Description

Technical Field

[0001] This application relates to the field of communication technology, and in particular to an information transmission method and apparatus. Background Technology

[0002] Fifth-generation (5G) mobile communication systems can employ high-frequency communication, meaning they use high-frequency signals to transmit data. A major problem with high-frequency communication is that signal energy decreases sharply with transmission distance, resulting in short transmission ranges. To overcome this problem, high-frequency communication uses analog beamforming technology. By weighting the antenna array, the signal energy is concentrated within a small angular range, forming a beam-like signal (called an analog beam, or simply a beam), thereby increasing the transmission distance. Network devices and terminal devices use beamforming for transmission.

[0003] During uplink and downlink data transmission, network devices and terminal devices need to use specific beams. The specific beam used for transmission is determined through beam measurement. In multi-station transmission mode, the network device can configure two resource sets for the terminal device, corresponding to two different transmission and reception points (TRPs). Each resource set contains one or more resources. For each resource, the network device transmits the signal corresponding to that resource through a beam, which the terminal device uses to measure the beam quality of the corresponding TRP. The terminal device pairs and reports the resources from the two resource sets, that is, it selects one resource with better quality from each resource set to form a pair and reports it to the network device. The terminal device can report one or more such resource groups (or beam groups), as well as the reference signal received power (RSRP) of each resource within each resource group.

[0004] According to the above method, network devices can schedule terminal devices for downlink transmission based on the resource groups reported by the terminal devices, but cannot schedule terminal devices for uplink transmission. Therefore, how to enable network devices to determine how to schedule terminal devices for uplink transmission during the measurement process is an urgent problem to be solved. Summary of the Invention

[0005] This application provides an information transmission method and apparatus to solve the problem of how terminal devices report information during the measurement process, so that network devices can determine how to schedule terminal devices for uplink transmission.

[0006] Firstly, this application provides an information transmission method for implementing functions on the terminal device side. For example, the method can be applied to the terminal device or a chip within the terminal device. The embodiments of this application are not limited to the specific executing entity of the method. Optionally, the method can be jointly implemented by multiple functional modules on the terminal device side, and the methods executed by each functional module are also within the protection scope of this application. Taking the application of this method to a terminal device as an example, in this method, the terminal device measures reference signal resources in X resource sets to determine M resource groups; X is an integer greater than 1, and M is an integer greater than 0; each resource set includes at least M reference signal resources, and each resource group includes X reference signal resources, with the X reference signal resources in each resource group belonging to different resource sets within the X resource sets; the terminal device sends first indication information and second indication information to a network device; wherein, the first indication information is used to indicate the M resource groups; the second indication information includes panel information corresponding to N resource groups in the M resource groups, where N is an integer less than or equal to M.

[0007] By using the above method, the terminal device can report the panel information of the resource group, which enables the network device to determine the uplink transmission-related information based on the panel information, thereby enabling efficient scheduling of the terminal device.

[0011] In one possible implementation, the N resource groups are preset N resource groups among the M resource groups.

[0012] In one possible implementation, before the terminal device measures the reference signal resources in the X resource sets, the method further includes: the terminal device sending L1 first parameters to the network device, each first parameter indicating a maximum number of transmission ports, the maximum number of transmission ports indicated by different first parameters being different, and L1 being an integer greater than 0.

[0018] In one possible implementation, each resource group includes two reference signal resources. If the two reference signal resources in the resource group corresponding to the panel information correspond to different panels, the panel information is also used to indicate whether the two panels corresponding to the two reference signal resources in the resource group corresponding to the panel information can be used for uplink multi-panel simultaneous transmission.

The X resource sets are used to determine M resource groups, where X is an integer greater than 1 and M is an integer greater than 0. Each resource set includes at least M reference signal resources, and each resource group includes X reference signal resources.

Detailed Implementation

[0046] The embodiments of this application will now be described in detail with reference to the accompanying drawings.

[0047] The communication method provided in this application can be applied to fourth-generation (4G) communication systems, such as Long Term Evolution (LTE), and also to fifth-generation (5G) communication systems, such as 5G New Radio (NR), or to various future communication systems, such as sixth-generation (6G) communication systems.

[0048] The methods and apparatus provided in this application are based on the same or similar technical concepts. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and repeated parts will not be described again.

[0049] The following section will first explain some of the terms used in the embodiments of this application so that those skilled in the art can understand them.

[0050] 1) The beam involved in the embodiments of this application is a communication resource. The beam can be a wide beam, a narrow beam, or other types of beams, and the beamforming technology can be beamforming technology or other technical means. Beamforming technology can specifically be digital beamforming technology, analog beamforming technology, and hybrid digital / analog beamforming technology. Different beams can be considered as different resources.

[0051] A beam can be referred to as a spatial domain filter, spatial filter, spatial domain parameter, spatial parameter, spatial domain setting, spatial setting, quasi-colocation (QCL) information, QCL hypothesis, or QCL indication, etc. The beam can be indicated by transmission configuration indicator state (TCI-state) parameters or by spatial relation parameters. Therefore, in this application, beam can be replaced by spatial domain filter, spatial filter, spatial parameter, spatial parameter, spatial setting, spatial setting, QCL information, QCL hypothesis, QCL indication, TCI-state (including uplink TCI-state and downlink TCI-state), or spatial relation, etc. The above terms are also equivalent to each other. Beam can also be replaced with other beam-related terms, which are not limited herein.

[0052] The beam used to transmit signals can be called the transmission beam (Tx beam), spatial domain transmission filter, spatial transmission filter, spatial domain transmission parameter, spatial transmission parameter, spatial domain transmission setting, or spatial transmission setting. The downlink transmission beam can be indicated by TCI-state.

[0053] The beam used to receive signals can be called 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. The uplink transmit beam can be indicated by any of the following: spatial relation, uplink TCI-state, or a sounding reference signal (SRS) resource (indicating the transmit beam using that SRS). Therefore, the uplink beam can also be replaced by an SRS resource.

[0054] The transmitting beam can refer to the distribution of signal strength in different directions in space after a signal is transmitted through an antenna, while the receiving beam can refer to the distribution of signal strength in different directions in space of a wireless signal received from an antenna.

[0055] Furthermore, the beam can be a wide beam, a narrow beam, or other types of beam. The beamforming technology can be beamforming technology or other technologies. Specifically, beamforming technology can be digital beamforming technology, analog beamforming technology, hybrid digital beamforming technology, or hybrid analog beamforming technology, etc.

