Description

[Technical Field]

[0001] The present application relates to the field of communication technologies, and in particular to communication methods and apparatus and devices. [Background technology]

[0002] The new radio (NR) of 5th generation mobile networks (5G) introduces higher frequency bands to achieve wider bandwidths and higher transmission speeds. Due to the higher frequencies, severe fading can occur during signal transmission in space. Therefore, 5G NR uses beamforming (BF) technology to improve performance.

[0003] In addition, mobility management has long been an important part of wireless mobile communications and can ensure that the communication link between a network device and a terminal device is not interrupted due to the movement of the terminal device. In 5G NR, mobility management is mainly performed in inter-cell mobility and intra-cell mobility modes, and measurement and reporting are the main steps of mobility management. Typically, a specific measurement and reporting process includes a network device performing measurement configuration and reporting configuration of the terminal device. The terminal device performs measurements on corresponding configuration resources based on the measurement configuration of the network device. After the measurement, the measurement results are reported to the network device based on the reporting configuration of the network device, thereby performing inter-cell handover and intra-cell handover based on the measurement results.

[0004] Since the inter-cell and intra-cell measurement and reporting steps are different, the protocol specifies that radio resource measurement (RRM) is used for inter-cell mobility management and beam management (BM) is used for intra-cell mobility management.

[0005] Both the measurement configuration information and reporting configuration information of the network device's RRM are notified to the terminal device using radio resource control (RRC) layer signaling. Reference signals for RRM measurements may include serving cell reference signals and non-serving cell reference signals. Reference signal types may include synchronization signal / physical broadcast channel block (SSB) and channel state information-reference signal (CSI-RS), etc. Measurement metrics may include cell-level and beam-level metrics at the RRC layer (also referred to as Layer 3), such as reference signal receive power (RSRP), reference signal receive quality (RSRQ), and signal interference noise radio (SINR). The configured cells may be intra-frequency cells, inter-frequency cells, or inter-system cells. The method for reporting the measurement result is that the terminal device encapsulates the measurement result into an RRC layer format and then reports the measurement result to the network device.

[0006] Both the measurement configuration information and reporting configuration information of the BM by the network device are notified to the terminal device using RRC layer (i.e., Layer 3) signaling and / or physical layer (also referred to as Layer 1) signaling. The reference signal for BM measurement includes only the reference signal of the serving cell. The measurement metrics may 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). The method for reporting the measurement results is for the terminal device to encapsulate the measurement results in a physical layer format and report them to the network device.

[0007] In conclusion, the terminal device cannot use BM to perform inter-cell mobility management. In addition, although the terminal device can use RRM to perform inter-cell mobility management, the delay in reporting the RRM measurement result is long, and beam selection during the process of high-speed inter-cell movement cannot be performed. Summary of the Invention [Means for solving the problem]

[0008] The present application provides a communication method and apparatus, and a device for implementing inter-cell mobility management, which further reduces the inter-cell movement delay of a terminal device and facilitates beam selection in the inter-cell high-speed movement process.

[0010] According to a communication method provided in a first aspect, a terminal device receives a first message from a network device.

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 manner, not only can the terminal device be operated to measure the reference signal of the first cell, but the measurement results can also be configured to be reported in a physical layer (Layer 1) coding format. This provides a basis for the terminal device to report the measurement results to the network device, thereby allowing the terminal device to report the measurement results of the first cell in a physical layer (Layer 1) coding format to the network device in a timely and fast manner. Therefore, not only is inter-cell mobility management implemented, but the inter-cell movement delay of the terminal device is reduced and beam selection during high-speed inter-cell movement is facilitated.

[0018] In one possible design of the first aspect, obtaining a measurement result for the first cell based on the first message includes measuring a reference signal of the first cell based on a physical layer measurement metric to obtain the measurement result for the first cell for the purposes of shortening measurement time, further reducing inter-cell movement delay, implementing beam selection during high-speed inter-cell movement, and helping to improve performance in high-speed movement scenarios.

[0020] According to a communication method provided in a second aspect, a network device determines a first message.

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. The network device transmits the first message to the terminal device. In this manner, not only can the terminal device be activated to measure the reference signal of the first cell, but also the measurement results can be configured to be reported in a physical layer (Layer 1) coding format. This provides a basis for the terminal device to report the measurement results to the network device, thereby allowing the terminal device to report the measurement results of the first cell in a physical layer (Layer 1) coding format to the network device in a timely and fast manner.

[0047]

[0013] Figure 1 is a schematic architecture diagram of a communication system. As shown in Figure 1, the communication system in the present application may include at least one network device and at least one terminal device, and the network device may communicate with the terminal device. In Figure 1, one network device and multiple terminals are used as an example for explanation.

[0048] The three main application scenarios of 5G NR are enhanced mobile broadband (eMBB), ultra-reliable low latency communication (uRLLC), and massive machine-type communication (mMTC). To accommodate these three application scenarios, high-frequency bands are being introduced into 5G NR to achieve larger bandwidths and higher transmission speeds. Due to the high frequency, severe fading may occur during signal transmission in space. Therefore, 5G NR uses beamforming (BF) technology to achieve good directional gain, increasing the directional output in the transmission direction and improving the signal-to-interference plus noise radio (SINR) at the receiving terminal, thereby improving system performance. Considering the trade-off between cost and performance, 5G NR typically uses hybrid beamforming (HBF) technology, which includes digital and analog beamforming.

[0049] In addition, mobility management is an important part of wireless mobile communications and can ensure that the communication link between a network device and a terminal device is not interrupted due to the movement of the terminal device. In 5G NR, mobility management is mainly performed in an inter-cell mobility manner and an intra-cell mobility manner, and measurement and reporting are the main steps of mobility management. Typically, a specific measurement and reporting process may include a network device performing a measurement configuration and a reporting configuration of the terminal device. The terminal device performs measurements on corresponding configuration resources based on the measurement configuration of the network device. After the measurement, the measurement results are reported to the network device based on the reporting configuration of the network device, thereby performing inter-cell handover and intra-cell handover based on the measurement results.

