[0001] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of China on October 31, 2023, with application number 202311442792.3 and application name “Communication Method and Communication Device”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The embodiments of the present application relate to the field of communications, and more specifically, to a communication method and a communication device. Background Art

[0003] In mobile communication systems, terminal devices can report reference signal measurement results for the current serving cell and neighboring cells to network equipment. These measurement results are crucial for network equipment to manage these devices. For example, if the measurement results indicate that the channel quality of the current serving cell is good, the network equipment can schedule more data packets and update its scheduling strategy. If the measurement results indicate that the channel quality of a neighboring cell is better than that of the current serving cell, the network equipment can instruct the terminal device to perform mobility management processes such as cell handover and beam switching.

[0004] However, when the terminal device reports the measurement results, it will also occupy uplink transmission resources. How to efficiently report the measurement is worth studying.

[0005] Summary of the Invention

[0006] The present application provides a communication method and a communication device, which can quickly and timely report measurement results while reducing the uplink resource occupation of terminal equipment.

[0007] In a first aspect, a communication method is provided, which is executed by a terminal device. The terminal device here can refer to the terminal device itself or a processor, module, chip, or chip system that implements the method in the terminal device. The method includes: receiving measurement configuration information from a network device, the measurement configuration information including an event trigger condition; the physical PHY layer measures the reference signal to be measured, determines that the event trigger condition is met, and sends first indication information to the medium access control MAC layer; the MAC layer sends the measurement result to the network device through MAC layer signaling based on the first indication information.

[0008] In this implementation, the PHY layer of the terminal device can measure the reference signal to be measured. If it is determined that the measurement result obtained by the measurement meets the event triggering condition, the PHY layer can send a first indication information to the MAC layer. The MAC layer can send the measurement result through MAC layer signaling (such as MAC CE) based on the first indication information, so that the network device can receive the measurement result and can update the scheduling strategy or perform mobility management such as cell switching and beam switching based on the measurement result. The present application determines the event triggering through the PHY layer and sends the measurement result through MAC layer signaling. When the event is triggered and there are uplink resources, the terminal device can quickly and promptly report the measurement result. In addition, it can also reduce the uplink resource occupancy of the terminal device.

[0009] In combination with the first aspect, in certain implementations of the first aspect, the MAC layer sends the measurement result to the network device through MAC layer signaling based on the first indication information, including: the MAC layer receives the first indication information, triggering the MAC layer to report; and sending the measurement result to the network device through the MAC layer signaling.

[0010] In this implementation, the PHY layer of the terminal device can measure the reference signal to be measured. If it determines that the measurement result meets the event trigger condition, the PHY layer can send first indication information to the MAC layer, thereby triggering the MAC layer to report. The terminal device can then send the measurement result via MAC layer signaling. In other words, the MAC layer can enter a report trigger state. When the MAC layer is in the report trigger state, the measurement result can be sent via MAC layer signaling.

[0011] In combination with the first aspect, in certain implementations of the first aspect, the MAC layer sends the measurement results to the network device through MAC layer signaling based on the first indication information, including: when the MAC layer receives the first indication information, starting a periodic reporting timer; when the periodic reporting timer times out, triggering the MAC layer to report and restarting the periodic reporting timer, and sending the measurement results through the MAC layer signaling.

[0012] In this implementation, if the PHY layer determines that the measurement results of the reference signal to be measured consistently meet the event triggering condition, the PHY layer does not need to send the first indication information to the MAC layer multiple times. Instead, the MAC layer can start a periodic reporting timer after receiving the first indication information for the first time. When the periodic reporting timer expires, the MAC layer can still trigger a MAC layer report and restart the periodic reporting timer to send the measurement results via MAC layer signaling. This avoids repeated transmission of the first indication information and reduces the complexity of inter-layer interaction.

[0013] In combination with the first aspect, in some implementations of the first aspect, the method further includes: after sending the measurement result to the network device through the MAC layer signaling, canceling the MAC layer reporting trigger.

[0014] In this implementation, if the MAC layer reports the measurement result via MAC layer signaling, the MAC layer report trigger can be canceled, that is, the MAC layer report trigger state can be canceled to avoid being in the triggered state and continuously using uplink resources for reporting. If the MAC layer still needs to report the measurement result, it needs to receive the first indication information again or the periodic reporting timer will expire.

[0015] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: when the MAC layer receives the first indication information, starting a periodic reporting timer; when the PHY layer determines that the event triggering condition is not met, sending a second indication information to the MAC layer; and the MAC layer stopping the periodic reporting timer based on the second indication information.

[0016] In this implementation, if the MAC layer receives the first indication information sent by the PHY layer, it can start the periodic reporting timer; if the PHY layer determines that the measurement result of the reference signal to be measured does not meet the event triggering condition, the PHY layer can send a second indication information to the MAC layer, and the MAC layer can stop the periodic reporting timer based on the second indication information, so that the MAC layer no longer needs to send the measurement result to the network device.

[0017] With reference to the first aspect, in certain implementations of the first aspect, the MAC layer signaling includes a MAC CE. Optionally, the MAC layer signaling may also include other control signaling, for example, MAC layer control signaling that may appear in future network systems.

[0018] In combination with the first aspect, in certain implementations of the first aspect, the MAC CE includes at least one of the following: an identifier of a reference signal set, an identifier of a serving cell, an identifier of a candidate cell, an identifier of a secondary cell, an identifier of a reference signal, a quantity to be measured, and a measurement result corresponding to the quantity to be measured.

[0019] In combination with the first aspect, in certain implementations of the first aspect, the physical PHY layer measures the reference signal to be measured, determines that the event trigger condition is met, and sends first indication information to the media access control MAC layer, including: the PHY layer measures the first reference signal and the second reference signal, determines that both the first reference signal and the second reference signal meet the event trigger condition, and sends the first indication information to the MAC layer; the MAC layer sends the measurement result to the network device through MAC layer signaling based on the first indication information, including: the MAC layer sends the measurement result corresponding to the first reference signal to the network device through MAC layer signaling based on the first indication information and preset rules.

[0020] In this implementation, if uplink resources are insufficient, the measurement results corresponding to the first reference signal and the measurement results corresponding to the second reference signal cannot be sent simultaneously via MAC layer signaling. In this case, the MAC layer can filter based on preset rules and select the measurement results corresponding to the first reference signal that meet the preset rules, so that the MAC layer signaling prioritizes the measurement results corresponding to the first reference signal. This facilitates timely reporting of the more important measurement results.

[0021] In combination with the first aspect, in certain implementations of the first aspect, the measurement configuration information also includes the preset rules, and the preset rules include at least one of the following: selecting the measurement result of the candidate cell based on signal strength; selecting the measurement result of the reference signal set based on signal strength; selecting the measurement result of the reference signal based on signal strength; selecting the measurement result based on the measurement result of the special cell; selecting the measurement result based on the measurement result of the reference signal received power RSRP.

[0022] It should be noted that in addition to the above preset rules, other preset rules may also be included. For example, the network device may be configured with different priorities for candidate cells / reference signal sets / reference signals. When the terminal device needs to perform MAC CE truncation, it selects the measurement result group corresponding to the candidate cell / reference signal set / reference signal with the highest priority and includes it in the MAC CE.

[0023] In addition, the above preset rules may be used simultaneously or partially. Optionally, the network device may specify the preset rules to be used in the measurement configuration information, or the preset rules to be used may be predefined in the protocol.

[0024] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: when there are no available uplink resources to send the MAC layer signaling, sending a scheduling request SR information to the network device, wherein the scheduling request information is used to request uplink resources for sending the measurement results.

[0025] In this implementation, if the terminal device has no uplink resources to send MAC layer signaling, it can send a scheduling request to the network device, requesting the network device to allocate uplink resources for uplink transmission of measurement results. Specifically, when there are no available uplink resources to send MAC layer signaling (such as MAC CE), the MAC layer of the terminal device triggers an SR and can instruct the PHY layer to send a PUCCH SR.

[0026] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: receiving a first scheduling request configuration and a second scheduling request configuration from the network device; when the data volume of the measurement result is greater than or equal to a first preset value, selecting the first scheduling request configuration to send the scheduling request information; when the data volume of the measurement result is less than the first preset value, selecting the second scheduling request configuration to send the scheduling request information.

[0027] In this implementation, the terminal device can select an appropriate scheduling request configuration based on the data volume of the measurement results, so as to fully utilize the uplink resources allocated by the network device, avoid the situation where there are too few uplink resources to send MAC CE, and avoid the problem of excessive waste of uplink resources.

[0028] In combination with the first aspect, in certain implementations of the first aspect, the event trigger conditions include cell-level event trigger conditions, beam-level event trigger conditions, and reference signal set-level event trigger conditions, and the measurement results include cell-level measurement results, beam-level measurement results, and reference signal set-level measurement results.

