[0002] The present application relates to the field of communication, in particular to a communication method and related apparatus. BACKGROUND

[0003] 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, the terminal device can access the network device and receive scheduling and indication information of the network device to realize wireless communication.

[0004] Currently, the network device configures a resource of a beam for the terminal device, the terminal device performs beam measurement using the resource, and reports a beam report of the beam.

[0005] 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

[0006] 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 not only perceive changes on the terminal side in a timely manner, but also facilitate the network device to detect and identify beam report signaling with lower processing complexity through the first indication information.

[0007] The 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 processors, chips or chip systems, 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.

[0008] 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 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 not only timely perceive terminal-side changes through the beam report, but also facilitate the network device to complete detection and identification of beam report signaling with lower processing complexity through the first indication information.

[0009] Optionally, in a possible implementation manner 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 resources for the beam report; the terminal device is further configured to receive second indication information, the second indication information being used to indicate the resources for the beam report; and the terminal device is configured to send the beam report to the network device through the second channel on the resources.

[0010] In this possible implementation manner, the terminal device requests the resources for the beam report through the first indication information, so that the network device explicitly needs to indicate the resources for the terminal device to report the beam report, thereby realizing dynamic scheduling of the beam report.

[0011] The second aspect of the present application provides a communication method, which is executed by a network device, or executed by part of components (such as processors, chips or chip systems, etc.) in the network device, or the method can also be implemented by a logic module or software that can realize all or part of the functions of the network device. In the second aspect and its possible implementation manners, the method is described by taking the example of being executed by the network device. In the method, the network device receives first indication information sent by a terminal device through a first channel, the first indication information being used to indicate at least one parameter information, and the at least one parameter information at least including an identifier of an event. The network device receives a beam report sent by the terminal device through a second channel, the beam report including a measurement value of a reference signal and a configuration of the reference signal, and the reference signal being related to the event.

[0012] Based on the above scheme, the network device receives first indication information reported by a terminal device through a first channel, and receives 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 not only timely perceive terminal-side changes through the beam report, but also facilitate the network device to complete detection and identification of beam report signaling with lower processing complexity through the first indication information.

[0013] Optionally, in a possible implementation manner of the second aspect, the scheduling mode supported by the terminal device is dynamic scheduling, and the first indication information is further used for requesting a resource for the beam report. The method further includes: the network device sending second indication information to the terminal device, the second indication information being used for indicating the resource for the beam report.

[0014] In this possible implementation manner, the network device explicitly needs to indicate the resource for the terminal device to report the beam report through the first indication information, so that dynamic scheduling of the beam report can be implemented.

[0015] Optionally, in a possible implementation manner of the second aspect, the network device determines the scheduling mode supported by the terminal device based on the first indication information or the beam report. For example, the network device can determine the scheduling mode supported by the terminal device through a period or a time domain offset of the first indication information. For another example, the network device can determine the scheduling mode supported by the terminal device through a period or a time domain offset of the beam report.

[0016] In this possible implementation manner, the network device can explicitly determine the scheduling mode supported by the terminal device through the first indication information or the beam report, so that the overhead of an additional indication bit indicating the scheduling mode is reduced.

[0017] Optionally, in a possible implementation manner of the first aspect or the second aspect, the scheduling mode supported by the terminal device is dynamic scheduling, and the first indication information is further used for requesting a resource for the beam report.

[0019] Optionally, in a possible implementation manner of the first aspect or the second aspect, the scheduling mode supported by the terminal device is preconfigured scheduling, and the first indication information is further used for notifying the network device to receive the beam report on a preconfigured resource.

[0020] In this possible implementation manner, the network device can determine to receive the beam report on the preconfigured resource through the first indication information, without the need to indicate the resource for the beam report through the downlink control information, so that the overhead of the additional downlink control information is reduced on the premise of ensuring correct reception of the beam report.

[0021] Optionally, in a possible implementation manner of the first aspect or the second aspect, the scheduling mode supported by the terminal device is dynamic scheduling, the first indication information is further used for requesting a resource for the beam report, and the second indication information is used for confirming the resource for the beam report requested by the first indication information or is used for issuing the resource for the beam report.

In the technical solutions provided in the embodiments of the present application, the device for implementing the function of the network device is taken as an example to describe the technical solutions provided in the embodiments of the present application.

[0125] 3. Configuration and pre-configuration

[0126] In the present application, both configuration and pre-configuration will be used. Among them, the configuration refers to that the network device / server sends some parameter configuration information or parameter values to the terminal device through messages or signaling, so that the terminal device determines the communication parameters or the resources in the transmission according to the values or information. The pre-configuration is similar to the configuration, which can be the parameter information or parameter values agreed by the network device / server and the terminal device in advance, or the parameter information or parameter values adopted by the base station / network device or the terminal device according to the standard protocol, or the parameter information or parameter values pre-stored in the base station / server or the terminal device. The present application does not limit this.

[0127] Further, these values and parameters can be changed or updated.

[0128] 4、The terms "system" and "network" in the embodiments of the present application can be used interchangeably. "At least one" means one or more, and "multiple" means two or more. "And / or" describes the association relationship of associated objects, which means that there can be three relationships, for example, A and / or B can represent the following cases: A exists alone, B exists alone, A and B exist together, where A and B can be singular or plural. The character " / " generally represents an "or" relationship between the associated objects. "At least one of the following" or similar expressions means any combination of these items, including any combination of single or multiple 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 together, A and C exist together, B and C exist together, A, B and C exist together. In addition, unless otherwise specified, the ordinal numbers "first", "second", etc. mentioned in the embodiments of the present application are used to distinguish multiple objects, and are not used to limit the order, time sequence, priority or importance of the multiple objects.

[0129] 5、In the embodiments of the present application, "sending" and "receiving" represent the direction of signal transmission. For example, "sending information to XX" can be understood as that the destination of the information is XX, which can include direct sending through the air interface, or indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as that the source of the information is YY, which can include direct receiving from YY through the air interface, or indirect receiving from YY through the air interface by other units or modules. "Sending" can also be understood as "output" of a chip interface, and "receiving" can also be understood as "input" of a chip interface. For another example, "sending" can also be understood as output of a baseband part to a radio frequency part inside a device, and "receiving" can also be understood as receiving of the baseband part output by the radio frequency part inside the device.

[0130] In other words, sending and receiving can be between devices, such as between network devices and terminal devices, or can be within a device, such as between components, modules, chips, software modules or hardware modules within a device through a bus, wire or interface.

[0131] It can be understood that the information between the source and the destination of the information transmission can be processed as necessary, such as encoding and modulation, but the destination can understand the valid information from the source. Similar expressions in the present application can be understood similarly, and will not be repeated here.

