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.

在现有的网络基础设施限制下，本论文探讨了在实际部署的多小区网络中最大化总速率性能的技术。我们提出了一种创新方法，将基站之间信息交换的需求大幅减少至几位比特，相较于传统方法需要数百位比特的交换方式。这种方法不仅解决了当前网络基础设施所带来的限制，而且在这些约束条件下展示出显著改进的性能。
