[0080] In the related art, the CSI feedback reporting framework is an important component of the new radio (NR) of the fifth generation mobile communication technology (5G), which allows the UE to report channel state information to the next generation base station (gNB) for effective beam management and channel-dependent scheduling operations. For example, the channel state information reference signal (CSI-RS) can be used for beam management. The CSI feedback process is mainly divided into two steps: one is CSI resource configuration, and the gNB sends CSI-RS and / or synchronization signal block (SSB) to the UE according to the configuration; the other is CSI report configuration, and the UE measures the CSI-RS and / or demodulation reference signal (DM-RS) (located on the physical broadcast channel (PBCH) of the SSB), and then reports the CSI to the gNB according to the configuration. Among them, beam management refers to adjusting the amplitude and phase of the antenna through beamforming technology to concentrate the signal energy in a narrow beam in a specific direction, thereby enhancing the beam coverage and reducing interference. The process of beam management mainly includes: scanning, gNB sends multiple beams in different spatial directions, and UE monitors / scans these beams in different receiving spaces; evaluation, UE evaluates the received signal quality of each beam, and the evaluation indicators can include the reference signal received power (RSRP, Reference Signal Receiving Power) and signal to interference plus noise ratio (SINR, Signal to Interference plus Noise Ratio) of CSI-RS; reporting, UE reports beam quality and decision information to gNB; adjusting beam, the network can decide to adjust the current beam based on the beam measurement results reported by the UE.

[0081] In traditional beam management, the main focus is on beam measurement and reporting at the Layer 1 (L1) level of the gNB configuration. Specifically, the gNB can set or enable periodic or semi-persistent (P / SP) beam reports, for example, reporting N optimal beams and the L1 RSRP values ​​corresponding to the N optimal beams. In addition, the gNB can also trigger aperiodic (AP) beam reports to quickly capture the optimal beam for data or control channel transmission. However, on the one hand, this frequent beam report configuration undoubtedly increases the uplink reporting burden and control signaling overhead; on the other hand, if the beam report is configured or triggered at a low frequency, the UE's beam report may be outdated, that is, the gNB may not be able to continuously obtain the optimal beam, which will result in a significant decrease in beam performance and coverage, as well as increased delays in beam measurement reports.

[0082] Considering that the traditional beam measurement and reporting configuration framework has large overhead and delay, the relevant technology proposes to further enhance the UE-initiated or event-driven beam management process to reduce the overhead and delay of beam management. By enhancing the UE-initiated or event-driven beam management method, on the one hand, if the UE has a better and more timely understanding of the beam quality changes, the beam reporting process initiated by the UE will obtain more timely beam reports while reducing the reporting overhead; on the other hand, if the UE determines that the current beam quality has changed, for example, the current beam quality has deteriorated, then the UE can trigger the beam report without the network configuration or triggering frequent reports.

[0083] According to the current discussion on UE-initiated beam management in the relevant technology, it is agreed to trigger UE-initiated beam reporting (UEI reporting, UE-initiated reporting) through Mode A and Mode B based on uplink control information (UCI, Uplink Data Compression). Both Mode A and Mode B support cross-CC reporting:

[0084] For Mode A (dynamic scheduling of UCI by gNB): First, the UE sends the first physical uplink control channel (PUCCH, Physical Uplink Control Channel) (1 bit or multiple bits) to request the resources of the second uplink (UL, UplinkLink) channel to carry the beam report; then, the UE detects the downlink control information (DCI, Downlink ControlInformation) format, and the DCI format indicates the use of the resources of the second UL channel to carry the beam report; finally, the UE sends the beam report in the second UL channel. For Mode B (UCI in the pre-configured resources of the second UL channel): First, the UE sends the first PUCCH (1 bit or multiple bits) to notify the use of the second UL channel to carry the beam report; then, the UE sends the beam report in the second UL channel.

