The present 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. Apparatuses and methods for transmitting or receiving a synchronization signals and physical broadcast channel (SS/PBCH) block in a wireless communication system. A method of operating a user equipment (UE) includes receiving a SS/PBCH block, decoding a content of a PBCH in the SS/PBCH block, and determining whether the wireless communication system operates with shared spectrum channel access based on the content of the PBCH. The method further includes determining the content of the PBCH in a first manner based on determining that the wireless communication system operates with shared spectrum channel access or determining the content of the PBCH in a second manner based on determining that the wireless communication system operates without shared spectrum channel access.

Abstract: A base station can implement a method for managing transmission of multicast and/or broadcast services (MBS) using semi-persistent scheduling (SPS). The method includes: transmitting (1702), to a user equipment (UE), a configuration for receiving MBS data on SPS radio resources; providing (1704), to the UE, an indication to activate receiving the MBS data in accordance with the configuration; and transmitting (1706), to the UE, the MBS data in accordance with the configuration.

Abstract: Methods, systems, and devices for wireless communication are described. Generally, the described techniques provide for efficiently allocating resources for multicast feedback from one or more user equipment (UEs) and efficiently retransmitting information in transport blocks to the one or more UEs. If a UE fails to decode one or more transport blocks of a set of transport blocks from a base station, the UE may report feedback, such as a negative acknowledgment (NACK), to the base station. The base station may receive the feedback from the UE and potentially from other UEs that failed to decode one or more transport blocks of the set of transport blocks, and the base station may multicast one or more outer-coded transport blocks to the UEs. Each of the outer-coded transport blocks may include a different combination (for example, a linear combination) of transport blocks of the set of transport blocks.
