Abstract

Embodiments provide apparatuses, methods, and computer programs for a receiver and a transmitter of a wireless system. An apparatus (10) for a receiver (100) of a wireless communication system comprises means for receiving (12) radio signals, which are organized in repetitive radio frames, a radio frame being subdivided in sub-frames. The apparatus (10) further comprises means for extracting (14) a first payload data packet from the received radio signals using a single sub-frame of the received radio signals and for extracting a second payload data packet using two or more sub-frames of two or more radio frames. An apparatus (20) for a transmitter (200) comprises means for obtaining (22) information on a subset of radio resources for scheduled and/or non-scheduled transmission. The apparatus (20) further comprises means for transmitting (24) radio signals, which are organized in repetitive radio frames, a radio frame being subdivided in sub-frames, the means for transmitting (24) is operable to transmit a first payload data packet using a single sub-frame of the radio signal and for transmitting a second payload data packet using two or more sub-frames.