[0050] The inter-cell and intra-cell measurement and reporting procedures are different. Therefore, the protocol specifies that different frameworks are used to implement inter-cell and intra-cell mobility management: radio resource measurement (RRM) is used for inter-cell mobility management, and beam management (BM) is used for intra-cell mobility management.

[0051] With reference to Figure 2, the following will separately describe intra-cell mobility management and inter-cell mobility management using an example. For ease of explanation, in Figure 2, for example, the terminal device is a mobile phone. Route 1 and Route 2 are indicated using arrows. Cell 1 includes four transmission and reception points (TRPs), namely, TRP1, TRP2, TRP3, and TRP4. Cell 2 includes four TRPs, namely, TRP5, TRP6, TRP7, and TRP8.

[0052] As shown in Figure 2, when a terminal device moves from the position of TRP3 to the position of TRP4 on Route 1, the terminal device uses RRM to perform mobility management within Cell 1. When the terminal device moves from the position of TRP2 to the position of TRP7 on Route 2, the terminal device uses BM to perform mobility management between Cell 1 and Cell 2.

[0053] In addition, see Figure 2. When cell 1 and cell 2 belong to the same set, mobility management between cell 1 and cell 2 may also be called intra-set mobility management. When cell 1 and cell 2 do not belong to a set, mobility management between cell 1 and cell 2 may also be called inter-set mobility management. The set here may also be called a cluster, a group, or the like.

[0054] The following describes a specific embodiment in which a terminal device uses RRM to perform inter-cell mobility management.

[0055] Typically, a network device notifies a terminal device of RRM measurement and reporting configuration information using RRC layer signaling. The configuration information is used to configure the reference signal, reference signal type, measurement metric, and measured cell for the RRM measurement. For the specific parameters mentioned above, please refer to the above description. Details will not be described again here. Therefore, the terminal device performs RRM measurement based on the configuration information. RRM measurement can be divided into two parts: physical layer (Layer-1) measurement and RRC layer (Layer-3) measurement. In the physical layer (Layer-1) measurement process, the terminal device measures the reference signal corresponding to the configured measurement metric on the corresponding configuration resource to obtain the measurement result. The physical layer (Layer-1) measurement process can be used as an intermediate step of the RRC layer (Layer-3) measurement, and the measurement result can be the intermediate result of the RRC layer (Layer-3) measurement.

[0056] Next, for SSB-based measurements, the terminal device may obtain beam-level physical layer (Layer 1) measurement results for SSB resources corresponding to the SSB index of the cell corresponding to the PCI, and perform various execution operations, such as obtaining a sum value, obtaining an average value, and selecting a maximum or minimum value, on the measurement results obtained on at least one SSB resource having the same SSB index and the same physical cell identifier (PCI), in order to report the measurement results to the RRC layer (Layer 3).

[0057] Next, for CSI-RS-based measurements, the terminal device may obtain beam-level physical layer (Layer 1) measurement results for CSI-RS resources corresponding to the CSI-RS resource identifier of the cell corresponding to the PCI, and may perform various calculation operations, such as obtaining a sum value, obtaining an average value, and selecting a maximum or minimum value, on the measurement results obtained on at least one CSI-RS resource having the same CSI-RS resource identifier and PCI in order to report the measurement results to the RRC layer (Layer 3).

[0058] 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 a calculation operation on the physical layer (Layer 1) measurement results of each beam in the same cell to estimate the RRC layer (Layer 3) measurement results of the cell. Then, the terminal device needs to further perform an RRC layer (Layer 3) integration operation on the obtained cell-level RRC layer (Layer 3) measurement results.

[0059] The execution operation may be understood as a filtering operation performed by the terminal device on multiple measurement results obtained in one measurement using a physical layer (Layer 1) filter, and the integration operation may be understood as a filtering operation performed by the terminal device on measurement results obtained in multiple measurements using an RRC layer (Layer 3) filter.

[0060] In addition, based on the 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 for reporting.

[0061] In general, the protocol specifies that the terminal device must verify the reporting trigger conditions at least when a new cell measurement result is generated, and when the reporting trigger conditions are met, the terminal device must send a measurement report to the network device using RRC layer encapsulation based on the configuration information.

[0062] The configuration information is further used to configure reporting criteria such as event triggers or periodic triggers, reporting formats such as reporting cell-level measurement metrics or reporting cell-level measurement metrics and beam-level measurement metrics, types of measurement metrics, and the number of cell-level measurements to be reported and the number of beams to be reported (beam-level measurement metrics).

[0063] In conclusion, the above content is an RRM framework. A terminal device performs RRM measurements according to the measurement configuration and instructions of an RRC layer (Layer 3) command, and reports measurement reports to a network device via the RRC layer (Layer 3) according to the reporting configuration of the RRC layer (Layer 3), so that the terminal device can perform inter-cell mobility management.

[0064] The following describes a specific embodiment in which a terminal device uses a BM to perform intra-cell mobility management.

[0065] Generally, a network device notifies a terminal device of BM measurement configuration information using RRC layer (Layer 3) signaling and / or MAC layer (Layer 2) signaling and / or physical layer (Layer 1, also referred to as Layer 1) signaling. The configuration information is used to configure reference signals and measurement metrics for BM measurements. For the specific parameters mentioned above, please refer to the above description. Details will not be described again here. Therefore, the terminal device performs BM measurements based on the configuration information to obtain measurement results.

[0066] In addition, the network device notifies the terminal device of the configuration information of the BM report using RRC layer (Layer 3) signaling and / or MAC layer (Layer 2) signaling and / or physical layer (Layer 1) signaling. Therefore, when the report trigger condition is met, the terminal device needs to send the measurement report to the network device in a physical layer (Layer-1) encoding format based on the configuration information.

