[0001] This application relates to the field of communication technology, and in particular to an information sending and receiving method, apparatus, user equipment, and storage medium. Background Technology

[0002] Although 5G has begun commercial use, its coverage in remote ocean and land areas is limited by geographical conditions and business models. To overcome these terrain limitations, integrating satellite communication with terrestrial networks to create a seamless global network encompassing land, sea, air, and space has become a research hotspot in academia and industry. International organizations such as 3GPP and ITU have established working groups to conduct standardization research on satellite-terrestrial integration. 3GPP's NTN (Non-terrestrial networks) project focuses on integrating satellite communication with 5G, addressing key issues in NR (New Radio) support for NTN. Its standardization work will lay the technological foundation for 6G satellite-terrestrial integration research. Future integrated space-air-space networks will primarily focus on deep integration, combining diverse communication platforms to provide broader and more diversified communication services.

[0003] However, in existing technological research, access network equipment in non-terrestrial networks, such as NGSO (Non-Geostationary Orbit) satellites and LEO (Low Earth Orbit) satellites, have very large coverage areas, which can reach hundreds of square kilometers. However, different areas within the coverage area may require different services to be transmitted.

[0004] Therefore, existing technologies urgently need methods that can reflect the different services offered by different areas within the coverage area. Summary of the Invention

[0033] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the application and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present application are shown in the drawings, not the entire structure.

[0034] Before discussing the exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe the steps as sequential processes, many of these steps can be performed in parallel, concurrently, or simultaneously. Furthermore, the order of the steps can be rearranged. A process can be terminated when its operation is complete, but it may also have additional steps not included in the figures. A process can correspond to a method, function, procedure, subroutine, subroutine, etc.

[0035] It should be noted that the concepts of "first" and "second" mentioned in the embodiments of this application are only used to distinguish different devices, modules, units or other objects, and are not used to limit the order or interdependence of the functions performed by these devices, modules, units or other objects.

[0036] Furthermore, the embodiments and features described in this application may be combined with each other, unless otherwise specified.

[0037] In wireless communication networks, UEs can receive MBS configuration information and receive MBS services based on this information. MBS services include broadcast, multicast, and general-purpose services. Taking multicast as an example, multicast services can be transmitted using a point-to-multipoint (PTM) method, which allows for data transmission at a relatively low data rate. Network nodes can transmit MBS services to multiple UEs, which is more beneficial for conserving network resources when dealing with a large number of receiving UEs. MBS configuration information mainly includes configuration parameters related to UE receiving MBS services. It can be sent to the UE through dedicated Radio Resource Control (RRC) signaling, such as an RRC Release Message with suspendconfig, or through the multicast MBS control channel. This multicast MBS control channel is different from the broadcast MBS control channel (MCCH), which allows UEs in RRC connected state (RRC_CONNECTED) to receive MBS configuration information for multicast services and enter RRC inactive state (RRC_INACTIVE).

[0038] For multicast services received by the UE, existing technologies only indicate the MBS service configuration information to the UE through MBS configuration information, but do not indicate the area to which the MBS service applies. Since the UE does not know the area to which the MBS configuration information applies, it may attempt to receive the MBS service in an unsuitable area based on the MBS configuration information, but will not receive the MBS service. This leads to unnecessary power consumption, wasted resources, and packet loss in areas that originally supported the MBS configuration information, affecting the reliability of the MBS service.

[0039] As an example application scenario: A communication system has three areas: Area1, Area2, and Area3. MBS configuration information applies to Area1 and Area2, but not to Area3. However, since the UE is unaware of the applicable area for the MBS configuration information, it might attempt to receive MBS services in Area3 using the MBS configuration information, but fail to receive them, resulting in MBS service packet loss. The UE's operations in Area3 lead to unnecessary resource waste.

[0040] This application provides an indication information and its transmission and reception method. For MBS services, the network device indicates to the UE the area where the MBS service is applicable. Based on this, the UE can correctly receive MBS services in the appropriate area based on MBS configuration information, avoiding unnecessary resource waste and improving the reliability of MBS services.

[0041] In the embodiments of this application, UE (User equipment) can be referred to as a terminal, which can be a mobile terminal, a vehicle-mounted terminal, etc. The UE includes any device that provides voice and / or data connectivity to the user, such as wireless terminal devices, mobile terminal devices, device-to-device (D2D) terminal devices, vehicle-to-everything (V2X) terminal devices, machine-to-machine / machine-type communications (M2M / MTC) terminal devices, Internet of Things (IoT) terminal devices, light UE, reduced-capability UE (REDCAP UE), subscriber unit, subscriber station, mobile station, remote station, access point (AP), remote terminal, access terminal, user terminal, user agent, or user device, etc. It can also be user equipment in future communication systems, but this patent is not limited to this.

[0042] The network devices in this application embodiment can be access network devices, core network devices, or servers, etc. Access network devices can be base stations in terrestrial communication networks or base stations in NTN networks. For example, evolved NodeBs (eNBs), next-generation nodes (gNBs) in NR systems, roadside units (RSUs), centralized units (CUs) and distributed units (DUs) in cloud access network systems, and access network devices in future communication systems. Core network devices can be Mobility Management Entities (MMEs), Serving Gateways (SGWs), Packet Data Node Gateways (PGWs), Home Subscriber Servers (HSSs) storing user subscription information, Policy and Charging Rule Functions (PCRFs), etc., and can also be core network devices in future communication systems; this application is not limited to these.

[0043] This application provides a method for sending indication information, which is applicable to situations involving the transmission of indication information. Specifically, this method can be executed by an information sending device, which can be implemented through software and / or hardware and integrated into a network device.

[0044] The sending method provided in this application embodiment can be described by the following steps, as shown in Figure 1:

[0045] S1. Generate instruction information, which is used to indicate the area to which the MBS service applies, and / or to indicate one or more contents included in the MBS service;

[0046] S2. Send the instruction information to the terminal.

[0047] In this embodiment, indication information is introduced to indicate the applicable area and / or content of the MBS service. This enables the UE to receive the MBS service and / or its content in the applicable area within an NTN communication scenario. This not only avoids packet loss due to ignorance of the applicable area and / or content of the MBS service, but also prevents unnecessary resource waste by the UE in unsuitable areas.

[0048] As an example, the instruction information can indicate the region to which the MBS service applies by including the region identifier. The instruction information can also indicate the content within the MBS service by including the content identifier of the MBS service.

[0049] As an example, a UE can receive MBS configuration information and receive MBS services based on that information. Therefore, the transmission method can be described in the following steps:

[0050] S00, Generate MBS configuration information;

[0051] S10. Generate instruction information, which is used to indicate the area to which the MBS configuration information applies, and / or to indicate one or more contents contained in the MBS configuration information;

[0052] S20. Send MBS configuration information and instruction information to the terminal.

[0053] Specifically, after receiving the MBS configuration information, the UE can receive the corresponding MBS service in the area where the MBS service is applicable, based on the indication information. It should be noted that the area applicable to the MBS service can be one or more areas.

[0054] Specifically, after receiving the MBS configuration information, the UE can receive the content of the MBS service based on the indication information. It should be noted that the MBS service can contain one or more content items.

[0055] As an example, the MBS configuration information may contain MBS service configuration information for one or more MBS services. For instance, the MBS configuration information may include one or more configuration parameters corresponding to one or more MBS services. Therefore, the sending method can specifically include the following steps:

[0056] S100. Generate MBS configuration information. The MBS configuration information is used to instruct the user equipment to receive the corresponding MBS service with the MBS service configuration information of one or more MBS services in the MBS configuration information.

[0057] S200. Generate indication information, which is used to indicate the area to which the MBS service configuration information of the MBS service applies, and / or to indicate the content of the MBS service to which the MBS service configuration information of one or more MBS services applies.

[0058] S300: Send MBS configuration information and instruction information to the terminal.

[0059] Specifically, when the indication information is used to indicate the area to which the MBS service configuration information of the MBS service applies, the UE receives the MBS service configuration information of a certain MBS service in the MBS configuration information and can receive the MBS service in the area to which the MBS service applies based on the indication information.

[0060] Specifically, when the indication information indicates that the MBS service configuration information of the MBS service is used to configure a certain content of the MBS service, after the UE receives the MBS service configuration information of a certain MBS service in the MBS configuration information, it can configure according to the indication information and receive a certain content of the corresponding MBS service. When the indication information indicates that the MBS service configuration information of the MBS service is used to configure a certain MBS service, the UE can receive the corresponding MBS service according to the indication information.

[0061] In this application embodiment, the content of MBS service can be understood as follows: some MBS services are a whole, and some MBS services can be divided into one or more contents. After receiving MBS configuration information, the UE can receive one MBS service or receive one or more contents of MBS service based on the indication information.

[0062] As an example, the indication information may include the area identifier applicable to the MBS service. For instance, if the sending device transmitting the MBS configuration information covers three areas: Area1, Area2, and Area3, and the MBS service applies to Area1 and Area2, then the indication information may include area identifiers representing Area1 and Area2. Specifically, the indication information may include area IDs representing Area1 and Area2, such as Area ID1 and Area ID2; it may also include area indices representing Area1 and Area2, such as Area Index 1 and Area Index 2; and it may further include a bitmap, where the assignment of each bit in the bitmap indicates whether the MBS service applies to a corresponding area within the coverage of the sending device transmitting the MBS configuration information. For example, a bitmap of 01 indicates that the MBS service applies to Area1 within the coverage of the sending device, and a bitmap of 10 indicates that the MBS service applies to Area2 within the coverage of the sending device.

