Description

Technical Field

[0001] The present application relates to the field of wireless communication systems, and more specifically to a wireless communication method and device for multicast / broadcast service (MBS), for example, particularly to an MBS system. Background Art

[0002] To achieve resource-efficient multicast / broadcast service transmission, 3GPP developed NR broadcast / multicast capabilities in Rel-17 according to work items (WIDs) to enable universal MBS services over 5GS. Applicable scenarios identified include public safety and mission-critical, V2X applications, IPTV, live video, software distribution over wireless transmission, and Internet of Things (IoT) applications. Rel-17 MBS has identified two transmission modes, where mode 1 (for multicast only) meets high QoS service requirements, while mode 2 (for broadcast only) focuses on low QoS service requirements. Given that Rel-17 MBS already provides basic functionality to support MBS services, the overall goal of Rel-18 should be to achieve more efficient MBS deployment based on Rel-17 MBS, such as improving resource efficiency and capacity.

[0003] In Rel-17, RAN specifies multicast only for UEs in RRC_CONNECTED state, which may not fully meet the needs of, for example, mission-critical services, especially in cells with a large number of UEs (according to TR 23.774). In addition, keeping UEs in RRC_CONNECTED state all the time is not energy-efficient. Therefore, it is very important to support multicast for UEs in RRC_INACTIVE state.

[0004] Therefore, a method and device for determining an applicable area for a point-to-multipoint (PTM) configuration of a user equipment (UE) receiving multicast in an RRC inactive state is required. Summary of the invention

[0005] The purpose of the present application is to propose a method and device for determining an applicable area for a point-to-multipoint (PTM) configuration of a user equipment (UE) receiving multicast in an RRC inactive state.

[0006] In a first aspect of the present application, a method performed by a user equipment (UE) for determining an applicable area for a point-to-multipoint (PTM) configuration for receiving multicast in an RRC inactive state includes: the UE receives an indication related to the area and / or PTM configuration.

[0007] In a second aspect of the present application, a user equipment (UE) includes a memory, a transceiver, and a processor coupled to the memory and the transceiver. The processor is configured to execute the above method.

[0008] In a third aspect of the present application, a non-transitory machine-readable storage medium stores instructions thereon, and when a computer executes the instructions, the instructions cause the computer to execute the above method.

[0009] In a fourth aspect of the present application, a chip includes a processor configured to call and run a computer program stored in a memory so that a device equipped with the chip executes the above method.

[0010] In a fifth aspect of the present application, a computer-readable storage medium stores a computer program, wherein the computer program enables a computer to execute the above method.

[0011] In a sixth aspect of the present application, a computer program product comprises a computer program, wherein the computer program enables a computer to execute the above method.

[0012] In a seventh aspect of the present application, a computer program is provided, wherein the computer program enables a computer to execute the above method. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The technical content, structural features, objectives and effects of the present application are described in detail below in conjunction with the accompanying drawings. Specifically, the terms in the embodiments of the present application are only used to describe the purpose of specific embodiments, and are not intended to limit the present application.

[0026] In the RANP#94 meeting, the following R18 work item (WID) was approved. This work item aims to further enhance the NR multicast / broadcast functionality based on Rel-17 MBS. The objectives of Rel-18 include: 1. Specify functionality to support UE reception of multicast in RRC_INACTIVE state [RAN2, RAN3]. Specify PTM configuration for UE reception of multicast in RRC_INACTIVE state [RAN2]. Study the impact of mobility and state transitions of UE receiving multicast in RRC_INACTIVE state [RAN2, RAN3]. 2. Specify Uu signaling enhancements to allow UE to receive unicast in RRC_CONNECTED state while receiving MBS broadcast from the same or different operators, including UE capability and related assistance information reporting [RAN2]. 3. Study and (if necessary) specify enhancements to improve resource efficiency of MBS reception in RAN sharing scenarios [RAN3]. Note: The above objectives are expected to be coordinated with SA2 in due course.

