Abstract: A method and apparatus may include measuring a space frequency downlink channel matrix. The space frequency downlink channel matrix reflects a channel response observed by the apparatus. The apparatus receives transmissions from an array of antennas of a network node. The method can also include determining a spatial channel vector. The method can also include determining scalar phase terms. The method can also include determining a Signal-to-Interference-Plus-Noise-Ratio scalar factor of the channel response observed by the apparatus. The method can also include transmitting an encoded form of the spatial channel vector. The method can also include transmitting an encoded form of the Signal-to-Interference-Plus-Noise-Ratio scalar factor. The method can also include transmitting an encoded form of the scalar phase terms.

Abstract: An example method, apparatus, and computer-readable storage medium are provided for panel activation at a user equipment. In an example implementation, the method may include a user equipment (UE) receiving a synchronization signal block (SSB) from a network node; receiving a panel activation request from the network node; measuring a plurality of beams received from the network node; activating one or more panels, the activating based at least on the panel activation request and/or the measuring; and transmitting, by the user equipment (UE): a first transmission of a physical random access channel (PRACH) using a first physical random access channel (PRACH) resource, a second transmission of the physical random access channel (PRACH) using a second physical random access channel (PRACH) resource configured for indicating the activating of one or more panels at the user equipment (UE), and wherein the first transmission and the second transmission are transmitted using a same transmit (Tx) beam from the user equipment (UE).

Abstract: Various communication system may benefit from the appropriate selection of communication parameters. For example, certain wireless communication systems may benefit from the user of a low-overhead high-rank codebook. A method can include determining a first partition of a precoding matrix with a higher resolution and a second partition of the precoding matrix with a lower resolution. The method can also include feeding back the first partition and the second partition.

Abstract: A method includes determining a number of polarizations. The method also includes determining a number of receive antennas that have a same polarization, determining a total number of receive antennas based on the number of polarizations and the number of receive antennas that have the same polarization; and applying singular value decomposition precoding on all the receive antennas with the same polarization.
