Description

FIELD OF THE DISCLOSURE Aspects of the present disclosure generally relate to wireless communication and to techniques and apparatuses for radio frequency map aggregation. BACKGROUND Wireless communication systems are widely deployed to provide various telecommunication services such as telephony, video, data, messaging, and broadcasts. Typical wireless communication systems may employ multiple-access technologies capable of supporting communication with multiple users by sharing available system resources (e.g., bandwidth, transmit power, or the like). Examples of such multiple-access technologies include code division multiple access (CDMA) systems, time division multiple access (TDMA) systems, frequency division multiple access (FDMA) systems, orthogonal frequency division multiple access (OFDMA) systems, single-carrier frequency division multiple access (SC-FDMA) systems, time division synchronous code division multiple access (TD-SCDMA) systems, and Long Term Evolution (LTE). LTE/LTE-Advanced is a set of enhancements to the Universal Mobile Telecommunications System (UMTS) mobile standard promulgated by the Third Generation Partnership Project (3GPP). A wireless network may include one or more network nodes that support communication for wireless communication devices, such as a user equipment (UE) or multiple UEs. A UE may communicate with a network node via downlink communications and uplink communications. “Downlink” (or “DL”) refers to a communication link from the network node to the UE, and “uplink” (or “UL”) refers to a communication link from the UE to the network node. Some wireless networks may support device-to-device communication, such as via a local link (e.g., a sidelink (SL), a wireless local area network (WLAN) link, and/or a wireless personal area network (WPAN) link, among other examples). The above multiple access technologies have been adopted in various telecommunication standards to provide a common protocol that enables different UEs to communicate on a municipal, national, regional, and/or global level. New Radio (NR), which may be referred to as 5G, is a set of enhancements to the LTE mobile standard promulgated by the 3GPP. NR is designed to better support mobile broadband internet access by improving spectral efficiency, lowering costs, improving services, making use of new spectrum, and better integrating with other open standards using orthogonal frequency division multiplexing (OFDM) with a cyclic prefix (CP) (CP-OFDM) on the downlink, using CP-OFDM and/or single-carrier frequency division multiplexing (SC-FDM) (also known as discrete Fourier transform spread OFDM (DFT-s-OFDM)) on the uplink, as well as supporting beamforming, multiple-input multiple-output (MIMO) antenna technology, and carrier aggregation. As the demand for mobile broadband access continues to increase, further improvements in LTE, NR, and other radio access technologies remain useful. SUMMARY In some aspects, a method of wireless communication performed by a user equipment (UE) includes transmitting position information regarding a position of the UE and camera information captured by the UE; receiving a radio frequency (RF) map, wherein the RF map is associated with the position information; and transmitting information indicating an update to the RF map. In some aspects, a method of wireless communication performed by a network node includes receiving position information regarding a position of a UE and camera information captured by the UE; and transmitting a RF map, wherein the RF map is associated with the position information. In some aspects, an apparatus for wireless communication at a UE includes one or more memories; and one or more processors, coupled to the one or more memories, individually or collectively configured to cause the UE to: transmit position information regarding a position of the UE and camera information captured by the UE; receive a RF map, wherein the RF map is associated with the position information; and transmit information indicating an update to the RF map. In some aspects, an apparatus for wireless communication at a network node includes one or more memories; and one or more processors, coupled to the one or more memories, individually or collectively configured to cause the network node to: receive position information regarding a position of a UE and camera information captured by the UE; and transmit a RF map, wherein the RF map is associated with the position information. In some aspects, a non-transitory computer-readable medium storing a set of instructions for wireless communication includes one or more instructions that, when executed by one or more processors of a UE, cause the UE to: transmit position information regarding a position of the UE and camera information captured by the UE; receive a RF map, wherein the RF map is associated with the position information; and transmit information indicating an update to the RF map.
