Abstract: A base station configures a Physical Downlink Control Channel (PDCCH) for transmission to one or more user equipments (UEs). The base station divides a component carrier (CC) bandwidth into a plurality of sub-bands, transmits a physical random access channel (PRACH) resource on at least one of the sub-bands and transmits a Type1-PDCCH CSS (Physical Downlink Control Channel Common Search Space) set on at least one of the sub-bands, wherein the Type1-PDCCH CSS set corresponds to the PRACH resource.

Abstract: A base station (BS) comprising a processor configured to perform operations is described. In an exemplary embodiment, the operations include receiving an initial data from a UE is in a RRC_INACTIVE while the UE does not transition from the RRC_INACTIVE state to a RRC_CONNECTED state. In addition, the operations include transmitting a physical downlink control channel (PDCCH) for a UE dedicated scheduling for a transmission or reception of a subsequent data during an active period, while the UE is in the RRC INACTIVE state. Furthermore, the operations include receiving or transmitting the subsequent data transmission based on the dedicated scheduling. The operations additionally include transmitting one or more configurations for the transmission or reception of the subsequent data. The one or more configurations is transmitted as part of the RRC release message. The one or more configurations is transmitted as part of a System Information Block (SIB).

Abstract: A base station (BS) comprising a processor configured to perform operations is described. In an exemplary embodiment, the operations include generating one or more pre-configured grant (pre-CG) configurations. The operations also include transmitting the one or more pre-CG configurations to a user equipment (UE) to enable the UE to perform an initial transmission while the UE is in an RRC_INACTIVE state using a pre-CG resource based on the transmitted one or more pre-CG configurations. Each of the one or more pre-CG configurations includes a configuration of the pre-CG resource and one or more conditions to use the pre-CG resource. The one or more conditions to use the pre-CG resource include one or more of an access type, a transmission priority, a mapped Logical Channel (LCH) /Dedicated Radio Bearer (DRB) /Quality of Service (QoS) flow, and a valid timing advance (TA).

Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing sidelink communications among multiple user equipments (UEs). A UE operates according to a periodical discontinuous reception (DRX) cycle that includes a sidelink on-duration period when the UE is in an active state. The UE is in a power saving state outside the sidelink on-duration period. The UE listens to a Physical Sidelink Control Channel (PSCCH) for sidelink communications during the active state. A UE determines the DRX cycle and the sidelink on-duration period of a receiver UE, and sends a message to the receiver UE during one or more slots of the sidelink on-duration period when the receiver UE is in the active state.
