Abstract
With the ever increasing demand for high speed and reliable communication systems, there is a need for the development of novel communication paradigms. Ultra-reliable low latency communications (uRLLC) and massive machine-type communications (mMTC) form the core use cases for next-generation wireless communication systems, including 5G and beyond. The numerous sensors in an Internet of things (IoT) setup with an access point, each with sporadic data to transmit, demand an uplink scheme that is specifically designed to accommodate small payloads. Many existing schemes propose different variations of codebook and power level designs for single-user and multi-user cases, with and without fading profiles. In this context, this thesis seeks to reduce the reliable number of channel uses required to keep the 95% detection success rate of the transmitted messages. The proposed uplink access framework builds on an existing scheme, called FASURA, which is tailored in the quasi-static Rayleigh fading channel with multi-user and multi-antenna system.
