Description

Reporting method, device and system of measurement result

[0001] The present application claims priority from a Chinese patent application filed on July 02, 2024, and assigned application number 202410882251.0, and having the title "Reporting method, device and system of measurement result", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, and more particularly, to a reporting method, device and system of measurement result. BACKGROUND

[0003] In wireless communication, in order to send and receive data, obtain system synchronization and feedback channel information, etc., reference signals will be transmitted between the sending end and the receiving end. For example, the sending end sends a reference signal to the receiving end, and the receiving end receives the reference signal, and then can perform corresponding operations based on the reference signal, such as performing channel measurement and reporting measurement report. At present, the reporting occasion of the measurement report is mainly determined by the network device, for example, in periodic and semi-persistent measurement reporting, the terminal device reports the measurement result once every period, and these measurement results may be meaningless to the network device, resulting in a large overhead of uplink resources. Therefore, designing an effective reporting method of measurement result is a problem that needs to be considered at present. SUMMARY

[0004] The present application provides a reporting method, device and system of measurement result, in order to support the reporting of measurement results related to events occurring on one or more cells.

[0005] In a first aspect, a reporting method of measurement result is provided. The method can be performed by a first device, and in the absence of special description, the "first device" in the present application can refer to the first device itself (for example, a terminal device), a component (for example, a communication module, a processor, a circuit, a chip, or a chip system, etc.) in the first device, or a logic module or software capable of realizing all or part of the functions of the first device.

[0006] The method includes: obtaining configuration information, the configuration information being used to indicate information of X events corresponding to (or associated with) M cells, M and X being integers greater than or equal to 1; and sending a measurement report, the measurement report including measurement results of at least one event related to M1 cells, the at least one event related to M1 cells being an event occurring in the X events, a load size of the measurement report being a load size required for reporting a first event and / or a measurement report result related to a first cell, the M1 cells belonging to the M cells, M1 being a positive integer less than or equal to M.

[0007] It can be understood that the load size of the measurement report refers to the load size included in the measurement report, or the number of bits / bit space / bit width included in the measurement report, or the space / reserved load size / bit number / bit space / bit width of the measurement report, and the like. That is, the space, reported space, bit space, reported bit space, load size, reported load size, bit number, reported bit number, bit width, reported bit width, reported payload size, or payload size in this application can be replaced with each other.

[0008] Optionally, the load size of the measurement report is the load size required for reporting the measurement report result related to the first event, or the load size required for reporting the measurement result related to the first cell, or the load size required for reporting the measurement result related to the first event and the first cell. It can be understood as the load size required for reporting the measurement result related to the first event associated with the first cell, or the load size required for reporting the measurement result corresponding to the first event occurred on the first cell.

[0009] Based on the above scheme, the terminal device can perform cross-cell event triggered reporting, so as to avoid the terminal device reporting invalid measurement reports to the network device, and can report meaningful measurement results (such as at least one event associated measurement result corresponding to M1 cells of the occurred event), and reduce the uplink resource overhead. In addition, the terminal device can define the load size of the measurement report, so as to avoid the resource waste caused by allocating corresponding reporting resources for each event when the terminal device supports or configures at least one event occurred on one or more cells, and to realize reasonable allocation of resources.

[0010] In a possible design, M1 is equal to 1, and the at least one event is one event.

[0011] That is, the number of cells on which the event occurs and / or the number of events that occur are not limited in this application, and the terminal device can select or determine one cell on which the event occurs to report, and / or can select one event to report, which is convenient for cell and event management and easier to implement.

[0012] In a possible design, the first event is the event with the largest load size in the load size required for reporting the measurement result related to X events, and the first cell is the cell with the largest load size in the load size required for reporting the measurement result related to M cells.

[0013] That is, the load size of the measurement report is the load size required for the measurement result related to the event with the largest load size in X events, or the load size required for the measurement result related to the cell with the largest load size in M cells.

[0014] In a possible design, the first cell is one of M cells, and the load size of the measurement report is a sum of load sizes required for reporting measurement results related to the M cells.

[0015] That is, the load size of the measurement report is a sum of load sizes required for reporting measurement results related to the M cells, which can achieve reasonable allocation of resources and ensure reporting of measurement results related to all occurred events to the network device.

[0016] In a possible design, a part of the measurement report other than the at least one event-related measurement result corresponding to the M1 cells is a predefined value, for example, all 0. That is, the part of the measurement report other than the at least one event-related measurement result corresponding to the M1 cells, i.e., the reporting position of measurement results corresponding to the M-M1 cells, can be filled with the predefined value.

[0017] In a possible design, the method further includes: sending first information, the first information being used to indicate information of each of the M1 cells, for example, an identifier of the cell; and / or a load size of the measurement report.

[0018] Optionally, the first information can be carried in scheduling request (SR) signaling or reporting indication signaling.

It can be understood that each event can be associated with one or more reporting quantities.

[0022] Optionally, the terminal device simultaneously sends at least one of the following through one information: information of each of the M1 cells, a required load size of at least one event-related measurement result corresponding to the M1 cells, information of at least one event corresponding to each of the M1 cells, or a reporting number of a reporting quantity corresponding to each of the at least one event, wherein each event can correspond to one or more reporting quantities.

[0024] Optionally, the second information can be carried in scheduling request (SR) message signaling or reporting indication signaling.

[0025] Optionally, the second information can further include at least one event-related measurement result corresponding to the M1 cells.

[0026] In a possible design, a required load size of reporting each cell-related measurement result in the M cells is determined according to a maximum event of a required load size of reporting a related measurement result in one or more events corresponding to each cell.

[0027] In a possible design, a required load size of reporting each cell-related measurement result in the M cells is determined according to a sum of required load sizes of reporting all event-related measurement results corresponding to each cell.

In other examples, a helicopter or unmanned aerial vehicle can be configured to act as a device that communicates with another base station.

[0187] In some deployments, the network device mentioned in the embodiments of the present application can be a device including a CU, or a DU, or a device including a CU and a DU, or a control plane CU node (central unit-control plane (CU-CP)) and a user plane CU node (central unit-user plane (CU-UP)) and a DU node. For example, the network device can include a gNB-CU-CP, a gNB-CU-UP and a gNB-DU.

[0188] In some deployments, a plurality of RAN nodes cooperate to assist a terminal to implement wireless access, and different RAN nodes respectively implement part of the functions of a base station. For example, the RAN node can be a CU, a DU, a CU-CP, a CU-UP, or a radio unit (RU) (or referred to as a radio frequency unit), etc. The CU and the DU can be separately arranged, or can also be included in the same network element, for example, in a BBU. The RU can be included in a radio frequency device or a radio frequency unit, for example, included in an RRU, an AAU or an RRH.

[0189] In some deployments, the CU is a logical node that hosts the RRC layer, service data adaptation protocol (SDAP) layer, packet data convergence protocol (PDCP) layer, and other control functions of the access network device. The CU connects with network nodes such as core network via some interfaces, which can be E2 interface, etc. Optionally, the CU has part of the functions of the core network. The CU (e.g., PDCP layer and higher) connects with the DU (e.g., radio link control (RLC) layer and lower) via some interfaces, which can be Fl interface, etc. In some examples, these interfaces (e.g., Fl interface) can provide control plane (C-Plane) and user plane (U-Plane) functions (e.g., interface management, system information management, UE context management, RRC message transfer, etc.). Fl application protocol (FlAP) is an application protocol of Fl interface, which defines the signaling procedures of Fl in some examples. The Fl interface supports control plane (Fl-C), user plane (Fl-U).

[0190] In some deployments, a CU can be split into a CU-CP and a CU-UP. The CU-CP is a logical node that carries the control plane part of PDCP (PDCP-C) layer and RRC layer, and is used to implement the control plane function of the CU. The CU-CP can interact with a network element in the core network that is used to implement the control plane function. The network element in the core network that is used to implement the control plane function can be an access and mobility function network element. The CU-UP is a logical node that carries the user plane part of PDCP (PDCP-U) layer and SDAP layer, and is used to implement the user plane function of the CU. The CU-UP can interact with a network element in the core network that is used to implement the user plane function. The network element in the core network that is used to implement the user plane function. The above configurations of the CU and the DU are merely examples, and the CU and the DU can have other functions according to needs. For example, the CU or the DU can be configured to have more protocol layer functions, or the CU or the DU can be configured to have partial processing functions of the protocol layers. For example, partial functions of the RLC layer and functions of the protocol layers above the RLC layer are arranged in the CU, and the remaining functions of the RLC layer and functions of the protocol layers below the RLC layer are arranged in the DU. For another example, the functions of the CU or the DU can be divided according to service types or other system requirements. For example, functions that need to meet a relatively short delay requirement in processing time are arranged in the DU, and functions that do not need to meet the delay requirement are arranged in the CU.

[0191] In some deployments, a DU is a logical node that carries an RLC layer, a medium access control (MAC) layer, a higher physical layer (Higher PHY), and other functions. In some examples, a DU can control at least one RU. The DU is connected to the RU through some interfaces, which can be a front-haul interface. In some examples, the Higher PHY layer includes part of the PHY layer processing, such as forward error correction (FEC) encoding and decoding, scrambling, modulation and demodulation, and other processing functions.

[0192] In some deployments, a RU is a logical node that hosts lower physical layer (Lower PHY) and radio frequency (RF) processing. In some examples, a RU can be a TRP or a RRH or other similar functional entity. In some examples, a Low-PHY includes portions of PHY processing such as fast Fourier transform (FFT), inverse fast Fourier transformation (IFFT), digital beamforming and filtering, and other processing functions. A RU communicates with one or more UEs over a wireless link.

[0193] A DU and a RU can or can not be co-located. A DU and a RU exchange control plane and user plane information over a fronthaul link via a lower-layer split-CUS-Plane (LLS-CUS) interface. The LLS-CUS can include interfaces and interfaces that provide control plane and user plane, respectively. In some examples, the control plane refers to real-time control between a DU and a RU. A DU and a RU have a LLS-M interface of the fronthaul link to exchange management information, and the management plane (M-Plane) refers to non-real-time management operations between a DU and a RU.

[0194] A DU and a RU can cooperate to collectively implement the functionality of a PHY layer. One DU can be connected to one or more RUs. The functionality that a DU and a RU have can be configured in multiple ways according to design. For example, a DU is configured to implement baseband functionality, and a RU is configured to implement mid- RF functionality. As another example, a DU is configured to implement high-layer functionality in a PHY layer, and a RU is configured to implement low-layer functionality in the PHY layer or to implement the low-layer functionality and RF functionality. The high-layer functionality in a PHY layer can include a portion of functionality of the PHY layer that is closer to a MAC layer, and the low-layer functionality in a PHY layer can include another portion of functionality of the PHY layer that is closer to a mid-RF side.

[0195] In one possible design, a processing unit in a BBU that implements baseband functionality is referred to as a base band high (BBH) unit, and a processing unit in a RRU / AAU / RRH that implements baseband functionality is referred to as a base band low (BBL) unit.

[0196] In different systems, the CU (including open CU-CP (O-CU-CP) and open CU-UP (O-CU-UP), DU or RU can also have different names, but those skilled in the art can understand their meanings. For example, in an open radio access network (O-RAN or ORAN) system, the CU can also be referred to as an open central unit (O-CU), the DU can also be referred to as an open distributed unit (O-DU), the CU-CP can also be referred to as an O-CU-CP, the CU-UP can also be referred to as an O-CU-UP, and the RU can also be referred to as an open radio unit (O-RU). For the convenience of description, the CU, CU-CP, CU-UP, DU and RU are taken as examples for description in this application. Any one of the CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0197] In the embodiments of the present application, the device for implementing the function of the network device can be a network device, or a device capable of supporting the network device to implement the function, such as a chip system or a chip or a circuit or a communication module (i.e., a communication module performing a communication function), which can be installed in the network device.

In addition, program instructions for performing corresponding communication functions can also be configured in the device. In the embodiments of the present application, only the device for implementing the function of the network device is taken as an example for description, and the scheme of the embodiments of the present application is not limited.

As shown in Figure 2, the wireless communication system can include core network devices, access network devices (e.g. RANs), terminal devices, the access network devices communicate with the core network devices over backhaul links, and communicate with the terminal devices over the air. For example, a BBU in the access network device communicates with the core network over a backhaul link, and a RU in the access network device communicates with the terminal devices over the air. The BBU can communicate with the RU over a front-haul link, and the BBU and the RU can or can not be co-located. In some deployments, the BBU includes at least one CU and at least one DU, and the CU and the DU can communicate with each other over a mid-haul link.

[0202] Figure 2 is a schematic diagram given for easy understanding, and the wireless communication system can further include other devices, which are not shown in Figure 2.

[0203] To facilitate understanding of the technical solutions of the present application, some related technologies involved in the technical solutions of the present application are introduced.

[0204] 1. Beam: a kind of communication resource. Different beams can be considered as different resources. The same information or different information can be transmitted through different beams.

[0205] The beam in the NR protocol can be a spatial domain filter, or a spatial filter or a spatial parameter, or a spatial domain parameter, a spatial parameter, a spatial domain setting, a spatial setting, or quasi-co-location (QCL) information, a QCL assumption, a QCL indication, etc. The beam can be indicated by a transmission configuration indicator (TCI)-state (TCI-state or TCIstate) parameter, or a spatial relation parameter. Therefore, in this application, the beam can be replaced by a spatial domain filter, a spatial filter, a spatial domain parameter, a spatial parameter, a spatial domain setting, a spatial setting, QCL information, a QCL assumption, a QCL indication, a TCI-state, a spatial relation, etc. The above terms are also equivalent to each other. The beam can also be replaced by other terms representing the beam, which are not limited in this application.

[0206] A beam used for transmitting a signal can be referred to as a transmission beam (Tx beam), a spatial domain transmission filter, a spatial transmission filter, a spatial domain transmission parameter or a spatial transmission parameter, a spatial domain transmission setting or a spatial transmission setting. A downlink transmission beam can be indicated by a TCI-state. A transmission beam can also be referred to as a downlink beam. In this application, a transmission beam, a downlink beam, a channel state information reference signal (CSI-RS), a TCI state, a downlink / joint transmission configuration indication state (DLorjointTCI state), a synchronization signal / physical broadcast channel block (SS / PBCH block, SSB for short), and a tracking reference signal (TRS) can be replaced with each other.

[0207] A beam for receiving a signal can be referred to as a reception beam (Rx beam), a spatial domain reception filter, a spatial reception filter, a spatial domain reception parameter or a spatial reception parameter, a spatial domain reception setting or a spatial reception setting. An uplink transmission beam can be indicated by a spatial relation, or an uplink TCI-state, or a sounding reference signal (SRS) resource (indicating a transmission beam using the SRS). Therefore, an uplink beam, an SRS resource, an uplink TCI-state can be replaced with each other. A reception beam can also be referred to as an uplink beam. In this application, a reception beam, an uplink beam, an uplink transmission configuration indication state (UL TCI state), a DL or joint TCI state, a sounding reference signal (SRS), a CSI-RS, an SSB, and a tracking reference signal (TRS) can be replaced with each other.

[0208] A transmission beam can refer to a distribution of signal strength in different directions in space after a signal is transmitted by an antenna, and a reception beam can refer to a distribution of signal strength in different directions in space of a wireless signal received by an antenna.

[0209] In addition, a beam can be a wide beam, or a narrow beam, or other types of beams. The technology for forming a beam can be beamforming technology or other technology. The beamforming technology can be digital beamforming technology, analog beamforming technology, or hybrid digital / analog beamforming technology, etc.

[0210] As an example, multiple beams with the same or similar communication characteristics can be considered as one beam.

[0211] A beam is generally associated with a resource, for example, when performing beam measurement, the network device measures different beams through different resources, and the terminal device feeds back the measured resource quality, so that the network device knows the quality of the corresponding beam.

[0212] Optionally, multiple beams with same or similar communication characteristics are regarded as one beam. One beam can include one or more antenna ports for transmitting data channels, control channels, sounding signals, etc. One or more antenna ports forming one beam can also be regarded as one antenna port set.

[0213] 2. Reference signal (RS): can also be referred to as pilot, reference sequence, reference signal, etc. For the sake of unity, reference signal is used hereinafter. Reference signal can be used for channel measurement or channel estimation, etc.

[0214] Channel measurement involved in the present application also includes beam measurement, i.e. obtaining beam quality information by measuring reference signal. As an example, parameters for measuring beam quality include at least one of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), signal-noise ratio (SNR), signal to interference plus noise ratio (SINR) (or can be simply referred to as signal to interference noise ratio). For the sake of convenience, channel measurement involved in the embodiments of the present application can be regarded as beam measurement in the absence of special description.

[0215] As an example, reference signal involved in the present application can be any of the following: CSI-RS, synchronization signal block (SSB), sounding reference signal (SRS), user equipment specific reference signal (US-RS), demodulation reference signal (DMRS), phase-tracking reference signal (PTRS), cell reference signal (CRS), etc. It should be understood that the above-mentioned reference signals are only examples and should not constitute any limitation on the present application. The present application does not exclude the possibility of defining other reference signals in future protocols to achieve the same or similar functions.

[0216] In addition, the reference signal can be understood as a reference signal associated with a handover candidate cell configuration. The handover candidate cell can also be referred to as a candidate cell or a neighbor cell, which can be a current serving cell or a non-serving cell, and has a physical cell identifier (PCI) different from that of a current primary cell (PCell). In addition, the reference signal can also be a reference signal associated with an additional PCI (additional PCI), i.e., a reference signal of a neighbor cell.

[0217] The terminal device can be configured with one or more candidate cell configurations, each of which can include a configuration of a reference signal resource.

[0218] 3. Reference signal resource: used to configure the transmission attributes of a reference signal.

[0219] Generally, a reference signal is configured in the form of a resource. The network device can configure each reference signal in the form of a resource to the terminal device, and one resource is one configuration information unit, which usually includes a parameter related to a reference signal, such as the time-frequency resource position of the reference signal, the number of ports, the time domain type (periodic / semi-static / non-periodic), etc. The terminal device can send a reference signal based on a reference signal resource, and the receiving terminal device can receive a reference signal based on a reference signal resource.

[0220] In order to distinguish different reference signal resources, each reference signal resource can correspond to a reference signal resource identifier, such as a CSI-RS resource indicator (CRI), an SSB resource indicator (SSBRI), and an SRS resource indicator (SRI).

[0221] 4. TCI-state: The network device can generate different beams pointing to different transmission directions. In downlink data transmission, when the network device uses a specific beam to send data to the terminal device, it needs to inform the terminal device of the information of the sending beam it uses, so that the terminal device can use the receiving beam corresponding to the sending beam to receive the data sent by the network device. One possible way is that the network device indicates the relevant information of the sending beam it uses to the terminal device through the transmission configuration indicator (TCI) field in the downlink control information (DCI).

[0222] For example, the TCI field size is 3 bits, which can represent 8 different field values (codepoints). Each value of the TCI field corresponds to an index of a TCI-state (tci-StateId), which can uniquely identify a TCI-state. A TCI-state includes several parameters by which the relevant information of the transmission beam can be determined. As an example, each TCI-state includes its own index tci-StateId, and two QCL information (QCL-Info). Each QCL-Info includes a cell field and a bandwidth part (BWP) identifier (ID), which respectively represent which BWP of which cell (i.e., different cells or different BWPs of the same cell) the TCI-state applies to. The QCL-Info can also include a reference signal (RS) indicating which reference signal resource forms a QCL relationship. In data transmission and channel measurement, a beam can correspond to a reference signal resource, such as one beam corresponding to one reference signal resource. Therefore, which reference signal resource forms a QCL relationship can also mean which beam forms a QCL relationship.

[0223] The QCL relationship means that two reference signal resources (or two antenna ports, antenna ports and reference signal resources are also one-to-one corresponding) have certain same spatial parameters. Which spatial parameters are the same can depend on the type of the QCL-Info, i.e., another field of the QCL-Info, qcl-Type. The qcl-Type can have four values {type A, type B, type C, type D}. Taking type D as an example, type D means that the two reference signal resources have the same spatial reception parameter information, i.e., the two beams have the same receiving beam. One of the two QCL-Info included in the TCI-state can be type D.

[0224] The following is a specific example to illustrate how the network device indicates the receiving beam information of the data transmission beam to a terminal device through the TCI-state, including the configuration, activation and indication of the TCI-state.

[0225] TCI-state configuration: The network device configures multiple TCI-states to the terminal device through RRC signaling. Each of these TCI-states includes a QCL-Info of type typeD. The network device can also configure TCI-states that do not include QCL-info of type typeD, which is not limited.

[0226] TCI-state activation: After the network device configures multiple TCI-states, it also needs to activate 8 of them through a medium access control (MAC) control element (CE) (MAC CE). These 8 TCI-states are one-to-one corresponding to the 8 values of the TCI field in the DCI. That is, which 8 TCI-states correspond to the 8 values of the TCI field in the DCI is determined through MAC CE signaling. The specific format of the MAC CE signaling can refer to the protocol, which is not limited.

[0227] TCI-state indication: The network device indicates a specific TCI-state through the TCI field in the DCI. For example, the value of the TCI field in the DCI sent by the network device to the terminal device is 000, indicating that the data transmission beam adopts the TCI-state corresponding to 000. The reference signal contained in the QCL-Info of type typeD in this TCI-state is the reference signal (such as CSI-RS) with index #1, indicating that the receiving beam corresponding to the data transmission beam is the same as the receiving beam corresponding to the CSI-RS with index #1. The receiving beam corresponding to the CSI-RS with index #1 can be determined through a beam measurement process and is known to the terminal device. Therefore, through the specific value of the TCI field, the terminal device can determine the receiving beam corresponding to the data transmission beam, and thus adopt the corresponding receiving beam to receive data.

