The present specification provides a method for performing a radio link failure (RLF) recovery procedure in a wireless communication system. The method performed by a first user equipment (UE) includes, wherein the first UE is connected to a base station via a UE-to-UMTS (Uu) link and is connected to a second UE via a sidelink, determining a path for performing the RLF recovery procedure when a RLF is detected on the Uu link, and performing an RRC connection re-establishment procedure in order to recover the RLF through the determined path.

Mechanisms for migration of a stateless computation service in a mobile communication network. A method, performed by a control node comprises obtaining, from a core network node in the mobile communication network, information indicative of a need to migrate the stateless computation service from a source compute node in the mobile communication network. The need results from resource utilization at the source compute node is too high, and/or a demand from user equipment for the stateless computation service elsewhere in the mobile communication network. The method comprises initiating migration of the stateless computation service from the source compute node to a target compute node in the mobile communication network for hosting of the stateless computation service at the target compute node.

Systems, devices, and automated processes for user equipment (UE) to access network slices at cell sites. An example process includes receiving a registration request from the UE. The registration request includes a list of network slices for access at network cells within range of the UE. The UE is authenticated to the network to identify subscription information of the UE. A list of slice identifications (IDs) available to the UE is transmitted to the UE. A slice-specific authentication of the UE is initiated for a slice identified as available based on the subscription information. The UE is allowed to access the slice in response to the slice-specific authentication.

A UE may decode a radio-resource control (RRC) reconfiguration message comprising a conditional handover (CHO) configuration (CHO-Config) which may identify a CHO configuration for at least one target candidate cell. The CHO configuration may include two or more CHO triggering events for an entry condition. The UE may monitor measurement quantities of the target candidate cell for the entry condition to determine if any of the CHO triggering events are met, start a first count-down timer when the entry condition of a first of the CHO triggering events is met and start a second count-down timer when the entry condition of a second of the CHO triggering events is met. The UE may apply the CHO configuration to the target candidate cell when both of the two CHO triggering events remain fulfilled upon expiration of the both timers.

This disclosure provides systems, methods and apparatus for wireless communication. In one aspect, a user equipment (UE) may generate an indication of a first doppler shift associated with the wireless communication device moving with reference to a first target base station (BS), obtain, from the serving BS, a handover command for conditional handover (CHO) (with the handover command including a first trigger for handover to the first target BS), and synchronize with the first target BS during CHO after the first trigger is met, wherein the first trigger is associated with the first doppler shift. In another aspect, a serving BS generates the handover command for CHO and provides the handover command to the UE. The UE is to synchronize with the first target BS during CHO after the first trigger associated with a first doppler shift is met.

An apparatus, method and computer program product for: initiating a handover process for moving the communication session from a first access node to a second access node, interrupting the handover process in response to determining that at least one operation is to be performed by a transceiver, causing the transceiver to perform the at least one operation using the communication session with the first access node, and resuming the handover process in response to determining that the at least one operation is completed.
