Abstract  Abstract

claims for the coordinated multi-point (CoMP) system technology for adjusting receiver timing of the wireless device. A method can comprising a plurality of cooperative node in a wireless device from the coordination set in CoMP system receiving a plurality of node specific reference signal (RS). coordination group comprises at least two cooperating node. the wireless device may estimate the synthesized reception from a plurality of received RS timing RS timing multiple receiving timing specific RS generated from the plurality of nodes. receiving RS timing represents a timing of the at least two cooperative node. wireless device may be based on a synthesized reception RS timing adjustment receiver timing. node-specific RS may include a channel state information reference signal (CSI-RS).

Technology for adjusting a receiver timing of a wireless device in a Coordinated Multipoint (CoMP) system is disclosed. One method can include the wireless device receiving a plurality of node specific reference signals (RSs) from a plurality of cooperating nodes in a coordination set of the CoMP system. The coordination set includes at least two cooperating nodes. The wireless device can estimate a composite received RS timing from a plurality of received RS timings generated from the plurality of node specific RSs. The received RS timings represent timings from the at least two cooperating nodes. The wireless device can adjust the receiver timing based on the composite received RS timing. A node specific RS can include a channel-state information reference signal (CSI-RS).
