Description

Technical Field

[0001] 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

[0002] In a mobile communication system, a terminal device can report the reference signal measurement results of the current serving cell and neighboring cells to the network device. The measurement results reported by the terminal device are very important for the network device to manage the terminal device. For example, when the measurement results show that the channel quality of the current serving cell is better, the network device can schedule more data packets and update the scheduling strategy; when the measurement results show that the channel quality of a neighboring cell is better than the current serving cell, the network device can instruct the terminal device to perform mobility management processes such as cell switching and beam switching.

[0003] However, when the terminal device reports the measurement results, it will also occupy uplink transmission resources. How to efficiently report the measurements is worth studying. Summary of the invention

[0004] The present application provides a communication method and a communication device, which can reduce the uplink resource occupancy of a terminal device while reporting measurement results quickly and timely.

[0005] In a first aspect, a communication method is provided, which is executed by a terminal device. The terminal device here may refer to the terminal device itself, or may refer to a processor, module, chip, or chip system in the terminal device that implements the method, and the method comprises: receiving measurement configuration information from a network device, the measurement configuration information comprising an event trigger condition; a physical PHY layer measures a reference signal to be measured, determines that the event trigger condition is met, and sends a first indication information to a medium access control MAC layer; and the MAC layer sends the measurement result to the network device through MAC layer signaling according to the first indication information.

[0006] 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) according to 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 the MAC layer signaling. When the event is triggered and there are uplink resources, the terminal device can quickly and timely report the measurement result. In addition, it can also reduce the uplink resource occupancy of the terminal device.

[0007] In combination with the first aspect, in certain implementations of the first aspect, the MAC layer sends the measurement result to the network device via 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 via the MAC layer signaling.

[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 the first indication information to the MAC layer, thereby triggering the MAC layer to report, and then the terminal device can send the measurement result through the MAC layer signaling. In other words, the MAC layer can enter the reporting trigger state, and when the MAC layer is in the reporting trigger state, the measurement result can be sent through the MAC layer signaling.

[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: 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 result through the MAC layer signaling.

[0010] In this implementation, if the PHY layer determines that the measurement result of the reference signal to be measured always meets the event triggering condition, the PHY layer does not need to send the first indication information to the MAC layer multiple times. The MAC layer can start the periodic reporting timer after receiving the first indication information for the first time, and when the periodic reporting timer times out, it can still trigger the MAC layer to report and restart the periodic reporting timer, and send the measurement result through the MAC layer signaling. This can avoid repeatedly sending the first indication information and reduce the complexity of the interaction between layers.

[0011] 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 reporting trigger of the MAC layer.

[0012] In this implementation, if the MAC layer reports the measurement result through the MAC layer signaling, the reporting trigger of the MAC layer can be canceled, that is, the reporting trigger state of the MAC layer can be canceled to avoid being in the triggered state all the time, resulting in continuous use of 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 times out.

[0013] 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 second indication information to the MAC layer; and the MAC layer stops the periodic reporting timer based on the second indication information.

[0014] In this implementation, if the MAC layer receives the first indication information sent by the PHY layer, the periodic reporting timer can be started; 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.

[0015] In combination with the first aspect, in some 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 a future network system.

[0016] 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.

[0017] 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 medium 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 a preset rule.

[0018] 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 through MAC layer signaling. In this case, the MAC layer can screen 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 gives priority to sending the measurement results corresponding to the first reference signal. This is conducive to timely reporting of the more important part of the measurement results.

[0019] 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 according to signal strength; selecting the measurement result of the reference signal set according to signal strength; selecting the measurement result of the reference signal according to signal strength; selecting the measurement result according to the measurement result of the special cell; selecting the measurement result according to the measurement result of the reference signal received power RSRP.

[0020] 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 configure different priorities of candidate cells / reference signal sets / reference signals, and 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 enters it into the MAC CE.

[0021] 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.

[0022] 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 scheduling request SR information to the network device, wherein the scheduling request information is used to request uplink resources for sending the measurement results.

[0023] In this implementation, if the terminal device has no uplink resources to send MAC layer signaling, it can send scheduling request information to the network device to request 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 SR and can instruct the PHY layer to send PUCCH SR.

[0024] 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.

[0025] 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 MACCE, and avoid the problem of excessive waste of uplink resources.

[0026] 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.

[0027] 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 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.

[0028] 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 / special 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 measurement result of a beam in the secondary cell by a preset threshold.

[0029] The event triggering conditions at the reference signal set level may include any of the following: the measurement result of the reference signal set corresponding to the service cell is higher than the preset threshold; the measurement result of the reference signal set corresponding to the service 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 service 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 service 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 measurement result of the reference signal set corresponding to the secondary cell by a preset threshold.

