Multi-subcarrier system with multiple numerologies

A radio access node, comprising:

• processing circuitry in communication with memory having executable instructions thereon;
• and
• at least one transmitter and/or receiver in communication with the processing circuitry and memory and collectively configured to:
• allocate multi-subcarrier system resources using a first numerology and a second numerology within a radio-frequency carrier supported within a channel bandwidth of the radio access node, wherein:
• the first numerology has resource blocks (RBs) with a first bandwidth and a first subcarrier spacing (Δf1), the RBs of the first numerology starting at a frequency relative to a frequency reference (Fref) according to m*Δf1+Fref, m being an integer,
• the second numerology has RBs with a second bandwidth and a second subcarrier spacing (Δf2), the RBs of the second numerology starting at a frequency relative to Fref according to n*Δf2+Fref, n being an integer, and
• transmit information within the single carrier according to the first and second numerologies.

A user equipment, comprising:

• processing circuitry in communication with memory having executable instructions thereon;
• and
• at least one transmitter and/or receiver in communication with the processing circuitry and memory and collectively configured to:
• indexing resources of multi-subcarrier system using at least one of a first numerology and a second numerology available within a single RF carrier, wherein:
• the first numerology has resource blocks (RBs) with a first bandwidth and a first subcarrier spacing (Δf1), the RBs of the first numerology starting at a frequency relative to a frequency reference (Fref) according to m*Δf1+Fref, m being an integer,
• the second numerology has RBs with a second bandwidth and a second subcarrier spacing (Δf2), the RBs of the second numerology starting at a frequency relative to Fref according to n*Δf2+Fref, n being an integer, and
• transmitting and/or receiving information within the single carrier according to the at least one of the first and second numerologies.
