Description

Technical Field

[0001] The present application relates to the field of communication technology, and in particular to a measurement configuration method, a base station and a storage medium. Background Art

[0002] In a mobile communication network, before a user equipment (UE) performs a cell handover, a source base station needs to perform measurement configuration on the UE. Based on the measurement configuration, the UE performs cell measurement and obtains a measurement report. Thus, the source base station can decide whether the UE performs a cell handover based on the measurement report.

[0003] In the related art, the source base station usually adopts the L1 / L2-Triggered mobility (LTM) measurement configuration method triggered by layer 1 (layer1, L1) and layer 2 (layer2, L2), and performs LTM measurement configuration on the UE through L1 and L2 transmission information. However, the LTM measurement configuration method only supports periodic reporting, non-periodic reporting and semi-continuous reporting, which introduces unnecessary resource overhead when the UE performs measurement reporting, resulting in a waste of communication resources. Summary of the invention

[0004] The present application provides a measurement configuration method, a base station and a storage medium to solve the problem that unnecessary resource overhead is introduced when UE performs measurement reporting, resulting in waste of communication resources, thereby achieving the purpose of saving communication resources.

[0005] In a first aspect, the present application provides a measurement configuration method, including:

[0006] The first network device sends first information to the terminal device, where the first information includes one or more measurement configuration information and one or more first identifiers corresponding to the one or more measurement configuration information, respectively, where the measurement configuration information is used to configure the terminal device to perform layer 1 measurement on the mobility LTM candidate cell triggered by layer 1 / layer 2, and to configure an event that triggers the terminal device to send a layer 1 measurement report;

[0007] The first network device receives a layer 1 measurement report sent by a terminal device. The layer 1 measurement report is obtained by the terminal device by performing layer 1 measurement on the LTM candidate cell according to the first information after completing uplink synchronization and downlink synchronization with the LTM candidate cell. The layer 1 measurement report carries a measurement identifier so that the first network device can obtain information about the event that triggers the terminal device to send the layer 1 measurement report. The measurement identifier includes at least the first identifier.

[0008] Through the measurement configuration method provided in the first aspect, the first network device sends first information to the terminal device, the first information includes one or more measurement configuration information, and one or more first identifiers corresponding to the one or more measurement configuration information, the measurement configuration information is used to configure the terminal device to perform layer 1 measurement on the LTM candidate cell, and to configure the event that triggers the terminal device to send a layer 1 measurement report, so that through the measurement configuration information, the first network device can configure the terminal device to perform layer 1 measurement, and configure the event that triggers the terminal device to perform layer 1 measurement reporting, so that the terminal device can support layer 1 measurement while also performing layer 1 measurement reporting based on event triggering. The first network device receives the layer 1 measurement report sent by the terminal device, the layer 1 measurement report is obtained by the terminal device performing layer 1 measurement on the LTM candidate cell according to the first information when the uplink synchronization and downlink synchronization with the LTM candidate cell are completed, thereby avoiding the delay introduced by the measurement reporting through the RRC message and avoiding unnecessary reporting behavior, thereby saving communication resources.

[0009] In addition, the layer 1 measurement report carries a measurement identifier so that the first network device can obtain information about the event that triggers the UE to send the layer 1 measurement report. The measurement identifier includes at least the first identifier. By adding the first identifier in the layer 1 measurement report, when the first network device receives the layer 1 measurement report, it can directly search for the measurement configuration information corresponding to the triggering behavior of this measurement reporting in the first information according to the first identifier, thereby being able to obtain the relevant configuration of the event that triggers this measurement reporting behavior. The UE does not need to send the relevant configuration of the event in the measurement configuration information in the layer 1 measurement report to the first network device again, further saving communication resources.

[0043] In this application, "at least one" means one or more, and "plurality" means two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the associated objects before and after are in an "or" relationship. "At least one of the following" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c alone can represent: a, b, c, a and b, a and c, or a, b, and c, where a, b, and c can be single or multiple. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0044] The directions or positional relationships indicated by terms such as "center", "longitudinal", "lateral", "up", "down", "left", "right", "front", and "back" are based on the directions or positional relationships shown in the accompanying drawings and are only for the convenience of describing the present application and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0045] The terms "connected" and "connected" should be understood in a broad sense. For example, the "connected" or "connected" of a circuit structure can refer to not only physical connection, but also electrical connection or signal connection. For example, it can be directly connected, that is, physically connected, or indirectly connected through at least one intermediate element, as long as the circuit is connected, or it can be the internal connection of two elements; signal connection can refer to signal connection through a circuit or through a media medium, such as radio waves. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0046] In conventional technology, there are various measurement configuration methods.

[0047] Method 1, layer 3 (layer, L3) measurement configuration method.

[0048] The source base station sends the L3 measurement configuration to the UE via a radio resource control reconfiguration (RRC Reconfiguration) message.

