In state-of-the-art mobile devices (MDs), non-radio contexts (i.e., non-real-time data) provided by various sensors have been excluded in determining the modem configuration because of the problems in applying them in real-time modem operations. This paper presents a reconfiguration procedure and hardware implementation of a European Telecommunications Standards Institute (ETSI)-standard reconfigurable MD with a multi-antenna system. Borrowing the ETSI-standard architecture, the proposed MD can exploit a high-level abstraction of configuration-related operations, which consequently provides its application processor operating in non-real-time domain a uniform way of managing the multi-antenna-related hardware platform operating in real time. The configuration of the proposed MD is determined in accordance with non-radio and radio context information for opportunistically utilizing multiple antenna resources. From an implemented multi-antenna MD system operating in an indoor layout and computer simulations of the multi-antenna MD operating in a modeled outdoor layout, we verify that the MD configuration can be optimized in accordance with radio and non-radio contexts not only for fixed indoor but also for mobile outdoor environments. This enables the multi-antenna MD to efficiently utilize its antenna resources, such that the throughput maximization and/or power consumption minimization can be achieved.