[0063] As an example, the indication information may include content identifiers for the MBS service. For instance, if the MBS service includes three contents: Content1, Content2, and Content3, the indication information may include content identifiers representing Content1, Content2, and Content3. Specifically, the indication information may include content IDs representing Content1, Content2, and Content3, such as Content ID1, Content ID2, and Content ID3; the indication information may include content indices representing Content1, Content2, and Content3, such as Content Index1, Content Index2, and Content Index3; the indication information may also include a bitmap, where the assignment of each bit in the bitmap indicates whether the MBS service is applicable to a corresponding content within the range covered by the MBS configuration information transmitting device. For example, bitmap 001 represents the first MBS service content Content1, bitmap 010 represents the second MBS service content Content1, and bitmap 100 represents the third MBS service content Content1.

[0064] In one embodiment, the transmitting device for sending indication information can be a base station in an NTN network, including transparent base stations, regenerate base stations, and other types of base stations. The base station can be mounted on non-terrestrial or airborne equipment, for example, it can be located on a satellite, space station, or other spacecraft.

[0065] If the existing technology does not indicate the area to which the MBS service applies, the UE may receive the MBS service in an unsuitable area because it does not know the area to which the MBS service applies. This could lead to MBS service packet loss in the area to which the MBS service applies, and the UE would incur unnecessary resource waste in the unsuitable area.

[0066] In this embodiment of the information transmission method, the network device can indicate the area used by the MBS service to the UE. As a result, the UE can correctly receive the MBS service in the area indicated by the indication information based on the MBS service configuration information in the MBS configuration information. This can avoid packet loss of the MBS service and reduce power consumption and save resources.

[0067] In this embodiment, the information transmission method allows the network device to indicate to the UE one or more contents included in the MBS service. The UE can then clearly identify which MBS service and which content's configuration information the MBS service configuration information refers to. Different contents within the same MBS service can be independently scheduled and configured with resources. Compared to previous methods that required identical scheduling for different contents of the same MBS service (e.g., scheduling within the same period and resource block, which occupies a larger resource block), the method adopted in this embodiment makes resource scheduling or configuration for different contents of the same MBS service more flexible. From a network resource perspective, the configuration is more flexible and effective, improving the overall utilization of network resources.

[0068] It should be noted that the MBS service in this embodiment is a service that can be transmitted via point-to-multipoint (PTM) mode, and the MBS configuration information can also be understood as point-to-multipoint configuration information (PTM Configuration). In some embodiments, the MBS configuration information in the method for sending and receiving indication information can be replaced with point-to-multipoint configuration information. For example, the indication information sending method includes: generating indication information, which is used to indicate the area to which the point-to-multipoint configuration information applies, and the point-to-multipoint configuration information is used by the user equipment to receive the MBS service; and sending the indication information to the terminal.

[0069] In one embodiment, the indication information includes at least one of first information and second information; the first information is used to indicate the area to which the MBS service applies; and the second information is used to indicate the content within the MBS service.

[0070] In one embodiment, the indication information may include only first information, which is used to indicate the area to which the MBS service applies.

[0071] In one embodiment, the indication information may include only the second information, which is used to indicate the content in the MBS service.

[0072] In one embodiment, the indication information may include both first information and second information. The first information is used to indicate the area to which the MBS service applies, and the second information is used to indicate the content within the MBS service.

[0073] In this embodiment, the first information can be used to indicate the region to which the MBS service configuration information corresponding to the MBS service applies, for a specific MBS service.

[0074] In this embodiment, the second information can be used to indicate the content of the MBS service configuration information corresponding to a specific MBS service.

[0075] For example, regarding the MBS configuration information received by the UE, the coverage area of ​​the transmitting device sending the MBS configuration information includes three areas: Area 1, Area 2, and Area 3. The MBS configuration information includes three different MBS services: MBS1, MBS2, and MBS3. For MBS1, the corresponding MBS service configuration information applies to Area 1; for MBS2, the corresponding MBS service configuration information applies to Area 1 and Area 2; and for MBS3, the corresponding MBS service configuration information does not apply to any area. In this case, the indication information may include first information, which can be used to indicate that the MBS service configuration information of MBS1 applies to Area 1, to indicate that the MBS service configuration information of MBS2 applies to Area 1 and Area 2, and to indicate that the MBS service configuration information of MBS3 does not apply to any area, i.e., it does not apply to Area 1, Area 2, and Area 3.

[0076] For example, regarding the MBS configuration information received by the UE, the MBS configuration information includes two different MBS services: MBS4 and MBS5. MBS4 is divided into two contents, Content1 and Content2, while MBS5 is a single service. In this case, the indication information may include second information. The second information can be used to indicate that one MBS service configuration information is the configuration information of the first content, Content1, of MBS4, and Content1 can be received according to this MBS service configuration information; another MBS service configuration information is the configuration information of the second content, Content2, of MBS4, and Content2 can be received according to this MBS service configuration information; and the other MBS service configuration information is the MBS service configuration information of MBS5, and the complete MBS5 can be received according to this MBS service configuration information.

[0077] In some embodiments, when the MBS service is not applicable to any region, such as the MBS3 mentioned above, the first information may indicate that the corresponding MBS service configuration information is not applicable to any region; or, the content part of the first information indicating the MBS service may be empty or may be a set default value, thereby indicating that the corresponding MBS service configuration information is not applicable to any region for MBS3.

[0078] In some embodiments, when the MBS service is a single service and is not divided into several parts, such as MBS5 being a single service, the second information can indicate that MBS5 is a single service in the corresponding MBS service configuration information for that MBS service; or, the part of the second information indicating the MBS service can be empty or can be a set default value, thereby indicating that for MBS5 as a single service, the corresponding MBS service configuration information is the complete MBS service configuration information for MBS5, and the complete MBS5 can be received according to the MBS service configuration information.

[0079] It should be noted that the indication information may include at least one of the first information and the second information. When the indication information includes the first information, the second information can be used to indicate the applicable area of ​​the MBS service configuration information for each MBS service, for one, multiple, or all MBS services. That is, the first information may indicate the applicable area of ​​the corresponding MBS service configuration information for each MBS service of the UE, or it may indicate the applicable area of ​​the corresponding MBS service configuration information only for some MBS services of the UE. Continuing the example above, the first information may indicate that the corresponding MBS service configuration information applies to Area 1 only for MBS1, and not for MBS2; or, the first information may indicate that the corresponding MBS service configuration information applies to Area 1 and Area 2 only for MBS2, and not for MBS1; or, the first information may indicate the area used by the corresponding MBS service configuration information for MBS1 and MBS2 respectively; while for MBS3, the first information may indicate that the corresponding MBS service configuration information does not apply to any area, or may not indicate the applicable area of ​​the corresponding MBS service configuration information.

[0080] It should be noted that the area to which the MBS service indicated by the first information applies (hereinafter referred to as the area indicated by the first information) can be one or more, and the content included in the MBS service indicated by the second information (hereinafter referred to as the content indicated by the second information) can also be one or more. For a given MBS service, if the indication information includes both the first and second information, the first information indicates the area to which the MBS service applies, and the second information indicates the content included in the MBS service. That is, within the area indicated by the first information, configuration can be performed according to the MBS service configuration information, and the content of the MBS service indicated by the second information can be received.

[0081] Based on the above, the UE can receive the MBS service or its content in the area where the MBS service applies, according to the indication information and based on the MBS service configuration information of the MBS service.

[0082] In this embodiment, the indication information may include first information and / or second information; correspondingly, the indication information may include the area identifier of the MBS service applicable area indicated by the first information and / or the service identifier of the applicable MBS service corresponding to the indicated area, and / or the content identifier of the content indicated by the second information for the MBS service.

[0083] In this embodiment, the first information includes the region identifier and / or the service identifier of the MBS service.

[0084] Specifically, the first information is essentially used to indicate the correspondence between MBS services and regions. That is, in multiple services and multiple regions, the correspondence indicated by the first information allows the UE to clearly specify in which region which one or more MBS services can be received. Thus, the first information can indicate the region to which an MBS service applies based on the MBS service, or it can indicate the MBS service applicable to that region based on the region.

[0085] For example, the current communication system includes three areas: Area 1 and Area 2, and two different MBS services, MBS1 and MBS2. MBS1 is applicable to Area 1 and Area 2, while MBS2 is applicable to Area 1.

[0086] The first piece of information can be a region identifier. For example, for MBS1, the region identifiers Area1 and Area2 are used to indicate that the area to which MBS1 applies is Area1 and Area2. For MBS2, the region identifier Area1 is used to indicate that the area to which MBS2 applies is Area1.

[0087] The first piece of information can be a service identifier. For example, for Area1, the service identifiers MBS1 and MBS2 are used to indicate that both MBS1 and MBS2 are applicable to Area1. For Area2, the service identifier MBS1 is used to indicate that MBS1 is applicable to Area2.

