Abstract: Methods and apparatuses are provided in a wireless communication system. A service data unit (SDU) is received from an upper layer. A protocol data unit (PDU) including a header for the SDU is generated based on an expiry of a timer for the SDU or an indication obtained from the upper layer. The PDU including the header is delivered to a lower layer. The PDU includes only the header and does not include a payload.

Abstract: A communication method and a system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT) are provided. The disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. Embodiments allow sending interest indication, by a user equipment (UE), to a 5G network, to indicate whether the UE is interested in receiving multicast and broadcast services (MBS) and/or MBS that are being currently received by the UE. Embodiments provide a mechanism to send interest indication.
