1. A method performed by a terminal device, the method comprising:
performing a transmission of a message to a network node in a random access procedure, wherein the transmission of the message comprises transmission of a preamble and transmission of a payload on a shared channel;
receiving a response message from the network node, the response message comprising:
an identifier of the preamble;
one or more responses intended for one or more terminal devices, respectively; and
information about a radio network temporary identifier to indicate a retransmission of the payload on the shared channel; and
performing the retransmission of the payload on the shared channel to the network node in response to the response message, wherein the retransmission is according to retransmission configuration comprising:
a resource configuration indicated by predetermined configuration information for the terminal device, and wherein a redundancy version indicated by the predetermined configuration information is used for the retransmission of the payload; and
a resource configuration indicated by the response message.
