Abstract
Aspects relate to mechanisms for mutual information (MI)-based physical downlink control channel (PDCCH) candidate pruning. A UE may receive a plurality of PDCCH candidates in a search space. Each of the PDCCH candidates includes a demodulation reference signal (DMRS) generated with the same scrambling seed and control information generated with one or more respective UE-specific non-transparent precoding parameters. The UE can prune the PDCCH candidates to identify at least one PDCCH candidate for decoding by generating the log-likelihood ratio (LLR) magnitudes of demodulated PDCCH candidates and calculating the mutual information based on the LLR magnitudes.
