Sidelink communication method and communication device

A sidelink communication method, comprising:

• receiving, by a second terminal device, assistance information from a first terminal device in a first time interval, wherein the first time interval is a time interval configured to transmit the assistance information, the assistance information is configured to indicate a resource set, and the resource set comprises one or more of:
• a resource preferred by the first terminal device,
• a resource not preferred by the first terminal device or
• a conflicting resource;
• wherein the first time interval is in an active time of a discontinuous reception (DRX) operation of the second terminal device,
• wherein the method further comprises:
• transmitting, by the second terminal device, first indication information to the first terminal device, wherein the first indication information is configured to indicate a first time-frequency resource, and the first time-frequency resource is a reserved resource of the second terminal device;
• wherein the first time interval is prior to the first time-frequency resource,
• wherein an interval between an ending moment of the first time interval and a starting moment of the first time-frequency resource is greater than or equal to a second time interval, and the second time interval is a minimum time interval required by the second terminal device to perform a resource reselection.

A communication device, the communication device being a first terminal device and comprising:

• a processor;
• a memory, configured to store a computer execution instruction;
• an interface, configured to communicate with a second terminal device;
• wherein the processor is configured to execute the computer execution instruction stored in the memory, to implement:
• transmitting assistance information to the second terminal device in a first time interval, wherein the assistance information is configured to indicate a resource set, and the resource set comprises one or more of:
• a resource preferred by the first terminal device,
• a resource not preferred by the first terminal device or
• a conflicting resource;
• wherein the first time interval is in an active time of a discontinuous reception (DRX) operation of the second terminal device,
• wherein the processor is further configured to execute the computer execution instruction stored in the memory, to implement:
• receiving first indication information from the second terminal device, wherein the first indication information is configured to indicate a first time-frequency resource, and the first time-frequency resource is a reserved resource of the second terminal device;
• wherein the first time interval is prior to the first time-frequency resource,
• wherein an interval between an ending moment of the first time interval and a starting moment of the first time-frequency resource is greater than or equal to a second time interval, and the second time interval is a minimum time interval required by the second terminal device to perform a resource reselection.
