Description

Technical Field

[0001] The embodiments of the present application relate to the field of mobile communication technologies, and specifically, to a method and apparatus for reporting indication information, a terminal device, and a network device. Background Art

[0002] The purpose of a measurement gap (MG) is to create a small gap during which a terminal device measures a target cell. There are two types of measurement gaps configured by the network side: one is the measurement gap for a user equipment (UE), called per-UE gap, and the other is the measurement gap for a frequency range (FR), called per-FR gap. Among them, the measurement gap for FR includes the measurement gap for FR1 and the measurement gap for FR2.

[0003] In R16, a reporting mechanism for measurement gap requirement (i.e., NeedForGap) indication information is introduced. Specifically, a terminal device reports a list of frequency bands (bands) and indicates whether each band in the band list requires a measurement gap. However, R16 only designs the NeedForGap indication information reporting mechanism for the new radio (NR) stand-alone (SA) scenario and does not consider the multi-radio access technology - dual connectivity (MR-DC) scenario.

[0050] It should be understood that the terms "system" and "network" are often used interchangeably in this article.

In addition, the character " / " in this article generally represents an "or" relationship between the preceding and following associated objects.

[0051] To facilitate the understanding of the technical solutions of the embodiments of the present application, the following describes the technical solutions related to the embodiments of the present application.

[0052] With the pursuit of rate, latency, high-speed mobility, energy efficiency by people and the diversity and complexity of services in future life, for this reason, the 3rd Generation Partnership Project (3GPP) international standards organization began to research and develop 5G. The main application scenarios of 5G are: enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communications (URLLC), and massive Machine-Type Communications (mMTC). rd Generation Partnership Project, 3GPP) international standards organization began to research and develop 5G. The main application scenarios of 5G are: enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communications (URLLC), and massive Machine-Type Communications (mMTC).

[0053] On the one hand, eMBB still aims at users' access to multimedia content, services and data, and its demand is growing very rapidly. On the other hand, since eMBB may be deployed in different scenarios, such as indoors, urban areas, rural areas, etc., there are significant differences in its capabilities and requirements. Therefore, it cannot be generalized and must be analyzed in detail in combination with specific deployment scenarios. Typical applications of URLLC include: industrial automation, power automation, remote medical operations (surgery), traffic safety assurance, etc. Typical features of mMTC include: high connection density, small data volume, latency-insensitive services, low cost and long service life of modules, etc.

[0054] In the early deployment of NR, it was difficult to obtain complete NR coverage. Therefore, the typical network coverage was a wide-area LTE coverage and an NR island coverage mode. Moreover, a large number of LTEs were deployed below 6 GHz, and there was little spectrum below 6 GHz available for 5G. Therefore, NR must study spectrum applications above 6 GHz, but the high-frequency band coverage is limited and the signal fades quickly. At the same time, in order to protect the mobile operators' previous investment in LTE, a tight interworking mode between LTE and NR was proposed.

[0055] In order to be able to deploy and commercially apply 5G networks as soon as possible, 3GPP first completed the first 5G version, namely EN-DC (LTE-NR Dual Connectivity). In EN-DC, the LTE base station (eNB) serves as the master node (MN), and the NR base station (gNB or en-gNB) serves as the secondary node (SN), connecting to the EPC core network. In the later stage of R15, other DC modes will be supported, namely NE-DC, 5GC-EN-DC, and NR DC. In NE-DC, the NR base station serves as the MN, and the eLTE base station serves as the SN, connecting to the 5GC core network. In 5GC-EN-DC, the eLTE base station serves as the MN, and the NR base station serves as the SN, connecting to the 5GC core network. In NR DC, the NR base station serves as the MN, and the NR base station serves as the SN, connecting to the 5GC core network.

[0056] As Figure 2 A dual-connection architecture diagram is given. Among them, the terminal device can establish a radio interface connection with the MN to achieve communication with the MN; the terminal device can also establish a radio interface connection with the SN to achieve communication with the SN.

[0057] The technical solution of the embodiment of the present application can be applied not only to a dual-connection architecture (such as an MR-DC architecture), but also to a multiple connectivity (MC) architecture. Typically, the MC architecture can be an MR-MC architecture.

