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 radio front end circuitry;
- and
- baseband circuitry coupled to the radio front end circuitry, the baseband circuitry configured to:
- generate a Radio Interference Management Reference Signal (RIM-RS), wherein the RIM-RS comprises information about experienced inter-cell interference and a base time domain sequence, including
- multiplex one or more component sequences 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;
- and
- transform the multiplexed component sequences into the base time domain sequence;
- and
- transmit, via the front end circuitry, the RIM-RS to an other BS.
A method for a base station (BS) comprising:
- generating a Radio Interference Management Reference Signal, (RIM-RS), wherein the RIM-RS comprises information about experienced inter-cell interference and a base time domain sequence, including
- multiplexing one or more component sequences 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;
- and
- transforming the multiplexed component sequences into the base time domain sequence;
- and
- transmitting the RIM-RS to an other BS.
A non-transitory computer readable medium (CRM) storing instructions that, when executed by a processor of a base station (BS), cause the BS to perform operations, the operations comprising:
- generating a Radio Interference Management Reference Signal (RIM-RS), wherein the RIM-RS comprises information about experienced inter-cell interference and a base time domain sequence, including
- multiplexing one or more component sequences 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;
- and
- transforming the multiplexed component sequences into the base time domain sequence;
- and
- transmitting the RIM-RS to an other BS.