[0049] Among them, the L3 measurement configuration includes measurement object configuration and L3 measurement reporting configuration. The measurement object configuration is used to configure the measurement object of the UE, and the L3 measurement reporting configuration is used to configure the reporting criteria for the UE to report the L3 measurement report to the source base station, that is, to configure the reporting method by which the UE reports the L3 measurement report to the source base station.

[0050] Specifically, the methods of reporting the L3 measurement report include periodic reporting, aperiodic reporting, semi-continuous reporting and event-triggered reporting.

[0051] Among them, for event-triggered reporting, the source base station can configure an event in each L3 measurement reporting configuration, and the event is used for UE reporting evaluation, that is, the UE can report the L3 measurement report to the source base station according to the event trigger.

[0052] Based on this, the UE performs L3 measurement according to the L3 measurement configuration, obtains an L3 measurement report, and sends the L3 measurement report to the source base station through a radio resource control (RRC) message according to the L3 measurement reporting configuration.

[0053] Method 2, LTM measurement configuration method.

[0054] The source base station sends the LTM measurement configuration to the UE via a radio resource control reconfiguration (RRC Reconfiguration) message.

[0055] The LTM measurement configuration includes synchronization signal and physical broadcast channel block (SSB) resource configuration and L1 measurement reporting configuration.

[0056] The SSB resource configuration is used to configure the UE to perform L1 measurement on the SSB resources of the LTM candidate cell according to the serving cell configuration (Serving cell Config) to obtain an L1 measurement report. The L1 measurement report configuration is used to configure the reporting method by which the UE reports the L1 measurement report to the source base station.

[0057] Specifically, the manner of reporting the L1 measurement report includes periodic reporting, aperiodic reporting and semi-continuous reporting.

[0058] Based on this, the UE performs L1 measurement on the LTM candidate cell according to the LTM measurement configuration, obtains an L1 measurement report, and sends the L1 measurement report to the source base station through the channel state information report (CSI-Report) framework according to the L1 measurement reporting configuration.

[0059] In the above method 1, the source base station allows the UE to send an L3 measurement report to the source base station through an RRC message through the L3 measurement configuration. However, the delay of transmitting the RRC message is relatively large.

[0060] In the above method 2, the source base station allows the UE to measure SSB resources and report through the CSI-Report framework through the LTM measurement configuration, which can avoid the delay introduced by the measurement reporting through the RRC message. However, the method of reporting L1 measurement reports configured in the LTM measurement configuration only includes periodic reporting, non-periodic reporting and semi-continuous reporting. These reporting methods will cause unnecessary reporting behavior of the UE, thereby introducing unnecessary resource overhead and causing waste of communication resources.

[0061] Based on the above problems, the present application provides a measurement configuration method, apparatus, base station, electronic device, computer storage medium, computer program product and chip. The first network device adds an event for configuring a trigger for the UE to send an L1 measurement report in the measurement configuration, thereby enabling the UE to perform L1 measurement on the LTM candidate cell and perform event-triggered reporting, which not only avoids the delay introduced by measurement reporting through RRC messages, but also avoids unnecessary reporting behavior, thereby saving communication resources.

[0062] The measurement configuration method provided in the present application can be applicable to various communication systems, and the communication system can be a fourth generation mobile communication system (the 4th generation mobile communication system, 4G), a fifth generation mobile communication technology (5G) new radio (New Radio, NR) system or a future communication system, and can also be various other wireless communication systems, such as: a narrowband Internet of Things (NB-IoT) system, a global system of mobile communication (GSM), an enhanced data rate for GSM evolution (EDGE) system, a wideband code division multiple access (WCDMA) system, a code division multiple access 2000 (CDMA2000) system, a time division synchronous code division multiple access (TD-SCDMA) system, a general packet radio service (GPRS) system, a long term evolution (LTE) system, and a LTE frequency division duplex (FDR) system.

The network device may be used to convert received air frames to and from IP packets, and act as a router between the wireless terminal and the rest of the access network, wherein the rest of the access network may include an Internet Protocol (IP) network. The network device may also coordinate attribute management of the air interface. For example, the network device can be a backpack base station, a satellite, a drone, a base station (base transceiver station, BTS) in global system of mobile communication (GSM) or code division multiple access (CDMA), a base station (NodeB, NB) in wideband code division multiple access (WCDMA), an evolutionary node B (eNB or eNodeB) in long term evolution (LTE), or a terminal or relay station or access point that performs the base station function in V2X (vehicular to everything), device-to-device (D2D), and machine-to-machine (M2M) communications, or a base station in a 5G mobile communication system, such as gNB, etc., or a base station in a 6G mobile communication system, without limitation here.

[0065] The measurement configuration method provided in the embodiment of the present application is described in detail below with reference to the accompanying drawings.

[0066] See also Figure 1 , Figure 1 This is a signaling interaction diagram of a measurement configuration method provided in an embodiment of the present application. Figure 1 As shown, the measurement configuration method provided by the present application may include:

[0067] S101. A first network device sends first information to a UE.

