Abstract:
1. A method for transmitting uplink control information by a user equipment (UE) configured with a plurality of serving cells including a primary cell and a secondary cell in a wireless communication system, the method comprising: receiving, by the UE from a base station (BS), information through an Semi-Persistent Scheduling (SPS) activation Physical Downlink Control Channel (PDCCH), the information indicating at least one Physical Uplink Control Channel (PUCCH) resource of a first set of PUCCH resources having been configured by an RRC (Radio Resource Control) layer and corresponding to a predefined PUCCH format; after receiving the SPS activation PDCCH, receiving, by the UE from the BS, an SPS Physical Downlink Shared Channel (PDSCH) via the primary cell without receiving a corresponding PDCCH in the primary cell, the SPS PDSCH including only one transport block when the primary cell is set to a first transmission mode supporting a transmission of only a single transport block via the SPS PDSCH, the SPS PDSCH including up to two transport blocks when the primary cell is set to a second transmission mode supporting a transmission of up to two transport blocks via the SPS PDSCH; generating, by the UE, a Hybrid Automatic Repeat reQuest-Acknowledgement (HARQ-ACK) response corresponding to the SPS PDSCH received via the primary cell; one of:
