Abstract: The disclosure relates in some aspects to techniques for improved channel estimation. For example, a device can specify a pilot structure where pilot density differs over time. As another example, a device can indicate that a pilot from a prior transmission time interval (TTI) can be used for channel estimation. As another example, a device can employ frequency domain physical resource block (PRB) bundling with the bundling information signaling. As yet another example, a device can use an adjustable traffic-to-pilot ratio (TPR) for throughput optimization. Other aspects, embodiments, and features are also discussed and claimed.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may communicate signaling with a network entity, the signaling indicating a first bandwidth size and a second bandwidth size associated with a projection parameter (W1) and a compression parameter (W2), respectively. The second bandwidth size may be less than the first bandwidth size. In some cases, the UE may determine W1 and W2 based on a first machine learning (ML) model and a second ML model, respectively. The UE may project a portion of received channel state information (CSI) associated with the first bandwidth size onto a sub-space defined by W1 and may compress a portion of the projection associated with the second bandwidth size based on W2. The UE may transmit channel state feedback including the projection, the compression of the projection, a compression of W1, a compression of W2, or any combination thereof.

Abstract: A base station performs joint channel estimation for a set of physical uplink control channels (PUCCHs), where one or more PUCCHs of the set of PUCCHs comprises a corresponding DMRS from a user equipment (UE). The UE receives an indication to transmit the set of PUCCHs, one or more PUCCHs of the set of PUCCHs comprising a DMRS from the base station. The base station transmits, and the UE receives, spatial filter or power control information elements for each PUCCH of the set of PUCCHs. The UE transmits the PUCCHs comprising corresponding DMRS based on a same spatial filter with a same power control parameters, spatial filter or power control information element for a first PUCCH of the set of PUCCHs indicating the same spatial filter or same power control parameter, the set of PUCCHs having phase continuity.

Abstract: Disclosed are techniques for wireless positioning. In an aspect, a user equipment (UE) may send, to a first entity, first information indicating a maximum number of positioning signal transmissions or a maximum power for positioning signal transmissions that the UE can support. The UE may receive, from the first entity, configuration information for changing a positioning mode of the UE to a positioning mode selected from a first positioning mode and a second positioning mode. The UE may perform a positioning operation according to the selected positioning mode. In some aspects, the first positioning mode is a normal positioning mode in which the UE sends UL positioning reference signals to a plurality of TRPS, and the second positioning mode is a UL power-limited mode in which the UE sends UL positioning reference signals to only one or a small number of TRPs.

Abstract: Methods, systems, and devices for wireless communications are described. A example method for wireless communication at a reconfigurable reflective surface comprises receiving one or more signals from a first wireless device and determining, based at least in part on the one or more signals, measurement information pertaining to a wireless channel between the reconfigurable reflective surface and the first wireless device. The example method may further include determining, based at least in part on the measurement information, a set of weights for a plurality of reflective elements of the reconfigurable reflective surface to be used in reflecting communications between the first wireless device and a second wireless device.