[0088] In one embodiment, when the first information is included in the MBS configuration information, the first information may be a region identifier for the region to which the MBS service applies. When the first information is included in a system message, the first information may be a service identifier for the MBS service applicable to the region.

[0089] Based on the above examples, when the first information is included in the MBS configuration information, the MBS service configuration information of MBS1 can include the area identifiers of Area1 and Area2, and the MBS service configuration information of MBS2 includes the area identifier of Area1, indicating that the area applicable to MBS1 is Area1; when the first information is included in the system message, the system message includes the service identifiers of MBS1 and MBS2 in the geographic information and other related information of Area1, indicating that both MBS1 and MBS2 are applicable to Area1, and includes the service identifier of MBS1 in the geographic information and other related information of Area2, indicating that MBS1 is applicable to Area2.

[0090] In this embodiment, the first information includes an allow identifier and / or an exclude identifier.

[0091] The "permit" identifier is used to indicate that a certain MBS service is permitted to be used in a certain area.

[0092] The exclusion option is used to indicate that a certain MBS service is not allowed to be used in a certain area.

[0093] Specifically, the first piece of information essentially indicates the correspondence between MBS services and regions; that is, it can indicate either the applicability of MBS services to regions or the inapplicability of MBS services to regions. In some cases, the indication implies applicability, and the absence of an indication implies inapplicability; this is the case in most of the embodiments listed in this application. However, in other cases, an indication is required regardless of applicability. In cases where an indication is required regardless of applicability, an allow flag and / or an exclude flag can be used for explicit representation.

[0094] For example, the current communication system includes three areas: Area1 and Area2, and two different MBS services: MBS1 and MBS2. MBS1 applies to Area1 and Area2, while MBS2 applies to Area1 but not Area2. The first information may include an allow flag and an exclude flag. For example, an allow flag is used for Area1 and Area2 to which MBS1 applies, indicating that MBS1 applies to Area1 and Area2. An allow flag is used for Area1 to which MBS2 applies, and an exclude flag is used for Area2 to which MBS2 does not apply, indicating that MBS2 applies to Area1 but not Area2. Or, for example, an allow flag is used for both MBS1 and MBS2 to indicate that both MBS1 and MBS2 apply to Area1. For Area2, an allow flag is used for MBS1 to indicate that MBS1 applies to Area2, and an exclude flag is used for MBS2 to indicate that MBS2 does not apply to Area2.

[0095] It should be noted that the area in this application embodiment can be one or more. Furthermore, the relationship between areas can be far apart, adjacent, or overlapping. For example, the current communication system includes three areas: Area1, Area2, and Area3, the overlapping area between Area1 and Area2. There are two different MBS services: MBS1 and MBS2. MBS1 applies to Area1 and Area2, while MBS2 applies to Area1 but not Area3. For MBS1, the first information can indicate that MBS1 applies to Area1 and Area2, or it can be indicated that MBS1 applies to Area1, Area2, and Area3. For MBS2, the first information can indicate that MBS2 applies to Area1 but excludes Area3.

[0096] It should be noted that the MBS service in this application embodiment can apply to one or more regions. Furthermore, a first piece of information can represent one region to which the MBS service applies, or it can represent multiple regions to which the MBS service applies simultaneously. When the first information represents multiple regions to which the MBS service applies simultaneously, a list of region identifiers can be used for representation. For example, the current communication system includes three areas: Area1, Area2, and one MBS service: MBS1. MBS1 applies to Area1 and Area2. For MBS1, the first information can be used to indicate that MBS1 applies to Area1 and Area2. Here, the first information can be represented as the area identifier of an applicable area. Then, MBS1 can be represented by two pieces of first information: one is the area identifier of Area1, and the other is the area identifier of Area2. The first information can also be represented as a list of applicable areas. Then, MBS1 can be represented by one piece of first information, which is a list of the area identifiers of Area1 and Area2. The list can be in the form of a bitmap, where different values ​​for each bit indicate whether the MBS service applies to the area corresponding to that bit. The bitmap form will be described in detail below.

[0097] It should be noted that multiple MBS services can run simultaneously in a communication system. The indication information can be an information concept specific to one MBS service. For example, an indication information indicates the area to which an MBS service is applicable. In a communication system that includes multiple MBS services, there will be multiple indication information. The indication information can also be a set of indication information for all MBS services.

[0098] In one embodiment, the region identifier may include a region ID (Cell ID) or a region index (Cell Index).

[0099] For example, for the MBS configuration information received by the UE, the coverage area of ​​the transmitting device that sends the MBS configuration information includes three areas: Area1, Area2 and Area3. The MBS service configuration information of the MBS service is applicable to Area1 and Area2. Then the indication information (first information) may include the area identifiers of Area1 and Area2.

[0100] For example, consider three different MBS services: MBS1, MBS2, and MBS3. For MBS1, the corresponding MBS service configuration information applies to Area 1; for MBS2, the corresponding MBS service configuration information applies to Area 1 and Area 2; and for MBS3, the corresponding MBS service configuration information does not apply to any area. Therefore, the indication information (first information) for MBS1 may include the area ID of Area 1, indicating that the corresponding MBS service configuration information for MBS1 applies to Area 1; the indication information (first information) for MBS2 may include the area IDs of Area 1 and Area 2, indicating that the corresponding MBS service configuration information for MBS2 applies to Area 1 and Area 2; and the indication information (first information) for MBS3 may not include any area ID, area index, or other area identifiers, indicating that the corresponding MBS service configuration information for MBS3 does not apply to any area.

[0101] In one embodiment, the region identifier may include a bitmap.

[0102] The total number of bits in the bitmap is equal to the total number of regions in the coverage area of ​​the transmitting device that sends the MBS configuration information; each bit in the bitmap corresponds sequentially to each region in the coverage area.

[0103] Accordingly, the indication information may include first information, and thus, the indication information may include a bitmap corresponding to the area indicated by the first information, and the MBS service is used to indicate whether it is applicable to the corresponding area by assigning a value to each bit in the bitmap.

[0104] For example, regarding the MBS configuration information received by the UE, if the coverage area of ​​the transmitting device sending the MBS configuration information includes three areas: Area1, Area2, and Area3, then the bitmap may have three bits: B2B1B0. These three bits are used to indicate whether the MBS service configuration information applies to each of these three areas. B2 is the most significant bit, and B0 is the least significant bit.

[0105] Each bit in the bitmap corresponds one-to-one with each region in sequence. This sequence includes: each bit in the bitmap is arranged from most significant bit to least significant bit or from least significant bit to most significant bit; and / or, each region is arranged according to its region identifier value, either from smallest to largest or from largest to smallest. Based on this, the correspondence between each bit and each region can have the following four possibilities:

[0106] Case 1: Each bit in the bitmap corresponds to each region arranged in ascending order of the region identifier values ​​from the most significant bit to the least significant bit. That is, B2, B1, and B0 correspond to Area1, Area2, and Area3, respectively.

[0107] Case 2: Each bit in the bitmap corresponds to each region arranged in ascending order of the region identifier values, from least to most significant bit. That is, B0, B1, and B2 correspond to Area1, Area2, and Area3, respectively.

[0108] Case 3: Each bit in the bitmap corresponds to each region arranged from high to low according to the region identifier values ​​from largest to smallest. That is, B2, B1, and B0 correspond to Area3, Area2, and Area1 respectively (the correspondence between each bit and each region is essentially the same as in Case 2).

[0109] Case 4: Each bit in the bitmap corresponds to each region arranged from the least significant bit to the most significant bit, according to the numerical values ​​of the region identifiers arranged from largest to smallest. That is, B0, B1, and B2 correspond to Area3, Area2, and Area1 respectively (the correspondence between each bit and each region is essentially the same as in Case 1).

[0110] Taking the bitmap corresponding to the region indicated by the first information as an example, the bitmap can be the three bits mentioned above: B2B1B0. The correspondence between each bit and each region may be any one of the above cases 1 to 4.

[0111] Taking a bitmap indicating whether the first information applies to the corresponding area of ​​the MBS service as an example, for the MBS configuration information received by the UE, the coverage area of ​​the transmitting device sending the MBS configuration information includes three areas: Area 1, Area 2, and Area 3. The MBS configuration information includes three different MBS services: MBS1, MBS2, and MBS3. For MBS1, the first information for MBS1 may include a bitmap B12B11B10, where B12 is the highest bit of the three bits, B10 is the lowest bit of the three bits, and the three bits are used to indicate whether the corresponding MBS service configuration information for MBS1 applies to these three areas. The correspondence between B12, B11, B10 and Area 1, Area 2, and Area 3 can be referred to the four cases mentioned above, and will not be repeated here; the indication information for the corresponding area of ​​the MBS service... MBS2 may include a bitmap B22B21B20, where B22 is the most significant bit and B20 is the least significant bit. These three bits are used to indicate whether the corresponding MBS service configuration information of MBS2 is applicable to these three areas. The correspondence between B22, B21, B20 and Area1, Area2, and Area3 can be referred to the four cases mentioned above, and will not be repeated here. The indication information for MBS3 may include a bitmap B32B31B30, where B32 is the most significant bit and B30 is the least significant bit. These three bits are used to indicate whether the corresponding MBS service configuration information of MBS3 is applicable to these three areas. The correspondence between B32, B31, B30 and Area1, Area2, and Area3 can be referred to the four cases mentioned above, and will not be repeated here.

