US 2024/0196469 A1 · New Radio Wakeup Radio

Abstract

Apparatuses, systems, and methods for a wakeup radio in a wireless communication system, e.g., in 5G NR systems and beyond. An RRC state is introduced to support a wakeup radio/, including defining transition mechanisms to/from existing RRC states. Further, signaling is introduced to activate a wakeup radio/activate an RRC low power state. Additionally, a bandwidth part framework for a wakeup signal is defined in which a base station may configure one or more time/frequency resources or a wakeup signal for a wakeup radio. In addition, various mechanisms are introduced to switch a wakeup radio on as well as to switch a wakeup radio off. Also, mechanisms are introduced for multiplexing multiple wakeup signals in a time/frequency resource, configuring a wakeup signal bandwidth, and configuring which beam a wakeup signal may be received on.

Dependent claims

A user equipment device (UE), comprising:

at least one antenna;
at least one primary communication radio, wherein the at least one primary communication radio is configured to perform communication using at least one radio access technology (RAT);
at least one wakeup radio;
and
one or more processors coupled to the at least one primary communication radio and the at least one wakeup radio, wherein the one or more processors and the at least one primary communication radio and at least one wakeup radio are configured to perform communications;
wherein the one or more processors are configured to cause the UE to:
operate in a first radio resource control (RRC) state, wherein, in the first RRC state, a primary communication radio of the UE is powered on and a wakeup radio of the UE is powered off;
receive, while operating in the first RRC state, a signal indicating a transition to a second RRC state, wherein, in the second RRC state, the primary communication radio of the UE is powered off and the wakeup radio of the UE is powered on;
and
transition to a second RRC state based on receipt of the signal.