[0030] It should be noted that in the implementation of the first aspect, the reference signal is measured by the PHY layer to determine 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 the MAC layer can be instructed to report. In some other implementations except the implementation of the first aspect, the reference signal can also be measured by the PHY layer, and the MAC layer can determine whether the event trigger condition is met. If the event trigger condition is met, the report is made. Alternatively, the reference signal can also be measured by the MAC layer, and the event trigger condition can be determined. If the event trigger condition is met, the report is made through the MAC layer. Alternatively, the reference signal can also be measured by the PHY layer, and the event trigger condition can be determined. If the event trigger condition is met, the report is made through the PHY layer. Specifically:

[0031] In some possible implementations, the communication method may include: a terminal device receives measurement configuration information sent by a network device, the measurement configuration information includes an event triggering condition; a PHY layer of the terminal device measures a reference signal to be measured, and sends the measurement result obtained by the measurement to a MAC layer, and 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 layer determines whether the event is met / triggered.

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., home evolved NodeB, or homeNode 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 can also be 5G, such as a next generation base station (next generation NodeB, gNB) in an NR system, or one or a group of (including multiple antenna panels) antenna panels of a base station in a 5G system, or a network node constituting a gNB, such as a baseband unit (BBU), or 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.

[0090] In some deployments, the gNB may include a CU and a DU. For example, the CU implements some functions of the gNB, and the DU implements some functions of the gNB, for example, the CU is responsible for processing non-real-time protocols and services, and implements the functions of the radio resource control (RRC) layer and the packet data convergence protocol (PDCP) layer; the DU may include the functions of the radio link control (RLC) layer, the functions of the media access control (MAC) layer, and some functions of the physical (PHY) layer.

[0091] The network equipment provides services for the cell, and the terminal equipment communicates with the cell through the transmission resources (for example, frequency domain resources, or spectrum resources) allocated by the network equipment. The cell can belong to a macro base station (for example, macro eNB or macro gNB, etc.), or it can belong to a base station corresponding to a small cell. The small cell here may include: metro cell, micro cell, pico cell, femto cell, etc. These small cells have the characteristics of small coverage and low transmission power, and are suitable for providing high-speed data transmission services.

[0092] 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.

[0093] The terminal device may be a device that provides voice / data connectivity to the user, for example, a handheld device with wireless connection function, a vehicle-mounted device, etc. At present, some examples of terminal devices may be: mobile phones, tablet computers, computers with wireless transceiver functions (such as laptops, PDAs, etc.), mobile Internet devices (mobile internet devices, MIDs), virtual reality (virtual reality, VR) devices, augmented reality (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 (session initiation protocol, SIP) phones, wireless local loop (wireless local loop, WLL) stations, personal digital assistants (personal digital assistants, PDAs), handheld devices with wireless communication functions, 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 communication networks (publicland mobile networks, PLMNs), etc.

[0094] Among them, wearable devices can also be called wearable smart devices, which are a general term for the intelligent design and development of wearable devices for daily wear using wearable technology, 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 clothes or accessories. Wearable devices are not only hardware devices, but also realize powerful functions through software support, data interaction, and cloud interaction. Broadly speaking, wearable smart devices include full-featured, large-sized, and independent of smartphones to achieve complete or partial functions, 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.

[0095] In addition, the terminal device can also be a terminal device in the Internet of Things (IoT) system. IoT is an important part of the future development of information technology. Its main technical feature is to connect objects to the network through communication technology, thereby realizing an intelligent network of human-machine interconnection and object-to-object interconnection. IoT technology can achieve massive connections, deep coverage, and terminal power saving through narrowband (NB) technology, for example.

[0096] 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 equipment), receiving control information and downlink data from network devices, and sending electromagnetic waves to transmit uplink data to network devices.

[0097] In order to better understand the communication method provided in the embodiments of the present application, the terms involved in the present application are first briefly explained.

[0098] (1) Cell, serving cell, candidate cell

[0099] A cell is described at a high level from the perspective of resource management, mobility management, or service unit. The coverage of each network device can be divided into one or more cells, and each cell can correspond to one or more frequency points, or in other words, each cell can be regarded as an area formed by the coverage of one or more frequency points. It should be noted that a cell can be an area within the coverage of a wireless network of a network device.

[0100] The serving cell is the cell where the terminal device currently resides. 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.

[0101] (2) Special cell (SpCell) and secondary cell (SCell)

[0102] Figure 1 This is a schematic diagram of the relationship between SpCell and SCell provided in the embodiment of the present application. Figure 1 Describe the concepts of SpCell and SCell in detail.

[0103] The terminal device can communicate with one or more cells. When the terminal device communicates with a single cell, the cell can be called SpCell; when the 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 the terminal device communicates with multiple cells through CA, the multiple cells are divided into primary cells (PCell) and SCell, among which PCell can be called SpCell. In the CA scenario, SpCell can be PCell.