[0029] Among them, the cell-level event triggering conditions may include any of the following: the measurement result of the serving cell is higher than the preset threshold; the measurement result of the serving cell is lower than the preset threshold; the measurement result of the neighboring area is higher than the measurement result of the serving cell / special cell. The preset threshold; the measurement result of the neighboring area is higher than the preset threshold; the measurement result of the serving cell is lower than the first threshold, and the measurement result of the neighboring area is higher than the threshold; the measurement result of the neighboring area is higher than the measurement result of the secondary cell by a preset threshold.

[0030] The event trigger conditions at the beam level may include any of the following: the measurement result of the beam being used by the serving cell is higher than the preset threshold; the measurement result of the beam being used by the serving cell is lower than the preset threshold; the measurement result of a beam in the neighboring cell is higher than the preset threshold; the measurement result of a beam in the neighboring cell is higher than the preset threshold; the measurement result of a beam in the neighboring cell is higher than the preset threshold; the measurement result of the beam being used by the serving cell is lower than the third threshold, and the measurement result of a beam in the neighboring cell is higher than the fourth threshold; the measurement result of a beam in the neighboring cell is higher than the preset threshold.

[0031] The event triggering conditions at the reference signal set level may include any one of the following: the measurement result of the reference signal set corresponding to the serving cell is higher than the preset threshold; the measurement result of the reference signal set corresponding to the serving cell is lower than the preset threshold; the measurement result of the reference signal set corresponding to the neighboring cell is higher than the preset threshold than the measurement result of the reference signal set corresponding to the serving cell / special cell; the measurement result of the reference signal set corresponding to the neighboring cell is higher than the preset threshold; the measurement result of the reference signal set corresponding to the serving cell is lower than the fifth threshold, and the measurement result of the reference signal set corresponding to the neighboring cell is higher than the sixth threshold; the measurement result of the reference signal set corresponding to the neighboring cell is higher than the preset threshold than the measurement result of the reference signal set corresponding to the secondary cell.

[0032] It should be noted that, in the implementation of the first aspect, the reference signal is measured through the PHY layer and it is determined whether the event trigger condition is met. If the event trigger condition is met, the measurement result can be sent to the MAC layer and instructed to report to the MAC layer. In some other implementations other than the implementation of the first aspect, the reference signal can also be measured through the PHY layer, and the event trigger condition can be determined through the MAC layer. If the event trigger condition is met, the report is made. Alternatively, the reference signal can also be measured through the MAC layer, and it can be determined whether the event trigger condition is met. If the event trigger condition is met, the report is made through the MAC layer. Alternatively, the reference signal can also be measured through the PHY layer, and it can be determined whether the event trigger condition is met. If the event trigger condition is met, the report is made through the PHY layer. Specifically:

[0033] In some possible implementations, the communication method may include: a terminal device receiving measurement configuration information sent by a network device, the measurement configuration information including an event triggering condition; a PHY layer of the terminal device measuring a reference signal to be measured and sending a measurement result to a MAC layer; the MAC layer determining whether the measurement result of the reference signal to be measured meets the event triggering condition, i.e., the MAC layer determining whether an event is met / triggered.

[0091] In the embodiment of the present application, the network device can be any device with wireless transceiver function. The device includes, but is not limited to, an evolved Node B (eNB), a radio network controller (RNC), a Node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., a home evolved NodeB, or a home Node B, HNB), a baseband unit (BBU), an access point (AP) in a wireless fidelity (WIFI) system, a wireless relay node, a wireless backhaul node, etc., and may also be a 5G, such as a next-generation NodeB (gNB) in an NR system, or one or a group of antenna panels (including multiple antenna panels) of a base station in a 5G system, or a network node constituting a gNB, such as a baseband unit (BBU), a distributed unit (DU), a centralized unit (CU), etc., or a base station in a next-generation (e.g., sixth-generation (6G)) communication system, etc.

[0092] In some deployments, a gNB may include both a CU and a DU. For example, the CU implements some gNB functions, while the DU implements some gNB functions. For example, the CU is responsible for processing non-real-time protocols and services and implementing the functions of the radio resource control (RRC) and packet data convergence protocol (PDCP) layers. The DU may include the functions of the radio link control (RLC) and medium access control (MAC) layers, as well as some functions of the physical (PHY) layer.

[0093] Network equipment provides services for cells, and terminal devices communicate with cells through transmission resources allocated by the network equipment (for example, frequency domain resources, or spectrum resources). The cell can belong to a macro base station (for example, a macro eNB or macro gNB), or to a base station corresponding to a small cell. Small cells here can include: metro cells, micro cells, pico cells, femto cells, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0094] In an embodiment of the present application, the terminal device may also be referred to as user equipment (UE), access terminal, user unit, user station, mobile station, mobile station, remote station, remote terminal, mobile device, user terminal, terminal, wireless communication device, user agent or user device.

[0095] A terminal device may be a device that provides voice / data connectivity to a user, such as a handheld device or vehicle-mounted device with wireless connection capabilities. Currently, some examples of terminal devices include: mobile phones, tablet computers, computers with wireless transceiver capabilities (such as laptops, PDAs, etc.), mobile internet devices (MIDs), virtual reality (VR) devices, augmented reality (AR) devices, wireless terminals in industrial control, wireless terminals in unmanned driving, wireless terminals in telemedicine, wireless terminals in smart grids, wireless terminals in transportation safety, wireless terminals in smart cities, wireless terminals in smart homes, cellular phones, cordless phones, session initiation protocol (SIP) phones, wireless local loop (WLL) stations, personal digital assistants (PDAs), handheld devices with wireless communication capabilities, computing devices or other processing devices connected to wireless modems, vehicle-mounted devices, wearable devices, terminal devices in 5G networks, or terminal devices in future-evolved public land mobile networks (PLMNs), etc.

[0096] Wearable devices, also known as wearable smart devices, are a general term for wearable devices that use wearable technology to intelligently design and develop wearable devices for daily wear, such as glasses, gloves, watches, clothing, and shoes. Wearable devices are portable devices that are worn directly on the body or integrated into the user's clothing or accessories. Wearable devices are not just hardware devices, but also achieve powerful functions through software support, data interaction, and cloud interaction. In a broad sense, wearable smart devices include those that are fully functional, large in size, and can achieve full or partial functions without relying on smartphones, such as smart watches or smart glasses, as well as those that only focus on a certain type of application function and need to be used in conjunction with other devices such as smartphones, such as various smart bracelets and smart jewelry for vital sign monitoring.

[0097] Furthermore, terminal devices can also be end devices in the Internet of Things (IoT) system. IoT is a crucial component of future information technology development. Its primary technical feature is connecting objects to the Internet through communications technology, thereby enabling intelligent networks that interconnect humans and machines, and objects and things. IoT technology, for example, utilizes narrowband (NB) technology to achieve massive connectivity, deep coverage, and power-saving terminals.

[0098] In addition, terminal devices can also include sensors such as smart printers, train detectors, and gas stations. Their main functions include collecting data (part of the terminal devices), receiving control information and downlink data from network devices, and sending electromagnetic waves to transmit uplink data to network devices.

[0099] In order to better understand the communication method provided in the embodiments of the present application, a brief explanation of the terms involved in the present application is first given.

[0100] (1) Cell, serving cell, candidate cell

[0101] A cell is described at a high level from the perspective of resource management, mobility management, or service units. The coverage area of ​​each network device can be divided into one or more cells, and each cell can correspond to one or more frequency bands. In other words, each cell can be considered an area formed by the coverage area of ​​one or more frequency bands. It should be noted that a cell can be an area within the coverage area of ​​a network device's wireless network.

[0102] The serving cell is the cell that the terminal device is currently residing in. In some mobility management technologies, the network device can provide one or more candidate cells for the terminal device. As the terminal device moves, the terminal device can switch to a candidate cell, which also becomes the target cell, and the target cell becomes the serving cell of the terminal device.

[0103] (2) Special cell (SpCell) and secondary cell (SCell)

[0104] FIG1 is a schematic diagram of the relationship between SpCell and SCell provided in an embodiment of the present application. The concepts of SpCell and SCell are described in detail below in conjunction with FIG1 .

[0105] A terminal device can communicate with one or more cells. When a terminal device communicates with a single cell, the cell can be called an SpCell. When a terminal device communicates with multiple cells, there are two ways: the terminal device communicates with multiple cells through dual connectivity (DC), or the terminal device communicates with multiple cells through carrier aggregation (CA). When a terminal device communicates with multiple cells through CA, the multiple cells are divided into primary cells (PCell) and SCells, where PCell can be called an SpCell. In the CA scenario, the SpCell can be a PCell.

