Description

Technical Field

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

[0002] Fifth-generation mobile networks (5G) introduce new radio (NR) bands to achieve wider bandwidth and higher transmission rates. However, due to the higher frequency, signals experience significant fading during propagation. Therefore, 5G NR employs beamforming (BF) technology to improve performance.

[0003] Furthermore, mobility management is a crucial component of wireless mobile communication, ensuring that the communication link between network devices and terminal devices is not interrupted due to the movement of terminal devices. In 5G NR, mobility management primarily involves inter-cell mobility and intra-cell mobility, with measurement and reporting being the main steps. Typically, the measurement and reporting process includes: the network device configuring measurement and reporting for the terminal device; the terminal device performing measurements on the corresponding configured resources according to the network device's measurement configuration; and after measurement, reporting to the network device according to the network device's reporting configuration so that handover between cells and within cells can be performed based on the measurement results.

[0004] Because the measurement and reporting procedures differ between inter-cell and intra-cell environments, the protocol stipulates that radio resource measurement (RRM) is used for inter-cell mobility management, while beam management (BM) is used for intra-cell mobility management.

[0005] In this system, the network device notifies the terminal device of the configuration information for RRM measurement and reporting through radio resource control (RRC) layer signaling. The reference signals for RRM measurement can include: reference signals of the serving cell and reference signals of non-serving cells; the types of reference signals can include: synchronization signal / physical broadcast channel block (SSB) and channel state information-reference signal (CSI-RS), etc.; the measured quantities can include: cell-level and beam-level parameters at the RRC layer (also called Layer 3), such as reference signal received power (RSRP), reference signal received quality (RSRQ), and signal interference noise radio (SINR), etc.; the configured cell may be a cell belonging to the same frequency, different frequency, or different system; the measurement results are reported by the terminal device after being encapsulated in RRC layer format and then reported to the network device.

[0006] In this process, the network device notifies the terminal device of the configuration information for measuring and reporting the beamforming (BM) via RRC layer (i.e., Layer 3) signaling and / or physical layer (also called Layer 1) signaling. The reference signal measured by the BM only includes the reference signal of the serving cell; the measured quantities can include: physical layer (i.e., Layer 1) beam level, such as reference signal receive power (RSRP), reference signal receive quality (RSRQ), and signal interference noise radio (SINR), etc.; the measurement results are reported by the terminal device to the network device through physical layer format encapsulation.

[0007] In summary, terminal devices cannot use beamforming (BM) to achieve inter-cell mobility management. Although terminal devices can use beamforming (RRM) to achieve inter-cell mobility management, the measurement result reporting delay of RRM is relatively large, making it impossible to achieve beam selection for fast inter-cell movement. Summary of the Invention

[0008] This application provides a communication method, apparatus, and device to realize inter-cell mobility management, and also reduces the mobility latency of terminal devices between cells, which is beneficial for beam selection for rapid inter-cell movement.

[0009] In a first aspect, this application provides a communication method, comprising: receiving a first message from a network device, the first message being used to instruct a terminal device to measure a reference signal of a first cell and configure the measurement result to be reported in a physical layer encoding format, the first cell including at least one non-serving cell of the terminal device, or the first cell including at least one serving cell and at least one non-serving cell of the terminal device; and obtaining a measurement result of the first cell based on the first message, the measurement result of the first cell being used by the terminal device to perform cell selection, cell reselection, or cell handover.

The first cell includes at least one non-serving cell of the terminal device, or the first cell includes at least one serving cell and at least one non-serving cell of the terminal device. Thus, not only can the terminal device be activated to measure the reference signal of the first cell, but by configuring the measurement results to be reported in a physical layer (Layer 1) encoding format, a foundation is laid for the terminal device to report the measurement results to the network device. This allows the terminal device to report the measurement results of the first cell in physical layer (Layer 1) encoding format to the network device in a timely and rapid manner. This not only achieves inter-cell mobility management but also reduces the inter-cell movement latency of the terminal device, facilitating beam selection for rapid inter-cell movement.

[0011] In one possible design of the first aspect, the method further includes: receiving a second message from a network device, the second message being used to instruct the terminal device to report the measurement results of the first cell to the network device, so that the terminal device can report the measurement results of the first cell based on the second message, which is simple and convenient; or, the first message being used to instruct the terminal device to report the measurement results of the first cell to the network device, so that the terminal device can report the measurement results of the first cell based on the first message, thereby saving configuration instructions.

[0012] In one possible design of the first aspect, the method further includes: processing the measurement results of the first cell into a physical layer encoding format based on the first message to obtain the measurement results of the first cell in physical layer encoding format; and reporting a third message to the network device, the third message including the measurement results of the first cell in physical layer encoding format.

[0016] In one possible design of the first aspect, the method further includes: receiving a fifth message from a network device, the fifth message indicating the maximum number of first cells that the terminal device measures based on the first message, and / or the cell set of the first cells, so that the terminal device can determine the cell range covered by the first cells.

[0020] The communication method provided in the second aspect involves a network device determining a first message. This first message not only instructs the terminal device to measure the reference signal of the first cell but also configures the measurement results to be reported in a physical layer (Layer 1) encoding format. The first cell includes at least one non-serving cell of the terminal device, or the first cell includes at least one serving cell and at least one non-serving cell of the terminal device. Sending the first message to the terminal device activates the terminal device to measure the reference signal of the first cell and, by configuring the measurement results to be reported in a physical layer (Layer 1) encoding format, lays the foundation for the terminal device to report the measurement results to the network device. This allows the terminal device to report the measurement results of the first cell in physical layer (Layer 1) encoding format to the network device promptly and quickly.

[0060] Figure 1 This is a schematic diagram of a communication system architecture, such as... Figure 1 As shown, the communication system of this application may include at least one network device and at least one terminal device, and the network device and the terminal device can communicate with each other. Figure 1 The example shown uses one network device and multiple terminals.

