Description

Information sending and receiving method and device Technical Field

[0001] The present application relates to the field of communications. Background Art

[0002] According to the 5G specification, the Multicast and Broadcast Services (MBS) feature of terrestrial network (TN) systems can also be used in NR non-terrestrial network (NTN) systems. Leveraging the wider coverage area of ​​NTN systems, MBS provides significant added value for NR NTN systems.

[0003] In the NR NTN system, the coverage area of ​​a cell is sometimes large enough to cover two or more countries. Figure 1 is a schematic diagram of the cell coverage area of ​​the NR NTN system. As shown in Figure 1, the cell of the NR NTN system covers two countries, Country A and Country B.

[0004] Due to legal, billing, and information content considerations, MBS services may only be intended for one of two countries. This means the MBS intended service area (ISA) only encompasses a portion of the NTN cell coverage. Therefore, system information enhancements are required to indicate the service area for multicast or broadcast services.

[0005] The 3GPP Release 19 (R19) work item description (WID) states that a multicast or broadcast service may not be expected to provide the entire coverage area of ​​an NTN cell. The R19 standardization work needs to indicate the intended service area (Intended Service Area) of the service through a specified SIB to cope with the situation where the satellite coverage area is too large.

[0006] It should be noted that the above description of the technical background is merely for the purpose of providing a clear and complete description of the technical solutions of this application and facilitating understanding by those skilled in the art. Simply because these solutions are described in the background technology section of this application, it should not be assumed that the above technical solutions are well known to those skilled in the art.

[0007] Summary of the Invention

[0008] According to current 3GPP specifications, a terminal device obtains MBS broadcast configuration information (MBSBroadcastConfiguration) by receiving the MCCH configuration provided in SIB20. It then obtains the MTCH configuration from the MBSBroadcastConfiguration, obtains the G-RNTIs from the mbs-SessionInfoList in the MBSBroadcastConfiguration, and demodulates the MTCH content carried on the PDSCH based on the G-RNTI. SIB20 is obtained using the SI-SchedulingInfo indicated in SIB1.

[0009] SI-SchedulingInfo includes systemInformationAreaID, which is used to indicate the area identifier to which the cell belongs. This identifier is unique in a PLMN (Public Land Mobile Network) or SNPN (Standalone Non-Public Network). Any SIB that is configured with areaScope in the system information scheduling information (SI-SchedulingInfo) is considered to belong to this systemInformationAreaID. If areaScope-r17 is included in the SIB-TypeInfo-v1700 related to SIB20, SIB20 is considered to be applicable to the area specified by systemInformationAreaID. In other words, the area attributes to which the system information currently belongs cannot be configured separately according to the SIB. At the same time, the minimum range indicated by systemInformationAreaID is the PLMN or SNPN level, and cannot indicate a range smaller than the PLMN or SNPN.

[0010] SIB20 includes MCCH configuration information and the common frequency resources for receiving MCCH and MTCH, but does not restrict the expected service area. MBS broadcast configuration information includes the MBS Session List (MBS-SessionInfo-r17), which indicates each MBS Session and contains MTCH scheduling information and the corresponding G-RNTI (group radio network temporary identifier). Like SIB20, it also does not restrict the expected service area.

[0011] The inventors found that when the coverage of the NTN cell exceeds the expected service area of ​​the service, according to the current specifications, the network cannot instruct the terminal device based on the expected service area of ​​the service, or prevent the terminal device outside the expected service area from monitoring / detecting / using the service.

[0012] In addition, according to the requirements of R19WID, for cases where the satellite coverage area is large, SIB needs to be specified to indicate the expected service area.

[0013] In addition, in the NTN system, broadcast or multicast services whose expected service area is different from the cell coverage area may not be limited to MBS services. Therefore, the SIBs that need to be enhanced to indicate the expected service area may not be limited to SIBs related to MBS services.

