Distributed scheduling to control interference for data transactions using grant-less transmissions

An apparatus for wireless communications by a wireless node, comprising:

• a receiver configured to receive, from a base station, a plurality of modulation and coding schemes (MCS) and, for each MCS, a maximum duration constraint or a maximum payload size constraint for grant-less transmission using the MCS;
• at least one processor configured to:
• determine a data rate and duration for a grant-less transmission based on a selected MCS from the plurality of MCS and the maximum duration constraint or the maximum payload size constraint associated with the selected MCS, and
• select access resources to use for the grant-less transmission from a common pool of resources configured to be shared by a plurality of wireless nodes for grant-less transmissions;
• and
• a transmitter configured to:
• transmit a first portion of the grant-less transmission using the selected access resources, at the determined data rate and for the determined duration;
• and
• when the maximum duration constraint or the maximum payload size constraint is reached, request a grant for transmitting a second portion of the grant-less transmission.
