umber which satisfies the following equation [20]: where symbol slot , Ms, and toffset denote the number of symbols per slot, symbol number in the slot, and the time domain offset, respectively. Similarly, subsequent to an uplink grant set up for a configured grant Type 2, the MAC entity considers the time-domain location of the Nth uplink grant-free transmission at the symbol for which the following criterion is satis- fied [20]: sFa slot start-time AN 20 where SFNstart-time, Tslot symbol start-time' start-time represent the SFN, slot, and symbol where the first transmission of PUSCH with the configured uplink grant was initialized, respectively. When a configured grant is released by upper layers, all corresponding configurations are cleared. Retransmissions except for repetition of the configured grants use uplink grants with CS-RNTI. In summary, in the downlink, the gNB can allocate downlink resources for the initial HARQ transmissions to UEs with semi-persistent scheduling. The RRC signaling defines the periodicity of the configured downlink assignments while PDCCH addressed with New Radio Access Physical Layer Aspects (Part 1) 407 CS-RNTI can either signal and activate the configured downlink assignment, or deactivate it, that is, a PDCCH scrambled with CS-RNTI indicates that the downlink assignment can be implicitly reused according to the periodicity defined by RRC, until deactivated. In the uplink, the gNB can allocate uplink resources for the initial HARQ transmissions to UEs with configured uplink grants. Two types of configured uplink grants are defined: Type 1, where RRC directly provides the configured uplink grant (including the periodicity) and Type 2, where RRC defines the periodicity of the configured uplink grant while PDCCH addressed to CS-RNTI can either signal and activate the configured uplink grant, or deacti- vate it, that is, a PDCCH addressed with CS-RNTI indicates that the uplink grant can be implicitly reused according to the periodicity defined by RRC, until deactivated [19].
