Description

Hopping monitoring configuration for radio frequency (RF) sensing and positioning Cross-reference regarding related applications This application claims the benefit of U.S. Patent Application No. 18/466,353 filed September 13, 2024, under the title of invention “HOPPING MONITORING CONFIGURATION FOR RADIO FREQUENCY (RF) SENSING AND POSITIONING,” the entirety of which is expressly incorporated by reference into this specification. Technology field Aspects of the present disclosure generally relate to wireless communication systems, and more specifically, to hopping monitoring configurations for radio frequency (RF) sensing, positioning, etc. Some features may enable and provide improved communications, including hopping monitoring configurations that provide subband baseband bandwidth hopping, antenna resource hopping, or combinations thereof. Wireless communication networks are widely deployed to provide various communication services such as voice, video, packet data, messaging, and broadcast. These wireless networks may be multiple access networks capable of supporting multiple users by sharing available network resources. Such networks may be multiple access networks that support communications for multiple users by sharing available network resources. A wireless communication network may include various components. These components may include wireless communication devices, such as network nodes (or Node B), capable of supporting communication with multiple user equipment (UEs). A UE can communicate with a network node via a downlink and an uplink. A downlink (or forward link) refers to a communication link from a network node to a UE, and an uplink (or reverse link) refers to a communication link from a UE to a network node. A network node can transmit data and control information to a UE on the downlink or receive data and control information from a UE on the uplink. On the downlink, transmissions from a network node may face interference from transmissions from neighboring network nodes or from other radio frequency (RF) transmitters. On the uplink, transmissions from a UE may face interference from uplink transmissions of other UEs communicating with neighboring network nodes or from other radio frequency (RF) transmitters. Such interference may degrade performance on both the downlink and the uplink. As the demand for mobile broadband access continues to grow, the potential for interference and network congestion increases as more UEs access long-range wireless communication networks and more short-range wireless systems are deployed in communities. Research and development continue to advance wireless technologies not only to meet the growing demand for mobile broadband access but also to improve and enhance the user experience of mobile communications. For example, the use of RF sensing is being explored in relation to facilitating various modes of monitoring, maintaining, and controlling wireless communication networks. In some examples, RF sensing may utilize dedicated frequency and time domain resources for sensing operations. In operation, RF signals may be broadcast for use in the detection, monitoring, and/or tracking (e.g., determination of location, velocity, etc.) of multiple wireless communication devices (e.g., UEs), and for monitoring and/or detection of changes in the wireless communication environment. Orthogonal Frequency Division Multiplexing (OFDM) waveforms have been considered for RF sensing due to their robustness against channel fading and multipath propagation. For example, despite drawbacks related to the peak-to-average power ratio (PAPR), OFDM signals can be attractive for RF sensing in light of the advantages associated with the absence of range-Doppler coupling—such as that occurring with linear frequency modulation waveforms—and angle estimation via multiple input, multiple output (MIMO) operations. However, OFDM waveforms for RF sensing can occupy a relatively large baseband bandwidth (e.g., 1 to 5 GHz), and wireless communication devices may need to sample the entire RF bandwidth of the OFDM waveform during RF sensing operations. For example, a bandwidth of 3 GHz may need to be sampled to provide RF sensing with a distance resolution of 5 cm. Various wireless communication devices, such as some UE implementations, may have hardware configurations that present issues related to sampling relatively large baseband bandwidth signals (e.g., analog-to-digital converters, ADCs), power utilization considerations (e.g., low-power mode operation), etc. The following summarizes some aspects of the present disclosure to provide a basic understanding of the technology discussed. This summary is not a comprehensive overview of all the features considered of the present disclosure, nor is it intended to identify the essential or important elements of all aspects of the present disclosure or to describe the scope of any or all aspects of the present disclosure.
