Abstract

Claims (36)

1. A method for authorization-free scheduling performed by a user equipment, the method comprising:

sending uplink data;

receiving downlink control information (DCI) issued by a base station, wherein the DCI is acknowledged ACK-DCI or non-acknowledged NACK-DCI, the ACK-DCI is used for indicating a transmission success of the uplink data, and the NACK-DCI is used for indicating a transmission failure of the uplink data; and

adjusting a number of resending times for the user equipment to resend next uplink data based on the DCI, wherein the number of resending times is set to:

a first target number of repetitions from a first repetition number set in response to determining that the DCI is the acknowledged ACK-DCI, and

a second target number of repetitions from a second repetition number set in response to determining that the DCI is the non-acknowledged NACK-DCI;

wherein the method further comprises:

obtaining a first number of repetitions and a second number of repetitions indicated by the base station;

generating the first repetition number set according to the first number of repetitions by a set generation rule; and

generating the second repetition number set according to the second number of repetitions by the set generation rule.

2. The method according to claim 1 , wherein the first repetition number set is different from the second repetition number set.

3. The method according to claim 1 , wherein a repetition number relation is predefined in the user equipment and is a relation between the first number of repetitions and the second number of repetitions; and

obtaining the first number of repetitions and the second number of repetitions indicated by the base station comprises:

obtaining the first number of repetitions indicated by the base station; and

obtaining the second number of repetitions according to the first number of repetitions and the repetition number relation.

4. The method according to claim 1 , wherein a repetition number relation is predefined in the user equipment and is a relation between the first number of repetitions and the second number of repetitions; and

obtaining the first number of repetitions and the second number of repetitions indicated by the base station comprises:

obtaining the second number of repetitions indicated by the base station; and

obtaining the first number of repetitions according to the second number of repetitions and the repetition number relation.

5. The method according to claim 1 , wherein each of the first repetition number set and the second repetition number set contains an initial number of repetitions, and the initial number of repetitions is the number of resending times configured when the base station performs authorization-free scheduling on the user equipment.

6. The method according to claim 1 , wherein the first repetition number set and the second repetition number set contain a difference factor, and the difference factor is a difference between the adjusted number of resending times and a second basic number of repetitions;

determining a first target difference factor from the first repetition number set according to repetition number indication information contained in the DCI in response to determining that the DCI is the acknowledged ACK-DCI, and obtaining the first target number of repetitions by adding the first target difference factor to the second basic number of repetitions; and

determining a second target difference factor from the second repetition number set according to repetition number indication information contained in the DCI in response to determining that the DCI is the non-acknowledged NACK-DCI, and obtaining the second target number of repetitions by adding the second target difference factor to the second basic number of repetitions.

7. The method according to claim 6 , wherein each of the first repetition number set and the second repetition number set contains a difference factor with a numerical value being 0.

8. The method according to claim 6 , wherein the quantity of difference factors larger than 0 in the first repetition number set is smaller than the quantity of difference factors larger than 0 in the second repetition number set.

9. An apparatus for authorization-free scheduling, comprising: a processor, and a memory configured to store an instruction executable by the processor; wherein the processor is configured to:

send uplink data,

receive downlink control information (DCI) issued by a base station, wherein the DCI is acknowledged ACK-DCI or non-acknowledged NACK-DCI, the ACK-DCI is used for indicating a transmission success of the uplink data, and the NACK-DCI is used for indicating a transmission failure of the uplink data,

adjust a number of resending times for the apparatus to resend next uplink data based on the DCI, wherein the number of resending times is set to:

a first target number of repetitions from a first repetition number in response to determining that the DCI is the acknowledged ACK-DCI, and

a second target number of repetitions from a second repetition number set in response to determining that the DCI is the non-acknowledged NACK-DCI;

wherein the processor is further configured to:

obtain a first number of repetitions and a second number of repetitions indicated by the base station;

generate the first repetition number set according to the first number of repetitions by a set generation rule; and

generate the second repetition number set according to the second number of repetitions by the set generation rule.

10. A non-transitory computer readable storage medium, storing instruction, the instruction when executed by a processor of a user equipment, cause the user equipment to perform the method according to claim 1 .
