Abstract: The present disclosure relates generally to the field of wireless communications, and in particular to techniques for performing one-step data transmissions from a User Equipment (UE) to a Base Station (BS), without requiring the UE to transit from an idle state to a connected state in a wireless communication network. To make it possible to perform the one-step data transmission, the UE receives a confirmation from the BS that the BS supports the one-step data transmission (which means that the BS has allocated, in advance, the UL resources for performing the one-step data transmission), and to have a pre-stored database associating cell IDs of different cells with corresponding pre-allocated UL resources and transmission parameters. Said confirmation from the BS may be represented by a predefined signal sequence, the presence of which will inform the UE about the possibility of performing the one-step data transmission within a cell of interest. After receiving the predefined signal sequence, the UE uses the pre-stored database to find the UL resources and transmission parameters used for the one-step data transmission from the idle state within the cell of interest.

Abstract: In accordance with example embodiments of the invention there is at least a method and apparatus to perform determining a first set of candidate single-slot resources for a physical sidelink shared channel transmission by a first user equipment; determining a second set of candidate multi-slot resources for the physical sidelink shared channel transmission by the first user equipment; and reporting at least one candidate single-slot resource from the first set and at least one candidate multi-slot resource from the second set to a higher layer for resource selection. Further, to perform determining a union set by forming a union of the first set and the second set; determining a subset of the union set by excluding a candidate resource at least based on whether the candidate resource overlaps with a resource reserved for transmission by a second user equipment; and reporting the determined subset to the higher layer for resource selection.

Abstract: According to an aspect, there is provided an apparatus configured to perform the following. The apparatus establishes itself as a timing source terminal device for sidelink communication and estimates a first time uncertainty caused by the apparatus for sidelink communication. Then, the apparatus causes transmission of information on at least one of the first time uncertainty and a combined time uncertainty to one or more target terminal devices. The combined time uncertainty corresponds to a combination of the first time uncertainty and a second time uncertainty. The second time uncertainty corresponds to a time uncertainty of reference time defined in reference time information.

Abstract: An apparatus including at least one processor and at least one memory including computer program code. The at least one memory and the computer program code configured, with the at least one processor, to cause the apparatus at least to receive, from a serving access node, a downlink radio resource control message including reference time information for a clock provided by the serving access node and traceability information for enabling traceability of the clock to a reference time standard. The traceability information includes at least information on a clock class indicative of a current status of the clock provided by the serving access node.

Abstract: A method, apparatus, and a computer-readable storage medium are provided for constructing a HARQ-ACK codebook for managing the trade-off between codebook size and feedback granularity. In an example implementation, the method may include a network node determining a second time domain resource allocation table and transmitting configuration information to the UE. The method may further include the network node transmitting downlink data to the UE and receiving the one or more ACKs and/or NACKs from the UE in response to the transmitting of the downlink data, the one or more ACKs/NACKs being generated based at least on the second time resource allocation table. In another example implementation, the method may include a user equipment (UE) receiving configuration information from a network node, receiving downlink data from the network node, and transmitting one or more ACKs/NACKs to the network node.
