Organization of inter-relay discovery reference signals

A method for wireless communication at a parent node of a wireless communications system, comprising:

• receiving, from a relay node of the wireless communications system, a report indicating a duplexing capability of the relay node;
• determining discovery reference signal (DRS) transmission resources and DRS measurement resources for the relay node based at least in part on the indicated duplexing capability of the relay node;
• and
• transmitting, to the relay node, a configuration that identifies the determined DRS transmission resources and the determined DRS measurement resources.

An apparatus for wireless communication at a relay node of a wireless communications system, comprising:

• a processor;
• memory coupled with the processor;
• and
• instructions stored in the memory and operable, when executed by the processor, to cause the apparatus to:
• transmit, to a parent node of the wireless communications system, a report indicating a duplexing capability of the relay node;
• receive, from the parent node, a configuration that identifies discovery reference signal (DRS) transmission resources and DRS measurement resources for the relay node in accordance with the indicated duplexing capability of the relay node;
• transmit a DRS using the identified DRS transmission resources;
• and
• monitor for DRSs from other nodes of the wireless communications system using the identified DRS measurement resources.