[0228] 5、Unified TCI: A unified beam indication framework, the network device can indicate a beam for the terminal device, which is used for multiple channels and / or reference signals at the same time. The common beam can be an uplink common beam, a downlink common beam, or an uplink-downlink common beam, which can be used by the terminal device in subsequent transmission. That is, the network device can indicate an uplink common beam for the terminal device, which is used for the transmission of multiple uplink channels and / or uplink reference signals. It can also indicate a downlink common beam for the terminal device, which is used for the transmission of multiple downlink channels and / or downlink reference signals. It can also indicate an uplink-downlink common beam for the terminal device, which is used for the transmission of multiple uplink channels and / or uplink reference signals, and multiple downlink channels and / or downlink reference signals. That is, the uplink-downlink common beam can be used for both uplink transmission and downlink transmission.

[0229] As an example, the terminal device can be configured with two types of TCI-state, respectively referred to as downlink (DL) or joint TCI (DL or joint TCI) and uplink (UL) TCI (UL TCI).

[0230] For example, the terminal device is simultaneously configured with joint / DL TCI-state (such as a maximum of 128) and uplink TCI-state (UL TCI-state) (such as a maximum of 64).

[0231] For another example, in the configuration of the serving cell configuration (serving cell config) of the RRC signaling, the network device can configure the TCI mode currently used by the UE to be a joint mode or a separate mode. In the joint mode, indicating a joint TCI-state can be used for uplink and downlink transmission at the same time; in the separate mode, the network device indicates that the DL TCI-state and the UL TCI-state are used for uplink and downlink transmission, respectively.

[0232] When the terminal device receives the TCI-state activation signaling indicated by the MAC CE, the activation signaling includes the ID of the TCI-state, the terminal device determines which TCI is activated by the MAC CE according to the RRC configuration.

[0233] 6. Physical uplink control channel (PUCCH): can be used to transmit uplink control information (UCI) to support uplink and downlink data transmission. Of course, UCI can also be transmitted on the physical uplink shared channel (PUSCH).

[0234] As an example, the UCI carried by the PUCCH includes at least one of the following: a scheduling request (SR), hybrid automatic repeat request (HARQ)-acknowledgement (ACK) (HARQ-ACK) information, and channel state information (CSI) reference signal (CSI-RS).

[0235] Among them, the scheduling request can be used for uplink resource request.

[0236] Among them, the HARQ-ACK information (HARQ-ACK information): can also be referred to as HARQ information can represent feedback information for data (such as data on the physical downlink shared channel (PDSCH)), such as can be an acknowledgement (ACK) or a negative acknowledgement (NACK).

[0237] Among them, the CSI can include at least one of the following: channel quality indicator (CQI), precoding matrix indicator (PMI), rank indicator (RI), CSI-RS resource indicator (CRI), layer indicator (LI), RSRP or SINR, etc. The signal-to-interference-plus-noise ratio can also be referred to as the signal-to-interference-and-noise ratio.

[0238] As an example, PUCCH formats include the following: PUCCH format 0, PUCCH format 1, PUCCH format 2, PUCCH format 3, PUCCH format 4. Among them, PUCCH format 0 and PUCCH format 1 can also be referred to as short PUCCH, occupying 1-2 time domain units (such as symbols); PUCCH format 2, PUCCH format 3, PUCCH format 4 can also be referred to as long PUCCH, occupying 4-14 time domain units (such as symbols).

[0239] 7. Beam management: for example, including beam measurement, such as measuring based on reference signals, determining a better beam.

[0240] 5G can use high-frequency communication, that is, use ultra-high frequency band to transmit data. One of the main problems of high-frequency communication is that the signal energy decreases sharply with the transmission distance, resulting in short signal transmission distance. In order to overcome this problem, high-frequency communication uses analog beam technology, which concentrates signal energy in a small angle range by weighting processing of antenna array, forming a signal similar to a light beam (called analog beam, short for beam), thereby improving the transmission distance. Both network devices and terminal devices use beams for transmission. Specifically, the network device and the terminal device use a specific beam when performing uplink and downlink data transmission. At present, beam management is first based on SSB for beam coarse alignment, and then based on CSI-RS for beam fine adjustment. The possible process of beam management will be introduced below in combination with FIG. 3.

[0241] FIG. 3 is a schematic diagram of beam management suitable for embodiments of the present application.

[0242] As an example, the overall process of beam management can be divided into the following three stages.

[0243] Stage 1: Network device and terminal device beam coarse alignment, as shown in FIG. 3(a).

[0244] Specifically, the network device performs network device beam scanning based on SSB, that is, the network device sends beams in different directions at different times to complete the broadcast beam coverage of the cell. At the same time, the terminal device scans the receiving beam, that is, the terminal device also receives with different beams at different times. The terminal device determines the good network device beam and terminal device beam (such as the better network device beam and terminal device beam) according to the received signal strength.

[0245] Stage 2: Network device beam fine adjustment, as shown in FIG. 3(b).

[0246] Specifically, the network device determines the candidate beam according to the network device beam with good quality obtained in stage 1, performs scanning through the CSI-RS, and the terminal device performs receiving by using the receiving beam selected in stage 1, so as to fine-tune the network device beam, thereby determining the network device beam (such as a better network device beam).

[0247] Stage 3: terminal device beam fine-tuning, as shown in FIG. 3(c).

[0248] Specifically, the network device transmits the CSI-RS by using the beam obtained in stage 2, and the terminal device performs scanning on the beam, thereby determining the terminal device beam (such as a better terminal device beam), and completing the beam alignment. The flow is similar to stage 2.

[0249] Among them, stage 1, stage 2 and stage 3 are only examples for illustration, and the embodiments of the present application are not limited thereto. In the implementation, one system also does not necessarily implement all the above processes, for example, only stage 1 and stage 2 processes can be implemented, and the determination of the receiving beam on the terminal device side is left to the terminal device to implement.

[0250] 8, reporting of measurement results: at present, according to the time domain configuration behavior of reporting, the network device can configure three kinds of measurement result reporting (also called beam reporting, or beam measurement result reporting, or CSI reporting) processes: periodic reporting, semi-persistent reporting, and aperiodic reporting. The following is a brief introduction.

[0251] 1) Periodic reporting: first, the network device configures periodic reference signal measurement, that is, the network device periodically transmits measurement reference signals to the terminal device, and the terminal device measures the reference signals and periodically reports the measurement results. After the configuration signaling takes effect, the terminal device periodically reports the measurement report, and wants to terminate the measurement reporting process, can send RRC signaling to release the related configuration parameters of the measurement reporting process.

[0252] 2) Semi-persistent reporting: One is that the reference signal measurement is periodic, and the reporting of the measurement result is semi-persistent. First, the network device can configure periodic reference signals, i.e., the network device periodically sends measurement reference signals to the terminal device, and the terminal device measures these reference signals. When the terminal device receives the activation signaling (such as MAC CE signaling or DCI signaling) of the network device, the terminal device will continuously and periodically report the measurement result. Of course, the network device can also send the terminal device a deactivation signaling to deactivate the semi-persistent reporting process. The other is that both the reference signal measurement and the reporting of the measurement result are semi-persistent. When the terminal device receives the activation signaling (such as MAC CE signaling or DCI signaling) of the network device, the terminal device will continuously and periodically measure the reference signal and report the measurement result. When the terminal device receives the deactivation signaling sent by the network device, the terminal device stops the continuous reporting.

[0253] 3) Aperiodic reporting: The reporting is performed only after the terminal device receives a trigger signaling sent by the network device. And after the reporting is completed, the terminal device will stop continuing to report, i.e., the reporting is one-time.

[0254] 9, component carrier (CC);

[0255] FIG. 4 is a schematic diagram of a structure of a component carrier CC. In the current communication system, the transmittable frequency domain resource is defined on the CC. As shown in FIG. 4, the middle part of the CC is the available frequency domain resource, for example, including 21 resource blocks (RBs). Among them, the shaded part is the activated RB, and then the transceiver device can perform information interaction on the resource corresponding to the shaded part. The two sides of the CC are guard bands (GBs), which are used to separate the carriers of other frequency bands to prevent mutual interference between adjacent channels. Optionally, the bandwidths of the two GBs can be the same or different. In addition, the RBs where the GBs at the edges of the CC are located cannot be used.

[0256] 10. Reference signal associated with TCI state: The reference signal associated with TCI state can be a QCL Type D reference signal of the TCI state, or a reference signal associated with the QCL Type D reference signal of the TCI state. The QCL Type D reference signal of the TCI state is a reference signal whose qcl-Type in QCL-info in the TCI state is type D. The reference signal associated with the QCL Type D reference signal of the TCI state is an SSB that has a QCL relationship with the QCL Type D reference signal. The SSB is an SSB corresponding to a source QCL resource of a QCL chain. That is, the source QCL resource is an SSB resource. The QCL chain is determined according to the QCL Type D reference signal of the TCI state. For example, the network device indicates a QCL resource of the TCI state to be a CSI-RS resource. The QCL resource in the TCI state corresponding to the CSI-RS resource is a TRS resource. The TCI state corresponding to the CSI-RS resource can be understood as a TCI state adopted by the network device for transmitting the CSI-RS resource, or a TCI state adopted by the network device for transmitting a CSI-RS corresponding to the CSI-RS. The QCL resource in the TCI state corresponding to the TRS resource is an SSB resource. The TCI state corresponding to the TRS resource can be understood as a TCI state adopted by the network device for transmitting the TRS resource, or a TCI state adopted by the network device for transmitting a TRS corresponding to the TRS. As can be seen, the QCL resource (such as the CSI-RS resource) in the TCI state indicated by the network device to the terminal device, the QCL resource (such as the TRS resource) in the TCI state corresponding to the CSI-RS resource, and the QCL resource (such as the SSB resource) in the TCI state corresponding to the TRS resource constitute a QCL chain. The source QCL resource of the QCL chain is an SSB resource, and therefore the reference signal associated with the QCL Type D reference signal of the TCI state is an SSB corresponding to the SSB resource.

[0257] It should be noted that the three description methods of TCI state, TCI-state and TCI state can be replaced with each other.

[0258] In this application, "<" means less than, and "<=" means less than or equal to. The examples provided in this application are only examples and do not limit the application. "<" and "<=" in the examples can be replaced with each other, and the application does not limit the details. ">" means greater than, and ">=" means greater than or equal to. The ">" and ">=" in the examples can be replaced with each other, and the application does not limit the details. The examples provided in this application are only examples and do not limit the application. In this application, high can specifically mean greater than or greater than or equal to, and low can specifically mean less than or less than or equal to.

[0259] In this application, the terms of cell, serving cell, component carrier (CC) and the like can be replaced with each other. The serving cell can be a primary cell (PCell), a secondary cell (SCell) or a primary secondary cell (PScell). The cell of a primary component carrier (PCC) can be referred to as a PCell, and the cell of a secondary component carrier (SCC) can be referred to as an SCell. In addition, the cell can also be a neighboring cell of the serving cell (a cell corresponding to an additional PCI, a candidate cell and the like.

[0260] The above description of the terms is only for the convenience of understanding and does not limit the protection scope of the embodiments of the present application.

[0261] In the above reporting of the measurement results, either periodic, semi-persistent or aperiodic reporting triggered by the network device, that is, the timing of the reporting is determined by the network device. This way results in a large overhead of uplink resources. Specifically, in periodic and semi-persistent measurement reporting, the terminal device needs to report the measurement results every period, and these measurement results can be meaningless to the network device. For example, the current measurement result is not different from the last reported measurement result (such as the optimal beam does not change), and reporting such measurement results is meaningless, resulting in waste of uplink resources.

[0262] In addition, since the terminal device judges whether the event triggering condition is met, and then triggers the reporting of the measurement report related to the event, the network device cannot know which cells have events, and which events occur in the cells.

[0263] Therefore, the present application provides a measurement result reporting method and device to report at least one event related measurement result of one or more cells, reduce the overhead of uplink resources, and realize reasonable allocation of resources.

[0264] The measurement result reporting method provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings. The embodiments of the present application can be applied to the communication system shown in FIG. 1. It should be understood that the embodiments of the present application can be applied to the scenario of communication between the sending end and the receiving end, for example, the embodiments of the present application can be applied to the uplink, downlink or sidelink communication scenario.

[0265] It should also be understood that the embodiments shown below do not particularly limit the specific structure of the subject performing the method provided by the embodiments of the present application, as long as the subject is capable of performing communication according to the method provided by the embodiments of the present application through running codes or programs recorded with the method provided by the embodiments of the present application. For example, the method provided by the embodiments of the present application can be performed by a first device and a second device. In the case of no special description, the "first device" in the present application can refer to the first device itself (for example, a terminal device), a component in the first device (for example, a communication module, a processor, a circuit, a chip (such as a modem chip, also known as a baseband chip, or a SoC chip or a SIP chip containing a modem core), or a chip system, etc.), or a logic module or software capable of realizing all or part of the functions of the first device. The "second device" in the present application can refer to the second device itself (for example, a network device), a component in the second device (for example, a communication module, a processor, a circuit, a chip, or a logic module or software capable of realizing all or part of the functions of the second device.

[0266] FIG. 5 is a flow diagram of a method for reporting measurement results according to an embodiment of the present application. As shown in FIG. 5, the method 500 includes the following steps.

[0267] S510, a first device (for example, a terminal device) acquires configuration information.

[0268] The configuration information is used to indicate information of X events corresponding to M cells, and M and X are integers greater than or equal to 1.

[0269] It can be understood that the X events corresponding to the M cells refer to that the X events are associated with the M cells, the M cells correspond to the X events, or the M cells support the X events, or the M cells are configured with the X events, or the sum of the number of events supported (or configured) by each of the M cells is X. Alternatively, each cell can be associated with one or more events, and the one or more events associated with each cell can be the same or different, for example, partially the same or completely different, which is not limited in the present application.

[0270] Alternatively, the configuration information can include information of the M cells and information of the X events. Correspondingly, the first device learns the M cells and the X events based on the configuration information.

[0271] Optionally, the configuration information further comprises the association between the M cells and the X events, or in other words, the configuration information comprises the information of the X events corresponding to the M cells, or the configuration information comprises the association between each of the M cells and one or more of the X events. Correspondingly, the first device learns the X events corresponding to the M cells based on the configuration information.

[0272] For example, the configuration information comprises the index or identifier of each of the M cells and the index or identifier of each of the X events. Optionally, the event index included in the configuration information indicates that the corresponding event has been activated, or the configuration information comprises the information of whether the event has been activated.

[0273] For another example, the configuration information comprises one or more cell tables (or the index of one or more cell tables) and one or more event tables (or the index of one or more event tables), wherein one cell table comprises one or more cells and one event table comprises one or more events. In this way, based on the index of the cell table and the index of the event table included in the configuration information, the first device can learn the cells included in the cell table and the events included in the event table.

[0274] For another example, the configuration information comprises the value of M and the value of X, for example, M=2 and X=4.

[0275] For example, assuming that there are M=2 cells, for example, cell A and cell B, wherein cell A is associated with event 1 and event 2, and cell B is associated with event 3 and event 4, then X=4; or cell A is associated with event 1, and cell B is associated with event 2, event 3 and event 4, then X=4; or cell A can be associated with event 1 and event 3, and cell B is associated with event 2, event 3 and event 4, then X=5; or cell A can be associated with event 1 and event 4, and cell B is associated with event 1, event 2, event 3 and event 4, then X=6; or cell A and cell B are both associated with event 1, event 2, event 3 and event 4, then X=8.

[0276] Optionally, the number of configuration information is not limited in the present application, and can be one or more. If it is one configuration information, the configuration information is used to indicate the information of the X events corresponding to the M cells; if there are multiple configuration information, for example, x, x=M, then each of the x configuration information is used to indicate the information of the events corresponding to one of the M cells, or xM, which means that there is one configuration information used to indicate the information of the events corresponding to multiple cells of the M cells. In summary, the x configuration information is used to collectively configure the information of the events corresponding to one of the M cells, and the specific configuration manner is not limited.

[0277] Further optionally, the method 500 further comprises: the second device sending activation signaling to the first device, for activating part or all of the configured or protocol specified events (i.e. X events corresponding to M cells).

[0278] Further optionally, the method 500 further comprises: the second device sending deactivation signaling to the first device, for deactivating part or all of the configured or protocol specified events (i.e. X events corresponding to M cells).

[0279] The aforementioned activation signaling or deactivation signaling can be carried in RRC, MAC CE or DCI. Optionally, the activation signaling or deactivation signaling can be carried in the same signaling as the configuration information.

[0280] For example, assuming that the second device configures the first device with M=2 cells (e.g. cell #1 and cell #2), and the protocol specifies or the second device configures the first device with event #1, event #2, event #3 and event #4. The configuration information includes the identification of the events corresponding to cell #1, which can be event index or information of whether the event is activated. Similarly, the configuration information also includes the identification of the events corresponding to cell #2, which can be event index or information of whether the event is activated. The information of whether the event is activated is indicated by bitmap, each bit corresponds to whether an event is activated. For example, the bitmap size is 4 bits, the bit value of 1 indicates that the corresponding event is activated, the bit value of 0 indicates that the corresponding event is not activated, and vice versa. When the information of whether the event of cell #1 is activated corresponds to bitmap=1010, it means that event #1 and event #3 are activated, and event #2 and event #4 are not activated. When event #1 and / or event #3 of cell #1 occurs, the measurement result related to the event #1 and / or event #3 can be reported.

[0281] The first device acquires the configuration information, including but not limited to the following two implementation manners.

[0282] In one implementation manner, the configuration information is from the network side.

[0283] For example, the configuration information can be indicated or configured by the network device through signaling, and optionally, the signaling can be RRC signaling, MAC CE signaling or DCI signaling. The specific implementation manner is shown in step S501.

[0284] S501, the second device (e.g. network device) sends (or indicates) configuration information to the first device;

[0285] Correspondingly, the first device receives the configuration information from the second device.

[0286] In another implementation, the configuration information can be predefined or preconfigured by the protocol. The predefinition can include a predefinition such as a protocol definition, and the preconfiguration can be implemented by pre-storing corresponding codes, tables, functions, texts, strings, or other manners that can be used to indicate relevant information (e.g., configuration information) in the network device and / or the terminal device, and the specific implementation manner is not limited in the present application.

[0287] Regarding the determination of the X events corresponding to the M cells, the following multiple cases are included but not limited to.

[0288] In case one, the X events corresponding to the M cells are determined based on the indication information in the following step S502. In other words, the X events are events supported by the terminal device, or in other words, the X events are events indicated by the terminal device through the indication information. In this case, the network device can not need to configure the information of the X events to the terminal device.

[0289] In case two, the X events corresponding to the M cells are configured by the network device, that is, the network device itself configures (or selects) the X events. In this case, it can be defaulted that the terminal device supports all events or supports the X events. In this case, the terminal device can not need to indicate the event information supported by itself to the network device.

[0290] In case three, the X events corresponding to the M cells are determined based on the indication information in the following step S502 and the events configured by the network device. For example, the network device configures at least one event, the terminal device supports at least one event, and the X events are determined based on the at least one event configured by the network device and the at least one event supported by the terminal device.

[0291] In case four, the X events corresponding to the M cells are predefined or preconfigured by the protocol.

[0292] Optionally, the X events can include at least one of: the first beam quality is lower than or equal to a first threshold; the second beam quality is higher than or equal to a second threshold; the second beam quality is higher than or equal to a third threshold of the first beam quality; an absolute difference between the second beam quality and the first beam quality is lower than or equal to a fourth threshold; the first beam quality is lower than or equal to a fifth threshold and the second beam is higher than or equal to a sixth threshold; the first beam quality is lower than or equal to a preset beam quality seventh threshold; the first beam does not belong to K best beams; the second beam quality is higher than or equal to an eighth threshold of a reference signal with the worst signal quality among reference signals associated with activated TCI state(s); the second beam quality is higher than or equal to a ninth threshold of a reference signal with the worst signal quality among reference signals associated with activated TCI state(s); there are S second beams with beam qualities higher than or equal to a tenth threshold of the first beam quality, S being an integer greater than or equal to 2; or, there is at least one second beam quality higher than or equal to an eleventh threshold of a beam quality of a configured reference signal.

[0293] The first beam represents a serving beam, i.e., a current serving beam. For example, the first beam can be at least one of the following: a reference signal in the currently indicated TCI-state with QCL type being QCL type D; a reference signal associated with the reference signal in the currently indicated TCI-state with QCL type being QCL type D (i.e., an SSB having a QCL relationship with the QCL type D reference signal); a reference signal in the UL TCI-state applied to the current uplink transmission (PUSCH / PUCCH / SRS / CSI-RS / physical random access channel (PRACH)) with QCL type being type D; a reference signal in the downlink or joint TCI-state (DL or joint TCI-state) applied to the current downlink transmission (physical downlink control channel (PDCCH) / physical downlink shared channel (PDSCH) / SRS / CSI-RS) with QCL type being type D; a reference signal in the UL TCI-state applied to the current uplink transmission (PUSCH / PUCCH / SRS / CSI-RS / PRACH) with QCL type being type D corresponding to an SSB satisfying the QCL type D relationship; a reference signal in the DL or joint TCI-state applied to the current downlink transmission (PDCCH / PDSCH / SRS / CSI-RS) with QCL type being type D corresponding to an SSB satisfying the QCL type D relationship; one or more reference signals configured or indicated by the network device for monitoring the first beam; a reference signal with the worst signal quality among the reference signals associated with the activated TCI state(s); or a reference signal with the best signal quality among the reference signals associated with the activated TCI state(s). The indicated TCI-state can be one or more of an indicated joint TCI state, a DL TCI state, or a UL TCI state.

