Devices, systems and methods for high-utilization low-latency multi-channel time-division multiplexing access (TDMA) are described. One example method for wireless communication includes performing, in a first time interval of a time-division multiple access (TDMA) slot, a transmission of a first data unit over a first logical channel of the plurality of logical channels, refraining from transmitting, subsequent to a completion of the transmission of the first data unit, for a second time interval immediately after the first time interval, and performing (N-1) transmissions in (N-1) time intervals for each data unit of (N-1) subsequent data units in the TDMA slot, such that a transmission of an nth data unit of the (N-1) subsequent data units is performed over an nth logical channel of the plurality of logical channels.