[0027] From the above, it can be seen that the PTM configuration obtained by the UE may be applicable to a specific area (i.e., a group of cells rather than a single cell). In other words, this specific area means that the PTM configuration of a multicast service in the area is the same. In this application, we refer to it as the PTM configuration M area of ​​the UE in the RRC_INACTIVE state.

[0028] In this application, we will discuss how to configure the M-zone for a UE in RRC_INACTIVE state.

In addition, in some embodiments, the processor 11 is configured to perform the following method.

[0031] Figure 2 The present invention is a flowchart showing a method for determining a point-to-multipoint (PTM) configuration applicable area for receiving multicast in an RRC inactive state, performed by a user equipment (UE) according to an embodiment of the present application. In some embodiments, a method 200 for determining an applicable area for a point-to-multipoint (PTM) configuration for receiving multicast in an RRC inactive state, performed by a UE, includes: step 202, receiving an indication related to an area and / or a PTM configuration by the UE.

[0032] In some embodiments, the region indicates that the PTM configuration acquired by the UE is applicable to the region; the region indicates that the PTM configuration of a multicast service in the region is the same; and / or the region indicates the PTM configuration M region of the UE in the RRC inactive state. In some embodiments, the indication is transmitted by the base station to the UE, and the indication indicates whether to use the notification area (RNA) based on the radio access network (RAN) as the M region. In some embodiments, RNA is used as the M region. In some embodiments, the indication indicates that RNA is not allowed to be used as the M region and the PTM configuration is used for the current serving cell. In some embodiments, the M region is controlled / configured by the network. In some embodiments, the network notifies the UE which cells belong to the M region. In some embodiments, the M region is controlled / configured by the RAN or the core network (CN). In some embodiments, if the M region is controlled / configured by the RAN, the indication is transmitted by the RAN / base station (BS) to the UE. In some embodiments, the indication is transmitted via a radio resource control (RRC) message, a system information block (SIB) or a multicast service control channel (MBS control channel, MCCH).

[0033] In some embodiments, the RRC message includes RRC release or RRC recovery. In some embodiments, if the M area is controlled by the CN, the indication is transmitted by the CN to the UE. In some embodiments, the indication is transmitted via non-access stratum (NAS) signaling. In some embodiments, the indication is transmitted from the CN to the base station and further transmitted from the base station to the UE via access stratum (AS) signaling. In some embodiments, AS signaling is transmitted via RRC messages, SIBs, or MCCH. In some embodiments, the RRC message includes RRC release or RRC recovery.

[0034] In some embodiments, the indication is used to inform the UE whether the M-area is enabled and / or whether the PTM configuration is used for the current cell. In some embodiments, explicit signaling is transmitted from the base station to the UE to inform the UE whether the M-area is enabled. In some embodiments, no configuration related to the M-area is transmitted from the base station to the UE, so as to implicitly let the UE know that the M-area is disabled and / or the PTM configuration is only valid in the current cell. In some embodiments, the indication is used to inform the UE whether the PTM configuration is allowed to apply to neighboring cells.

[0035] In some embodiments, the indication is transmitted by the network to the UE to inform the UE whether the PTM configuration is allowed to apply to the neighboring cell. In some embodiments, the indication includes the neighboring cell ID. In some embodiments, the indication is transmitted via an RRC message, a SIB, or an MCCH. In some embodiments, the RRC message includes an RRC release or an RRC recovery. In some embodiments, the indication is transmitted by the base station to the UE to inform the UE whether the M area is enabled and / or whether the PTM configuration is used for the current cell. In some embodiments, explicit signaling is transmitted from the base station to the UE to inform the UE whether the M area is enabled. In some embodiments, no configuration related to the M area is transmitted from the base station to the UE, so as to implicitly let the UE know that the M area is disabled and / or the PTM configuration is only valid in the current cell.

[0036] In some embodiments, whether RNA is used as an M-region relates to an RNA solution, the M-region indicated by the network relates to a configurable solution, and / or notifying the UE whether PTM configuration is allowed to apply to neighbor cells relates to a neighbor cell solution.

