Apparatus for transmitting an uplink signal and method thereof

摘要

An apparatus for transmitting an uplink signal and method thereof are disclosed, by which an uplink signal can be efficiently transmitted in a wireless communication system. The present invention includes receiving a downlink control information (DCI) used for PUSCH (physical uplink shared channel) scheduling, the DCI including an information for resource block allocation, an information for a channel status information request and a plurality of MCS (modulation and coding scheme) informations for a plurality of transport blocks and if a condition is met, transmitting a channel status information only on the PUSCH without a transport block for UL-SCH (uplink shared channel). Moreover, the condition includes a case that: only one transport block is enabled, the MCS information for the enabled transport block indicates an MCS index 29, the information for the channel status information request indicates 1, and the number of allocated resource blocks is equal to or smaller than 4.

1. A method of transmitting an uplink signal from a user equipment in a wireless communication system, the method comprising:
receiving a downlink control information (DCI) used for PUSCH (physical uplink shared channel) scheduling, the DCI including information for resource block allocation, information for a channel status information request and a plurality of MCS (modulation and coding scheme) information for a plurality of transport blocks; and if a condition is met, transmitting channel status information only on the PUSCH without any of the plurality of transport blocks, wherein the condition includes:
only one transport blocks being enabled,the MCS information only for the enabled transport block indicating an MCS index 29,the information for the channel status information request being set to trigger the transmission of the channel status information, andthe number of allocated resource blocks being equal to or smaller than 4.