[0067] The configuration information is used to configure multiple reporting configurations, i.e., periodic CSI-RS based periodic reporting, periodic or semi-persistent CSI-RS based semi-persistent reporting, and periodic, semi-persistent, or aperiodic CSI-RS based aperiodic reporting, etc.

[0068] When the configuration information is used to configure periodic reporting, the terminal device may perform measurements based only on periodic CSI-RS resources, and the terminal device may send measurement reports to the network device on a physical uplink control channel (PUCCH).

[0069] When the configuration information is used to configure semi-persistent reporting, the terminal device may perform measurements based on periodic or semi-persistent CSI-RS resources, and the terminal device may transmit the measurement report to the network device on a PUCCH or a physical uplink share channel (PUSCH). When the network device transmits a medium access control sub layer (MAC, MAC-CE) command (also referred to as Layer 2, such as a MAC-customer edge (MAC-CE) command) or downlink control information (DCI) to the terminal device to activate / deactivate the terminal device for the purpose of performing semi-persistent reporting, the terminal device may transmit the measurement report to the network device on a PUSCH.

[0070] When the configuration information is used to configure aperiodic reporting, the terminal device may perform measurements based on periodic, semi-persistent, or aperiodic CSI-RS resources, and the terminal device may transmit the measurement reports on the PUSCH to the network device.

[0071] In conclusion, the above content is a BM framework. A terminal device performs BM measurements based on the measurement configuration of an RRC layer (Layer 3) command and the instructions of a MAC layer (Layer 2) and a physical layer (Layer 1) command, and reports measurement reports to a network device via the physical layer (Layer 1) based on the reporting configuration of the RRC layer (Layer 3), so that the terminal device can perform intra-cell mobility management.

[0072] Based on the above description, in the BM framework, only the relevant configuration of the serving cell is configured, and the relevant configuration of the non-serving cell is not configured, while in the RRC framework, the relevant configuration of the non-serving cell and the serving cell is configured, so the terminal device cannot perform inter-cell mobility management using the BM. In addition, although the terminal device can perform inter-cell mobility management using the RRM, the RRM measurement result is reported via the RRC layer (Layer 3), so the RRM report delay is long and beam selection during high-speed inter-cell movement cannot be performed.

[0073] To solve the above-mentioned problems, the present application provides a communication method, an apparatus, a device, and a computer storage medium. The latency of reporting measurement results via the physical layer (Layer 1) is much shorter than the latency of reporting measurement results via the RRC layer (Layer 3). A terminal device can be configured to report measurement results to a network device in a physical layer (Layer 1) coding format. In this way, inter-cell mobility latency is reduced, thereby enabling beam selection during high-speed inter-cell movement. This helps improve performance in high-speed mobility scenarios, thereby meeting service requirements for low latency and high reliability.

[0074] The following describes in detail the specific process of performing the communication method by the terminal device and the network device in FIG. 1 of the present application with reference to FIG.

[0075] 3 is a signaling flowchart of a communication method according to an embodiment of the present application. As shown in FIG. 3, the communication method of the present application may include the following steps:

[0076] S101: A network device determines a first message, the first message indicating to a terminal device to measure a reference signal of a first cell and report the configured measurement results in a physical layer coding 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. In the present application, the network device may determine the first message. The first message may not only indicate to the terminal device to measure the reference signal of the first cell, but may also configure the measurement results to be reported in a physical layer (Layer 1) coding format, to activate the terminal device to measure the reference signal of the first cell. This provides a basis 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 a physical layer (Layer 1) coding format to the network device in a timely and fast manner.

[0077] The number and type of the first message are not limited in this application. Optionally, the first 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.

[0078] For example, the network device may determine one first message based on any one of the aforementioned types of information to activate the terminal device to measure the reference signal of the first cell using the first message and configure the measurement results to be reported in a physical layer (Layer 1) coding format, which helps reduce configuration instructions for the network device.

[0079] In another example, the network device may determine the first messages based on any of a plurality of types of information to activate the terminal device to use some of the first messages to measure the reference signal of the first cell, configure measurement results for the other first messages, and report the measurement results in a physical layer (Layer 1) coding format. The design is simple and convenient.

[0080] The specific instruction format of the first message is not limited in the present application. For example, in the present application, one or more information bits (bits) in the first message may be used to activate a terminal device to measure a reference signal of the first cell and configure the measurement result. The measurement result is reported in a physical layer (Layer 1) coding format. In addition, the physical layer (Layer 1) coding format is a format applicable to coding in the physical layer (Layer 1). This is not limited in the present application.

[0081] In the present application, the first cell may include a non-serving cell of one or more terminal devices. Alternatively, the first cell may include a serving cell of one or more terminal devices and a non-serving cell of one or more terminal devices. The cell type may include a serving cell and a non-serving cell.

[0082] The serving cells may include at least one primary cell (PCell) and at least one secondary cell (SCell). The primary serving cell is a cell operating in a primary frequency band. The terminal device performs an initial connection establishment procedure or initiates a connection re-establishment procedure in the cell. In a handover process, the cell is referred to as the primary cell. The secondary serving cell is a cell operating in a secondary frequency band. Once an RRC connection is established, the secondary cell may be configured to provide additional radio resources. Cells other than the aforementioned cells are non-serving cells.

[0083] For a terminal device in RRC connected mode, if carrier aggregation (CA) is not configured, the serving cell has only one primary serving cell. If CA is configured, the serving cell may include a primary cell and a secondary cell. In this way, the terminal device can perform cell handover. For a terminal device in RRC idle mode (RRC_IDLE) or RRC inactive mode (RRC_INACTIVE), the serving cell may also be understood as the cell corresponding to the system information (SI) message received by the terminal device, and other cells are non-serving cells. Note that the cell range covered by the first cell may be configured by the network device, predefined in a protocol, or pre-stored in the terminal device. This is not a limitation in the present application.

