[0046] As described in the background art, 5G NR has proposed an early measurement mechanism. The terminal obtains the list of target frequency points to be measured and the list of physical cell identifiers (PCI list) through the Radio Resource Control (RRC) Release message or system message, and reports the measurement results respectively in the RRC setup and RRC Resume processes, and reports the measurement results subsequently, which is convenient for the base station to perform subsequent configurations such as Carrier Aggregation (CA) and Dual Connectivity (DC).

[0047] For idle terminals, refer to Figure 1, the network carries information related to early measurement configuration (e.g., PCI list) in the RRC release message. Subsequently, the terminal can initiate a two-step random access procedure: the terminal sends Message 1 (Msg1), the random access preamble (Physical Random Access Channel (PRACH) preamble), to the network; the network sends Message 2 (Msg2), the random access response, to the terminal.

[0048] The terminal can report measurement results during the RRC establishment procedure: the terminal sends Message 3 (Msg3), the RRC Setup Request, to the network; the network sends Message 4 (Msg4), the RRC Setup, to the terminal; the terminal sends Message 5 (Msg5), the RRC Setup Complete, to the network, which indicates that there are measurement results to be reported (indication of measurement result available).

[0049] The network will request the terminal to report measurement results during the UE information request reporting procedure: the network sends the RRC Security Mode Command to the terminal; the terminal sends back the RRC Security Mode complete to the network; the network sends the UE Information Request to the terminal, which includes the MR (Measurement Report) request; the terminal sends the UE Information Response to the network, which includes the cell and optional beam MR.

[0050] Then, the network sends the RRC Reconfiguration message to the terminal, and the terminal sends the RRC Reconfiguration Complete to the network.

[0051] For an Inactive terminal, refer to Figure 2, the terminal can report measurement results during the RRC Resume process: The terminal sends an RRC Resume Request to the network; the network sends an RRC Resume message to the terminal, which instructs the terminal to report a measurement report; since the security encryption can already be restored during the recovery process of the inactive state, the terminal can report measurement results in the RRC Resume Complete message of this process.

[0052] Then, the terminal switches to the RRC_CONNECTED state, the network sends an RRC Reconfiguration message to the terminal, and the terminal sends an RRC Reconfiguration Complete to the network.

[0053] In the existing early measurement mechanism, by the base station sending a frequency list, defining a timer and a validity area, that is, in a certain time range and a certain area for early measurement, so as to control the range and timing of the terminal's measurement and reduce unnecessary power consumption.

[0054] In R18, RAN4 (the working group in 3GPP responsible for formulating the technical standards for the radio frequency aspects in the terminal) enhanced the early measurement (Scell (Secondary Cell) / SCG setup (Secondary Cellgroup setup) / resume delay). In addition to sending the measurement target frequency list, a second step was added to check whether the obtained measurement results are valid during the process of establishing / resuming the connection: through a predefined timer, the results obtained within the range of this timer are valid, and at the same time, the measurement results obtained during the cell reselection process can also be reported. In addition, additional measurements are performed during the process of establishing or resuming the connection, and the ongoing measurements of the network are reported. After that, the network will request the terminal to report the measurement results.

[0055] The above-mentioned early measurement mechanism generally targets the 5G NR scenario and needs to be further enhanced to better adapt to the 6G communication scenario (or obtain better performance in the 5G NR scenario). For example, considering that the 6G network allows users to have more autonomy and the terminal can connect to multiple cells, the fixed and unique early measurement configuration for the terminal in the existing early measurement mechanism is obviously no longer suitable.

[0056] The inventors of this application have found through analysis that one of the reasons for the above technical problems is that in the prior art, when configuring measurement targets, only a single measurement target list is configured, and the measurement targets in the same list must be measured regardless of how the position of the terminal changes during measurement. However, in fact, when the terminal is in different positions, there are significant differences in the measurement results for the same measurement target. The prior art does not take into account the impact of the terminal position on the configuration of measurement targets, resulting in the inability to better enhance the early measurement mechanism in the 5G NR scenario and even less ability to adapt to the 6G communication scenario.