[0037] In some embodiments, whether the RNA solution, configurable solution and / or neighboring cell solution is used by the UE is configured by the network. In some embodiments, whether the RNA solution, configurable solution and / or neighboring cell solution is used by the UE is explicitly indicated by the network. In some embodiments, whether the RNA solution, configurable solution and / or neighboring cell solution is used by the UE is identified by the UE without explicit indication. In some embodiments, if the UE receives the RNA solution and the configurable solution at different times, one of the RNA solution, the configurable solution and the neighboring cell solution is valid. In some embodiments, the effectiveness of one of the RNA solution, the configurable solution and the neighboring cell solution is determined according to the priority of the RNA solution, the configurable solution and the neighboring cell solution, or the principle that the latest solution covers the old solution.

[0038] RNA as M region (RNA solution):

[0039] In the LTE system, the MME is responsible for allocating a Tracking Area (TA) to each registered UE. Figure 3 It is a schematic diagram of a notification area based on RAN according to an embodiment of the present application. Figure 3It is shown that in 5G, a new concept called RAN-based Notification Area (RNA) is introduced. When a UE moves out of the RNA cell list, it needs to report its location change, similar to the TAU concept in LTE, which is called RAN-based Notification Area Update (RNAU) (triggered by the serving ng-eNB or gNB). In this context, the mobility management in 5G has some improvements in Paging and RNAU procedures compared to LTE's mobility management to meet the needs of 5G use cases.

[0040] 5GC introduces a new TAU mechanism for UEs in the RRC inactive state, also known as RNAU, to track the location of the UE more accurately while reducing signaling overhead. Basically, the introduction of the RRC inactive state is to reduce Paging delay and achieve lightweight transition between this new state and the RRC connected state.

[0041] Figure 4 Flow chart of RNA solution according to an embodiment of the present application. RNA can be used as M region. Figure 4 Note that in some embodiments, the network (NW, such as a base station (BS)) may send an indication to the UE indicating whether the RNA is used as an M region. The indication may be carried by an RRC message (e.g., RRC release, RRC recovery, etc.) or SIB / MCCH. The base station may send an indication indicating that the RNA is not allowed to be used as an M region, and the PTM configuration is only used in the current serving cell.

[0042] The innovation of this solution is that RNA can be used as an M region. The base station can send an indication to the UE to indicate whether RNA is used as an M region. The indication can be carried by an RRC message (e.g., RRC release, RRC recovery, etc.) or SIB / MCCH.

[0043] Network (NW) indicates M area (configurable solution):

[0044] M-areas help energy saving and mobility, especially in congestion scenarios. Therefore, due to the dynamic changes in congestion conditions, the network may want to dynamically change the M-areas. The RAN is aware of the congestion conditions of the cell and can therefore control the M-areas. The core network (CN) is aware of the registration conditions and can therefore also play this role.

[0045] If the RAN can control the M area and send an indication to the UE notifying the M area, the indication may be transmitted via RRC signaling, such as RRC release, RRC recovery, etc. or SIB / MCCH.

[0046] If the CN can control the M area and send an indication to the UE notifying the M area, the CN can transmit the indication through NAS signaling, or the CN sends the indication to the base station, and the base station sends the indication to the UE through AS signaling, specifically through RRC signaling (such as RRC release, RRC recovery... or SIB / MCCH).

[0047] In this solution, the base station can also send an indication to notify whether the M area is enabled or the PTM configuration is only used in the current cell. The base station notifies the UE whether the M area is enabled through explicit signaling, or the base station does not transmit any M area-related configuration to the UE, thereby implicitly letting the UE know that the M area is disabled and the PTM configuration is only valid in the current cell.

[0048] The innovation of this solution is that the RAN can control the M area, or the CN can control the M area. In the case where the RAN controls the M area and sends an indication to the UE, the indication can be transmitted through RRC signaling, such as RRC release, RRC recovery, etc. or SIB / MCCH.

