A method, comprising: determining a transmission mode to satisfy a code rate upper limit configured by a base station, for transmitting channel state information, CSI, first control information, and data information in a time slot in a multiplexing manner of a plurality of multiplexing manners on a physical channel (S204), wherein the plurality of multiplexing manners comprises: (a) a first manner including performing a jointly encoding transmission on the first control information and all information of the CSI on the physical channel, in response to the CSI transmitted on the physical channel including at least one of wideband CSI or partial-band CSI; and (b) a second manner including (i) performing the jointly encoding transmission on the first control information and first part of information of the CSI on the physical channel and (ii) performing a separately encoding transmission on second part of information of the channel state information CSI on the physical channel, in response to the CSI transmitted on the physical channel including subband CSI; and transmitting the CSI, the first information, and the data information in the time slot in the multiplexing manner on the physical manner according to the determined transmission mode, wherein the first control information comprises at least one of: hybrid automatic retransmission request acknowledgement, HARQ-ACK, information or scheduling request, SR, information (S202). determining a transmission mode to satisfy a code rate upper limit configured by a base station, for transmitting channel state information, CSI, first control information, and data information in a time slot in a multiplexing manner of a plurality of multiplexing manners on a physical channel (S204), wherein the plurality of multiplexing manners comprises: (a) a first manner including performing a jointly encoding transmission on the first control information and all information of the CSI on the physical channel, in response to the CSI transmitted on the physical channel including at least one of wideband CSI or partial-band CSI; and (b) a second manner including (i) performing the jointly encoding transmission on the first control information and first part of information of the CSI on the physical channel and (ii) performing a separately encoding transmission on second part of information of the channel state information CSI on the physical channel, in response to the CSI transmitted on the physical channel including subband CSI; and (a) a first manner including performing a jointly encoding transmission on the first control information and all information of the CSI on the physical channel, in response to the CSI transmitted on the physical channel including at least one of wideband CSI or partial-band CSI; and (b) a second manner including (i) performing the jointly encoding transmission on the first control information and first part of information of the CSI on the physical channel and (ii) performing a separately encoding transmission on second part of information of the channel state information CSI on the physical channel, in response to the CSI transmitted on the physical channel including subband CSI; and transmitting the CSI, the first information, and the data information in the time slot in the multiplexing manner on the physical manner according to the determined transmission mode, wherein the first control information comprises at least one of: hybrid automatic retransmission request acknowledgement, HARQ-ACK, information or scheduling request, SR, information (S202). <EOS>
