Method and apparatus of configuring sounding reference signal for coordinated multi-point transmission

摘要

The disclosure provides a method of configuring sounding reference signal (SRS) for coordinated multi-point (CoMP) transmission. The method may include: determining for a CoMP UE in the cell set B a first SRS resource orthogonal with SRS resources configured for other UEs in the cell set A by exchanging information among cells within the cell set B; transmitting to the CoMP UE SRS configuration information describing the first SRS resource. The disclosure also provides apparatuses for configuring SRS of CoMP transmission.

1. A method of configuring a sounding reference signal (SRS) for coordinated multi-point (CoMP) transmission, the method comprising:
receiving, by a first cell from a second cell, information identifying plural SRS resources available in the second cell for a CoMP user equipment (UE) in the second cell; determining, by the first cell, a first SRS resource, which is orthogonal to SRS resources allocated to UEs in the first cell, from among the plural SRS resources as SRS resource to be used by the CoMP UE, ; and transmitting, by the first cell to the second cell, information of the first SRS resource determined for the CoMP UE.