[0084] When the cell range covered by the first cell is predefined in 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 by the network device, the network device can use multiple implementations, so that the terminal device can determine the cell range covered by the first cell.

[0085] Optionally, the network device may notify the terminal device using the first message so that the terminal device may determine the cell range covered by the first cell based on the first message to store the instruction.

[0086] The first message may be used to indicate some or all of the non-serving cells of the terminal device, or may be used to indicate some or all of the non-serving cells of the terminal device and some or all of the serving cells of the terminal device, which is not limited in this application.

[0087] Alternatively, the network device may use the fifth message to notify the terminal device, so that the terminal device can determine the cell range covered by the first cell based on the fifth message. The design is simple and convenient.

[0088] The fifth message may be used to indicate some or all of the non-serving cells of the terminal device, or may be used to indicate some or all of the non-serving cells of the terminal device and some or all of the serving cells of the terminal device, which is not limited in this application.

[0089] Alternatively, the network device may transmit the first message and the fifth message so that the terminal device can determine the cell range covered by the first cell based on the first message and the fifth message to deal with unexpected cases such as a temporary bad signal of the cell. message may be used to notify the terminal device.

[0090] For example, the terminal device may determine the intersection of the cell range determined based on the first message and the cell range determined based on the fifth message as the cell range covered by the first cell. Alternatively, the terminal device may determine the entire set of the cell range determined based on the first message and the cell range determined based on the fifth message as the cell range covered by the first cell. This is not a limitation in the present application.

[0091] The specific implementation of the first message and the fifth message is not limited. Optionally, the first message and / or the fifth message may be used to indicate the maximum number of first cells measured by the terminal device based on the first message, may be further used to indicate a cell set of the first cells measured by the terminal device based on the first message, or may further indicate the maximum number and cell set of the first cells measured by the terminal device based on the first message. This is not limited in the present application.

[0092] The network device may transmit the first message and the fifth message to the terminal device separately. The order of transmitting the first message and the fifth message is not limited. Alternatively, the network device may transmit the first message and the fifth message to the terminal device simultaneously. The number and type of the fifth message are not limited in this application. Optionally, the type of the fifth message may include at least one of RRC layer (Layer 3) information, MAC layer (Layer 2) control information (such as a MAC-CE command), or physical layer (Layer 1) dynamic control information (such as DCI). In addition, the specific indication format of the fifth message is not limited in this application. For example, in this application, the cell range covered by the first cell may be configured using one or more information bits in the fifth message.

[0093] In addition, since measurement and reporting are key steps in mobility management, the network device may further configure relevant information for measuring the reference signal of the first cell by the terminal device to configure inter-cell mobility management for the terminal device.

[0094] In some embodiments, the network device may configure relevant information for the terminal device to measure the reference signal of the first cell. Optionally, the network device may use the first message to configure relevant information for the terminal device to measure the reference signal of the first cell, or may use another message to configure relevant information for the terminal device to measure the reference signal of the first cell. Alternatively, the network device may use both the first message and another message to configure relevant information for the terminal device to measure the reference signal of the first cell. This is not a limitation in the present application.

[0095] For example, the first message may be used not only to activate the terminal device to measure the reference signal of the first cell and to configure the measurement results to be reported in a physical layer (Layer 1) coding format, but also to configure measurement-related information of the first cell, thereby reducing the configuration instructions of the network device.

[0096] In another example, a first message may be used to activate a terminal device to measure a reference signal of a first cell and configure the measurement result to be reported in a physical layer (Layer 1) coding format, and another message may be used to configure measurement-related information of the first cell. The design is simple and convenient.

[0097] In another example, a first message may be used to activate a terminal device to measure reference signals of a first cell and configure the measurement results to be reported in a physical layer (Layer 1) coding format, and the other message and the first message may be used together to configure measurement-related information of the first cell to provide the capability.

[0098] The network device may separately transmit the first message and the other message to the terminal device. The order of transmitting the first message and the other message is not limited. Alternatively, the network device may simultaneously transmit the first message and the other message to the terminal device. The number and type of the other messages are not limited in the present application. The other message and the first message may be the same type of message or different types of messages. The number and type of the other messages are not limited in the present application. Optionally, the other 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. In addition, the specific indication format of the other message is not limited in the present application. For example, in the present application, the measurement-related information of the first cell may be configured using one or more information bits in the other message.

[0099] S102: The network device sends a first message to the terminal device.

[0100] S103: The terminal device obtains a measurement result of the first cell based on the first message, and the measurement result of the first cell is used by the terminal device to perform cell selection, cell reselection, or cell handover.

[0101] In the present application, a network device may send a first message to a terminal device to activate the terminal device to measure a reference signal of a first cell and configure the terminal device to report the measurement result in a physical layer (Layer 1) coding format. Further, the terminal device may obtain the measurement result of the first cell based on the first message.

[0102] The specific representation of the measurement result of the first cell is not limited in this application. In addition, the measurement result of the first cell may be used by the terminal device to perform cell selection, cell reselection, or cell handover. Generally, when the terminal device is in RRC idle mode / RRC inactive mode, the terminal device may perform cell selection or cell reselection based on the measurement result of the first cell. When the terminal device is in RRC connected mode, the terminal device may perform cell handover based on the measurement result of the first cell.

[0103] Based on the foregoing, the latency of reporting measurement results via the physical layer (Layer 1) is shorter than the latency of reporting measurement results via the RRC layer (Layer 3). Compared with the case where the terminal device uses RRM to perform inter-cell mobility management, according to the communication method of the present application, the terminal device can timely and quickly report the measurement results of the first cell in the physical layer (Layer 1) coding format to the network device. This reduces the inter-cell movement delay of the terminal device and facilitates beam selection during high-speed inter-cell movement.

