1. A method for transmitting uplink control information in a physical uplink shared channel, comprising:
in response to channel state information part 2 (CSI-2) being configured to be transmitted in the physical uplink shared channel (PUSCH) and the physical uplink shared channel not having an uplink shared channel (UL-SCH), determining to transmit the CSI-2 according to an actual code rate of the CSI-2 and a preset threshold, wherein the PUSCH not having the UL-SCH refers to the PUSCH not carrying UL-SCH data;
wherein the actual code rate of the CSI-2 is determined according to a following formula:

OG Complex Work Unit Math
wherein QUCI is a bit number of the uplink control information (UCI), LUCI a bit number of a cyclic redundancy check (CRC) of the UCI, Qm is a modulation order corresponding to a modulation mode of the UCI, and Q′UCI is a number of modulation symbols of UCI after being bit-encoded, and the UCI comprises the CSI-2;
wherein the preset threshold is determined according to a predetermined code rate and a predetermined beta value, wherein the predetermined code rate refers to a code rate configured by a base station for a current CSI-2 transmission and is selected from a code rate table of the PUSCH, and the predetermined beta value is selected from a beta value configuration table corresponding to the CSI-2; and
wherein the transmission method further comprises: in response to the uplink control information being configured to be transmitted in the PUSCH in one slot and the one slot having a plurality of PUSCHs, determining one PUSCH among the plurality of PUSCHs to transmit the uplink control information according to one of following rules:
selecting first of the plurality of PUSCHs in the one slot along a time direction;
selecting a PUSCH with most time-frequency domain resources among the plurality of PUSCHs in the one slot, and in response to an existence of multiple PUSCHs with the most time-frequency domain resources, selecting first of the multiple PUSCHs with the most time-frequency domain resources along a time direction;
receiving a notification, sent by the base station through a signaling, for informing which PUSCH among the plurality of PUSCHs is used for transmitting the uplink control information; or
receiving an implied notification, sent by the base station and determined through an index of a control channel element where downlink control information is located, for informing which PUSCH among the plurality of PUSCHs is used for transmitting the uplink control information.