[0056] Beams are generally associated with resources. For example, during beam measurement, network devices measure different beams using different resources. The terminal device provides feedback on the measured resource quality, allowing the network device to determine the quality of the corresponding beam. Similarly, during data transmission, beam information is also indicated through its corresponding resources. For instance, network devices use the Transmission Configuration Indicator (TCI) field in downlink control information (DCI) to indicate the physical downlink shared channel (PDSCH) beam information of the terminal device.

[0057] Optionally, multiple beams with the same or similar communication characteristics can be considered as a single beam. A beam may include one or more antenna ports for transmitting data channels, control channels, and detection signals, etc. The one or more antenna ports forming a beam can also be considered as a set of antenna ports.

[0058] In the embodiments of this application, unless otherwise specified, a beam refers to the transmit beam of a network device. In beam measurement, each beam of a network device corresponds to a resource, and therefore the resource index can be used to uniquely identify the beam corresponding to that resource.

[0059] 2) The uplink beam involved in the embodiments of this application, in the current protocol, the uplink transmission beam can be indicated by spatial relation, which functions similarly to TCI-state, and is used to inform the terminal device which transmission beam to use for uplink transmission.

[0060] Spatial relations need to be configured via radio resource control (RRC) signaling. The configuration information includes the spatial relation identifier, cell identifier, target reference signal resource, path loss measurement reference signal, power control parameters, etc. The target reference signal resource indicates the corresponding uplink beam. If the uplink transmission uses spatial relation #1, and this spatial relation #1 includes a target reference signal resource #2, it indicates that the transmit beam used for this uplink transmission is the transmit / receive beam of this target reference signal. For example, when the target reference signal resource is an uplink resource sounding reference signal (SRS), it means that the transmit beam used for the uplink transmission is the transmit beam of this SRS (the transmit beam of this SRS is known). For example, if the target reference signal resource is a downlink resource such as a synchronization signal block (SSB) or channel state information reference signal (CSI-RS), it means that the transmit beam used for uplink transmission is the receive beam of that SSB / CSI-RS (the receive beam of that SSB / CSI-RS is known).

[0061] Network devices can configure multiple spatial relations for terminal devices. Then, a Media Access Control (MAC) control element (CE) activates one of these relations for the corresponding data transmission. Uplink transmission includes the Physical Uplink Control Channel (PUCCH), SRS, and Physical Uplink Shared Channel (PUSCH), all requiring corresponding spatial relations. The spatial relation of the PUCCH is indicated by MAC CE signaling. The spatial relation of the SRS is also indicated by MAC CE signaling. During PUSCH transmission, a specific SRS is associated with it, and the spatial relation of that SRS is used for transmission.

[0062] 3) The downlink beam involved in the embodiments of this application can be indicated by TCI-state.

[0063] Network devices can generate different beams pointing in different transmission directions. During downlink data transmission, when a network device uses a specific beam to send data to a terminal device, it needs to inform the terminal device of the transmitted beam information so that the terminal device can use the corresponding received beam to receive the data sent by the network device. In the 3rd Generation Partnership Project (3GPP) R15 / R16 protocol, the network device indicates the relevant information of the transmitted beam it uses to the terminal device through the Transmission Configuration Index (TCI) field in the Data Interface Certificate (DCI). Specifically, the TCI field is 3 bits in size and can represent 8 different field values ​​(codepoints). Each value of the TCI field corresponds to an index of a TCI-state, which uniquely identifies a TCI-state. The TCI-state includes several parameters that determine the relevant information of the transmitted beam. The TCI-state is configured by the network device for each terminal device, and each TCI-state includes its own index and two QCL information entries (QCL-Info). Each QCL-Info includes a cell field and a bandwidth part (BWP) identifier (bwp-Id), indicating which cell and BWP the TCI-state applies to. Different cells or different BWPs within the same cell can be configured with different QCL-Infos. The QCL-Info also includes a reference signal (RS) indicating which reference signal resource constitutes a QCL relationship. In the R15 / R16 protocols, the term "beam" is generally not used directly; it is usually replaced by other terms. For example, in data transmission and channel measurements, beams correspond to reference signal resources, with one beam corresponding to one reference signal resource. Therefore, when we say a QCL relationship exists with a reference signal resource, we are essentially referring to which beam constitutes the QCL relationship. A QCL relationship means that two reference signal resources (or two antenna ports, with a one-to-one correspondence between antenna ports and reference signal resources) share certain spatial parameters. Which spatial parameters are identical depends on the type of the QCL-Info, specifically the QCL type (qcl-Type) field. The QCL type can have four values: {typeA, typeB, typeC, typeD}. Taking typeD as an example, typeD indicates that the two reference signal resources have the same spatial reception parameter information, that is, the two beams have the same reception beam.At most one of the two QCL-Info values ​​included in the TCI-state can be typeD.

[0064] 4) The common beam involved in the embodiments of this application refers to a beam indicated by the network device to the terminal device. This beam can be used simultaneously for multiple channels and / or reference signals. In the embodiments of this application, this beam is called a common beam, but it can also be called by other names. This application does not make a specific limitation. Furthermore, the common beam can include an uplink common beam, a downlink common beam, and an uplink-downlink common beam. The uplink common beam can be used for the transmission of multiple uplink channels and / or uplink reference signals, and the downlink common beam can be used for the transmission of multiple downlink channels and / or downlink reference signals. The uplink-downlink common beam can be used for the transmission of multiple uplink channels and / or uplink reference signals, as well as multiple downlink channels and / or downlink reference signals. That is, the uplink-downlink common beam can be used for both uplink and downlink transmission.

[0065] It should be noted that the aforementioned common beam can specifically refer to TCI-state or other terms, and this application does not impose a specific limitation. Furthermore, unless otherwise specified, in the embodiments of this application, the common beam can refer to any one of the uplink common beam, downlink common beam, and uplink / downlink common beam.

[0066] (5) The antenna panel involved in the embodiments of this application can be an antenna panel of a network device or an antenna panel of a terminal device. An antenna panel generally has one or more antennas, which form an antenna array to perform beamforming, thereby forming an analog beam. This antenna array can generate beams pointing in different directions, but only one beam can be generated at a time. That is, multiple beams can be formed on each antenna panel, and beam measurement can be used to determine which beam is best for the antenna panel. A terminal device can be equipped with multiple antenna panels, which can be distributed in different locations and facing different directions. This ensures that regardless of the direction the terminal device faces, at least one antenna panel is facing the network device, enabling data transmission with the network device. For example... Figure 1 As shown, the terminal device is equipped with two antenna panels, each facing a different direction. Each antenna panel can generate multiple beams in different directions, thus forming a relatively comprehensive beam coverage. Figure 1 The following description uses an example where a terminal device generates beam 1 through antenna panel 1 and beam 2 through antenna panel 2. The terminal device can simultaneously activate all antenna panels for transmission. Alternatively, to reduce power consumption, the terminal device can use only a single antenna panel for transmission, while other unused antenna panels can be deactivated. The terminal device typically needs to notify the network device whether its antenna panels are on or off.