[0068] Correspondingly, the UE receives the first information sent by the first network device.

[0069] The first network device is a network device currently accessed by the UE, and the first network device can provide business services for the UE.

[0070] The first information includes one or more measurement configuration information.

[0071] The measurement configuration information is used to configure the UE to perform L1 measurement on the LTM candidate cell, and to configure an event that triggers the UE to send an L1 measurement report.

[0072] Among them, the LTM candidate cell is determined by the first network device according to the L3 measurement report. When the UE initially accesses the first network device, the first network device performs L3 measurement configuration on the UE. Thus, the UE can perform periodic or non-periodic L3 measurements on neighboring cells and serving cells, obtain L3 measurement results, and generate an L3 measurement report to send to the first network device. The first network device can determine the cells suitable for L1 measurement based on the L3 measurement report, and determine these cells as LTM candidate cells.

[0073] In some examples, the first network device may determine, based on the L3 measurement report, a cell whose L3 measurement result is greater than a preset threshold as a cell suitable for L1 measurement, that is, as an LTM candidate cell.

[0074] Specifically, configuring the UE to perform L1 measurement on the LTM candidate cell may include: the first network device configures the UE with measurement resources for L1 measurement and reporting content and reporting amount for L1 measurement reporting through measurement configuration information. L1 measurement reporting refers to the UE sending an L1 measurement report to the first network device.

[0075] The measurement resources refer to SSB resources or Channel State Information-Reference Signal (CSI-RS) resources of the LTM candidate cells that can be used for L1 measurement.

[0076] The first network device may inform the UE, through measurement configuration information, of which SSB resources or CSI-RS resources of the LTM candidate cell need to perform L1 measurement.

[0077] The reporting content refers to the measurement result that needs to be sent to the first network device when the UE performs L1 measurement reporting.

[0078] After performing L1 measurement on the LTM candidate cells, the UE obtains the measurement results corresponding to each LTM candidate cell. The first network device can configure which part of the multiple measurement results needs to be reported to the first network device when the UE triggers L1 measurement reporting through measurement configuration information.

[0079] The reporting amount refers to the measurement value of the parameter that the UE needs to measure and report when performing L1 measurement on the LTM candidate cell and sending the L1 measurement report.

[0080] The parameters include reference signal receiving power (RSRP), reference signal received quality (RSRQ) and signal-to-noise and interference ratio (SINR). The first network device can select at least one parameter from the aforementioned parameters and configure it to the UE through measurement configuration information. Based on the measurement configuration information, the UE performs L1 measurement on the LTM candidate cell to obtain the measurement value of the parameter.

[0081] Based on this, the first network device may configure the UE to perform corresponding L1 measurements on the LTM candidate cells through the measurement configuration information.

[0082] The event that triggers the UE to send the L1 measurement report may be at least one of an A2 event, an A3 event, an A4 event, an A5 event, and an A6 event.

[0083] Taking the A2 event as an example, the first network device configures the A2 event in the measurement configuration information, and the A2 event indicates that the signal quality of the serving cell is greater than the threshold value. The first network device can configure the UE through the measurement configuration information to trigger the UE's measurement reporting behavior based on the A2 event after performing L1 measurement, that is, to send an L1 measurement report to the first network device.

[0084] Based on this, the first information includes one or more measurement configuration information, and the first network device sends the first information to the UE, thereby configuring the measurement resources for the UE to perform L1 measurement, as well as the reporting content and report amount of the L1 measurement report through the measurement configuration information, and configuring the event that triggers the UE to send the L1 measurement report, so that the UE can perform L1 measurement on the LTM candidate cell and trigger the L1 measurement reporting behavior based on the event.

[0085] The first network device may configure one or more events to the UE through the first information.

[0086] The first network device can configure one event for the UE through one measurement configuration information, and can also configure multiple events for the UE through one measurement configuration information. Of course, the first network device can also configure multiple events for the UE by configuring multiple measurement configuration information in the first information and configuring one event in one measurement configuration information. This application does not limit this.

[0087] When the first network device configures multiple events to the UE, the measurement resources, reporting contents, and reporting quantities corresponding to the multiple events may be the same or different.

[0088] Among them, when the first network device configures multiple measurement configuration information in the first information and configures multiple events to the UE in a manner where one measurement configuration information includes one event, the events included in each of the multiple measurement configuration information may be the same or different.

[0089] For example, the first information includes measurement configuration information A, measurement configuration information B, and measurement configuration information C. The measurement configuration information in the first information may be as shown in the following Table 1:

[0090] Table 1

[0091] Measurement configuration information A SSB Resource 1 Report content x RSRP measurement value A2 event, A3 event Measurement configuration information B SSB Resource 1 Report content RSRP measurement value A2 Event Measurement configuration information C SSB Resource 2 Report content x RSRQ measurement A2 Event

[0092] As shown in Table 1, measurement configuration information A and measurement configuration information B configure the same resources, report different contents, report the same amount, and have different events. Measurement configuration information A and measurement configuration information C configure different resources, report the same contents, report different amounts, and have different events. Measurement configuration information B and measurement configuration information C configure different resources, report the same contents, report different amounts, and have the same events.

