Dynamic time division duplexing

A method for wireless communication at a network device, comprising:

• transmitting, to a user equipment (UE), control signaling identifying a time division duplex pattern that indicates one or more transmission directions for a short transmission time interval, the short transmission time interval being shorter than a slot, and the time division duplex pattern indicating at least one flexible symbol, wherein a transmission direction of the at least one flexible symbol is reconfigurable for uplink transmissions or downlink transmissions;
• transmitting, to the UE, a downlink control information message that includes a time division duplex pattern indicator comprising an indication of a reconfiguration of a transmission direction for at least a portion of the short transmission time interval to uplink or to downlink;
• and
• communicating with the UE in the short transmission time interval based at least in part on the reconfiguration.

An apparatus for wireless communication at a user equipment (UE), comprising:

• one or more processors;
• one or more memories in electronic communication with the one or more processors;
• and
• instructions stored in the one or more memories and operable, when executed by the one or more processors, to cause the apparatus to:
• receive, from a network device, control signaling identifying a time division duplex pattern that indicates one or more transmission directions for a short transmission time interval, the short transmission time interval being shorter than a slot, and the time division duplex pattern indicating at least one flexible symbol, wherein a transmission direction of the at least one flexible symbol is reconfigurable for uplink transmissions or downlink transmissions;
• receive, from the network device, a downlink control information message that includes a time division duplex pattern indicator comprising an indication of a reconfiguration of a transmission direction for at least a portion of the short transmission time interval to uplink or to downlink;
• and
• communicate with the network device in the short transmission time interval based at least in part on the reconfiguration.
