Abstract
Methods and apparatus for determining a PRS configuration in a dynamic TDD configuration adaptation are described. One example method generally includes determining a first PRS configuration for receiving PRS when communicating according to a first subframe configuration that defines one or more uplink subframes and one or more downlink subframes, receiving an indication of a switch from the first subframe configuration to a second subframe configuration, and determining a second PRS configuration for receiving PRS when communicating according to the second subframe configuration.

A method for wireless communications by a user equipment (UE), comprising:
- determining a first positioning reference signal (PRS) configuration for receiving PRS when communicating according to a first subframe configuration that defines one or more uplink subframes and one or more downlink subframes;
- receiving an indication of a switch from the first subframe configuration to a second subframe configuration;
- and
- determining a second PRS configuration for receiving PRS when communicating according to the second subframe configuration.
An apparatus for wireless communications by a user equipment (UE), comprising:
- means for determining a first positioning reference signal (PRS) configuration for receiving PRS when communicating according to a first subframe configuration that defines one or more uplink subframes and one or more downlink subframes;