[0067] In the embodiments of this application, the antenna panel can be simply referred to as a panel, and the antenna panel can also be represented by the antenna panel index, etc. In addition, antenna panels can be implicitly represented in other ways. For example, antenna panels can be represented by antenna ports (such as CSI-RS ports, SRS ports, demodulation reference signal (DMRS) ports, phase tracking reference signal (PTRS) ports, CRS ports, time-frequency tracking reference signal (TRS) ports, SSB ports, etc.) or groups of antenna ports. They can also be represented by resources (such as CSI-RS resources, SRS resources, DMRS resources, PTRS resources, cell reference signal (CRS) resources, TRS resources, SSB resources, etc.) or groups of resources. They can also be represented by a channel (such as PUCCH, PUSCH, physical random access channel (PRACH), PDSCH, PDCCH, physical broadcast channel (PBCH), etc.). They can also be represented by beams, QCL, TCI-state, spatial relation, or an index configured in QCL, TCI-state, spatial relation. It can also be characterized by beam groups, QCL groups, TCI-state groups, spatial relation groups, etc. In other words, the antenna panel / panel designation described in this application can be replaced with the designations mentioned above.

[0068] (6) In the embodiments of this application, "multiple" refers to two or more. "And / or" describes the relationship between related objects, indicating that there can be three relationships. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the related objects before and after are in an "or" relationship. In addition, it should be understood that in the description of this application, words such as "first" and "second" are only used for the purpose of distinguishing descriptions and should not be construed as indicating or implying relative importance or order.

[0069] (7) The terms "comprising" and "having," and any variations thereof, mentioned in the description of the embodiments of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or devices. It should be noted that in the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0070] The network devices involved in the embodiments of this application can be devices in a wireless network. For example, a network device can be a device deployed in a radio access network to provide wireless communication functions for terminal devices. For example, a network device can be a radio access network (RAN) node that connects terminal devices to a wireless network, and can also be called an access network device.

[0071] Network equipment includes, but is not limited to: evolved Node B (eNB), radio network controller (RNC), Node B (NB), base station controller (BSC), base transceiver station (BTS), home base station (e.g., home-evolved Node B, or home Node B, HNB), baseband unit (BBU), access point (AP), wireless relay node, wireless backhaul node, transmission point (TP), or transmission and reception point (TRP) in a wireless fidelity (WIFI) system, and can also be network equipment in a 5G mobile communication system. For example, next-generation Node B (gNB), transmission and reception point (TRP), or 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, network equipment can also be network nodes constituting a gNB or transmission point. For example, BBU, or distributed unit (DU), etc.

[0072] In some deployments, a gNB may include a centralized unit (CU) and a dedicated unit (DU). A gNB may also include an active antenna unit (AAU). The CU implements some of the gNB's functions, and the DU implements others. For example, the CU handles non-real-time protocols and services, implementing Radio Resource Control (RRC) and Packet Data Convergence Protocol (PDCP) layer functions. The DU handles physical layer protocols and real-time services, implementing Radio Link Control (RLC), MAC, and physical (PHY) layer functions. The AAU implements some physical layer processing functions, radio frequency processing, and active antenna-related functions. Information from the RRC layer ultimately becomes information from the PHY layer, or is derived from PHY layer information. Therefore, in this architecture, higher-layer signaling (such as RRC layer signaling) can be considered to be sent by the DU, or by both the DU and AAU. It is understood that network devices can be one or more of CU nodes, DU nodes, and AAU nodes. In addition, the CU can be classified as a network device in the RAN or as a network device in the core network (CN), and this application does not limit this.

[0073] The terminal device involved in the embodiments of this application can be a wireless terminal device capable of receiving network device scheduling and instruction information. The terminal device can be a device that provides voice and / or data connectivity to the user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem.

[0074] Terminal equipment, also known as user equipment (UE), mobile station (MS), or mobile terminal (MT), is a device that includes wireless communication capabilities (providing voice / data connectivity to users). Examples include handheld devices with wireless connectivity and in-vehicle devices. Currently, some examples of terminal equipment include: mobile phones, tablets, laptops, PDAs, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in vehicle-to-everything (V2X) communication, wireless terminals in self-driving cars, wireless terminals in remote medical surgery, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, and wireless terminals in smart homes. For example, wireless terminals in V2X communication can be in-vehicle equipment, vehicle-mounted equipment, in-vehicle modules, or vehicles themselves. In industrial control, wireless terminals can be cameras, robots, etc. In smart homes, wireless terminals can be televisions, air conditioners, robot vacuums, speakers, set-top boxes, etc.

[0075] The following is a brief introduction to the technology of communication using beams.

[0076] In 5G communication systems, data transmission between network devices and terminal devices can be performed using beamforming. The network device can decide which beam to use, while the terminal device receives instructions from the network device regarding the beam to be used. For example, the network device sends downlink control information to the terminal device. This downlink control information includes a Transmission Configuration Number (TCI) field, which indicates a TCI-state used for either uplink or downlink transmission. This TCI-state includes a target reference signal resource. When using this TCI-state for downlink transmission, the terminal device uses the receive beam corresponding to the target reference signal resource. Since the receive beam corresponding to the target reference signal resource is already determined by the terminal device, the network device can instruct the terminal device to use the correct receive beam. When using this TCI-state for uplink transmission, the terminal device uses either the transmit beam or the receive beam corresponding to the target reference signal for transmission.

[0077] For terminal devices equipped with multiple antenna panels, the terminal device can support multi-station transmission mode. In multi-station transmission mode, the terminal device can use two antenna panels to transmit simultaneously with two different transmission and reception points (TRPs). For example, as... Figure 2 The diagram illustrates a multi-station transmission mode according to an embodiment of this application. The terminal device can transmit data with multiple TRPs. The diagram uses two TRPs as an example, namely TRP1 and TRP2. The multiple TRPs may belong to the same cell or different cells. When they belong to the same cell, the measurement parameters of the multiple TRPs are configured uniformly. When they belong to different cells, the measurement parameters of each TRP are configured individually.

