Abstract: Techniques are described herein for addressing tone misalignment between signals of a first radio access technology (RAT) and signals of a second RAT in a combined signal. In some wireless communications systems, the tones of uplink (UL) signals may be shifted up or down based on the configuration of the particular RAT. If UL signals of the first RAT are not shifted in frequency and UL signals of the second RAT are shifted in frequency, processing the combined signal may include additional processing to account for the mismatch.

Abstract: Methods, systems, and devices for wireless communication are described in which a number of reference signal processes may be configured for a number of slots in a radio frame, and a corresponding reference signal process for each slot may be based at least in part on a location of the slot within the radio frame and a number of configured reference signal processes. An indication may be provided to a user equipment (UE) in each slot that indicates a presence or absence of a reference signal transmission in the slot.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may determine to decode or refrain from decoding a transport block (TB) transmitted from a base station based on a decodability condition. The decodability condition may include whether an effective UE throughput for decoding the TB is greater than a predetermined decoding throughput threshold or not. If the effective UE throughput is greater than the predetermined decoding throughput threshold, the UE may refrain from decoding the TB. In some cases, the TB may be a subsequent transmission from the base station based on an initial transmission not being correctly decoded, and the UE may refrain from decoding the subsequent transmission.

Abstract: Aspects of the present disclosure provide methods, apparatus and computer program products for turbo decoder throttling (e.g., in an effort to limit power consumption by a user equipment (UE)). According to an aspect, the UE may identify an error in a received code block (CB) of a transport block (TB). The UE may enter a throttle mode in a decoder at the UE in response to the identified error, wherein the throttle mode determines how one or more subsequent CBs are processed. Numerous other aspects are provided.

Abstract: Methods, systems, and devices for half-duplex frequency division duplexing (HD-FDD) hybrid automatic repeat request (HARQ) operation are described. The base station may receive a message from a user equipment (UE) indicative of a duplexing capability of the UE. The base station may then select a HARQ process limit based on the duplexing capability. In some examples, the base station may anticipate a collision between an uplink (UL) transmission and a downlink (DL) subframe based on the selected HARQ process limit. The base station may then schedule a transmission to avoid the anticipated collision. In some examples, the base station may limit a number of configurations available for channel quality indicator (CQI) or a precoding matrix indicator (PMI).

Abstract: Systems, methods, apparatuses, and computer-readable storage media for managing power consumption of a mobile device are disclosed. The systems, method, apparatus, and computer-readable storage medium may cause the base station to identify an energy metric associated with a mobile device, and to configure the transmission between the base station and the mobile device based at least in part on the energy metric. The configuration of the transmission may reduce the power consumption of the mobile device for processing the transmission.

Abstract: The disclosure relates in some aspects to techniques for improved channel estimation. For example, a device can specify a pilot structure where pilot density differs over time. As another example, a device can indicate that a pilot from a prior transmission time interval (TTI) can be used for channel estimation. As another example, a device can employ frequency domain physical resource block (PRB) bundling with the bundling information signaling. As yet another example, a device can use an adjustable traffic-to-pilot ratio (TPR) for throughput optimization. Other aspects, embodiments, and features are also discussed and claimed.

Abstract: Techniques are described herein that allow a user equipment (UE) to configure a subcarrier spacing value while monitoring synchronization signals of neighboring cells. In some wireless communication systems, synchronization signals in given radio frequency spectrum band may be transmitted using one of a plurality of different subcarrier spacings. In some cases, a network entity, such as a base station, may transmit an indication to the UE that indicates the subcarrier spacing used by a cell to transmit a specific set of synchronization signals. In some cases, the UE may select a subcarrier spacing based on a database of subcarrier spacings stored locally by the UE. In some cases, the UE may select the subcarrier spacing based on a predetermined configuration.
