9. The method of claim 1, wherein the signal characteristics of the unicast signal are based, at least in part, on a channel state information reference signal.

10. The method of claim 1, wherein signal characteristics of the broadcast signal are based at least in part on at least of a channel state information reference signal, a synchronization signal, a demodulation reference signal, or a combination thereof.

11. The method of claim 1, wherein the request is to provide a single update to the MIB or the MSIB using the unicast signal.

12. The method of claim 1, wherein the UE is in a radio resource control connected mode prior to or when determining that the signal characteristics of the unicast signal are better than the signal characteristics of the broadcast signal.

13, a wireless communication method performed by a base station, comprising:

determining that a signal characteristic of a unicast signal associated with a User Equipment (UE) is better than a signal characteristic of a broadcast signal broadcast by the base station , and

transmitting, by the base station and based at least in part on the determining, an update to a Master Information Block (MIB) or a Minimum System Information Block (MSIB) to the UE using the unicast signal.

14. The method of claim 13, wherein signal characteristics of the unicast signal and signal characteristics of the broadcast signal are based, at least in part, on measurement information for the unicast signal and the broadcast signal.

15, a User Equipment (UE) for wireless communication, comprising:

a memory; and

or more processors operatively coupled to the memory, the memory and the or more processors configured to:

determining that the signal characteristics of the unicast signal are better than the signal characteristics of the broadcast signal, and

transmitting, based at least in part on the determining, a request to provide an update to a Master Information Block (MIB) or a Minimum System Information Block (MSIB) to the UE using the unicast signal.

16. The UE of claim 15, wherein the memory and the or more processors are further to :

receiving a grant of the update to the MIB or the MSIB based at least in part on scheduling of the update to the MIB or the MSIB by a scheduling entity; and