[0294] The second beam represents a beam different from the serving beam, which can also be referred to as a new beam, such as a beam of a current serving cell or the current cell different from the serving beam, or a beam of a candidate cell / neighbor cell, etc. For example, the second beam can be at least one of the following: a reference signal associated with the activated TCI state(s) (except the indicated TCI state); one or more reference signals configured or indicated by the network device for monitoring the second beam; or a reference signal associated with the configured TCI state(s) (except the indicated TCI state).

[0295] Optionally, the first beam can include one or more beams, and the second beam can also include one or more beams, and the number of the first beam and the second beam is not limited in the present application. Wherein, the number of the first beam / second beam can be determined according to the number of UL / DL / joint TCI-state indicated by the network device, for example, the UL / DL / joint TCI-state indicated by the DCI signaling; or the number of the first beam / second beam (or the maximum value of the number of the first beam / second beam) can be predefined or preconfigured.

[0296] Optionally, the reference signal can be SSB, CSI-RS, SRS, or a path loss reference signal, etc.

[0297] Optionally, the beam quality can be characterized, for example, by at least one of: a reference signal received power (RSRP), a signal to interference plus noise ratio (SINR), a Layer 1 reference signal received power (L1-RSRP), a Layer 1 signal to interference plus noise ratio (L1-SINR), a synchronization signal based signal to interference plus noise ratio (SS-SINR), a synchronization signal based reference signal received power (SS-RSRP), a CSI reference signal based signal to noise and interference ratio (CSI-RSRP), a CSI reference signal based signal to interference plus noise ratio (CSI-SINR), or a channel quality indicator (CQI).

[0298] Optionally, the thresholds in this application, such as the first threshold, the second threshold, …, or the eleventh threshold, can be predefined or preconfigured, or configured, or signaling indicated, or UE determined, which is not limited herein. The thresholds can be the same or different. The two thresholds can be associated, that is, the associated threshold can be derived through one threshold, or can not be associated. The size relationship between the two thresholds is not limited. The unit of the threshold can be decibel (dB) or decibel milliwatt (dBm), etc.

[0299] The following will be described by taking the above-mentioned X events as examples.

[0300] Example 1: the first beam quality is lower than or equal to the first threshold.

[0301] For distinction, this event is referred to as event #A, in other words, event #A indicates that the current serving beam quality is less than or equal to a certain threshold, such as the first threshold (such as threshold 1).

[0302] Example 2: the second beam quality is higher than or equal to the second threshold.

[0303] For distinction, this event is referred to as event #B, in other words, event #B indicates that the beam quality of at least one new beam (that is, the second beam) is greater than or equal to a threshold, such as the second threshold (such as threshold 2).

[0304] As an example, the new beam is one of the reference signals associated with the activated TCI-states (except the indicated TCI-state), or the reference signal configured by the network device (such as the reference signal configured by the network device for measurement, or the reference signal configured by the network device for the terminal device to monitor the occurrence of the event or event #B).

[0305] Example 3: the second beam quality is higher than or equal to the first beam quality third threshold.

[0306] For distinction, this event is referred to as event #C, in other words, event #C indicates that the beam quality of at least one new beam is greater than the beam quality of the current serving beam, and the difference between the beam quality of the new beam and the beam quality of the current serving beam is greater than or equal to a threshold, such as the third threshold (such as threshold 3).

[0307] Alternatively, the event #C can also be described as: the first beam quality is lower than or equal to the second beam quality by a threshold, at this time the threshold can be a value less than 0 dB. Optionally, “the first beam quality is lower than or equal to the second beam quality by a threshold” can also be an event different from event #C, which is not limited herein.

[0308] Example 4, the (absolute) difference between the second beam quality and the first beam quality is lower than or equal to a fourth threshold.

[0309] For the sake of distinction, this event is referred to as event #D. In other words, event #D indicates that the difference between the beam quality of the at least one new beam and the beam quality of the current serving beam is lower than or equal to a threshold, or event #D indicates that the absolute value of the difference between the beam quality of the at least one new beam and the beam quality of the current serving beam is lower than or equal to a threshold, such as a fourth threshold (e.g., threshold 4).

[0310] The above are only example descriptions given for the sake of understanding, and embodiments of the present application are not limited thereto. Other events can also be included in the X events. Several examples are listed below.

[0311] Example 5, the first beam quality is lower than or equal to a fifth threshold, and the second beam quality is higher than or equal to a sixth threshold, and optionally, the sixth threshold is greater than or equal to the fifth threshold.

[0312] For the sake of distinction, this event is referred to as event #E. In other words, event #E indicates that the beam quality of the at least one new beam is greater than a certain threshold, and the beam quality of the current serving beam is lower than or equal to a threshold.

[0313] Example 6, the first beam quality is lower than or equal to a preset beam quality seventh threshold. For example, the first beam quality is lower than or equal to a first beam QCL type D SSB quality seventh threshold. Optionally, the seventh threshold is less than 0 dB, or in other words, the first beam QCL type D SSB quality is higher than or equal to the first beam quality seventh threshold, and optionally, the seventh threshold is greater than 0 dB. For example, the current serving beam is a CSI-RS with QCL type type D in the currently indicated TCI state, and the reference signal of the QCL type type D of the CSI-RS is an SSB, and the quality of the CSI-RS is lower than the quality of the SSB by a threshold 7, and at this time the threshold 7 is less than 0 dB.

[0314] For the sake of distinction, this event is referred to as event #F. For example, the current serving beam is a CSI-RS with QCL type type D in the currently indicated TCI state, and the preset beam is a reference signal (e.g., SSB) that satisfies the QCL type type D of the CSI-RS, and the quality of the CSI-RS is lower than or equal to the quality of the reference signal (e.g., SSB) by a threshold (i.e., a seventh threshold), and at this time the seventh threshold is a value less than 0 dB.

[0315] This event #F can also be described as: the preset beam quality is higher than or equal to the first beam quality seventh threshold, and at this time the seventh threshold is a value greater than 0 dB.

[0316] Example 7, the first beam does not belong to the K best beams, K can be an integer greater than or equal to 1, and optionally, the K best beams can exist in the form of a beam set / group / table.

[0317] For distinction, this event is referred to as event #G, in other words, event #G indicates that the beam quality of the current serving beam is not good, for example, lower than or equal to a certain preset threshold, so when the beam quality of the first beam is lower than or equal to the preset threshold, the terminal device can trigger the reporting of the information of event #G.

[0318] Example 8, the second beam quality is higher than or equal to a ninth threshold of the reference signal with the worst signal quality among the reference signals associated with the activated TCI state(s).

[0319] For distinction, this event is referred to as event #H, in other words, event #H indicates that there is at least one new beam whose beam quality is greater than or equal to the reference signal with the worst signal quality among the reference signals associated with the activated TCI state(s), and the difference between the beam quality of the new beam and the beam quality of the reference signal with the worst signal quality is greater than or equal to a threshold, such as the eighth threshold (e.g., threshold 8).

[0320] Example 9, the second beam quality is higher than or equal to a ninth threshold of the reference signal with the worst signal quality among the reference signals associated with the activated TCI state(s).

[0321] For distinction, this event is referred to as event #I, in other words, event #I indicates that there is at least one new beam whose beam quality is greater than or equal to the reference signal with the best signal quality among the reference signals associated with the activated TCI state(s), and the difference between the beam quality of the new beam and the beam quality of the reference signal with the best signal quality is greater than a threshold, such as the ninth threshold (e.g., threshold 9).

[0322] Example 10, the beam quality of the S second beams is higher than or equal to a tenth threshold of the first beam quality. Optionally, the value of S can be protocol predefined or preconfigured, or can also be indicated or configured by the network device through signaling.

[0323] For distinction, this event is referred to as event #J, in other words, event #J indicates that there are multiple new beams whose beam quality is greater than or equal to the beam quality of the current serving beam, and the difference between the beam quality of the new beam and the beam quality of the current serving beam is greater than a threshold, such as the tenth threshold (e.g., threshold 10).

[0324] Example 11, the beam quality of at least one second beam is higher than or equal to a eleventh threshold of the beam quality of the configured reference signal.

[0325] To distinguish, the event is referred to as event #K, in other words, event #K indicates that there is at least one new beam whose beam quality is greater than or equal to the beam quality of the configured reference signal, and the difference between the beam quality of the new beam and the beam quality of the configured reference signal is greater than a threshold, such as the eleventh threshold (such as threshold 11).

[0326] Taking event #A as an example, if event #A occurs, it indicates that the following situation occurs: the first beam quality is lower than the first threshold, or the first beam quality is equal to the first threshold. For example, if the terminal device determines through measurement that the first beam quality is lower than or equal to the first threshold, it is determined that event #A occurs. Taking event #B as an example, if event #B occurs, it indicates that the following situation occurs: the second beam quality is higher than the first threshold, or the second beam quality is equal to the second threshold. For example, if the terminal device determines through measurement that the second beam quality is higher than or equal to the second threshold, it is determined that event #B occurs. That is, the occurrence of the event triggers the reporting, that is, the reporting of the measurement result corresponding to the event is triggered.

[0327] It can be understood that in the above examples, the case of "equal to" can be a case of event occurrence, or it can also be a case of event non-occurrence, that is, the above-defined event can not contain "equal to", or it can also be other uses, which are not limited.

[0328] The X events can be any one or more of the foregoing events #A to #K, or can not be limited to the foregoing events, and the specific events are not limited in the present application.

[0329] Regarding the event triggering reporting of the X events corresponding to the M cells, one or more measurement report configurations can be associated, which will be illustrated below in the case one, case two and case three.

[0330] In the first case, an event occurring in X events corresponding to M cells is associated with a measurement report configuration. The measurement report configuration can be a CSI-reportConfig, an event-triggered reporting configuration, or an event-triggered measurement report configuration. Specifically, the CSI-reportConfig includes an indication information (for example, reportConfigType is configured as EventTriggered), which indicates that the report configuration is an event-triggered reporting configuration, or the CSI-reportConfig includes event-related information, such as event index, event corresponding threshold, and the like. Alternatively, the event-triggered reporting configuration is configured through a dedicated information element (IE), such as L1-EventTriggered-CSI-ReportConfig. In other words, one measurement report configuration can be associated with one or more cells or one or more CCs, and one measurement report configuration can be associated with one or more events corresponding to one or more cells or CCs. That is, one measurement report corresponds to one or more events of one or more cells or CCs.

[0331] Alternatively, the measurement report configuration can be the same as the configuration information in step S510. In this case, the configuration information in the application file and the measurement report configuration can be used interchangeably. Alternatively, the measurement report configuration can be different from the configuration information. For example, the measurement report configuration can include the configuration information, or the configuration information can include the measurement report configuration. Alternatively, the measurement report configuration and the configuration information can be two independent configuration information, which is not limited.

[0332] It can be understood that if one measurement report configuration is associated with M cells, the network device can send one measurement report configuration for the M cells, and the terminal device can report one measurement report. That is, the one measurement report includes the measurement result of at least one event associated with one of the M1 cells. In other words, the one measurement report includes the measurement result of at least one event occurring on one of the M1 cells.

[0333] Exemplarily, the measurement report configuration contains one or more of the following information, or is associated with one or more of the following information: information of one or more of the M cells; one or more event information corresponding to (or supported by) one or more of the M cells; reference signal measurement resource corresponding to one or more events corresponding to one or more of the M cells; event triggering reporting resource corresponding to one or more of the M cells; scheduling request or indication resource corresponding to one or more of the M cells; reporting quantity of the event corresponding to one or more of the M cells; or reporting number of the reporting quantity (or reporting quantity) of the event corresponding to one or more of the M cells.

[0334] The following is an example of the above-mentioned measurement report configuration.

[0335] Example 1: information of one or more of the M cells.

[0336] For example, an index or an identifier of a serving cell, which can be a primary cell (Pcell), a secondary cell (Scell), or a primary secondary cell (PScell), wherein the Pcell can also be referred to as a cell of a primary component carrier (PCC), the Scell can also be referred to as a cell of a secondary component carrier (SCC), and for another example, a cell corresponding to an additional physical cell identifier (additional PCI), i.e., a cell corresponding to a neighboring cell of the serving cell, which can also be referred to as a non-serving cell corresponding to the additional PCI, and can also be a cell corresponding to an additional PCI associated in an activated TCI state; a candidate cell index; a CC index; or a PCI.

[0337] Example 2: one or more event information corresponding to one or more of the M cells.

[0338] The one or more event information corresponding to one or more of the M cells can refer to one event information corresponding to one of the M cells, a plurality of event information corresponding to one of the M cells, one event information corresponding to a plurality of the M cells, or a plurality of event information corresponding to a plurality of the M cells.

[0339] For example, an event index corresponding to each cell, or one or more bits of one or more events supported by each cell, assuming that the event information includes R bits, an event index, which means rounding up, at this time it can be understood that one cell contains F events, and there are multiple cells containing the same events, that is, X is greater than or equal to F, F is an integer greater than 1; or, assuming that the event information includes X bits, the X bits correspond to X events one by one, and the xth bit in the X bits is used to indicate whether the xth event is supported by the corresponding cell, x = 1, 2, …, X. For example, if the value of the xth bit is “0”, the xth bit is used to indicate that the xth event is not supported by the corresponding cell, or if the value of the xth bit is “1”, the xth bit is used to indicate that the xth event is supported by the corresponding cell, and vice versa. If the measurement report configuration is associated with only one cell, the one or more event information corresponds to the cell. If the measurement report configuration is associated with multiple cells, one or more event information can be independently configured for each cell, or multiple cells can be associated with the same one or more event information.

[0340] Example 3: Reference signal measurement resource corresponding to one or more events corresponding to one or more cells in M cells.

[0341] The reference signal measurement resource can be configured separately for each event, or the same reference signal measurement resource can be configured for multiple events. The specific reference signal resource refers to the reference signal corresponding to the aforementioned current beam and new beam, which can be explicitly configured or implicitly determined. For example, if the measurement report configuration is associated with only one cell, the reference signal measurement resource corresponds to the cell; if the measurement report configuration is associated with multiple cells, the reference signal measurement resource corresponding to one or more events is independently configured for each cell.

[0342] Example 4: Event triggered reporting resource corresponding to one or more cells in M cells, used to carry beam measurement results triggered by events, such as periodic PUCCH resource, aperiodic PUSCH resource, semi-persistent PUCCH resource, semi-persistent PUSCH resource, etc. Only one reporting resource can be configured, that is, the same reporting resource corresponding to each cell, or the reporting resource can be configured for each cell.

[0343] Optionally, the event triggered reporting resource can be replaced by PUCCH resource, PUSCH resource, event triggered reporting resource, or UE triggered reporting resource, event triggered second channel resource, event triggered second uplink resource, etc.

[0344] Example 5, one or more of the M cells corresponding to the scheduling request or indication resource, used to carry the indication information of the event occurrence, the indication information used to indicate to the network device that the beam measurement result triggered by the event needs to be reported and / or there is an event occurrence, or used to request the reporting resource of the event trigger. Only one reporting indication resource can be configured, that is, the same scheduling request or indication resource corresponding to each cell, or the scheduling request or indication resource corresponding to each cell can be configured respectively.

[0345] Optionally, the scheduling request or indication resource can be replaced by any one of the following: reporting indication resource, PUCCH indication resource, PUSCH indication resource, scheduling request resource, pre-indication resource, pre-notification resource, event-triggered reporting scheduling request resource, event-triggered first channel resource, event-triggered first uplink resource, or UE-triggered reporting scheduling request resource.

[0346] Example 6, the reporting quantity (or reporting parameter) corresponding to one or more events of one or more of the M cells, and / or the number of reporting quantities of the events corresponding to one or more of the M cells. The reporting quantity corresponding to each event can be configured by the network or specified by the protocol. Similarly, if the reporting configuration is associated with one cell, the reporting quantity corresponding to each event and / or the number of reporting quantities correspond to one cell; if the reporting configuration is associated with multiple cells, each cell can correspond to the same reporting quantity corresponding to each event and / or the number of reporting quantities, or each cell can be configured with the reporting quantity corresponding to each event and / or the number of reporting quantities.

[0347] The reporting quantity (or reporting parameter) can include one or more of the following:

[0348] (1) Reporting parameter #1, current serving beam index or first beam index, which can also be understood as the reference signal index of the QCL type D in the currently indicated TCI state; or, the reference signal (such as SSB) index corresponding to the reference signal of QCL type D in the currently indicated TCI state that satisfies the QCL type D relationship; or, the reference signal (such as SSB) index of the QCL type D in the UL TCI state currently applied to the uplink transmission (PUSCH / PUCCH / SRS / PRACH); or, the reference signal (such as SSB) index of the QCL type D in the downlink or joint TCI state (DL or joint TCI state) currently applied to the downlink transmission (PDCCH / PDSCH / CSI-RS).

[0349] (2) Report parameter #2, the beam quality of the current serving beam, or in other words, the first beam quality. For example, the first beam quality can be represented using the RSRP, or SINR, or L1-RSRP, or L1-SINR, or SS-RSRP, or CSI-RSRP, or SS-SINR, or CSI-SINR corresponding to the current serving beam.

[0350] (3) Report parameter #3, the index of the second beam, which can also be understood as the index of the reference signal with QCL type D in the activated TCI-states (except the indicated TCI-state), or one or more reference signals (except the reference signal corresponding to the current serving beam) configured by the network device (for example, the reference signal configured by the network device for measurement, or the reference signal configured by the network device for the terminal device to monitor the occurrence of an event).

[0351] (4) Report parameter #4, the second beam quality. For example, the second beam quality can be represented using the RSRP, or SINR, or L1-RSRP, or L1-SINR, or SS-RSRP, or CSI-RSRP, or SS-SINR, or CSI-SINR corresponding to the second beam.

[0352] (5) Report parameter #5, one or more cell information, which can be understood as the cell to which the reported measurement report configuration corresponds, or the cell whose reference signal resource is measured (i.e., the cell corresponding to the reference signal resource associated with the reported measurement report configuration). For example, the cell information can be the handover candidate cell ID, the additional PCI, the component carrier (CC) index, or the PCI.

[0353] (6) Report parameter #6, the reason why the current serving beam quality is lower than the threshold (for example, the first threshold). For example, the network device beam is misaligned, the terminal device receiving beam is misaligned, the transmitting and receiving beams are misaligned, etc. The misalignment can also be replaced by the term such as expiration, invalidation, etc. Alternatively, it indicates whether the CSI-RS set measurement triggered with “on” repetition is used to poll the UE side receiving beam.

[0354] (7) reporting parameter #7, a reference signal resource set index, for example, a CSI-RS resource set (CSI-RS-ResourceSet) index, a CSI interference measurement (IM) resource set (CSI-IM-ResourceSet) index, a channel state information synchronization signal and PBCH block (CSI-SSB) resource set (CSI-SSB-ResourceSet) index, or a reference signal resource set index configured by the network device for the terminal device to monitor the occurrence of an event, used to indicate which reference signal resource set the current serving beam and / or the second beam belong to.

[0355] (8) reporting parameter #8, a reporting configuration index, for example, a CSI report configuration identifier (CSI-ReportConfigId), or an event-triggered reporting configuration index.

[0356] (9) reporting parameter #9, event information, for example, an index of an event that occurs, or one or more bits used to indicate whether an event occurs. For example, the event information includes R bits, used to indicate the index of the event that occurs, which means rounding up, at this time it can be understood that: one cell contains F events, there are multiple cells containing the same event, that is, X is greater than or equal to F, F is an integer greater than 1. For another example, the event information includes X bits, the X bits correspond to X events one by one, and the xth bit in the X bits is used to indicate whether the event corresponding to the xth bit occurs, x=1, 2, …, X. For example, the value of the xth bit is “0”, then the xth bit is used to indicate that the event corresponding to the xth bit occurs, or the value of the xth bit is “1”, then the xth bit is used to indicate that the event corresponding to the xth bit occurs. In this application, the information of the event that occurs or the event information that needs to report the related measurement result can be expressed in the above manner.

[0357] In this application, the information of the event that occurs in the X events corresponding to the M cells can be simply referred to as the information of the event that occurs or the event information, indicating information related to the event that occurs. As an example, the information of the event that occurs in the X events corresponding to the M cells includes at least one of the following: an index of the cell of the event that occurs, an index of the event that occurs, a number of cells of the event that occurs, a number of events that occur, and content of the event that occurs.

[0358] (10) Report parameter #10, capability index, used to determine the maximum number of SRS ports.

[0359] (11) Report parameter #11, channel state information, which can include one or more of precoding matrix indicator (PMI), rank indicator (RI), channel quality indicator (CQI), and layer indicator (LI).

[0360] The above report parameters are only examples given for the convenience of understanding, and embodiments of the present application are not limited thereto, and other report parameters can also be included.