[0112] In one embodiment, for a single bit in the bitmap of the first information: the bit takes a first value, indicating that the MBS service configuration information corresponding to the MBS service is applicable to the area corresponding to the bit; the bit takes a second value, indicating that the MBS service configuration information corresponding to the MBS service is not applicable to the area corresponding to the bit.

[0113] The first value can be 1, and the second value can be 0. Alternatively, the first value can be 0, and the second value can be 1.

[0114] For example, the bitmap of the first information has three bits: B2B1B0. These three bits are used to indicate whether the MBS configuration information applies to Area1, Area2, and Area3, respectively. Taking a first value of 1 and a second value of 0 as an example, if the MBS configuration information applies to Area1 and Area2, then the bitmap of the first information can be 110.

[0115] In some embodiments, for a single MBS service, if the corresponding MBS service configuration information is not applicable to any region, for example, for MBS3 mentioned above, the corresponding MBS service configuration information is not applicable to any region, then the indication information (first information) may not include the corresponding bitmap (B32B31B30).

[0116] In other embodiments, the area identifier may take other forms, which will not be listed here.

[0117] In this embodiment, the indication information may include first information and / or second information; correspondingly, the indication information may include the area identifier of the area indicated by the first information, and / or the content identifier of the content indicated by the second information for the MBS service.

[0118] In this embodiment, the second information includes the content identifier.

[0119] In one embodiment, the content identifier can be a content ID or a content index.

[0120] For example, regarding the MBS configuration information received by the UE, the MBS configuration information includes two different MBS services: MBS4 and MBS5. MBS4 is divided into two contents, Content1 and Content2, while MBS5 is a single service. Therefore, the indication information (second information) for Content1 of MBS4 may include the Content1 content ID, used to indicate the MBS service configuration information of Content1 of MBS4 to the UE. Content1 can be received according to this MBS service configuration information. Similarly, the indication information (second information) for Content2 of MBS4 may include the Content2 content ID, used to indicate the MBS service configuration information of Content2 of MBS4 to the UE. Content2 can be received according to this MBS service configuration information. The indication information (second information) for MBS5 may include content identifiers such as content ID and content index, or may include an MBS5 identifier, used to indicate the MBS service configuration information of MBS5 to the UE. The complete MBS5 can be received according to this MBS service configuration information.

[0121] In one embodiment, the content identifier can be a bitmap.

[0122] Specifically, the content of the MBS service is represented by assigning a value to each bit in the bitmap, or it is referred to as representing the content corresponding to the current MBS service configuration information by assigning a value to each bit in the bitmap.

[0123] In this case, the total number of bits in the bitmap is equal to the total number of MBS service contents within the coverage area of ​​the transmitting device that sends the MBS configuration information, and each bit in the bitmap corresponds sequentially to each content in the coverage area; the total number of bits in the bitmap can also be equal to the total number of MBS service contents within the area receiving the MBS configuration information, and each bit in the bitmap corresponds sequentially to each content in the receiving area; the total number of bits in the bitmap can also be equal to the total number of contents in the corresponding MBS service, and each bit in the bitmap corresponds sequentially to each content in the corresponding MBS service.

[0124] For example, regarding the MBS configuration information received by the UE, if the coverage area sending the MBS configuration information includes an MBS service, and the content of the MBS service includes Content1, Content2, and Content3, then the bitmap may have three bits: B2B1B0. These three bits are used to indicate the content of the MBS service, or in other words, they are used to indicate which content the MBS service configuration information represents. B2 is the most significant bit, and B0 is the least significant bit.

[0125] Each bit in the bitmap corresponds sequentially to a specific content element. This sequence includes either moving the bits from most significant bit to least significant bit or vice versa; and / or, assigning each content element its content identifier value in ascending or descending order. Based on this, the correspondence between each bit and each content element can have the following four possibilities:

[0126] Case 1: Each bit in the bitmap corresponds to each content in ascending order of the content identifier value, from the most significant bit to the least significant bit. That is, B2, B1, and B0 correspond to Content1, Content2, and Content3, respectively.

[0127] Case 2: Each bit in the bitmap corresponds to each content in ascending order of its content identifier value, from least significant bit to most significant bit. That is, B0, B1, and B2 correspond to Content1, Content2, and Content3, respectively.

[0128] Case 3: Each bit in the bitmap corresponds to each content in descending order of the content identifier value, from the most significant bit to the least significant bit. That is, B2, B1, and B0 correspond to Content3, Content2, and Content1 respectively (the correspondence between each bit and each content is essentially the same as in Case 2).

[0129] Case 4: Each bit in the bitmap corresponds to each content in descending order of the content identifier value, from least significant bit to most significant bit. That is, B0, B1, and B2 correspond to Content3, Content2, and Content1 respectively (the correspondence between each bit and each content is essentially the same as in Case 1).

[0130] Taking the bitmap corresponding to the content indicated by the first information as an example, the bitmap can be the three bits mentioned above: B2B1B0. The correspondence between each bit and each content may be any one of the above cases 1 to 4.

[0131] Taking the bitmap indicating whether the second information applies to the MBS service as an example, for the MBS configuration information received by the UE, the coverage area of ​​sending the MBS configuration information includes an MBS service. The content of the MBS service includes Content1, Content2, and Content3. For Content1, the indication information (second information) can include a bitmap B12B11B10, where B12 is the highest bit of the three bits and B10 is the lowest bit of the three bits. These three bits are used to jointly indicate that the current content is Content1 (i.e., the current MBS service configuration information is Content1). The correspondence between B12, B11, B10 and Content1, Content2, and Content3 can be referred to the four cases mentioned above, which will not be repeated here. For Content2, the indication information (second information) can include a bitmap B22B10. 21B20, where B22 is the most significant bit of the three bits and B20 is the least significant bit of the three bits. These three bits are used to jointly indicate that the current content is Content2 (i.e., the current MBS service configuration information is Content2). The correspondence between B22, B21, B20 and Content1, Content2, and Content3 can be referred to the four cases mentioned above, and will not be repeated here. The indication information (second information) for Content3 may include a bitmap B32B31B30, where B32 is the most significant bit of the three bits and B30 is the least significant bit of the three bits. These three bits are used to jointly indicate that the current content is Content3 (i.e., the current MBS service configuration information is Content3). The correspondence between B32, B31, B30 and Area1, Area2, and Area3 can be referred to the four cases mentioned above, and will not be repeated here.

[0132] In one embodiment, for a single bit in the bitmap of the second information: the bit takes a first value, indicating that it corresponds to the content of the MBS service corresponding to the bit, that is, the current MBS service configuration information is the configuration information of the content corresponding to the bit; the bit takes a second value, indicating that it does not correspond to the content of the MBS service corresponding to the bit, that is, the current MBS service configuration information is not the configuration information of the content corresponding to the bit.

[0133] The first value can be 1, and the second value can be 0. Alternatively, the first value can be 0, and the second value can be 1.

[0134] For example, the bitmap of the second information has three bits: B2B1B0. These three bits are used sequentially to represent the content of the corresponding MBS service, i.e., whether the current MBS service configuration information is Content1, Content2, or Content3. Taking a first value of 1 and a second value of 0 as an example, when the MBS service content is Content1 and the MBS service configuration information is Content1, the bitmap of the second information can be 001; when the MBS service content is Content2 and the MBS service configuration information is Content2, the bitmap of the second information can be 010; when the MBS service content is Content3 and the MBS service configuration information is Content3, the bitmap of the second information can be 100.

[0135] In some embodiments, for a single MBS service, if the corresponding MBS service configuration information is not applicable to any content, the indication information (second information) may not include the corresponding bitmap.

[0136] In other embodiments, the content identifier may take other forms, which will not be listed here.

[0137] It should be noted that when the indication information includes the second information, the second information may include the content identifier of the content indicated for one, multiple or all MBS services. That is, the second information may include the content identifier of the content indicated for each MBS service of the UE, or it may include the content identifier of the content indicated for some MBS services of the UE.

[0138] In one embodiment, the second information may include a content identifier, may include a service identifier for the MBS service, and may also include both the content identifier and the service identifier.

[0139] In other words, the UE can directly determine the content of the MBS service through the content identifier (which can also be referred to as the content corresponding to the MBS service configuration information of the MBS service), directly determine the content of the MBS service through the service identifier, or determine the content of the MBS service through both the content identifier and the service identifier of the MBS service.

[0140] For example, when the content identifier is a content ID, for the MBS configuration information received by the UE, the MBS configuration information includes two different MBS services: MBS6 and MBS7. MBS6 is divided into two contents, and MBS7 is divided into three contents. Therefore, when indicating via the second information, only the content identifiers are used to indicate the two contents of MBS6 and the three contents of MBS7. That is, for the first content of MBS6, the content identifier is recorded as Content1; for the second content of MBS6, the content identifier is recorded as Content2; for the first content of MBS7, the content identifier is recorded as Content3; for the second content of MBS7, the content identifier is recorded as Content4; and for the third content of MBS7, the content identifier is recorded as Content5. t5, correspondingly, when an MBS service configuration information includes Content1, it can be said that the MBS service configuration information is the configuration information of Content1; when an MBS service configuration information includes Content2, it can be said that the MBS service configuration information is the configuration information of Content2; when an MBS service configuration information includes Content3, it can be said that the MBS service configuration information is the configuration information of Content3; when an MBS service configuration information includes Content4, it can be said that the MBS service configuration information is the configuration information of Content4; when an MBS service configuration information includes Content5, it can be said that the MBS service configuration information is the MBS service configuration information of Content5.