[0106] When a terminal device communicates with multiple cells in a DC manner, as shown in Figure 1, there is a master cell group (MCG) and a secondary cell group (SCG). An MCG may include multiple cells, of which the cell used to initiate initial access is called a PCell, which can also be understood as the cell that serves as the overall commander among multiple cells is called a PCell, and the rest are called SCells. The PCell and SCell in the MCG are combined together through the CA technology. Similarly, an SCG may also include multiple cells, of which the cell used to initiate initial access is called a primary secondary cell (PSCell), which can also be understood as the cell that serves as the overall commander among multiple cells of the SCG is called a PSCell, and the rest are called SCells. The PSCell and SCell in the SCG are combined together through the CA technology. The SpCell includes the PCell in the MCG and the PSCell in the SCG. It should be understood that when a terminal device communicates with more than two cell groups, the concept of SpCell can be expanded accordingly. In the DC scenario, SpCell includes PCell and PSCell.

[0107] (3) Reference signal

[0108] Reference signals can be used for channel measurement, channel estimation, or beam quality monitoring. Reference signals involved in the embodiments of the present application may include, for example, a channel state information reference signal (CSI-RS) and a synchronization signal and physical broadcast channel block (SSB).

[0109] To facilitate understanding of the embodiments of the present application, a communication system applicable to the embodiments of the present application will be described in detail below in conjunction with Figure 2. Figure 2 is a schematic diagram of the network architecture of the communication system 100 provided in an embodiment of the present application. As shown in Figure 2, the communication system 100 may include a network device and a terminal device. Among them, the terminal device is located within the coverage of one or more cells (carriers) provided by the network device, and there may be one or more cells serving the terminal device. When there are multiple cells providing services for the terminal device, the terminal device may operate in accordance with CA or DC or coordinated multiple points transmission / reception (CoMP), and at least one cell may provide the terminal device with wireless resources corresponding to more than one transmission parameter set.

[0110] For example, as shown in FIG2 , terminal device 110 is simultaneously located in the cell of network device 120, the cell of network device 130, and the cell of network device 140. Network device 120 may be a macro base station (e.g., macroeNB), and network device 130 and network device 140 may be micro base stations (e.g., smalleNB). It should be understood that FIG2 is merely a schematic diagram, and the communication system 100 may also include other network devices such as core network devices, wireless relay devices, and wireless backhaul devices, which are not shown in FIG2 .

[0111] The embodiments of the present application do not limit the number of network devices, terminal devices, core network devices, and other network devices included in the communication system.

[0112] The network devices in the embodiments of the present application may correspond to different devices in communication systems of different types or standards, for example, in a 5G system, they correspond to network devices in 5G (such as gNB or ng-eNB), and in a 4G system, they correspond to network devices in 4G (such as eNB or en-gNB).

[0113] The network devices and terminal devices in the embodiments of this application can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on water; and can also be deployed in the air on aircraft, balloons, and artificial satellites. The embodiments of this application do not limit the application scenarios of the network devices and terminal devices.

[0114] It should be noted that the network architecture and business scenarios described in the embodiments of the present application are intended to more clearly illustrate the technical solutions of the embodiments of the present application, and do not constitute a limitation on the technical solutions provided in the embodiments of the present application. Ordinary technicians in this field can know that with the evolution of communication network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0115] In mobile communication systems, terminal devices (such as UEs) can report reference signal measurement results for their current serving cell and neighboring cells to network equipment (such as gNBs). These UE-reported measurement results are crucial for base stations to manage UEs. For example, if measurement results indicate that the channel quality of the current serving cell is better, the gNB can schedule more data packets and update its scheduling strategy. If measurement results indicate that the channel quality of a neighboring cell is better than that of the current serving cell, the gNB can instruct the UE to perform mobility management procedures such as cell handover and beam switching.

[0116] However, when the UE reports the measurement results, it will also occupy uplink transmission resources. How to efficiently perform measurement reporting is worth studying.

[0117] 3 shows a schematic flow chart of a method 200 for reporting measurement results. The method 200 mainly involves an L1 measurement reporting mechanism, where L1 refers to the physical layer, and the process of reporting L1 measurement results is mainly completed by the physical layer.

[0118] S210: The gNB sends L1 measurement configuration information to the UE. In response, the UE receives the L1 measurement configuration information.

[0119] The L1 measurement configuration information includes at least one of the following: a reference signal set to be measured, a reporting method, a reported measurement value, and an uplink resource used for reporting.

[0120] The reference signal set to be tested may include a reference signal of a serving cell and / or a reference signal of a neighboring cell.

[0121] Reporting methods include periodic reporting, aperiodic reporting, and semi-static reporting. Periodic reporting refers to the UE reporting periodically according to the period configured by the gNB. Aperiodic reporting refers to the gNB sending indication signaling to trigger the UE to report once. Semi-static reporting refers to the gNB sending indication signaling to trigger the UE to start periodic reporting thereafter.

[0122] The reported measurement quantity may include at least one of the following: reference signal received power (RSRP), reference signal received quality (RSRQ), signal to interference plus noise ratio (SINR), precoding matrix indication (PMI), channel quality information (CQI), and rank indication (RI). It should be understood that the above measurement quantity may be a cell-level measurement result or a beam-level (or reference signal-level) measurement result. A cell may have multiple beams (or multiple reference signals). The cell-level measurement result may include measurement results of different cells, for example, the average RSRP value of cell 1, the average RSRP value of cell 2, etc. The beam-level (or reference signal-level) measurement result may include measurement results of different beams (or different reference signals), for example, the RSRP value of beam 1 (or SSB 1), the RSRP value of beam 2 (or SSB 2), etc.

[0123] The uplink resources used for reporting include physical uplink control channel (PUCCH) resources and / or physical uplink shared channel (PUSCH) resources. Specifically, the gNB can instruct the UE to report the measurement results on the PUCCH or PUSCH.

[0124] S220: The UE measures the reference signal to be measured according to the L1 measurement configuration information to obtain an L1 measurement result.

[0125] In this step, the UE can measure the reference signals to be measured based on the L1 measurement configuration information configured by the gNB and obtain L1 measurement results. The reference signals to be measured and the measurement quantities to be measured are both configured by the gNB. In other words, the UE can obtain the reference signal set to be measured and the measurement quantities to be reported from the L1 measurement configuration information.

[0126] S230, the gNB sends an indication signaling to the UE. Correspondingly, the UE receives the indication signaling sent by the gNB.

[0127] It should be understood that this step is optional.

[0128] When the gNB instructs the UE to use aperiodic reporting or semi-static reporting, the gNB needs to send an indication signaling to the UE. This indication signaling is used to indicate whether the UE uses aperiodic reporting or semi-static reporting. When the gNB instructs the UE to use periodic reporting, the gNB does not need to send an indication signaling to the UE.

[0129] S240: The UE reports the L1 measurement result according to the L1 measurement configuration information. Correspondingly, the gNB receives the L1 measurement result.

[0130] In this step, the UE may report the L1 measurement results based on the L1 measurement configuration information configured by the gNB. Specifically, the UE may obtain the reporting mode and uplink resources used for reporting from the L1 measurement configuration information. When reporting the L1 measurement results, the UE may report the L1 measurement results based on the reporting mode and uplink resources configured by the gNB.

[0131] For example, the L1 measurement result can be reported to the gNB via L1 uplink control information (UCI), where the UCI can be carried on the PUCCH or PUSCH. This measurement result is referred to as the L1 measurement result, i.e., the measurement result obtained by the UE's physical layer (L1 layer) of the received reference signal.

[0132] In the aforementioned L1 measurement reporting mechanism, UE reporting consumes a large amount of uplink resources and consumes significant UE power. For example, when periodic reporting is configured, the gNB must provide periodic PUCCH resources. Even if the UE's channel conditions do not change significantly, these periodic PUCCH resources must be continuously occupied and reported, wasting uplink resources and consuming UE power.

[0133] Figure 4 shows a schematic flow chart of another method 300 for reporting measurement results. The method 300 mainly involves an L3 measurement reporting mechanism, where L3 refers to the radio resource control (RRC) layer, and the L3 measurement result reporting process must be completed via the RRC layer.

[0134] S310: The gNB provides L3 measurement configuration information to the UE. In response, the UE receives the L3 measurement configuration information.

[0135] The L3 measurement configuration information may include at least one of the following: a frequency to be measured, a reference signal set to be measured, a reporting method, and a reported measurement value.

[0136] The frequency point to be measured refers to the frequency domain location information to be measured. The reference signal set to be measured includes the reference signal of the serving cell and / or the reference signal of the neighboring cell.

[0137] Reporting methods include periodic reporting and event-triggered reporting. Periodic reporting refers to the UE reporting periodically according to the period configured by the gNB. Event-triggered reporting means that the gNB can configure certain events for the UE, and the UE reports when it determines that the event is triggered (or the event conditions are met). The events configured by the gNB for the UE may include the following:

[0138] Event A1: The measurement result of the serving cell is higher than the preset threshold.

[0139] Event A2: The measurement result of the serving cell is lower than the preset threshold.

[0140] Event A3: The measurement result of the neighboring cell is higher than the measurement result of the serving cell (or special cell SpCell) by a preset threshold.

[0141] Event A4: The measurement result of the neighboring cell is higher than the preset threshold.