[0078] When a terminal device transmits data simultaneously with two TRPs, the network device can configure two resource sets for the terminal device, each corresponding to a different TRP. Each resource set contains one or more resources. For each resource, the network device transmits the signal corresponding to that resource through a beam to measure the beam quality of the corresponding TRP. The terminal device can pair and report resources from the two resource sets, that is, it selects one resource with better quality from each resource set to form a pair and report it to the network device. The terminal device can report one or more such resource groups (or beam groups), as well as the RSRP of each resource within each resource group.

[0079] Furthermore, the terminal device needs to ensure that the two resources in each resource group can be received simultaneously. This allows the network device to determine, based on the resource group information reported by the terminal device, which beams to send to the terminal device for each of the two TRPs, thus enabling simultaneous transmission of multiple TRPs. For example... Figure 3 As shown, there are two scenarios where two resources in each resource group can be received simultaneously by the terminal device: Scenario 1, such as... Figure 3 As shown in (a), the two resources in this resource group are received by the same receiving beam on the same antenna panel of the terminal device. The figure describes the terminal device receiving resource 1 and resource 2 through antenna panel 1 as an example; Case 2, as... Figure 3 As shown in (b), the two resources in this resource group are received by the receiving beams on the two antenna panels of the terminal device. That is, each antenna panel can generate a beam, and the receiving beams of the two resources are located on the two antenna panels respectively. The figure describes the terminal device receiving resource 1 through antenna panel 1 and receiving resource 2 through antenna panel 2 as an example.

[0080] This application provides a method in which a terminal device not only reports to a network device the resource groups that it can receive simultaneously, i.e., two TRPs can transmit signals to the terminal device simultaneously using the beams corresponding to the resources in the resource group, but the terminal device can also report to the network device the panel information corresponding to each resource in the resource group, so that the network device can determine whether the receiving beams corresponding to the resources in the resource group are the same beams on the same panel or beams on different panels, thereby enabling the network device to perform multi-panel uplink transmission scheduling.

As those skilled in the art will know, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0088] The following process is mainly described using the example of a terminal device transmitting with a maximum of two TRPs simultaneously. That is, the network device configures a maximum of two resource sets for the terminal device, and the resource group reported by the terminal device includes a maximum of two resources. When the network device configures three or more resource sets, and the resource group reported by the terminal device includes three or more resources, adaptive adjustments can be made according to the method provided in this application.

[0089] like Figure 4 The diagram shown is a flowchart of an information transmission method provided in an embodiment of this application. The method includes: S401: The terminal device sends capability information to the network device.

[0090] This capability information can indicate at least one of the following: Does the terminal device support reporting the panel information corresponding to the resource group when reporting the resource group (beam group)? The terminal device supports reporting panel information for a number of resource groups, Q, where Q is an integer greater than 0. Does the terminal device support simultaneous transmission of multiple beams or multiple panels? The panel capability information of the terminal device can be used to indicate information such as the maximum number of transmission ports supported by the panel of the terminal device.

[0091] The transmitting port can refer to an SRS port, etc. The maximum number of transmitting ports can be a number greater than or equal to 0, or a number greater than 0. If the maximum number of transmitting ports for a panel is 0, it means that the panel is only used for downlink transmission and not for uplink transmission.

[0092] Assume the terminal device comprises X panels, where X is a positive integer. Each panel corresponds to a maximum number of transmission ports. The maximum number of transmission ports for different panels may be the same or different. The specific content of the panel capability information of the terminal device may be implemented in the following ways.

[0093] In the first implementation, the panel capability information includes L1 first parameters, where L1 is an integer greater than 0. Each first parameter indicates a maximum number of transmitting ports, and different first parameters indicate different maximum numbers of transmitting ports. Each first parameter can also correspond to an index, and different first parameters correspond to different indices. When reporting each first parameter, the terminal device can report the index of each first parameter simultaneously, or it can choose not to report the index. If the index is not reported, it can be preset. For example, the L1 first parameters reported by the terminal device are arranged in a preset order, and the index of each first parameter corresponds to this order. For instance, the index of the first first parameter is 0, the index of the second first parameter is 1, and so on.

[0094] If the maximum number of transmitting ports reported by the terminal device is a number greater than or equal to 0, and the maximum number of transmitting ports corresponding to X panels has Y1 different values, where Y1 is an integer greater than or equal to 0, then the value of L1 can be less than or equal to Y1.

[0095] If the maximum number of transmitting ports reported by the terminal device is a number greater than 0, and the X maximum number of transmitting ports includes the maximum number of transmitting ports with a value of 0, then the value of L1 can be less than or equal to Y1-1; if the X maximum number of transmitting ports does not include the maximum number of transmitting ports with a value of 0, then the value of L1 can be less than or equal to Y1.

[0096] For example, suppose the terminal device has three panels: the first panel, the second panel, and the third panel. The maximum number of transmitting ports for these three panels are 1, 1, and 2, respectively; then Y1=2, L1=2. The terminal device reports two first parameters to the network device, and these two first parameters are the maximum number of transmitting ports, as shown in Table 1.

[0097] Table 1

[0098] Assume the terminal device has three panels: the first panel, the second panel, and the third panel. The maximum number of transmission ports corresponding to these three panels are 0, 1, and 2, respectively; then Y1 = 3. If the maximum number of transmission ports reported by the terminal device is greater than or equal to 0, then the terminal device reports three first parameters, which can be represented by the maximum number of transmission ports as shown in Table 2.

[0099] Table 2

[0100] If the maximum number of sending ports reported by the terminal device is a number greater than 0, then the terminal device reports two first parameters, which are the maximum number of sending ports as shown in Table 3.

[0101] Table 3

[0102] In the second implementation, the panel capability information includes L2 second parameters, where L2 is an integer greater than 0. Each second parameter indicates one or more maximum transmission ports. Each second parameter can also correspond to an index, with different indices for different second parameters. When reporting each second parameter, the terminal device can report the index of each second parameter simultaneously, or it can choose not to report the index. If the index is not reported, it can be preset. For example, the L2 second parameters reported by the terminal device can be arranged in a preset order, and the index of each second parameter corresponds to this order. For instance, the index of the first second parameter might be 0, the index of the second second parameter might be 1, and so on.

[0103] If the maximum number of transmitting ports reported by the terminal device is a number greater than or equal to 0, and there are Y1 different values ​​for the maximum number of transmitting ports corresponding to X panels, and among the Y1 values ​​there are Y3 values ​​for the maximum number of transmitting ports corresponding to multiple panels, where Y3 is an integer greater than or equal to 0, then the value of L2 can be less than or equal to Y1+Y3+Y1×(Y1-1).

