Techniques for mixed numerology slot formats

A network entity, comprising:

• one or more memories storing processor-executable code;
• and
• one or more processors coupled with the one or more memories and individually or collectively operable to execute the code to cause the network entity to:
• communicate during a first slot in accordance with a first slot format, wherein, in accordance with the first slot format, each symbol of the first slot is associated with a first symbol numerology corresponding to a first subcarrier spacing;
• transmit control signaling indicative of a switch from the first slot format to a second slot format;
• and
• communicate during a second slot in accordance with the second slot format based at least in part on transmission of the control signaling, wherein, in accordance with the second slot format, a first subset of symbols of the second slot is associated with the first symbol numerology and a second subset of symbols of the second slot is associated with a second symbol numerology corresponding to a second subcarrier spacing, and wherein the second symbol numerology is different from the first symbol numerology.

A method for wireless communications at a user equipment (UE), comprising:

• communicating during a first slot in accordance with a first slot format, wherein, in accordance with the first slot format, each symbol of the first slot is associated with a first symbol numerology corresponding to a first subcarrier spacing;
• receiving control signaling indicative of a switch from the first slot format to a second slot format;
• and
• communicating during a second slot in accordance with the second slot format based at least in part on reception of the control signaling, wherein, in accordance with the second slot format, a first subset of symbols of the second slot is associated with the first symbol numerology and a second subset of symbols of the second slot is associated with a second symbol numerology corresponding to a second subcarrier spacing, and wherein the second symbol numerology is different from the first symbol numerology.
