Asynchronous uplink transmission method, device, and storage medium

An asynchronous uplink transmission method, wherein the method comprises:

• sending, by a network device, configuration information of a physical uplink shared channel (PUSCH) used for asynchronous uplink transmission, wherein the configuration information comprises a length of a cyclic prefix (CP) of the PUSCH, and the length of the CP of the PUSCH is less than a length of a CP of a random access preamble;
• and
• receiving, by the network device, the PUSCH sent based on the configuration information of the PUSCH,
• wherein the method further comprises:
• sending, by the network device, group common downlink control information (DCI) scrambled by using a first radio network temporary identifier (RNTI), wherein the group common DCI carries feedback information for the PUSCH, a location of the feedback information for the PUSCH in the group common DCI is determined based on a number of a demodulation reference signal for the PUSCH, and the first RNTI is determined based on a time-frequency resource for the PUSCH;
• or
• sending, by the network device, first DCI scrambled by using a second RNTI, wherein the first DCI carries feedback information for the PUSCH, and the second RNTI is determined based on a time-frequency resource for the PUSCH and a number of a demodulation reference signal for the PUSCH;
• or
• sending, by the network device, second DCI used for scheduling a first physical downlink shared channel (PDSCH) and the first PDSCH, wherein the first PDSCH carries feedback information for the PUSCH, and the feedback information comprises a number of a demodulation reference signal for the PUSCH and hybrid automatic repeat request (HARQ) feedback information for the PUSCH;
• or
• sending, by the network device, third DCI used for scheduling a second PDSCH and the second PDSCH, wherein the second PDSCH carries feedback information for the PUSCH, and the feedback information comprises an identity of a UE and HARQ feedback information for the PUSCH.

A network device, comprising:

• a transmitter, configured to send configuration information of a physical uplink shared channel (PUSCH) used for asynchronous uplink transmission, wherein the configuration information comprises a length of a cyclic prefix (CP) of the PUSCH, and the length of the CP of the PUSCH is less than a length of a CP of a random access preamble;
• and
• a receiver, configured to receive the PUSCH sent based on the configuration information of the PUSCH,
• wherein the transmitter is further configured to:
• send group common downlink control information (DCI) scrambled by using a first radio network temporary identifier (RNTI), wherein the group common downlink control information carries feedback information for the PUSCH, a location of the feedback information for the PUSCH in the group common downlink control information is determined based on a number of a demodulation reference signal for the PUSCH, and the first RNTI is determined based on a time-frequency resource for the PUSCH;
• or
• send first DCI scrambled by using a second RNTI, wherein the first DCI carries feedback information for the PUSCH, and the second RNTI is determined based on a time-frequency resource for the PUSCH and a number of a demodulation reference signal for the PUSCH;
• or
• send second DCI used for scheduling a first physical downlink shared channel (PDSCH) and the first PDSCH, wherein the first PDSCH carries feedback information for the PUSCH, and the feedback information comprises a number of a demodulation reference signal for the PUSCH and hybrid automatic repeat request (HARQ) feedback information for the PUSCH;
• or
• send third DCI used for scheduling a second PDSCH and the second PDSCH wherein the second PDSCH carries feedback information for the PUSCH, and the feedback information comprises an identity of UE and HARQ feedback information for the PUSCH.