[0061] The three main application scenarios for 5G NR are: enhanced mobile broadband (eMBB), ultra-reliable low latency communications (uRLLC), and massive machine-type communication (mMTC). To meet these application scenarios, 5G NR can introduce high-frequency bands to achieve greater bandwidth and higher transmission rates. However, due to the higher frequency, signals experience significant fading during propagation. Therefore, 5G NR employs beamforming (BF) technology to achieve good directional gain, thereby increasing directional power in the transmit direction, improving the signal-to-interference-plus-noise ratio (SINR) at the receiver, and ultimately enhancing system performance. Considering the trade-off between cost and performance, 5G NR often uses hybrid beamforming (HBF) technology, which combines digital and analog beamforming.

[0062] Furthermore, mobility management is a crucial component of wireless mobile communication, ensuring that the communication link between network devices and terminal devices is not interrupted due to the movement of terminal devices. In 5G NR, mobility management primarily involves inter-cell mobility and intra-cell mobility, with measurement and reporting being the main steps. Typically, the measurement and reporting process includes: the network device configuring measurement and reporting for the terminal device; the terminal device performing measurements on the corresponding configured resources according to the network device's measurement configuration; and after measurement, reporting to the network device according to the network device's reporting configuration so that handover between cells and within cells can be performed based on the measurement results.

[0063] Because the measurement and reporting procedures differ between inter-cell and intra-cell operations, the protocol stipulates that different frameworks should be used to implement mobility management between and within cells. Specifically, radio resource measurement (RRM) is used for inter-cell mobility management, while beam management (BM) is used for intra-cell mobility management.

[0064] Below, in conjunction with Figure 2 Examples of mobility management within and between residential communities will be provided for illustration. For ease of explanation, Figure 2In the diagram, a mobile phone is used as an example of the terminal device. Path 1 and Path 2 are indicated by arrows. The diagram is illustrated using cell 1, which includes four transmission and reception points (TRPs) TRP1, TRP2, TRP3 and TRP4, and cell 2, which includes four TRPs TRP5, TRP6, TRP7 and TRP8.

[0065] like Figure 2 As shown, if the terminal device moves from TRP3 to TRP4 according to path 1, the terminal device uses RRM to implement mobility management within cell 1. If the terminal device moves from TRP2 to TRP7 according to path 2, the terminal device uses BM to implement mobility management between cell 1 and cell 2.

[0066] In addition, continue to combine Figure 2 When cell 1 and cell 2 belong to the same set, mobility management between them can be called intra-set mobility management. When cell 1 and cell 2 do not belong to the same set, mobility management between them can be called inter-set mobility management. Here, "set" can also be called a cluster or group, etc.

[0067] The following describes the specific implementation method of inter-cell mobility management using RRM for terminal devices.

[0068] Typically, network devices notify terminal devices of RRM measurement and reporting configuration information via RRC layer signaling. This configuration information is used to configure the reference signal, reference signal type, measurement quantity, and measurement cell for RRM measurements; specific parameters are described above and will not be repeated here. The terminal device then performs RRM measurements based on this configuration information. RRM measurements can be divided into two parts: physical layer (Layer-1) measurements and RRC layer (Layer-3) measurements. During physical layer (Layer-1) measurements, the terminal device measures the reference signal corresponding to the configured measurement quantity on the relevant configured resources to obtain the measurement results. The physical layer (Layer-1) measurement process can serve as an intermediate step in the RRC layer (Layer-3) measurement, and its measurement results can be considered intermediate results of the RRC layer (Layer-3) measurement.

[0069] Subsequently, for SSB-based measurements, the terminal device can perform various operations on the measurement results obtained on at least one SSB resource with the same SSB index and Physical Cell Identifier (PCI), such as summation, averaging, and selection of maximum and minimum values, to obtain the beam-level physical layer (Layer 1) measurement results of the SSB resource corresponding to the SSB index of the cell corresponding to the PCI, and report it to the RRC layer (Layer 3).

[0070] Subsequently, for CSI-RS-based measurements, the terminal device can perform various calculation operations on the measurement results obtained on at least one CSI-RS resource with the same CSI-RS resource identifier and PCI, such as summation, averaging, and selection of maximum and minimum values, to obtain the beam-level physical layer (Layer 1) measurement results of the CSI-RS resource corresponding to the CSI-RS resource identifier of the cell corresponding to the PCI, and report it to the RRC layer (Layer 3).

[0071] After receiving the beam-level measurement results reported by the physical layer (Layer 1) at the RRC layer (Layer 3), the terminal device needs to perform calculations on the physical layer (Layer 1) measurement results of each beam in the same cell to derive the RRC layer (Layer 3) measurement results for that cell. Afterward, the terminal device also needs to perform RRC layer (Layer 3) integration on the obtained cell-level RRC layer (Layer 3) measurement results.

[0072] The above-mentioned operation can be understood as the filtering operation performed by the terminal device on multiple measurement results obtained from a single measurement through a physical layer (Layer 1) filter. The above-mentioned integration operation can be understood as the filtering operation performed by the terminal device on the measurement results obtained from multiple measurements through an RRC layer (Layer 3) filter.

[0073] In addition, according to this configuration information, the terminal device may also need to report beam-level RRC layer (Layer 3) measurement results. In this case, the terminal device directly performs RRC layer (Layer 3) filtering on the physical layer (Layer 1) measurement results of each beam, and then selects the measurement results to be reported from the filtered measurement results.

[0074] Typically, protocols require terminal devices to verify the reporting trigger conditions at least when measurement results for a new cell are generated. When the reporting trigger conditions are met, the terminal device needs to send a measurement report to the network device based on this configuration information, via RRC layer encapsulation.

[0075] This configuration information is also used to configure reporting criteria such as event triggering or periodic triggering, reporting formats such as reporting cell-level measurements or reporting cell-level and beam-level measurements, measurement types, number of reported cell-level measurements, and number of reported beam-level measurements.

[0076] In summary, the above content constitutes the framework of RRM. Terminal devices perform RRM measurements based on the measurement configuration and instructions of the RRC layer (Layer 3), and report the measurement reports to network devices through the RRC layer (Layer 3) based on the reporting configuration, enabling terminal devices to achieve inter-cell mobility management.

[0077] The following describes the specific implementation method of using BM for mobility management within a cell for terminal devices.