[0104] When a terminal device communicates with multiple cells via DC, such as Figure 1 As shown, there are a master cell group (MCG) and a secondary cell group (SCG). The MCG may include multiple cells, among which the cell used to initiate the initial access is called PCell, which can also be understood as the cell that is the general commander among multiple cells is called PCell, and the rest are called SCell. The PCell and SCell in the MCG are combined together through the CA technology. Similarly, the SCG may also include multiple cells, among which the cell used to initiate the initial access is called primary secondary cell (PSCell), which can also be understood as the cell that is the general commander among multiple cells of the SCG is called PSCell, and the rest are called SCell. 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 the 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.

[0105] (3) Reference signal

[0106] The reference signal can be used for channel measurement, channel estimation or beam quality monitoring, etc. The reference signal involved in the embodiments of the present application may include, for example, a channel state information reference signal (CSI-RS) and a synchronization signal physical broadcast channel block (SSB).

[0107] To facilitate understanding of the embodiments of the present application, Figure 2 A communication system applicable to an embodiment of the present application is described in detail. Figure 2 1 is a schematic diagram of the network architecture of the communication system 100 provided in the embodiment of the present application. Figure 2 As shown, the communication system 100 may include a network device and a terminal device. 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 serving the terminal device, the terminal device may operate in a CA or DC or coordinated multiple points transmission / reception (CoMP) mode, and at least one cell may provide the terminal device with more than one wireless resource corresponding to a transmission parameter set.

[0108] For example, Figure 2 As shown in , the terminal device 110 is simultaneously located in the cell of the network device 120, the cell of the network device 130, and the cell of the network device 140. The network device 120 may be a macro base station (such as macroeNB), and the network devices 130 and 140 may be micro base stations (such as smalleNB). It should be understood that Figure 2 This is only a schematic diagram. The communication system 100 may also include other network devices such as core network equipment, wireless relay equipment, and wireless backhaul equipment. Figure 2 Not shown.

[0109] 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.

[0110] 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 may correspond to network devices in 5G (such as gNB or ng-eNB), and in a 4G system, they may correspond to network devices in 4G (such as eNB or en-gNB).

[0111] The network devices and terminal devices in the embodiments of the present application can be deployed on land, including indoors or outdoors, handheld or vehicle-mounted; can also be deployed on the water surface; can also be deployed on aircraft, balloons and artificial satellites in the air. The embodiments of the present application do not limit the application scenarios of the network devices and terminal devices.

[0112] 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.

[0113] In a mobile communication system, a terminal device (such as a UE) can report the reference signal measurement results of the current serving cell and neighboring cells to a network device (such as a gNB). The measurement results reported by the UE are very important for the base station to manage the UE. For example, when the measurement results show that the channel quality of the current serving cell is good, the gNB can schedule more data packets and update the scheduling strategy; when the measurement results show 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 processes such as cell switching and beam switching.

[0114] However, when UE reports measurement results, uplink transmission resources will also be occupied. How to efficiently perform measurement reporting is worth studying.

[0115] Figure 3 A schematic flow chart of a method 200 for reporting measurement results is shown. The method 200 mainly involves an L1 measurement reporting mechanism, wherein L1 refers to a physical layer, and the process of reporting the L1 measurement results is mainly completed by the physical layer.

[0116] S210, the gNB sends L1 measurement configuration information to the UE. Correspondingly, the UE receives the L1 measurement configuration information.

[0117] 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 amount, and an uplink resource used for reporting.

[0118] 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.

[0119] The reporting mode may include periodic reporting, non-periodic reporting or semi-static reporting. Among them, periodic reporting means that the UE performs periodic reporting according to the period configured by the gNB. Non-periodic reporting means that the gNB sends an indication signaling to trigger the UE to report once. Semi-static reporting means that the gNB sends an indication signaling to trigger the UE to start periodic reporting thereafter.

[0120] 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 results 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 results 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.

[0121] 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.

[0122] S220: The UE measures the reference signal to be measured according to the L1 measurement configuration information to obtain an L1 measurement result.

[0123] In this step, the UE can measure the reference signal to be measured according to the L1 measurement configuration information configured by the gNB to obtain the L1 measurement result. The reference signal to be measured and the measurement quantity to be measured are both configured by the gNB, that is, the UE can obtain the reference signal set to be measured and the reported measurement quantity from the L1 measurement configuration information.

[0124] S230, the gNB sends an indication signaling to the UE. Correspondingly, the UE receives the indication signaling sent by the gNB

[0125] It should be understood that this step is an optional step.

[0126] When the gNB instructs the UE to use the aperiodic reporting mode or the semi-static reporting mode, the gNB needs to send an indication signaling to the UE, which is used to indicate whether the UE uses the aperiodic reporting mode or the semi-static reporting mode. When the gNB instructs the UE to use the periodic reporting mode, the gNB may not need to send an indication signaling to the UE.

