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 bandwidth-flexible in order to enable detection of the RIM-RS by aggressor RAN nodes with different bandwidth configurations. Other embodiments may be described and/or claimed.
Claims20
A base station (BS) comprising:
- a memory;
- and
- a processor communicatively coupled to the memory, configured to:
- receive, from a second BS, a Radio Interference Management Reference Signal, (RIM-RS), wherein the RIM-RS comprises information about inter-cell interference experienced by the second BS and a base time domain sequence, wherein the base time domain sequence comprises one or more component sequences multiplexed in a frequency domain, wherein a length of a component sequence of the one or more component sequences is less than or equal to a minimum system bandwidth;
- determine the inter-cell interference based at least on the RIM-RS;
- and
- adjust a service parameter to mitigate the inter-cell interference.
A method for a base station (BS) comprising:
- receiving, from a second BS, a Radio Interference Management Reference Signal, (RIM-RS), wherein the RIM-RS comprises information about inter-cell interference experienced by the second BS and a base time domain sequence, wherein the base time domain sequence comprises one or more component sequences multiplexed in a frequency domain, wherein a length of a component sequence of the one or more component sequences is less than or equal to a minimum system bandwidth;
- determining the inter-cell interference based at least on the RIM-RS;
- and
- adjusting a service parameter to mitigate the inter-cell interference.
A non-transitory computer-readable medium storing instructions that, when executed by a processor of a base station (BS), cause the BS to perform operations, the operations comprising:
- receiving, from a second BS, a Radio Interference Management Reference Signal, (RIM-RS), wherein the RIM-RS comprises information about inter-cell interference experienced by the second BS and a base time domain sequence, wherein the base time domain sequence comprises one or more component sequences multiplexed in a frequency domain, wherein a length of a component sequence of the one or more component sequences is less than or equal to a minimum system bandwidth;
- determining the inter-cell interference based at least on the RIM-RS;
- and
- adjusting a service parameter to mitigate the inter-cell interference.