[0078] Typically, network devices notify terminal devices of BM measurement configuration information via RRC layer (Layer 3) signaling and / or MAC layer (Layer 2) signaling and / or physical layer (also called Layer 1) signaling. This configuration information is used to configure the reference signals, measurement quantities, etc., for BM measurements; specific parameters are described above and will not be repeated here. The terminal device then performs BM measurements based on this configuration information and obtains the measurement results.

[0079] Furthermore, the network device notifies the terminal device of the configuration information reported by the BM via RRC layer (Layer 3) signaling and / or MAC layer (Layer 2) signaling and / or physical layer (Layer 1) signaling. Therefore, when the reporting trigger condition is met, the terminal device needs to send a measurement report to the network device based on this configuration information, using physical layer (Layer-1) encoding format.

[0080] This configuration information is used to configure various reporting configurations, namely periodic reporting based on periodic CSI-RS, semi-persistent reporting based on periodic or semi-persistent CSI-RS, and aperiodic reporting based on periodic, semi-persistent, or aperiodic CSI-RS.

[0081] When this configuration information is used to configure periodic reporting, the terminal device can only perform measurements based on the periodic CSI-RS resources, and the terminal device can send measurement reports to the network device on the physical uplink control channel (PUCCH).

[0082] When this configuration information is used to configure semi-persistent reporting, the terminal device can perform measurements based on periodic or semi-persistent CSI-RS resources, and the terminal device can send measurement reports to the network device on the PUCCH or the physical uplinkshare channel (PUSCH). Specifically, when the network device sends a medium access control sublayer (MAC, MAC-CE) command (also called Layer 2, such as MAC-customer edge, MAC-CE command) or downlink control information (DCI) to the terminal device to activate / deactivate the terminal device for semi-persistent reporting, the terminal device can send measurement reports to the network device on the PUSCH.

[0083] When this configuration information is used to configure aperiodic reporting, the terminal device can perform measurements based on periodic, semi-persistent, or aperiodic CSI-RS resources, and the terminal device can send measurement reports to the network device on the PUSCH.

[0084] In summary, the above content constitutes the framework of BM. The terminal device performs BM measurements based on the measurement configuration of RRC layer (Layer 3) instructions, the instructions of MAC layer (Layer 2) and physical layer (Layer 1) instructions, and reports the measurement report to the network device through physical layer (Layer 1) based on the reporting configuration of RRC layer (Layer 3), enabling the terminal device to achieve mobility management within the cell.

[0085] Based on the above description, since the BM framework only configures the relevant settings for the serving cell and not the relevant settings for non-serving cells, while the RRC framework configures the relevant settings for both serving and non-serving cells, terminal devices using BM cannot achieve inter-cell mobility management. Furthermore, although terminal devices can use RRM to achieve inter-cell mobility management, the reporting of RRM measurement results through the RRC layer (Layer 3) results in a large reporting delay, making it impossible to achieve beam selection for fast inter-cell movement.

[0086] To address the aforementioned issues, this application provides a communication method, apparatus, device, and computer storage medium. Based on the fact that the latency generated by reporting measurement results through the physical layer (Layer 1) is much smaller than that of reporting measurement results through the RRC layer (Layer 3), the terminal device can be configured to report measurement results to the network device through the physical layer (Layer 1) encoding format, thereby reducing inter-cell mobility latency. This enables beam selection for rapid inter-cell mobility, improves performance in high-speed mobility scenarios, and ultimately achieves the service requirements of low latency and high reliability.

[0087] Below, this application uses Figure 1 Terminal devices and network devices in the process are the main implementers, combined with Figure 3 The specific implementation process of the communication method in this application will be described in detail.

[0088] Figure 3 A signaling flowchart of a communication method provided in an embodiment of this application is shown below. Figure 3 As shown, the communication method of this application may include:

[0089] S101. The network device determines a first message, which instructs the terminal device to measure the reference signal of the first cell and configures the measurement results to be reported in a physical layer (Layer 1) encoding format. The first cell includes at least one non-serving cell of the terminal device, or the first cell includes at least one serving cell and at least one non-serving cell of the terminal device. In this application, the network device can determine a first message, which can not only instruct the terminal device to measure the reference signal of the first cell to activate the terminal device to measure the reference signal of the first cell, but also configure the measurement results to be reported in a physical layer (Layer 1) encoding format, laying the foundation for the terminal device to report the measurement results to the network device, so that the terminal device can report the measurement results of the first cell in physical layer (Layer 1) encoding format to the network device in a timely and rapid manner.

[0090] This application does not limit the number or type of the first message. Optionally, the first message may include at least one of the following: RRC layer (Layer 3) information, MAC layer (Layer 2) control information, or physical layer (Layer 1) dynamic control information.

[0091] For example, a network device can determine a first message based on any of the above types of information, so as to activate the terminal device to measure the reference signal of the first cell and configure the measurement results to be reported in the physical layer (Layer 1) encoding format, which helps to save network device configuration instructions.

[0092] For example, network devices can determine multiple first messages based on any number of the above types of information, so that the terminal device can be activated to measure the reference signal of the first cell through a portion of the first messages, and the remaining first messages can be used to configure the measurement results to be reported in the physical layer (Layer 1) encoding format. The design is simple and convenient.

[0093] This application does not limit the specific instruction form of the first message. For example, this application can use one or more information bits in the first message to activate the terminal device to measure the reference signal of the first cell and configure the measurement results to be reported in physical layer (Layer 1) encoding format. Furthermore, the physical layer (Layer 1) encoding format refers to the format suitable for encoding in the physical layer (Layer 1), and this application does not limit it.

[0094] In this application, the first cell may include: one or more non-serving cells of terminal devices. Alternatively, the first cell may include: one or more serving cells of terminal devices and one or more non-serving cells of terminal devices. The cell type may include: serving cell and non-serving cell.

[0095] The serving cell may include at least one primary cell (PCell) and at least one secondary cell (SCell). The primary cell operates on the primary frequency band. The terminal device performs the initial connection establishment process or begins the connection re-establishment process in this cell. During handover, this cell is designated as the primary cell. The secondary cell operates on the secondary frequency band. Once the RRC connection is established, the secondary cell may be configured to provide additional radio resources. Cells other than those mentioned above are non-serving cells.

