Abstract: A method and apparatus for timing advance (TA) synchronization for uplink (UL) data transmissions are provided. A base station transmits a TA instruction to a UE. The TA instruction indicates one of at least two TA options. The first TA option indicates direct initial grant-free (GF) uplink (UL) data transmissions. The second TA option indicates indirect initial GF UL data transmissions with the UE initiating TA reference signaling for updating a TA parameter of the UE. The UE performs an initial GF UL data transmission to the base station based on the TA instruction.

Abstract: Solution for security negotiation during handover of a user equipment (UE) between different radio access technologies is provided. In the solution, the UE receives non-access stratum (NAS) security information and access stratum (AS) security information which are selected by the target system and then performs security negotiation with the target system according to the received NAS security information and AS security information. As such, the UE may obtain the key parameter information of the NAS and AS selected by a long term evolution (LTE) system and perform security negotiation with the LTE system when the UE hands over from a different system, such as a universal terrestrial radio access network (UTRAN), to the LTE system.