[0361] In case two, each of the M (e.g., M is greater than 1) cells is associated with a measurement report configuration, or in other words, each of the cells associated with all the configured event-related information or the event-triggered report is associated with a measurement report configuration, which can be a CSI-reportConfig or an event-triggered report configuration, etc. In other words, in this mode, one measurement report configuration is associated with one cell or one CC, that is, one measurement report corresponds to one cell or one CC, or in other words, one measurement report configuration is associated with one cell or one CC event corresponding reference signal measurement resource. That is, the M cells or M CCs correspond to one or more measurement report configurations, which correspond to one or more measurement reports.

[0362] It can be understood that, assuming that one measurement report configuration is associated with one cell, the network device can send M measurement report configurations for the M cells, and the terminal device can report M1 measurement reports, that is, each measurement report includes the measurement result of at least one event associated with one of the M1 cells, that is, the measurement result of at least one event occurring on one of the M1 cells in each measurement report.

[0363] Exemplarily, the one measurement report configuration includes one or more of the following information, or in other words, the measurement report configuration is associated with one or more of the following information: one cell information; one or more event information corresponding to one cell; reference signal measurement resource corresponding to one or more events corresponding to one cell; event-triggered report resource corresponding to one cell; scheduling request or indication resource corresponding to one cell; report quantity of an event corresponding to one cell; or report quantity of each event corresponding to one or more events corresponding to one cell, wherein each event can correspond to one or more report quantities. For brevity, the specific parameter interpretation can refer to the related description of case one above, which will not be repeated here.

[0364] Case three, there are multiple cells associated with one measurement report configuration in M (e.g., M is greater than 1) cells, there is also one cell associated with one measurement report configuration, or one cell associated with multiple measurement report configurations. The measurement report configuration can be CSI-reportConfig, or event triggered reporting configuration, etc. In other words, in this way, one measurement report configuration can be associated with one cell or one CC, and one measurement report configuration can also be associated with multiple cells or multiple CCs, that is, one measurement report can correspond to one cell or one CC, and one measurement report can also correspond to multiple cells or multiple CCs. That is, M cells or M CCs correspond to T measurement report configurations, which correspond to T measurement reports, T is an integer greater than 1.

[0365] As an example, assuming M=3 and T=2, it is explained that there are three cells (such as cell 1, cell 2, and cell 3) corresponding to 2 measurement report configurations (such as measurement report configuration #1 and measurement report configuration #2), for example, cell 1 and cell 2 correspond to measurement report configuration #1, and cell 3 corresponds to measurement report configuration #2. When an event occurs on cell 1 and / or cell 2, the terminal device can report measurement report #1 corresponding to measurement report configuration #1 to indicate the measurement result of the event occurring on cell 1 and / or cell 2, and when an event occurs on cell 3, the terminal device can report measurement report #2 corresponding to measurement report configuration #2 to indicate the measurement result of the event occurring on cell 3.

[0366] As an example, assuming M=3 and T=4, it is explained that there are three cells (such as cell 1, cell 2, and cell 3) corresponding to 4 measurement report configurations (such as measurement report configuration #1, measurement report configuration #2, measurement report configuration #3, and measurement report configuration #4), for example, cell 1 corresponds to measurement report configuration #1, cell 2 corresponds to measurement report configuration #2 and measurement report configuration #3, measurement report configuration #2 and measurement report configuration #3 are respectively associated with different types (e.g., SSB and CSI-RS respectively) of reference signal measurement resources of cell 2, and cell 4 corresponds to measurement report configuration #4. When an event occurs on cell 1, the terminal device can report measurement report #1 corresponding to measurement report configuration #1 to indicate the measurement result of the event occurring on cell 1, when an event occurs on cell 2 and the monitored SSB corresponds to the event, the terminal device can report measurement report #2 corresponding to measurement report configuration #2 to indicate the measurement result of the event corresponding to the monitored SSB occurring on cell 2, and when an event occurs on cell 3, the terminal device can report measurement report #4 corresponding to measurement report configuration #4 to indicate the measurement result of the event occurring on cell 3.

[0367] Exemplarily, the measurement report configuration contains one or more of the following information, or is associated with one or more of the following information: information of one or more of the M cells; one or more event information corresponding to one or more of the M cells; one or more reference signal measurement resources corresponding to one or more events corresponding to one or more of the M cells; event triggering reporting resources corresponding to one or more of the M cells; scheduling request or indication resources corresponding to one or more of the M cells; reporting quantity of events corresponding to one or more of the M cells; or, reporting quantity of reporting parameters of events corresponding to one or more of the M cells. For brevity, the specific parameter interpretation is not repeated here, and can be referred to the related description of the above case one.

[0368] Optionally, the one or more measurement report configurations can be associated with event related reference signal measurement resources of one or more cells. The reference signal resource indicates a reference signal resource of the measurement corresponding to the event, or a reference signal resource of the measurement corresponding to the terminal device.

[0369] In an implementation manner, the network device configures reference signal resource information of measurements corresponding to different events.

[0370] Based on this manner, the terminal device determines the reference signal resource, including: the terminal device receives indication information, and the indication information indicates the reference signal resource. The information of the reference signal resource and the information of the X events can be carried in the same signaling, such as the configuration information in step S510 includes the information of the X events and the information of the reference signal resource; or can be carried in different signaling, which is not limited.

[0371] In an example, the network device configures different reference signal resources (one or more reference signals), or reference signal resource sets (containing one or more reference signals), or reference signal resource configurations (containing one or more reference signal resource sets) corresponding to different events, for monitoring whether a certain event occurs, and triggering reporting when the event occurs. Alternatively, the measurement result triggered by the reporting of a certain event corresponds to: the reference signal resource / reference signal resource set / reference signal resource configuration corresponding to the event.

[0372] Optionally, the network device configures or associates different reference signal resources / reference signal resource sets / reference signal resource configurations for different events; or the network device configures or associates the same reference signal resources / reference signal resource sets / reference signal resource configurations for different events.

[0373] In another example, the network device sends a measurement report configuration, also called an event triggering reporting configuration or an event triggering measurement report configuration, to the terminal device. The configuration is a special event triggering reporting configuration or an event triggering measurement report configuration.

[0374] For example, the measurement report configuration information contains information indicating that the report corresponds to event-triggered measurement results only, or contains information indicating that the report can be event-triggered, or the measurement report configuration is a special RRC information element, and the terminal device knows that the configuration is an event-triggered report configuration. Further, the measurement report configuration can also be associated with reference signal resources / reference signal resource sets / reference signal resource settings, so that the terminal device can determine which reference signal resources can be reported in the event report.

[0375] In another example, the network device sends different event-triggered measurement report configurations to the terminal.

[0376] For example, the measurement report configuration information contains event information, such as event index, for indicating that the measurement report configuration corresponds to a specific event, and if the event occurs, the report is made according to the corresponding configuration information.

[0377] In another implementation, the reference signal resource information of the measurement corresponding to different event-triggered reports is predefined.

[0378] In an example, the reference signal resource of the measurement corresponding to different event-triggered reports is predefined as the reference signal resource corresponding to the current serving beam. For example, the reference signal resource of the measurement corresponding to different event-triggered reports is the reference signal of QCL type typeD in the currently indicated TCI-state, or the reference signal of QCL type typeD in the UL TCI-state applied to the current uplink transmission (PUSCH / PUCCH / SRS / physical random access channel (PRACH)), or the reference signal of QCL type typeD in the DL or joint TCI-state applied to the current downlink transmission (PDCCH / PDSCH / CSI-RS).

[0379] In another example, the reference signal resource of the measurement corresponding to different event-triggered reports is predefined as the reference signal of QCL type typeD in the currently activated TCI-state.

[0380] The above predefined reference signal resource can correspond to different events or the same event, and this is not limited. In addition, the above reference signal can be a reference signal of a serving cell or a reference signal of a candidate cell / neighbor cell.

[0381] Optionally, before the terminal device obtains the configuration information, the terminal device can report capability information to the network device, that is, before step S510, the method can further include the following step S502.

[0382] S502, the first device sends indication information to the second device.

[0383] Correspondingly, the second device receives the indication information from the first device.

[0384] The indication information indicates information of an event corresponding to the first device, or information of an event supported by the first device, and the indication information can also be referred to as terminal capability information.

[0385] As an example, the specific implementation manner can include but is not limited to: if the terminal device reports the terminal capability information, it indicates that the terminal device supports the capability; otherwise, if the terminal device does not report the terminal capability information, it indicates that the terminal device does not support the capability; or, if the terminal device reports the terminal capability information, it indicates that the terminal device supports the capability; if the terminal device reports that the terminal capability information is not supported, it indicates that the terminal device does not support the capability. Or, the terminal device supports capability #1, which means that it supports capability #2, so when the terminal device reports that it supports capability #1, even if it does not report the information of capability #2, it also indicates that the terminal device supports capability #2.

[0386] In the present application, the event represents an event related to a terminal device initiated report (UE initiated report), or an event related to a terminal device initiated measurement report, or an event related to a terminal device initiated report (or measurement report) after active measurement, or a specific condition related to a terminal device initiated measurement report. For example, the terminal device can actively perform measurement (such as beam measurement, or channel measurement, etc.), and then obtain a measurement report related to the event. For another example, the terminal device can perform measurement based on a reference signal according to the configuration of the reference signal resource, and then obtain a measurement report related to the event. For another example, the terminal device actively measures, and reports a measurement report related to the event when a specific condition is met. The event can also be replaced by any of the following: trigger event, layer 1 (L1) trigger event, CSI measurement report trigger event, beam measurement report trigger event, L1 CSI report trigger event, L1 beam measurement report trigger event, etc. The naming is not limited by the embodiments of the present application.

[0387] In the present application, the report related to the event can be replaced by any of the following: event triggered or terminal device initiated report, event triggered or terminal device initiated beam report, event triggered or terminal device initiated CSI report, event triggered or terminal device initiated measurement report, event triggered or terminal device initiated beam measurement result report, event triggered or terminal device initiated interference measurement report, interference measurement report, CSI report, or beam measurement result report, etc.

[0388] Optionally, the indication information indicates at least one of the following: whether the terminal device supports the capability of event triggered reporting, one or more events corresponding to the event triggered reporting supported by the terminal device, whether each CC (or cell) of the terminal device supports the capability of event triggered reporting, one or more events corresponding to the event triggered reporting supported by each CC of the terminal device, a maximum number of event triggered beam reporting configurations supported by the terminal device, a maximum number of event triggered reporting configurations supported by each CC of the terminal device, a number of cells associated with an event triggered beam reporting configuration, a number of events of each cell associated with an event triggered beam reporting configuration, a maximum number of reported beams supported by each event supported by the terminal device, or a maximum number of newly reported beams (i.e., second beams) supported by each event supported by the terminal device.

[0389] In the present application, the event triggered reporting can be mutually replaced by any one of the following: event triggered beam reporting, event triggered channel state information (CSI) reporting, event triggered beam measurement result reporting, or event triggered interference measurement reporting, etc., without limitation. Optionally, the event triggered reporting can also be referred to as UE initiated report.

[0390] In this application, the measurement report configuration can be replaced by any of the following: event triggered or terminal device initiated report configuration, event triggered or terminal device initiated beam report configuration, event triggered or terminal device initiated CSI reportConfig, event triggered or terminal device initiated measurement report configuration, event triggered or terminal device initiated beam measurement result report configuration, event triggered or terminal device initiated interference measurement report configuration, interference measurement report configuration, CSIreportConfig, UE initiated reportConfig, Event rigger-CSI-ReportConfig, or beam measurement result report configuration, etc. Specifically, the measurement report configuration can be a CSI-reportConfig, which configures an indication information (e.g. reportConfigType is configured as EventTriggered) indicating that the report configuration is an event triggered reporting configuration, or the CSI-reportConfig contains event related information such as event index, event corresponding threshold, etc. Then it is indicated that the report configuration is an event triggered reporting configuration. Alternatively, the measurement report configuration can be configured by a special information element (IE), such as L1-EventTriggered-CSI-ReportConfig.

[0391] Next, the specific information indicated by the indication information is illustrated by examples.

[0392] Example 1: The indication information indicates whether the terminal device supports the capability of event triggered reporting.

[0393] For example, whether the terminal device supports the capability of event triggered reporting can be implemented by at least one bit. It is assumed that 1 bit is used to indicate whether the terminal device supports the capability of event triggered reporting. If the bit is set to "0", it means that the terminal device supports the capability of event triggered reporting. If the bit is set to "1", it means that the terminal device does not support the capability of event triggered reporting, and vice versa.

[0394] For another example, whether the terminal device supports the capability of event triggered reporting is indicated by whether the capability of event triggered reporting is reported. If the terminal device does not report the capability of event triggered reporting, it is assumed that the terminal device supports the capability of event triggered reporting. Alternatively, if the terminal device does not report the capability of event triggered reporting, it is assumed that the terminal device does not support the capability of event triggered reporting.

[0395] The above is an example for illustration, and embodiments of the present application are not limited thereto. For example, whether the terminal device supports the event triggered reporting capability can also be indicated by a specific field. If the indication information includes the specific field, it indicates that the terminal device supports the event triggered reporting capability; if the indication information does not include the specific field, it indicates that the terminal device does not support the event triggered reporting capability.

[0396] Example 2: The indication information indicates one or more events corresponding to the event triggered reporting supported by the terminal device. In short, the indication information indicates the events supported by the terminal device.

[0397] For example, the indication information includes the index of each event supported by the terminal device; or, in the form of a bitmap. Assuming that there are events 1 to 4, if the event triggered reporting corresponding to the events supported by the terminal device includes events 1 and 4, the terminal device can send indication information, which can include the indexes of events 1 and 4, or the indication information can include bitmap = 1001, indicating that the terminal device supports event triggered reporting of events 1 and 4, and does not support event triggered reporting of events 2 and 3.

[0398] For another example, the indication information includes the index of each event table supported by the terminal device, and one event table includes one or more events.

[0399] For another example, the indication information includes the number of events supported by the terminal device.

[0400] For another example, the terminal does not report one or more events corresponding to the event triggered reporting supported by the terminal, indicating that it does not support any event triggered reporting. Or, the terminal does not report one or more events corresponding to the event triggered reporting supported by the terminal, indicating that the terminal supports all protocol specified events.

[0401] Example 3: The indication information indicates whether each CC (or cell) of the terminal device supports the event triggered reporting capability.

[0402] For example, whether each CC of the terminal device supports the event triggered reporting capability can be implemented by at least one bit. It is assumed that whether each CC of the terminal device supports the event triggered reporting capability is indicated by 1 bit. If the bit is set to "0", it indicates that each CC of the terminal device supports the event triggered reporting capability; if the bit is set to "1", it indicates that each CC of the terminal device does not support the event triggered reporting capability. It is assumed that there are 4 CCs, and whether each CC supports the event triggered reporting capability is indicated by 2 bits: if CC#0 and CC#1 of the terminal device support the event triggered reporting capability, and CC#2 and CC#3 of the terminal device do not support the event triggered reporting capability, the terminal device can report "00" and "01", indicating that CC#0 and CC#1 of the terminal device support the event triggered reporting capability.

[0403] For another example, whether each CC of the terminal device supports the event triggered reporting capability can be implemented by a bit bitmap. It is assumed that there are 4 CCs, i.e., the size of the bit bitmap is 4 bits, if CC#0 and CC#1 of the terminal device support the event triggered reporting capability, and CC#2 and CC#3 of the terminal device do not support the event triggered reporting capability, bit "1" indicates that the CC of the terminal device supports the event triggered reporting capability, and bit "0" indicates that the CC of the terminal device does not support the event triggered reporting capability, the terminal device can send bitmap="1100".

[0404] For another example, whether each CC of the terminal device supports the event triggered reporting capability is indicated by whether the capability of supporting the event triggered reporting is reported. If the terminal device does not report the capability of not supporting the event triggered reporting, it can be defaulted that each CC of the terminal device supports the event triggered reporting capability. Or, for example, if the terminal device does not report the capability of supporting the event triggered reporting, it can be defaulted that each CC of the terminal device does not support the event triggered reporting capability.

[0405] The above is an example for illustration, and the embodiments of the present application are not limited thereto. For example, whether each CC of the terminal device supports the event triggered reporting capability can also be indicated by a specific field, if the indication information includes the specific field, it indicates that each CC of the terminal device supports the event triggered reporting capability; if the indication information does not include the specific field, it indicates that each CC of the terminal device does not support the event triggered reporting capability.

[0406] Example 4, the indication information indicates one or more events corresponding to the event triggered reporting supported by each CC of the terminal device, in short, the indication information indicates the events supported by each CC of the terminal device.

[0407] For example, the indication information includes indexes of each event supported by each CC of the terminal device; or, is in the form of a bitmap. Assuming that CC#1 supports events 1, 2 and 3, if the terminal device supports event-triggered reporting of events 1 and 3 for CC#1, the terminal device can send indication information, which can include indexes of events 1 and 3, or the indication information can include bitmap = 101, indicating that the terminal device supports event-triggered reporting of events 1 and 3, and does not support event-triggered reporting of event 2.

[0408] For another example, the indication information includes indexes of each event table supported by each CC of the terminal device, and one event table includes one or more events.

[0409] For yet another example, the indication information includes the number of events supported by each CC of the terminal device.

[0410] Example 5: The indication information indicates the maximum number of event-triggered beam reporting configurations supported by the terminal device.

[0411] For example, if the maximum number of event-triggered beam reporting configurations supported by the terminal device is 4, it means that the number of measurement reports of event-triggered beam reporting supported by the terminal device can be 1, 2, 3 or 4.

[0412] Example 6: The indication information indicates the maximum number of event-triggered reporting configurations supported by each CC of the terminal device.

[0413] For example, if the maximum number of event-triggered reporting configurations supported by each CC of the terminal device is 3, it means that the number of measurement reports of event-triggered reporting supported by the terminal device for each of the M cells can be 1, 2 or 3.

[0414] Example 7: The indication information indicates the number of associated cells supported by the event-triggered beam reporting configuration.

[0415] For example, if the number of associated cells supported by the event-triggered beam reporting configuration is 4, it means that the number of associated cells supported by the terminal device for event-triggered beam reporting can be 1, 2, 3 or 4.

[0416] Example 8: The indication information indicates the number of events supported by each associated cell for the event-triggered beam reporting configuration.

[0417] For example, if the number of events supported by each associated cell for the event-triggered beam reporting configuration is 2, it means that the number of events supported by the terminal device for each associated cell for event-triggered beam reporting can be 1 or 2.

[0418] Example 9: The indication information indicates the maximum number of reporting beams supported by each event supported by the terminal device.

[0419] For example, the terminal device supports event #1 and event #2, and the indication information includes that the maximum number of reported beams supported by the supported event #1 is 2, and the maximum number of reported beams supported by the supported event #2 is 3. When event #1 occurs, the number of reported beams associated with event 1 can be 1 or 2; when event #2 occurs, the number of reported beams associated with event 2 can be 1, 2 or 3.

[0420] For another example, the terminal device supports event #1 and event #2, and the indication information includes that the maximum number of reported beams supported by the supported event #1 and event #2 supported by the terminal device is 3. When event #1 occurs, the number of reported beams associated with event 1 can be 1, 2 or 3; when event #2 occurs, the number of reported beams associated with event 2 can be 1, 2 or 3.

[0421] Example 10, the indication information indicates the maximum number of reported new beams (i.e. second beams) supported by each event supported by the terminal device.

[0422] For example, the terminal device supports event #1 and event #2, and the indication information includes that the maximum number of reported new beams supported by the supported event #1 is 2, and the maximum number of reported new beams supported by the supported event #2 is 3. When event #1 occurs, the number of reported new beams associated with event 1 can be 1 or 2; when event #2 occurs, the number of reported new beams associated with event 2 can be 1, 2 or 3.

[0423] For another example, the terminal device supports event #1 and event #2, and the indication information includes that the maximum number of reported new beams supported by the supported event #1 and event #2 supported by the terminal device is 3. When event #1 occurs, the number of reported new beams associated with event 1 can be 1, 2 or 3; when event #2 occurs, the number of reported new beams associated with event 2 can be 1, 2 or 3.

[0424] The above is an example for illustration, and the embodiments of the present application are not limited thereto. The terminal device can indicate various information related to events supported by the terminal device to the network device.

[0425] Based on the above implementation mode, the first device can obtain configuration information, and perform measurement (such as beam measurement, or channel measurement, etc.) on M cells, and then obtain measurement results (or measurement reports) related to X events corresponding to the M cells. The specific implementation mode of the terminal device for measurement is not limited in the present application, and can be referred to the related description of the current technical solution.

[0426] S520, the first device sends the measurement report to the second device;

[0427] Correspondingly, the second device receives the measurement report from the first device.

[0428] The measurement report includes at least one event-related measurement result corresponding to the M1 cells.

[0429] In the present application, the M1 cells are cells in which events occur, and the at least one event is an event that occurs, that is, at least one event occurs in each of the M1 cells. In other words, the at least one event corresponding to the M1 cells is an event that occurs on the M1 cells, for example, the at least one event corresponding to the M1 cells can be at least one of the event #A to the event #K described above. It can be understood that the occurrence of an event triggers reporting, that is, triggering the measurement report corresponding to the event to be reported.

[0430] Optionally, the measurement result can include but is not limited to whether an event occurs on the M1 cells, whether an event occurs in the M1 cells, the index of the cell in which the event occurs, the index of the event that occurs, the reporting parameter corresponding to the event that occurs, for example, at least one or more of the foregoing reporting parameter #1 to the reporting parameter #11.

