Interference mitigation in the context of heterogeneous networks with coordinated transmission points with a common transmission point identity

摘要

Technology is discussed for extending frequency and time based approaches, such as Inter-Cell Interference Coordination (ICIC) and enhanced ICIC (eICIC), to interference mitigation for clusters within a Wireless Wide Area Network (WWAN) of transmission points with a common transmission point identity. Multiple transmission power messages correlated to different transmission point characteristics can be configured among multiple transmission points sharing the same transmission point identity. These multiple transmission power messages can be used to coordinate transmissions from adjacent transmission points on differing frequencies. Additionally, new sets of reference signals can be configured to correlate to different transmission point characteristics. These new, correlated reference signals can be used to decouple measurements used to provide feedback to one set of transmission points from reference signals transmitted by another set of transmission points with the same transmission point identity.
