In this possible implementation, the terminal device requests the resources used for beam reporting through the first indication information, thereby enabling the network device to clearly indicate the resources that the terminal device needs to use for reporting beam reports, thus achieving dynamic scheduling of beam reports.

[0010] A second aspect of this application provides a communication method, which is executed by a network device, or by a component (e.g., a processor, chip, or chip system) within the network device, or by a logic module or software capable of implementing all or part of the functions of the network device. In this second aspect and its possible implementations, the method is described as being executed by a network device. In this method, the network device receives first indication information sent by a terminal device via a first channel. The first indication information indicates at least one parameter, which includes at least an event identifier. The network device receives a beam report sent by the terminal device via a second channel. The beam report includes measured values ​​of a reference signal and the configuration of the reference signal, which is correlated with the event.

[0011] Based on the above scheme, the network device receives the first indication information reported by the terminal device through the first channel and receives the beam report through the second channel. The beam report includes the measured value of the reference signal and the configuration of the reference signal, which is event-related. Therefore, the network device can not only promptly perceive changes on the terminal side through the beam report, but also complete the detection and identification of beam report signaling with lower processing complexity using the first indication information.

[0012] Optionally, in one possible implementation of the second aspect, the scheduling mode supported by the aforementioned terminal device is dynamic scheduling, and the first indication information is further used to request resources used for beam reporting. The method further includes: the network device sending second indication information to the terminal device, the second indication information being used to indicate the resources used for beam reporting.

[0013] In this possible implementation, the network device uses the first instruction information to clearly indicate the resources that the terminal device needs to use for reporting beam reports, thereby enabling dynamic scheduling of beam reports.

[0014] Optionally, in one possible implementation of the second aspect, the network device determines the scheduling mode supported by the terminal device based on the first indication information or beam report. For example, the network device can determine the scheduling mode supported by the terminal device through the period or time offset of the first indication information. As another example, the network device can determine the scheduling mode supported by the terminal device through the period or time offset of the beam report.

[0015] In this possible implementation, the network device can clearly identify the scheduling mode supported by the terminal device through the first indication information or beam report, reducing the overhead of introducing additional indication bits to indicate the scheduling mode.

[0016] Optionally, in one possible implementation of the first or second aspect, the scheduling mode supported by the aforementioned terminal device is dynamic scheduling, and the first indication information is also used to request the resources used for beam reporting.

[0017] In this possible implementation, the network device can determine the resources that the terminal device uses to report beam reports through the first indication information, thereby enabling dynamic scheduling of beam reports.

[0018] Optionally, in one possible implementation of the first or second aspect, the scheduling mode supported by the aforementioned terminal device is pre-configured scheduling, and the first indication information is also used to notify the network device to receive beam reports on the pre-configured resources.

[0019] In this possible implementation, the network device can determine to receive beam reports on pre-configured resources through the first indication information, without needing to indicate the resources for beam reports through downlink control information, thereby reducing the overhead of additional downlink control information while ensuring correct reception of beam reports.

[0020] Optionally, in one possible implementation of the first or second aspect, the scheduling mode supported by the terminal device is dynamic scheduling, the first indication information is further used to request the resources used for the beam report, and the second indication information is used to confirm the resources used for the beam report requested by the first indication information, or to issue the resources used for the beam report.

[0021] In this possible implementation, after receiving the first instruction information, the network device can also confirm the resources requested by the terminal device or the resources used for beam reports by issuing the second instruction information, thereby enabling dynamic scheduling of beam reports.

[0022] Optionally, in one possible implementation of the first or second aspect, the scheduling mode supported by the aforementioned terminal device is dynamic scheduling and / or pre-configured scheduling, and the period or time domain offset of the first indication information corresponding to different scheduling modes is different, or the period or time domain offset of the beam report corresponding to different scheduling modes is different.

[0023] In this possible implementation, after receiving the first indication information / beam report, the network device can determine the scheduling mode supported by the terminal device through the period or time domain offset of the first indication information / beam report, thereby reducing the bit overhead required for the first indication information to indicate the scheduling mode.

[0024] Optionally, in one possible implementation of the first aspect or the second aspect, the aforementioned first indication information includes a first part and a second part, wherein the first part is used to indicate the scheduling mode supported by the terminal device, and the first part is also used to determine the second part.

[0025] In this possible implementation, the network device can first parse the first part, which can not only determine the scheduling mode supported by the terminal device, but also determine the second part.

[0026] Optionally, in one possible implementation of the first or second aspect, the first part described above is specifically used to determine at least one of the following: determining the parameter information indicated by the second part, and the cyclic redundancy check (CRC) used by the second part.

[0028] Optionally, in one possible implementation of the first or second aspect, the beam reporting described above further includes at least one of the following: identification of the reference signal and the number of reference signals.

[0029] In this possible implementation, after receiving the first indication information and the beam report, the network device can determine which reference signals in the beam report correspond to which event by ascertaining the correlation between the event indicated by the first indication information and the reference information in the beam report, thereby clarifying the reference of the content in the beam report.

[0030] Optionally, in one possible implementation of the first or second aspect, the bit length of the first indication information is related to the CRC of the first indication information, and different bit lengths correspond to different CRCs.

[0031] In this possible implementation, after receiving the first indication information, the network device can determine which CRC to use for verification based on the bit length of the first indication information, thereby improving the efficiency of the network device in parsing the first indication information.

[0032] Optionally, in one possible implementation of the first or second aspect, the aforementioned first indication information indicates at least one parameter information via N bits, where N is an integer greater than or equal to 1, or...

[0033] The first indication information indicates at least one parameter information through the orthogonal cover code (OCC) or cyclic shift used by the first indication information.

[0034] In this possible implementation, in addition to indicating parameter information through N bits, the first indication information can also be combined with OCC or cyclic shift to indicate parameter information, thereby improving the diversity of the parameter information indicated by the first indication information.

[0035] Optionally, in one possible implementation of the first or second aspect, the number of the above-mentioned at least one parameter information is multiple, and the multiple parameter information corresponds to different indicator bits, or at least two of the multiple parameter information share the same indicator bit.

[0036] In this possible implementation, each parameter can occupy independent bits or share bits, thereby reducing the overhead of the first indication information.

[0037] Optionally, in one possible implementation of the first or second aspect, the aforementioned parameter information further includes at least one of the following:

[0038] The terminal device supports scheduling modes, including dynamic scheduling and pre-configured scheduling. Dynamic scheduling is related to the second indication information, while pre-configured scheduling is not related to the second indication information.

[0043] In this possible implementation, by reporting parameter information related to beam reports or the second channel, the network device can not only determine whether to issue beam reports and improve blind detection efficiency, but also use the first indication information to enable the network device to complete the detection and identification of beam report signaling with lower processing complexity.

[0044] Optionally, in one possible implementation of the first or second aspect, the number of the at least one parameter information mentioned above is multiple, and at least two of the multiple parameter information jointly indicate the payload size of the beam report.

[0045] In this possible implementation, the payload size of subsequent beam reports can be indicated by at least two parameter information, thereby reducing the complexity of blind detection processing of network devices.

[0046] Optionally, in one possible implementation of the first or second aspect, at least one of the aforementioned parameter information is related to the content of the beam report.

[0047] In this possible implementation, the network device can determine the content related to the beam report by using the parameter information indicated by the first indication information, thereby improving the accuracy of subsequent interpretation of the beam report.