[0058] RRC state

[0059] For the purpose of reducing the signaling in the air interface and quickly restoring the radio connection and quickly resuming the data service, 5G defines a new Radio Resource Control (RRC) state, namely the RRC_INACTIVE state. This state is different from the RRC_IDLE state and the RRC_CONNECTED state. Among them,

[0060] 1) RRC_IDLE state (abbreviated as idle state): The mobility is based on the cell selection and reselection of the terminal device. Paging is initiated by the Core Network (CN), and the paging area is configured by the CN. There is no terminal device context on the base station side, and there is no RRC connection.

[0061] 2) RRC_CONNECTED state (abbreviated as connected state): There is an RRC connection, and there is a terminal device context on both the base station side and the terminal device side. The network side knows the location of the terminal device at the specific cell level. The mobility is the mobility controlled by the network side. Unicast data can be transmitted between the terminal device and the base station.

[0062] 3) RRC_INACTIVE state (abbreviated as inactive state): The mobility is based on the cell selection and reselection of the terminal device. There is a connection between the CN and the NR. The terminal device context exists on a certain base station. Paging is triggered by the RAN, and the RAN-based paging area is managed by the RAN. The network side knows the location of the terminal device at the RAN-based paging area level.

[0063] For the terminal device in the connected state, if it needs to perform inter-frequency or inter-system measurements, the network side needs to configure the measurement interval. During the measurement interval period, the terminal device stops all services. In addition, inter-frequency measurements may also require a measurement interval.

[0064] NR supports the measurement interval configured per UE (i.e., per-UE gap configuration) and the measurement interval configured per FR (i.e., per-FR gap configuration).

[0065] For the per-UE gap configuration: The MN determines the gap pattern and the related gap sharing configuration;

[0066] For the per-FR gap configuration: For EN-DC, the MN determines the FR1 gap configuration and the related gap sharing configuration; the SN determines the FR2 gap configuration and the related gap sharing configuration.

[0067] The network side distributes the measurement interval configuration to the terminal device in the following manner: The MN distributes the per UE gap configuration or the FR1 gap configuration to the terminal device. The MN also notifies the SN about the per UE gap configuration or the FR1 gap configuration, as well as the measurement interval purpose (gap purpose). Here, the gap purpose is, for example, that the measurement interval is per-UE configured or per-FR configured.

[0068] For the per-UE gap, the SN notifies the MN about the FR1 frequency list and the FR2 frequency list to be configured by the SN; for the per-FR gap, the MN notifies the SN about the FR1 frequency list to be configured by the MN, and the SN notifies the MN about the FR2 frequency list to be configured by the SN.

[0069] For NE-DC and NR-DC, the MN simultaneously determines the FR1 gap configuration and the related gap sharing configuration and the FR2 gap configuration and the related gap sharing configuration.

[0070] For NE-DC, the MN notifies the SN about the per-UE gap configuration or the FR1 gap configuration. The SN provides a measurement interval requirement request to the MN, but no frequency list is required. For NR-DC, the MN notifies the SN about the per-UE gap configuration or the FR1 gap configuration, the FR2 gap configuration, and the gap purpose. The SN can indicate to the MN about the FR1 frequency list and the FR2 frequency list to be configured by the SN.

[0071] In R16, a reporting mechanism for measurement gap requirement (i.e., NeedForGap) indication information was introduced. The basic principle is that the network side configures a list of bands for which the terminal device needs to report measurement gap requirement indication information, and then the terminal device determines whether each band in the band list requires a measurement gap based on the existing radio resource configuration (i.e., for RRM measurements on the band, whether the terminal device requires a measurement gap configuration). R16 only designed the NeedForGap indication information reporting mechanism for the NR SA scenario and did not consider the MR-DC scenario. For example, it did not consider issues such as NeedForGap configuration and inter-network negotiation configuration in the MR-DC scenario, and did not consider issues such as reporting and updating of measurement gap requirement indication information. Therefore, the following technical solutions of the embodiments of this application are proposed. The technical solutions of the embodiments of this application propose a solution for how the terminal device reports NeedForGap indication information in the MR-DC scenario, a solution for how to coordinate the configuration between the MN and the SN, and a solution for NeedForGap update during the mobility process of the terminal device.

