Patent ID: 10764800

Abstract:
An access node configures a user equipment, UE, to perform mobility management measurements using at least a first subset of beam-formed reference signals and to perform radio link monitoring, RLM, using at least some of the first subset of beam-formed reference signals used for the mobility management measurements. The access node transmits, in a first downlink signal having a series of subframes, a beam-formed reference signal in each of a plurality of subframes, where the beam-formed reference signals are transmitted in fewer than all of the subframes of the downlink signal. The UE receives, in the beam-formed downlink signal, the beam-formed reference signal in each of the plurality of subframes. The UE performs mobility management measurements using at least a first subset of the received beam-formed reference signals and performs RLM using at least some of the first subset of beam-formed reference signals used for the mobility management measurements.