[0132] In the embodiments of the present application, transmission includes sending and / or receiving. That is, transmission can be sending, or receiving, or both sending and receiving, which is not limited here.

[0133] In addition, the receiving can also be understood as detecting, monitoring, etc., which are not limited here. For example, for receiving DCI, it usually means monitoring DCI.

[0134] 6. In this application, "for indicating" can include for directly indicating and for indirectly indicating. When describing that certain indication information is for indicating A, it can be understood as that the indication information carries A, directly indicates A or indirectly indicates A.

[0135] In this application, the information indicated by the indication information is referred to as the to-be-indicated information. In the specific implementation process, there are many ways to indicate the to-be-indicated information, for example, it can be realized by a direct indication method, such as indicating by the to-be-indicated information itself or the index of the to-be-indicated information. It can also be realized by an indirect indication method by indicating other information, where the other information has an association relationship with the to-be-indicated information. It can also only indicate part of the to-be-indicated information, and the other part of the to-be-indicated information is known or agreed in advance. For example, the indication of a specific information can also be realized by means of the pre-agreed (for example, the protocol stipulates) arrangement order of each information, thereby reducing the indication overhead to a certain extent.

[0136] The to-be-indicated information can be sent as a whole, or can be sent separately into multiple sub-information, and the sending period and / or sending occasion of the sub-information can be the same or different. The specific sending method is not limited in this application. The sending period and / or sending occasion of the sub-information can be pre-defined, for example, pre-defined according to the protocol, or can be configured by the transmitting end device to the receiving end device. The configuration information may, for example, but not limited to, include one or a combination of at least two of RRC signaling, medium access control (MAC) layer signaling and physical layer signaling. The MAC layer signaling may, for example, include MAC CE; the physical layer signaling may, for example, include downlink control information (DCI).

[0137] In the present application, the same or similar parts among various embodiments can be mutually referred to, unless otherwise specified. In the present application, the terms and / or descriptions among different embodiments, and among various implementation manners / implementation methods / realization methods in each embodiment have consistency and can be mutually referred to, unless otherwise specified and in conflict with logic. The technical features in different embodiments, and in various implementation manners / implementation methods / realization methods in each embodiment can be combined to form new embodiments, implementation manners, implementation methods, or realization methods according to their inherent logical relationship. The following implementation manners of the present application do not constitute a limitation on the protection scope of the present application.

[0138] In order to facilitate understanding of the method provided by the embodiments of the present application, the system architecture of the method provided by the embodiments of the present application will be described below. It can be understood that the system architecture described in the embodiments of the present application is used to more clearly illustrate the scheme of the embodiments of the present application, and does not constitute a limitation on the scheme provided by the embodiments of the present application.

[0139] Please refer to FIG. 1A, which is a schematic diagram of the architecture of a communication system 1000 applied by the embodiments of the present application. As shown in FIG. 1A, the communication system 1000 includes a radio access network (RAN) 100 and a core network 200. Optionally, the communication system 1000 can also include the Internet 300. The RAN 100 includes at least one RAN node (such as 110a and 110b in FIG. 1A, collectively referred to as 110), and can also include at least one terminal device (such as 120a-120j in FIG. 1A, collectively referred to as 120). The RAN 100 can also include other RAN nodes, such as wireless relay devices and / or wireless backhaul devices (not shown in FIG. 1A). The terminal devices 120 are connected to the RAN nodes 110 in a wireless manner, and the RAN nodes 110 are connected to the core network 200 in a wireless or wired manner. The core network devices in the core network 200 and the RAN nodes 110 in the RAN 100 can be independent and different physical devices, or can be the same physical device integrated with the logical functions of the core network devices and the logical functions of the RAN nodes. The terminal devices and the terminal devices, and the RAN nodes and the RAN nodes can be connected to each other in a wired or wireless manner.

[0140] The RAN 100 can be an evolved universal terrestrial radio access (E-UTRA) system, a NR system, or a future wireless access system defined in 3GPP. The RAN 100 can also include two or more different wireless access systems. The RAN 100 can also be an open RAN (O-RAN).

[0141] A RAN node, also referred to as a radio access network device, a RAN entity, or an access node, is used to help terminal devices access a communication system through wireless means. In one application scenario, the RAN node can be a base station, an evolved NodeB (eNodeB), a transmission reception point (TRP), a next generation NodeB (gNB) in a 5th generation (5G) mobile communication system, a next generation NodeB in a 6th generation (6G) mobile communication system, or a base station in a future mobile communication system. The RAN node can be a macro base station (such as 110a in FIG. 1A), a micro base station, or an indoor station (such as 110b in FIG. 1A), a relay node, or a donor node.

[0142] In another application scenario, a terminal device can access a network through cooperation of a plurality of RAN nodes, and different RAN nodes implement part of functions of a base station. For example, a RAN node can be a central unit (CU), a distributed unit (DU), or a radio unit (RU). The CU here implements functions of a radio resource control protocol and a packet data convergence protocol (PDCP) of the base station, and can also implement a function of a service data adaptation protocol (SDAP); the DU implements functions of a radio link control layer and a medium access control (MAC) layer of the base station, and can also implement part of a physical layer or all of a physical layer; and specific descriptions about the protocol layers can be referred to related technical specifications of the 3GPP. The RU can be used to implement functions of transceiving a radio frequency signal. The CU and the DU can be two independent RAN nodes, or can be integrated in a same RAN node, for example, integrated in a baseband unit (BBU). The RU can be included in a radio frequency device, for example, included in a remote radio unit (RRU) or an active antenna unit (AAU). The CU can be further divided into two types of RAN nodes, a CU-control plane and a CU-user plane.

[0143] In different systems, a RAN node can have different names. For example, in an O-RAN system, a CU can be referred to as an open CU (O-CU), a DU can be referred to as an open DU (O-DU), and an RU can be referred to as an open RU (O-RU). The RAN node in the embodiments of the present application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module. For example, the RAN node can be a server loaded with a corresponding software module. The embodiments of the present application do not limit specific technologies and specific device forms adopted by the RAN node.

[0144] In addition, the RAN node can also be referred to as a network device, which is a device deployed in a wireless access network to provide wireless communication functions for terminal devices. The network device can include various forms of macro base stations, micro base stations (also known as small stations), relay stations, access points, etc. In systems using different wireless access technologies, the names of network devices can be different, such as eNB or eNodeB (Evolutional NodeB) in Long Term Evolution (LTE). The network device can also be a wireless controller in a cloud radio access network (CRAN) scenario. The network device can also be a base station device in a future 5G network or a network device in a future evolved PLMN network. The network device can also be a wearable device or a vehicle-mounted device. The network device can also be a transmission and reception point (TRP). In addition, in a network structure, the network device can include a centralized unit (CU) node, or a distributed unit (DU) node, or a RAN device including a CU node and a DU node. For ease of description, a base station is described as an example of a RAN node below.