[0048] Optionally, in one possible implementation of the first or second aspect, the different scheduling modes mentioned above correspond to different parameter information, or the different scheduling modes correspond to different beam reports.

[0049] In this possible implementation, different parameter information or first indication information can be associated with different scheduling modes. In this way, the network device can know the content of the parameter information reported by the first indication information through different scheduling modes.

[0050] Optionally, in one possible implementation of the first or second aspect, the different beam reports corresponding to the different scheduling modes mentioned above include at least one of the following: the reference signal identifiers corresponding to the different scheduling modes are different, the number of reference signals corresponding to the different scheduling modes is different, and the configuration of the reference signals corresponding to the different scheduling modes is different.

[0051] In this possible implementation, different scheduling modes correspond to several possible beam reports, so that network devices can determine the corresponding beam report based on the scheduling mode, or determine the corresponding scheduling mode based on the beam report. The overhead of indicating the scheduling mode or beam report can be reduced through the preset correspondence.

[0052] Optionally, in one possible implementation of the first or second aspect, the aforementioned scheduling mode is associated with the second channel carried by the beam report.

[0053] In this possible implementation, the scheduling mode can be associated with the channel carried by the beam report. For example, if dynamic scheduling requires higher reliability, the second channel can be a PUCCH.

[0114] To facilitate understanding of the technical solutions of the embodiments of this application, a brief introduction of the relevant terms in this application is given below.

[0115] 1. Terminal equipment

[0116] The terminal device can be a wireless terminal device capable of receiving network device scheduling and instruction information. The wireless terminal device can be a device that provides voice and / or data connectivity to the user, or a handheld device with wireless connectivity, or other processing device connected to a wireless modem.

[0117] Terminal devices can communicate with one or more core networks or the Internet via a radio access network (RAN). Terminal devices can be mobile terminal devices, such as mobile phones (or "cellular" phones), computers, and data cards. For example, they can be portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile devices that exchange voice and / or data with the RAN. Examples include personal communication service (PCS) phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), tablets, and computers with wireless transceiver capabilities. Wireless terminal equipment can also be referred to as a system, subscriber unit, subscriber station, mobile station, mobile station (MS), remote station, access point (AP), remote terminal, access terminal, user terminal, user agent, subscriber station (SS), customer premises equipment (CPE), terminal, user equipment (UE), mobile terminal (MT), etc. Terminal equipment can also be wearable devices and next-generation communication systems, such as terminal equipment in 5G communication networks and future communication networks, or terminal equipment in future evolved public land mobile networks (PLMNs).

[0118] 2. Network equipment

[0119] Network devices can be devices within a wireless network. For example, a network device can be a radio access network (RAN) node (or device) that connects terminal devices to the wireless network; it can also be called a base station. Currently, some examples of RAN devices include: next-generation Node B (gNodeB), transmission reception point (TRP), evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home-evolved Node B, or home Node B (HNB)), base band unit (BBU), or wireless fidelity (Wi-Fi) access point (AP) in a network architecture. Additionally, in a network structure, network devices can include centralized unit (CU) nodes, distributed unit (DU) nodes, or RAN devices that include both CU and DU nodes.

[0120] Specifically, network devices can send configuration information to terminal devices (e.g., carried in scheduling messages and / or indication messages). The terminal devices then configure their networks based on this information, aligning the network configurations of the network devices and terminal devices. Alternatively, network configurations can be pre-set in both the network devices and the terminal devices to achieve alignment. In essence, "alignment" means that when there are interactive messages between the network devices and terminal devices, their understanding of the carrier frequency for sending and receiving interactive messages, the determination of the interactive message type, the meaning of the fields carried in the interactive messages, or other configurations of the interactive messages is consistent.

[0121] Furthermore, in other possible cases, the network device can be any other device that provides wireless communication functionality to the terminal device. The embodiments of this application do not limit the specific technology or device form used in the network device. For ease of description, the embodiments of this application are not limited.

[0122] Network equipment may also include core network equipment, such as access and mobility management function (AMF), user plane function (UPF), or session management function (SMF).

[0123] In this application embodiment, the device for implementing the function of the network device can be the network device itself, or it can be a device capable of supporting the network device in implementing that function, such as a chip system, which can be installed in the network device. In the technical solutions provided in this application embodiment, the example of a network device being used to implement the function of the network device is used to describe the technical solutions provided in this application embodiment.

[0124] 3. Configuration and Pre-configuration

[0125] This application uses both configuration and pre-configuration. Configuration refers to the network device / server sending configuration information or parameter values ​​to the terminal device via messages or signaling, so that the terminal device can determine communication parameters or resources for transmission based on these values ​​or information. Pre-configuration is similar to configuration; it can be parameter information or values ​​pre-negotiated between the network device / server and the terminal device, parameter information or values ​​specified by standard protocols for use by the base station / network device or terminal device, or parameter information or values ​​pre-stored in the base station / server or terminal device. This application does not limit this.

[0126] Furthermore, these values ​​and parameters can be changed or updated.

[0127] 4. The terms "system" and "network" in the embodiments of this application can be used interchangeably. "At least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent the following situations: A exists alone, B exists alone, and A and B exist simultaneously, where A and B can be singular or plural. The character " / " generally indicates that the related objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, "at least one of A, B and / or C" can represent: A exists alone, B exists alone, C exists alone, A and B exist simultaneously, A and C exist simultaneously, B and C exist simultaneously, and A, B and C exist simultaneously. And, unless otherwise specified, the ordinal numbers such as "first" and "second" mentioned in the embodiments of this application are used to distinguish multiple objects and are not used to limit the order, sequence, priority or importance of multiple objects.

[0128] 5. In the embodiments of this application, "send" and "receive" indicate the direction of signal transmission. For example, "send information to XX" can be understood as the destination of the information being XX, which may include direct transmission via the air interface or indirect transmission via the air interface by other units or modules. "Receive information from YY" can be understood as the source of the information being YY, which may include direct reception from YY via the air interface or indirect reception from YY via the air interface by other units or modules. "Send" can also be understood as the "output" of the chip interface, and "receive" can also be understood as the "input" of the chip interface; furthermore, "send" can also be understood as the baseband part inside the device outputting information to the radio frequency part, and "receive" can also be understood as the radio frequency part inside the device receiving the information output by the baseband part.

[0129] In other words, sending and receiving can occur between devices, such as between network devices and terminal devices, or within a device, such as between components, modules, chips, software modules, or hardware modules within the device via buses, wiring, or interfaces.

[0130] It is understandable that information may undergo necessary processing, such as encoding and modulation, between the source and destination, but the destination can understand the valid information from the source. Similar statements in this application can be interpreted in a similar way and will not be elaborated further.

[0131] In the embodiments of this application, transmission includes sending and / or receiving. That is, transmission can be sending, receiving, or a combination of sending and receiving; no specific limitation is made here.

[0132] Furthermore, "receiving" can also be understood as detection, listening, etc., without being limited here. For example, "receiving DCI" usually refers to "listening to DCI".

[0133] 6. In this application, "for indicating" can include both direct and indirect indication. When describing an indication information as indicating A, it can be understood that the indication information carries A, directly indicates A, or indirectly indicates A.

[0134] In this application, the information indicated by the instruction information is called the information to be instructed. In specific implementation, there are many ways to instruct the information to be instructed. For example, it can be implemented through direct instruction, such as through the information to be instructed itself or its index. It can also be implemented indirectly by instructing other information, where there is a relationship between the other information and the information to be instructed. Alternatively, only a part of the information to be instructed can be indicated, while the other parts are known or pre-agreed upon. For example, the instruction of specific information can be achieved by using a pre-agreed (e.g., protocol-defined) arrangement of various pieces of information, thereby reducing instruction overhead to some extent.