[0096] For terminal devices in RRC connected state, if carrier aggregation (CA) is not configured, there is only one primary serving cell. If CA is configured, the serving cell can consist of a primary cell and a secondary cell. Thus, the terminal device can perform cell handover. For terminal devices in RRC idle state (RRC_IDLE) or RRC inactive state (RRC_INACTIVE), the serving cell can also be understood as the cell corresponding to the system information (SI) received by the terminal device; other cells are non-serving cells. It should be noted that the cell range covered by the first cell can be configured by the network device, predefined by the protocol, or pre-stored in the terminal device; this application does not limit this.

[0097] When the cell range covered by the first cell is predefined by the protocol or pre-stored in the terminal device, the terminal device can directly determine the cell range covered by the first cell. When the cell range covered by the first cell is configured through network devices, the network devices can adopt various implementation methods to enable the terminal device to determine the cell range covered by the first cell.

[0098] Optionally, the network device can inform the terminal device through the first message, so that the terminal device can determine the cell range covered by the first cell based on the first message, thereby saving instruction commands.

[0099] The first message can be used to indicate part or all of the non-serving cells of the terminal device, or it can be used to indicate part or all of the non-serving cells of the terminal device and part or all of the serving cells of the terminal device. This application does not limit this.

[0100] Alternatively, the network device can inform the terminal device through the fifth message, so that the terminal device can determine the cell range covered by the first cell based on the fifth message. This design is simple and convenient.

[0101] The fifth message can be used to indicate part or all of the non-serving cells of the terminal device, or it can be used to indicate part or all of the non-serving cells of the terminal device and part or all of the serving cells of the terminal device. This application does not limit this.

[0102] Alternatively, the network device can inform the terminal device through the first message and the fifth cell, so that the terminal device can determine the cell range covered by the first cell based on the first message and the fifth message, in order to deal with emergencies such as temporary poor cell signal.

[0103] For example, the terminal device may determine the cell range covered by the first cell by the intersection of the cell range determined by the first message and the cell range determined by the fifth message, or it may determine the cell range covered by the first cell by the total set of the cell range determined by the first message and the cell range determined by the fifth message. This application does not limit this.

[0104] The specific implementation of the first and fifth messages is not limited. Optionally, the first and / or fifth messages can be used to indicate the maximum number of first cells that the terminal device measures based on the first message, or the cell set of the first cells that the terminal device measures based on the first message, or the maximum number of first cells and the cell set that the terminal device measures based on the first message. This application does not limit the scope of these indications.

[0105] The network device can send a first message and a fifth message to the terminal device, respectively. The order in which the first and fifth messages are sent is not limited, or the first and fifth messages can be sent to the terminal device simultaneously. This application does not limit the number or type of the fifth message. Optionally, the type of the fifth message may include at least one of the following: RRC layer (Layer 3) information, MAC layer (Layer 2) control information (such as MAC-CE commands), or physical layer (Layer 1) dynamic control information (such as DCI). Furthermore, this application does not limit the specific indication format of the fifth message. For example, this application can configure the cell range covered by the first cell using one or more information bits in the fifth message.

[0106] In addition, since measurement and reporting are the main steps of mobility management, network devices can also be configured with information related to the terminal device measuring the reference signal of the first cell, so as to configure the terminal device to implement inter-cell mobility management.

[0107] The network device can employ various implementation methods to configure the relevant information for the terminal device to measure the reference signal of the first cell. Optionally, the network device can configure the relevant information for the terminal device to measure the reference signal of the first cell through a first message, or through other messages, or through a combination of the first message and other messages. This application does not limit the specific implementation methods.

[0108] For example, the first message can not only be used to activate the terminal device to measure the reference signal of the first cell and configure the measurement results to be reported in the physical layer (Layer 1) encoding format, but also to configure the relevant information of the measurement of the first cell, thereby saving the configuration instructions of the network device.

[0109] For example, the first message can be used to activate the terminal device to measure the reference signal of the first cell and configure the measurement results to be reported in the physical layer (Layer 1) encoding format. Other messages can be used to configure the relevant information of the measurement of the first cell. The design is simple and convenient.

[0110] For example, the first message can be used to activate the terminal device to measure the reference signal of the first cell and configure the measurement results to be reported in the physical layer (Layer 1) encoding format. Other messages and the first message can be used together to configure the relevant information of the measurement of the first cell, so as to provide a possibility.

[0111] The network device can send a first message and other messages to the terminal device separately. The order in which the first message and other messages are sent is not limited, and the first message and other messages can also be sent to the terminal device simultaneously. This application does not limit the number or type of other messages. Other messages can be of the same type as the first message, or they can be of different types. Optionally, other messages may include at least one of: RRC layer (Layer 3) information, MAC layer (Layer 2) control information, or physical layer (Layer 1) dynamic control information. Furthermore, this application does not limit the specific indication form of other messages. For example, this application can configure measurement-related information of the first cell using one or more information bits from other messages.

[0112] S102, The network device sends the first message to the terminal device.

[0113] S103. The terminal device obtains the measurement result of the first cell based on the first message. The measurement result of the first cell is used by the terminal device to perform cell selection, cell reselection or cell handover.

[0114] In this application, the network device can send a first message to the terminal device to activate the terminal device to measure the reference signal of the first cell and configure the measurement results to be reported in a physical layer (Layer 1) encoding format. Then, based on the first message, the terminal device can obtain the measurement results of the first cell.

[0115] This application does not limit the specific representation of the measurement results of the first cell. Furthermore, the measurement results of the first cell can be used by the terminal device for cell selection, cell reselection, or cell handover. Typically, when the terminal device is in RRC idle / RRC inactive state, it can perform cell selection or cell reselection based on the measurement results of the first cell. When the terminal device is in RRC connected state, it can perform cell handover based on the measurement results of the first cell.

[0116] Based on the above, considering that the latency of reporting measurement results through the physical layer (Layer 1) is less than that of reporting measurement results through the RRC layer (Layer 3), compared with the terminal device using RRM for inter-cell mobility management, the terminal device based on the communication method of this application can report the measurement results of the first cell in physical layer (Layer 1) encoding format to the network device in a timely and fast manner, reducing the mobility latency of the terminal device between cells and facilitating beam selection for rapid inter-cell movement.

