SYNCHRONIZATION OF TIME CHARACTERISTICS FOR DOWNLINK (DL) TRANSMISSION IN COORDINATED MULTI-POINT (COMP) SYSTEMS Russian patent published in 2017 - IPC H04J11/00 

FIELD: wireless communication equipment.

SUBSTANCE: invention relates to communication engineering and can be used in wireless communication systems. For this, invention discloses wireless device receiver timing adjusting technology in coordinated multi-point (CoMP) system. Method includes receiving plurality of node-specific reference signals (RS) in UE from plurality of nodes in CoMP system coordination set, wherein coordination set includes, at least, two nodes; generating plurality of node-specific RS time characteristics received by antenna ports for, at least, two nodes; estimating average time delay from plurality of received RS time characteristics, wherein average time delay includes transmitter (TX) delay, delay on distribution, receiver (RX) delay or other delay for processing; and adjusting received UE time characteristics, at least, partially, based on average time delay.

EFFECT: technical result is improvement of reliability of communication.