[0135] The information to be indicated can be sent as a whole or divided into multiple sub-information messages, and the sending period and / or timing of these sub-information messages can be the same or different. This application does not limit the specific sending method. The sending period and / or timing of these sub-information messages can be predefined, for example, according to a protocol, or configured by the transmitting device by sending configuration information to the receiving device. This configuration information can include, for example, but not limited to, one or a combination of at least two of RRC signaling, medium access control (MAC) layer signaling, and physical layer signaling. MAC layer signaling includes, for example, MAC CE; physical layer signaling includes, for example, downlink control information (DCI).

[0136] In this application, unless otherwise specified, the same or similar parts between the various embodiments can be referred to each other. In the various embodiments of this application, and in the various implementation methods / methods / implementations within each embodiment, unless otherwise specified or logically conflicting, the terminology and / or descriptions between different embodiments and between the various implementation methods / methods / implementations within each embodiment are consistent and can be mutually referenced. The technical features in different embodiments and the various implementation methods / methods / implementations within each embodiment can be combined according to their inherent logical relationships to form new embodiments, implementation methods, methods, or implementation approaches. The following embodiments of this application do not constitute a limitation on the scope of protection of this application.

[0137] To facilitate understanding of the methods provided in the embodiments of this application, the system architecture of the methods provided in the embodiments of this application will be described below. It is understood that the system architecture described in the embodiments of this application is for the purpose of more clearly illustrating the solutions of the embodiments of this application and does not constitute a limitation on the solutions provided in the embodiments of this application.

[0138] Please see Figure 1A This is a schematic diagram of the architecture of the communication system 1000 used in an embodiment of this application. Figure 1A As shown, the communication system includes a radio access network (RAN) 100 and a core network 200. Optionally, the communication system 1000 may also include an Internet 300. The RAN 100 includes at least one RAN node (e.g., ...). Figure 1A 110a and 110b, collectively referred to as 110, may also include at least one terminal device (such as...). Figure 1A RAN100, denoted as RAN100, comprises RAN nodes 120a-120j, collectively referred to as RAN120. RAN100 may also include other RAN nodes, such as wireless relay equipment and / or wireless backhaul equipment. Figure 1A (Not shown in the image). Terminal device 120 is wirelessly connected to RAN node 110, and RAN node 110 is wirelessly or wired connected to core network 200. The core network equipment in core network 200 and RAN node 110 in RAN 100 can be independent physical devices, or they can be the same physical device integrating the logical functions of core network equipment and RAN nodes. Terminal devices and RAN nodes can be interconnected via wired or wireless means.

[0139] RAN100 can be an evolved universal terrestrial radio access (E-UTRA) system, an NR system, or a future radio access system as defined in 3GPP. RAN100 can also include two or more of the above-mentioned different radio access systems. RAN100 can also be an open RAN (O-RAN).

[0140] RAN nodes, also known as radio access network equipment, RAN entities, or access nodes, are used to help terminal devices access communication systems wirelessly. In one application scenario, an RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next-generation NodeB (gNB) in a 5G mobile communication system, a next-generation base station in a 6G mobile communication system, or a base station in a future mobile communication system. RAN nodes can also be macro base stations (such as...) Figure 1A 110a in the text), can also be a micro base station or an indoor station (such as... Figure 1A 110b in the middle can also be a relay node or a donor node.

[0141] In another application scenario, multiple RAN nodes can collaborate to help terminal devices achieve wireless access, with different RAN nodes implementing different functions of the base station. For example, a RAN node can be a central unit (CU), a distributed unit (DU), or a radio unit (RU). Here, the CU performs the functions of the base station's Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP), and can also perform the functions of the Service Data Adaptation Protocol (SDAP). The DU performs the functions of the base station's Radio Link Control (RANC) and Medium Access Control (MAC) layers, and can also perform some or all of the physical layer functions. For specific descriptions of these protocol layers, refer to the relevant 3GPP technical specifications. The RU can be used to implement radio frequency signal transmission and reception. The CU and DU can be two independent RAN nodes, or they can be integrated into the same RAN node, such as within a baseband unit (BBU). RUs can be included in radio frequency equipment, such as remote radio units (RRUs) or active antenna units (AAUs). CUs can be further divided into two types of RAN nodes: CU-control plane and CU-user plane.

[0142] In different systems, RAN nodes may have different names. For example, in an O-RAN system, a CU can be called an open CU (O-CU), a DU can be called an open DU (O-DU), and an RU can be called an open RU (O-RU). The RAN nodes in the embodiments of this application can be implemented through software modules, hardware modules, or a combination of software and hardware modules. For example, a RAN node can be a server loaded with the corresponding software modules. The embodiments of this application do not limit the specific technology or device form used in the RAN nodes.

[0143] In addition, RAN nodes can also be called network devices, which are devices deployed in a radio access network to provide wireless communication functions for terminal devices. Network devices can include various forms of macro base stations, micro base stations (also known as small stations), relay stations, access points, etc. The name of the network device may differ in systems employing different radio access technologies, such as eNB or eNodeB (Evolutionary NodeB) in Long Term Evolution (LTE). Network devices can also be radio controllers in Cloud Radio Access Network (CRAN) scenarios. Network devices can also be base station equipment in future 5G networks or network devices in future evolved PLMN networks. Network devices can also be wearable devices or vehicle-mounted devices. Network devices can also be Transmission and Reception Points (TRPs). Furthermore, in a network architecture, network devices can include centralized unit (CU) nodes, distributed unit (DU) nodes, or RAN devices including both CU and DU nodes. For ease of description, a base station will be used as an example of a RAN node in the following description.

[0144] A terminal device is a device with wireless transceiver capabilities, capable of sending signals to or receiving signals from a base station. Terminal devices can also be referred to as user equipment (UE), mobile stations, mobile terminal devices, etc. They can be widely used in various scenarios, such as device-to-device (D2D), vehicle-to-everything (V2X) communication, machine-type communication (MTC), the Internet of Things (IoT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grids, smart furniture, smart offices, smart wearables, smart transportation, and smart cities. Terminal devices can be mobile phones, tablets, computers with wireless transceiver capabilities, wearable devices, vehicles, airplanes, ships, robots, robotic arms, smart home devices, etc. The embodiments of this application do not limit the specific technologies or device forms used in the terminal devices.

[0145] Base stations and terminal equipment can be fixed or mobile. They can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; they can also be deployed on water; and they can be deployed on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of the base stations and terminal equipment.

[0146] The roles of base stations and terminal devices can be relative, for example, Figure 1A The helicopter or drone 120i can be configured as a mobile base station. For terminal devices 120j that access the wireless access network 100 via 120i, terminal device 120i is a base station; however, for base station 110a, 120i is a terminal device, meaning that 110a and 120i communicate via a wireless air interface protocol. Of course, 110a and 120i can also communicate via a base station-to-base station interface protocol; in this case, 120i is also a base station relative to 110a. Therefore, both base stations and terminal devices can be collectively referred to as communication equipment. Figure 1A The 110a and 110b in the text can be referred to as communication devices with base station functions. Figure 1A The 120a-120j in the text can be referred to as communication equipment with terminal device functions.

