WO-2026096123-A1 - HANDOVER WITH LOCATION STATE INFORMATION

Abstract

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a first network node may transmit, to a second network node, a handover request message indicating a handover request for a user equipment (UE), wherein the second network node is configured to support a non-terrestrial network (NTN) cell, and wherein the handover request message includes first information indicative of a location resolution operational state of the UE. The first network node may receive, from the second network node, a handover acknowledgment message that includes second information indicating whether the handover request is accepted, wherein the second information is associated with the location resolution operational state. Numerous other aspects are described.

Description

HANDOVER WITH LOCATION STATE INFORMATION CROSS-REFERENCE TO RELATED APPLICATION [0001] This Patent Application claims priority to U.S. Patent Application No. 18/931 ,975, filed on October 30, 2024, entitled “HANDOVER WITH LOCATION STATE INFORMATION,” and assigned to the assignee hereof. The disclosure of the prior Application is considered part of and is incorporated by reference into this Patent Application. FIELD OF THE DISCLOSURE [0002] Aspects of the present disclosure generally relate to wireless communication and specifically relate to techniques, apparatuses, and methods associated with a handover with location state information. BACKGROUND [0003] Wireless communication systems are widely deployed to provide various services, which may involve carrying or supporting voice, text, other messaging, video, data, and/or other traffic. Typical wireless communication systems may employ multiple-access radio access technologies (RATs) capable of supporting communication among multiple wireless communication devices including user devices or other devices by sharing the available system resources (for example, time domain resources, frequency domain resources, spatial domain resources, and/or device transmit power, among other examples). Such multiple-access RATs are supported by technological advancements that have been adopted in various telecommunication standards, which define common protocols that enable different wireless communication devices to communicate on a local, municipal, national, regional, or global level. [0004] An example telecommunication standard is New Radio (NR). NR, which may also be referred to as 5G, is part of a continuous mobile broadband evolution promulgated by the Third Generation Partnership Project (3GPP). NR (and other RATs beyond NR) may be designed to better support enhanced mobile broadband (eMBB) access, Internet of things (loT) networks or reduced capability device deployments, and ultra-reliable low latency communication (URLLC) applications. To support these verticals, NR systems may be designed to implement a modularized functional infrastructure, a disaggregated and service-based network architecture, network function virtualization, network slicing, multi-access edge computing, millimeter wave (mmWave) technologies including massive multiple -input multiple-output (MIMO), licensed and unlicensed spectrum access, non-terrestrial network (NTN) deployments, sidelink and other device-to-device direct communication technologies (for example, cellular vehicle-to- everything (CV2X) communication), multiple-subscriber implementations, high-precision 0097-5807PCT 1 positioning, and/or radio frequency (RF) sensing, among other examples. As the demand for connectivity continues to increase, further improvements in NR may be implemented, and other RATs, such as 6G and beyond, may be introduced to enable new applications and facilitate new use cases. SUMMARY [0005] Some aspects described herein relate to a first network node for wireless communication. The first network node may include one or more memories and one or more processors coupled to the one or more memories.

The one or more processors may be configured to cause the first network node to receive, from the second network node, a handover acknowledgment message that includes second information indicating whether the handover request is accepted, wherein the second information is associated with the location resolution operational state. [0006] Some aspects described herein relate to a first network node for wireless communication.
