TOPIC 1: Exploiting Joint Base Station equipped Multiple Antenna and Full-Duplex D2D users

We investigate power domain division based multiple access (PDMA) to support the base station (BS) equipped multiple antenna to serve mobile users. Such system deploys multiple input single output (MISO) based wireless transmission and full-duplex (FD) scheme. Furthermore, such MISO PDMA system consisting of BS employing transmit antenna selection to reduce complexity in signal processing at the receivers. We divide two kinds of mobile users, device-to-device (D2D) user and traditional users. In such MISO PDMA, it exists trade-off between outage performance of each PDMA user and power allocation factors.

TOPIC 2: Relay selection in wireless networks

In this work, we study joint user-relay selection and association in multi-user multiple access at downlinks. The proposed scheme is sub-optimal and utilizes only the channel gains known between the nodes, which leads to reduced feedback and overhead in comparison to schemes that require full channel knowledge. As important finding, the complexity of the scheme scales linearly as the product of the total number of relays, the total number of users and the number of selected users.