[0127] S240, the UE reports the L1 measurement result according to the L1 measurement configuration information. Correspondingly, the gNB receives the L1 measurement result.

[0128] In this step, the UE can report the L1 measurement result according to the L1 measurement configuration information configured by the gNB. That is, the UE can obtain the reporting mode and the uplink resources used for reporting from the L1 measurement configuration information. When reporting the L1 measurement result, the UE can report the L1 measurement result according to the reporting mode and the uplink resources used configured by the gNB.

[0129] For example, the L1 measurement result may be reported to the gNB via L1 uplink control information (UCI), where the UCI may be carried on the PUCCH or PUSCH. The above measurement result is referred to as the L1 measurement result, i.e., the measurement result obtained by the physical layer (L1 layer) of the UE measuring the received reference signal.

[0130] In the above L1 measurement reporting mechanism, the UE uses more uplink resources for reporting, and the UE consumes more power. For example, when the periodic reporting mode is configured, the gNB needs to provide periodic PUCCH resources. Even if the channel conditions of the UE do not change significantly, it needs to continue to occupy these periodic PUCCH resources and continue to report, wasting uplink resources and consuming UE power.

[0131] Figure 4 A schematic flow chart of another method 300 for reporting measurement results is shown. The method 300 mainly involves an L3 measurement reporting mechanism, wherein L3 refers to a radio resource control (RRC) layer, and the process of reporting L3 measurement results needs to be completed via the RRC layer.

[0132] S310, the gNB provides L3 measurement configuration information to the UE. Correspondingly, the UE receives the L3 measurement configuration information.

[0133] The L3 measurement configuration information may include at least one of the following: a frequency point to be measured, a reference signal set to be measured, a reporting method, and a reported measurement amount.

[0134] The frequency point to be measured refers to the frequency domain position 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.

[0135] The reporting methods include periodic reporting and event-triggered reporting. Among them, periodic reporting means that the UE reports periodically according to the period configured by the gNB. Event-triggered reporting means that the gNB can configure some events for the UE, and when the UE determines that the event is triggered (or the conditions of the event are met), it reports. Among them, the events configured by the gNB for the UE may include the following:

[0136] Event A1: The measurement result of the serving cell is higher than the preset threshold.

[0137] Event A2: The measurement result of the serving cell is lower than the preset threshold.

[0138] Event A3: The measurement result of the neighboring cell is higher than the measurement result of the serving cell (or special cell SpCell) than the preset threshold.

[0139] Event A4: The measurement result of the neighboring cell is higher than the preset threshold.

[0140] 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.

[0141] Event A6: The measurement result of the neighboring cell is higher than the measurement result of the secondary cell by a preset threshold.

[0142] 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.

[0143] It should be noted that the measurement result by which the above events are triggered can be specified by the gNB, that is, the gNB specifies whether the condition for the UE to determine the event triggering is the RSRP measurement result, the RSRQ measurement result, or the SINR measurement result.

[0144] The reported measurement quantity may include at least one of the following: RSRP, RSRQ, SINR, PMI, CQI, and RI.

[0145] S320: The UE measures the reference signal to be measured according to the L3 measurement configuration information to obtain an L3 measurement result.

[0146] In this step, the UE can measure the reference signal to be measured according to the L3 measurement configuration information configured by the gNB to obtain the L3 measurement result. Among them, the frequency point to be measured, the reference signal to be measured and the measurement amount to be measured are all configured by the gNB, that is, the UE can obtain the frequency point to be measured, the reference signal set to be measured and the reported measurement amount from the L3 measurement configuration information.

[0147] S330, the UE reports the L3 measurement result according to the L3 measurement configuration information. Correspondingly, the gNB receives the L3 measurement result.

[0148] In this step, the UE can report the L3 measurement result according to the L3 measurement configuration information configured by the gNB. That is, the UE can obtain the reporting method from the L3 measurement configuration information, and when reporting the L3 measurement result, the UE can report the L3 measurement result according to the reporting method configured by the gNB.

[0149] It should be understood that the L3 measurement result is reported to the gNB via an RRC message. Specifically, the L3 measurement result of the UE needs to be filtered by the RRC layer and reported via an RRC message.

[0150] 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, resulting in the measurement results arriving at the gNB later, and there is a problem of untimely reporting.

[0151] In view of the above-mentioned L1 and L3 measurement reporting mechanism, the present application provides a communication method and a communication device, which designs an event-triggered reporting mechanism, thereby reducing the uplink resource occupancy of the UE and reducing the reporting power consumption of the UE while reporting the measurement results quickly and timely.

[0152] Figure 5 4 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, where the terminal device 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 the present application does not limit this.

[0153] S410, the terminal device receives the measurement configuration information sent by the network device. Correspondingly, the network device sends the measurement configuration information to the terminal device.

[0154] 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.

[0155] 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.