[0057] To solve the above technical problems, an embodiment of this application provides an early measurement method, including: receiving configuration information, where the configuration information includes at least one measurement target, and the measurement target is associated with a position; measuring the corresponding measurement target according to the current position.

[0058] Through the enhanced early measurement mechanism provided by this implementation, different measurement targets are configured according to the terminal position. The terminal combines the different measurement targets and positions configured by the network with its own current position to determine the frequency points or cells that need to be measured currently. Thus, in the non-active state or non-connected state, the terminal can accelerate the recovery of multi-cell operations through early measurement, which is beneficial to reducing the power consumption of the terminal; in the active state, the measurement mechanism can also be enhanced to reduce the terminal power consumption.

[0059] Next, some basic concepts that may be involved in the embodiments of this application will be explained.

[0060] Regarding the 6G network (6G communication, 6G network architecture): A user-centric network is a requirement in the 6G network architecture. Being user-centric enables users to define, configure, and control network functions related to the services they subscribe to. The user-centric 6G network mainly realizes the high-speed transmission requirements of users through multiple transmission reception points (TRP) or multiple access points (AP), and at the same time needs to reduce handovers to maintain continuous services.

[0061] A possible 6G network architecture is the CCU-DDU-AP architecture, where Cloud Control Unit (CCU), Distributed Data Unit (DDU), and Access Point (AP). The following are introduced in this architecture:

[0062] 1) Cloudified Control Unit: It provides the management plane and control plane functions of the network. It includes traditional control plane functions, such as system information management related to the Access Stratum (AS) / Non-Access Stratum (NAS) layer, establishment / maintenance / release of Radio Resource Control (RRC) connections, paging control, and security functions, including bearer management, mobility management, terminal measurement, report management, and NAS information transmission. The CCU also performs management plane functions in the User Centric Access Network (UCAN), such as terminal context management and AP management.

[0063] 2) Distributed Data Unit: As the anchor point of the User Plane (UP), the Distributed Data Unit manages basic user plane functions.

[0064] 3) AP: It is mainly responsible for antenna radio frequency transmission. At the same time, low-frequency TRP is used to ensure wide coverage, while high-frequency TRP is used to ensure service transmission.

[0065] For the terminal, when accessing the network, the terminal may be connected to one or more APs to receive services. The possible networking methods of existing 6G include wide coverage by low-frequency cells (APs), while high-frequency cells (APs) are used for service transmission. The frequency point cell with wide coverage can be called the main frequency point cell, as Figure 3 shown. Figure 3 In it, the filled areas with different depths represent the signal coverage ranges of each high-frequency cell / low-frequency cell.

[0066] Regarding the radio air interface state of the terminal: In 3GPP NR, the terminal has three states on the radio air interface: RRC idle state (RRC_IDLE), RRC inactive state (RRC_INACTIVE), and RRC connected state (RRC_CONNECTED). Among them, the idle state terminal has no connection with the base station and only needs to initiate location updates, cell selection and reselection processes, and receive paging regularly; the connected state terminal has a connection with the network, and the network will configure the terminal's resource block (RB) and physical layer configurations, including DC operations (divided into co-frequency or cross-frequency scenarios, with at least two cells controlled by different base stations gNB), and the network can schedule uplink and downlink data for the terminal; the inactive state terminal does not need to notify the base station when moving within a certain Radio Access Network (RAN)-based Notification Area (RNA) range, and the terminal will retain certain configurations (currently, the terminal will retain configurations such as Packet Data Convergence Protocol (PDCP) / Service Data Adaptation Protocol (SDAP), etc., and some low-layer configurations of the original serving cell (primary cell, Pcell), but will not retain low-layer SCG configurations). If the network needs to schedule the terminal or the terminal has data to send, it needs to migrate to the connected state and resume the retained configurations for data transmission.

[0067] There may be only one RRC connected state in the 6G network. In the RRC connected state, based on whether there is a stable physical layer channel, it is divided into two states: non-active and active. These two states are both sub-states of the RRC connected state.

