DETAILED DESCRIPTION OF THE INVENTION

[0018] The following clearly describes the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present application fall within the scope of protection of the present application.

[0019] The terms "first," "second," etc. in the specification and claims of this application are intended to distinguish between similar objects and are not intended to describe a specified order or sequence. It is to be understood that terms used in this manner are interchangeable where appropriate, so that embodiments of this application may be performed in orders other than those illustrated or described herein, and that objects distinguished by "first" and "second" are generally of the same type and do not limit the number of objects; for example, a first object may be one or more. Furthermore, in the specification and claims, "and" indicates at least one of the connected objects, and the character " / " generally indicates an "or" relationship between the related objects.

[0020] It should be noted that the techniques described in the embodiments of the present application are not limited to Long Term Evolution (LTE) / LTE-Advanced (LTE-A) systems, but can also be applied to other wireless communication systems, such as Code Division Multiple Access (CDMA), Time Division Multiple Access (TDMA), Frequency Division Multiple Access (FDMA), Orthogonal Frequency Division Multiple Access (OFDMA), Single-carrier Frequency-Division Multiple Access (SC-FDMA), and other systems. The terms "system" and "network" in the embodiments of the present application are always used interchangeably, and the described techniques may be used in the above-mentioned systems and radio technologies as well as other systems and radio technologies. Although the following description describes a New Radio (NR) system for illustrative purposes and uses NR terminology in most of the following description, these techniques may be applied to applications other than NR system applications, such as 6th Generation (6G) communication systems.

[0021] To facilitate understanding of the embodiments of the present application, the following technical points will be introduced first.

[0022] 1. Overview of Multimedia Broadcast and Multicast Service (MBMS) or Multicast Broadcast Service (MBS): In a Long Term Evolution (LTE) system, MBMS services may be transmitted in the following two ways:

[0023] (1) MBMS / MBS transmission method 1: MBMS is transmitted via a physical multicast channel (PMCH) in a multimedia broadcast multicast service single frequency network (MBSFN) subframe.

[0024] Here, control information is transmitted via system information (e.g., System Information Block (SIB) 13) and a Multicast Control Channel (MCCH), and data is transmitted via a Multicast Traffic Channel (MTCH).

[0025] (2) MBMS / MBS transmission method 2: Transmission is performed over a Physical Downlink Shared Channel (PDSCH) channel that is scheduled by a Physical Downlink Control Channel (PDCCH).

[0026] Here, control information is transmitted via system information (e.g., SIB20) and a Single Cell Multicast Control Channel (SC-MCCH), and data is transmitted via a Single Cell Multicast Traffic Channel (SC-MTCH). Here, the SC-MCCH is transmitted via a PDSCH scheduled by a Single Cell (SC)-Radio Network Temporary Identity (RNTI) PDCCH, and the SC-MTCH is transmitted via a PDSCH scheduled by a Group Radio Network Temporary Identity (G-RNTI) PDCCH.

[0027] 2. Local MBS business overview: New Radio (NR) MBS supports various types and characteristics of MBS services, one of which is the Local MBS service. A Local MBS service is a groupcast or broadcast communication service that may be available only in a local service area (e.g., per cellular, Tracking Area (TA), or other geographic metric) and at specific times (e.g., during events, emergencies, or operational hours) for vehicle-to-everything (V2X), public safety, and other locally provided services.
