  • Publication number: 20250096863
    Abstract: Aspects relate to mechanisms for generating an enhanced beamforming codebook to cover an out-of-coverage region of an antenna module of a wireless communication device (e.g., a UE). The UE may include an initial beamforming codebook configuring a plurality of beam weights intended to cover an in-coverage region corresponding to a boresight direction and a neighborhood thereof of the antenna module. The UE may further configure one or more additional sets of beam weights intended to cover the out-of-coverage region beyond the boresight direction and the neighborhood thereof and then add the one or more additional sets of beam weights to the initial beamforming codebook to produce the enhanced beamforming codebook.

  • Patent number: 12237893
    Abstract: Methods, systems, and devices for wireless communications are described. A codebook adaptation may be performed for a flexible user equipment (UEs) to determine a codebook for a physical configuration of the UE. For example, if the UE determines that the physical configuration does not correspond to a pre-loaded codebook in its memory, the UE may provide information about the physical configuration to a base station to determine a corresponding codebook. Additionally, the UE may request that the base station provide channel information to assist with the codebook determination. In some cases, this request may indicate for the base station to allocate a specific number of channel state information reference signal symbols that the UE can use for the codebook determination. Additionally or alternatively, the UE may generate the codebook internally and then signal to the base station a request for a beam refinement procedure with the generated codebook.

  • Patent number: 12184365
    Abstract: A dual-polarized multiple-input-multiple-output (MIMO) mobile device is provided that includes a first array of antennas and a second array of antennas. Based upon a blockage of at least one of the array of antennas being less than a blockage threshold, the mobile device operates in a default configuration in which a default polarization selection from the second array is used in combination with a fixed polarization selection from the first array to form a first MIMO layer signal and a second MIMO layer signal. Should the blockage exceed the blockage threshold and an optional performance threshold be satisfied, the mobile device may operate in a dynamic configuration in which a dynamic polarization selection from the second array is reversed as compared to the default polarization selection.
