1. A method of wireless communication performed by a user equipment (UE), comprising:
determining that a signal-to-noise ratio (SNR) of one or more communications from a serving cell satisfies an SNR threshold after establishing a New Radio (NR) radio resource control (RRC) connection with the serving cell;
transmitting a measurement message to the serving cell based at least in part on the determining that the SNR of the one or more communications from the serving cell satisfies the SNR threshold;
receiving, from the serving cell, a list of one or more neighbor cells based at least in part on the transmitting the measurement message; and
establishing an RRC connection to a neighbor cell on the list based at least in part on determining that a radio link failure occurred.