[0085] For the CA scenario, a UE can be connected to one PCell and multiple SCells, which together form the UE's serving cell set. Among them, PCell is the cell where the UE establishes the initial connection, which is mainly responsible for carrying signaling and managing other auxiliary carriers (SCells) added through carrier aggregation technology. PCell is indicated as the primary cell during the connection establishment and switching process, and is responsible for the radio resource control (RRC) communication between the UE. SCell is the auxiliary carrier in carrier aggregation technology, which is used to expand bandwidth and increase data transmission rate. SCell is configured after the RRC connection is established and added through RRC reconfiguration messages to provide additional wireless resources. Component carrier (CC) is a basic unit in carrier aggregation. Each CC can be regarded as an independent frequency block or channel with its own radio resources. In carrier aggregation technology, multiple CCs can be combined to form a wider frequency band to increase data transmission rate. In short, PCell and SCell are cells that provide services when the UE connects to the network, and CC is the carrier unit that constitutes these cells. Through carrier aggregation technology, multiple CCs can be aggregated together, managed by PCell, and the transmission capability can be expanded through SCell.

[0086] However, it has not yet been considered how the UE can use Mode A and Mode B to initiate beam reporting (UE-initiated reporting, UEI reporting) on ​​PCell and SCell (cross-CC) in the CA scenario; for example, in the cross-CC scenario of CA, when the current serving beam drops below a set threshold, the UE sends a request and the subsequent UE reports a beam report that fails. How to send signaling through other CCs becomes an urgent problem to be solved.

[0087] Based on this, in various embodiments of the present application, the terminal sends first information on the second SCell or PCell of the terminal when one or more first SCells of the terminal meet the set conditions; the network device receives the first information on the second SCell or PCell of the terminal; wherein the first information is sent when one or more first SCells of the terminal meet the set conditions, and includes at least one beam report of the first SCell; the second SCell is the same as or different from the first SCell. In the above scheme, the terminal sends the first information on the second SCell or PCell, thereby realizing that the UE initiates a beam report in the carrier aggregation scenario.

[0088] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0089] The present application embodiment provides an information transmission method, which is applied to a terminal, also called a user equipment (UE, UserEquipment), such as Figure 1 As shown, the method includes:

[0090] When one or more first SCells of the terminal meet a set condition, the first information is sent in the second SCell or PCell of the terminal; wherein,

[0091] The second SCell is the same as or different from the first SCell, and the first information includes at least a beam report of the first SCell.

[0092] Here, satisfying the set condition can be understood as triggering the beam initiation process, and the set condition indicates that the signal quality (such as L1-RSRP) of the current service beam on the first SCell drops below the first threshold, that is, less than or equal to the first threshold, and the terminal fails to send information or beam report on the first SCell, and needs to send information or report beam report on other cells or uplink resources; or, the set condition indicates that there is signal quality in one or more beams on the first SCell, and the difference with the signal quality of the current service beam is greater than or equal to the second threshold, and the first SCell needs to report a beam report; or the set condition indicates that there is signal quality in one or more beams on the first SCell, and the difference with the Mth best signal quality in the activated transmission configuration indication state (TCI state, Transmission Configuration Indicator state) is greater than or equal to the third threshold. Based on this, when one or more first SCells of the terminal meet the set condition, the first information is sent in the second SCell or PCell of the terminal.

[0093] It should be noted that, when a first SCell of the terminal meets the set conditions, the first information includes a beam report of the first SCell; when multiple first SCells of the terminal meet the set conditions, the first information includes beam reports of the multiple first SCells.

[0094] In order to implement beam reporting in a carrier aggregation scenario, in one embodiment, sending the first information on the second SCell or PCell includes:

[0095] The first information is sent on a first resource of the second SCell or the PCell; the first resource represents an uplink resource allocated by a network device to the second SCell, or an uplink resource reserved on the second SCell or the PCell.

[0096] Here, when one or more first SCells of the terminal meet the set conditions, the first information can be sent on the uplink resources allocated by the network device for the second SCell; the first information can also be sent on the uplink resources reserved on the second SCell or PCell. For example, when the beam report is initiated using the above-mentioned ModeA method, the first information is sent on the uplink resources allocated by the network device for the second SCell; when the beam report is initiated using the above-mentioned ModeB method, the first information is sent on the uplink resources reserved on the second SCell or PCell; the uplink resources can be understood as the physical uplink shared channel (PUSCH, Physical Uplink Shared Channel).