[0104] If the maximum number of transmitting ports reported by the terminal device is a number greater than 0, and there are Y2 different values ​​greater than 0 among the X maximum number of transmitting ports corresponding to X panels, and there are Y4 values ​​among the Y2 values ​​that correspond to multiple panels, where Y4 is an integer greater than or equal to 0, then the value of L2 can be less than or equal to Y2 + Y4 + Y2 × (Y2 - 1).

[0105] Wherein, if a second parameter is used to indicate a maximum number of transmission ports, the maximum number of transmission ports indicated by the second parameter corresponds to a panel of the terminal device; if a second parameter is used to indicate multiple maximum numbers of transmission ports, then each of these multiple maximum numbers of transmission ports corresponds to a panel of the terminal device, that is, these multiple maximum numbers of transmission ports respectively represent the maximum number of transmission ports of multiple panels of the terminal device.

[0106] For example, suppose the terminal device has three panels, namely the first panel, the second panel and the third panel, and the maximum number of transmission ports corresponding to these three panels are 1, 1 and 2 respectively; then Y1=2 and Y3=1.

[0107] Therefore, the terminal device needs to report 5 = 2 + 1 + 2 × (2 - 1) second parameters. The maximum number of sending ports indicated by these 5 second parameters can be shown in Table 4.

[0108] Table 4

[0109] Where {1} indicates that the second parameter corresponds to a single panel, and the maximum number of transmission ports for that panel is 1. {2} is similar to {1}. {1,1} indicates that the second parameter corresponds to two panels, and the maximum number of transmission ports for these two panels are 1 and 1 respectively. {1,2} and {2,1} are similar to {1,1}. The difference between {1,2} and {2,1} is that {1,2} indicates that the maximum number of transmission ports for the first and second panels of the two panels corresponding to the second parameter are 1 and 2 respectively, while {2,1} indicates that the maximum number of transmission ports for the first and second panels of the two panels corresponding to the second parameter are 2 and 1 respectively.

[0110] Assume the terminal device has three panels: the first panel, the second panel, and the third panel. The maximum number of transmission ports corresponding to these three panels are 0, 1, and 2, respectively. If the maximum number of transmission ports reported by the terminal device is greater than or equal to 0, then Y1=3, Y3=0, and the terminal device needs to report 9=3+0+3×(3-1) second parameters. The maximum number of transmission ports indicated by these 9 second parameters can be shown in Table 5.

[0111] Table 5

[0112] If the maximum number of sending ports reported by the terminal device is a number greater than 0, then Y2=2, Y4=0, and the terminal device needs to report 4=2+0+2×(2-1) second parameters. The maximum number of sending ports indicated by these 4 second parameters can be shown in Table 6.

[0113] Table 6

[0114] In the third implementation, the panel capability information includes L2 second parameters. Each second parameter indicates one or more maximum transmission ports and the number of panels corresponding to those maximum transmission ports. Each second parameter can also correspond to an index, with different indices for different second parameters. The values ​​of L2 can be found in the previous description and will not be repeated here.

[0115] For example, suppose the terminal device has three panels, namely the first panel, the second panel and the third panel, and the maximum number of transmission ports corresponding to these three panels are 1, 1 and 2 respectively; then Y1=2 and Y3=1.

[0116] Therefore, the terminal device needs to report 5 = 2 + 1 + 2 × (2 - 1) second parameters. The maximum number of sending ports indicated by these 6 second parameters can be shown in Table 7.

[0117] Table 7

[0118] In this configuration, the last parameter in each second parameter represents the number of panels corresponding to that parameter, while the preceding one or two parameters represent the maximum number of transmitting ports corresponding to one or two panels. For example, if the second parameter is {2, 1}, the last number 1 indicates that this parameter corresponds to one panel, and the first number 2 indicates that the maximum number of transmitting ports for that panel is 2. If the second parameter is {1, 2, 2}, the last number 2 indicates that this parameter corresponds to two panels, and the first number 2 and the second number 1 indicate that the maximum number of transmitting ports for the two panels are 1 and 2, respectively.

[0119] Assume the terminal device has three panels: the first panel, the second panel, and the third panel. The maximum number of transmission ports corresponding to these three panels are 0, 1, and 2, respectively. If the maximum number of transmission ports reported by the terminal device is greater than or equal to 0, then Y1=3, Y3=0, and the terminal device needs to report 9=3+0+3×(3-1) second parameters. The maximum number of transmission ports indicated by these 9 second parameters can be shown in Table 8.

[0120] Table 8

[0121] If the maximum number of sending ports reported by the terminal device is a number greater than 0, then Y2=2, Y4=0, and the terminal device needs to report 4=2+0+2×(2-1) second parameters. The maximum number of sending ports indicated by these 4 second parameters can be shown in Table 9.

[0122] Table 9

[0123] The above are just examples. The parameters included in the panel capability information may have other possible implementations, and this application does not limit them.

[0124] S402: The network device sends configuration information to the terminal device. This configuration information is used to configure X resource sets, where X is an integer greater than 1.

[0125] Each of the X resource sets includes at least M reference signal resources, and each reference signal resource can correspond to a beam. In a resource set, the beams corresponding to different reference signal resources can be the same or different, and this application does not limit this.

[0126] There are several ways network devices can send configuration information. For example, a network device can send configuration information to a terminal device via higher-layer signaling. This configuration information indicates X resource sets. Specifically, the network device can configure X resource sets in the resource configuration or resource setting fields of the higher-layer signaling. For each reference signal resource in the X resource sets, this configuration information can indicate the starting position and index of each reference signal resource.

[0127] This configuration information can also be used to configure relevant information for beam reporting by the terminal device, such as indicating one or more of the following: Configure terminal devices to report resource groups across resource sets; Configure the number of resource groups M to be reported. M is an integer greater than 0. For example, the value of M can be any one of {1, 2, 3, 4}. The value of N, which represents the number of resource groups to report panel information, indicates that the terminal device needs to report panel information corresponding to N out of M resource groups. N is an integer less than or equal to M and greater than 0.

[0128] N may not need to be configured, for example, the protocol may specify that N equals M; or it may be pre-agreed that N equals the minimum value between Q and M.

