Network node, wireless device and method for use in a random access procedure therebetween in a cell of the network node

A wireless device for performing a Random Access, RA, procedure with a network node in a cell of the network node, the wireless device comprising:

• a processor;
• and
• a memory, the processor and the memory configured to:
• transmit, to the network node, an RA message comprising an RA preamble;
• receive, from the network node, an RA Response, RAR, comprising a Temporary Cell Radio Network Temporary Identifier, TC-RNTI, and an RA preamble identifier identifying the RA preamble;
• transmit, to the network node, a connection request message comprising a temporary identity;
• receive, from the network node;
• an RA4 message comprising the temporary identity;
• an indication that a plurality of subsequent RA4 messages will be transmitted in response to connection request messages;
• and
• one of (I) a C-RNTI for the wireless device, and (II) a new TC-RNTI, the TC-RNTI that previously was received being promoted to be a C-RNTI for the-wireless device, the temporary identity in the RA4 message and the indication of the plurality of subsequent RA4 messages being configured to indicate:
• which wireless device the one of the C-RNTI and the new TC-RNTI is intended for;
• and
• that an additional subsequent RA4 message is to be expected for the other wireless devices that the one of the C-RNTI and the new TC-RNTI is not intended for;
• and
• transmit, to the network node, a Connection Setup Complete message if the temporary identity comprised in the received RA4 message matches the temporary identity in the transmitted connection request message,
• wherein the wireless device is further configured to
• receive, from the network node, the RA4 message comprising a temporary identity not being the temporary identity of the wireless device, and an indication that at least one additional RA4 message will be transmitted, and in response to receiving the indication that at least one additional RA4 message will be transmitted, listening for a RA4 message comprising the temporary identity of the wireless device.
