User terminal and radio communication method

(c2) The UE may transmit both the P-CSIs and the SR in the PUCCH if PF4 or 5 is used in P-CSI transmission, or, otherwise, the UE drops all the P-CSIs and transmits the SR alone in the sPUCCH. Note that, if the SR is transmitted in the PUCCH, the SR is one bit and located before or after the P-CSIs. In the case where the P-CSIs and the SR are both transmitted in PF4 or 5, it may be possible to compare the coding rate, which is derived from the total payload of the P-CSIs and the SR and the amount of radio resources in PF 4 or 5, with a value configured by higher layer signaling (predetermined value), and drop one or a plurality of P-CSIs so as to make the above coding rate equal to or lower than the predetermined value.
If the UE cannot transmit the PUCCH and sPUCCH simultaneously, the UE can transmit one or a plurality of P-CSIs that were originally intended to be transmitted in the sPUCCH and the SR that is originally scheduled to be transmitted in the PUCCH in accordance with one of following (d1) to (d3):
(d1) The UE may drop all of the P-CSIs and may transmit only the SR in PUCCH;
(d2) The UE may drop all of the P-CSIs and transmit only the SR in sPUCCH; and
(d3) The UE may transmit both the P-CSIs and the SR in the sPUCCH.
Note that the SR is one bit, and located before or after the P-CSIs. When both P-CSIs and the SR are transmitted in the sPUCCH, it may be possible to compare the coding rate, which is derived from the total payload of the P-CSIs and the SR and the amount of radio resources in the sPUCCH, with a value configured by higher layer signaling (predetermined value), and drop one or a plurality of P-CSIs so as to make the above coding rate equal to or lower than the predetermined value.
