摘要

an access node transmits, in a downlink signal having a series of subframes, a subframed beam reference signal, wherein the beamformed reference signals are transmitted in less than all subframes of the subframed signal. downlink. a first subset includes the formed beam reference signals corresponding to a first frequency or first localized frequency range, and a second subset includes the formed beam reference signals corresponding to a second frequency or second localized frequency range. the second or second localized frequency range is spaced and differs from the first or first localized frequency range. a user equipment, which receives, in the downlink signal, the beam reference signal formed in each of a plurality of subframes. which performs mobility management measurements using at least the first subset of the received formed beam reference signals and performs the rmm using the second subset of the received beamformed reference signals.