[0104] According to the communication method provided in the present application, a network device determines a first message. The first message not only indicates to a terminal device to measure a reference signal of a first cell but also reports configured measurement results in a physical layer (Layer 1) coding 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. The network device transmits the first message to the terminal device. In this manner, not only can the terminal device be activated to measure the reference signal of the first cell, but the measurement results can also be configured to be reported in a physical layer (Layer 1) coding format. This provides a basis for the terminal device to report the measurement results to the network device, allowing the terminal device to report the measurement results of the first cell in a physical layer (Layer 1) coding format to the network device in a timely and fast manner. Therefore, not only is inter-cell mobility management implemented, but the inter-cell movement delay of the terminal device is reduced and beam selection during high-speed inter-cell movement is facilitated.

[0105] Those skilled in the art may understand that in the BM framework, a terminal device performs BM measurements based on physical layer (Layer 1) measurement metrics. In the RRM framework, a terminal device performs RRM measurements based on physical layer (Layer 1) measurement metrics and RRC layer (Layer 3) measurement metrics. The measurement time based on the RRC layer (Layer 3) measurement metrics is much longer than the measurement time based on the physical layer (Layer 1) measurement metrics. The measurement metrics may be understood as performance indicators for measuring reference signals, such as RSRP, RSRQ, or SINR.

[0106] Based on this, in this application, the terminal device may measure the reference signal of the first cell based on the physical layer (Layer 1) measurement metric to shorten the measurement time, further reduce the inter-cell movement delay, and perform beam selection during high-speed inter-cell movement, thereby helping to improve performance in high-speed movement scenarios. In this way, the service requirements of low latency and high reliability are met.

[0107] The operation of measuring the reference signal of the first cell based on the physical layer (Layer 1) measurement metric by the terminal device may be configured by the network device, for example, may be indicated using the first message or another message, may be defined by a protocol, or may be selected by the terminal device, which is not limited in this application.

[0108] Based on the above description, the terminal device may perform cell selection, cell reselection, or cell handover in several embodiments. With reference to Figures 4 and 5, the following uses embodiment 1 and embodiment 2 as examples to describe a specific implementation process of performing cell selection, cell reselection, or cell handover by the terminal device in this application.

[0109] In embodiment 1, the terminal device may perform cell selection, cell reselection, or cell handover based on the decision made by the network device. In embodiment 2, the terminal device performs a decision based on the measurement result of the first cell to perform cell selection, cell reselection, or cell handover.

[0110] Embodiment 1 4 is a signaling flowchart of a communication method according to an embodiment of the present application. As shown in FIG. 4, the communication method of the present application may include the following steps:

[0111] S201: A network device determines a first message, the first message indicating to a terminal device to measure a reference signal of a first cell and report the configuration measurement result in a physical layer encoding format, wherein 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.

[0112] S202: The network device sends a first message to the terminal device.

[0113] S203: The terminal device obtains a measurement result of the first cell based on the first message, and the measurement result of the first cell is used by the terminal device to perform cell selection, cell reselection, or cell handover.

[0114] The implementations of S201, S202, and S203 are respectively similar to S101, S102, and S103 in the embodiment shown in Figure 3. Details will not be described again here in this application.

[0115] S204: The terminal device performs physical layer encoding format processing on the measurement result of the first cell based on the first message to obtain the measurement result of the first cell in a physical layer encoding format.

[0116] Since the first message is used to configure the measurement results to be reported in a physical layer (Layer 1) encoding format, the terminal device may perform physical layer (Layer 1) encoding format processing on the measurement results of the first cell based on the first message to obtain the measurement results of the first cell in the physical layer encoding format.

[0117] After receiving the instruction sent by the network device, the terminal device may report the measurement result of the first cell to the network device. The following describes a specific implementation process with reference to two specific embodiments.

[0118] In a possible embodiment, the network device may send a second message to the terminal device, and the second message indicates the terminal device to report the measurement result of the first cell to the network device, so that the terminal device reports the measurement result of the first cell according to the second message. The design is simple and convenient.

[0119] In another possible embodiment, the network device may notify the terminal device using a first message, which indicates to the terminal device to report the measurement result of the first cell to the network device, whereby the terminal device reports the measurement result of the first cell based on the first message and thereby stores the configuration instruction.

[0120] S205: The terminal device reports a third message to the network device, where the third message includes the measurement result of the first cell in a physical layer encoding format.

[0121] In the present application, the terminal device may include the measurement result of the first cell in a physical layer encoding format in a third message, thereby causing the terminal device to transmit the third message to the network device. Parameters such as the type and number of the third message are not limited in the present application. 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. In addition, the specific indication format of the third message is also not limited in the present application. For example, in the present application, the measurement result of the first cell in a physical layer encoding format may be configured using one or more information bits in the third message.

[0122] S206: The network device sends a fourth message to the terminal device, where the fourth message is obtained based on the measurement result of the first cell in a physical layer encoding format, and the fourth message indicates to the terminal device to perform cell selection, cell reselection, or cell handover.

[0123] In the present application, the network device may obtain a measurement result of the first cell in a physical layer encoding format from the received third message, and obtain a fourth message based on the measurement result of the first cell in the physical layer encoding format, the fourth message indicating to the terminal device to perform cell selection, cell reselection, or cell handover.

[0124] Parameters such as the type and number of the fourth message are not limited in this application. 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. In addition, the specific instruction format of the fourth message is not limited in this application. For example, in this application, one or more information bits in the fourth message may be used to indicate to the terminal device to perform cell selection, cell reselection, or cell handover.

[0125] S207: The terminal device performs cell selection, cell reselection, or cell handover based on the fourth message.