[0129] Optionally, if the panel capability information reported by the terminal device in S401 includes L1 first parameters, the network device can also determine L2 second parameters based on these L1 first parameters. Each second parameter indicates one or more maximum transmitting ports, or each second parameter indicates one or more maximum transmitting ports and the number of panels corresponding to those maximum transmitting ports. The network device can send the L2 second parameters to the terminal device through configuration information, or it can send the L2 second parameters to the terminal device separately. When sending the L2 second parameters, the network device can send the index of each second parameter simultaneously, or it can choose not to send the index. If the index of each second parameter is not sent, the index of each second parameter can be preset. For example, the L2 second parameters sent by the network device are arranged in a preset order, and the index of each second parameter corresponds to its order. For example, the index of the first second parameter is 0, the index of the second second parameter is 1, and so on.

[0130] Furthermore, taking a resource group that includes two reference signal resources as an example, the value of L2 determined by the network device can be less than or equal to L1 + L1 × L1.

[0131] For example, suppose each second parameter indicates one or more maximum transmission ports. The terminal device reports two first parameters, {1} and {2}. Then, the network device determines the number of second parameters L2 = 2 + 2 × 2 = 6 based on these two first parameters. These six second parameters are {1}, {2}, {1, 1}, {2, 2}, {1, 2}, and {2, 1}. The meaning of these second parameters can be found in the previous description of second parameters, and will not be repeated here. The L2 second parameters sent by the network device in this case can be shown in Table 10.

[0132] Table 10

[0133] Furthermore, taking a resource group that includes two reference signal resources as an example, the value of L2 determined by the network device can be less than or equal to L1 + L1 × L1.

[0134] For another example, suppose each second parameter indicates one or more maximum transmitting ports and the number of panels corresponding to those maximum transmitting ports. If the terminal device reports two first parameters, {1} and {2}, then the network device determines the number of second parameters L2 = 2 + 2 × 2 = 6 based on these two first parameters. These six second parameters are {1, 1}, {2, 1}, {1, 1, 2}, {2, 2, 2}, {1, 2, 2}, and {2, 1, 2}. The meaning of these second parameters can be found in the previous description of second parameters, and will not be repeated here. The L2 second parameters sent by the network device are shown in Table 11.

[0135] Table 11

[0136] S403: The network device sends reference signal resources from X resource sets to the terminal device.

[0137] Specifically, network devices can send reference signals to terminal devices through each reference signal resource in the X resource sets, and the reference signals in each reference signal resource are transmitted using the beam corresponding to that reference signal resource.

[0138] S404: The terminal device measures the reference signal resources in X resource sets to determine M resource groups.

[0139] The terminal device can measure the reference signal in each reference signal resource in X resource sets to obtain the measurement information corresponding to each reference signal resource. The measurement information can be RSRP or other information.

[0140] The terminal device can determine M resource groups based on measurement information obtained from measuring each reference signal resource in X resource sets. Each resource group determined by the terminal device consists of X reference signal resources selected from each of the X resource sets, resulting in a total of M resource groups. That is, each of the M resource groups includes X reference signal resources, and the X reference signal resources in each resource group belong to different resource sets within the X resource sets. Each reference signal resource can only belong to one resource group.

[0141] This application does not limit how the terminal device determines M resource groups from X resource sets. For example, in one possible implementation, assuming the measurement information is RSRP or signal-to-interference-plus-noise ratio (SINR), the terminal device can select one reference signal resource from each of the X resource sets, selecting a total of X reference signal resources. Once a reference signal resource from each resource set is selected into a resource group, it cannot be selected into another resource group. The reference signal resource selected by the terminal device from each resource set can be the reference signal resource with the largest RSRP or SINR in that resource set, and the terminal device can treat these X reference signal resources as a resource group. Then, the terminal device selects another reference signal resource from each resource set, selecting a total of X reference signal resources, which can then be treated as another group, and so on, so that the terminal device can determine M resource groups.

[0142] Furthermore, the terminal device can also identify N resource groups out of the M resource groups that need to report panel information. This application does not limit which N resource groups specifically need to report panel information. For example, the N resource groups with the highest average RSRP among the M resource groups can be selected as the resource groups that need to report panel information. Alternatively, the N resource groups with the lowest average RSRP among the M resource groups can also be selected as the resource groups that need to report panel information.

[0143] S405: The terminal device sends a first instruction message and a second instruction message to the network device; correspondingly, the network device receives the first instruction message and the second instruction message from the terminal device.

[0144] The terminal device can send the first instruction information and the second instruction information through a single message, or it can send the first instruction information and the second instruction information through different messages.

[0145] The first indication information is used to indicate the M resource groups. For example, the first indication information includes the index of each resource in the M resource groups. The first indication information may also indicate the measurement information of each reference signal resource in the M resource groups, such as the RSRP or SINR of each reference signal resource.

[0146] The second indication information can be used to indicate the panel information corresponding to N resource groups in M ​​resource groups. Specifically, the second indication information includes N panel information, and each panel information is used to indicate at least one of the following information for the resource group corresponding to that panel information: Information 1, the maximum number of transmission ports of the panel corresponding to each reference signal resource in the resource group; Information 2, whether the panels corresponding to X reference signal resources in the resource group are the same; Information 3, the number of panels corresponding to X reference signal resources in the resource group.

[0147] For example, if a resource group includes two reference signal resources, Information 1 may include two maximum transmit port numbers or indices of the maximum transmit port number. Information 2 and Information 3 in the panel information may be located before Information 1, as shown in Table 12.

[0148] Table 12

[0149] If the two reference signal resources in the resource group indicated by information 2 correspond to the same panel, then it can be assumed that the maximum number of transmission ports of the panels corresponding to these two reference signal resources is the same, and it can be determined that these two reference signal resources correspond to 1 panel. In this case, information 3 may not be included in the panel information, and information 2 may only include a maximum number of transmission ports or an index of the maximum number of transmission ports.

[0150] For another example, taking a resource group that includes two reference signal resources as an example, information one can include two maximum transmit port numbers or indices of maximum transmit port numbers. Information one in the panel information can be located before information two and information three, as shown in Table 13.

[0151] Table 13

[0152] If the two maximum transmit port numbers or maximum transmit port indexes included in Information 1 are different, then it can be assumed that the two reference signal resources correspond to different panels, and it can be determined that the two reference signal resources correspond to two panels. In this case, Information 2 and Information 3 may not be included in the panel information.