[0068] Non-active state: That is, the terminal power-saving state. The network and the terminal mainly maintain the security context and bearer context, and can also have a complete DRB (Data Radio Bearer) configuration. There is no fixed physical layer channel between the terminal and the network, that is, the terminal does not maintain fixed active radio air interface resources with a specific DDU / TRP. When a transmission needs to be initiated, a specific DDU / TRP needs to be activated. For fast transmission, the physical layer configuration of this TRP can also be pre-configured and activated on demand.

[0069] Active state: This is the state in which the terminal can perform continuous data transmission. The user context is maintained, and the terminal keeps the user physical layer channel with the network and the active air interface resources / physical layer configuration with one or more specific DDU / TRPs. Flexible cells are formed and flexible cell management is carried out only in the active state.

[0070] To make the above objects, features, and beneficial effects of the present application more obvious and understandable, the following will describe in detail the specific embodiments of the present application with reference to the accompanying drawings.

[0071] Figure 4 It is a flowchart of an early measurement method according to the first embodiment of the present application.

[0072] This implementation scheme can be applied to the 5G NR scenario or the 6G communication scenario.

[0073] In a specific implementation, the early measurement method provided in the following steps S101 to S102 can be executed by a chip with an early measurement function in the terminal or by the baseband chip of the terminal.

[0074] The terminal executing this implementation scheme can be in the 6G non-active state or non-connected state, where the non-connected state includes the 5G RRC idle state (RRC_IDLE) and the RRC non-active state (RRC_INACTIVE). Of course, this implementation scheme can also be applied to connected state terminals.

[0075] Specifically, referring to Figure 4 , the early measurement method described in this embodiment may include the following steps:

[0076] Step S101: Receive configuration information, where the configuration information includes at least one measurement target, and the measurement target is associated with a location;

[0077] Step S102: Measure the corresponding measurement target according to the current location.

[0078] More specifically, different measurement targets can be configured according to the location of the terminal.

[0079] Further, the measurement target may be selected from at least one of the following: a frequency point list, a cell identifier list, a transmit-receive point identifier list, a wireless access point identifier list, and a transmit-receive point group identifier list. Among them, the frequency point list includes frequency point information of one or more frequency points; the cell identifier list includes identifiers of one or more cells, such as PCI identifiers; the transmit-receive point identifier list may include identifiers of one or more TRPs; the wireless access point identifier list may include identifiers of one or more APs; the transmit-receive point group identifier list may include identifiers of one or more TRP groups, where each TRP group includes one or more TRPs.

[0080] In some embodiments, one or more TRPs included in a TRP group may be determined according to the network deployment information of high-frequency APs within the signal coverage of the primary frequency point cell (also referred to as the wide coverage cell, low-frequency cell) where the terminal is located. In the non-edge area within the signal coverage of the wide coverage cell, the signal coverage ranges of adjacent co-frequency TRPs (i.e., adjacent high-frequency co-frequency APs) may not overlap; in the edge area of the signal coverage of the wide coverage cell, the signal coverage ranges of adjacent co-frequency TRPs may overlap.

[0081] Further, the configuration information may be carried by dedicated signaling. For example, it is carried by an RRC release message. Another example is that the signaling for releasing the terminal from the connected state to the inactive state in a 6G communication scenario may include the configuration information.

[0082] Alternatively, the configuration information may be carried by system messages.

[0083] In a specific implementation, the configuration information may include a first threshold, and the first threshold is associated with the primary frequency point cell. The terminal may measure the base station of the primary frequency point cell to obtain the measurement result in the primary frequency point cell.

[0084] Further, the measurement result in the primary frequency point cell may be used to characterize the position of the terminal relative to the base station. Terminals at different positions are at different distances from the base station of the primary frequency point cell, and correspondingly different measurement targets may be configured.

[0085] For example, at least one measurement target may include a first target and a second target. Among them, the distance from the first target to the base station of the primary frequency point cell is closer than the distance from the second target to the base station of the primary frequency point cell. Step S102 may specifically include: in response to the measurement result in the primary frequency point cell being greater than or equal to the first threshold, measuring the first target; in response to the measurement result in the primary frequency point cell being less than or equal to the first threshold, measuring the second target.

