  • There may be different types of scheduling for example, dynamic scheduling, semi-persistent scheduling (SPS) and the like.
  • SPS semi-persistent scheduling
  • a terminal device can get scheduling assignments/grants in every subframe. This gives a network full flexibility in assigning resources to the terminal device at the cost of transmission of resource allocation information on physical downlink control channel (PDCCH) in every subframe. This also gives the flexibility of varying the resource allocation based on reported channel conditions.
  • SPS can be configured only in the uplink, or in the downlink (sps-ConfigDL) or in both directions. Configuration of SPS doesn’ t mean that the terminal device can start using SPS grants/assignments.

Further, the network device can explicitly release SPS without release SPS RRC configuration. Moreover, a feedback mechanism is also supported at the terminal device. In order to reduce feedback latency, a sub-slot based feedback has been introduced.
