Claim of US Patent No. 10,694,508

1. A method for transmitting uplink control information at an apparatus configured with a plurality of cells including a Primary Cell (PCell) and a Secondary Cell (SCell) in a wireless communication system, the method comprising:receiving at least a Physical Downlink Control CHannel (PDCCH) signal indicating Semi-Persistent Scheduling (SPS) release or a Physical Downlink Shared CHannel (PDSCH) signal with a corresponding PDCCH; and
transmitting reception response information about the at least the PDCCH signal indicating SPS release or the PDSCH signal with the corresponding PDCCH through a Physical Uplink Control CHannel (PUCCH) at a time configured for Scheduling Request (SR) transmission,
wherein based on a predetermined condition not being satisfied, the reception response information and SR information are multiplexed and transmitted using a first PUCCH resource for Hybrid Automatic Repeat request Acknowledgement (HARQ-ACK),
wherein based on (i) the predetermined condition being satisfied and (ii) there being a positive SR for the time configured for SR transmission, the reception response information is transmitted using a PUCCH resource for SR, and
wherein the predetermined condition includes any one of:
only a single PDSCH transmission that is scheduled by a PDCCH having a Downlink Assignment Index (DAI) initial value is present on the PCell; and
only a single PDCCH transmission only on the PCell that has the DAI initial value and indicates SPS release is present on the PCell.