[0156] Specifically, the cell-level event triggering conditions may include any of the following: the measurement result of the serving cell is higher than a preset threshold; the measurement result of the serving cell is lower than a preset threshold; the measurement result of the neighboring cell is higher than the preset threshold than the measurement result of the serving cell / special cell; the measurement result of the neighboring cell 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 cell is higher than the threshold; the measurement result of the neighboring cell is higher than the measurement result of the secondary cell by a preset threshold.

[0157] 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 / special 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 measurement result of a beam in the secondary cell by a preset threshold.

[0158] The event triggering conditions at the reference signal set level may include any of the following: the measurement result of the reference signal set corresponding to the service cell is higher than the preset threshold; the measurement result of the reference signal set corresponding to the service 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 service 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 service 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 measurement result of the reference signal set corresponding to the secondary cell by a preset threshold.

[0159] 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, and 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).

[0160] The cell-level triggering event (A event) may refer to S310, and the A event may include A1 event to A6 event. For example, when the RSRP of each beam in the measurement result of the beam of the serving cell is less than a preset threshold, the terminal device reports the measurement result to the network device.

[0161] Beam-level trigger events (X events) may include the following:

[0162] Event X1: The measurement result of the beam being used by the serving cell is higher than the preset threshold.

[0163] Event X2: The measurement result of the beam being used by the serving cell is lower than the preset threshold.

[0164] 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) than the preset threshold.

[0165] Event X4: The measurement result of a beam in the neighboring area is higher than the preset threshold.

[0166] 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.

[0167] 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.

[0168] The trigger events (Y events) at the reference signal set level may include the following:

[0169] Event Y1: The measurement result of the reference signal set of the corresponding serving cell is higher than the preset threshold.

[0170] Event Y2: The measurement result of the reference signal set of the corresponding serving cell is lower than the preset threshold.

[0171] 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) than the preset threshold.

[0172] Event Y4: The measurement result of the reference signal set of the corresponding neighboring cell is higher than the preset threshold.

[0173] 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.

[0174] 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.

[0175] It should be understood that there may be other event contents. This application does not limit the specific event contents, and the above event contents are only for illustrative purposes.

[0176] It should be noted that the embodiments of the present application do not limit the size 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 can be considered that the cell-level measurement result of a 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 can be considered that 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 / special cell. In some embodiments, when the preset threshold is 0, it can 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.

[0177] It should be noted that the above measurement results are specified by the network device as the measurement results of which measurement quantity, for example, RSRP measurement results, RSRQ measurement results, SINR measurement results, etc. Exemplarily, when the RSRP of each beam in the measurement results of the beams of the serving cell is less than a preset threshold, the terminal device reports the measurement results corresponding to the reference signal to the network device.

[0178] It is understandable that the event triggering condition implicitly includes the triggering event granularity and the triggering event type.

[0179] 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.

[0180] UE-level granularity: Use a unified event for the UE. Specifically, the network device will assign an event (such as A1 event) to the UE, that is, whether evaluating different reference signal sets or evaluating different cells, when the measurement result of the serving cell (such as the RSRP measurement result) is higher than the 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 of the serving cell.

[0181] Cell-level granularity: Different events can be configured for different neighboring cells / candidate cells. Specifically, for candidate cell 1, the network device will assign an 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 threshold values ​​of event A1. For example, event 1 is that the measurement result of the serving cell is higher than threshold value x, and event 2 is that the measurement result of the serving cell is higher than threshold value y.

[0182] Granularity at the reference signal set level: 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 events corresponding to different reference signal sets are different. For example, for reference signal set 1, when the measurement result of the neighboring cell is higher than the measurement result of the serving cell by x, it is reported; for reference signal set 2, when the signal quality of the neighboring cell is higher than the signal quality of the serving cell by y, it is reported, so as to enable more refined control.

[0183] Beam-level granularity / reference signal-level granularity: Different events can be configured for different beams to be tested / reference signals to be tested. Specifically, network equipment can assign different events to different beams to be tested / reference signals to be tested. For example, for beam 1 / reference signal 1, a report is made when the measurement result of the neighboring cell is x higher than the measurement result of the serving cell; for beam 2 / reference signal 2, a report is made when the signal quality of the neighboring cell is y higher than the signal quality of the serving cell, thereby enabling more refined control.

[0184] 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, and an event of an aggregate-level measurement result.

[0185] An event of a cell-level measurement result, for example, a cell-level measurement result of a neighboring cell / candidate cell is higher than a cell-level measurement result of a current serving cell, or higher than a preset threshold. Exemplarily, the cell-level measurement result may be an average of measurement results of multiple reference signals of the cell.

[0186] An event of a beam-level measurement result, for example, the beam-level measurement result of a neighboring cell / candidate cell is higher than the beam-level measurement result of the beam currently being used by the serving cell, or higher than a preset threshold. A beam-level measurement result generally refers to the measurement result of a reference signal, that is, a reference signal corresponds to a beam direction.

