Abstract

Reflecting intelligent surface (RIS) assisted millimeter wave (mmWave) device to device (D2D) communication in single input single output (SISO) mode is considered. RIS can bypass the blocked D2D pairs since mmWaves are highly susceptible to blockages. However, the RIS is composed of passive elements which cannot accurately measure the state of the given channel and may suffer outages from moving obstacles (blockages) or due to moving devices (communication out of range) causing uncertainty in link quality. Each data packet will have some probability to be successfully transmitted towards the destination device via a RIS in each time unit. When a packet is lost it has to be re-transmitted which will induce extra delay. In this paper, the impact of link success probability on delay is studied. A lower bound on delay such that all packets are received successfully for the given link success probability has been derived. Later, we have derived a new term called apparent success probability which captures the trade-off between delay and link success probability. Simulations are performed which conforms with the derived theoretical results.