[0097] In order to initiate a beam reporting process in a carrier aggregation scenario, save signaling overhead, and improve beam reporting efficiency, in one embodiment, the method further includes:

[0098] Receive second information sent by a network device, wherein the second information indicates an association between the SCell of the terminal and uplink resources and / or third information, the uplink resources are used to feedback the first information, the third information is used to indicate that the first SCell needs to send the first information, and / or the network device receives the first information on the uplink resources reserved on the second SCell or the PCell.

[0099] Here, before the second SCell or PCell of the terminal sends the first information, the second information sent by the network device can be received; the second information can indicate the association between the SCell of the terminal and the third information, that is, each SCell of the terminal can be bound to a corresponding third information; the second information can also indicate the association between the SCell of the terminal and the uplink resources, that is, each SCell of the terminal has corresponding reserved uplink resources on the second SCell or PCell; the third information can be understood as a scheduling request (SR, Scheduling Request) or UCI.

[0100] In order to improve the efficiency of beam reporting, or to initiate beam reporting on PCell and SCell based on Mode B, in one embodiment, the second information indicates one or more of the following:

[0101] an association relationship between an identifier of each SCell of the terminal and an identifier of the third information;

[0102] The same uplink resources reserved on the PCell for all SCells of the terminal;

[0103] Uplink resources reserved on each SCell of the terminal;

[0104] Uplink resources reserved on the PCell;

[0105] When any SCell of the terminal meets a set condition, sending first information using uplink resources reserved on another SCell;

[0106] The first identifier and the second identifier are associated with the third information, the first identifier indicates that the third information is sent on the PCell of the terminal when the SCell corresponding to the first identifier meets the set conditions, and the second identifier indicates that the first information of the SCell corresponding to the first identifier is sent on the reserved uplink resources of the SCell corresponding to the second identifier.

[0107] Here, the second information can indicate the association between the identifier of each SCell of the terminal and the identifier of the third information. The identifier of the SCell corresponds one-to-one to the identifier of the third information. Therefore, when one or more first SCells meet the set conditions, the third information corresponding to the first SCell can be directly sent without configuring the third information for the first SCell, so as to improve the information transmission efficiency of initiating the beam reporting process.

[0108] When one or more first SCells of the terminal meet the set conditions and the beam report is initiated in Mode B, the second information may also indicate any one or more of the following; when the second information indicates any one of the following, the first information is sent based on the second information; when the second information indicates any one of the following, the first information may be sent based on one of the following:

[0109] The same uplink resources are reserved on the PCell for all SCells of the terminal;

[0110] Uplink resources reserved on each SCell of the terminal;

[0111] Uplink resources reserved on PCell;

[0112] When any SCell of the terminal meets a set condition, the first information is sent using uplink resources reserved on another SCell.

[0113] Among them, when the second information can indicate the same uplink resources reserved on the PCell for all SCells of the terminal, and a first SCell of the terminal meets the set conditions, the first information can be sent on the uplink resources reserved on the PCell of the terminal, and the first information includes a beam report of the first SCell. When the second information can indicate the uplink resources reserved on each SCell of the terminal, and a first SCell of the terminal meets the set conditions, the first information can be sent on the uplink resources reserved on the first SCell. At this time, the first SCell is the same as the second SCell, and the first information includes a beam report of the first SCell. When the second information can indicate the uplink resources reserved on the PCell, and multiple first SCells of the terminal meet the set conditions, the terminal can send the first information on the uplink resources reserved on the PCell, and the first information includes beam reports of the multiple first SCells. When the second information can indicate that the first information is sent on the uplink resources reserved on another SCell when any SCell of the terminal meets the set conditions, the first SCell is different from the second SCell. At this time, the second information can also indicate the first identifier and the second identifier associated with the third information, wherein the first identifier can be understood as the identifier of the SCell (first SCell) that meets the set conditions, and the second identifier can be understood as the identifier of the other SCell (second SCell).

[0114] It should be noted that the second information may also only indicate the first identifier and the second identifier associated with the third information, indicating that when the signal quality of the service beam of the SCell corresponding to the first identifier meets the set conditions, the terminal sends the third information on the PCell of the terminal to notify the network device to receive the first information of the SCell corresponding to the first identifier on the reserved uplink resources of the SCell corresponding to the second identifier. The first identifier and the second identifier associated with the third information can also be understood as: when the SCell corresponding to the first identifier meets the set conditions, an uplink resource is specified for the first information of the SCell corresponding to the first identifier, and the uplink resource is the uplink resource reserved on the SCell corresponding to the second identifier. The third information is bound to the first identifier and the second identifier, and the third information corresponds one-to-one with the first identifier; the first identifier can be understood as the identifier of the above-mentioned first SCell.