[0072] It should be noted that FR1 and FR2 in the embodiments of this application refer to NR FR1 and NR FR2. Among them, the frequency range NR FR1 generally refers to the 5G Sub-6GHz (below 6GHz) band, and may also be extended to sub-7GHz (below 7GHz) in the future. The frequency range NR FR2 generally refers to the 5G millimeter wave band.

[0073] It should be noted that the per-UE gap configuration in the embodiments of this application is used to indicate the measurement gap configuration for all frequencies (including FR1 and FR2). The per-FR gap configuration in the embodiments of this application supports two configurations, namely FR1 gap configuration and FR2 gap configuration. Among them, the FR1 gap configuration is used to indicate the measurement gap configuration for FR1, and the FR2 gap configuration is used to indicate the measurement gap configuration for FR2. In an example, the information of the measurement gap configuration is shown in Table 1 below:

[0074]

[0075] Table 1

[0076] Figure 3 is a schematic flow chart of the method for reporting indication information provided by the embodiments of this application. As Figure 3 shown, the method for reporting indication information includes the following steps:

[0077] Step 301: The terminal device reports first information, which is used to determine the measurement interval requirement indication information for each band in the first band list, and the measurement interval requirement indication information is used to indicate whether a measurement interval is required for that band; wherein, the first band list is determined based on at least one of the following: the band list configured by the MN side, the band list configured by the SN side, and the band list supported by the terminal device.

[0078] In the embodiments of the present application, the measurement interval requirement indication information may also be referred to as NeedForGap indication information. The measurement interval requirement indication information is in terms of bands and is used to indicate whether a measurement interval is required for a band or to indicate whether a measurement interval configuration is required for a band.

[0079] In the embodiments of the present application, the first information reported by the terminal device includes the measurement interval requirement indication information for each band in the first band list. Here, the first band list is determined based on at least one of the following: the band list configured by the MN side, the band list configured by the SN side, and the band list supported by the terminal device.

[0080] In an example, the first information includes the indication information (Band indicator) of at least one band and the measurement interval requirement indication information (i.e., NeedForGap indication information) associated with each band in the at least one band. Among them, the at least one band constitutes the first band list.

[0081] It should be noted that the band list configured by the MN side in the embodiments of the present application may also be replaced by the band list supported by the MN side. The band list configured by the SN side in the embodiments of the present application may also be replaced by the band list supported by the SN side.

[0082] In an optional manner, the first band list includes the band list configured by the MN side and / or the band list configured by the SN side. In another optional manner, the first band list is the band list supported by the terminal device. In yet another optional manner, the first band list is the band list of the bands supported by the terminal device that fall within a specific spectrum range, and the specific spectrum range is the spectrum range corresponding to the measurement interval configured by the SN and / or the MN. The following describes how the terminal device reports the measurement interval requirement indication information in different cases.

[0083] ● Reporting of the measurement interval requirement indication information in the MR-DC scenario (for the case where there is no negotiation between the MN and the SN).

[0084] Solution 1: When the measurement interval configuration on the MN side is per-UE gap configuration, the first information is used to determine the measurement interval requirement indication information for each band in the band list configured on the MN side; or, the first information is used to determine the measurement interval requirement indication information for each band in the band list supported by the terminal device.

[0085] In an optional manner, after receiving the RRC connection reconfiguration message or RRC connection resume message sent by the MN, the terminal device sends the first information to the MN.

[0086] For example: If the measurement interval configuration on the MN side is per-UE gap configuration, then after receiving the RRC connection reconfiguration message or RRC connection resume message sent by the MN, the terminal device sends the first information to the MN. The first information is used to determine the measurement interval requirement indication information for each band in the first band list, and the measurement interval requirement indication information is used to indicate whether the band requires a measurement interval. Here, the first information is used to determine the measurement interval requirement indication information for each band in the band list supported by the terminal device or the measurement interval requirement indication information for each band in the band list configured on the MN side.

[0087] Solution 2: When the measurement interval configuration on the MN side is per-FR gap configuration, the first information is used to determine the measurement interval requirement indication information for each band in the band list configured on the MN side and / or the band list configured on the SN side; or, the first information is used to determine the measurement interval requirement indication information for each band in the band list supported by the terminal device; or, the first information is used to determine the measurement interval requirement indication information for each band in the band list of the bands supported by the terminal device that fall within a specific spectrum range, where the specific spectrum range is the spectrum range corresponding to the measurement interval configured by the SN and / or the MN.

