Consider a device to device (D2D) link which utilizes the mode selection to\ndecide between the direct mode and cellular mode. This paper investigates the\nimpact of mode selection on effective capacity (EC) (the maximum sustainable\nconstant arrival rate at a transmitters queue under statistical quality of\nservice constraints) of a D2D link for both overlay and underlay scenarios. Due\nto lack of channel state information, the transmit device sends data at a fixed\nrate and fixed power; this fact combined with mode selection makes the D2D\nchannel a Markov service process. Thus, the EC is obtained by calculating the\nentries of the transition probability matrix corresponding to the Markov D2D\nchannel. Numerical results show that the EC decays exponentially (and the gain\nof overlay D2D over underlay D2D diminishes) with the increase in estimation\nerror of the pathloss measurements utilized by the mode selection.\n
