Abstract: Embodiments of the present disclosure relate to devices, methods, apparatuses and computer readable storage media of link adaptation with unlicensed channel access of CG PUSCH. The method comprises receiving, at a first device and from a second device, a configuration of at least two candidate resources for a transmission from the first device to the second device, selecting, from the at least two candidate resources, a target resource for the transmission based on an availability of a channel occupancy time, COT, initiated by the second device for the transmission, and performing the transmission based on the selected target resource. This solution facilitates low latency CG PUSCH operation, where channel access probability can be improved by Tx power adjustment when needed, by allowing the UE to select the most appropriate CG-PUSCH resource. In this way, the use of CG PUSCH resources may be more effective and the UE operation and the gNB detection can also be simplified.

Abstract: The present disclosure relates to a simple and power-efficient procedure that allows using wake-up signaling in inter-cell mobility scenarios. The procedure is based on configuring a Wake-Up Signal (WUS) Beacon Occasion (WBO) for each Tracking Area (TA) of a user device. A WUS beacon corresponding to each cell in the TA is transmitted once at a cell-specific time offset within the WBO. The WBO is configured together with a mapping table that maps each of the cell-specific time offsets to cell-specific information. The cell-specific information may comprise a cell ID and/or an indicator of a cell-specific frequency and/or cell-specific frequency range to be used for synchronization signal reception (e.g., Global Synchronization Channel Number (GSCN)). Each TA comprises intra-frequency cells only. By using the WBO, the user device may reduce its power consumption by avoiding switching from its sleep state to its active state when doing cell reselections in the TA.
