Abstract
Methods, apparatuses and computer program provide for random access in a wireless communication system. A method implemented in a network device comprises receiving, from a terminal device, a signal for initiating an RA procedure of a first RA type, the signal including a preamble portion and an information portion. In response to successfully detecting the preamble portion of the signal, but failure in detection of the information portion of the signal, transmitting to the terminal device a first response indicating a successful detection of only a preamble portion of the signal, or a second response indicating an RA procedure of a second RA type different from the first RA type. The described technique may increase the reliability of a two-step RACH procedure and/or reduce consumption of time-frequency resources.