[0141] For example, when the content identifier is the area ID, for the MBS configuration information received by the UE, the MBS configuration information includes two different MBS services: MBS6 and MBS7. MBS6 is divided into two contents, and MBS7 is divided into three contents. When indicating through the second information, the content identifier and the service identifier can be used together to indicate the two contents of MBS6 and the three contents of MBS7. That is, for the first content of MBS6, the content identifier is recorded as Content1; for the second content of MBS6, the content identifier is recorded as Content2; for the first content of MBS7, the content identifier is recorded as Content1; for the second content of MBS7, the content identifier is recorded as Content2; and for the third content of MBS7, the content identifier is recorded as Content3. Accordingly, when an MBS service configuration information includes an MBS6 service identifier and Content1, it can indicate that the MBS service configuration information is the configuration information of the first content of MBS6, Content1; when an MBS service configuration information includes an MBS6 service identifier and Content2, it can indicate that the MBS service configuration information is the configuration information of the second content of MBS6; when an MBS service configuration information includes an MBS7 service identifier and Content1, it can indicate that the MBS service configuration information is the configuration information of the first content of MBS7; when an MBS service configuration information includes an MBS7 service identifier and Content2, it can indicate that the MBS service configuration information is the configuration information of the second content of MBS7; and when an MBS service configuration information includes an MBS7 service identifier and Content3, it can indicate that the MBS service configuration information is the configuration information of the third content of MBS7.

[0142] For example, when the content identifier is a bitmap, for the MBS configuration information received by the UE, the MBS configuration information includes two different MBS services: MBS6 and MBS7. MBS6 is divided into two contents, and MBS7 is divided into three contents. When indicating via the second information, only the content identifier is used to indicate the two contents of MBS6 and the three contents of MBS7. The total number of bits is the total number of contents of all MBS services within the coverage area of ​​the transmitting device sending the MBS configuration information. Based on the above embodiment, each bit is assigned a value of 1 for the first value and 0 for the second value. That is, for the first content of MBS6, the content identifier is recorded as 00001; for the second content of MBS6, the content identifier is recorded as 00010; for the first content of MBS7, the content identifier is recorded as 00100; for the second content of MBS7, the content identifier is recorded as 01000; and so on. The third content of MBS7 is identified by the content identifier 10000. Correspondingly, when an MBS service configuration information includes the content identifier 00001, it can indicate that the MBS service configuration information is the configuration information of the first content of MBS6; when an MBS service configuration information includes the content identifier 00010, it can indicate that the MBS service configuration information is the configuration information of the second content of MBS6; when an MBS service configuration information includes the content identifier 00100, it can indicate that the MBS service configuration information is the configuration information of the first content of MBS7; when an MBS service configuration information includes the content identifier 01000, it can indicate that the MBS service configuration information is the configuration information of the second content of MBS7; and when an MBS service configuration information includes the content identifier 10000, it can indicate that the MBS service configuration information is the configuration information of the third content of MBS7.

[0143] For example, when the content identifier is a bitmap, for the MBS configuration information received by the UE, the MBS configuration information includes two different MBS services: MBS6 and MBS7. MBS6 is divided into two contents, and MBS7 is divided into three contents. When indicating through the second information, the content identifier and the service identifier can be used together to indicate the two contents of MBS6 and the three contents of MBS7. The total number of bits is the total number of contents in the corresponding MBS service. Based on the above embodiment, each bit is assigned a value of 1 for the first value and 0 for the second value. That is, for the first content of MBS6, the content identifier is recorded as 01; for the second content of MBS6, the content identifier is recorded as 10; for the first content of MBS7, the content identifier is recorded as 001; for the second content of MBS7, the content identifier is recorded as 010; and for the third content of MBS7, the content identifier is recorded as 100. Accordingly, when an MBS service configuration information includes an MBS6 service identifier and a content identifier 01, it can indicate that the MBS service configuration information is the configuration information of the first content of MBS6; when an MBS service configuration information includes an MBS6 service identifier and a content identifier 10, it can indicate that the MBS service configuration information is the configuration information of the second content of MBS6; when an MBS service configuration information includes an MBS7 service identifier and a content identifier 001, it can indicate that the MBS service configuration information is the configuration information of the first content of MBS7; when an MBS service configuration information includes an MBS7 service identifier and a content identifier 010, it can indicate that the MBS service configuration information is the configuration information of the second content of MBS7; and when an MBS service configuration information includes an MBS7 service identifier and a content identifier 100, it can indicate that the MBS service configuration information is the configuration information of the third content of MBS7.

[0144] In one embodiment, MBS services include multicast services that can be received by a UE in the RRC_CONNECTED state.

[0145] In this embodiment, for multicast services that can be received by a UE in the RRC_CONNECTED state, the UE can, according to the indication information, receive the multicast service in the area applicable to the multicast service (or in the area applicable to the MBS service configuration information corresponding to the multicast service) based on the MBS configuration information (or based on the MBS service configuration information corresponding to the multicast service) while in the RRC_CONNECTED state; and / or the UE can, according to the indication information, receive the content of the multicast service (or in the area applicable to the MBS service configuration information corresponding to the content of the multicast service) based on the MBS configuration information (or based on the MBS service configuration information corresponding to the content of the multicast service) while in the RRC_CONNECTED state.

[0146] In one embodiment, the MBS service includes a multicast service that can be received by a UE in the RRC_INACTIVE state.

[0147] In this embodiment, for multicast services that can be received by a UE in the RRC_INACTIVE state, the UE can, according to the indication information, receive the multicast service in the area applicable to the multicast service (or in the area applicable to the MBS service configuration information corresponding to the multicast service) based on the MBS configuration information (or based on the MBS service configuration information corresponding to the multicast service) when in the RRC_INACTIVE state; and / or the UE can, according to the indication information, receive the content of the multicast service (or in the area applicable to the MBS service configuration information corresponding to the content of the multicast service) based on the MBS configuration information (or based on the MBS service configuration information corresponding to the content of the multicast service) when in the RRC_INACTIVE state.

[0148] In one embodiment, the MBS service includes broadcast services that can be received by a UE in the RRC_CONNECTED, RRC_INACTIVE, or RRC_IDLE state.

[0149] In this embodiment, for broadcast services that can be received by a UE in the RRC_CONNECTED, RRC_INACTIVE, or RRC_IDLE states, the UE can, according to the indication information, receive the broadcast service in the area applicable to the broadcast service (or in the area applicable to the MBS service configuration information corresponding to the broadcast service) based on the MBS configuration information (or based on the MBS service configuration information corresponding to the broadcast service) while in the RRC_CONNECTED, RRC_INACTIVE, or RRC_IDLE states; and / or the UE can, according to the indication information, receive the content of the broadcast service (or in the area applicable to the MBS service configuration information corresponding to the content of the broadcast service) based on the MBS configuration information (or based on the MBS service configuration information corresponding to the content of the broadcast service) while in the RRC_CONNECTED, RRC_INACTIVE, or RRC_IDLE states.

[0150] In one embodiment, the area may include a coverage area in the NTN network and / or an area in an NTN cell.

[0151] Specifically, the area can include the area covered by the transmitting device connected to the NTN network, or the area within an NTN cell covered by the transmitting device connected to the NTN network. There can be one or more areas within an NTN cell, and the NTN cell can be divided into multiple areas based on factors such as geographical location and transmitted content.

[0152] In one embodiment, the geographic location information of the region may include circular region information, and / or polygonal region information and / or other types of region information. The circular region information may include reference location information, and / or region identifiers, and / or distance information. The polygonal region information may at least include a region identifier.

[0153] Specifically, the UE can determine its current geographical location through various means such as self-positioning or information transmission, and then determine which area its current geographical location falls within. Thus, the UE can determine its location and, based on the indication information, determine the MBS services that can be received in that area, thereby enabling the reception of MBS services.

[0154] In one embodiment, the geographic location information of a region can be carried by system messages, configuration information, or other messages.

[0155] The system messages here may include existing system message blocks, NTN system message blocks, MBS system message blocks, and new system message blocks, which will not be listed here.

[0156] Other messages here may include MBS configuration information, RRC reconfiguration or RRC connection release messages, or other types of information. MBS configuration information includes MBS broadcast configuration information, MBS multicast configuration information, MBS service configuration information, etc., which will not be listed here.

[0157] Specifically, the indication information indicates the area to which the MBS service applies, and the geographical location information of the area indicates the actual coverage of the area. Thus, the UE can determine the area to which the MBS service applies based on the geographical location information of the area, the MBS service, and the indication information. In actual operation, after receiving the MBS configuration information, the UE can determine the actual area to which the MBS service configuration information corresponding to one or more MBS services included in the MBS configuration information applies, using the indication information and the geographical location information of the area. Accordingly, UEs within the geographical location information of that area can use the corresponding MBS service configuration information to receive the corresponding MBS service.

