Abstract: Certain aspects of the present disclosure provide methods and apparatus for joint support of coordinated multipoint (CoMP) operations and carrier aggregation (CA). One method generally includes receiving signaling indicating a configuration, from a set of possible configurations, that defines how the UE is to communicate with one or more base stations (BSs) using coordinated multipoint (CoMP) operations on one or more component carriers (CCs) and communicating in accordance with the configuration.

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.

Abstract: A method of wireless communication includes determining a capability for a number of channel state information configurations supported by a user equipment (UE). The channel state information processes link a channel measurement report with an interference measurement report. The UE transmits the capability to an eNodeB. Additionally, the UE receives CSI process configurations. The CSI process configurations identify CSI processes that can be requested by the eNodeB.

Abstract: A method for providing multi-hypothesis channel quality indicator (MH-CQI) feedback is described. Hypotheses corresponding to rank indicator (RI) and precoding matrix indicator (PMI) assumptions associated with a dominant interferer are selected. Multi-hypothesis channel quality indicator (MH-CQI) values based on the selected hypotheses are generated. The multi-hypothesis channel quality indicator (MH-CQI) values are encoded. The multi-hypothesis channel quality indicator (MH-CQI) values are sent as feedback.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. In an aspect, the apparatus may configure at least a first resource set and a second resource set for a control channel. The first and second resource sets may be configured with a common reference signal configuration. The apparatus also configures first rate-matching parameters for the first resource set and second rate-matching parameters for the second resource set. Then, the apparatus transmits the first rate-matching parameters and the second rate-matching parameters and transmits the control channel using the first resource set and the second resource set.

Abstract: Determination of channel state information (CSI) feedback by mobile devices is disclosed in which the mobile device receives one or more configuration parameters, that may include one or more control channel parameters for configuring a mobile device control channel. The UE uses the configuration parameters to determine an assumption of overhead resources. Using this overhead assumption, the mobile device derives the CSI index and transmits the CSI index to a serving base station.