[0431] The measurement report, that is, the event-related measurement report, can be understood as: only including at least one event-related measurement result corresponding to the M1 cells, at this time the measurement report does not include the measurement result related to the cell in which no event occurs; or, it can also be understood as: including X event-related measurement results corresponding to the M cells, at this time the measurement result related to the cell in which no event occurs, or the measurement result related to the cell in which the event occurs but is not reported can be filled with a pre-defined value, for example, 0.

[0432] In the present application, the number of measurement reports can be one or more, depending on the number of measurement report configurations configured by the network device or pre-defined by the protocol. It should be understood that one measurement report configuration corresponds to one measurement report. Optionally, the reporting parameter triggered by each event supported on each cell can be pre-defined or pre-configured by the protocol, or can be indicated or configured by the network device through signaling, which is not limited in the present application. For example, when the at least one event-related measurement result corresponding to the M1 cells corresponds to multiple measurement reports, it means that one measurement report can include at least one event-related measurement result of one cell, or one measurement report can include one event-related measurement result of one cell, or one measurement report can include the same event-related measurement result of multiple cells, or one measurement report can include at least one event-related measurement result of multiple cells, etc., and the terminal device reports the measurement result of the at least one event corresponding to the M1 cells through multiple measurement reports. For another example, when the at least one event-related measurement result corresponding to the M1 cells corresponds to one measurement report, the terminal device reports the measurement result of the at least one event corresponding to the M1 cells through one measurement report.

[0433] In one example, M cells correspond to one measurement report configuration, i.e., when at least one event-related measurement result of M1 cells corresponds to one measurement report configuration, the terminal device can sequentially rank the at least one event-related measurement result of the M1 cells according to cell priority ranking information corresponding to the M1 cells, and report through one measurement report.

[0434] In another example, M cells correspond to multiple measurement report configurations, i.e., when at least one event-related measurement result of M1 cells corresponds to multiple measurement report configurations, the terminal device can sequentially rank the at least one event-related measurement result of the M1 cells according to priority ranking information of the multiple measurement report configurations, and report through multiple measurement reports.

[0435] In another example, M cells correspond to multiple measurement report configurations, i.e., when at least one event-related measurement result of M1 cells corresponds to multiple measurement report configurations, the terminal device can sequentially rank the at least one event-related measurement result of the M1 cells according to priority ranking information of the multiple measurement report configurations, and report through multiple measurement reports.

[0436] That is, if the network device configures M cells or M1 cells to correspond to one measurement report configuration, it means that at least one event-related measurement result of the M1 cells is carried in one measurement report, and the specific measurement result can be sequentially ranked and reported according to the reporting priority of the M1 cells. For example, M1 = 3, including cell A, cell B and cell C, wherein the priority of cell A is higher than that of cell B, and the priority of cell B is higher than that of cell C, if the events occurring on cell A, cell B and cell C are event 1, event 2 and event 3 respectively, then in one measurement report, the measurement results corresponding to event 1, event 2 and event 3 are sequentially placed. If the network device configures M1 cells to correspond to multiple measurement report configurations, it means that at least one event-related measurement result of the M1 cells is carried in multiple measurement reports, and the specific measurement result can be sequentially ranked and reported according to the reporting priority of the M1 cells. For example, M1 = 3, including cell A, cell B and cell C, wherein the priority of cell A is higher than that of cell B, and the priority of cell B is higher than that of cell C, the number of measurement reports is 2, wherein measurement report #1 corresponds to cell A and cell B, and measurement report 2 corresponds to cell C, if the events occurring on cell A, cell B and cell C are event 2, event 1, event 3 and event 4 respectively, then in measurement report 1, the measurement results corresponding to event 2 and event 1 are sequentially placed, and in measurement report 2, the measurement results corresponding to event 3 and event 4 are sequentially placed.

[0437] Optionally, the cell priority ordering information corresponding to the M cells or M1 cells can be predefined or preconfigured by a protocol, or can be indicated or configured by the network device, which is not limited in the present application.

[0438] Optionally, the M cells or M1 cells are associated with one or more measurement report configurations, which can be indicated or configured by the network device, or can be predefined by a protocol, which is not limited in the present application.

[0439] Optionally, the terminal device can also not send the measurement results (i.e., event-related reports) associated with the X events that have occurred in the M cells. In other words, an event occurs, but the measurement results do not need to be reported. For example, event A on cell #1 does not need to report the measurement results. Assuming that the measurement results corresponding to event A are not in the measurement report, it is not necessary to send, and only needs to inform the network device that event A on cell #1 has occurred.

[0440] Optionally, the number of cells in which the events have occurred and / or the number of events that have occurred are not limited in the present application. As an example, M1 is equal to 1, and at least one event is one event, i.e., the terminal device can report one cell and / or one measurement result associated with the event that has occurred through the measurement report, which facilitates the management of cells and events.

[0441] Optionally, M1 is equal to 1 and at least one event is one event, i.e., the terminal device reports one measurement result associated with the event that has occurred on one cell, which can be determined in one or more ways, such as being indicated or configured by the network device, or being predefined or preconfigured by a protocol, or being determined by the terminal device according to its own terminal capability, as long as the information of the reported cell and event is aligned between the network device and the terminal device, which is not limited in the present application.

[0442] Optionally, M1 is equal to 1 and at least one event is one event, which can also depend on the capability of the terminal device. For example, assuming that there are Q=6 events occurring on N=4 cells, since the terminal device only supports reporting one measurement result associated with one event occurring on one cell, the terminal device can report one measurement result associated with one event occurring on one cell.

[0443] Optionally, the terminal device can report one or more measurement reports through signaling or reporting resources (or uplink resources). The reporting resources can be the aforementioned event-triggered reporting resources. Optionally, the number of uplink resources carried by the one or more measurement reports sent by the terminal device is not limited in the present application, wherein the one or more measurement reports correspond to one or more measurement report configurations.

[0444] In an implementation, the M cells are associated with multiple measurement reporting configurations, where the multiple measurement reporting configurations can be M or T, T being an integer greater than 1. The multiple measurement reports corresponding to the multiple measurement reporting configurations can be carried on the same uplink resource, so that the at least one event-related measurement result corresponding to the M cells can be carried on the same reporting resource, or in other words, the at least one event-related measurement result corresponding to the M cells is reported through the same uplink resource.

[0445] In another implementation, the M cells are associated with multiple measurement reporting configurations, and the multiple measurement reports corresponding to the multiple measurement reporting configurations can be carried on multiple uplink resources, so that the at least one event-related measurement result corresponding to the M cells is carried on different uplink resources, or in other words, the at least one event-related measurement result corresponding to the M cells is reported through different uplink resources. Alternatively, the at least one event-related measurement result corresponding to at least two cells among the M cells is carried on different uplink resources.

[0446] In yet another implementation, the M cells are associated with multiple measurement reporting configurations, where the M cells are associated with one measurement reporting configuration of the multiple measurement reporting configurations, so that the at least one event-related measurement result corresponding to the M cells can be carried on the same reporting resource, or in other words, the at least one event-related measurement result corresponding to the M cells is reported through the same uplink resource.

[0447] Optionally, the signaling can be MAC CE signaling or UCI signaling. The uplink resource can be a periodic PUCCH resource, an aperiodic PUSCH resource, a semi-persistent PUCCH resource, a semi-persistent PUSCH resource, or the like. The network device can configure only one reporting resource, i.e., each of the M cells corresponds to the same reporting resource, or in other words, all event-triggered reporting configurations correspond to the same reporting resource. Alternatively, the network device can also configure multiple reporting resources, i.e., the M cells correspond to different reporting resources, for example, each cell corresponds to a different reporting resource, or alternatively, at least two cells correspond to different reporting resources, which is not limited in the present application.

[0448] Optionally, for the case that there are N cells in the M cells in which events occur, the total number of events occurring on the N cells can be Q, the N cells include M1 cells, i.e., M1 is less than or equal to N, N is less than or equal to M, which means that the terminal device can report all or part of the cells in which events occur, Q is greater than or equal to the number of at least one event, which means that the terminal device can report all events or part of the events. That is, the number of at least one event occurring in the M1 cells can be less than or equal to Q, and the number of cells in which events occur M1 can be less than or equal to N, which is not limited in the present application.

[0449] Optionally, the terminal device can report the measurement results related to at least one event corresponding to the M1 cells in a predefined or preconfigured first order or a first order determined by the terminal. For example, when multiple events occur in the same cell, the predefined or preconfigured first order can be at least one of the following: in descending order of the index of the event, or in ascending order of the index of the event, or in descending order of the priority of the event, or in descending order of the priority of the measurement report configuration corresponding to the event. Specifically, assuming that Q=2, M1=1, and the events occurring on the N cells include event #m and event #r, the priority of event #m is higher than that of event #r, and when the terminal device reports the measurement results related to the events occurring in the cell, the measurement report related to event #m can be ranked first, and the measurement report related to event #r can be ranked second, or the terminal device can only report the measurement report related to event #m.

[0450] For example, when multiple cells have events occurring, the predefined or preconfigured first order or the first order determined by the terminal can be at least one of the following: in descending order of the priority of the cells, or in descending order of the priority of the measurement report configuration corresponding to the cells, or in descending order of the index of the events in the cell, or in ascending order of the index of the events in the cell, or in descending order of the priority of the events in the cell, or in descending order of the priority of the measurement report configuration corresponding to the events in the cell.

[0451] For example, assuming that there are M=4 cells, such as cell A, cell B, cell C and cell D, wherein cell A supports event 1, cell B supports event 2 and event 3, cell C supports event 1, event 2 and event 3, and cell D supports event 3, event 4 and event 5, i.e., X=9, if the number of cells in which events occur is N=4, it indicates that events occur in each cell, if event 1 occurs in cell A, event 2 occurs in cell B, event 1, event 2 and event 3 occur in cell C, and event 3 and event 5 occur in cell D, the terminal device can send measurement results related to at least one event (i.e., 7 events) corresponding to M1=4 cells, i.e., report the results related to all cells and events in which events occur; or, if the priority of cell A and cell D is higher than that of cell B and cell C, the terminal device can send measurement results related to at least one event (e.g., event 1 in cell A and event 3, event 4 and event 5 in cell D) corresponding to M1=2 cells (e.g., cell A and cell D); or, if the priority of cell A, cell C and cell D is higher than that of cell B, and the priority of event 1 and event 3 in cell C is lower than that of event 2, and the priority of event 4 and event 5 in cell D is lower than that of event 3, the terminal device can send measurement reports related to at least one event (e.g., event 1 in cell A, event 2 in cell C and event 3 in cell D) corresponding to M1=3 cells (e.g., cell A, cell C and cell D), i.e., report measurement results related to part of cells and / or events in which events occur.

[0452] The load size of the measurement report refers to the load size included in the measurement report, or the number of bits / bit space / bit width included in the measurement report, or the space / reserved load size / bit number / bit space / bit width reserved by the measurement report, etc. That is, the space, reported space, bit space, reported bit space, load size, reported load size, bit number, reported bit number, bit width, reported bit width, reported payload size, or payload size, etc. in the present application can be replaced with each other.

[0453] The load size of the measurement report can be a load size required for reporting the measurement result related to the first event, or a load size required for reporting the measurement result related to the first cell, or a load size required for reporting the measurement result related to the first event and the first cell. It can be understood as a load size required for reporting the measurement result related to the first event associated with the first cell, or a load size required for reporting the measurement result corresponding to the first event occurring on the first cell. The M1 cells belong to M cells, and M1 is a positive integer less than or equal to M. Further, the load size required for the measurement result related to the first event and / or the first cell refers to a load size required for reporting the measurement result of the first event and / or the first cell, or a bit number / bit space / bit width required for the measurement result of the first event and / or the first cell. Further, the load size required for reporting the measurement result related to the event refers to a load size (or bit number / bit space / bit width) required for reporting all the reporting parameters corresponding to the reporting number included in the measurement result related to the event, that is, the load size required for reporting the measurement result related to the event is determined by at least one of all the reporting parameters included in the measurement result related to the event and the reporting number of each reporting parameter.

[0454] For example, assuming that the measurement result related to event #m includes reporting parameter #a, reporting parameter #b, …, and reporting parameter #k, and the bit number required for reporting each reporting parameter is Pa, Pb, …, and Pk in turn, the load size required for reporting the measurement result related to event #m is (Pa+Pb+…+Pk). As an example, the measurement result related to event #m includes k reporting parameters #a, l reporting parameters #b, …, and m reporting parameters #k, and the bit number required for reporting each reporting parameter is Pa, Pb, …, and Pk in turn, the load size required for reporting the measurement result related to event #m is (k*Pa+l*Pb+…+m*Pk). The reporting parameter #a, the reporting parameter #b, …, or the reporting parameter #k can be one of the reporting parameters #1 to the reporting parameter #11 described above; or one or more of the reporting parameter #a to the reporting parameter #k can also not be limited to the reporting parameters described above. In this example, the reporting parameters included in the measurement result related to event #m and the reporting number of each reporting parameter can be determined by at least one of network device configuration, protocol specification, terminal capability reporting, etc. It can be understood that the terminal device and the network device determine the measurement result related to the event, and the load size required for reporting the measurement result related to the event can also be determined.

[0455] Optionally, the at least two measurement results corresponding to the at least one event of the M1 cells are different in load size. For example, M1=1, including cell A, the at least one event includes event 1, event 2 and event 3, indicating that the terminal device reports the measurement results of event 1, event 2 and event 3 occurring on cell A by sending a measurement report. Among them, the measurement result corresponding to event 1 has a load size of a, the measurement result corresponding to event 2 has a load size of b, and the measurement result corresponding to event 3 has a load size of c, a, b and c are not equal; or, the measurement results corresponding to event 1 and event 2 have a load size of a, and the measurement result corresponding to event 3 has a load size of b, and a and b are not equal.

[0456] Optionally, if the measurement result corresponding to a certain event in the at least one event of the M1 cells includes a plurality of reporting parameters, the terminal device can report the plurality of reporting parameters corresponding to the certain event according to the reporting order of the reporting parameters. The reporting order of the plurality of reporting parameters can be predefined or preconfigured, or can be indicated or configured by the network device through signaling, which is not limited in the present application. For example, the at least one event corresponding to the M1 cells includes event #1, and the measurement result corresponding to event #1 includes reporting parameter #1 and reporting parameter #2 as described above. According to the predefined or preconfigured reporting order, the terminal device can first report reporting parameter #1 and then report reporting parameter #2, that is, in the reported measurement report, the bit space occupied by reporting parameter #1 is earlier than the bit space occupied by reporting parameter #2.

[0457] Next, the load size of the above measurement report can be: the load size required for reporting the measurement result of the first event and / or the first cell.

[0458] Optionally, the first event can be a predefined event, or an event indicated by the network device to the terminal device, or an event indicated by the terminal device to the network device, or the first event is an event in which the load size of the measurement result is greater than or equal to a threshold value. For example, the first event is the event with the largest load size in the load size required for reporting the measurement result of X events. For example, the X events are event #1, event #2, …, event #X, the load sizes required for the measurement results of event #1, event #2, …, event #X are P1, P2, …, PX, respectively, wherein Pn is the largest in P1 to PX, and event #n is the first event.

[0459] That is, the load size of the measurement report sent by the terminal device is the load size of the largest load of the event related to the measurement result reported in X events, and the load size required by the terminal device to report the measurement result related to at least one event of M1 cells can be less than or equal to the load size of the measurement report. For example, assuming X=3, the load sizes of event 1, event 2 and event 3 are A, B and C, where A < B < C, indicating that the load size of event 3 is the largest, and event 3 is the first event. In addition, if the terminal device reports at least one event on M1=2 cells, for example, event 1 on cell A and event 2 on cell B meet the event reporting condition, if A+B≤C, the terminal device reports the measurement result corresponding to event 1 on cell A and event 2 on cell B; if A+B>C, A < C and B < C, the terminal device can report the measurement result corresponding to event 1 on cell A or the measurement result corresponding to event 1 on cell B. Alternatively, if the reporting priority of cell A is higher than that of cell B, the terminal device reports the measurement result corresponding to event 1 on cell A.

[0460] Alternatively, the first cell can be a predefined cell, or a cell indicated by the network device to the terminal device, or a cell indicated by the terminal device to the network device, or the first cell is a cell whose load size required for reporting the measurement result related to M cells is greater than or equal to a threshold, for example, the first cell is a cell whose load size required for reporting the measurement result related to M cells is the largest. For example, the load sizes required for reporting the measurement results related to M cells are Q1, Q2, …, QM, respectively, where Qy is the largest among Q1 to QM, and cell M is the first cell.

[0461] That is, the corresponding load size of the measurement report sent by the terminal device is the sum of the load sizes required for reporting the measurement results of the M cells, and the load size required for the terminal device to report the measurement results of at least one event corresponding to the M1 cells can be less than or equal to the load size of the measurement report. For example, assuming that M = 3, the load sizes of the cells A, B and C are a, b and c, and a < b < c, which indicates that the load size of the cell C is the largest, and the cell C is the first cell, that is, the load size of the measurement report reported by the terminal device is c. At this time, if the terminal device reports at least one event on the M1 = 2 cells, for example, event 1 on the cell A and event 1 and event 2 on the cell B, and the load sizes corresponding to the events 1 and 2 are A and B, then the load size corresponding to the at least one event of the M1 cells reported by the terminal device is 2A + B ≤ c.

[0462] Alternatively, assuming that the first cell is one of the M cells, the load size of the measurement report reported by the terminal device is the sum of the load sizes required for reporting the measurement results of the M cells.

[0463] That is, the corresponding load size of the measurement report sent by the terminal device is the sum of the load sizes required for reporting the measurement results of the M cells, and the load size required for the terminal device to report the measurement results of at least one event corresponding to the M1 cells can be less than or equal to the load size of the measurement report. For example, assuming that M = 3, the load sizes of the cells A, B and C are a, b and c, and a < b < c, which indicates that the load size of the cell C is the largest, and the cell C is the first cell, that is, the load size of the measurement report reported by the terminal device is c. At this time, if the terminal device reports at least one event on the M1 = 2 cells, for example, event 1 on the cell A and event 1 and event 2 on the cell B, and the load sizes corresponding to the events 1 and 2 are A and B, then the load size corresponding to the at least one event of the M1 cells reported by the terminal device is 2A + B ≤ c.

[0464] In the following, the relationship between the load size of the measurement report reported by the terminal device and the load size required by the at least one event-related measurement result corresponding to the M1 cells is exemplarily described in connection with the following multiple scenarios.

[0465] Scenario one:

[0466] Suppose the load size required by the at least one event-related measurement result corresponding to the M1 cells is smaller than the load size of the measurement report, then the part of the measurement report other than the at least one event-related measurement result corresponding to the M1 cells is filled with predefined values.

[0467] As an example, the rest of the bits in the measurement report other than the bits required to carry the at least one event-related measurement result corresponding to the M1 cells are filled with 0. For example, the load size of the measurement report is S bits, the load size required by the at least one event-related measurement result corresponding to the M1 cells is L bits, if L < S, the first L bits of the measurement report are used to carry the at least one event-related measurement result corresponding to the M1 cells, and the remaining bits are filled with 0, S and L are positive integers; as another example, the load size of the measurement report is S bits, the at least one event-related measurement result corresponding to the M1 cells contains reporting parameter #a and reporting parameter #b, the number of bits required by reporting parameter #a and reporting parameter #b is Pa and Pb respectively, if (Pa+Pb) < S, the first (Pa+Pb) bits of the measurement report are used to carry the at least one event-related measurement result corresponding to the M1 cells, and the remaining bits are filled with 0. Wherein, the reporting parameter #a and the reporting parameter #b can be one or more of the reporting parameters #1 to #11 described above.

[0468] Optionally, if the at least one event-related measurement result corresponding to the M1 cells contains one or more reporting parameters, and the reporting parameter #f in the one or more reporting parameters corresponds to a reporting number less than the maximum reporting number of the reporting parameter #f specified by the network device or protocol, the part of the measurement report corresponding to the reporting parameter #f, except for the reporting parameter #f contained in the at least one event-related measurement result corresponding to the M1 cells, is a predefined value. The reporting parameter #f can be one of the reporting parameters #1 to #11 described above. For example, the reporting parameter #f is the reporting parameter #3 described above, i.e., the index of the second beam, and the network device or protocol specifies that the maximum value of the number of beams included in the second beam is 4. In this case, the number of bits Pf corresponding to the reporting parameter #f in the measurement report can be used to carry the indexes of 4 beams, and the at least one event-related measurement result corresponding to the M1 cells contains the indexes of 2 beams, which require a number of bits of Pf / 2. Therefore, Pf / 2 bits of the Pf bits corresponding to the reporting parameter #f in the at least one event-related measurement result corresponding to the M1 cells carry the reporting parameter #f contained in the at least one event-related measurement result corresponding to the M1 cells, and the other Pf / 2 bits are filled with 0.

[0469] Case two:

[0470] For example, there can be N cells in the M cells that are event cells, and the total number of events occurring on the N cells can be Q. There can be at least two cells on which the same event occurs, and the N cells include the M1 cells.

[0471] Suppose the load size required by the Q event-related measurement results corresponding to the N cells is greater than the load size of the measurement report, then the measurement report includes at least one event-related measurement result corresponding to part of the Q event-related measurement results corresponding to the N cells, for example, at least one event-related measurement result corresponding to the M1 cells.

