1. A method of wireless communication, comprising:
generating, by a user equipment (UE) of a wireless network, for a set of random access occasions of a base station of the wireless network, a random number over an interval;
for the generated random number meeting a threshold value within the interval, transmitting, by the UE and to the base station, a random access preamble within one of the random access occasions of the set of random access occasions;
for the generated random number not meeting the threshold value, attempting, by the UE, contention-based access to the wireless network within a subsequent set of random access occasions of the base station, the subsequent set of random access occasions occurring after the set of random access occasions of the base station; and
receiving, by the UE and from the base station prior to transmitting, the threshold value as an information element in at least one of a Radio Resource Control Message, a Downlink Control Information (DCI) message, a Medium Access Control-Control Element (MAC-CE) message, and a paging message.
