Popis: LTE Release 13 has introduced coverage enhancement (CE) mode "CE Mode B" to support MTC deployments that require medium-to-large CE, compared to the baseline LTE coverage for voice communications. In this paper, we describe the operation of CE Mode B for the supported physical data and control channels, and study the dimensioning of this mode for each of these channels. We provide link-level simulation results for CE Mode B, which illustrate the possibility of MTC operation at a coupling loss up to 160 dB. Further, we study the achievable uplink capacity in terms of the blocking probability of new scheduling requests. Finally for a few representative scenarios, we show that the existing LTE configurations can provide sufficient uplink capacity.
