Description

Information sending method, information receiving method and related devices

[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office on December 18, 2023, with application number 202311750250.2 and application name “Information Sending Method, Information Receiving Method and Related Devices”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of communication technology, and in particular to an information sending method, an information receiving method, and related devices. Background Art

[0003] Fifth-generation mobile communication systems (5G) utilize high-frequency communication, specifically ultra-high frequency (>6 GHz) signals, to transmit data. A major issue with high-frequency communication is that signal energy decreases dramatically with transmission distance, resulting in a short transmission distance. To overcome this, high-frequency communication employs simulated beamforming technology. This technology weights the antenna array to concentrate signal energy within a narrow angular range, creating a beam-like signal (called a simulated beam, or simply beamforming), thereby increasing transmission distance.

[0004] When the terminal device moves at high speed, it is necessary to perform relatively frequent beam switching. The base station configures the terminal device to measure the reference signal. When the base station needs to trigger the terminal device to report the measurement result, the base station can trigger the terminal device to report the measurement result through downlink control information (DCI). The terminal device reports the measurement result to the base station based on the DCI, so that the base station indicates the beam to the terminal device based on the measurement result. The terminal device can switch to the beam, thereby improving the communication quality of the terminal device. In the nineteenth version (release19, R19), it is intended to support beam management actively initiated or event-triggered by the terminal device, but R19 only considers beam management of a single beam. For example, the terminal device actively reports the measurement result for the quality change of the current beam, triggering the base station to perform beam management, thereby timely adjusting the beam used between the terminal device and the network device.

[0005] Currently, solutions for beam management initiated by terminal devices or triggered by events only consider single-beam scenarios. For multi-beam scenarios, how should terminal devices perform beam management to avoid performance loss? Summary of the Invention

[0006] The present application provides an information sending method, an information receiving method, and related devices for enabling a terminal device to send first information to a network device. The method enables a terminal device to proactively report the signal quality or availability of a resource group (also referred to as a co-receiving beam pair or a co-transmitting beam pair) in a multi-beam scenario. This avoids the problem that, due to certain factors, the co-receiving beam pair or the co-transmitting beam pair of a terminal device cannot be maintained, and the network device is unable to know in a timely manner. The network device schedules the terminal device for transmission based on the poor-quality co-receiving beam pair or the co-transmitting beam pair, which results in severe performance loss.

[0007] The first aspect of the present application provides a method for sending information, which is executed by a terminal device. The terminal device may be a device or apparatus with a chip, or a device or apparatus with an integrated circuit, or a chip, chip system, module, or control unit in the aforementioned device or apparatus, and the present application does not limit this. It should be noted that in the present application, when referring to a terminal device, it may refer to the terminal device itself, or to a chip, functional module, or integrated circuit in the terminal device that completes the method provided by the present application, and the present application does not limit this. In the first aspect and its possible implementation, the method is described as being executed by a terminal device. The method includes: a terminal device determines first information; wherein the first information includes at least one of the following: identifiers of one or more available resource groups, identifiers of resources in one or more available resource groups, signal quality of resources in one or more available resource groups, one or more report identifiers, identifiers of resource groups corresponding to one or more report identifiers, identifiers of resources in resource groups corresponding to one or more report identifiers, signal quality of resources in resource groups corresponding to one or more report identifiers, identifiers of one or more unavailable resource groups, identifiers of resources in one or more unavailable resource groups, signal quality of resources in one or more unavailable resource groups, first indication information, second indication information, or third indication information; wherein the first indication information is used to indicate whether one or more resource groups reported by the terminal device are available or to indicate whether resources in one or more resource groups are available, or the first indication information is used to indicate whether the resource group or resources in the resource group currently used by the terminal device are available, the second indication information is used to indicate one or more resource groups reported by the terminal device or to indicate the resource group currently used by the terminal device, and the third indication information is used to indicate whether the signal quality difference between two resources in the resource group indicated by the second indication information is greater than a first threshold; the terminal device sends the first information to the network device. It can be seen from this that the terminal device sends the first information to the network device. This enables terminal devices to proactively and promptly report the signal quality or availability of resource groups (also known as co-receiving or co-transmitting beam pairs). This prevents situations where a terminal device's co-receiving or co-transmitting beam pair cannot be maintained due to certain factors, and the network device is unaware of this. This can lead to network devices scheduling terminal device transmission based on poor-quality co-receiving or co-transmitting beam pairs, resulting in severe performance loss.

[0008] The second aspect of the present application provides an information receiving method, which is performed by a network device. The network device may be a device or apparatus with a chip, or a device or apparatus with an integrated circuit, or a chip, chip system, module, or control unit in the aforementioned device or apparatus, and the present application does not limit this. It should be noted that in the present application, when referring to a network device, it may refer to the network device itself, or to a chip, functional module, or integrated circuit in the network device that completes the method provided in the present application, and the present application does not limit this. In the second aspect and its possible implementation, the method is described as being performed by a network device as an example. The method includes: a network device receives first information from a terminal device; wherein the first information includes at least one of the following: identifiers of one or more available resource groups, identifiers of resources in one or more available resource groups, signal quality of resources in one or more available resource groups, one or more report identifiers, identifiers of resource groups corresponding to one or more report identifiers, identifiers of resources in resource groups corresponding to the one or more report identifiers, signal quality of resources in resource groups corresponding to one or more report identifiers, identifiers of one or more unavailable resource groups, identifiers of resources in one or more unavailable resource groups, signal quality of resources in one or more unavailable resource groups, first indication information, second indication information, or third indication information; wherein the first indication information is used to indicate whether one or more resource groups reported by the terminal device are available or to indicate whether resources in one or more resource groups are available, or the first indication information is used to indicate whether the resource group or resources in the resource group currently used by the terminal device are available, the second indication information is used to indicate one or more resource groups reported by the terminal device or to indicate the resource group currently used by the terminal device, and the third indication information is used to indicate whether the signal quality difference between two resources in the resource group indicated by the second indication information is greater than a first threshold. It can be seen from this that the network device receives the first information sent by the terminal device. This enables terminal devices to proactively and promptly report the signal quality or availability of resource groups (also known as co-receiving or co-transmitting beam pairs). Network devices can promptly obtain the availability of each resource group. This prevents situations where a terminal device's co-receiving or co-transmitting beam pair cannot be maintained due to certain factors, and the network device is unaware of this. This can lead to network devices scheduling terminal device transmission based on poor-quality co-receiving or co-transmitting beam pairs, resulting in severe performance loss.

[0009] Based on the first aspect or the second aspect, in a possible implementation, a resource group includes multiple resources, and the multiple resources are used to determine parameters for simultaneous uplink transmission and / or for determining parameters for simultaneous downlink reception. That is, the resources in a resource group are used to determine the corresponding parameters for simultaneous uplink transmission and / or for determining the corresponding parameters for simultaneous downlink reception. For example, in a multiple transmission and receiving point (mTPR) transmission mode, the resource group includes resources corresponding to beams used when uplink transmission or downlink reception is performed between a terminal device and multiple transmission and receiving points (TRP). In a simultaneous transmission with multi-panel (STxMP) transmission mode, the resource group includes resources corresponding to beams used by multiple antenna panels of a terminal device. Each resource in a resource group corresponds to a beam, and different resources correspond to different beams. A resource group may also be referred to as a beam pair, and the beam pair may be a co-receiving beam pair, a co-receiving beam pair, or a beam pair capable of both co-receiving and co-transmitting. In other words, the first information includes at least one of the following: the identifiers of one or more available beam pairs, the identifiers of the beams in one or more available beam pairs, the signal quality of the beams in one or more available beam pairs, one or more reporting identifiers, the identifiers of the beam pairs corresponding to one or more reporting identifiers, the identifiers of the beams in the beam pairs corresponding to one or more reporting identifiers, the signal quality of the beams in the beam pairs corresponding to one or more reporting identifiers, the identifiers of one or more unavailable beam pairs, the identifiers of the beams in one or more unavailable beam pairs, the signal quality of the beams in one or more unavailable beam pairs, the first indication information, the second indication information, or the third indication information. The first indication information is used to indicate whether the one or more beam pairs reported by the terminal device are available or to indicate whether the beams in the one or more beam pairs are available, or the first indication information is used to indicate whether the beam pair currently used by the terminal device or the beams in the beam pair are available. The second indication information is used to indicate the one or more beam pairs reported by the terminal device or to indicate the beam pair currently used by the terminal device. The third indication information is used to indicate whether the signal quality difference between the two beams in the beam pair indicated by the second indication information is greater than the first threshold. It should be noted that, in the present application, a beam pair can also be represented by multiple transmission configuration indicator (TCI) state identifiers, or by multiple reference signal identifiers.For example, the reference signal can be a synchronization / broadcast signal (synchronization signal / physical broadcast channel block, SS / PBCH block, abbreviated as SSB) or a channel state information reference signal (CSI-RS). In the present application, the identification of the beam can also be replaced by a TCI state identification, or replaced by a representation of a reference signal. Optionally, the reference signal is a reference signal associated with the TCI state for communication between the terminal device and the network device. In the present application, the report identifier can also be replaced by a report configuration identifier (report config ID). In the present application, the resource can be replaced by the description of the reference signal, which is not limited in this application.

[0134] Embodiments of the present application provide an information sending method, an information receiving method, and related devices for enabling a terminal device to send first information to a network device. This enables the terminal device to proactively report the signal quality or availability of a resource group (also referred to as a co-receiving beam pair or a co-transmitting beam pair) in a multi-beam scenario. This avoids the problem where, due to certain factors, the co-receiving beam pair or the co-transmitting beam pair of the terminal device cannot be maintained, and the network device is unable to promptly learn of this. Consequently, the network device schedules the terminal device for transmission based on the poor-quality co-receiving beam pair or the co-transmitting beam pair, which results in severe performance loss.

