A method and apparatus for UCI
multiplexing in a
wireless communication node are disclosed. The communication node receives a first signaling, a first PUCCH is a PUCCH for a first UCI, the first PUCCH depends on the first signaling; the communication node transmits a plurality of PUSCHs, the plurality of PUSCHs overlap with the first PUCCH; wherein the first UCI is multiplexed on one PUSCH of the plurality of PUSCHs, the PUSCH of the plurality of PUSCHs for
multiplexing the first UCI depends on whether a first type of
orthogonal sequence is applied to the plurality of PUSCHs, the first type of
orthogonal sequence is an
orthogonal sequence of a PUSCH.
