    Abstract: A network node may determine a congestion level of a random access channel; and may transmit, to one or more energy constrained user equipments, at least one barring parameter, wherein the at least one barring parameter may be based, at least partially, on the determined congestion level and an energy constraint of the one or more user equipments. An energy constrained user equipment may receive a system information block comprising a barring factor and a back-off time; may determine whether to transmit a preamble for a random access procedure based, at least partially, on the barring factor and a maximum number of preamble transmission attempts; may transmit the preamble based on a determination to do so, or may wait for the back-off time based on a determination to not do so.

    Abstract: Embodiments of the present disclosure propose a solution for multi-interval DRX. According to embodiments of the present disclosure, a DRX method is introduced to use multiple intervals synchronized with the satellites' coverage timing. The DRX according to embodiments of the present disclosure allows the terminal device to wake up according to a set of pre-determined intervals determined by the network. The network determines the wake-up intervals based on the information on the satellite orbits (ephemeris) and the UE device information. In this way, the energy at the terminal device has been saved, thereby maximizing the battery life of the terminal device. Moreover, it also avoids the terminal device from unnecessary activation.

    Abstract: Systems, methods, apparatuses, and computer program products for access management for reduced capability (RedCap) devices. A method may include acquiring system information from a cell. In some example embodiments, the system information may provide a control resource set zero configuration. The method may also include monitoring a physical downlink control channel based on the control resource set zero configuration. The method may further include receiving, from the physical downlink control channel, downlink control information that indicates a resource allocation for a system information block. In addition, the method may include determining, from the resource allocation whether the cell is barred.

    Abstract: Systems, methods, apparatuses, and computer program products for modulation coding scheme (MCS) table extension for narrowband Internet of Things (NB-IoT). The method may include receiving at a user equipment, downlink control information from a network node comprising a modulation and coding scheme field and a repetition number field. The method may also include reading the modulation and coding scheme field and the repetition number field. The method may further include determining a modulation and coding scheme value and a repetition number based on an indication in the modulation and coding scheme field. In addition, the method may include setting a transmission block size index value based on the determination.

    Abstract: At a UE configured with an idle-mode configuration for using a PUR, determining that data not associated with the PUR is to be transmitted or received via an RRC connection. The UE performs an initial access to a network for the radio resource control connection. The UE transitions from RRC idle mode to RRC connected mode. The UE performs one of suspending the idle-mode configuration or maintaining the idle-mode configuration, for at least a duration of the RRC connected mode. A base station received the initial access, determines the UE is configured with the idle-mode configuration for using a PUR and transitions the UE from RRC idle mode to RRC connected mode. The base station performs communication between the base station and the UE to perform action(s) to modify one or both of the idle-mode configuration or an RRC connection corresponding to the transition into the RRC connected mode.
