Abstract: A base station, in communication with a UE using a first serving cell, determines a need to perform a security update for the UE and sends a command including information to perform the security update and indication of a time to execute the security update to change to a new security configuration. In response to the time occurring, a security update is performed to a new security configuration for use for communication with the UE using a second serving cell. The UE receives the information and the indication and performs, without performing a random-access procedure, the security update to the new security configuration to use for communication with the second serving cell.

Abstract: This disclosure presents solutions for a communication system of a non-terrestrial network (NTN) node and a user equipment (UE) to determine, where the NTN node can determine one or more HARQ retransmission schemes for one or more LCHs used by the UE. The HARQ retransmission scheme can be mapped into one, two, or five bits of the DCI signal, depending on the mapping algorithm selected. In some example embodiments. LCHs can be grouped by using similar LCH prioritization or similar HARQ retransmission schemes. HARQ retransmission schemes can be mapped to the LCG. If there remains sufficient data space in the TBS/UL, other LCH can be included into the transmission even though the other LCH utilize different HARQ retransmission schemes. The UE can encode its HARQ transmission using the HARQ retransmission scheme indicated for the LCH the UE is utilizing.

Abstract: This disclosure presents solutions for a IoT/eMTC over NTN communication system of a non-terrestrial network (NTN) node and a user equipment (UE) to determine whether and how scheduling information can be sent in the resources for a HARQ feedback, when the HARQ feedback is disabled. In some example embodiments, the UE can signal a buffer size. e.g., buffer status, by encoding the HARQ feedback and scheduling request (SR) utilizing two bits to provide the fast scheduling information. The NTN node can specify to the UE a set of HARQ parameters to provide an indication of HARQ feedback status, which can be disabling or enabling of HARQ feedback, and to provide an indication of the resources for transmission of HARQ feedback when the indication of HARQ feedback status is disabling.

Abstract: Embodiments of the present disclosure propose a solution for availability of system broadcasted information such as GNSS information which can be used for deriving time and/or frequency domain compensation. According to embodiments of this present disclosure, a validity timer for system broadcasted information is introduced in both UE and network to guarantee the system broadcasted information availability status is synchronized in two nodes, and the system broadcasted information is valid to pre-compensate in time and/or frequency domain when the timer is running. In this way, the UE can be scheduled with correct timing and frequency estimation in UL transmission.

Abstract: According to embodiments of the present disclosure, service-based retransmission scheme for uplink in NTN has been proposed, which can support multiple retransmission schemes based on service type for uplink. The network device determines different retransmission schemes based on the QoS requirements of the services. The terminal device selects the retransmission scheme for the service. In this way, the QoS of different service and reliability of MAC CE can be guaranteed.

Abstract: Example embodiments of the present disclosure relate to a solution for transmitting or receiving segments of information. In an aspect, a first device generates a plurality of messages to be transmitted to a second device. Each of the plurality of messages comprises a segment of information to be provided to the second device. The first device transmits a part of the plurality of messages to the second device. In response to the first device being triggered to perform an operation with a higher priority than the transmission of the plurality of messages, the first device performs the operation by interrupting the transmission of rest of the plurality of messages to be transmitted. With example embodiments of the present disclosure, it is enabled that transmission of messages conveying information segments may be interrupted to perform an operation with a higher priority.

Abstract: Embodiments of the present disclosure relate to supporting network controlled measurement interruption ratio. In an aspect, a terminal device determines, based on at least one measurement requirement, a first interruption ratio. The first interruption ratio is different from a second interruption ratio acceptable by the network device. The terminal device transmits, to a network device, a first message requesting the network device to grant the first interruption ratio. By implementing the embodiments of the present disclosure, network controlled measurement interruption ratio can be supported and the negative impact caused by the interruptions could be reduced.

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: Embodiments of the present disclosure relate to methods, devices, apparatuses, and computer readable medium of enhancements on uplink transmission. The method comprises: transmitting, to a second device, a first group of transmission repetitions based on first uplink synchronization information: prior to transmitting a second group of transmission repetitions, determining second uplink synchronization information based on system broadcast information for deriving transmission compensation in at least one of time domain and frequency domain; and transmitting, to the second device and based on the second uplink synchronization information, the second group of transmission repetitions. The method helps guarantee the effective receipt of uplink repetitions with compensation jump in time or frequency domain or update due to changing of uplink synchronization information. In addition, the network knows how to combine or select repetitions for best performance when the UE automatically adjusts the UL compensation in time or frequency domain during the repetitions.
