Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses, and computer readable storage media of access resource selection for Small Data Transmission (SDT). The method comprises determining one or more resources used for a mobile terminated type SDT procedure; and performing the mobile terminated type SDT procedure to a second device based on the determined one or more resources. In this way, separate resources can be configured for mobile originated SDT (MO-SDT) and mobile terminated SDT (MT-SDT). It is beneficial considering the MO-SDT and MT-SDT might have different assumption/thresholds of UL data available for transmission and Reference Signal Received Power (RSRP) threshold, hence impact the network response or further scheduling.

Abstract: Embodiments of the present disclosure provide a method and an apparatus for determining a transmission resource for initiating a data transmission. The method (100) performed by a terminal device may comprise: acquiring (S102) a time limit for determining whether a configured transmission resource is within the time limit; and initiating (S104), based on the transmission resource being within the time limit and being valid for a data transmission, the data transmission using the transmission resource in an inactive state. According to embodiments of the present disclosure, the time limit is considered for determining the transmission resource, and thus the data transmission can be performed timely.

Abstract: Example embodiments of the present disclosure relate to random access to a secondary cell (SCell). A first device receives, from a second device, configuration information indicating first resources for the first device to perform a random access to a secondary cell of the first device. Radio network temporary identifiers corresponding to the first resources are different from radio network temporary identifiers corresponding to second resources configured for a random access to a primary cell of the first device. The first device selects a resource from the first resources and transmits, to the second device via the secondary cell, a random access request by using the selected resource.

Abstract: Example embodiments generally relate to devices and methods for remapping of paging subgroups. A user equipment (UE) device may be configured to receive from a base station an explicit or implicit indication of remapping between one or more first scheme paging subgroups and one or more L1 paging subgroups, remap a first scheme paging subgroup of the UE device to a L1 paging subgroup based on the received indication of remapping, monitor for a paging early indication (PEI) from the base station including an indication of the remapped L1 paging subgroup, and receive a paging message from the base station based on the PEI.

Abstract: Embodiments of the present disclosure relate to handling data during SDT. A first device in an inactive state performs an initial transmission to a second device during an SDT. The first device receives. from the second device. data subsequent to the initial transmission during the SDT. The first device buffers the data. The first device handles the buffered data in accordance with a determination that security verification is successful.

Abstract: Embodiments of the present disclosure relate to reporting beam failure. A terminal device detects a beam failure on one or more serving cells of the terminal device. If the beam failure is detected on the one or more serving cells, the terminal device obtains information concerning one or more candidate beams and the one or more serving cells. Each of the one or more candidate beams is associated with a respective one of the one or more serving cells. The terminal device then transmits at least a portion of the information to a network device associated with the one or more serving cells.

Abstract: Example embodiments of the present disclosure relate to initiation of small data transmission (SDT). A first device determines whether SDT is allowed to be initiated at a first protocol layer of the first device. In accordance with a determination that the SDT is allowed to be initiated at the first protocol layer, the first device determines whether the SDT is allowed to be initiated at a second protocol layer of the first device. In accordance with a determination that the SDT is allowed to be initiated at the second protocol layer, the first device initiates, via the first protocol layer, a communication procedure for the SDT with a second device. Through this solution, it is possible to avoid unnecessary interactions between protocol layers as well as avoid false resume of the radio bearer when the SDT procedure cannot be performed.
