1. A method comprising:
transmitting, by a wireless device to a base station, at least one first measurement report of at least one synchronization signal of a cell;
receiving, from the base station, an indication of one or more channel state information reference signals (CSI-RSs), of the cell, based on:
the at least one first measurement report; and
a first antenna port of the one or more CSI-RSs being quasi-collocated with a second port of the at least one synchronization signal;
transmitting, based on the indication, at least one second measurement report of the one or more CSI-RSs; and
receiving, based on the at least one second measurement report, a downlink control information initiating a random access procedure of the cell based on at least one first CSI-RS from the one or more CSI-RSs.