[0115] In this embodiment, when one or more first SCells of the terminal meet the set conditions, the terminal uses the uplink resources reserved on the PCell or the second SCell to send the first information, that is, the terminal can send the first information across CCs, thereby initiating beam reporting on the PCell and SCell (across CCs) using Mode B.

[0116] In order for the terminal to initiate a beam reporting process, report the beam report in time and reduce signaling overhead, in one embodiment, the method further includes:

[0117] Sending third information corresponding to the first SCell on the PCell; the third information indicates that the first SCell needs to send first information and / or the network device receives first information on a first resource, and the first resource represents an uplink resource reserved on the second SCell or the PCell.

[0118] Here, when one or more first SCells of the terminal meet the set conditions, the third information corresponding to the first SCell can be sent on the PCell first, and the identifier of the third information can be bound one-to-one with the identifier of one SCell, or can be bound with the identifier of the first SCell (first identifier) ​​and the identifier of the second SCell (second identifier). When the beam report is initiated using Mode A, the third information can indicate that the first SCell needs to send the first information; when the beam report is initiated using Mode B, the third information can indicate that the network device receives the first information on the first resource, and can also indicate that the first SCell needs to send the first information.

[0119] It should be noted that the third information may also indicate that the first SCell meets the set condition. In addition, the PCell is responsible for the communication of the control plane, including the sending and management of the SR. Therefore, when the third information is the SR, the third information is usually sent on the PCell. In the case where there is an SCell configured with PUCCH, the third information corresponding to the SCell belonging to the same PUCCH group as the SCell may also be sent on the SCell configured with PUCCH.

[0120] It should be noted that, when multiple first SCells of the terminal meet the set conditions, the third information corresponding to any first SCell among the multiple first SCells can be sent.

[0121] In order to obtain the uplink resources allocated by the network device so as to initiate a beam report on the SCell based on Mode A, in one embodiment, after sending the third information corresponding to the first SCell on the PCell, the method further includes:

[0122] Receive fourth information sent by a network device; the fourth information is used to indicate the uplink resources allocated by the network device to the second SCell.

[0123] Here, the third information indicates that the first SCell needs to send the first information, that is, notifies the network device to allocate uplink resources for the terminal for sending the first information of the first SCell. The fourth information may be DCI. In the case of receiving the fourth information sent by the network device, the uplink resources allocated by the network device for sending the first information, that is, the uplink resources on the second SCell, are determined based on the fourth information; and the first information is sent on the uplink resources of the second SCell allocated by the network device.

[0124] In order to initiate beam reporting on the SCell in a carrier aggregation scenario, in one embodiment, the second SCell includes one or more of the following:

[0125] Any SCell different from the first SCell;

[0126] the first SCell;

[0127] Any first SCell among multiple first SCells of the terminal;

[0128] The SCell associated with the third information sent by the terminal;

[0129] An SCell associated with an uplink resource used to transmit the first information;

[0130] The next SCell adjacent to the first SCell in the SCell sequence; the SCell sequence is arranged in ascending order according to the SCell identifier;

[0131] The network device configures the first SCell as an SCell for sending the first information.

