Mitigating access congestion on a wireless network

A method for wireless communication at a user equipment (UE), comprising:

• transmitting a first random access preamble to a network device, the first random access preamble comprising a preamble index associated with the UE;
• receiving a random access response from the network device, the random access response comprising an indication of a dynamic random access configuration and a plurality of dynamic uplink grants;
• applying either the dynamic random access configuration or a randomly selected uplink grant of the plurality of dynamic uplink grants to the UE, wherein the applying is based at least in part on whether the random access response includes the preamble index associated with the UE;
• and
• transmitting a second random access preamble to the network device in accordance with the applied dynamic random access configuration or the applied randomly selected uplink grant.

A user equipment (UE) for wireless communication, comprising:

• means for transmitting a first random access preamble to a network device, the first random access preamble comprising a preamble index associated with the UE;
• means for receiving a random access response from the network device, the random access response comprising an indication of a dynamic random access configuration and a plurality of dynamic uplink grants;
• means for applying either the dynamic random access configuration or a randomly selected uplink grant of the plurality of dynamic uplink grants to the UE, wherein the applying is based at least in part on whether the random access response includes the preamble index associated with the UE;
• and
• means for transmitting a second random access preamble to the network device in accordance with the applied dynamic random access configuration or the applied randomly selected uplink grant.

A non-transitory computer-readable medium storing code for wireless communication, the code comprising instructions executable by at least one processor to:

• transmit a first random access preamble to a network device, the first random access preamble comprising a preamble index associated with a user equipment (UE);
• receive a random access response from the network device, the random access response comprising an indication of a dynamic random access configuration and a plurality of dynamic uplink grants;
• apply either the dynamic random access configuration or a randomly selected uplink grant of the plurality of dynamic uplink grants to the UE, wherein the applying is based at least in part on whether the random access response includes the preamble index associated with the UE;
• and
• transmit a second random access preamble to the network device in accordance with the applied dynamic random access configuration or the applied randomly selected uplink grant.
