re Nslot frame denotes the number of slots per frame Nslot is the slot number in the frame, TSPS denotes the SPS period, SFNstart-time and Tslot start-time represent the SFN and slot of the first transmission of PDSCH where the configured downlink assignment was initialized, respectively [20]. In the uplink direction, there are two types of transmission without dynamic grant known as configured grant Type 1, where an uplink grant is provided by RRC, and stored as config- ured uplink grant; and configured grant Type 2, where an uplink grant is provided by PDCCH and stored or cleared as configured uplink grant based on physical layer signaling 406 Chapter 3 indicating configured grant activation or deactivation. Both Type 1 and Type 2 grants are configured by RRC per serving cell and per BWP. Multiple configurations can be active simultaneously on different serving cells. For Type 2 grant, activation and deactivation are independent among the serving cells. When the configured grant Type 1 is used, the RRC configures the following parameters: a CS-RNTI for retransmission; periodicity of the con- figured grant Type 1; the offset of a resource with respect to SFN = 0 in time domain; time-domain parameters which include the start symbol and the length of the assignment; as well as the number of HARQ processes [20]. Alternatively, when the configured grant Type 2 is going to be used, the RRC configures the following parameters: a CS-RNTI for activa- tion, deactivation, and retransmission; the periodicity of the configured grant Type 2; and the number of HARQ processes. Once a configured grant Type 1 semi-persistent allocation is set up in a serving cell by upper layers, the corresponding MAC entity stores the uplink grant provided by upper layers and initializes the configured uplink grant to start in the sym- bol according to the provided parameters. After an uplink grant is set up for a configured grant Type 1 uplink transmission, the MAC entity considers the Nth uplink transmit opportu- nity to occur in the symbol n