[0142] Event A5: The measurement result of the serving cell is lower than the first threshold, and the measurement result of the neighboring cell is higher than the second threshold.

[0143] Event A6: The measurement result of the neighboring cell is higher than the measurement result of the secondary cell by a preset threshold.

[0144] For example, there is an A3 event: the channel quality of the neighboring cell is higher than the channel quality of the current serving cell by a preset threshold. For example, there is an A5 event: the channel quality of the current serving cell is lower than the first threshold, and the channel quality of the neighboring cell is higher than the second threshold.

[0145] It should be noted that the gNB can specify which measurement result triggers the above events. That is, the gNB specifies whether the condition for the UE to determine whether the event is triggered is the RSRP measurement result, the RSRQ measurement result, or the SINR measurement result.

[0146] The reported measurement quantity may include at least one of the following: RSRP, RSRQ, SINR, PMI, CQI, and RI.

[0147] S320: The UE measures the reference signal to be measured according to the L3 measurement configuration information to obtain an L3 measurement result.

[0148] In this step, the UE can measure the reference signal to be measured based on the L3 measurement configuration information configured by the gNB and obtain the L3 measurement results. The frequency to be measured, the reference signal to be measured, and the measurement quantity to be measured are all configured by the gNB. In other words, the UE can obtain the frequency to be measured, the reference signal set to be measured, and the measurement quantity to be reported from the L3 measurement configuration information.

[0149] At step S330 , the UE reports the L3 measurement result based on the L3 measurement configuration information. Correspondingly, the gNB receives the L3 measurement result.

[0150] In this step, the UE may report the L3 measurement results according to the L3 measurement configuration information configured by the gNB. In other words, the UE may obtain the reporting mode from the L3 measurement configuration information and, when reporting the L3 measurement results, may report the L3 measurement results according to the reporting mode configured by the gNB.

[0151] It should be understood that the L3 measurement results are reported to the gNB via RRC messages. Specifically, the UE's L3 measurement results are filtered by the RRC layer and reported via RRC messages.

[0152] In the above-mentioned L3 measurement reporting mechanism, although the event-triggered reporting mechanism can reduce the uplink resources used for reporting and reduce UE power consumption, the L3 reporting process is slow, the RRC processing process is slow, and the RRC message packaging and sending process is also slow. As a result, the measurement results arrive at the gNB late, resulting in untimely reporting.

[0153] In response to the above-mentioned L1 and L3 measurement reporting mechanisms, the present application provides a communication method and a communication device, which designs an event-triggered reporting mechanism, thereby reducing the UE's uplink resource occupancy and the UE's reporting power consumption while reporting measurement results quickly and timely.

[0154] Figure 5 is a schematic flow chart of a communication method 400 provided in an embodiment of the present application. It should be understood that the communication method 400 can be applied to a terminal device. The terminal device here can refer to the terminal device itself or to a processor, module, chip, or chip system that implements the method in the terminal device, and this application does not limit this.

[0155] S410: The terminal device receives measurement configuration information sent by the network device. Correspondingly, the network device sends the measurement configuration information to the terminal device.

[0156] The measurement configuration information may include an event triggering condition, and the event triggering condition may be understood as a preset condition that a measurement result of a certain measurement quantity must satisfy.

[0157] In some embodiments, the event trigger condition may include a cell-level event trigger condition, a beam-level event trigger condition (ie, a reference signal-level event trigger condition), and a reference signal set-level event trigger condition.

[0158] Specifically, the cell-level event triggering conditions may include any of the following: the measurement result of the serving cell is higher than the preset threshold; the measurement result of the serving cell is lower than the preset threshold; the measurement result of the neighboring area is higher than the measurement result of the serving cell / special cell. The preset threshold; the measurement result of the neighboring area is higher than the preset threshold; the measurement result of the serving cell is lower than the first threshold, and the measurement result of the neighboring area is higher than the threshold; the measurement result of the neighboring area is higher than the measurement result of the secondary cell by a preset threshold.

[0159] The event trigger conditions at the beam level may include any of the following: the measurement result of the beam being used by the serving cell is higher than the preset threshold; the measurement result of the beam being used by the serving cell is lower than the preset threshold; the measurement result of a beam in the neighboring cell is higher than the preset threshold; the measurement result of a beam in the neighboring cell is higher than the preset threshold; the measurement result of a beam in the neighboring cell is higher than the preset threshold; the measurement result of the beam being used by the serving cell is lower than the third threshold, and the measurement result of a beam in the neighboring cell is higher than the fourth threshold; the measurement result of a beam in the neighboring cell is higher than the preset threshold.

[0160] The event triggering conditions at the reference signal set level may include any one of the following: the measurement result of the reference signal set corresponding to the serving cell is higher than the preset threshold; the measurement result of the reference signal set corresponding to the serving cell is lower than the preset threshold; the measurement result of the reference signal set corresponding to the neighboring cell is higher than the preset threshold than the measurement result of the reference signal set corresponding to the serving cell / special cell; the measurement result of the reference signal set corresponding to the neighboring cell is higher than the preset threshold; the measurement result of the reference signal set corresponding to the serving cell is lower than the fifth threshold, and the measurement result of the reference signal set corresponding to the neighboring cell is higher than the sixth threshold; the measurement result of the reference signal set corresponding to the neighboring cell is higher than the preset threshold than the measurement result of the reference signal set corresponding to the secondary cell.

[0161] In some embodiments, the network device may pre-configure different events for the terminal device, or some events may be pre-defined in the protocol. The events may include: cell-level triggering events (i.e., A events), beam-level triggering events (i.e., X events), and reference signal set-level triggering events (i.e., Y events).

[0162] The cell-level triggering event (A event) can refer to S310, and the A event may include events A1 to A6. For example, when the RSRP of each beam in the measurement result of the serving cell beam is less than a preset threshold, the terminal device reports the measurement result to the network device.

[0163] Beam-level trigger events (X events) can include the following:

[0164] Event X1: The measurement result of the beam being used by the serving cell is higher than the preset threshold.

[0165] Event X2: The measurement result of the beam being used by the serving cell is lower than the preset threshold.

[0166] Event X3: The measurement result of a beam in the neighboring cell is higher than the measurement result of the beam being used by the serving cell (or special cell SpCell) by a preset threshold.

[0167] Event X4: The measurement result of a beam in the neighboring cell is higher than the preset threshold.

[0168] Event X5: The measurement result of the beam being used by the serving cell is lower than the third threshold, and the measurement result of a beam in the neighboring cell is higher than the fourth threshold.

[0169] Event X6: The measurement result of a beam in the neighboring cell is higher than the measurement result of a beam in the current secondary cell by a preset value.

[0170] Trigger events (Y events) at the reference signal set level may include the following:

[0171] Event Y1: The measurement result of the reference signal set of the corresponding serving cell is higher than the preset threshold.

[0172] Event Y2: The measurement result of the reference signal set of the corresponding serving cell is lower than the preset threshold.

[0173] Event Y3: The measurement result of the reference signal set corresponding to the neighboring cell is higher than the measurement result of the reference signal set corresponding to the serving cell (or special cell SpCell) by a preset threshold.

[0174] Event Y4: The measurement result of the reference signal set of the corresponding neighboring cell is higher than the preset threshold.

[0175] Event Y5: The measurement result of the reference signal set corresponding to the serving cell is lower than the fifth threshold, and the measurement result of the reference signal set corresponding to the neighboring cell is higher than the sixth threshold.

[0176] Event Y6: The measurement result of the reference signal set corresponding to the neighboring cell is higher than the measurement result of the reference signal set corresponding to the current secondary cell by a preset threshold.

[0177] It should be understood that there may be other event contents. This application does not limit the specific event content, and the above event content is only for illustrative purposes.

[0178] It should be noted that the embodiments of the present application do not limit the sizes of the above-mentioned preset threshold, first threshold, second threshold, third threshold and fourth threshold. It should be understood that the preset threshold may be greater than or equal to 0. In some embodiments, when the preset threshold is 0, it may be considered that the cell-level measurement result of a certain neighboring cell / candidate cell is higher than the cell-level measurement result of the current serving cell. In some embodiments, when the preset threshold is 0, it may be considered that the measurement result of a certain beam of the neighboring cell is higher than the measurement result of the beam being used by the serving cell / special cell. In some embodiments, when the preset threshold is 0, it may be considered that the measurement result of the reference signal set of the corresponding neighboring cell is higher than the measurement result of the reference signal set of the corresponding serving cell / special cell.

[0179] It should be noted that the network device specifies which measurement quantity the above measurement result is, for example, an RSRP measurement result, an RSRQ measurement result, an SINR measurement result, etc. Exemplarily, when the RSRP of each beam in the measurement results of the beam of the serving cell is less than a preset threshold, the terminal device reports the measurement result corresponding to the reference signal to the network device.

[0180] It is understandable that the event triggering condition implicitly includes the triggering event granularity and the triggering event type.

