Resource partitioning information for enhanced interference coordination
First Claim
1. A method for wireless communications, comprising:
- transmitting an indication of time domain resource partitioning information (RPI), the RPI identifying one or more protected subframes, the one or more protected subframes being subframes in which use by an interfering access point is limited, wherein the one or more protected subframes correspond to one or more almost blank subframes (ABS) associated with the interfering access point, and wherein the indication of the time domain RPI is transmitted using a dedicated message or a unicast message; and
receiving a report, from a user equipment (UE), indicating radio conditions measured during the protected subframes.

Abstract
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.
