Methods and apparatuses for using channel state information reference signals

摘要

In a wireless communication system, a wireless device is identified as being a relay device. A channel state information reference signal (CSI-RS) configuration is selected such that at least one CSI-RS can be transmitted to the wireless device in a subset of subframes assigned to relay backhaul transmissions.

1. A method for wireless communication, comprising: identifying a wireless device as being a relay device; and
selecting a channel state information reference signal (CSI-RS) configuration such that at least one CSI-RS is transmitted to the wireless device in a subset of subframes assigned to relay backhaul transmissions, the subset of subframes having resource blocks (RBs) that include resource elements (REs) assigned to an antenna port, and the CSI-RS configuration changing antenna port assignments for the at least one CSI-RS in at least a portion of the REs across the RBs in the subset of subframes to allow, and thereby enabling, power boosting of the at least one CSI-RS.
