R15里只说明了当重复PUCCH和PUSCH冲突时如何处理,以及重复PUCCH和其他PUCCH冲突时如何处理,但是如果重复PUCCH和PUSCH及其他PUCCH同时存在时该如何处理呢?先处理重复PUCCH和PUSCH冲突还是先处理重复PUCCH和其他PUCCH的冲突?

R17里213是有明确说明逻辑的。

When a UE determines overlapping for PUCCH and/or PUSCH transmissions of the same priority index other than PUCCH transmissions with SL HARQ-ACK reports before considering limitations for UE transmission as described in clauses 11.1, 11.1.1, 11.2A, 15 and 17.2 including repetitions if any,
- first, the UE resolves the overlapping for PUCCHs with repetitions as described in clause 9.2.6, if any
- second, the UE resolves the overlapping for PUCCHs without repetitions as described in clauses 9.2.5
- third, the UE resolves the overlapping for PUSCHs and PUCCHs with repetitions as described in clause 9.2.6
- fourth, the UE resolves the overlapping for PUSCHs and PUCCHs without repetitions as is subsequently
described in this clause.

R15感觉也是按照这个来的,不过没明确这么说。R15里9.2.6里也一样提到
A UE does not multiplex different UCI types in a PUCCH transmission with repetitions over PUCCH repeat > 1 slots.

这里相当于是R17里的STEP1了,解决完之后就不存在重复PUCCH和PUCCH重叠的情况了
