    Abstract: Methods, systems, and devices for wireless communications are described. In one example, a receiving device (e.g., a UE) may transmit, to a transmitting device (e.g., a base station), a capability indicator indicating a capability of the receiving device to perform peak reconstruction using soft metrics (e.g., expected value, covariance) on symbol decisions. The receiving device may receive, from the transmitting device and based on the capability indicator, control signaling indicating a clipping level applied to generate a signal and a subset of peaks clipped from the signal. The receiving device may receive the signal generated in accordance with the control signaling from the transmitting device and may decode a reconstructed signal based on performing the peak reconstruction on the signal using the soft metrics on symbol decisions, the clipping level, and the subset of the peaks clipped from the signal.

    Abstract: The apparatus is configured to performing a beam scan operation. The beam scan operation may be part of an active beam scanning process. The apparatus is also configured to deactivate the beam scan process upon determining that the apparatus is in a first state corresponding to at least one of a first set of conditional states. The apparatus is configured to determine a state change of the apparatus. Additionally, the apparatus is configured to activating the beam scanning process upon determining that the apparatus is in a second state corresponding to at least one of a second set of conditional states different from the first set of states. The apparatus is also configured to performing the beam scan operation upon activating the beam scanning process.

    Abstract: Methods, systems, and devices for wireless communications are described. Some wireless communications systems may utilize beamforming techniques to process wireless communications transmitted in millimeter wave (mmW) frequency ranges. In such cases, a user equipment (UE) may perform lattice reduction (LR)-based preprocessing for a received resource element (RE), which allows the UE to utilize demapping techniques (e.g., minimum mean square error (MMSE)-based demapping techniques or successive interference cancellation (SIC) demapping techniques) that are less computationally-complex than conventional demapping techniques (e.g., maximum likelihood (ML)-based demapping techniques) while providing a similar performance as conventional techniques. Further, due to mmW systems' robustness to time-dispersion, the UE may apply the same LR to multiple REs across multiple symbols in the time domain and across multiple sub-carriers in the frequency domain. The computational cost of performing the LR calculation may be spread across multiple REs and further increase the efficiency of utilizing low-complexity demapping techniques.

    Abstract: Methods, apparatuses, systems, and devices are described for wireless communication in an unlicensed spectrum. In one method, a clear-to-send (CTS) signal may be employed to manage or otherwise limit potential interference for communications in the unlicensed spectrum. For example, communications using long term evolution (LTE) may employ an unlicensed spectrum, particularly for small cell deployment. In such case, the LTE communications may be protected from interference due to communications by other networks, such as WiFi, using the unlicensed spectrum.

    Abstract: Backhaul traffic reliability is improved in unlicensed spectrum bands by using cross-protocol channel sensing and reservation. Physical carrier sensing may be employed to scan channel quality of a plurality of carriers of an unlicensed spectrum band and select a carrier for use in a wireless backhaul communications link between a first base station and a second base station based on the scanned channel quality. The described features may further include the first base station transmitting a self-addressed reservation frame on the selected first carrier prior to transmission of backhaul data from the first base station to the second base station over the first carrier.

    Abstract: A receiving device may identify a mutual information associated with a code block. The receiving device may identify whether the code block is decodable based on the mutual information. The receiving device may skip decoding the code block if the code block is identified as being not decodable. The receiving device may decode the code block if the code block is identified as being decodable. The code block may be identified as being not decodable if the mutual information is less than a second threshold. The code block may be identified as being decodable if the mutual information is greater than the second threshold. The receiving device may identify the second threshold based on an MCS associated with the code block or a code block length of the code block.