[0014] Although broadcast or multicast services can be used in both NR TN and NR NTN cells, the situation where the cell coverage exceeds the expected service area of ​​the broadcast or multicast service is more common in NTN cells. Therefore, NR TN cells may not expect to be affected by the relevant improvements. For example, improvements to the SIB to indicate the expected service area of ​​the service should not affect the NR TN cells.

[0015] In addition, the WID for NR NTN in R19 does not clearly indicate the granularity of the intended service area. For a broadcast or multicast service that is not intended to be provided to the entire cell coverage, the designated service area in which it is allowed or prohibited may be certain designated countries or certain designated planned areas.

[0016] In addition, in addition to system information, service configuration information can also be used to indicate the expected service area of ​​the service. For example, for an MBS service, the expected service area of ​​the MBS can be indicated in MBSBroadcastConfiguration-r17.

[0017] In order to solve one or more of the above problems, embodiments of the present application provide a method and apparatus for sending and receiving information.

[0057] The following describes various implementations of the present application in conjunction with the accompanying drawings. These implementations are merely illustrative and are not intended to limit the present application.

[0058] Embodiments of the first aspect

[0059] An embodiment of the present application provides a method for sending and receiving information, which is applied to a terminal device, such as the terminal device 102 in Figure 2.

[0060] FIG3 is a schematic diagram of a method for sending and receiving information according to an embodiment of the present application. As shown in FIG3 , the method includes:

[0061] 301: The terminal device receives first information from the network device;

[0062] The first information is at least used to indicate service area related information of a service. The first information is indicated by SIB related to the service and / or configuration information related to the service. The service is a service with a designated service area.

[0063] In operation 301, the terminal device receives first information from the network device; the first information is used to indicate at least service area related information of a service, the first information is indicated by SIB related to the service and / or configuration information related to the service, and the service is a service with a specified service area.

[0064] Alternatively, operation 301 may also be described as: the terminal device receives service area related information of a service from the network device, the service area related information of the service is indicated by the SIB related to the service and / or the configuration information related to the service, and the service is a service with a specified service area.

[0065] In some embodiments, the service is a broadcast or multicast service;

[0066] In some embodiments, a service with a designated service area means that a broadcast or multicast service may be a customized service within a specific range (service area) and is only allowed or valid within that specific range. In a cell with a very large coverage area, the service may only be applicable to a portion of the cell rather than the entire cell coverage area. Therefore, the network needs to notify the terminal device of information related to the service area of ​​the service.

[0067] In some embodiments, the service area of ​​a service refers to a designated service area of ​​the service, which may also be referred to as an expected service area of ​​the service, a predetermined service area of ​​the service, or an intended service area of ​​the service.

[0068] In some embodiments, the area not served by the service refers to the area outside the designated service area of ​​the service, which can also be called the non-service area of ​​the service, the non-expected service area of ​​the service, the non-scheduled service area of ​​the service, or the area not expected to be served by the service.

[0069] In some embodiments, the broadcast or multicast service is not limited to MBS (Multicast and Broadcast Services) whose expected service area does not include the entire cell coverage area, but may also be a broadcast service or multicast service that other networks expect to provide to terminal users in a predetermined area.

[0070] In some embodiments, the service area related information may include the expected service area of ​​the service, that is, the designated service area information where the network allows or expects the terminal device to use the service, and may also include the non-expected service area of ​​the service, that is, the area information where the network prohibits or does not expect the terminal device to use the service, or may only include indication information to indicate that the service is a service with a specific area rather than the entire cell as its service scope.

[0071] In some embodiments, the service area related information of a service may be indicated by a system information block (SIB) related to the service, and / or may be indicated by a configuration message related to the service.

[0072] In some embodiments, the service is not limited to the MBS service. Therefore, the service-related SIBs may include not only SIB1 and SIB20 related to the MBS service, but also SIBs related to other services; the service-related configurations may include not only MBS-related configurations, but also configurations related to other services.

