Description

CROSS-REFERENCE TO RELATED APPLICATION This application is a nonprovisional and claims the benefit under 35 U.S.C. § 119(e) of U.S. Provisional Ser. No. 63/323,435 , filed Mar. 24, 2022, the contents of which are incorporated herein by reference as if fully disclosed herein. TECHNICAL FIELD This application relates generally to wireless communication systems, including systems, methods, and apparatus for monitoring a shared spectrum. BACKGROUND Wireless mobile communication technology uses various standards and protocols to transmit data between a network device (e.g., a base station) and a wireless communication device. Wireless communication system standards and protocols can include, for example, 3rd Generation Partnership Project (3GPP) long term evolution (LTE) (e.g., 4G), 3GPP new radio (NR) (e.g., 5G), 3GPP 6G, and IEEE 802.11 standard for wireless local area networks (WLAN) (commonly known to industry groups as Wi-Fi®). As contemplated by the 3GPP, different wireless communication systems standards and protocols can use various radio access networks (RANs) for communicating between a network device of the RAN (which may also sometimes be referred to generally as a RAN node, a network node, or simply a node) and a wireless communication device known as a user equipment (UE). 3GPP RANs can include, for example, global system for mobile communications (GSM), enhanced data rates for GSM evolution (EDGE) RAN (GERAN), Universal Terrestrial Radio Access Network (UTRAN), Evolved Universal Terrestrial Radio Access Network (E-UTRAN), and/or Next-Generation Radio Access Network (NG-RAN). Each RAN may use one or more radio access technologies (RATs) to perform communication between the network device and the UE. For example, the GERAN implements GSM and/or EDGE RAT, the UTRAN implements universal mobile telecommunication system (UMTS) RAT or other 3GPP RAT, the E-UTRAN implements LTE RAT (sometimes simply referred to as LTE), and NG-RAN implements NR RAT (sometimes referred to herein as 5G RAT, 5G NR RAT, or simply NR). In certain deployments, the E-UTRAN may also implement NR RAT. In certain deployments, NG-RAN may also implement LTE RAT. A network device used by a RAN may correspond to that RAN. One example of an E-UTRAN network device or base station is an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (also commonly denoted as evolved Node B, enhanced Node B, eNodeB, or eNB). One example of an NG-RAN network device or base station is a next generation Node B (also sometimes referred to as a g Node B or gNB). A RAN provides its communication services with external entities through its connection to a core network (CN). For example, E-UTRAN may utilize an Evolved Packet Core (EPC), while NG-RAN may utilize a 5G Core Network (5GC). BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWINGS To easily identify the discussion of any particular element or act, the most significant digit or digits in a reference number refer to the figure number in which that element is first introduced. FIG. 1 shows elements of an example 3GPP network and elements of an example Environmental Sensing Capability (ESC) network; FIG. 2 shows an example method of wireless communication by a 3GPP UE, which method may be used to monitor at least one shared spectrum resource for use by non-3GPP radio technology devices; FIG. 3 shows an example method of communication by a network device of a RAN (e.g., a base station), which method may be used to vacate shared spectrum used by non-3GPP radio technology devices; FIG. 4 shows an example method of communication by a network device within a core network of a 3GPP wireless communication system, which method may be used to indicate that a shared spectrum is in use by a non-3GPP radio technology device; FIG. 5 illustrates an example architecture of a wireless communication system, according to embodiments disclosed herein; and FIG. 6 illustrates a system for performing signaling between a wireless device and network devices, according to embodiments disclosed herein. DETAILED DESCRIPTION Various embodiments are described with regard to a UE. However, reference to a UE is merely provided for illustrative purposes. The example embodiments may be utilized with any electronic component that may establish a connection to a network and is configured with the hardware, software, and/or firmware to exchange information and data with a network. Therefore, the UE as described herein is used to represent any appropriate electronic device. As the number of users (both people and machines) that rely on wireless devices increases, and also as the number of uses for wireless communications increases, the need for additional spectrum over which wireless communications can be conducted may increase. Higher frequency ranges of spectrum have been allocated for 5G use (e.g., millimeter wave (mm Wave) spectrum) and 6G use (e.g., terahertz (THz) spectrum). However, due to the propagation characterist
