Abstract
Official abstract text for this publication.
A method of transmitting channel state information from a user equipment in a wireless communication system is disclosed. In order to report the channel state information, the user equipment is able to additionally transmit noise plus interference variance information as well as spatial channel matrix or spatial channel covariance matrix. The spatial channel matrix or spatial channel covariance matrix and the noise plus interference variance information can include information on a prescribed number of subbands in best channel states and can include information on a wideband including a plurality of subbands. Moreover, the user equipment is able to transmit normalized spatial channel matrix or spatial channel covariance matrix and normalized noise plus interference variance information for accurate and efficient transmission of the channel state information.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for transmitting channel state information at a user equipment (UE) in a wireless communication system supporting a coordinated multi-point (CoMP) operation, the method comprising: transmitting at least spatial channel matrix information or spatial channel covariance matrix information to each of a plurality of base stations which perform the CoMP operation among neighbor base stations; and transmitting noise plus interference variance information…
