Abstract
Multi-connectivity, connections among multiple small cells (SCs) simultaneous, is used to be a promising solution to achieve high reliability in indoor millimeter-wave (mmWave) networks. This work further improves the multi-connectivity estimation under scenarios with strictly-limited training steps. To quickly estimate multiple links connected to different SCs, we propose a novel scattering multi-beam codebook (SMBC). Then, we develop a scattering multi-connectivity estimation (SMCE) measuring effective possible links instead of all possible links. From our simulation results, our method can complete multi-connectivity in only 20% of the training steps in the uplink exhaustive measurement (UEM).
