Abstract:
A method for measuring a channel in a wireless communication system is provided. A terminal receives a first reference signal from a primary cell. The terminal receives a second reference signal from a secondary cell corresponding to the primary cell. The terminal measures a channel for the secondary cell on the basis of the second reference signal. A subframe in which the second reference signal is received is signaled from the primary cell.

Abstract:
A method of transmitting a Relay Physical Downlink Control Channel (R-PDCCH) at a base station in a wireless communication system. A set of Virtual Resource Blocks (VRBs) are assigned for the R-PDCCH to a downlink subframe. The downlink subframe is transmitted to a relay node. The set of VRBs is configured to be same, by higher layer, in a first slot and a second slot of the downlink subframe. If the set of VRBs for the R-PDCCH is assigned in the first slot of the downlink subframe, the R-PDCCH is configured to contain a downlink assignment. If the set of VRBs for the R-PDCCH is assigned in the second slot of the downlink subframe, the R-PDCCH is configured to contain an uplink grant.
Abstract:
A method for an eNB to transmit a downlink signal to a User Equipment (UE) is disclosed. The method includes transmitting information about a data transmission power within an OFDM symbol in a data region of a downlink subframe to the UE. The information about the data transmission power is determined according to a specific condition and the specific condition includes at least one of presence/absence of a Cell-specific Reference Signal (CRS) within the symbol and a modulation scheme or a Modulation and Coding Scheme (MCS) of the symbol. The downlink subframe is a Non-Zero Power Almost Blank Subframe (NZP ABS) in which signals are transmitted at a lower transmission power than a transmission power of a normal subframe on downlink.
