Power efficiency has become an important design goal for wireless communications, and a coordinated multi-point (CoMP) with joint transmission (JT) scheme can be implemented to improve the cell edge throughput by increasing the signal-to-interference ratio, which in turn leads to power savings through cooperative transmission. To this end, we propose a power control scheme in which the cooperating base station can reduce its own transmission power while remaining within two stage quality of service (QoS) constraints, including the call-blocking probability and outage probability. For the two QoS constraints, we introduce call admission control and signal-to-interference ratio models for CoMP-JT that consider a two-dimensional Markov chain and the sum of multiple exponential random components. The results of the call blocking and outage probabilities are used to obtain the power consumption model and analyse the performance for the CoMP-JT with the proposed power control technique. Both the analytical and numerical results show that the proposed power control strategy can reduce the power consumption for the cellular network with the two stage QoSs.

Third Generation Partnership Project (3GPP) standardizes the Long‐Term Evolution (LTE) to improve the quality of service in modern communication systems using 3GPP LTE‐advanced (LTE‐A) networks. As this technology is converging with modern devices, efficient resource allocation schemes are essential for minimization of the communication delay for the sensitive real‐time devices. To achieve the demands of latest technologies, this paper proposes two novel mechanisms, enhanced real‐time polling system with continuous time–batch Markovian arrival process and proactive resource allocation framework. The objective of the former mechanism is to improvise the service connectivity between the multimedia devices in LTE‐A networks and the latter is to exploit the transmission bits in each user's buffer in addition to the state information of wireless channel. The proposed mechanisms consider the constraints enforced by 3GPP standard in terms of radio resource blocks allocation for LTE‐A networks. In addition, the proposed mechanisms use LTE‐A networks to investigate the Voice over LTE traffic in order to analyze various quality‐of‐service measures, namely, sum throughput, session setup delay, packet delivery ratio, resource utilization ratio, and throughput improvement via real‐time multimedia client‐server systems. The probing results show that the proposed algorithm is superior in comparison to other typical services of IEEE 802.16d/e–based systems as well as LTE‐A system with 7 orthogonal frequency‐division multiplexing symbols over a duration slot 0.5 ms. While the slotted duration is set to 5 ms, the proposed framework effectively utilizes the resource allocation cycle to support the uplink scheduling to outperform at least 38% better throughput performance in comparison with existing mechanisms.