[0147] Communication between base stations and terminal devices, between base stations, and between terminal devices can be conducted using licensed spectrum, unlicensed spectrum, or both simultaneously. Communication can be conducted using spectrum below 6 GHz, spectrum above 6 GHz, or both simultaneously. The embodiments of this application do not limit the spectrum resources used for wireless communication.

[0148] In the embodiments of this application, the functions of the base station can be executed by modules (such as chips) within the base station, or by a control subsystem that includes base station functions. This control subsystem, including base station functions, can be a control center in the aforementioned application scenarios such as smart grids, industrial control, intelligent transportation, and smart cities. Similarly, the functions of the terminal device can be executed by modules (such as chips or modems) within the terminal device, or by a device that includes terminal device functions.

[0149] As can be understood, RAN100, as previously described, includes at least one RAN node (e.g., Figure 1A 110a and 110b, collectively referred to as 110, may also include at least one terminal device (such as...). Figure 1A 120a-120j in the series are collectively referred to as 120).

[0150] In one possible implementation method Figure 1A The communication system shown can also be as follows Figure 1B As shown, it includes one RAN node 110 and multiple terminal devices (such as...). Figure 1B (Referring to 120A and 120B in the original text). In this case, a single RAN node can transmit data or control signaling to one or more terminal devices.

[0151] In another possible way of implementation Figure 1A The communication system shown can also be as follows Figure 1C As shown, this includes multiple RAN nodes (such as...) Figure 1C 110 (110A, 110B, and 110C) 110 and a terminal device 120. In this case, multiple RAN nodes can also transmit data or control signaling to a single terminal device simultaneously.

[0152] During beam management, network devices configure beam resources for terminal devices, which then use these resources to perform beam measurements and report beam data. However, in current beam measurement scenarios, the behavior of terminal devices is controlled by network devices (or, in other words, terminal devices only perform beam measurements and report data based on the network device's configuration or instructions). Furthermore, the beam measurement cycle is relatively long, causing the beam reports received by the network device to fail to promptly describe changes at the terminal side. This means the network device may be unable to detect changes in beam quality at the terminal in a timely manner.

[0153] To address the aforementioned technical problems, embodiments of this application provide a communication method in which a terminal device reports first indication information to a network device via a first channel and reports a beam report of a reference signal via a second channel. The beam report includes the measured value of the reference signal and the configuration of the reference signal, and the reference signal is event-related. This approach not only enables the network device to promptly perceive changes on the terminal side through the beam report but also allows the network device to detect and identify beam report signaling with lower processing complexity using the first indication information.

[0154] Please see Figure 2This application provides a schematic flowchart of a communication method, which may include steps 201 to 203. Steps 201 to 203 may be executed by a communication device (network device and / or terminal device), or by some components of the communication device (e.g., processor, chip, or chip system), or by a logic module or software capable of implementing all or part of the functions of the communication device. The following description uses the execution by a network device and a terminal device as an example. The processing performed by a single execution entity in steps 201 to 203 may also be divided into multiple execution entities, which may be logically and / or physically separated. For example, when the communication device is a network device, the processing performed by the communication device may be divided into execution by at least one of CU, DU, and RU. Steps 201 to 203 will be described in detail below.

[0155] Step 201: The network device sends a reference signal to the terminal device. This step is optional.

[0156] Optionally, the network device sends a reference signal to the terminal device. Correspondingly, the terminal device receives the reference signal sent by the network device.

[0157] The reference signal can be a reference signal with a transmission period or a reference signal without a transmission period, etc., and the specifics are not limited here.

[0158] Optionally, the reference signal corresponds to a specific beam, or it can be understood that the reference signal is used for beam measurement.

[0159] Furthermore, after receiving the reference signal, the terminal device measures the reference signal to obtain corresponding measurement values. These measurement values ​​may include at least one of the following: reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), signal to interference plus noise ratio (SINR), and channel quality indicator (CQI).

[0160] Optionally, after the reference signal satisfies the event triggering condition, subsequent step 202 is executed. Of course, step 202 may not have a causal relationship with step 201; this is not limited here. The event will be described later and will not be elaborated upon here.

[0161] Step 202: The terminal device sends the first indication information through the first channel.

[0162] The terminal device sends first indication information through the first channel. Correspondingly, the network device receives the first indication information through the first channel.

[0163] The first indication information is used to indicate at least one parameter, which includes at least an event identifier. The first channel may include at least one of the following: a Physical Uplink Control Channel (PUCCH) or a Physical Uplink Shared Channel (PUSCH), etc.

[0164] In this embodiment, the event identifier is used to distinguish different events, or to distinguish different types of events. Alternatively, it can be understood that events of the same type can have the same or different identifiers. The following description uses the event identifier to represent the type of event as an example.

[0165] The event type can include at least one of the following: event1, event2, event7a, event7b, etc.

[0166] For example, event 1 refers to a beam quality below a threshold. As another example, event 2 refers to at least one new beam having a quality better than the current beam's quality plus a threshold. As yet another example, event 7a refers to at least one new beam having a quality better than the worst-quality reference signal among the reference signals associated with the activated TCI state plus a threshold. As yet another example, event 7b refers to at least one new beam having a quality better than the best-quality reference signal among the reference signals associated with the activated TCI state plus a threshold. The beam quality can be represented by various measurements from step 201, such as L1-RSRP and L1-SINR, and the specific representation of beam quality is not limited.

[0167] The first indication information in the embodiments of this application may refer to uplink control information (UCI), or it may be a first indication information that includes UCI and other information, etc., and the specifics are not limited here.

[0168] Optionally, to improve the efficiency of network devices in parsing the first indication information, the first indication information includes a first part and a second part. The first part is used to indicate the scheduling mode supported by the terminal device. The first part is also used to determine the second part. The second part includes some or all of the parameter information from at least one parameter information. The at least one parameter information will be described later and will not be elaborated here. Alternatively, it can be understood that the first part of the first indication information is used by the network device to correctly parse the second part or the beam report.

[0169] The first indication information or the first part indicating the scheduling mode can be a direct indication or an indirect indication based on parameters such as the period (examples will be given later. We will not elaborate on it here). No specific limitation is made here.

[0170] Furthermore, the first part / first indication information corresponding to different scheduling modes can be the same or different. That is, the first part / first indication information corresponding to different scheduling modes can be the same or have differences. For example, if the first part corresponding to different scheduling modes is different, the network device can determine which scheduling mode the terminal device supports by the difference in the first part, thereby reducing the indication bits indicating the scheduling mode.

[0171] Optionally, the scheduling mode can also be associated with a second channel carried by subsequent beam reports. For example, if dynamic scheduling requires higher reliability, the second channel can be a PUCCH.

[0172] The term "related" or "associated" in the embodiments of this application can be understood as a preset association or mapping relationship. This could be an association / mapping relationship negotiated in advance between the network device and the terminal device, an association / mapping relationship adopted by the network device or terminal device as specified in a standard protocol, or an association / mapping relationship pre-stored in the network device or terminal device. This application does not limit this.

[0173] For example, the first part is specifically used to determine at least one of the following: the bit length of the second part, the parameter information indicated by the second part, and the cyclic redundancy check (CRC) used in the second part. Alternatively, after receiving the first indication information, the network device can first parse the first part, and then determine at least one of the following in the subsequent second part based on the parsing result of the first part: the bit length of the second part, the CRC used in the second part, and the specific parameter information indicated by the second part, etc., without being limited here.