[0158] In one embodiment, the indication information is essentially used to indicate the applicable relationship between MBS services and regions, thus the indication information (first information) essentially includes

[0159] Business identifier, and / or;

[0160] Area identifier, and / or;

[0161] Geographical location information of the region.

[0162] Specifically, the MBS service is represented by a service identifier, the region identifier is represented by a region, and the geographic location information of the region is used to indicate the actual coverage area of ​​the region. By combining the correspondence between the service identifier, the region identifier, and the geographic location information of the region, the actual coverage area of ​​the region to which the MBS service applies can be represented, or the MBS service applicable within the actual coverage area of ​​the region.

[0163] Accordingly, after obtaining the indication information (first information), the UE can receive and / or decode the corresponding MBS service in the corresponding area, and will not receive and / or decode the corresponding MBS service in the non-corresponding area.

[0164] In one embodiment, the indication information may be carried by an RRC connection release message containing suspend configuration information.

[0165] Specifically, the RRC connection release message (RRCRelease Message with suspendconfig) includes suspend configuration information and MBS configuration information (e.g., MBSMulticastConfiguration message). The MBS configuration information indicates the configuration information of multicast services that can be received by the UE in the RRC_INACTIVE state, and the suspend configuration information indicates the UE's handover from RRC_CONNECTED to RRC_INACTIVE. When the indication information is carried by an RRC connection release message (RRCRelease Message with suspendconfig) containing suspend configuration information, the indication information can be included in one of the following configuration information in the RRC connection release message containing suspend configuration information: suspend configuration information; MBS configuration information; configuration information other than suspend configuration information; or configuration information other than MBS configuration information. That is, in this embodiment, the indication information can be included within the suspend configuration information, or included outside the suspend configuration information, or included within the MBS configuration information, or included outside the MBS configuration information.

[0166] In one embodiment, the MBS service configuration information corresponding to each MBS service in the MBS configuration information includes at least the service identifier corresponding to each MBS service. The service identifier can be a session ID, a G-RNTI (Group-RNTI Radio Network Temporary Identity), or a TMGI (Temporary Mobile Group Identity).

[0167] In this embodiment, for each MBS service, the MBS service configuration information corresponding to that MBS service includes at least the service identifier of that MBS service. Furthermore, it may also include all or part of the MBS service configuration information corresponding to that MBS service. For example, when the UE transitions from the RRC_CONNECTED state to the RRC_CONNECTED state, for MBS services received in the RRC_CONNECTED state, the MBS configuration information may not change after the transition to the RRC_CONNECTED state. In this case, the MBS service configuration information corresponding to that MBS service may only include the corresponding service identifier. However, if the MBS configuration information changes, the MBS service configuration information corresponding to that MBS service may also include the changed MBS configuration information (such as changed configuration parameters), or it may include all the MBS service configuration information corresponding to that MBS service.

[0168] In one embodiment, the indication information may be carried by an RRC reconfiguration message.

[0169] The RRC reconfiguration message can carry MBS configuration information or indication information. Furthermore, the indication information can be included within the MBS configuration information carried by the RRC reconfiguration message; for example, the indication information can be included within the MBS configuration information carried by the RRC reconfiguration message, or it can be included within other information carried by the RRC reconfiguration message.

[0170] In one embodiment, the indication information may be carried by multicast MCCH messages, broadcast MCCH messages, system messages, proprietary signaling, or other information.

[0171] In one embodiment, the indication information may be carried by a multicast MCCH message.

[0172] The multicast MCCH message can carry MBS configuration information or indication information. Furthermore, the indication information can be included within the MBS configuration information carried by the multicast MCCH message; for example, the indication information can be included within the MBS configuration information carried by the multicast MCCH message, or it can be included within other information carried by the multicast MCCH message.

[0173] In one embodiment, the indication information may be carried by a broadcast MCCH message.

[0174] The broadcast MCCH message can carry MBS configuration information or indication information. Furthermore, the indication information can be included within the MBS configuration information carried by the broadcast MCCH message. For example, the indication information can be included within the MBS configuration information carried by the broadcast MCCH message, or it can be included within other information carried by the broadcast MCCH message.

[0175] In one embodiment, the indication information may be carried by a system message.

[0176] System messages can include MBS system information blocks, NTN system message blocks, 3GPP RELEASE 19 newly added system message blocks, or other system message blocks. Furthermore, indication information can be included within the MBS system information block of a system message; for example, indication information can be included in MBS configuration information within the MBS system information block, within the NTN system message block of a system message, or within a dedicated system message block dedicated to carrying indication information. It can also be included within other system message blocks carried by the system message.

[0177] In one embodiment, the indication information may be carried by proprietary signaling.

[0178] The proprietary signaling can carry only indication information, or it can carry other information, such as MBS configuration information. Furthermore, the indication information can be included in other information carried by proprietary signaling; for example, the indication information can be included in the MBS configuration information carried by proprietary signaling, or it can be included in other information carried by proprietary signaling.

[0179] It should be noted that the instruction information can consist of multiple pieces of information, and thus, multiple pieces of information in the instruction information can be carried by different information at the same time.

[0180] When the instruction information includes a business identifier, a region identifier, and the region's geographic location information simultaneously:

[0181] In the first scenario, the service identifier and region identifier are included in the MBS configuration information, while the region's geographic location information can be included in other information, such as system messages.

[0182] The second scenario is that the service identifier, the region identifier, and the region's geographic location information can all contain other information, such as various system message blocks in the system messages. At the same time, the service identifier is also included in the MBS configuration information.

[0183] The second scenario is that the business identifier, the region identifier, and the geographical location information of the region can all contain other information, such as the various system message blocks in the system message. At the same time, the business identifier and the region identifier are also included in the MBS configuration information.

[0184] There are other situations as well, which will not be listed here.

[0185] For example, the current communication system includes three areas: Area 1 and Area 2, and two different MBS services: MBS1 and MBS2. MBS1 is applicable to Area 1 and Area 2, while MBS2 is applicable to Area 1.

[0186] Based on the first scenario described above, the MBS configuration information includes, for MBS1, the MBS1 service identifier and its corresponding Area1 and Area2 area identifiers; for MBS2, the MBS2 service identifier and its corresponding Area1 area identifier; and the system message includes the geographic location information of Area1 and Area2.

[0187] Based on the second scenario described above, the MBS configuration information includes the MBS1 service identifier for MBS1 and the MBS2 service identifier for MBS2. In the system message, for Area1, it includes the Area1 area identifier and its corresponding MBS1 service identifier, the corresponding MBS2 service identifier, and the geographical location information of Area1. For Area2, it includes the Area2 area identifier and its corresponding MBS1 service identifier, and the geographical location information of Area2.

[0188] Based on the second scenario described above, the MBS configuration information includes, for MBS1, the MBS1 service identifier and its corresponding Area1 and Area2 area identifiers; for MBS2, the MBS2 service identifier and its corresponding Area1 area identifier; in the system message, for Area1, the Area1 area identifier and its corresponding MBS1 service identifier, the corresponding MBS2 service identifier, and the Area1 geographical location information; for Area2, the Area2 area identifier and its corresponding MBS1 service identifier, and the Area2 geographical location information.

[0189] There are other situations as well, which will not be listed here.

[0190] In one embodiment, the indication information may be located in the MBS configuration information.

[0191] Considering that the MBS configuration information includes both MBS service configuration information and other configuration information, the indication information can be located either within the MBS service configuration information or within other configuration information within the MBS configuration information.

[0192] Considering that the indication information may include multiple different pieces of information, there are several possibilities when the indication information is located in the MBS configuration information. For example, if the indication information includes a service identifier, a region identifier, and the region's geographic location information, and the service identifier and region identifier are located in the MBS configuration information, one possibility is that both the service identifier and the region identifier can be included in the MBS service configuration information of the MBS configuration information; another possibility is that the service identifier can be located in the MBS service configuration information of the MBS configuration information, and the region identifier can be located in the configuration information of the MBS configuration information other than the MBS service configuration information.

[0193] It should be noted that the MBS service configuration information of existing MBS services already contains a service identifier. This service identifier is used to indicate which MBS service the MBS service configuration information belongs to. However, in the embodiments of this application, when the indication information includes information such as a service identifier and a region identifier, and when the service identifier and region identifier are located in the MBS service configuration information, the MBS service configuration information usually does not add a new service identifier on the basis of the existing service identifier, but adds a region identifier. However, the existing service identifier can be associated with the region identifier to indicate that the MBS service corresponding to the service identifier is applicable to the region corresponding to the region identifier.

[0194] In this embodiment, the inclusion of indication information in MBS configuration information can mean that some information in the indication information can be included in the MBS configuration information, or that all information in the indication information can be included in the MBS configuration information. The MBS configuration information includes at least some of the information in the indication information. For example, it could be in a system message; alternatively, the service identifier, region identifier, and the region's geographic location information could all be included in the system message, while the service identifier is also included in the MBS configuration information. In other words, in this embodiment, the inclusion of indication information in MBS configuration information means that the MBS configuration information includes at least some of the information in the indication information.