[0181] The trigger event granularity may include any of the following: UE-level granularity, cell-level granularity, reference signal set-level granularity, beam-level granularity / reference signal-level granularity.

[0182] UE-level granularity: A unified event is used for each UE. Specifically, the network device assigns an event (e.g., event A1) to the UE. This means that, regardless of evaluating different reference signal sets or different cells, when the serving cell measurement result (e.g., RSRP measurement result) exceeds a preset threshold, the UE reports the measurement result. The RSRP measurement result can be the average of the RSRP measurement results of multiple reference signals in the serving cell.

[0183] Cell-level granularity: Different events can be configured for different neighboring cells / candidate cells. Specifically, for candidate cell 1, the network device will assign one event (such as Event 1), and for candidate cell 2, the network device will assign another event (such as Event 2). Event 1 and Event 2 can correspond to different thresholds for Event A1. For example, Event 1 is when the measurement result of the serving cell exceeds threshold value x, and Event 2 is when the measurement result of the serving cell exceeds threshold value y.

[0184] Reference signal set-level granularity: Different events can be configured for different reference signal sets to be tested. Specifically, when the UE evaluates whether the reference signals in different sets meet the triggering conditions, the corresponding events for each reference signal set are different. For example, for reference signal set 1, a report is generated when the measurement result of the neighboring cell is x higher than the measurement result of the serving cell; for reference signal set 2, a report is generated when the signal quality of the neighboring cell is y higher than the signal quality of the serving cell, enabling more refined control.

[0185] Beam-level granularity / reference signal-level granularity: Different events can be configured for different beams / reference signals to be tested. Specifically, network devices can assign different events to different beams / reference signals to be tested. For example, for Beam 1 / Reference Signal 1, a report is sent when the neighboring cell's measurement result is x higher than the serving cell's measurement result; for Beam 2 / Reference Signal 2, a report is sent when the neighboring cell's signal quality is y higher than the serving cell's signal quality, enabling more refined control.

[0186] The trigger event type may include any of the following: an event of a cell-level measurement result, an event of a beam-level measurement result, or an event of an aggregate-level measurement result.

[0187] An event of a cell-level measurement result, for example, a cell-level measurement result of a neighboring cell / candidate cell is higher than the cell-level measurement result of the current serving cell, or higher than a preset threshold. For example, the cell-level measurement result can be the average of the measurement results of multiple reference signals of the cell.

[0188] Beam-level measurement events, such as when a neighboring / candidate cell's beam-level measurement result is higher than the beam-level measurement result of the currently serving cell's beam, or exceeds a preset threshold. Beam-level measurements generally refer to the measurement result of a reference signal, meaning one reference signal corresponds to one beam direction.

[0189] An event involving set-level measurement results, such as when the average measurement results of multiple reference signals in a reference signal set is higher than the measurement results of the beam / reference signal currently in use by the serving cell, or exceeds a preset threshold. Another example is when the measurement result of the strongest reference signal in a reference signal set is higher than the measurement result of the beam / reference signal currently in use by the serving cell, or exceeds a preset threshold.

[0190] Optionally, the measurement configuration information may further include a reference signal to be measured, a frequency point to be measured, and a report quantity to be measured. The frequency point to be measured refers to the frequency domain location information to be measured. The report quantity to be measured may include at least one of the following: RSRP, RSRQ, SINR, PMI, CQI, RI.

[0191] The reference signals to be tested include the reference signal of the serving cell and / or the reference signals of neighboring cells. In mobility management scenarios, neighboring cells are also called candidate cells. The UE may later switch to this candidate cell, that is, the candidate cell is regarded as the target cell for handover, and the target cell becomes the UE's new serving cell. The reference signals to be tested can be SSB, CSI-RS, or other types of reference signals. Different reference signals correspond to different beam directions.

[0192] It should be understood that the reference signal to be measured may be a set of one or more reference signals, where the reference signal set includes the reference signal of the serving cell and / or the reference signal of the neighboring cell. It should be understood that the reference signal of the serving cell and the reference signal of the neighboring cell can both be distinguished by a reference signal identifier (e.g., a reference signal ID). In other words, the measurement configuration information may include a set of one or more reference signals, and each reference signal set may include the identifier of the reference signal of the serving cell and / or the neighboring cell.

[0193] Optionally, the measurement configuration information may further include a preset rule, and the terminal device may select the measurement result to be reported based on the preset rule. The preset rule may include at least one of the following: selecting the measurement result of the candidate cell based on signal strength; selecting the measurement result of the reference signal set based on signal strength; selecting the measurement result of the reference signal based on signal strength; selecting the measurement result based on the measurement result of the special cell; and selecting the measurement result based on the measurement result of the reference signal received power (RSRP).

[0194] It should be noted that the above event content (including event granularity and event type) can be generated by the gNB managing the current serving cell (i.e., the serving gNB) or by the gNB managing a neighboring cell / candidate cell (i.e., the neighbor gNB or candidate gNB). If generated by a neighbor gNB / candidate gNB, the neighbor gNB / candidate gNB sends the event content to the serving gNB, which then sends it to the UE.

[0195] S420: The PHY layer of the terminal device measures the reference signal to be measured, determines that the event triggering condition is met, and sends first indication information to the MAC layer.

[0196] Specifically, when the physical PHY layer of the terminal device measures the reference signal to be measured and determines that the first measurement result of the reference signal to be measured meets the event triggering condition, the PHY layer will send first indication information to the MAC layer. This first indication information can be used to indicate that the event is in a triggered state, that is, the first measurement result of the reference signal to be measured meets the event triggering condition. Correspondingly, after the MAC layer receives the first indication information, the MAC layer triggers reporting, or enters a triggered reporting state. Subsequently, the MAC layer can send the second measurement result to the network device.

[0197] It should be noted that the first measurement result and the second measurement result may be the same, different, or partially the same. The first measurement result is used to determine whether the event triggering condition is met, and the second measurement result is the measurement result that the network device indicates the terminal device needs to report. The first measurement result is the measurement result corresponding to the first measurement quantity, and the second measurement result is the measurement result corresponding to the second measurement quantity. It should be understood that the first measurement quantity and the second measurement quantity are both specified by the network device. Specifically, the terminal device can obtain the first measurement quantity and the second measurement quantity from the measurement configuration information. Among them, the first measurement quantity may include at least one of the following: reference signal received power RSRP, reference signal received quality RSRQ, signal to interference and noise ratio SINR. The second measurement quantity may include at least one of the following: reference signal received power RSRP, reference signal received quality RSRQ, signal to interference and noise ratio SINR, precoding matrix indication PMI, channel quality information CQI, rank indication RI.

[0198] For example, the first measurement result is an RSRQ measurement result, and the reported second measurement result is also an RSRQ measurement result. For another example, the first measurement result is an RSRP measurement result, but the reported second measurement result is a PMI measurement result. For another example, the first measurement result is an RSRP measurement result, and the reported second measurement result includes an RSRP measurement result, a PMI measurement result, a CQI measurement result, and an RI measurement result.

[0199] It should be understood that after the terminal device receives the measurement configuration information from the network device, the PHY layer of the terminal device can measure the reference signal to be measured (such as the reference signal of the serving cell and / or the candidate cell). The reference signal can be an SSB, CSI-RS, or other type of reference signal, and different reference signals correspond to different beam directions. The PHY layer of the terminal device measures different reference signals of the serving cell and / or candidate cell to obtain beam-level measurement results.

[0200] Exemplarily, the reference signals of the serving cell are SSB 1, SSB 2, CSI-RS 1, and CSI-RS 2, the reference signals of the first candidate cell are SSB 1, SSB 2, CSI-RS 1, and CSI-RS 2, and the reference signals of the second candidate cell are SSB 1, SSB 2, CSI-RS 1, and CSI-RS 2, where the first candidate cell and the second candidate cell are any cells in the candidate cells. The PHY layer of the terminal device needs to measure the above reference signals separately to obtain 12 beam-level measurement results.

[0201] The aforementioned measurement results include beam-level measurement results, reference signal set-level measurement results, and cell-level measurement results. After the terminal device measures the reference signal to be measured and obtains the beam-level measurement result, it can further determine the reference signal set-level measurement result and the cell-level measurement result, and send the measurement results to the network device.

[0202] It should be understood that in the embodiments of the present application, to facilitate the distinction between measurement results of different granularities, beam measurement results, reference signal set measurement results, and cell measurement results are respectively referred to as beam-level measurement results, reference signal set-level measurement results, and cell-level measurement results. When describing a measurement result separately, the measurement result may include at least one of the beam-level measurement result, the reference signal set-level measurement result, and the cell-level measurement result. The beam-level measurement result may also be referred to as the reference signal-level measurement result.

[0203] The calculation method of the cell-level measurement result may refer to the calculation method of the cell-level measurement result in the prior art. The calculation method of the reference signal set-level measurement result is described in detail below using the first reference signal set as an example.

