1. An uplink control information (UCI) multiplexing method, performed by a terminal, wherein for a physical uplink shared channel (PUSCH) carrying a multi-slot transport block (TB), in case that the PUSCH and a physical uplink control channel (PUCCH) overlap in at least one slot, the UCI multiplexing method comprising:
determining resources required for UCI multiplexing on the PUSCH and an upper limit of resources used for UCI multiplexing on the PUSCH;
determining resources used for actual UCI transmission based on the resources required for UCI multiplexing on the PUSCH and the upper limit of resources used for UCI multiplexing on the PUSCH; and
transmitting the UCI on the PUSCH based on the resources used for the actual UCI transmission,
wherein the determining the resources required for UCI multiplexing on the PUSCH comprises any one of the followings: determining the resources required for UCI multiplexing on the PUSCH based on resources for the PUSCH in one slot; or determining the resources required for UCI multiplexing on the PUSCH based on resources for the PUSCH in a nominal transmission,
wherein determining the resources required for UCI multiplexing on the PUSCH based on resources for the PUSCH in one slot comprises: determining the resources required for UCI multiplexing on the PUSCH based on resources for the PUSCH in a first slot or a last slot; or, determining the resources required for UCI multiplexing on the PUSCH based on resources in a slot with a maximum or a minimum number of orthogonal frequency division multiplexing (OFDM) symbols among multiple slots corresponding to PUSCH transmission,
wherein determining the resources required for UCI multiplexing on the PUSCH based on resources for the PUSCH in the nominal transmission comprises: determining the resources required for UCI multiplexing on the PUSCH based on a number of OFDM symbols of the PUSCH in a nominal transmission without segmentation, wherein the nominal transmission is determined based on scheduling downlink control information (DCI) or configuration information,
wherein in case of determining the resources required for UCI multiplexing on the PUSCH based on the number of OFDM symbols of the PUSCH in one slot, determining the resources required for UCI multiplexing on the PUSCH based on a first formula or a second formula;
the first formula is

OG Complex Work Unit Math
the second formula is

OG Complex Work Unit Math
wherein R is the resources required for UCI multiplexing on the PUSCH, OUCI is the number of bits for UCI carried on the PUSCH, LUCI is the number of cyclic redundancy check (CRC) bits for the UCI, βoffsetPUSCH is a beta offset between data and the UCI, Nsymb, slotPUSCH is the number of OFDM symbols of the PUSCH in a first slot or is the maximum or minimum number of OFDM symbols in all the slots for PUSCH transmission, MSCUCI(l) is the number of sub-carriers (SC) used for UCI transmission in OFDM symbol l, CUCI-SCH is the number of code blocks for uplink shared channel (UL-SCH) of the PUSCH transmission, Kr is the r-th code block size for UL-SCH of the PUSCH transmission, N is the number of slots used for the PUSCH transmission.
