Abstract: A wireless communication at a user equipment includes selecting one of a first energy detection threshold and a second energy detection threshold, detecting an energy level, determining that the energy level is less than the selected one of the first energy detection threshold and the second energy detection threshold, and transmitting data after determining that the energy level is less than the selected one of the first energy detection threshold and the second energy detection threshold. In some examples, the first energy detection threshold is for a first duplex mode of operation (e.g., a half-duplex mode of operation), and the second energy detection threshold is for a second duplex mode of operation (e.g., a full-duplex mode of operation).

Abstract: In some implementations, a first ultra-wideband (UWB) device may determine a respective time offset for each scrambled timestamp sequence (STS) in a series of STS used for ranging in a UWB ranging session between the first UWB device and the second UWB device, wherein the respective time offset for each STS in the series of STS is determined in accordance with time offset information shared between the first UWB device and the second UWB device. The first UWB device may transmit the series of STS via UWB radio frequency (RF) signals during the UWB ranging session, wherein each STS in the series of STS is transmitted with the respective time offset.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may be configured to transmit, to a base station via a reconfigurable surface at a first transmission occasion, a first reference signal associated with a first reflection matrix configuration used by the reconfigurable surface to reflect signals, the first reflection matrix configuration included within a set of reflection matrix configurations. The UE may then transmit, to the base station via the reconfigurable surface at a second transmission occasion, a second reference signal associated with a second reflection matrix configuration used by the reconfigurable surface to reflect signals, the second reflection matrix configuration included within the set of reflection matrix configurations. The may then communicate with the base station via the reconfigurable surface based on transmitting the first reference signal, the second reference signal, or both.

Abstract: Methods, systems, and devices for wireless communications are described. The described techniques support decoupled uplink and downlink communications via reconfigurable intelligent surfaces. Generally, the described techniques provide for using different passive network nodes for uplink and downlink communications. A user equipment (UE) may receive, from a base station, an indication of a first transmission configuration indicator state for downlink communications with the base station and a second transmission configuration indicator state for uplink communications with the base station. The UE may receive, from the base station via a first passive device (e.g., a first reconfigurable intelligent surface (RIS)) associated with the first transmission configuration indicator state, a downlink message in a radio frame. The UE may transmit, to the base station via a second passive device (e.g., a second RIS) associated with the second transmission configuration indicator state, an uplink message in the radio frame.

Abstract: Methods, systems, and devices for wireless communications are described. A UE may receive, from a base station, an indication of a degree of UE loading for at least one of a set of reconfigurable reflective surfaces that are configured to assist in communications between the UE and the base station. The UE may select a reconfigurable reflective surface for use in the communications between the UE and the base station based on the degree of UE loading of the selected reconfigurable reflective surface, and transmit a signal to the base station via the selected reconfigurable reflective surface. In some cases, the UE may receive, from the base station, an indication for the UE to use a different reconfigurable reflective surface than the selected reconfigurable reflective surface, and may transmit a second signal to the base station via a second reconfigurable reflective surface based on the indication.
