Abstract
Official abstract text for this publication.
A method and an apparatus for receiving downlink data in a multi-carrier system are provided. A terminal receives a downlink grant on a physical downlink control channel (PDCCH) via a first component carrier, and determines a transmission power of a physical downlink shared channel (PDSCH) depending on whether a control channel exists in each orthogonal frequency division multiplexing (OFDM) symbol of a subframe of a second component carrier that is indicated by the downlink grant. Based on the transmission power of the PDSCH, the terminal receives downlink data on the PDSCH indicated by the downlink grant via the second component carrier. When a control channel and a data channel coexist in the same OFDM symbol, the reliability of receiving the control channel can be increased.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of receiving downlink data in a multi-carrier system, performed by a user equipment, the method comprising: receiving a downlink grant on a first physical downlink control channel (PDCCH) via a first component carrier from a base station, wherein the downlink grant includes a carrier index indicating a second component carrier in which a second PDCCH is not transmitted; determining how an amount of power a physical downlink shared channel (P…
