Abstract: Method and device in nodes used for wireless communications. A node receives first information, the first information being used to determine X candidate formats; transmits a first signal, the first signal using a first format; and transmits a second signal, the second signal using a second format; the first format is one of the X candidate formats, and the second format is also one of the X candidate formats; a first timing offset value is used to determine a transmission timing for the first signal, while a second timing offset value is used to determine a transmission timing for the second signal, where the first timing offset value is unequal to the second timing offset value; the first format relates to the first timing offset value while the second format relates to the second timing offset value. The present disclosure improves the random access performance.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may measure a parameter associated with a secondary cell group. The UE may perform an optimization response action for a dual connectivity mode of a first frequency parameter or a second frequency parameter when the parameter satisfies a threshold, wherein the optimization response action is associated with whether the secondary cell group is operating with the first frequency parameter or the second frequency parameter. Numerous other aspects are described.

Abstract: Apparatuses, systems, and methods for enhancement in NTN mobility. A cellular base station may serve as a source base station of a handover procedure from the source base station to a target non-terrestrial network (NTN) base station. The cellular base station may configure a parameter associated with the target NTN base station in a handover command, the parameter being related to NTN mobility, and send the handover command to a wireless device for use by the wireless device during the handover procedure. The wireless device may receive the handover command from the cellular base station, and perform the handover procedure using the parameter associated with the target NTN base station.

Abstract: Methods and apparatuses in a wireless communication system. A method of a UE comprises: receiving, from a base station (BS) in a non-terrestrial network (NTN), a system information block (SIB); determining that the SIB includes first neighboring cell information and first timing information associated therewith; determining that a first neighboring cell is not a candidate cell for a cell selection or re-selection operation when a current time is before or equal to a time indicated by the first timing information; and determining that the first neighboring cell is a candidate cell for the cell selection or re-selection operation when the current time is after the time indicated by the first timing information.

Abstract: A method (600) performed by a Steering of Roaming Application Function, SOR-AF. The method includes receiving a roaming status reporting notify message from a Unified Data Management, UDM. The notify message comprises roaming status reporting information including a new serving Public Land Mobile Network, PLMN, Identifier, an access type of a User Equipment for accessing the new serving PLMN identified by the PLMN Id, and a roaming indication indicating the new serving PLMN is different from the Home PLMN or not. The method further includes generating an updated steering of roaming information based on the received roaming status reporting information including at least the access type; and transmitting to the UDM a parameter provision update request message. The update request message comprises the updated steering of roaming information.

Abstract: The invention relates to an improved handover procedure for a mobile terminal. Under control of the target base station, the mobile terminal is to perform a handoff to a target base station, wherein it is to be configured for communication with the target base station via a target radio cell comprising a downlink carrier and an uplink carrier. The mobile terminal receives a handoff command message for the handoff to the target base station including a handoff execution condition as trigger for executing handoff to the target base station. Then, the mobile terminal determines, based on the received handoff execution condition, whether or not the mobile terminal is to trigger execution of the handoff to the target base station. In case the mobile terminal determines that it is to trigger execution of the handoff to the target base station, the mobile terminal executes the handoff to the target base station.

Abstract: Provided are methods and apparatuses for triggering bandwidth part (BWP) handover, information configuring methods and apparatuses, user equipment (UE), base stations, and computer-readable storage media. The method of triggering a BWP handover includes that a UE detects that a channel on an activated BWP for the UE is busy and the UE automatically hands over to a BWP for the UE other than the activated BWP to receive data.