[0088] In an optional manner, after receiving the RRC connection reconfiguration message or RRC connection resume message sent by the MN, the terminal device sends the first information to the MN.

[0089] For example: If the measurement gap configuration on the MN side is per-FR gap configuration, after the terminal device receives the RRC connection reconfiguration message or the RRC connection resume message, it sends the first information to the MN. The first information is used to determine the measurement gap requirement indication information for each band in the first band list. The measurement gap requirement indication information is used to indicate whether a measurement gap is required for that band. Here, in an optional manner, the first band list includes the band list configured on the MN side and the band list configured on the SN side. In another optional manner, the first band list includes the measurement gap requirement indication information for each band in the band list within the spectral range corresponding to the measurement gap configured by the MN in the band list supported by the terminal device, and the measurement gap requirement indication information for each band in the band list within the spectral range corresponding to the measurement gap configured by the SN in the band list supported by the terminal device. That is to say, the first information is used to determine the measurement gap requirement indication information for each band in the two band lists, where one band list is associated with the MN and the other band list is associated with the SN.

[0090] In an optional manner, after the first information is received by the MN, all or part of the information in the first information is forwarded by the MN to the SN. Among them, the partial information of the first information includes the measurement gap requirement indication information for each band in the band list configured on the SN side; or, the partial information of the first information includes the measurement gap requirement indication information for each band in the band list within a specific spectral range in the band list supported by the terminal device, and the specific spectral range is the spectral range corresponding to the measurement gap configured by the SN.

[0091] Solution 3: The terminal device receives the first configuration information and / or the second configuration information. The first configuration information is used to determine the band list configured on the MN side, and the second configuration information is used to determine the band list configured on the SN side. The terminal device reports the first information based on the first configuration information and / or the second configuration information.

[0092] I) In an optional manner, when the measurement gap configuration on the MN side is per-UE gap configuration, the first configuration information is sent by the MN to the terminal device.

[0093] II) In another optional manner, when the measurement gap configuration on the MN side is per-FR gap configuration, the first configuration information is sent by the MN to the terminal device, and the second configuration information is sent by the SN to the terminal device.

[0094] It should be noted that the band list configured on the MN side or the band list configured on the SN side can also be referred to as a filtered band list, which is used to indicate the set of bands for which the terminal device reports the measurement interval requirement indication information per band.

[0095] For example: The terminal device receives the band list configured on the MN side. This band list is used to indicate the set of bands for which the terminal device reports the measurement interval requirement indication information per band. The terminal device sends the measurement interval requirement indication information for each band in this band list to the MN according to the band list configured on the MN side. The measurement interval requirement indication information is used to indicate whether a measurement interval is required for this band. The terminal device receives the band list configured on the SN side. This band list is used to indicate the set of bands for which the terminal device reports the measurement interval requirement indication information per band. The terminal device sends the measurement interval requirement indication information for each band in this band list to the SN according to the band list configured on the SN side. The measurement interval requirement indication information is used to indicate whether a measurement interval is required for this band. It should be noted that if it is a per-UE gap configuration, only the MN configures the band list for the terminal device. If it is a per-FR gap configuration, the MN and the SN respectively configure the band list for the terminal device.

[0096] ●Reporting of measurement interval requirement indication information in the MR-DC scenario (for the case where there is negotiation between the MN and the SN).

[0097] The terminal device receives the first configuration information and / or the second configuration information. The first configuration information is used to determine the band list configured on the MN side, and the second configuration information is used to determine the band list configured on the SN side. The terminal device reports the first information based on the first configuration information and / or the second configuration information.

[0098] Solution A: When the measurement interval configuration on the MN side is a per-FR gap configuration and the MN determines that the terminal device only reports the measurement interval requirement indication information to the MN, the first configuration information and / or the second configuration information is sent by the MN to the terminal device; the terminal device sends the measurement interval requirement indication information for each band in the band list configured on the MN side and / or the band list configured on the SN side to the MN.