[0093] As shown in Table 1, the first network device may configure two events for the UE through measurement configuration information A, and configure one event for the UE through measurement configuration information B and measurement configuration information C.

[0094] In addition to the measurement configuration information, considering that the first network device receives the L1 measurement report sent by the UE, it may not be able to distinguish which measurement configuration information triggered the measurement reporting behavior of the UE and sent the L1 measurement report to the first network device, resulting in the first network device being unable to instruct the UE to perform correct cell switching.

[0095] Based on this, the first information also includes one or more measurement configuration information corresponding to the one or more first identifiers respectively.

[0096] The first identifier is used to mark the measurement configuration information.

[0097] Thus, the first network device adds a first identifier corresponding to the measurement configuration information in the first information, so that when the UE reports the measurement, it can put the first identifier into the L1 measurement report and send it to the first network device. Then, when the first network device receives the L1 measurement report, it can determine based on the first identifier which measurement configuration information the UE uses to generate and send the L1 measurement report, so that the first network device can correctly instruct the UE to perform cell switching according to the L1 measurement report.

[0098] Among them, there are multiple situations for the first information.

[0099] In some examples, the first information includes a measurement configuration information and a first identifier, the first identifier is used to mark the measurement configuration information, the first network device can configure the UE to perform L1 measurement on the LTM candidate cell through the measurement configuration information, and the UE can perform L1 measurement through the measurement configuration information.

[0100] The structure of the first information may be as shown in Table 2 below:

[0101] Table 2

[0102]

[0103] As shown in Table 2, the first network device sends the first information to the UE, so that the UE performs L1 measurement and L1 measurement reporting according to the measurement configuration information A.

[0104] In other examples, the first information includes multiple measurement configuration information and multiple first identifiers, the first identifiers correspond one-to-one to the measurement configuration information, and the multiple first identifiers are used to identify multiple measurement configuration information respectively. The first network device can configure the UE to perform L1 measurement on the LTM candidate cell through the multiple measurement configuration information in sequence, and the UE can perform L1 measurement through the multiple measurement configuration information respectively.

[0105] Taking the case where the first information includes three pieces of measurement configuration information as an example, the structure of the first information may be as shown in Table 3 below:

[0106] Table 3

[0107]

[0108] As shown in Table 3, the first network device sends the first information to the UE, so that the UE can perform L1 measurement and L1 measurement reporting according to the measurement configuration information A, the measurement configuration information B and the measurement configuration information C respectively.

[0109] The first information may be carried in an RRC reconfiguration message, that is, the first network device may send the first information to the UE via the RRC reconfiguration message.

[0110] The RRC reconfiguration message includes an LTM report configuration r19 IE (LTM-ReportConfig_r19 IE) field, where IE is an information element (IE), so that the measurement configuration information can be carried in the LTM-ReportConfig_r19 IE field.

[0111] Among them, the first information also includes the RRC underlying configuration of the LTM candidate cell, and the RRC underlying configuration can be carried in the RRCreconfiguration message, so that the first network device sends the RRC underlying configuration of the LTM candidate cell to the UE through the RRC reconfiguration message, so that the UE can perform L1 measurement on the LTM candidate cell.

[0112] The first identifier can be configured in a variety of ways.

[0113] In some examples, the RRC reconfiguration message also includes an LTM-CSI report configuration identifier r19 (LTM-CSI-ReportConfigId-r19) field, and the first identifier can be carried in the RRC reconfiguration message.

[0114] In some other examples, the first identifier and the measurement configuration information may be carried together in the LTM-ReportConfig_r19 IE field.

[0115] Based on this, the first network device sends the first information to the UE, so that the UE can be configured to perform L1 measurement on the LTM candidate cell through the first information, and the UE can be configured to perform L1 measurement reporting based on event triggering, so that the UE can support L1 measurement while also performing L1 measurement reporting based on event triggering, thereby avoiding unnecessary reporting behavior and introducing unnecessary resource overhead, thereby saving communication resources.

[0116] S102. The UE performs L1 measurement on the LTM candidate cell according to the first information and obtains an L1 measurement report.

[0117] Specifically, the UE needs to perform L1 measurement on the LTM candidate cell according to the first information and generate an L1 measurement report after completing uplink synchronization and downlink synchronization with the LTM candidate cell.

[0118] Among them, L1 measurement includes L1-SSB measurement and L1-CSI-RS measurement.

[0119] L1-SSB measurement means measuring the SSB resources of the LTM candidate cell, and L1-CSI-RS measurement means measuring the CSI-RS resources of the LTM candidate cell.

[0120] Among them, the UE can perform L1 measurement on the LTM candidate cell based on the measurement resources for the UE to perform L1 measurement configured by the measurement configuration information, and generate an L1 measurement report based on the reporting content, report amount and event triggering the L1 measurement reporting behavior configured by the measurement configuration information.

