http://acronymsandslang.com/definition/176094/PDSCH-meaning.html SpletOne or two transport coded blocks (codewords) can be transmitted simultaneously on the PDSCH depending on the transmission scheme used (see TS 36.211 section 6.4 [ 2 ]). As shown in figure 2 above, the codewords undergo scrambling, modulation, layer mapping, precoding, optional UE-specific beamforming and resource element mapping.

SpletScramble the contents of two codewords using the PDSCH scrambling sequence. When transmitting multiple codewords via spatial multiplexing, each codeword uses a different … SpletThe message from PDSCH channel has to be transmitted. The channel processing steps which are carried out by the PDSCH transmitter blocks are transport block, CRC, LDPC, code block segmentation, and receiver part blocks are code block concatenation, scrambling and modulation mapping blocks achieves increased in speed, high bandwidth and efficiency.

SpletFor example, payload scrambling for PDCCH scheduling MBS PDSCH may be based on URNTI = 0 if the PDCCH scheduling MBS PDSCH is a DCI format 1 0 and based on HRNTI … SpletThe symbol allocation of PDSCH indicates the OFDM symbol locations used by the PDSCH transmission in a slot. DM-RS symbol locations lie within the PDSCH symbol allocation. The positions of DM-RS OFDM symbols depend on the mapping type. The mapping type of PDSCH is either slot-wise (type A) or non-slot-wise (type B).
