Abstract

Provided is a method for transmitting channel quality control information using two transport blocks in a wireless access system that supports hybrid automatic retransmit request (HARQ). The method may include the steps of receiving a physical downlink control channel (PDCCH) signal including downlink control information (DCI); calculating the number of coded symbols, Q', required to transmit the channel quality control information using the DCI; and transmitting the channel quality control information through a physical uplink shared channel (PUSCH) on the basis of the number of coded symbols.

Description

technical field [0001] The present invention relates to wireless access systems, and more particularly, to a method and apparatus for transmitting uplink channel information (UCI) including channel quality control information in a carrier aggregation environment (ie, a multi-component carrier environment). The present invention relates to a method and a device for obtaining the number of resource elements allocated for UCI when the UCI is attached to a physical uplink shared channel (PUSCH). Background technique [0002] The 3GPP LTE (3rd Generation Partnership Project Long Term Evolution; Rel-8 or Rel-9) system (hereinafter referred to as the LTE system) employs multicarrier modulation (MCM) that divides a single component carrier (CC) into multiple frequency bands And use the plurality of frequency bands. However, the 3PP LTE-Advanced system (hereinafter referred to as LTE-A system) may use carrier aggregation (CA), which aggregates one or more CCs to support a wider syst...
