Claim of US Patent No. 10,772,096

1. An Uplink Control Information (UCI) transmission method, comprising:when a collision is present between different types of UCIs with a first Transmission Time Interval (TTI) length and/or a collision is present between a UCI with the first TTI length and a UCI with a second TTI length,
transmitting the UCIs with the collision to a base station simultaneously using a second shortened Physical Uplink Control CHannel (sPUCCH) format on a predetermined sPUCCH resource corresponding to the second sPUCCH format, wherein the second sPUCCH format is a sPUCCH format with a maximum payload capacity greater than or equal to a predetermined bit value, and the predetermined sPUCCH resource corresponding to the second sPUCCH format is an additional sPUCCH resource other than a sPUCCH resource adopted by the UCIs with the collision; or
determining a transmission scheme for the UCIs with the collision in accordance with a sPUCCH format adopted by the UCI with the first TTI length,
wherein the determining the transmission scheme for the UCIs with the collision in accordance with the sPUCCH format adopted by the UCI with the first TTI length comprises:
when a first sPUCCH format is adopted by the UCI with the first TTI length, transmitting the UCIs with the collision to the base station simultaneously using a second sPUCCH format on the predetermined sPUCCH resource corresponding to the second sPUCCH format; or
when the second sPUCCH format is adopted by the UCI with the first TTI length, transmitting the UCIs with the collision to the base station simultaneously using a second sPUCCH format on the sPUCCH resource corresponding to the second sPUCCH format, wherein the sPUCCH resource corresponds to the UCI with the first TTI length,
wherein the first sPUCCH format is a sPUCCH format with a maximum payload capacity smaller than the predetermined bit value, and the second sPUCCH format is a sPUCCH format with a maximum payload capacity greater than or equal to the predetermined bit value.
