Abstract

Millimeter-wave communication is considered one of the key enablers for 5G systems as it contributes to achieving high data rate with very wideband transmission, high beamforming gain and massive MIMO techniques. Further, millimeter-wave technology can also be used for the accurate positioning. However, it is yet unclear how communication and positioning systems can share resources to flexibly fulfill data-rate and quality-of-position requirements, especially, in multiuser scenarios. In this regard, the objective of this paper is to investigate and quantify the trade-off between positioning quality and achievable sum-rate as a function of number of receive antennas and transmitter locations in an uplink multi-user scenario.