[0086] Further, the measurement result may be characterized based on signal quality such as RSRP and RSRQ.

[0087] In a typical application scenario, refer toFigure 5 The configuration information can configure that there are two measurement targets (the first target and the second target) within the signal coverage range of the primary frequency point cell. Among them, the first target is selected from the high-frequency APs closer to the base station of the primary frequency point cell, and the second target is selected from the high-frequency APs farther from the base station of the primary frequency point cell. Further, the configuration information can also configure a first threshold.

[0088] The terminal measures the reference signal (RS for short, which can include SSB (Synchronization Signal Block) or CSI-RS (Channel State Information Reference Signal), etc.) sent by the base station of the primary frequency point cell. If the measurement result is greater than or equal to the first threshold, it indicates that the terminal is within the area with the base station of the primary frequency point cell as the center and a radius of x (corresponding to the area circled by the dashed line in Figure 5 ), as shown in the position of terminal A in Figure 5 . Among them, the specific value of the radius x is associated with the specific value of the first threshold, and the unit of x can be meters or kilometers. At this time, the terminal uses the first target as the measurement target for early measurement.

[0089] If the measurement result is less than (or equal to) the first threshold, it indicates that the distance from the terminal to the base station of the primary frequency point cell is greater than x (corresponding to the area outside the area circled by the dashed line and inside the area circled by the solid line in Figure 5 ), as shown in the position of terminal B in Figure 5 . At this time, the terminal uses the second target as the measurement target for early measurement.

[0090] In a specific implementation, the configuration information can include multiple threshold intervals, and different threshold intervals correspond to different measurement targets. Correspondingly, step S102 can specifically include: obtaining the measurement result for the primary frequency point cell; measuring the measurement target corresponding to the threshold interval to which the measurement result belongs.

[0091] For example, the configuration information can include the following configuration: [threshold 1, threshold 2] corresponds to the first target, (threshold 2, threshold 3] corresponds to the second target, and (threshold 3, threshold 4] corresponds to the third target. Among them, the farther the distance from the base station of the primary frequency point cell, the smaller the values of threshold 1 to threshold 4.

[0092] Further, the terminal determines the corresponding measurement target according to the interval segment in which the measurement result falls. For example, if the RSRP value obtained by the terminal measuring the RS sent by the base station of the primary frequency point cell falls within (threshold 2, threshold 3], the terminal measures the second target. Another example is that if the RSRQ value obtained by the terminal measuring the RS sent by the base station of the primary frequency point cell falls within [threshold 1, threshold 2], the terminal measures the first target.

[0093] In a specific implementation, measurement targets can be configured based on TPR groups. Specifically, at least one measurement target can include multiple TRP groups. Further, the configuration information can include a second threshold, which can be understood as the trigger threshold for determining a specific TRP group as a measurement target.

[0094] Correspondingly, step S102 can specifically include: obtaining measurement results for at least one TRP; measuring the transmission and reception point groups to which the TRPs whose measurement results are higher than the second threshold belong.

[0095] For example, during the inactive state or non-connected state, the terminal normally measures neighboring cells. When the signal quality of the TRP of a certain neighboring cell is measured to be higher than the second threshold, the terminal can measure the TRP group to which the TRP belongs.

[0096] In a specific implementation, measurement targets can be accurately configured according to the terminal location and network layout. That is, different measurement targets can be configured based on the location of the terminal.

[0097] Specifically, at least one measurement target can include a third target, which is determined according to the location information of the terminal. For example, the terminal can report location information when it is in the connected state, and this action can be performed before step S101.

[0098] Further, step S102 can specifically include: measuring the third target. In other words, in this example, the network accurately configures a most suitable measurement target (i.e., the third target) according to the location information of the terminal, and the terminal directly measures this third target when performing measurements according to the configuration of the network.

[0099] In a typical application scenario, the network layout within the primary frequency point cell is as Figure 6 shown. Assume that terminal C reports location information at the illustrated position. In response to receiving the location information of terminal C, the network can configure the third target closest to the location reported by terminal C as the measurement target for terminal C. Correspondingly, terminal C performs early measurements with the third target as the measurement target.