[0187] An event of set-level measurement results, such as the average measurement result of multiple reference signals in a reference signal set is higher than the measurement result of the beam / reference signal currently being used by the serving cell, or higher than a preset threshold. Another example is 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 being used by the serving cell, or higher than a preset threshold.

[0188] Optionally, the measurement configuration information may also 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 position information to be measured. The report quantity to be measured may include at least one of the following: RSRP, RSRQ, SINR, PMI, CQI, RI.

[0189] The reference signals to be tested include the reference signals of the serving cell and / or the reference signals of the neighboring cells. In the scenario of mobility management, the neighboring cells may also be referred to as candidate cells, to which the UE may later switch, that is, the candidate cell is regarded as the target cell for switching, and the target cell becomes the new serving cell of the UE. The reference signals to be tested may be SSB, CSI-RS or other types of reference signals, and different reference signals correspond to different beam directions.

[0190] It should be understood that the reference signal to be measured may be a set of one or more reference signals, and the set of reference signals 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 be distinguished by the identifier of the reference signal (such as the ID of the reference signal). That is, the measurement configuration information may include a set of one or more reference signals, and each set of reference signals may include the identifier of the reference signal of the serving cell and / or the neighboring cell.

[0191] 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 according to the signal strength; selecting the measurement result of the reference signal set according to the signal strength; selecting the measurement result of the reference signal according to the signal strength; selecting the measurement result according to the measurement result of the special cell; selecting the measurement result according to the measurement result of the reference signal received power RSRP.

[0192] It should be noted that the content of the above events (including event granularity and event type) can be generated by the gNB that manages the current serving cell (i.e., serving gNB) or by the gNB that manages the neighboring cell / candidate cell (i.e., neighboring gNB or candidate gNB). If generated by the neighboring gNB / candidate gNB, the neighboring gNB / candidate gNB sends the event content to the serving gNB, which then sends it to the UE.

[0193] 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.

[0194] 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 a first indication message to the MAC layer, and the first indication message 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, when the MAC layer receives the first indication message, the MAC layer triggers reporting, or enters a triggered reporting state, and then the MAC layer can send a second measurement result to the network device.

[0195] 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 amount, and the second measurement result is the measurement result corresponding to the second measurement amount. It should be understood that the first measurement amount and the second measurement amount are both specified by the network device. Specifically, the terminal device can obtain the first measurement amount and the second measurement amount from the measurement configuration information. Among them, the first measurement amount 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 amount 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.

[0196] For example, the first measurement result is a measurement result of RSRQ, and the reported second measurement result is also a measurement result of RSRQ. For another example, the first measurement result is a measurement result of RSRP, but the reported second measurement result is a measurement result of PMI. For another example, the first measurement result is a measurement result of RSRP, and the reported second measurement result includes a measurement result of RSRP, a measurement result of PMI, a measurement result of CQI, and a measurement result of RI.

[0197] 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 the candidate cell to obtain beam-level measurement results.

[0198] Exemplarily, the reference signals of the serving cell are SSB 1, SSB 2, CSI-RS1, and CSI-RS2, the reference signals of the first candidate cell are SSB 1, SSB 2, CSI-RS1, and CSI-RS2, and the reference signals of the second candidate cell are SSB 1, SSB 2, CSI-RS1, and CSI-RS 2, wherein 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.

[0199] The above 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 results, it can further determine the reference signal set-level measurement results and the cell-level measurement results, and send the measurement results to the network device.

[0200] It should be understood that in the embodiment of the present application, in order to facilitate the distinction of measurement results of different granularities, the measurement results of the beam, the measurement results of the reference signal set, and the measurement results of the cell are respectively recorded as: beam-level measurement results, reference signal set-level measurement results, and cell-level measurement results. When describing the measurement results separately, the measurement results may include at least one of the beam-level measurement results, the reference signal set-level measurement results, and the cell-level measurement results. Among them, the beam-level measurement results may also be referred to as reference signal-level measurement results.

[0201] 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 by taking the first reference signal set as an example.

[0202] The first reference signal set may include multiple reference signals, and the measurement results corresponding to the first reference signal set are 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 results of the first reference signal set based on the beam-level measurement results. For example, the PHY layer of the terminal device may measure multiple reference signals (i.e., multiple beams) under the first reference signal set to determine the measurement results of a single beam, and then determine the measurement results of the first reference signal set based on the measurement results of the single beam.

[0203] S430, the MAC layer of the terminal device sends the measurement result to the network device through MAC layer signaling according to the first indication information. Correspondingly, the network device receives the measurement result.

[0204] 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 through the MAC layer signaling. Specifically, the PHY layer 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 the first indication information to the MAC layer, thereby triggering the MAC layer to report, and then the terminal device can send the measurement result through the MAC layer signaling. In other words, the MAC layer can enter the reporting trigger state, and when the MAC layer is in the reporting trigger state, the measurement result can be sent through the MAC layer signaling.

