  • Patent number: 10181880
    Abstract: Apparatuses, methods, and systems zone precoding are disclosed. One method includes training a transmission channel between a base station and each of a plurality of users and determining a precoding of transmission signals to each of the plurality of users from the base station. The training includes determining a transmission zone for each of the plurality of users, wherein the transmission zone includes an angle of direction of a directional beam to each user, and a deviation of the angle of direction. Determining a precoding of transmission signals to each of the plurality of users from the base station, includes determining an initial precoding for each of the users based on the transmission zone associated with the user, and constructing the precoding for each user by adjusting the initial precoding for each user based on the transmission zone determined for each of the other users.

  • Publication number: 20190013843
    Abstract: Apparatuses, methods, and systems for precoding multi-carrier signals are disclosed. One method includes obtaining a transmission channel matrix between a terminal and a plurality of separate users, wherein the transmission channel matrix includes channel estimates for a plurality of subcarriers of the multi-carrier signal, wherein the terminal is one of a plurality of terminals interfaced with a central processing unit, and wherein the terminal communicates with the plurality of spatially separate user with the multi-carrier signals. The method further comprises determining a precoding for the terminal based on a distribution of user signal power across the transmission channel between the terminal and the plurality of spatially separate user, and determining a precoding for the central processing unit based on the precoding for the terminal and based on the transmission channel matrix, wherein a precoding matrix for the central processing unit is multi-carrier signal dependent.

  • Patent number: 10084517
    Abstract: Apparatuses, methods, and systems for precoding multi-carrier signals are disclosed. One method includes obtaining a transmission channel matrix between a terminal and a plurality of separate users, wherein the transmission channel matrix includes channel estimates for a plurality of subcarriers of the multi-carrier signal. A channel dimension reduction matrix is determined based upon a composite of the channel estimates for the plurality of subcarriers, wherein dimensions of the channel dimension reduction matrix are less than dimensions of the transmission channel matrix. The method further includes determining a precoding matrix for the terminal based on the channel dimension reduction matrix, wherein the precoding matrix is multi-carrier signal independent, determining an effective channel based on a channel estimate of the transmission channel and based on the precoding matrix of the terminal, and determining a precoding matrix for the central processing unit based on the effective channel.

  • Patent number: 9867192
    Abstract: A method for operating a UE includes receiving, by the UE during an initial access sequence, a plurality of first inbound beams each transmitted by a communications controller in a different transmit direction over a first carrier, where the first inbound beams have a different subcarrier frequency range from each other, generating values of a receive metric in accordance with the first inbound beams, selecting one of the first inbound beams in accordance with the receive metric values, transmitting, by the UE, an indication of the selected first inbound beam, and receiving, by the UE, a second inbound beam transmitted by the communications controller in a transmit direction in accordance with the indication of the selected first inbound beam, where the second inbound beam has a second subcarrier frequency range of the first carrier that is different than a first subcarrier frequency range of the selected first inbound beam.