The wireless communication system involved in the present application also includes but is not limited to: a narrowband Internet of Things system (NB-IoT).

[0140] The communication system to which this application is applicable includes network equipment and terminal equipment. The network equipment and terminal equipment are introduced below.

[0141] The terminal device may be a wireless terminal device capable of receiving network device scheduling information and instruction information. The terminal device may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing device connected to a wireless modem.

[0142] Terminal equipment, also known as user equipment (UE), mobile station (MS), mobile terminal (MT), or customer premise equipment (CPE), is a device that includes wireless communication capabilities (providing voice / data connectivity to users). For example, it can be a handheld device or vehicle-mounted device with wireless connectivity.

Wireless terminals in industrial control can be cameras, robots, or robotic arms. Wireless terminals in smart homes can be televisions, air conditioners, vacuum cleaners, speakers, or set-top boxes.

[0143] It should be noted that the terminal device can be a device or apparatus with a chip, or a device or apparatus with an integrated circuit, or a chip, chip system, module or control unit in the device or apparatus shown above, and this application does not limit it specifically. It should be noted that in this application, when referring to a terminal device, it can refer to the terminal device itself, or it can refer to a chip, functional module or integrated circuit in the terminal device that performs the method provided in this application, and this application does not limit it specifically.

[0144] A network device may be a device in a wireless network. For example, a network device may be a device deployed in a radio access network that provides wireless communication capabilities for terminal devices. For example, a network device may be a radio access network (RAN) node that connects a terminal device to a wireless network. The network device may also be referred to as an access network device, a RAN entity, an access node, a network node, or a communication device.

[0145] Specifically, the network device may be an access network device for a cellular system related to the Third Generation Partnership Project (3GPP). For example, a 4G communication system or a 5G communication system. The network device may also be an access network device in an open access network (O-RAN or ORAN) or a cloud radio access network (CRAN). Alternatively, the network device may be an access network device in a communication system obtained by integrating two or more of the above communication systems.

[0146] The network device includes, but is not limited to, an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., a home evolved NodeB, or a home Node B, HNB), a baseband unit (BBU), an access point (AP) in a wireless fidelity (WIFI) system, a macro base station, a micro base station, a wireless relay node, a donor node, a wireless controller in a CRAN scenario, a wireless backhaul node, a transmission point (TP), or a TRP, and may also be a network device in a 5G mobile communication system. For example, a next generation NodeB (gNB), a TRP, or a TP in an NR system; or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G mobile communication system; or the network device may also be a network node constituting a gNB or a transmission point. For example, a centralized unit (CU), a distributed unit (DU), a centralized unit control plane (CU-CP), a centralized unit user plane (CU-UP), or a radio unit (RU), etc. The CU and DU can be set separately, or can also be included in the same network element, such as a BBU. The RU can be included in a radio frequency device or a radio frequency unit. For example, in a remote radio unit (RRU), an active antenna unit (AAU), or a remote radio head (RRH). Alternatively, the network device can also be a server, a wearable device, a vehicle, or an on-board device, etc. For example, the access network device in the V2X technology can be a road side unit (RSU).

[0147] It should be noted that in different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in an open radio access network (ORAN) system, CU may also be called an open centralized unit (O-CU) or an open CU, DU may also be called an open distributed unit (O-DU), CU-CP may also be called an open centralized unit control plane (O-CU-CP), CU-UP may also be called an open centralized unit user plane (O-CU-UP), and RU may also be called an open radio unit (O-RU). This application does not limit this. Any of the CU, CU-CP, CU-UP, DU and RU in this application may be implemented through a software module, a hardware module, or a combination of a software module and a hardware module.

[0148] Optionally, for network elements in the ORAN system, each network element may implement the protocol layer functions shown in Table 1 below.

[0149] Table 1

[0150] It should be noted that, in the ORAN system, the network device in this application may be one or more network elements in Table 1 above.

[0151] The following describes the architecture of the CU and DU of an access network device. The access network device includes at least one CU and at least one DU. Optionally, the access network device also includes at least one RU.

[0152] The following is an introduction using the example of an access network device including a CU and a DU. The CU has some functions of the core network, and the CU may include a CU-CP and a CU-UP. The CU and the DU may be configured according to the protocol layer functions of the wireless network they implement. For example, the CU is configured to implement the functions of the packet data convergence protocol (PDCP) layer and the protocol layers above it (for example, the RRC layer and / or the SDAP layer). The DU is configured to implement the functions of the protocol layers below the PDCP layer (for example, the RLC layer, the MAC layer, and / or the physical (PHY) layer). For another example, the CU is configured to implement the functions of the protocol layers above the PDCP layer (such as the RRC layer and / or the SDAP layer), and the DU is configured to implement the functions of the PDCP layer and the protocol layers below it (for example, the RLC layer, the MAC layer, and / or the PHY layer, etc.).

[0153] When a CU includes a CU-CP and a CU-UP, the CU-CP is used to implement the control plane functions of the CU, and the CU-UP is used to implement the user plane functions of the CU. For example, when the CU is configured to implement the functions of the PDCP layer, RRC layer, and SDAP layer, the CU-CP is used to implement the RRC layer functions and the control plane functions of the PDCP layer, and the CU-UP is used to implement the SDAP layer functions and the user plane functions of the PDCP layer.

[0154] The CU-CP can interact with network elements in the core network that implement control plane functions. The network elements in the core network that implement control plane functions can be access and mobility function network elements, such as the access and mobility management function (AMF) in the 5G system. The access and mobility function network element is responsible for mobility management in the mobile network, such as location update of terminal devices, registration network of terminal devices, and switching of terminal devices.

[0155] The CU-UP can interact with network elements in the core network that implement user plane functions. Network elements in the core network that implement user plane functions, such as the user plane function (UPF) in the 5G system, are responsible for forwarding and receiving data in terminal devices.

[0156] The above configuration of CU and DU is only an example, and the functions of CU and DU can also be configured as needed. For example, the CU or DU can be configured to have the functions of more protocol layers, or the CU or DU can be configured to have partial processing functions of the protocol layer. For example, some functions of the RLC layer and the functions of the protocol layers above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are set in the DU. For another example, the functions of the CU or DU can be divided according to the service type or other system requirements. For example, according to the delay, the functions whose processing time needs to meet the smaller delay requirement are set in the DU, and the functions that do not need to meet the delay requirement are set in the CU.

[0157] The DU and RU can work together to implement the functions of the PHY layer. A DU can be connected to one or more RUs. The functions of the DU and RU can be configured in various ways according to the design. For example, the DU is configured to implement the baseband function, and the RU is configured to implement the mid-RF function. For another example, the DU is configured to implement the high-layer functions in the PHY layer, and the RU is configured to implement the low-layer functions in the PHY layer or to implement the low-layer functions and the RF functions. The high-layer functions in the physical layer may include a part of the functions of the physical layer, which is closer to the MAC layer, and the low-layer functions in the physical layer may include another part of the functions of the physical layer, which is closer to the mid-RF side.

[0158] It should be noted that the network device can be a device or apparatus with a chip, or a device or apparatus with an integrated circuit, or a chip, chip system, module or control unit in the aforementioned device or apparatus, and this application does not limit this. It should be noted that in this application, when referring to a network device, it can refer to the network device itself, or it can refer to a chip, functional module or integrated circuit in the network device that performs the method provided in this application, and this application does not limit this.

[0159] It should be noted that the concepts of network devices and TRPs are mentioned together in this application. Network devices can be understood as a general term for all devices (including sites) on the network side. For example, multiple TRPs can be collectively referred to as network devices. TRP refers to a transmission node located in a specific physical location. In other words, network devices conceptually include TRPs. That is, network devices can include one TRP or multiple TRPs.

[0160] To facilitate understanding of the technical solutions of the embodiments of the present application, two possible communication systems to which the method provided in the embodiments of the present application is applicable are shown below in conjunction with FIG1 and FIG2 .

[0161] Figure 1 is a schematic diagram of a communication system according to an embodiment of the present application. As shown in Figure 1 , the communication system includes at least one network device and at least one terminal device. For example, network device 111, terminal device 121, and terminal device 122 are shown in Figure 1 . Network device 111 can communicate with terminal device 121 and terminal device 122. The technical solutions of the present application can be implemented between network device 111 and terminal device 121 or terminal device 122.

[0162] Figure 2 is another schematic diagram of a communication system according to an embodiment of the present application. As shown in Figure 2, the communication system may include at least two network devices and at least one terminal device. For example, network device 211, network device 212, network device 213, and terminal device 221 are shown in Figure 2. Terminal device 221 may be provided with communication services by multiple network devices. For example, as shown in Figure 2, network device 211 may transmit to terminal device 221, and network device 212 may transmit to terminal device 221. Network device 213 may transmit to terminal device 221. In other words, a terminal device may be provided with communication services by multiple network devices simultaneously. The technical solution of the present application may be implemented between terminal device 221 and network device 211, network device 212, or network device 213.

[0163] In an embodiment of the present application, the terminal device may adopt the mTRP transmission mode or the STxMP transmission mode. The mTRP transmission mode refers to the terminal device transmitting with multiple TRPs, each TRP corresponds to a beam, and the terminal device transmits with the TRP through the beam. In the communication protocol, TRP may be transparent to the terminal device. For the terminal device, the network device indicates that multiple beams are used for communication. Multiple beams can be used to receive downlink signals at the same time, or they can be used to receive downlink signals in turn. The STxMP transmission mode refers to the terminal device transmitting with the network device through two antenna panels, each antenna panel corresponds to a beam, and the terminal device transmits with the TRP through the beam. For the terminal device, the network device indicates that multiple beams are used for communication. Multiple beams can be used to send uplink signals at the same time, or they can be used to send uplink signals in turn.

