METHOD AND DEVICE FOR TRANSMITTING AND RECEIVING CHANNEL STATE INFORMATION IN WIRELESS COMMUNICATION SYSTEM

摘要

The present invention relates to a wireless communication system. A method by which a user equipment reports a channel state information (CSI) in a wireless communication system, according to one embodiment of the present invention, can comprise the steps of: setting up a first CSI process in which a subframe pattern for a first subframe set, which uses an almost blank subframe (ABS), and a second subframe set, which does not use the ABS, is set; setting up a second CSI process in which the subframe pattern is not set; setting a second rank indicator (RI) of the second CSI process to be the same as a first RI corresponding to the second subframe set when the second CSI process is established so as to have the same RI as the first CSI process; and transmitting the CSI on the basis of the first CSI process and/or the second CSI process.

主权项

1. A method of reporting channel state information (CSI) in a wireless communication system, the method performed by a user equipment and comprising:
configuring a first CSI process, in which subframe patterns for a first subframe set based on an almost blank subframe (ABS) and a second subframe set which is not based on the ABS are configured; configuring a second CSI process in which the subframe patterns are not configured; configuring a second rank indicator (RI) of the second CSI process to be the same as a first RI corresponding to the second subframe set when the second CSI process is configured to have the same RI as that of the first CSI process; and transmitting the CSI on the basis of at least one of the first CSI process and the second CSI process.