[0195] In one embodiment, if the indication information contains an information portion within the MBS configuration information, it can be sent to the user equipment together with the indication information. For example, the indication information can be included in the MBS configuration information, and the MBS configuration information can be sent to the user equipment. Alternatively, the MBS configuration information and the indication information can be sent to the user equipment separately.

[0196] In this embodiment, the MBS configuration information includes MBS service configuration information (e.g., MBS-SessionInformationListMulticast, MBSSessionInformationList). The indication information may include first information, which may be included in the MBS configuration information but outside of the MBS service configuration information; the indication information may also include second information, which may be included in the MBS service configuration information.

[0197] For example, the indication information can be carried by a multicast MCCH message. In the case where the indication information only contains first information, which includes a region identifier, a service identifier, and region geographic location information, the region identifier and region geographic location information are in the system message, and the region identifier and service identifier are in the MBS configuration information and in the MBS service configuration information.

[0198] The data structure of system messages is as follows:

[0199] In the system message SIBX-r19, ntn-AreaId-r19 is used to represent the area identifier, ntn-ReferenceLocation-r1 and ntn-DistanceRadius are the geographic location information of the area, ntn-ReferenceLocation-r19 is used to represent the reference location information, and ntn-DistanceRadius is used to represent the distance information.

[0200] The data structure of MBS configuration information is as follows:

[0201] In the MBS configuration information, MBSMulticastConfiguration-r18 is the MBS configuration information, MBS-SessionInfoListMulticast-r18 is the MBS service configuration information, g-RNTI-r18 is the service identifier, and areaIDx1, areaIDx2, ..., areaIDx... n It is the area identifier for the region where MBS services are applicable.

[0202] In this example, the MBS configuration information includes area IDs areaIDx1, areaIDx2, ..., areaIDx. n The value can be ntn-AreaId-r19 from the system message SIBX-r19.

[0203] In this example, the MBS configuration information includes area IDs areaIDx1, areaIDx2, ..., areaIDx. n The corresponding geographic location information can be obtained from ntn-ReferenceLocation-r19 and ntn-DistanceRadius-r19 in the system message SIBX-r19.

[0204] For example, the indication information can be carried by a multicast MCCH message. In the case where the indication information includes first information and second information, and the first information includes a region identifier and a service identifier, wherein the region identifier and service identifier are both in the MBS configuration information and in the MBS service configuration information, the data structure of the MBS configuration information is as follows:

[0205] In the MBS configuration information, MBSMulticastConfiguration-r18 is the MBS configuration information, MBS-SessionInfoListMulticast-r18 is the MBS service configuration information, g-RNTI-r18 is the service identifier, areaID is the area identifier of the region to which the MBS service applies, and content ID is the content identifier.

[0206] For example, the indication information can be carried by a multicast MCCH message. The indication information contains only first information, which is only included in the MBS service configuration information. The data structure of the MBS configuration information is as follows:

[0207] In the MBS configuration information, MBSMulticastConfiguration-r18 is the MBS configuration information, MBS-SessionInfoListMulticast-r18 is the MBS service configuration information, g-RNTI-r18 is the service identifier, and areaID is the area identifier of the region to which the MBS service applies.

[0208] For example, the indication information can be carried by a multicast MCCH message. The indication information contains only the first information and is included in the MBS configuration information but outside the MBS service configuration information. The data structure of the MBS configuration information is as follows:

[0209] In the MBS configuration information, MBSMulticastConfiguration-r18 is the MBS configuration information, MBS-SessionInfoListMulticast-r18 is the MBS service configuration information, g-RNTI-r18 is the service identifier, and areaID is the area identifier of the region to which the MBS service applies.

[0210] For example, the indication information can be carried by a multicast MCCH message. The indication information contains only the second information and is included within the MBS service configuration information. The data structure of the MBS configuration information is as follows:

[0211] In the MBS configuration information, MBSMulticastConfiguration-r18 is the MBS configuration information, MBS-SessionInfoListMulticast-r18 is the MBS service configuration information, g-RNTI-r18 is the service identifier, and content ID is the content identifier of the MBS service.

[0212] For example, the indication information can be carried by a multicast MCCH message. In the case where the indication information includes first information and second information, the first information is included in the MBS configuration information but is separate from the MBS service configuration information, while the second information is included in the MBS configuration information but is also present in the MBS service configuration information. The data structure of the MBS configuration information is as follows:

[0213] In the MBS configuration information, MBSMulticastConfiguration-r18 is the MBS configuration information, MBS-SessionInfoListMulticast-r18 is the MBS service configuration information, g-RNTI-r18 is the service identifier, areaID is the area identifier applicable to the MBS service, and content ID is the content identifier of the MBS service.

[0214] For example, the indication information can be carried by a broadcast MCCH message. The indication information contains only the first information, and this first information is included in the MBS configuration information and also in the MBS service configuration information. The data structure of the MBS configuration information is as follows:

[0215] Among them, MBSBroadcastConfiguration-r17 is MBS configuration information, MBS-SessionInfoList-r17 is MBS service configuration information, g-RNTI-r18 is service identifier, and areaID is the area identifier applicable to MBS service.

[0216] For example, the indication information can be carried by a broadcast MCCH message. The indication information contains only the first information, and this first information is included in the MBS configuration information but not in the MBS service configuration information. The data structure of the MBS configuration information is as follows:

[0217] Among them, MBSBroadcastConfiguration-r17 is MBS configuration information, MBS-SessionInfoList-r17 is MBS service configuration information, g-RNTI-r18 is service identifier, and areaID is the area identifier applicable to MBS service.

[0218] For example, the indication information can be carried by a broadcast MCCH message. The indication information contains only the second information, and this second information is included in the MBS service configuration information within the MBS configuration information. The data structure of the MBS configuration information is as follows:

[0219] Among them, MBSBroadcastConfiguration-r17 is MBS configuration information, MBS-SessionInfoList-r17 is MBS service configuration information, and content ID is the content identifier of the second information.

[0220] For example, the indication information can be carried by a broadcast MCCH message. If the indication information includes both first and second information, both the first and second information are included in the MBS configuration information and also in the MBS service configuration information. The data structure of the MBS configuration information is as follows:

[0221] Among them, MBSBroadcastConfiguration-r17 is MBS configuration information, MBS-SessionInfoList-r17 is MBS service configuration information, areaID is the area identifier of the first information, and content ID is the content identifier of the second information.

[0222] It should be noted that the above are merely examples of situations where the indication information is carried by multicast MCCH messages, broadcast MCCH messages, system messages or other messages. There may be other situations where the first information and / or the second information are located in the MBS configuration information, which will not be listed here.

[0223] It should be noted that the above is only an example of the content of the first information. The first information may include the region identifier and / or the service identifier and / or the geographic location information of the region. The first information may also include other information. Therefore, there are other situations regarding the location of the first information. For example, the geographic location information of the region may be located in the system message, and the region identifier and the service identifier may both be located in the MBS configuration information. Or, the region identifier, the service identifier, and the geographic location information of the region may all be located in the system message, and the region identifier and the service identifier may both be located in the MBS configuration information. These will not be listed one by one here.

[0224] It should be noted that the names and data structures of the first and second information in the above data structures are for illustrative purposes only. In practice, they can also have other names and structures, and this embodiment does not limit them. Furthermore, all parts except the instruction message used to indicate the area can be changed and replaced according to actual application scenarios and needs, and this embodiment does not limit them.

[0225] In one embodiment, the first information can be used to represent the correspondence between regions and MBS services. For a single region or MBS service, the applicable MBS service in the region can be determined based on the first information.

[0226] It should be noted that the area to which MBS services are applicable, or the MBS services applicable within a region, essentially refers to which one or more MBS services can be received in which one or more regions. Therefore, in the embodiments of this application, for the sake of brevity, only "MBS services applicable within the region" is usually described, but this actually also implies a description of "the area to which MBS services are applicable".

[0227] In one embodiment, for a single region, the first information may be included in the associated information corresponding to the region to indicate the MBS service applicable to the region indicated by the first information.

[0228] Specifically, when the first information indicates the applicable MBS service in the region, for example, if the service identifier in the first information is included in the geographical location information of the region, for that region, the UE located in that region can use the MBS service configuration information to receive the MBS service corresponding to the service identifier.

[0229] In one embodiment, for a single MBS service, the first information may be included in the associated information corresponding to the MBS service to indicate that the MBS service is applicable to the area indicated by the first information.

[0230] Specifically, when the first information indicates the area to which the MBS service applies, the first information may include one or more area identifiers. For example, the area identifier in the first information may be included in the MBS service configuration information of the MBS service. For the MBS service, the UE may receive the corresponding MBS service in the area corresponding to the area identifier using the corresponding MBS service configuration information.

[0231] For example, the current communication system includes three areas: Area1, Area2, and Area3, and two services, MBS1 and MBS2. MBS1 applies to Area1 and Area2, while MBS2 applies to Area1. The area identifiers of Area1 and Area2 can be included in the MBS service configuration information of MBS1, and the area identifier of Area1 can be included in the MBS service configuration information of MBS2. Thus, when the UE receives the MBS configuration information, for MBS1, it can receive MBS1 in Area1 and Area2 based on the area identifiers of Area1 and Area2 in the MBS service configuration information of MBS1, and for MBS2, it can receive MBS2 in Area1 based on the area identifier of Area1 in the MBS service configuration information of MBS2.

