Scalable numerology with symbol boundary alignment for uniform and non-uniform symbol duration in wireless communication

A method of wireless communication at a scheduling entity, comprising:

• establishing communication with a first user equipment (UE) utilizing a first numerology;
• establishing communication with a second UE utilizing a second numerology, the second numerology being scaled from the first numerology such that a subcarrier spacing of the second numerology is a positive integer multiple of the first numerology;
• and
• communicating with one or more wireless devices utilizing a slot comprising the first numerology and second numerology,
• wherein the slot comprises an uplink (UL) portion, a downlink (DL) portion, and a guard period (GP) between the UL portion and DL portion such that the GP absorbs a symbol length mismatch between the first numerology and second numerology.

A scheduling entity for wireless communication, comprising:

• a communication interface configured for wireless communication utilizing a first numerology and a second numerology;
• a memory stored with executable code;
• and
• a processor operatively coupled with the communication interface and the memory,
• wherein the processor is configured by the executable code to:
• establish communication with a first user equipment (UE) utilizing the first numerology;
• establish communication with a second UE utilizing the second numerology, the second numerology being scaled from the first numerology such that a subcarrier spacing of the second numerology is a positive integer multiple of the first numerology;
• and
• communicate with the first UE and the second UE utilizing a slot comprising the first numerology and second numerology such that a symbol length of each symbol of the first numerology is equal to a sum of symbol lengths of two or more corresponding symbols of the second numerology.
