  • One-Way URLLC with Truncated Channel Inversion Power Control.
    arXiv: Information Theory, 2019
    Co-Authors: Chunhui Li, Shihao Yan, Xiangyun Zhou, Nan Yang, Riqing Chen
    Abstract:

    In this work, we consider one-way ultra-reliable and low-latency communication (URLLC), where only the transmission in one direction requires URLLC and the transmission in the opposite direction does not. In order to meet the low-latency requirement of the one-way URLLC, we propose to use a truncated channel inversion power control (CIPC) to eliminate the requirement and the associated overhead of the training-based channel estimation at the receiver, while utilizing the multi-Antenna Technique at the transmitter to enhance the communication reliability. We first derive the transmission outage probability achieved by the truncated CIPC by considering the impact of a finite blocklength and a maximum transmit power constraint. Then, we determine the optimal constant power of the received signals in the truncated CIPC, which minimizes the transmission outage probability. Our examination shows that the proposed truncated CIPC is an effective means to achieve the one-way URLLC, where the tradeoff among reliability, latency, and required resources (e.g., the required number of transmit Antennas, or the required maximum transmit power) is revealed.

  • smart Antenna technologies for future wireless systems trends and challenges
    IEEE Communications Magazine, 2004
    Co-Authors: Angeliki Alexiou, Martin Haardt
    Abstract:

    The adaptation of smart Antenna Techniques in future wireless systems is expected to have a significant impact on the efficient use of the spectrum, the minimization of the cost of establishing new wireless networks, the optimization of service quality, and realization of the transparent operation across multitechnology wireless networks. Nevertheless, its success relies on two considerations that have been often overlooked when investigating smart Antenna technologies: first, the smart Antennas features need to be considered early in the design phase of future systems (top-down compatibility); second, a realistic performance evaluation of smart Antenna Technique needs to be performed according to the critical parameters associated with future systems requirements (bottom-up feasibility). In this article an overview of the benefits of and most recent advances in smart Antenna transceiver architecture is given first. Then the most important trends in the adoption of smart Antennas in future system are presented, such as reconfigurability to varying channel propagation and network conditions, cross-layer optimization, and multi-user diversity, as well as challenges such as the design of a suitable simulation methodology and the accurate modeling of channel characteristics, interference, and implementation losses. Finally, market trends, future projections, and the expected financial impact of smart Antenna systems deployment are discussed.