[0126] The fourth message may be used to indicate to the terminal device to perform cell selection, cell reselection, or cell handover, so that the terminal device may perform cell selection, cell reselection, or cell handover based on the received fourth message. For example, when the fourth message indicates to the terminal device to perform cell selection, the terminal device performs cell selection. When the fourth message indicates to the terminal device to perform cell reselection, the terminal device performs cell reselection. When the fourth message indicates to the terminal device to perform cell handover, the terminal device performs cell handover.

[0127] In addition, the fourth message may be further used to indicate a cell corresponding to cell selection, cell reselection, or cell handover performed by the terminal device. For example, the fourth message may include cell identification information, so that the terminal device selects a cell corresponding to the identification information to perform cell selection, cell reselection, or cell handover.

[0128] Embodiment 2 5 is a signaling flowchart of a communication method according to an embodiment of the present application. As shown in FIG. 5, the communication method of the present application may include the following steps:

[0129] S301: A network device determines a first message, the first message indicating to a terminal device to measure a reference signal of a first cell and report the configuration measurement result in a physical layer encoding format, wherein 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.

[0130] S302: The network device sends a first message to the terminal device.

[0131] S303: The terminal device obtains a measurement result of the first cell based on the first message, and the measurement result of the first cell is used by the terminal device to perform cell selection, cell reselection, or cell handover.

[0132] The implementations of S301, S302, and S303 are respectively similar to S101, S102, and S103 in the embodiment shown in Figure 3. Details will not be described again here in this application.

[0133] S304: The terminal device performs cell selection, cell reselection, or cell handover based on the measurement result of the first cell.

[0134] The measurement result of the first cell may indicate a performance indicator of the first cell, so that the terminal device can perform cell selection, cell reselection, or cell handover based on the measurement result of the first cell, without needing to obtain information for performing cell selection, cell reselection, or cell handover via a network device. The operation is simple and convenient, and signaling overhead is reduced.

[0135] In consideration of the fact that the measurement result of the first cell may fluctuate greatly, the terminal device may optionally obtain a first threshold value, and perform cell selection, cell reselection, or cell handover based on the measurement result of the first cell and the first threshold value, so as to reduce repeated cell selection, cell reselection, or cell handover operations performed by the terminal device, thereby reducing losses of the terminal device and mitigating the ping-pong effect to a certain extent.

[0136] For example, the terminal device may compare a difference between the measurement result of the non-serving cell and the measurement result of the serving cell based on the measurement result of the first 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 equal to or less than the first threshold, the terminal device does not perform cell selection, cell reselection, or cell handover.

[0137] The first threshold may be configured by the network device, defined in a protocol, or pre-stored in the terminal device. This is not a limitation of the present application. When the first threshold is pre-defined in a protocol or pre-stored in the terminal device, the terminal device may directly determine the first threshold. When the first threshold is configured by the network device, the network device may use multiple implementations to allow the terminal device to determine the first threshold.

[0138] Optionally, the network device may notify the terminal device using the first message so that the terminal device may determine a first threshold based on the first message to store the instruction.

[0139] Alternatively, the network device may notify the terminal device using a separate message, so that the terminal device can determine the first threshold value based on the separate message. The design is simple and convenient.

[0140] Alternatively, the network device may determine the first threshold based on the first message and the other message so as to deal with unexpected cases in which the first threshold temporarily changes. message may be used to notify the terminal device.

[0141] In conclusion, the terminal device performs inter-cell mobility management regardless of embodiment 1 or embodiment 2. It should be noted that the terminal device may perform the steps of embodiment 1, may perform the steps of embodiment 2, or may perform the steps of embodiment 1 and embodiment 2. This is not limited in the present application.

[0142] Based on the foregoing description, in some embodiments, the network device may implement the process in which the network device determines the first message in S101.

[0143] In a possible embodiment, the terminal device may send a sixth message to the network device, and the sixth message indicates whether the terminal device has the ability to measure the first cell, so that the network device can know whether the terminal device has the ability to measure the first cell based on the sixth message. Therefore, the network device determines the first message based on the actual situation and the ability of the terminal device to measure the first cell.

[0144] Parameters such as the type and number of the sixth message are not limited in this application. 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. In addition, the specific indication format of the sixth message is not limited in this application. For example, in this application, one or more information bits in the sixth message may be used to indicate whether the terminal device has the ability to measure the first cell.

[0145] In another possible embodiment, the network device may refer to the actual status of the device's network access to obtain predetermined information indicating whether the terminal device has the ability to measure the first cell, so that the network device refers to the actual status and determines the first message based on the information.

[0146] Based on the above description, the information in the first message may include multiple representation formats and is used to obtain the measurement result of the first cell. The following describes the representation formats of the information in the first message using examples.

[0147] In a possible representation, the information in the first message may include first information, which is used by the terminal device to measure a reference signal of the first cell. In other words, the terminal device may measure the reference signal of the first cell based on the first information to obtain a measurement result of the first cell.

[0148] Optionally, when the first message includes the first information, the network device may use the first message and / or another message to further trigger / activate the terminal device to perform the following process: the terminal device measures a reference signal of the first cell based on the first information to obtain a measurement result of the first cell; alternatively, the terminal device measures a reference signal of the first cell based on the first information and a physical layer (Layer 1) measurement metric to obtain a measurement result of the first cell.

[0149] The first information may be a software program executed by the terminal device to measure the reference signal of the first cell, and the specific content of the first information is not limited in the present application. 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 cells in the first cell, and configuration information of the 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 cells in the first cell and the configuration information of the beam failure recovery management of the first cell may be further used for another function, such as data transmission. Details will not be described here.

[0150] In another possible expression, the information in the first message may include second information, which indicates to the terminal device to call third information, and the third information is used to obtain measurement results of the first cell. In other words, the terminal device may call the third information indicated by the second information to obtain measurement results of the first cell.

[0151] The second information may be a corresponding software instruction for instructing the terminal device to call the third information, which may be a conventional RRM software program or a software program executed by the terminal device to measure the reference signal of the first cell.

