METHOD AND APPARATUS FOR TRANSMITTING UPLINK CONTROL INFORMATION IN WIRELESS ACCESS SYSTEM

摘要

The present invention relates to a method for transmitting channel quality control information in a wireless access system, which supports a hybrid automatic repeat request (HARQ), by using two transmission blocks. The method, according to one embodiment of the present invention, comprises the steps of: a terminal receiving a physical downlink control channel (PDCCH) signal including downlink control information (DCI); calculating the number of encoding symbols required for transmitting the channel quality control information by using the DCI; and transmitting the channel quality control information through a physical uplink shared channel (PUSCH) on the basis of the number of the encoding symbols.

主权项

1. A method for transmitting only Uplink Control Information (UCI) without uplink data on a Physical Uplink Shared CHannel (PUSCH) in a wireless access system supporting Carrier Aggregation (CA), the method comprising;
receiving a Physical Downlink Control Channel (PDCCH) signal including Downlink Control Information (DCI) format 4 from a Base Station (BS); allocating resources for transmitting the UCI based on the DCI format 4; calculating the number of code symbols for transmitting the UCI; channel-encoding the UCI; and transmitting only the channel-encoded UCI without the uplink data on the PUSCH to the BS.