[0164] The following uses the mTRP transmission mode as an example to introduce two possible scenarios in which this application is applicable.

[0165] Figure 3A is a schematic diagram of a scenario for the mTRP transmission mode according to an embodiment of the present application. As shown in Figure 3A , both TRPs correspond to the same serving cell, i.e., one cell includes two network devices or two TRPs. These two network devices or two TRPs can be combined to achieve joint transmission. As shown in Figure 3A , terminal device 303 can transmit with TRP 301 via beam 1 and with TRP 302 via beam 2.

[0166] Figure 3B illustrates another scenario for the mTRP transmission mode in an embodiment of the present application. As shown in Figure 3B , two TRPs correspond to different cells, meaning the TRPs of the two cells are combined for joint transmission. As shown in Figure 3B , TRP3-1 corresponds to cell 1, and TRP3-2 corresponds to cell 2. The terminal device transmits with TRP1 via beam 1 and transmits with TRP3-2 via beam 2.

[0167] In order to facilitate understanding of the technical solution of this application, some technical terms involved in this application are introduced below.

[0168] 1. Beam: A beam is a communication resource. It can be wide, narrow, or any other type of beam. Beam formation can be achieved through beamforming or other techniques. Beamforming techniques include digital beamforming, analog beamforming, and hybrid digital / analog beamforming. Different beams can be considered different resources.

[0169] In the NR protocol, beam can be called spatial domain filter, spatial filter, spatial domain parameter, spatial parameter, spatial parameter, spatial domain setting, spatial setting, quasi-colocation (QCL) information, QCL assumption, or QCL indication, etc. The beam can be indicated by the TCI-state parameter or by the spatial relation parameter. Therefore, in this application, beam can be replaced by spatial filter, spatial filter, spatial parameter, spatial parameter, spatial setting, spatial setting, QCL information, QCL assumption, QCL indication, TCI-state (including uplink TCI-state, downlink TCI-state), or spatial relationship, etc. The above terms are also equivalent to each other. Beam can also be replaced by other terms representing beams, which are not limited in this application.

[0170] A beam used to transmit a signal may be referred to as a transmission beam (Tx beam), a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter, a spatial transmission parameter, a spatial domain transmission setting, or a spatial transmission setting. The downlink transmit beam may be indicated by a TCI-state.

[0171] A beam used to receive a signal may be referred to as a reception beam (Rx beam), a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter, a spatial reception parameter, a spatial domain reception setting, or a spatial reception setting. An uplink transmit beam may be indicated by any of a spatial relationship, an uplink TCI-state, and a sounding reference signal (SRS) resource (indicating a transmit beam using the SRS). Therefore, an uplink beam may also be replaced by an SRS resource.

[0172] The transmit beam may refer to the distribution of signal strength in different directions in space after the signal is transmitted by the antenna, and the receive beam may refer to the distribution of signal strength in different directions in space of the wireless signal received from the antenna.

[0173] Furthermore, the beam may be a wide beam, a narrow beam, or other types of beams. The beam forming technology may be beamforming technology or other technologies. The beamforming technology may specifically be digital beamforming technology, analog beamforming technology, hybrid digital beamforming technology, or hybrid analog beamforming technology.

[0174] Beams generally correspond to resources. For example, when performing beam measurement, network equipment uses different resources to measure different beams. The terminal device then provides feedback on the measured resource quality, allowing the network equipment to determine the quality of the corresponding beam. During data transmission, beam information is also indicated by its corresponding resource. For example, the network equipment uses the TCI field in the DCI to indicate the terminal device's physical downlink shared channel (PDSCH) beam information.

[0175] In one possible implementation, multiple beams with identical or similar communication characteristics are considered a single beam. A beam can include one or more antenna ports for transmitting data channels, control channels, and sounding signals. The one or more antenna ports that form a beam can also be considered an antenna port set.

[0176] 2. QCL: Quasi-colocation relationship is used to indicate that multiple resources have one or more identical or similar communication characteristics. For multiple resources with a quasi-colocation relationship, the same or similar communication configuration can be adopted. For example, if two antenna ports have a quasi-colocation relationship, the large-scale characteristics of the channel for transmitting a symbol on one port can be inferred from the large-scale characteristics of the channel for transmitting a symbol on the other port. Large-scale characteristics may include: delay spread, average delay, Doppler spread, Doppler shift, average gain, receiving parameters, terminal device receiving beam number, transmit / receive channel correlation, receive arrival angle, receiver antenna spatial correlation, main angle of arrival (AoA), average arrival angle, AoA spread, etc. Specifically, the colocation indication is used to indicate whether at least two groups of antenna ports have a colocation relationship, including: the colocation indication is used to indicate whether the channel state information reference signals sent by at least two groups of antenna ports come from the same transmission point, or the colocation indication is used to indicate whether the channel state information reference signals sent by at least two groups of antenna ports come from the same beam group.

[0177] 3. TCI: It can also be called TCI state (TCI-state). In uplink and downlink transmission, the correct beam needs to be used between the network device and the terminal device to achieve correct transmission. In downlink transmission, the network device needs to indicate to the terminal device the downlink transmission beam it uses. The terminal device can determine the appropriate receiving beam based on the downlink transmission beam, and the receiving beam is used to receive information from the network device. In uplink transmission, the network device also needs to indicate to the terminal device which uplink transmission beam the terminal device uses to send information to the network device. The network device can determine the uplink transmission beam with better signal quality for the terminal device. Both the uplink transmission beam and the downlink transmission beam can be indicated by the corresponding TCI state. Specifically, the downlink transmission beam can be indicated by the downlink TCI state, and the uplink transmission beam can be indicated by the uplink TCI state.

[0178] In the 3GPP protocol, the network device can indicate the TCI state to the terminal device through the TCI field in the downlink control information (DCI). The size of the TCI field is 3 bits and can be specifically expressed as 8 different field values ​​(codepoints). Each field value of the TCI field can be associated with an index of a TCI state. The index of the TCI state can uniquely identify a TCI state, and the TCI state can be a downlink TCI state or an uplink TCI state. Each field value of the TCI field can also be associated with two TCI state indexes, and the two TCI state indexes can uniquely identify two TCI states, and the two TCI states can include a downlink TCI state and an uplink TCI state.

[0179] The downlink TCI state includes several parameters that allow the terminal device to determine the relevant information of the downlink transmit beam and thus determine the appropriate receive beam to receive information from the network device. The TCI state is configured by the network device for each terminal device. The structure of the downlink TCI state is as follows:

[0180] Each TCI state includes its own index (tci-StateId) and two quasi-colocation information (QCL-info). Each QCL-info includes a reference signal resource, which is used to indicate that the downlink transmission of the TCI state should use the same downlink timing, frequency offset or receiving beam as the reference signal resource. It is specifically determined by the type of the QCL-info. The QCL type can have four values ​​{typeA, typeB, typeC, typeD}. When the QCL type is typeA, typeB and typeC, the downlink transmission should be carried out using the same downlink timing and frequency offset as the reference signal resource. When the QCL type is typeD, the downlink transmission should be carried out using the same receiving beam as the reference signal resource. Of the two QCL-infos mentioned above, one is of typeD and the other is of typeA or typeB or typeC. The terminal device can determine which receiving beam to use to receive the corresponding downlink transmission through the QCL-info of typeD. The specific execution steps are as follows:

[0181] The network device indicates a downlink TCI state to the terminal device through DCI. The terminal device determines the reference signal resource in the QCL information of type D in the downlink TCI state. The terminal device uses the receiving beam of the reference signal resource as the receiving beam used for downlink transmission. It should be noted that the receiving beam of the reference signal resource is obtained by the terminal device in advance through the beam management process. Through the beam management process, the terminal device can determine which receiving beam is best to receive the reference signal resource, and use the receiving beam as the receiving beam of the reference signal resource.

[0182] The uplink TCI state includes a reference signal resource, which is used to indicate that the uplink transmission using this TCI state should use the same uplink transmit beam as the reference signal resource. The terminal device can determine which transmit beam to use for uplink transmission through this reference signal resource. In the uplink TCI state, the reference signal resource is not included in the QCL-info, and the QCL type is not distinguished, because there is no need to refer to the uplink timing and frequency offset information, only the uplink transmit beam. The structure of the uplink TCI state is shown below:

[0183] The specific steps are as follows:

[0184] The network device indicates a certain uplink TCI state to the terminal device through the DCI. The terminal device determines the reference signal resource in the uplink TCI state. The terminal device uses the transmit beam of the reference signal resource as the transmit beam used by the terminal device for uplink transmission. It should be noted that the transmit beam of the reference signal resource is obtained by the terminal device in advance through the beam management process.

[0185] The following describes the configuration, activation and indication of TCI status.

[0186] TCI-state configuration: The network device configures multiple TCI-states to the terminal device through RRC signaling. These TCI-states all include a QCL-Info of type D. The network device can also configure TCI-states that do not include QCL-info of type D. However, these TCI-states are not used to indicate data transmission beams and are not further explained here.

[0187] TCI-state activation: After a network device is configured with multiple TCI-states, it must activate eight of them through MAC-CE. These eight TCI-states correspond one-to-one to the eight values ​​of the TCI field in the DCI. That is, the MAC-CE determines which TCI-states correspond to the eight values ​​of the TCI field in the DCI.