[0121] For example, the LTM candidate cells include cell A, cell B and cell C. Available SSB resources are configured for the UE in the measurement configuration information. The UE performs L1 measurement on the SSB resources of cell A, cell B and cell C based on the SSB resources, and obtains multiple measurement results corresponding to each cell. The measurement results may include the RSRP measurement value, RSRQ measurement value and SINR measurement value of the cell.

[0122] The measurement configuration information also configures the UE that the event triggering the L1 measurement report is an A4 event, the reporting content of the L1 measurement report is: the measurement results of cell A and cell C, and the reporting quantity of the L1 measurement report is: RSRP measurement value and SINR measurement value.

[0123] The A4 event indicates that the signal quality of the neighboring cells is greater than the threshold value. The neighboring cells are cells A and C.

[0124] After performing L1 measurement and obtaining the measurement results, the UE can determine the signal quality of the neighboring cell based on the measurement results, such as the RSRP measurement value, RSRQ measurement value, and SINR measurement value in the measurement results, and judge whether the signal quality of the neighboring cell is greater than the threshold value. When the signal quality of the neighboring cell is greater than the threshold value, the UE is triggered to perform L1 measurement reporting.

[0125] Therefore, the UE generates an L1 measurement report according to the RSRP measurement values ​​and SINR measurement values ​​corresponding to cell A and cell C respectively.

[0126] The L1 measurement report carries a measurement identifier, so that the first network device can obtain information about the event that triggers the UE to send the L1 measurement report.

[0127] The measurement identifier at least includes a first identifier.

[0128] In this way, the UE can send the first identifier and the L1 measurement report to the first network device at the same time by adding the first identifier in the L1 measurement report. When the first network device receives the L1 measurement report, it can directly search the first information for the measurement configuration information corresponding to the measurement reporting behavior that triggers the measurement reporting behavior based on the first identifier, thereby being able to obtain the measurement resources, reporting content, reporting amount, and related parameters of the event that triggers the measurement reporting behavior. The UE does not need to send the measurement resources, reporting content, reporting amount, and related parameters of the event configured in the measurement configuration information in the L1 measurement report to the first network device again, thereby saving communication resources.

[0129] S103. The UE sends an L1 measurement report to the first network device.

[0130] Correspondingly, the first network device receives the L1 measurement report sent by the UE.

[0131] Based on this, the first network device can obtain the L1 measurement result of the UE on the LTM candidate cell according to the L1 measurement report, so as to perform cell switching according to the L1 measurement result.

[0132] In an embodiment of the present application, a first network device sends a first message to a UE, the first message including one or more measurement configuration information, and one or more first identifiers corresponding to the one or more measurement configuration information, respectively. The measurement configuration information is used to configure the UE to perform layer 1 measurement on a mobility LTM candidate cell triggered by layer 1 / layer 2, and to configure an event that triggers the UE to send a layer 1 measurement report, so that through the measurement configuration information, the first network device can configure the UE to perform L1 measurement, and configure the event that triggers the UE to perform L1 measurement reporting, so that the UE can support L1 measurement while also performing L1 measurement reporting based on event triggering. The first network device receives a layer 1 measurement report sent by the UE, and the layer 1 measurement report is obtained by the UE performing layer 1 measurement on the LTM candidate cell according to the first information when the UE completes uplink synchronization and downlink synchronization with the LTM candidate cell, thereby avoiding the delay introduced by measurement reporting through RRC messages and avoiding unnecessary reporting behavior, thereby saving communication resources.

[0133] In addition, the layer 1 measurement report carries a measurement identifier so that the first network device can obtain information about the event that triggers the UE to send the layer 1 measurement report. The measurement identifier includes at least the first identifier. By adding the first identifier in the layer 1 measurement report, when the first network device receives the layer 1 measurement report, it can directly search for the measurement configuration information corresponding to the triggering behavior of this measurement reporting in the first information according to the first identifier, thereby being able to obtain the relevant configuration of the event that triggers this measurement reporting behavior. The UE does not need to send the relevant configuration of the event in the measurement configuration information in the layer 1 measurement report to the first network device again, further saving communication resources.

[0134] Based on the above exemplary description, various situations in which the first network device performs L1 measurement configuration for the UE through the first information are described in detail below.

[0135] Case 1: The first network device configures only one event in one measurement configuration information.

[0136] In case 1, the measurement configuration information includes first configuration information, and the first configuration information may include an event configuration and a second identifier corresponding to the event configuration.

[0137] The first configuration information is used to configure an event that triggers the UE to send an L1 measurement report. The event configuration is used to configure a first event that triggers the UE to send an L1 measurement report.

[0138] Among them, the event configuration is used to configure the UE with the event-related parameters such as the threshold (Threshold), initialization report (Report On Leave), hysteresis (hysteresis), trigger time (Time To Trigger), compensation (Offset) and allowed cell list (use Allowed Cell List) corresponding to the event.