[0132] Here, in the case where the second SCell includes any SCell different from the first SCell, it may be that when the beam report is initiated using ModeA, the network device allocates uplink resources on any SCell different from the first SCell, and the uplink resources are used to send the first information; it may also be that when the beam report is initiated using ModeB, uplink resources are reserved for the first SCell on another SCell, and the uplink resources are used to send the first information. In the case where the second SCell includes the first SCell, it may be that when the beam report is initiated using ModeA, the network device allocates uplink resources on the first SCell, and the uplink resources are used to send the first information; it may also be that when the beam report is initiated using ModeB, uplink resources are reserved on the first SCell, and the uplink resources are used to send the first information. In the case where the second SCell includes any first SCell among multiple first SCells of the terminal, it may be that when the beam report is initiated using ModeA and the multiple first SCells meet the set conditions, the network device allocates uplink resources on any first SCell among the multiple first SCells. In the case where the second SCell includes an SCell associated with the third information sent by the terminal, or an SCell associated with the uplink resources for transmitting the first information, when the beam report is initiated using ModeB, the identifier of the first SCell (first identifier) ​​and the identifier of the second SCell (second identifier) ​​are associated with the third information, that is, the uplink resources reserved on the SCell corresponding to the second identifier associated with the third information are used to transmit the first information. In the case where the second SCell includes the next SCell adjacent to the first SCell in the SCell sequence, it can be predefined in the protocol: when the beam report is initiated using ModeB, the identifiers of all working SCells are arranged in ascending order, and the next SCell adjacent to the first SCell in the obtained SCell sequence is used as the second SCell. In the case where the second SCell includes the SCell configured by the network device for the first SCell to send the first information, the beam report can be initiated using ModeB, and the SCell configured by the network device for the first SCell to send the first information is used as the second SCell.

[0133] In summary, when the beam report is initiated based on Mode A, the second SCell may include any of the following:

[0134] Any SCell different from the first SCell;

[0135] First SCell;

[0136] Any first SCell among multiple first SCells of the terminal.

[0142] The next SCell adjacent to the first SCell in the SCell sequence;

[0143] The network device configures the first SCell for sending the first information.

[0144] In order to enable the network device to accurately determine the SCell corresponding to the beam report, in one embodiment, the first information also includes an identifier of each first SCell and the corresponding CSI.

[0145] Here, when multiple first SCells of the terminal meet the set conditions, the first information includes beam reports of multiple first SCells, and may also include identifiers of each first SCell in the multiple SCells and the corresponding CSI. That is, the first information may include the association between the identifier of the first SCell and the beam report and CSI of the first SCell; the CSI includes CSI reference signal (CSI-RS, CSI Reference Signal) resource indicator (CRI, CSI-RS Resource Indicator), L1-RSRP and other information.

[0146] The present application embodiment provides an information transmission method, which is applied to a network device, wherein the network device includes a base station, such as Figure 2 As shown, the method includes:

[0147] Step 201: Receive first information on a second SCell or PCell of a terminal.

[0148] The first information is sent when one or more first SCells of the terminal meet the set conditions, and includes at least a beam report of a first SCell; the second SCell is the same as or different from the first SCell.

[0149] Here, the first information is received on the second SCell or PCell of the terminal. For example, when the terminal uses ModeA to initiate beam reporting, the first information is received on the uplink resources reserved for the second SCell or PCell of the terminal; when the terminal uses ModeB to initiate beam reporting, the first information is received on the uplink resources allocated to the second SCell.

[0151] First information is received on a first resource of the second SCell or the PCell of the terminal; the first resource represents an uplink resource allocated by the network device to the second SCell, or an uplink resource reserved on the second SCell or the PCell.

[0152] Here, the first information is received on the first resource of the second SCell or PCell of the terminal. For example, when the beam report is initiated using Mode A, the network device allocates uplink resources to the second SCell, that is, schedules uplink resources for the terminal to send the first information on any SCell, and receives the first information on the first resource of the second SCell of the terminal; when the beam report is initiated using Mode B, the network device receives the first information on the first resource of the second SCell or PCell notified by the terminal.

[0153] In order to enable the terminal to initiate a beam report in a carrier aggregation scenario, save signaling overhead, and improve the efficiency of beam report reporting, in one embodiment, the method further includes:

[0154] Sending second information to the terminal, the second information indicating an association between the SCell of the terminal and uplink resources and / or third information, the uplink resources are used to feedback the first information, the third information is used to indicate that the first SCell needs to send the first information, and / or the network device receives the first information on the uplink resources reserved on the second SCell or the PCell.

[0155] Here, the network device can configure the terminal so that the terminal can initiate a beam report in a carrier aggregation scenario; for example, the network device can bind each SCell of the terminal to the third information. For the scheme of initiating beam reporting based on Mode B, the network device can reserve an uplink resource on the second SCell or PCell for each SCell of the terminal, that is, each SCell of the terminal is associated with an uplink resource on the second SCell or PCell; based on this, the network device sends the second information to the terminal; the third information can be SR or UCI.