[0188] TCI state indication: The network device indicates a specific TCI-state through the TCI field in the DCI. For example, the value of the TCI field in the DCI sent by the network device to the terminal device is 000, indicating that the data transmission beam adopts the TCI state corresponding to 000. The reference signal contained in the QCL-Info of type D in this TCI state is the channel state information-reference signal (CSI-RS) with an index of #1, indicating that the beam used for data transmission is the same as the receiving beam corresponding to the CSI-RS with an index of #1. The receiving beam corresponding to the CSI-RS with an index of #1 can be determined through the beam measurement process and is known to the terminal device. Therefore, through the specific value of the TCI field, the terminal device can determine the beam corresponding to the data transmission beam, and thus adopt the corresponding beam to send or receive data.

[0189] It should be noted that the three descriptions of TCI state, TCI-state and TCI state in this article can be used interchangeably.

[0190] The following describes the beam measurement reporting mechanism in mTRP transmission mode.

[0191] The network device can configure two resource sets (also called reference signal resource sets) for the terminal device, each resource set includes one or more resources, one resource corresponds to one beam, and different resources correspond to different beams. Each resource set corresponds to a TRP. It can be seen that the resource set is used to measure the signal quality of the beam used for transmission between the terminal device and the TRP corresponding to the resource set. The network device can configure the terminal device to report the signal quality of the beams in K beam pairs. Specifically, the terminal device reports the signal quality of the beams in K beam pairs to the network device, and each beam pair includes the beams corresponding to each TRP in the two TRPs. The beam pair can be a co-receiving beam pair, a co-transmitting beam pair, or a beam pair that can both receive and transmit at the same time.

[0192] Specifically in the communication protocol, the network device can associate two resource sets (resource set 1 and resource set 2). The terminal device can report one or more resource groups (also called beam pairs) and the corresponding signal quality. Each resource group includes two resources, one of which is from resource set 1 and the other is from resource set 2. Each resource corresponds to a reference signal, so the terminal device measures the resource to obtain the reference signal received power (RSRP) of the resource, which can be understood as the terminal device measuring the reference signal corresponding to the resource to obtain the RSRP of the reference signal. Here we call it the RSRP of the resource. As shown in Table 2, Table 2 shows the four resource groups reported by the terminal device. As shown in Table 3, the four resource groups reported by the terminal device and the RSRP of the resources in each resource group are shown. Among the resource groups reported by the terminal device, the RSRP of the first resource in the resource group that is ranked first by default is the largest.

[0193] Table 2

[0194] Table 3

[0195] Taking into account the beam measurement reporting mechanism of the STxMP transmission mode, the reporting scheme in the STxMP transmission mode is based on the mTRP transmission mode. When configuring measurement reporting resources for terminal devices, the network device adds an explicit signaling instruction to instruct the terminal device to report the co-transmit beam pair, the co-receive beam pair, or the beam pair capable of both co-transmit and co-receive. The reporting content and reporting format in the STxMP transmission mode are consistent with those in the mTRP transmission mode.

[0196] R19 intends to support beam management initiated actively or triggered by events by terminal devices, but R19 only considers beam management of a single beam. For example, the terminal device actively reports the measurement results of the quality changes of the current beam, triggering the base station to perform beam management, thereby timely adjusting the beam used between the terminal device and the network device. The current scheme for beam management initiated actively or triggered by events by terminal devices only considers single-beam scenarios. For multi-beam scenarios (including mTRP transmission mode and STxMP transmission mode), how should the terminal device perform beam management to avoid performance loss? For example, the terminal device can report the potentially available resource groups (also called beam pairs) and the corresponding signal quality according to Tables 2 and 3 above. However, when the signal quality of the resources (also called beams) in the resource group (also called beam pair) changes, the terminal device is not required to measure the resources in the resource group and report the signal quality of the resources within a short period of time. The network device schedules the terminal device for transmission based on the resource group with poor quality. This will cause performance problems, and in severe cases, it will cause transmission failure.

[0197] The present application provides a corresponding technical solution for a terminal device to report first information to a network device, thereby enabling the terminal device to actively report the signal quality or availability of a resource group (also referred to as a beam pair, which is a co-receiving beam pair, a co-transmitting beam pair, or a beam capable of both co-receiving and co-transmitting) in a multi-beam scenario. This avoids the problem that, due to certain factors, the co-receiving beam pair or co-transmitting beam pair of the terminal device cannot be maintained, and the network device is unable to know in a timely manner, and the network device schedules the terminal device to transmit based on the poor-quality co-receiving beam pair or co-transmitting beam pair, which will lead to serious performance loss.

[0198] In the present application, a resource group includes multiple resources, and the multiple resources are used to determine the parameters for simultaneous uplink transmission and / or for determining the parameters for simultaneous downlink reception. For example, in the mTRP transmission mode, the resource group includes the resources corresponding to the beams used when the terminal device performs uplink transmission or downlink reception with multiple TRPs. In the STxMP transmission mode, the resource group includes the resources corresponding to the beams used by multiple antenna panels of the terminal device. Each resource in the resource group corresponds to a beam, and different resources correspond to different beams. The resource group can also be called a beam pair, and the beam pair can be a co-receiving beam pair, a co-receiving beam pair, or a beam pair that can both receive and transmit at the same time. The terminal device can measure each resource in the resource group to obtain the signal quality of each resource. That is, the terminal device can measure each beam in the beam pair to obtain the signal quality of each beam. This makes it easier for the terminal device to report the signal quality of one or more resource groups and the corresponding resources to the network device. The network device can instruct the terminal device to use one of the one or more resource groups and communicate with the network device through the resource group (or beam pair). The following embodiments mainly use an example in which a resource group includes two resources.

[0199] In this application, the resource group can be replaced by the description of beam pair or other names, and the resource can be replaced by the description of beam, reference signal, or other names, which are not limited in this application. The beam pair can be represented by multiple TCI state identifiers or by multiple reference signal identifiers, which are not limited in this application. For example, the reference signal is SSB or CSI-RS. The identification of the beam can also be replaced by the identification of the TCI state, or by the representation of the reference signal. Optionally, the reference signal is a reference signal associated with the TCI state for communication between the terminal device and the network device. In this application, the report identifier can also be replaced by a report configuration identifier, or other names, which are not limited in this application.

[0200] The technical solution of this application is introduced below in conjunction with specific embodiments.

[0201] FIG4 is a schematic diagram of an embodiment of the information sending method and information receiving method of the present application. Referring to FIG4 , the method includes:

[0202] 401. The terminal device determines first information.

[0203] Specifically, the terminal device is in the mTRP transmission mode or the STxMP transmission mode. For one or more resource groups reported by the terminal device, the terminal device can measure the signal quality of resources in the one or more resource groups. Thus, the terminal device can determine whether each resource group in the one or more resource groups is available and determine the first information.

[0204] The first information includes at least one of the following: identifiers of one or more available resource groups, identifiers of resources in one or more available resource groups, signal quality of resources in one or more available resource groups, one or more reporting identifiers, identifiers of resource groups corresponding to one or more reporting identifiers, identifiers of resources in resource groups corresponding to one or more reporting identifiers, signal quality of resources in resource groups corresponding to one or more reporting identifiers, identifiers of one or more unavailable resource groups, identifiers of resources in one or more unavailable resource groups, signal quality of resources in one or more unavailable resource groups, first indication information, second indication information, or third indication information. The first indication information is used to indicate whether one or more resource groups reported by the terminal device are available or to indicate whether the resources in the one or more resource groups are available, or the first indication information is used to indicate whether the resource group currently used by the terminal device or the resources in the resource group are available. The second indication information is used to indicate one or more resource groups reported by the terminal device or to indicate the resource group currently used by the terminal device. The third indication information is used to indicate whether the signal quality difference between two resources in the resource group indicated by the second indication information is greater than a first threshold.

[0205] In other words, the first information includes at least one of the following: the identifiers of one or more available beam pairs, the identifiers of the beams in one or more available beam pairs, the signal quality of the beams in one or more available beam pairs, one or more reporting identifiers, the identifiers of the beam pairs corresponding to one or more reporting identifiers, the identifiers of the beams in the beam pairs corresponding to one or more reporting identifiers, the signal quality of the beams in the beam pairs corresponding to one or more reporting identifiers, the identifiers of one or more unavailable beam pairs, the identifiers of the beams in one or more unavailable beam pairs, the signal quality of the beams in one or more unavailable beam pairs, the first indication information, the second indication information, or the third indication information. The first indication information is used to indicate whether the one or more beam pairs reported by the terminal device are available or to indicate whether the beams in the one or more beam pairs are available, or the first indication information is used to indicate whether the beam pair currently used by the terminal device or the beams in the beam pair are available. The second indication information is used to indicate the one or more beam pairs reported by the terminal device or to indicate the beam pair currently used by the terminal device. The third indication information is used to indicate whether the signal quality difference between the two beams in the beam pair indicated by the second indication information is greater than the first threshold. The following text mainly introduces the first information using resource groups and resources as an example.

[0206] Optionally, the signal quality may include RSRP, or reference signal received quality (RSRQ), or reference signal to interference and noise power ratio (SINR).

[0207] It should be noted that, optionally, each of the one or more report identifiers may correspond to one or more resource groups. Specifically, the network device may determine a report configuration for the terminal device, and the report configuration includes a report identifier, and the report configuration is associated with the resources in the one or more resource groups. The terminal device may report the signal quality of the resources in the one or more resource groups to the network device according to the report configuration. It can be seen that the terminal device may indicate the one or more resource groups targeted by one or more report identifiers, and report whether the one or more resource groups are available. In one possible implementation, the report configuration may further include a reporting condition. In one possible implementation, the report configuration may also be associated with a first resource, and the first resource is used for the terminal device to report the first information.

