Abstract: Systems, methods, and devices are provided for performing cell selection or reselection in networks that include earth moving beams. In one example, a method includes receiving, via a satellite, control information transmitted by a base station indicating that a beam associated with a cell ID has been redirected; in response, measuring a beam strength of the redirected beam; and performing cell re-selection based on the measured beam strength.

IPC: H04W36/00
Abstract: A user equipment (UE) is configured to operate as a relay UE between a remote UE and a base station. The relay UE receives, from an originating device, a data packet for relay to a recipient device, determines that the relay of the data packet to the recipient device has failed and sends, to the originating device, a transmiss ion including the data packet, wherein the transmission comprises an indication that the data packet is being returned to the originating device.

Abstract: This disclosure relates to performing implicit radio resource control state transitions in a cellular communication system. A wireless device may establish a radio resource control (RRC) connection with a cellular base station. A data inactivity timer length and a target RRC state for implicit RRC transitions may be determined. A data inactivity timer having the determined data inactivity timer length may be initiated. It may be determined that the data inactivity timer has expired. The wireless device may transition to the target RRC state based at least in part on determining that the data inactivity timer has expired.

IPC: H04W68/08
Abstract: Techniques discussed herein may enable effective cell identification and paging within a non-terrestrial network (NTN). A base station may map logical cell identifiers, corresponding to satellites, to physical cell identifiers, corresponding to physical or geographic cells. The techniques enable cell identification and paging in both Earth-fixed cell scenarios and Earth-moving cell scenarios, and in scenarios where the satellite moves between countries.

IPC: H04W36/08
Abstract: Techniques discussed herein facilitate cell selection and/or reselection in scenarios involving one or more Non-Terrestrial Network (NTN) cells. One example embodiment is a User Equipment (UE) device comprising a processor configured to perform operations comprising: determining one or more suitable cells for one of a cell selection procedure or a cell re-selection procedure, wherein the one or more suitable cells comprise a first cell associated with a satellite of a NTN; determining a ranking for each cell of the one or more suitable cells, wherein the ranking for the first cell is based at least in part on a location of the UE, ephemeris data of the satellite, and one or more additional parameters; selecting a highest ranked cell of the one or more suitable cells based on the determined rankings for each cell of the one or more suitable cells; and camping on the highest ranked cell.

Abstract: This disclosure relates to techniques for performing paging forwarding for remote wireless devices in a wireless communication system. A relay wireless device and a remote wireless device may establish a relay link. The relay wireless device may provide an indication of the relay link between the relay wireless device and the remote wireless device to a cellular base station. The relay wireless device may receive paging information for the remote wireless device from the cellular base station. The relay wireless device may provide the paging information to the remote wireless device via the relay link between the relay wireless device and the remote wireless device.