[0152] Optionally, when the first message includes the second information, the network device may use the first message and / or another message to further trigger / activate the terminal device to perform the following process: the terminal device may retrieve third information based on the second information to obtain measurement results of the first cell, and measure reference signals of the first cell based on the third information. Alternatively, the terminal device may retrieve third information based on the second information to obtain measurement results of the first cell, and measure reference signals of the first cell based on the third information and physical layer (Layer 1) measurement metrics.

[0153] In another possible expression, the information in the first message may include fourth information, and the fourth information indicates to the terminal device to call the measurement result of the first cell. In other words, the terminal device may be indicated by the fourth information to call the measurement result of the first cell.

[0154] The fourth information may be a corresponding software instruction for instructing the terminal device to acquire measurement results of the first cell. The measurement results of the first cell may be acquired by a conventional RRM software program or a software program executed by the terminal device to measure the reference signal of the first cell, which is not limited in this application.

[0155] Optionally, when the first message includes the fourth information, the network device may use the first message and / or another message to further trigger / activate the terminal device to perform the following process: the terminal device may call and directly obtain measurement results of the first cell based on the fourth information.

[0156] It should be noted that in addition to the above-mentioned expression formats, the first message may further use any combination of the above-mentioned expression formats. In addition, the first message may alternatively be used for instructing / activating / triggering and only used to indicate to the terminal device to measure the reference signal of the first cell, whereby the measurement result of the first cell obtained by measuring the reference signal of the first cell based on the third information may be transmitted to the terminal device via the configured interface, and the terminal device obtains the measurement result of the first cell via the configured interface based on the first message. In addition, in addition to the manner in which the network device performs the configuration, any process of triggering / activating the terminal device to perform may also be defined in the protocol or may be pre-configured in the terminal device.

[0157] The other message is different from the first message, and for a specific embodiment of the other message, please refer to the above content. Details will not be described again here. In addition, the network device may use the first message or the other message to further configure each reference signal in the third information as at least one of a periodic reference signal, a semi-persistent reference signal, or an aperiodic reference signal, so that the communication method of the present application is applicable to various kinds or types of reference signals.

[0158] To reduce signaling overhead, in the present application, the network device may alternatively use the first message or another message to trigger the terminal device to report the measurement result of the first cell, or the measurement result of a non-serving cell in the first cell, or the measurement result of a serving cell in the first cell to the network device, which is not limited in the present application.

[0159] In order to standardize the reporting format of the terminal device, in this application, the network device may alternatively configure a method for reporting the measurement result using the first message or another message, and the specific implementation of the reporting method is not limited in this application.

[0160] Optionally, the reporting method is a method of reporting after performing physical layer encoding format processing on the measurement result of the first cell.

[0161] Alternatively, the reporting method is a reporting method after performing physical layer encoding format processing on the measurement result of the first cell and the indicated identity information corresponding to the measurement result of the first cell.

[0162] Alternatively, the reporting method is a method of performing physical layer encoding formatting processing on the measurement result of the first cell and the identification information of the reference signal corresponding to the measurement result of the first cell, and then reporting the result.

[0163] Alternatively, the reporting method is a method of reporting after performing physical layer encoding format processing on the measurement result of the first cell, identification information of the reference signal corresponding to the measurement result of the first cell, and identification information of the cell corresponding to the measurement result of the first cell.

[0164] Alternatively, the reporting method is a method of performing physical layer coding format processing on the measurement results of non-serving cells in the first cell before reporting.

[0165] Alternatively, the reporting method is a method of reporting after performing physical layer coding on the measurement results of non-serving cells in the first cell and the cell identification information corresponding to the measurement results of non-serving cells in the first cell.

[0166] Alternatively, the reporting method is a method of reporting after performing physical layer encoding format processing on the measurement results of non-serving cells in the first cell and identification information of reference signals corresponding to the measurement results of non-serving cells in the first cell.

[0167] Alternatively, the reporting method is a method of reporting after performing physical layer encoding format processing on the measurement results of non-serving cells in the first cell, cell identification information corresponding to the measurement results of non-serving cells in the first cell, and reference signal identification information corresponding to the measurement results of non-serving cells in the first cell.

[0168] Alternatively, the reporting method is a method of reporting after performing physical layer encoding format processing on the measurement results of the first cell, cell identification information corresponding to the measurement results of non-serving cells in the first cell, and reference signal identification information corresponding to the measurement results in the first cell.

[0169] It should be noted that the way in which the network device performs the configuration, as well as the way in which the configuration measurements are reported, may also be defined in the protocol or may be pre-configured in the terminal device.

[0170] In order to reduce signaling overhead, in the present application, the network device may alternatively configure the terminal device to perform physical layer coding on the identity information of one of the same cells, i.e., the identity information of the same cell, using the first message or another message, and the terminal device reports the identity information of the cell in the physical layer coding format to the network device once.

[0171] The specific implementation of the cell identification information is not limited in this application. Optionally, the cell identification information includes a cell ID or other information, and the other information is mapped to the cell ID. The cell ID may include, but is not limited to, a serial number, a PCI, or another form of identifier. Because there are a large number of cells, the value corresponding to the cell ID is very large. When a terminal device reports a cell ID with a large value to a network device, the cell ID may occupy multiple information bits. Therefore, the terminal device may alternatively represent the cell identification information based on other information mapped to the cell ID to reduce signaling overhead.

[0172] It should be noted that in addition to the configuration being performed by the network device, the terminal device may also perform physical layer encoding for the identity of one of the same cells, which may be defined in the protocol or may be pre-configured in the terminal device.

[0173] In addition, the terminal device may typically report the measurement result of the first cell on which physical layer coding is performed to the network device in the form of a table, a report, etc. In addition, when reporting the measurement result, the terminal device may further report parameters such as a cell index, cell identity information, measurement metrics, and reference signals to the terminal device. In the following, a table format is used as an example to describe how the terminal device reports the measurement result of the first cell on which physical layer coding is performed to the network device.

