Random access method, apparatus, and storage medium

A communications apparatus, comprising:

• a transmitter, configured to:
• send a random access request, wherein the random access request comprises a preamble and uplink data;
• and
• a receiver, configured to:
• receive first downlink control information (DCI), wherein the first DCI comprises first indication information that indicates a type of response that a physical downlink shared channel (PDSCH) carries;
• receive a message comprising response information for the random access request, wherein the response information is carried on the PDSCH, and
• when the type of the response indicated by the first indication information in the DCI matches a type of the random access request, demodulating the PDSCH,
• the response information is sent after the uplink data is successfully decoded by a network device,
• the response information comprises a contention resolution identity and first information, and
• the first information comprises information indicating a resource used to feed back an acknowledgement message and a transmit power control (TPC) command, wherein the information indicating the resource used to feed back the acknowledgement message is for determining a time-frequency resource of a physical uplink control channel (PUCCH) that carries the acknowledgement message, and the TPC command indicates a power control adjustment factor for determining transmit power of the PUCCH.

A non-transitory computer-readable storage medium, storing a program, wherein when the program is read and executed by a communications apparatus, the communications apparatus is enabled to implement operations comprising:

• sending a random access request to a network device, wherein the random access request comprises a preamble and uplink data;
• receiving first downlink control information (DCI), wherein the first DCI comprises first indication information that indicates a type of response that a physical downlink shared channel (PDSCH) carries;
• receiving a message comprising response information for the random access request, wherein the response information is carried on the PDSCH;
• and
• when the type of the response indicated by the first indication information in the DCI matches a type of the random access request, demodulating the PDSCH, wherein:
• the response information is sent after the uplink data is successfully decoded by the network device,
• the response information comprises a contention resolution identity and first information, and
• the first information comprises information indicating a resource used to feed back an acknowledgement message and a transmit power control (TPC) command, wherein the information indicating the resource used to feed back the acknowledgement message is for determining a time-frequency resource of a physical uplink control channel (PUCCH) that carries the acknowledgement message, and the TPC command indicates a power control adjustment factor for determining transmit power of the PUCCH.