[0174] The scheduling modes in this application embodiment include dynamic scheduling and pre-configured scheduling. Dynamic scheduling is related to DCI, while pre-configured scheduling is independent of DCI. DCI is used to indicate the resources used for beam reporting. For example, under dynamic scheduling, the first indication information may affect DCI resolution.

[0175] Dynamic scheduling can be understood as a scheduling mode in which network devices need to dynamically configure the resources used by beam reports using DCI. Pre-configured scheduling can be understood as a scheduling mode in which network devices do not need to instruct beam reports to use resources through DCI.

[0176] The scheduling process corresponding to different scheduling modes will be described next. For ease of description, dynamic scheduling refers to mode A, and pre-configured scheduling refers to mode B as examples.

[0177] 1. Mode A includes at least three steps. These are:

[0178] Step 1: The terminal device sends a first PUCCH (one bit / multiple bits) to request resources in the second UL channel to carry a beam report (resources used to request a beam report). FFS: Request format, such as SR or a newer UCI type.

[0179] Step 2: The network device sends a DCI, and the terminal device detects the DCI format to indicate the resources for carrying beam reports on the second UL channel.

[0180] Step 3: The terminal device transmits a beam report in the second UL channel. The second UL channel may include: PUCCH and / or PUSCH.

[0181] 2. Mode B includes two steps:

[0182] Step 1: The terminal device sends a first PUCCH (one bit / multiple bits) to notify the second UL channel to carry the beam report (notifying on which resource the beam report is carried). FFS: Notification format, such as SR or a newer UCI type.

[0183] Step 2: The terminal device sends a beam report in the second UL channel. FFS: Detailed information about the second UL channel, such as whether the second UL channel is PUCCH, PUSCH, or both.

[0184] In one possible implementation, the terminal device supports a dynamic scheduling mode, and the first indication information is also used to request resources for beam reporting. Alternatively, the first indication information can be understood as requesting resources for the second channel.

[0185] In another possible implementation, the terminal device supports dynamic scheduling. The first indication information is also used to request resources for beam reporting, and the second indication information is used to confirm the resources requested by the first indication information, or to issue beam reporting. Accordingly, after receiving the first indication information, the network device can send the second indication information to the terminal device. The second indication information is used to confirm the resources requested by the first indication information, or to issue beam reporting.

[0186] In another possible implementation, the terminal device supports a pre-configured scheduling mode, and the first indication information is also used to inform the network device not to use the resources for issuing beam reports. Alternatively, the first indication information can be understood as notifying the use of pre-configured resources for the second channel.

[0187] It is understandable that terminal devices may support only dynamic scheduling, only pre-configured scheduling, or both. In this case, different scheduling modes may correspond to different resources.

[0188] Optionally, different scheduling modes correspond to different parameter information, or different first indication information, or different beam reports. Thus, after the network device determines the scheduling modes supported by the terminal device, it can determine the corresponding parameter information or first indication information based on the scheduling mode. Alternatively, it can determine the scheduling modes supported by the terminal device based on the parameter information or first indication information.

[0189] For example, the different beam reports corresponding to the different scheduling modes mentioned above include at least one of the following: the reference signal identifiers are different for different scheduling modes, the number of reference signals is different for different scheduling modes, and the configuration of the reference signals is different for different scheduling modes.

[0190] Furthermore, the time-domain period of the first indication information / beam report differs for different scheduling modes. Alternatively, the time-domain offset of the first indication information / beam report differs for different scheduling modes. Or, this could be understood as the aforementioned first indication information or the first part indicating the scheduling mode being an indirect indication.

[0191] The following example uses the time-domain period or time-domain offset of the first indication information, which corresponds to the scheduling mode, as an example. In practical applications, the time-domain period or time-domain offset of beam reporting, etc., can also correspond to the scheduling mode, but this is not limited here.

[0192] For example, such as Figure 3A As shown, if the time domain period of the first indication information is two time slots (i.e., the first indication information is transmitted on time slots 1, 3, 5, and 7, etc.), then the scheduling mode supported by the terminal device is mode A. If the time domain period of the first indication information is five time slots (i.e., the first indication information is transmitted on time slots 0 and 4, etc.), then the scheduling mode supported by the terminal device is mode B. Therefore, the network device can determine the scheduling mode supported or indirectly indicated by the terminal device based on the period of the first indication information.

[0193] For example, if the periods of the first indication information corresponding to different scheduling modes are the same, the scheduling mode supported by the terminal device can be determined based on the different time-domain offsets. Alternatively, it can be understood that different scheduling modes can be distinguished based on the different periods of the first indication information, or based on whether they are offset from the reference period, or based on the different offset values ​​from the reference period.

[0194] For example, such as Figure 3B As shown, the period of the first indication information corresponding to different scheduling modes is two time slots. For example, assuming the reference is 0246, if the first indication information is periodically transmitted on time slots 1, 3, 5, and 7, then the time domain offset of the first indication information is 1, and the scheduling mode supported by the terminal device corresponding to the time domain offset of 1 can be determined to be mode A. If the first indication information is periodically transmitted on time slots 0, 2, 4, and 6, then the time domain offset of the first indication information is 0, and the scheduling mode supported by the terminal device corresponding to the time domain offset of 0 can be determined to be mode B.

[0195] Optionally, at least one parameter is related to the content of the beam report. This allows the network device to understand the content of the beam report after receiving the first indication information, thereby improving the efficiency of the network device in parsing the beam report and reducing the complexity of blind detection.

[0196] In this embodiment of the application, at least one of the following parameter information is included:

[0197] 1. Scheduling modes supported by the terminal device (hereinafter referred to as parameter 1). Scheduling modes include the aforementioned dynamic scheduling and pre-configured scheduling.

[0198] 2. The identifier of the event associated with the scheduling mode (hereinafter referred to as parameter 2). For example, dynamic scheduling is associated with the first event, and pre-configured scheduling is associated with the second event.

[0199] 3. Event-related beam information (hereinafter referred to as parameter 3).

[0200] 4. The payload size or the range to which the payload size belongs, which is related to the beam report (hereinafter referred to as parameter 4).

[0201] 5. The second channel is PUCCH or PUSCH (hereinafter referred to as parameter 5).

[0202] 6. Resources used by the second channel (hereinafter referred to as parameter 6), etc.

[0203] Optionally, different scheduling modes can correspond to different parameter information or first indication information. In this way, after receiving the first indication information, the network device can first determine the scheduling mode supported by the terminal device, and then determine the corresponding parameter information or first indication information based on the scheduling mode. This allows the network device to improve the efficiency of subsequent beam report parsing and reduce blind detection complexity. Alternatively, the network device can first determine the first indication information or the parameter information within it, and then determine the scheduling mode supported by the terminal device based on the first indication information or the parameter information. This allows the network device to determine whether it needs to issue a DCI indication of the resources used for beam reports based on the scheduling mode supported by the terminal device.

[0204] To facilitate understanding, the following examples will illustrate the various parameter information mentioned above, using the first case of the indication method as an example.

[0205] In this application embodiment, the first indication information can indicate at least one parameter information in various ways. For example, the first indication information can indicate at least one parameter information using N bits. Another example is that the first indication information can indicate at least one parameter information using an orthogonal cover code (OCC) or cyclic shift, where N is an integer greater than or equal to 1. The different indication methods will be described below using two cases.

[0206] The first case: The first indication information indicates at least one parameter information through N bits.

[0207] In this case, the first indication information includes N bits, that is, the first indication information may include 1 bit, 2 bits, or more than 2 bits, etc., and the specifics are not limited here.

