IEEE DS: In-band coexistence and spectrum shared communication

Abstract: With the advent of Internet of Things, the growing need for rural broadband access, and pervasive coverage and connectivity interest via space-air-ground networks, managing dynamic requirement of spectrum and its scarcity has become a major research focus. To address the challenges associated with the increased demand of wireless spectrum, one approach is to improve spectrum utilization. While higher frequencies are suited for short-range point-to-point communication, regulatory agencies worldwide have also been focusing on the efficient reuse of the lower frequency bands, e.g., television (TV) and location services (NAVIC) bands, for non-broadcasting purposes. Besides, co-usage of common spectrum bands is being explored for higher spectral efficiency. In this talk we will discuss in-band coexistence in active broadcast bands, e.g., digital terrestrial television (DTT) and fixed satellite service (FSS) bands, also called TV gray spaces (TVGS) or TV black spaces (TVBS), as opposed to TV white spaces (TVWS). We will discuss one-sided in-band coexistence without necessarily maintaining the spatial and spectral `distance’, wherein the legacy users need to be protected while the coexisting entities aim to fulfil their required service quality by exploiting the unique transmission and signaling features of legacy transmissions and by dynamically adapting its transmission and interference mitigation abilities. We will then briefly discuss the possibilities of spectrum shared communication over a common band, wherein the coexisting parties participate for their respective communications by mutually adapting their transmission needs and interference management at the receiver, with as well as without the presence of a spectrum controller.
