Assignee: ZTE CORPORATION
Field: Digital communication (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 0:
1. A method of wireless communication, comprising:
repeatedly transmitting, from a mobile device to a communication node, a first message using increasing power levels for initiating a two-step random-access procedure until a termination condition is met, wherein the first message includes a payload part and a preamble sequence,
wherein transmitting the first message includes:
incrementing a first counter tracking a number of repeated transmissions of the payload part;
incrementing a second counter tracking a power ramping level corresponding to the repeated transmissions of the payload part;
and wherein the termination condition includes: the first counter tracking the number of repeated transmission of the payload part reaches a first threshold;
reselecting, by the mobile device, the preamble sequence upon determining that the first counter reaches the first threshold, wherein a number of times the preamble sequence is reselected is less than a second threshold;
transmitting, from the mobile device, a second message to the communication node, wherein the second message includes the reselected preamble sequence and the payload part;
incrementing a third counter tracking the number of times the preamble sequence is reselected; and
incrementing a fourth counter tracking a preamble power ramping level corresponding to the reselected preamble sequence.
