1. A method, comprising:
broadcasting, by a network node in a wireless network, an initial bandwidth part to a user equipment in system information,
selecting, the network node, at least one bandwidth part based on an incoming data type, a required quality for a connection to be established, or both;
sending, by the network node toward the user equipment, an indication of the selected at least one bandwidth part to be used by the user equipment during a connection establishment procedure to connect the user equipment to the wireless network, wherein the selected at least one bandwidth part is wider than the initial bandwidth part, and wherein the selected at least one bandwidth part is sent via paging or system information after the user equipment transitions to idle/inactive state, the wider bandwidth part is utilized for an msg3 message of random access procedure; and
in response to receiving, by the network node and from the user equipment, the msg3 message for a connection establishment procedure in the selected bandwidth part, performing connection establishment.
 
7. A method, comprising:
receiving, by a user equipment from a network node in a wireless network, an initial bandwidth part in system information;
receiving, an indication of at least one selected bandwidth part to be used by the user equipment during a connection establishment procedure to connect the user equipment to the wireless network, wherein the at least one selected bandwidth part is wider than the initial bandwidth part, wherein the at least one selected bandwidth part is received via paging or system information after the user equipment transitions to idle/inactive state, or in a release message prior to the user equipment transition to the idle/inactive state, the wider bandwidth part is utilized for an msg3 message of random access procedure; and
sending, by the user equipment and toward the network node, the msg3 message for connection establishment to the wireless network using the selected bandwidth part.