[0100] The solution of this example can be applicable to connected terminals or terminals with low mobility during the non-connected state for measurement.

[0101] In a specific implementation, the network can configure two sets of measurement target configurations. Different measurement target configurations use different logics when determining measurement targets according to location, corresponding to different moving speeds of the terminal. When the terminal moves fast, it can determine the measurement target according to one set of measurement target configurations, and when the terminal moves slowly, it can determine the measurement target according to the other set of measurement target configurations.

[0102] Specifically, the configuration information may include a third threshold, which can be understood as the triggering threshold for the measurement target configuration adopted by the terminal for handover.

[0103] Furthermore, at least one measurement target may include the third target described in the foregoing embodiments. Step S102 may specifically include: measuring the third target in response to the moving speed being lower than or equal to the third threshold.

[0104] Furthermore, at least one measurement target may include a fourth target, which is associated with the measurement results in the primary frequency point cell and / or neighboring cells. Correspondingly, step S102 may specifically include: measuring the fourth target in response to the moving speed being higher than or equal to the third threshold.

[0105] That is to say, when the terminal's moving speed is slow, it directly measures the third target configured by the network according to the positioning information reported by the terminal. Specifically, the network configures the third target in the terminal connection state according to the terminal's location. After the terminal migrates from the connection state to the non-connection state or the non-active state, the third target is retained as the measurement target for early measurement; or after the network migrates the terminal from the connection state to the non-connection state or the non-active state, the third target is configured, and the terminal uses the third target as the measurement target for early measurement. When the terminal's moving speed becomes faster, it switches to the fourth target configured according to the measurement results in the primary frequency point cell or neighboring cells. In one implementation, when the terminal's moving speed is greater than a certain threshold (for example, the third threshold), it switches to the fourth target, and this threshold can be implemented through network configuration or through a predefined method.

[0106] In some embodiments, the fourth target may include the first target / second target described in the foregoing embodiments. For example, when the terminal reports positioning information in the connection state, the configuration information sent by the network to the terminal may include: a third threshold, a third target (for example, it can be the TRP closest to the positioning location of the terminal), a first target (for example, it can be the TRP with a relatively light current load in the primary frequency point cell and relatively close to the base station of the primary frequency point cell), a second target (for example, it can be the TRP with a relatively light current load in the primary frequency point cell and relatively far from the base station of the primary frequency point cell), and a first threshold.

[0107] The terminal measures the third target during the period when its own moving speed is lower than the third threshold, and reports the measurement results according to the early measurement mechanism subsequently.

[0108] If the terminal's moving speed increases to above the third threshold, it then selects the first target or the second target for measurement according to the comparison result between the measurement result in the primary frequency point cell and the first threshold.

[0109] In some embodiments, the fourth target may include the multiple TRP groups described in the above embodiments. For example, when the terminal reports positioning information in the connected state, the configuration information sent by the network to the terminal may include: a third threshold, a third target (which may be, for example, the TRP closest to the positioning location of the terminal), multiple TRP groups, and a second threshold.

[0110] Reference Figure 7 , at time t1, the moving speed of the terminal is lower than the third threshold. At this time, the terminal measures the third target and reports the measurement result according to the early measurement mechanism subsequently.

[0111] If the terminal moves at high speed after time t1 and moves to the position as shown in Figure 7 . At this time, the terminal no longer measures the third target, but instead selects, according to the neighbor cell measurement result, the TRP group to which the TRP (for example, the fourth target shown in Figure 7 ) whose measurement result is greater than the second threshold belongs for measurement.

[0112] In a specific implementation, the early measurement method described in this implementation solution may further include the step of: after restoring connection or data transmission, reporting the measurement result of the measurement target associated with the current location. This step may be executed after step S102.

[0113] Specifically, the terminal may move continuously / discontinuously during the non-connected state or non-active state. During this period, the terminal continuously executes the steps described in the above embodiments to measure the corresponding measurement target according to its own position. After restoring connection or data transmission, the terminal may preferably report the measurement report of the measurement target corresponding to the current location.