[0232] Additionally, it should be noted that when the UE receives the MBS service based on its MBS service configuration information, it considers both the MBS service configuration information itself and common information within the MBS configuration information (excluding the MBS service configuration information for all MBS services). Therefore, this MBS service is applicable to the area indicated by the first information, and its MBS service configuration information is also applicable to the area indicated by the first information. The common information within the MBS configuration information (excluding the MBS service configuration information for all MBS services) can be applied to even more areas.

[0233] In one embodiment, for a single MBS service, if the first information is not included in the MBS service configuration information corresponding to the MBS service, the MBS service may be applicable to all or part of the area of ​​the cell that sends the MBS service, or may not be applicable to any area of ​​the cell.

[0234] For example, for MBS1, if the first information is not included in the MBS service configuration information corresponding to the MBS1 service, then one scenario is that the area applicable to the MBS service configuration information corresponding to MBS1 is the area of ​​the cell that sent MBS1. If the UE receives the MBS configuration information in Area 1 of Cell 1, then the MBS service configuration information corresponding to MBS1 applies to all or some areas in Cell 1, and the UE can receive MBS1 from all or some areas in Cell 1 based on the MBS service configuration information corresponding to MBS1. Another scenario is that the MBS service configuration information corresponding to MBS1 does not apply to any area, and the UE will not receive MBS1 based on the MBS service configuration information corresponding to MBS1 in any area.

[0235] It should be noted that when MBS service applies to all areas of the cell that sends MBS service, the cell here can be the cell that sends MBS service, the cell that sends MBS configuration information, the cell that receives MBS configuration information, or the cell that sends system messages carrying scheduling information carrying MBS configuration information.

[0236] For a single MBS service, if the first information is not included in the MBS service configuration information corresponding to the MBS service, or if the first information is included in the MBS configuration information other than the MBS service configuration information corresponding to all MBS services, then the MBS service is applicable to the area indicated by the first information, or is not applicable to any area of ​​the cell, or is applicable to the entire area of ​​the cell.

[0237] For example, for MBS1, if the first information is not included in the MBS service configuration information corresponding to the MBS1 service, and the first information is included in the configuration information other than the MBS service configuration information corresponding to all MBS services, then one possibility is that the area applicable to the MBS service configuration information corresponding to MBS1 is the area indicated by the first information; another possibility is that the MBS service configuration information corresponding to MBS1 is not applicable to any area, and the UE will not receive MBS1 based on the MBS service configuration information corresponding to MBS1 in any area; yet another possibility is that the MBS service configuration information corresponding to MBS1 is applicable to all areas of the cell, and the UE will receive MBS1 based on the MBS service configuration information corresponding to MBS1 in all areas of the cell.

[0238] Assume the current communication system includes a cell, Cell1, which contains three areas: Area1, Area2, and Area3, and two services, MBS1 and MBS2. If the first information represents the area identifiers of Area1, Area2, and Area3, and the first information is not included in the MBS service configuration information corresponding to MBS1 and MBS2, but is included in the MBS configuration information other than the MBS service configuration information corresponding to MBS1 and MBS2, then the areas applicable to the MBS service configuration information corresponding to MBS1 and MBS2 are Area1, Area2, and Area3. The UE can then use MBS1... The corresponding MBS service configuration information can be used to receive MBS1 in Area 1, Area 2, and Area 3. MBS2 can be received in Area 1, Area 2, and Area 3 based on the MBS service configuration information corresponding to MBS2. Alternatively, it can mean that the MBS service configuration information corresponding to MBS1 and MBS2 is not applicable to any area, and the UE will not receive MBS1 and MBS2 in Area 1, Area 2, and Area 3. Or it can mean that the MBS service configuration information corresponding to MBS1 and MBS2 is applicable to any area in Cell 1, and the UE will receive MBS1 and MBS2 in all areas of Cell 1, Area 1, Area 2, and Area 3.

[0239] It should be noted that when MBS service is applicable to all areas of the cell that sends MBS service, the cell here can be the cell that sends MBS service, the cell that sends MBS configuration information, or the cell that sends system messages carrying scheduling information carrying MBS configuration information.

[0240] In one embodiment, for a single MBS service, if the first information is neither included in the MBS service configuration information corresponding to the MBS service, nor is the first information included in the configuration information other than the MBS service configuration information corresponding to all MBS services, the MBS service configuration information corresponding to the MBS service is applicable to all areas of the cell sending the MBS service, or is not applicable to any area of ​​the cell.

[0241] For example, for MBS1, if the first information is neither included in the MBS service configuration information corresponding to the MBS service, nor in the configuration information other than the MBS service configuration information corresponding to all MBS services, then one scenario is that the area applicable to the MBS service configuration information corresponding to MBS1 is the entire area of ​​the cell sending the MBS1 service. If the UE receives the MBS configuration information in Area 1 of Cell 1, then the MBS service configuration information corresponding to MBS1 applies to all areas in Cell 1, and the UE can receive MBS1 from all areas in Cell 1 based on the MBS service configuration information corresponding to MBS1. Another scenario is that the MBS service configuration information corresponding to MBS1 does not apply to any area, and the UE will not receive MBS1 based on the MBS service configuration information corresponding to MBS1 in any area. Another possibility is that the area to which the MBS service configuration information corresponding to MBS1 applies is the area where the MBS configuration information is received. If the UE receives the MBS service configuration information in Area 1, then the area to which the MBS service configuration information corresponding to MBS1 applies is Area 1, and the UE can receive MBS1 in Area 1 based on the MBS service configuration information corresponding to MBS1.

[0242] Assume the current communication system includes a cell, Cell1, which contains three areas: Area1, Area2, and Area3, and two services, MBS1 and MBS2. If the first information represents the area identifiers of Area1, Area2, and Area3, and the first information is not included in the MBS service configuration information corresponding to MBS1 and MBS2, but is included in the MBS configuration information other than the MBS service configuration information corresponding to MBS1 and MBS2, then the areas applicable to the MBS service configuration information corresponding to MBS1 and MBS2 are Area1, Area2, and Area3. The UE can receive MBS1 in Area1, Area2, and Area3 according to the MBS service configuration information corresponding to MBS1, and can receive MBS2 in Area1, Area2, and Area3 according to the MBS service configuration information corresponding to MBS2. This could also mean that the MBS service configuration information corresponding to MBS1 and MBS2 is not applicable to any area, and the UE will not receive MBS1 and MBS2 in Area1, Area2 and Area3.

[0243] It should be noted that when MBS service is applicable to all areas of the cell that sends MBS service, the cell here can be the cell that sends MBS service, the cell that sends MBS configuration information, or the cell that sends system messages carrying scheduling information carrying MBS configuration information.

[0244] In one embodiment, for a single MBS service, when the second information includes MBS service configuration information corresponding to the MBS service, the MBS service configuration information corresponding to the MBS service is the configuration information of the content indicated by the second information in the MBS service.

[0245] Specifically, when the second information indicates the content in the MBS service, for example, if the service identifier in the second information is included in the MBS service configuration information of the MBS service, the UE can use the corresponding MBS service configuration information to receive the content of the MBS service corresponding to the service identifier.

[0246] Suppose that the current communication system includes two services MBS1. MBS1 contains three contents: Content1 and Content2. The second information is represented by the content identifiers of Content1 and Content2. When the content identifier of Content1 is included in an MBS service configuration information, it means that the MBS service configuration information is the MBS service configuration information of Content1 in MBS1. When the content identifier of Content2 is included in an MBS service configuration information, it means that the MBS service configuration information is the MBS service configuration information of Content2 in MBS1.

[0247] In one embodiment, for a single MBS service, if the second information is not included in the MBS service configuration information corresponding to the MBS service, the MBS service configuration information corresponding to the MBS service is the configuration information of the MBS service.

[0248] For example, if the second information is not included in the MBS service configuration information corresponding to MBS1, it may mean that MBS1 has not been divided into different contents, and MBS1 is a complete service. The MBS service configuration information corresponding to MBS1 is the MBS service configuration information of MBS1. When the UE receives the MBS service configuration information of MBS1, it can receive MBS1 according to the MBS service configuration information corresponding to MBS1.

[0249] In this embodiment, the indication information does not include the first information, nor does it include the second information applicable to any MBS service. For example, if the MBS configuration information does not include either the first or the second information, one possibility is that the area to which the MBS configuration information applies is the area where the MBS configuration information is received. If the UE receives the MBS service configuration information in Area 1, then the area to which the MBS configuration information applies is Area 1. Another possibility is that the MBS configuration information does not apply to any area.

[0250] For example, if the UE does not receive the indication information, one possibility is that the area to which the MBS configuration information applies is the area where the MBS configuration information was received; another possibility is that the MBS configuration information does not apply to any area.

[0251] It should be noted that in some scenarios, the area where the MBS configuration information is received may be the only area of ​​the cell where the UE is located. For example, if the UE has only one area and does not receive the indication information, the area where the MBS configuration information is received is that unique area.