[0099] In an alternative manner, when the MN determines that the terminal device only reports the measurement interval requirement indication information to the MN, the third indication information is sent by the MN to the terminal device and / or the SN; wherein, the third indication information is used to indicate that the terminal device only reports the measurement interval requirement indication information to the MN; and / or, the third indication information is used to indicate that the SN forwards the second configuration information to the MN.

[0100] In an alternative manner, after the first information is received by the MN, the measurement interval requirement indication information of each band in the band list configured on the SN side is forwarded by the MN to the SN.

[0101] Solution B: When the measurement interval configuration on the MN side is a per-FR gap configuration, and the MN determines that the terminal device reports the measurement interval requirement indication information to the MN and / or the SN respectively, the first configuration information and / or the second configuration information is sent by the MN to the terminal device, or, the first configuration information is sent by the MN to the terminal device and / or the second configuration information is sent by the SN to the terminal device; the terminal device sends the measurement interval requirement indication information of each band in the band list configured on the MN side to the MN, and / or sends the measurement interval requirement indication information of each band in the band list configured on the SN side to the SN.

[0102] I) In an alternative manner, when the MN determines that the terminal device reports the measurement interval requirement indication information to the MN and / or the SN respectively, the fourth indication information is sent by the MN to the terminal device and / or the SN; wherein, the fourth indication information is used to indicate that the terminal device reports the measurement interval requirement indication information to the MN and / or the SN respectively; and / or, the fourth indication information is used to indicate that the SN configures the second configuration information for the terminal device;

[0103] Correspondingly, the first configuration information is sent by the MN to the terminal device and / or the second configuration information is sent by the SN to the terminal device.

[0104] II) In another alternative manner, when the MN determines that the terminal device reports the measurement interval requirement indication information to the MN and / or the SN respectively, the fourth indication information is sent by the MN to the terminal device and / or the SN; wherein, the fourth indication information is used to indicate that the terminal device reports the measurement interval requirement indication information to the MN and / or the SN respectively; and / or, the fourth indication information is used to indicate that the SN forwards the second configuration information to the MN;

[0105] Accordingly, the first configuration information and / or the second configuration information is / are sent by the MN to the terminal device.

[0106] The following is described with specific examples.

[0107] (1) The MN determines whether the terminal device reports the measurement interval requirement indication information to the MN or to the MN and the SN.

[0108] (2) If the MN determines that the terminal device only reports the measurement interval requirement indication information to the MN, the MN sends an indication information to the terminal device, which is used to indicate that only the measurement interval requirement indication information is reported to the MN. In addition, the MN sends an indication information to the SN, which is used to indicate that only the measurement interval requirement indication information is reported to the MN and / or the band list configured on the SN side is sent to the MN; the SN sends the band list configured on the SN side to the MN, and the MN combines the band list configured on the MN side and the band list configured on the SN side to form a new band list and sends it to the terminal device, which is used to indicate the band set for the terminal device to report the measurement interval requirement indication information. After the MN receives the measurement interval requirement indication information of each band in the reported band set from the terminal device, it forwards all or part of the information in the reported information to the SN. For example, the MN forwards the measurement interval requirement indication information of each band in the band list configured on the SN side to the SN.

[0109] In an alternative manner, the value of the above indication information can be one of {MN, SN, both}, where the value of the above indication information being MN represents that only the measurement interval requirement indication information is reported to the MN, the value of the above indication information being SN represents that only the measurement interval requirement indication information is reported to the SN, and the value of the above indication information being both represents that the measurement interval requirement indication information is reported to the MN and the SN respectively.

[0110] In another alternative manner, the above indication information can be gap purpose. Gap purpose indicating that the measurement interval is per-UE configured represents that only the measurement interval requirement indication information is reported to the MN, and gap purpose indicating that the measurement interval is per-FR gap configured represents that the measurement interval requirement indication information is reported to the MN and the SN respectively.

[0111] (3) If it is the MN that determines that the terminal device reports the measurement interval requirement indication information to the MN and the SN respectively, the MN sends an indication information to the terminal device, which is used to indicate that the terminal device reports the measurement interval requirement indication information to the MN and the SN respectively.