[0117] The communication method provided in this application determines a first message through a network device. This first message not only instructs a terminal device to measure the reference signal of a first cell, but also configures the measurement results to be reported in a physical layer (Layer 1) encoding format. The first cell includes at least one non-serving cell of the terminal device, or the first cell includes at least one serving cell and at least one non-serving cell of the terminal device. Sending the first message from the network device to the terminal device not only activates the terminal device to measure the reference signal of the first cell, but also lays the foundation for the terminal device to report the measurement results to the network device by configuring the measurement results to be reported in a physical layer (Layer 1) encoding format. This allows the terminal device to report the measurement results of the first cell in physical layer (Layer 1) encoding format to the network device in a timely and rapid manner. This not only realizes inter-cell mobility management but also reduces the inter-cell movement latency of the terminal device, facilitating beam selection for rapid inter-cell movement.

[0118] Those skilled in the art will understand that in the BM framework, the terminal device performs BM measurements based on physical layer (Layer 1) measurements. In the RRM framework, the terminal device performs RRM measurements based on both physical layer (Layer 1) measurements and RRC layer (Layer 3) measurements, and the duration measured based on RRC layer (Layer 3) measurements is significantly longer than the duration measured based on physical layer (Layer 1) measurements. Here, the measured quantities can be understood as performance indicators that measure the reference signal, such as RSRP, RSRQ, or SINR.

[0119] Based on this, in this application, the terminal device can measure the reference signal of the first cell according to the physical layer (Layer 1) measurement, so as to shorten the measurement time, further reduce the inter-cell mobility latency, so as to realize beam selection for fast inter-cell mobility, which is conducive to improving the performance of high-speed mobility scenarios, thereby achieving the service requirements of low latency and high reliability.

[0120] The operation of the terminal device measuring the reference signal of the first cell based on the physical layer (Layer 1) measurement can be configured by the network device, such as by using the first message or other messages for indication, or it can be defined by the protocol, or it can be selected by the terminal device itself. This application does not limit this.

[0121] Based on the above description, terminal devices can employ various implementation methods to achieve cell selection, cell reselection, or cell handover. Below, we will discuss this in conjunction with... Figure 4 and Figure 5 The following examples illustrate the specific implementation process of cell selection, cell reselection, or cell handover in the terminal device of this application.

[0122] In Embodiment 1, the terminal device can perform cell selection, cell reselection, or cell handover based on the judgment made by the network device. In Embodiment 2, the terminal device performs cell selection, cell reselection, or cell handover based on the measurement results of the first cell.

[0123] Example 1

[0124] Figure 4 A signaling flowchart of a communication method provided in an embodiment of this application is shown below. Figure 4 As shown, the communication method of this application may include:

[0125] S201. The network device determines a first message, which is used to instruct the terminal device to measure the reference signal of the first cell and configure the measurement results to be reported in a physical layer encoding format. The first cell includes at least one non-serving cell of the terminal device, or the first cell includes at least one serving cell and at least one non-serving cell of the terminal device.

[0126] S202, The network device sends the first message to the terminal device.

[0127] S203. The terminal device obtains the measurement result of the first cell based on the first message. The measurement result of the first cell is used by the terminal device to perform cell selection, cell reselection or cell handover.

[0128] Among them, S201, S202 and S203 are respectively with Figure 3 The implementations of S101, S102, and S103 in the illustrated embodiments are similar, and will not be described again here.

[0129] S204. Based on the first message, the terminal device processes the measurement results of the first cell into a physical layer encoding format to obtain the measurement results of the first cell in physical layer encoding format.

[0130] Since the first message is used to configure the measurement results to be reported in physical layer (Layer 1) encoding format, the terminal device can process the measurement results of the first cell in physical layer (Layer 1) encoding format based on the first message to obtain the measurement results of the first cell in physical layer encoding format.

[0131] In this process, the terminal device can report the measurement results of the first cell to the network device after receiving an instruction from the network device. The specific implementation process is described below, using two concrete implementation methods.

[0132] In one feasible implementation, the network device can send a second message to the terminal device, which instructs the terminal device to report the measurement results of the first cell to the network device, so that the terminal device can report the measurement results of the first cell based on the second message. This design is simple and convenient.

[0133] In another feasible implementation, the network device can inform the terminal device through a first message, which instructs the terminal device to report the measurement results of the first cell to the network device, so that the terminal device can report the measurement results of the first cell based on the first message, thereby saving configuration instructions.

[0134] S205. The terminal device reports a third message to the network device, which includes the measurement results of the first cell in physical layer coding format.

[0135] In this application, the terminal device can include the measurement results of the first cell in physical layer coding format in a third message, so that the terminal device can send the third message to the network device. This application does not limit the type or quantity of the third message. Optionally, the type of the third message may include at least one of: RRC layer (Layer 3) information, MAC layer (Layer 2) control information, or physical layer (Layer 1) dynamic control information. Furthermore, this application does not limit the specific indication format of the third message. For example, this application can configure the measurement results of the first cell in physical layer coding format using one or more information bits in the third message.

[0136] S206. The network device sends a fourth message to the terminal device. The fourth message is obtained from the measurement results of the first cell based on the physical layer coding format. The fourth message is used to instruct the terminal device to perform cell selection, cell reselection, or cell handover.

[0137] In this application, the network device can obtain the measurement results of the first cell in physical layer coding format from the received third message, and obtain a fourth message based on the measurement results of the first cell in physical layer coding format. The four messages are used to instruct the terminal device to perform cell selection, cell reselection or cell handover.

[0138] This application does not limit the type or quantity of the fourth message. Optionally, the type of the fourth message may include at least one of RRC layer (Layer 3) information, MAC layer (Layer 2) control information, or physical layer (Layer 1) dynamic control information. Furthermore, this application does not limit the specific indication format of the fourth message. For example, this application can use one or more information bits in the fourth message to instruct the terminal device to perform cell selection, cell reselection, or cell handover.

