    摘要： Methods and apparatus for partitioning resources for enhanced inter-cell interference coordination (eICIC) are provided. Certain aspects involve broadcasting a message indicating time-domain resource partitioning information (RPI), where a user equipment (UE) may be operating in idle mode. With the RPI, the UE may be able to identify protected resources with reduced/eliminated interference from neighboring cells. The RPI in this broadcasted message may be encoded as a bitmap as an alternative or in addition to enumeration of the U/N/X subframes. Other aspects entail transmitting a dedicated or unicast message indicating the time-domain RPI, where a UE may be operating in connected mode. With the RPI, the UE may be able to determine channel state information (CSI), make radio resource management (RRM) measurements, or perform radio link monitoring (RLM), based on one or more signals from a serving base station during the protected time-domain resources.

    摘要： Communication in a dominant interference scenario may be supported by performing inter-cell interference coordination (ICIC). Resource coordination/partitioning may be performed to allocate resources to a serving Node B located near the vicinity of a strong interfering Node B. The interfering Node B may avoid transmitting on the allocated/protected resources, possibly except for a common reference signal (CRS). A UE can then communicate with the serving Node B on the protected resources in the presence of the interfering Node B and may observe no interference (possibly except for the CRS) from the interfering Node B. When CRS tones of an interferer may collide with control/data tones of a serving cell, CRS interference cancellation (CRS IC) or puncturing of interfered resource elements (REs) may be appropriate. Certain aspects of the present disclosure provide techniques, where the UE may dynamically switch between CRS IC and RE puncturing based on certain parameters.

    摘要： In a wireless communication system, interference on data tones is estimated by detecting data transmissions from interferers. An overall interference covariance matrix is estimated as a function of scalar traffic to pilot ratio (TPR) estimates, residual interference covariance estimates, and covariance of channel estimates of dominant interferers. The interference estimates are refined as a function of reliability based on a ratio of power received from a serving cell and power received from a dominant interferer.
