Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive control signaling identifying a configuration of a set of uplink slots for the UE to transmit uplink reference signals to a satellite. The UE may transmit, to the satellite, a set of uplink reference signals on the set of uplink slots according to the configuration. The set of uplink reference signals may include sounding reference signals (SRSs), positioning references signals (PRSs), or both. In some implementations, the UE may transmit the set of uplink reference signals in accordance with one or more timing advance values, where the timing advance values are indicated to the satellite by the UE, pre-configured by the satellite, or both. The UE may then, from a network node, an indication of a position of the UE based on the set of uplink reference signals.

Presented herein are techniques for assigning Ultra-Wideband (UWB) anchors for client ranging. A location server can estimate a coarse location of a mobile device using a localization technique other than a UWB localization technique. The localization technique can involve multiple wireless access points or other radio devices. The location server can define an area around the coarse location to identify a set of candidate anchors for UWB ranging. The set of candidate anchors can be disposed within the area and include at least a subset of the radio devices. The location server can modify the set of candidate anchors to create a modified set of candidate anchors that includes only UWB-enabled devices. The location server can select a primary anchor from the modified set of candidate anchors and send a command to cause a UWB ranging procedure to be initiated between the primary anchor and the mobile device.
