In cellular massive Machine-Type Communications (MTC), a device can transmit\ndirectly to the base station (BS) or through an aggregator (intermediate node).\nWhile direct device-BS communication has recently been in the focus of 5G/3GPP\nresearch and standardization efforts, the use of aggregators remains a less\nexplored topic. In this paper we analyze the deployment scenarios in which\naggregators can perform cellular access on behalf of multiple MTC devices. We\nstudy the effect of packet bundling at the aggregator, which alleviates\noverhead and resource waste when sending small packets. The aggregators give\nrise to a tradeoff between access congestion and resource starvation and we\nshow that packet bundling can minimize resource starvation, especially for\nsmaller numbers of aggregators. Under the limitations of the considered model,\nwe investigate the optimal settings of the network parameters, in terms of\nnumber of aggregators and packet-bundle size. Our results show that, in\ngeneral, data aggregation can benefit the uplink massive MTC in LTE, by\nreducing the signalling overhead.\n
