On the Performance of PDCCH in LTE and 5G New Radio
5G New Radio (NR) Release 15 has been specified in June 2018. It introduces
numerous changes and potential improvements for physical layer data
transmissions, although only point-to-point (PTP) communications are
considered. In order to use physical data channels such as the Physical
Downlink Shared Channel (PDSCH), it is essential to guarantee a successful
transmission of control information via the Physical Downlink Control Channel
(PDCCH). Taking into account these two aspects, in this paper, we first analyze
the PDCCH processing chain in NR PTP as well as in the state-of-the-art Long
Term Evolution (LTE) point-to-multipoint (PTM) solution, i.e., evolved
Multimedia Broadcast Multicast Service (eMBMS). Then, via link level
simulations, we compare the performance of the two technologies, observing the
Bit/Block Error Rate (BER/BLER) for various scenarios. The objective is to
identify the performance gap brought by physical layer changes in NR PDCCH as
well as provide insightful guidelines on the control channel configuration
towards NR PTM scenarios.Comment: Globecomm 2018 workshop, 6 pages, 7 fig
