Enhanced downlink semi-persistent scheduling (SPS)

A non-transitory computer-readable storage medium that stores instructions for execution by one or more processors of a next generation Node-B (gNB), the instructions to configure the gNB for downlink (DL) semi-persistent scheduling (SPS) communications in a New Radio (NR) network, and to cause the gNB to:

• encode higher layer signaling, the higher layer signaling to indicate a downlink SPS configuration, the DL SPS configuration including a periodicity and a number of repetitions of physical downlink shared channel (PDSCH) transmissions, the number of repetitions indicated by a PDSCH Aggregation Factor included within the DL SPS configuration, the PDSCH Aggregation Factor within the DL SPS configuration being different from a PDSCH Aggregation Factor within a PDSCH configuration communicated via the higher layer signaling;
• encode a downlink control information (DCI) format for transmission via a physical downlink control channel (PDCCH), the DCI format activating the DL SPS configuration for the PDSCH transmissions;
• and
• encode the PDSCH transmissions across multiple consecutive slots based on the periodicity and the number of repetitions.

A system of a user equipment (UE), the system comprising:

• at least two antennas;
• front-end circuitry coupled to the at least two antennas;
• and
• baseband processing circuitry coupled to the front-end circuitry, wherein to configure the UE for downlink (DL) semi-persistent scheduling (SPS) in a New Radio (NR) network, the baseband processing circuitry is to:
• decode higher layer signaling received via the at least two antennas, the higher layer signaling to indicate a downlink SPS configuration, the DL SPS configuration including a periodicity and a number of repetitions of physical downlink shared channel (PDSCH) transmissions, the number of repetitions indicated by a PDSCH Aggregation Factor included within the DL SPS configuration, the PDSCH Aggregation Factor within the DL SPS configuration being different from a PDSCH Aggregation Factor within a PDSCH configuration received via the higher layer signaling;
• decode a downlink control information (DCI) format received via a physical downlink control channel (PDCCH), the DCI format activating the DL SPS configuration for the PDSCH transmissions;
• detect using the periodicity and the number of repetitions for the DL SPS, the PDSCH transmissions across multiple consecutive slots based on the DCI format activating the DL SPS configuration;
• and
• decode the PDSCH transmissions across the multiple consecutive slots.