[0208] Optionally, a resource group includes multiple resources, that is, a resource group includes multiple resources, each of the multiple resources belongs to a resource set, and different resources belong to different resource sets. For example, each resource group includes two resources, one of which belongs to the first resource set and the other belongs to the second resource set.

[0209] Optionally, the identifier of a resource in the one or more available resource groups may be the identifier of the resource in the resource set to which the resource belongs, or the identifier of the resource. The identifier of a resource in the resource group corresponding to the one or more report identifiers may be the identifier of the resource in the resource set to which the resource belongs, or the identifier of the resource. The identifier of a resource in the one or more unavailable resource groups may be the identifier of the resource in the resource set to which the resource belongs, or the identifier of the resource.

[0210] The following describes some possible examples of the content contained in the first information. This application is still applicable to other possible implementations, and this application does not limit them specifically.

[0211] In one possible implementation, the first information includes first indication information. For example, as shown in Table 4, the terminal device reported four resource groups, namely resource group 1 to resource group 4. The terminal device measures the resources in resource group 1 to resource group 4 again, and the terminal device determines that Resource#62 is unavailable or the signal quality of Resource#62 is poor, and the signal quality corresponding to Resource#63, Resource#66, Resource#67 and Resource#68 is good. Therefore, the first indication information can be "0001", and the first bit "0" in the first indication information is used to indicate that resource group 1 is unavailable, the second bit "0" is used to indicate that resource group 2 is unavailable, the third bit "0" is used to indicate that resource group 3 is unavailable, and the fourth bit "1" is used to indicate that resource group 4 is unavailable.

[0212] Table 4

[0213] It should be noted that, in the example shown in Table 4 above, one bit in the first indication information corresponds to a resource group, and the bit is used to indicate whether the resource group corresponding to the bit is available. Of course, in actual applications, multiple bits in the first indication information may correspond to one resource group, and the multiple bits are used to indicate whether the resource groups corresponding to the multiple bits are available. This application does not limit this. Furthermore, the example shown in Table 4 above is only one implementation method. In actual applications, when the value of a bit of the first indication information is 1, it indicates that the resource group corresponding to the bit is unavailable; when the value of a bit of the first indication information is 0, it indicates that the resource group corresponding to the bit is available. This application does not limit this.

[0214] In this implementation, optionally, the first information also includes at least one of the following: identifiers of one or more available resource groups, identifiers of resources in one or more available resource groups, signal quality of resources in one or more available resource groups, identifiers of one or more unavailable resource groups, identifiers of resources in one or more unavailable resource groups, and signal quality of resources in one or more unavailable resource groups. For example, the first information includes first indication information, identifiers of one or more available resource groups, and signal quality of resources in one or more available resource groups. For another example, the first information includes first indication information, identifiers of resources in one or more available resource groups, and signal quality of resources in one or more available resource groups. For another example, the first information includes first indication information, identifiers of one or more unavailable resource groups, and signal quality of resources in one or more unavailable resource groups. For another example, the first information includes first indication information, identifiers of one or more unavailable resource groups, and signal quality of resources in one or more unavailable resource groups. For another example, the first information includes first indication information, identifiers of resources in one or more unavailable resource groups, and signal quality of resources in one or more unavailable resource groups.

[0215] In another possible implementation manner, the first information includes: identifiers of one or more available resource groups and signal qualities of resources in the one or more available resource groups.

[0216] In another possible implementation, the first information includes: an identifier of a resource in one or more available resource groups and a signal quality of the resource in the one or more available resource groups. Optionally, the identifier of a resource in the one or more available resource groups may be an identifier of the resource in a resource set to which the resource belongs, or an identifier of the resource.

[0217] In another possible implementation, the first information includes: one or more reporting identifiers, identifiers of resource groups corresponding to the one or more reporting identifiers, and signal qualities of resources in the resource groups corresponding to the one or more reporting identifiers.

[0218] In another possible implementation, the first information includes: one or more reporting identifiers, identifiers of resources in the resource group corresponding to the one or more reporting identifiers, and signal quality of the resources in the resource group corresponding to the one or more reporting identifiers. Optionally, the identifier of the resource in the resource group corresponding to the one or more reporting identifiers may be an identifier of the resource in the resource set to which the resource belongs, or an identifier of the resource itself.

[0219] In another possible implementation manner, the first information includes: identifiers of one or more unavailable resource groups, and signal qualities of resources in the one or more unavailable resource groups.

[0220] In another possible implementation, the first information includes: an identifier of a resource in one or more unavailable resource groups and a signal quality of the resource in one or more unavailable resource groups. Optionally, the identifier of the resource in the one or more unavailable resource groups may be an identifier of the resource in the resource set to which the resource belongs, or an identifier of the resource. It should be noted that, optionally, the identifier of the resource is a global identifier of the resource, which can be specifically understood as a unique identifier of the resource in the cell in the cell configuration. Accordingly, the resource set is a resource set for measurement, one or more resources are configured in a resource set, and the network device configures or instructs the terminal device to measure the resources in the resource set.

[0221] In another possible implementation, the first information includes: second indication information and third indication information. For example, the terminal device has reported four resource groups, namely resource group 1 to resource group 4. The second indication information indicates resource group 1 and resource group 2. The third indication information indicates that the signal quality difference between the two resources in resource group 1 is greater than the first threshold, and indicates that the signal quality difference between the two resources in resource group 2 is not greater than the first threshold. For another example, the second indication information indicates resource group 1 currently used by the terminal device, and the third indication information indicates that the signal quality difference between the two resources in resource group 1 is greater than the first threshold.

[0222] It should be noted that the first threshold may be pre-configured by the network device through high-layer signaling or MAC CE. Optionally, the first threshold may be determined in combination with at least one of the channel environment of the terminal device communication, the service type of the terminal device, the quality of service (QoS) of the terminal device, and the mobility of the terminal device.

[0223] 402. The terminal device sends first information to the network device. Correspondingly, the network device receives the first information from the terminal device.

[0224] Optionally, when a first condition is met, the terminal device sends the first information to the network device. The first condition includes at least one of the following:

[0225] 1. In a resource group reported by the terminal device, a signal quality difference between a signal quality of a resource in a first resource set and a signal quality of a resource in a second resource set is greater than a first threshold.

[0226] In other words, in a resource group reported by the terminal device, the signal quality difference between the signal quality of the resources belonging to the first resource set and the signal quality of the resources belonging to the second resource set is greater than or equal to the first threshold. In other words, a resource group reported by the terminal device includes a first resource and a second resource, and the signal quality difference between the signal quality of the first resource and the signal quality of the second resource is greater than the first threshold. In other words, a resource group reported by the terminal device includes a first resource and a second resource, and the signal quality difference between the signal quality of the first resource and the signal quality of the second resource is greater than or equal to the first threshold. Optionally, the first resource belongs to the first resource set, and the second resource belongs to the second resource set. That is, there is a resource in at least one resource group in the resource group reported by the terminal device that meets the following conditions: the signal quality difference between the signal quality of the resources belonging to the first resource set and the signal quality of the resources belonging to the second resource set is greater than the first threshold.

[0227] In this implementation, the terminal device has reported one or more resource groups, each resource group includes two resources, one of which belongs to the first resource set and the other belongs to the second resource set. When the signal quality difference between the signal quality of the resources in the first resource set and the signal quality of the resources in the second resource set in a resource group is greater than the first threshold, the terminal device can send the first information to the network device. For example, as shown in Figure 5, a resource group reported by the terminal device includes two resources, one of which corresponds to beam 64 and the other corresponds to beam 65. If the terminal device determines that the signal quality difference between the signal quality of beam 64 and the signal quality of beam 65 is greater than the first threshold, then the terminal device can determine that the resource group (which can also be referred to as a beam pair consisting of beam 64 and beam 65) is unavailable.

[0228] In this implementation, optionally, the first indication information indicates that the resource group is unavailable. Optionally, the identifiers of the one or more unavailable resource groups in the first information include the identifier of the resource group. The identifiers of the resources in the one or more unavailable resource groups in the first information include the identifiers of the resources in the resource group. The second indication information in the first information indicates the resource group, and the third indication information indicates that the signal quality difference between two resources in the resource group is greater than a first threshold.

[0229] 2. The signal quality of one or more resources in a resource group reported by the terminal device is less than a second threshold.

[0230] In other words, the signal quality of one or more resources contained in a resource group reported by the terminal device is less than or equal to the second threshold. That is, among the resource groups reported by the terminal device, there is a resource in at least one resource group that meets the following conditions: the signal quality of one or more resources contained in each resource group in the at least one resource group is less than the second threshold. In this implementation, the terminal device has reported one or more resource groups, and when the signal quality of one or more resources in a resource group is less than the second threshold, the terminal device can send the first information to the network device. For example, as shown in Figure 5, a resource group reported by the terminal device includes two resources, one of which corresponds to beam 64 and the other corresponds to beam 65. If the terminal device determines that the signal quality of beam 64 is less than the second threshold, then the terminal device can determine that the resource group (which can also be referred to as a beam pair consisting of beam 64 and beam 65) is unavailable.

[0231] It should be noted that the second threshold may be pre-configured by the network device through high-layer signaling or MAC CE. Optionally, the first threshold may be determined in combination with at least one of the channel environment of the terminal device communication, the service type of the terminal device, the QoS of the terminal device, and the mobility of the terminal device.