[0139] The first network device may add a new LTM event trigger configuration (LTM-Event-Trigger-Config IE) field in the LTM-ReportConfig_r19 IE, so that the first configuration information may be carried in the LTM-Event-Trigger-Config field.

[0140] When the first information includes multiple pieces of measurement configuration information, the measurement resources, reporting contents and reporting quantities corresponding to the event configurations in the multiple pieces of measurement configuration information may be the same or different.

[0141] The second identifier is used to identify the event configuration, and the first network device can obtain relevant parameters corresponding to the event configuration according to the second identifier.

[0142] When the first configuration information includes an event configuration, the first network device can only configure a first event to the UE through one measurement configuration information. At this time, the first identifier corresponding to the measurement configuration information is one-to-one corresponding to the first event, that is, after receiving the L1 measurement report, the first network device can obtain the relevant parameters of the only first event in the measurement configuration information corresponding to the first identifier according to the first identifier in the L1 measurement report.

[0143] Taking the example that the first network device configures the A2 event and the A3 event for the UE at the same time through the first information, the code of the first information may be as follows:

[0144]

[0145]

[0146] Based on the above code, it can be known that the first information includes two measurement configuration information, one measurement configuration information only includes one event configuration, the A2 event and the A3 event are respectively configured in the two measurement configuration information, and different events have their own corresponding measurement resources, reporting content and reporting amount. The A2 and A3 events in the above example respectively have the same corresponding measurement resources, reporting content and reporting amount. Of course, the measurement resources, reporting content and reporting amount corresponding to different events may also be different, and this application does not impose any restrictions on this.

[0147] Case 2: The first network device configures multiple events in one measurement configuration information.

[0148] In case 2, the measurement configuration information includes first configuration information, and the first configuration information may include multiple event configurations and multiple second identifiers corresponding to the multiple event configurations respectively.

[0149] The measurement resources, reporting contents and reporting quantities corresponding to the multiple event configurations may be the same or different.

[0150] When the first configuration information includes multiple event configurations, the first network device can configure multiple first events to the UE through one measurement configuration information. At this time, the first identifier corresponding to the measurement configuration information and the multiple events are in a one-to-many relationship.

[0151] Based on this, the measurement identifier also includes a second identifier, so that the UE can send the first identifier and the second identifier together to the first network device through the L1 measurement report, so that after receiving the L1 measurement report, the first network device can obtain the relevant parameters of the first event corresponding to the second identifier in the measurement configuration information corresponding to the first identifier according to the first identifier and the second identifier in the L1 measurement report.

[0152] Taking the example that the first network device configures the A2 event and the A3 event for the UE at the same time through the first information, the code of the first information may be as follows:

[0153]

[0154]

[0155] Based on the above code, it can be known that the first information includes a measurement configuration information, and the measurement configuration information includes event configuration 1 and event configuration 2. Event configuration 1 is used to configure A2 event, and event configuration 2 is used to configure A3 event.

[0156] The measurement resources, reporting contents, and reporting amounts corresponding to the A2 event and the A3 event in the above example are the same, and event configuration 1 and event configuration 2 share the same measurement resources, reporting contents, and reporting amount configurations. Of course, the measurement resources, reporting contents, and reporting amounts corresponding to different event configurations may also be different. When the corresponding measurement resources, reporting contents, and reporting amounts of different event configurations are the same, the measurement resources, reporting contents, and reporting amount configurations may be shared, or they may be configured separately, and this application does not impose any restrictions on this.

[0157] Based on the above situation 1 and situation 2, the first network device may also configure the measurement resources, reporting content and reporting amount corresponding to the first event to the UE in the first information in a variety of ways.

[0158] In method 1, the first network device may configure the measurement resources, reporting content, and reporting amount corresponding to the first event in the measurement configuration information.

[0159] It should be noted that method 1 is applicable to the situation where the first configuration information includes only one event configuration, or, the first configuration information includes multiple event configurations, and the measurement resources, reporting contents and reporting quantities corresponding to the first events of the multiple event configurations are exactly the same.

[0160] The measurement configuration information also includes a third identifier, second configuration information and third configuration information.

[0161] The third identifier is used to identify the measurement resource for the UE to perform layer 1 measurement on the LTM candidate cell.

[0162] The second configuration information is used to indicate the reporting content of the L1 measurement report performed by the UE.

[0163] The third configuration information is used to indicate the reporting amount of L1 measurement reporting performed by the UE.

[0164] Taking the case where the first network device configures A2 and A4 events for the UE through the first information as an example, the code of the first information may be as follows:

[0165]

[0166]

[0167] Based on the above code, it can be known that the first information includes one measurement configuration information, and one measurement configuration information includes two event configurations, namely event configuration 1 and event configuration 2. Event configuration 1 is used to configure A2 event, and event configuration 2 is used to configure A4 event. The third identifier, the second configuration information and the third configuration information are configured in parallel with the first configuration information in the measurement configuration information.