[0174] In a particular embodiment, when the first cell includes only non-serving cells of at least one terminal device, the non-serving cells include cell 1, cell 2, cell 3, and cell 4. In this case, the terminal device may report measurement results of the first cell using physical layer coding to the network device in the format shown in Table 1 or Table 2.

[0175] [Table 1]

[0176] [Table 2]

[0177] In Tables 1 and 2, the measurement result of the first cell obtained using physical layer coding includes a cell index, cell identification information (e.g., PCI), a reference signal resource indicator (e.g., synchronization signal block resource indicator (SSB RI) or channel state information reference signal resource indicator (CSI-RS resource indicator (CRI))), and a report value (i.e., the measurement result).

[0178] The difference between Table 1 and Table 2 is that Table 1 shows two indexes and two PCIs for cell 2, while Table 2 shows one index and one PCI for cell 2. In another particular embodiment, when the first cell includes a non-serving cell of at least one terminal device and a serving cell of at least one terminal device, the serving cell includes cell 0, and the non-serving cells include cell 1, cell 2, cell 3, and cell 4. In this case, the terminal device may report measurement results of the first cell using physical layer coding to the network device in the format shown in Table 3 or Table 4.

[0179] [Table 3]

[0180] [Table 4]

[0181] In Tables 3 and 4, the measurement results for the first cell obtained using physical layer coding include the cell index, cell identity (e.g., PCI), reference signal resource indication (e.g., SSB RI / CRI), and report value.

[0182] The difference between Table 1 and Table 2 is that Table 3 shows two indexes and two PCIs for cell 2, while Table 4 shows one index and one PCI for cell 2.

[0183] The report values ​​may be reported in an absolute value manner and a differential value manner. A specific reporting method is that an arbitrary report value is selected as an absolute value for reporting, and other report values ​​are reported by taking the absolute value as a reference and taking differential values ​​for reporting. In this way, the dynamic range of the report values ​​may be narrowed, the number of coding bits may be reduced, and signaling overhead may be reduced. Of course, the report values ​​may also be reported in an absolute value reporting method. A specific reporting method is to report the absolute value of any report value. In addition, the report values ​​may also be reported in a differential value reporting method. A specific reporting method is to take a preset absolute value as a reference and report differential values ​​of all report values. The preset absolute value may be configured by the network device or defined by a protocol. This is not a limitation in the present application.

[0184] In addition, in order to reduce the overhead of the cell identification information, in the present application, the cell identification information may be represented using other information mapped to the cell ID. For example, cell ID 01 is mapped to number 1, cell ID 15 is mapped to number 2, and cell ID 68 is mapped to number 3. The mapping relationship may be configured by the network device or defined in the protocol. This is not limited in the present application, and it is sufficient that the mapping relationship corresponding to the terminal device converting the cell ID to other information is the same as the mapping relationship corresponding to the network device converting other information to the cell ID.

[0185] Based on the foregoing, in a process in which a terminal device uses a BM to perform intra-cell mobility management, the terminal device performs BM measurements based on physical layer (Layer 1) measurement metrics and reports measurement reports to a network device via the physical layer (Layer 1). Therefore, in the present application, the BM framework can be appropriately used based on a configuration for measuring a reference signal of a first cell based on physical layer (Layer 1) measurement metrics and a configuration for reporting measurement results in a physical layer encoding format, and a function for obtaining measurement results of the first cell is further added based on the BM framework. In this way, inter-cell mobility management can be implemented.

[0186] In one aspect, since the information in the first message can be used to obtain measurement results of the first cell, in the present application, the information in the first message can be added to the BM framework, and the measurement results configured in the BM framework are reported to the network device via the physical layer (Layer 1). Thus, the communication method of the present application is implemented, and configuration instructions are reduced.

[0187] When the information in the first message includes the first information, the first information is added to the BM framework, so that the terminal device performs inter-cell mobility management using the BM framework to which the first information is added. Specifically, the terminal device measures a reference signal of the first cell based on the first information and a physical layer (Layer 1) measurement metric to obtain a measurement result of the first cell, and configures the measurement result of the first cell to be reported in a physical layer (Layer 1) encoding format based on the BM framework.

[0188] When the information in the first message includes second first information, the second information is added to the BM framework, so that the terminal device performs inter-cell mobility management using the BM framework to which the second information is added. Specifically, the terminal device invokes third information (e.g., an RRM framework) based on the second information, measures a reference signal of the first cell based on a physical layer (Layer 1) measurement metric based on the third information to obtain a measurement result of the first cell, and configures the measurement result of the first cell to be reported in a physical layer (Layer 1) encoding format based on the BM framework.

[0189] When the information in the first message includes fourth first information, the fourth information is added to the BM framework, so that the terminal device performs inter-cell mobility management using the BM framework to which the fourth information is added. Specifically, the terminal device is configured to retrieve the measurement result of the first cell from the RRM framework based on the fourth information, and report the measurement result in a physical layer (Layer 1) encoding format based on the BM framework.

[0190] In another aspect of the present application, an interface connected to the BM framework may be further configured in the RRM framework, so that the measurement result of the first cell obtained based on the RRM framework may be transmitted to the BM framework through this interface, and the terminal device may obtain the measurement result of the first cell from the BM framework.

[0191] In addition, in the present application, the identity information of a cell of the RRM framework may be further added to the BM framework. The cell corresponding to the identity information of the cell of the RRM framework includes a first cell, and the cell corresponding to the identity information of the cell of the RRM framework limits the number of cells added to the BM framework. In the present application, the related configuration of the cell corresponding to the identity information of the cell of the RRM framework may be fully used, so that the terminal device can perform inter-cell mobility management of the BM framework without adding additional configuration information, thereby reducing configuration instructions and unnecessary consumption.
