Device testing

An apparatus comprising

• at least one processor;
• and
• at least one memory including instructions, the at least one memory and computer program code configured to, with the at least one processor, cause the apparatus at least to perform:
• enabling testing of at least one user equipment over a plurality of radio frames by:
• determining, for at least one candidate position in a current radio frame, if one or more signals are to be transmitted to the at least one user equipment, based, at least in part, on one or more probabilities associated with the at least one candidate position in the current radio frame;
• if it is determined, for the at least one candidate position in the current radio frame, that one or more signals are to be transmitted to the at least one user equipment, transmitting the one or more signals to the at least one user equipment using the at least one candidate position in the current radio frame;
• if it is determined, for the at least one candidate position in the current radio frame, that the one or more signals are not be transmitted to the at least one user equipment, determining if a maximum number of transmission failures has occurred, wherein a transmission failure is determined to have occurred when it is determined that no signals are transmitted or to be transmitted in a current radio frame;
• and
• if it is determined that the maximum number of transmission failures has occurred, transmitting the one or more signals to the at least one user equipment using the at least one candidate position in the current radio frame.