[0153] Optionally, the panel information may further be used to indicate the corresponding resource group of the panel information among the M resource groups, for example, the panel information is further used to indicate the resource group identity of the resource group corresponding to the panel information. For example, the panel information includes a resource group identity field, the field is used to indicate the resource group corresponding to the panel information, and the field may include the identity of the resource group corresponding to the panel information. The length of this field may be determined according to the size relationship between M and N. When N<M, the length of the field may be the ceiling of log2M; when N=M, the length of the field may be 0, and at this time, the N=M pieces of panel information reported are in one-to-one correspondence with the M resource groups, so it is unnecessary to specifically indicate the resource group corresponding to each piece of panel information.

[0154] If the panel information does not indicate the corresponding resource group of the panel information among the M resource groups, the positions of the N resource groups among the M resource groups may be pre-agreed. For example, the N resource groups with corresponding panel information are N preset resource groups among the M resource groups. For example, the M resource groups reported by the terminal device are arranged in the order of numbers, and it may be pre-agreed that the N resource groups with corresponding panel information are placed at the front, that is, the first N resource groups in the arrangement have corresponding panel information.

[0155] Through the above method, the terminal device can indicate which N resource groups among the M resource groups the N resource groups belong to.

[0156] Optionally, if two reference signal resources in the resource group corresponding to the panel information correspond to different panels, the panel information is further used to indicate whether the two panels corresponding to the two reference signal resources in the resource group corresponding to the panel information can be used for uplink multi-beam simultaneous transmission or uplink multi-panel simultaneous transmission, or to indicate whether the receive beams or panels corresponding to the two reference signal resources in the corresponding resource group can be used for uplink simultaneous transmission. If all resources in the resource group corresponding to the panel information correspond to the same panel, this information may not be included.

[0157] In the embodiments of the present application, the panel information may have multiple implementation manners, which are described below respectively by taking that a resource group includes two reference signal resources (which are a first reference signal resource and a second reference signal resource respectively) as an example.

[0158] In a first possible implementation, by taking that L1 first parameters are pre-agreed between a terminal device and a network device as an example, the panel information may include at least one of the following pieces of information: First information, where the first information is used to indicate one first parameter among the L1 first parameters, and the maximum number of transmit ports indicated by the first parameter corresponding to the first information is the maximum number of transmit ports of the panel corresponding to the first reference signal resource; The second information is used to indicate one of the L1 first parameters. The maximum number of transmission ports indicated by the first parameter corresponding to the second information is the maximum number of transmission ports of the panel corresponding to the second reference signal resource. The first information and the second information can indicate the maximum number of transmission ports of the panel corresponding to each reference signal resource in the resource group corresponding to the panel information. The third information is used to indicate whether the panels corresponding to the X reference signal resources in the resource group corresponding to the panel information are the same. The fourth information is used to indicate the number of panels corresponding to the X reference signal resources in the resource group.

[0159] The first information can be one of the L1 first parameters, an index of one of the L1 first parameters, or other information indicating the first parameter. The second information can be one of the L1 first parameters, an index of one of the L1 first parameters, or other information indicating the first parameter. If the panel information does not include the fourth information, the number of panels corresponding to the X reference signal resources in the resource group can be indicated indirectly. For example, when the X reference signal resources in the resource group corresponding to the panel information correspond to the same panel, it means that the number of panels corresponding to the X reference signal resources in the resource group is 1, and the fourth information may not be included. For example, when the resource group includes 2 reference signal resources, if the 2 reference signal resources in the resource group corresponding to the panel information correspond to different panels, it means that the number of panels corresponding to the 2 reference signal resources in the resource group is 2, and the fourth information may not be included.

[0160] For example, suppose the terminal device reports two first parameters, {1} and {2}, with corresponding indices of 0 and 1 respectively. If a resource group includes two reference signal resources, namely the first reference signal resource and the second reference signal resource, and the maximum number of transmission ports of the panel corresponding to the first reference signal resource is 1, and the maximum number of transmission ports of the panel corresponding to the second reference signal resource is 2, then the panel information corresponding to this resource group can be shown in Table 14.

[0161] Table 14

[0162] In this context, the first information being 0 indicates that the first parameter indicated by the first information is {1}, meaning it indicates the maximum number of transmitting ports of the panel corresponding to the first reference signal resource. The second information being 1 indicates that the first parameter indicated by the second information is {2}, meaning it indicates the maximum number of transmitting ports of the panel corresponding to the second reference signal resource. When the third information is 0, it indicates that the panels corresponding to the first and second reference signal resources are different; conversely, if the third information is 1, it indicates that the panels corresponding to the first and second reference signal resources are the same. When the fourth information is 1, it indicates that the number of panels corresponding to the first and second reference signal resources is 2; conversely, if the fourth information is 0, it indicates that the number of panels corresponding to the first and second reference signal resources is 1.

[0163] The second possible implementation, taking the agreement between the terminal device and the network device on L2 second parameters, with each second parameter indicating one or more maximum transmission ports, as an example, involves using panel information to indicate one of the L2 second parameters, thereby indicating at least one of information one, information two, and information three. For example, the panel information can be one of the L2 second parameters, or it can be an index of one of the L2 second parameters.

[0164] In this implementation, when the panel information is used to indicate one of the second parameters of L2, it is equivalent to the panel information being used to indicate one or more maximum transmission ports.

[0165] When the panel information indicates a maximum number of transmission ports, the maximum number of transmission ports of the panel corresponding to the first reference signal resource and the maximum number of transmission ports of the panel corresponding to the second reference signal resource in the resource group corresponding to the panel information are equal and equal to the maximum number of transmission ports indicated by the second parameter indicated by the panel information. The first reference signal resource and the second reference signal resource in the resource group corresponding to the panel information correspond to the same panel. When the panel information indicates multiple maximum transmission port numbers, the maximum transmission port number of the panel corresponding to the first reference signal resource and the maximum transmission port number of the panel corresponding to the second reference signal resource are two of the multiple maximum transmission port numbers. The first reference signal resource and the second reference signal resource in the resource group corresponding to the panel information correspond to different panels.

[0166] For example, suppose there are 6 second parameters, and the correspondence between the second parameters and the index can be shown in Table 15.

[0167] Table 15

[0168] Referring to Table 15, if the panel information is 001, the second parameter indicated by the panel information is {2}, which indicates a maximum number of transmission ports of 2. If a resource group includes two reference signal resources, namely the first reference signal resource and the second reference signal resource, then the maximum number of transmission ports of the panel corresponding to the first reference signal resource in the resource group corresponding to this panel information is 2, the maximum number of transmission ports of the panel corresponding to the second reference signal resource is 2, and the first and second reference signal resources correspond to the same panel, that is, the number of panels corresponding to the first and second reference signal resources is 1. If the panel information is 011, the second parameter indicated by the panel information is {2, 2}, which indicates two maximum number of transmission ports of 2 and 2 respectively, meaning that the maximum number of transmission ports of the panel corresponding to the first reference signal resource in the resource group corresponding to this panel information is 2, the maximum number of transmission ports of the panel corresponding to the second reference signal resource is 2, but the first and second reference signal resources correspond to different panels, that is, the number of panels corresponding to the first and second reference signal resources is 2. Other cases can be deduced similarly and will not be elaborated further.

