METHOD AND APPARATUS FOR CONSTRAINED HOPPING OF DOWNLINK REFERENCE SIGNALS

摘要

Methods and apparatuses are provided that facilitate employing constrained frequency hopping of downlink reference signals. In an aspect, a method that facilitates evaluating reference signals received via a downlink in a wireless communication environment is disclosed which includes receiving a sequence of subframes transmitted by a base station, each of the subframes having resource elements used to carry reference signals according to a constrained cell-specific hopping pattern. The method also includes combining reference signals sent from common antennas at common frequency locations in the subframes and estimating a channel based upon an evaluation of the combined reference signals.
