Enhancing Sum-Rate Performance in Constrained Multicell Networks: A Low-Information Exchange Approach
CoRR(2024)
摘要
Despite the extensive research on massive MIMO systems for 5G
telecommunications and beyond, the reality is that many deployed base stations
are equipped with a limited number of antennas rather than supporting massive
MIMO configurations. Furthermore, while the cell-less network concept, which
eliminates cell boundaries, is under investigation, practical deployments often
grapple with significantly limited backhaul connection capacities between base
stations. This letter explores techniques to maximize the sum-rate performance
within the constraints of these more realistically equipped multicell networks.
We propose an innovative approach that dramatically reduces the need for
information exchange between base stations to a mere few bits, in stark
contrast to conventional methods that require the exchange of hundreds of bits.
Our proposed method not only addresses the limitations imposed by current
network infrastructure but also showcases significantly improved performance
under these constrained conditions.
