1. A method for a user equipment (UE) configured for reduced bandwidth, low complexity, and coverage enhancement (BL/CE), the method comprising:
receiving, in system information broadcast by a network node in a radio access network (RAN), an indicator indicating that the UE is configured to provide downlink (DL) channel quality reports in a Msg3 message of a random-access (RA) procedure in a cell provided by the network node;
initiating DL channel quality measurements in response to receiving the indicator;
transmitting a RA preamble that initiates the RA procedure in the cell;
receiving a RA response grant, from the network node, indicating resources to be used for the Msg3 message; and
transmitting the Msg3 message, wherein the Msg3 message includes a DL channel quality report, determined based on the DL channel quality measurements, when the indicated resources are large enough to carry the DL channel quality report.
