Abstract: Methods, systems, and devices for wireless communications are described. A base station may determine the subcarrier spacing and carrier frequency used by a user equipment (UE) for communicating with the base station. The base station may select a sounding reference signal (SRS) configuration for the UE that is based on the subcarrier spacing and carrier frequency used by the UE. The SRS configuration may define the temporal spacing between repetitions of the SRS. The base station may indicate the SRS configuration to the UE so that the UE transmits repetitions of the SRS according to the SRS configuration. The base station may measure the SRS repetitions from the UE to determine the Doppler frequency for the uplink channel. The base station may use the uplink Doppler frequency to select a demodulation reference signal (DMRS) configuration for the UE.

Abstract: A user equipment (UE) may multiplex peak suppression information message (PSIM) on a physical uplink shared channel (PUSCH) with data for efficient implementation of PSIMs for peak to average power ratio (PAPR) reduction. A UE may clip peaks from a signal to be transmitted and capture information of the clipped peaks into a PSIM. The UE may then multiplex the PSIM on the PUSCH such that a receiving device (for example, a base station) may receive the signal and reconstruct the signal (for example, PUSCH data) using the PSIM. According to some aspects, each PUSCH symbol may include a PSIM for a previous PUSCH symbol (for example, such that causality is preserved if multiplexing PSIM and data for each PUSCH symbol). Various aspects of the techniques described herein may further provide for PSIM positioning in frequency, PSIM modulation, PSIM channel coding, PSIM multiple-input multiple-output (MIMO) configurations, among other examples.

Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device (e.g., a user equipment (UE) or base station) may reduce a peak to average power ratio (PAPR) by clipping signals transmitted to a receiving device according to a clipping level. The receiving device may receive, from the transmitting device, an indication of the clipping level associated with a reference signal. The receiving device may receive the reference signal and identify distortions based on the clipping level. The receiving device may iteratively reconstruct peaks of the clipped reference signal until the receiving device is able to obtain accurate pilot symbols for use in channel estimation. The techniques described herein may enable receiving devices to improve efficiency and reliability of communications by improving channel estimation, which may increase the probability of successfully decoding transmitted information.

Abstract: Methods, systems, and devices for wireless communications are described. An interfering base station may transmit to a neighboring base station a configuration to measure beam resources for a plurality of PAPR reduction beams. The neighboring base station may forward this measurement configuration to an associated UE. The UE may then take measurements of the interfering base station's PAPR reduction beams in accordance with the configuration and transmit the report to its serving base station. The neighboring base station may then compile a headroom report and transmit the headroom report to the interfering base station. The interfering base station may then adjust its PAPR reduction beams based on the headroom report.

Abstract: Methods related to wireless communication systems and the transmission of code blocks on such systems are provided. A wireless communication device interleaves a plurality of code block segments in time and frequency. The segments are interleaved by mapping a first code block segment of the plurality of code block segments to a first resource located at a first time and a first frequency, wherein the first code block segment is associated with a first code block, and mapping a second code block segment of the plurality of code block segments to a second resource based on at least one of the first time or the first frequency of the first resource and a code block proximity parameter, wherein the second code block segment is associated with a second code block different from the first code block. The device then transmits the plurality of interleaved code block segments. Other features are also claimed and described.

Abstract: Certain aspects of the present disclosure provide techniques for beam management using adaptive learning. Certain aspects provide a method that can be performed by a node, such as user equipment (UE) or a base station (BS). The node determines one or more beams to utilize for a beam management procedure using adaptive learning. The node performs the beam management procedure using the determined one or more beams. In some aspects, the node uses an adaptive reinforcement learning algorithm to select beams for measurement in beam discovery procedure. The node may adaptive the beam management algorithm based on feedback associated with the beam selection, such as based on a throughput achieved using a beam pairing determined during the beam management procedure.

Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may receive, using a first receive port, a first signal within a first frequency band, where the first receive port may be associated with a first receive beam. The wireless device may also receive, using a second receive port, a second signal within the first frequency band concurrently with receiving the first signal, where the second receive port may be associated with a second receive beam. After receiving the first and second signals, the wireless device may process both signals. Processing the signals may include decoding both of the signals, measuring both of the signals, and/or decoding one of the signals and measuring the other of the signals. To support concurrent reception over multiple receive beams within a single frequency band, the wireless device may employ an idle antenna panel and corresponding receive ports.

Abstract: A direction-controlled PAPR reduction is provided in which a base station transmits a PAPR reduction signal using a subset of antenna beams selected from a null space plurality of antenna beams. The subset of antenna beams is selected such that the PAPR reduction signal is not directed having a relatively-high path gain to a UE and/or so that the PAPR reduction signal power is concentrated in directions that have a relatively-lo path gain to the UE.

Abstract: Technology herein selectively adjusts the frequency with which beam scanning is performed. Systems and methods herein determine present conditions of the UE and determine whether adjusting the current frequency of beam scanning is desired. Based at least on the present conditions, the current frequency may be reduced, increased, or maintained in order to balance the use of processing resources with the instability of channels.
