a spatial location of the UE, or
an orientation of the UE.
12 . An apparatus for wireless communication at a network node, comprising:
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 user equipment (UE) and camera information captured by the UE;
transmit a radio frequency (RF) map, wherein the RF map is associated with the position information; and
receive information indicating an update to the RF map.
13 . The apparatus of claim 12 , wherein the one or more processors are individually or collectively configured to cause the network node to update the RF map in accordance with the information indicating the update to the RF map; and
transmit the updated RF map to a second UE.
14 . The apparatus of claim 12 , wherein the RF map, as transmitted, uses a coordinate system of the position information.
15 . The apparatus of claim 14 , wherein the one or more processors are individually or collectively configured to cause the network node to apply a transformation to a coordinate system of a baseline RF map to generate the RF map as transmitted to the UE.
16 . The apparatus of claim 15 , wherein the transformation is based at least in part on at least one of the position information or the camera information.
17 . The apparatus of claim 12 , wherein the one or more processors are individually or collectively configured to cause the network node to transmit signaling that enables at least one of reception of the RF map, transmission of the position information or the camera information, or transmission of information indicating an update to the RF map.
18 . The apparatus of claim 12 , wherein the one or more processors are configured to cause the network node to receive uplink control information indicating a use case for the RF map.