[0232] In this implementation, optionally, the first indication information indicates that the resource group is unavailable. Optionally, the identifiers of the one or more unavailable resource groups in the first information include the identifier of the resource group. The identifiers of the resources in the one or more unavailable resource groups in the first information include the identifiers of the resources in the resource group. The second indication information in the first information indicates the resource group, and the third indication information indicates that the signal quality difference between two resources in the resource group is greater than a first threshold.

[0233] 3. In the resource group currently used by the terminal device, a signal quality difference between a signal quality of resources belonging to the first resource set and a signal quality of resources belonging to the second resource set is greater than a first threshold.

[0234] In other words, in the resource group currently used by the terminal device, the signal quality difference between the signal quality of the resources belonging to the first resource set and the signal quality of the resources belonging to the second resource set is greater than or equal to the first threshold. In other words, the resource group currently used by the terminal device includes the third resource and the fourth resource, and the signal quality difference between the signal quality of the third resource and the signal quality of the fourth resource is greater than the first threshold. In other words, the resource group currently used by the terminal device includes the third resource and the fourth resource, and the signal quality difference between the signal quality of the third resource and the signal quality of the fourth resource is greater than or equal to the first threshold. Optionally, the third resource belongs to the first resource set and the fourth resource belongs to the second resource set. For example, as shown in Figure 5, the resource group currently used by the terminal device includes two resources, one of which belongs to the first resource set and the other belongs to the second resource set. One of the two resources corresponds to beam 1 and the other corresponds to beam 128. If the terminal device determines that the signal quality difference between the signal quality of beam 1 and the signal quality of beam 128 is greater than the first threshold, then the terminal device can determine that the resource group (which can also be referred to as a beam pair consisting of beam 1 and beam 128) is unavailable.

[0235] In this implementation, optionally, the first indication information indicates that the resource group currently used by the terminal device is unavailable. Optionally, the identifiers of the one or more unavailable resource groups in the above-mentioned first information include the identifier of the resource group currently used by the terminal device. The identifiers of the resources in the one or more unavailable resource groups in the above-mentioned first information include the identifier of the resources in the resource group currently used by the terminal device. The second indication information in the above-mentioned first information indicates the resource group currently used by the terminal device, and the third indication information indicates that the signal quality difference between two resources in the resource group currently used by the terminal device is greater than the first threshold.

[0236] 4. The signal quality of one or more resources in the resource group currently used by the terminal device is less than a second threshold.

[0237] In other words, the signal quality of one or more resources in the resource group currently used by the terminal device is less than or equal to the second threshold.

[0238] For details about the second threshold, please refer to the above description and will not be repeated here.

[0239] In this implementation, optionally, the first indication information indicates that the resource group currently used by the terminal device is unavailable. Optionally, the identifiers of the one or more unavailable resource groups in the above-mentioned first information include the identifier of the resource group currently used by the terminal device. The identifiers of the resources in the one or more unavailable resource groups in the above-mentioned first information include the identifier of the resources in the resource group currently used by the terminal device. The second indication information in the above-mentioned first information indicates the resource group currently used by the terminal device, and the third indication information indicates that the signal quality difference between two resources in the resource group currently used by the terminal device is greater than the first threshold.

[0240] 5. The simultaneous transmission condition and / or simultaneous interpretation condition are not met. The terminal device determines whether the simultaneous transmission condition and / or simultaneous interpretation condition are met according to its implementation.

[0241] For example, failure to meet the simultaneous transmission condition and / or simultaneous interpretation condition includes: insufficient battery power of the terminal device, or battery power of the terminal device is lower than a corresponding threshold.

[0242] 6. In the resource group with the best signal quality among the resource groups reported by the terminal device, the signal quality difference between the signal quality of the resources in the first resource set and the signal quality of the resources in the second resource set is greater than the first threshold. Or,

[0243] In other words, in the resource group with the best signal quality reported by the terminal device, the signal quality difference between the signal quality of the resources belonging to the first resource set and the signal quality of the resources belonging to the second resource set is greater than or equal to the first threshold. In other words, the resource group with the best signal quality reported by the terminal device includes the fifth resource and the sixth resource, and the signal quality difference between the signal quality of the fifth resource and the signal quality of the sixth resource is greater than the first threshold. In other words, the resource group with the best signal quality reported by the terminal device includes the fifth resource and the sixth resource, and the signal quality difference between the signal quality of the fifth resource and the signal quality of the sixth resource is greater than or equal to the first threshold. Optionally, the fifth resource belongs to the first resource set, and the sixth resource belongs to the second resource set. Optionally, the resource group with the best signal quality is the resource group whose signal quality is greater than the corresponding threshold in the resource group reported by the terminal device. That is, the resources in each resource group whose signal quality is greater than the corresponding threshold in the resource group reported by the terminal device meet the following conditions: the signal quality difference between the signal quality of the resources belonging to the first resource set and the signal quality of the resources belonging to the second resource set is greater than the first threshold. For example, as shown in Figure 5, the resource group with the best signal quality reported by the terminal device includes two resources, one of which belongs to the first resource set and the other belongs to the second resource set. One of the two resources corresponds to beam 64, and the other corresponds to beam 65. If the terminal device determines that the signal quality difference between beam 64 and beam 65 is greater than a first threshold, the terminal device may determine that the resource group (also referred to as the beam pair consisting of beam 64 and beam 65) is unavailable.

[0244] In this implementation, optionally, the first indication information indicates that the resource group with the best signal quality is unavailable. Optionally, the identifiers of the one or more unavailable resource groups in the first information include the identifier of the resource group with the best signal quality. The identifiers of the resources in the one or more unavailable resource groups in the first information include the identifiers of the resources in the resource group with the best signal quality. The second indication information in the first information indicates the resource group with the best signal quality, and the third indication information indicates that the signal quality difference between two resources in the resource group with the best signal quality is greater than a first threshold.

[0245] Regarding the first threshold, please refer to the aforementioned introduction and will not be repeated here.

[0246] 7. Among the resource groups reported by the terminal device and having the best signal quality, there are one or more resources whose signal quality is lower than a second threshold.

[0247] In other words, the signal quality of one or more resources in the resource group with the best signal quality among the resource groups reported by the terminal device is less than or equal to the second threshold. Optionally, the resource group with the best signal quality is the resource group with a signal quality greater than the corresponding threshold among the resource groups reported by the terminal device. That is, the resources in each resource group with a signal quality greater than the corresponding threshold among the resource groups reported by the terminal device meet the following conditions: the signal quality of one or more resources in the resource group is less than the second threshold. For the second threshold, please refer to the aforementioned related introduction and will not be repeated here.

[0248] In this implementation, optionally, the first indication information indicates that the resource group with the best signal quality is unavailable. Optionally, the identifiers of the one or more unavailable resource groups in the first information include the identifier of the resource group with the best signal quality. The identifiers of the resources in the one or more unavailable resource groups in the first information include the identifiers of the resources in the resource group with the best signal quality. The second indication information in the first information indicates the resource group with the best signal quality, and the third indication information indicates that the signal quality difference between two resources in the resource group with the best signal quality is greater than a first threshold.

[0249] It should be noted that future communication protocols may specify that the first condition may include one of the above-mentioned conditions. Alternatively, future communication protocols may specify that the first condition may include multiple conditions shown above, and when one or more of the multiple conditions are met, the terminal device may report the first information, thereby triggering the terminal device to proactively report the first information.

[0250] Optionally, when the terminal device is in mTRP transmission mode or STxMP transmission mode and the first condition is met, the terminal device sends the first information to the network device.

[0251] It should be noted that the content included in the first information can be sent through the first information or through different information, and this application does not limit this. In other words, the content included in the first information can be reported together or separately, and this application does not limit this.

[0252] Optionally, the first information is carried in MAC CE or UCI.

[0253] Optionally, the first information is sent via a first resource.

[0254] In one possible implementation, a first resource is associated with multiple specific resource sets, and the first resource is used to report whether one or more resource groups or resources in one or more resource groups consisting of resources in multiple specific resource sets are available. In other words, the one or more available resource groups, the resource groups corresponding to the one or more report identifiers, the one or more unavailable resource groups, the one or more resource groups, and / or the resource group currently used by the terminal device belong to one or more resource groups consisting of resources in the multiple specific resource sets. The resources in the one or more available resource groups, the resources in the resource groups corresponding to the one or more report identifiers, the resources in the one or more unavailable resource groups, the resources in the one or more resource groups, and / or the resources in the resource group currently used by the terminal device belong to one or more resource groups consisting of resources in the multiple specific resource sets. That is, what the terminal device reports through the first information is the availability of one or more resource groups consisting of resources in multiple specific resource sets, or the availability of resources in one or more resource groups consisting of resources in multiple specific resource sets.

[0255] The one or more resource groups, one or more available resource groups, and one or more unavailable resource groups in the first information described above all belong to the multiple specific resource sets. Therefore, it can be seen that the first resource is limited to reporting the availability of one or more resource groups consisting of resources in the multiple specific resource sets. For other resource groups, the terminal device cannot use the first resource to report availability.

[0256] Optionally, each resource group in one or more resource groups composed of resources in multiple specific resource sets includes multiple resources, each resource comes from a specific resource set, and different resources come from different specific resource sets. For example, multiple specific resource sets include a first resource set and a second resource set, and each resource group in one or more resource groups composed of resources in multiple specific resource sets includes two resources, one of which comes from the first resource set and the other comes from the second resource set. The resources that can be included in different resource groups can be partially the same or completely different. For example, the one or more resource groups include two resource groups, namely resource group 1 and resource group 2. Resource group 1 includes resource a and resource b, resource a comes from the first resource set, and resource b comes from the second resource set. Resource group 2 includes resource a and resource c, resource a comes from the first resource set, and resource c comes from the second resource set.

