It should be noted that, the first resource determined according to the non-listening resource may be completely in the candidate resource set, where the first resource may be excluded. And if the first resource determined according to the non-monitoring resource falls in the candidate resource set partially and the first resource falls outside the candidate resource set partially, excluding the first resource falling in the candidate resource set from the candidate resource set, and then the remaining resources in the candidate resource set are the first resource set.
