Communication method and communications apparatus for resource selection

A communication method, comprising:

• determining, by a first terminal device, a first parameter, wherein the first parameter indicates one or more of:
• a parameter of a sensing window, a parameter of a resource selection window, and a parameter of a first time window, and wherein the first time window comprises the sensing window and the resource selection window;
• selecting, by the first terminal device, a first resource from a first resource pool based on the first parameter;
• and
• transmitting, by the first terminal device, sidelink information on the first resource,
• wherein the first parameter comprises at least one of:
• a start time of the sensing window, an end time of the sensing window, a length of the sensing window, a start time of the resource selection window, an end time of the resource selection window, a length of the resource selection window, a start time of the first time window, an end time of the first time window, or a length of the first time window.

A communications apparatus, comprising:

• a processor configured to:
• determine a first parameter, wherein the first parameter indicates one or more of:
• a parameter of a sensing window, a parameter of a resource selection window, and a parameter of a first time window, and wherein the first time window comprises the sensing window and the resource selection window;
• determine a first resource pool from at least one resource pool based on the first parameter;
• and
• select a first resource from the first resource pool;
• and
• a transmitter configured to transmit sidelink information on the first resource,
• wherein the first parameter comprises at least one of:
• a start time of the sensing window, an end time of the sensing window, a length of the sensing window, a start time of the resource selection window, an end time of the resource selection window, a length of the resource selection window, a start time of the first time window, an end time of the first time window, or a length of the first time window.
