Abstract: Methods, systems, and devices for wireless communications are described. A transmitting device may select a scrambling sequence to use per symbol to reduce variance in a non-linearity parameter for a power amplifier (PA) output between a data symbol and a pilot symbol based on a PA model for at least one pilot symbol or one or more parameters of the model. The receiving device may indicate a capability to blindly estimate the scrambling sequence the transmitting device selected to the transmitting device. If the transmitting device does not receive the capability message from the receiving device or if the capability message indicates the receiving device is not capable of blind estimation, the transmitting device may indicate the selected scrambling sequence to the receiving device. Otherwise, the transmitting device may not indicate the selected scrambling sequence to the receiving device, and the receiving device may blindly estimate the scrambling sequence.

Abstract: Certain aspects of the present disclosure provide techniques for envelope tracking schemes for a node in a wireless communication network. One aspect provides a method for wireless communication by a transmitter device. The method generally includes: combining envelopes associated with subbands of an input signal to be amplified for transmission based on a combination function; amplifying, via an amplifier, the input signal to generate a transmission signal, the input signal being amplified based on a combined envelope signal, representing the combination of the envelopes, received at a supply input of the amplifier; and transmitting the transmission signal to a receiver device.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration of a sleep mode, the configuration indicating a coding scheme used for a wake-up signal (WUS). The UE may receive a WUS message, the WUS message being encoded with product coding, wherein a coding stage of the product coding comprises locally-decodable coding. The UE may receive a communication based at least in part on the WUS message. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, an UE may receive an indication of a configuration for receiving reference signals (RSs) and for transmitting a digital pre-distortion (DPD) measurement. The UE may receive the RSs from a network node. The UE may transmit a first signal that indicates the DPD measurement as observed via the RSs at the first UE, the first signal configured for coherent combination over the air with a second signal that indicates a DPD measurement as observed via the RSs at a second UE, the first signal and the second signal scheduled for transmission via overlapping network resources. Numerous other aspects are described.

Abstract: An injury protection accessory for a riding vehicle (e.g., motorcycle), the accessory comprising: at least one shield (4), disposed at the side(s) of the riding vehicle, the shield comprising: a substantially vertical hinge (12), attached to the body or the chassis of the riding vehicle; and one or more substantially horizontal bars (10), attached to the hinge; the shield having an open state, in which one edge of the shield is separated from the body of the vehicle, thereby allowing the rider thereof to get off the vehicle, and a closed state, in which both sides of the shield are engaged with the body of the vehicle, thereby protecting the rider from injury.
