  • Patent number: 12531618
    Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may transmit a first capability message to a network entity indicating that the UE may be capable of using a subset of antenna ports of a set of antenna ports for uplink sounding on a wireless band. Further, one or more antenna ports of the set of antenna ports may be available for the uplink sounding and the first capability message may include an indication of the set of antenna ports. The UE may then receive control signaling from the network entity indicating the subset of antenna ports that the UE should use for the uplink sounding based on the first capability message. As such, as part of the uplink sounding on the wireless band, the UE may transmit one or more sounding reference signals (SRSs) via the subset of antenna ports indicated by the control signaling.

  • Patent number: 12375322
    Abstract: Methods, systems, and devices for wireless communications are described. A wireless device may identify channel responses between antenna elements of antenna arrays of the wireless device and user equipments (UEs) at geographic locations within a coverage area of the wireless device. For example, the wireless device may identify the channel responses based on reference signal transmissions between the UEs and the wireless device. The wireless device may process the channel responses to identify one or more directional power peaks associated with the reference signal transmissions. The wireless device may, based on the one or more directional power peaks, detect phase error values, amplitude error values, or both common to the channel responses. The wireless device may adjust the signal communicated via at least a subset of the antenna elements based on the phase error values, the amplitude error values, or both and communicate with one or more of the UEs.

  • Publication number: 20250183947
    Abstract: Methods, systems, and devices for wireless communications are described. A network entity may obtain a single user, multi-input multi-output (SU-MIMO) channel between the network entity and a user equipment (UE), which may correspond to multiple SU-MIMO layers. The network entity may generate a transformed channel based on a selection of the multiple SU-MIMO layers. The selection may be based on a singular value decomposition (SVD) of the SU-MIMO channel, or a set of receive antennas at the UE, or a combination thereof. The network entity may generate an intermediate beamformer based on the transformed channel and may generate a per antenna full transmit power beamformer based on the intermediate beamformer. The network entity may output a beamformed signal to the UE, and a respective beamforming weight for each SU-MIMO layer of the multiple SU-MIMO layers may be based on the per antenna full transmit power beamformer.

  • Publication number: 20250141507
    Abstract: Methods, systems, and devices for wireless communication are described. For instance, a network entity may receive control information indicating a set of candidate geolocations within a target coverage area for the network entity. The network entity may transmit a signal that is beamformed via a set of antenna elements of an antenna array of the network entity in accordance with a set of antenna beamforming weights. The set of antenna beamforming weights may be identified based on a beam pattern performance criterion applied to a set of candidate radiation patterns of a spatial envelope model. The spatial envelope model may be based on a set of directions between the antenna array of the network entity and the set of candidate geolocations as well as a set of pathloss values associated with the set of candidate geolocations.
