Random access procedure

A method performed by a base station to support random access by wireless devices to a wireless communication network, the method comprising:

• based on a physical random access channel (PRACH) configuration that is associated with a first index, receiving a random access preamble from a wireless device in an uplink (UL) bandwidth part (BWP) of a carrier;
• selecting one or more downlink (DL) BWPs of the carrier based on an association between the first index and the one or more DL BWPs;
• and
• transmitting respective one or more random access responses in the one or more DL BWPs.

A wireless device configured for random access to a wireless communications network, the wireless device comprising:

• transceiver circuitry configured to communicate with the wireless communications network;
• and
• processing circuitry operably coupled to the transceiver circuitry, whereby the processing circuitry and the transceiver circuitry are configured to:
• using a physical random access channel (PRACH) configuration that is associated with a first index, transmit a random access preamble to the wireless communication network in an uplink (UL) bandwidth part (BWP) of a carrier;
• select a first downlink (DL) BWP of the carrier based on an association between the first index and the first DL BWP;
• and
• monitor the first DL BWP for a random access response from the wireless communication network.