[0156] In order to improve the efficiency of beam reporting, or to enable the terminal to initiate beam reporting on the PCell and SCell based on Mode B, in one embodiment, the second information indicates one or more of the following:

[0160] Uplink resources reserved on the PCell;

[0161] When any SCell of the terminal meets a set condition, sending first information using uplink resources reserved on another SCell;

[0162] The first identifier and the second identifier are associated with the third information, the first identifier indicates that the third information is sent on the PCell of the terminal when the SCell corresponding to the first identifier meets the set conditions, and the second identifier indicates that the first information of the SCell corresponding to the first identifier is sent on the reserved uplink resources of the SCell corresponding to the second identifier.

[0163] Here, the SCell and the third information may be bound one by one to improve the efficiency of beam reporting, that is, the second information may indicate the association between the identifier of each SCell of the terminal and the identifier of the third information. Uplink resources may also be configured for the terminal so that the terminal can initiate a beam report based on Mode B, that is, the second information may also indicate one or more of the following:

[0164] The same uplink resources are reserved on the PCell for all SCells of the terminal;

[0165] Uplink resources reserved on each SCell of the terminal;

[0166] Uplink resources reserved on PCell;

[0167] When any SCell of the terminal meets a set condition, sending first information using uplink resources reserved on another SCell;

[0168] The third information is associated with the first identifier and the second identifier.

[0169] In order to enable the terminal to successfully complete the beam reporting, in one embodiment, the method further includes:

[0170] The third information corresponding to the first SCell is received on the PCell; the third information indicates that the first SCell needs to send the first information and / or the network device receives the first information on the first resource, and the first resource represents the uplink resource reserved on the second SCell or the PCell.

[0171] Here, before receiving the first information sent by the terminal, the third information corresponding to the first SCell can be received on the PCell first. There is an uplink resource on the PCell for transmitting the third information, and the third information corresponding to the first SCell is received on the uplink resource. When the third information only indicates that the first SCell needs to send the first information (for example, the terminal initiates a beam report using Mode A), an uplink resource is allocated to the terminal on the second SCell for the terminal to send the first information of the first SCell, and the second SCell is any SCell; when the third information indicates that the network device receives the first information on the first resource (for example, the terminal initiates a beam report using Mode B), the network device receives the first information on the first resource indicated by the third information.

[0172] In order to enable the terminal to initiate a beam report on the SCell based on Mode A, in one embodiment, after receiving the third information corresponding to the first SCell on the PCell of the terminal, the method further includes:

[0173] Allocate uplink resources to the second SCell based on the third information;

[0174] Send fourth information to the terminal, where the fourth information is used to indicate the uplink resources allocated by the network device to the second SCell.

[0175] Here, after receiving the third information corresponding to the first SCell on the PCell of the terminal, and the third information indicates that the first SCell needs to send the first information, the network device allocates uplink resources for the first information of the first SCell of the terminal on any SCell, that is, allocates uplink resources to the second SCell; and sends fourth information to the terminal to indicate the uplink resources of the second SCell allocated for the first information of the first SCell indicated by the third information.

[0183] The network device is an SCell configured for the first SCell for sending first information.

[0184] Here, the network device allocates uplink resources of the second SCell to the terminal based on the received third information, or reserves uplink resources of the second SCell for the terminal. For example, when the third information indicates that the first SCell needs to send the first information, the uplink resources of the second SCell are allocated to the terminal, so that the terminal can initiate a beam report based on Mode A. The second SCell may include any of the following:

[0185] Any SCell different from the first SCell;

[0186] First SCell;

[0187] Any first SCell among multiple first SCells of the terminal.

[0189] For another example, when the third information indicates that the network device receives the first information on the first resource, an uplink resource is reserved for each SCell of the terminal, so that the terminal can initiate a beam report on the SCell based on Mode B. The second SCell may include one or more of the following:

[0197] The present application is further described in detail below with reference to the application examples for Mode A and Mode B respectively.

[0198] For Mode A:

[0199] Step 1: The network device sends second information to the terminal.

[0200] Here, the network device pre-binds each SCell with a third information, determines the second information, and sends the second information to the terminal, where the second information indicates the association between the identifier of each SCell of the terminal and the identifier of the third information.