[0145] A terminal device is a device with wireless transceiver function, which can transmit signals to a base station or receive signals from a base station. The terminal device can also be referred to as a terminal device, user equipment (UE), mobile station, mobile terminal device, etc. The terminal device can be widely applied in various scenarios, such as device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), internet of things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, remote medical treatment, smart power grid, smart furniture, smart office, smart wear, smart transportation, smart city, etc. The terminal device can be a mobile phone, tablet computer, computer with wireless transceiver function, wearable device, vehicle, aircraft, ship, robot, mechanical arm, smart home device, etc. Embodiments of the present application do not limit the specific technology and specific device form of the terminal device.

[0146] The base stations and the terminal devices can be fixed in position or mobile. The base stations and the terminal devices can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on water; can also be deployed on airplanes, balloons and artificial satellites. Embodiments of the present application do not limit the application scenarios of the base stations and the terminal devices.

[0147] The roles of the base stations and the terminal devices can be relative, for example, the helicopter or the unmanned aerial vehicle 120i in FIG. 1A can be configured as a mobile base station, and for those terminal devices 120j that access the wireless access network 100 through 120i, the terminal device 120i is a base station; but for the base station 110a, 120i is a terminal device, that is, 110a communicates with 120i through a wireless air interface protocol. Of course, 110a and 120i can also communicate through a base station-to-base station interface protocol, and in this case, 120i is also a base station relative to 110a. Therefore, the base stations and the terminal devices can be collectively referred to as communication devices, 110a and 110b in FIG. 1A can be referred to as communication devices with base station functions, and 120a-120j in FIG. 1A can be referred to as communication devices with terminal device functions.

[0148] The base stations and the terminal devices, the base stations and the base stations, and the terminal devices and the terminal devices can communicate through licensed frequency spectrum, can communicate through unlicensed frequency spectrum, and can also communicate through licensed frequency spectrum and unlicensed frequency spectrum at the same time; can communicate through frequency spectrum below 6 gigahertz (GHz), can communicate through frequency spectrum above 6 GHz, and can also communicate through frequency spectrum below 6 GHz and frequency spectrum above 6 GHz at the same time. Embodiments of the present application do not limit the frequency spectrum resources used for wireless communication.

[0149] In embodiments of the present application, the functions of the base station can also be performed by a module (such as a chip) in the base station, or by a control subsystem containing base station functions. The control subsystem containing base station functions herein can be a control center in the above-mentioned application scenarios such as smart grid, industrial control, intelligent transportation and smart city. The functions of the terminal device can also be performed by a module (such as a chip or a modem) in the terminal device, or by a device containing terminal device functions.

[0150] It can be understood that the RAN 100 has been described above to include at least one RAN node (such as 110a and 110b in FIG. 1A, collectively referred to as 110) and at least one terminal device (such as 120a-120j in FIG. 1A, collectively referred to as 120).

[0151] In one possible implementation, the communication system shown in FIG. 1A can also be shown as in FIG. 1B, i.e., including one RAN node 110 and multiple terminal devices (e.g., 120A and 120B in FIG. 1B). In this case, the single RAN node can transmit data or control signaling to a single or multiple terminal devices.

[0152] In another possible implementation, the communication system shown in FIG. 1A can also be shown as in FIG. 1C, i.e., including multiple RAN nodes (e.g., 110A, 110B and 110C in FIG. 1C) 110 and one terminal device 120. In this case, the multiple RAN nodes can also transmit data or control signaling to the single terminal device at the same time.

[0153] In the beam management process, the network device configures the terminal device with the resource of the beam, the terminal device uses the resource to perform beam measurement, and reports the beam report of the beam. However, in the current beam measurement scenario, the behavior of the terminal device is controlled by the network device (or understood as the terminal device will perform beam measurement and report according to the configuration or indication of the network device), and the measurement period of the beam is long, which causes that the beam report received by the network device cannot timely describe the change on the terminal side, that is, the network device can not timely discover the change of the beam quality on the terminal side.

[0154] To solve the above technical problems, the embodiment of the present application provides a communication method, the terminal device reports first indication information to the network device through a first channel, and reports a beam report of a reference signal through a second channel. And the beam report includes a measurement value of the reference signal and a configuration of the reference signal, and the reference signal is related to an event. Through this way, not only the network device can timely perceive the change on the terminal side through the beam report, but also the network device can complete the detection and identification of the beam report signaling with lower processing complexity through the first indication information.

[0155] Please refer to FIG. 2, the embodiment of the present application provides a flowchart of the communication method, which can include steps 201 to 203. Steps 201 to 203 can be executed by a communication device (network device and / or terminal device), or can be executed by part of components (such as processor, chip or chip system, etc.) in the communication device, or can be realized by a logic module or software which can realize all or part of the function of the communication device. The following takes the execution of the network device and the terminal device as an example for description. The processing executed by a single execution subject in steps 201 to 203 can also be divided into execution by multiple execution subjects, which can be logically and / or physically separated. For example, in the case that the communication device is the network device, the processing executed by the communication device can be divided into execution by at least one of the CU, the DU and the RU. The following describes steps 201 to 203 in detail.

[0156] At step 201, the network device sends a reference signal to the terminal device. This step is optional.

[0157] 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.

[0158] The reference signal can be a reference signal with a transmission period, or a reference signal without a transmission period, etc., which is not limited here.

[0159] Optionally, the reference signal corresponds to a corresponding beam, or it is understood that the reference signal is used for beam measurement.

[0160] Further, after the terminal device receives the reference signal, the terminal device measures the reference signal to obtain a corresponding measurement value. The measurement value can include at least one of the following: reference signal receiving power (RSRP), reference signal receiving quality (RSRQ), signal to interference plus noise ratio (SINR), channel quality indicator (CQI), etc.

[0161] Optionally, after the reference signal satisfies the triggering condition of the event, the subsequent step 202 is executed. Of course, step 202 can also have no causal relationship with step 201, which is not limited here. The event will be described later, which will not be expanded here.

[0162] At step 202, the terminal device sends first indication information through a first channel.

[0163] The terminal device sends first indication information through a first channel. Correspondingly, the network device receives the first indication information through the first channel.

[0164] The first indication information is used to indicate at least one parameter information, and the at least one parameter information at least includes the identification of the event. The first channel can include at least one of the following: uplink physical control channel (PUCCH) or uplink physical shared channel (PUSCH), etc.

