This paper addresses self-optimization of the random access channel (RACH) in the Third-Generation Partnership Project (3GPP) Long-Term Evolution (LTE). Ensuring satisfactory random access (RA) performance in terms of access delay (AD) is crucial for reducing the delays associated with initial access and handovers. The feasibility of self-optimization is investigated by means of simulations, where...
The uplink spectral-efficiency of space-division multiple-access (SDMA) cellular systems is studied, when distributed base-station (BS) detection and distributed BS cooperation are employed. In contrast to the related works in literature, which mainly consider the linear and hexagonal Wyner models (or their extensions) with a constant factor for intercell interference (ICI), we address the impacts...