[0472] As an example, the load size of the measurement report is S bits, the load size of the Q event-related measurement results corresponding to the N cells is L bits, if L > S, the measurement report can carry at least one event-related measurement result corresponding to M1 cells, the load size of the measurement result is S1, and S1≤S at this time. Alternatively, the terminal device can report according to the cell priority ranking information corresponding to the M1 cells. For example, there are cell 1, cell 2 and cell 3, the load size of the event-related measurement result occurring on the cell 1 is L1, the load size of the event-related measurement result occurring on the cell 2 is L2, the load size of the event-related measurement result occurring on the cell 3 is L3, the priority of the cell 3 is higher than the priority of the cell 1, and the priority of the cell 1 is higher than the priority of the cell 2. Since L1+L2+L3>L and L1+L3<L, the terminal device can report the event-related measurement results occurring on the cell 3 and the cell 1 in turn in the measurement report.

[0473] Case three:

[0474] Suppose the load size of at least one event-related measurement result corresponding to M1 cells is equal to the load size of the measurement report, the measurement report includes all the at least one event-related measurement result corresponding to M1 cells, i.e. no need to fill in the pre-defined value. In other words, the terminal device can report the at least one event-related measurement result corresponding to M1 cells according to the pre-defined or pre-configured reporting order.

[0475] As an example, suppose there are Q events corresponding to N cells, the load size of the Q event-related measurement results corresponding to the N cells is greater than the load size of the measurement report, the measurement report includes part of the Q event-related measurement results corresponding to the N cells, for example, the measurement report includes at least one event-related measurement result corresponding to M1 cells, and the load size of the at least one event corresponding to M1 cells is equal to the load size of the measurement report.

[0476] For example, the terminal device can drop part of the Q event-related measurement results corresponding to the N cells according to the pre-defined or pre-configured reporting order. Suppose the load size of the measurement report is S bits, the load size of the Q event-related measurement results corresponding to the N cells is L' bits, if L'>S, the terminal device drops the last (L'-S) bits of the Q event-related measurement results corresponding to the N cells, and reports the first S bits of the Q event-related measurement results corresponding to the N cells through the measurement report, for example, the first S bits are equal to the load size of the measurement result of at least one event corresponding to M1 cells, and L' is a positive integer.

[0477] For example, the payload size of the measurement report is S bits, the Q event-related measurement results corresponding to the N cells contain the reporting parameter #c, the reporting parameter #d and the reporting parameter #e, the number of bits required by the reporting parameter #c, the reporting parameter #d and the reporting parameter #e is Pc, Pd and Pe respectively, if (Pc+Pd+Pe) > S, the terminal device reports part of the reporting parameter #c, the reporting parameter #d and the reporting parameter #e through the measurement report according to the pre-defined or pre-configured reporting order. For example, the reporting order of the reporting parameter #c and the reporting parameter #d is in the front, and (Pc+Pd) ≤ S, (Pc+Pd+Pe) > S, the terminal device drops the reporting parameter #e, and reports the reporting parameter #c and the reporting parameter #d through the measurement report, or the terminal device discards the last (S-Pc-Pd) bits of the reporting parameter #e, and reports the first (Pc+Pd+Pe-S) bits of the reporting parameter #c, the reporting parameter #d and the reporting parameter #e through the measurement report. Wherein, the reporting parameter #c, the reporting parameter #d and the reporting parameter #e can be one or more of the reporting parameter #1 to the reporting parameter #11 described above.

[0478] Next, the payload size required by the terminal device to determine at least one event-related measurement result corresponding to M1 cells, and the reporting manner of the measurement report are exemplarily described.

[0479] Case one: one measurement report is configured to be associated with M cells, that is, M cells are associated with one measurement report, at this time the terminal device can report the measurement result of at least one event corresponding to M1 cells through one measurement report, which includes the following steps. Optionally, M and M1 are integers greater than or equal to 1, and M1 is less than or equal to M.

[0480] Step 1: determine the payload size required by the measurement result related to one event in X events.

[0481] Method one: report with fixed payload size.

[0482] Exemplarily, the terminal device determines the reporting parameter corresponding to one event in X events, and the reporting number of each reporting parameter. Wherein, one or more reporting parameters corresponding to one event in X events, and the maximum reporting number corresponding to each reporting parameter can be pre-defined or pre-configured, can be indicated by the network device through signaling, or can be determined by the terminal device, which is not limited. Correspondingly, the terminal device reserves the reporting space corresponding to the event according to the maximum reporting number of each reporting parameter determined by at least one of the configuration, the pre-definition and the terminal capability. The reporting space is the sum of the product of the maximum reporting number corresponding to each reporting parameter of the event and the payload size required by each reporting parameter.

[0483] For example, assume that one event (e.g., event #1) occurs in one of the M cells, which can be one of the events #A to #K in step S501. If the corresponding reporting parameter when the event #1 occurs includes the reporting parameter #x, the reporting parameter #x can be any one of the aforementioned reporting parameters #1 to #11. Assume that the load size required for reporting one reporting parameter #x is a, if k reporting parameter #x need to be reported when the event #1 occurs, the load size required for the terminal device to report the measurement result related to the event #1 is a*k. For another example, assume that two events (e.g., event #2 and event #3) occur in one of the M cells, which can be one of the events #A to #K in step S501. If the corresponding reporting parameter when the event #2 occurs includes the reporting parameter #y and the reporting parameter #z, the reporting parameter #y and the reporting parameter #z can be any one of the aforementioned reporting parameters #1 to #11. The number of reporting parameter #y and the reporting parameter #z that need to be reported when the event #2 occurs are m and n respectively, the corresponding reporting parameter of the event #3 includes the reporting parameter #y and the reporting parameter #f, the reporting parameter #y and the reporting parameter #f can be any one of the aforementioned reporting parameters #1 to #11. The number of reporting parameter #y and the reporting parameter #f that need to be reported when the event #3 occurs are f and g respectively, the load sizes required for the reporting parameter #y, the reporting parameter #z and the reporting parameter #f are a, b and c respectively, the load size required for reporting the measurement result related to the event #2 is a*m+b*n, the load size required for reporting the measurement result related to the event #3 is b*f+c*g. The k, m, n, f and g are positive integers.

[0484] Optionally, if the number of reporting of a reporting parameter that satisfies the event occurrence condition is less than the maximum number of reporting of the reporting parameter configured by the network side, the terminal device can report the remaining space in any of the following ways.

[0485] (1) filling with a predefined value, for example, filling with 0;

[0486] (2) reporting the corresponding measurement quantity corresponding to the reporting parameter that does not satisfy the event condition;

[0487] (3) repeatedly reporting the measurement quantity corresponding to the reporting parameter that satisfies the event condition;

[0488] (4) reporting the measurement quantity corresponding to other reporting parameters.

[0489] For example, the number of reporting parameters #x satisfying the condition of event #1 (e.g., 3) is less than the maximum number of reporting parameters #x configured by the network side (e.g., 4), when event #1 occurs, the terminal device can report the measurement quantity of 3 reporting parameters #x satisfying the condition of event #1, and can report the empty space (i.e., the remaining 1 reporting parameter #x corresponding to the reporting space) in any of the following ways:

[0490] (1) Fill in a predefined value, for example, fill in 0;

[0491] (2) Report the measurement quantity corresponding to the reporting parameter #x that does not satisfy the event condition, that is, report 1 reporting parameter #x that does not satisfy the condition of event #1;

[0492] (3) Repeat the reporting of the measurement quantity corresponding to the reporting parameter #x that satisfies the event condition, that is, report any one of the 3 reporting parameters #x that satisfy the condition of event #1.

[0493] (4) Report the measurement quantity corresponding to other reporting parameters, for example, report the measurement quantity corresponding to reporting parameter #y.

[0494] For example, assuming that the reporting parameters corresponding to event q include reporting parameter #3 (e.g., second beam index) and reporting parameter #4 (e.g., second beam quality), the maximum number of reporting parameters #3 and reporting parameter #4 is N3 and N4, for example, N3 = 3, N4 = 3; When the number of second beams satisfying the condition of event q is N1, for example, N1 = 2, then the terminal device can report N1 second beam indexes and their corresponding N1 second beam qualities, for the empty N3-N1 second beam index and N4-N1 second beam quality corresponding positions, the terminal device can fill in a special value (e.g., all 0); Or, the terminal device can report N3 second beam indexes and their corresponding N4 second beam qualities, of which N1 second beam indexes and their corresponding N1 second beam qualities satisfy the condition of event q, and the other N3-N1 second beam indexes and their corresponding N4-N1 second beam qualities do not satisfy the condition of event q; Or, the terminal device can select N3-N1 second beam indexes and their corresponding N4-N1 second beam qualities from the N1 second beam indexes and their corresponding N1 second beam qualities that satisfy the event condition for repeated reporting; Or, the terminal device can report N3-N1 service beam indexes and corresponding N4-N1 service beam qualities. It can be understood that the event q in the example of the present application can be one of events #A to #K in step S501.

[0495] In an implementation, the load size required for reporting the measurement result of each event in X events can be determined according to the corresponding reporting parameter and the number of reporting of the corresponding reporting parameter.

[0496] Taking event q in X events as an example, it is assumed that the reporting parameters corresponding to event q include reporting parameter #x and reporting parameter #y, the reporting parameter #x or the reporting parameter #y can be any one of the foregoing reporting parameters #1 to #11, the load sizes required for the measurement quantities of the reporting parameter #x and the reporting parameter #y are Pa and Pb respectively, if the network device configures or the protocol stipulates that the number of reporting of the reporting parameter #x and the reporting parameter #y is Na and Nb respectively, when event q occurs, the load size required for the terminal device to report the measurement result related to event q is S = Pa*Na+Pb*Nb.

[0497] Optionally, the following example is described in combination with FIG. 6, for the number of reporting of the reporting parameter #1 meeting the event q condition being less than N1 and the number of reporting of the reporting parameter #2 meeting the event q condition being less than N2, n and m are both integers greater than or equal to 1.

[0498] FIG. 6 is a structural schematic diagram of the terminal device reporting the measurement quantity of the reporting parameter meeting the event q condition according to an embodiment of the present application. As shown in FIG. 6, when event q occurs in one cell, the reporting parameters corresponding to event q include reporting parameter #1 and reporting parameter #2, the load sizes required for the measurement quantities of the reporting parameter #1 and the reporting parameter #2 are P1 and P2 respectively, if the network device configures the number of reporting of the reporting parameter #1 as N1 and the number of reporting of the reporting parameter #2 as N2, if the number of measurement quantities corresponding to the reporting parameter #1 meeting the event q condition is n, the number of measurement quantities corresponding to the reporting parameter #2 meeting the event q condition is m, n < N1 and m < N2, then the load size required for the terminal device to report the measurement result related to event q is S = P1*N1+P2*N2. As can be known from FIG. 6, the terminal device reports the measurement quantity of n reporting parameter #1 meeting the event q condition and the measurement quantity of m reporting parameter #2 meeting the event q condition, for the remaining space size of P1*(N1-n) corresponding to the reporting parameter #1, a special value can be filled, or the measurement quantity of the reporting parameter #1 not meeting the event q condition is reported, or the measurement quantity of the reporting parameter #1 meeting the event q condition is repeatedly reported. Similarly, for the remaining space size of P2*(N2-m) corresponding to the reporting parameter #2, a special value can be filled, or the measurement quantity of the reporting parameter #2 not meeting the event q condition is reported, or the measurement quantity of the reporting parameter #2 meeting the event q condition is repeatedly reported.

[0499] Optionally, the number n of the reporting parameter #1 satisfying the event q condition is greater than or equal to N1, and the number m of the reporting parameter #2 satisfying the event q condition is greater than or equal to N2, where n and m are integers greater than or equal to 1. If n is equal to N1 and m is equal to N2, the terminal device reports the measurement quantity of the n reporting parameter #1 satisfying the event q condition and the measurement quantity of the m reporting parameter #2 satisfying the event q condition, and the required load size for reporting the measurement result related to the event q is S = P1*N1 + P2*N2. If n is greater than N1 and m is greater than N2, the terminal device can report the measurement quantity of the N1 reporting parameter #1 satisfying the event q condition and the measurement quantity of the N2 reporting parameter #2 satisfying the event q condition in a predefined or preconfigured order, and the measurement quantity of the n-N1 reporting parameter #1 satisfying the event q condition and the measurement quantity of the m-N2 reporting parameter #2 satisfying the event q condition are not reported (or discarded), and the required load size for reporting the measurement result related to the event q is S = P1*N1 + P2*N2.

[0500] Method two: flexible load size reporting.

[0501] For example, the terminal device indicates to the network device the reporting number of each reporting parameter corresponding to a certain event, and reports the corresponding reporting parameter according to the reporting number. For example, the required load size for reporting the measurement result related to each event in X events can be determined according to the reporting number of each reporting parameter corresponding to the event indicated by the terminal device to the network device.

[0502] For example, the event q in X events, assuming that the reporting parameters corresponding to the event q include the reporting parameter #a, the reporting parameter #b and the reporting parameter #c, the reporting parameter #a, the reporting parameter #b and the reporting parameter #c can be any one of the foregoing reporting parameter #1 to reporting parameter #11. The required load sizes of the reporting parameter #a, the reporting parameter #b and the reporting parameter #c are Pa, Pb and Pc respectively. If the numbers of the reporting parameter #a, the reporting parameter #b and the reporting parameter #c satisfying the event q condition are n, m and h respectively, when the event q occurs, the terminal device indicates to the network device the numbers n, m and h of the reporting parameter #a, the reporting parameter #b and the reporting parameter #c satisfying the event q condition respectively, and the required load size for reporting the measurement result related to the event q by the terminal device is S = Pa*n + Pb*m + Pc*h. The event q can be one of the event #A to event #K in the foregoing step S501.

[0503] Optionally, the terminal device reports the number of each reporting parameter corresponding to the event through a first part of a measurement report, CSI Part 1. Specifically, it can be understood that: a measurement report can include a first part, CSI Part 1, and a second part, CSI Part 2. For example, the first part includes one or more of the following: the number of one or more reporting parameters corresponding to the event. The size of the load corresponding to the second part is determined according to the first part. Wherein, the size of the load corresponding to the second part is determined according to the first part, which can be understood as: determining the size of the load of the second part according to the number of one or more reporting parameters corresponding to the event reported in the first part.

[0504] As shown in Table 1, taking the occurrence of event q as an example, the reporting parameters corresponding to event q include reporting parameter #a and reporting parameter #b, and reporting parameter #a or reporting parameter #b can be any one of the foregoing reporting parameters #1-#11. The required load size corresponding to reporting parameter #a and reporting parameter #b is Pa and Pb, respectively. The number of reporting parameter #a and reporting parameter #b corresponding to the event q condition is x and y, respectively. The required load size of the terminal device for reporting the measurement result related to event q is S=Pa*x+Pb*y. Therefore, one measurement report reported by the terminal device includes CSI part 1 and CSI part 2, wherein the CSI part 1 carries the number x of reporting parameter #a and the number y of reporting parameter #b corresponding to event q, the CSI part 2 carries the measurement quantity corresponding to x reporting parameter #a, and the measurement quantity corresponding to y reporting parameter #b, and the size of the load corresponding to the CSI part 2 is the sum of the size of the load corresponding to the measurement quantity corresponding to x reporting parameter #a and the size of the load corresponding to the measurement quantity corresponding to y reporting parameter #b, i.e., the payload size corresponding to the CSI part 2 is S=Pa*x+Pb*y, or in other words, the required load size of the measurement result related to event q is S=Pa*x+Pb*y.

[0505] Table 1

[0506] Optionally, the terminal device reports the number of each reporting parameter corresponding to the event through scheduling request signaling or reporting indication signaling. Specifically, it can be understood that the terminal device determines that an event occurs, initiates scheduling request signaling or reporting indication signaling to the network device, which is used to indicate that the reporting triggered by the event needs to be reported, or is used to indicate that the uplink resource is requested to carry the reporting triggered by the event, or is used to indicate whether the event occurs. The scheduling request signaling or reporting indication signaling can include at least one of the following information: the number of one or more reporting parameters corresponding to each event. The terminal device can determine the reporting space of the reporting triggered by the event according to the scheduling request signaling or reporting indication signaling, that is, determine the reporting space according to the number of one or more reporting parameters corresponding to the event carried by the scheduling request signaling or reporting indication signaling.

[0507] As shown in Tables 2 and 3, taking the occurrence of event q as an example, the reporting parameters corresponding to event q include reporting parameter #a and reporting parameter #b, and the reporting parameter #a or the reporting parameter #b can be any one of the foregoing reporting parameters #1-#11. The number of reporting parameter #a and reporting parameter #b corresponding to the event q condition is x and y respectively, so the terminal device can send the scheduling request signaling or reporting indication signaling in the form of Table 2, and the scheduling request signaling or reporting indication signaling includes the number x of reporting parameter #a and the number y of reporting parameter #b corresponding to event q. In addition, the terminal device can also report the measurement quantity corresponding to x reporting parameter #a and the measurement quantity corresponding to y reporting parameter #b in the form of Table 3. Since the required load size of reporting parameter #a and reporting parameter #b is Pa and Pb respectively, the required load size of the terminal device for reporting the measurement result related to event q is S=Pa*x+Pb*y.

[0508] Optionally, Tables 2 and 3 can be combined or implemented independently, without limitation.

[0509] Table 2

[0510] Table 3

[0511] Exemplarily, the terminal device indicates to the network device the required load size for reporting the measurement result related to one event. For example, the required load size for reporting the measurement result related to each event in X events can be determined according to the required load size of the measurement result related to the corresponding event indicated by the terminal device to the network device.

[0512] Optionally, the payload size required by the event-related measurement result can be carried in a first part of the measurement report, and the payload size of the event-related measurement result carried in a second part of the measurement report is determined according to the payload size of the event-related measurement result indicated in the first part of the measurement report.

[0513] Optionally, the payload size required by the event-related measurement result can be carried in scheduling request signaling or reporting indication signaling, and the payload size of the event-related measurement result carried in the measurement report is determined according to the payload size of the event-related measurement result indicated in the scheduling request signaling or reporting indication signaling.

[0514] Step 2: Determine the payload size required by the event-triggered measurement result of one of the M cells (or CCs).

[0515] Method 1: Report using a fixed payload size.

[0516] In an example, taking one of the M cells as an example, the payload size required for reporting the event-triggered measurement result of the one cell can be the payload size corresponding to the event with the largest required payload size among one or more events supported by the one cell. The payload size required by an event can be understood as the payload size required for reporting the event-related measurement result when the event occurs.

[0517] That is, the payload size required for reporting the event-triggered measurement result of one of the M cells is determined according to the event with the largest required payload size among one or more events supported by the one cell.

[0518] For example, the network device configures, and / or the terminal device determines, and / or the protocol specifies that the terminal device is associated with K events for one cell (e.g., cell #1), respectively event 1, event 2, …, event K, and the payload sizes required for reporting the measurement results related to each event are P1, P2, …, PK, respectively. P1, P2, …, PK can be determined according to the aforementioned step 1, which is not described here. Assuming that the payload size required by the event n among the K events is the largest Pn, when at least one event occurs on the cell #1, the terminal device determines that the payload size required for reporting the event-triggered measurement result related to the cell #1 is Z = Pn. The event 1, event 2, …, event K in the example of the present application can be any one of the event #A to event #K in the aforementioned step S501.

[0519] Optionally, if one or more events occur on the cell #1, when the size of the load required for reporting the measurement results related to the one or more events is smaller than Z, the remaining positions can be filled with special values, for example, all 0, and the size of the load is Z-x; when the size of the load required for reporting the measurement results related to the one or more events is larger than Z, the excess part can be discarded according to the pre-defined priority order.

[0520] In another example, taking one of the M cells as an example, the size of the load required for reporting the measurement results related to the one cell can be the sum of the size of the load required for reporting the measurement results related to each event on the one cell, i.e., the sum of the size of the load required for all events on the one cell.

[0521] That is, the size of the load required for reporting the measurement results related to one of the M cells is determined according to the sum of the size of the load required for all events supported by the one cell.

[0522] For example, the network device configures, and / or the terminal device determines, and / or the protocol specifies that the K events associated with one cell (for example, cell #1) of the terminal device are event 1, event 2, …, event K, respectively, and the size of the load required for reporting the measurement results related to each event is P1, P2, …, PK, respectively, wherein P1, P2, …, PK can be determined according to the aforementioned step 1, which is not described here, and the terminal device determines that the size of the payload required for reporting the measurement results triggered by the event related to the cell #1 is Z = P1+P2+…+PK.

[0523] Optionally, if all the K events occur, the terminal device can report the measurement results related to the K events of the cell #1 in the order of reporting specified by the protocol for each event (for example, the event index is from small to large or from large to small, or other specified order), and the order of reporting of the reporting parameters corresponding to each event.

[0524] Optionally, when one of the K events (for example, event 1) occurs, the measurement results related to the event 1 are reported; when one of the K events (for example, event 2) does not occur, the reporting position corresponding to the event 2 can be filled with a pre-defined value (for example, 0), and the length of the pre-defined value is the size of the load required for the measurement results related to the event 2. That is, the positions corresponding to the events that occur in the K events are filled with the measurement results of the corresponding events that occur, and the positions corresponding to the events that do not occur are filled with pre-defined values (for example, 0).

[0525] Optionally, when one of the K events (e.g., event 1) occurs, the measurement result related to the event 1 is reported; when one of the K events (e.g., event 2) does not occur, the reporting position corresponding to the event 2 can report the measurement result related to the event 2, but none of the measurement results satisfies the condition of the event 2. That is, the position corresponding to the event occurring in the K events is filled with at least one measurement result satisfying the event, and the position corresponding to the event not occurring is filled with the measurement result not satisfying the condition of the event.

