Method for processing random access procedure, and terminal device

A method for processing a random access procedure, applied to a terminal device, a MAC entity of the terminal device being configured to have a skipUplinkTxDynamic field, and a value of the skipUplinkTxDynamic field being true;

• the method comprising:
• in a non-contention random access procedure satisfying a predetermined condition, after receiving a random access response (RAR), if there is no data to be uplink transmitted, not performing uplink transmission,
• wherein the predetermined condition comprises that the non-contention random access procedure is initiated by a physical downlink control channel (PDCCH) order, wherein the data to be uplink transmitted comprises at least one of uplink data that the terminal device needs to send medium access control (MAC) control element (CE), and padding data;
• in the random access procedure initiated by the PDCCH order whose random access preamble index is not zero, when a UL grant indicated to an HARQ entity is addressed to an RA-RNTI, not generating, by the MAC entity of the terminal device, a MAC PDU for the HARQ entity.

A terminal device, comprising:

• a non-transitory memory, storing a computer program;
• a transceiver;
• a processor, coupled to the non-transitory memory cell and the transceiver, wherein the processor is configured to call and run the computer program from the memory to perform:
• in a non-contention random access procedure satisfying a predetermined condition, after receiving a random access response (RAR), when that there is no data to be uplink transmitted, not performing uplink transmission,
• wherein the predetermined condition comprises that the non-contention random access procedure is initiated by a physical downlink control channel (PDCCH) order, wherein the data to be uplink transmitted comprises at least one of uplink data that the terminal device needs to send medium access control (MAC) control element (CE), and padding data.
