addressed to a UE using its CS-RNTI indicates that the downlink assignment can be implic- itly reused according to the periodicity defined by the RRC signaling, until deactivated. When a configured downlink assignment is active, if the UE cannot find its C-RNTI on the PDCCH(s), a downlink transmission according to the configured downlink assignment is assumed; otherwise, if the UE finds its C-RNTI on the PDCCH(s), the PDCCH allocation overrides the configured downlink assignment. When carrier aggregation is configured, one configured downlink assignment can be signaled per serving cell. When bandwidth New Radio Access Physical Layer Aspects (Part 2) 477 adaptation is configured, one configured downlink assignment can be signaled per BWP. On each serving cell, there can be only one configured downlink assignment active at a time, and multiple configured downlink assignment can be simultaneously active on differ- ent serving cells. Activation and deactivation of configured downlink assignments are inde- pendent among the serving cells [11]. In the uplink, the gNB can dynamically allocate resources to the UEs by scrambling their respective C-RNTI with PDCCH(s) CRCs. A UE always monitors the PDCCH(s) in order to find possible grants for uplink transmission when its downlink reception is enabled where the activity is synchronized with the UE DRX cycles. When carrier aggregation is config- ured, the same C-RNTI applies to all serving cells. In addition, with configured grants, the gNB can allocate uplink resources for the initial HARQ transmissions to the UEs. Two types of configured uplink grants are defined in NR: Type 1, where the RRC signaling directly provides the configured uplink grant (including the periodicity); and Type 2, where the RRC signaling defines the periodicity of the configured uplink grant while PDCCH addressed to the UE using its CS-RNTI can either signal and activate the configured uplink grant, or deac- tivate it, that is, a PDCCH addressed to the UE using its CS-RNTI would indicate that the upl