[0114] In a variant, the early measurement method described in this implementation solution may further include the step of: after restoring connection or data transmission, reporting the latest measurement result obtained within the most recent preset time period. This step may be executed after step S102. Specifically, it may be combined with the enhanced mechanism for early measurement in R18. After restoring connection or data transmission, report the measurement result of the measurement target associated with the current location and whose acquisition time does not exceed the timer range.

[0115] Thus, this implementation solution provides an enhanced early measurement mechanism, configures different measurement targets according to the terminal location, and the terminal determines the frequency band or cell that needs to be measured currently based on the different measurement targets and location configured by the network and its own current location. Thus, in the non-active state or non-connected state, the terminal can accelerate the restoration of multi-cell operations through early measurement, which is beneficial to reducing the power consumption of the terminal; in the active state, the measurement mechanism can also be enhanced to reduce the terminal power consumption.

[0116] Figure 8 is a flowchart of an early measurement method according to the second embodiment of the present application.

[0117] This implementation scheme can be applied to the 5G NR scenario or the 6G communication scenario.

[0118] In specific implementation, the communication method provided in the following steps S201 to S202 can be executed by a chip with communication function in the network device or by the baseband chip of the network device. The network device may include a base station, such as the base station of the primary frequency point cell.

[0119] Specifically, referring to Figure 8 , the method for early measurement in this embodiment may include the following steps:

[0120] Step S201: Send configuration information, where the configuration information includes at least one measurement target, and the measurement target is associated with a location;

[0121] Step S202: Receive a measurement report.

[0122] Those skilled in the art understand that steps S201 to S202 can be regarded as execution steps corresponding to steps S101 to S102 in the above Figure 4 shown embodiment, and the two are complementary in specific implementation principles and logics. Therefore, the explanations of the terms involved in this embodiment can refer to the relevant descriptions in the Figure 4 shown embodiment, which will not be elaborated here.

[0123] In a specific embodiment, the configuration information further includes a first threshold, and the at least one measurement target includes a first target and a second target. If the measurement result in the primary frequency point cell is greater than or equal to the first threshold, the measurement report received in step S202 is the measurement result for the first target; otherwise, the measurement report received in step S202 is the measurement result for the second target.

[0124] In a specific embodiment, the configuration information further includes multiple threshold intervals, and different threshold intervals correspond to different measurement targets. Correspondingly, the measurement target of the measurement report received in step S202 corresponds to the threshold interval to which the measurement result of the primary frequency point cell belongs.

[0125] In a specific implementation, the at least one measurement target includes multiple transmit-receive point groups and a second threshold. Correspondingly, the measurement target of the measurement report received in step S202 is the transmit-receive point group to which the transmit-receive point with a measurement result higher than the second threshold belongs.

[0126] In a specific implementation, before performing step S201, this implementation may further include the step of receiving positioning information. The at least one measurement target configured in step S201 includes a third target, and the third target is determined according to the positioning information of the terminal. Correspondingly, the measurement report received in step S202 is the measurement result for the third target.

[0127] In a specific implementation, the configuration information further includes a third threshold, and the at least one measurement target includes: a third target, which is determined according to the positioning information of the terminal; a fourth target, which is associated with the measurement results in the primary frequency point cell and / or neighboring cells. Correspondingly, according to the moving speed of the terminal, the measurement report received in step S202 is the measurement result for the third target or the fourth target.

[0128] In a specific implementation, step S202 may specifically include the step of receiving the measurement results for the measurement targets associated with the current location reported by the terminal after resuming connection or data transmission.

[0129] Alternatively, step S202 may specifically include the step of receiving the latest measurement results obtained within a preset period recently reported by the terminal after resuming connection or data transmission.

[0130] In a specific implementation, after step S202, the network may continue to execute subsequent steps related to the early measurement mechanism, such as performing an RRC reconfiguration process according to the measurement results reported by the terminal, so that the terminal can accelerate the resumption of CA or DC operations.

[0131] Thus, the network configures different measurement targets according to the terminal location, so that the terminal can autonomously and accurately determine appropriate measurement targets for measurement according to the current location.