[0168] In the above-mentioned method 1, all event configurations share the third identifier, the second configuration information and the third configuration information. The first network device does not need to separately add measurement resources, reporting content and reporting amount configurations to each event configuration, thereby reducing the amount of data of the first information sent by the first network device to the UE, which is conducive to saving network resources.

[0169] In method 2, the first network device may configure the reporting content and reporting amount corresponding to the first event in the first configuration information.

[0170] The first configuration information also includes one or more fourth configuration information corresponding to the one or more event configurations, and one or more fifth configuration information corresponding to the one or more event configurations.

[0171] The fourth configuration information is used to indicate the reporting content of the layer 1 measurement report performed by the UE for the first event.

[0172] The fifth configuration information is used to indicate the reporting amount of the layer 1 measurement report performed by the UE for the first event.

[0173] Taking the case where the first network device configures the A2 event for the UE through the first information as an example, the code of the first information may be as follows:

[0174]

[0175] Based on the above code, it can be known that the first information includes a measurement configuration information, and a measurement configuration information includes an event configuration, and the event configuration is used to configure the A2 event. The fourth configuration information and the fifth configuration information are configured in parallel with the event configuration in the first configuration information.

[0176] In the above-mentioned method 2, the first network device separately adds configurations of reporting content and reporting amount for each event configuration, and can configure a variety of different events that trigger L1 measurement reporting for the UE, thereby increasing the flexibility of the UE in performing L1 measurement.

[0177] Based on the above exemplary description, in mode 2, the first network device may configure measurement resources for the UE in multiple ways.

[0178] Mode 2.1: The first network device may configure the measurement resource in the first configuration information.

[0179] The first configuration information also includes one or more fourth identifiers corresponding to the one or more event configurations.

[0180] The fourth identifier is used to indicate the measurement resources for the UE to perform L1 measurement on the LTM candidate cell for the first event.

[0181] Taking the example that the first information includes a measurement configuration information, and the first network device configures the A2 event, the A3 event, and the A4 event for the UE at the same time through the first information, the code of the first information may be as follows:

[0182]

[0183]

[0184]

[0185] Based on the above code, it can be known that the first information includes a measurement configuration information, and a measurement configuration information includes multiple event configurations, namely event configuration 1, event configuration 2 and event configuration 3. Event configuration 1 is used to configure A2 event, event configuration 2 is used to configure A3 event, and event configuration 3 is used to configure A4 event. Multiple fourth identification configurations are in the first configuration information, corresponding to event configuration 1, event configuration 2 and event configuration 3, respectively.

[0186] In addition, the fourth configuration information and the fifth configuration information in the above example are configured in the first configuration information. Of course, the fourth configuration information and the fifth configuration information can also be configured in the measurement configuration information, and this application does not limit this.

[0187] In the above-mentioned method 2.1, the first network device separately adds the configuration of measurement resources for each event configuration, and can configure different events for triggering L1 measurement reporting behavior for the UE according to various measurement resources, thereby increasing the flexibility of the UE in performing L1 measurement.

[0188] Mode 2.2: The first network device may configure measurement resources in the measurement configuration information.

[0189] It should be noted that method 2.2 is applicable to the case where the measurement resources corresponding to the first events of multiple event configurations are completely the same.

[0190] The measurement configuration information also includes a third identifier.

[0191] The third identifier is used to indicate the measurement resources for the UE to perform layer 1 measurement on the LTM candidate cell.

[0192] Taking the example that the first information includes a measurement configuration information, and the first network device configures the A2 event and the A3 event for the UE at the same time through the first information, the code of the first information may be as follows:

[0193]

[0194]

[0195] Based on the above code, it can be known that the first information includes a measurement configuration information, and a measurement configuration information includes multiple event configurations, namely event configuration 1 and event configuration 2. Event configuration 1 is used to configure A2 event, and event configuration 2 is used to configure A3 event. The third identifier is configured in the measurement configuration information.

[0196] In addition, the fourth configuration information and the fifth configuration information in the above example are configured in the measurement configuration information. Of course, the fourth configuration information and the fifth configuration information may also be configured in the first configuration information, and this application does not limit this.

[0197] In the above-mentioned method 2.2, all event configurations share the same measurement resource, and the first network device does not need to add measurement resource configuration to each event configuration separately, thereby reducing the amount of data of the first information sent by the first network device to the UE, which is conducive to saving network resources.

[0198] Based on the above exemplary description, in Mode 1 or Mode 2.2, the measurement identifier further includes a second identifier.

[0199] Since in Mode 1 and Mode 2.2, all events share the configuration of the same measurement resource, the UE only needs to carry the first identifier and the second identifier in the L1 measurement report to inform the first network device which event configuration triggered the measurement reporting behavior, so that the first network device can correctly instruct the UE to perform cell switching according to the L1 measurement report.

