Configurable common uplink burst length
Various aspects are provided for dynamic configuration of common uplink bursts. For example, the described apparatus and methods include receiving, at a user equipment (UE), an indicator of a length of a common uplink burst from a gNB, configuring the common uplink burst having the length as identified by the indicator, and transmitting, from the UE, the common uplink burst to the gNB.
