Abstract
Systems, apparatuses, methods, and computer-readable media are provided for remote interference management (RIM) in wireless networks, including RIM reference signals (RIM-RS) transmitted to assist victim radio access network (RAN) nodes to identify aggressor RAN nodes due to, for example, atmospheric ducting. The RIM-RS is also flexibly configured. Other embodiments may be described and/or claimed.
Claims20
A non-transitory computer-readable medium (CRM) having instructions that, when executed by one or more processors, causes a first radio access network (RAN) node to perform operations, the operations comprising:
- monitoring in a first time division duplex (TDD) interval and in a second TDD interval for a remote interference management-reference signal (RIM-RS) transmitted from a second RAN node, wherein the first TDD interval corresponds to a first set identifier (ID) used by the second RAN node and the second TDD interval corresponds to a second set ID used by the second RAN node;
- detecting the RIM-RS in the first TDD interval and not the second TDD interval;
- determining, based on detection of the RIM-RS in the first TDD interval and not the second TDD interval, that the second RAN node is operating according to the first set ID associated with a first transmitter of the second RAN node that transmitted the RIM-RS;
- and
- saving the first set ID in memory.
A method of operating a first radio access network (RAN) node, comprising:
- monitoring in a first time division duplex (TDD) interval and in a second TDD interval for a remote interference management-reference signal (RIM-RS) transmitted from a second RAN node, wherein the first TDD interval corresponds to a first set identifier (ID) used by the second RAN node and the second TDD interval corresponds to a second set ID used by the second RAN node;
- detecting the RIM-RS in the first TDD interval and not the second TDD interval;
- determining, based on detection of the RIM-RS in the first TDD interval and not the second TDD interval, that the second RAN node is operating according to the first set ID associated with a first transmitter of the second RAN node that transmitted the RIM-RS;
- and
- saving the first set ID in memory.
A first radio access network (RAN) node, comprising:
- radio front end circuitry configured to perform wireless communication over a wireless network;
- and
- processor circuitry, coupled to the radio front end circuitry, configured to:
- monitor in a first time division duplex (TDD) interval and in a second TDD interval for a remote interference management-reference signal (RIM-RS) transmitted from a second RAN node, wherein the first TDD interval corresponds to a first set identifier (ID) used by the second RAN node and the second TDD interval corresponds to a second set ID used by the second RAN node;
- detect the RIM-RS in the first TDD interval and not the second TDD interval;
- determine, based on the detection of the RIM-RS in the first TDD interval and not the second TDD interval, that the second RAN node is operating according to the first set ID associated with a first transmitter of the second RAN node that transmitted the RIM-RS;
- and
- save the first set ID in memory.
