1. A method for performing random access in a network, the method being performed by a terminal device, the method comprising:

  • receiving a Synchronization Signal Block (SSB) at a first time instant, the SSB having a time index denoting a timewise position of the SSB within a burst of successively transmitted SSBs and having an SSB length defined by a downlink symbol length that differs from an uplink symbol length indicated in system information included in or transmitted in association with the SSB, wherein the time index is an integer value;

    computing a distance from the first time instant by multiplying a selected length by the value of the time index, the selected length being the uplink symbol length when the uplink symbol length exceeds the SSB length and otherwise being the SSB length, wherein the uplink symbol length and the SSB length are equal, or one is an integer multiple of the other;

    determining a transmission time as a function of the computed distance; and

    transmitting a random access preamble at the determined transmission time.