[0165] In the embodiments of the present application, the identifier of the event is used to distinguish different events, or to distinguish different types of events. Alternatively, it is understood that the identifiers of the same type of event can be the same or different. Subsequently, the type of event is exemplarily described by taking the identifier of the event as an example.

[0166] The type of event can include at least one of event1, event2, event7a, event7b, and the like.

[0167] For example, event1 means that the quality of the beam is lower than a threshold. For another example, event2 means that the quality of at least one new beam is better than the quality of the current beam plus a threshold. For another example, event7a means that the quality of at least one new beam is better than the quality of the worst reference signal in the reference signal associated with the activated TCI state plus a threshold. For another example, event7b means that the quality of at least one new beam is better than the quality of the best reference signal in the reference signal associated with the activated TCI state plus a threshold. The quality of the beam can be represented by L1-RSRP, L1-SINR, and the like, which are various measurement values in the foregoing step 201. The representation of the quality of the beam is not limited specifically.

[0168] The first indication information in the embodiments of the present application can be uplink control information (UCI), or can be first indication information including UCI and other information, and the like, which is not limited specifically herein.

[0169] Optionally, in order to improve the efficiency of the network device 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, and is also used to determine the second part. The second part includes part or all of the parameter information of at least one parameter information, which will be described later, and will not be expanded here. Alternatively, it is understood that the first part in the first indication information is used for the network device to correctly parse the second part or the beam report.

[0170] The manner in which the first indication information or the first part indicates the scheduling mode can be direct indication, or indirect indication according to a period and the like (which will be exemplarily described later. It will not be expanded here), which is not limited specifically herein.

[0171] Further, 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 different. For example, if the first part corresponding to different scheduling modes is different, the network device can determine which scheduling mode is supported by the terminal device through the different first parts, thereby reducing the indication bits of the indication of the scheduling mode.

[0172] Optionally, the scheduling mode can also be related to a second channel carrying a subsequent beam report. For example, if dynamic scheduling requires higher reliability, the second channel can be a PUCCH.

[0173] The "correlation" or "association" involved in the embodiments of the present application can be understood as a preset association relationship or mapping relationship, which can be an association relationship / mapping relationship agreed by the network device and the terminal device in advance, or an association relationship / mapping relationship adopted by the network device or the terminal device according to a standard protocol, or an association relationship / mapping relationship pre-stored in the network device or the terminal device. The present application does not limit this.

[0174] For example, the first part is specifically used to determine at least one of the bit length of the second part, the parameter information indicated by the second part, and the cyclic redundancy check (CRC) used by the second part. Alternatively, after the network device receives the first indication information, the first part can be parsed first, and then at least one of the bit length of the second part, the CRC used by the second part, and the specific parameter information indicated by the second part is determined according to the parsing result of the first part. The present application does not limit this.

[0175] The scheduling mode in the embodiments of the present application includes dynamic scheduling and pre-configuration scheduling. The dynamic scheduling is related to DCI, and the pre-configuration scheduling is not related to DCI, and the DCI is used to indicate the resource used for the beam report. For example, under dynamic scheduling, the first indication information can affect the parsing of the DCI.

[0176] The dynamic scheduling can be understood as a scheduling mode in which the network device dynamically configures the resource used for the beam report by using the DCI. The pre-configuration scheduling can be understood as a scheduling mode in which the network device does not indicate the resource used for the beam report by using the DCI.

[0177] Next, the scheduling process corresponding to different scheduling modes is described. For convenience of description, mode A is taken as an example to describe the dynamic scheduling, and mode B is taken as an example to describe the pre-configuration scheduling.

[0178] 1. Mode A includes at least three steps, which are as follows:

[0179] Step 1: The terminal device sends a first PUCCH (one bit / multiple bits) to request the resource of a second UL channel to carry a beam report (request the resource used for the beam report). FFS: Request format, such as SR or new UCI type.

[0180] Step 2, the network device sends DCI, and the terminal device detects the DCI format to indicate the resource of the second UL channel carrying the beam report.

[0181] Step 3, the terminal device transmits the beam report in the second UL channel. The second UL channel can include PUCCH and / or PUSCH.

[0182] 2, mode B includes 2 steps, which are respectively:

[0183] Step 1, the terminal device sends the first PUCCH (one bit / multiple bits) to inform the second UL channel carrying the beam report (inform which resource carries the beam report). FFS: notification format, such as SR or new UCI type.

[0184] Step 2, the terminal device sends the beam report in the second UL channel. FFS: detailed information of the second UL channel, for example, whether the second UL channel is PUCCH, PUSCH or both.

[0185] In a possible implementation manner, the terminal device supports dynamic scheduling, and the first indication information is further used to request the resource for the beam report. Alternatively, it is understood that the first indication information is used to request the resource for the second channel.

[0186] In another possible implementation manner, the terminal device supports dynamic scheduling, the first indication information is further used to request the resource for the beam report, and the second indication information is used to confirm the resource for the beam report requested by the first indication information or to issue the resource for the beam report. Correspondingly, after receiving the first indication information, the network device can send the second indication information to the terminal device, and the second indication information is used to confirm the resource for the beam report requested by the first indication information or to issue the resource for the beam report.

[0187] In another possible implementation manner, the terminal device supports pre-configuration scheduling, and the first indication information is further used to inform the network device not to issue the resource for the beam report. Alternatively, it is understood that the first indication information is used to inform to use the pre-configuration resource for the second channel.

[0188] It can be understood that the terminal device can only support dynamic scheduling, can only support pre-configuration scheduling, or can support both dynamic scheduling and pre-configuration scheduling. In this case, different scheduling modes can correspond to corresponding resources.

[0189] Optionally, different scheduling modes correspond to different parameter information, or different scheduling modes correspond to different first indication information, or different scheduling modes correspond to different beam reports. In this way, after the network device determines the scheduling mode supported by the terminal device, the corresponding parameter information or first indication information can be determined according to the scheduling mode. Or the scheduling mode supported by the terminal device can be determined according to the parameter information or the first indication information.

[0190] For example, the different scheduling modes corresponding to different beam reports include at least one of the following: the identities of the reference signals corresponding to different scheduling modes are different, the quantities of the reference signals corresponding to different scheduling modes are different, and the configurations of the reference signals corresponding to different scheduling modes are different.

[0191] Further, the time domain periods of the first indication information / beam reports corresponding to different scheduling modes are different. Or, the time domain offsets of the first indication information / beam reports corresponding to different scheduling modes are different. Or, it is understood that the first indication information or the first part of the indication mode is indirectly indicated.

[0192] The time domain period or the time domain offset of the first indication information corresponding to the scheduling mode is exemplarily described below. In actual application, the time domain period or the time domain offset of the beam report corresponding to the scheduling mode can also be used, which is not limited here.

