Assignee: HUAWEI TECHNOLOGIES CO., LTD.
Field: Digital communication (Electrical engineering)
Classification: CPC H | IPC H

Claim 14:
15. A data transmission apparatus, comprising:
at least one processor; and
a memory storing computer-executable instructions, wherein the computer-executable instructions, when executed by the at least one processor, cause the data transmission apparatus to:
send 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;
receive, 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;
send a first Msg 3 including both signaling and the first user data;
send 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;
receive, 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
send a second Msg 3 including signaling to the base station,
wherein the second Msg 3 includes a radio resource control (RRC) connection request signaling,
wherein the computer-executable instructions, when executed by the at least one processor, further cause the data transmission apparatus to:
after sending the second Msg 3, receive a Msg 4 carrying an RRC connection setup signaling,
receive a fourth uplink scheduling information, wherein the fourth uplink scheduling information is used by the terminal device to send the second user data, and
send the second user data to the base station.