[0205] In some embodiments, when the MAC layer receives the first indication information, the periodic reporting timer is 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 the 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 result, if the PHY layer determines that the event is still in the 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.

[0206] In some embodiments, after the measurement result is sent to the network device via MAC layer signaling, the reporting trigger of the MAC layer is canceled. Specifically, if the MAC layer reports the measurement result via MAC layer signaling, the reporting trigger of the MAC layer can be canceled, that is, the reporting trigger state of the MAC layer can be canceled to avoid being in the triggered state all the time, resulting in continuous use of 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 times out.

[0207] 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 trigger 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.

[0208] In some embodiments, when the MAC layer receives the first indication information, it starts the periodic reporting timer; when the PHY layer determines that the event triggering condition is not met, it sends the second indication information to the MAC layer; the MAC layer stops the periodic reporting timer according to 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 the 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 according to the second indication information.

[0209] Optionally, after receiving the second indication information, the MAC layer may trigger the last reporting process again, 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.

[0210] Optionally, the PHY layer of the terminal device determines whether the measurement result (such as the first measurement result mentioned above) meets 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 mentioned above) meets the event triggering condition within each preset time period. Exemplarily, the PHY layer of the terminal device can 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).

[0211] In some embodiments, the MAC layer signaling may include a control unit MAC CE of a medium access control layer, or other control signaling, for example, control signaling of a MAC layer that may appear in a future network system.

[0212] 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). Further, 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 next reporting process to be triggered, for example, the above-mentioned periodic reporting timer times out, or the first indication information of the PHY layer is received.

[0213] 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 includes the measurement result of the RSRP of the reference signal 1 of the serving cell 1. In some possible solutions, the identifier of the serving cell may correspond to the identifier of a special cell.

[0214] In one example, the format of MAC CE may be as shown in Table 1. MAC CE may include an identifier of a candidate cell / serving cell / reference signal set (i.e., Candidate / Serving / Reference Signal Set ID), an identifier of a special cell reference signal (i.e., RS ID of the SpCell), and an L1 measurement result of a special cell (i.e., L1 result ofSpCell). Optionally, MAC CE may also include an identifier of a secondary cell (i.e., SCell ID), an identifier of a special cell reference signal (i.e., RS ID of the SCell), and a measurement result of a secondary cell (L1 result of SCell).

[0215] 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 specifically understood as the type of the reported measurement quantity (report quantity type), such as RSRP or RSRQ or SINR, or other measurement quantity types. The measurement result corresponding to the quantity to be measured is the measurement result (value of the report) corresponding to the above measurement quantity type.

[0216] 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.

[0217] Table 1

[0218]

[0219] 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.

[0220] Wherein, Ti refers to the i-th candidate cell (or the candidate cell identified as i) or the i-th reference signal set (or the reference signal set identified as i). When Ti is 1, it means that the candidate cell or the reference signal set meets the event triggering condition, or it can represent that the event corresponding to the candidate cell or the reference signal set is triggered; when Ti is 0, it means that the candidate cell or the reference signal set does not meet the event triggering condition, or it can represent that the event corresponding to the candidate cell or the reference signal set is not triggered. For other parameters, please refer to the explanation in Table 1.

[0221] Table 2

[0222]

[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 the event triggering condition, and sends the first indication information to the MAC layer; the MAC layer sends the measurement result corresponding to the first reference signal to the network device through the first MAC layer signaling according to the first indication information and the preset rule. In addition, the measurement result corresponding to the second reference signal can also be sent to the network device through the second MAC layer signaling.

[0224] The preset rule may include at least one of the following: selecting the measurement result of the candidate cell according to the signal strength; selecting the measurement result of the reference signal set according to the signal strength; selecting the measurement result of the reference signal according to the signal strength; selecting the measurement result according to the measurement result of the special cell; selecting the measurement result according to the measurement result of the 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] Exemplarily, when the terminal device has available uplink resources, the terminal device generates a MAC CE to send the measurement result. 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 reported by the terminal device for the measurement result has 10 bytes, the terminal device needs to truncate the MAC CE for reporting. 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] Exemplarily, 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 in the triggered event, and incorporates the selected measurement result into the MAC CE; if there is still space left for uplink resources, the terminal device can select the measurement result of the second strongest candidate cell or reference signal set to be incorporated into the MAC CE, and so on. When the uplink resources are insufficient to incorporate additional measurement results, the terminal device no longer selects measurement results to be incorporated into 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] Exemplarily, if there are multiple reference signals in the candidate cell or reference signal set corresponding to a certain triggered event, the terminal device selects the strongest X reference signals to be incorporated into the MAC CE, where X can be specified as 1, or specified as a special value, or can be configured by the network device. If the uplink resources can also incorporate additional measurement results, the terminal device selects the strongest X reference signals of the selected cell or reference signal set corresponding to another triggered event to be incorporated into the MAC CE, and so on. When the uplink resources are insufficient to incorporate additional measurement results, the terminal device no longer selects measurement results to be incorporated into the MAC CE, that is, 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 measurement result of SpCell to be incorporated into the MAC CE, but does not incorporate the measurement result of SCell into the MAC CE. Including the measurement result of SpCell into the MAC CE can be understood as MAC CE including the measurement result of SpCell.

