Abstract: Methods, systems, and devices for wireless communications are described. A network node may transmit a control message identifying a configuration for a physical layer channel that is dedicated to carrying beam management information for communications with a user equipment (UE). The network node may transmit an indication of beam management parameters to one or more UEs via the physical layer channel that is dedicated to carrying beam management information. The UE may perform a beam management procedure using the one or more beam management parameters, such as identifying one or more beams for communications with the network node. The UE and the network node may communicate uplink signaling, downlink signaling, or both using the identified one or more beams.

Abstract: Aspects described herein relate to switching waveforms in a waveform switching gap. In an aspect, using a transceiver, a first signal of a first waveform can be communicated. Assistance information related to switching the transceiver to use a second waveform can be communicated as well, and based at least in part on the assistance information, the transceiver can be switched to use a second waveform. Using the transceiver, a second signal of a second waveform can be communicated.

Abstract: Methods, systems, and devices for wireless communication are described. A transmitting device may determine a power amplifier operating mode associated with non-linear distortion of an input waveform for a power amplifier, where the power amplifier operating mode may be from a set of two or more power amplifier operating modes each associated with respective amounts of the non-linear distortion. The transmitting device may transmit a set of reference signals associated with estimation of a wireless channel for a transmission, and the transmitting device may further transmit an additional set of reference signals associated with non-linear distortion mitigation for the transmission. In some examples, a resource density of the additional set of reference signals may be based on the power amplifier operating mode. In some examples, the transmitting device may transmit an indication of the power amplifier operating mode, the resource density, or both, to a receiving device.

Abstract: In a wireless network, a frame structure may include a padding duration at the start of every half subframe to ensure that an integer number of symbols fit within a duration of the half subframe. In some aspects, to avoid wasting time domain resources, the padding duration may be utilized for other purposes. For example, because a single carrier waveform is not bound to a fixed Fast Fourier Transform size, a wireless node may use the padding duration to transmit a single carrier symbol that has a shorter length than a full symbol associated with a subcarrier spacing. Additionally, or alternatively, in cases where a wireless node is configured to transmit or receive a signal in a first symbol of a half subframe that is associated with a different power level than a preceding symbol, the padding duration may be used to adapt a transmit power or a receive gain.

Abstract: Methods, systems, and devices for wireless communications are described. In some systems, a base station may configure a set of transmission parts each including different sets of time domain resources or different sets of frequency domain resources, or both, and may specify a waveform type for each of the set of transmission parts. In some examples, the base station may configure the set of transmission parts for a user equipment (UE) and, accordingly, the UE and the base station may communicate over a transmission part of the set of transmission parts via signaling that is based on a waveform type that is associated with the transmission part over which the UE and the base station communicate. The base station may control over which transmission part of the set of transmission parts the UE and the base station communicate via a configured timer or via explicit activation and deactivation signaling.

Abstract: Wireless communications systems and methods related to multiplexing of synchronization blocks (SSBs), control resource sets (CORESETs), and system information blocks (SIBs) are provided. A user equipment (UE) receives, from a base station (BS), a first SSB of a first group of SSBs of an SSB burst set, wherein the first group of SSBs and a second group of SSBs of the SSB burst set are spaced apart in time by a group of CORESETs and SIBs. The group of CORESETs and SIBs comprises one CORESET and at least one SIB for each SSB of the first group of SSBs. The UE receives, in a first CORESET of the group of CORESETs and SIBs based on the first SSB, SIB scheduling information. The UE receives, based on the SIB scheduling information, a first SIB of the group of CORESETs and SIBs.

Abstract: A base station may schedule a plurality of synchronization signal blocks (SSBs) in an extended discovery burst (DRS) transmission window including a plurality of candidate SSBs including at least two candidate SSBs with a same SSB beam index, and transmit the plurality of SSBs based on the scheduling of the plurality of SSBs in the extended DRS transmission window. A UE may monitor for a plurality of SSBs in the extended DRS transmission window including the plurality of candidate SSBs including at least two candidate SSBs with the same SSB beam index, and perform measurements based on SSBs of the plurality of SSBs received from the base station. The base station may transmit a signal indicating one or more scheduling parameters of the plurality of SSBs, and the UE may determine SSB index of each candidate SSB of the plurality of candidate SSBs.
