Abstract:
The present specification relates to a wireless communication system and, more particularly, to a method for reporting a channel state and an apparatus therefor. When a plurality of channel state information-reference signal (CSI-RS) resources are set for a channel state information (CSI) process, a terminal of the present invention generates channel state information indicating a CSI-RS resource indicator (CRI) indicating one of the plurality of CSI-RS resources and a rank indicator (RI) which is based on the CRI. The terminal reports the channel state information. Accordingly, the present invention is capable of more efficient channel state reporting by transmitting a CRI indicating a CSI-RS resource, selected from among a plurality of CSI-RS resources set for the CSI process, together with the RI for the selected CSI-RS resource.

Claim (Index 5):
The method according to  claim 4 , wherein the channel state information including the CRI and RI based on the CRI or channel state information including RI for the single CSI-RS resource without CRI indicating the single CSI-RS resource is transmitted through resource elements obtained as much as the number based on the following Equation: Q \u2032 = min ( \u2308 O \u00d7 M sc PUSCH \ue89e - \ue89e initial \u00d7 N symb PUSCH \ue89e - \ue89e initial \u00d7 \u03b2 offset \u2211 r = 0 C - 1 \ue89e K r \u2309 , 4 \u00d7 M sc PUSCH ) , where O indicates a total number of bits including the CRI and RI based on the CRI, which will be transmitted, or a total number of bits of RI for the single CSI-RS resource, M sc PUSCH  indicates the number of subcarriers allocated for PUSCH (physical uplink shared channel) transmission, M sc PUSCH-initli  indicates the number of subcarriers allocated at a subframe of an initial PUSCH transmission timing, N symb PUSCH-initial  indicates the number of SC-FDMA (single carrier-frequency division multiple access) symbols used for PUSCH transmission at the subframe of the initial PUSCH transmission timing, C and K r  indicate the number of coding blocks of data which will be transmitted through the PUSCH and a length of data bits per code blocks, and \u03b2 offset  indicates an offset value or corrected value.
