at least one processor; and

at least one memory storing instructions, that when executed by the at least one processor, cause the device to:

transmit a random access request from the device to a further device, the random access request comprising a preamble of the device;

receive a random access response to the random access request from the further device, the random access response comprising an indication as to the number of transmission opportunities granted for a set of devices of which random access requests are responded,

wherein the indication is indicating the number of transmission opportunities with a time domain offset from an uplink grant, and

wherein one of the number of transmission opportunities are of a continuous uplink grant following the uplink grant, or the number of transmission opportunities with a frequency offset to resources physical resource blocks is provided in the uplink grant;

in response to determining that the random access response comprises a preamble identification of the device, determine the number of transmission opportunities granted for the device based on the indication; and

determine a set of transmission resources for the device based at least in part on the number of the transmission opportunities.