[0204] The first reference signal set may include multiple reference signals. The measurement result corresponding to the first reference signal set is determined by the beam measurement results corresponding to the multiple reference signals in the first reference signal set. The terminal device may determine the measurement result of the first reference signal set based on the beam-level measurement result. For example, the PHY layer of the terminal device may measure the multiple reference signals (i.e., multiple beams) under the first reference signal set to determine the measurement result of a single beam, and then determine the measurement result of the first reference signal set based on the measurement result of the single beam.

[0205] S430: The MAC layer of the terminal device sends the measurement result to the network device via MAC layer signaling according to the first indication information. Correspondingly, the network device receives the measurement result.

[0206] In some embodiments, the MAC layer receives the first indication information, triggering the MAC layer to report; and sends the measurement result to the network device via MAC layer signaling. Specifically, the PHY layer can measure the reference signal to be measured. If it is determined that the measurement result meets the event triggering condition, the PHY layer can send the first indication information to the MAC layer, thereby triggering the MAC layer to report. Subsequently, the terminal device can send the measurement result via MAC layer signaling. In other words, the MAC layer can enter a reporting trigger state. When the MAC layer is in the reporting trigger state, the measurement result can be sent via MAC layer signaling.

[0207] In some embodiments, when the MAC layer receives the first indication information, it starts a periodic reporting timer; when the periodic reporting timer times out, it triggers the MAC layer to report and restarts the periodic reporting timer, and sends the measurement results through MAC layer signaling. Specifically, after the MAC layer receives the first indication information sent by the PHY layer, the terminal device will start the periodic reporting timer. When the periodic reporting timer times out, the MAC layer will trigger the reporting process again; after the terminal device sends the measurement results, if the PHY layer determines that the event is still in a triggered state, or the MAC receives the first indication information but does not receive the second indication information below, the terminal device will restart the periodic reporting timer. This can avoid repeatedly sending the first indication information and reduce the complexity of the interaction between layers.

[0208] In some embodiments, after the measurement result is sent to the network device via MAC layer signaling, the MAC layer reporting trigger is canceled. Specifically, if the MAC layer reports the measurement result via MAC layer signaling, the MAC layer reporting trigger can be canceled, that is, the MAC layer reporting trigger state can be canceled to avoid being in a triggered state and continuously using uplink resources for reporting. If the MAC layer still needs to report the measurement result, it needs to receive the first indication information again or the periodic reporting timer expires.

[0209] Optionally, when the PHY layer of the terminal device determines that the measurement result of the reference signal to be measured (such as the first measurement result mentioned above) still meets the event triggering condition, it will continue to send the first indication information to the MAC layer, triggering the MAC layer to report, and then send the measurement result to the network device through MAC layer signaling.

[0210] In some embodiments, when the MAC layer receives the first indication information, it starts a periodic reporting timer; when the PHY layer determines that the event triggering condition is not met, it sends a second indication information to the MAC layer; and the MAC layer stops the periodic reporting timer based on the second indication information. Specifically, when the MAC layer of the terminal device receives the first indication information, it can start the periodic reporting timer. If the PHY layer of the terminal device determines that the measurement result of the reference signal to be measured (such as the first measurement result mentioned above) does not meet the event triggering condition, the PHY layer will send a second indication information to the MAC layer. The second indication information can be used to indicate that the event is no longer in a triggered state, that is, the first measurement result of the reference signal to be measured does not meet the event triggering condition; then, the MAC layer can stop the periodic reporting timer based on the second indication information.

[0211] Optionally, after receiving the second indication information, the MAC layer may trigger a final reporting process, that is, report the measurement result to the network device again. Further optionally, the measurement result may indicate that the event triggering condition is no longer met subsequently.

[0212] Optionally, the PHY layer of the terminal device determines whether the measurement result (such as the first measurement result described above) satisfies the event triggering condition at a preset time interval, or the PHY layer of the terminal device determines whether the measurement result (such as the first measurement result described above) satisfies the event triggering condition within each preset time period. Exemplarily, the PHY layer of the terminal device may periodically determine (for example, once every 5ms) whether the event is triggered; or the PHY layer of the terminal device determines whether the event is triggered within each preset time period (for example, once within each 5ms time period).

[0213] In some embodiments, the MAC layer signaling may include a medium access control layer control element MAC CE, or other control signaling, for example, MAC layer control signaling that may appear in future network systems.

[0214] It should be understood that when there are available uplink resources, the terminal device can generate a MAC CE; the terminal device can send a MAC CE to the network device through MAC layer signaling, and the MAC CE carries the measurement result (such as the second measurement result mentioned above). Furthermore, after the terminal device sends the MAC CE, the MAC layer can cancel the trigger report. If subsequent reporting of measurement results is required, the MAC layer needs to wait for the triggering of the next reporting process, for example, the above-mentioned periodic reporting timer expires, or the first indication information of the PHY layer is received.

[0215] The MAC CE may include at least one of the following: an identifier of a reference signal set, an identifier of a serving cell, an identifier of a candidate cell, an identifier of a secondary cell, an identifier of a reference signal, a quantity to be measured, and a measurement result corresponding to the quantity to be measured. For example, the MAC CE may include the measurement result of the RSRP of reference signal 1 of serving cell 1. In some possible solutions, the identifier of the serving cell may correspond to an identifier of a special cell.

[0216] In one example, the format of the MAC CE may be as shown in Table 1. The MAC CE may include the identifier of the candidate cell / serving cell / reference signal set (i.e., Candidate / Serving / Reference Signal Set ID), the identifier of the special cell reference signal (i.e., RS ID of the SpCell), and the L1 measurement result of the special cell (i.e., L1 result of SpCell). Optionally, the MAC CE may also include the identifier of the secondary cell (i.e., SCell ID), the identifier of the special cell reference signal (i.e., RS ID of the SCell), and the measurement result of the secondary cell (L1 result of SCell).

[0217] The L1 result may include the quantity to be measured and the measurement result corresponding to the quantity to be measured. The quantity to be measured can be understood as the type of reported measurement quantity (for example, RSRP, RSRQ, SINR, or other measurement quantity types). The measurement result corresponding to the quantity to be measured is the measurement result corresponding to the measurement quantity type (value of the report).

[0218] As mentioned above, in non-carrier aggregation and non-dual connectivity scenarios, SpCell is the only candidate cell; in carrier aggregation scenarios, SpCell is the primary cell PCell; in dual connectivity scenarios, SpCell includes the primary cell PCell and the primary and secondary cells PSCell.

[0219] Table 1

[0220] In another example, the format of MAC CE may be as shown in Table 2. MAC CE may include Ti, RS ID of the SpCell, L1 result of SpCell. Optionally, MAC CE may also include SCell ID, RS ID of the SCell, L1 result of SCell.

[0221] Wherein, Ti refers to the i-th candidate cell (or candidate cell identified as i) or the i-th reference signal set (or reference signal set identified as i). When Ti is 1, it means that the candidate cell or reference signal set meets the event triggering condition, or it can represent that the event corresponding to the candidate cell or reference signal set is triggered; when Ti is 0, it means that the candidate cell or reference signal set does not meet the event triggering condition, or it can represent that the event corresponding to the candidate cell or reference signal set is not triggered. For other parameters, please refer to the explanation in Table 1.

[0222] Table 2

[0223] In some embodiments, the PHY layer measures the first reference signal and the second reference signal, determines that both the first reference signal and the second reference signal meet an event triggering condition, and sends first indication information to the MAC layer. The MAC layer sends the measurement result corresponding to the first reference signal to the network device via first MAC layer signaling based on the first indication information and a preset rule. Furthermore, the measurement result corresponding to the second reference signal may also be sent to the network device via second MAC layer signaling.

[0224] The preset rule may include at least one of the following: selecting a measurement result of a candidate cell based on signal strength; selecting a measurement result of a reference signal set based on signal strength; selecting a measurement result of a reference signal based on signal strength; selecting a measurement result based on a measurement result of a special cell; or selecting a measurement result based on a measurement result of reference signal received power (RSRP). The measurement result may include a cell-level measurement result, a beam-level measurement result, and a reference signal set-level measurement result.

[0225] For example, when the terminal device has available uplink resources, the terminal device generates a MAC CE to send the measurement results. When the uplink resources may not be sufficient to send a complete MAC CE, for example, a certain uplink resource can send 5 bytes of content, but the MAC CE generated by the terminal device to report the measurement results has 10 bytes, the terminal device needs to truncate the MAC CE and report it. When the terminal device truncates the report, the terminal device can, for example, select part of the content for reporting according to the following rules:

[0226] Rule 1: Select candidate cells or reference signal set measurement results based on signal strength

[0227] For example, if multiple events are triggered, the terminal device selects the measurement result of the candidate cell or reference signal set with the strongest signal strength among the triggered events and includes the selected measurement result in the MAC CE. If there is still room for uplink resources, the terminal device can select the measurement result of the second strongest candidate cell or reference signal set to include in the MAC CE, and so on. When there are insufficient uplink resources to include additional measurement results, the terminal device no longer selects measurement results to include in the MAC CE, that is, truncation is performed.