[0112] In addition, the MN sends an indication information to the SN, which is used to indicate that the terminal device reports the measurement interval requirement indication information to the MN and the SN respectively.

[0113] Further, in an optional manner, the indication information is further used to instruct the SN to send the band list configured on the SN side to the terminal device. That is to say, the MN and the SN respectively configure a band list for the terminal device, and the terminal device reports the measurement interval requirement indication information of each band in the band list to the MN based on the band list configured on the MN side; and, the terminal device reports the measurement interval requirement indication information of each band in the band list to the SN based on the band list configured on the SN side.

[0114] Further, in an optional manner, the indication information is further used to instruct the SN to send the band list configured on the SN side to the MN. That is to say, the MN combines the band list configured on the MN side and the band list configured on the SN side to form a new band list and sends it to the terminal device, which is used to indicate the band set for the terminal device to report the measurement interval requirement indication information. The terminal device reports the measurement interval requirement indication information of each band in the band list to the MN based on the band list configured on the MN side, and reports the measurement interval requirement indication information of each band in the band list to the SN based on the band list configured on the SN side.

[0115] ● Impact of Mobility on the Reporting of Measurement Interval Requirement Indication Information

[0116] Scenario 1: MR-DC Scenario

[0117] The terminal device reports the updated first information or the updated information of the first information under the trigger of at least one of the following events:

[0118] MN handover, SN change, change of the serving cell on the MN side, change of the serving cell on the SN side, the network side reconfigures the band list on the MN side, the network side reconfigures the band list on the SN side.

[0119] Here, the change of the serving cell is, for example, the addition and / or deletion of SCell.

[0120] In an optional manner, under the trigger of at least one of the following events, the network side is triggered to reconfigure the band list for the terminal device (for example, configure the band list on the MN side, reconfigure the band list on the SN side): MN handover, SN change, change of the serving cell on the MN side, change of the serving cell on the SN side. When the network side reconfigures the band list for the terminal device, it will trigger the terminal device to report the updated first information or the updated information of the first information.

[0121] In the above solution, optionally, the update information of the first information includes: a fifth indication information and a sixth indication information, where the fifth indication information and the sixth indication information are used to determine the updated first information; where

[0122] The fifth indication information is used to determine the measurement interval requirement indication information of the valid bands in the first information reported most recently;

[0123] The sixth indication information is used to determine the measurement interval requirement indication information of each band in the second band list.

[0124] In one example, the fifth indication information includes a first bitmap, where each bit in the first bitmap has a corresponding relationship with each band in the third band list, and the third band list is the band list corresponding to the first information reported by the terminal device most recently. The value of the bit is used to indicate whether the measurement interval requirement indication information of the band corresponding to the bit is valid.

[0125] In the above solution, the bits in the first bitmap correspond one by one in sequence with the bands in the third band list from the low bit to the high bit. The value of each bit in the first bitmap is used to indicate whether the measurement interval requirement indication information of the band corresponding to the bit is valid. It should be noted that the measurement interval requirement indication information of the band corresponding to the bit refers to the measurement interval requirement indication information of the band in the first information reported most recently. For example: when the value of the bit is 0, it is used to indicate that the measurement interval requirement indication information of the band corresponding to the bit is invalid and the measurement interval requirement indication information of this band reported most recently needs to be released; when the value of the bit is 1, it is used to indicate that the measurement interval requirement indication information of the band corresponding to the bit is valid and the measurement interval requirement indication information of this band reported most recently needs to be retained. In addition, the terminal device also reports the measurement interval requirement indication information of the bands in the new band list (i.e., the second band list). The network side will save the merged measurement interval requirement indication information of the valid bands indicated by the first bitmap and the newly reported measurement interval requirement indication information of the bands together.

[0126] It should be noted that the manner in which the terminal device reports the updated first information or the update information of the first information may refer to the relevant description of the terminal device reporting the first information mentioned above.

[0127] The following presents a special MR-DC scenario. When the SRB3 (signaling for interaction between the SN and the terminal device) is configured on the SN side, and the MN determines that the terminal device only reports the measurement interval requirement indication information to the MN, if the SN updates the serving cell configuration on the SN side (such as Scell addition, deletion, etc.) through the SRB3, then the SN notifies the MN of the update of the serving cell configuration on the SN side and / or the updated cell list. Optionally, the SN also notifies the MN of the updated band list to trigger the MN to request the first information from the terminal device again.

