Abstract
Technology for a user equipment (UE) operable to adjust a receiver timing is disclosed. The UE can decode a plurality of channel-state information reference signals (CSI-RSs) received from a plurality of cooperating nodes, wherein the plurality of cooperating nodes are included in a coordination set of a Coordinated MultiPoint (CoMP) system. The UE can generate a plurality of received RS timings from the plurality of CSI-RSs, wherein the received RS timings represent timings from the plurality of cooperating nodes. The UE can determine a composite received RS timing from the plurality of received RS timings. The UE can adjust the receiver timing based on the composite received RS timing.
