Taking advantage of the broadcast nature of radio frequency (RF) wave propagation, simultaneous wireless information and power transfer (SWIPT) has recently gained significant research attention since it can prolong the battery-life of energy-constrained and low-power-supported mobile devices. In addition, due to the potential benefits of favorable propagation and channel hardening, cell-free (CF) massive multi-input multi-output (m-MIMO) can significantly enhance the QoS performance of SWIPT in terms of the achievable data rate and energy efficiency. On the other hand, finite blocklength coding (FBC) has been proposed to guarantee stringent QoS requirements while reducing the access latency using short-packet communications. However, how to efficiently integrate these new techniques using FBC based statistical delay-bounded QoS theory has imposed many new challenges not encountered before. To overcome these difficulties, in this paper we propose and develop statistical delay and error-rate bounded QoS provisioning schemes over SWIPT-enabled CF m-MIMO 6G wireless networks in the finite blocklength regime. In particular, we establish SWIPT-enabled CF m-MIMO based system models by using FBC. We also formulate and solve the optimization problems for the tradeoff between the E-effective capacity and harvested energy for our proposed statistical delay and error-rate bounded QoS provisioning mechanisms. The obtained simulation results validate and evaluate our developed schemes.
