Time-frequency resource determining method and apparatus

A time-frequency resource determining method, wherein the method comprises:

• receiving, by a second terminal, a timing offset sent by a first terminal;
• determining, by the second terminal, a second timing based on the timing offset and a first timing;
• determining, by the second terminal based on the first timing and the second timing, that a first time-frequency resource partly or completely overlaps a second time-frequency resource in time domain, wherein
• the first time-frequency resource is determined by the first terminal based on the first timing, and the first time-frequency resource is a time-frequency resource for communication between the first terminal and the second terminal;
• and
• the second time-frequency resource is determined by the first terminal based on the second timing, and the second time-frequency resource is a time-frequency resource for communication between the first terminal and a base station;
• and
• in response to determining that the first time-frequency resource partly or completely overlaps the second time-frequency resource in time domain stop using, by the second terminal, the first time-frequency resource to communicate with the first terminal and using, by the second terminal, a third time-frequency resource for communication with the second terminal, wherein the third time-frequency is determined by the base station based on second time-frequency resource.

A time-frequency resource determining method, wherein the method comprises:

• determining, by a base station, a third time-frequency resource, wherein the third time-frequency resource is determined by the base station based on a first timing, and the third time-frequency resource is a time-frequency resource used for communication between a first terminal and a second terminal;
• determining, by the base station, a second time-frequency resource, wherein the second time-frequency resource is determined by the base station based on a second timing, and the second time-frequency resource is a time-frequency resource used for communication between the first terminal and the base station;
• determining, by the base station, that the third time-frequency resource does not overlap the second time-frequency resource in time domain;
• and
• sending, by the base station, resource configuration information to the first terminal, wherein the resource configuration information is used to instruct to use the third time-frequency resource for communication between the first terminal and the second terminal after the first terminal determines that the second time-frequency resource is partly or completely overlaps a first time-frequency resource in time domain.
