dc.description.abstract | In this paper, we consider random access, in which multiple users randomly attempt to access to the base station. We show the limitation of conventional random access in highly dense LTE systems where collision occurs with high probability. We propose a compressive sensing scheme for random access in LTE systems with massive users. We address the proposed scheme is capable of much more successful connections with less collisions than the conventional random access scheme. We also address resource control by balancing resources in data transmission channels and random access channels. We derive the optimal balance of the two channels to maximize the normalized throughput in LTE systems. Numerical results show the analysis of the optimal balance is quite accurate. | - |