[0193] For example, as shown in FIG. 3A, if the time domain period of the first indication information is 2 slots (i.e., the first indication information is transmitted on slot 1, slot 3, slot 5, and slot 7, etc.), the scheduling mode supported by the terminal device is mode A. If the time domain period of the first indication information is 5 slots (i.e., the first indication information is transmitted on slot 0 and slot 4, etc.), the scheduling mode supported by the terminal device is mode B. Thus, the network device can determine the scheduling mode supported or indirectly indicated by the terminal device according to the period of the first indication information.

[0194] For example, if the periods of the first indication information corresponding to different scheduling modes are the same, the terminal device can be determined to support which scheduling mode according to the different time domain offsets. Or, it is understood that different scheduling modes can be distinguished according to the different periods of the first indication information, or different scheduling modes can be distinguished according to whether the periods are offset from the reference period, or different scheduling modes can be distinguished according to the different offset values from the reference period.

[0195] For example, as shown in FIG. 3B, the periodicity of the first indication information corresponding to different scheduling modes is 2 slots. For example, assuming that the reference is 0246, the first indication information is periodically transmitted on slot 1, slot 3, slot 5 and slot 7, and the time domain offset of the first indication information is 1, and it can be determined that the scheduling mode supported by the terminal device corresponding to the time domain offset of 1 is mode A. The first indication information is periodically transmitted on slot 0, slot 2, slot 4 and slot 6, and the time domain offset of the first indication information is 0, and it can be determined that the scheduling mode supported by the terminal device corresponding to the time domain offset of 0 is mode B.

[0196] Optionally, the at least one parameter information is related to the content of the beam report. In this way, the network device can know the content of the beam report after receiving the first indication information, thereby improving the efficiency of the network device in analyzing the beam report and reducing the blind detection complexity.

[0197] In the embodiments of the present application, the at least one parameter information includes at least one of the following:

[0198] 1. The scheduling mode supported by the terminal device (which can be referred to as parameter 1 in the following). The scheduling mode includes the dynamic scheduling and the pre-configuration scheduling mentioned above.

[0199] 2. The identification of the event associated with the scheduling mode (which can be referred to as parameter 2 in the following). For example, the dynamic scheduling is associated with a first event, and the pre-configuration scheduling is associated with a second event.

[0200] 3. The beam information related to the event (which can be referred to as parameter 3 in the following).

[0201] 4. The payload size related to the beam report or the interval to which the payload size belongs (which can be referred to as parameter 4 in the following).

[0202] 5. The second channel is PUCCH or PUSCH (which can be referred to as parameter 5 in the following).

[0203] 6. The resource used by the second channel (which can be referred to as parameter 6 in the following), and the like.

[0204] Optionally, different scheduling modes can correspond to different parameter information or first indication information. In this way, after the network device receives the first indication information, the scheduling mode supported by the terminal device can be determined first, and then the corresponding parameter information or first indication information can be determined according to the scheduling mode. Therefore, the network device can improve the efficiency of analyzing the beam report and reduce the blind detection complexity according to the parameter information. Alternatively, the first indication information or the parameter information in the first indication information is determined first, and then the scheduling mode supported by the terminal device is determined according to the first indication information or the parameter information. Therefore, the network device can determine whether it is necessary to issue the DCI indicating the resource used for the beam report according to the scheduling mode supported by the terminal device.

[0205] For the convenience of understanding, the above-mentioned various parameter information is described by way of example in the first case of the indication mode.

[0206] In the embodiment of the present application, there are various ways for the first indication information to indicate the at least one parameter information, for example, the first indication information indicates the at least one parameter information by N bits. For another example, the first indication information indicates the at least one parameter information by the orthogonal cover code (OCC) or cyclic shift used by the first indication information, etc. Wherein, N is an integer greater than or equal to 1. Subsequently, different indication modes are described by two cases.

[0207] The first case: the first indication information indicates the at least one parameter information by N bits.

[0208] In this case, the first indication information includes N bits, that is, the first indication information can include 1 bit, can include 2 bits, can include more than 2 bits, etc., which is not limited here.

[0209] Wherein, at least one bit corresponds to one or more indication bits. Or it can be understood that the first indication information includes at least one indication bit. Each indication bit corresponds to at least one bit.

[0210] For example, the first indication information includes 1 bit, and the terminal device is preset with a resource corresponding to the identification of the event. Thus, the type of the event and the corresponding resource of the subsequent second channel can be indicated by indicating 1 bit. For example, taking the identification of the event to represent the type of the event as an example, the first indication information is "0", which represents that the type of the event is 1, and the event of type 1 is associated with resource 1. For another example, the first indication information is "1", which represents that the type of the event is 2, and the event of type 2 is associated with resource 2. Further, the network device can determine on which resources to receive the beam report and the type of the event related to the beam information in the beam report through the first indication information.

[0211] Optionally, in the case where the number of the at least one parameter information is multiple, the multiple parameter information respectively corresponds to different indication bits (that is, the multiple parameter information is indicated by independent bits), or at least two parameter information in the multiple parameter information share the same indication bit, etc., which is not limited here.

[0212] Optionally, the bit length of the first indication information is related to the CRC used by the first indication information, or the combination mode of each parameter information in the first indication information is related to the CRC. Thus, the complexity of the network device blind detection of the first indication information can be reduced.

[0213] Exemplarily, different bit lengths correspond to different CRCs. Alternatively, different combinations of the multiple indication bits correspond to different CRCs. The combinations of the multiple indication bits will be described in detail later, which will not be expanded here. In this way, the blind detection complexity of the network device can be reduced, and different CRCs can be used to distinguish the first indication information of different bit lengths, or different CRCs can be used to distinguish the combinations of the multiple indication bits.

[0214] The above various parameter information will be explained below taking the first case as an example.

[0215] 1. Explanation of parameter 1.

[0216] Optionally, the terminal device can indicate the scheduling mode supported by the terminal device through the parameter 1.

[0217] Further, the event is related to the scheduling mode supported by the terminal device. For example, the network device can determine the scheduling mode supported by the terminal device according to the type of the event. For another example, the network device can determine the type of the event according to the scheduling mode supported by the terminal device.

[0218] For example, the scheduling mode supported by the terminal device is dynamic scheduling, and the first indication information is further used to indicate the resource for the network device to issue the beam report. That is, the network device can also send the resource for the terminal device to send the beam report.

[0219] For another example, the scheduling mode supported by the terminal device is dynamic scheduling, and the first indication information is further used to request the resource for the beam report, and the second indication information is used to confirm the resource for the beam report requested by the first indication information, or is used to issue the resource for the beam report.

