Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of energy harvesting information supported User Equipment (UE) scheduling. The method includes reporting, to a network device in the radio network, energy harvesting capability of the terminal device indicating a first energy value (ΔEt) collected during a first time interval (Δt) and a second energy value (EAvg) averaged over a second time interval; and communicating with the network device to transmit data according to scheduling information received from the network device and determined based on the energy harvesting capability of the terminal device. In this way, the terminal device may be scheduled by the network based on its energy harvesting capability, to maintain a trade-off between harvested energy utilization and fairness in scheduling from Passive IoT UEs.

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: This disclosure presents methods to compensate for a phase drift in an uplink communication signal between a user equipment (UE) and a non-terrestrial network (NTN) node. Due to the change rate of velocity of the UE relative to the NTN node, a transmission signal can drift causing demodulation errors at the receiver. The UE can apply compensation processes to the transmission signal so that the received signal is closer to the original transmitted signal as compared to a non-compensated signal. Alternatively, the NTN node can apply compensation process to modify the reference phase to be closer to the phase of the received signal in the demodulation process. The location of the UE, as well as its relative elevation, can be used with the NTN node's location, to generate the compensation information. The compensation can be applied on a symbol-by-symbol basis or to a group of M symbols.

Abstract: Systems, methods, apparatuses, and computer program products for power state transition handling for energy harvesting aware user equipment are provided. For example, a method can include sending, by a user equipment, a message to a network indicating either a power state transition or non-transition. The power state transition can correspond to the user equipment transitioning from a first power state to a second power state based on an available energy of the user equipment. The method can also include receiving, by the user equipment, an information message from the network in accordance with the power state transition.

Abstract: A reconfigurable intelligent surface (RIS) in a radio network includes a plurality of passive elements which are controlled by a plurality of active elements distributed among the plurality of passive elements, wherein the plurality of active elements configure the reconfigurable intelligent surface to perform, based on at least one request message, at least one of sensing incident electromagnetic radiation harvested over at least one frequency range by the passive elements; and steering energy of the harvested electromagnetic radiation towards at least one energy harvesting device in the radio network. A network node is configured to select at least one reconfigurable intelligent surface in a radio network; and send at least one request message to the selected reconfigurable intelligent surface to cause the reconfigurable intelligent surface to steer harvested electromagnetic radiation within at least one frequency range toward at least one energy harvesting device in the radio network.

Abstract: Systems, methods, apparatuses, and computer program products for switching beams on/off for high altitude platform stations (HAPS) are provided. One method may include selecting a beam on/off pattern from one or more beam on/off patterns for a high altitude platform station (HAPS) and a rotation period for the beam on/off pattern, based at least on flight information of the high altitude platform station (HAPS) and user equipment (UE) traffic load information. The method may also include transmitting, to one or more user equipment (UEs), an indication of beam switching on/off operation comprising at least one of the selected beam on/off pattern, a pattern rotation speed, and a reference time slot for a start of the selected beam on/off pattern. The method may then include initiating the beam switching on/off operation.

Abstract: Systems, methods, apparatuses, and computer program products for network-assisted signaling for uplink digital pre-distortion (DPD). A gNB may use an uplink reference signal (RS) to measure a user equipment's (UE's) power amplifier (PA) nonlinearity, where the UE may transmit its UE-specific RS with maximum transmit (Tx) power at a PA measurement window in the uplink. The gNB may train an artificial intelligence-based model to approximate the pre-distortion function (with PA parameters). The gNB may signal DPD-related information, and the UE may determine (and adjust) its DPD function based on the gNB signalling.
