16. A method for identifying a released semi-persistently scheduled (SPS) physical downlink shared channel (PDSCH) with aggregation factor (AF), the method comprising:
identifying, by a PDSCH manager of a base station comprising a processor and memory, a timing of an ending symbol of a last repetition of the released SPS PDSCH with AF in a scheduled cell;
identifying, by the PDSCH manager, a timing of an ending symbol of a SPS release physical downlink control channel (PDCCH) in a scheduling cell;
comparing, by the PDSCH manager, the timing of the ending symbol of the SPS release PDCCH and the timing of the ending symbol of the last repetition of the released SPS PDSCH with AF; and
releasing, by the PDSCH manager, the released SPS PDSCH with AF based on determining that the ending symbol of the SPS release PDCCH is before the ending symbol of the last repetition of the released SPS PDSCH with AF.
