Detection of deployed time-domain duplexed repeaters

An apparatus for detecting a repeater on a propagation path at a transmitting device of a wireless communication network, comprising:

• memory storing instructions;
• and
• a processor in communication with the memory and configured to execute the instructions to:
• receive, from a controlling entity, a repeater detection configuration indicating a detection threshold and at least one transmit power level;
• transmit, to a receiving device via the propagation path and according to the repeater detection configuration, a first signal at a first power level;
• receive, in response to transmitting the first signal, first measurement results of the first signal;
• transmit, to the receiving device via the propagation path and according to the repeater detection configuration, a second signal at a second power level, the second power level being different than the first power level;
• receive, in response to transmitting the second signal, second measurement results of the second signal;
• detect an active repeater on the propagation path in response to a difference between the first measurement results and the second measurement results satisfying the detection threshold;
• determine, in response to detecting the active repeater, configuration information of the active repeater;
• perform, according to the configuration information of the active repeater and in response to detecting the active repeater, at least one of interference management, beam management, positioning, or mobility management;
• and
• communicate at least one transmission via the active repeater and according to the configuration information of the active repeater.

A method of detecting a repeater on a propagation path at a receiving device of a wireless communication network, comprising:

• receiving, from a controlling entity, a repeater detection configuration indicating at least a detection threshold;
• receiving, from a transmitting device via the propagation path, a first signal having been transmitted at a first power level indicated by the repeater detection configuration;
• performing first measurements of the first signal resulting in first measurement results;
• receiving, from the transmitting device via the propagation path, a second signal having been transmitted at a second power level indicated by the repeater detection configuration;
• performing second measurements of the second signal resulting in second measurement results;
• detecting an active repeater on the propagation path in response to a difference between the first measurement results and the second measurement results satisfying the detection threshold;
• determining, in response to detecting the active repeater, configuration information of the active repeater;
• performing, according to the configuration information of the active repeater and in response to detecting the active repeater, at least one of interference management, beam management, positioning, or mobility management;
• and
• communicating at least one transmission via the active repeater and according to the configuration information of the active repeater.
