    Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine one or more demodulation reference signal (DMRS) scrambling sequences using a low peak-to-average power ratio (PAPR) sequence generator, each corresponding to a respective port of one or more ports, the one or more ports being associated with a downlink multiple input multiple output (MIMO) communication, wherein the downlink MIMO communication is a discrete Fourier transform spread orthogonal frequency division multiplexing (DFT-s-OFDM)-based communication. The UE may receive the downlink MIMO communication including a DMRS according to an intra-slot DMRS pattern that indicates one or more time domain multiplexed symbols, each being at least partially allocated with at least one DMRS scrambling sequence of the one or more DMRS scrambling sequences. Numerous other aspects are described.

    Abstract: A transmitting device may select frequency domain resources for an alert transmission based on a severity level of the alert transmission. The transmitting device may determine a severity level of an alert transmission to be transmitted on one or more available channels. The transmitting device may determine a presence of one or more systems configured to transmit on one or more neighbor channels of the one or more available channels. The transmitting device may select, for the alert transmission, frequency domain resources within the one or more available channels based on the presence of the one or more systems and the severity level. The frequency domain resources for a highest severity level transmission are spaced further apart from the one or more neighbor channels in the frequency domain than resources for a lower severity level transmission. The transmitting device may transmit the alert transmission on the frequency domain resources.

    Abstract: Aspects of the techniques and apparatuses described herein provide an intra slot antenna diversity scheme that a user equipment (UE) may use to transmit uplink communications while mitigating antenna imbalance. In an intra slot antenna diversity scheme, a UE transmits an uplink communication by transmitting a first portion of the uplink transmission in a first part of a slot using a first subset of antennas and a second portion of the uplink communication in a second part of the slot using a second subset of antennas. A decision to apply an intra slot antenna diversity scheme may be made by a network node such as a base station. Numerous other aspects are described.
