Abstract

A reference signal (RS) transmission system to transmit a channel state information (CSI) RS for extraction of CSI to a relay and a macro terminal is disclosed. The base station transmits information on a sub frame containing the CSI RS to the relay or the macro terminal. The macro terminal and the relay receive the CSI RS using the information on the sub frame. The macro terminal and the relay extract the CSI using the CSI RS and transmit the extracted CSI to the base station.

Claims6

Dependent claims

A method for wireless communication, comprising:

receiving,
by a user equipment (UE), information on reception of a plurality of Channel State Information Reference Signals (CSI-RSs), wherein the information includes at least one parameter to determine candidate subframes;
receiving, by the UE, information indicating locations of first subframes that satisfy a first condition;
and
receiving, by the UE, the plurality of CSI-RSs using a first set of the candidate subframes that do not satisfy any of one or more predetermined conditions including the first condition,
wherein a second set of the candidate subframes, including the first subframes, that satisfy any of the one or more predetermined conditions, including the first condition, are not used to receive the plurality of CSI-RSs by the UE.
