Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 8:
9. A method, comprising:
sending a first random access request to a base station, wherein the first random access request is used to request first uplink scheduling information that indicates a terminal device uses a first transport block to transmit first user data in Msg 3, and the first transport block is used to transmit both signaling and user data;
receiving, from the base station, a first random access response in response to the first random access request, wherein the first random access response carries the first uplink scheduling information;
sending a first Msg 3 including both signaling and the first user data;
sending a second random access request to the base station, wherein the second random access request is used to request second uplink scheduling information that indicates the terminal device uses a second transport block to transmit second user data in Msg 3, and the second transport block is used to transmit both signaling and user data;
receiving, from the base station, a second random access response in response to the second random access request, wherein the second random access response carries a third uplink scheduling information that indicates the terminal device uses a third transport block to transmit Msg 3, and the third transport block is used to transmit signaling, but is not used to transmit the second user data; and
sending a second Msg 3 including signaling to the base station,
wherein the second Msg 3 includes a radio resource control (RRC) connection request signaling; and
after sending the second Msg 3 to the base station, the method further comprises:
receiving, from the base station, a Msg 4 carrying an RRC connection setup signaling;
receiving, from the base station, a fourth uplink scheduling information, wherein the fourth uplink scheduling information is used to send the second user data; and
sending the second user data to the base station.
