Abstract

A communication method and a system for converging a 5th-Generation (5G) communication system for supporting higher data rates beyond a 4th-Generation (4G) system with a technology for Internet of Things (IoT) are provided. The system may be applied to intelligent services based on the 5G communication technology and the IoT-related technology, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. The method includes receiving, from a base station, scheduling information for a first uplink packet transmission in a first time slot, determining whether the first uplink packet transmission in the first time slot is restricted based on information corresponding to a second uplink packet transmission in the first time slot of another terminal, and if the first uplink packet transmission in the first time slot is restricted, skipping the first uplink packet transmission in a first time slot.

Claims

1. A communication method of a terminal, the method comprising:

receiving, from a base station, scheduling information for a first uplink packet transmission in a first time slot;

determining whether the first uplink packet transmission in the first time slot is restricted based on information corresponding to a second uplink packet transmission in the first time slot of another terminal; and

if the first uplink packet transmission in the first time slot is restricted, skipping the first uplink packet transmission in a first time slot.

2. The method of claim 1, further comprising:

receiving, from the base station, the information corresponding to the second uplink packet transmission in the first time slot of the other terminal in a second time slot preceding the first time slot.

3. The method of claim 1,

wherein the information corresponding to the second uplink packet transmission in the first time slot of the other terminal comprises indication indicating the terminal to skip the first uplink packet transmission in the first time slot.

4. The method of claim 1,

wherein the information corresponding to the second uplink packet transmission in the first time slot of the other terminal comprises information indicating that the first time slot is scheduled for the second uplink packet transmission of the other terminal.

5. A communication method of a base station, the method comprising:

transmitting, to a first terminal, first scheduling information for a first uplink packet transmission in a first time slot;

transmitting, to a second terminal, second scheduling information for a second uplink packet transmission in the first time slot;

determining whether the first uplink packet transmission in the first time slot is restricted based on the second scheduling information; and

if the first uplink packet transmission in the first time slot is restricted, receiving, from the second terminal, the second uplink packet transmission in the first time slot.

6. The method of claim 5, further comprising:

transmitting, to the first terminal, information corresponding to the second uplink packet transmission in the first time slot of the second terminal in a second time slot preceding the first time slot,

wherein the information corresponding to the second uplink packet transmission in the first time slot of the second terminal comprises an indication indicating the first terminal to skip the first uplink packet transmission in the first time slot.

7. The method of claim 5, further comprising:

transmitting, to the first terminal, information corresponding to the second uplink packet transmission in the first time slot of the second terminal in a broadcasting signal,

wherein the information corresponding to the second uplink packet transmission in the first time slot of the second terminal comprises information indicating that the first time slot is scheduled for the second uplink packet transmission of the second terminal.

8. A terminal comprising:

a transceiver configured to receive and transmit a signal; and

at least one processor configured to;

receive, from a base station, scheduling information for a first uplink packet transmission in a first time slot,

determine whether the first uplink packet transmission in the first time slot is restricted based on information corresponding to a second uplink packet transmission in the first time slot of another terminal, and

if the first uplink packet transmission in the first time slot is restricted, skip the first uplink packet transmission in a first time slot.

9. The terminal of claim 8, wherein the at least one processor is further configured to:

receive, from the base station, the information corresponding to the second uplink packet transmission in the first time slot of the other terminal in a second time slot preceding the first time slot.

10. The terminal of claim 8,

wherein the information corresponding to the second uplink packet transmission in the first time slot of the other terminal comprises an indication indicating the terminal to skip the first uplink packet transmission in the first time slot.

11. The terminal of claim 8,

wherein the information corresponding to the second uplink packet transmission in the first time slot of the other terminal comprises information indicating that the first time slot is scheduled for the second uplink packet transmission of the other terminal.

12. A base station comprising:

a transceiver configured to receive and transmit a signal; and

at least one processor configured to;

transmit, to a first terminal, first scheduling information for a first uplink packet transmission in a first time slot,

transmit, to a second terminal, second scheduling information for a second uplink packet transmission in the first time slot,

determine whether the first uplink packet transmission in the first time slot is restricted based on the second scheduling information, and

if the first uplink packet transmission in the first time slot is restricted, receive, from the second terminal, the second uplink packet transmission in the first time slot.

13. The base station of claim 12, wherein the at least one processor is further configured to:

transmit, to the first terminal, information corresponding to the second uplink packet transmission in the first time slot of the second terminal in a second time slot preceding the first time slot.

14. The base station of claim 13,

wherein the information corresponding to the second uplink packet transmission in the first time slot of the second terminal comprises an indication indicating the first terminal to skip the first uplink packet transmission in the first time slot.

15. The base station of claim 12,

wherein the at least one processor is further configured to:

transmit, to the first terminal, information corresponding to the second uplink packet transmission in the first time slot of the second terminal in a broadcasting signal, and

wherein the information corresponding to the second uplink packet transmission in the first time slot of the second terminal comprises information indicating that the first time slot is scheduled for the second uplink packet transmission of the second terminal.