[0128] Scenario 2: Non-MR-DC scenario

[0129] Solution a): The source node receives the first information sent by the terminal device. The first information is used to determine the measurement interval requirement indication information for each band in the first band list, and the measurement interval requirement indication information is used to indicate whether the band requires a measurement interval. Among them, the first band list is determined based on at least one of the following: the band list configured on the source node side, the band list supported by the terminal device. When the terminal device switches from the source node to the target node, the source node sends the first information to the target node.

[0130] Here, the first information is used for the target node to determine whether to request the terminal device to report the updated first information.

[0131] In an optional manner, the first band list is the band list configured on the source node side. In another optional manner, the first band list is the band list supported by the terminal device. In yet another optional manner, the first band list is the band list of the bands supported by the terminal device that fall within a specific spectrum range, and the specific spectrum range is the spectrum range corresponding to the measurement interval configured by the source node.

[0132] In an optional manner, the source node sends the first configuration information to the target node, where the first configuration information is used to determine the band list configured on the source node side.

[0133] For example: When the source gNB triggers a handover, the source gNB forwards the band list configured on the source gNB side and the measurement interval requirement indication information for each band in the band list reported by the terminal device as part of the terminal device context to the target gNB to be handed over. The target gNB can determine whether to request the terminal device to report the updated measurement interval requirement indication information based on the existing configuration information.

[0134] Scenario b): When the radio resources of the terminal device are reconfigured, report the updated first information or the update information of the first information; wherein, the first information is used to determine the measurement interval requirement indication information for each band in the first band list, and the measurement interval requirement indication information is used to indicate whether the band requires a measurement interval; wherein, the first band list is determined based on at least one of the following: the band list configured on the serving node side of the terminal device, the band list supported by the terminal device.

[0135] Here, the reconfiguration of radio resources is, for example, that the serving node of the terminal device adds or deletes some Scells.

[0136] In an optional manner, the first band list is the band list configured on the serving node side. In another optional manner, the first band list is the band list supported by the terminal device. In yet another optional manner, the first band list is the band list within a specific spectrum range in the band list supported by the terminal device, and the specific spectrum range is the spectrum range corresponding to the measurement interval configured by the serving node.

[0137] In the above scenario, optionally, the update information of the first information includes: a fifth indication information and a sixth indication information, and the fifth indication information and the sixth indication information are used to determine the updated first information; wherein,

[0138] The fifth indication information is used to determine the measurement interval requirement indication information of the valid bands in the first information reported most recently.

[0139] The sixth indication information is used to determine the measurement interval requirement indication information for each band in the second band list.

[0140] In an example, the fifth indication information includes a first bitmap, and each bit in the first bitmap has a corresponding relationship with each band in the third band list. The third band list is the band list corresponding to the first information reported by the terminal device most recently, and the value of the bit is used to indicate whether the measurement interval requirement indication information of the band corresponding to the bit is valid.

[0141] In the above solution, the bit positions in the first bitmap correspond one by one to the bands in the third band column in the order from the lower bit to the higher bit. The value of each bit position in the first bitmap is used to indicate whether the measurement interval requirement indication information of the band corresponding to this bit position is valid. It should be noted that the measurement interval requirement indication information of the band corresponding to this bit position refers to the measurement interval requirement indication information of the band in the first information reported most recently. For example: when the value of the bit position is 0, it is used to indicate that the measurement interval requirement indication information of the band corresponding to this bit position is invalid, and the measurement interval requirement indication information of this band reported most recently needs to be released; when the value of the bit position is 1, it is used to indicate that the measurement interval requirement indication information of the band corresponding to this bit position is valid, and the measurement interval requirement indication information of this band reported most recently needs to be retained. In addition, the terminal device also reports the measurement interval requirement indication information of the bands in the new band list (i.e., the second band list). The network side will save the valid measurement interval requirement indication information indicated by the first bitmap and the newly reported measurement interval requirement indication information of the bands together.

[0142] It should be noted that the manner in which the terminal device reports the updated first information or the update information of the first information can refer to the relevant description of the terminal device reporting the first information above.