[0049] In the case where CN controls the M area and sends an indication to the UE, the CN can transmit the indication through NAS signaling, or the CN sends the indication to the base station, and the base station sends the indication to the UE through AS signaling, specifically through RRC signaling (such as RRC release, RRC recovery... or SIB / MCCH).

[0050] The base station may also send an indication to inform whether the M-zone is enabled or the PTM configuration is used only in the current cell.

[0051] The base station notifies the UE whether the M-area is enabled through explicit signaling, or the base station does not transmit any M-area-related configuration to the UE, thereby implicitly letting the UE know that the M-area is disabled and the PTM configuration is only valid in the current cell.

[0052] The UE is informed whether the PTM configuration is applicable to neighboring cells (neighboring cell solution).

[0053] Figure 5 It is a flowchart of a neighboring cell solution according to an embodiment of the present application. Figure 5 It is shown that in some embodiments, the UE may learn through the network (NW) whether the PTM configuration is applicable to the neighboring cell.

[0054] Figure 6 This is another flow chart of the neighboring cell solution according to an embodiment of the present application. Figure 5 In some embodiments, the indication may also include a neighboring cell ID. The indication may be transmitted via RRC signaling, such as RRC release, RRC recovery, etc. or SIB / MCCH.

[0055] For this solution, the base station can also send an indication to notify whether the M area is enabled or the PTM configuration is only used in the current cell. The base station notifies the UE whether the M area is enabled through explicit signaling, or the base station does not transmit any M area-related configuration to the UE, thereby implicitly letting the UE know that the M area is disabled and the PTM configuration is only valid in the current cell.

[0056] The innovation of this solution is that the UE can learn from the network whether the PTM configuration is applicable to the neighboring cell. The indication can be transmitted through RRC signaling, such as RRC release, RRC recovery... or SIB / MCCH. The base station can also send an indication to notify whether the M area is enabled or the PTM configuration is only used in the current cell. The base station notifies the UE whether the M area is enabled through explicit signaling, or the base station does not transmit any M area-related configuration to the UE, thereby implicitly letting the UE know that the M area is disabled and the PTM configuration is only valid in the current cell.

[0057] A combination of the above solutions:

[0058] The network (NW) can be configured to use which of the above two or more solutions. For example: Case 1: Introducing two solutions, such as "RNA solution" and "neighboring cell solution". Figure 7 A flow chart showing a solution combination according to an embodiment of the present application. Figure 8 A flow chart showing a solution combination according to an embodiment of the present application. Fig. 9 A flow chart showing a solution combination according to an embodiment of the present application.

[0059] Case 2: Introducing all the above solutions.

[0060] Fig.10 A flowchart is shown for introducing all solutions according to the embodiments of the present application.

[0061] Regarding how the UE identifies the solution to be used, two options can be considered. One is that the network can explicitly indicate the solution to be used. The other is that the UE can identify the solution to be used without explicit indication due to different ASN.1 formats. Regarding which configuration is valid when the UE receives multiple configurations at different times, two options can be considered.

[0062] One is to set priorities for these solutions. For example, if the "RNA solution" and the "neighboring cell solution" are introduced, the priority can be "RNA solution" first, "neighboring cell solution" second, or vice versa. If all the above solutions are introduced, the priority can be "RNA solution" first, "neighboring cell solution" second, "configurable solution" third, or other possibilities.

[0063] Alternatively, the latest configuration can overwrite the older configuration.

[0064] The innovation of this solution is that the network can configure which of the two or more solutions to use. Regarding how the UE identifies the solution to use, two options can be considered. One is that the network can explicitly indicate the solution to use. The other is that due to different ASN.1 formats, the UE can identify the solution to use without explicit indication.

[0065] Regarding which configuration is valid when the UE receives multiple configurations at different times, two options can be considered. One is to set priorities for these solutions. The other is that the latest configuration can overwrite the old configuration.
