Description

FIELD OF THE DISCLOSURE Aspects of the present disclosure generally relate to wireless communication and specifically relate to techniques, apparatuses, and methods associated with data offload from a relay device. BACKGROUND 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. 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 (IoT) 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 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. In some wireless communication networks, data connectivity for one or more wireless devices may be facilitated through an intermediary device that is enabled to communicate over multiple radio access technologies (RATs). For example, a relay device, which may be capable of accessing a wireless wide area network (WWAN), may extend network connectivity to one or more client devices that lack direct access to the WWAN (such as a client device without a subscription or other authorization to directly access the WWAN). The relay device may extend such network connectivity through wireless local area network (WLAN) technologies, where the relay device acts as an intermediary, bridging the gap between a WWAN RAT (for example, 4G Long Term Evolution (LTE) or 5G New Radio (NR), among other examples) and a WLAN RAT (for example, an IEEE 802.11 wireless communication protocol, commonly known as “Wi-Fi”). For example, the relay device may communicate directly with a network node via a WWAN link, and may communicate directly with a client device via a WLAN link. Therefore, the relay device may operate in accordance with WWAN and WLAN capabilities to create a multiple RAT (multi-RAT) access bridge, where the client device communicates with the relay device to transmit and/or receive data via the WLAN link, and the relay device communicates with the network node via the WWAN link to relay the transmitted and/or received data on behalf of the client device. SUMMARY Some aspects described herein relate to a client wireless communication device for wireless communication. The client wireless communication device may include a processing system that includes one or more processors and one or more memories coupled with the one or more processors. The processing system may be configured to cause the client wireless communication device to transmit, to a relay wireless communication device and via a first radio access technology (RAT), information indicating one or more capabilities associated with a second RAT. The processing system may be configured to cause the client wireless communication device to receive, from the relay wireless communication device and via the first RAT, configuration information for a cell group associated with a network node, the configuration information being associated with the one or more capabilities associated with the second RAT. The processing system may be configured to cause the client wireless communication device to transmit, to the network node and via the second RAT
