Various solutions for power saving for New Radio (NR) carrier aggregation in mobile communications are described. An apparatus receives, from a wireless network, a trigger signal. The apparatus switches between a first bandwidth part (BWP) and a second BWP of at least two BWPs for a secondary cell (SCell) in response to receiving the trigger signal. No physical downlink control channel (PDCCH) monitoring is configured for the first BWP while PDCCH monitoring is configured for the second BWP.

A device may send a first message to a user device requesting information identifying a radio access technology (RAT) or a band supported by and enabled on the user device. The device may receive an indication of the RAT or band supported by and enabled on the user device and send, to the user device, a second message instructing the user device to modify the RAT or band enabled on the user device. The second message may include an indication of updated RAT or band information. The device may receive from the user device, a confirmation that the RAT or band enabled on the user device has been modified.

The invention refers to a method for performing a handover of a user equipment, UE (10), from one or a plurality of source beams of a source access node, AN (14) to one or a plurality of target beams of a target access node, AN (16), wherein the target AN performs the steps of receiving from the source AN (14) a positioning information indicative of a first position estimate of an actual position of the UE (10), determining or initiating determining a resulting position estimate, wherein the resulting position estimate is derived from the first position estimate, and activating the one or the plurality of target beams in dependency of the resulting position estimate. The invention further refers to a method wherein the target AN (16) performs the steps of receiving from the source AN the positioning information indicative of a first position estimate, determining or initiating determining a second position estimate associated to the an actual position of the UE (10), determining or initiating determining a delta position between the first position estimate and the second position estimate, and storing or initiating storing the delta position. The invention further refers to a method wherein the source AN (14) performs the steps of determining or initiating determining a first position estimate of an actual position of the UE (10), and sending to the target AN (16) an information indicative of the first position estimate of an actual position of the UE (10). The invention further refers to corresponding access nodes (14, 16) and a software program.

A method for requesting a target system information block (SIB) associated with a target service is provided. The method initiates a dedicated SIB request procedure to send, to a serving cell, a request for the target SIB. The method initiates the dedicated SIB request procedure while the UE has stored at least one SIB segment of a plurality of SIB segments associated with the target SIB, and before the target SIB is successfully assembled based on the plurality of SIB segments. The method transmits, to the serving cell, the request for the target SIB to the serving cell and upon the transmission of the request starts a timer, where a second dedicated SIB request procedure is not allowed to be initiated while the timer is running.

Aspects of the present disclosure provide a method for wireless communications by a user equipment (UE). The method generally includes receiving signaling configuring multiple candidate target physical cell identifiers (PCIs) of at least one candidate target cell that supports physical (PHY) layer or medium access control (MAC) layer mobility signaling, participating in a handover procedure to a target cell associated with a selected one or more of the candidate target PCIs based on PHY layer or MAC layer mobility signaling, receiving, from the target cell, a response message indicating success of the handover procedure, and terminating activity with one or more source PCIs after receiving the response message.

An information processing apparatus includes a communication unit and a switching unit. The communication unit is configured to conduct a wireless communication using plural transmission methods, one of which has plural channels. When a channel or transmission method having a higher communication quality than that of a communication that is being conducted has become able to communicate, the switching unit switches to the channel or the transmission method having the higher communication quality.

A device can receive, from first user equipment, information that relates to a first application, where the information includes a plurality of S-NSSAI. The device can determine whether the plurality of S-NSSAI are configured as a group of associated S-NSSAI. The device can determine that a preference is to be given to one of: communication sessions associated with the first application relative to a communication session associated with a second application, that does not utilize multiple network slices, of the first user equipment or second user equipment; traffic flows associated with the first application relative to a traffic flow associated with the second application; or a plurality of network slices associated with the first application relative to a network slice associated with the second application. The device can perform one or more actions based on determining the preference to thereby facilitate a particular functionality of the first application.
