    Abstract: Methods, systems, and apparatuses are described for wireless communications. In one method, an uplink grant may be received over a licensed spectrum. A clear channel assessment (CCA) may be performed in response to the uplink grant to determine availability of an unlicensed spectrum. The CCA may be performed prior to a transmission associated with the uplink grant. In another method, scheduling information may be received over a licensed spectrum. An uplink grant may be transmitted over the licensed spectrum. The uplink grant may be based at least in part on the scheduling information. The uplink grant may be configured to trigger a CCA to determine availability of an unlicensed spectrum prior to a transmission associated with the uplink grant.

    Abstract: Collision handling of channel state information (CSI) reports is described for enhanced inter-cell interference coordination (elCIC), coordinated multipoint transmission (CoMP), and/or carrier aggregation (CA). Various aspects include prioritization schemes to resolve collisions between different CSI reporting sets in relation to the same component carrier (CC) used with transmission. Multiple stages of prioritization may identify CSI for a report based on various criteria. Tie breaker criteria may be defined for priority among CSI reports that changes for different subframes. In other aspects, PUSCH is utilized to transmit CSI for prioritized reporting sets in a subframe. In yet other aspects, if parallel PUCCH is supported, colliding CSI may be handled on a per PUCCH basis. Other aspects may allow for prioritizing periodic CSI within each of multiple CCs, and then prioritizing over different CCs to handle an interaction of CSI reports for CA, elCIC and/or CoMP.

    Abstract: In macro/RRH setups, channel state information reference signals (CSI-RS) and demodulation reference signals (DM-RS) may be used to decouple control and data transmission. Data transmission (e.g. for LTE Rel 10 and beyond) may be based on CSI-RS and DM-RS, while control may be received from a different set of cells or TxPs via CRS. Certain aspects of the present disclosure introduce a reporting framework, in which configuration of data-serving cells/TxPs may be carried out based on CSI-RS. In certain aspects, a new concept of CSI-RS groups, i.e., a set of CSI-RS ports that a UE considers as one group for precoding matrix indicator (PMI)/channel quality indicator (CQI)/rank indicator (RI) reporting, may be defined.

    Abstract: Techniques for sending control information relating to multiple downlink carriers and data on a single uplink carrier are described. A user equipment (UE) may be scheduled to transmit on a designated uplink carrier. The UE can multiplex control information for multiple downlink carriers with data for transmission on the uplink carrier in a same sub frame. Multiplexing may be performed according to a type of the control information and/or an ordering, priority, or association of the downlink carriers. The UE can selectively encode the control information separately for each downlink carrier and/or jointly across downlink carriers. The control information may be mapped to a single layer or multiple layers of a data channel. The UE may send the multiplexed control information and data on the data channel in the subframe while maintaining a single-carrier waveform.

    Abstract: Methods, apparatuses, and articles of manufacture are disclosed for adjusting a power level in connection with transmitting parallel uplink channels. In one aspect, a user equipment determines a power-limited condition in which a total transmit power of a group of power-controlled channels exceeds a maximum level in a transmission subframe. The user equipment may determine, in an iterative fashion, power backoff values by which to establish a configured maximum power level. The parallel uplink channels in the group may be prioritized and different backoff values may be used with channels having different priorities. The user equipment may thereafter adjust a transmit power of the power-controlled channels based on the configured maximum power level.
