low latency group commits

摘要

Certain aspects of the present disclosure provide techniques that can be used for low latency communications. for example, aspects allow a single group commit to be used to commit a plurality of low latency transmissions. an exemplary method generally includes receiving from a base station a plurality of downlink channel transmissions; wherein each of the downlink channel transmissions is sent using a first transmission time slot (tti) that is shortened relative to a legacy tti and provide in a single uplink channel transmission sent using a second tti which is greater than the first tti, a group acknowledgment indicating whether or not the downlink channel transmissions were successfully received by a eu.
