    Abstract: Methods, systems, and devices for wireless communications are described. A configuration for a reference signal used to determine a non-linear behavior of transmission components at a transmitting device may be determined. The configuration for the reference signal may be determined based on signaling transmitted by the transmitting device, signaling transmitted by a device that receives the reference signal, or both. Additionally, or alternatively, the configuration for the reference signal may be determined based on a configuration of other signals transmitted by the transmitting device prior to or concurrently with the transmission of the reference signal. The determined configuration may be used to generate and transmit the reference signal or to determine a configuration of a received reference signal. In both cases, a non-linear response of transmission components at the transmitting device may be determined based on the reference signal.

    Abstract: Wireless communications systems and methods related to considering channel variations for medium sharing in a spatial domain are provided. A first wireless communication device transmits one or more reservation response signals indicating spatial channel information in response to a reservation request for a transmission opportunity (TXOP) in a frequency spectrum. The first wireless communication device receives, from a second wireless communication device, a communication signal from a first spatial subspace during the TXOP based on the reservation request. In one embodiment, the first wireless communication device may repeat a transmission of the reservation response signal after transmitting a portion of the communication signal. In another embodiment, the first wireless communication device may include a channel variation parameter in the reservation response signal.

    Abstract: Methods, systems, and devices for wireless communications are described. A base station may associate a first port and a second port each with a set of antenna elements based on a first and a second linear precoding vector, where the phases of the ports are coherent. The base station may generate coefficients indicating a first combination and a second combination of a first data set for a first user equipment (UE) and a second data set for a second UE. In some cases, the base station may apply the first linear precoding vector to the first combination, apply the second linear precoding vector to the second combination, and transmit the first combination using a first transmission beam corresponding to the first port and the second combination using a second transmission beam corresponding to the second port to the first and second UEs.
