Abstract: Certain aspects of the present disclosure relate to methods and apparatus for measuring and mitigating interference. Such interference may include base station to base station (eNB to eNB) interference and/or UE to UE interference. A base station may determine a first subframe configuration for the base station and a second subframe configuration for one or more other base stations, wherein the first and second subframe configurations have different ratios of uplink to downlink portions. The base station may measure interference caused by the one or more other base stations based on reference signals transmitted in downlink portions of the second subframe configuration.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus determines an interference type between a time division duplex (TDD) configuration subframe of a serving cell and a corresponding TDD configuration subframe of a neighboring cell, and sets a transmit power for an apparatus in the serving cell based on the interference type. The apparatus in the serving cell may be a user equipment (UE), in which case the apparatus applies a set of uplink (UL) open loop power control parameters for the UE. The apparatus in the serving cell may be a base station (eNB), in which case a DL transmit power is set for the eNB. Depending on the interference type, the DL transmit power may be a fixed, full power DL transmission or an adjusted DL transmission.

Abstract: In aspects, methods and apparatus for utilizing a reconfiguration timer for updating TDD configuration are provided. Certain aspects of the present disclosure propose methods and apparatus for improving system performance while using adaptive uplink-downlink reconfiguration in a time division duplex (TDD) system. For certain aspects, a reconfiguration timer may be utilized along with a signaling scheme, in order to enjoy benefits of the adaptive uplink-downlink reconfiguration with minimum signaling overhead.