[0139] S207. The terminal device performs cell selection, cell reselection, or cell handover based on the fourth message.

[0140] Since the fourth message can be used to instruct the terminal device to perform cell selection, cell reselection, or cell handover, the terminal device can perform these actions based on the received fourth message. For example, when the fourth message instructs the terminal device to perform cell selection, the terminal device performs cell selection. When the fourth message instructs the terminal device to perform cell reselection, the terminal device performs cell reselection. When the fourth message instructs the terminal device to perform cell handover, the terminal device performs cell handover.

[0141] In addition, the fourth message can also be used to instruct the terminal device to select, reselect, or hand over the corresponding cell. For example, the fourth message may contain the identification information of the cell so that the terminal device can select the cell corresponding to the identification information to perform cell selection, cell reselection, or cell handover.

[0142] Example 2

[0143] Figure 5 A signaling flowchart of a communication method provided in an embodiment of this application is shown below. Figure 5 As shown, the communication method of this application may include:

[0144] S301. The network device determines a first message, which is used to instruct the terminal device to measure the reference signal of the first cell and configure the measurement results to be reported in a physical layer encoding format. The first cell includes at least one non-serving cell of the terminal device, or the first cell includes at least one serving cell and at least one non-serving cell of the terminal device.

[0145] S302, The network device sends the first message to the terminal device.

[0146] S303. The terminal device obtains the measurement result of the first cell based on the first message. The measurement result of the first cell is used by the terminal device to perform cell selection, cell reselection or cell handover.

[0147] Among them, S301, S302 and S303 are respectively with Figure 3 The implementations of S101, S102, and S103 in the illustrated embodiments are similar, and will not be described again here.

[0148] S304. The terminal device performs cell selection, cell reselection, or cell handover based on the measurement results of the first cell.

[0149] Since the measurement results of the first cell can represent the performance indicators of the first cell, the terminal device can perform cell selection, cell reselection, or cell handover based on the measurement results of the first cell without having to obtain information on cell selection, cell reselection, or cell handover through network devices. The operation is simple and convenient, saving signaling overhead.

[0150] Considering that the measurement results of the first cell may fluctuate significantly, the terminal device may optionally obtain a first threshold. Based on the measurement results of the first cell and the first threshold, the terminal device can perform cell selection, cell reselection, or cell handover to reduce repeated operations of cell selection, cell reselection, or cell handover, thereby reducing the wear and tear on the terminal device and mitigating some of the ping-pong effect.

[0151] For example, based on the measurement results of the first cell, the terminal device can compare the difference between the measurement results of the non-serving cell and the measurement results of the serving cell with a first threshold. If the difference is greater than the first threshold, the terminal device performs cell selection, cell reselection, or cell handover; if the difference is less than or equal to the first threshold, the terminal device does not perform cell selection, cell reselection, or cell handover.

[0152] The first threshold can be configured through network devices, defined by a protocol, or pre-stored in the terminal device; this application does not impose any limitations on this. When the first threshold is pre-defined by a protocol or pre-stored in the terminal device, the terminal device can directly determine the first threshold. When the first threshold is configured through network devices, the network devices can employ various implementation methods to enable the terminal device to determine the first threshold.

[0153] Optionally, the network device can inform the terminal device through the first message, so that the terminal device can determine the first threshold based on the first message, thereby saving instruction commands.

[0154] Alternatively, network devices can inform terminal devices through other messages, enabling terminal devices to determine the first threshold based on these messages, a design that is simple and convenient.

[0155] Alternatively, the network device can inform the terminal device through the first message and other cells, so that the terminal device can determine the first threshold based on the first message and other messages in order to deal with sudden situations where the first threshold is temporarily changed.

[0156] In summary, regardless of whether it is Embodiment 1 or Embodiment 2, the terminal device achieves inter-cell mobility management. It should be noted that the terminal device can execute the steps of Embodiment 1, the steps of Embodiment 2, or both; this application does not limit this.

[0157] Based on the above description, network devices can adopt various implementation methods to realize the process of determining the first message in S101.

[0158] In one feasible implementation, the terminal device can send a sixth message to the network device. This sixth message indicates whether the terminal device has the capability to measure the first cell. Based on the sixth message, the network device can determine whether the terminal device has the capability to measure the first cell. Thus, the network device determines the first message by combining the actual situation and the terminal device's capability to measure the first cell.

[0159] This application does not limit the type or quantity of the sixth message. Optionally, the type of the sixth message may include at least one of RRC layer (Layer 3) information, MAC layer (Layer 2) control information, or physical layer (Layer 1) dynamic control information. Furthermore, this application does not limit the specific indication format of the sixth message. For example, this application may use one or more information bits in the sixth message to indicate whether the terminal device has the capability to measure the first cell.

[0160] In another feasible implementation, the network device can obtain predefined information indicating whether the terminal device has the ability to measure the first cell, based on the actual situation of the device's network access, so that the network device can determine the first message based on the actual situation and the information.

[0161] Based on the foregoing description, the information in the first message can include various representations for obtaining the measurement results of the first cell. Examples of the representations of the information in the first message are given below.

[0162] In one possible representation, the information in the first message may include: first information, which is used by the terminal device to measure the reference signal of the first cell. That is, based on the first information, the terminal device can measure the reference signal of the first cell to obtain the measurement result of the first cell.

[0163] Optionally, when the first message includes the first information, the network device can also trigger / activate the terminal device to perform the following process through the first message and / or other messages: the terminal device measures the reference signal of the first cell based on the first information in order to obtain the measurement result of the first cell. Alternatively, the terminal device measures the reference signal of the first cell according to the physical layer (Layer 1) measurement based on the first information in order to obtain the measurement result of the first cell.

[0164] The first information may be the software program executed by the terminal device to measure the reference signal of the first cell, and this application does not limit the specific content of the first information. Optionally, the first information may specifically include: configuration information of the reference signal of the first cell, configuration information of the QCL relationship between the serving cell and the non-serving cell in the first cell, and configuration information of beam failure recovery management of the first cell. In addition, the configuration information of the QCL relationship between the serving cell and the non-serving cell in the first cell and the configuration information of beam failure recovery management of the first cell may also be used for other functions such as data transmission, which will not be elaborated here.