[0220] Alternatively, it is understood that the dynamic scheduling is related to the second indication information, the preconfigured scheduling is irrelevant to the second indication information, the second indication information is used to confirm the resource for the beam report requested by the first indication information, or is used to issue the resource for the beam report.

[0221] For another example, the scheduling mode supported by the terminal device is preconfigured scheduling, and the first indication information is further used to indicate that the network device does not need to issue the resource for the beam report.

[0222] For another example, the scheduling mode supported by the terminal device supports both dynamic scheduling and preconfigured scheduling, and the first indication information is further used to indicate that the terminal device supports both scheduling modes, and different scheduling modes are associated with respective scheduling processes and respective resources.

[0223] It can be understood that the parameter 1 can be indicated by a bitmap or the like, which is not limited here.

[0224] For example, the first indication bit can be used to indicate the scheduling mode supported by the terminal device. For example, the first indication bit is "0" to indicate that the terminal device supports pre-configuration scheduling, and the first indication bit is "1" to indicate that the terminal device supports dynamic scheduling. Of course, the first indication bit can also be "0" to indicate that the terminal device supports dynamic scheduling, and the first indication bit can be "1" to indicate that the terminal device supports pre-configuration scheduling.

[0225] For example, the first indication bit can be used to indicate the scheduling mode supported by the terminal device. For example, the first indication bit is "0" to indicate that the terminal device supports pre-configuration scheduling, and the first indication bit is "1" to indicate that the terminal device supports dynamic scheduling. Of course, the first indication bit can also be "0" to indicate that the terminal device supports dynamic scheduling, and the first indication bit can be "1" to indicate that the terminal device supports pre-configuration scheduling.

[0226] For example, the first indication bit can be used to indicate the scheduling mode supported by the terminal device. For example, the first indication bit is "0" to indicate that the terminal device supports pre-configuration scheduling, and the first indication bit is "1" to indicate that the terminal device supports dynamic scheduling. Of course, the first indication bit can also be "0" to indicate that the terminal device supports dynamic scheduling, and the first indication bit can be "1" to indicate that the terminal device supports pre-configuration scheduling.

[0227] For example, the first indication bit can be used to indicate the scheduling mode supported by the terminal device. For example, the first indication bit is "0" to indicate that the terminal device supports pre-configuration scheduling, and the first indication bit is "1" to indicate that the terminal device supports dynamic scheduling. Of course, the first indication bit can also be "0" to indicate that the terminal device supports dynamic scheduling, and the first indication bit can be "1" to indicate that the terminal device supports pre-configuration scheduling.

[0228] It can be seen that through the reporting of parameter 1, the network device can know whether to use mode A or mode B to report the beam. That is, the network device can determine whether to send the DCI in step 2 of mode A according to parameter 1. If the terminal device supports mode B, the network device can carry parameter 1 in the first indication information, so that the network device does not need to send DCI, thereby reducing unnecessary DCI overhead. Of course, if the terminal device supports both mode A and mode B, the network device can send DCI to indicate the resource used for beam reporting corresponding to mode A, and does not need to send DCI to indicate the resource used for beam reporting corresponding to mode B.

[0229] 2. Explanation of parameter 2.

[0230] Optionally, the terminal device can also indicate the event associated with the scheduling mode through parameter 2. Different events can be distinguished by type or identification, etc., which is not limited here.

[0231] Optionally, different scheduling modes are associated with one or more events. Or it is understood that mode A can have a binding relationship with one or more events, and mode B can have a binding relationship with one or more events.

[0232] For example, the dynamic scheduling is associated with a first event, and the pre-configuration scheduling is associated with a second event. The first event and the second event are the same or different, and the number of the first event and the second event is one or more. Wherein, the first event and the second event can be the same in at least one of the following: type, threshold used by the event, etc. The specific is not limited here.

[0233] For example, mode A is associated with event1, and mode B is associated with event2.

[0234] Optionally, the type of the event is related to the bit length of the beam report and / or the content of the beam report (for example, referring to the beam in the beam report). For example, the bit length of the beam report corresponding to different types of events is different. For example, the content of the beam report corresponding to different types of events is different.

[0235] For example, parameter 2 corresponds to a second indication bit in the first indication information. The second indication bit includes at least one bit. The at least one bit can indicate the corresponding event type according to the convention.

[0236] As can be seen, through the reporting of parameter 2, the network device can know the specific event type that causes the triggering of the beam report.

[0237] 3. Explanation of parameter 3.

[0238] Optionally, the terminal device can also indicate the beam information related to the event through parameter 3. Wherein, different events can be distinguished by type or identifier, etc. The specific is not limited here.

[0239] Wherein, the beam information includes at least one of the following: the identifier of the beam associated with the event, the number of beams, the time-frequency resource used by the beam, etc.

[0240] Optionally, the dynamic scheduling is associated with a first event, and the pre-configuration scheduling is associated with a second event. Then the first indication information can also indicate the number of first beams associated with the first event and / or the time-frequency resource of the first beam through parameter 3. The number of second beams associated with the second event and / or the time-frequency resource of the second beam are indicated through parameter 3.

[0241] For example, the event type 1 is associated with the beam 1 and the beam 2. After the network device receives the first indication information and the subsequent beam report, it can be known that the measurement value in the beam report corresponds to which event type. For another example, the beams in the subsequent beam report can not be identified. The network device can determine which beams correspond to which measurement values from the beam report in order through the above association.

[0242] For example, the parameter 3 corresponds to the third indication bit in the first indication information. The third indication bit includes at least one bit. The at least one bit can indicate the corresponding beam quantity or the corresponding time-frequency resource in the order.

[0243] For example, the third indication bit can use 4 bits to describe the beam quantity in the parameter 3. Assuming that the maximum beam quantity configured by RRC is 4, and the event 1+event 2 is involved in the foregoing parameters. For example, the third indication bit can use “0110” to represent the beam quantity corresponding to each event. The first two bits correspond to one event, and the last two bits correspond to another event. The event 1 corresponds to the first two bits “01”, and the event 2 corresponds to the last two bits “10”. That is, the event 1 is associated with 2 beams, and the event 2 is associated with 3 beams.

[0244] It can be seen that through the reporting of the parameter 3, the network device can know what the specific event type is that causes the triggering of the beam report, and which event type the measurement value in the beam report corresponds to, and then determine the measurement value in the beam report. In addition, the terminal device can indicate the beam quantity and / or the time-frequency resource of the beam associated with the event to the network device through the parameter 3. Thus, the subsequent network device can determine the time-frequency location of the beam.

[0245] 4, explanation of the parameter 4.

[0246] Optionally, the terminal device can also indicate the interval to which the subsequent payload size related to the beam report belongs or the size of the payload through the parameter 4.

