Abstract:
In one aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided to reduce overhead at the expense of increasing latency for UEs with weak link gain, while latency for most UEs may remain the same. The apparatus may be a UE. The apparatus may transmit a RACH preamble to a base station in one or more attempts. The apparatus may receive, through a random access response message from the base station, information including the number of attempts the base station uses to decode the RACH preamble. The apparatus may adjust the transmission power for the connection request message according to the number of attempts the base station uses to decode the RACH preamble. The apparatus may transmit the connection request message using the adjusted transmission power.