[0208] In this context, at least one bit corresponds to one or more indicator bits. Alternatively, the first indication information includes at least one indicator bit. Each indicator bit corresponds to at least one bit.

[0209] For example, the first indication information includes 1 bit, and the terminal device has preset resources corresponding to the event identifier. Thus, the type of the event and the corresponding resources for the subsequent second channel can be indicated by indicating 1 bit. For instance, taking the event identifier as the type of the event, a first indication of "0" indicates that the event type is 1, and the event of type 1 is associated with resource 1. As another example, a first indication of "1" indicates that the event type is 2, and the event of type 2 is associated with resource 2. Furthermore, the network device can use this first indication information to clearly determine on which resources the beam report is received and the event type related to the beam information in the beam report.

[0210] Optionally, when there are multiple parameters, the multiple parameters may correspond to different indicator bits (i.e., multiple parameters may be indicated by independent bits), or at least two of the multiple parameters may share the same indicator bit, etc., which is not specifically limited here.

[0211] Optionally, the bit length of the first indication information is related to the CRC used in the first indication information, or the combination method of the parameters in the first indication information is related to the CRC. This can reduce the complexity of blind detection of the first indication information by network devices.

[0212] For example, different bit lengths correspond to different CRCs. Alternatively, different combinations of multiple indicator bits correspond to different CRCs. The combinations of multiple indicator bits will be described in detail later and will not be elaborated on here. This method can reduce the complexity of blind detection in network devices, and can also distinguish first indicator information of different bit lengths, or distinguish combinations of multiple indicator bits, by using different CRCs.

[0213] Let's take the first case as an example to explain the various parameter information mentioned above.

[0214] 1. Explanation of parameter 1.

[0215] Optionally, the terminal device can indicate the scheduling mode supported by the terminal device via parameter 1.

[0216] Furthermore, events are related to the scheduling modes supported by the terminal device. For example, a network device can determine the scheduling modes supported by the terminal device based on the type of event. As another example, a network device can determine the type of event based on the scheduling modes supported by the terminal device.

[0217] For example, if the terminal device supports dynamic scheduling, the first indication information is also used to indicate the resources used by the network device to send the beam report. That is, the network device can also send the resources used for the beam report to the terminal device.

[0218] For example, if the terminal device supports a dynamic scheduling mode, the first indication information is also used to request the resources used for the beam report, and the second indication information is used to confirm the resources used for the beam report requested by the first indication information, or to issue the resources used for the beam report.

[0219] Alternatively, it can be understood that dynamic scheduling is related to the second indication information, while pre-configured scheduling is unrelated to the second indication information. The second indication information is used to confirm the resources used by the beam report requested by the first indication information, or to issue the beam report.

[0220] For example, the scheduling mode supported by the terminal device is pre-configured scheduling, and the first indication information is also used to indicate that the network device does not need to use the resources used to issue beam reports.

[0221] For example, the terminal device supports both dynamic scheduling and pre-configured scheduling. The first indication information is also used to indicate that the terminal device supports both scheduling modes at the same time, and different scheduling modes are associated with their own scheduling processes and resources.

[0222] It is understandable that parameter 1 can be indicated through bitmap or other means, but no specific restrictions are made here.

[0223] For example, parameter 1 corresponds to a first indication bit in the first indication information. The first indication bit includes at least one bit. At least one bit can indicate the corresponding scheduling mode according to a convention.

[0224] For example, the first indicator bit can be 1 bit to describe the scheduling modes supported by the terminal device. For instance, a first indicator bit of "0" indicates that the terminal device supports pre-configured scheduling, and a first indicator bit of "1" indicates that the terminal device supports dynamic scheduling. Of course, it is also possible that a first indicator bit of "0" indicates that the terminal device supports dynamic scheduling, and a first indicator bit of "1" indicates that the terminal device supports pre-configured scheduling.

[0225] For example, the first indicator bit can use 2 bits to describe the scheduling modes supported by the terminal device. For instance, a first indicator bit of "01" indicates that the terminal device supports pre-configured scheduling, a first indicator bit of "10" indicates that the terminal device supports dynamic scheduling, and a first indicator bit of "11" indicates that the terminal device supports both dynamic and pre-configured scheduling. Of course, it is also possible that the first indicator bit of "01" indicates that the terminal device supports dynamic scheduling, and the first indicator bit of "10" indicates that the terminal device supports pre-configured scheduling.

[0226] For example, the first indicator bit can use 2 bits to describe the pre-configured resources used by at least one scheduling mode, and different bits in the first indicator information correspond to different pre-configured resources. That is, the first indicator information can choose one of the multiple pre-configured resources to notify. For example, the first indicator information uses "01" to represent one of the multiple pre-configured resources, and uses "10" to represent another of the multiple pre-configured resources.

[0227] As can be seen, by reporting parameter 1, the network device can determine whether to use mode A or mode B in conjunction with beam reporting. That is, the network device can determine whether it needs to send the DCI in step 2 of mode A based on parameter 1. If the terminal device supports mode B, it can include parameter 1 in the first indication information, thus eliminating the need for the network device to send the DCI and reducing unnecessary DCI overhead. Of course, if the terminal device supports both mode A and mode B, the network device can send a DCI to indicate the resources used for beam reporting corresponding to mode A, but does not need to send a DCI to indicate the resources used for beam reporting corresponding to mode B.

[0228] 2. Explanation of parameter 2.

[0229] Optionally, the terminal device can also indicate the events associated with the scheduling mode via parameter 2. Different events can be distinguished by type or identifier, etc., but this is not specifically limited here.

[0230] Optionally, different scheduling modes can be associated with one or more events. Alternatively, mode A can be associated with one or more events, and mode B can be associated with one or more events.

[0231] For example, dynamic scheduling is associated with a first event, and pre-configured scheduling is associated with a second event. The first event and the second event may be the same or different, and the number of first events and second events may be one or more. Wherein, the first event and the second event being the same can mean that at least one of the following is the same: type, threshold used for the event, etc., which is not limited here.

[0232] For example, mode A is associated with event1, and mode B is associated with event2.

[0233] Optionally, the type of event is related to the bit length of the beam report and / or the content of the beam report (e.g., the beam in the beam report). For example, different types of events correspond to different bit lengths of beam reports. For example, different types of events correspond to different beam report contents.

[0234] For example, parameter 2 corresponds to a second indication bit in the first indication information. The second indication bit includes at least one bit. At least one bit can indicate the corresponding event type by convention.

[0235] As can be seen, by reporting parameter 2, the network device can know the specific event type that triggered the beam report.

[0236] 3. Explanation of parameter 3.

[0237] Optionally, the terminal device can also indicate beam information related to the event via parameter 3. Different events can be distinguished by type or identifier, etc., which is not limited here.

[0238] The beam information includes at least one of the following: the identifier of the beam associated with the event, the number of beams, and the time and frequency resources used by the beams.

[0239] Optionally, dynamic scheduling is associated with a first event, and pre-configured scheduling is associated with a second event. The first indication information can also indicate the number of first beams associated with the first event and / or the time-frequency resources of the first beams via parameter 3. Similarly, parameter 3 can indicate the number of second beams associated with the second event and / or the time-frequency resources of the second beams.

[0240] For example, event type 1 is associated with beam 1 and beam 2. After receiving the first indication information and subsequent beam reports, the network device can determine which event type the measurement value in the beam report corresponds to. Alternatively, subsequent beam reports may not require beam identification. The network device can use the above associations to sequentially determine which beams correspond to which measurement values ​​from the beam reports.

