Abstract
A resource selection method and apparatus for device-to-device/vehicle-to-everything communication supporting carrier aggregation are disclosed. The resource selection method includes: initializing at least two resource pools, wherein each resource pool corresponds to one carrier; excluding an expected-busy resource from each resource pool associated with a resource of which channel signal strength is greater than a comparison threshold during a sensing period; determining whether remaining resources of a candidate resource pool meet a criterion for stopping resource exclusion, wherein the candidate resource pool comprises a portion of or all the resource pools, and the criterion comprises that a criteria parameter of the candidate resource pool is greater than or equal to a preset threshold of the criteria parameter; selecting a resource subset from the remaining resources of the candidate resource pool when the criterion is met, and otherwise incrementing the comparison threshold.
