Abstract
Wireless full-duplex transmission has the potential to double the system throughput compared with the conventional half-duplex transmission. To achieve the maximum potential system throughput, optimal power allocation taking into account quality-of-service (QoS) is urgently needed. In this paper, we propose the QoS driven power allocation schemes for wireless full-duplex bidirectional links. By integrating information theory with the statistical QoS principle, we build two models — local transmit power related self-interference (LTPRS) model and local transmit power unrelated self-interference (LTPUS) model to analyze the wireless full-duplex transmission. For both of these two models, we derive the optimal power allocation schemes, which aim at maximizing the system throughput subject to the given delay-QoS constraint, over wireless bidirectional links with full-duplex transmission. The analyses and numerical results verify that our proposed power allocation scheme can efficiently support diverse QoS requirements over wireless bidirectional links. Our proposed fullduplex QoS driven power allocation schemes can obtain larger effective capacity compared with the conventional half-duplex transmission over wireless bidirectional links.