[0200] Based on the above exemplary description, in Mode 2 or Mode 2.1, the measurement identifier further includes a second identifier and / or a fourth identifier.

[0201] The UE can inform the first network device which event configuration triggered the measurement reporting behavior by carrying the first identifier and the second identifier, or the first identifier and the fourth identifier, or the first identifier, the second identifier and the fourth identifier in the L1 measurement report, so that the first network device can correctly instruct the UE to perform cell switching according to the L1 measurement report.

[0202] Among them, the method of carrying the first identifier and the second identifier is applicable to the situation where all events are configured with the same measurement resources, and the first events in multiple event configurations are different events; the method of carrying the first identifier and the fourth identifier is applicable to the situation where the first events in multiple event configurations are different events, and the measurement resources corresponding to each event are different resources.

[0203] Based on the above exemplary description, before S101, the first network device needs to determine the LTM candidate cell and the first information.

[0204] Next, combine Figure 2 , introduces the method for determining LTM candidate cells and first information provided by this application.

[0205] Figure 2 This is a signaling interaction diagram of a measurement configuration method provided in an embodiment of the present application. Figure 2 As shown, before S101, the method further includes:

[0206] Sa1. The UE performs L3 measurement and sends an L3 measurement report to the first network device.

[0207] Correspondingly, the first network device receives the L3 measurement report sent by the UE.

[0208] When the UE initially accesses the first network device, the first network device sends the L3 measurement configuration to the UE, so that the UE can perform periodic or non-periodic L3 measurements on neighbor cells and serving cells according to the L3 measurement configuration to obtain an L3 measurement report.

[0209] The L3 measurement report includes one or more L3 measurement results, and the L3 measurement results are used to indicate one or more measurement values ​​of RSRP measurement values, RSRQ measurement values, or SINR measurement values ​​of neighbor cells and serving cells.

[0210] Therefore, the first network device obtains the L3 measurement result, so as to determine, according to the L3 measurement result, a cell that can be used for the UE to perform L1 measurement and LTM cell switching.

[0211] Sa2. The first network device determines a first candidate cell according to the L3 measurement report.

[0212] The first network device may determine, according to the L3 measurement report, a cell whose L3 measurement result is greater than a preset threshold as a first candidate cell.

[0213] Sa3. The first network device determines whether the first candidate cell includes the cell of the second network device.

[0214] If the first candidate cells include the cell of the second network device, execute Sa4; if the first candidate cells are all cells of the first network device, execute Sa7.

[0215] Sa4. The first network device sends a switching request message to the second network device.

[0216] Correspondingly, the second network device receives the switching request information sent by the first network device.

[0217] The handover request information is used to request available resources of the second candidate cell.

[0218] The second candidate cell is a cell in the first candidate cell except the third candidate cell, and the second candidate cell is a cell of the second network device.

[0219] The third candidate cell is a cell of the first network device in the first candidate cell.

[0220] The second network device may be a network device adjacent to the first network device.

[0221] Considering that the first network device cannot know which available resources of the cell of the second network device in the first candidate cell are, the first network device needs to request the available resources of the second candidate cell by sending a handover request message to the second network device.

[0222] Sa5. The third network device sends response information to the first network device.

[0223] Correspondingly, the first network device receives the response information sent by the third network device.

[0224] The response information is used to indicate available resources of the fourth candidate cell.

[0225] The fourth candidate cell is a cell in the second candidate cells that the UE is allowed to access, and the fourth candidate cell is a cell of a third network device. The third network device is a network device corresponding to the cell in the second network device that the UE is allowed to access.

[0226] After receiving the switching request information, the second network device determines whether the second candidate cell allows UE access. If the UE access is allowed, the second network device can send a response message to the first network device. The response information is used to indicate the available resources of the fourth candidate cell, so that the first network device can know the available resources of the fourth candidate cell to facilitate determining the measurement resources.

[0227] In addition, if the UE is not allowed to access, the second network device may send reason information to the first network device, where the reason information is used to explain to the first network device the reason why the access is not allowed.

[0228] Sa6. The first network device generates first information according to the response information and the third candidate cell.

[0229] The LTM candidate cells include a third candidate cell and a fourth candidate cell.

[0230] Based on this, the first network device obtains the available resources of the fourth candidate cell according to the response information, directly determines the available resources of the third candidate cell according to the third candidate cell, and generates the first information based on the available resources of the fourth candidate cell and the available resources of the third candidate cell, as well as the RRC underlying configuration of the third candidate cell and the fourth candidate cell.

[0231] Sa7. The first network device generates first information according to the first candidate cell.

[0232] Among them, the LTM candidate cell is the first candidate cell.

[0233] If all the first candidate cells are cells of the first network device, the first network device may directly determine the available resources of the first candidate cells, and generate the first information based on the available resources of the first candidate cells and the RRC underlying configuration of the first candidate cells.

[0234] In summary, the first network device determines the first information so as to configure L1 measurement for the UE.

[0235] Exemplarily, the present application also provides a communication device.