[0257] In another possible implementation, the first resource is associated with one or more specific reporting identifiers, and the first resource is used to report whether the one or more resource groups corresponding to the one or more specific reporting identifiers or the resources in the one or more resource groups are available. In other words, the one or more available resource groups, the resource groups corresponding to the one or more reporting identifiers, the one or more unavailable resource groups, the one or more resource groups, and / or the resource group currently used by the terminal device belong to the one or more resource groups corresponding to the one or more specific reporting identifiers; the resources in the one or more available resource groups, the resources in the resource groups corresponding to the one or more reporting identifiers, the resources in the one or more unavailable resource groups, the resources in the one or more resource groups, and / or the resources in the resource group currently used by the terminal device belong to the resources in the one or more resource groups corresponding to the one or more specific reporting identifiers. That is, what the terminal device reports through the first information is the availability of one or more resource groups corresponding to the one or more specific reporting identifiers, or the availability of resources in one or more resource groups corresponding to the one or more specific reporting identifiers.

[0258] The one or more resource groups, one or more available resource groups, and one or more unavailable resource groups in the first information all belong to the one or more resource groups corresponding to the one or more specific reporting identifiers. Therefore, it can be seen that the first resource is limited to reporting whether the one or more resource groups corresponding to the one or more specific reporting identifiers are available. For other resource groups, the terminal device cannot use the first resource to report availability.

[0259] Optionally, the first resource is a PUCCH resource and / or a PUSCH resource.

[0260] Optionally, the PUCCH resource may be a periodic PUCCH resource. The PUSCH resource may be a CG-PUSCH resource, or a pre-configured PUSCH resource, or a PUSCH resource used for data transmission of a terminal device. That is, the first resource may be a resource specially configured for reporting the first information, or it may be a resource used for data transmission of a terminal device, and this application does not limit this. For example, the first resource is a CG PUSCH resource, and the first information may be carried in a MAC CE. For another example, the first resource is a periodic PUCCH resource or a CG PUSCH resource, and the first information may be carried in a UCI. For another example, the first resource is a PUSCH resource used for data transmission of a terminal device, and the first information may be carried in a MAC CE or a UCI.

[0261] It should be noted that when the first condition for the terminal device to report the first information is met, the first resource is a valid resource or an available resource, that is, the terminal device considers the first resource to be a valid resource or an available resource.

[0262] Optionally, the embodiment shown in FIG4 further includes step 401a. Step 401a may be performed before step 401.

[0263] 401a. The network device sends first configuration information to the terminal device. The first configuration information is used to configure the first resource. Correspondingly, the terminal device receives the first configuration information from the network device.

[0264] Optionally, the first configuration information is carried in an RRC message.

[0265] Optionally, the first configuration information also includes fourth indication information. The fourth indication information is used to indicate whether the first resource is used to report whether one or more resource groups are available. Each resource group in the one or more resource groups is used to determine the corresponding parameters for simultaneous uplink transmission or to determine the corresponding parameters for simultaneous downlink reception. In other words, the fourth indication information is used to indicate whether the first resource is used to report whether one or more co-receiving beam pairs are available, and / or, to report whether one or more co-transmitting beam pairs are available. For example, the fourth indication information is used to indicate whether the first resource is used to report whether the beam pair currently used by the terminal device is available. For another example, the fourth indication information is used to indicate whether the first resource is used to report whether the beam pair with the best signal quality reported by the terminal device is available. That is, the first configuration information can explicitly configure the first resource to be used to report whether the co-transmitting beam pair is available, or to report whether the co-receiving beam pair is available.

[0266] Optionally, the fourth indication information may also be carried in other information or sent separately, which is not limited in this application. For example, the fourth indication information is carried in a MAC CE or a DCI.

[0267] Optionally, the embodiment shown in FIG4 further includes step 401b. Step 401b may be performed before step 401.

[0268] 401b. The network device sends second configuration information to the terminal device. The second configuration information is used to configure the reporting conditions for the terminal device to report the first information and / or the reporting format for the terminal device to report the first information. Accordingly, the terminal device receives the second configuration information from the network device.

[0269] Regarding the reporting conditions, please refer to the relevant introduction of the first condition mentioned above, which will not be repeated here. Regarding the reporting format, please refer to the relevant introduction of the content contained in the first information mentioned above, which will not be repeated here. It should be noted that the reporting conditions and reporting format of the first information can also be configured through different information, which is not limited by this application.

[0270] As shown in Figure 6, the network device triggers a report of an event that configures a beam pair for the terminal device. The terminal device then measures the beam pair. When the terminal device determines that a beam pair is unavailable, the terminal device may send a first message to the network device via a MAC CE. This MAC CE may be carried on the terminal device's PUSCH resources used for data transmission. This eliminates the need to configure dedicated resources, saving resources.

[0271] Optionally, the second configuration information is carried in an RRC message.

[0272] Optionally, the second configuration information and the first configuration information in step 401a above may be the same configuration information or different configuration information, which is not specifically limited in this application.

[0273] The following introduces some possible implementation solutions between the terminal device and the network device after the terminal device sends the first information to the network device.

[0274] Implementation 1: Optionally, the embodiment shown in FIG4 further includes step 403. Step 403 may be performed after step 402.

[0275] 403. The terminal device communicates with the network device through the first resource in the currently used resource group.

[0276] In this implementation, after the terminal device reports the first information, the terminal device can fall back to the single TRP transmission mode or the single antenna panel transmission mode during the next scheduling process. The terminal device communicates with the network device through the first resource in the currently used resource group by default. Optionally, the first resource in the currently used resource group can be understood as the resource belonging to the first resource set in the currently used resource group. The above step 403 can also be described as: the terminal device communicates with the network device through the first beam in the currently used beam pair. For example, the beam pair currently used by the terminal device includes beam 64 and beam 65, and beam 64 is the first beam in the beam pair. The terminal device can communicate with TRP1 through beam 64, but not communicate with TRP2.

[0277] It should be noted that step 403 above is merely one implementation method. In actual applications, the terminal device can communicate with the network device via resources with better signal quality in the currently used resource group. In other words, the terminal device can communicate with the network device via the beam with better signal quality in the currently used beam pair, which is not limited in this application. For example, as shown in FIG5 , the beam pair currently used by the terminal device includes beam 64 and beam 65. The signal quality of beam 65 is better than the signal quality of beam 64. The terminal device can communicate with TRP2 via beam 65, but not with TRP1.

[0278] Implementation 2: Optionally, the embodiment shown in FIG4 further includes step 404. Step 404 may be performed after step 402.

[0279] 404. If the terminal device does not receive any instruction from the network device, the terminal device continues to send the first information to the network device.

[0280] For example, if the terminal device does not receive a fallback instruction, a switching instruction, or a response to the first information from the network device, the terminal device may continue to report the first information. Optionally, if the terminal device does not receive any instruction from the network device within a preset time, the terminal device continues to send the first information to the network device.

[0281] Implementation 3: Optionally, the embodiment shown in FIG4 further includes steps 405 to 406. Steps 405 to 406 can be performed after step 402.

[0282] 405. The network device sends a rollback instruction to the terminal device. Correspondingly, the terminal device receives the rollback instruction from the network device.

[0283] The fallback indication is used to instruct the terminal device to fall back to single TRP transmission mode or single antenna panel transmission mode.

[0284] 406. The terminal device communicates with the network device through the first resource in the currently used resource group.

[0285] Step 406 is similar to the aforementioned step 403. For details, please refer to the relevant introduction of the aforementioned step 403, which will not be repeated here.

[0286] Implementation 4: Optionally, the embodiment shown in FIG4 further includes steps 407 to 409. Steps 407 to 409 may be performed after step 402.

[0287] 407. The network device sends a switching instruction to the terminal device. Correspondingly, the terminal device receives the switching instruction from the network device.

[0288] The switching indication is used to indicate the target resource group, or the switching indication is used to instruct the terminal device to switch to the target resource group. In other words, the switching indication is used to indicate the target beam pair, or the switching indication is used to instruct the terminal device to switch to the target beam pair.

[0289] Specifically, after receiving the first information, the network device may determine an available target resource group and then instruct the terminal device to switch to the target resource group, thereby facilitating normal communication between the network device and the terminal device and avoiding performance loss.

[0290] 408. The terminal device switches from the currently used resource group to the target resource group.

[0291] The above step 408 can also be described as: the terminal device switches from the currently used beam pair to the target beam pair.

[0292] 409. The terminal device communicates with the network device through the target resource group.

[0293] The above step 409 can also be described as: the terminal device communicates with the network device through the target beam pair.

[0294] Implementation 5: Optionally, the embodiment shown in FIG4 further includes steps 410 to 412. Steps 410 to 412 may be performed after step 402.

[0295] 410. The network device sends fifth indication information to the terminal device. Correspondingly, the terminal device receives the fifth indication information from the network device.

[0296] The fifth indication information is used to indicate the signal quality of the resources in the reporting target resource set.

[0297] In this implementation, after the terminal device reports the first information, if the terminal device receives the fifth indication information, the terminal device will no longer continue to report the first information.

[0298] 411. The terminal device measures the resources of the target resource set to obtain the signal quality of the resources of the target resource set.

[0299] 412. The terminal device sends the signal quality of the resources in the target resource set to the network device. Correspondingly, the network device receives the signal quality of the resources in the target resource set from the terminal device.

