Resource selection method and terminal device

A resource selection terminal device, comprising:

• a processor;
• and
• a non-transitory computer-readable storage medium storing a program to be executed by the processor, the program including instructions for:
• detecting a plurality of resource locations before receiving a higher layer request;
• receiving the higher layer request, wherein the higher layer request notifies the terminal device that there is to-be-transmitted data and that a sending resource needs to be selected for the to-be-transmitted data;
• obtaining, based on the plurality of resource locations, a first set in a first time window after the higher layer request is received, wherein obtaining the first set in the first time window comprises:
• detecting that a resource mapped in at least one of the plurality of resource locations is a resource in the first time window;
• determining that all reserved resources for sending subsequent data that are respectively indicated by N pieces of successfully decoded scheduling assignment information used before the higher layer request is received belong to a set comprising the resource mapped in the at least one resource location;
• and
• determining, as the first set, all resources in the set comprising the resource mapped in the at least one resource location except a resource in a second set, wherein the second set comprises a sum of the reserved resources indicated by the N pieces of successfully decoded scheduling assignment information, and N is a positive integer;
• determining that a quantity of resources in the first set is less than a preset first threshold;
• and
• in response to determining that the quantity of resources in the first set is less than the preset first threshold, randomly selecting a resource from a resource pool for sending the to-be-transmitted data.

• determining that a quantity of resources in the first set is less than a preset first threshold, wherein the preset first threshold is a quantity of resources in a second set, and the second set is usable by the terminal device to select the sending resource from the second set;
• and
• in response to determining that the quantity of resources in the first set is less than the preset first threshold, selecting a resource for sending the to-be-transmitted data from the first set, wherein the selected resource for sending the to-be-transmitted data is not reserved to be used by the terminal device for sending subsequent data.
