Abstract: Certain aspects of the present disclosure relate to techniques for estimating a channel using soft-windowing. A user equipment (UE) may determine, based on a cyclic prefix (CP) length of a channel, a timing window for sampling reference signals transmitted on the channel, determine a set of weights to apply to samples obtained within the determined timing window, wherein each weight corresponds to a sample obtained within the determined window, and estimate the channel by applying the weights to the samples.

Abstract: Systems, apparatuses, and methods for computing transport block size (TB S) for channels with shortened transmission time interval (sTTI). An initial size may be determined based on one or more TBS tables. The initial size may be scaled by a factor associated with an sTTI channel. A TBS table is selected based on the one or more TBS tables. The scaled size may be rounded based on the selected TBS table to generate a TBS for the sTTI channel.

Abstract: Certain aspects of the present disclosure relate to methods and apparatus relating to intelligent resource assignment to increase throughput in LTE multiple input multiple output (MIMO) and carrier aggregation (CA) capable devices. In certain aspects, a MIMO and CA capable wireless communication device communicates with a base station (BS) on multiple component carriers (CCs) through multiple radio frequency (RF) chains. In such aspects, the device tentatively switches one or more first RF chains, not assigned to a first CC of the multiple CCs, to the first CC for evaluating a rank of the first CC. The device then determines that the first CC has a higher rank indication (RI) with the one or more RF chains. The device subsequently evaluates one or more performance factors, in conjunction with the higher rank, based on which the device then additionally assigns one or more second RF chains to the first CC.

Abstract: A method, a computer-readable medium, and an apparatus are disclosed for energy efficient multichannel communications. In one aspect, the apparatus may communicate using a plurality of channels working in parallel where the plurality of channels may share an LNA. Additionally, the apparatus may determine a set of parameters for the plurality of channels to maximize energy efficiency. The apparatus may therefore configure the plurality of channels based on the set of parameters. As such, the apparatus supports multichannel communications with a common LNA structure while providing energy optimization for the multichannel communications. Accordingly, multichannel communications can be provided using a shared LNA structure that reduces implementation cost and more efficiently utilizes available power resources.

Abstract: Certain aspects of the present disclosure generally relate to wireless communications and, more particularly, to dynamically updating filtering configuration in modem baseband processing. A method is provided for wireless communications. The method may be performed, for example, by a user equipment (UE). The method generally includes detecting one or more conditions regarding one or more metrics of a received signal and updating, based on the detection, a configuration of one or more filters designed to mitigate an effect of spurious signals associated with (e.g., that fall within) a bandwidth of the received signal.