[0169] The above example uses the panel information as the second parameter index, but panel information can also be the second parameter. For example, referring to Table 15, if the panel information is {2}, the maximum number of transmission ports indicated by this panel information is 2. Then, the maximum number of transmission ports of the panel corresponding to the first reference signal resource in the resource group corresponding to this panel information is 2, the maximum number of transmission ports of the panel corresponding to the second reference signal resource is 2, and the first and second reference signal resources correspond to the same panel, that is, the number of panels corresponding to the first and second reference signal resources is 1. If the panel information is {2, 2}, the two maximum number of transmission ports indicated by this panel information are 2 and 2 respectively, indicating that the maximum number of transmission ports of the panel corresponding to the first reference signal resource in the resource group corresponding to this panel information is 2, the maximum number of transmission ports of the panel corresponding to the second reference signal resource is 2, but the first and second reference signal resources correspond to different panels, that is, the number of panels corresponding to the first and second reference signal resources is 2. Other cases can be deduced by analogy, and will not be elaborated further.

[0170] Furthermore, if the maximum number of transmission ports reported by the terminal device is greater than 0, then the panel information is also used to indicate whether one or two panels corresponding to the two reference signal resources in the resource group corresponding to the panel information can be used for uplink transmission, uplink multi-beam simultaneous transmission, or uplink multi-panel simultaneous transmission. For example, referring to Table 15, when the panel information is 000~101, it is used to indicate a second parameter; when the panel information is one of 110~111, at least one of the two reference signal resources in the resource group corresponding to the panel information may have a maximum number of transmission ports of 0, and cannot be used for uplink simultaneous transmission. In this case, if the panel information is one of 110~111, it means that one or two panels corresponding to the two reference signal resources in the resource group corresponding to the panel information cannot be used for uplink transmission, uplink multi-beam simultaneous transmission, or uplink multi-panel simultaneous transmission.

[0171] Furthermore, if each second parameter is used to indicate one or more maximum transmit ports and the number of panels corresponding to those maximum transmit ports, then in this implementation, when the panel information is used to indicate one of the L2 second parameters, it is equivalent to the panel information being used to indicate one or more maximum transmit ports and the number of panels corresponding to those maximum transmit ports. In this case, the number of panels corresponding to the X reference signal resources in the resource group corresponding to the panel information is equal to the number of panels indicated by the panel information.

[0172] For example, suppose there are 6 second parameters, and the correspondence between the second parameters and the index can be shown in Table 16.

[0173] Table 16

[0174] Referring to Table 16, if the panel information is 001, the second parameter indicated by the panel information is {2, 1}, which indicates a maximum number of transmitting ports of 2 and a panel count of 1. If a resource group includes two reference signal resources, namely a first reference signal resource and a second reference signal resource, then the maximum number of transmitting ports of the panel corresponding to the first reference signal resource in the resource group corresponding to this panel information is 2, the maximum number of transmitting ports of the panel corresponding to the second reference signal resource is 2, and the first and second reference signal resources correspond to the same panel, so the panel count corresponding to the first and second reference signal resources is 1. If the panel information is 011, the second parameter indicated by the panel information is {2, 2, 2}, which indicates two maximum number of transmitting ports of 2 and 2, and a panel count of 2. This means that the maximum number of transmitting ports of the panel corresponding to the first reference signal resource in the resource group corresponding to this panel information is 2, the maximum number of transmitting ports of the panel corresponding to the second reference signal resource is 2, but the first and second reference signal resources correspond to different panels, i.e., the panel count corresponding to the first and second reference signal resources is 2. Other cases can be deduced similarly and will not be elaborated further.

[0175] The example above uses the panel information as the second parameter index. Panel information can also be the second parameter. For example, referring to Table 16, if the panel information is {2, 1}, the maximum number of transmission ports indicated by this panel information is 2. Then, the maximum number of transmission ports for the panel corresponding to the first reference signal resource in the resource group corresponding to this panel information is 2, the maximum number of transmission ports for the panel corresponding to the second reference signal resource is 2, and the first and second reference signal resources correspond to the same panel, meaning the number of panels corresponding to the first and second reference signal resources is 1. If the panel information is {2, 2, 1}, the two maximum transmission port numbers indicated by this panel information are 2 and 2 respectively, indicating that the maximum number of transmission ports for the panel corresponding to the first reference signal resource in the resource group corresponding to this panel information is 2, the maximum number of transmission ports for the panel corresponding to the second reference signal resource is 2, but the first and second reference signal resources correspond to different panels, meaning the number of panels corresponding to the first and second reference signal resources is 2. Other cases can be deduced similarly and will not be elaborated further.

[0176] Furthermore, if the maximum number of transmission ports reported by the terminal device is greater than 0, then the panel information is also used to indicate whether one or two panels corresponding to the two reference signal resources in the resource group corresponding to the panel information can be used for uplink transmission, uplink multi-beam simultaneous transmission, or uplink multi-panel simultaneous transmission. For example, referring to Table 16, when the panel information is 000~101, it is used to indicate a second parameter; when the panel information is one of 110~111, at least one of the two reference signal resources in the resource group corresponding to the panel information may have a maximum number of transmission ports of 0, and cannot be used for uplink simultaneous transmission. In this case, if the panel information is one of 110~111, it means that one or two panels corresponding to the two reference signal resources in the resource group corresponding to the panel information cannot be used for uplink transmission, uplink multi-beam simultaneous transmission, or uplink multi-panel simultaneous transmission.

[0177] Optionally, after the network device obtains the first and second indication information, if it schedules the terminal device to perform simultaneous uplink transmission, then the two uplink beams transmitted by the terminal device need to correspond to two different panels. The network device can determine which resource groups correspond to the two panels based on the panel information associated with the resource groups reported by the terminal device, and then send an uplink transmission beam indication to the terminal device. This uplink transmission beam indication includes the reference signal resources for the two uplink transmission beams of the terminal device's simultaneous uplink transmission. These two reference signal resources come from one resource group and correspond to two different panels.
