Abstract: A method for mitigating interference in a wireless network includes an eNodeB and/or a UE identifying interference. The eNodeB may identify the interfering TDD configurations based on a downlink signal of a neighboring eNodeB received during an uplink timeslot for a UE associated with the eNodeB. Likewise, the UE may identify an interfering UE based on an uplink signal received during a downlink timeslot for an eNodeB associated with the UE. The eNodeB performs interference management based at least in part on the identified interference. HARQ transmissions are rescheduled from non-anchor subframe potentially not common to a set of TDD configurations to anchor subframe common to the set of TDD configurations.

Abstract: Se proporcionan un método, un aparato y un producto de programa de computadora para la comunicación inalámbrica. En un aspecto, el aparato puede recibir un conjunto de configuraciones para un EPDCCH que están ligadas a un conjunto de configuraciones recibidas para un PDSCH. El aparato puede recibir y procesar entonces el EPDCCH en base a al menos una configuración del conjunto de configuraciones para el EPDCCH. En otro aspecto, el aparato puede determinar al menos un primer y un segundo conjunto de recursos configurado para un canal de control y puede determinar un conjunto común de niveles de agregación para el primer y el segundo conjunto de recursos. El aparato también puede determinar los primeros parámetros de la misma velocidad de transmisión para el primer conjunto de recursos y los segundos parámetros de la misma velocidad de transmisión para el segundo conjunto de recursos y puede procesar el canal de control usando el conjunto común de niveles de agregación y los primeros y los segundos parámetros de la misma velocidad de transmisión.

Abstract: Techniques for performing path loss (PL) compensation in coordinated multipoint (CoMP) systems are provided. A method for wireless communications by a user equipment (UE) is provided. The method generally includes selecting from a plurality of transmission points involved in uplink (UL) coordinated multipoint (CoMP) operations with the UE a transmission point to associate with for path loss (PL) compensation and adjusting power of one or more transmissions based on path loss measured based on the selected transmission point.

Abstract: Aspects of the present disclosure relate generally to wireless communication systems and more particularly to defining a structure of and enhanced physical downlink control channel (e PDCCH). Certain aspects provide methods and apparatus for determining a search space in which a base station (eNodeB) may transmit an enhanced physical downlink control channel (e PDCCH) wherein the search space comprises one or more fractional portions of frequency time resources of a physical resource block (PRB) pair and attempting to decode the e PDCCH based on the determined search space.

Abstract: A method (800) for wireless communication is provided which includes receiving first and second signals transmitted from first and second antennas respectively (802) determining a time offset between the first and second antennas based on the first and second signals (804) and reporting information regarding the time offset including information regarding the time offset as being above or below a predetermined threshold (806). Another method (900) for wireless communication is provided which includes generating channel state information feedback based on an assumption that the time offset is being compensated at a transmitter side. Yet another method (1000) for wireless communication is provided which includes receiving information regarding a time offset between multiple transmit antennas including information regarding the time offset as being above or below a predetermined threshold (1002) and adapting downlink transmissions to account for the time offset (1004).