[0300] In an embodiment of the present application, a terminal device determines first information, and the first information includes at least one of the following: identifiers of one or more available resource groups, identifiers of resources in one or more available resource groups, signal quality of resources in one or more available resource groups, one or more report identifiers, identifiers of resource groups corresponding to one or more report identifiers, identifiers of resources in resource groups corresponding to one or more report identifiers, signal quality of resources in resource groups corresponding to one or more report identifiers, identifiers of one or more unavailable resource groups, identifiers of resources in one or more unavailable resource groups, signal quality of resources in one or more unavailable resource groups, first indication information, second indication information, or third indication information. Among them, the first indication information is used to indicate whether one or more resource groups reported by the terminal device are available or to indicate whether resources in one or more resource groups are available, or the first indication information is used to indicate whether the resource group currently used by the terminal device or the resources in the resource group are available. The second indication information is used to indicate one or more resource groups reported by the terminal device, or to indicate the resource group currently used by the terminal device. The third indication information is used to indicate whether the signal quality difference between two resources in the resource group indicated by the second indication information is greater than a first threshold. Then, the terminal device sends the first information to the network device. Therefore, it can be seen that the terminal device can report the first information, so that the terminal device can actively and promptly report the signal quality or availability of the resource group (also called the same-receive beam pair or the same-transmit beam pair) in the multi-beam scenario. This avoids the problem that due to certain factors, the same-receive beam pair or the same-transmit beam pair of the terminal device cannot be maintained, and the network device is unable to know in time. The network device schedules the terminal device to transmit based on the poor-quality same-receive beam pair or the same-transmit beam pair, which will lead to serious performance loss.

[0301] The present application also provides another embodiment, which is similar to the embodiment shown in FIG4 , except that the first information includes at least one of the following: identifiers of one or more available resources, signal quality of one or more available resources, one or more report identifiers, one or more report configuration identifiers, identifiers of resources corresponding to the one or more report identifiers, identifiers of resources corresponding to the one or more report configuration identifiers, signal quality of resources corresponding to the one or more report identifiers, signal quality of resources corresponding to the one or more report configuration identifiers, identifiers of one or more unavailable resources, signal quality of one or more unavailable resources, first indication information, second indication information, or third indication information. The first indication information is used to indicate whether one or more resources reported by a terminal device are available, or the first indication information is used to indicate whether resources currently used by the terminal device are available. The second indication information is used to indicate one or more resources reported by the terminal device, or the resources currently used by the terminal device. The third indication information is used to indicate whether the signal quality difference between two resources indicated by the second indication information is greater than a first threshold. For the first threshold, please refer to the relevant description of the embodiment shown in FIG4 . The resources corresponding to the one or more report identifiers include at least one resource corresponding to the one or more report identifiers. The resources corresponding to the one or more report configuration identifiers include at least one resource corresponding to the one or more report configuration identifiers.

[0302] Specifically, the terminal device is in a single TRP transmission mode. In a single beam scenario, the terminal device can report one or more resources through a beam management process. For the one or more resources reported by the terminal device, the terminal device can measure the signal quality of the one or more resources. Thus, the terminal device can determine whether the one or more resources are available and determine the first information.

[0303] In other words, the first information includes at least one of the following: an identifier of one or more available beams, a signal quality of one or more available beams, one or more reporting identifiers, one or more reporting configuration identifiers, an identifier of a beam corresponding to one or more reporting identifiers, an identifier of a beam corresponding to one or more reporting configuration identifiers, a signal quality of a beam corresponding to one or more reporting identifiers, an identifier of one or more unavailable beams, an identifier of one or more unavailable beams, a signal quality of one or more unavailable beams, first indication information, second indication information, or third indication information. The first indication information is used to indicate whether one or more beams reported by the terminal device are available, or the first indication information is used to indicate whether the beam currently used by the terminal device is available. The second indication information is used to indicate one or more beams reported by the terminal device, or to indicate the beam currently used by the terminal device. The third indication information is used to indicate whether the signal quality difference between the two beams indicated by the second indication information is greater than a first threshold.

[0304] Some examples of the content included in the first information are similar to the embodiment shown in Figure 4 above. For details, please refer to the relevant description of the embodiment shown in Figure 4 above. For example, in one possible implementation, the first information includes first indication information. In this implementation, the first information may optionally also include at least one of the following: the identification of one or more available resources, the signal quality of one or more available resources, the identification of one or more unavailable resources, or the signal quality of one or more unavailable resources. For example, the first information includes the first indication information, the identification of one or more available resources, and the signal quality of one or more available resources. For another example, the first information includes the first indication information, the identification of one or more unavailable resources, and the signal quality of one or more unavailable resources. In another possible implementation, the first information includes the identification of one or more available resources and the signal quality of one or more available resources. In yet another possible implementation, the first information includes one or more report identifiers and the identification of the beams corresponding to the one or more report identifiers. In yet another possible implementation, the first information includes one or more report configuration identifiers and the identification of the beams corresponding to the one or more report configuration identifiers. In yet another possible implementation, the first information includes the identification of one or more unavailable beams and the signal quality of one or more unavailable beams. In another possible implementation, the first information includes: second indication information and third indication information.

[0305] Optionally, the first information is sent via a first resource. The first resource is a PUCCH resource and / or a PUSCH resource. Optionally, the PUCCH resource may be a periodic PUCCH resource. The PUSCH resource may be a CG-PUSCH resource, a preconfigured PUSCH resource, or a PUSCH resource used for data transmission of a terminal device.

[0306] Optionally, when the first condition is met, the terminal device sends the first information to the network device. Correspondingly, when the first condition is met, the network device receives the first information from the terminal device. The first condition includes at least one of the following: the signal quality of at least one resource among the one or more resources reported by the terminal device is less than a preset threshold, or the signal quality of at least one resource among the one or more resources reported by the terminal device is less than or equal to the preset threshold; or the signal quality of the resource with the best signal quality among the one or more resources reported by the terminal device is less than the preset threshold, or the signal quality of the resource with the best signal quality among the one or more resources reported by the terminal device is less than or equal to the preset threshold. It should be noted that the preset threshold is similar to the second threshold in the embodiment shown in Figure 4 above, and please refer to the relevant introduction above for details. Optionally, when the terminal device is in single TRP transmission mode and the first condition is met, the terminal device sends the first information to the network device.

[0307] Another difference from the embodiment shown in Figure 4 is that the first configuration information also includes fourth indication information, and the fourth indication information is used to indicate whether the first resource is used to report whether one or more resources are available, and each of the one or more resources is used to determine the corresponding parameters for uplink transmission or downlink reception. In other words, the fourth indication information is used to indicate whether one or more beams are available. Optionally, the fourth indication information can also be carried in other information, which is not limited in this application. For example, as shown in Figure 6, the network device triggers a report of an event that configures a beam for the terminal device. Then, the terminal device measures the beam. When the terminal device determines that there is an unavailable beam, the terminal device can send the first information to the network device via a MAC CE. The MAC CE can be carried on the PUSCH resource of the terminal device for data transmission. There is no need to configure dedicated resources, saving resources.

[0308] Optionally, the first resource is associated with one or more specific reporting identifiers, and the first resource is used to report whether the one or more resources corresponding to the one or more specific reporting identifiers are available. In other words, the one or more available resources, the one or more unavailable resources, the resources corresponding to the one or more reporting identifiers, the resources corresponding to the one or more reporting configuration identifiers, the one or more unavailable resources, the resources currently used by the terminal device, and / or the one or more resources reported by the terminal device belong to the one or more resources corresponding to the one or more specific reporting identifiers. When the reporting conditions for the terminal device to report the first information are met, the first resource is a valid resource or an available resource. That is, the terminal device considers the first resource to be a valid resource or an available resource.

[0309] It should be noted that, in this embodiment, after the terminal device sends the first information to the network device, some possible implementation schemes of the terminal device and the network device do not include implementation scheme 1 of step 403 in the embodiment shown in Figure 4 above, and do not include implementation scheme 3 of steps 405 to 406 in the embodiment shown in Figure 4 above.

[0310] For implementation scheme 4, the switching indication in step 407 of the embodiment shown in Figure 4 above is replaced by the description: the switching indication is used to indicate the target resource, or the switching indication is used to instruct the terminal device to switch to the target resource. The step 408 in the embodiment shown in Figure 4 above is replaced by the description: the terminal device switches from the currently used resource to the target resource. That is, the terminal device switches from the currently used beam to the target beam. The step 409 in the embodiment shown in Figure 4 above is replaced by the description: the terminal device communicates with the network device through the target resource.

[0311] For implementation scheme 5, the fifth indication information in step 410 of the embodiment shown in Figure 4 above is replaced with the description: the fifth indication information is used to indicate the signal quality corresponding to one or more target resources. The step 411 in the embodiment shown in Figure 4 above is replaced with the description: the terminal device measures one or more target resources to obtain the signal quality of the one or more target resources. The step 412 in the embodiment shown in Figure 4 above is replaced with the description: the terminal device sends the signal quality corresponding to the one or more target resources to the network device. Correspondingly, the network device receives the signal quality corresponding to the one or more target resources from the terminal device.

[0312] Therefore, it can be seen that in this embodiment, the terminal device can report the first information, so that the terminal device can actively and promptly report the signal quality or availability of one or more resources in a single-beam scenario. This avoids the problem that due to certain factors, the uplink transmit beam or downlink receive beam of the terminal device cannot be maintained, and the network device is unable to know in time, and the network device schedules the terminal device to transmit based on the poor quality uplink transmit beam or downlink receive beam, which will lead to serious performance loss.
