Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in which a cell identifier is selected based on one or more properties associated with received downlink control information (DCI), where the properties may not be exclusively associated with determining a cell identifier. The cell identifier may be selected from a plurality of cell identifiers received through radio resource control signaling. The properties of the DCI may include a type of download control channel, a type of subframe and a type of DCI format used to provide the DCI.

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: Techniques for reporting channel state information (CSI) based on scalable channel feedback are described. A user equipment (UE) may receive data transmission from one or more cells among a plurality of cells and may report CSI for each of the plurality of cells. For scalable channel feedback, the UE may report CSI with different granularity for different cells. The granularity of feedback for each cell may be selected based on the quality of a communication channel between the cell and the UE, which may be determined based on a long-term channel gain for the cell. The granularity of feedback may be defined by a subband size, a reporting interval, granularity of quantization of CSI, etc. The UE may report CSI for each cell based on the granularity of feedback for the cell. The UE may receive data transmission sent by at least one cell based on the reported CSI.

Abstract: Methods and apparatus are provided for assigning interference measurement resources. A method includes receiving at least one identifier, which determines, at least in part, at least one interference measurement resource that partially overlaps with another at least one interference measurement resource. The at least one interference measurement resource comprises a number of resource elements out of a set of resource elements. The method also includes measuring interference based at least in part on the at least one interference measurement resource.

Abstract: Certain aspects provide methods and apparatus for wireless communications. One example method generally includes receiving a shared channel within a subframe, determining the same precoding may be used across resource blocks belonging to the same precoding resource block group (PRG) of the shared channel, and processing the shared channel based on the determination.

Abstract: Certain aspects provide methods and apparatus for processing a control channel and/or a shared channel in a subframe based on a determination that one or more channel properties of the two channels are substantially the same. One example method generally includes receiving a control channel and a shared channel within a subframe; determining that one or more channel properties of the control channel and the shared channel in the subframe are substantially the same; and processing the control channel and the shared channel based on the determination. In this manner, estimations determined for a first channel may be assumed for a second channel whose channel properties are substantially the same as the first channel, rather than by separately determining the estimations for the second channel, thereby saving processing time.

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: 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, an apparatus, and a computer program product for wireless communication are provided. In an aspect, the apparatus may determine whether a starting symbol of an enhanced physical downlink control channel (EPDCCH) is an initial symbol in a subframe based on an EPDCCH configuration. Based on the determination, the apparatus may refrain from decoding a subset of legacy control channels in the subframe when the starting symbol of the EPDCCH is the initial symbol in the subframe. The legacy control channel may comprise at least one of a physical control format indicator channel (PCFICH), a physical hybrid-ARQ indicator channel (PHICH), or a combination thereof.

Abstract: Certain aspects of the present disclosure provide techniques for implicitly linking aperiodic channel state information (A-CSI) reports to CSI-reference signal (CSI-RS) resources. In an aspect, the UE may be instructed to report on specific CSI-RS resource(s) via explicit signaling in the UE grant. Other aspects disclose techniques for implicit CSI-RS resource selection by the UE that require fewer signaling resources. Instead of explicitly signaling CSI-RS resources to the UE, the UE may implicitly select CSI-RS resource for CSI feedback reporting based on information known to the UE, e.g. a subframe on which a reporting request is received. This may reduce the impact of the additional signaling in the UE grant.

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.
