Abstract: In some embodiments, there may be provided a method that includes receiving timing advance acquisition parameters associated with multiple transmit receive points at a target distributed unit, wherein the timing advance acquisition parameters comprise, for the multiple transmit receive points, synchronization signal block indices, random access preamble indices, and physical random access channel mask indices; sending downlink control information to a user equipment, the downlink control information comprising an identifier of the target distributed unit, codepoints for the synchronization signal block indices, the random access preamble indices, and the physical random access channel mask indices; receiving timing advance estimates from the target distributed unit, wherein the timing advance estimates comprise estimates of timing advances associated with multiple transmit receive points at the target distributed unit; and sending the timing advance estimates associated with the multiple transmit receive points at the target distributed unit, to the user equipment.

Abstract: An apparatus, comprising at least one processor, and at least one memory storing instructions, the at least one memory and the instructions configured to, with the at least one processor, cause a network node to transmit a first information to at least one terminal device, wherein the first information characterizes at least one cell and/or frequency of a radio access network notification area, RNA, which is overloaded for at least one slice associated with an existing PDU session of the at least one terminal device.