[0247] It can be understood that the parameter 4 can indicate the interval of the payload, or the size of the payload. The parameter 4 can directly indicate the size of the payload of the beam report, or can jointly indicate the size of the payload of the beam report with other parameters, etc., which is not limited here.

[0248] The parameter 4 jointly indicating the size of the payload of the beam report with other parameters can mean that the parameter 4 in the first indication information indicates an interval, and the specific size of the payload is determined from the interval in combination with other parameters. For example, the other parameters can specifically indicate a value in the RRC configuration. That is, at least two parameter information in the plurality of parameter information jointly indicate the size of the payload of the beam report.

[0249] For example, the fourth indication bit indicates that the payload size is 128 bits by using "10000000". For another example, the fourth indication bit indicates that the interval of the payload size is 1-128 bits by using "01", and the fourth indication bit indicates that the interval of the payload size is 129-256 bits by using "10".

[0250] For example, the fourth indication bit indicates that the payload size is 128 bits by using "10000000". For another example, the fourth indication bit indicates that the interval of the payload size is 1-128 bits by using "01", and the fourth indication bit indicates that the interval of the payload size is 129-256 bits by using "10".

[0251] Further, the interval can also be related to the combination mode of each indication bit in the first indication information. For example, interval 1 corresponds to combination mode 1, and interval 2 corresponds to combination mode 2. Combination mode 1 corresponds to a preset parameter, so that the network device can directly indicate the preset parameter by combination mode 1 in the first indication information, and the related parameters in the first indication information can be omitted.

[0252] It can be seen that the terminal device can indicate the interval or size of the payload of the subsequent beam report to the network device through parameter 4, thereby reducing the blind detection overhead of the network device.

[0253] 5. Explanation of parameter 5.

[0254] Alternatively, since the second channel can be PUCCH or PUSCH, in order for the network device to clearly receive the subsequent beam report from which channel, the terminal device can indicate to the network device whether the second channel is carried on PUCCH or PUSCH through parameter 5.

[0255] Alternatively, the second channel carrying the beam report can also be associated with other parameters.

[0256] For example, the channel carrying the second channel is associated with the aforementioned scheduling mode. For example, dynamic scheduling requires higher reliability, and the second channel can be PUCCH.

[0257] For another example, the channel carrying the second channel is associated with the aforementioned event. For example, the priority of event 2 is higher, and the second channel can be PUCCH.

[0258] For another example, the second channel carrying the beam report is associated with the measurement configuration of multiple different component carriers CC, or the channel carrying the beam report is associated with the component carrier configuration associated with the beam report configuration.

[0259] For example, parameter 5 corresponds to the fifth indication bit in the first indication information. The fifth indication bit includes at least one bit. The at least one bit can indicate the corresponding channel according to an agreement.

[0260] For example, the fifth indication bit can be used to describe whether the second channel is PUCCH or PUSCH with 1 bit. For example, the fifth indication bit is "0" to indicate that the second channel is carried on PUCCH, and the fifth indication bit is "1" to indicate that the second channel is carried on PUSCH. Of course, it can also be that the fifth indication bit is "0" to indicate that the second channel is carried on PUSCH, and the fifth indication bit is "1" to indicate that the second channel is carried on PUCCH.

[0261] It can be seen that the terminal device can indicate to the network device through the parameter 5 whether the subsequent beam report is carried on PUCCH or PUSCH. Thus, the subsequent network device knows which channel to receive the beam report.

[0262] 6. Explanation of parameter 6.

[0263] Optionally, the terminal device can also indicate the resource used by the channel carrying the beam report through the parameter 6. That is, the parameter 6 can indicate the resource of PUCCH, or the resource of PUSCH.

[0264] The resource can include at least one of the following: time domain resource, frequency domain resource, etc. For example, the parameter 6 can indicate the starting position of the time domain resource used by PUCCH and the number of time domain units. For another example, the parameter 6 can indicate the starting position of the time domain resource used by PUSCH and the number of time domain units. For example, the resource can be a channel state information (channel state information, CSI) resource configuration (Resource Setting) used for channel measurement (channel measurement) in the CSI resource configuration, including time-frequency position, code division multiplexing (code division multiplexing, CDM) type, power offset, scrambling code, etc. Configuration.

[0265] The time domain resource in the embodiment of the application can refer to at least one of the following: resource element or resource unit (Resource Element, RE), resource block (Resource Block, RB), interlace, subchannel, RB set, subcarrier, BWP, component carrier, carrier, frequency band, hertz (Hz), kilohertz (kHz), megahertz (MHz), etc. Specific here is not limited.

[0266] The frequency domain resource in the embodiment of the application can refer to at least one of the following: radio frame, subframe, slot, mini-slot, orthogonal frequency division multiplexing (Orthogonal Frequency Division Multiplexing, OFDM) symbol, second, millisecond, microsecond, etc. Specific here is not limited.

[0267] For example, the channel carrying the beam report is associated with multiple different component carriers (CCs).

[0268] For example, the parameter 6 corresponds to the sixth indication bit in the first indication information. The fifth indication bit includes at least one bit. The at least one bit can indicate the corresponding resource according to an agreement. For example, the resource can be indicated by a start position and a length.

[0269] It can be seen that the terminal device can indicate the resource used for the subsequent beam report to the network device through the parameter 6 in the first indication information, thereby improving the efficiency of the network device receiving the beam report.

[0270] The above explanations of various parameters can understand that there can be an association relationship between the above various parameters. The following examples are described. The specific association relationship is not limited here.

[0271] Example 1: The parameter 1 described above describes dynamic scheduling, and the type of event in the parameter 2 is the event type associated with dynamic scheduling. Alternatively, the parameter 1 described above describes pre-configuration scheduling, and the type of event in the parameter 2 is the event type associated with pre-configuration scheduling.

[0272] Example 2: The parameter 2 described above describes event type 1. The parameter 3 describes the beam information related to event type 1.

[0273] Example 3: Different scheduling modes can correspond to different parameter information. For example, if the parameter 1 indicates a dynamic scheduling mode, the first indication information can not include events or beam information associated with pre-configuration scheduling mode, etc. For another example, if the parameter 1 indicates a pre-configuration scheduling mode, the first indication information can not include events or beam information associated with dynamic scheduling mode, etc.

[0274] Example 4: The payload interval indicated by the parameter 4 can be related to the combination mode of each indication bit in the first indication information. For example, the combination mode 1 corresponds to a preset parameter, so that the first indication information can omit the related parameters indicated by the preset parameter, and directly indicate the corresponding parameters indirectly by the combination mode 1.

[0275] Example 5: The payload interval indicated by the parameter 4 can further determine the size of the payload in combination with other parameters.