[0165] In another feasible representation, the information in the first message may include: second information, which instructs the terminal device to invoke third information, which is used to obtain the measurement results of the first cell. That is, under the instruction of the second information, the terminal device can invoke the third information to obtain the measurement results of the first cell.

[0166] The second information may be a software instruction that instructs the terminal device to invoke the software corresponding to the third information. The third information may be a software program of the existing RRM or a software program executed by the terminal device to measure the reference signal of the first cell.

[0167] Optionally, when the first message includes the second information, the network device can also trigger / activate the terminal device to perform the following process through the first message and / or other messages: Based on the second information, the terminal device can invoke the third information and measure the reference signal of the first cell based on the third information to obtain the measurement result of the first cell. Alternatively, based on the second information, the terminal device can invoke the third information and measure the reference signal of the first cell according to the physical layer (Layer 1) measurement based on the third information to obtain the measurement result of the first cell.

[0168] In another feasible representation, the information in the first message may include: fourth information, which instructs the terminal device to retrieve the measurement results of the first cell. That is, the terminal device can retrieve the measurement results of the first cell under the instruction of the fourth information.

[0169] The fourth piece of information may be a software instruction that instructs the terminal device to obtain the measurement results of the first cell. The measurement results of the first cell may be obtained by the software program of the RRM in the prior art or by the software program executed by the terminal device to measure the reference signal of the first cell, and this application does not limit it.

[0170] Optionally, when the first message includes the fourth information, the network device can also trigger / activate the terminal device to perform the following process through the first message and / or other messages: the terminal device can call and directly obtain the measurement results of the first cell based on the fourth information.

[0171] It should be noted that, in addition to the above representations, the first message can also employ any combination of the above representations. Furthermore, the first message can also be used solely to instruct the terminal device to measure the reference signal of the first cell, serving as an indication / activation / trigger. This allows the measurement result of the first cell obtained based on the third information to be transmitted to the terminal device via a configured interface, enabling the terminal device to obtain the measurement result of the first cell from the configured interface based on the first message. Moreover, besides configuring via network devices, triggering / activating any process executed by the terminal device can also be implemented by a protocol definition or pre-configured within the terminal device.

[0172] The other messages differ from the first message, and their specific implementations can be found in the foregoing content, so they will not be repeated here. Furthermore, the network device can also configure each reference signal in the third information to be at least one of periodic, semi-perpetual, or aperiodic via the first message or the other messages, so that the communication method of this application can be applied to various types of reference signals.

[0173] To save signaling overhead, in this application, the network device may also trigger the terminal device to report the measurement results of the first cell, or the measurement results of the non-serving cell in the first cell, or the measurement results of the serving cell in the first cell to the network device through the first message or other messages. This application does not limit this.

[0174] To standardize the format reported by terminal devices, in this application, the network device can also configure the reporting method of measurement results through a first message or other messages. This application does not limit the specific implementation method of the reporting method.

[0175] Optionally, the reporting method is to process the measurement results of the first cell into a physical layer encoding format before reporting.

[0176] Alternatively, the reporting method involves processing the measurement results of the first cell and the identification information of the corresponding indications of the first cell into a physical layer encoding format before reporting.

[0177] Alternatively, the reporting method may involve processing the measurement results of the first cell and the identification information of the reference signal corresponding to the measurement results of the first cell into a physical layer encoding format before reporting.

[0178] Alternatively, the reporting method may involve processing the measurement results of the first cell, the identification information of the reference signal corresponding to the measurement results of the first cell, and the identification information of the cell corresponding to the measurement results of the first cell into a physical layer encoding format before reporting.

[0179] Alternatively, the reporting method involves processing the measurement results of non-serving cells in the first cell into a physical layer encoding format before reporting.

[0180] Alternatively, the reporting method involves physically encoding the measurement results of non-serving cells in the first cell and the identification information of the cells corresponding to the measurement results of non-serving cells in the first cell before reporting them.

[0181] Alternatively, the reporting method involves processing the measurement results of non-serving cells in the first cell and the identification information of the reference signals corresponding to the measurement results of non-serving cells in the first cell into a physical layer encoding format before reporting.

[0182] Alternatively, the reporting method involves processing the measurement results of non-serving cells in the first cell, the identification information of the cells corresponding to the measurement results of non-serving cells in the first cell, and the identification information of the reference signals corresponding to the measurement results of non-serving cells in the first cell into a physical layer encoding format before reporting.

[0183] Alternatively, the reporting method may be a physical layer encoding process applied to the measurement results of the first cell, the identification information of the cell corresponding to the measurement results of the non-serving cell in the first cell, and the identification information of the reference signal corresponding to the measurement results of the first cell.

[0184] It should be noted that, in addition to configuring via network devices, the method for reporting measurement results can also be defined by a protocol or pre-configured in the terminal device.

[0185] To save signaling overhead, in this application, the network device can also use a first message or other messages to configure the terminal device to perform physical layer encoding on the identification information of one of the multiple identical cell identification information. That is, for the same cell identification information, the terminal device reports the cell identification information in physical layer encoding format to the network device once.

[0186] This application does not limit the specific implementation method of the cell identification information. Optionally, the cell identification information includes: a cell ID or other information, wherein the other information has a mapping relationship with the cell ID. The cell ID may include, but is not limited to, a number, PCI, or other forms of identifier. Since there are many cells, the value corresponding to the cell ID will be very large. When a terminal device reports a large cell ID to the network device, the cell ID may occupy multiple information bits. Therefore, the terminal device can also represent the cell identification information based on other information that has a mapping relationship with the cell ID, in order to save signaling overhead.

[0187] It should be noted that, in addition to configuring via network devices, the physical layer encoding of the identifier information of one of the multiple identical cell identifiers by the terminal device can also be achieved by protocol definition or pre-configuration in the terminal device.

[0188] In addition, terminal devices can typically report the measurement results of the first physical layer coded cell to the network device in the form of tables or reports. Simultaneously, the terminal device can also report parameters such as the cell index, cell identification information, measurement quantities, and reference signals. Below, we will illustrate the reporting of measurement results of the first physical layer coded cell by the terminal device to the network device using a table format.

