Abstract: Methods, systems, and devices are described for wireless communication in a system that supports enhanced carrier aggregation (eCA). An eCA configuration with a large number of component carriers (CCs) may include CCs grouped into channel state information (CSI) reporting groups. Channel state reports for the CCs in each group may be reported together. In some cases, individual CC reports may be multiplexed into a single report, and in other cases a single channel state report may contain information related to each CC in the group. The combined reports may be transmitted over an uplink control channel or an uplink data channel, or both. Collisions between reports may be resolved based on the reporting type of the groups or the serving cell indices of the CCs in the group.

Abstract: Certain aspects of the present disclosure relate to procedures for aggregation in dual connectivity. In one aspect, a wireless device may receive configuration information to communicate with a first network entity (e.g., master eNodeB) through a first primary cell (PCell) of a corresponding group of cells of the first network entity, and with a second network entity (e.g., secondary eNodeB) through a second primary cell (PCellSCG) of a corresponding group of cells of the second network entity. The second network entity may be non-collocated with the first network entity. The wireless device may include an information convergence entity (e.g., PDCP entity) that aggregates the configuration information from the first and second network entities when the wireless device is in communication with both entities. In another aspect, the second network entity may have one of the cells in the corresponding group of cells operate as the second primary cell.

Abstract: Aspects of the present disclosure relate to techniques for determining timing of uplink transmissions for UEs communicating with carrier aggregation involving both frequency division duplexing (FDD) and time division duplexing (TDD) component carriers (CCs). A timing advance (TA) offset value for a user equipment (UE) to use for uplink transmissions is determined based, at least in part, on which of the CCs carries a physical uplink control channel (PUCCH).

Abstract: Techniques are provided for aggregating carriers with different carrier configurations. The carriers may include both time division duplex (TDD) and frequency division duplex (FDD) carriers which may be configured such that control information for both carrier types is conveyed by the TDD carrier. In one aspect, an association between a set of subframes, including both TDD and FDD subframes, is determined. The association may operate to distribute control information for the FDD carrier over uplink subframes of the TDD carrier to achieve a load balancing. Alternatively, the association may operate to minimize a hybrid automatic repeat request (HARQ) feedback delay. The TDD carrier may provide resource grants for the aggregated carriers and the association may be used to identify subframes from both carriers which may be scheduled in a given DL subframe.

Abstract: Techniques for improving uplink throughput of UE uplink transmissions are disclosed. The UE may communicate with an eNB over an LTE wireless link using a first radio, and with a WLAN access point over a WLAN wireless link using a second radio. The UE may schedule a first portion of uplink data from an aggregating layer of the UE for transmission over the WLAN wireless link during a scheduling window, the scheduling based on an availability of access to the LTE wireless link. The UE may transmit the first portion of the uplink data over the WLAN wireless link during the scheduling window. The aggregation of the LTE wireless link with the WLAN wireless link may allow the UE to transmit uplink data from the aggregating layer of the UE over both the LTE wireless link or the WLAN wireless link.

Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) may coordinate power utilization across component carriers (CCs) with different transmission time interval (TTI) configurations. For example, the UE may reserve a portion of the transmit power for a CC with a reduced TTI length (e.g., an enhanced CC (eCC)). In other examples, the UE may dynamically allocate power between CCs with overlapping uplink periods. That is, the UE may borrow power allocated to one CC to transmit on an eCC. The UE may use a prioritization scheme to determine the transmit power for each CC. In some cases, the UE may send a power headroom report based on the power level of the eCC. The power headroom may be a virtual power headroom based on predicted eCC transmission power, or an actual power headroom based on uplink scheduling.

Abstract: Methods, systems, and apparatuses for enabling and utilizing variable length transmission time intervals (TTI) are described. Latency for communications between base stations and user equipment (UEs) may be reduced by flexibly and dynamically adapting to data traffic needs. TTI for a given UE may be dynamically adjusted according to UE or system requirements and the configuration of uplink and downlink TTI. A base station may utilize dynamic grants to schedule resources within a system. A UE may receive a grant in a first portion of a variable TTI. The UE may determine a duration of the variable TTI based on the grant, and the UE may communicate accordingly. The UE may receive a subsequent grant in the variable TTI—either in the first portion or another portion—and may respond or alter its operation accordingly.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided in connection with specifying a traffic-to-pilot (T/P) ratio per subframe and/or resource block to allow a base station to transmit over the subframes and/or resource blocks using varying transmit powers. In one example, a device communicating with the base station can receive a plurality of T/P ratios each related to a power used by the base station to transmit over one of a plurality of carriers in a specific subframe or resource block, determine a power of a reference signal received from the base station over a carrier of the plurality of carriers, and process a data signal received over the carrier within the specific subframe or resource block based in part on applying, to the power of the reference signal, a T/P ratio of the plurality of T/P ratios corresponding to the carrier.

Abstract: Systems and methods for managing the transmission of multiple signals on one or more uplink (UL) channels using carrier aggregation in LTE-A systems. A UE simultaneously transmits signals such as ACK/NACK and periodic CSI using one or more uplink channels, such as a physical uplink shared channel (PUSCH) and/or a physical uplink control channel (PUCCH), by increasing the resources used to transmit at least one of those signals. According to one aspect, a UE simultaneously transmits ACK/NACK signals and periodic CSI signals by multiplexing those signals on the PUSCH. Certain aspects avoid frequently dropped periodic CSI signals and provide mechanisms to ensure that ACK/NACK signals are transmitted.
