Machine to machine communication is an important scenario in a 6G communication network. Random multiple access has recently been revisited and considered a key technology for machine to machine communication scenarios due to many advantages such as without coordination setup time. It is a regret that packet collision probability will be extremely higher for random multiple access when massive devices randomly accessing base station. Decentralized power control is an efficient scheme in random multiple access systems which can support intraslot successive interference cancellation to recover multiple collided packets at receivers. However, existing studies of decentralized power control for random multiple access are with the assumption that blocklength of transmitted packets is infinite, which neglects that machine to machine communication is characterized by finite blocklength transmission (i.e., short packet) in 6G. This paper focuses decentralized power control with short packet transmission in random multiple access systems. First, the closed-form expression of signal to interference plus noise ratio (SINR) threshold for short packets is derived. Then, decentralized transmission power profile is defined based on derived SINR threshold of short packets, which can support intraslot successive interference cancellation deciding at receivers for an ALOHA-type random multiple access system. Further, we propose derivation method to maximize system throughput, which can reduce optimization cost. Theoretical findings in this paper can provide valuable benchmark for short packet transmission with decentralized power control in random multiple access systems.

“…Long Term Evolution (LTE) network [1,2] which is a standard for 4G wireless broadband technology based on original 3G technologies is one of the best choices as a communication system to deploy MTC devices due to its high data rate, large coverage area, increased scalable network capacity, reduced latency, and backward compatibility with existing GSM and UMTS technology. Some challenges face the use of LTE networks for MTC communication [1][2][3][4][5][6][7][8]. One of the challenges is high overhead compared with the transmitted data.…”

Machine Type Communication (MTC) over the cellular network plays an important role in many smart applications. Long Term Evolutionary (LTE) network is considered the best cellular network for deploying the MTC devices in remote areas because of its high data rate and wide coverage area. The massive access of the MTC devices over LTE network results in poor network performance due to the high collision rate, high retransmission rate, high overhead, high delay, low throughput, and high power wastage. This paper proposes a new access technique to increase the access performance for MTC over LTE network. It is based on the clustering and grouping approach and resources sharing using the capillary network without using cluster head/helper node. In the proposed technique, MTC devices are divided into WLAN groups based on the geographical distance. In each WLAN, an MTC device can ask for uplink resources for data transmission from eNB for individual use or a group use. The MTC device shares the allocated resources with other devices inside its WLAN after finishing its data transmission using Distributed List Hub Polling (DLHPL) MAC protocol. The other devices inside the same WLAN can contend locally on these free resources without querying the eNB. The devices send data frames over LTE using these shared uplink resources without the need to relay it through a head node. The experimental results show that the proposed access technique gives lower collision rate, higher access probability, higher transmission opportunity, higher resources utilization, lower overhead, higher throughput, and lower delay compared with other recent techniques.