[0228] Rule 2: Select the measurement result of the reference signal based on the signal strength

[0229] For example, if there are multiple reference signals in the candidate cell or reference signal set corresponding to a triggered event, the terminal device selects the strongest X reference signals and includes them in the MAC CE, where X can be specified as 1, a special value, or a value configured by the network device. If the uplink resources can be used to include additional measurement results, the terminal device selects the strongest X reference signals from the candidate cell or reference signal set corresponding to another triggered event and includes them in the MAC CE, and so on. When the uplink resources are insufficient to include additional measurement results, the terminal device no longer selects measurement results to include in the MAC CE, and truncation is required.

[0230] Rule 3: Select measurement results based on the measurement results of special cells

[0231] For example, if the candidate cell corresponding to a certain triggered event adopts carrier aggregation, the terminal device selects the SpCell measurement result to be included in the MAC CE, but does not include the SCell measurement result in the MAC CE. Including the SpCell measurement result in the MAC CE can be understood as the MAC CE including the SpCell measurement result.

[0232] Rule 4: Select measurement results based on RSRP measurement results

[0233] The terminal device selects the RSRP measurement result to be included in the MAC CE instead of SINR, PMI or other measurement results.

[0234] Optionally, the UE may select which measurement result of the measurement quantity to be configured by the network device. For example, the network device configures the terminal device to select RSRP to be incorporated into the MAC CE, or select SINR to be incorporated into the MAC CE, or select measurement results of other measurement quantity types to be incorporated into the MAC CE when MAC CE truncation is required.

[0235] It should be noted that, in addition to the above-mentioned preset rules, other preset rules may also be included. In one possible implementation, the network device may configure different priorities of candidate cells / reference signal sets / reference signals. When the terminal device needs to perform MAC CE truncation, it selects the measurement result group corresponding to the candidate cell / reference signal set / reference signal with a high priority and includes it in the MAC CE. In addition, the above-mentioned preset rules may be used simultaneously or partially. Optionally, the network device may specify the preset rules to be used in the measurement configuration information, or the preset rules to be used may be predefined in the protocol.

[0236] If uplink resources are insufficient, the measurement results corresponding to the first reference signal and the measurement results corresponding to the second reference signal cannot be sent simultaneously via the first MAC layer signaling. In this case, the MAC layer may filter based on preset rules and select the measurement results corresponding to the first reference signal that meet the preset rules, so that the first MAC layer signaling prioritizes sending the measurement results corresponding to the first reference signal. If uplink resources are available later, the measurement results corresponding to the second reference signal may continue to be sent.

[0237] In other words, if there are multiple triggered events, but due to limited uplink resources, the MAC CE generated by the terminal device can only include the measurement results of some of the triggered events. After the terminal device sends this MAC CE, the terminal device only cancels the reporting trigger corresponding to this part of the events included in the MAC CE, but does not cancel the reporting trigger corresponding to other events, that is, it is still in the triggered state, waiting for the next uplink resource to generate a MAC CE report.

[0238] It should be understood that in this embodiment, the first indication information sent by the PHY layer to the MAC layer may be sent more than once. That is, in some embodiments, the PHY layer measures the first reference signal, determines that the first reference signal meets the event trigger condition, and sends the first indication information to the MAC layer; in addition, the PHY layer may also measure the second reference signal, and when it determines that the second reference signal meets the event trigger condition, it may send the first indication information to the MAC layer again.

[0239] In some embodiments, when there are no available uplink resources to send MAC layer signaling, the terminal device may send a scheduling request (SR) message to the network device. The scheduling request message is used to request uplink resources for sending measurement results. Correspondingly, the network device receives the scheduling request message. Specifically, when there are no available uplink resources to send MAC layer signaling (such as MAC CE), the MAC layer of the terminal device triggers an SR and may instruct the PHY layer to send a PUCCH SR.

[0240] In some embodiments, a terminal device may receive a first scheduling request configuration and a second scheduling request configuration sent by a network device; when the data volume of the measurement result is greater than or equal to a first preset value, the terminal device may select the first scheduling request configuration to send the scheduling request information; when the data volume of the measurement result is less than the first preset value, the terminal device may select the second scheduling request configuration to send the scheduling request information. Correspondingly, the network device may send the first scheduling request configuration and the second scheduling request configuration to the terminal device, where the first scheduling request configuration is used when the data volume of the measurement result reported by the terminal device is greater than or equal to the first preset value, and the second scheduling request configuration is used when the data volume of the measurement result reported by the terminal device is less than the first preset value.

[0241] The network device can provide multiple sets of PUCCH SR configurations to the terminal device, and each set of PUCCH SR configurations can be suitable for different numbers of triggering events. For example, the network device provides two sets of PUCCH SR configurations to the terminal device, the first set is used for a smaller number of triggering events (for example, less than M), and the second set is used for a larger number of triggering events (for example, greater than or equal to M). When the terminal device has less than M triggered events, the first set of PUCCH SR resources can be used. After the network device receives the PUCCH SR resources, it knows that the number of triggered events is less than M, and then it can provide less uplink resources to the terminal device. When the terminal device has greater than or equal to M triggered events, the second set of PUCCH SR resources can be used. After the network device receives the PUCCH SR resources, it knows that the number of triggered events is greater than or equal to M, and then it can provide more uplink resources to the terminal device. This method is conducive to the reasonable allocation of uplink resources by the network device, avoiding the situation where there are too few uplink resources to send MAC CE, and also avoiding the problem of excessive waste of uplink resources.

[0242] In this embodiment, the PHY layer of the terminal device can measure the reference signal to be measured. If it is determined that the measurement result obtained by the measurement meets the event trigger condition, the PHY layer can send a first indication information to the MAC layer, so that the MAC layer is in a reporting trigger state. Subsequently, the terminal device can send the measurement result through MAC layer signaling (such as MAC CE), the network device can receive the measurement result, and can update the scheduling strategy or perform mobility management such as cell switching and beam switching based on the measurement result.

[0243] It should be understood that MAC layer signaling (such as MAC CE), which is an L2 signaling, is generated and sent faster than L3 signaling. In addition, the measurement result will be reported only when the measurement result meets the event triggering condition; when the measurement result does not meet the event triggering condition, the measurement result will not be reported, thereby reducing the uplink resource occupancy. In other words, the present application judges the event triggering through the PHY layer and sends the measurement result through MAC layer signaling. When the event is triggered and there are uplink resources, the terminal device can quickly and timely report the measurement result, and can also reduce the uplink resource occupancy of the terminal device.

[0244] Figure 6 is a schematic flow chart of another communication method 500 provided in an embodiment of the present application. It should be noted that the difference between communication method 500 and communication method 400 is that communication method 500 measures the reference signal to be measured through the PHY layer or MAC layer, and the MAC layer determines whether the event triggering condition is met, while communication method 400 measures the reference signal to be measured through the PHY layer and determines whether the event triggering condition is met. Therefore, some of the contents of communication method 500 can refer to communication method 400.

[0245] As shown in FIG6 , the communication method 500 includes at least the following steps.

[0246] S510: The network device sends measurement configuration information to the terminal device. Correspondingly, the terminal device receives the measurement configuration information.

[0247] The measurement configuration information may include an event triggering condition, and the event triggering condition may be understood as a preset condition that a measurement result of a certain measurement quantity must satisfy.

[0248] Optionally, the measurement configuration information may further include a reference signal to be measured, a frequency point to be measured, and a quantity to be measured. The frequency point to be measured refers to the frequency domain location information to be measured. The quantity to be measured may include at least one of the following: RSRP, RSRQ, SINR, PMI, CQI, RI.

[0249] Optionally, the measurement configuration information may further include a preset rule, which is used by the terminal device to select the measurement result to be reported. The preset rule may include at least one of the following: selecting the measurement result of the candidate cell based on signal strength; selecting the measurement result of the reference signal set based on signal strength; selecting the measurement result of the reference signal based on signal strength; selecting the measurement result based on the measurement result of the special cell; and selecting the measurement result based on the measurement result of the reference signal received power (RSRP).

[0250] It should be noted that other specific contents of this step can be referred to S410 and will not be described in detail here.

[0251] S520: The MAC layer of the terminal device determines that an event triggering condition is met based on the measurement configuration information.

[0252] In some embodiments, S520 may specifically include: a MAC layer of the terminal device measures a reference signal to be measured, and determines that an event triggering condition is met.

[0253] Specifically, the MAC layer of the terminal device can measure the reference signal to be measured and determine whether the measurement result of the reference signal to be measured (such as the first measurement result mentioned above) meets the event trigger condition. If it is determined that the event trigger condition is met, the MAC layer of the terminal device is in a reporting trigger state and executes S530.

