    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: Enhanced sounding reference signal (SRS) transmissions for multiple input, multiple output (MIMO) operation are disclosed in which a user equipment (UE) detects an observed interference level for each receiver chain of the UE. In response to an imbalance, the UE precodes a SRS targeting downlink operation to indicate the imbalance. The UE then transmits the precoded SRS. In alternative aspects, the precoded SRS vector may be determined by an evolved nodeB (eNB). In such aspects, the eNB determines the precoded SRS vector targeting downlink operations for the served UEs, wherein the determined precoded SRS vector includes determining the precoded SRS vector on a per UE basis, enabling the precoded SRS vector for either one or both of frequency division duplex (FDD) systems and time division duplex (TDD) systems, or enabling the precoded SRS vector for aperiodic SRS only. The eNB then transmits the determined precoded SRS vector to the UE.

    Abstract: Certain aspects of the present disclosure generally relate to resolving ambiguous user equipment (UE) capability signaling. According to certain aspects, a method for wireless communications by a UE is provided. The method generally includes determining capabilities of the UE to support at least one of multiple-input multiple-output (MIMO) or coordinated multipoint (CoMP) features on different operating frequency bands of a radio access network (RAN), signaling, to a base station (BS) of the RAN, a first combination of capabilities of the UE for a combination of bands, signaling, to the BS, a second combination of capabilities, different than the first combination of capabilities, for the combination of bands, and identifying, based on or more criteria, a particular combination of capabilities to be used to communicate with the BS. In certain aspects, the UE may identify the combination of capabilities to use by applying a deterministic rule.

    Abstract: Certain aspects of the present disclosure provide techniques for managing resources utilized for enhanced physical downlink control channel (PDCCH) transmissions. According to certain aspects, a method is provided for wireless communications which may be performed, for example, by a user equipment (UE). The method generally includes receiving signaling indicating a set of time and frequency resources in one or more subframes allocated for an enhanced physical downlink control channel (PDCCH), receiving a downlink transmission in a subframe, making a determination to monitor for the enhanced PDCCH in the subframe based on the signaling, and decoding the enhanced PDCCH transmitted using the set of time and frequency resources in the subframe, in response to the determination.

    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.