[0073] The following describes in detail how to indicate the service area information of a service.

[0074] In some embodiments, service area related information of the service is indicated in a SIB related to the service, and the SIB related to the service includes scheduling information of the SIB related to the service and / or an SIB information element (IE) related to the service.

[0075] In some embodiments, the service area related information of the service is indicated in the scheduling information of the SIB related to the service, for example, the service area related information of the service is indicated in the scheduling information of the SIB of the service (for convenience of description, referred to as "method one"). Method one is described in detail below.

[0076] In some embodiments, the scheduling information (Scheduling Information) of the SIB of the service is included in the system information scheduling information (SI Scheduling Information) related to the SIB in the SIB1 message.

[0077] For example, in SI-SchedulingInfo or SI-SchedulingInfo-v1700;

[0078] For another example, SchedulingInfo in schedulingInfoList of SI-SchedulingInfo;

[0079] For another example, SchedulingInfo2-r17 in schedulingInfoList2-r17 of SI-SchedulingInfo-v1700.

[0080] In this way, the service area related information of the service is indicated in the scheduling information of the system information, thereby indicating the service area of ​​all system information related services scheduled in the system scheduling information, avoiding repeated indication of services with the same service area attributes, and saving the overhead of the signaling payload.

[0081] In some embodiments, the service area related information of the service is indicated in the system information block type information of the SIB related to the service, and the system information block type information is included in the SIB mapping information structure of the scheduling information of the SIB related to the service.

[0082] For example, the service area related information of the service is indicated in the system information block type information (SIB Type Information) of the SIB of the service. The system information block type information is included in the SIB mapping information (SI Mapping Information) structure in the scheduling information under the system information scheduling information (SI Scheduling Information) of the SIB of SIB1.

[0083] For example:

[0084] SIB-TypeInfo under sib-MappingInfo of SchedulingInfo;

[0085] SIB-TypeInfo-v1700 under sib-MappingInfo-r17 of SchedulingInfo2-r17.

[0086] In this way, the service area related information of the service is indicated in the configuration of the system information block type, and the service area can be indicated for different SIB-related services respectively. For different SIBs in the same system information scheduling configuration, the related services can be used for the entire cell or have different service areas, which increases flexibility.

[0087] The above specifically describes the method of indicating the service area related information of a service in the scheduling information of the SIB of the service, namely Method 1. Because the service area related information of the service is included in the configuration of the system information scheduling, the terminal device can decide whether to further detect the corresponding SIB content based on this configuration, avoiding unnecessary detection and decoding, and saving power consumption of the terminal device.

[0088] In some embodiments, the service area related information of the service is indicated in a SIB information element related to the service (for the convenience of description, referred to as "method 2").

[0089] For example, for an MBS service, information related to the service area of ​​the MBS service is indicated in SIB20-r17.

[0090] In this way, indicating the service area information of a specific service in the SIB related to the service can avoid affecting other services applicable to the entire cell. Only when the service may be partially applicable to the coverage area of ​​the cell, it may be necessary to indicate the service area of ​​the service. By applying method 2, the terminal user decides whether to further read or detect the information of the service related to the SIB based on the service area information of the service indicated in the SIB.

[0091] In some embodiments, within an NTN cell, for services with designated service areas, i.e., services intended to be provided only to terminal devices within, or available or valid only within, a portion of the cell's coverage area, the service area-related information for these services may be indicated via NTN-related signaling. TN cells are not affected by this NTN-related signaling improvement (referred to as "Method 3" for ease of description). Method 3 is described in detail below.

[0092] In some embodiments, in an NTN cell, the service area related information of the service is indicated in the scheduling information of SIB19.

[0093] For example, the indicated location includes at least one of the following:

[0094] Used in SchedulingInfo2-r17 of SIB19;

[0095] Used in SIB-TypeInfo-v1700 of SIB19.

