Abstract: Embodiments of the present disclosure relate to the resource configuration for Narrow Band Internet of Thing (NB-IoT). A method of resource configuration for NB-IoT includes determining, at a network device, whether a configured Uplink Resource (PUR) for transmission from a terminal device to the network device is to be adjusted; in response to determining that the PUR is to be adjusted, determining a set of resources to be allocated for further transmission from the terminal device to the network device based on a Transport Block Size (TBS) associated with the further transmission; generating reconfiguration information of the PUR based on the set of the resources; and transmitting the reconfiguration information to the terminal device. In this way, the resource configuration may be determined and adjusted more efficiently and flexibility compared to the conventional way.

Abstract: A method includes performing, by a terminal device, a sub-bandwidth part based operation. The method includes determining a requirement for radio frequency retuning, and switching from the sub-bandwidth part based operation to a bandwidth part based operation. The method also includes performing the bandwidth part based operation.

Abstract: There is provided an apparatus, said apparatus comprising means for receiving, at a user equipment, a scheduling grant for a first number, M, of transport blocks, wherein the scheduling grant comprises an indication of a second number, N, of transport blocks to be transmitted or received before a time delay, wherein M is greater than 1 and N is less than or equal to M, causing transmission or reception of a first group of N transport blocks and, if N is less than M, after the time delay, causing transmission or reception of a further group of up to N transport blocks followed by the time delay, until M transport blocks are caused to be transmitted or received.

Abstract: The present disclosure relates to techniques that enable an efficient Radio Link Monitoring (RLM) for a User Equipment (UE) in a multi Transmitter Receiver Point (mTRP) scenario. For this purpose, a serving cell of a serving Distributed Unit (DU) of a disaggregated network node and at least one non-serving (or stand-by) cell of a non-serving DU of the disaggregated network node are configured fora UE. Then, the UE is informed of beams used for the serving and non-serving cells. The UE performs the RLM over the serving cell by using the beams of the serving cell. Whenever there is an Radio Link (RL) quality degradation (which may potentially lead to an RL Failure (RLF)) detected in the serving cell, the UE may initiate switching of the RLM from the serving cell to one of the non-serving cells by transmitting a corresponding request to the serving DU.

Abstract: Improved techniques of handover involving dual connectivity configuration with CHO include configuring a UE with a conditional fallback configuration (CFC) linked to M-RLF event at the source MN. Specifically, the MN prepares a fallback configuration along with the CHO configuration for the UE. This fallback configuration is provided to the UE as a conditional configuration, but this is not linked to measurement-event but rather to a radio link failure event. The condition is linked to MCG-RLF along with additional measurement criteria.

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: Exemplary embodiments of the present disclosure relate to a beam failure recovery to a cell. In an aspect, a first network device determines a radio resource control (RRC) reconfiguration for one or more cells prepared by the first network device. The RRC reconfiguration comprises a beam failure recovery configuration to be used by a terminal device for performing a beam failure recovery to the one or more cells. The first network device transmits, to a second network device, the RRC reconfiguration. By this process, the UE may recover to a non-serving cell in case of detecting a beam failure.

Abstract: Embodiments of the present disclosure relate to lower layer triggered mobility. In an aspect, a terminal device receives a radio resource control signaling including a transmission configuration indicator from a first network device. The transmission configuration indicator state is configured for beam-only-switching. The terminal device performs beam-only switching based on the transmission configuration indicator state and a first switching command, then configuration switching based on the first switching command or a second switching command. As such, a solution for enhanced lower layer triggered mobility is provided, thereby reducing the interruption time.
