1. A method, comprising:
sending, by a base station to a wireless communication device, a first number of Transmitted Precoding Matrix Indicators (TPMI) codewords that maps to a second number of codebook-based uplink transmission repetitions of the wireless communication device, the first number being greater than 1, the second number being greater than 1; and
receiving, by the base station from the wireless communication device, the codebook-based uplink transmission repetitions transmitted based on the TPMI codewords,
wherein the base station sends the TPMI codewords in Downlink Control Information (DCI), the DCI comprising a first field containing a value for the first TPMI codeword and a second field containing a value for the second TPMI codeword, and
wherein:
the second field corresponds to a plurality of tables;
the plurality of tables correspond to different antenna attributes of the wireless communication device;
the antenna attributes comprise one of non-coherent, partially coherent, or fully coherent; and
the second TPMI codeword corresponds to the antenna attributes of the wireless communication device.
