Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) and a network entity may support communication of a compressed channel state information (CSI) feedback. The UE and the network entity may use closed-loop feedback to improve beamforming tracking accuracy. For example, the UE may receive a CSI reference signal (CSI-RS) that is beamformed based on a channel estimate of a sounding reference signal (SRS) or a previous CSI feedback, or both. The UE may transmit a feedback message including compressed CSI that is generated through encoding a measurement of the CSI-RS. The compressed CSI may be generated based on a predicted channel estimate at the network entity, determined based on the channel estimate of the SRS or the previous CSI feedback.

Abstract: This disclosure provides systems, methods and apparatus, including computer programs encoded on computer storage media, for channel state information (CSI) report structure for dynamic antenna port adaptation. In some aspects, a user equipment (UE) and a network entity may support a CSI report configuration according to which the UE may include a respective set of CSI parameters for each of multiple codebooks. For example, the UE may compute a respective set of CSI parameters for each of multiple codebooks in accordance with a CSI report configuration and may transmit a CSI report including the respective sets of CSI parameters for each of the multiple codebooks. The network entity may use the respective sets of CSI parameters for each of the multiple codebooks to inform a dynamic antenna panel configuration update at the network entity.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may inform a base station of multiple transmission-antenna switching capabilities supported by the UE. The supported transmission-antenna switching capabilities may include a first transmission-antenna switching capability and a second transmission-antenna switching capability. The UE may receive a message that triggers the UE to switch from using a first configuration associated with the first transmission-antenna switching capability to using a second configuration associated with the second transmission-antenna switching capability. The UE may perform a sounding procedure using the second configuration associated with the second transmission-antenna switching capability based on receiving the message.

Abstract: Methods, systems, and devices for wireless communications are described. A surface used to reflect radio frequency signals may receive requests from multiple devices to configure a set of reflection coefficients. Each request may include a set of reflection coefficients and an indication of a priority level of communications associated with the set of reflection coefficients. A set of reflection coefficients included in a message transmitted from a device may be based on a position of another device relative to the device and the surface. The surface may configure a set of reflection coefficients based on the priority levels associated with the sets of reflection coefficients received in the requests.

Abstract: Methods, systems, and devices for wireless communications are described. For instance, a user equipment (UE) may receive. from a base station, control signaling for a first sounding reference signal. The UE may determine, based on the configuration and a set of parameters associated with partial frequency sounding of the first sounding reference signal, a subset of a set of re sources configured for the first sounding reference signal, where the subset of the set of resources excludes at least one resource of the set of resources. The UE may transmit, to the base station, a second sounding reference signal over the subset of the set of resources.

Abstract: Techniques related to multi-layer wireless communications are disclosed. Some aspects of the disclosure relate to devices and methods for determining a transmission power boost for a phase-tracking reference signal (PT-RS). A wireless user equipment (UE) may map a multi-layer uplink transmission to a plurality of PT-RS ports by distributing the layers of the multi-layer uplink transmission among the plurality of PT-RS ports. The UE may determine a first transmission power boost for a first PT-RS port, and a second transmission power boost, different from the first transmission power boost, for a second PT-RS port. The UE may transmit a first PT-RS corresponding to the first PT-RS port utilizing the first transmission power boost, and the second PT-RS corresponding to the second PT-RS port, frequency division multiplexed with the first PT-RS, utilizing the second transmission power boost. Other aspects, embodiments, and features are also claimed and described.

Abstract: The described techniques relate to improved methods, systems, devices, or apparatuses that support channel state information feedback for semi-open-loop and open-loop schemes. The described techniques provide for a user equipment (UE) to determine an open-loop, semi-open-loop, or closed-loop transmission scheme for deriving channel quality information (CQI). In the case of determined open-loop transmission scheme, the UE may select a transmission scheme corresponding to a time offset value and a precoder cycling granularity value. The UE may determine one or more of a time offset value, a precoder cycling granularity value, and a precoding matrix indicator (PMI) for a channel state information (CSI) report, and generate CQI accordingly. Additionally, the UE may include the determined values in the CSI report to indicate the transmission scheme used for the CQI derivation. Based on the CQI, the base station can then determine the transmission scheme and perform link adaption accordingly.
