Preamble retransmission assisted control-based mMTC dynamic random access
To address the issue of severe network congestion in the scenario of massive machine-type communications (mMTC), where machine-type communication devices (MTCD) employing traditional random access schemes often encountered challenges leading to a large number of MTCD failing to access the network su...

| description | To address the issue of severe network congestion in the scenario of massive machine-type communications (mMTC), where machine-type communication devices (MTCD) employing traditional random access schemes often encountered challenges leading to a large number of MTCD failing to access the network successfully, a novel approach called preamble retransmission-based dynamic access class barring (PRT-ACB) was proposed.By utilizing the number of MTCD preamble retransmissions, the MTCD attempting to initiate access in each random access opportunity (RAO) were categorized into different sets of high and low priority.In conjunction with an estimation model for the number of payloads in each RAO, high and low-priority limiting factors and available preamble pools were dynamically adjusted based on the access load in each RAO.This allowed more MTCD to successfully access the network before reaching the maximum number of preamble transfers.Simulation results have demonstrated that the proposed scheme effectively enhances the MTCD successful access rate and reduces the time delay required for MTCD to access the network.The proposed scheme can serve as a solution to alleviate the congestion caused by a massive influx of communication devices attempting simultaneous network access. |
