摘要
A method of enabling an Open RAN-compatible radio unit (O-RU) to apply different beamforming weights to different physical resource blocks (PRBs) using a single sectionId and a single section extension type includes: specifying a first mode of operation in which the number of beamforming weights in the section extension type 1 is equal to L*numPrbs, L is the number of TRX and numPrbs is the number of physical resource blocks; signaling, by an Open RAN-compatible distributed unit (O-DU) to the O-RU, the first mode of operation by specifying a value of parameter extLen to be zero, wherein extLen is the length of the section extension in units of 32-bit words; and the O-RU applying the kth beamforming weights (bfwI and bfwQ), k=1, 2, . . . , L*numPrbc in section extension type 1 for TRX j, j=0, 1, . . . , L−1 to the ith PRB, i=1,2, . . . , numPrbc defined under the sectionId of the C-plane message.
