Abstract

The present invention relates to a method and a device by which a user equipment monitors a downlink control channel in a wireless communication system. More specifically, the method comprises a step of monitoring the downlink control channel on a flexible downlink subframe, wherein the flexible downlink subframe is obtained by reconfiguring, for downlink communication, an uplink subframe configured according to a reference UL-DL configuration, the reference UL-DL configuration is configured by the combination of a first UL-DL configuration set for a first cell and a second UL-DL configuration set for a second cell, and the first UL-DL configuration and the second UL-DL configuration are configured so as to change the usage of wireless resources.

Dependent claims

A method of monitoring a downlink control channel of a user equipment (UE) in a wireless communication system, the method comprising:

receiving a configuration related to a channel state information (CSI) measurement;
and
monitoring the downlink control channel on a specific subframe set of several subframe sets based on parameters for physical downlink shared channel (PDSCH) resource element mapping received via higher layer signaling,
wherein the parameters include one or more zero power channel state information reference signal (CSI-RS) configurations, when the received configuration indicates several subframe sets in which different CSI measurements are each to be performed for one serving cell.
