Random access in a wireless communication network

A method performed by a radio network node, the method comprising:

• transmitting multiple synchronization and signal blocks (SSBs);
• and
• transmitting, from the radio network node to a wireless communication device, a random access configuration which configures the wireless communication device with a set of one or more random access preambles that is not associated with any of the multiple SSBs, wherein the random access configuration indicates the set of one or more random access preambles that is not associated with any of the multiple SSBs,
• wherein the random access configuration, or the set of one or more random access preambles, is specific for a random access procedure that is of a certain type and/or for a certain type of service wherein the certain type of random access procedure is either:
• a two-step random access procedure in which a random access preamble and a payload are transmitted by the wireless communication device in a first step and a random access response is received by the wireless communication device in a second step occurring after the first step;
• or
• a contention-free random access procedure.

A wireless communication device comprising:

• communication circuitry;
• and
• processing circuitry configured to receive, via the communication circuitry, from a radio network node configured to transmit multiple synchronization and signal blocks (SSBs), a random access configuration which configures the wireless communication device with a set of one or more random access preambles that is not associated with any of the multiple SSBS, wherein the random access configuration indicates the set of one or more random access preambles that is not associated with any of the multiple SSBs,
• wherein the random access configuration, or the set of one or more random access preambles, is specific for a random access procedure that is of a certain type and/or for a certain type of service, wherein the certain type of random access procedure is either:
• a two-step random access procedure in which a random access preamble and a payload are transmitted by the wireless communication device in a first step and a random access response is received by the wireless communication device in a second step occurring after the first step;
• or
• a contention-free random access procedure.
