PDSCH (LTE)

PDSCH Physical Downlink Shared Channel is the Physical Downlink Shared Channel. This is the downlink data channel for users.

When RB Auto Detect is selected and RB Auto Detect Mode is set to Power Based, the demodulator groups resource blocks by modulation type and shows three groups (PDSCH_QPSK, PDSCH_QAM16, and PDSCH_QAM64) on the Frame Summary trace.

When RB Auto Detect is selected, and RB Auto Detect Mode is set to Decode PDCCH, the demodulator decodes the allocations defined in the PDCCHs and shows each PDSCH allocation (PDSCH_User<number>) on the Frame Summary trace in increasing order of RNTI Radio Network Temporary Identifier.

When RB Auto Detect is cleared, Frame Summary shows a PDSCH allocation (PDSCH_User<number>) for each user mapping defined in the LTE Allocation Editor.

For downlink signals, auto detection supports only PDSCH allocations transmitted on C-RS Cell-specific RS antenna ports.

A PDSCH allocation can contain a combination of QPSK Quadrature phase shift keying, 16QAM, or 64QAM signals.