[0201] Step 2: When one or more first SCells of the terminal meet the set conditions, third information corresponding to the first SCell is sent on the PCell.

[0202] Here, when a first SCell of the terminal meets the set conditions, the third information corresponding to the first SCell is sent on the PCell; when multiple first SCells of the terminal meet the set conditions, the third information corresponding to any first SCell is sent on the PCell; the third information indicates that the first SCell needs to send the first information. For example, when SCell1 meets the set conditions, the third information corresponding to SCell1 is sent on the PCell.

[0203] Step 3: The terminal receives the fourth information sent by the network device.

[0204] Here, after receiving the third information corresponding to the first SCell on the PCell, the network device schedules an uplink resource on any SCell based on the third information, that is, allocates an uplink resource to the second SCell, determines the fourth information, and sends the fourth information to the terminal; the terminal receives the fourth information sent by the network device. For example, the network device can schedule an uplink resource on SCell 1, and can also schedule an uplink resource on SCell 2.

[0205] Step 4: The terminal sends the first information in the second SCell of the terminal.

[0206] Here, upon receiving the fourth information sent by the network device, the terminal sends the first information on the uplink resources allocated to the second SCell by the network device indicated by the fourth information.

[0207] For Mode B:

[0208] Step 1: The network device sends second information to the terminal.

[0209] Here, the network device pre-binds each SCell with a third information one by one, or associates the third information with the first identifier and the second identifier; the network device may also reserve an uplink resource for each SCell on the second SCell or PCell; and sends second information to the terminal, the second information indicating the association relationship between the identifier of each SCell of the terminal and the identifier of the third information, or the first identifier and the second identifier associated with the third information, and the second information further indicates any of the following:

[0210] The same uplink resources reserved on the PCell for all SCells of the terminal;

[0211] Uplink resources reserved on each SCell of the terminal;

[0212] Uplink resources reserved on the PCell;

[0213] When any SCell of the terminal meets a set condition, the first information is sent using uplink resources reserved on another SCell.

[0214] Step 2: When one or more first SCells of the terminal meet the set conditions, third information corresponding to the first SCell is sent on the PCell.

[0216] Step 3: The terminal sends the first information in the second SCell or PCell of the terminal.

[0217] Here, when the second information indicates the same uplink resource reserved on the PCell for all SCells of the terminal, or the uplink resource reserved on the PCell, the terminal sends the first information on the uplink resource reserved on the PCell, and the first resource in step 2 is also the uplink resource reserved on the PCell. When the second information indicates the uplink resource reserved on each SCell of the terminal, the terminal sends the first information on the uplink resource reserved on the first SCell, and the first resource in step 2 is the uplink resource reserved on the first SCell, and the first SCell is the same as the second SCell; for example, when the first SCell is SCell 1, the third information indicates that the network device receives the first information on the uplink resource reserved on SCell 1, and the terminal sends the first information on the uplink resource reserved on SCell 1; for another example, when the first SCell is SCell2, the third information indicates that the network device receives the first information on the uplink resource reserved on SCell 2, and the terminal sends the first information on the uplink resource reserved on SCell 2. In the case where the second information indicates the first identifier and the second identifier associated with the third information, the terminal sends the first information on the uplink resources reserved on the SCell corresponding to the second identifier, and the SCell corresponding to the first identifier can be understood as the first SCell; for example, the first SCell is SCell 1, and the SCell corresponding to the second identifier is SCell 2 or SCell 3. In the case where the second information indicates that the first information is sent on the uplink resources reserved on another SCell when any SCell of the terminal meets the set conditions, the terminal sends the first information on the uplink resources reserved on another SCell specified by the network device; wherein the other SCell specified by the network device can be the next SCell adjacent to the first SCell in the SCell sequence predefined in the protocol, and / or the SCell configured by the network device for the first SCell to send the first information.

[0218] It should be noted that in Mode A and Mode B, when the multiple first SCells of the terminal meet the set conditions, the first information includes beam reports of multiple first SCells, multiple first SCell identifiers and corresponding CSI, and the association between multiple first SCell identifiers and the beam reports of multiple first SCells and the corresponding CSI; the association between multiple first SCell identifiers and the beam reports of multiple first SCells and the corresponding CSI can also be included in the reporting format of the first information.