[0526] As shown in Table 4 below, assuming that the terminal device associates K events with cell #1, respectively event 1, event 2, …, event K, and the payload size required for reporting the measurement result related to each event is P1, P2, …, PK, respectively, the payload size Z required for the measurement result reported by the event trigger of the cell #1 related event is P1+P2+…+PK, if event 2 does not occur and the other events occur, the reporting position corresponding to the event 2 can be filled with 0, and the length of the 0 is the payload size required for the measurement result related to the event 2, and the other reporting positions are filled with the measurement result related to the event (e.g., event 1, event 3, …, event K) occurring.

[0527] Table 4

[0528] In yet another example, taking one of the M cells as an example, the payload size required for reporting the measurement result related to the one cell can be: the payload size required for the union of all reporting parameters corresponding to all events supported by the one cell.

[0529] For example, the network device configures, and / or the terminal device determines, and / or the protocol specifies that the K events associated with one cell (e.g., cell #1) of the terminal device are event 1, event 2, …, event K, respectively, and the union of the reporting parameters corresponding to all the events is reporting parameter #a, reporting parameter #b, …, reporting parameter #j, that is, at least one event exists reporting parameter #a, reporting parameter #b, …, reporting parameter #j, and the reporting parameters #a, #b, …, #j in the example of the present application can be any one of the aforementioned reporting parameters #1-#11, and the payload size required for reporting each reporting parameter is Xa, Xb, … Xj, respectively. When at least one event exists reporting parameter #a, the maximum value of the maximum reporting number of reporting parameter #a corresponding to all events in the at least one event is denoted as Na. It can be understood that, for example, only event 1 and event 2 corresponding to the K events contain reporting parameter #a, the maximum reporting number of reporting parameter #a corresponding to event 1 is 2, and the maximum reporting number of reporting parameter #a corresponding to event 1 is 3, then the maximum value of the maximum reporting number of reporting parameter #a can be called Na=3. By analogy, the maximum values of the maximum reporting numbers of reporting parameters #a, #b, …, #j are Na, Nb, …, Nj, respectively. Then the payload size required for the terminal device to determine the measurement result triggered by the event reporting of the cell #1 is: S=Xa*Na+Xb*Nb+…+Xj*Nj. That is, if event m and event n in the K events correspond to the same reporting parameter, then the one or more measurement quantities corresponding to the reporting parameter can be reported only once without repeated reporting.

[0530] Optionally, if the K events all occur, the terminal device can report the measurement quantities of each reporting parameter in the order of the reporting sequence of each reporting parameter (i.e., reporting parameter #a, reporting parameter #b, …, reporting parameter #j) specified by the protocol.

[0531] Optionally, when any event corresponding to a certain reporting parameter does not occur, the reporting position of the reporting parameter corresponding to the event can be filled with a predefined value (e.g., 0), and the length of the filled predefined value is the payload size required for the measurement quantity of the reporting parameter, or the measurement quantity of the reporting parameter that does not meet the event condition can also be filled. When at least one event corresponding to a certain reporting parameter occurs, the measurement quantity of the reporting parameter is reported once. Further, when the maximum reporting number of the reporting parameter corresponding to the event is less than the maximum value of the reporting parameter, the measurement quantity corresponding to the reporting parameter that does not meet the event condition can be filled with a predefined value (e.g., 0).

[0532] As shown in Table 5, assuming that the network device configures, and / or the terminal device determines, and / or the protocol stipulates, K events associated with cell #1 of the terminal device are event 1, event 2, …, event K respectively, the union of the reporting parameters corresponding to all the events is reporting parameter #a, reporting parameter #b, …, reporting parameter #j, the payload size required for reporting each reporting parameter is Xa, Xb, … Xj respectively, and the maximum value of the maximum number of each reporting parameter is Na, Nb, …, Nj, then the payload size required for the terminal device to determine the measurement result of the event triggered reporting related to cell #1 is S = Na*Xa+Nb*Xb+…+Nj*Xj. If any event corresponding to reporting parameter #j does not occur, and at least one event corresponding to other reporting parameters occurs, then the reporting position of reporting parameter #j can be filled with 0, and the length of the filled 0 is the payload size required for reporting parameter #j, that is, Xj bits. The other reporting positions are filled with the measurement quantity of the reporting parameter related to the event (for example, reporting parameter #1, reporting parameter #2, …), and the corresponding payload size is Xa bits, Xb bits, …, respectively. Further, when the maximum number of the reporting parameter corresponding to the event is less than the maximum value of the reporting parameter, a pre-defined value (for example, 0) can be filled or the measurement quantity of the reporting parameter corresponding to the event that does not meet the event condition is filled. For example, when only event 1 occurs for the event containing reporting parameter #a, the maximum number of reporting parameter #a corresponding to event 1 is 2, and the maximum value of the maximum number of reporting parameter #a is Na = 3, then 3*Xa bits are filled with 0 or the measurement quantity of reporting parameter #a corresponding to the event that does not meet the event condition.

[0533] Table 5

[0534] Method two: reporting with flexible payload size.

[0535] Exemplarily, taking one of M1 cells as an example, the terminal device can send second information to the network device, the second information being used to indicate event information of at least one event occurring in the one cell or event information requiring reporting of related measurement results; and / or, the reporting number of each reporting parameter corresponding to each event occurring. That is, the terminal device indicates the information of the event occurring in the one cell to the network device, and reports the measurement result related to the event occurring, and then the payload size required for the measurement result triggered by the event in the one cell is determined by the information of the event occurring in the one cell and / or the reporting number of each reporting parameter corresponding to each event occurring. In the present application, the event occurring can be understood as the event occurring and reporting related measurement result, or the event meeting the event condition.

[0536] Optionally, the application does not limit the sending order of the second information and the measurement report, which can be sending the second information first and then sending the measurement report, or sending the measurement report first and then sending the second information, or sending the second information and the measurement report at the same time.

[0537] For example, the network device configures, and / or the terminal device determines, and / or the protocol stipulates that the K events associated with one cell (e.g. cell #1) of the terminal device are event 1, event 2, …, event K respectively, and the payload size required for reporting the measurement result related to each event is P1, P2, …, PK respectively, wherein P1, P2, …, PK can be determined according to the aforementioned step one, which is not described here. When event p and event q in the K events occur, the terminal device reports the index information of event p and event q, and / or the reporting number of each reporting parameter corresponding to event p and the reporting number of each reporting parameter corresponding to event q, and the payload size required for reporting the measurement result related to event p and event q is Pp and Pq respectively, then the terminal device determines the payload size required for reporting the measurement result triggered by the event associated with the cell #1 as: Z = Pp + Pq.

[0538] Optionally, the information of the occurred event, or the event information (e.g. the index information of event p and event q) requiring reporting the related measurement result, and / or the reporting number of each reporting parameter corresponding to each occurred event, can be carried in the scheduling request signaling or the reporting indication signaling, and the payload size required for reporting the measurement result triggered by the event associated with the cell #1 by the terminal device is: S = Pp + Pq.

[0539] As shown in Table 6 and Table 7, taking the occurrence of event p and event q in K events associated with one cell (e.g. cell #1) of the terminal device as an example, the reporting parameters corresponding to event p include reporting parameter #a and reporting parameter #b, the number of reporting parameter #a and reporting parameter #b satisfying the condition of event p is x and y respectively, the reporting parameters corresponding to event q include reporting parameter #c and reporting parameter #d, the number of reporting parameter #c and reporting parameter #d satisfying the condition of event q is m and n respectively, the reporting parameter #a or reporting parameter #b or reporting parameter #c or reporting parameter #d can be any one of the foregoing reporting parameter #1 to reporting parameter #11, x, y, m and n are positive integers, therefore the terminal device can send the scheduling request signaling or the reporting indication signaling in the form of Table 6, the scheduling request signaling or the reporting indication signaling includes the index information of event p, the number x of reporting parameter #a and the number y of reporting parameter #b corresponding to event p, and the index information of event q, the number m of reporting parameter #c and the number n of reporting parameter #d corresponding to event q. In addition, the terminal device can also report the measurement quantity corresponding to x reporting parameter #a of event p and the measurement quantity corresponding to y reporting parameter #b of event p, and report the measurement quantity corresponding to m reporting parameter #c of event q and the measurement quantity corresponding to n reporting parameter #d of event q in the form of Table 7. Since the required load size of reporting parameter #a, reporting parameter #b, reporting parameter #c and reporting parameter #d is Pa, Pb, Pc and Pd respectively, the required load size of the terminal device for reporting the measurement results related to event p and event q is S = Pa*x + Pb*y + Pc*m + Pd*n.

[0540] Optionally, the scheduling request signaling or the reporting indication signaling in Table 5 can only include the index information of event p and event q, without reporting the number of reporting parameters corresponding to the occurred events, for example, the number of each reporting parameter corresponding to event p and event q.

[0541] Optionally, Table 6 and Table 7 can be combined or implemented independently, without limitation.

[0542] Table 6

[0543] Table 7

[0544] Optionally, the information of the occurred events, or the event information (e.g., the index information of the events p and q) requiring to report the related measurement results, and / or the reporting number of each reporting parameter corresponding to each occurred event, can be carried in a CSI part 1 of a measurement report (CSI Report), and the measurement quantity corresponding to each reporting parameter of the events p and q can be carried in a CSI part 2 of the measurement report, and then the payload size required by the terminal device to report the measurement results triggered by the event of the cell #1 is S = Pp+Pq+N, N is the bit number required by the reporting information of the occurred events and / or the reporting number of each reporting parameter corresponding to each occurred event, wherein the load size in the CSI part 1 is N, and the load size of the measurement results triggered by the event of the cell #1 in the CSI part 2 is Pp+Pq.

[0545] As shown in Table 8, taking the occurrence of event p and event q in K events associated with one cell (e.g., cell #1) of the terminal device as an example, the reporting parameters corresponding to event p include reporting parameter #a and reporting parameter #b, the number of reporting parameter #a and reporting parameter #b satisfying the condition of event p is x and y respectively, the reporting parameters corresponding to event q include reporting parameter #c and reporting parameter #d, the number of reporting parameter #c and reporting parameter #d satisfying the condition of event q is m and n respectively, the reporting parameter #a or reporting parameter #b or reporting parameter #c or reporting parameter #d can be any one of the foregoing reporting parameters #1-#11, x, y, m and n are positive integers, therefore one measurement report reported by the terminal device includes CSI part 1 and CSI part 2, wherein the CSI part 1 carries the index information of event p and event q, the reporting number x of reporting parameter #a and the reporting number y of reporting parameter #b corresponding to event p, and the reporting number m of reporting parameter #c and the reporting number n of reporting parameter #d corresponding to event q, the CSI part 2 carries the measurement results reported by event p and event q, i.e., the measurement quantities corresponding to x reporting parameter #a and y reporting parameter #b corresponding to event p, and the measurement quantities corresponding to m reporting parameter #c and n reporting parameter #d corresponding to event q. If the required payload sizes of reporting parameter #a, reporting parameter #b, reporting parameter #c and reporting parameter #d are Pa, Pb, Pc and Pd respectively, the payload size corresponding to CSI part 2 is the sum of the payload size corresponding to the measurement quantities of x reporting parameter #a, the payload size corresponding to the measurement quantities of y reporting parameter #b, the payload size corresponding to the measurement quantities of m reporting parameter #c and the payload size corresponding to the measurement quantities of n reporting parameter #d, i.e., the payload size corresponding to CSI part 2 is S=Pa*x+Pb*y+Pc*m+Pd*n.

[0546] Optionally, the foregoing measurement report contains only the measurement results of the event triggered reporting related to one cell.

[0547] Table 8

[0548] As shown in Table 9, the terminal reports the measurement results of events p and q related to K events associated with one cell of the terminal device through one measurement report, which is different from Table 8 in that only the index information of events p and q is included in the CSI part 1, and the reporting number of each reporting parameter corresponding to the events p and q does not need to be reported. For example, the reporting number of each reporting parameter corresponding to events p and q. Specifically, the one measurement report includes CSI part 1 and CSI part 2, wherein the index of events p and q is carried in the CSI part 1, and the related measurement results corresponding to events p and q are carried in the CSI part 2. The related measurement results corresponding to events p and q are Yp and Yq, respectively. The load size corresponding to Yp and Yq can be determined by the foregoing step 1, that is, the payload size corresponding to the CSI part 2 is S=Yp+Yq.

[0549] Table 9

[0550] Exemplarily, the terminal device indicates to the network device the load size required for reporting the measurement results related to events corresponding to one cell. For example, the load size required for reporting the measurement results related to each event in M events can be determined according to the load size required for reporting the measurement results related to events corresponding to the corresponding cell indicated by the terminal device to the network device.

[0551] Optionally, the load size required for the measurement results related to events corresponding to one cell can be carried in a first part CSI Part 1 of a measurement report, and the measurement results related to events corresponding to the cell are carried in a second part CSI Part 2 of the measurement report, and the load size is determined according to the load size of the measurement results related to events corresponding to the cell indicated in the first part CSI Part 1 of the measurement report.

[0552] Optionally, the load size required for the measurement results related to events corresponding to one cell can be carried in scheduling request signaling or reporting indication signaling, and the load size required for the measurement results related to events corresponding to the cell carried in the measurement report is determined according to the load size of the measurement results related to events corresponding to the cell indicated by the scheduling request signaling or the reporting indication signaling.

[0553] Step 3: Determine the load size of the measurement report, which includes at least one measurement result related to events corresponding to M1 cells.

[0554] Method one: report with fixed load size.

[0555] In one example, the terminal device determines the payload size of the measurement report as the payload size of the cell with the largest payload size of the measurement results associated with the cell among the M cells.

[0556] For example, the network device configures, and / or the terminal device determines, and / or the protocol specifies that the terminal device associates K CCs, e.g., CC#1, CC#2, …, CC#n, …, CC#K, and the K CCs are associated with event-triggered reporting, and the payload sizes of the measurement results associated with the events of the K CCs are Z1, Z2, …, Zn, …, ZK, respectively, which can be determined by the aforementioned step 2. Among the K CCs, if the payload size of the measurement results associated with the events of CC#n is the largest, i.e., Zn, then the terminal device determines the payload size of the measurement report as F = Zn.

[0557] Optionally, when there is an event in CC#1 among the K CCs, and the payload size a of the measurement results associated with the events of the CC#1 is smaller than F, then the remaining positions are filled with special values, e.g., all 0, and the corresponding payload size is F-a. The specific implementation of the event-triggered reporting of one CC can be referred to the related description of the aforementioned step 2.

[0558] Optionally, when there is an event in one or more CCs among the K CCs, and the payload size b of the measurement results associated with the events of the one or more CCs is smaller than F, then the remaining positions are filled with special values, e.g., all 0, and the corresponding payload size is F-b; when the payload size c of the measurement results associated with the events of the one or more CCs is larger than F, then the excess part can be discarded according to a predefined priority, e.g., the measurement results associated with the events of the scell or the neighboring cell can be discarded.

[0559] As shown in Table 10 below, it is assumed that the network device configures the terminal device with multiple cells, e.g., CC#1, CC#2, and CC#3 are associated with event-triggered reporting, and the payload sizes of the measurement results associated with the events of the three CCs are Z1, Z2, and Z3, respectively, which can be determined by the aforementioned step 2, and Z3 is the largest, then the terminal device determines the payload size of the measurement report to be reported as F = Z3.

[0560] Table 10

[0561] In another example, the terminal device determines the payload size of the measurement report as the sum of the payload sizes of the measurement results associated with each of the M cells.

[0562] That is, according to the manner of step 2 above, the terminal device can determine the load size required by the measurement result related to each of the M cells, and take the sum of the load sizes required by the measurement results related to all the cells as the load size of the measurement report.

[0563] For example, the network device configures, and / or the terminal device determines, and / or the protocol specifies that the terminal device is associated with K CCs, such as CC#1, CC#2, …, CC#n, …, CC#K, the K CCs are associated with event-triggered reporting, and the load sizes required by the measurement results related to the events of the K CCs are Z1, Z2, …, Zn, …, ZK respectively, which can be determined according to the aforementioned step 2. Then, the terminal device determines the payload size of the measurement report as: F = Z1 + Z2 + … + ZK.

[0564] Optionally, if events occur in all the M cells, the terminal device can report the measurement results related to each of the M cells in the order of reporting specified by the protocol (for example, the cell indexes are in ascending order or descending order, or other specified order), and the reporting order of the reporting parameters corresponding to each cell.

[0565] For example, when one or more of the K CCs have events, the load sizes required by the measurement results related to the events of the one or more CCs can be reported according to the aforementioned step 2; when one or more of the K CCs have no events, the reporting positions corresponding to the one or more CCs are filled with a predefined value, for example, 0, and the length of the predefined value is the load size required by the measurement result related to the event of the one or more CCs.

[0566] In yet another example, the terminal device determines the payload size of the measurement report as the payload size of the event with the largest load size required by the measurement result related to the event among the X events corresponding to the M cells.

[0567] For example, the network device configures, and / or the terminal device determines, and / or the protocol specifies that the terminal device is associated with K CCs, such as CC#1, CC#2, …, CC#K, the K CCs are associated with event-triggered reporting, wherein CC#1 supports event-triggered reporting of event 1 and event 2, CC#2 supports event-triggered reporting of event a and event b, …, and CC#K supports event-triggered reporting of event i and event ii. The load sizes required by the measurement results related to each event in each of the K CCs can be determined according to step 1, and if the largest load size required by the measurement result related to the event among all the events of the K CCs is Xi corresponding to event i of CC#K, the terminal device determines the payload size of the reported measurement report as: F = Xi.

[0568] Optionally, when there is one or more events of one CC, or there are one or more events of multiple CCs, the size of the load required for reporting the measurement results related to the one or more events of the one or more CCs is less than Xi, the remaining positions are filled with special values; when the size of the load required for reporting the measurement results related to the one or more events of the one or more CCs is greater than Xi, the excess part is discarded according to a predefined priority.

[0569] For example, if only one event of one CC occurs, for example, event 1 of CC#1 occurs, the size of the load required for event 1 on the CC#1 corresponding to X1 is less than Xi, the remaining space is filled with special values, for example, all 0, and the corresponding size of the load is Xi-X1. If there are event 1 and event 2 of CC#1 and event b of CC#2, the size of the load required for the measurement results related to event 1, event 2 and event b is X1+X2+Xa, which is greater than Xi, the excess part is discarded according to a predefined priority, for example, the reporting priority of CC#1 is higher than that of CC#2, X1+X2 is less than Xi, and the terminal device can report the measurement results related to event 1 and event 2 of CC#1, and discard the measurement results related to event b of CC#2.

[0570] Method two: reporting with flexible load size.

[0571] Exemplarily, the terminal device can send first information to the network device, the first information being used to indicate information of each of M1 cells, and / or a size of a load of a measurement report, and / or information of an event occurring in each of the M1 cells or event information required for reporting related measurement results of each of the M1 cells, and / or a reporting number of each reporting parameter corresponding to each event occurring in each of the M1 cells or a reporting number of each reporting parameter corresponding to each event required for reporting related measurement results of each of the M1 cells, and / or a size of a load required for each of the M1 cells, and / or a size of a load required for each event corresponding to each of the M1 cells.

[0572] Optionally, the sending order of the first information and the measurement report is not limited in the present application, which can be sending the first information first and then sending the measurement report, or sending the measurement report first and then sending the first information, or sending the first information and the measurement report at the same time.

[0573] Optionally, the sending order of the first information and the second information is not limited in the present application, which can be sending the first information first and then sending the second information, or sending the second information first and then sending the first information, or sending the first information and the second information at the same time.

[0574] Optionally, the first information can be carried in a CSI part 1 of the measurement report, or in scheduling request signaling, or in reporting indication signaling, and of course can be other signaling, which is not limited in the present application.

[0575] Next, the specific content contained in the first information is exemplarily illustrated.

[0576] The first possible way is that the first information includes M1 cell information.

[0577] Exemplarily, the network device configures K CCs for the terminal device, for example, CC#1, CC#2, …, CC#K, and associates event-triggered reporting, when M1 cells have event occurrence, the terminal device can send the information of the M1 cells to the network device, for example, cell index, or the state of whether each of the K configured cells has event occurrence. The load size of the measurement report is the sum of the load sizes required by the measurement results related to the M1 cell event triggers corresponding to the M1 cell information. The load size required by the measurement result related to each of the M1 cell event triggers can be determined according to the foregoing step 2. For example, when the terminal device has event occurrence in CC#1 and CC#2, the terminal device can report the cell information (for example, cell index, or bitmap form indicating that CC#1 and CC#2 have event occurrence) of CC#1 and CC#2, and if the payload sizes required by the measurement results related to the CC#1 and CC#2 event triggers are Z1 and Z2 respectively, then the load size of the measurement report reported by the terminal device is: F = Z1 + Z2. In the present application, the load size required by the cell can be understood as the load size required by the measurement result related to the event trigger of the reported cell (or CC).

