Data transmission method, terminal, and RAN device

A device, comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions to:
• receive, in a discontinuous reception (DRX) active period, first grant information sent by a radio access network (RAN) device, wherein the first grant information is used for an initial transmission grant of first data;
• receive, in a retransmission active time, second grant information sent by the RAN device, wherein the second grant information is used for an initial transmission grant of second data, and the retransmission active time is an active time in which a terminal expects to receive a retransmission grant for the first data;
• and
• remain in an active state in an activation extension time, wherein the activation extension time is after the second grant information is received;
• and
• wherein the first grant information is used for a downlink initial transmission grant of the first data, and the retransmission active time comprises a downlink retransmission active time, and wherein the downlink retransmission active time is an active time in which the terminal expects to receive a downlink retransmission grant for the first data.

A radio access network (RAN) device, comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions to:
• send first grant information to a terminal in a discontinuous reception (DRX) active period, wherein the first grant information is used for initial transmission grant of first data;
• determine a retransmission active time, wherein the retransmission active time is an active time in which the terminal expects to receive a retransmission grant for the first data;
• and
• send second grant information to the terminal in the retransmission active time, wherein the second grant information is used for initial transmission grant of second data;
• and
• wherein the first grant information is used for a downlink initial transmission grant of the first data, and the retransmission active time comprises a downlink retransmission active time, and wherein the downlink retransmission active time is an active time in which the terminal expects to receive a downlink retransmission grant for the first data.

A non-transitory computer readable medium comprising a program, wherein the program is executable by a processor to:

• receive, in a discontinuous reception (DRX) active period, first grant information sent by a radio access network (RAN) device, wherein the first grant information is used for initial transmission grant of first data;
• receive, in a retransmission active time, second grant information sent by the RAN device, wherein the second grant information is used for initial transmission grant of second data, and the retransmission active time is an active time in which a terminal expects to receive a retransmission grant for the first data;
• and
• remain in an active state in an activation extension time that is after receiving of the second grant information;
• and
• wherein the first grant information is used for downlink initial transmission grant of the first data, wherein the retransmission active time comprises a downlink retransmission active time, and wherein the downlink retransmission active time is an active time in which the terminal expects to receive a downlink retransmission grant for the first data.
