Method and apparatus for transmitting control information

摘要

The present invention relates to a wireless communication system. More particularly, the present invention relates to a method and apparatus for transmitting uplink control information in the event of a plurality of cell, wherein the method comprises the following steps: receiving a PDCCH and/or a PDSCH; generating reception acknowledgement information for said PDCCH and/or PDSCH; and transmitting the reception acknowledgement information in an SR subframe via a PUCCH.

1. A method for transmitting uplink control information at a communication device configured with plural cells in a wireless communication system, the method comprising:
receiving, by the communication device, a plurality of data blocks for each cell of the plural cells, the plural cells including aprimary cell (PCell) and a secondary cell (SCell); generating, by the communication device, reception response information in response to the received data blocks; and transmitting, by the communication device, the reception response information throughusing a physical uplink control channel (PUCCH) resource, wherein, for a positive scheduling request (SR), the reception response information is bundled for each cell of the plural cells and mapped to a first bit b(0) and a second bit b(1), and the PUCCH resource is a predetermined SR PUCCH resource, wherein the first bit b(0) represents a bundled hybrid automatic repeat request acknowledgement (HARQ-ACK) bit for the PCell and the second bit b(1) represents a bundled HARQ-ACK bit for the SCell, and wherein, for a negative SR, the PUCCH resource is a HARQ-ACK PUCCH resource.
