Random access collision reduction based on multiple uplink grants

A method for wireless communication at a network access device, comprising:

• receiving a random access preamble;
• identifying a number of uplink grants to associate with the random access preamble, the identified number of uplink grants including at least one uplink grant associated with at least one transmission resource, the identified number of uplink grants based at least in part on a time-variable parameter;
• and
• transmitting a random access response message including the identified number of uplink grants.

An apparatus for wireless communication at a user equipment (UE), comprising:

• a processor;
• memory in electronic communication with the processor;
• and
• the processor and memory configured to:
• transmit a random access preamble;
• receive a random access response message that includes a plurality of uplink grants associated with the random access preamble, wherein each uplink grant in the plurality of uplink grants is associated with a different transmission resource;
• select an uplink grant from the plurality of uplink grants;
• and
• transmit using the selected uplink grant.