[0189] In a specific embodiment, if the first cell only includes non-serving cells of at least one terminal device, taking cell 1, cell 2, cell 3 and cell 4 as an example, the terminal device can report the measurement results of the physical layer encoded first cell to the network device in the form of Table 1 or Table 2.

[0190] Cell index PCI of the community SSB RI / CRI Reported value 1 Community ID01 #xx1 Absolute value 2 Community ID15 #xx2 Differential value 1 3 Community ID15 #xx3 Difference value 2 4 Community ID68 #xx4 Differential value 3

[0191] Table 2

[0192]

[0193] In Tables 1 and 2, the measurement results of the first cell coded by the physical layer include: the cell index, the cell identification information (such as PCI), the resource indication of the reference signal (such as the synchronization signal block resource indicator (SSB RI) or the channel state information reference signal resource indicator (CSI-RS, CRI)) and the reported value (i.e. the measurement result).

[0194] The difference between Table 1 and Table 2 is that Table 1 shows two indices and two PCIs for cell 2, while Table 2 shows one index and one PCI for cell 2. In another specific embodiment, if the first cell includes at least one non-serving cell of a terminal device and at least one serving cell of a terminal device, for example, the serving cell includes cell 0, and the non-serving cells include cells 1, 2, 3, and 4, then the terminal device can report the measurement results of the physically layer-coded first cell to the network device in the form shown in Table 3 or Table 4.

[0195] Cell index PCI of the community SSB RI / CRI Reported value 0 / #xx0 Absolute value 1 Community ID01 #xx1 Differential value 1 2 Community ID15 #xx2 Difference value 2 3 Community ID15 #xx3 Differential value 3 4 Community ID68 #xx4 Differential value 4

[0196] Table 4

[0197]

[0198] In Tables 3 and 4, the measurement results of the first cell coded by the physical layer include: cell index, cell identification information (such as PCI), resource indication of reference signal (such as SSB RI / CRI), and reported value.

[0199] The difference between Table 1 and Table 2 is that Table 3 shows two indices and two PCIs for cell 2, while Table 4 shows one index and one PCI for cell 2.

[0200] The reported values ​​can be submitted using either absolute or differential values. Specifically, one value is selected as the absolute value for submission, and the remaining values ​​are submitted as differential values ​​based on this absolute value. This reduces the dynamic range of the reported values, decreases the number of encoded bits, and thus saves signaling overhead. Alternatively, the reported values ​​can also be submitted using absolute values, specifically by submitting the absolute value of any given value. Furthermore, the reported values ​​can also be submitted using differential values, specifically by submitting the differential values ​​of all reported values ​​based on a preset absolute value. The preset absolute value can be configured by the network device or defined by the protocol; this application does not impose any limitations on this.

[0201] Furthermore, to reduce the overhead of cell identification information, this application can represent cell identification information using other information that is mapped to the cell ID. For example, cell ID01 is mapped to number 1; cell ID15 is mapped to number 2; and cell ID68 is mapped to number 3. This mapping relationship can be configured by network devices or defined by a protocol; this application does not limit this, as long as the mapping relationship between the terminal device (converting the cell ID to the mapping relationship corresponding to other information) and the mapping relationship between the network device (converting other information to the mapping relationship corresponding to the cell ID) are the same.

[0202] Based on the above, considering that in the process of using BM to implement mobility management within a cell, the terminal device performs BM measurements based on physical layer (Layer 1) measurements and reports the measurement report to the network device through physical layer (Layer 1), this application can reasonably utilize the BM framework. Based on the configuration of measuring the reference signal of the first cell according to physical layer (Layer 1) measurements and the configuration of reporting the measurement results through physical layer encoding format, the function of obtaining the measurement results of the first cell can be added on the basis of the BM framework to realize inter-cell mobility management.

[0203] On the one hand, since the information in the first message can be used to obtain the measurement results of the first cell, this application can add the information in the first message to the BM framework and use the measurement results configured in the BM framework to report to the network device through the physical layer (Layer 1), thereby realizing the communication method of this application and saving configuration instructions.

[0204] When the information in the first message includes the first information, the first information is added to the BM framework, enabling the terminal device to implement inter-cell mobility management using the BM framework with the added first information. Specifically, based on the first information, the terminal device measures the reference signal of the first cell according to the physical layer (Layer 1) measurements, obtains the measurement results of the first cell, and, based on the BM framework, configures the first cell measurement results to be reported in physical layer (Layer 1) encoding format.

[0205] When the information in the first message includes the second information, the second information is added to the BM framework, enabling the terminal device to implement inter-cell mobility management using the BM framework with the added second information. Specifically, based on the second information, the terminal device invokes the third information (such as the RRM framework), and based on the third information, measures the reference signal of the first cell according to the physical layer (Layer 1) measurements to obtain the measurement results of the first cell. Based on the BM framework, the terminal device configures the measurement results of the first cell to be reported in the physical layer (Layer 1) encoding format.

[0206] When the information in the first message includes the fourth information, the fourth information is added to the BM framework, enabling the terminal device to implement inter-cell mobility management using the BM framework with the added fourth information. Specifically, based on the fourth information, the terminal device retrieves the measurement results of the first cell from the RRM framework and, based on the BM framework, configures the measurement results to be reported in physical layer (Layer 1) encoding format.

[0207] On the other hand, this application can also configure an interface in the RRM framework that connects to the BM framework, so that the measurement results of the first cell obtained based on the RRM framework can be transmitted to the BM framework through the interface, so that the terminal device can obtain the measurement results of the first cell in the BM framework.

[0208] Furthermore, this application can also add cell identification information from the RRM framework to the BM framework. Since the cells corresponding to the cell identification information in the RRM framework include the first cell, and the cells corresponding to the cell identification information in the RRM framework limit the number of cells that can be added to the BM framework, this application can fully utilize the relevant configurations of the cells corresponding to the cell identification information in the RRM framework, enabling the terminal device to achieve inter-cell mobility management within the BM framework without adding additional configuration information, saving configuration commands and reducing unnecessary consumption.