[0578] Optionally, if the first information is carried in the CSI part 1 of the measurement report, the payload size of the measurement report reported by the terminal device is the sum of the payload sizes required by the M1 cells corresponding to the information of the M1 cells sent by the terminal device to the network device plus the number of bits required for reporting the information of the M1 cells. Wherein, the payload size of the CSI part 1 of the measurement report is the number of bits required for reporting the information of the M1 cells, and the payload size of the CSI part 2 of the measurement report is the sum of the payload sizes required by the event-triggered measurement results of the M1 cells corresponding to the information of the M1 cells sent by the terminal device to the network device. For example, when the CC#1 and CC#2 of the terminal device have events, the terminal device can report the cell information (such as cell index, or bitmap form indicating that CC#1 and CC#2 have events) of CC#1 and CC#2 through a CSI Part 1 of a measurement report, if the payload sizes required by the measurement results related to CC#1 and CC#2 are Z1 and Z2 respectively, then the payload size corresponding to the CSI Part 2 of the measurement report reported by the terminal device is Z1+Z2, the payload size corresponding to the CSI Part 1 of the measurement report reported by the terminal device is L, L is the number of bits required for reporting the cell information of the event, therefore, the payload size of the measurement report reported by the terminal device is F=Z1+Z2+L.

[0579] The second possible way is that the first information includes M1 cell information and the information of the event occurred in each of the M1 cells.

[0580] Exemplarily, the network device configures K CCs, for example, CC#1, CC#2, …, CC#K, for the terminal device to report event trigger, when M1 cells exist event, for example, cell 1 to cell M1, event 1 occurs on cell 1, event 1 and event 2 occur on cell 2, …, event m1 occurs on cell M1, event 1, event 2, …, or event m1 in the example of the present application is any one of event #A to event #K, the terminal device can send M1 cell information, for example, cell index or whether each cell of all configured K cells exists event, and event information of each cell of M1 cells, for example, event index, to the network device. The load size of the measurement report is the sum of the load size required by the measurement result related to M1 cell event trigger corresponding to M1 cell information, the load size required by the measurement result related to each cell event trigger in M1 cells can be determined according to the foregoing step 2, and the load size required by the measurement result related to the event occurring on each cell in M1 cells can be determined according to the foregoing step 1. For example, when CC#1 and CC#2 of the terminal device exist event, event 1 occurs on CC#1, and event 2 occurs on CC#2, the terminal device can report cell information (for example, cell index, or bitmap form indicates that CC#1 and CC#2 exist event) of CC#1 and CC#2, and event information (for example, event index) of event 1 occurring on CC#1 and event 2 occurring on CC#2, if the payload size of the measurement result related to CC#1 and CC#2 event trigger is Z1 and Z2 respectively, then the load size of the measurement report reported by the terminal device is payload size: F = Z1 + Z2.

[0581] Optionally, if the first information is carried in the CSI part 1 of the measurement report, the payload size of the measurement report reported by the terminal device is the sum of the payload sizes required by the information of the M1 cells sent by the terminal device to the network device, plus the number of bits required for reporting the information of the M1 cells, plus the number of bits required for reporting the information of the events occurred in each of the M1 cells. Wherein the payload size of the CSI part 1 of the measurement report is the sum of the number of bits required for reporting the information of the M1 cells and the number of bits required for reporting the information of the events occurred in each of the M1 cells, and the payload size of the CSI part 2 of the measurement report is the sum of the payload sizes required by the measurement results of the event triggering related to the M1 cells sent by the terminal device to the network device. For example, when the CC#1 and CC#2 of the terminal device have events, event 1 occurs in CC#1 and event 2 occurs in CC#2, the terminal device can report the cell information (such as cell index, or bitmap form indicating that CC#1 and CC#2 have events) of CC#1 and CC#2 and the information of the events (such as event index) occurred in CC#1 and CC#2 through the CSI Part 1 of one measurement report, if the payload sizes required by the measurement results related to CC#1 and CC#2 are Z1 and Z2 respectively, then the payload size corresponding to the CSI Part 2 of the measurement report reported by the terminal device is Z1+Z2, the payload size corresponding to the CSI Part 1 of the measurement report reported by the terminal device is L1+L2, L1 is the number of bits required for reporting the information of the cells having events, and L2 is the number of bits required for reporting the information of the events, therefore the payload size of the measurement report reported by the terminal device is F=Z1+Z2+L1+L2.

[0582] The third possible way is that the first information includes M1 cell information, information of events occurred in each of the M1 cells, and the number of reports corresponding to each reporting parameter corresponding to each event occurred in each of the M1 cells.

[0583] Exemplarily, the network device configures K CCs, e.g., CC#1, CC#2, …, CC#K, for the terminal device to report event trigger, when M1 cells exist event, e.g., cell 1 to cell M1, event 1 occurs on cell 1, event 1 and event 2 occur on cell 2, …, event m1 occurs on cell M1, event 1, event 2, …, or event m1 in the example of the present application is any one of event #A to event #K, the terminal device can send M1 cell information, e.g., cell index or state of whether event occurs in each of all configured K cells, event information of each of M1 cells, e.g., event index, and reporting number of each reporting parameter corresponding to each event occurring on each of M1 cells, to the network device. The load size of the measurement report is the sum of the load size required by the measurement result related to the event trigger of M1 cells corresponding to the information of M1 cells, the load size required by the measurement result related to the event trigger of each of M1 cells can be determined according to the foregoing step 2, and the load size required by the measurement result related to the event occurring on each of M1 cells can be determined according to the foregoing step 1. For example, when CC#1 and CC#2 of the terminal device exist event, event 1 occurs on CC#1, event 2 occurs on CC#2, the reporting parameter corresponding to event 1 includes reporting parameter #a and reporting parameter #b, the number of reporting parameter #a and reporting parameter #b satisfying the condition of event 1 is x and y respectively, the reporting parameter corresponding to event 2 includes reporting parameter #c and reporting parameter #d, the number of reporting parameter #c and reporting parameter #d satisfying the condition of event 2 is m and n respectively, reporting parameter #a or reporting parameter #b or reporting parameter #c or reporting parameter #d can be any one of the foregoing reporting parameter #1 to reporting parameter #11, then the terminal device can report cell information (e.g., cell index, or bitmap form indicating that CC#1 and CC#2 exist event) of CC#1 and CC#2, event information (e.g., event index) of event 1 occurring on CC#1 and event 2 occurring on CC#2, and reporting number x of reporting parameter #a corresponding to event 1, reporting number y of reporting parameter #b corresponding to event 1, reporting number m of reporting parameter #c corresponding to event 2, and reporting number m of reporting parameter #d corresponding to event 2. If the payload size of the measurement result related to the event trigger of CC#1 and CC#2 is Z1 and Z2 respectively, then the load size of the measurement report reported by the terminal device is: F = Z1 + Z2.

[0584] Optionally, if the first information is carried in the CSI part 1 of the measurement report, the payload size of the measurement report reported by the terminal device is: the sum of the payload sizes required by the information corresponding to the M1 cells sent by the terminal device to the network device, plus the number of bits required by the information of the aforementioned events occurred in each of the M1 cells, plus the sum of the number of bits required by the number x of the reported parameter #a corresponding to the event 1, the number y of the reported parameter #b corresponding to the event 1, the number m of the reported parameter #c corresponding to the event 2, and the number n of the reported parameter #d corresponding to the event 2. Wherein the payload size of the CSI part 1 of the measurement report is the sum of the number of bits required by the information of the M1 cells, the number of bits required by the information of the events occurred in each of the M1 cells, and the number of bits required by the number x of the reported parameter #a corresponding to the event 1, the number y of the reported parameter #b corresponding to the event 1, the number m of the reported parameter #c corresponding to the event 2, and the number n of the reported parameter #d. The payload size of the CSI part 2 of the measurement report is the sum of the payload sizes required by the measurement results of the event-triggered related measurements corresponding to the M1 cells sent by the terminal device to the network device.For example, when there are events in CC#1 and CC#2 of the terminal device, event 1 occurs in CC#1, event 2 occurs in CC#2, the number of reported parameters #a corresponding to event 1 is x, the number of reported parameters #b corresponding to event 1 is y, the number of reported parameters #c corresponding to event 2 is m, and the number of reported parameters #d corresponding to event 2 is m, the terminal device can report the cell information (for example, cell index, or bitmap form indicating that CC#1 and CC#2 have events) of CC#1 and CC#2, the information of the events (for example, event index) occurring in CC#1 and CC#2, and the number of reported parameters #a corresponding to event 1, the number of reported parameters #b corresponding to event 1, the number of reported parameters #c corresponding to event 2, and the number of reported parameters #d corresponding to event 2 in the CSI Part 1 of the measurement report. If the payload size required by the measurement results related to CC#1 and CC#2 is Z1 and Z2 respectively, the payload size corresponding to the CSI Part 2 of the measurement report reported by the terminal device is Z1+Z2, and the payload size corresponding to the CSI Part 1 of the measurement report reported by the terminal device is Z3+Z4+Z5. Z3 is the number of bits required to report the cell information of the occurring events, Z4 is the number of bits required to report the information of the occurring events, and Z5 is the number of bits required to report the number of reported parameters corresponding to the occurring events. Therefore, the payload size of the measurement report reported by the terminal device is F=Z1+Z2+Z3+Z4+Z5.

[0585] In the fourth possible manner, the first information includes M1 cell information and / or the payload size required by each of the M1 cells.

[0586] For example, the network device configures K CCs, such as CC#1, CC#2, …, and CC#K, for the terminal device to report the events triggered by the association. When there are events in M1 cells, the terminal device can send the information of the M1 cells, such as cell index or the state of whether there are events in each of the K cells configured by the terminal device, and / or the payload size required by each of the M1 cells to the network device. The payload size of the measurement report is the sum of the payload sizes required by each of the M1 cells reported by the terminal device.

[0587] Optionally, if the first information is carried in the CSI part 1 of the measurement report, the payload size of the measurement report reported by the terminal device is the sum of the payload sizes required by the M1 cells corresponding to the information of the M1 cells sent by the terminal device to the network device, plus the number of bits required to send the first information.

[0588] In a fifth possible manner, the first information includes M1 cell information and / or a required payload size of each occurred event corresponding to each of the M1 cells.

[0589] For example, the network device configures K CCs, such as CC#1, CC#2, …, CC#K, for the terminal device to report an event trigger, when M1 cells have events occurred, the terminal device can send information of the M1 cells, such as cell indexes or a state of whether each of the K configured cells has an event occurred, and / or a required payload size of each occurred event corresponding to each of the M1 cells, to the network device. The payload size of the measurement report is the sum of the required payload sizes of each occurred event corresponding to each of the M1 cells reported by the terminal device.

[0590] Optionally, if the first information is carried in the CSI part 1 of the measurement report, the payload size of the measurement report reported by the terminal device is the sum of the required payload sizes of the M1 cells corresponding to the information of the M1 cells sent by the terminal device to the network device, plus the number of bits for sending the first information.

[0591] It can be understood that the above implementation manners are only examples given for the convenience of understanding, and other schemes are not excluded.

[0592] Optionally, the terminal device can also report a required payload size of the measurement result related to the cell having the event occurred. For example, the terminal device can report the required payload size in a scheduling request, or an indication resource, or the CSI part 1 of the measurement report; or, the network configures one or more payload sizes, and the terminal device indicates one of the payload sizes according to the required payload size of the measurement result related to the cell having the event occurred.

[0593] Optionally, each of the M cells can correspond to the same reporting resource, or each of the M cells can also correspond to different reporting resources, for example, the M cells correspond to the M reporting resources one by one; or, at least two of the M cells correspond to different reporting resources, for example, the M cells correspond to N reporting resources, and M

[0594] FIG. 7 shows a diagram of measurement results satisfying event reporting carried by one measurement report associated with multiple CCs. Assuming that one event, e.g., event 1, occurs on one cell, e.g., CC1, one measurement report reported by the terminal device can be one of the following three examples, as shown in (a) of FIG. 7, the CSI Part 1 of the measurement report includes the CC index (e.g., CC1), and the CSI Part 2 includes the event 1 predefined value, beam index #1, predefined value, beam quality #1, and predefined value; as shown in (b) of FIG. 7, the CSI Part 1 of the measurement report includes the CC index (e.g., CC1) and event index information (e.g., event #1), and the CSI Part 2 includes beam index #1, predefined value, beam quality #1, and predefined value; as shown in (c) of FIG. 7, the CSI Part 1 of the measurement report includes the CC index (e.g., CC1), event index information (e.g., event #1), and the number of reported beams, and the CSI Part 2 includes beam index #1 and beam quality #1. The above is only for the convenience of understanding, and the fields included in the first part and the second part of one measurement report are exemplarily described, without excluding other schemes.

[0595] That is, if the network device configures one measurement report configuration, it means that the measurement results of at least one event corresponding to M1 cells are carried in one measurement report, at this time, the first part of the one measurement report can be placed in front, and the second part is located behind the first part. The first part of the measurement results related to at least one event corresponding to M1 cells is carried in the first part of the one measurement report, and the second part of the measurement results related to at least one event corresponding to M1 cells is carried in the second part of the one measurement report. The first part and the second part can be independently encoded.

[0596] Case two: one measurement report configuration is associated with only one cell, that is, the terminal device reports the measurement results of at least one event corresponding to one of M1 cells through one measurement report.

[0597] Step 1: determine the load size required for reporting the measurement results related to one of X events, the specific implementation manner can refer to the related description of step 1 in case one described above, and for the sake of brevity, will not be repeated here.

[0598] Optionally, one measurement report includes a first part CSI Part 1 and a second part CSI Part 2, M cells correspond to multiple measurement report configurations, and the terminal device sends multiple measurement reports according to the priority ordering information of the multiple measurement report configurations. The first part of the multiple measurement reports includes the first part related to at least one event corresponding to M1 cells, and the second part of the multiple measurement reports includes the second part of the measurement results related to at least one event corresponding to M1 cells.

[0599] Step 2: Determine the load size of the event triggered reporting corresponding to one of the M cells (or one CC). The specific implementation can refer to the related description of step 2 or step 3 (M1 = 1) in the above case one. For brevity, the details are not repeated here. The load size of each subsequent measurement report can be determined according to the load size required for reporting the measurement results related to the cell in step 2 of the above case one.

[0600] Step 3: Determine the load size of multiple measurement reports, each of which includes measurement results related to an event corresponding to one of the M1 cells. That is, one measurement report corresponds to one cell, and one measurement report is used to carry the measurement results related to the event corresponding to the one cell.

[0601] (1) The measurement reports associated with different CCs are reported in a pre-defined priority order.

[0602] As an example, if the multiple measurement report configurations corresponding to one or more CCs are associated with the same scheduling request or indication resource, and the scheduling request or indication resource does not carry the cell information of the event occurrence and / or the measurement report configuration index, if there is no event occurrence in the event associated with a certain measurement report, the reporting position of the measurement report is filled with a pre-defined value, such as 0, and the length of the pre-defined value is the load size required for the measurement report. The load size required for the measurement report can be determined according to the above case one M1 = 1.

[0603] The network device configures the terminal device to report the event triggered reporting associated with K cells through the same reporting resource, and the load size of the measurement report is the sum of the load sizes of the measurement reports associated with the K cells. When there is no event occurrence in the measurement report corresponding to a certain CC, the reporting space corresponding to the CC can be filled with a special value. Alternatively, one or more measurement reports are reported through the same reporting resource, and one measurement report is associated with one cell. The load size required for reporting the one or more measurement reports is the sum of the load sizes of the one or more measurement reports, or the sum of the load sizes required for the event triggered reporting associated with all cells associated with the one or more measurement reports.

[0604] As shown in Table 11, for example, CC#1, CC#2 and CC#3 are associated with event triggered reporting, and the three CCs correspond to three measurement reports, for example, measurement report #1, measurement report #2 and measurement report #3, wherein the measurement report priority of CC#1 is higher than that of CC#2, and the priority of CC#2 is higher than that of CC#3. The terminal device reports the measurement reports #1, #2 and #3 corresponding to CC#1, CC#2 and CC#3 in turn according to the reporting priority order of the CCs. For example, when there is no event occurrence for CC#2, the measurement report #2 corresponding to CC#2 is filled with a pre-defined value, for example, 0.

[0605] Table 11

[0606] As another example, if the multiple measurement report configurations corresponding to the multiple CCs are associated with different scheduling requests or indication resources, or the multiple measurement report configurations corresponding to the multiple CCs are associated with the same scheduling request or indication resource, but the scheduling request or indication resource carries the cell information of the event occurrence or the cell information of the measurement result that needs to be reported, the measurement reports corresponding to the different CCs are reported according to the pre-defined priority order.

[0607] The network device configures the terminal device to report the event triggered reporting of K cells through the same reporting resource, and the load size of the measurement report is the sum of the load sizes required by all the CCs with event occurrence or the measurement results that need to be reported. Alternatively, one or more measurement reports are reported through the same reporting resource, and the load size required for reporting the one or more measurement reports is the sum of the load sizes of the measurement reports with event occurrence in the one or more measurement reports.

[0608] As shown in Table 12, the multiple cells of the terminal device, for example, CC#1, CC#2 and CC#3 are associated with event triggered reporting, and the three CCs correspond to three measurement reports, for example, measurement report #1, measurement report #2 and measurement report #3, wherein the measurement report priority of CC#1 is higher than that of CC#2, and the priority of CC#2 is higher than that of CC#3. The terminal device can report the measurement reports #1, #2 and #3 corresponding to CC#1, CC#2 and CC#3 in turn according to the reporting priority order of the CCs. For example, when there is no event occurrence for CC#2, the measurement report #2 corresponding to CC#2 does not need to be reported, that is, the terminal device can report the measurement reports #1 and #3 corresponding to CC#1 and CC#3 in turn according to the priority order.

[0609] Table 12

[0610] (2) One measurement report contains first part CSI part 1 and second part CSI part 2, the reporting size of CSI Part 2 is determined according to CSI Part 1. CSI Part 1 of different measurement reports is encoded according to priority, and CSI Part 2 of different measurement reports is encoded according to priority. CSI Part 1 and CSI Part 2 can be independently encoded. Each measurement report is associated with one CC.

[0611] As an example, if one or more CCs correspond to multiple measurement report configurations associated with the same scheduling request or indication resource, and the scheduling request or indication resource does not carry cell information of event occurrence, if there is no event occurrence in the event associated with a certain measurement report, the reporting position of CSI part 1 corresponding to the measurement report is filled with a pre-defined value, and at this time the measurement report has no CSI Part 2.

[0612] Optionally, CSI Part 1 of each measurement report can include one or more of the following: whether there is event occurrence of the measurement report; information of the event occurrence (such as event index, etc.); and reporting number of reporting parameters corresponding to each event. Optionally, the measurement result contained in CSI Part 2 of each measurement report is determined according to the information of CSI Part 1.

[0613] As shown in Table 13, the priority of one measurement report corresponding to CC#1 is higher than that of one measurement report corresponding to CC#2, and the priority of one measurement report corresponding to CC#2 is higher than that of one measurement report corresponding to CC#3, so the terminal device can report measurement report #1, measurement report #2 and measurement report #3 corresponding to CC#1, CC#2 and CC#3 in turn according to the reporting priority order of the CCs. For example, when there is no event occurrence of CC#2, a pre-defined value, for example 0, is filled in CSI part 1 of measurement report #2 corresponding to CC#2. Correspondingly, CSI part 2 of measurement report #2 corresponding to CC#2 is determined according to CSI part 1 of measurement report #2 corresponding to CC#2, and does not exist.

[0614] Table 13 CSI Part 1 mapping order of measurement reports of multiple CCs

[0615] Part 2 mapping order of measurement reports of multiple CCs

[0616] As another example, if the multiple measurement report configurations corresponding to the multiple CCs are associated with different scheduling request or indication resources, or the multiple measurement report configurations corresponding to the multiple CCs are associated with the same scheduling request or indication resource, but the scheduling request or indication resource carries the cell information of the event occurrence and / or the measurement report configuration index, if there is no event occurrence in the event associated with a measurement report, the CSI Part1 and the CSI Part2 of the measurement report corresponding to the measurement result of the event occurrence or the event triggering need to be reported according to the pre-defined priority order.

[0617] As shown in Table 14, the priority of the measurement report corresponding to CC#1 is higher than that of the measurement report corresponding to CC#2, and the priority of the measurement report corresponding to CC#2 is higher than that of the measurement report corresponding to CC#3, and then the terminal device can report the measurement report #1, the measurement report #2 and the measurement report #3 corresponding to CC#1, CC#2 and CC#3 in turn according to the reporting priority order of the CCs. For example, when there is no event occurrence of CC#2, the CSI Part1 and the CSI Part2 of the measurement report #2 corresponding to CC#2 do not need to be reported, that is, the terminal device can report the CSI Part1 of the measurement report #1 and the measurement report #3 corresponding to CC#1 and CC#3, and the CSI Part2 of the measurement report #1 and the measurement report #3 in turn according to the priority order.

[0618] Table 14: Part 1 mapping order of measurement reports of multiple CCs

[0619] Part 2 mapping order of measurement reports of multiple CCs

[0620] Optionally, each of the M cells can correspond to the same reporting resource, or each of the M cells can also correspond to different reporting resources, for example, one-to-one correspondence between the M cells and the M reporting resources, or at least two of the M cells correspond to different reporting resources, for example, correspondence between the M cells and the N reporting resources, M

[0621] Based on the above scheme, the terminal device can perform cross-cell event triggering reporting, so as to avoid the terminal device reporting invalid measurement reports to the network device. In addition, the terminal device can define the reporting format of the measurement report carrying the measurement result related to one or more events occurring, so as to avoid the resource waste caused by allocating the corresponding reporting resource for each event when the terminal device supports or configures one or more events occurring on multiple cells, and improve the transmission performance.