[0096] In some embodiments, in an NTN cell, the service area related information or a service area related information list of the service is indicated in an information element of SIB19.

[0097] For example, the indicated location includes at least one of the following:

[0098] In SIB19-r17;

[0099] In ntn-Config-r17 of SIB19-r17.

[0100] In some embodiments, in an NTN cell, the service area related information of the service indicated includes at least one of the following:

[0101] Information related to the service area of ​​the business or a list of information related to the service area;

[0102] Service information or a list of service information with a specified service area; for example, the service information may include service ID, service name, service-related SIB, etc.;

[0103] A mapping relationship between the service area related information of the service and the service information with the designated service area.

[0104] In some embodiments, the mapping relationship between the service area related information of the service and the service information with the specified service area includes at least one of the following:

[0105] The mapping of the service area related information of the service to the services or service information or service information list within the service area; for example, the configuration of a specified service area in an NTN cell (such as ntn-areaScope), which includes not only the service area but also the services (list) within the service area;

[0106] The mapping of the service information to the service area related information or service area related information list of the service; for example, the configuration of a service with a specified service area in an NTN cell (such as ntn-areaService), which includes, in addition to the service identifier, the service area related information (list) of the service.

[0107] In this way, the service area information of the service is indicated through NTN-related signaling, which can avoid the impact on the TN system: no new signaling content or message content will be added to the TN system, and the terminal users in the TN system do not need to support or judge the relevant features.

[0108] In some embodiments, the service area related information of the service is indicated in the configuration information related to the service (for the convenience of description, referred to as "method four"). Method four is described in detail below.

[0109] In some embodiments, the service is an MBS service, and the related configuration information is an MBS broadcast configuration.

[0110] For example, as option 1, the service area related information of all sessions of the MBS service is indicated in the MBS broadcast configuration; for example, the service area related information is included in at least one of the following:

[0111] MBSBroadcastConfiguration-r17;

[0112] In criticalExtensions under MBSBroadcastConfiguration-r17;

[0113] Under MBSBroadcastConfiguration-r17-Ies in criticalExtensions under MBSBroadcastConfiguration-r17.

[0114] For another example, as option 2, the service area related information is indicated separately for different sessions of the MBS service in the MBS broadcast configuration; in this way, different MBS sessions can be configured with different service area related information, for example, the service area related information is included in each MBS-SessionInfo-r17 of the MBS-SessionInfoList-r17 under MBSBroadcastConfiguration-r17-IEs.

[0115] In some embodiments, the SIB associated with the service indicates that the service is a service with a specified service area, and the configuration information associated with the service indicates the (un)expected service area of ​​the service, i.e., the unexpected service area and / or the expected service area.

[0116] That is to say, method 4 can be combined with method 1, method 2 and method 3, that is, in the SIB, only whether the service serves the specified area rather than the coverage of the entire cell is indicated, and the specific non-expected service area and / or expected service area of ​​the service is indicated in the configuration related to the service.

[0117] In this way, the service area information of a service is indicated in the service-related configuration information. A common service area can be configured for all sub-services or service sessions included in the service, or different service areas can be configured for different sub-services or sessions of the service. For example, for MBS services, different sessions may have different expected service areas. Option 2 of Method 4 allows different service areas to be configured for different MBS sessions, increasing flexibility.

[0118] In some embodiments, for services whose service area is not the entire cell, the network indicates to the terminal device information related to the service area of ​​the service to prevent the terminal user from attempting to resolve or use the service in unnecessary areas or prohibited areas. The service area related information of the service can be either the expected service area of ​​the service, such as the area where the service is expected to provide service or the area where the service is allowed to provide service; or it can be the unintended service area of ​​the service, such as the area where the service is not expected to provide service or the area where the service is prohibited.

[0119] For the unexpected service area and / or expected service area of ​​the business, there are many possible ways to divide it according to different needs. For example, the service area can be divided by using existing area definitions, such as country codes, tracking area indications, etc.; new area identifiers can also be defined or allocated for division.