[0254] In other embodiments, S520 may specifically include: the PHY layer of the terminal device measuring the reference signal to be measured and sending the measurement result to the MAC layer. The MAC layer may determine whether the measurement result of the reference signal to be measured meets the event triggering condition, that is, the MAC determines whether the event is met / triggered. If it is determined that the event triggering condition is met, the MAC layer of the terminal device enters a reporting triggering state and executes S530.

[0255] In some embodiments, the MAC layer determines that the measurement result of the reference signal to be measured meets the event triggering condition, the MAC layer is in a reporting triggering state, and a periodic reporting timer can be started; when the periodic reporting timer times out, the MAC layer is triggered to report and the periodic reporting timer is restarted, and the measurement result is sent through MAC layer signaling.

[0256] In some embodiments, when the MAC layer determines that the measurement result of the reference signal to be measured meets the event triggering condition, the periodic reporting timer is started; if the MAC layer determines that the event triggering condition is not met, the periodic reporting timer is stopped.

[0257] In some embodiments, the MAC layer of the terminal device may periodically determine whether an event is triggered (e.g., once every 5 ms), i.e., the MAC layer may periodically determine whether the measurement result of the reference signal to be measured meets the event triggering condition. Alternatively, the terminal device may determine whether an event is triggered within each preset time period (e.g., once within each 5 ms time period), i.e., the MAC layer may determine whether the measurement result of the reference signal to be measured meets the event triggering condition within a preset time period.

[0258] It should be understood that other contents in this step similar to those in the communication method 400 can be referred to S420 and S430 and will not be repeated here.

[0259] S530: The terminal device sends the measurement result to the network device via MAC layer signaling. Correspondingly, the network device receives the measurement result.

[0260] In some embodiments, after the measurement result is sent to the network device via MAC layer signaling, the MAC layer reporting trigger is canceled.

[0261] In some embodiments, the MAC layer signaling may include a medium access control layer control element MAC CE, or other control signaling, for example, MAC layer control signaling that may appear in future network systems.

[0262] It should be understood that when uplink resources are available, the terminal device can generate a MAC CE; the terminal device can send a MAC CE to the network device via MAC layer signaling, and the MAC CE carries the measurement result (such as the second measurement result described above). Furthermore, after the terminal device sends the MAC CE, the MAC layer can cancel the triggering report. If subsequent measurement result reporting is required, the MAC layer must wait for the next reporting process to be triggered, for example, when the periodic reporting timer described above expires.

[0263] The content included in the MAC CE may refer to S430.

[0264] In some embodiments, the PHY layer measures the first reference signal and the second reference signal, determines that both the first reference signal and the second reference signal meet an event triggering condition, and sends first indication information to the MAC layer. The MAC layer sends the measurement result corresponding to the first reference signal to the network device via first MAC layer signaling based on the first indication information and a preset rule. Furthermore, the measurement result corresponding to the second reference signal may also be sent to the network device via second MAC layer signaling.

[0265] If uplink resources are insufficient, the measurement results corresponding to the first reference signal and the measurement results corresponding to the second reference signal cannot be sent simultaneously through the first MAC layer signaling. In this case, the MAC layer can filter based on preset rules and select the measurement results corresponding to the first reference signal that meet the preset rules, so that the first MAC layer signaling gives priority to sending the measurement results corresponding to the first reference signal.

[0266] In some embodiments, when there is no available uplink resource for sending MAC layer signaling, the terminal device may send a scheduling request SR message to the network device, where the scheduling request message is used to request uplink resources for sending measurement results. Correspondingly, the network device receives the scheduling request message.

[0267] In some embodiments, a terminal device may receive a first scheduling request configuration and a second scheduling request configuration sent by a network device; when the data volume of the measurement result is greater than or equal to a first preset value, the terminal device may select the first scheduling request configuration to send the scheduling request information; when the data volume of the measurement result is less than the first preset value, the terminal device may select the second scheduling request configuration to send the scheduling request information. Correspondingly, the network device may send the first scheduling request configuration and the second scheduling request configuration to the terminal device, where the first scheduling request configuration is used when the data volume of the measurement result reported by the terminal device is greater than or equal to the first preset value, and the second scheduling request configuration is used when the data volume of the measurement result reported by the terminal device is less than the first preset value.

[0268] It should be understood that other contents in this step similar to those in the communication method 400 can be referred to S430 and will not be repeated here.

[0269] In this embodiment, the PHY layer or MAC layer of the terminal device can measure the reference signal to be measured, and the MAC layer determines that the measurement result obtained by the measurement meets the event trigger condition. If the event trigger condition is met, the MAC layer can be in a reporting trigger state, and then the terminal device can send the measurement result through MAC layer signaling (such as MAC CE). The network device can receive the measurement result and can update the scheduling strategy or perform mobility management such as cell switching and beam switching based on the measurement result.

[0270] It should be understood that MAC layer signaling (such as MAC CE), which is L2 signaling, is generated and sent faster than L3 signaling. In addition, the measurement result is reported only when the measurement result meets the event triggering condition; when the measurement result does not meet the event triggering condition, the measurement result is not reported, thereby reducing uplink resource occupancy. In other words, the present application determines the event triggering through the MAC layer and sends the measurement result through MAC layer signaling. When the event is triggered and uplink resources are available, the terminal device can quickly and timely report the measurement result, and can also reduce the uplink resource occupancy of the terminal device.

[0271] FIG7 is a schematic flow chart of another communication method 600 provided in an embodiment of the present application. It should be noted that the difference between the communication method 600 and the communication method 400 is that the communication method 600 measures the reference signal to be measured through the PHY layer and reports the measurement result through the PHY layer, while the communication method 400 measures the reference signal to be measured through the PHY layer and reports the measurement result through the MAC layer. Therefore, some contents in the communication method 500 may refer to the communication method 400.

[0272] As shown in FIG7 , the communication method 600 includes at least the following steps.

[0273] S610: The network device sends measurement configuration information to the terminal device. Correspondingly, the terminal device receives the measurement configuration information.

[0274] The measurement configuration information may include an event triggering condition, and the event triggering condition may be understood as a preset condition that a measurement result of a certain measurement quantity must satisfy.

[0275] Optionally, the measurement configuration information may further include a reference signal to be measured, a frequency point to be measured, and a quantity to be measured. The frequency point to be measured refers to the frequency domain location information to be measured. The quantity to be measured may include at least one of the following: RSRP, RSRQ, SINR, PMI, CQI, RI.

[0276] Optionally, the measurement configuration information may further include a preset rule, which is used by the terminal device to select the measurement result to be reported. The preset rule may include at least one of the following: selecting the measurement result of the candidate cell based on signal strength; selecting the measurement result of the reference signal set based on signal strength; selecting the measurement result of the reference signal based on signal strength; selecting the measurement result based on the measurement result of the special cell; and selecting the measurement result based on the measurement result of the reference signal received power (RSRP).

[0277] It should be noted that other specific contents of this step can be referred to S410 and will not be described in detail here.

[0278] S620: The PHY layer of the terminal device measures the reference signal to be measured and determines whether the event triggering condition is met.

[0279] Specifically, the PHY layer (i.e., L1 layer) of the terminal device can measure the reference signal to be measured and determine whether the measurement result of the reference signal to be measured (such as the first measurement result mentioned above) meets the event trigger condition. If it is determined that the event trigger condition is met, the terminal device can execute S530.

[0280] It should be understood that the specific content of this step can be referred to S420 and will not be repeated here.

[0281] S630: The terminal device sends the measurement result to the network device via PHY layer signaling. Correspondingly, the network device receives the measurement result.

[0282] In this step, the measurement result may be reported to the network device via PHY layer signaling (such as uplink control information UCI), wherein the UCI may be carried on the PUCCH or the PUSCH.

[0283] In some embodiments, the terminal device uses PUCCH to send UCI, and the UCI can carry measurement results. In addition to the measurement results of the quantity to be measured, the measurement results can also indicate at least one of the following information: the event-triggered cell identifier, the event-triggered reference signal set identifier, and the event-triggered reference signal / beam identifier.

[0284] In other embodiments, the terminal device transmits UCI using the PUSCH, which may carry measurement results. When an event is triggered, the terminal device may use the most recently available PUSCH resource, multiplex the UCI onto that PUSCH resource, and transmit the UCI to the network device. The network device can then obtain the measurement results from the UCI.

[0285] In this embodiment, the PHY layer of the terminal device can measure the reference signal to be measured. If it is determined that the measurement result obtained by the measurement meets the event triggering condition, the terminal device can send the measurement result through PHY layer signaling (such as UCI). The network device can receive the measurement result and can update the scheduling strategy or perform mobility management such as cell switching and beam switching based on the measurement result.

[0286] It should be understood that the present application can determine whether an event is triggered through the PHY layer. When the event is triggered and there are uplink resources, the terminal device can quickly and timely report the measurement results, and can also reduce the uplink resource occupancy of the terminal device.