[0241] For example, parameter 3 corresponds to a third indication bit in the first indication information. The third indication bit includes at least one bit. At least one bit can indicate the corresponding number of beams or the corresponding time-frequency resources in a predetermined order.

[0242] For example, the third indicator bit can use 4 bits to describe the number of beams in parameter 3. Assume the maximum number of beams configured in the RRC is 4, and the aforementioned parameters involve event1 + event2. For instance, the third indicator bit can use "0110" to represent the number of beams corresponding to each event, with the first two bits corresponding to one event and the last two bits corresponding to another. event1 corresponds to the first two bits "01", and event2 corresponds to the last two bits "10", meaning event1 is associated with 2 beams, and event2 is associated with 3 beams.

[0243] As can be seen, by reporting parameter 3, the network device can determine the specific event type that triggered the beam report, and which event type the measurement value in the beam report corresponds to, thus clarifying what the measurement value in the beam report refers to. Furthermore, the terminal device can use parameter 3 to indicate to the network device the number of beams associated with the event and / or the time-frequency resources of the beams. This improves the ability of subsequent network devices to accurately determine the time-frequency location of the beams.

[0244] 4. Explanation of parameter 4.

[0245] Optionally, the terminal device can also indicate the range to which the payload size belongs or the size of the payload related to subsequent beam reports via parameter 4.

[0246] It is understandable that parameter 4 can indicate the payload range or the payload size. Specifically, parameter 4 can directly indicate the payload size of the beam report, or it can be combined with other parameters to indicate the payload size of the beam report, etc., which is not limited here.

[0247] In this context, parameter 4, combined with other parameters, indicates the payload size of the beam report. This can mean that parameter 4 in the first indication information indicates a range, and the specific payload size is determined from this range by combining it with other parameters. For example, the other parameters could specifically indicate a value in the RRC configuration. In other words, at least two parameters from multiple parameter information pieces jointly indicate the payload size of the beam report.

[0248] For example, parameter 4 corresponds to the fourth indicator bit in the first indicator information. The fourth indicator bit includes at least one bit. The at least one bit can, by convention, indicate the payload size or the range to which the payload size belongs.

[0249] For example, the fourth indicator bit can be "10000000" to indicate that the payload size is 128 bits. Alternatively, the fourth indicator bit can be "01" to indicate a payload size range of 1 to 128 bits, or "10" to indicate a payload size range of 129 to 256 bits.

[0250] Furthermore, this interval can also be related to the combination method of each indicator bit in the first indication information. For example, interval 1 corresponds to combination method 1, and interval 2 corresponds to combination method 2. And combination method 1 corresponds to a preset parameter, so the related parameters that are the same as the preset parameter can be omitted in the first indication information, and the preset parameter can be directly indicated by combination method 1.

[0251] It can be seen that the terminal device can indicate to the network device the range or size of the payload of the subsequent beam report through parameter 4, thereby reducing the blind detection overhead of the network device.

[0252] 5. Explanation of parameter 5.

[0253] Optionally, since the second channel can be either PUCCH or PUSCH, the terminal device can indicate to the network device via parameter 5 whether the second channel is carried by PUCCH or PUSCH so that the network device can clearly specify which channel to receive subsequent beam reports.

[0254] Optionally, the second channel carried by the beam report can also be associated with other parameters.

[0255] For example, the channel carried by the second channel is associated with the aforementioned scheduling mode. For instance, if dynamic scheduling requires higher reliability, the second channel can be a PUCCH.

[0256] For example, the second channel may be associated with the aforementioned event. For instance, if event2 has a higher priority, then the second channel could be a PUCCH.

[0257] For example, the beam report may carry a second channel associated with a measurement configuration of multiple different component carriers (CC), or the beam report may carry a channel associated with a component carrier configuration associated with the beam report configuration.

[0258] For example, parameter 5 corresponds to the fifth indication bit in the first indication information. The fifth indication bit includes at least one bit. At least one bit can indicate the corresponding channel according to convention.

[0259] For example, the fifth indicator bit can be used to describe whether the second channel is PUCCH or PUSCH using 1 bit. For instance, a fifth indicator bit of "0" indicates that the second channel is carried by PUCCH, and a fifth indicator bit of "1" indicates that the second channel is carried by PUSCH. Of course, it is also possible for the fifth indicator bit to be "0" to indicate that the second channel is carried by PUSCH, and for the fifth indicator bit to be "1" to indicate that the second channel is carried by PUCCH.

[0260] As can be seen, the terminal device can indicate to the network device via parameter 5 whether the subsequent beam report is carried on PUCCH or PUSCH. This improves the network device's ability to know which channel to receive the beam report on.

[0261] 6. Explanation of parameter 6.

[0262] Optionally, the terminal device can also indicate the resources used by the channel carrying the beam report via parameter 6. That is, parameter 6 can indicate the resources of the PUCCH or the resources of the PUSCH.

[0263] The resources can include at least one of the following: time-domain resources, frequency-domain resources, etc. For example, parameter 6 can indicate the starting position and the number of time-domain units used by the PUCCH. As another example, parameter 6 can indicate the starting position and the number of time-domain units used by the PUSCH. For instance, the resources can be the CSI resource configuration used for channel measurement in the channel state information (CSI) resource setting, specifically including time-frequency position, code division multiplexing (CDM) type, power offset, scrambling code, and other configurations.

[0264] The time-domain resources in the embodiments of this application may refer to at least one of the following: resource element (RE), resource block (RB), interlace, subchannel, RB set (RBset), subcarrier, BWP, component carrier, carrier, frequency band, Hertz (Hz), kilohertz (kHz), megahertz (MHz), etc., without being specifically limited here.

[0265] The frequency domain resources in this application embodiment may refer to at least one of the following: wireless frame, subframe, slot, mini slot, orthogonal frequency division multiplexing (OFDM) symbol, second, millisecond, microsecond, etc., without being specifically limited here.

[0266] For example, the channel association carrying the beam report has multiple different component carriers (CCs).

[0267] For example, parameter 6 corresponds to the sixth indicator bit in the first indicator information. The fifth indicator bit includes at least one bit. At least one bit can indicate the corresponding resource according to a convention. For example, it can be indicated by a start position and length.

[0268] It can be seen that the terminal device can indicate the resources used for subsequent beam reports to the network device through parameter 6 in the first indication information, thereby improving the efficiency of the subsequent network device in receiving beam reports.

[0269] The parameters have been explained above. It's understandable that there can be relationships between these parameters. Several examples are given below. Specific relationships are not limited here.

[0270] Example 1: Parameter 1 describes dynamic scheduling, and the event type in parameter 2 is the event type associated with dynamic scheduling. Alternatively, parameter 1 describes pre-configured scheduling, and the event type in parameter 2 is the event type associated with pre-configured scheduling.

[0271] Example 2: Parameter 2 describes event type 1. Parameter 3 describes the beam information related to event type 1.

[0272] Example 3: Different scheduling modes can correspond to different parameter information. For example, if parameter 1 indicates a dynamic scheduling mode, the first indication information may not include events or beam information associated with the pre-configured scheduling mode. As another example, if parameter 1 indicates a pre-configured scheduling mode, the first indication information may not include events or beam information associated with the dynamic scheduling mode.

