The field of wireless network technologies is moving towards more efficient and scalable solutions. Researchers are focusing on developing new architectures and protocols that can support the increasing demand for high-quality services. One of the key directions is the development of cell-free massive MIMO systems, which can provide uniform service quality to users. Another area of research is the application of non-orthogonal multiple access (NOMA) to grant-free transmissions, which can reduce the age of information in uplink status update systems. Type-based unsourced multiple access is also being explored as a promising approach for grant-free multiple access with correlated messages. Furthermore, there is a growing interest in developing unified network models for space-air-ground integrated networks, which can enable global range and seamless coverage. Noteworthy papers include: An Achievability Bound for Type-Based Unsourced Multiple Access, which derives an achievability bound for the performance of type-based unsourced multiple access systems. Type-Based Unsourced Multiple Access over Fading Channels with Cell-Free Massive MIMO, which extends the existing design of type-based unsourced multiple access to a more realistic environment with fading and multiple antennas. A Unified QoS-Aware Multiplexing Framework for Next Generation Immersive Communication with Legacy Wireless Applications, which establishes a unified QoS-aware framework that supports immersive communication and legacy wireless applications simultaneously.
