Abstract: A method of wireless communications by a user equipment (UE) includes decoding information received from a base station via a physical downlink shared channel (PDSCH). The UE determines whether to update channel state feedback based on the decoded information. The channel state feedback is updated based on the determination to generate updated channel state feedback. The updated channel state feedback is transmitted to the base station. The UE is configured to update the channel state feedback without an additional measurement of a channel state information reference signal (CSI-RS).

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: A method for wireless communication by a user equipment (UE) includes receiving, from a base station, a reference signal on a wideband channel. The method further includes estimating, at the UE, the wideband channel based on receiving the reference signal. The method still further includes identifying, at the UE, a bottleneck band of the wideband channel based on a metric associated with the estimated wideband channel. The method also includes transmitting, to the base station, a channel state feedback report based on identifying the bottleneck band, the channel state feedback report indicating channel state information (CSI) associated with the estimated wideband channel. The method further includes receiving, from the base station, a transmission grant based on transmitting the channel feedback report.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may receive an assignment of a set of resources associated with a channel, where the set of resources includes a first subset of resources allocated for data transmission and a second subset of resources allocated for a reference signal. The wireless device may generate, from the reference signal in accordance with a minimum mean square estimation (MMSE) operation, a first set of multiple channel estimations per layer of the channel. The wireless device may generate, in accordance with a nonlinear two-dimensional interpolation of the channel, a second set of multiple channel estimations per layer of the channel and may perform a refinement operation utilizing the estimations to generate a channel estimation associated with multiple layers.
