Abstract

A device of a New Radio (NR) User Equipment (UE), a system, a method and a machine-readable medium. The device includes a radio frequency (RF) interface, and a processing circuitry coupled to the RF interface, the processing circuitry to: decode a message from a NR Node B (gNodeB), the message corresponding to a unicast message or to a broadcast message and being received through a Universal Mobile Telecommunications System (UMTS) interface (Uu interface), the message further including reference time information; and determine a reference time from the reference time information, the reference time to be used by higher layers of the UE.

Dependent claims

A baseband processor of a User Equipment (UE), configured to:

decode a message from a base station, the message corresponding to a unicast message or to a broadcast message and being received through a radio interface, the message further including reference time information;
and
determine a reference time from the reference time information, the reference time to be used by higher layers of the UE.

A method, comprising, with a User Equipment (UE):

decoding a message from a base station, the message corresponding to a unicast message or to a broadcast message and being received through a radio interface, the message further including reference time information;
and
determining a reference time from the reference time information, the reference time to be used by higher layers of the UE.

Dependencies are inferred from the claim text.