[0120] In some embodiments, the service area related information of the service includes at least one of the following:

[0121] an indication that the business is a business with a designated service area;

[0122] The service area (expected service area) of the business;

[0123] The non-service area (non-expected service area) of the business.

[0124] In some embodiments, the service area (expected service area) of the service and / or the non-service area (non-expected service area) of the service are indicated by at least one of the following methods:

[0125] The area covered by the specified beam or beam list;

[0126] Areas belonging to a specified PLMN or PLMN list;

[0127] Areas belonging to a designated TAI (Tracking Area Identity) or TAI list;

[0128] an area belonging to a specified area identifier or a list of area identifiers, where the specified area identifier is an identifier assigned by the network to a planned ground area;

[0129] Enhance existing system information definitions.

[0130] In some embodiments, the area covered by a specified beam or list of beams may be indicated as follows:

[0131] For example, based on the non-expected service area and / or expected service area of ​​the service, the network indicates to the terminal device a beam or a beam list covering the non-expected service area and / or expected service area of ​​the service;

[0132] For example, the terminal device obtains the beam to which it belongs based on its physical location or beam measurement method. When the beam to which the terminal device belongs matches the beam or beam list of the expected service area of ​​the service indicated by the network, the terminal device attempts to parse the information related to the service and use the service. Otherwise, the terminal device does not decode or detect any information about the service. When the beam to which the terminal device belongs matches the beam or beam list of the service not expected to be served by the service indicated by the network, the terminal device does not decode or detect any information about the service. Otherwise, the terminal device attempts to parse the information related to the service and use the service.

[0133] For example, the network can also adjust the coverage of the beam or beam list by dynamically adjusting the beam pattern, and use the beam or beam list that only covers the service area of ​​the service for the transmission related to the service, and avoid using the beam or beam list whose coverage includes non-service areas.

[0134] In some embodiments, the indication of an area belonging to a specified PLMN or PLMN list is as follows:

[0135] For example, when the unintended service area and / or the intended service area of ​​a service is divided or restricted by country, the network may indicate the unintended service area and / or the intended service area of ​​the service by indicating the PLMN or PLMN list of the unintended service area and / or the intended service area of ​​the service to the terminal device;

[0136] For example, when the PLMN to which the terminal device's current location belongs matches the PLMN or PLMN list of the expected service area of ​​the service indicated by the network, the terminal device attempts to parse the service-related information and use the service, otherwise the terminal device does not decode or detect any information about the service. When the PLMN to which the terminal device's current location belongs matches the PLMN or PLMN list of the non-expected service area of ​​the service indicated by the network, the terminal device does not decode or detect any information about the service, otherwise the terminal device attempts to parse the service-related information and use the service.

[0137] In some embodiments, the indication of an area belonging to a specified TAI or TAI list is as follows:

[0138] For example, the TAI is composed of the PLMN ID and the TAC. When the unintended service area and / or the intended service area of ​​the service can be distinguished by the TAI, the network can indicate the unintended service area and / or the intended service area of ​​the service to the terminal device by indicating the TAI or TAI list of the unintended service area and / or the intended service area of ​​the service.

[0139] For example, the NTN network can determine the association between the TAI and the non-expected service area and / or the expected service area of ​​the service based on the existing TN network's division of TAIs, or the mapping of the NTN network's lower TAIs and ground locations, and further determine the TAI or TAI list of the non-expected service area and / or the expected service area of ​​the service;

[0140] For example, when the TAI of the current location of the terminal device matches the TAI or TAI list of the expected service area of ​​the service indicated by the network, the terminal device attempts to parse the service-related information and use the service. Otherwise, the terminal device does not decode or detect any information about the service. When the TAI of the current location of the terminal device matches the TAI or TAI list of the non-expected service area of ​​the service indicated by the network, the terminal user does not decode or detect any information about the service. Otherwise, the terminal device attempts to parse the service-related information and use the service.