[0273] Example 4: The payload range indicated by parameter 4 can be related to the combination of each indicator bit in the first indication information. For example, combination mode 1 corresponds to a preset parameter, so the first indication information can omit related parameters that are the same as those indicated by the preset parameter, and directly indicate the corresponding parameters indirectly through combination mode 1.

[0274] Example 5: The effective load range indicated by parameter 4 can be combined with other parameters to further determine the effective load size.

[0275] The second scenario: The first indication information indicates at least one parameter information through transmission parameters such as OCC or cyclic shift used by the first indication information.

[0276] The transmission parameters may include at least one of the following: OCC or cyclic shift, etc., without specific limitations here. Several mapping relationships are described below as examples:

[0277] For example, the aforementioned parameters such as parameter 1 (scheduling mode) and parameter 4 (payload size) are mapped to cyclicshift.

[0278] For example, Table 1 provides an example of a mapping relationship:

[0279] Table 1

[0280] Scheduling mode + payload size A, payload 1 A, payload 2 B, payload 3 B, payload 4 Cyclic shift MCS = 0 MCS = 3 MCS = 6 MCS = 9

[0281] As shown in Table 1, the modulation and coding scheme (MCS) using cyclic shifting indicates the corresponding scheduling mode and payload size. For example, MCS=0 corresponds to scheduling mode A and payload size 1. MCS=3 corresponds to scheduling mode A and payload size 2. MCS=4 corresponds to scheduling mode B and payload size 3. MCS=9 corresponds to scheduling mode B and payload size 4.

[0282] For example, the aforementioned parameters such as parameter 1 (scheduling mode) and parameter 5 (second channel carried by beam reporting) have a mapping relationship with OCC. For instance, the PUCCH carried by the second channel has a mapping relationship with OCC.

[0283] For example, Table 2 provides an example of a mapping relationship:

[0284] Table 2

[0285]

[0286]

[0287] Where N represents the sequence number or the number of frequency hopping within a time slot under the PUCCH 1 format, and the value of i corresponds to "parameter 1 (scheduling mode) and parameter 6 (second channel carried by beam report)". Alternatively, it can be understood that different N and i correspond to different orthogonal sequence values.

[0288] It is understandable that the above mapping relationships are just examples. In practical applications, there may be other mapping relationships, which are not limited here.

[0289] In addition to including at least one of the aforementioned parameter information (hereinafter referred to as UEI), the first indication information may also include at least one of the following: hybrid automatic repeat request (HARQ) acknowledgments (ACK) / negative acknowledgments (NACK), scheduling request (SR), CSI, etc.

[0290] Optionally, the priority order of the above items is: HARQ response > SR > UEI > CSI. For example, if the first indication information cannot be fully carried due to output limitations and some indications need to be discarded, the decision can be made according to the priority order.

[0291] For example, the first indication information includes: HARQ response, SR, UEI, and CSI. When calculating whether to discard CSI, the proportion of bits of UEI is included in the total number of bits of the first indication information, or it can be understood as discarding CSI with lower priority.

[0292] Furthermore, if transmission restrictions necessitate discarding some bits, then some indications in the UEI can be discarded. Alternatively, the aforementioned parameter information in the UEI indication can be understood as having a priority order. Therefore, the bits can be discarded according to the priority order of the multiple parameter information. For example, if the priority order of the multiple parameter information is: scheduling mode > payload size > event type, etc., then when further indication bits need to be discarded, the event type indication bits can be discarded to satisfy the transmission restrictions.

[0293] In addition, parameters such as cyclic shift can be used to determine whether the first indication information includes UEI.

[0294] For example, the first indication information includes: HARQ response and UEI. If the HARQ response is PUCCH 0 and the UEI is PUCCH 0 / 1, then the SR and HARQ response can be distinguished by adding an offset value to the MCS used in the cyclic shift. For example, if the offset value is 2, the MCS used for SR+HARQ ACK is 0,3,6,9. Then the MCS used for HARQ ACK+UEI is 2,5,8,11. Or, if the MCS is 2,5,8,11, then it can be determined that the first indication information includes UEI.

[0295] Step 203: The terminal device sends a beam report through the second channel.

[0296] The terminal device sends a beam report via the second channel. Correspondingly, the network device receives the beam report via the second channel.

[0297] The beam report in this application embodiment may include at least one of the following: the identifier of the reference signal corresponding to the beam / beam, the measured value of the reference signal, the number of reference signals, and the configuration of the reference signal (e.g., at least one of the following: the time domain resources used by the beam / reference signal, the associated CC resources, and an identifier indicating whether it is a multi-CC), etc., and the specific details are not limited here.

[0298] In this context, the reference signal is event-dependent. Alternatively, it can be understood that different events correspond to different reference signals / beams.

[0299] Specifically, after the terminal device sends the first indication information to the network device through the first channel, it sends a beam report to the network device through the second channel.

[0300] Accordingly, after receiving the first indication information, the network device can correctly parse the beam report from the second channel based on the parameter information indicated by the first indication information.

[0301] Optionally, if the periods or time-domain offsets of the first indication information corresponding to different scheduling modes are different, or if the periods or time-domain offsets of the beam reports corresponding to different scheduling modes are different, then after receiving the first indication information or beam reports, the network device can determine the scheduling mode supported by the terminal device based on the first indication information or beam reports. For example, as described above... Figure 3A and Figure 3B Examples are shown in the text.

[0302] For example, the first indication information is used to indicate that the scheduling mode supported by the terminal device is dynamic scheduling. Then, the network device can send the resources used for beam reports to the terminal device. The network device then uses these resources to transmit beam reports. Correspondingly, the network device receives beam reports sent by the terminal device on these resources.

[0303] For example, if the first indication information indicates that the scheduling mode supported by the terminal device is pre-configured scheduling, then the network device does not need to send a DCI to the terminal device to indicate the resources used by the beam report.

[0304] For example, the first indication information is used to instruct the network device not to send the resources used for beam reporting. Therefore, the network device does not need to send a DCI to the terminal device to indicate the resources used for beam reporting.

[0305] For example, Figure 3C An example relationship between the first indication information carried by the first channel and the beam report carried by the second channel is given. For example, the first indication information is used to indicate the scheduling mode, event 1, event 2, and the payload size (payloadX) of the beam report. Then the payload size of the beam report carried by the second channel is payloadX, and the beams in the beam report are associated with the events in the first indication information. For example, event 1 is associated with beam 1 and beam 2, etc., and event 2 is associated with beam A and beam B, etc.

[0306] It can be seen that, on the one hand, the terminal device actively initiates the transmission of beam reports so that the network device can understand the beam performance of the terminal device in a timely manner. Specifically, the terminal device reports first indication information to the network device through the first channel and reports the beam report of the reference signal through the second channel. The beam report includes the measured value and configuration of the reference signal, which is event-related. This method not only allows the network device to perceive changes on the terminal side in a timely manner through beam reports, but also helps the network device to complete the detection and identification of beam report signaling with lower processing complexity using the first indication information. On the other hand, the terminal device directly or indirectly indicates the supported scheduling mode through the first indication information. The network device can determine whether to allocate resources for subsequent beam reports based on the scheduling mode indicated by the first indication information, thereby reducing unnecessary resource allocation. Furthermore, the terminal device reports the payload size of subsequent beam reports through the first indication information, thereby reducing blind detection of the subsequent second channel by the network device.

[0307] The communication method in the embodiments of this application has been described above. The communication device in the embodiments of this application is described below. Please refer to [link / reference]. Figure 4This application provides an embodiment of the communication device 400.
