Reduction of ISO bandwidth on a central wireless device

A method for wireless communications at a central wireless device, comprising:

• monitoring, in a first subevent of a plurality of isochronous subevents of an isochronous interval, for a first data packet from a first peripheral wireless device of a plurality of peripheral wireless devices in a connected isochronous group, the first data packet associated with a first sequence number;
• monitoring, in a second subevent of the plurality of isochronous subevents of the isochronous interval, for a second data packet from a second peripheral wireless device of the plurality of peripheral wireless devices in the connected isochronous group, the second data packet associated with a second sequence number;
• transmitting, in a third subevent of the plurality of isochronous subevents of the isochronous interval and to the plurality of peripheral wireless devices in the connected isochronous group, a group feedback message based at least in part on the monitoring, wherein the group feedback message includes acknowledgment information corresponding to the first data packet and the second data packet;
• and
• wherein the first peripheral wireless device is associated with a first set of one or more subevents of the isochronous interval and the second peripheral wireless device is associated with a second set of one or more subevents of the isochronous interval, the third subevent is associated with one of the first set of one or more subevents or the second set of one or more subevents and transmitting an indication of which of the first set of one or more subevents or the second set of one or more subevents to monitor for the group feedback message.

A first peripheral wireless device of a plurality of peripheral wireless devices in a connected isochronous group, comprising:

• a processing system that includes processor circuitry and memory circuitry that stores code, the processing system configured to cause the first peripheral wireless device of a plurality of peripheral wireless devices in a connected isochronous group to:
• transmit, in a first subevent of a plurality of isochronous subevents of an isochronous interval, a first data packet associated with a first sequence number;
• receive, in a second subevent of the plurality of isochronous subevents of the isochronous interval, a group feedback message based at least in part on transmitting the first data packet, wherein the group feedback message includes acknowledgment information corresponding to the first data packet and a second data packet from a second peripheral wireless device of the plurality of peripheral wireless devices in the connected isochronous group;
• and
• wherein the acknowledgment information includes a first next expected sequence number for the first peripheral wireless device and a second next expected sequence number for the second peripheral wireless device.