[0141] In some embodiments, the indication method of the area belonging to a specified area identifier or area identifier list is as follows:

[0142] For example, the service area of ​​a service may not be divided by existing area-related identifiers. Depending on different service requirements, the unintended service area and / or intended service area of ​​the service may be a specific area or areas. The network introduces new area identifiers for such specific areas.

[0143] For example, the network can indicate the mapping relationship between the area identifier and the specific area to the terminal device within the coverage area, or assign the area identifier to the terminal device according to its location. For users who are not in a specific area, the network may not configure the area identifier for them.

[0144] For example, the terminal device determines the area identifier of the current location based on the current location or network indication; if the location of the terminal device does not belong to a certain specific area, the terminal device may not be configured with a specific area identifier;

[0145] For example, the network indicates to the terminal device the area identifier or area identifier list of the non-expected service area and / or the expected service area of ​​the service to indicate the non-expected service area and / or the expected service area of ​​the service.

[0146] For example, when the terminal device has an area identifier and the identifier matches the expected service area identifier or area identifier list of the service indicated by the network, the terminal device attempts to parse the service-related information and use the service. Otherwise, the terminal device does not decode or detect any information about the service. When the terminal device does not have an area identifier or the identifier matches the identifier or area identifier list of the non-expected service area of ​​the service indicated by the network, the terminal device does not decode or detect any information about the service. Otherwise, the terminal device attempts to parse the service-related information and use the service.

[0147] In some embodiments, the indication method of enhancing the existing system information definition is as follows:

[0148] For example, the enhanced existing system information definition includes at least one of the following:

[0149] The system information area identifier in the existing system information scheduling information indicates the area identifier to which the system information and services related to the system information are applicable. For example, SI-SchedulingInfo includes systemInformationAreaID, which is used to indicate the area identifier to which the system information is applicable. The area may include the coverage of the entire cell or only the coverage of the cell.

[0150] The type information of each SIB in the existing system information scheduling information indicates that the SIB and the services related to the SIB are services with a specified service area; for example, areaScope in SIB-TypeInfo is used to indicate that the SIB and the services related to the SIB are services with a specified service area;

[0151] The sub-area identifier of the system information area identifier is added to the type information of each SIB in the existing system information scheduling information. The sub-area identifier is used to indicate the service area of ​​the SIB and the services related to the SIB; for example, SIB-TypeInfo, the sub-area identifier of the system information area identifier of the SIB is added, such as systemInformationSubAreaID or SIBAreaID, to indicate the service area of ​​the SIB and the services related to the SIB.

[0152] In the embodiments of the present application, the method for indicating the non-expected service area and / or the expected service area of ​​a service can be flexibly determined based on the current service requirements, thereby avoiding unnecessary signaling interactions and signaling payload overhead caused by unnecessary area refinement.

[0153] In this way, through the above various indication methods, it is clarified how the network indicates the service area of ​​a service to the terminal device when the expected service area of ​​the service is different from the entire cell coverage area. When the identifiers that can represent the area defined in the existing network cannot meet the needs of services with designated service areas, new area identifiers can be introduced to indicate the non-expected service area and / or the expected service area of ​​the service. The network can also prevent service-related information from being transmitted outside the expected service area of ​​the service by dynamically adjusting the beam model.

[0154] As can be seen from the above embodiment, the network indicates to the terminal device information related to the service area of ​​the service, meeting the enhanced requirements for SIB when the cell coverage exceeds the expected service area of ​​the broadcast or multicast service, and taking into account other services other than MBS services that require the definition of the expected service area, providing a solution to avoid the impact on the TN system, and providing a feasible indication method for the content of specific service area information. The terminal device adjusts the subsequent processing related to the service according to the network indication, avoiding unnecessary or non-compliant service detection and analysis, while saving power consumption of the terminal device.
