  • Transmitted precoding matrix indicator (TPMI) determination for new radio (NR) frequency range 1 (FRI) single user (SU) multiple input multiple output (MIMO) in an uplink
    Patent number: 12700896
    Abstract: A precoder index is derived from a precoder codebook using a low computationally complex process. A plurality of uplink channel matrix estimates are received at a Base Station (BS) from a User Equipment (UE). The plurality of uplink channel matrix estimates are processed to determine an indicator of the precoder having a highest spectral efficiency estimate. The indicator of the precoder having the highest spectral efficiency estimate is selected for transmission by the BS.
