Abstract

A random access (RA) scheme exhibiting a non-isometric frame duration and a low latency. The RA and data messages have a duration with a different time unit and the time slot of the RA message is much shorter than the duration of one data frame. A specific signature, which is designed to be robust against the collisions, is transmitted during the RA request, the signature being either a unique sequence or a compressed signature. The user equipment device transmits the data message immediately after receiving its resource through a frame structure showing a time misalignment between adjacent data frames located in different or identical frequency sub-bands. A frequency guard band is inserted between its resource and an adjacent resource assigned to another user equipment device, the frequency guard band having an adaptive size according to the level of time misalignment and its impact on the distortion.
