Abstract: A UE performs first control channel monitoring according to a first CORESET and first search space set configuration(s), the first control channel monitoring performed on n subbands, n>1, able to be transmitted by a base station in an unlicensed band carrier. The UE determines, in response to a detection of a control channel in the monitoring and from the control channel, transmission bandwidth configuration to be used by the base station in the unlicensed band carrier for control channels. The UE performs second control channel monitoring according to a second CORESET and at least one second search space set configuration. The second control channel monitoring is performed on m subbands, m≤n, in the unlicensed band carrier, the m subbands being a subset of the n of subbands. A base station determines which subbands are available for use and transmits the transmission bandwidth configuration to the UE based thereon.

Abstract: Various communication systems may benefit from improved signaling. For example, it may be helpful to improve the management of the uplink timing alignment where multiple numerologies are used. A method may include receiving at a user equipment an indication from a network node. The timing adjustment granularity may be determined implicitly based on one or more multiple numerology assigned to a timing advance group. The method may also include applying at the user equipment the indicated timing adjustment granularity associated with one of the multiple numerologies.

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.
