Processing time for wideband precoding in subband full-duplex

A network entity, comprising:

• at least one processor;
• and
• memory coupled with the at least one processor, the memory storing instructions executable by the at least one processor to cause the network entity to:
• transmit a control message indicating a wideband precoding configuration for wideband precoding of two or more downlink subbands for subband full-duplex communication;
• transmit at least one grant scheduling a downlink shared channel via the two or more downlink subbands within a subband full-duplex transmission time interval;
• transmit, in accordance with the at least one grant, downlink data via the two or more downlink subbands of the downlink shared channel;
• and
• receive, via a feedback transmission time interval, a feedback message for the downlink data, wherein a first time period between the subband full-duplex transmission time interval and the feedback transmission time interval is based at least in part on the wideband precoding configuration and the at least one grant.

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

• receiving a control message indicating a wideband precoding configuration for wideband precoding of two or more downlink subbands for subband full-duplex communication;
• receiving at least one grant scheduling a downlink shared channel via the two or more downlink subbands within a subband full-duplex transmission time interval;
• receiving, in accordance with the at least one grant, downlink data via the two or more downlink subbands of the downlink shared channel;
• and
• transmitting, via a feedback transmission time interval, a feedback message for the downlink data, wherein a first time period between the subband full-duplex transmission time interval and the feedback transmission time interval is based at least in part on the wideband precoding configuration and the at least one grant.