[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 selects 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 selects SINR to be incorporated into the MAC CE, or selects 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 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 enters it into the MAC CE. 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.

[0236] If the uplink resources are insufficient, the measurement result corresponding to the first reference signal and the measurement result corresponding to the second reference signal cannot be sent simultaneously through the first MAC layer signaling. In this case, the MAC layer can screen based on preset rules and select the measurement result corresponding to the first reference signal that meets the preset rules, so that the first MAC layer signaling gives priority to sending the measurement result corresponding to the first reference signal. If there are uplink resources later, the measurement result corresponding to the second reference signal can 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 these 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, and the scheduling request message is used to request the uplink resource for sending the measurement result. 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 the SR and may instruct the PHY layer to send the PUCCH SR.

[0240] In some embodiments, the 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 first scheduling request configuration is selected to send the scheduling request information; when the data volume of the measurement result is less than the first preset value, the second scheduling request configuration is selected 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, the first scheduling request configuration being 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 being 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 may provide multiple sets of PUCCH SR configurations to the terminal device, and each set of PUCCH SR configurations may 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 (e.g., less than M), and the second set is used for a larger number of triggering events (e.g., greater than or equal to M). When the terminal device has less than M triggered events, the first set of PUCCH SR resources may be used. After the network device receives the PUCCH SR resources, it learns that the number of triggered events is less than M, and then it may 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 may be used. After the network device receives the PUCCH SR resources, it learns that the number of triggered events is greater than or equal to M, and then it may 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 the 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 It 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 the communication method 500 and the communication method 400 is that the communication method 500 measures the reference signal to be measured through the PHY layer or the MAC layer, and the MAC layer determines whether the event triggering condition is met, while the communication method 400 measures the reference signal to be measured through the PHY layer and determines whether the event triggering condition is met, so part of the content in the communication method 500 can refer to the communication method 400.

[0245] like Figure 6 As shown, the communication method 500 at least includes 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 also 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 position 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 for 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 according to the signal strength; selecting the measurement result of the reference signal set according to the signal strength; selecting the measurement result of the reference signal according to the signal strength; selecting the measurement result according to the measurement result of the special cell; selecting the measurement result according to 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 according to 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 some other embodiments, S520 may specifically include: the PHY layer of the terminal device measures the reference signal to be measured, and sends the measurement result obtained by the measurement to the MAC layer, and 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 is in 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 trigger condition, the MAC layer is in a reporting trigger state, and can start a periodic reporting timer; when the periodic reporting timer times out, the MAC layer reports and restarts the periodic reporting timer, and sends the measurement result 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 (for example, a determination is made every 5 ms), that is, 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 determines whether an event is triggered within each preset time period (for example, a determination is required within each 5 ms time period), that is, 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 refer 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 reporting trigger of the MAC layer is cancelled.

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

[0262] 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). Further, 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 times out.

[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 the event triggering condition, and sends the first indication information to the MAC layer; the MAC layer sends the measurement result corresponding to the first reference signal to the network device through the first MAC layer signaling according to the first indication information and the preset rule. In addition, the measurement result corresponding to the second reference signal can also be sent to the network device through the 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 screen 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 to send 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 an uplink resource for sending the measurement result. Correspondingly, the network device receives the scheduling request message.

[0267] In some embodiments, the 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 first scheduling request configuration is selected to send the scheduling request information; when the data volume of the measurement result is less than the first preset value, the second scheduling request configuration is selected 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, the first scheduling request configuration being 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 being 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 refer 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 an 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 will not be reported, thereby reducing the 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 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.

[0271] Figure 7 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] like Figure 7 As shown, 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 also 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 position 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 for 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 according to the signal strength; selecting the measurement result of the reference signal set according to the signal strength; selecting the measurement result of the reference signal according to the signal strength; selecting the measurement result according to the measurement result of the special cell; selecting the measurement result according to 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 an event triggering condition is met.

[0279] Specifically, the PHY layer (ie, 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: an event-triggered cell identifier, an event-triggered reference signal set identifier, and an event-triggered reference signal / beam identifier.

[0284] In some other embodiments, the terminal device uses PUSCH to send UCI, and the UCI can carry the measurement result. When the event is triggered, the terminal device can use the most recently available PUSCH resource, multiplex the UCI into the PUSCH resource, and send the UCI to the network device. The network device can obtain the measurement result 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), and 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.