[0276] The second case: The first indication information indicates at least one parameter information through the transmission parameter of the OCC or the cyclic shift used by the first indication information.

[0277] The transmission parameter can include at least one of OCC, cyclic shift, etc., without being limited specifically herein. Several mapping relationships are described below by way of example:

[0278] For example, the aforementioned parameter 1 (scheduling mode) and parameter 4 (payload size) have a mapping relationship with the cyclic shift.

[0279] For example, Table 1 shows an example of a mapping relationship:

[0280] Table 1

[0281] As can be seen from Table 1, the modulation and coding scheme (MCS) through cyclic shift modulation can indicate the corresponding scheduling mode and payload size. For example, MCS = 0 corresponds to scheduling mode A and payload size payload1. For another example, MCS = 3 corresponds to scheduling mode A and payload size payload2. For another example, MCS = 4 corresponds to scheduling mode B and payload size payload3. For example, MCS = 9 corresponds to scheduling mode B and payload size payload4.

[0282] For example, the aforementioned parameter 1 (scheduling mode) and parameter 5 (second channel of beam report bearer) have a mapping relationship with the OCC. For example, the PUCCH of the second channel has a mapping relationship with the OCC.

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

[0284] Table 2

[0285] Wherein, N represents the sequence number or the number of intra-slot frequency hopping under PUCCH 1 format, and the value of i corresponds to “parameter 1 (scheduling mode) and parameter 6 (second channel of beam report bearer)”. Alternatively, it can be understood that different N and i correspond to different orthogonal sequence values.

[0286] It can be understood that the above several mapping relationships are only examples, and other mapping relationships can also be used in actual applications, without being limited specifically herein.

[0287] In addition, the first indication information can include at least one of the following in addition to at least one of the plurality of parameter information (hereinafter referred to as UEI): hybrid automatic repeat request (HARQ) acknowledgment (ACK) / negative acknowledgment (NACK), scheduling request (SR), CSI, etc.

[0288] Optionally, the priority order of the above-mentioned items is: HARQ acknowledgment> SR> UEI> CSI. For example, in the case that the first indication information cannot be carried in full due to output restrictions and some indications need to be discarded, the priority order can be used for judgment.

[0289] For example, the first indication information includes: HARQ acknowledgment, SR, UEI and CSI. When calculating whether to discard CSI, the number of bits occupied by UEI is counted in the total number of bits of the first indication information, or it is understood that the CSI with lower priority is discarded.

[0290] Further, if part of the bits also need to be discarded according to the transmission limit, part of the indications in the UEI can be discarded. Or it is understood that the plurality of parameter information indicated by the UEI can also have a priority order. Further, the plurality of parameter information can be discarded according to the priority order of the plurality of parameter information. For example, the priority order of the plurality of parameter information is: scheduling mode> payload size> event type, etc. When the indication bit also needs to be discarded, the indication bit of the event type can be discarded to meet the transmission limit.

[0291] In addition, whether the UEI is included in the first indication information can also be determined by a cyclic shift parameter and the like.

[0292] For example, the first indication information includes: HARQ acknowledgment and UEI. If the HARQ acknowledgment is PUCCH 0 and the UEI is PUCCH 0 / 1, the MCS used by the cyclic shift can be used to distinguish SR and HARQ acknowledgment by adding an offset value. For example, the offset value is 2, the MCS used by SR+HARQ ACK=0,3,6,9. Then the MCS used by HARQ ACK+UEI=2,5,8,11. Or it is understood that if the MCS=2,5,8,11, it can be determined that the first indication information includes UEI.

[0293] In step 203, the terminal device sends a beam report through the second channel.

[0294] The terminal device sends a beam report through the second channel. Correspondingly, the network device receives the beam report through the second channel.

[0295] The beam report in the embodiments of the present application can include at least one of the following: an identifier of a reference signal corresponding to a beam, a measurement value of the reference signal, a number of the reference signals, a configuration of the reference signal (for example, at least one of the following: time domain resources used by the beam / reference signal, associated CC resources, an identifier indicating whether it is a multi-CC), and the like, which are not limited here.

[0296] The reference signal is related to the event. Alternatively, it is understood that different events correspond to different reference signals / beams.

[0297] Specifically, after the terminal device sends the first indication information to the network device through the first channel, the terminal device sends the beam report to the network device through the second channel.

[0298] Correspondingly, after receiving the first indication information, the network device can correctly parse the beam report from the second channel according to the parameter information indicated by the first indication information.

[0299] Optionally, if the periodicity or time domain offset of the first indication information corresponding to different scheduling modes is different, or the periodicity or time domain offset of the beam report corresponding to different scheduling modes is different, the network device can determine the scheduling mode supported by the terminal device based on the first indication information or the beam report after receiving the first indication information or the beam report. For example, the examples in FIG. 3A and FIG. 3B.

[0300] 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 resource used for the beam report to the terminal device. Thus the network device transmits the beam report using the resource. Correspondingly, the network device receives the beam report sent by the terminal device on the resource.

[0301] For example, the first indication information is used to indicate that the scheduling mode supported by the terminal device is pre-configuration scheduling. Then the network device does not need to send DCI to the terminal device to indicate the resource used for the beam report.

[0302] For example, the first indication information is used to indicate that the network device does not need to send the resource used for the beam report. Then the network device does not need to send DCI to the terminal device to indicate the resource used for the beam report.

[0303] For example, FIG. 3C shows an example of a relationship between the first indication information carried by the first channel and the beam report carried by the second channel. For example, the first indication information is used to indicate a scheduling mode, event 1, event 2, and a 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 have a correlation relationship with the events in the first indication information. For example, event 1 is associated with beam 1, beam 2, and the like, and event 2 is associated with beam A, beam B, and the like.

[0304] It can be seen that, on the one hand, the terminal device initiatively initiates the sending of the beam report, so that the network device can learn the beam performance of the terminal device in time. Specifically, the terminal device reports the first indication information to the network device through the first channel, and reports the beam report of the reference signal through the second channel. And the beam report includes the measurement value of the reference signal and the configuration of the reference signal, and the reference signal is related to the event. In this way, not only can the network device perceive the terminal side change in time through the beam report, but also the network device can complete the detection and identification of the beam report signaling with lower processing complexity through the first indication information. On the other hand, the terminal device directly or indirectly indicates the supported scheduling mode through the first indication information, and the network device can determine whether to configure resources for subsequent beam reports according to the scheduling mode indicated by the first indication information, thereby reducing unnecessary resource configuration. On the other hand, the terminal device reports the payload size of the subsequent beam report through the first indication information, thereby reducing the blind detection of the network device on the subsequent second channel.
